Two fracture sets dominate the Lisburne Group carbonates of the North Slope subsurface and the nearby northeastern Brooks Range fold and thrust belt. North-northwest-striking regional extension fractures probably formed in front of the northeastern Brooks Range fold and thrust belt. In the North Slope subsurface, this fracture set overprints east-northeast-striking fractures related to earlier extensional deformation; in contrast, in the fold and thrust belt, the north-northwest-striking fracture set is overprinted by younger east-northeast-striking fractures related to subsequent contractional deformation. Lithology is the primary control on the fracture density of both sets. In mildly deformed Lisburne Group carbonates, grainstones are the least fractured and dolomitic mudstones the most fractured. However, structural position plays a greater role in the overall fracture character and density in folded and thrust-faulted Lisburne carbonates. Explorationists in the Lisburne Group and other potentially fracture-controlled or -enhanced carbonate reservoirs need to consider both carbonate lithology and structural position when developing predictive models for fracture development. Fracture character and density can change abruptly across a given area, and even across an individual structure. Rock types less prone to fracturing in the less deformed sections may experience the greatest relative increase in fracture intensity as deformation increases.

However, calculations of the flow properties of joints, whether simulated by continuous fields or discretely as a network of resistors, show that flow is maintained at appreciably larger contact areas. This behavior has been termed "channeling" in the literature. We have modified the standard effective media theory by introducing a rudimentary sort of nonrandomness in an attempt to simulate features like topographic hills and valleys. Using this new model, we calculate overestimates and underestimates of electrical and hydraulic conductivity as a function of the separation between the fracture surfaces. The underestimate is found to be very close to the standard effective media theory, real-space renormalization, and first-order perturbation theory results. The mean of the overestimate and underestimate is a good approximation to the published values found from calculations of electrical and hydraulic conductivities for simulations of real joints.

The results are used with pH-dependent polymer adsorption isotherms to isolate the fraction of sorption which is electrostatic allowing the magnitude of the non-electrostatic interactions (hydrogen bonding) to be determined. The results show that feldspar and quartz adsorb partially hydrolysed polyacrylamide (HPAM) in about the same amounts, while kaolinite adsorbs HPAM by a factor of approximately 3 higher suggesting that kaolinite has more sites available for adsorption. The difference in reactive site density may be due to the larger number of basal plane H-bonding sites on kaolinite. The results apply to clean mineral surfaces; many organic molecules sequester into weathered 'dead-end' pores on mineral surfaces.

The unique feature of this instrument is its ability to acquire permeability data at multiple sample supports subject to consistent boundary conditions and flow geometries. This device has been employed to physically investigate the permeability upscaling characteristics of a block of Berea Sandstone. Results reveal a number of consistent and distinct trends relating key summary statistics to changes in sample support. Comparisons are drawn between trends in the sample mean measured on the Berea Sandstone and that predicted by three theoretical upscaling models representing three common but different approaches to modeling permeability upscaling.

Three-dimensional fluid flow and heat transfer simulations have been performed for soil-heated vapor extraction to determine the transient system performance for a hypothetical configuration. Soil layering has been considered in evaluation of the initial non-aqueous phase liquid (NAPL) distribution and in evaporation and transport to the vapor extraction location. Results from this layered model are compared with results for a homogeneous system with an initially uniform NAPL, indicating the influence of layering, the initial NAPL distribution, the type of NAPL, and the possibility of enhanced vapor diffusion. Not only is the NAPL removal time reduced significantly with the addition of heat, but the uncertainty in the removal time owing to a number of difficult to characterize in situ factors, such as layering and the initial NAPL distribution, is much less than for standard soil vapor extraction without heating, owing to the rise in temperature and increase in NAPL vapor pressure with time.

Volume average temperatures of 83 degrees C and 112 degrees C were reached for the PLF and RF heating periods, respectively, within the 15 ftX45 ftX18.5 ft deep treated volume. This resulted in the removal of 243 lb of measured toxic organic compounds (VOCs and SVOCs), 55 gallons of oil, and 11,000 gallons of water from the site. Reductions of up to 99% in total chromatographic organics (TCO) was achieved in the heated zone. Energy balance calculations for the PLF heating period showed that 36.4% of the heat added went to heating the soil, 38.5% went to evaporating water and organics, 4.2% went to sensible heat in the water, 7.1% went to heating the extracted air, and 6.6% was lost. For the RF heating period went to heating the soil, 23.5% went to evaporating water and organics, 2.4% went to sensible heat in the water, 7.5% went to heating extracted air, and 9.7% went to losses. Energy balance closure was 92.8% for the PLF heating and 98% for the RF heating. The energy input requirement per unit soil volume heated per unit temperature increase was 1.63 kWH/yd (super 3) - degrees C for PLF heating and 0.73 kWH/yd (super 3) degrees C for RF heating.

Low Damkoehler numbers yield long, low-amplitude elution tails, which contain much of the total solute. As a consequence, at Da nearly equal 0.18 and K (sub D) =8, the solute peak travels at the same speed as the carrier fluid, yielding an apparent K (sub D) nearly equal 0 after five characteristic diffusion times. Such conditions correspond, for example, to a meter-long path through a 0.5-cm-wide, gas-filled fracture. Buoyancyenhanced dispersion, found in experiments with horizontal tubes, is confirmed by the LGA analysis; however, a different mechanism is suggested for the enhancement in horizontal fractures. Both kinetic and buoyancy errors can be greatly reduced, or experiments made much smaller, if the first and second moments of a tracer pulse can be measured as functions of time.

Ross [1990] has developed a relationship for the steady-state diversion length of tilted capillary barriers assuming the quasi-linear set of two-phase characteristic curves. Due to its simplicity, this equation has been used to evaluate potential tilted capillary barrier performance even in cases where the layer characteristic curves are different than the quasi-linear equation set. In the present study, Ross" capillary barrier diversion relationship is extended to other two-phase characteristic curves.

The depositional environment that produced these sandstones is interpreted to have been fluvial, wherein episodic flooding of a sand-choked system produced rapid deposition that kept pace with rising flood waters. This resulted in shallow-water, high-energy, sheeted deposition. This interpretation is supported by abundant parting lineation, and local crossbedding showing alternate building of topsets and foresets (rising-water structures). Rapid deposition is also suggested by post/syndepositional compaction shears, and common soft-sediment deformation due to post-depositional dewatering. Scattered pebbles up to 4 cm diameter were moved in this generally northward-flowing system. Local lateral accretion structures suggest that a meandering system existed between floods, but that the bedding units and sedimentary structures produced by flooding had the highest preservation potential.

Although the two intervals are separated vertically by only 140 ft, the fracture systems in the two intervals are dissimilar: the upper interval has regularly spaced, sub-parallel fractures, whereas the lower interval contains two intersecting sets of irregularly spaced fractures. Fractures of each of the three sets have characteristic and distinctive orientations, orientation distributions, spacing distributions, surface features, and mineralization. An estimate of the subsurface fracture lengths can be made by correlating fracture spacings in core with the spacing-length relationships measured in outcrops of the Brushy Canyon Formation (a younger but lithologically similar formation, deposited in similar environments in the Delaware basin). Fracture orientations and spacing/length distributions from outcrop can be used in a tensor model to determine effective permeability of the field. This can in turn be used to model production in the Spraberry reservoir.

The Main Drift is the planned 3,131-m near-horizontal tunnel to be excavated at the potential repository horizon for the Yucca Mountain Site Characterization Project. Specific data summarized and presented included lithologic and rock structure core logs, rock mechanics laboratory testing, and rock mass quality indices. Cross sections with stratigraphic and thermal-mechanical units were also presented. Topics discussed in the report include geologic setting, geologic features of engineering and construction significance, anticipated ground conditions, and the range of required ground support. Rock structural and rock mass quality data have been developed for each 3-m interval of core in the middle nonlithophysal stratigraphic zone of the Topopah Spring Tuff Formation. The distribution of the rock mass quality data in all boreholes used to characterize the Main Drift was assumed to be representative of the variability of the rock mass conditions to be encountered in the Main Drift. Observations in the North Ramp tunnel have been used to project conditions in the lower lithophysal zone and in fault zones.

The goals of this project are to show that diffusivity can be measured in core samples of soil jet-grouted with Portland cement, validate the experimental method through measurements on samples, and to calculate aqueous diffusivities from a series of diffusion measurements. This study shows that it is practical to measure SF6 diffusion rates in the laboratory on samples of grout (Portland cement and soil) typical of what might be used in a barrier. Diffusion of SF6 through grout (Portland cement and soil) is at least an order of magnitude slower than through air. The use of this tracer should be sensitive to the presence of fractures, voids, or other discontinuities in the grout/soil structure. Field-scale measurements should be practical on time-scales of a few days.

Published data have been evaluated as the input parameters that are used in the simulation of the fate and transport processes. A one-dimensional model developed for screening agricultural pesticides was modified and used to simulate the appearance of a surface flux above a buried landmine, estimate the subsurface total concentration, and show the phase specific concentrations at the ground surface. The physical chemical properties of TNT cause a majority of the mass released to the soil system to be bound to the solid phase soil particles. The majority of the transport occurs in the liquid phase with diffusion and evaporation driven advection of soil water as the primary mechanisms for the flux to the ground surface. The simulations provided herein should only be used for initial conceptual designs of chemical pre-concentration subsystems or complete detection systems. The physical processes modeled required necessary simplifying assumptions to allow for analytical solutions. Emerging numerical simulation tools will soon be available that should provide more realistic estimates that can be used to predict the success of landmine chemical detection surveys based on knowledge of the chemical and soil properties, and environmental conditions where the mines are buried. Additional measurements of the chemical properties in soils are also needed before a fully predictive approach can be confidently applied.

Eight hazardous metals were evaluated: arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver. The analysis considered transport only through the groundwater pathway. The results are reported as site-specific estimates of maximum concentrations of each hazardous metal in treated mixed low-level waste that do not exceed the performance measures established for the analysis. Also reported are site-specific estimates of travel times of each hazardous metal to the point of compliance.

