EPA takes a great interest in the environmental implications of the manufacture of synthetic fuels , including coal liquefaction and gasification, retorting of oil shale, and the production of alcohol for fuel. Interest is also expressed in geothermal, solar, wind and tidal energy, combustion modification, coal and oil shale mining, energy conservation, fuel and energy transport and transmission, and new energy conversion systems such as ocean thermal gradients, magnetohydrodynamics, and fuel cells. In the area of pollution control guidance, the focal point of each regulation is intended to be a set of available control alternatives for each environmental discharge along with associated performance expectations and the basis for the alternatives presented. For most of the new energy technologies, exemplary full-scale and even pilot-scale waste treatment installations do not yet exist. A novel possibility now available is that of influencing in an environmentally productive way the choice by industry of the actual process technology to be commercialized and the overall designs of new plants, such that the most cost-effective environmental protection methods can be incorporated into the process design from the start. Specific energy technologies for which pollution control documents are now planned include low Btu coal gasification, indirect coal liquefaction, oil shale mining and processing, direct coal liquefaction, geothermal, medium Btu coal gasification, and high Btu coal gasification. Water-related environmental problems with synthetic fuels are also being studied, including the management of solid wastes from the production processes.

The application of ecological models to the Lake Michigan basin was the central focus of this research. A modified version of a deterministic phytoplankton mode, Lake 1 by Thomann, was first calibrated to the 1976 Lake Michigan field data. A dynamic phytoplankton simulation model (MICHI) was developed to investigate the observed field data and to use in forecasting lake responses to various phosphorus loading scenarios. The 1977 data indicated that the southern basin of Lake Michigan lost up to 3 micrograms of phosphorus per liter compared to concentrations observed in 1976. In an attempt to simulate this rapid depletion of phosphorus, MICHI required an implicit representation of suspected effects of an extensive ice cover observed during the winter of 1976-77. This included increasing the net apparent settling rate eight fold during ice cover. A total phosphorus model was used in conjunction with MICHI for forecasting. These forecasts indicate a steady-state total phosphorus concentration of 7 micrograms phosphorus per liter, given the target load recommended by the 1978 Water Quality Agreement. The projected time to obtain 95% of steady-state response to a load change was 7-14 years. (Baker-FRC) JF - Journal of Great Lakes Research Vol 7, No 4, p 467-480, 1981. 10 Fig, 3 Tab, 43 Ref.

The multi-class phytoplankton simulation model was set to field data acquired on Saginaw Bay, Lake Huron, during 1974. The concept of a single limiting factor for phytoplankton growth was found to be overly simplistic. Results indicated that temperature and light were relatively more growth rate limiting than nutrients on an annual average bases. However, as a consequence of nutrient depletion, nutrients became relatively more important at the times of peak phytoplankton crops. Nitrogen was more growth rate limiting than phosphorus to the total phytoplankton crop, although important differences occurred among the individual functional groups. While nitrogen and silicon were important in phytoplankton-nutrient dynamics, the supply of phosphorus would ultimately determine the size of the blue-green component of the total crop because nitrogen fixing blue-greens did not have absolute requirements for dissolved available nitrogen or silicon. Phosphorus requirements for summer crops were satisfied by recycle processes within the water column. Phytoplankton production was extremely sensitive to variation in the light extinction coefficient in the water column and relatively insensitive to variations in incident solar radiation.

This method can remove up to 99.9% of some organic toxic pollutants which are difficult to remove by steam or inert gas stripping or activated carbon adsorption. Capital expenditures for a 400 gpm solvent extraction system are given as $2 million. Part of this cost may be offset by recovery of marketable organic compounds. Tables give distribution coefficients for 89 organic pollutants in the following solvents: tricresyl phosphate, undecane, methyl isobutyl ketone, tridecane, benzene, isobutylene, isobutane, n-butyl acetate, isobutyl acetate, diisopropyl ether, octanol, cumene, mesityl oxide, methyl ethyl ketone, ethyl acetate, ethyl ether, ethyl benzene, n-hexanol, EDC, toluene, xylene, and n-hexane. The pollutants include chlorinated hydrocarbons, phenols, aromatic compounds, polycyclic aromatic compounds, amines, phthalates, and pesticides.

Biodegradation of toxic chemical substances is best described by Grau kinetics. An estimate of mass transfer coefficients in air stripping can be obtained from the ratio of the diffusion coefficient, molecular weights, or critical volumes in conjunction with a known value of the mass transfer coefficient. Sludge adsorbs some priority pollutants, primarily polynuclear aromatic compounds, metals, and cyanides. The disappearance of a specific toxic pollutant in sludge in nonbiodegradable form can be represented by the multicomponent adsorption equation of Langmuir type based on the binary characterization of wastewater adsorption.

Data obtained from intensive pollutant sampling in the Grand River, flowing into Lake Michigan, were used as a comparison. On the basis of the root mean square error the best method was the unbiased stratified ratio estimator, recommended for use when concentration data are limited and daily river flow records are available. Other methods evaluated were five simple methods based on daily, monthly, quarterly, semiannual, and annual average concentrations. The complex methods generally were more adequate. These were based on concentrations from quarterly, semiannual, annual, and stratified regression on log flow. Accuracy was increased by including more samples from the high flow periods.

Disinfection rates are compared in terms of the times and concentrations required to achieve a specified degree of inactivation (e.g., 99%) of a given microorganism. Overall, ozone is the most efficient and least stable agent; chlorine dioxide is second in efficiency and stability; free chlorine is third in efficiency and stability, and chloramines are least efficient and most stable. Inactivation kinetics for E. coli, poliovirus 1, cell debris-associated poliovirus, and coliform bacteria are graphed for all the agents except ozone, which operates too quickly for convenient plotting. Ozone has been shown to effect greater than 99.999% reduction of E. coli in 10 sec at an initial concentration of 0.38 mg/l, and 99.7% reduction of poliovirus 1 in 10 sec at only 0.012 mg/l. The biocidal action of ozone and chloramines was only slightly affected by pH in the pH 6-9 range; that of chlorine declined rapidly as pH rose from 7-9, and that of chlorine dioxide rose as pH increased. The effects of particular microorganisms and dissolved salts on biocidal efficiency are also discussed. Laboratory studies simulating field conditions indicate that turbidity can shield microorganisms from disinfectants: e.g., viruses suspended with cell debris are protected from ozone. There is not yet sufficient information to recommend the replacement of chlorine with other disinfectants.

Regulations finalized by EPA on November 29, 1979, set forth a maximum contaminant level of 0.10 mg/l for total THMs, and require monitoring and reporting of THM levels at quarterly intervals. Control strategies include use of a disinfectant that, unlike chlorine, does not generate THMs (chloramines, chlorine dioxide, ozone), reduction of THM precursors prior to chlorination, or reduction of THMs after formation. By 1977, ozone was the perferred disinfectant in more than 1039 water treatment plants, mostly in Canada and Europe. Ozone is a more effective disinfectant than chlorine, does not produce THMs, and can also be used to remove THM precursors prior to conventional chlorination. Precursors can be removed by direct ozonation or by using ozone to improve the removal efficiency of coagulation, settling, or filtration units. A summary of data from pilot studies showing THM precursor removal efficiencies of up to 80% is presented. Disadvantages of ozone compared to chlorine include limited residual disinfectant protection (sometimes leading to aftergrowth problems), higher costs, and the potential for forming organic byproducts with unknown health risks. Consideration of ozone 's ability to remove THM precursors while improving the efficiency of other unit processes is likely to reduce its price disadvantage.

A survey of 19 municipal and 17 recreational package water treatment systems produced the following performance data: pH, 6.5-8.6; coliforms, present in 3 of 31 systems; turbidity, 8 of 31 exceeding maximum federal standards; trihalomethanes, 5 of 31 exceeding 0.10 mg per liter; pesticides, none; silver, 2 systems; mercury, less than 0.001 mg per liter in several plants and 0.020 mg per liter in 1 municipal plant. Most aberrations in performance were ascribed to operator inattention or intermittent operation. Most package plants serve populations of 10,000 or less and have a capacity of 1.5 mgd or less. Comparative costs of a 1 million gallon per day conventional plant versus a package plant showed that the package plant was more economical. Construction costs for a conventional plant were $1,120,000 and annual operating and maintenance costs, $63 ,000; package plant, $488,000 and $40,000 respectively.

The procedure uses purge- and trap sample concentration followed by GC/MS analysis. Data reduction is performed by a computerized GC/MS data system. The quantification limits, precision and accuracy of these analyses have been demonstrated to be comparable to gas chromatography coupled with electrolytic conductivity and flame ionization detection. The analytical scheme permits the routine qualitative and quantitative analysis of 16 commonly occurring purgeable compounds over a concentration range of 0.1-0.2 to 0.5 micrograms/liter. Additional compounds can be analyzed by incorporating appropriate analytical standards.

Samples were analyzed for total organic carbon (TOC) using the Dohrmann TOC system. Three analyses were conducted for purgeable halogenated organics: instantaneous trihalomethanes (THM), simulated distribution THM, and THM formation potential. Response profiles from capillary column gas chromatographic analysis of influent and effluent samples from operating GAC beds were used to qualitatively judge adsorber performance. TOC results can serve as an operating guide at a given location if proper relationships can be established with TOC levels and concentrations of other substances. GAC reduced the simulated distribution THM concentrations and organic halogen levels, but the performance of the GAC system varied with changing influent conditions. Other drawbacks of the organic analysis of GAC performance include the requirement for subjective interpretation of some outputs and difficulties in managing large amounts of data.

An inert gas is bubbled through the sample. Those organohalides and other organic constituents which boil at less than 200 degrees C, are removed from the aqueous phase and trapped in a short column containing a sorbant combination. After a predetermined time, the trapped components are thermally desorbed, backflushed onto the head of a gas chromatograph and separated under programmed conditions. Measurement is done with a halogen-specific detector. The method is useful for determination of carbon tetrachloride, 1,2-dichloroethane, tetrachloroethylene, 1,1 ,1-trichloroethane, trichloroethylene, vinyl chloride, and 44 additional halogenated compounds listed in a table. The method, useful for detection and measurement of multicomponent mixtures spiked into carbon filtered finished water and raw source water at concentrations of 0.20-0.40 micrograms per liter, has detection limits of < 0.01 micrograms per liter. The compounds listed in the table can be accurately measured over a concentration range of 0.10-5.0 micrograms per liter. Individual organohalides can be determined at concentrations up to 1500 micrograms per liter. JF - EPA Report No. 600/4-81-059 1981. 50 p, 7 Fig, 4 Tab, 3 Ref.

The wastewater samples are screened for organics by analyses of five fractions: pesticides (26 compounds), base/neutrals (46 compounds), acids (11 phenols), purgeables (29 volatile organics), and direct aqueous injection (2 compounds). Except for purgeable organics, overall recovery decreases and the relative standard deviation increases in going from the method standard to the matrix spiked analysis. Analysis of purgeable and acid organic compounds produces the highest recoveries with the smallest matrix effect. The analysis of base/neutral compounds and pesticides gives the lowest recoveries because they react among each other and with hydroxide and water. Base/neutral compounds also carry over into the acid fraction in the presence of emulsions. Analysis of purgeable organics by the EPA protocol has been most successful; acid and pesticide analyses, moderately successful; and base/neutral analysis less successful, especially with samples from the leather tanning and timber industries. Metals analyses are not difficult at the 25 ppb level used. Analyses of several compounds presented problems and are recommended for further investigation: dichloromethane, bis(chloromethyl) ether, N-nitrosodimethylamine, di-n-butylphthalate, bis(2-ethylhexyl) phthalate, 1,2-diphenylhydrazine, benzidine, hexachlorocyclopentadine, endrin aldehyde, anthrene and phenanthrene, chrysene and benzo(a)anthracene, and benzo(b)fluoranthrene and benzo(k)fluoranthrene.

AN - 15553756; 402872 AB - Since arsenic is a significant compound of ores processed in the nonferrous metals industry, it is of interest to characterize and evaluate control strategies which have demonstrated the potential for lowering the emission rates of arsenic and other hazardous effluents from smelter operations. The Campbell Red Lake Mines Gold Smelter at Balmerton, Ontario, Canada, has developed and implemented a successful control strategy for arsenic emissions from a nonferrous smelting operation. The control system was designed and installed by Hatch Associates, Toronto, Canada. The Red Lake smelter uses cyclones and a hot electrostatic precipitator to recover metal values from roaster dusts with subsequent air quenching to condense (or desublime) arsenic trioxide which is recovered in a low-temperature baghouse. This paper is a review of a test program conducted at Red Lake designed to characterize the control systems and to evaluate the potential for transferring the technology to smelting operations in the United States.

AN - 15542767; 396524 AB - A 566 m super(3)/m permanent installation demonstration system, consisting of the Air Pollution Systems' High Intensity Ionizer and a variable throat venturi scrubber has been installed on a magnesium recovery furnace. The furnace produces submicron fume particles of MgO, MgCl sub(2), and ZrCl sub(4). The system is designed to demonstrate the effectiveness of the High Intensity Ionizer versus high venturi pressure drop on the furnace emissions. The High Intensity Ionizer array operates stably at field strengths of 10-15 kV/cm and at velocities in excess of 18 m/sec while maintaining high charging efficiencies. The report covers the system design, technology, applications, and project developments. An Environmental Protection Agency proposed charged droplet Scrub-E is also discussed covering the design, technology, and proposed demonstration program.

AN - 15518031; 349201 AB - Accurate estimates of pollutant loadings to the Great Lakes are required for trend detection, model development, and planning. On many major rivers, infrequent sampling of most pollutants makes these estimates difficult. However, most large rivers have complete daily flow records available from the U.S. Geological Survey. A number of different estimation methods have been developed to use these data in conjunction with available concentration data to calculate pollutant loadings. Several of these methods have been evaluated in this paper for a typical major tributary. Intensive measurements of pollutant loadings to Lake Michigan from the Grand River in 1976-1977 were conducted by USEPA, Region V. Daily concentrations of several chemical parameters, including total phosphorus, were determined. This information, together with daily river flow rates from USGS, provide an excellent data set for testing various load estimation methods. Ten different methods were tested using 680 randomly generated 25-sample subsets of the daily total phosphorus data set. The methods tested included several simple calculation schemes, as well as flow-concentration correlations and the stratified ratio estimator. The latter method is shown to be at least slightly better than the others for these data and for this type of sampling, including when sampling is concentrated during periods of high flow.

AN - 15497616; 321674 AB - The Clean Air Act, as amended in 1977, requires periodic review and revision of all national ambient air quality standards (NAAQS) to insure that they are based on the latest scientific information. A possible framework for analyzing health risks associated with attainment of alternative NAAQS is described. The framework consists of three phases of analysis for supporting future regulatory decisions on NAAQS: (1) a scientific assessment phase, (2) a risk assessment phase, and (3) a risk evaluation and decision analyses phase. The proper separation of roles among scientists, risk analysts, and decision analysts is also addressed. The author concludes that despite several possible pitfalls, the adoption of formal risk analysis approaches can greatly facilitate communication between scientists and decision makers and decision makers and the public in areas involving scientific uncertainties.

AN - 15496353; 327952 AB - The National Park Service and the U.S. Environmental Protection Agency are cooperatively conducting ongoing studies of human perception of visual air quality. Major objectives of this program include: (1) determination of the relationship between judgments of visual air quality of actual three dimensional scenes and a surrogate slide representation of that scene, (2) examination of the effect of sun angle and meteorological conditions on perceived visual air quality, (3) examination of the effect of demographic background on observer's judgments of visual air quality, (4) establishment of a functional relationship between human perception of visual air quality and various electro-optical parameters for several different scenic vistas and (5) development of a model capable of predicting the sensitivity of a park to visual air pollution impact. Preliminary results of a previous study involving one vista revealed a linear relationship between human perception and apparent vista contrast for constant vista illumination and ground cover. A more general formalism for averaging vista color contrast appeared to account for effects that snow cover and varying illumination have on the sensitivity of perceived visual air quality to air pollution.

AN - 15488145; 294887 AB - This paper evaluates from an ex post perspective the economic viability of a pilot irrigation project in northern Senegal which has been in operation since mid-1975. The authors begin by presenting the international context within which the Nianga Project developed, namely, the donor agencies were called upon to fund additional tertiary (i.e., full water control) irrigation projects in the Senegal River Valley in the absence of any rigorous economic analysis of this type of irrigation project. Next, they briefly describe first the project milieu and then the development and operation of the project itself. From the descriptive they pass to the analytic mode, wherein the project is formally evaluated with the techniques of social cost benefit analysis (SCB); and subsequently, they compare the ex ante feasibility study and the present ex post analysis. Finally, on the basis of the results from the latter, they draw some policy implications for future irrigation development in the Senegal River Valley. JF - J. DEVELOP. AREAS.

AN - 15484325; 294886 AB - In discussing an approach to assessing the health risks that would obtain if various possible primary national ambient air quality standards were met, it is important to distinguish appropriate principles for probabilistic risk assessments from principles for the scientific research and scientific assessments on which they are based. Appropriate principles for probabilistic assessment are derived from the ultimate objective of maximizing the amount of control societal decision-making agents have in making environmental trade-offs under uncertainty about the effect of their decisions. A general methodology is presented which implements these first principles. Two general risk models are presented: a relatively simple benchmark risk model and a more complex head count risk model. These general risk models serve as a guide for the development of specific operational risk models applicable to particular ambient pollutants. Examples are given of different specific models needed for different types of pollutants. Since the scale on which a specific methodology is implemented is not determined by the methodology, the various choices involved in deciding the scale of a specific application are addressed.

AN - 15464158; 271221 AB - EPA's airborne downlooking dye lidar was operated during the STATE field program in western Kentucky/Tennessee in the summer of 1978. In this paper, lidar estimates of height of the atmospheric mixing layer are shown and compared with in situ measurements. Lidar estimates of crosswind and vertical dimensions of TVA power plant plumes are compared with appropriate literature values and with in situ estimates from data compiled by other STATE investigators; wherever necessary, data are adjusted to ensure compatibility with respect to sampling time.In addition, lidar measurements of plume rise are compared with model calculations. The lidar estimates of mixing layer height were usually slightly higher than in situ counterparts, presumably because aerosols may rise and become trapped above the base of the elevated stable layer. Values of plume rise computed using the Briggs models were generally similar to those indicated from lidar measurements although considerable scattering of data existed; supplementary data indicated that the scatter could be reduced with the inclusion of the vertical shear of the horizontal wind in the models.

AN - 15453791; 268587 AB - N-Methyl-4-aminoazobenzene (MAB) is believed to be metabolized in the liver to an electrophilic N-sulfonyloxy ester which binds covalently to cellular macromolecules, resulting in the induction of hepatic neoplasia. Since a single dose of MAB is not sufficient for complete carcinogenic activity, the authors sought to identify the MAB-DNA adducts present in rat liver after multiple oral doses of ( super(3)H) MAB. The MAB was administered by intubation at a level of 0.2 mmol/kg for 1, 3 or 4 doses and animals were sacrificed at 8 h after the last dose. Hepatic DNA was isolated by extraction and hydroxylapatite chromatography and was enzymatically hydrolyzed to MAB-mononucleoside adducts, which were quantitated by high pressure liquid chromatography (HPLC).

AN - 15432323; 250692 AB - The U.S. Environmental Protection Agency, National Park Service, Visibility Research Center, and University of California at Davis are currently operating a monitoring program in national parks and monuments throughout much of the western United States. Project VIEW, the Visibility Investigative Experiment in the West, includes measurement of visibility parameters using manual telephotometers, and measurement of particle concentrations averaged over 72 h. Variation of these parameters occurs in both space and time. To better understand these variations, several techniques including principal component analysis and data comparisons among sites are applied to Fall, 1979 data for much of the network. Then the Grand Canyon is chosen for additional analysis. Best and worst case visibility days are determined and compared with particle concentrations. Finally, hypothetical causes for visibility reduction are further verified by computing wind trajectories back in time for these special case days.

AN - 15423899; 234520 AB - Adult male, inbred, disease-free cats of uniform age and size were exposed eight hours per day, seven days per week to a 1:18 dilution of diesel exhaust emissions. After one year of exposure, the animals were removed from the chambers for measurement of lung volumes, forced expiratory flow rates, dynamic compliance and resistance, diffusing capacity, and nitrogen washout. No important changes in pulmonary function were detected with the exception of a decrease in closing volume (P<0.05). The inability to detect decrements in pulmonary function may have been due to insufficient concentration of exhaust, insufficient exposure length, or to the use of a species resistant to diesel exhaust. To test these possibilities, the cats are being exposed for an additional year, and another species, hamsters, are being exposed for future testing at exhaust dilutions of 1:18 and 1:9.

The methodology is based on procedures used to determine purgeable organic compounds in water and wastewater. Fish tissue is added to reagent water, cooled in an ice bath, and homogenized with cell disruption using ultrasonic energy. The processed sample is then analyzed by a purge and trap procedure using an impinger-type device at 70 degree C, with determination of the purged compounds by computerized gas chromatography-mass spectrometry.

AN - 15410095; 234774 AB - In the initiation/promotion assay in rat liver, partial hepatectomy is used to enhance initiation, and a choline-devoid diet as promoter. The induction of carcinogenesis is determined by the focal appearance of gamma glutamyl transpeptidase (GGT) positive hepatocytes. The authors adopted this assay to diesel exhaust emission by performing a 2/3 partial hepatectomy, and exposing the rats to either clean air or diesel exhaust emission. The rats were fed either a choline-devoid or a choline-supplemented diet for three or six months. The animals were sacrificed and liver sections stained for GGT were examined for the presence of foci of GGT(+) hepatocytes. The results indicate that diesel exhaust exposure does not result in a systemic dose of carcinogens sufficient to be detected in the liver foci assay.

AN - 15405322; 218244 AB - Several experiments examining the effects of diesel exhaust on the behavior of rats are reported. Animals were exposed either as adults or neonates. The spontaneous locomotor activity (SLA), measured in standard running wheel cages, of adult rats exposed for 8 h/day, 7 days/week was significantly less than that of controls. Experiments involving diesel exhaust exposure to neonatal rats indicated that adult rats, exposed to diesel exhaust during their neonatal lives, were significantly less active as measured by SLA. Adult rats, exposed to 20 h diesel per day as neonates, were placed in skinner boxes after the SLA experiment described above had been completed. The exhaust exposed animals showed significantly decreased acquisition of a food reinforced bar pressing task. All animals that learned this task extinguished at the same rate. The results of the neonatal diesel exhaust experiments support the hypothesis that diesel exhaust exposure during development of an organism can lead to behavioral differences in adulthood.

AN - 15402709; 218260 AB - A series of experiments was conducted in which groups of mice were first exposed for various durations to diluted exhaust from light duty diesel engines and then briefly to an infectious aerosol generated by nebulizing cultures of a bacterial pathogen (Streptococcus ). Typically, postinfection mortality was signigicantly greater in groups exposed to exhaust than in their corresponding control groups exposed to purified air only. Data of recent diesel and of past diesel- and catalyst-treated gasoline engine exhaust experiments suggest a somewhat grreater excess mortality from (enhanced susceptibility to) bacterial infection in mice exposed to diesel exhaust than in those exposed to catalytic gasoline exhaust. Limited data on acute tests of NO sub(2) and acrolein vapor alone suggest that the infectivity-enhancing effect of diesel exhaust could be accounted for in large part by these components. Exposures to diesel exhaust, NO sub(2), or acrolein did not enhance the mortality response to a viral pathogen (A/PR8-34).

AN - 15400348; 218920 AB - A major diesel emissions research program has been initiated by the US Environmental Protection Agency to assess the human health risk associated with increased use of diesel automobiles. This program is intended to establish the mutagenic and carcinogenic potency of complex organics associated with diesel particles as well as comparative particle-bound organics from other environmental emissions for which human epidemiological data are available. The mobile source samples selected for this study were collected from a heavy-duty diesel engine, a series of light-duty diesel passenger cars, and a gasoline catalyst automobile. The comparative source samples incorporated into the study were cigarette smoke condensate, coke oven emissions, roofing tar emissions, and benzo(a)pyrene. The samples were tested using three mutagenic assays and four carcinogenic assays as prescribed by a test matrix. This report describes the study design, particle generation, and sample collection and preparation. A brief summary of the bioassays is also included.

AN - 15398191; 213639 AB - The proposed conversion from gasoline powered automobiles to diesel powered vehicles has prompted the Environmental Protection Agency to evaluate the potential health effects associated with exposure to diesel emissions. At present, there is no direct epidemiological link between this exposure and human health. Therefore, a research program was constructed to compare the health effects associated with diesel emissions with those from other emission sources for which epidemiological information was available. The emission sources chosen chosen were cigarette smoke, roofing tar, and coke oven. An additional comparative emission source which was evaluated, was a gasoline catalyst engie. Respirable particles from a variety of combustion sources have the potential of being carcinogenic and mutagenic. The objective of these studies was to determine the relative biological activity of the organic material adsorbed on these particles in both in vitro mutagenesis and in vitro and in vivo carcinogenesis bioassays.

AN - 15395407; 215420 AB - Data in twelve power plant and smelter plumes reported by eight different organizations have been reviewed in an attempt to establish the existence of recognizable patterns concerning the extent and rates of sulfate formation. The data reviewed here were collected in Australia, Canada and the U.S., during warm as well as cold seasons, and during day and night. The primary variables examined and compared are S sub(p)/S sub(T), the particulate fraction of excess sulfur sampled in the plume, and the corresponding plume age. The variation of the extent of sulfate formation (S sub(p)/S sub(T)) is also examined in terms of plume exposure to solar radiation dose during transport. In spite of wide geographical, seasonal, background and source variations, a distinct difference is observed in day and night sulfate formation. During the daytime, there exists a substantial variability in sulfate formation rates (typically 0-5%h super(-1)) and extent (typically up to 25%) for any given physical plume age. This variability is significantly less for plumes with similar exposure to sunlight dose, showing that environmental factors linked to solar radiation strongly influence the rate and extent of sulfate formation in point-source plumes.

AN - 15391708; 214155 AB - Female Swiss mice were exposed 8 h/day to diesel exhaust for 1, 3, and 7 weeks. Urine was collected overnight for 4 days prior to sacrifice while the mice continued to be exposed for eight hours during the day. The presence of mutagens was determined by the Ames Salmonella test. One hour prior to sacrifice each mouse received 1 mg/kg colcemide. After sacrifice, the marrow from each femur was obtained. The marrow from one femur was used to prepare slides for metaphase analysis and the other for micronuclei assay. Other mice received IP 50 mg/kg cyclophosphamide 24 h prior to sacrifice or 1 mu mole/kg benzo(a)pyrene in each of four daily doses prior to sacrifice and served as positive controls. The Ames Salmonella assay of the unconcentrated urine after 1, 3, and 7 weeks and concentrated urine after 7 weeks exposure to diesel exhaust did not significantly vary from clean air controls. In the micronucleus test, and metaphase analysis, cyclophosphamide produced a strong positive response and the 7 week diesel exposure was not different from clean air controls.

AN - 15390292; 214112 AB - Male Chinese hamsters were exposed to diesel exhaust and clean air for six months at the Center Hill Facility of the U.S. Environmental Protection Agency in Cincinnati, Ohio. The animals were kept in specially constructed inhalation chambers and exposed to clean air or diesel exhaust for eight hours daily. The animals were sacrificed and slides prepared to study the mutagenic effects of diesel exhaust by four in vivo short term mammalian bioassays. Sperm morphology bioassay revealed a 2.67-fold increase in sperm abnormalities in the animals exposed to diesel exhaust as compared to those exposed to fresh air. Micronucleus bioassay revealed a 50% increase in the number of micronuclei in polychromatic erythrocytes obtained from animals exposed to diesel exhaust.

AN - 15388184; 213159 AB - It is the major intent of this report to examine the animal inhalation facilities at the EPA Health Effects Research Laboratory in Cincinnati, Ohio, associated with the exposure to the exhaust of diesel-powered equipment. The facility serves as a center for toxicologic evaluation, in relevant animal models, of potentially hazardous environmental pollutants from diesel engine exhaust. Briefly, the entire engine exhaust is mixed with filtered and conditioned air in a dilution tube. That diluted exhaust enters a large volume mixing chamber and a portion passes through dynamic flow irradiation chambers (to simulate sunlight) and is then conducted to animal exposure chambers. The system provides nonirradiated exhaust in the same concentration (directly from the mixing chamber) and also filtered, conditioned ambient air for control animal exposure. The major physical components of the diesel emission system include: air purifiers, animal exposure chambers, engine-dynamometers, irradiation chambers, monitoring instrumentation and data acquisition systems.

AN - 15388110; 213257 AB - The biochemical response to controlled exposures of nitrogen dioxide (NO sub(2)) was studied in 19 human subjects exposed to 0.2 ppm NO sub(2) for 2 hr and compared to 15 control subjects exposed to filtered air for 2 hr. Seven biochemical blood parameters, including glutathione, red blood cell glutathione reductase, 2,3-diphosphoglycerate, methemoglobin, vitamin E, complement C sub(3), and IgA were measured prior to exposure, immediately after exposure, and 22 hr following exposure. The only variable that showed significant change due to NO sub(2) exposure was glutathione. Glutathione is known to protect the erythrocyte from oxidative stress. The increase in glutathione observed upon exposure to NO sub(2) may be a protective reaction of the erythrocyte to meet the oxidative stress. JF - ARCHIVES ENVIRON. HEALTH.

AN - 15385930; 215054 AB - Due to the expected increase in the percentage of diesel vehicles in the United States, the Environmental Protection Agency must evaluate the health effects associated with exposure to diesel emissions. Respirable particles from a variety of combustion sources have the potential of being carcinogenic and mutagenic. The objective of these studies was to determine the relative biological activity of the organic material adsorbed on these particles in in vitro mutagenesis bioassays. The organic extracts from the following series of emission sources were bioassayed in the Salmonella assay for mutagenic activity: (1) a light-duty Oldsmobile diesel 350 engine; (2) a heavy-duty Caterpillar diesel engine; (3) a light-duty Nissan engine; (4) a Volkswagen Rabbit diesel engine; (5) cigarette smoke; (6) roofing tar; (7) coke oven; and (8) a gasoline catalyst Mustang. This paper provides a comparison of these sources within the Salmonella bioassay and also demonstrates how bacterial systems can be used as a quality assurance measure in in vivo testing.

AN - 15374616; 197492 AB - The disposition of super(14)C-labeled methylparathion, parathion, and p-nitrophenol applied as a foliar spray was examined in the Terrestrial Microcosm Chamber (TMC) and compared to a reference compound, dieldrin. The impact of soil type (synthetic vs. natural) and airflow rates through the chamber on methylparathion disposition was evaluated. The TMC contained either a synthetic soil medium or Willamette sandy loam soil plus agricultural crops, numerous invertebrates, and a gravid gray-tailed vole (Microtus canicaudus ). Dieldrin was accumulated to a lesser extent than any of the organophosphates in the synthetic soil. Concentrations of methylparathion in the upper layer of Willamette sandy loam soil were consistently lower than those observed with the synthetic medium. Increased airflows altered methylparathion distribution primarily through increased export from the TMC.

AN - 15371606; 198213 AB - The persistence and disappearance (washoff or dryfall) of methoxychlor (2,2-bis(p-methozyphenyl)-1,1,1-trichloroethane) from mature soybean (Glycine max (L.) Merrill) foliage was investigated in a small field plot study under natural rainfall conditions in 1977 and 1978. Residue analyses were conducted using whole plant samples. The amount of dryfall was significantly greater in plots entered by workers than in those where entry was avoided. Statistical analyses indicated that within-sample variation for mechanical chopping of plant samples was significantly smaller at the 5% level than for a hand chopping method. Results from this study will be useful in defining research objectives for the development of algorithms to describe the behavior of foliar-applied compounds. Such algorithms are necessary for estimating runoff losses of insecticides to water bodies. JF - J. ENVIRON. SCI. HEALTH.

AN - 15369938; 197646 AB - Before development of an emission standard for vinyl chloride, the Environmental Protection Agency (EPA) conducted three programs to measure vinyl chloride (VC) concentrations in air around plants which either manufacture VC or use it. A brief monitoring survey conducted by EPA Regional Offices found VC in ambient air around poly(vinyl chloride) (PVC) production plants. As a consequence of this survey, a second monitoring program was established to measure VC in the air around VC and PVC production plants. This program found some relatively high concentrations of VC in ambient air around the plants. This program found maximum 24-hr average concentrations ranging from 0.32 to 10.6 parts of VC per million parts of air. The program also found an apparent relationship between certain emission excursions and ambient VC concentrations. A third monitoring program was established to measure VC around PVC fabrication plants. This monitoring program found much less VC around PVC fabrication plants than around VC and PVC production plants.

AN - 15369398; 197721 AB - In regulation of exposures to hazardous environmental agents, epidemiologic evidence is especially important in defining human risk estimates. The process of developing appropriate regulations is complex, however, and depends on many considerations beyond those established to a high degree of scientific certainty. Thus the needs of regulatory agencies are involved in the way epidemiologic data are developed and presented. To coordinate and review common problems associated with preventive and regulatory activities among the federal agencies concerned with regulation, and Interagency Regulatory Liaison Group (IRLG) was established in 1977. Because of difficulties encountered by these agencies or Congressional committees in evaluating epidemiologic evidence, a subcommittee of the IRLG has developed in draft form guidelines for human population studies to be used in public health decision-making. Although these guidelines have attracted much controversy, their aim is to present criteria for design and documentation of epidemiologic studies, without interfering with the initiative of investigators.

AN - 15366523; 198116 AB - This study was designed to reveal patterns of response of major United States crops to sulfuric acid rain. Potted plants were grown in field chambers and exposed to simulated sulfuric acid rain (pH 3.0, 3.5 or 4.0) or to a control rain (pH 5.6). At harvest, the weights of the marketable portion, total aboveground portion and roots were determined for 28 crops. Of these, marketable yield production was inhibited for 5 crops (radish, beet, carrot, mustard greens, broccoli), stimulated for 6 crops (tomato, green pepper, strawberry, alfalfa, orchardgrass, timothy), and ambiguously affected for 1 crop (potato). In addition, stem and leaf production of sweet corn was stimulated. Visible injury of tomatoes might have decreased their marketability. No statistically significant effects on yield were observed for the other 15 crops. The results suggest that the likelihood of yield being affected by acid rain depends on the part of the plant utilized, as well as on species. Effects on the aboveground portion of crops and on roots are also presented. JF - ENVIRON. & EXPER. BOTANY.

The initial evaluation of this test system was accomplished using cadmium chloride, chromium chloride, cobalt chloride, mercuric chloride, nickelous chloride, sodium arsenite, sodium selenite, and ammonium vanadate. The relative toxicity of the compounds was as follows: Cd > V = As > Se > Hg > Cr = Co > Ni. Since several of the compounds with very similar EC sub(50)s had significantly different dose response slopes, an additional parameter, lowest effective concentration tested (LECT) was employed to assess the relative toxicity. The LECT was determined using the Williams test and the relative toxicity of the compounds was found to be Cd = Se > V > As = Hg > Co > Cr = Ni. JF - IN VITRO, J. TISSUE CULT. ASSOC.

AN - 15351917; 173160 AB - The effects of ozone (O sub(3)) on cell-mediated immunity were studied in 16 human subjects exposed to 1176 mu g/m super(3) O sub(3) (0.6 ppm) for 2 hr in an environmentally controlled exposure chamber. Venous blood samples were taken before and immediately after controlled air and O sub(3) exposures, as well as at 72 hr, 2 and 4 weeks, and at one random time at least 1 month after treatment. No statistically significant changes were observed in the number of T lymphocytes that form spontaneous rosettes with sheep erythrocytes. The response of T lymphocytes to PHA was significantly reduced in samples taken at 2 and 4 weeks following O sub(3) exposure. Normal response to PHA was observed at 2 months post-O sub(3) exposure. No statistically significant changes in lymphocyte responses to Con A, PWM, or Candida) were seen. These results show that one 2 hr exposure of humans to 0.6 ppm O sub(3) may lead to a transient suppression of the PHA-stimulated blastogenic transformation of peripheral blood lymphocytes. The data indicate that the blastogenic response to PHA of human lymphocytes is exquisitely sensitive to O sub(3) exposure and could serve as a bioassay for evaluating subtle changes in cellular immunity induced by O sub(3) and possible other pollutants.

With the size parameters of the modes taken to be the "grand average continental" values of Whitby, the upper size limit is 3.4 mu m (aerodynamic diameter). Consequently, the extinction coefficient could be inferred from a measurement of the fine mass concentration only, even in arid regions where coarse aerosol concentrations usually far exceed the fine.

AN - 15346261; 166317 AB - Extensive research has determined that adipic acid, when used as an additive to a limestone flue gas desulfurizaiton (FGD) system, will improve the performance of the system. Both SO sub(2) removal and limestone utilization can be greatly increased by the buffering effect of adipic acid. Successful testing in laboratory, bench, pilot, prototype, and full scale systems has demonstrated the benefits of this technology for new and retrofit applications. Although adipic acid does degrade in the scrubber, no significant operating problems or environmental impacts have been identified.

I. Slow Cortical Potentials. AN - 15340782; 164313 AB - The effects of body Pb burden on slow cortical potentials were studied in 63 children aged 13-75 months. Slow wave (SW) voltage during sensory conditioning varied as a linear function of blood lead (PbB) level. The slope of this function, moreover, changed systematically with age. For children under 5 years of age, SW voltage tended to be positive at low PbBs and to be negative above 30 mu g/dl. For children over 5 years of age, SW voltage tended to be negative at low PbBs and to be less negative (or positive) above 30 mu g/dl. These results provide evidence of altered CNS function at the lowest Pb effect level ever reported. JF - ELECTROCEPHALOGR. CLIN. NEUROGHYSIOL.

AN - 15339932; 167501 AB - Diethyl was determined in water and sediment by high performance liquid chromatography (HPLC) and in water by gas-liquid chromatography with electron capture detection (GLC-EDC). Water samples were extracted with hexane, using a high-speed homogenizer-ultrasonic apparatus and a test tube mixer. Sediments were Soxhlet-extracted using acetonitrile. For HPLC, diethyl phtalate was determined in normal phase mode using a Zorbax-CN column, a 2% isopropanol-hexane solvent system, and a UV variable wavelength detector. For GLC-ECD, a 3% SE-30 Gas-Chrom Q column with a super(63)Ni electron capture detection system was used. Recoveries from fortified samples ranged from 93.9 to 98.0% for water at 0.01-0.50 ppm, and from 90.0 to 93.6% for sediment at 0.2-2.0 ppm.

Fetal and maternal toxicity was observed in both species. In the mouse, maternal toxicity was observed in both species. In the mouse, maternal toxicity was evident at the lowest dose, while teratogenic response was confined to cleft palate at 400 and 600 mg/kg/day. The effective maternal toxic dose in the rat was 40 mg/kg/day. In this species, incidence of irregular palatine rugae was significantly dose-related. The results suggest an "apparent no effect level" for this anomaly below 30 mg/kg/day. JF - Drug and Chemical Toxicology AU - Rogers, E H AU - Chernoff, N AU - Kavlock, R J AD - Exp. Biol.

II. EEG Spectra. AN - 15339740; 164338 AB - This sutdy explored the effect of age and PbB upon EEG power spectraand various measures of hemispheric laterality in children, ages 13-75 months. The delta - and theta -band amplitude decreased with age. When only bilaterally synchronized EEG between P3 and P4 was considered the amplitude of P3 was estimated as greater than P4 in all frequency bands and for all ages. Previous reports have not shown lateral EEG dominance in children below 75 months. When lateral dominance measures consider only the ralationship between synchronized EEG at P3 and P4, bilateral communality in the delta band increased with age. Increased PbB generally produced an increase in the relative amplitude of synchronized EEG between P3 and P4 in all frequency bands. This was true for PbB levels well below 15 mu g/dl, among the lowest level PbB effects previously reported. No clinical or behavioral effects of PbB values have been reported below 15 mu g/dl.

AN - 15337443; 165697 AB - During the summer of 1979, coefficients for light extinction in the atmosphere were calculated from measurements made wtih a telephotometer placed 251 m from a black target in Research Triangle Park, North Carolina. The results are well crrelated (r = 0.92-0.96) with integrating nepnelometer measurements of scattering coeffiecients and are highly correlated ( r= 0.99) with daily arithmetic averages of sums of scattering and absorption coefficients. The average sume of scattering and absorption coefficients accounts for about 90% of the average telephotometrically measured extinction coefficient. Scattering by particles and scattering by air contribute 75 and 7% of the measured extinction coefficient; absorption by particles and absorption by nitrogen dioxide contribute 7 and 2% respectively. From measurements of the aerosol mass and elemental composition, it is inferred that sulfate and its cations account for at least 54% of the mass of particles smaller than 2.5 mu m in dia.

Chlorine dioxide is about on a par with hypochlorous acid, but in contrast of free residual chlorine, its efficiency increases substantially as pH increases in the range at which disinfection is usually applied. Chloramines are weaker biocides than hypochlorite ion, the least efficient form of free residual chlorine. Precise quantitative ranking of biocidal efficiencies is not possible beacuse efficiencies differ with different microorganisms and experimental conditions.

AN - 15335703; 154333 AB - Theories of light extinction and contrast reduction by atmospheric aerosol are reviewed. Errors inherent to telephotometry are analyzed. Significant errors may result from unknown target luminance, stray light within the telephotometer, and uneven illumination due to clouds. Measurements by a telephotometer of the extinction coefficient of the relatively turbid atmosphere of the eastern U.S.A. are described. Because of current levels of extinction, it is feasible to apply a dual target technique developed by Ruehle, which corrects for the targets' imperfect blackness and stray light imperfections in the telephotometer optics. The results compare favorably (r = 0.97, slope = 1.08) to independent measures of scattering and absorption coefficients when the most obvious cases of uneven illumination due to clouds are excluded. The agreement of these two independent measurement methods for extinction coefficient lends credence to them both. However, the difficulty of automating cloud detection for the telephotometer remains a formidable practical problem. JF - Atmospheric Environment AU - Ellestad, T G AU - Speer, R E AD - Environ. Sci.

AN - 15333678; 163101 AB - Water filtration processes can reduce the asbestos fiber count in drinking water by 90 to 99.9 percent, or more. Effective fiber removal requires very close control of the treatment process. Monitoring of filtered water turbidity can indicate the efficacy of treatment, even though the asbestos fiber concentration is too low to register as turbidity. Turbidity monitoring works because when water is properly prepared for filtration, passage of asbestos fibers through the filter is indicated by the passage of floc, as shown by higher turbidity. Filtered water turbidity should be 0.10 ntu or below for best fiber removal. Continuous monitoring of each filter module at a treatment plant is recommended. These findings are based on studes at Duluth, Two Harbors, and Silver Bay on Lake Superior; Seattle's Tolt reservior, and on data obtained from the San Francisco Bay area. JF - J. ENVIRON. ENG. DIV.

AN - 15332091; 154246 AB - Many Class I areas have unique vistas which require an observer to look over complex terrain containing basins, valleys and canyons. These topographic features tend to form pollution "basins" and "corridors" that trap and funnel air pollutants under certain meteorological conditions. For example, on numerous days, layers of haze in the San Juan River Basin obscure various vista elements including the Chuska Mountains as viewed from Mesa Verde National Park, CO. Measurements by an integrating nephelometer and a conventional teleradiometer at one location in Mesa Verde do not quantify the inhomogeneities. In this paper, data from these instruments are compared to data derived from scanning teleradiometer measurements of photographic slide images. The slides, surrogates of the real three-dimensional scene, were projected and scanned to determine relative sky and vista radiance at 40 points within a vertical slice of the vista. Comparison of the corresponding visual range data sets for each instrument for September and December 1979 demonstrates the utility of the scanning teleradiometer.

AN - 15327124; 157127 AB - Benzene exposures may affect human health in three ways: (1) increasing the incidence and severity of acute illness, (2) increasing the incidence and severity of chronic illness, and (3) increasing mortality rates. These adverse health effects result in tangible and intangible losses. Examples of tangible losses are time away from work, lower productivity during working hours, and use of medical resources. Intangible costs are the anxiety, pain and fear in individuals and their family and friends. These costs are seldom considered in an economic evaluation of adverse health effects. Information about the adverse health effects associated with benzene exposure is very limited as is evident from the section characterizing risk. There is no quantitative information about morbidity or mortality changes resulting from aplastic anemia nor morbidity changes resulting from leukemia. Thus, any attempt to assess the economic value of adverse health effects is limited to changes in mortality rates. JF - J. AIR POLLUT. CONTR. ASSOC.