From 1989 to 1993 the cooling pond represented one of the major sources of (super 90) Sr migration from the Chernobyl site to the Dnieper River. Several attempts have been made to contain radioactive contamination within the pond. Overestimation of releases via groundwater pathway and design mistakes led to unsuccessful remedial actions in 1986 and in later periods. In addition, remediation criteria based solely on comparison of contaminant concentrations in groundwater with drinking water standards were not effective from the health risk perspective, because the public was not directly exposed to contaminated groundwater; the exclusion zone surrounding the site acted as an institutional control to prevent public access. In light of recent estimates of low risks due to radionuclide transport outside the exclusion zone, a "no action" approach may represent the most reasonable strategy for the near-term management of the cooling pond.

The geophysical studies have provided significant understanding of the nature of site deformation, tectonics and stability. Geophysical methods have delineated possible brine reservoirs beneath the underground facility and have defined the disturbed rock zone that forms around underground excavations. The role of geophysics in the WIPP project has evolved with the project. The early uses were for site characterization to satisfy site selection criteria or factors. As the regulatory framework for WIPP grew since 1980, the geophysics program was focused on support of experimental and field programs such as Salado hydrogeology and underground room systems and excavations. In summary, the major types of issues that geophysical studies addressed for WIPP are: - Issue 1: Site Characterization; - Issue 2: Castile Brine Reservoirs; - Issue 3: Rustler /Dewey Lake Hydrogeology; - Issue 4: Salado Hydrogeology; - Issue 5: Excavation Effects The nature of geophysics program for WIPP has been to support investigation rather than being the principal investigation itself. The geophysics program has been used to define conceptual models (e.g., the Disturbed Rock Zone-DRZ) or to test conceptual models (e.g., high transmissivity zones in the Rustler Formation). An effect of being a support program is that as new project priorities arose the funding for the geophysics program was limited and withdrawn. An outcome is that much of the geophysics survey information resides in contractor reports since final interpretation reports were not funded.

Eleven distinct EM systems, covering the geophysical spectrum, acquired data on a grid over the Idaho National Engineering Laboratory (INEL) Cold Test Pit (CTP). The systems are investigated and evaluated for the purpose of identifying and reviewing existing geophysical characterization instrumentation (commercial and experimental), integrating those technologies with multi-dimensional interpretational algorithms, and identifying gaps in shallow subsurface EM imaging technology. The EMID data, are valuable for testing and evaluating new interpretational software, and developing techniques for integrating multiple datasets. The experimental field techniques shows how the acquisition of data in a variety of array configurations can considerably enhance interpretation. All data are available on the world wide web (http://vetem.lbl.gov). Educators and students are encouraged to use the data for both classroom and graduate studies. The purpose of this paper is to explain why, where, how and what kind of data were collected. It is left to the reader to assess the value of a given system for their particular application. Information about the EMID is organized into two general categories: survey description and system evaluation.

The solution is obtained by successive linearized model updates where full forward modeling is employed at each iteration to compute model sensitivities and predicted data. Regularization is applied to the problem to provide stability. Because the inverse part of the problem requires the solution of 10's to 100's of thousands of unknowns, and because each inverse iteration requires many forward models to be computed, the code has been implemented on massively parallel computer platforms. The use of the inversion code to image environmental sites is demonstrated on a data set collected with the Apex Parametrics "MaxMin I-8S" over a section of stacked barrels and metal filled boxes at the Idaho National Laboratory's "Cold Test Pit". The MaxMin is a loop-loop frequency domain system which operates from 440 Hz up to 56 kHz using various coil separations; for this survey coil separations of 15, 30 and 60 feet were employed. The out-of phase data are shown to be of very good quality while the in-phase are rather noisy due to slight mispositioning errors which cause improper cancellation of the primary free space field in the receiver. Weighting the data appropriately by the estimated noise and applying the inversion scheme is demonstrated to better define the structure of the pit. In addition, comparisons are given for single coil separations and multiple separations to show the benefits of using multiple offset data.

The results allow some limits to be placed on the linkage between seafloor weathering and climate. To confirm the T dependence and to constrain any effect of PCO (sub 2) on rates, whole-rock basalt dissolution rates were measured using unaltered pillow basalt from the Southern Rift Valley of the Eastern Galapagos Rift. The results indicate extensive Ca leaching and consumption of CO (sub 2) during basalt alteration. The primary linkage between seafloor weathering and the global C cycle appears to be thermal rather than chemical.

An algorithm for detecting and characterizing long-period Rayleigh-wave arrivals has been developed and tested. The routine continuously monitors all directions of approach to a station, in a manner similar to beamforming. The detector is based on cross-powers between the Hilbert-transformed vertical and rotated horizontal signals, so it is sensitive to both the power and polarization properties of the three-component wave field. Elliptically polarized Rayleigh arrivals are enhanced, while linearly polarized Love waves and body phases are suppressed. A test using one month of data from station ANMO demonstrated that this technique can, with high reliability, detect Rayleigh arrivals that are visible on the records. The measured arrival times and azimuths are accurate enough to permit automated association of the detections to events in a bulletin.

AN - 79154228; 10168958 AB - We have demonstrated high definition and improved resolution using a novel scanning system integrated with a commercial ultrasound machine. The result is a volumetric 3D ultrasound data set that can be visualized using standard techniques. Unlike other 3D ultrasound images, image quality is improved from standard 2D data. Image definition and bandwidth is improved using patent pending techniques. The system can be used to image patients or wounded soldiers for general imaging of anatomy such as abdominal organs, extremities, and the neck. Although the risks associated with x-ray carcinogenesis are relatively low at diagnostic dose levels, concerns remain for individuals in high risk categories. In addition, cost and portability of CT and MRI machines can be prohibitive. In comparison, ultrasound can provide portable, low-cost, non-ionizing imaging. Previous clinical trials comparing ultrasound to CT were used to demonstrate qualitative and quantitative improvements of ultrasound using the Sandia technologies. Transverse leg images demonstrated much higher clarity and lower noise than is seen in traditional ultrasound images. An x-ray CT scan was provided of the same cross-section for comparison. The results of our most recent trials demonstrate the advantages of 3D ultrasound and motion compensation compared with 2D ultrasound. Metal objects can also be observed within the anatomy.

This is largely due to the high levels of cultural noise and the preponderance of steel well casings. However, recent experimental success with crosshole EM systems for water and steam flood monitoring using fiberglass cased wells has shown promise in applying these techniques to development and production problems. This paper describes technological solutions that allow successful application of EM techniques in oil fields, despite surface noise and steel casings. Recent positive experience has been reported in applying crosshole EM where one of the wells is steel cased. Another example sites the application of long offset logging to map resistivity structure away from the borehole. The potential application of earth's field nuclear magnetic resonance (NMR) to map water saturation at large distances from the boreholes is also discussed.

While this is natural for Kirchhoff methods, it is more difficult for finite-difference methods for several reasons. First, the imaging condition is often convolutional in nature. This has the effect of multiplying the frequency content of the source and receiver traces and significantly changes the shape of the image wavelet. Second, finite-difference migrations actually propagate the derivative of the recorded pressures due to the presence of the free surface. These effects can be mitigated somewhat by using an Ornsby source wavelet and by dividing out the derivative effects during in the imaging.

In this area, the Rustler Formation consists of a layered sequence of mudstone, anhydrite, halite, and dolomite. Attention has been focused on the most permeable member, the Culebra dolomite. Three zones of differing predominant chemical constituents of groundwater (hydrochemical facies) are present in the Culebra in the vicinity of the WIPP. The flow direction indicated by the observed distribution of hydraulic head (from north to south) requires that groundwater flow from a zone of more saline NaCl-type water to a zone of more dilute CaSO4-type water if flow is at steady state and confined to the Culebra. However, there are no known sets of rock-water interactions that would transform the upstream, more saline water into the downstream, less saline water. Consequently, alternative conceptual models that involve transient and/or three-dimensional flow patterns have been proposed. This paper demonstrates that simulated three-dimensional flow fields that include Rustler members that underlie and overlie the Culebra are consistent with the observed hydrochemical facies. Simulation results suggest that the three water types have different recharge areas, different paths to the Culebra, interact with different rocks, and have extremely different flow rates and residence times. Solute chemistries of each hydrochemical facies can be explained by interactions with the evaporite rocks that occur along their respective flow paths.

Recovery/breakthrough curves from both single-well injection-withdrawal (SWIW) and multiwell tracer tests have tails that are believed to be the result of matrix diffusion. Numerical modeling studies have recently been conducted to evaluate diffusion parameters and whether the effects of heterogeneity on tailing can be separated from matrix diffusion. Numerical simulations of the SWIW test with heterogeneous single- and double-porosity models indicate that the gradual mass recovery cannot be the result of a combination of heterogeneity and regional drift. SWIW test interpretations demonstrate that matrix diffusion is an important process, but diffusion parameters are moderately correlated to fracture porosity, which cannot be confidently estimated from the SWIW. Numerical simulations of the multiwell tracer test data indicate that the early arrival portion of a tracer-breakthrough curve (BTC) is mainly controlled by fracture porosity. Single-porosity simulations with several conceptual models of heterogeneous transmissisivity fields were conducted to evaluate the role of heterogeneity in BTC tailing. The different types of transmissivity were created using geostatistical simulation. Transport modeling results on the heterogeneous fields indicate that the amount of tailing in a single-porosity medium is dependent on the style of heterogeneity, the correlation length of transmissivity, and the porosity. Simulations indicate that the multiwell tracer test is not as definitive a test for matrix diffusion as the SWIW test. However, it may be possible to use the multi-well test to rule out single-porosity transport through a heterogeneous domain if enough data are collected to define a constant late time BTC slope.

It is relevant to consider both ancient as well as modern mineralogic processes in the WIPP. The mineralogic evolution of the WIPP Site can be divided into three eras. The Delaware Basin initially filled with a thick sequence of alternating halite plus anhydrite. Occasional excursions into more extreme evaporitic conditions deposited small amounts of K- and Mg-rich minerals and bittern brines that later reacted with anhydrite to form abundant polyhalite. The second stage of the mineralogic evolution, beginning in the late Permian, involved interactions between the bittern brines and detrital clays. These reactions incorporated magnesium into the clays while liberating small amounts of silica, and possibly alumina. The result was an abundance of high-Mg mixed-layer clays similar to corrensite, and small amounts of authigenic quartz and potassium feldspar. Maturation of organic material contributed carbon for magnesite formation. The last stage in the evolutionary process will start once the waste is emplaced. The chemistry of the emplaced material will be dominated by the waste materials, iron containers, and the pelleted MgO emplaced as a backfill. Interactions between indigenous brine and the backfill will produce magnesium hydroxy-chloride, while CO2 produced by microbial activity will result in formation of magnesium carbonate. Initially a hydrous mineral such as hydromagnesite or nesquehonite will form, but will slowly dehydrate to form magnesite similar to that already present in the formation. The fate of corroded iron is less clear. However, MgO will establish a basic pH and the abundance of metallic iron will ensure that Fe+2 predominates over Fe+3. Under these conditions it is likely that members of the hydrotalcite-like "green rust" family of minerals will form.