AN - 15323635; 141245 AB - Although RCRA is the principal U.S. law governing hazardous wastes. The Toxic Substances Control Act (TSCA) also contains limited authority to regulate the export of chemicals and chemical wastes which are regulated domestically under TSCA if EPA finds the export will present an unreasonable risk of injury to the health or the environment within the United States. It is under TSCA that wastes contaminated with polychlorinated biphenyls (PCB's) or TCDD (dioxin) are controlled for export. Under present regulations, PCB's may not be exported for disposal unless the U.S. and the other country have entered into a Memorandum of Understanding which establishes mutually agreed upon criteria for their storage, transportation and disposal. At the present time there are no such Memoranda between the U.S. and any other nation, and exports and imports of PCB wastes are banned. For wastes containing TCDD, EPA requires a 60-day advance notice of shipment, and exports are dealt with on a case-by-case basis. JF - EPA Journal AU - Greider, W AD - EPA's Off. Int.

AN - 15319458; 137516 AB - Strains of E. coli recently isolated from human feces were examined for the frequency with which they accept an R factor (R1) from a derepressed fi super(+) strain of E. coli) K-12 and transfer it to fecal and laboratory strains. The majority of fecal E. coli isolates accepted the R factor at lower frequencies than K-12 F super(-). The frequencies with which certain fecal recipients received the R-plasmid were increased when its R super(+) transconjugant was either cured of the R1-plasmid and remated with the fi )strain or backcrossed into the parental strain. The former suggests the loss of an imcompatibility plasmid, and the latter suggests the modification of the R1-plasmid deoxyribonucleic acid (DNA). Passage of the R1-plasmid to strains of salmonellae reached mating frequencies of 10 super(-1) per donor cell when the recipient was a Salmonella typhi previously cured of its resident R-plasmid. However, two recently isolated strains of Salmonella accepted the R1-plasmid from E. coli K-12 R super(+) or the R super(+) E. coli) transconjugants at frequencies of 5x10 super(-7) or less.

Organic solvents were more efficient than physiological fluids in removing mutagens from diesel particles, with dichloromethane extracts having the greatest mutagenic activity of the solvents examined. Serum and lung cytosol were more effective than acellular lung lavage fluid in releasing mutagenic activity from diesel particles. The mutagenic activity of diesel particle organics preextracted with dichloromethane is greatly reduced upon the addition of serum and lung cytosol to organics.

AN - 15293838; 122634 AB - Vitamin C-deficient and normal guinea pigs were exposed to various concentrations of NO sub(2) or air, and lavage fluid was obtained and analyzed for protein and lipid content. Exposure of normal animals to 752, 1880, 5640, or 9400 mu g NO sub(2)/m super(3) (0.4, 1.0, 3.0, or 5.0 ppm) for 72 hr did not alter the protein or lipid content of lung lavage fluid. However, exposure of vitamin C-deficient animals to the same concentrations of NO sub(2) caused marked increases in lavage proteins and lipids at all but the 752 mu g/m super(3) (0.4 ppm) level. At 9400 mu g NO sub(2)/m super(3) (5.0 ppm), 50% of the exposed vitamin C-deficient animals died, and pathologic study of the lungs showed proteinaceous edema fluid in the alveoli. Lungs from air-exposed animals and normal animals exposed to NO sub(2) appeared healthy.

AN - 15293729; 123057 AB - Venturi scrubbers are highly efficient in removing submicron dust particles from gas streams. Basically, the gas stream accelerates in the converging section of the venturi to maximum velocity in the throat, where it is sprayed by a scrubbing liquor. The faster velocity of the gas stream atomizes the liquor, and promotes collisions between the particles and the droplets. Agglomeration in the diverging section produces droplets, with entrapped particles, of a size easily removed by mechanical means.

Spectroscopic Properties of Humic Substances. AN - 15293133; 123115 AB - Spectral absorption coefficients and fluorescence quantum efficiencies were determined for humic substances from a variety of sources. Specific absorption coefficients k sub(h), for humic substances at wavelengths lambda from 300 to 500 nm can be closely described by the relation Ae super(B(450- lambda )), where A and B are constants. When the k sub(h) values are in units of liter (mg organic carbon) super(-1)meter super(-1) and wavelength lambda is in nanometers, mean values of A and B for aquatic humus in the 12 water bodies studied were 0.6 plus or minus 0.3 and 0.014 plus or minus 0.001. Results of this study can be used to compute photolysis rates of pollutants as a function of depth in natural waters. JF - Chemosphere AU - Zepp, R G AU - Scholtzhauer, P F AD - Environ. Res.

Palladium (II and IV) and gold (III) were the strongest inhibitors of RNase activity. Other strong inhibitors, in decreasing order of effect, were: sodium dedecyl sulfate, silver (I), EDTA, mercury (II), copper (II), thiram (fungicide), platinum (IV), malathion (pesticide), lead (II), and beryllium (II). Intermediate effects were found with other inorganic cations, many anions, and some other chemicals. A number of compounds of different chemical types caused no measurable effect. None of the chemicals tested caused a measurable activation of this enzyme. JF - Environmental Research AU - Christensen, G M AU - Olson, D L AD - US EPA, Environ. Res.

AN - 15288374; 114858 AB - Duckweed (L. perpusilla ), inhabiting a heavy coal ash, secondary retaining basin from a coal-fired power plant, was the most abundant macrophyte sampled during the summer-fall period of 1979. Lemna in the basin accumulated the most abundant heavy and soft metals (Cd, Cu, Fe, Mn, Zn, Cr, Pb, Ni) affiliated with heavy ash to a greater extent than found in water or coal ash sediment. After a14-day holding period under laboratory conditions of low metal influence, some duckweed metal concentrations declined to levels similar to those found in the ash basin sediments, while other tissue concentrations remained higher. During the 10-day laboratory exposure bioassay after the depuration period, high duckweed mortality was evident within 2 to 10 days at concentrations of 10x and higher. The capacity of duckweed to accumulate potentially toxic heavy metals in coal-ash-retaining systems may have an important role upon the displacement of these elements on a seasonal basis. Aquatic elemental releases of duckweed may be minimal during the growing season due to the bioconcentration capability but can be maximal in the fall during the process of natural mortality and the resulting depuration process into the receiving drainage system.

AN - 15280731; 116750 AB - In 1979 the Environmental Protection Agency (EPA), the Department of Commerce (DOC), the Department of Housing and Urban Development (HUD), and the Department of Transportation (DOT) jointly awarded demonstration grants to eight urban areas to develop and test ways to coordinate economic development and air quality improvement. In the approximately two years since the first grant award, a great deal has been learned about how the needs of communities and industries might best be addressed in working toward local economic and air quality goals. The economic development and air quality problems facing the areas receiving AQTAD grants have been more clearly defined. Improved working relationships have developed among state and local agencies. Changes in the direction and emphasis of some of the activities of the grantees have also occurred. This paper presents interim results of the grants program, focusing on activities that have progressed far enough so that some evaluation of their potential success is possible. Where an urban area has made mid-course changes in grant acticities, a preliminary assessment is made of the reasons for the change. JF - J. AIR POLLUT. CONTR. ASSOC.

AN - 15279969; 111864 AB - Pollutant monitoring studies are being conducted in the Olympic National Park Biosphere Reserve by the U.S. Park Service and the U.S. Environmental Protection Agency. Studies are designed to identify levels of trace element and organic contaminants in physical and biological media. Ten remote sites were selected for intensive sampling. These areas were located in the Hoh, Quinault, and Dosewallips River drainages; at Anderson and Grand Pass; near Ozette Lake and, at the northern edge of Blue Glacier. Their proximity to vehicle-traveled roads varied from 3 to 20 kilometers. Samples were taken in air, water soil, litter and vegetation. Samples will be analyzed for organic and heavy metal contaminants. Airborne particulate size and chemical characterization is being investigated. JF - ENVIRON. MONITOR. AND ASSESS.

AN - 15278447; 111874 AB - Gaseous benzene was rapidly depleted in exposure chambers containing viable soils and plants. When separate components of the system were analyzed, no benzene was detected in soils, plants, or water. Soil microorganisms were shown to be responsible for metabolizing benzene, yielding CO sub(2) as the main product. The rates were sufficiently rapid to suggest that this reaction forms a major pathway for the elimination of benzene from the environment. JF - ENVIRON. MONITOR. AND ASSESS.

The method does not require the use of a computer and eliminates the usual trial and error calculations. An infinite mixing height is assumed. It involves a linear or quadratic solution of the gaussian plume diffusion as a function of the effective stack height and a linear approximation of the Briggs plume rise equation. The linear approximation of the former gives results that are within 5% of the gaussian plume results for stability criteria A, B, and C. For stability criteria D, the difference can be as great as 80%. If a quadratic estimation is used, the differences are less than 3% for stability criteria A, B, and C, and are within 18% for stability criteria D. A linear approximation is used for the Briggs plume rise equation. JF - J. AIR POLLUT. CONTR. ASSOC. AU - Baasel, W D AD - Indust. Environ. Res.

Billions of gallons of water can be recovered for beneficial uses if urban stormwater is properly controlled and treated. The Storm and Combined Sewer Program of the United States Environmental Protection Agency Office of Research and Development has continuously supported the development and demonstration of stormwater control systems and treatment processes. Water quality of the treated storm runoff can meet the required standards for subpotable usage. Current urban stormwater control and treatment technology are discussed, leading to the feasibility of urban stormwater reuse for various purposes in industry, irrigation and recreation. A hypothetical case study illustrating the cost effectiveness of reclaiming urban stormwater for complete industrial supply is presented. JF - J. ENVIRON. ENG. DIV.

We are spending billions of dollars on secondary treatment plants, meanwhile major contributors, such as stormwater and combined sewer overflows, are still uncontrolled. To attain the goals set forth in PL 92-500 and PL 95-217 in an economical and efficient manner, those analyzing, planning, and designing controls must have an understanding of the impact of pollutants on receiving waters. Ties between receiving water quality and stormwater discharges must be clearly established and delineated. Therefore, several years ago, the Storm and Combined Sewer (SCS) Program of the United States Environmental Protection Agency Municipal Environmental Research Laboratory began a modest effort to fill this data void. A brief history of the SCS Program's receiving water impact projects is presented, emphasizing an overview of ongoing and recently completed projects, including significant results. Also, Program needs and areas of anticipated effort are analyzed. JF - J. ENVIRON. ENG. DIV. ASCE AU - Field, R AU - Turkeltaub, R AD - Municipal Environ. Res. Lab.

The ambient gases considered in the chemistry were SO sub(2), NO, NO sub(2), HNO sub(3), O sub(3) and CO sub(2). Raindrops initially at a pH of 5.5 absorbed these gases, and as they fell through a polluted zone, produced SO sub(4) super(2)-a)nd NO sub(3)u- by the oxidation of dissolved SO sub(2) by O sub(3) and the dissociation of HNO sub(3), which reduced the pH. For the chemical mechanism and the below-cloud washout rain events considered, it was observed that: absorption of gaseous HNO sub(3) controlled the acidification in the initial stages of a rain event, and inhibited the production of So sub(4) super(2)- )NO and NO sub(2) played no direct role in the acidification or formation of NO sub(3)u- or SO sub(4) super(2)- )pre-acidified raindrops (pH of 4) were further acidified only by absorbing HNO sub(3).

AN - 15259201; 72901 AB - The recent occurrence of waterborne giardiasis outbreaks has spurred renewed interest in water filtration for cyst removal. Studies with cyst models and Giardia muris cysts suggest that properly operated water filtration plants should be able to remove a high percentage of G. lamblia cysts. For effective cyst removal, diatomaceous earth (DE) filters need 1.0 kg/m super(2) diatomite precoat plus body feed, and granular media filters require coagulation of raw water and production of filtered turbidity well below 1.0 ntu throughout the entire filter run.

Linear correlation coefficients of 0.99,0.96, and 0.96 were observed for the three individual sets of measurements, and a linear correlation coefficient of 0.93 was observed for all measurements. Light attenuation-mass measurements showed similar results when the plant was operating at full and half loads. Particle size measurements were made on four different occasions during the study with similar results.

Risk assessment for the use of materials chosen for RPAR include estimates of worker exposure during various agricultural operations. Observations during earlier field studies in the Columbia Basin Irrigation Project, led us to believe that there was considerable use of captan as a fungicide for seed potatoes. During the spring of 1979 we undertook a study of the potential for exposure to captan of workers involved with various aspects of potato planting.

Awareness of the importance of proper disposal practices came about first as a consequence of the enormous amounts of wastes that are being produced. There has been the realization that the means of disposal of hazardous wastes must be carefully selected to avoid a more serious secondary problem. This paper deals with air pollution problems and potential air pollution problems that were created as a result of disposing of hazardous wastes, the reaction of the affected public and organizations to those problems, and the investigations and corrective measures taken by regulatory agencies to resolve the problems.

Emission rates were calculated for SO sub(2), total sulfate, and particulate matter expressed as g emitted/gal of oil fired. Sulfate emissions amounted to approximately equals 13.4% of the SO sub(x) from the sources. The sulfate emission factor was found to be related to the accumulation of V-containing ash in the boilers resulting in the catalytic oxidation of SO sub(2). Nearly 35,000 boilers of these types are operational in New York City, especially in the winter, to provide heat and hot water. Their elevated sulfate emission rates could play a dominant role in the occurrence of elevated sulfate levels near the metropolitan area during winter episodes. JF - J. AIR POLLUT. CONTR. ASSOC.

Until recently, however, little work has been done on identifying levels of PCBs in the indoor air. This paper describes a method for the analysis of PCBs utilizing low-volume indoor air sampling. The method uses polyurethane foam as a collector and has a limit of detection of similar to 0.01 mu g/m super(3). This study shows that indoor air, whether in commercial, industrial, or residential buildings, contains levels of PCBs at least 1 order of magnitude higher than outdoor levels. Defective fluorescent light ballasts are also shown to emit PCBs and to be an important source of indoor atmospheric contamination. JF - ENVIRON. SCI. & TECH. AU - MacLeod, KE AD - Environ. Toxicol.

Persistence of residues from both formulations spilled as concentrates and as simulated drum rinses were followed for up to 45 months. Spillage of encapsulated formulation resulted in the formulation of a solid cake-like deposit on the soil surface, which could be a particularly attractive hazard to small children. At 45 months, soil residues had decreased by 64% for emulsifiable concentrate spills, and 68% for the soil beneath the microencapsulated cake. Residue in the cake itself only decreased by 31%. Soil residue levels from simulated drum rinses were essentially innocuous by 45 months for the emulsifiable concentrate and by one year for the microencapsulated material. The leaching of methyl parathion from the microencapsulated cake into soil and the relationship between available residue and wet weather were also investigated.

The method provides estimates of the expectation of premature death and the resultant life shortening. Applications to occupational exposure situations are used to demonstrate the technique. Doses ranging from 0.2 to 5.0 rem/yr and over age spans from 10 yr to working lifetimes are investigated. A technique for comparing radiation related mortality with nonradiation related risk of death from on-the-job accidents is introduced. Results show that workers receiving whole body doses equal 5 rem/yr for sustained periods of time incur significant risk of premature death from radiation induced cancer. The risk is estimated, in some cases, to be as high as, or higher than, the average risk of accidental death in high risk industries, depending upon factors such as length of exposure, age at time of exposure, and the radiation risk model used.

Natural sources, such as plant material decay and leaching from coal and oil deposits, also contribute to water pollution by phenolic compounds. The adverse effects of such pollution on aquatic life fall into three general categories: the direct toxicity of the chemicals to aquatic organisms, the lowering of dissolved oxygen in receiving waters, and the imparting of bad taste and odor to the edible flesh of fish and shellfish. The variability of the data on some phenolics makes it difficult to separate toxicity values that vary widely from others because of different test methods rather than different physical properties of the water. Data were lacking on some of the compounds the authors tested, and thus their data contribute significantly to the basic information on these chemicals.

The extraction of the compounds from urine is often incomplete and inconsistent. Several different approaches to the problem are currently being investigated In this work, the ion pair is extracted into dichloromethane which contains the alkylating agent, pentafluorobenzyl bromide. Since the non-polar solvent possesses poor solvating ability, it renders the alkyl phosphate highly reactive toward nucleophilic displacement. The resulting pentafluorobenzyl (PFB) ester derivative is thermally stable and highly responsive under conditions of gas chromatographic analysis using a flame photometric detector or nitrogen-phosphorus detector.

However, this film was found to liberate high concentrations of contaminants such as fluorocarbons, solvents, antioxidants, and manufacturing residues. These contaminants could interfere with both hydrocarbon analyses and smog-chamber reactivity studies. Heat treatment of FEP plastic film at 190 degree C for 24 h minimized film outgassing but did not eliminate it. Less outgassing occurred with 2-mil film than with 5-mil film.

The U.S. EPA's RAM (Urban) model was chosen to estimate 24-hour average sulfur dioxide concentrations in the Cleveland, Ohio area. Point and area source emissions, along with a background concentration were included in the modeling effort. Projections from the model made at the ambient air stations were compared to measured sulfur dioxide concentrations. A total of 3020 comparisons were performed at 33 monitoring sites. An analysis of the results illustrates that, on a daily basis, the predictions of the model did not reflect actual air quality. The correlation coefficients of the 24-hour comparisons at the monitoring sites varied from a low of -0.121 to a high of 0.541. When the highest and second highest modeled concentrations were evaluated with respect to the highest and second highest measured concentrations, over a period of a year, a more favorable comparison was observed.

The two chemical treatments tested were reduction and hydrolysis. Both reactions should result in the elimination of the possibility of cyclic reduction-oxidation with resultant generation of super-oxide radicals, which has been proposed as the primary event responsible for the pulmonary fibrosis caused by paraquat. This pulmonary fibrosis can occur with oral or intra-venous administration or local instillation of paraquat.

Elemental and microscopical analysis of size segregated, ambient particulate and suspended soil samples from the rural southwest indicate that the particles are earth crust material. The composition of the soil related materials changes with changing particle size. Smaller particles tend to vary more in their elemental makeup than corresponding large particles. Numerous thin mineral plates with diameters of several micrometers are aerodynamically sized in the smallest sample size range (<0.5 mu m). Since silicon accounts for one-quarter to one-half the total mass in the fine particle size range, it may be a significant causal factor in regional visibility degradation.

Concerns about the distribution of nitrates between the gas and particle phases, and contributions of HNO sub(3) to acid deposition from the atmosphere have prompted the development of systems to measure HNO sub(3) levels in the atmosphere. Although much attention has been directed towards the collection media and measuring devices, an important source of error may come from those parts of the apparatus which direct sampled air to the collection medium or monitor.

The available evidence on the contribution of natural organics in photochemical pollution is conflicting. Emission measurements suggest that natural organics are emitted in amounts comparable to or even exceeding anthropogenic organics. The contrasting data are aerometric, showing natural sources to be minor in the organic loadings of urban and rural atmospheres. In a position based on the aerometric data in combination with reactivity data, natural organics are judged to contribute negligibly to urban ozone; their contribution to rural O sub(3) is less certain, probably not major.

Four orthogonal factors representing O sub(3) formation potentials were derived using the statistical package SPSS; these factors accounted for over two-thirds of the variations in 1978 summer O sub(3) levels at 21 urban-oriented stations. The analysis confirmed that O sub(3) variations are similar among stations within defined geographical areas; this confirmation supports the widely held theory that ambient O sub(3) formations are regionwide. The analysis suggested that trends analysis for determining general progress in improving O sub(3) air quality should be based on aggregate statistics from clusters of monitors rather than from a single monitoring station within areas associated with the derived factors.

Improvements in the methods of separation and enrichment of the contaminant fraction, initially involving the use of activated carbon as adsorbent, are followed by an account of the replacement of conventional schemes for classifying organic compounds by the various chromatographic techniques applicable to both volatile and non-volatile organics. In place of the boiling point and functional group reactions, the use of retention times and detector responses has given quantitative data on smaller and smaller sample fractions. Several 'landmarks' in the detection and identification of specific pollutants in raw and treated water samples in North America are cited. These include the presence of bis(2-chloroethyl)ether , a proven carcinogen in a public drinking water supply, the discovery of o-nitrochlorobenzene in the Mississippi river, originating from a chemical works at St. Louis , and detectable at a level of 2 ug per litre 1000 miles downstream at New Orleans, and the contribution of a number of petrochemical derivatives to an odour problem in a tributary of the Ohio river and also the Ohio river at Cincinnati.

To combine sensitivity with selectivity the combination of mass spectrometric detection with gas chromatographic separation has been adopted by numerous Environmental Protection Agency laboratories, based on the Finnigan electron impact quadruple mass spectrometer. The manner in which computerized spectral matching and identification procedures have been applied, with reference to a central data file of over 40,000 spectra, is outlined. To speed up the matching process a preliminary search among 1000 reference spectra for compounds previously identified as water pollutants has now been instituted.

In all 72 different volatile compounds were detected, although only 13 were common to all five cities, and thus reflecting differences in the raw water sources. Quantitative analyses were performed on several target compounds inclusive of chloroform and its bromine derivatives. Apart from the THM, only nitrochloromethane was present in amounts greater than 1 ppb, and only for two of the cities. Several other chlorinated organics were present in trace quantities and could be formed as a result of the chlorination process from hydrocarbons and other organic molecules present in the raw water supply.

An experimental community approach was used which incorporated many natural variables while eliminating potential interference by system-induced variables such as thermal/chemical /nutrient additions and mechanical effects found, for example, at a discharge site. Significant chlorination effects were observed on the abundance of eight dominant species and there was a marked decline in total numbers of individuals collected. Only four of the twelve experiments revealed significant differences in short-term community structures and these were related to changes in species dominance and increased in toxicity due to extreme cold weather. The experiments were carried out in South Carolina.

The separated and concentrated cyanide was determined colorimetrically. The method was used to determine hydrogen cyanide in waters and waste waters. The colorimetric reaction between cyanide and pyridine was considered specific, with ammonia, sulphide and phenol resulting in only minor decrease in colour development. Thiocyanate severely affected the determination of cyanide as did silver and nickel. Sulphide removal was also recommended. Vapour-phase equilibration was not regarded as useful as the diffusion procedure for determining low concentrations of hydrogen cyanide.