Implementation included design, construction, and subsequent monitoring of an in situ passive reactive barrier to remove Uranium from the tailings pile effluent. A reactive subsurface barrier is produced by emplacing a reactant material (in this experiment various forms of metallic iron) in the flow path of the contaminated groundwater. Conceptually the iron media reduces and/or adsorbs uranium in situ to acceptable regulatory levels. In addition, other metals such as Se, Mo, and As have been removed by the reductive/adsorptive process. The primary objective of the experiment was to eliminate the need for surface treatment of tailing pile effluent. Experimental design, and laboratory and field results are discussed with regard to other potential contaminated groundwater treatment applications.

A close-coupled barrier is produced by first installing a conventional cement grout curtain followed by a thin inner lining of a polymer grout. The resultant barrier is a cement polymer composite that has economic benefits derived from the cement and performance benefits from the durable and chemically resistant polymer layer. The technology has matured from a regulatory investigation of issues concerning barriers and barrier materials to a pilot-scale, multiple individual column injections at Sandia National Labs (SNL) to full scale demonstration. The feasibility of this barrier concept was successfully proven in a full scale "cold site" demonstration at Hanford, WA. Consequently, a full scale deployment of the technology was conducted at an actual environmental restoration site at Brookhaven National Lab (BNL), Long Island, NY. This paper discusses the installation and performance of a technology deployment implemented at OU-1 an Environmental Restoration Site located at BNL.

The solution is obtained by successive linearized model updates where full forward modeling is employed at each iteration to compute model sensitivities and predicted data. Regularization is applied to the problem to provide stability. Because the inverse part of the problem requires the solution of 10's to 100's of thousands of unknowns, and because each inverse iteration requires many forward models to be computed, the code has been implemented on massively parallel computer platforms. The use of the inversion code to image environmental sites is demonstrated on a data set collected with the Apex Parametrics "MaxMin I-8S" over a section of stacked barrels and metal filled boxes at the Idaho National Laboratory's "Cold Test Pit". The MaxMin is a loop-loop frequency domain system which operates from 440 Hz up to 56 kHz using various coil separations; for this survey coil separations of 15, 30 and 60 feet were employed. The out-of phase data are shown to be of very good quality while the in-phase are rather noisy due to slight mispositioning errors, which cause improper cancellation of the primary free space field in the receiver. Weighting the data appropriately by the estimated noise and applying the inversion scheme is demonstrated to better define the structure of the pit. In addition, comparisons are given for single coil separations and multiple separations to show the benefits of using multiple offset data.

A critical part of this application was a Performance Assessment which predicts the cumulative radioactive release to the accessible environment over a time period of 10,000 years. Comparison of this predicted release to the EPA standard shows a comfortable margin of compliance. Evaluation of the geologic processes which are active in the site region establishes that there will be no natural breach of site integrity for millions of years, far longer than the 10,000 year regulatory period. Inadvertent human intrusion is, therefore, the only credible scenario to lead to potential radioactive release to the accessible environment. To substantiate this conclusion and to quantify these potential releases from human intrusion, it has been necessary to develop an understanding of the following processes: (1) salt creep and shaft seal efficacy; (2) gas generation from organic decomposition of waste materials and anoxic corrosion of metals in the waste and waste packages; (3) solubilities for actinides in brine; (4) fluid flow in Salado formation rocks, and (5) hydrologic transport of actinides in the overlying dolomite aquifers. Other issues which had to be evaluated to allow definition of breach scenarios were brine reservoir occurrences and their associated reservoir parameters, consequences of mining over the repository, and drilling for natural resources in the vicinity of the repository. Results of all these studies are briefly summarized in this paper.

This capability is critical to research in environmental remediation (e.g. contaminations with dense, non-aqueous-phase liquids), nuclear waste management, reservoir engineering, and to the assessment of the future availability of groundwater in many parts of the world. This paper presents an unstructured grid numerical algorithm for subsurface transport in heterogeneous porous media implemented for use on massively parallel (MP) computers. The mathematical model considers nonisothermal two-phase (liquid/gas) flow, including capillary pressure effects, binary diffusion in the gas phase, conductive, latent, and sensible heat transport. The Galerkin finite element method is used for spatial discretization, and temporal integration is accomplished via a predictor/corrector scheme. Message-passing and domain decomposition techniques are used for implementing a scalable algorithm for distributed memory parallel computers. Illustrative applications are shown to demonstrate capabilities and performance, one of which is modeling hydrothermal transport at the Yucca Mountain site for a radioactive waste facility.

Specific sources considered include dipolar and magnetotelluric (MT) field excitation in the frequency domain. In the forward problem, the EM fields are simulated using a vector Helmholtz equation for the electric field, which are approximated using finite differences on a staggered grid. To obtain the fields, a complex-symmetric matrix system of equations is assembled and iteratively solved using the quasi minimum method (QMR) method. Perfectly matched layer (PML) absorbing boundary conditions are included in the solution and are necessary to accurately simulate fields in propagation regime (frequencies >10 MHZ). For frequencies approaching the static limit (<10 KHz), the solution also includes a static-divergence correction, which is necessary to accurately simulate MT source fields and can be used to accelerate convergence for the dipolar source problem.

The method has been extensively studied for application in saturated clayey soils. Over the past few years, an electrokinetic extraction method specific for sandy, unsaturated soils has been developed and patented by Sandia National Laboratories. A RCRA RD&D permitted demonstration of this technology for the in situ removal of chromate contamination from unsaturated soils in a former chromic acid disposal pit was operated during the summer and fall of 1996. This large scale field test represents the first use of electrokinetics for the removal of heavy metal contamination from unsaturated soils in the United States and is part of the US EPA Superfund Innovative Technology Evaluation (SITE) Program. Guidelines for characterizing a site for electrokinetic remediation are lacking, especially for applications in unsaturated soil. The transference number of an ion is the fraction of the current carried by that ion in an electric field and represents the best measure of contaminant removal efficiency in most electrokinetic remediation processes. In this paper we compare the transference number of chromate initially present in the contaminated unsaturated soil, with the transference number in the electrokinetic process effluent to demonstrate the utility of evaluating this parameter.

Prediction of fluid flow in these zones must consider both the mechanical and fluid flow processes. Presented here is a methodology which utilizes a mechanical model to predict damage and disturbed rock zone (DRZ) development around the excavation and then uses the predictions to develop time-dependent DRZ porosity relationships. These relationships are then used to adjust the porosity of the DRZ in the fluid flow model based upon the time and distance from the edge of the excavation. The application of this methodology is presented using a site-specific example from the Waste Isolation Pilot Plant, a US Department of Energy facility in bedded salts being evaluated for demonstration of the safe underground disposal of transuranic waste from US defense-related activities.

The Hydrological Evaluation of Landfill Performance (HELP) computer code is an evaluation tool for landfill covers used by designers and regulators. HELP is a quasi-two-dimensional model that predicts moisture movement into and through the underground soil and waste layers. Processes modeled within HELP include precipitation, runoff, evapotranspiration, unsaturated vertical drainage, saturated lateral drainage, and leakage through liners. Unfortunately, multidimensional unsaturated flow phenomena that are necessary for evaluating tilted capillary barriers are not included in HELP.

Thus iterative methods must be employed. For the inverse problem, we favor either a linear or non-linear (NL) CG scheme, depending on the application. In a NL CG scheme, the gradient of the objective function is required at each relaxation step along with a univariate line search needed to determine the optimum model update. Solution examples based on both approaches will be presented.

Unfortunately, predicting fluid-flow response of fractured reservoirs is difficult because of the variability of the three dimensional fracture networks, permeability anisotropy, and interaction of fracture and matrix permeability. Integration of geological data from outcrops, logs and core with production and well testing data provides the most reliable approach to fracture characterization and fluid flow simulation. This approach has been applied to the Mesaverde formation were pressure interference was combined with fracture characterization from outcrops studies. The pressure interference provides information on the continuity, transmissibility, storage and anisotropy of the formation. Geological data gives information on fracture spacing and distribution. Fluid flow simulation confirm that fractures not only enhance the overall porosity and permeability of these reservoirs, but fractures also create significant permeability an isotropy. Permeability an isotropy causes the drainage area around the wells to be elliptical. The aspect ratio of the elliptical drainage area in these reservoirs is determined bye the magnitude of the permeability an isotropy and reservoir porosity. These results demonstrate that well spacing of 320 acre or 20 acre squares based on radial drainage is not relevant when fractured reservoirs have permeability anisotropy of up to 1000 to 1. Economic optimization of infill drilling using fewer wells can be accomplished if field development is based on elliptical drainage areas that lead to a reduction in drainage overlap of adjacent wells and prevents leaving undrained areas.

Examples from the Entrada Sandstone in Utah and from the Kaibab/Coconino sequence in Arizona show that although each domain may contain multiple sets of consistently oriented fractures, the orientations and patterns of the fractures vary significantly from domain to domain. Many of these fractures are related to local stresses created by subtle, irregular flexures resulting from mobility of the underlying evaporites. Multiple fracture sets result from multiple episodes of evaporite mobility and/or dissolution. The good news is that multiple sets of superimposed fractures result in reservoir-quality connectivity within restricted localities of the formation. The difficulty lies in trying to predict the orientations and characteristics of this type of fracturing in the subsurface, since these typically have little relationship to the regional tectonic stresses which are used to predict fracture characteristics prior to drilling. Nevertheless, the high probability of numerous and intersecting fractures in such settings suggests that fracture orientations may be an insignificant factor in the production of hydrocarbons from fractured reservoirs which developed this way.