In contrast to the conventional analytical approach, where the identity of the target compound is known, the requirements of environmental monitoring programmes necessitate a 'broad-spectrum' approach capable of revealing the presence of contaminants not previously suspected of being present. The type of detection system required becomes much more sophisticated, and only mass spectrometry is so far capable of producing a satisfactory response. The twin problems of adapting this detection system for non-volatile compounds and of efficient data reduction and evaluation are discussed in the light of recent developments in the Environmental Protection Agency laboratories.

A detailed description of the fractionation scheme is given together with the methods of separation and identification using glass capillary column chromatography and coupled mass spectrometry. Eighty specific volatile organic compounds were identified and several unknown acids present in relatively high concentrations in raw sewage were presumed to be detergent metabolites. Only a few neutral compounds were identified, the majority consisting of straight or branched chain fatty acids, hydroxy acids, miscellaneous acids and alcohols. The effects of activated sludge treatment and physical-chemical treatment of the raw sewage were compared, as well as the effects of chlorination and ozonolysis. Physical-chemical treatment (inclusive of carbon adsorption) had a more pronounced effect in reducing specific volatile components than activated sludge treatment, but more quantitative information is described. Volatile, methylene chloride-extractable compounds constituted less than 25 per cent of the total organic fraction in raw sewage.

One of the mills was solely dependent on biological treatment with a plastics media biological filter in series with an aerated lagoon, and the other employed a combination of lime coagulation followed by extended biological stabilization (3-6 month retention) in a non-aerated lagoon. The contaminants and their method of extraction and identification are described at length; they were grouped into four main classes, comprising volatile acids, phenolic compounds, long-chain fatty acids and resin acids. Phenols appeared to be the most susceptible to treatment, while the numbers of fatty acids in the waste water from the mill employing the aerated lagoon as a second-stage process actually increased, probably due to the action of the lagoon biota. Details of all the constituents identified and their concentrations at successive points in the treatment chain are tabulated.

The first involves the analysis of drinking water and the raw water source (Ohio river) at Evansville, Ind. , using carbon adsorption techniques for separation of the organics; the second concerned a survey of drinking water samples from four U.S. cities in EPA Region VII, using resin adsorption methods, and the third examined the formation of trihalomethane compounds from water containing added bromide, chloride or iodide ions during the chlorination process. The Evansville investigation revealed the presence of bis(chloropropyl)ether in the treated water supply at 0.3 ug per litre, the source of which was treated to an industrial discharge containing 2760 ug per litre of this compound at a point on the Ohio river 150 miles upstream from the Evansville raw water intake. The drinking water sampled from the four cities in Missouri and Kansas contained detectable amounts (about 0.1 ppb) of several herbicides, presumably due to agricultural runoff into tributary streams, as well as THM formed during the chlorination stage .

Problems arising due to the presence of residual chlorine and a gradual rise in haloform concentration during storage of the sample were overcome by treating the sample with potassium ferrocyanide at alkaline pH. The treated water was then purged with helium after heating to 95C and the volatiles separated on a column of 60/80 mesh Tenax GC packing, for subsequent analysis by gas chromatography coupled with mass spectrometry. The design of the purging apparatus and the provision of specially purified water free of volatile organics, for use as a blank, are also described.

The retention volumes were shown to be positively correlated with the octanol/water partition coefficients when plotted using double logarithmic co-ordinates. In view of the previously established correlation between bioaccumulation factors and octanol/water partition coefficients, it is suggested that the reversed-phase HPLC system may be employed as a screening tool for those compounds in water and effluents most liable to be subject to bioaccumulation in the aquatic environment.

No. 1035) , to govern the effectiveness of zinc compounds as inhibitors of the corrosion of aggressive waters towards asbestos cement (AC) pipes. The Aggressiveness Index for describing the tendency of a water to damage the structure of AC pipes is criticized. A model is developed for the complexation and solubility equilibria of zinc and is extended to show how similar considerations of the aqueous equilibria of other cations and anions may be used to provide more effective prediction of the aggressiveness of a water towards AC pipe in distribution systems. The model has been applied to laboratory pipe-loop coupon tests and field data. A bibliography of 91 references is appended.

The thirteen sites comprised three treatment works in the New Orleans area and ten cities in different parts of U.S.A. selected for the National Organics Reconnaissance Survey. Details of the procedures and typical chromatograms obtained from the gas chromatographic mass spectrometric procedures are included. A total of over 100 compounds were detected, of which 82 contained in XAD-2 resin extracts and 50 in carbon-chloroform extracts prepared from the original samples. Methods for identification of several compounds, chiefly herbicides or insecticides and their derivatives, are described. No polycyclic aromatic hydrocarbons (PAH) or PCB were detected in any of the samples. The identity of one compound present in two of the New Orleans treatment plants and at Cincinnati was confirmed as trimethylisocyanurate, but the origin of this compound is mysterious.

Several types of shipboard incineration systems are compared, with operating temperatures ranging from 820 to 1600C, and their suitability for disposal of waste in different forms and with different physical characteristics is discussed. Existing harbour and terminal facilities in the U.S.A. were reviewed as part of the survey, and those that would accommodate ships similar in length and draught to the conceptual incinerator vessel were identified. The most suitable terminals for such operations were selected on the basis of available cargo handling facilities and management awareness of environmental controls. Recommendations for the further development of such ocean going vessels and support facilities are presented. Some aspects of the disposal system such as the use of single-pass venturi scrubbers with sea water injection, require further evaluation.

The proximity of agricultural or forest land to main streams did not significantly affect stream nutrient levels. It is suggested that sediment intercepted by forested buffer zones will eventually find its way into the stream .

Maximum cell densities in the Little Miami river were attained after 1-2 weeks (except in November) and in the Ohio river after 4 weeks in June and July or 1 week in August and September, while in November the cell density continued to increase as the period of exposure increased. District successional patterns in the composition of the periphyton populations were not observed, the changes with increased exposure time resulting principally from seasonal changes in ambient conditions and phytoplankton populations. The periphyton in both rivers were dominated by diatoms, which averaged 68 per cent of the total cell count. Detailed inventories of species observed are included.

Copper was continuously fed to a small calcareous stream at a concentration of about 120 ug per litre, and changes in the composition of periphytic organisms observed over a ten month period (February-December 1970). Very detailed observations are reported concerning the species composition and abundance of various planktonic organisms in the treated reach and in a control reach of the same stream . Two of the dominant algal species were eliminated from the stream , Cocconeis placentula which formerly contributed from 85 to 98 per cent of summer diatoms, being replaced by three species of diatoms, while several othr species were more abundant in the copper-treated section, including one filamentous blue-green alga and two desmids.

Three alternative approaches are distinguished: namely, measurement of the biological properties of the effluent using captive organisms in the laboratory, similar studies with captive organisms in situ, and an assessment of the biological integrity and community structure of the receiving water body. The relevance of each of these approaches is considered in turn, and published reports concerning accepted methods and case studies are reviewed; while the parameters measured in various situations are summarized in tabular form. More systematic data collection and evaluation is required to take the place of the largely qualitative information on species composition and diversity hitherto recorded.

AN - 13850142; 710365 AB - The authors tested the hypothesis that periodic disturbance such as dredge spoil disposal, could enhance benthic secondary production. Recolonization experiments in estuarine soft-bottom communities in Maryland and Oregon suggest that: Many estuarine softbottom communities do not experience an explosive increase in macrofaunal opportunists or an increase in secondary production after physical disturbance. Species abundant in undisturbed communities may be the dominant early colonizers rather than rare opportunists. Meiofauna may dominate early colonization in some communities.

Calculated results agreed well with data obtained from pipe loop solubility experiments at inorganic carbonate concentration values of 25, 100, and 200 mg per liter as CaCO3. This model increases the predicted minimum molar solubility of lead by factors up to 10,000 over those suggested by 2 previous models which ignored lead carbonate complexes. A general reversal in trend occurs with increasing carbonate concentration, and curve shapes are changed compared with previous models. Results show that there is little advantage to increasing the carbonate level beyond 30-40 mg per liter as CaCO3 in the pH range of 8-9.5. A minimum concentration of carbonate overcomes the higher solubility of lead hydroxide, but an increase in carbonate promotes formation of more soluble lead carbonate complexes. None of the pipe loop tests reduced lead concentration to below the 0.05 mg per liter maximum contaminant level at carbonate concentrations of 0 to 7,950 mg per liter as CaCO3.

The 760 mm diameter filter column contained 1.5 m of No 3 anthracite above 760 mm of No 612 sand on a 460 mm gravel base. CSO treatment at 11 liters per sq m per sec removed suspended solids at an average of 62% across the filter and 66% across the system. BOD removals were 32% and COD removals 40%. Polymer and alum additions improved removals to 38 % for BOD and 50% for COD. Treatment of RDWWW at 5.4 liters per sq m per sec produced suspended solids removals of 67% across the filter and 70% across the system, BOD removals of 33%, and COD removals of 32% across the filter. Addition of polymers improved performance to 39% for BOD and 34% for COD at flow of 8.1 liters per sq m per sec. Use of polymers plus alum did not improve filtration further. Since % removals of suspended solids are dependent on the strength of influent flows, the filtration system should be rated on the basis of total solids captured per unit filter area. This should be at least 15.1 kg per sq m for RDWWW and 22.0 kg per sq m for CSO. Settleable solids were removed to an extent of 95% or greater, but dissolved materials were not removed.

Actions that develop from regulations affect sampling, and conversely, analyses and sampling are used as a basis for setting standards. Procedural problems are illustrated by the example of the dieldrin residue limit for animal feed established by the U.S. EPA. This standard was set by relying on the fish bioaccumulation factor rather than acute and chronic toxicity data, arriving at a value of 0.005 ppb, which is not detectable except by the most refined research techniques. This makes routine sampling and analysis suspect. Suggestions are made for improvements to the National Pollutant Discharge Elimination System reporting system, to make the data received more useful. Testing and analysis problems are illustrated by the cyanide standards hearings held in Illinois, which took 3 years to develop a 0.005 mg per liter standard, a level which requires development of new analytical methods. Two groups within EPA are now working on the ammonia effluent standards, making possible a double set of regulations. Recommended sample preservation procedures are frequently impractical and expensive. However, in the case of phenol sampling, only one general sentence was given as instruction.

However, the magnitude of these changes is expected to be somewhat less than has been experienced in the past decade. Desires will be balanced with realistic goals. Economics will become important in the making of decisions. Attention must be given to the management of the various programs. Decentralization of program administration is recommended. Simplications are needed in the various regulations, with incentives introduced and maintained in the management levels of regulatory programs. Changes will be made in the awarding of construction grants and in the ways in which wastewater facilities are to be operated. Concern will continue in the area of toxic pollutants in the environment, and increased testing will be performed on laboratory animals to determine possible toxic effects on humans. Programs will be developed for controlling nonpoint sources of pollutants. (Baker-FRC) JF - Water and Sewage Works Vol 127, No 10, p 38-40, October, 1980.

A total of 77,678 sites were identified, 10,819 of which the were industrial sites, which were given highest priority in subsequent analyses. The industrial waste sites are estimated to cover about 430,000 acres and receive 50 billion gallons per day of influent. Fewer than 30% are lined, and more than 95% have no regular monitoring. About half the sites contain waste which may have potentially hazardous constituents. Thirty percent overlie usable aquifers and are underlain by zones which allow free movement of escaping wastes. About one third of these sites are within one mile of a water supply well which would be in the path of contaminated water flowing from the site. Similar lack of proper siting, design and monitoring is indicated in the information obtained for municipal, agricultural, mining, and oil and gas brine waste liquids sites. The industrial and municipal sites pose the greatest threat to drinking water resources, while the remainder threaten agricultural groundwater resources. The minimal monitoring of the waste sites results in discovery of contamination only after gross, noticeable environmental changes occur.

To meet these goals, the NMPS defines a process for issuing extensions with enforceable compliance schedules based on grant funding; lays the foundation for the coordination of grant, permit, and enforcement operating practices; and describes enforcement and grant actions as they relate to State Project Lists. These mechanisms contain the following our elements: (1) development of a municipal noncompliance classification process; (2) provision of enforcement/grant procedures for facilities requiring treatment more stringent than secondary; (3) introduction of a municipal referral priority system; and (4) authorization of formulation of a municipal management system to implement NMPS. Despite large Federal municipal grant expenditures, about 65 percent of all major publicly owned treatment works were in noncompliance with municipal pollution abatement regulations as of July 1, 1977. The municipal management system combines a range of compliance, enforcement, and construction grant actions with a system ranking candidate municipalities for judicial action in an attempt to coordinate national compliance efforts.

It is equally clear that while the catalog of available models is quite large, only a few are in common use. Future model use will emphasize applications. New model development will proceed at a slower pace until an adequate data base is available. Receiving water quality models will receive increased use. The use of mini/micro-computers will increase rapidly, and models will be adapted for use with low cost hardware.

Irrigated agriculture and the construction and operation of multi-purpose and hydro-electric power dams have affected water quality. Industrial development has also produced subtle, long-term water quality changes. In the 1940 's and 1950 's a significant problem was a slow rise in the overall temperature regimen. The first major problem affecting users was the development of slimes associated with the sheath bacterium Sphaerotilus which coated fishermen 's nets and lines. State and federal actions, including the Federal Water Pollution Control Act of 1967 helped solve this problem in the early 1970's. In the 1960's, municipal and industrial waste discharges produced unsafe bacteriological levels; however, this is now controlled, as is a condition known as ' dissolved gas supersaturation ' which resulted in losses of 80-90% of downstream migrating salmon. Elevated, almost lethal, water temperatures are still a pervasive problem caused by: (1) dam construction which increases surface area, slows the river flow and produces temperature stratification; (2) point source heat discharges, such as from nuclear power plants; (3) irrigation withdrawals and return flows; and (4) deforestation. To a lesser degree, the water is affected by spills of oil and other hazardous materials. Recent environmental legislation is working toward minimizing these environmental impacts but continued vigilance by the public is also necessary.

Statistics are given on waterborne disease associated with contaminated groundwater. The effect of rainfall patterns on microbiological quality of groundwater supplies is described. A case of Salmonella pollution in the absence of coliform pollution is attributed to lizards in the wells. Petroleum in groundwater is slow to degrade because dissolved oxygen, organic nitrogen, and phosphorus are limited. A study on viruses indicated that a soil pH of 5 or lower resulted in good absorption of viruses. With respect to bioindicators, antibiotic-resistant E. coli proved more suitable as a tracer in monitoring soil water movement than fluorescent dyes. Several studies were done on movement of microorganisms through the soil after application of domestic or farm wastes. Bacteriological aspects of oil and gas drilling were discussed. Methanotrophic bacteria were found associated with oil and gas well water. Bacteriological consequences of using carbohydrate polymers in drilling fluids were discussed.

Rainfall runoff quality data were gathered from 47 catchments in 25 cities and assembled on a storm event basis to study the characteristics of storm runoff and its effects. Indicator bacteria and pathogens were taken from waste water, urban streams and stormwater in another study conducted in Baltimore, Md. Quality of urban runoff was also studied in Burlington, Canada; Northern Guam; Durban, South Africa; Denver, Colorado; the Delaware River; and Berkeley Hills , California. The development of urban hydrology was reviewed in several areas. The understanding of the impact of pollutants on receiving waters was enlarged through several research projects including ones in Knoxville, Tennessee; Lodi, New Jersey; Los Angeles; Newark, Delaware; Hawaii; San Jose, California, and additional sites. Urban stormwater runoff studies using transient flow models were used to study proper management of runoff events. Control of combined sewer overflows was examined from the viewpoint of source controls, collection system controls, and off-line storage and treatment. Studies also dealt with the treatment and disinfection of stormwater runoff and combined sewer overflows.

Also cited is a workshop report on health and legal implications of waste water sludge composting, a history of land treatment of waste water including land application historical perspectives, a discussion of the federal groundwater protection program, and reports of parasites, bacteria, and viruses arising from land application of waste water. The uptake of various organics from sludge applications into crops was investigated, and similar research was conducted regarding inorganic chemical uptake into food crops. The proportion of waste water seeping into the drinking water supplies in the US was investigated, with studies arising concerned with parasites, bacteria, viruses, organics, and inorganic contaminants entering the water supply from this source.

The water sample is maintained with no air space under sealed conditions after collection and during pH measurements. Other precautions are having the buffer and samples at the same temperature, storage of buffers in closed containers, and a constant and not too high stirring rate. The pH of a sample with 3.27 mg per liter of calcium carbonate alkalinity was determined by the suggested method and varied by only + or - 0.002 units over 30 min. When the pH measurements were done with the sample open to the atmosphere, pH increased by 0.8 units over 30 min. This method is not necessary for samples already in equilibrium with the atmosphere or with a very high buffer capacity.

The primary pathways by which radioactivity reaches a dose receptor are: direct external gamma exposure from airborne or groundwater deposited radionuclides; inhalation of radioactive materials; ingestion of radionuclides through contaminated foodstuffs; and ingestion of contaminated water. Congress has provided the Environmental Protection Agency (EPA), Nuclear Regulatory Commission (NRC), and Department of Energy (DOE) with a patchwork of Acts directed at specific processes associated with uranium mining and milling. In many cases, EPA has been ordered to set standards in consultation with NRC and DOE, and the latter two agencies are to implement them. Existing, proposed, or planned regulations will protect the environment from all effluents except groundwater contamination from milling activities. In addition to developing regulations for the uranium fuel cycle, EPA aids NRC Agreement states in their review of impact reports submitted by applicants for milling licenses. NRC solicits EPA review of environmental impact statements that NRC develops for milling projects under its jurisdiction. Future cooperation with the Fish and Wildlife Service may aid EPA efforts to control mining and milling effluents.

Because each public system is different, it is difficult to generalize about the uniform application or removal of ICR systems across the nation. EPA is attempting to gain more flexibility in consideration of the individual circumstances of the grantee and its industrial users. The possibility of an increase in the Gpd flow exemption rate is considered, as it would lessen the administrative burden on certain grantees and would benefit many more small firms that are not able to finance self-treatment facilities. Another possible step would be to exempt grantees demonstrating existing funding mechanisms that provide for future capital expenditures. Exempted grantees would have to show that elimination of ICR would not produce a disproportionate share of current and future treatment system costs being imposed on residential users. Another option is to permit grantees to avoid ICR requirements if industrial capacity financing is not sought from the federal government.

In addition, the Agreements may be an important vehicle for communicating the direction of EPA and State programs to the public. For the 1980 fiscal year, Agreements have been completed in all six Midwestern States. FY 1981 will see Michigan, Indiana and Ohio with Great Lakes SEA issues, and New York may also develop a Great Lakes SEA highlight in connection with a special regulatory assessment, and broad scale intensive survey of the Niagara River in New York. Both the draft Indiana and Ohio SEA 's focus on special problems in nearshore areas of the Great Lakes, estuaries, harbors and beaches which are seriously degraded due to point and nonpoint pollution. In all the State/EPA Agreements, specific tasks are assigned to the State and Federal partners, milestone schedules are established, and funding and responsible party assignments are settled.

In studies of the biotic effects of sediemnts, two broad classes of sedients can be distinguished, organic and inoranic. In first, second, and third order reaches of streams, energy input into the system derives from stream-side vegetation. Coarse Particulate Organic Matter (CPOM) is broken down and fragmented into Fine Particulate Organic Matter (FPOM) which is subsequently transported downstream. The mid-reaches of the stream continuum (fourth through sixth order streams) is the major region of primary productivity, and FPOM is the dominant variety of import material. Further downstream (seventh to twelveth order) th stream energy economy again shifts and becomes heterotrophic, with more turbidity and an increased importance for plankton. The increased turbidity reduced light penetration, the potential for photosynthesis is reduced, and substrate availability for periphyton is reduced. Inorganic sediments are generally assigned on the basis of size and physical method of transport to suspended load or bed load. Suspended loads typically are silts and clays supplied by the watershed. Bed load is composed of larger particles including sand and gravel which are not typically a part of the water column. Biotic impacts of bed load movement are generally attributable to abrasion, scour, and burial. Suspended load increases turbidity, and may interfere with photosynthesis and rspiration.

Problem existing in Region V include: lack of information entered into the STORET data base; possible excess of fixed monitoring stations; use of intersive surveys for single programs rather than multiple purposes; and insufficient monitoring of toxic substances because of lack of resources. The Basic Water Monitoring Program is directed to the protection of the public health through monitoring of toxic and hazardous sources of pollution, and the more traditional pollutants. The components of the program are: ambient monitoring (including toxic monitoring), effluent monitoring, intensive surveys, biological monitoring, quality assurance and STORET.

The test is cheap and simple, but has the disadvantages of possible changes in the toxic substance, due to volatility, degradation, adsorption, or uptake by the organisms. Fish bioassays frequently use fathead minnows as they can be cultured to reduce the variables that would be present in wild fish; channel catfish and blue gills are possible test fish, as are trout if cold water fish are required. Strict quality controls are necessary if the validity of the test is to be assured. Maintenance of a healthy stock of fish, a well-designed laboratory, inert containers for fish, thorough cleaning of containers between tests, acceptable dilution water and dissolved oxygen levels are factors to be considered. A list of the items that should be in the report of the static bioassay is presented.

The units can be arrayed in pairs or series for multiple tests. The apparatus has been used to determine sediment effects in riverine systems and lakes. A river system test was conducted to determine 96 h toxicity of sediments on Hexagenia limbata, Asellus communis, and Daphnia. The toxicities of the sediments were such that it appeared that reduction of a thermal discharge might result in no improvement in the river habitats. The apparatus has also been used to determine toxicity of harbor sediments and provide indications for the disposal of dredged material. If pollution is not severe , the dredged material may be disposed of in the open lake; severely polluted material requires secure land disposal. Useful information is being obtained from the test but refining is needed to improve its replicability.

The achievable goal is to provide test organisms which are healthy, relatively free of pollutants, of known age, physiologically representative of the species, and a culture environment which does not cause stress. Organisms may be reared in the laboratory, obtained from a hatchery, or collected from the wild. This last is the least satisfactory because of the unknown status of the organisms, but with the exception of Daphnia is the only source for invertebrates. The advantages and disadvantages of rearing fish and obtaining them from a hatchery are discussed. Rearing a continuous supply of fish is considered to be most satisfactory, given the initial costs and additional staff for culture maintenance. Recommended freshwater, estuarine , and marine species and test temperatures are listed, as are the prophylatic procedures conducted when fish are obtained from outside sources, and organic contaminants that have been found in fish diets.