Accurate knowledge of the mechanisms and rates of heterogeneous nucleation and growth of minerals is needed to develop realistic models of low-temperature geochemical systems. For example, growth and dissolution relationships between gibbsite and kaolinite are key to understanding weathering processes that lead to laterite and bauxite formation. We have developed a precise and accurate X-ray diffraction (XRD) method for measuring amounts of epitaxially grown gibbsite on kaolinite, using a custom built rotating-anode X-ray diffractometer (M. Beno and G. Knapp, Rev. Sci. Instr., 1993) at Argonne National Laboratory. This method can yield kinetic and structural data for analogous heteroepitaxial growth of many minerals.The method was calibrated using mechanical mixtures of gibbsite and kaolinite. Integrated peak areas from powder XRD scans for the kaolinite (001) and gibbsite (002) diffraction peaks were plotted against weight fractions of mechanical mixtures of gibbsite and kaolinite. The range of calibration is from 0 to 20 wt. percent gibbsite, and the regressed data show a near perfect linear correlation. Using a position sensitive detector and a high operating current (150-200 mA at 40 kV), we obtained good counting statistics and a low detection limit for gibbsite (0.1 wt. %).In a set of ongoing experiments, we are growing gibbsite on kaolinite powders at 80AC, pH 3 under variable saturation state conditions with respect to both phases. The preliminary XRD results obtained thus far on these experimental samples agree well with solution chemistry mass balance and with atomic force microscopy images. The XRD data verify that gibbsite was in the run products. The XRD data also can provide information on the epitaxy between gibbsite and kaolinite and on the average gibbsite domain size.

The hydrogeology is of interest because this unit is a possible pathway for offsite migration of radionuclides from a proposed repository for defense-generated transuranic wastes (the Waste Isolation Pilot Plant). The numerical model used is three-dimensional, extends laterally to topographic features that form the actual boundaries of a regional groundwater system, and uses a free-surface upper boundary condition to simulate the effect of change in the rate of recharge on groundwater flow. Steady-state simulations were performed to examine the sensitivity of simulation results to assumed values for hydraulic conductivity and recharge rate. Transient simulations, covering the time period from 14,000 years in the past to 10,000 years in the future, provided insight into how patterns of groundwater flow respond to changes in climate. Simulation results suggest that rates and directions of groundwater flow in the Culebra change with time due to interaction between recharge, movement of the water table, and the topography of the land surface. The gentle east-to-west slope of the land surface in the vicinity of the WIPP caused groundwater in the Culebra to flow toward and discharge into Nash Draw, a topographic depression. Modern-day flow directions in the Culebra reflect regional rather than local features of the topography. Changes in groundwater flow, however, lagged behind changes in the rate of recharge. The present-day position of the water table is still adjusting to the decrease in recharge that ended 8,000 years ago. Contaminants introduced into the Culebra will travel toward the accessible environment along the Culebra rather than by leaking upward or downward into other units. Natural changes in flow over the next 10,000 years will be small and will mainly reflect future short-term wet periods.

Such systems are being developed to monitor the effects of strain on geomembranes including the location of tears. Other possible measurements utilize moisture and fluid-level sensors. Since the use of geomembranes in geotechnical and environmental applications is widespread and monitoring systems are generally lacking, the potential for this technology is significant. For example, a geomembrane-and-sensor system addresses the need to monitor landfill stabilization in general and specifically the behavior of geomembranes used in liner and cover designs. We have demonstrated that glass and plastic fibers can be attached to a geomembrane (1) during extrusion and lamination and (2) by hot shoe welding, glued tape runners, and welded runners. Using these methods, we have manufactured 30 m lengths of geomembrane with continuous optical fiber across the length. Our preliminary focus has been on strain sensors to monitor landfill subsidence. We have utilized existing and newly developed strain sensors, e.g., microbend, Bragg grating, and adsorption band sensors. These sensors have been installed as arrays into several test membranes at a manufacturing scale (e.g., 3 to 4 m wide). The prototype monitoring systems were installed in laboratory test frames, and the sensors measured the strains across the membranes as they were loaded. We plan to scale these experiments up to the size of landfill cover system using a test cell under construction.

Mouse monoclonal antibodies specific for thiabendazole (a post-harvest fungicide and veterinary anthelmintic) were covalently linked through free amine groups to aminosilanized silicon dioxide films using glutaraldehyde. Immobilized antibody layers were stabilized with sucrose, dehydrated, and stored refrigerated with desiccant. Photolithographic patterning was performed with a positive photoresist with modified bake temperatures and times, selective UV exposure with a contact mask, and aqueous alkaline solubilization of exposed resist. Exposed regions of immobilized antibody were then removed by exposure to a low power, radio frequency oxygen discharge. Residual resist was stripped with acetone. Successful patterning was demonstrated by challenging surfaces with goat anti-mouse antibody conjugated to tetramethylrhodamine isothiocyanate. Sucrose stabilization was necessary for antibody to undergo photoresist processing without loss of binding activity. Challenge with enzyme linked antigen of oxygen plasma exposed antibody layers demonstrated that plasma treatment completely neutralized antibody capture ability. Ellipsometry measurements of oxygen plasma exposed antibody layers indicated complete removal of immobilized antibodies. Fluorescent imaging demonstrated smallest line widths of 2-3 mu m.

Molybdenum(VI) was reduced by washed cells suspended in bicarbonate buffer solution with either lactate or hydrogen as the electron donor. Solid molybdenum phases were identified by transmission electron microscopy. Molybdenum(VI) reduction by D. desulphuricans in the presence of sulphide caused the mineral molybdenite to precipitate. Reduction did not occur in the absence of an electron donor or in the presence of heat-killed cells of D. desulphuricans. Attempts to grow the bacterium with molybdenum(VI) as the sole electron acceptor were unsuccessful. Direct chemical reduction of molybdenum(VI) by sulphide or hydrogen also failed. Desulphovibrio vulgaris reduced molybdenum(VI) to molybdenum(IV) equally effectively. The work indicated that the enzymatic reduction of molybdenum(VI) by sulphate-reducing bacteria might contribute to the accumulation of molybdenum(IV) in anaerobic environments.

Special seals were developed to introduce the gas under pressure. Gas flows were induced in a wide range by using seals of various sizes. The apparatus was computer controlled. Permeability was calculated from seal geometry, gas flow rate, injection pressure, barometric pressure and gas temperature by a modified form of Darcy's law. The precision and consistency of measurements were evaluated from data collected from Berea sandstone and 2 synthetic rocks, all relatively homogeneous. The measurement error was consistent, amounting to about 1 per cent of the permeability. Measurements made at different volumes of rock effectively influenced by gas flow were free from systematic bias. Data sets were collected with 4 different-sized tip seals from the Berea sandstone to confirm the ability of the method to quantify upscaling processes. Distinct and consistent trends diagnostic of permeability upscaling relating the sample mean, variance and semivariogram to increased permeated rock volume were revealed by analysis.

The diffusion of the 3 analytes through a polydimethylsiloxane film was modelled by Fickian diffusion to fit the EFOCS data. To accurately model the data, inclusion of an interfacial conductance term, defined as the ratio of the mass transport coefficient across the polymer surface to the analyte diffusion coefficient in the polymer, was required. The interfacial conductance terms for the 3 analytes were of the same order of magnitude, suggesting a constant transport mechanism. Partial least-squares and principal component regression algorithms were used to model the EFOCS response to aqueous mixtures of the analytes with individual concentrations of 20 to 300 ppm. The algorithms performed comparably on the calibration sets, with cross-validated root-mean-squared errors of prediction for trichloroethylene, 1,1,1-trichloroethane and toluene of 26, 29 and 22 ppm, respectively. The prediction model was successfully used to determine concentrations of the 3 analytes in an independent data set. There are 34 references.

This reduced the wasteful homogeneous oxidation of manganese(II) which gave little deposition on the media. The latter were first exposed to manganese(II) and oxidant in a stirred tank reactor then transferred to a recirculating flow fixed-bed to deposit additional coating. Media were rinsed and the amount of deposited manganese oxides analysed. Media surfaces were examined by electron microscopy and surface areas quantified by cryogenic nitrogen adsorption. Anthracite pretreated with tin(II) chloride developed manganese oxide coatings up to 30 um thick at loadings of 4 mg extractable manganese per g. The efficient manganese(II)-removing capability of the media was confirmed in adsorption and oxidation modes at pH 6.0-7.5. The coating could also coprecipitate other trace elements.

It incorporated a modified Gnielinski mass transfer correlation for boundary layer transport, hydrodynamic dispersion, the Freundlich isotherm and a modified Keinath correlation for intracoating surface diffusion. The available fraction of equilibrium sorption capacity was the calibration parameter used for the sorptive process mode. For continuous regeneration by free chlorine, the sorbed manganese(II) oxidation rate constant was an additional calibration parameter and the 2 parameters were uncorrelated. The calibrated model predicted laboratory column effluent profiles under dynamic influent boundary conditions of sorption followed by desorption for ranges of pH, flow, ionic strength and calcium concentration. The model also satisfactorily accounted for oxidative manganese(II) removal for a range of process conditions for both synthetic and naturally coated media. Model structure was suggested by results of fundamental physical and chemical characterization of filter media from water treatment plants.

Two types of simulation were carried out: that of flow and tracer transport through heterogeneous flat-lying media; and simulation through dipping layered anisotropic media. Recharge inferred from environmental tracer methods proved highly spatially variable and estimates obtained from tracer profiles tended to overestimate recharge. Accuracy within a factor of 3-4 was possibly the best obtainable. Because sloping layered deposits added to the inaccuracy, hilltops, locations at slope bottoms, and slopes above 10 degrees were best avoided. Recharge estimates obtained from tracer profiles should therefore be critically evaluated with regard to the impacts of spatially variable flow. There are 40 references.

Most of the Cs is adsorbed on the basal surfaces (crystallite tops and bases) and on edge sites. Minor Cs may occur in defect expandable layers or substituting for K in illite layers. The (super 133) Cs NMR chemical shifts for Cs1 become more shielded (negative) as the Si/Al ratio of the substrate increases, whereas the shifts of Cs2 do not vary systematically with solid composition but are influenced by relative humidity and the Cs/H (sub 2) O ratio on the surface.