The Clean Air Act, the Clean Water Act, the Safe Drinking Water Act, and the Resource Conservation and Recovery Act provide the primary legislative framework for regulations which control these environmental impacts. The EPA administers these laws, and ten of its laboratories conduct or contract oil shale-related environmental studies. The specific objectives of the EPA oil Shale Program are to support the regulatory goals of the agency and to ensure that any oil shale industry to be developed will be accomplished in the most environmentally acceptable manner that is reasonably possible. The document ' Pollution Control Guidance for Oil Shale Development will attempt to capsulize the potential environmental impacts of an oil shale facility /industry. The EPA is not receptive to nor supportive of any plans or incentives which would encourage the rapid development of a large industry because of the environmental uncertainties.

EPA authority for requiring biomonitoring stems from Section 308 of the Clean Water Act, and the states must have similar authority in order to receive NPDES authority. Biomonitoring will be required of major dischargers, especially chemical-based industries, and of minor dischargers if evaluation of the facility, process, and treatment suggest the liklihood of toxic discharges. Major emphasis will be placed on discharges to the Great Lakes and their tributaries. State water quality standards will be used to develop permit limits for toxic substances, but where biomonitoring shows that a substance at levels below the standard is bioaccumulated by organisms or is carcinogenic, teratogenic, or mutagenic, new lower standards will be required. Industries are recommended to begin testing so that they will have information and time to make changes if they are deemed necessary, rather than waiting for enforcement actions.

A previously developed recirculating static model ecosystem was simultaneously used with the flowing water system to test the behavior of pentachloronitrobenzene (PCNB), simazine, and trifluralin. Pesticides were introduced to the static system at ranges of 0.1-100 ppm and at 0.1-100 ppb in the flowing system and the effects were observed on Daphnia magna, Oedogonium cardiacum, Helisoma sp., and Gambusia affinis. The results indicate that both models are valuable tools for determining the fate and behavior of pesticides in the aquatic environment, but cannot be routinely substituted for each other. The static model system simulates a sediment or erosional pesticide source and provides conditions for chemical and biological degradation, while the flowing-water model system simulates an effluent pesticide source and provides continuous chemical exposure to the organisms. Trifluralin which is rapidly degraded was accumulated to a high level in the flowing system, but degraded and so not accumulated in the static system, whereas there was little difference between the systems for the long-lasting pesticides. If the compound is reasonably degradable the flowing system will give the most reliable information, but either system will give good results for the less degradable compounds.

When the National Organics Monitoring Survey showed 10 ppb carbon tetrachloride in drinking water at Huntington, West Virginia, Section 308 inquiries were initiated. Three of the four companies involved cooperated, while the fourth refused self-sampling and analysis. On Feb. 9 Cincinnati tap water contained an exceedingly high level of CCl4, 80 ppb. Additional sample results indicated a 70 ton slug of solvent in the Ohio River. Increased river flow caused EPA computations of the slug 's location to be in error; it had passed the cities several days earlier than expected. Additional spills were reported on Feb. 24 and March 9. Under the emergency provisions of the SDWA and FWPCA, a restraining order was issued to control future discharges. The 70 ton slug and other spills cost government agencies $356,940, and the public undetermined acute and long-term health problems. The EPA has taken measures to limit future discharge of CCl4 into these rivers. The experience of this spill has generated some ideas for preventing future crises: monitoring selected pollutants routinely, formalizing the guidelines for safe levels of various compounds in drinking water, coordinating emergency responses in the hands of one person, mobilizing laboratory facilities and toxicological advice, reviewing NPDES permits, developing a better predictive model for flow in the Ohio and Kanawha Rivers, and implementing a predetermined contingency plan.

In general, point source problems are usually known and addressed with NPDES permits or section 201 municipal construction grants programs, while most of the nonpoint problems are known only in gross terms. A coordinated and integrated approach to point source and nonpoint source related aspects of pollution problems in specific areas is one of the primary features missing from current WQM plans. The lack of coordinated approaches can be remedied by taking all present pollution sources into account when devising geographic priorities for future study and implementation. It is inefficient to attempt to implement structural or nonstructural abatement methods across the countryside regardless of the variable locations and magnitudes of the problems. Five complementary approaches to water quality abatement are: following integrated sub-basin priorities; interagency cooperation; costsharing; regulation; and provision of more direct information and assistance to specific implementing agencies.

New sensing mechanisms and a variety of on-site studies allow a broader and deeper understanding of this phenomenon. On-site treatment system failures may be surface failure and overload flows, groundwater failures or elective failures. Surface failures are usually associated with clogging mat formation, and may be complicated by tight soils or hyudraulic system overload. Groundwater failures are most common on soil of medium to high porosity, and are not usually associated with clogging mat formation. Since the groundwater effluent plume often moves along the surface of the aquifer, its effects are greatly complicated by groundwater flow. Special situation or elective failures include direct tile drainage, straight pipes to streams and midnight pumpout of holding tanks. It also includes the contamination of an entire aquifer by excessive on-site system loading. Nitrates are one of the most significant pollutants in cases of well contamination. Phoshorus has little direct public health impact, but is well known as a major factor in lake and stream enrichment. Bacteria and viruses usually enter bodies of water through overload flow. Failure sensing methods include: interview and inspection; aerial photography, septic leachate detectors, and groundwater flow meters. Using the new sensing approaches it is now possible and cost-effective to determine which of a group of on-site treatment systems may be causing water quality problems, and if an areawide problem exists.

Dredge and fill operations in some waters are subject to section 10 of the 1899 Rivers and Harbors Act supervised by the Army Corps of Engineers, who share supervisory responsiblity for section 404 with the EPA. Section 404 states that consideration must be given to the need for the proposed discharge and the availability of alternative sites and methods of disposal that are less damaging to the environment. Chemical and/or bilogical testing of material proposed for discharge may be required in order to assess the impact of disposal.

Water samples were collected from the Ohio River at Huntington, West Virginia during the period 4 December 1978 through 29 January 1979, and from the Schuylkill River at Philadelphia, Pennsylvania during the period 27 November 1978 through 24 February 1979. The Schuylkill River water contained chloroform ranging from zero to 13.5 ppb. Eleven additional compounds occurred at < 1 ppb values. The Ohio River water contained nine identifiable compounds with all the compounds present below 1 ppb with the exception of chloroform, which ranged from zero to 3 ppb. No non-halogenated compounds were found in either river, with the exception of toluene in one Schuylkill River sample. Among the most prominent compounds found in both rivers were: chloroform, carbon tetrachloride, trichloroethylene, tetrachloroethylene, and 1,1,1-trichloroethane. Cyclical patterns can be seen which indicate some contamination whose source has yet to be determined.

By the year 2000 the market for desalting in the U.S. is expected to be over 29 billion gallons per day. Distillation, freezing, reverse osmosis, and electrodialysis are currently used methods of desalting. Factors influencing the effectiveness of each process include plant location, energy and its availability, feedwater type, and available brine disposal methods. Freezing and distillation are the preferred methods for desalting water with a high salt concentration. Multi-stage flash distillation, which is commonly used, has a continuous cycle to make maximum use of energy but problems occur due to scaling and fouling. Three major steps are involved in desalting by freezing: partial freezing to form an ice-slurry, separation of ice crystals from brine, and melting the ice. Freezing cannot currently desalt large quantities on an economical basis. Electrodialysis uses a cell pair with different types of ion-selective membranes and a direct current to cause ion migration. In reverse osmosis, also a membrane desalting process, pressure is applied to the salt water side of a semipermeable membrane causing fresh water to flow through the membrane. All of the processes generate brine wastes that are disposed of in a variety of ways.

The provisions of the act gave a good indication of the viewpoint many held at the time as to the solutions to our water pollution problems. Those provisions were overwhelmingly oriented towards point-source control. The keystones of the Clean Water Act were The Grants Program for Construction of Municipal Sewage Treatment Facilities under Section 201 and the National Pollutant Discharge Elimination System Permit Program under Section 402. Nonpoint sources were also considered of concern, but certainly not of equal importance. Control of these sources was left to the voluntary use of best management practices to be developed under Section 208 Water Quality Management Plans. Research done in part under Section 208 has shown clearly just how important nonpoint source pollution control was, and stormwater runoff, particularly in urbanzied areas, was found to be one of the most widespread and difficult of the nonpoint sources. The authors suggested that researchers and policy makers need to appeal to the average citizen by educating them about the problems and various solutions related to control of stormwater runoff. Stormwater could be made into a resource that can actually enhance their health, safety, and recreational activities. (See also W90-01919) (Mertz-PTT) JF - Stormwater Management Alternatives.

Ongoing efforts to improve and refine predictive mathematical models impose another need for extensive water quality information. The second successive intensive monitoring program in the Potomac Estuary was performed during the period July to September 1978. This program consisted of three distinct elements: slack tide sampling over a 65 mile reach of the upper estuary; sampling of the effluents at the eight major wastewater treatment plants in the Washington Metropolitan Area; and special field and laboratory studies which addressed specific aspects of the dissolved oxygen budget for mathematical modelling purposes as well as the chronic problem of eutrophication. The 1977 study occurred under low flows whereas the summer of 1978 was characterized by higher and more erratic flows, which were a major driving force in terms of water quality behavior. Comparing the 1977 and 1978 ambient N:P ratio data reveals that their rate of spatial decline, or the tendency for nitrogen to rate limit algal biomass production, appears to be a function of the bloom size as measured by chlorophyll a. Chlorophyll a concentrations in the Potomac during 1978 were low in comparison to 1977 observations and had considerably less variability. In September, blue-green algae comprised approximately 80% of the total population, and 87% of the blue-green population was identified as Pseudanabaena catenata. Blue Plains still constitutes, by far, the largest single point source in the Washington Metropolitan area, accounting for 85% of the BOD5, 77% of the TOC, and 58% of the inorganic PO4.

There were wide variations in chemical compositions, but all contained heavy metals, organic chemicals, and nutrients. Algae, particularly Selenastrum capricornutum (freshwater) and Selenastrum costatum (estuarine), were most responsive to all wastes; some effluents were stimulatory at concentrations of less than 1% but inhibitory at concentrations greater than 50%. Overall, 61% of the effluents were toxic to Daphnia pulex, 40% to fathead minnows (Pimephales promelas), and 53% to grass shrimp (Palaemonetes pugio) and sheepshead minnows (Cyprinodon variegatus). There was no obvious relationship between biological effects and the many parameters of effluent quality. Both growth stimulants and toxicants were present in some wastes. The impact of complex wastes on aquatic systems was calculated using the discharge rate and the LC50, EC50, or SC20. Thus Waste X with low SC20 and high discharge rate was judged most toxic of the group. Waste W, with a low SC20 and low discharge rate, had a low potential for adverse effects.

The history of federal water pollution control legislation is recounted, with emphasis on the October 1977 policy statement, its relationship to the Clean Water Act, and recent construction grants program guidance on land treatment. A November 1974 memorandum put EPA on record as preferring land treatment when cost effective and environmentally acceptable. AT the time of the October 1977 policy statement, EPA issued (with the Corps of Engineers and the Department of Agriculture) the ' Process Design Manual for Land Treatment of Municiapl Waste water'. Recycling, reclamation, and reuse are basic policies outlined in the Clean Water Act of 1977. This act offers incentives to those who choose to implement alternative and innovative technologies, including land use.

It was possible to replace all the makeup water with cooling water blowdown containing up to 690 ppm Na+ (for low-sulfur coal) when operating under appropriate conditions (less than 2500 ppm SO2 in flue gas at a Na+ level of 15,000 ppm in the scrubbing liquor or 3000 ppm SO2 and 8000 ppm Na+). By integrating the water treatment system into the FGD, rather than into the cooling water blowdown stream, water recovery was increased 50% because the FGD scrubber preconcentrates the blowdown prior to water treatment. In addition, the evaporator produces high-quality condensate usable as boiler makeup water.

At present, 73 of the 106 standard metropolitan statistical areas cannot provide secondary treatment for all their flows. The remaining 33 could, but do not consistently provide secondary treatment due to overloading or operation-maintenance problems. Other immediate priorities are innovative and alternative technology and help for small and rural communities. Turning the program over to the states, thus providing local responsibility for operation and maintenance, is also high on the priority list. A prime need is for stability of funding, which will allow orderly planning, prevent program starts and stops, and assure states of money needed to finish projects once they are started.

Also, plans were made to either tap another aquifer or treat and monitor the contaminated aquifer. Since the contaminated levels were not abating and the source remained undetermined, it was decided to use TCE-removal techniques for the existing system. Granular activated carbon (GAC) was excluded due to its high cost. Aeration was used successfully to remove TCE.

This paper shows by simulation analysis that random grab samples are as effective as composite samples for monitoring purposes and provide more information on plant variability. In addition, by using a constant volume compositing regime, a single composite of n subsamples provides as much information as do n grab samples. Monthly average performance measured by M composites is the same as that measured by M random grabs taken over the same period. M grab samples are equally or more informative than the monthly average derived from flow proportional composites. For judging average plant performance, composites are better than grabs; for long term performance, grabs and composites provide the same real information. Process extremes, particularly high values, are more readily revealed by grab samples than by composite samples. This allows earlier corrective measures for out-of-control plant operations and warnings on releases of momentarily high concentrations of toxic or high BOD effluents.

Pipe loop tests were also conducted. Loose asbestos fibers were found in waters with agressiveness indexes up to 10.48, but not over 11. Pipes in systems with agressive water (index under 10) showed visible deterioration, except for one, which was coated with an iron rust-like material. Agressiveness index, pH, alkalinity, and hardness, considered singly, were not sufficient to predict the presence of loose asbestos fibers or pipe deterioration. Metals such as Zn, Fe, and Mn appeared to have a protective effect on pipe walls at the low temperatures common in water distribution systems. Tapping the pipe for water samples liberated fibers into the water supply. Representative samples should be taken in pipe lengths with sufficient flow to cleanse the pipe of debris.

The extent to which indicator bacteria and some viruses are destroyed by anaerobic mesophilic and thermophilic digestion of domestic wastewater sludges as these sludge stabilization processes are currently practiced is also examined. Large variations were found in the numbers of viruses occurring over narrow ranges of numbers of fecal coliforms, total coliforms, and fecal streptococci in raw sludges and in mesophilically and thermophilically digested anaerobic sludges. This finding suggests that the bacteria were poor quantitative reflectors of the numbers of the viruses detected. All three indicator bacteria were destroyed more rapidly than were the viruses by mesophilic and thermophilic digestion of the anaerobic sludges. The relative rates for the destruction of viruses, fecal coliforms, and fecal streptococci in the digested sludges were consistent over the 17 month study. Fecal coliforms were 7 to 8 times more sensitive than the viruses to mesophilic digestion and 9 to 10 times more sensitive to thermophilic digestion. Even more sensitivity was noted among the total coliforms. The rates at which fecal streptococci were destroyed by mesophilic and thermophilic digestion of anaerobic sludges approached those at which the viruses were destroyed by those processes.

Conditioning was to a criterion that required 80% of the fish to leave the 'home' area and reach the 'reward' area within 2 minutes of release. Challenges were at successive 3 C increments above acclimation or the previous challenge temperature. Fish were first observed to delay their entrance into the intervening heated water at challenge temperatures of 12-15 C above acclimation. At each increment above 12-15 C over acclimation temperature, delay in transit increased; however, complete group inhibition was never achieved. Above their critical thermal maximum (CTM) the reward was achieved even at the expense of deaths among the achievers. Responses were the same whether fish were challenged individually or as groups. Fish exposed to their CTM without prior challenges at less stressful temperatures responded similarly to those receiving progressively greater challenges.

In this data base 1,258 compounds appearing in 5,720 observations on 33 water types were tabulated. A total of 175 lists which give the identities and frequencies of occurrence of organic compounds were compiled. Such data constitute the type of information which will be obtained by broad-based monitoring programs. A theoretical model was developed for analyzing the data to provide information applicable to specific compounds. The probability function governing the appearance of a compound on merged lists is identical to the Generalized Geometrical Distribution. According to this calculation, there is only a 14% chance of a specific compound being found in a given list. The maximum number of times a given compound could be expected to appear on several lists is 6. If a given compound appears more frequently than this, it suggests that its absolute rate of occurrence and detection is greater than anticipated. The low frequency of occurrence makes it unlikely that inferential procedures will be developed based on decreased frequencies of observation. The data bases may be analyzed in subsets such as finished drinking waters or specific industrial categories, and relevant estimates may be obtained to guide the collection and interpretation of new data.

The Gramm amendments (HR-4509) would change the burden of proof in setting standards, suspend standards that have been on the books for almost 20 years, reduce measures to limit human exposure to carcinogens, and provide a loop-hole for oil- and gas-exploitation related ejection wells. These amendments are attempts to avoid excessive government regulations and unnecessary increases in utility bills. It was the unequivocal intent of the Congress in the Safe Drinking Water Act to protect the public health. EPA has responded to this intent by controlling trihalomethanes in drinking water to provide public health protection to the vast majority of Americans, who use public water. EPA is also investigating other potential problem chemicals: trichloroethylene, carbon tetrachloride, tetrachloroethylene, 1,1,1-trichloroethane, and 1 ,2-dichloroethane. The issue of protecting public drinking water is more complex than it was a few years ago. Economic impact, cost-benefit analysis, and energy issues must now be considered when implementing the Safe Drinking Water Act.

The health effects of Ba and radionuclides are briefly reviewed. Two-stage coagulation removes about 70% of Ba but is too expensive for practical purposes. Ion exchange and lime precipitation are two effective softening techniques for Ba removal. Powdered and activated carbon are ineffective for Ba removal, while electrodialysis and reverse osmosis show promise for Ba as well as hardness removal. Radium is best removed from drinking water by methods effective for Ca and Ba. The lime and lime-soda ash softening techniques of Ra removal show a pH dependence, with better removal at higher pH. Cation exchange resins will remove many cation radioisotopes, while anion exchange resins will remove anion radioisotopes. The major considerations in selecting a treatment method are the economics , which involve capital and operating costs and depend on the design and size of the facility.

These cost designs were presented as a function of given design parameters. The cost data are intended to be sufficiently accurate for preliminary planning and flexible enough for cost effectiveness studies. The economic impact of meeting these requirements will be site-specific. Implementing the changes may increase the cost of water supply to the individual utilities affected by 20% or more. There is a great deal of controversy over the benefits to be obtained from implementing these standards. Specific costs discussed include costs of alternative disinfectants such as chlorine, ozone, and chlorine dioxide; granular activated carbon costs; design considerations; contact time; and use rate and inflationary effects.

On the state level, a study carried out in North Carolina by the Legislative Commission on Alternatives for Water Management yielded the conclusion that regional water management has many benefits and can be organized in two ways: A state water authority could develop water supplies and provide wholesale supplies to local governments, or a river basin commission could be created in each of the state 's major river basins which would have water management responsibilities and some taxing or revenue-raising powers. Another priority on the state wells is for the legislature to review the future of the Clean Water Bond program, so communities know what funding they might expect. On the federal level, President Carter 's water policy incorporated water conservation regulations and incentives in almost all federal programs that have any impact on water supply or water storage. The current picture on water policy is uncertain because there is a difference of opinion as to the value of grants to local agencies. One view is that local agencies need to be self-sufficient. Another is reflected in the Domenici-Moynihan bill, S.1641, which provides flexibility on the state level and perhaps less red tape in Washington. The paper reviews pending legislation in Congress and possibilities for federal funding of local projects, as well as changing attitudes about various approaches to water management at the federal level.

Ideally, models should integrate the designs of waste water and sludge treatment subsystems, select structure and design from a finite number of discrete alternatives, handle multiple pollutants or waste stream parameters, use principles of mass balance and reaction kinetics in predicting performance, evaluate costs and other systems criteria, and use a computationally efficient solution method. A new computer aided design procedure for waste treatment developed by the EPA is described. The method uses an implicit enumeration approach to select the combination of units that will best meet a set of design criteria from a list of unit process alternatives with fixed design specifications. The effect of return sidestream flows from sludge treatment units is approached by assigning representative penalty values to stream components which may be updated as new system designs are generated. Cost/energy-effectiveness analyses may be accomplished for design problems with over 15,000 alternate system configurations. The model presented is best applied in generating alternative system designs that emphasize different objectives to various degrees.

New analytical procedures have been formulated to meet this mandate, and quality assurance (QA) and quality control (QC) programs have been devised to provide data on the precision and accuracy of the analytical results. QA procedures encompass the total program which ensures the consistency and reliability of results. QC procedures are collective routine actions taken to provide QA in the laboratory. A QA/QC plan was designed for the Organic Chemicals Branch which had placed upon it a 2-wk period for method refinement and a rapid turnaround of samples during a 3-day sampling episode to simulate heavy workload conditions. Spiking and recovery studies were repeatedly employed to overcome the problems of variability in waste waters. The program was composed heavily of QA measures, but the quality of the generated data was known by the end of the study. Changes in the objectives or use of the data would necessitate changes in QA formats. Other programs may not require such QA measures, so before a QA/QC plan is initiated, available resources and projected use of data to be generated should be carefully considered.

The strict liability provisions of section 311(b) (6) of the Federal Water Pollution Control Act, now the Clean Water Act , were upheld in two cases. Certain actions by the Army Corps of Engineers were upheld under section 111 of the 1968 Rivers and Harbors Act, which authorizes the Corps of Engineers to investigate, study and construct projects to prevent or mitigate shore damage attributable to federal navigation works. Citizens for a Better Environment v. Environmental Protection Agency (EPA) involved a challenge to the federal EPA administrator 's approval of Illinois ' program to administer the National Pollutant Discharge Elimination System (NPDES) within the state. The Court found the Illinois scheme deficient in that it failed to provide for adequate citizen participation.

Radioisotopes (99-Tc, 131-I, and 72-Ga) are used in nuclear medicine for the diagnosis and treatment of certain diseases. In laboratories, radioisotopes (3-H, 125-I, 57-Co, 59-Fe, and 14-C) are used for patient diagnosis and in research. Low level radioactive wastes, both solid and liquid, are generated by these uses of nuclear materials and require disposal. In Vermont, at present, the only radioactivity released by sewer discharge to the environment from nuclear medicine activities is that which is contained in patient excreta which are exempt from US Nuclear Regulatory Commission (NRC) controls. All other radioactive wastes from nuclear medicine facilities are disposed of by use of decay storage and/or shipment to one of the nuclear wastes disposal sites. In clinical laboratories, in-vitro procedures are done under authorization of a general NRC license. In some cases, all materials are disposed of by decay storage and/or shipment to one of the nuclear waste disposal sites. In other cases, liquid wastes are dumped into sanitary sewers. An inventory of all radionuclides currently being used by the facilities in VT utilizing sewer discharges was conducted. The amount of each radionuclide being discharged daily from each facility was then determined. Once the radionuclides were discharged, the activity of each radionuclide was reduced if the transit time in the sewer and detention time at the sewage treatment plant exceeds the half-life. It was found that 5 hospitals and 1 college disposed of radioactive waste material into sewer collection and treatment facilities which discharged into streams flowing into Lake Champlain or directly into Lake Champlain itself. In all instances, it was found that the radioactivity of the discharges immediately downstream of the sewage treatment plant did not exceed the US EPA's standards for radioactivity in drinking water.

Under the Toxic Substances Control Act, this information must be provided before new chemicals may be marketed. The subroutines include sedimentation, coagulation-flocculation (2 versions), filtration, aeration (2 versions), chemical oxidation, and granular activated carbon adsorption treatment. The chlorination model needs further experimental data and, in all probability, chemicals will need to be modeled on an individual basis. If the number and distribution of the population at risk and the necessary human and toxicological data are available, the potential health hazards of exposure to a chemical can be assigned. A sample run shows the removal rates for 11 selected chemicals: p-cresol, quinoline, methyl parathion, benzothiophene, 9H-carbazole, benzoquinoline, dibenzothiophene, 7H-dibenzocarbazole, benzoanthracene, benzopyrene, and mirex.

Inspections were conducted in 1974-1979; reports were analyzed from 100 municipalities in Illinois, Indiana, Ohio, and Minnesota, with treatment plants serving from 10,000 to more than 100,000 inhabitants. Daily per capita loadings for flow, BOD, and suspended solids were about 40% higher than values reported in standard engineering texts. Statistical analysis produced the following values (mean of 100 plants): flow, 166 gallons per capita per day; BOD5, 0.203 lb per capita per day; and suspended solids, 0.246 lb per capita per day. Comparable data from the literature were: flow, 58-135 gallons per capita per day; BOD5, 0.1-0.2 lb per capita per day; and suspended solids, 0.08-0.23 lb per capita per day. Increased use of garbage grinders may account for the increase in suspended solids loadings. (Cassar-FRC) JF - Public Works Vol 111, No 1, p 52-53, January, 1980. 3 Fig, 2 Tab, 6 Ref.

Some of the compounds tested are formed by chlorine biocides in cooling waters. Chloroform, bromoform, ethylene bromide, phenol, 4-bromophenol, and 2,4,6-trichlorophenol at concentrations up to 2.0 mg per liter did not affect C14 uptake by phytoplankton. Trichloroethylene stimulated C14 uptake at 0.5 to 1.0 mg per liter. Tetrachloroethylene inhibited uptake slightly at 2.0 mg per liter. C14 uptake expressed as % of control for concentrations of 0.5 to 2.0 mg per liter of other organic compounds were as follows: 2,4,6-tribromoanisole, 81-76%; 4-chlorophenol, 97-94%; 2,4,6-tribromophenol, 96-89%; pentachlorophenol, 39-2%; and pentabromophenol, 4 to -1%. Further tests with the two most toxic compounds, pentabromophenol and pentachlorophenol, at concentrations of 0.125 to 2.0 mg per liter showed that mixed phytoplankton were more sensitive to the chemicals than four individual phytoplankton cultures. Haloamines produced by metering NaOC1 and NH4Cl into the aquaria were more inhibitory than either chemical separately. Chloramine T was not inhibitory to photosynthesis.

Based on experience with evaluating treatment processes, the following five unit treatment processes were used in this investigation: steam- or air-stripping, oil/water separation, filtration on diatomaceous earth or dual media, biochemical oxidation, and activated-carbon adsorption. These suggested potential treatment processes were separately applied to treatment models for each pollutant considered. Steam stripping possibilities are determined by the boiling point of the organic contaminant. Oil-water separation is a good procedure for compounds having relatively low solubilities in water. Separation is achieved by means of API separation or dissolved air flotation. Filtration is used for compounds having low water solubilities and tending to be highly adsorptive on particulate matter, organic or inorganic. Biochemical oxidation can reduce an influent concentration of about 100 mg/liter for phenols to an effluent concentration of 50 micrograms/liter, maximum. Carbon adsorption is particularly effective for compounds of higher molecular weight, lower polarity, increasing hydrocarbon unsaturation, and aromatic structure. Pollutant solubility in water may be associated with entropy, which opposes the driving force for removing the substance from water. This is particularly evident when phenolic and nitrogen-containing compounds are considered. (Baker-FRC) JF - Environmental Science and Technology Vol 14, No 1, p 28-31, January, 1980. 6 Tab.

In the first experiment the recirculating static model ecosystem was used. In the second experiment a continuous dosing system was designed to demonstrate the effect of direct application of trifluralin into the ecosystem. In both experiments organisms were sampled 1, 3, 7, 15, and 30 days after the start of the experiment. In the first experiment the amounts of trifluralin available for accumulation by the organisms depended on the rate of desorption from the soil. In the second, the actual water levels obtained were 0.8, 2.5, and 21.6 ppb in the 1, 10, and 100 ppb treatments , respectively, by day 30. The data indicated extensive variation that can be obtained when using different model ecosystem designs in studying the behavior of pesticides in the aquatic ecosystem. These differences were probably related to the rapid metabolism and degradation of soil-incorporated trifluralin in the first experiment and to the continuous input of trifluralin in the second experiment. A very important difference between the two ecosystems was the toxic effect of trifluralin on the algae and fish during the second experiment. It is concluded that the risks of trifluralin in the aquatic ecosystem are greatest when there is a continuous input of trifluralin. With occasional soil-incorporated input, the degradation processes would minimize the risk.

AN - 15472356; 281047 AB - This study documents the effects of short-term (24 h) sublethal copper exposures on undirected swimming activity and photobehavior of B. improvisus stage II nauplii. All Cu treatments were static, with temperature and salinity conditions at 20 degree C and 15 or 30ppt. The 24 h LC sub(50) estimate for Cu is 88 ppb at 15ppt. and > 200 ppb at 30ppt. Sub-lethal Cu concentrations cause reductions in swimming speed, which decrease progressively with increasing Cu dose. At 50 ppb Cu, this was significant primarily at light intensities below the phototactic threshold. At higher Cu concentrations, significant reductions in mean linear velocity occurred at most light intensities tested. At 30ppt., 50 and 100 ppb Cu also reduce the positive photatactic response and 150 ppb Cu causes reversal of phototaxis at optimal intensities. Swimming speed and photobehavior show promise as sensitive behavioral indicators of copper toxicity. JF - Marine biology.

AN - 15303590; 127028 AB - In stream water quality surveys and in operational studies of sewage treatment plants, long-term biochemical oxygen demand (BOD) tests are often conducted. The purpose of these tests is to find the ultimate oxygen demand of a waste and the first-order rate coefficient for the BOD reaction. This information is mandatory if a water quality model is to be used. This paper presents a technique for finding the least squares estimates for the ultimate BOD and rate coefficient without resorting to complicated computer algorithms or subjective graphical methods.

Cadmium accumulation increased with increased concentration of cadmium in seawater; greater amounts were accumulated during the summer months. Uptake patterns measured as cadmium content were similar among the total soft parts, gill, mantle and visceral mass. A continuous increase of cadmium concentration in the visceral mass was observed. This differed from the uptake patterns observed as cadmium concentration in gill, mantle and total soft parts. Although cadmium accumulation in the total soft parts and the tissus was curvilinear over the entire study period, significant linear relations between cadmium concentration and time indicated a general increasing trend. At seawater temperatures below 6 degree C, when oysters were not actively feeding, cadmium concentrations in the total soft parts varied significantly between treatments, but not within treatments. During spawning, cadmium concentration in the total soft parts increased, whereas the content decreased. JF - MARINE BIOL. AU - Zaroogian, GE AD - Environ. Res.

Jointly sponsored by four federal agencies--the Environmental Protection Agency, and the Departments of Commerce, Housing and Urban Development, and Transportation--the Clean Air Program conducted five regional Clean Air Conferences which brought together representatives from the public and private sectors to discuss air quality problems. The Final Report is a list of recommendations to the federal agencies involved as to how they can better assist cities in meeting the requirements of the Clean Air Act. In short, the recommendations state that better cooperation and communication will be the key ingredients in assisting cities in establishing their clean air programs. Better coordination is needed not only between the federal and local governments but also among the federal agencies themselves. In addition, local governments must be part of the decisionmaking process. Finally, new approaches to resolving clean air problems must be given more attention by federal, state, and local governments. JF - ENVIRON. PROFESS.

At speeds below 35 miles per hour (approximately), traffic noise is dominated by noise generated by the vehicles from mechanical, aerodynamic and combustion process phenomena. It is not until speeds in excess of 35 miles per hour (approximately) are reached that noise due to tire/roadway interaction becomes prominent and dominates the traffic noise spectrum. Since motor vehicle speeds in urban areas typically are less that 35 miles per hour, relief from traffic noise that interferes with human activity most accrue from reduction and/or control of noise created by the vehicles themselves. Studies conducted to identify and characterize motor vehicle noise show that engine exhaust noise dominates the sources of vehicle noise. Accordingly, degradation of exhaust system components, which otherwise muffle engine exhaust noise is the main cause for the escalation of overall vehicle noise. JF - IN "INTER-NOISE 80".

Dieldrin residue levels in environmental substrates, which are indicative of aldrin or dieldrin use, have decreased significantly since the mid-1960s, the peak usage years. However, human tissue studies do not show a corresponding decline in dieldrin residue levels. Thirteen studies, conducted between 1963 and 1976, show that average dieldrin levels in human adipose tissue and human milk fat remain between 0.160 ppm and 0.220 ppm. Other studies suggest that an equilibrium exists in the distribution of dieldrin among various tissues in humans, including blood, fat, brain, and liver. This relationship indicates that the concentration of dieldrin in any tissue may be used as an index of total body burden. JF - PEST. MONITOR. J. AU - Ackerman, L B AD - US EPA, Off.

In reviewing the Agency's actions in this regard, the courts emphasize the importance of reasoned regulatory decisions. The legal requirements to assess risk and provide reasoned decisions in this regard establish the legal importance of testing guidelines and test data, and indicate that should test methodology is as important legally as it is scientifically.

Passive unloading effects are not significant in the long term in areas where mass loading is typically small. A significant seasonal difference in passive loading occurs with a higher percentage of passive loading taking place in the summer. The impact of passive loading can be minimized by reducing the number of days of passive exposure. Additionally, devices are available which can be attached to a hi-vol which effectively eliminate passive loading. JF - J. AIR POLLUT. CONTR. ASSOC.

A total of 20 human subjects were exposed to 100 mu g/m super(3) (0.033 mu M) sulfuric acid aerosol (0.5 mu m mean mass diameter) for 4 hr/day for 2 consecutive days. A total of 17 human subjects were exposed to 4 hr of ambient air on both exposure days. The chemical blood parameters were measured pre- and post- exposure, and 20 hr after the second exposure: serum glutathione, red blood cell glutathione reductase, red blood cell glucose-6-phosphate dehydrogenase, lysozyme, serum glutamic oxaloacetic acid transaminase, serum vitamin E, and 2, 3-diphosphoglycerate. The results indicate no significant response in any of the seven biochemical blood parameters measured. At this level, repeated exposure did not over-burden the upper airway defenses against acid aerosol. JF - ARCHIVES ENVIRON.

The general goal of CEAS is to assess the relative condition of marine coastal systems through the use of the edible blue mussel (Mytilus edulis , Linnaeus) as a biological indicator. The present program has evolved from a number of years of research devoted to assessing the utility of various environmental stress indicators along a known gradient of pollution from the highly stressed Providence River in upper Narragansett Bay, R.I., to the relatively unstressed lower Bay. The resultant CEAS approach utilizes groups of mussels from a single population which are placed in cages along a gradient of pollution. This provides a field research platform upon which laboratory-generated response parameters are being tested and verified. JF - RAPPORTS & PROCES-VERBAUX REUNIONS CONSEIL INT. EXPLOR.

The concentrations of PAHs in drinking water sources range from nanogram to microgram-per-liter quantities. Conventional treatment (flocculation, sedimentation, chlorination, and filtration) appears to substantially reduce total PAH concentrations present at higher concentrations in source waters. A major factor in this reduction is the removal of PAHs adsorbed onto particulate matter. The role of chlorination is not clear and reactions of PAHs with chlorine may in fact produce products which themselves are deleterious. Activated carbon can further assist in PAH removal. However, it may be inappropriate for treatment of PAHs present at low concentrations. Water entering the distribution system can become recontaminated via contact with reservoirs and pipes coated with coal-tar or asphalt based products.

They represented about 8.3% of the total E. coli population. Fifty-five strains, representing each of the 32 resistance patterns identified, were mated with an E. coli K-12 F super(-) strain. Matings were performed on membrane filters, and the cells were washed to remove any colicins produced by the donors. Thirty-one strains, about 5% of the mean E. coli) density in the samples, transferred drug resistance and, hence, possessed conjugative R plasmids. Of these, 80% transferred drug resistance at a frequency of about 10 super(-) super(4) or less. JF - APPL. AND ENVIRON. MICROBIOL.

Sampling was performed with three dichotomous samplers, a mobile laboratory containing instruments to measure gaseous pollutants, and two gas chromatographs for measuring halocarbons. Sulfate and its associated cations represented 61% of the particle mass. Of the total mass measured in the fine particles, elemental carbon accounted for 5% and organic carbon accounted for 10%. Crustal elements such as aluminum, calcium, iron, and silica were minor constituents of the fine-particle mass. During the period of the study the fine-particle aerosol in the Great Smoky Mountains was dominated not by natural organic compounds but by acid sulfates. JF - ENVIRON. SCI. & TECH.

No adverse effects related to barium ingestion were observed in food consumption, clinical signs, body weight, hematologic parameters (i.e., hemoglobin, hematocrit, red cell count, leukocyte count, prothrombin time, and fibrinogen), serum enzyme activities, serum ions, gross pathology, and histopathology. Water consumption was slightly depressed in the highest dose group. A slight decrease in the relative weight of adrenals of treated vs. control animals was observed. Increasing dose, but not duration of exposure, produced related increases in barium concentrations in liver, skeletal muscle, heart, and bone, with the highest concentrations observed in bone.

Because of recent evidence outlining the role in pulmonary immune development of particle size and depth of mycoplasma deposition in the hamster lung, the authors developed an aerosol chamber for the reproducible aerosolization of radiolabeled M. pneumoniae .

This procedure and analogous procedures for non-lognormal concentrations implicitly assume that sequences of pollutant concentrations are stationary. However, air pollutant concentrations are nonstationary. In this paper it is shown that application of procedures, such as Larsen's that assume stationarity to a nonstationary sequence of concentrations can produce seriously erroneous results. Two methods for using air quality data to estimate the distributional properties of maxima of nonstationary sequences of concentrations are illustrated.

These discrepancies are much reduced when one considers the atmospheric photo-oxidation of the non-methane organic material released by vegetation. From known oxidation mechanisms it has been inferred that these photo-oxidations might be the largest single source of atmospheric carbon monoxide.

Estimates of the total number of compounds which might be identifiable by gas chromatograhpy-mass spectrometry, have been made. The theoretical findings have been translated into practice by the development of a multichannel sampler (Tigwell and Schaeffer 1980) which permits the simultaneous collection of a sample by up to four methods. The present paper will describe how these elements interplayed in a study of a coke plant's waste water.

Forty-eight female rats were given one of four lead chloride drinking water solutions: 0.05, 0.58, 17, or 352 ppm lead. Two animals from each group were sacrificed after 3, 6, 9, 12, 15, and 24 weeks of treatment. Both femurs and the frontal and parietal bones of the skull were removed from each animal and analyzed for lead concentration. A significant accumulation of lead was observed in femurs and skull bones only from animals in the 352 ppm lead treatment group. The lead concentrations of the femurs were significantly higher than skull lead concentrations for all groups.

The system covers the infrared spectral region from 650 to 6000 cm super(-1) at a maximum resolution of 0.06 cm super(-1). In the absorption mode, many gaseous pollutants can be detected at parts per billion levels over a one kilometer path. In the emission mode, warm gases exiting industrial stacks can be detected at parts per million levels. The temperature of the stack gases can be determined directly from the spectra. This paper describes the interferometer system and results of recent measurements of jet engine, brick kiln, gypsum pond, and industrial stack emissions. JF - OPT. ENG.

Overall, endrin was more toxic than methoxychlor. Asellus was the most sensitive to methoxychlor; methoxychlor had little effect on Hydropsyche during week 1, but during weeks 2-4 the LC50 decreased from 2.90 to 1.30 ug per litre; no stoneflies or snails died during exposure to methoxychlor, but overactivity in the former species occurred. The LC50 for methoxychlor at 28 days ranged from 0.42 to 4.23 ug per litre. The snail accumulated 13-25 times more methoxychlor than the stonefly, and 5000-8700 times more methoxychlor than the water concentration. The caddisfly was the most sensitive to endrin; the LC50 at 4 days was 0.34 ug per litre and then fell, with survivors only at 0.03 ug per litre.

This study was to determine the short-term lethal concentration and long-term effect of waste oil on the survival, growth and reproduction of the American flagfish, Jordanella floridae. The results are given in great detail, showing the maximum acceptable toxicant concentration for the water-soluble fraction of used crankcase oil was estimated to fall between 325 and 930 u litres per litre. It is speculated that heavy metals probably contribute significantly to the toxicity of the waste oil tested.

The results so far are inconclusive, however, chlorine dioxide may present a greater hazard than the other disinfectants, but the removal of precursor organic material may make the generation of carcinogenic by-products less important. Indications of hazards due to the sensitivity of the U.S. population to agents producing haemolytic anaemia are discussed.

To obtain clearly resolved peaks on a gas chromatogram of individual organic compounds, present in trace amounts, the extract was partitioned into acid, methylated acid and base/neutral fractions and the latter fraction was further partitioned on a silica gel microcolumn by elution with solvents of different polarities. The fractions were analysed on a computerized GC/MS system, equipped with glass capillary columns. Some 460 organic compounds were identified, including 41 polynuclear aromatic compounds and 15 PCB.

For samples which are not in equilibrium with the atmosphere it is recommended that they be kept under sealed conditions after collection and during pH measurement to eliminate meter drift caused by interaction with atmospheric carbon dioxide. While this procedure is not necessary in cases where equilibrium with the atmosphere is reached or there is a high buffer capacity it is suggested that it be used in all cases where drifting problems occur, to avoid equilibrium checks.

The LC50 values for the metals were, respectively, 16.3, 3.8, 36.8 and 258 ug per litre. Copper levels over 28 ug per litre and cadmium levels as low as 8 ug per litre resulted in 100 per cent larval deaths. At 80-100 ug per litre, zinc effected a 90 per cent mortality. At concentrations less than the LC50, no growth inhibition occurred. The LC50 values for Cu, Pb and Zn were up to 870, 250 and 1600 times lower, respectively, than those previously reported. The reasons are discussed, including susceptibility at particular life-cycle stages and species susceptibility.

The research reported is in four sections: field evaluation of 10 public water supply systems, pilot-scale tests under controlled conditions, bench-scale tests, and in situ rehabilitation of deteriorated pipe. It is found that asbestos cement pipe behaves much like any other piping materials except PVC, in that if aggressive water conditions exist the pipe will deteriorate and high fibre counts are likely; if the water is not corrosive, no deterioration problems arise.

It gives relative toxicities or stimulatory effects on algae and, in conjunction with toxicity tests, can be used to estimate potential effects of pollutants on aquatic systems. Algae are grown in optically matched culture tubes that fit directly into a spectrophotometer, allowing population density to be estimated by absorbance without removing the samples. At the end of the test, cell counts are made and toxicity expressed with regard to biomass and cell numbers.

A study of the size distribution of asbestos fibres indicates that the fibres produced by corrosion of asbestos cement pipe are generally longer than those produced by other means . Wastes discharged from the processing of iron ore, have contributed large numbers of amphibole fibres to parts of lake Superior supplying raw water to adjacent cities. Concentrations of chrysotile fibres of 100 million fibres per litre and over have also been recorded in piped water supplies from a number of U.S. cities, but the majority of consumers are not exposed to concentrations greater than 1 million fibres per litre. Susceptibility of asbestos cement pipes to corrosion can be predicted using the aggressiveness index which takes into account the pH, total alkalinity and calcium hardness of the water. Acid rain falling on asbestos roofs may also cause appreciable fibre concentrations in water collected in cisterns and used for domestic purposes in areas without piped water supplies.

Both gas and mechanical mixing systems were compared at MSW/MSS ratios of 9:1 and 3:1. Gas mixing was generally inadequate and resulted in a high build-up of volatile solids near the surface of the liquor.

In vivo experiments were carried out on 8- to 10-day old larvae in seawater dosed with bromodeoxyuridine and the mutagen mitomycin C(MMC). Since the species has 18 large chromosomes, is easily cultured, is a benthic species and forms part of the food web for commercially important fishes, it may be a useful model for studying the effects of genetic toxicants in marine environments. Certain difficulties with the assay, are pointed out.

The particular role of micro-organisms in these transformations is considered as it affects the persistence of chemicals in the environment. The general philosophy of the U.S. regulatory authorities in their evaluation of these effects is reviewed, and some areas of particular uncertainty are examined, such as the correct choice of inocula, media and substrate concentration in order to achieve results which truly reflect those in the real environment. Certain types of micro-organism are also viewed as essential to the decomposition of commonly occurring waste products, releasing vital nutrients in the process, and the protection of such microflora against harmful effects is therefore of major importance. Test methods should therefore include procedures for assessing the response of such organisms to synthetic chemicals. JF - Aquatic Microbial Ecology (edited by Colwell.