The remote site had very low levels of cultural noise, but strong winds (winter and spring) made the site an excellent candidate to study the effects of wind noise on seismograms. Along with a three-component set of surface sensors (Teledyne Geotech GS-13), a vertical borehole seismometer (GS-28) was deployed at a variety of depths (5, 43, and 85 m) to investigate signal and noise variations. Wind speed was measured with an anemometer. Event-triggered and time-triggered data streams were recorded on a RefTek 72-02 data acquisition system located at the site. Our data show little cultural noise and a strong correlation between wind speed and seismic background noise. The minimum wind speed at which the seismic background noise appears to be influenced varies with depth; 3 m/sec at the surface, 3.5 m/sec at 43 m in depth, and 4 m/sec at 85 m in depth. For wind speed below 3 to 4 m/sec, we observe omni-directional background noise that is coherent at frequencies below 15 Hz. This coherence is destroyed when wind speeds exceed 3 to 4 m/sec. We use a test event (M (sub d) approximately 1.6) and superimposed noise to investigate signal-to-noise ratio (SNR) improvement with sensor depth. For the low Q valley fill of the Datil borehole (DBH) site, we have found that SNR can be improved by as much as 20 to 40 dB between 23 and 55 Hz and 10 to 20 dB between 10 and 20 Hz, by deploying at a 43-m depth rather than at the surface. At the surface, there is little signal above noise in the 23- to 55-Hz frequency band for wind speeds greater than 8 m/sec. Thus, high-frequency signal information that is lost at the surface can be recorded by deploying at the relatively shallow depth of 40 m. Because we observe only minor further reductions in seismic background noise (SBN) at deeper depths, 40 m is likely to be a reasonable deployment depth for other high-frequency-monitoring sites in similar environmental and geologic conditions.

While the sites are geologically distinct, the near-surface noise environments have many common features that we believe may be due in large part to the presence of a surficial layer of highly attenuative unconsolidated material at each site. Noise levels seen at or near the surface (5 m or less) are much higher (up to 30 dB) and much more variable (power range up to 44 dB) than those seen at depth (the smallest range was 9 dB for 1951 m at Amarillo). The greatest gains in noise level reduction are realized within the first 100 m and probably much shallower (< approximately 10 m). Regardless of the wind profile or local lithology, all sites show an excellent correlation between increased noise levels and higher wind speed, even at significant depths (367 m at Amarillo). Wind-generated noise is broadband (at least 15 to 60 Hz) and apparently nonlinear, increasing dramatically when a wind speed threshold is exceeded (3 to 4 m/sec within a few meters of the surface; as high as 8 m/sec at a depth of a few hundred meters). It is possible to be essentially completely shielded from the wind-generated component of seismic noise by deploying instruments at sufficient depth, but we observed this only for the two deepest deployments (1219 and 1951 m, both at Amarillo). Reducing the wind profile at the surface, however, can yield similar reductions for a much smaller cost. Cultural or "workday" noise, if present (depending on the remoteness of the site), is typically much weaker (to dB or less) than wind noise but may propagate very effectively to great depths and therefore could be of concern for very deep deployments where wind is not a factor.

The initiating tectonic events include both discrete faulting and distributed rock deformation developed through the repository and adjacent to it, as well as earthquake-induced ground motion and changes in tectonic stress at the site. The effects of these tectonic events include impacts on the engineered-barrier system, such as container rupture and failure of repository tunnels. These effects also include a wide range of hydrologic effects such as changes in pathways and flow rates in the unsaturated and saturated zones, changes in the water-table configuration, and in the development of perched-water systems. These scenarios are intended go guide performance-assessment analyses and to assist principal investigators in how essential field, laboratory, and calculational studies are used. This suite of scenarios will help ensure that all important aspects of the system disturbance related to a tectonic scenario are captured in numerical analyses. It also provides a record of all options considered by project analysts to provide documentation required for licensing agreement. The final portion of this report discusses issues remaining to be addressed with respect to tectonic activity.

The SD-9 drill hole is located in the northern part of the potential repository area. Quantitative and semiquantitative data are included in this report for cover recovery, rock-quality designation (RQD), lithophysal cavity abundance, and fracturing. These data are spatially variable, both within and among the major formational-level stratigraphic units. Nonwelded intervals in general exhibit higher recoveries and more intact (higher) RQD values than welded intervals. The most intact, highest-RQD materials encountered within the Topopah Spring belong to the lower 33.3 ft of the middle nonlithophysal zone. This report includes quantitative data for the framework material properties of porosity, bulk and particle density, and saturated hydraulic conductivity. Graphical analysis of variations in these laboratory hydrologic properties indicates first-order control of material properties by the degree of welding and the presence of zeolite minerals. Many major lithostratigraphic contacts are not well expressed in the material-property profiles; contacts of material-property units are related more to changes in the intensity of welding. Approximate in-situ saturation data of samples preserved immediately upon recovery from the hole are included in the data tabulation.

The data used to model the thermal and mechanical behavior of the repository and surrounding lithologies include dry and saturated bulk densities, average grain density, porosity, compressional and shear wave velocities, elastic moduli, and compressional and tensional fracture strengths. In this study, a suite of experiments was performed on cores recovered from boreholes UE25 NRG-2, 2A, 2B, and 3 drilled in support of the Exploratory Studies Facility (ESF) at Yucca Mountain. The holes penetrated the Timber Mountain tuff and two thermal/mechanical units of the Paintbrush tuff. The thermal/mechanical stratigraphy was defined by Ortiz to group rock horizons of similar properties for the purpose of simplifying modeling efforts. The relationship between the geologic stratigraphy and the thermal/mechanical stratigraphy for each borehole is presented. The tuff samples in this study have a wide range of welding characteristics (usually reflected in sample porosity), and a smaller range of mineralogy and petrology characteristics. Generally, the samples are silicic, ash-fall tuffs that exhibit large variability in their elastic and strength properties.

Measurements have been performed on three thermal/mechanical units, PTn, TSwl, and TSw2. On each specimen the following bulk properties have been reported: dry bulk density, saturated bulk density, average grain density, and porosity. Unconfined compression to failure, confined compression to failure, and indirect tensile strength tests were performed on selected specimens recovered from the boreholes. In addition, compressional and shear wave velocities were measured on specimens designated for unconfined compression and confined compression experiments. Measurements were conducted at room temperature on nominally water-saturated specimens. The nominal rate for the fracture experiments was 10 (super -5) s (super -1) .

TEVES is a remediation demonstration that seeks to enhance an existing technology (vacuum extraction) by adding a new technology (soil heating). A pilot scale unit was set up at one of the organic waste disposal pits at the Sandia National Laboratories Chemical Waste Landfill (CWL) in Tech Area 3. The responsibility for engineering a major part of the process instrumentation for TEVES belonged to the Manufacturing Control Subsystems Department. The primary mission of the one-of-a-kind hardware/software system is to perform on-site gas sampling and analysis to quantify a variety of volatile organic compounds (VOCs) from various sources during TEVES operations. The secondary mission is to monitor a variety of TEVES process physical parameters such as extraction manifold temperature, pressure, humidity, and flow rate, and various subsurface pressures. The system began operation in September 1994 and was still in use on follow-on projects when this report was published.

Observed wave field complexities are dominated by coherent arrivals between direct S (or sS) and the core-reflected ScS (or sScS) phases. A relative waveform inversion method is used to objectively extract the time and amplitude of the three main spikes in each wavetrain, removing the effects of source time function, receiver, and instrument responses. The timing of the intermediate arrivals relative to S or ScS is used to define the volumetric position of scattering ellipsoids in the lower mantle, with intersections of ellipsoids illuminating possible regions of isotropic scattering. While a complete waveform migration is not viable due to the very limited ray path coverage and the band-limited data, the kinematics and relative amplitudes of the scattered arrivals are still valuable for assessing the origin of the waveform complexity. In this region, which displays particularly uniform existence of an extra arrival in the data, the simplest interpretation is that a scattering surface with lateral dimensions exceeding 1500 km at a depth near 2600 km in the mantle is responsible for the extra phase. This is consistent with previous interpretations involving a one-dimensional model with a rapid shear velocity increase or discontinuity 240-280 km above the core-mantle boundary. The proposed methodology can potentially image both heterogeneities or layering in the D" region as well as scattering from midmantle structure, although data limitations will continue to be a major obstacle.

On surfaces, PDFs appear as narrow (50-500 nm) lamellae filled with amorphosed quartz (diaplectic glass) which can be etched with hydrofluoric acid or with hydrothermal alkaline solutions. In contrast, slow-strain-rate tectonic deformation pressure produces wider, semi-linear and widely spaced arrays of dislocation loops that are not glass filled. Etching samples with HF before examination in a scanning electron microscope (SEM) allows for unambiguous visual distinction between glass-filled PDFs and glass-free tectonic deformation arrays in quartz. This etching also reveals the internal "pillaring" often characteristic of shock-induced PDFs. This technique is useful for easily distinguishing between shock and tectonic deformation in quartz, but does not replace optical techniques for characterizing the shock features.

However, since different structures impose fracture-forming stresses onto the strata in different ways, significantly different fracture intensities and patterns may be produced in different settings. Moreover, not all fractures of a given set are equal in length, aperture, or height (and therefore in their effect on permeability or seismic signal), even if they formed in the same stress regime: The range of apertures or lengths within a fracture set, for example, may consist of numerous narrow and/or short fractures and a few wide, long ones. This paper briefly discusses "regional" fractures, fractures that are common as relatively regular, extensive, parallel to subparallel features over wide areas within relatively undeformed strata (Figure 1).

Fracture characteristics were obtained from outcrop studies of Frontier sandstones at locations in the basin. The fracture data were combined with matrix permeability data to compute an anisotropic horizontal permeability tensor (magnitude and direction) corresponding to an equivalent reservoir system in the subsurface using a computational model. This analysis shows that the maximum and minimum horizontal permeability and flow capacity are controlled by fracture intensity and decrease with increasing bed thickness. The relationship between bed thickness and the calculated fluid-flow properties was used in a reservoir simulation study of vertical, hydraulically-fractured and horizontal wells and horizontal wells of different lengths in analogous naturally fractured gas reservoirs. The simulation results show that flow capacity dominates early time production, while storage capacity dominates pressure support over time for vertical wells.

This demonstration plan presents information on the EMWD-GRS technology, demonstration design, Cs-137 contamination at the Savannah River Site F-Area Retention Basin, responsibilities of demonstration participants, and the policies and procedures for the demonstration to be conducted at the Savannah River Site F-Area Retention Basin. The EMWD-GRS technology demonstration consists of continuously monitoring for gamma-radiation contamination while drilling two horizontal boreholes below the backfilled retention basin. These boreholes pass near previously sampled vertical borehole locations where concentrations of contaminant levels are known. Contaminant levels continuously recorded by the EMWD-GRS system during drilling are compared to contaminant levels previously determined through quantitative laboratory analysis of soil samples.

AN - 52834119; 1996-047077 AB - Vertical core, from relatively undeformed Cretaceous (Frontier Fm) sandstones at a depth of 18,300 ft in the Green River Basin, contains three sets of mineralized natural fractures. The earliest fractures opened in extension as the strata passed through the hydrocarbon window. Continued subsidence and the maturation of organic material created overpressured conditions, causing oil to be injected into the fractures. Only a carbon residue of the original oil remains in these fractures, suggesting continued burial and maturation. The residue seriously inhibits permeability along and across fractures. Oil residue is also present in oblique, unmineralized mare's-tails at the ends of fractures, suggesting that the in situ stress orientations had changed slightly. Quartz crystals mineralized the fracture walls, growing over the oil residue or pushing it aside. A second set of extension fractures strikes 20-30 degrees oblique to the first set. These fractures are mineralized with calcite, which was also deposited over the quartz in the first fracture set. Continued tectonism reoriented the horizontal stresses by nearly 90 degrees, forming a third set of extension fractures and further degrading permeability by narrowing apertures along earlier fractures. Significant porosity remains along many of the fractures at this depth, yet the in situ stresses and oil residue have combined to degrade fracture permeability to uneconomic matrix values.

Soil-water chemistry and isotopic data are presented from three deep vadose zone boreholes (>230 m) at the Nevada Test Site, located in the Great Basin geographic province of the southwestern United States, to quantify soil-water flux and its relation to climate. The low water contents found in the soils significantly reduce the mixing of tracers in the subsurface and provide a unique opportunity to examine the role of climate variation on recharge in arid climates. Tracing techniques and core data are examined in this work to reconstruct the paleohydrologic conditions existing in the vadose zone well beyond the timescales typically investigated. Stable chloride and chlorine 36 profiles indicate that the soil waters deep in the vadose zone range in age from approximately 20,000 to 120,000 years. Secondary chloride bulges that are present in two of the three profiles support the concept of recharge occurring at or near the last two glacial maxima, when the climate of the area was considerably wetter and cooler. The stable isotopic composition of the soil water in the profiles is significantly more depleted in heavy isotopes than is modern precipitation, suggesting that recharge under the current climate is not occurring at this arid site. Past and present recharge appears to have been strongly controlled by surface topography, with increased incidence of recharge where runoff from the surrounding mountains may have been concentrated. The data obtained from this detailed drilling and sampling program shed new light on the behavior of water in thick vadose zones and, in particular, show the sensitivity of arid regions to the extreme variations in climate experienced by the region over the last two glacial maxima.

However, under some hypothetical accident conditions, plutonium might be dispersed to the environment. This would result in costs being incurred by the government to remediate the site and compensate for losses. This study is a multi-disciplinary evaluation of the potential scope of the post-accident response that includes technical factors, current and proposed legal requirements and constraints, as well as social/political factors that could influence decision making. The study provides parameters that can be used to assess economic costs for accidents postulated to occur in urban areas, Midwest farmland, Western rangeland, and forest. Per-area remediation costs have been estimated, using industry-standard methods, for both expedited and extended remediation. Expedited remediation costs have been evaluated for highways, airports, and urban areas. Extended remediation costs have been evaluated for all land uses except highways and airports. The inclusion of cost estimates in risk assessments, together with the conventional estimation of doses and health effects, allows a fuller understanding of the post-accident environment. The insights obtained can be used to minimize economic risks by evaluation of operational and design alternatives, and through development of improved capabilities for accident response.

In this process, the ground is electrically heated, and borehole(s) within the heated zone are maintained at a vacuum to draw air and evaporated contaminants into the borehole and a subsequent treatment facility. TOUGH2 simulations have been performed to evaluate the fluid flow and heat transfer behavior of the system. The TOUGH2 version used in this study includes air, water, and a single-component non-aqueous phase liquid (NAPL). In the present simulations, an initial o-xylene inventory is assumed in the heated zone for illustration purposes. Variation in borehole (vapor extraction) vacuum, borehole location, and soil permeability were investigated. Simulations indicate that the temperatures in the soil are relatively insensitive to the magnitude of the borehole vacuum or the borehole locations. In contrast, however, the NAPL and liquid water saturation distributions are sensitive to these borehole parameters. As the borehole vacuum and air flow rate through the soil decrease, the possibility of contaminant (NAPL) migration from the heated zone into the surrounding unheated soil increases. The borehole location can also affect the likelihood of contaminant movement into the unheated soil.

We review current understanding of the gravity fingering process as developed through linear stability analysis and laboratory experiments. With respect to many complicating factors inherent in the field, this understanding is deficient in determining the field conditions where gravity fingering can be expected and the behavior of the field-scale fingering process when it occurs. This deficiency is exemplified in the results we present of a field experiment conducted in a sandy alluvial deposit. While simple extrapolation of current understanding of the process predicted instability, fingers did not occur. To begin to understand the influence of complicating factors inherent in the field, we conducted several laboratory experiments that address three important complicating factors: uniform and non-uniform initial moisture content, media heterogeneity, and the presence of macropores and fractures. These factors can fundamentally alter the gravity fingering process, its scale of expression and, under many field conditions, suppress its occurrence entirely. While the significance of gravity fingering of water in a wettable vadose zone is still inconclusive, gravity fingering will likely play a significant role in water/NAPL (non-aqueous-phase liquid) or water/NAPL/air systems, as occur within the saturated and vadose zones, respectively, at many contaminated industrial sites. To demonstrate this role, the results of a simple experiment are presented. JF - Geoderma AU - Glass, R J AU - Nicholl, M J A2 - Steenhuis, Tammo S. A2 - Ritsema, Coen J. A2 - Dekker, Louis W.

The model includes the influence of gravity and is applicable in the quasi-static limit of infinitesimal flow rate where viscous forces are negligible with respect to gravity and capillary forces. The incorporation of gravity alone creates complicated, pore-scale gravity fingers. To properly model wetting fluid invasion where macroscopic gravity fingers form, we incorporate a pore-scale geometric capillary smoothing function we refer to as "facilitation." Facilitation models the physics of wetting fluid invasion of pores by modifying the capillary pressure required to fill a pore based on the number of adjacent necks connecting the pore to the invading wetting fluid. The wetting fluid invasion facilitation process creates compact clusters and macroscopic fronts in horizontal simulations and in combination with gravity, creates macroscopic, gravity fingers that are in qualitative agreement with physical experiments. The MIP model yields much different imbibition front structures than standard invasion percolation. For MIP, capillary fingering, capillary facilitation, and gravity fingering compete to determine the wetted network structure as a function of pore-size distribution.

The perception is that characterization and remediation of these contaminated sites will be too costly using currently available technology. Consequently, the DOE Office of Technology Development has funded development of a number of alternative processes for characterizing and remediating these sites. The former Feed-Materials Processing Center near Fernald, Ohio (USA), was selected for demonstrating several innovative technologies. Contamination at the Fernald site consists principally of particulate uranium and derivative compounds in surficial soil. A field-characterization demonstration program was conducted during the summer of 1994 specifically to demonstrate the relative economic performance of seven proposed advanced-characterization tools for measuring uranium activity of in-situ soils. These innovative measurement technologies are principally radiation detectors of varied designs. Four industry-standard measurement technologies, including conventional, regulatory-agency-accepted soil sampling followed by laboratory geochemical analysis, were also demonstrated during the program for comparative purposes. A risk-based economic-decision model has been used to evaluate the performance of these alternative characterization tools. The decision model computes the dollar value of an objective function for each of the different characterization approaches. The methodology not only can assist site operators to choose among engineering alternatives for site characterization and/or remediation, but also can provide an objective and quantitative basis for decisions with respect to the completeness of site characterization.

Visualization can be combined with laboratory studies, numerical modeling, and other types of analyses to solve complex reservoir problems. An example is an ongoing study of well failures in the diatomite reservoirs of California.

XPS spectra indicate that minerals without exchangeable cation sites have a tendency to sorb Cs on surfaces and along grain boundaries to up to 1 mol% Cs. Sorbed Cs occurs in reacted montmorillonite, kaolinite and corundum, but not in gibbsite. Significant Cs is bound in the interlayer sites of montmorillonite, and occurs in expandable sites in kaolinite (very small amount of smectite-like interlayers). (super 133) Cs MAS NMR is likely to be a useful probe of the presence and smaller charge of expandable layers in kaolinite. The Cs environments in montmorillonite and kaolinite are sensitive to humidity. For kaolinite, the (super 133) Cs chemical shift changes at low T and 100 humidity, indicating that the interlayer charge is small.

The SWHC task has as its objective the reduction of uncertainty about the rate and direction of groundwater flow in the SNL/NM/Kirtland Air Force Base (KAFB) area. The SFR project area is located along the southern boundary of SNL/KAFB. This project area was selected to provide site-specific information related to geology and groundwater hydrology within the Hubbell Spring/Tijeras/Sandia fault complex. Specific objectives included determining the depth to the Santa Fe Group/bedrock contact, the depth to the water table, and the hydrogeologic complexities related to faulting. This report is a basic data report from the first phase of field operations associated with the drilling, logging, completion, and development of South Fence Road Wells SFR-1D and SFR-1S, SFR-2, SFR-3D and SFR-3S, and SFR-4. These test/monitoring wells were installed as part of Sandia National Laboratories, New Mexico, Environmental Restoration Project.

Dolomite growth is considered from interfacial kinetics. It is proposed that one path for dolomite growth from low-T natural waters is through the initial adsorption of Mg sulphate complexes onto either growing dolomite crystals or rate-limiting dolomite nucleii. Field relations and homogeneous syntheses at 25-100 degrees C support this proposal and a mechanistic explanation for dolomite growth from sulphate-rich waters.