The reaction between monochloramine and the bromide ion was shown to follow first-order kinetics with respect to monochloramine, the bromide ion and hydrogen ion concentration over the pH range 6.8 to 8.2. The oxidation of bromide was considered to be the primary pathway for monochloramine removal in highly saline waters. A mixed haloamine, bromochloramine, was the main reaction product of the reaction between monochloramine and the bromide ion. The decomposition of monochloramine in marine waters may produce a less toxic discharge since bromochloramine is chemically less stable than monochloramine. The disappearance of monochloramine in highly saline waters (33.6 per thou) follows the rate of bromide oxidation by monochloramine.

The importance of iron in these systems and the fact that the arsenite ion is about 60 times more toxic to humans than arsenate, are emphasized.

Among the measures being undertaken, in U.S.A. to counteract pollution due to urban run-off are an urban storm water pollution control study in Florida, a receiving water quality model for urban storm-water management, the development of a general methodology for evaluating the impact of combined sewer overflow and a project at Manhattan College to develop a methodology for defining criteria for wet weather water quality standards. A manual for wet weather flow quality and quantity monitoring is in production.

Successful incineration depends on proper mixing of combustion gases, fuel mixture and volatile solids in the sludge. Two types of furnace are generally used for sludge incineration, namely multiple-hearth and fluidized bed. These are described in detail and their performance is discussed. It is concluded that new solutions for the control of air pollution must be found if incineration is to be a viable alternative for the disposal of sludge. There may be a two-stage system where the main incinerator is operated at the lowest possible temperature and the second stage operates at very high temperatures. These would be followed by air pollution control equipment.

The acetylcholinesterase activity of the isolated nerve cord after in vivo exposure was depressed by methyl parathion only in the moribund shrimp after exposure for 6 hours at 1.3 ug per litre. Methyl paraoxon did not depress the enzymatic activity in surviving shrimp after exposure for 74 hours to 0.98 ug per litre. In vitro, exposure of the excised ventral nerve cord resulted in complete inhibition after exposure for 1 hour to 60 mg per litre methyl parathion, or 300 ug per litre methyl paraoxon. Acetylcholinesterase versus death was considered not to constitute a direct relationship in shrimp, and the degree of enzyme inhibition in the ventral nerve cord of shrimp captured from neutral waters is not a reliable or accurate predictor of levels of water pollution.

The feasibility of using cooling tower blowdown in place of clean water as make-up for the scrubbers was established and the additional benefits of vapour compression evaporators in the recirculating system were also evaluated. When the flue gas scrubber is allowed to function as an evaporator preconcentrating blowdown prior to its introduction to a vapour compression evaporator, a 50 per cent increase in the quantity of water recovered can be achieved, while producing sufficient high-quality condensate to meet the demands for boiler make-up water.

The 96-hour LC50 was 2.06 ug per litre and a 28-day exposure to an estimated concentration of only 0.075 ug per litre decreased the production of offspring from females. Data from chronic exposure test also indicated not only reproductive impairment in the parents but also in the progeny, an effect which persisted after a recovery period in water containing no dimilin.

The immediate survey is followed by regular monitoring at prescribed intervals to evaluate chronic effects. The scope of the method and its application in practice are described with reference to the Peck Slip oil spill off the northeast coast of Puerto Rico and the attendant pollution of mangrove forests along the coast. In addition the concept of a vulnerability index is developed as an aid to pre-spill contingency planning and some examples of its application are given, especially in the Cook Inlet portion of the southern Alaskan coastline.

Each ecosystem consisted of 10 parallel sand-filled compartments supplied from a constant-head reservoir with provision for continuous injection of the test substance. Tests were conducted using several chlorinated organic compounds, as well as barite and a lignosulphonate drilling mud, and their effects were assessed by comparison of the numbers, species and phyla of benthic organisms present at the end of the tests. The effects observed were broadly consistent with the results of single-species tests, but the method is claimed to possess several advantages in allowing the effects on community structure, on species not normally tested and on changes in sediment structure, to be predicted more accurately.

Electron micrographs revealed hard but porous surfaces, a multitude of crystal arrays below the surface and evidence of micro-organisms predominantly at or near the surface. These included diatoms, algae, actinomycetes, elongated bacteria and, possibly, flagellate cells . The ability of micro-organisms to colonize within the surface veneer of the encrustations was demonstrated. The magnitude of the bacterial colonization revealed is higher than that previously surmised. Some remedies are suggested.

Health hazards to which sewage works personnel are occupationally exposed are reviewed, and the toxic effects associated with the inhalation of vapours and allergies caused by inhalation of dust from dried sludge are considered. Toxic responses to hydrogen sulphide, carbon dioxide, methane and solvents are discussed, and the threshold limit values for continuous exposure to these gases are compared with the concentrations sometimes encountered in unventilated areas following contamination with or anaerobic decomposition of sewage constituents.

The extended data have been used to derive a mathematical model for assessing the fate and transport of five common phthalate esters in simulated aquatic environments. It is shown that hydrolysis, biolysis, photolysis, volatilization and export can, under certain environmental conditions and ester properties, be competing processes. It is indicated that the higher molecular weight esters will tend not to undergo transformation. Export from the ecosystem appears to be the dominant process.

The results demonstrated enhanced susceptibility to infection in fish exposed to copper at 4.5 pp 1000 mil., and cadmium at 1.0 pp 1000 mil., while zinc, even at 99 pp 1000 mil., caused a suppression of the infection. Since the limit of 4.5 pp 1000 mil., for copper is well below the level normally associated with toxic response, further consideration of maximum acceptable toxicant levels for this metal may be desirable in view of the possibility that fish surviving an initial toxicant exposure may easily succumb to pathogenic micro-organisms.

The microphotographs obtained showed definite evidence of weathering and exposure of asbestos fibres to abrasion and release in contact with water, both under field conditions and during laboratory tests. Energy dispersive X-ray analysis spectra also revealed that the surface could be chemically altered during contact with water, with release of asbestos fibres, although certain inhibitors (such as zinc chloride) when added to the water appeared to minimize this type of attack.

In addition, highly aggressive water flowing though asbestos-cement pipes can cause asbestos fibres to be released into the water. Analyses of drinking water samples from public utilities in areas randomly selected throughout the U.S.A. is reported. The results indicate that 16-18 per cent of the utilities have highly aggressive water that could be very corrosive. The computation of an aggressiveness index is explained and shown to be simpler than the Langelier saturation index. The Ryznar stability index, which gives a quantitative index of the amount of calcium carbonate scale that would be formed, is also outlined.

The occurrence of the pathogens in animals, as a potential source of infection is considered, supported by a 4 page table listing the reported findings for enteropathogenic strains of E. coli and various Salmonella serotypes and shorter tables giving the occurrence of Salmonella and Enteriobacteria in cold blooded animals, and Leptospira in animals. Worldwide a wide range of pathogenic organisms have been reported to occur, and methods and media employed for detection and isolation are discussed. Of recent concern in the Western hemisphere is the presence of the bacterium, Legionella pneumophila, the causative organism of Legionnaires disease, which was isolated from air conditioning cooling systems and also from non-epidemic related natural habitats in Georgia and South Carolina.

Statistics relating to such outbreaks in the U.S.A. are presented, indicating that the most commonly occurring form was giardiasis, due to transmission of Giardia lamblia; however in at least two major outbreaks of gastroenteritis (in 1975-76) the causative organism could not be identified. Guidelines for the investigation of such outbreaks have been published with a view to increasing the chances of isolation of the responsible organism. Other diseases are surveyed in turn, consisting of amoebiosis, cholera, hepatitis A, yersiniosis, viral gastroenteritis, and a few miscellaneous infections, including diarrhoea in members of a polar expedition who drank water from an Antarctic lake from which Klebsiella was later isolated.

A handbook of best management practices, entitled Stormwater Management Procedures and Methods has been published, and extensive use of the SWMM and STORM models has been made in Canada and the U.S.A. in order to calculate the quantity and discharge/time characteristics of stormwater flows. Other models including the effects of quality are also discussed for use where stormwater is discharged direct to a watercourse; examples are SWOPS, SWOHS, QQS and HLOAD. The impact of U.S. legislation (PL 92-500 and 95-217) on the design of stormwater overflows has been studied and estimates of the capital cost of compliance have been reported for numerous locations. The effects of trace metals on the composition of runoff and sediments have been assessed for catchments of different types, and the use of computer systems for correlating land use with peak discharge fluctuations is also considered. Possibilities of in-situ and separate treatment for stormwater flows are discussed, together with the effects of infiltration into sanitary sewer systems. References total 150.

The incidence of certain sewage related or waterborne diseases has been surveyed on the basis of epidemiological data, and comparisons between control and irrigated zones have been reported. A comprehensive report from a workshop on the legal and health implications of sewage sludge has appeared, indicating that the risks were low enough to permit further development and operation of municipal composting systems. The potential hazards of land application are also reviewed from the standpoint of pathogen survival (bacteria, viruses and parasites), trace organic contaminants, and inorganics, including heavy metals, especially cadmium accumulation. The indirect reuse of sewage effluent in water abstracted for potable supplies is also considered in the light of studies in the U.S.A., and the evidence for mutagenic and possible carcinogenic effects of concentrates obtained by reverse osmosis.

The microbial ecology of water is discussed, with reference to the environmental factors favouring the survival and multiplication of particular species, and reports of field studies of the nature and distribution of microoganisms along the course of certain rivers from the source to the tidal region are reviewed, while a separate section considers the microbiology of lakes and impoundments, including those used for recreational purposes. The occurrence of faecal microorganisms is considered in the light of the natural bird populations, especially wildfowl; and effects of human activities.

In one case, improved laboratory methodology resulted in the repeated isolation of Yersinia enterocolitica in chlorinated supplies which were reportedly free of total and faecal coliforms and enterococci. Other surveys, in semi-tropical areas, have found from 45-80 per cent of household tapwater samples failing the coliform criterion. Studies of the microbial populations developing in granular activated carbon filters installed for removal of trace organics have been reported, and comparative studies performed on alternative disinfection systems for small community systems. Problems of contamination following repair or replacement of components in the distribution system have also been discussed. Surveys of swimming pool waters indicated that a free chlorine concentration of 0.8 mg per litre was necessary; ozonation did not reduce chlorine requirements but did improve the aesthetic conditions.

Temperature-depth profiles in a nonpumping well are used to determine vertical groundwater velocities of the downward leakage of water recharging the aquifer which is overlain by semiconfining beds of clay-rich glacial drift. Calculated and observed depths of penetration (19 m) of the annual surface temperature wave, and demonstration of the thermal stability of the well, validate application of the theory, which uses a dimensionless parameter beta to relate curvature in temperature-depth profiles to the magnitude of vertical leakage. Generally, the magnitude of beta decreases as the depth interval L within the aquitard increases. The corresponding decrease in the vertical component of groundwater velocity accompanies a gradual coarsening with depth of the aquitard materials. Temperature differences over time at a given depth within a thermally stable well are found to be within the accuracy of the temperature measuring system. Analysis of variations in beta over time shows that the variability can be due to the limitations of the resolution (0.01C) of the temperature measuring system. Recharge rates determined by analysis of temperature-depth profiles range from 2.47 x 10 to the minus 9th power to 9.86 x 10 to the minus 9th power m/s and agree with estimates resulting from water-budget method.

The scientific basis for treating and the reuse/recycling of wastewater should give greater emphasis to ecology and the management of natural biological systems. Neither the technological problems of designing biological systems nor the political and institutional constraints facing their implementation should prevent the increased future use of aquaculture systems for wastewater treatment. Where these systems can be made to work they should offer effective solutions to the need for cost-effective, environmentally acceptable, and energy efficient wastewater treatment and recycle/reuse practices. In order to assist in encouraging greater use of these aquaculture systems for wastewater treatment, we need to make sure that the results of past and ongoing research efforts are effectively applied to innovative/alternative technology projects funded through the EPA Construction Grants Program.

Water conservation is defined in many ways such as wise water management or saving water at one place and time to make it available for more beneficial uses. In the past, Federal programs have often been too late, scattered, and uncoordinated. To change this the President has required that all Federal water programs be reassessed, reviewed, and examined for water conservation opportunities. Nineteen Task Forces are conducting this coordinated analysis of Federal programs and water policy. A Water Policy Coordination Group keeps the Task Forces on schedule and on track. Task Force 6A has compiled a preliminary report of information and recommendations from 87 Federal prograns. A matrix was developed to rank the recommendations for the 87 programs. Reclamation rehabilitation was ranked number 1, waste treatment management was ranked number 3, and water resources research was ranked number 14. This effort begun by Task Force 6A must be continued and expanded if water management is to make full use of Federal programs.

The central thesis is that utility managers must look at elements other than capital facilities costs in attempting to minimize the overall cost of water supply. The system operating costs of both areas increased dramatically over the 1965-1974 study period, with Fairfax County increasing its OM cost as a percentage of total cost from 65 to 70%, and San Diego 's increasing from 74 to 87%. Equations are presented which show that, over time, a utility 's operating costs represent an increasingly larger share of its budget. Support services are the most rapidly increasing portion of operating costs, with labor cost increases being somewhat less significant. A regression equation relates cost to labor wages and indicates that annual operating cost increases almost linearly with respect to increases in revenue-producing water, if labor wage rates remain constant. Conclusions indicate that operating cost elements, particularly labor productivity, have been ignored in considering a utility 's budget. Thus, utility managers are advised to think in terms of balanced capital investment designed to minimize total costs and not simply to minimize capital investment alone.

Environments and ecosystems have sustained large alterations, leading to reduced productivity and loss of prime fish and wildlife habitat. The Clean Water Act of 1977 Guidelines mandate the examination of practical alternatives to the discharge of dredged or fill material. A general evaluation determines the possibility of a chemically polluted sediment. ' Guidelines to Minimize Impacts ' are incorporated concerning the substrate, water quality, tidal fluctuations, currents, salinity and other characteristics. Particular attention must be given to minimize construction impacts to special aquatic sites, such as sanctuaries, refuges, wetlands, vegetated shallows and coral reefs. Based on the Factual Determinations which are made, the Corps of Engineers must decide if the proposed action is in compliance with the S404 Guidelines, and thus whether or not to issue the permit.

This statement is equally applicable to aquatic resources, which is basically why no economic value has been fixed for aquatic resources. Consequently, no amount of public compensation funding under current law is guaranteed to go to those in fact injured by water pollution until the valuation problem has been resolved. The existing body of law regarding damage assessment are examined, including the common law approach and several state legislative schemes. The probable consequences of implementing a natural resource assessment scheme based on established natural resource damage assessment procedures and valuation tables are explored. Special attention is paid to the case of Commonwealth of Puerto Rico v. SS Zoe Colocotroni and Senate bill 2083, the 1978 Oil Pollution Liability and Compensation Act, which would establish a strict liability scheme.

In several states, the planning is being performed entirely by area-wide agencies. To date, $225 million in Federal funds has been obligated for this program, and another $75 million is available in EPA Regional Offices for obligation. Of the 225 planning efforts that have been initiated, 114 are in or through the process of local government adoptions; 21 of these plans have been certified by the State; and two have been approved by EPA. From an EPA standpoint, the desire was to secure a long-term funding commitment from the Office of Management and Budget (OMB) for the program, and to increase the FY 1978 budget request. A total Federal cost of the program was projected as being $542 million for the period between fiscal years 1978 and 1983. These funds would cover activities under four major categories: facilities planning for municipal treatment works, urban stormwater runoff, pretreatment, and nonpoint sources. The greatest portion of funds would be used for nonpoint sources, followed by urban stormwater runoff. Significant changes have been made in revised regulations including procedures covering changes in designation of agencies. Regulations also cover the major transition that will occur in the 208 program over the next several years. EPA is also imposing a funding sanction beginning in fiscal year 1980--no planning agency, state or areawide, can receive any additional planning funds unless a portion of a previously approved 208 plan is being implemented. The regulations also require timely action by the states on the certification of plans, especially areawide plans. (See also W90-04338)(Lantz-PTT) JF - Water Problems of Urbanizing Areas.

It was found that the waste stream samples were not miscible in a simple acetic acid leach solution. The samples lumped, and all the samples formed globules, which sank or floated in the solution, depending on their density. The results of the analysis of the filtrate revealed heavy metal concentrations of less than 0.01 ppm. Chloroform was used in a test procedure designed to simulate codisposal of waste with municipal refuse. The addition of the chloroform to the sample solution caused the waste globules to break down. If allowed to settle, two layers formed, acetic acid solution and chloroform, waste layers. When mixed, the two layers blend, and better contact between the waste and the acetic acid solution is achieved. It can be seen from these results that the heavy metals were leached to the acid solution when chloroform was added. The values for crude oil and oil shale are relatively low , since the total metals in the sample were low. In the cases of organic paint sludge and cutting oil wastes, large amounts of leachable lead (386 and 1310 mg/L) were identified by using the chloroform procedure. Other waste samples, which were found to be nonmiscible in the acetic acid solution, were tested to determine the effect of chloroform on miscibility. While heavy metal analysis was not done, the miscibility was improved in every case. It should be noted that the chloroform layer can be readily used after leaching is completed to identify the presence of halogenated hydrocarbons and other organics in the waste.

Two competing membrane types are the asymmetric cellulose acetate membrane, the first type developed and used today in most existing reverse osmosis plants; and the composite membrane which has become available in the early 1970s. The composite membrane has superior salt rejection capabilities, but is less able to withstand residual chlorine. The new research direction is in finding a chlorine-resistant composite membrane. The Yuma plant will remove about 90% of the salt from brackish water, and the desalted effluent will be blended with untreated drainage water and discharged into the Colorado River. The Jedda plant, the world 's largest membrane plant, became operational in 1978 and passed acceptance in 1979.

The 208 programs may provide the states with the means to involve the public in planning and determining practical solutions to ground water pollution problems. Needs and obstacles in establishing a 208 program for groundwater planning in Illinois are discussed. The present approach of remedial action for major cases of pollution provides a reasonable degree of protection in terms of control, but there is not a high degree of planning for the management of future ground water quality and quantity in Illinois. The 208 approach addresses three new requirements for plans prepared with Federal funding: (1) plans must have continual public involvement, (2) alternatives must include the definition of mechanisms for implementation, and (3) plans must be updated annually to reflect the results of each year 's progress. Planning programs under 208 are usually regional in scope rather than site-specific. The preparation of a ' 5-Year Strategy ' for each State under the Water Quality Management Planning programs, public involvement, and the USEPA 's new emphasis on aquifer protection as a priority issue will provide the mechanism for funding ground water planning under 208 programs.

The Act was amended in November 1977 to prohibit the dumping of harmful sewage sludge in the ocean after December 31, 1981. Scientific investigations, mainly by NOAA, have documented several adverse environmental impacts at the sludge and dredged material sites. These impacts include elevated concentration of heavy metals, organic matter, and bacterial in the water and bottom sediments with attendant threat of bioaccumulation in the food chain; reduced catches of bony fish in high-carbon sediment areas; FDA closure of extensive areas to shellfishing; enrichment resulting in increased phytoplankton productivity, the occurence of finrot, exoskeleton erosion, and gill clogging in certain marine life; and sediments in the vicinity of the dump sites devoid of normal benthic biological communities. The Congressional mandate has spurred sewage sludge generators to develop and implement alternate disposal methods. All options available have associated environmental risks since metropolitan area sludges contain pathogens, toxic metals, and persistent synthetic organic materials. No matter what method is chosen--landfill, incineration, pyrolysis, composting or recycling, some environmental impact will result.

Prevailing winds and currents carried the oil in a northeasterly direction, causing pollution of the coastal embayments and beach areas in the States of Sao Paulo and Rio de Janerio. In an attempt to protect recreational and other public use areas, particularly the popular beaches of Ubatuba, undiluted dispersants were applied to remove oil accumulations from the shoreline. This response action while it cosmetically removed oil from the surface of the beaches, caused the oil to penetrate more deeply into the underlying sand, thus compounding the pollution and aesthetic problems attributable to the spill incident. Preliminary follow-up studies, conducted seven months after the incident, verified the persistence of the detergent-treated oil in the beach sand.

Eventually, they will play a role in the sole source aquifer designation and management process, and the siting and regulation of pits, ponds, lagoons, sanitary landfills and waste treatment facilities. Examples of successful 208 planning agencies are: Nassau-Suffolk Regional Planning Board (NY); Old Colony Planning Council (MA); and Ventura County Regional Sanitation District (CA). These agencies have used funds to identify problems such as salt-water intrusion and contamination from storm runoff. Through ground water studies, each assessed the extent of the problems and used their analysis to produce protection and control recommendations. Integration of 208 with other Clean Water Act programs as well as with programs established under the Safe Drinking Water Act and the Resource Conservation and Recovery Act are now being explored as a means of increasing water quality management efficiency and capability.

A series of unit operations which could be combined in different ways comprised equalization, lime coagulation, sedimentation, ammonia stripping, activated-sludge treatment, carbon adsorption, and chlorination. The most effective sequence included equalization, lime coagulation and clarification, ammonia stripping, activated-sludge process and final chlorination. This sequence was capable of meeting the consent conditions for discharge to the Delaware river, although limits for BOD and lead were occasionally exceeded, and satisfactory ammonia removal was achieved only following the provision of two aerated lagoons. Phosphorus deficiency in the activated-sludge plant was corrected by the controlled addition of phosphoric acid at the inlet to the aeration tank. JF - Municipal Solid Waste: Land Disposal.

The concentration profile of leachate production over a period of several years is described and the essential parameters for the construction of a mathematical model for predicting concentration and amounts of leachate generated as a function of time are considered. Comparisons between predicted and measured results are presented based on the use of two models expressing both the total solids concentration and the weighted mean COD as a function of cumulative leachate volume. The basic requirements of a practical model which takes into account the site conditions and a gradual filling operation are presented as the basis for a model specification.

Total petroleum hydrocarbon concentrations were determined gravimetrically in stormwater emanating from a northern Philadelphian storm sewer. Comparison of hydrocarbon and sulfur fingerprints of the aromatic fractions of environmental samples to reference oils indicated that crankcase oil was the most likely source of aromatics in stormwater runoff. A weathering study on used crankcase oil showed a loss of diaromatics accounting for their absence in the environmental samples. A method of transport by which land-based oil enters the aquatic environment and receiving water sediments was proposed. Dibenzothiophene was identified in the environmental samples by retention time and mass spectrometry. Concentrations of dibenzothiophene in stormwater runoff ranged from 44.2 to 62.3 ng/L.