Previous versions of FMT simulated double-porosity transport in two dimensions on the continuum from advection- to diffusion-dominated, with a user-specified velocity field to allow double-porosity transport. However, aqueous density was assumed constant, and reactive minerals were assumed to occupy negligible volume. Both of these assumptions can be considered poor for evaporite systems, where large changes in porosity and aqueous density can result from high mineral solubilities. Further development of FMT has relaxed these restrictions, allowing aqueous density to vary with phase composition, and allowing void volume to change as minerals dissolve and precipitate. This paper describes the additional mathematical complexity and code modifications required to simulate such systems. The sensitivity of advection-dominated transport to these variables is explored briefly in a one-dimensional example. JF - Journal of Contaminant Hydrology AU - Novak, Craig F A2 - Kim, J. I.

Such systems are being developed to monitor the effects of strain on geomembranes including the location of tears. Other possible measurements utilize moisture and fluid-level sensors. Since the use of geomembranes in geotechnical and environmental applications is widespread and monitoring systems are generally lacking, the potential for this technology is significant. For example, a geomembrane-and-sensor system addresses the need to monitor landfill stabilization in general and specifically the behavior of geomembranes used in liner and cover designs. We have demonstrated that glass and plastic fibers can be attached to a geomembrane (1) during extrusion and lamination and (2) by hot shoe welding, glued tape runners, and welded runners. Using these methods, we have manufactured 30 m lengths of geomembrane with continuous optical fiber across the length. Our preliminary focus has been on strain sensors to monitor landfill subsidence. We have utilized existing and newly developed strain sensors, e.g., microbend, Bragg grating, and adsorption band sensors. These sensors have been installed as arrays into several test membranes at a manufacturing scale (e.g., 3 to 4 m wide). The prototype monitoring systems were installed in laboratory test frames, and the sensors measured the strains across the membranes as they were loaded. We plan to scale these experiments up to the size of landfill cover system using a test cell under construction.

The pH of drainage from the waste rock pile at the unit ranges from 3 to 5. The drainage contains zinc (thousands of ppm), aluminum (hundreds of ppm), and copper and lead (tens of ppm). The acidic polluted water drains over a calcareous conglomerate into the Pecos River. Over the course of the drainage path, the pH increases to 7 and heavy metal content decreases to concentrations typical of the Pecos River upstream of the unit. Hydrous ferric oxides (HFOs) form around seep outlets and along the drainage channels. Hydrous aluminum oxides (HAOs) precipitate along the reach as white amorphous suspended gels. The main controls on pH of the drainage are the dissolution of calcite and dilution by tributaries. As pH increases, heavy metal concentrations attenuate by combined processes of mineral precipitation and sorption on to newly formed solids (coprecipitation). We used reaction modeling techniques to investigate the factors controlling heavy metal mobility in this system. We tested the roles of calcite dissolution and dilution by local ambient water. Over the course of these reaction paths, pH increases and iron and aluminum precipitate as HFOs and HAOs. Little HFO forms and therefore sorption on to this solid can not alone explain heavy metal attenuation. Adsorption to HAOs may play a more significant role. We constructed a modified double layer model for HAOs similar to that developed by Dzombak and Morel (1990) for HFOs. Modeling results suggest that although coprecipitation with aluminum oxides occurs, the primary control on metal mobility is direct precipitation of mineral phases.

These simulations provide conceptual insight into a number of hydrologic processes that are believed to play an important role in the post-Pleistocene hydrogeology of the southwestern United States. The simulated area covers 6000 square kilometers of a northern portion of the Delaware Basin. The stratigraphic interval considered comprises clastics and evaporites of Permian and Triassic age that overlie the Salado Formation. Physiographically, the area is on the western edge of the High Plains. Groundwater flow was simulated over the past 14,000 years to examine the hydrologic response to a drying of the climate in this region at the end of the Pleistocene. These simulations suggest that groundwater flow in this region is transient due to post-Pleistocene changes in climate. Change of hydraulic head with time in confined units reflects both a decrease in recharge at the end of the Pleistocene as well as Holocene wet-and-dry cycles. Hydraulic heads are not in equilibrium with either the modern-day recharge rate or the modern-day position of the water table. Groundwater basins in this region were less extensive during the wetter Pleistocene when the shape of a higher water table was defined by local topographic features rather than the regional topographic slope. The maximum long-term rate of recharge is this region is less than 2 mm/yr.

Transport equations are solved with a hybrid Lagrangian-Eulerian finite element method and include terms for advection, dispersion, diffusion, sources/sinks, colloid transport and mass production/reduction due to chemical reactions. Although flow equations are not solved by LEHGC, steady-state or transient flow fields for saturated or unsaturated flow in porous or fractured media can be used in LEHGC simulations. The chemical reactions considered are aqueous complexation, multi-site surface complexation, multi-site ion exchange, and precipitation-dissolution. The transport and geochemical equilibrium equations are separated into two subsystems which are solved in an iterative fashion. A massively-parallel version of LEHGC was produced to exploit this structure by solving the chemical equilibrium equations on multiple processors. Benchmark calculations on the 1824 node Intel Paragon computer showed speedup of nearly two orders of magnitude compared to a single-processor SPARC workstation. The current version of the software, LEHGC1.1, is the third generation in a series of codes developed in support of several NRC and DOE waste management programs. Partial verification of the code was accomplished under the O.E.C.D. CHEMical VALidation program. Examples of ongoing development and applications of the code will be presented. These include migration of uranium from remediated mill tailing sites, brine mixing and radionuclide transport.

Spatial scales associated with this problem vary from meters to kilometers with temporal scales from months to tens of thousands of years. Because such scales often preclude direct physical exploration of system response and detailed site characterization, we are forced to use our understanding (or misunderstanding) of the underlying physical processes to predict large scale behavior. For this reason, it is essential that conceptual models used as the basis for prediction be firmly grounded in physical reality.Over the past several years, we have performed experimental studies focused on understanding small-scale flow processes within discrete fractures and individual matrix blocks; much of the understanding gained from those experiments differs from that underlying the basic assumptions used in effective media representations. Here we synthesize the process level understanding gained from our laboratory studies to explore how such small-scale processes may influence the behavior of fluid flow in fracture networks and ensembles of matrix blocks at levels sufficient to impact the formulation of intermediate-scale effective media properties. We also explore how these same small-scale processes could couple to produce a large-scale system response inconsistent with current conceptual models based on continuum representations of flow through unsaturated, fractured rock. This large scale system behavior is, however, consistent with emerging geochemical data obtained from Yucca Mountain that suggests deep localized penetration of water. Based on our findings, a number of modifications to existing dual permeability models are suggested that should allow them improved applicability; however, even with these modifications, it is likely that continuum representations of flow through unsaturated fractured rock will have limited validity and must therefore be applied with caution.

Living, thermophylic, FeIII reducing and fermenting bacteria were retrieved from gas-bearing sandstone cores taken at ca. 860 m and 2,000 m below the surface. The Wasatch comprises the Atwell Gulch, Molina and the Shire Gulch; the microbes were retrieved from the Molina Member. The Atwell and Shire Gulch members are fluvial deposits dominated ( approximately 90%) by largely nonfractured mudstones. The Molina Member is sedimentologically variable but mainly is a more sandy facies with flashy, parallel-bedded sandstones. Fracture characteristics were investigated across the entire surface outcrop area of the Wasatch at a grid-spacing of 1 km. Two stress events affected these strata at different times, superimposing two oblique regional fracture sets on the clastic, fluvial lenses. A set of conjugate fractures is restricted to the Molina Member. Patterns of 2 overlapping sets of fractures in the Molina and related Wasatch sandstones/conglomerates were analyzed in detail at Rifle Gap, where the mudstones have been eroded away and the fluvial lenses are spectacularly exposed in a series of vertical ribs along the Grand Hogback. Fractures at Rifle Gap show an unsettling variability in orientation and sequence of formation that seem explainable only by the different fracture susceptibilities in the heterogeneous lithologies and the variable orientation of the high-aspect-ratio fluvial lenses relative to the overall stress fields that affected the basin.

Examination of core and shaft exposures has revealed that there are multiple scales of porosity within the Culebra including: fractures ranging from microscale to large, vuggy zones, and inter-granular porosity. A series of hydraulic and tracer tests has been conducted to evaluate the flow and transport properties of the Culebra. A primary objective of single-well injection-withdrawal and multiwell convergent-flow tracer tests was to evaluate whether there is significant solute diffusion from fractures into the rock matrix. To interpret tracer test results, numerical simulations have been conducted using single- and double-porosity models with homogeneous and heterogeneous hydraulic conductivity fields. Simulations to date indicate that it is not possible to model the single-well data without significant matrix diffusion. These simulations further suggest that both the single- and multiwell data cannot be adequately explained using a classical double-porosity model and heterogeneous permeability fields. However, an excellent fit to the single-well data can be obtained using a model that incorporates a statistical distribution of mass transfer rates (multirate diffusion). This distribution of effective diffusion rates represents variations in fracture spacing (surface area for diffusion and block size) and tortuosity of pores which is consistant with the observed scales of porosity.

It has been used for a series of sensor tests that have demonstrated the usefulness of the testbed. The facility consists of a cut-and-cover bunker complex and the two square mile surrounding area. The STF was developed as a scientific testbed optimized for the development and evaluation of advanced sensor systems, including ground sensor systems designed to identify and detect hardened underground facilities. This was accomplished by identifying a facility in a remote location where seismic, acoustic, and electromagnetic interference would be minimal, establishing a testbed that would be accommodating to field testing, and conducting a thorough geophysical characterization of the area surrounding the facility in order to understand the local geology and its effects on geophysical signals emanating from the facility. The STF is representative of a number of cut-and-cover bunkers around the world that are used for the manufacture and/or storage of weapons of mass destruction. This paper provides a general description of the Nevada Test Site, the Sensor Test Facility, and the Geophysical Site Characterization.

These holes were drilled to provide for geologic characterization of the Weeks Island Salt Dome and its overburden in the immediate vicinity of the sinkhole (mainly through logs and core); to establish a crosswell configuration for seismic tomography; to establish locations for hydrocarbon detection and tracer injection; and to Provide direct observations of sinkhole geometry and material properties. Specific objectives of the logging program were to: (1) identify the top of and the physical state of the salt dome; (2) identify the water table; (3) obtain a relative salinity profile in the aquifer within the alluvium, which ranges from the water table directly to the top of the Weeks Island salt dome; and (4) identify a reflecting horizon seen on seismic profiles over this salt dome. Natural gamma, neutron, density, sonic, resistivity and caliper logs were run.