AN - 75043548; 400897 AB - Activity measurements are expected to have widespread use in toxicity testing. The multifaceted nature of motor activity will directly influence the selection of a measurement technique since the relative contribution of various motor acts to any particular measurement will depend upon the detection method. Because of the apparatus-dependent nature of motor activity measurements, it is recommended that consideration be given to how accurately the various devices measure locomotor activity. In the present paper, two types of body movement will be considered as locomotor activity: ambulation (horizontally directed movement) and rearing (vertically directed movement). Discussion focuses on the various methods currently used to record motor activity, the various components of motor activity which are likely to be recorded, and the advantages and disadvantages of these techniques for the measurement of locomotor activity. Finally, consideration is given to studies which have compared treatment effects on motor activity derived from two or more measurement techniques.

Age of fish had relatively little effect upon the results. The most intense LAN color production was in epithelial cells of midgut, pyloric ceca, hindgut, and in some segments of kidney tubules. Lower levels of LAN were evident in liver cells of Kupffer, and still lower or slight levels of LAN activity were found in blood cells, muscle, nerve, connective tissue, gonad, and pancreas. The results indicate that LAN might be useful in assessing histotoxicity to LAN-rich areas of the body.

The Environmental Protection Agency (EPA) was aurorized to provide technical and financial assistance to aid in attaining these goals. However, the large number of programs and lack of coordination greatly showed the implementation process at the local level. Emphasis is now being placed on State/EPA agreements to facilitate the implementation of the various programs and funds. The Clean Water Act Amendments of 1977 are expected to encourage more small town use of construction grants for waste treatment systems by simplifying government requirements of the states and local areas. Beginning in 1980, State/EPA agreements will be expanded and will involve all of the programs under the Resource Conservation and Recovery Act and the Safe Drinking Water Act. It is hoped that States will begin to develop overall environmental planning and management programs instead of making small individual efforts. Program coordination efforts are suggested for: (1) data collection for population and wasteload projections for all programs, (2) monitoring efforts for all programs, (3) water quality assessments for both surface and ground-water resources, (4) effective facility planning, and (5) wasteload allocations.

About 24% of the projects has a high degree of coordination between project sponsor and State water quality management programs, 43% had a low degree of coordination, and 33% had almost no coordination. On the Federal level, high coordination indicating active participation by another Federal agency was found in 17% of the projects, low coordination in 20%, and no coordination in the rest of the projects. These results indicate that: (1) a clear set of objectives and priorities needs to be developed at the State level, (2) more emphasis is needed on preventative and curative restoration measures, (3) a comprehensive water quality management program is needed, and (4) all applicable programs in specific project areas need to be coordinated. New State/EPA agreements are expected to help with coordination. Also expected to help is section 208 of the Clean Water Act which can be used to initiate and manage projects. The Model Implementation Projects (MIP's), a series of projects with similar objectives to the clean lakes programs have resulted from 208 planning. Project examples are Broadway Lake in South Carolina and Lake Herman in South Dakota. Continued program integration is needed to provide more effective water quality management.

From these standards a state can then determine the water quality criteria necessary to meet the standards. Once the standards and criteria have been determined, appropriate steps must be taken to protect the body of water for its selected use. Possible steps include preventing runoff from the watershed, control of wastes from industry and agriculture, and control of sewage treatment plant wastes. The Environmental Protection Agency 's clean lakes program is designed to help states with setting water quality standards, determining the needed criteria, and the necessary steps. Also, the program provides funding to help states carry out the necessary steps such as to control of nonpoint source pollution in watersheds and the correction of in-lake pollution problems. Other programs , agencies, and services that can be integrated with the clean lakes program include: the 208 water quality management program; the National Pollutant Discharge Elimination System (NPDES) permits program; the 201 construction grants program; the Agriculture Soil and Conservation Services; the Community Development Block Grant program; the Appalachian Commission; the Land and Water Conservation Fund; the Agriculture Stabilization and Conservation Service; the Energy, Environment, and Natural Resources Program; and the Land and Water Conservation Fund.

EPA prepared an environmental impact statement for the project in 1975. The original proposed waste water treatment facility was a two-stage activated sludge plant, with tertiary sand filters, phosphorus removal, and chlorination. However, due to the high natural quality of the Olentangy Rivers, EPA concluded that the residual chlorine concentrations that would be released into the river would be extremely hazardous to the river 's quality. The Olentangy River is a State Scenic River with good dissolved oxygen levels, a high diversity of aquatic insects, a variety of mollusks including four state endangered species, a wide biological diversity, and is one of the few remaining natural stream segments in central Ohio. Alternative disinfection agents considered were ozone, sulfur dioxide effluent dechlorination, bromine chlorine, and ultraviolet light. Ozone was selected because it is produced on site and does not have to be stored, it has been used for several years in drinking water with no observed toxic effects, and it does not increase instream levels of dissolved solids. While ozonation was more costly than chlorination in terms of monetary investment, it was less costly in terms of social and ecological factors. Text of a brief discussion on the paper is included.

The Federal government became involved in 1972 with the enactment of the Federal Water Pollution Control Act. In 1975, Federal financial support became available to states for their water quality programs. Since then $36.3 million have been appropriated for this purpose. Actual project costs are approximately twice this amount since Federal support represents only about 50% of the total funding. Federal funding through the Environmental Protection Agency 's clean lakes program has been used to support water quality restoration projects in 73 lakes in 23 states. The program is primarily directed toward the control of nonpoint pollutants and the implementation of methods to hasten lake recovery after the control of the pollutants. In 1978 EPA made funds available to states to inventory the extent and nature of eutrophication in significant lakes and to support feasibility studies for those methods most suited to restore lake water quality. EPA is currently developing regulations for the future management of the clean lakes program. Increased EPA/State agreements should make the program more effective. Future program focus will deal strongly with the impacts of nonpoint source pollutants and on the methods, management planning, and implementation of best management practices to correct the pollution sources.

Lake inventories for the area include results from 34,000 lakes or 36% of the national lake total for the 48 contiguous states. Lake surveys and classifications are expected to increase in frequency and intensity as closer relationships develop between performing agencies. Region V currently has 18 Environmental Protection Agency grants totaling $17.3 million. Of the projects , 71% are for watershed controls for urban or agricultural nonpoint source drainage. Program focus is predominantly on urban lakes, especially in Minnesota for the Twin Cities area. Dredging is the predominant technique used for correcting effects of past abusive land use practices. Although none of the 18 projects has yet produced sufficient data to measure its success, seven projects have shown some favorable results. Most notable are the White Clay and Mirror Lake projects both of which have produced beneficial results. The region is supplying additional manpower to provide pre-application assistance and program administration assistance. A handbook is being developed to assist communities in assessing the degree of lake pollution from septic tanks.

The objectives of the Ambient Water Quality Monitoring Network (AWQMN) are: 1) to establish baselines of water quality; 2) to characterize and define trends in the physical, chemical, and biological condition of the state 's surface waters; 3) to provide for a continuing assessment of water pollution control programs; 4) to identify and quantify new or existing water quality problems or problem areas; and 5) to act as a trigger mechanism for intensive surveys or other appropriate actions. Because objectives of the AWQMN were defined before it was designed, siting factors could be selected and priorities determined to best achieve those objectives. Ten site selection criteria were established, including at least one sampling site in each segment, networks of about 220 stations, availability of flow data, and maintenance of current data files. Sites with similar characteristics should be identified and grouped for analysis purposes. Each station can, therefore, be considered in one, two or more of seven sub-networks of the total AWQMN plan. The frequencies of sample collection are guided by the objectives of the AWQMN. Types of sampling include grab sampling, composite monitoring and automated continuous monitoring. The Illinois Environmental Protection Agency and the U.S. Geological Survey have a cooperative program under which USGS monitors a portion of the network and provides flow data at most network stations as well as extensive manpower training, equipment, data processing, and program quality control. Informal agreements with other agencies have permitted reduction in monitoring efforts required by the Illinois EPA.

To provide that frame of reference, the 50 States were contacted and representatives were questioned as to the nature and extent of their existing groundwater programs. The survey of States produced a wealth of information relative to the structure of various State programs, and this information was presented graphically in the neutral presentation. The subject of multiple agency involvement was addressed. In addition to looking at the structure of State programs, information was collected regarding the nature of existing State statutes and regulations. Tabulation and interpretation of this information were provided to illustrate how the institutions are providing for the protection of our groundwater resources. In addition to evaluating the various types of statutes, existing enforcement mechanisms were researched and presented for review. Graphic presentations of the national data base were used, and again several States ' procedures were reviewed in detail. The topic of groundwater quality standards was specifically addressed during interviews in order to note the extent of this developing regulatory technique. The presentation provided a national look at existing groundwater programs with in-depth analysis of certain State programs. The variations in State programs were highlighted and an attempt was made to estimate resources currently dedicated to groundwater protection at the State level.

The role of EPA in agricultural research was discussed in terms of both the nature and extent of activities, within the context of cooperation with the agribusiness community. Reliance on typical soil and water conservation measures as best management practices for maintenance of water quality was viewed from the perspective of present technical knowledge and system assessment capabilities. Additional studies necessary to confirm the link between water quality and best management practices were suggested. It was suggested that improved monitoring techniques, instream water quality surveys, and a better understanding of sediment/pollutant adsorption and desorption mechanisms are required in the near future to sharpen the guidelines for establishing agricultural nonpoint source management systems. Needed area-wide pollution problem assessment methodologies, BMP field evaluation, mathematical modeling of transport phenomena, and predictive techniques for BMP system comparisons were outlined. The projected extent of EPA/ORD involvement in these future activities was examined in light of potential resource availability and was compared with similar activities in other Federal, State, and local agencies and institutions.

From LC50 data obtained in different test waters, it is clear that calcium ion is very protective while magnesium, sodium and sulfate ions and the carbonate system give little or no protection. While precipitation may have influenced LC50 values slightly, it was concluded that the influence could not have been great because precipitation amounted to no more than about 40% of the cadmium present. No precipitation was detected at 15 microg/l nominal concentration, a level at which 90 to 100% mortality was observed in waters low in calcium but at which little or no mortality was observed in waters high in calcium.

Federal regulations, however, must provide flexibility to States and industry to find the least costly means of meeting national environmental goals. A growing body of literature clearly documents cases of underground drinking water source contamination, sometimes severe, from a large variety of conditions and practices. Existing studies also indicate that this problem is pervasive: aquifers have been adversely affected in every region of the country. A federal groundwater protection program which (1) reflects consideration of total long-range natural resource protection and environmental quality benefits, (2) regulates in a manner so that the benefits to the environment generally exceed the regulatory costs, and (3) encourages more efficient ways of meeting environmental goals in the least costly manner can and must be developed by the Environmental Protection Agency. Without an effective Federal groundwater protection program, the underground contamination problem will likely worsen. (Sims-ISWS) JF - Ground Water Vol. 17, No. 1, p 80-82, January-February 1979.

The cost distribution should be equitable and stable (in the sense that incentives for groups to break away and form separate systems are minimized). Concepts of n-person cooperative game theory are utilized to develop quantitative measures of equity and stability. These measures are incorporated into linear programming models that allow explicit equity-stability tradeoffs to be made in distributing the costs of the least-cost regional service plan. Examples that demonstrate the use of the methods are provided.

In building the new program, we should use the host of lessons learned in the experience of related environmental programs. This is necessary so that the new program will be realistic at the outset and congruent with the integrated planning and management of the ground- and surface-water resources of the nation. The keystone of program development, implementation, and evaluation is and will continue to be water quality standards. To the extent that the goal ' Safe Drinking Water for Americans ' has already been established, the point-of-use regulations should serve as water quality objectives, thus facilitating groundwater program formulation and evaluation. The major regulatory thrust of the program, the water quality standards, must be technology-based site selection, construction and operational standards, with only limited monitoring in a conventional water supply and water pollution control context.

The Environmental Protection Agency is about to launch a number of programs designed to protect what is , in many cases, a virtually nonrenewable resource. Separate regulatory activities mandated under the Safe Drinking Water Act , the Resource Conservation and Recovery Act, and the Clean Water Act must be coordinated carefully if they are to be effective. The current implementation efforts within the agency are being framed in view of our major principles which will be the focus of public comment in the months ahead. These principles are: (1) The administration of the related programs will be a cooperative effort involving Federal, State and local governments, all of which must participate in formulating the program if it is to be effective. (2) The focus of the programs will be on the prevention of contamination rather than on its treatment at the point of withdrawal. (3) The applicable standards will be based primarily on technology rather than ambient groundwater quality considerations since the effects of discharges upon ambient quality are complex, difficult to predict, and of long duration. (4) There is a need to balance environmental protection, energy development, and continued economic prosperity objectives so that the resulting programs fully protect public health while being realistically implementable. All of us--government, industry and citizens, through acts of commission or omission--have contributed to the potential problem. We must work together if we are to get on with the important task of protecting the quality of the Nation 's groundwater resources.

Characterization of the relevant relationships between physical exposure and the effects of noise on people has been fostered through the use of a wide variety of sound descriptors. Many of these descriptors were historically derived from sets of contours representing judgments of loudness, noisiness, or acceptability of sound. Many of these evolved merely as variations of one another. The apparent differences between the many assorted descriptors are simply due to differences in treatment of the many acoustic and non-acoustic parameters which are known or thought to influence human response to sound. The purpose of this tutorial paper is to review some of the more common sound descriptors used to portray our acoustic environment, as well as their derivations, formulation, applicability, and limitations.

Several species, especially the spiny dogfish, contained residues of DDT or its metabolites and PCB in the range 1-10 g per g of liver tissue. The levels of DDT encountered suggested that the pesticide had accumulated over periods of up to 20 years. JF - Aquatic Toxicology.

Since the cost of conventional sewerage rises prohibitively as the population density decreases, and the collection costs may represent 75 per cent of the total sewage charges, a decentralized form of treatment becomes an economic necessity. Either soil-dependent or non-soil dependent systems may be adopted, according to local climate and conditions. Septic tank installations required planned maintenance for effective operation, and the effluent from a large number of such systems may require too large an area of land; however small-diameter pressure sewers connected to a sewage lagoon or other treatment facility may provide an economic alternative to sub-surface disposal of septic tank effluents from adjoining properties.

A significant number of outbreaks and illnesses occur because of the lack of treatment of ground water and because of the interruption of disinfection of contaminated ground water. In non-municipal systems, the use of untreated ground water accounted for 44 per cent of outbreaks, and 44 per cent of the illness in these systems. Treatment deficiencies caused 34 per cent of outbreaks and 50 per cent of illness in the same systems.

Cadmium concentrations from 0.1 to 1.0 mg per litre were tested in aerated Plexiglass mixing and distribution chambers. Regression analysis was used to describe the relationship between percent larval mortality to cadmium concentration and constant salinity. Eggs reared in the fluctuating salinity responded to the influence of that range of salinities most frequently encountered during cadmium exposure.

Turbidity has been kept to less than 01 Ntu and detecting capcity for amphibole fibres is now 0030 x 10 6 fibres per litre. This was achieved in treating Lake Superior water whose fibre counts rose to 1 billion fibres per litre during storm conditions. The success of the filtration plant has led to vastly improved water quality in reservoirs and distribution systems. Aluminium sulphate solution is used as primary coagulant, sodium hydroxide for pH control and non-ionic polymers for amphibole fibre removal. The use of fluoride has made possible a lower alum dose.

No.2026) . After three years total phosphorus and solube reactive phosphorus concentrations had declined from 50 and 21 ug per litre to 30 and 45 ug per litre. A form of the phosphorus residence time model, incorporating the feedback of phosphorus from the sediment, accurately predicted the phosphorus patterns over the first three years. Inflow from rivers, atmospheric precipitation and waste water, and outflow via evaporation and ground water showed corresponding seasonal variations, reflected in phosphorus values, with a major deviation from predicted total phosphorus levels in July and August. There was a significant increase in algal biomass during these months.

The minnows are analysed, 5 at a time, after 2, 4, 8, 16, 24 and 32 hours. A first-order uptake model is used and the steady-state bioconcentration factor is calculated from the 32-day exposure. A structure-activity correlation between bioconcentration factor and the n-octanol/water partition coefficient permits estimation of factor to within 60 per cent, before analysis. Bioconcentration factors derived from tests of mixtures of chemicals are shown to be the same as those derived from tests with individual chemicals.

The release of effluent from septic tanks is considered as presenting a possible threat to the purity of groundwater supplies, while the injection of oxygenated water into an aquifer in the area surrounding a supply well has been shown to stimulate certain desirable bacteria, thus improving the output and quality of water produced. Studies of the rate of migration of viruses and bacteria in the soil and porous media have also been reported. 49 ref.

Some of the changes may be viewed as desirable, others undesirable, according to their nature and motivation, although all may upset the original ecological balance between different species . The contrasting values assigned to community function by different groups of individuals are discussed, including empirical relations between value and size of certain aquatic communities. Other parameter such as primary production, photosynthesis and total biomass may be important from an ecological viewpoint. The problem of interpreting laboratory data against such a complex background of values and ecological changes is broadly discussed and certain discrepancies between laboratory data and subsequent field testing are briefly considered.

Mortalities occurred at all concentrations tested; at concentrations of 11 g per litre and above over half died during the 42-day experiment. Ten per cent died at the lowest concentration of 5 g per litre. Growth was inhibited at all concentrations. Copper appears to cause detachment of the scallop prior to death, some did adjust to the copper and re-attach themselves. Scallops are shown to be very sensitive to copper.

From the available information they conclude that, because of marketing practices and the types of crops grown on sludge-amended soil, health effects from cadmium in sludge applied to agricultural land are not likely to be a problem. In addition, there is so far no epidemiological evidence to suggest that actual human illness has been caused by the use of sludge on land, where the sludge has been properly treated and applied. Dairy cows should not be permitted to ingest sewage sludge, since many organic compounds, which may adhere to plants, tend to accumulate in lipid-rich tissues and fluids such as milk.

The results of monitoring of ground-water for molybdenum, selenium and radioactive isotopes are reported, together with several case histories of groundwater pollution at uranium mill sites and tailings piles in 8 western states. The results demonstrate the influence of hydrogeological conditions in determining the pattern of migration and also the deficiencies in the present state of knowledge concerning long-term behaviour at such disposal sites. In the light of the proven inability to prevent the spread of pollution of ground-water at several sites, more stringent monitoring and control procedures have had to be introduced.

A model is developed for three waterborne diseases to illustrate the feasibility of the approach, which can be used for contaminants other than biological factors. Although both benefits and costs are necessarily estimates, the model lends perspective to and indicates trends for estimating the cost of a water quality improvement as opposed to its health benefits.

Loughlin AN - 19205790; 8003137 AB - This comment takes exception to Loughlin 's (1977) (See W78-02186) examination of three schemes for allocating costs of multipurpose projects to individual purposes with respect to a set of equity and efficiency criteria. Loughlin concluded that only the separable costs-remaining benefits (SCRB) method will satisfy the equity criterion. Two objections are raised: (1) Certain of the efficiency criteria should not be used for evaluating cost allocation methods; the criteria in question are actually project evaluation criteria and should be applied to the project before any cost allocation is made. (2) Loughlin 's adjusted SCRB method actually gives less-equitable results than the original SCRB formula for projects where the justifiable costs with a purpose deleted are given by the alternative cost of providing all other purposes. A revised set of cost allocation criteria separate from the economic evaluation criteria and thus in keeping with the equity principles used by Loughlin would be: (1) The sum of total costs allocated to each purpose should equal total project cost. (2) The total costs allocated to each purpose should not exceed the cost of a single purpose alternative providing equivalent benefits. (3) Savings allocated to each purpose should be in the same proportion as savings realized by including each purpose in the project. The remedy to the problem of the SCRB formula not satisfying the equity criterion is simply to redefine the separable cost of a purpose as the total project cost minus the justifiable cost with this purpose deleted.

However, even in the absence of such charges, municipal treatment plants have been constructed for many years, an indication that to a significant degree, states and communities have internalized the pollution costs of waste water discharges. The motivation for such investments varies widely, however, since before secondary treatment became a Federal requirement, the percentage of the sewered population in a state receiving such treatment ranged from 9 in New Hampshire to 100 in New Mexico. Using regression techniques, this analysis explains 40-45% of the variation in treatment levels among states in 1968 in terms of factors such as the availability of assimilative capacity relative to waste loads and the recency of urban development. The results of state and local programs appear to have been rational, broadly speaking, more extensive treatment being applied where pollution impacts would be greater. Some of the economic implications of the construction grant program, which provides an added incentive for treatment plant investment , are discussed in the light of these results.

The zinc concentrations utilized were 30 to 112 mu g/liter during the adult-to-smolt exposure period, and an additional 242 mu g/liter concentration was used for the embryo-to-smolt exposure period. These zinc concentrations produced no adverse effects on survival, fertility, fecundity, growth, or on the subsequent survival of smolts transferred to seawater. Exposure to 242 mu g/liter produced sufficient acclimation to markedly decrease acute mortality at zinc levels lethal to unacclimated sockeye salmon juveniles. The 112- and 242- mu g/liter concentrations were 0.15 and 0.32, respectively, of the 749- mu g/liter, 96-h LC50 for the 8-mo-old sockeye salmon. An application factor relating 96-h LC50 and 'safe' concentrations of zinc to anadromous sockeye salmon in soft water appears to be >0.15 and at least 15 times larger than the often recommended 0.01 application factor for zinc based on studies with other species.

Newly hatched alevins were much more tolerant to cadmium and, to a lesser extent, to zinc than were later juvenile forms. However, the later progression from swim-up alevin, through parr, to smolt was accompanied by a slight increase in metal tolerance. The 96-h LC50 values for all four life stages ranged from 1.0 to >27 mu g Cd/liter, 17 to 38 mu g Cu/liter, and 93 to 815 mu g Zn/liter. Steelhead were consistently more sensitive to these metals than were chinook salmon. When a sensitive life stage for acute toxicity tests with metals is sought, the more resistant newly hatched alevins should be avoided. Although tolerance may increase with age, all later juvenile life stages are more sensitive and should give similar results.