A program has recently been initiated, under the auspices of the Advanced Computational Technology Initiative (ACTI), to achieve such a computational technology breakthrough by adapting the unique advanced quasistatic finite element technology developed by Sandia to the mechanics applications important to exploration and production activities within the oil and gas industry. As a precursor to that program, in an effort to evaluate the feasibility of the approach, several complex geologic structures of interest were analyzed with the existing two-dimensional quasistatic finite element code, SANTOS, developed at Sandia. Examples are presented and discussed.

They show that well damage and failures can occur under the action of two distinct mechanisms: shear deformations induced by pore compaction and subsidence, and shear deformations due to well-to-well interactions during production or water injection. They show such casting damage or failure can be localized to weak layers that slide or slip under shear due to subsidence. The magnitude of shear displacements and surface subsidence agree with field observations.

The approach used in this study is to combine experimental and numerical methods. Tests were conducted with an approximately 1/42 linear-scale mass-model of a 1/4 span section of a C-141 wing impacting a sand/clay mixture. The test results showed that within the uncertainty of the data, the percentage of incident liquid mass remaining in the crater is the same as that qualitatively described in earlier napalm bomb development studies. Namely, the percentage of fuel in the crater ranges from near zero for grazing impacts to 25%-50% for high angles of impact. To support a weapons system safety assessment (WSSA), the data from the current study have been reduced to correlations. The numerical model used in the current study is a unique coupling of a Smooth Particle Hydrodynamics (SPH) method with the transient dynamics finite element code PRONTO. Qualitatively, the splash, erosion, and soil compression phenomena are all numerically predicted. Quantitatively, the numerical method predicted a smaller crater cross section than was observed in the tests.

They also explore, by means of a thought experiment, how these same small-scale processes could couple to produce a large-scale system response inconsistent with current conceptual models based on continuum representations of flow through unsaturated, fractured rock. Based on their findings, a number of modifications to existing dual permeability models are suggested that should allow improved applicability.

A detailed geologic and hydrologic analysis was performed that accurately predicted the 3-dimensional plume configuration from a single point datum where significantly elevated contaminant levels were found in a bedrock core hole. Subsequent sampling found that direct discharges of contamination existed in the stream only in the location of the predicted stratum. The affected storm drain outfall discharges were suspected to be the major contributors to Sr-90 surface water risk from ORNL. Thus, the selected removal action focused on eliminating the known seepage to the storm drain network.

DNAPL is difficult to detect in the subsurface, much less characterize to any degree of accuracy. Without proper site characterization, remedial decisions are often difficult to make and technically effective, cost-efficient remediations are even more difficult to obtain. A new non-aqueous phase liquid (NAPL) characterization technology that is superior to conventional technologies has been developed and applied at full-scale. This technology, referred to as the Partitioning Interwell Tracer Test (PITT), has been adopted from oil-field practices and tailored to environmental application in the vadose and saturated zones. A PITT has been applied for the first time at full-scale to characterize DNAPL in the vadose zone. The PITT was applied in December 1995 beneath two side-by-side organic disposal pits at Sandia National Laboratories/New Mexico (SNL/NM) RCRA Interim Status Chemical Waste Landfill (CWL), located in Albuquerque, New Mexico. DNAPL, consisting of a mixture of chlorinated solvents, aromatic hydrocarbons, and PCE oils, is known to exist in at least one of the two buried pits. The vadose zone PITT was conducted by injecting a slug of non-partitioning and NAPL-partitioning tracers into and through a zone of interest under a controlled forced gradient. The forced gradient was created by a balanced extraction of soil gas at a location 55 feet from the injector. The extracted gas stream was sampled over time to define tracer break-through curves. Soil gas sampling ports from multilevel monitoring installations were sampled to define break-through curves at specific locations and depths. Analytical instrumentation such as gas chromatographs and a photoacoustical analyzers operated autonomously, were used for tracer detection.

On one hand, environmental decision makers do not have unlimited resources that they can apply to come to resolution on outstanding and uncertain technical issues. On the other hand, because of the possible impending consequences associated with these types of systems, avoiding making a decision is usually not an alternative either. Therefore, a structured, quantitative process is necessary that will facilitate technically defensible decision making in light of both uncertainty and resource constraints. An environmental decision support framework has been developed to provide a logical structure that defines a cost-effective, traceable, and defensible path to closure on decision regarding compliance and resource allocation. The methodology has been applied effectively to waste disposal problems and is being adapted and implemented in subsurface environmental remediation problems.

In a human intrusion scenario, actinide-bearing colloidal particles may be released from the repository and be transported by brines (approximately 0.8 to 3 molal ionic strength) through the Culebra, a thin fractured microcrystalline (mean grain size 2 micrometers) dolomite aquifer overlying the repository. Transport experiments were conducted using sieved, uniformly packed crushed Culebra rock or nonporous dolomite cleavage rhombohedra. Experiments with mineral fragments and fixed and live WIPP-relevant bacteria cultures showed significant levels of retardation due to physical filtration effects. Humic substances were not attenuated by the Culebra dolomite. Comparison of elution curves of latex microspheres in columns prepared with microcrystalline rock and nonporous rock showed minimal effect of Culebra micropores on colloid transport. These data form part of the basis to parameterize numerical codes being used to evaluate the performance of the WIPP.

Some heterogeneous formations may even have entirely different fracture sets within different layers, making exact predictions of fracture orientations in the subsurface even more difficult. An example of this is the basal Wasatch Formation in the Piceance Basin of western Colorado. Two stress events affected these strata at different times, superimposing two oblique regional fracture sets on many of the clastic, fluvial lenses. However, some beds fractured during the early stress event but were not susceptible during later stresses, whereas other beds did not fracture until the later event and contain fractures with entirely different orientations. Some beds contain both fracture sets and display obvious older-younger age relationships. The differences in fracture susceptibility that are caused by variable lithologies (and thus mechanical properties), can have significant influence on the fracture character of a reservoir. In the case of the Wasatch Formation, conglomerates were resistant to fracturing during the early stress event and thus contain only the later fractures, whereas sandstones commonly contain both sets. Fracture character may even change locally within a bed as the lithology changes from a pebble conglomerate at the base of a fluvial channel to a sandstone in higher zones.

AN - 50938240; 1997-017588 AB - The Molina Member of the Wasatch Formation is a primary objective for tight gas sandstone production. The G-Sandstone unit of the Molina produces an average of 200 MCFGPD. The chert-rich sandstones and conglomerates of the Molina Member, which are exposed in two subparallel belts on the western and eastern sides of the basin, are strikingly different from the remainder of the Wasatch Formation. The underlying Atwell Gulch Member and overlying Shire Member are composed of floodplain mudstones with well developed paleosols and rare, lenticular channel sandstones. Both units are interpreted as anastomosed fluvial deposits. The Molina Member, which varies from 32-118 m thick and in places contains clasts >0.2 m, is more difficult to interpret. Different portions of individual sections contain significant proportions of parallel laminated sandstones up to 5 m thick and several hundred meters wide. These parallel laminated sandstones are most common to the north along the western outcrop belt. They are interbedded with sandstones and conglomerates that are typical of a braided fluvial deposit. The contact between the two fluvial styles is sharp but conformable. The Molina Member therefore represents a perturbation in fluvial style from suspended-load to bedload and back to suspended-load over a restricted time interval. This may be the product of a change in climate, i.e., a change in rainfall amount or timing in the source area, source rock, e.g., the unroofing of a Jurassic eolian sandstone, or an increase in the depositional slope due to uplift. The return to a mud-dominated depositional system in the Shire Member argues for either climatic or source-rock variations as the primary control of the fluvial style.

The Sulphur Springs area, near the western margin of the resurgent dome, was the site of the earliest intensive exploration for geothermal resources in the caldera. In an earlier study we demonstrated that the conductive heat flow near the western margin of the Valles caldera averages between 300 and 400 mW m (super -2) . A combined total of 150 determinations of thermal conductivity on core segments from research wells VC-1, VC-2A, and VC-2B are sufficient to characterize the thermal conductivity of the major rock types in the area. A high degree of alteration of tuffs from VC-2A and VC-2B relative to VC-1 is reflected by significantly higher thermal conductivities, generally greater than 2 W m (super -1) K (super -1) , for the tuffs in the VC-2 wells relative to an average tuff conductivity of 1 W m (super -1) K (super -1) for VC-1. Temperature data from VC-2A and VC-2B confirm surface indications that the Sulphur Springs area is the locus of vigorous hydrothermal activity. The hydrothermal systems in both wells are capped by relatively thin (12 and 200 m, respectively) near-surface conductive thermal regimes. Heat flows from these near-surface caps are 7200+ or -370 mW m (super -2) (+ or -standard error) for VC-2A and 1340+ or -60 mW m (super -2) for VC-2b, several times the very high background heat flux in the western portion of the caldera of 250 to 350 mW m (super -2) . The probable source of these high heat-flow values is the intrusion of one or more shallow magma bodies during the post-collapse history of the caldera.

A hydraulic testing program was conducted at the WIPP site from 1988 to 1995 to develop an understanding of flow through evaporites and quantify important hydrogeologic parameters. Testing and analytical approaches increased in complexity and sophistication as the program evolved, reflecting increased knowledge of the difficulties involved in definitive testing of low-permeability strata. Initially, the testing program relied on pressure-pulse tests, also known as shut-in slug tests, to estimate formation permeability and pore pressure. The first problem encountered was that the compressibility within the test interval, initially assumed to be that of water, appeared to be both significantly higher than that of water and not constant during tests. Subsequent testing focussed on this problem showed that test-zone compressibility represents the aggregate compressibility of all materials within a test zone; is a function of test-zone pressure (decreasing by several orders of magnitude as pressure increases from 0 to 3 or more MPa); and is always higher than the compressibility of water. Thus, test-zone compressibility must be measured over the range of pressures expected during a hydraulic test. The time required to test low-permeability media was underestimated. Definitive testing of a medium with a hydraulic diffusivity of 10 super(-6) m super(2)/s or less (hydraulic conductivity less than or equal to 10 super(-13) m/s) can take a year or more to complete. Measures found to reduce testing time included: 1) completing drilling and tool installation as rapidly as possible to reduce the pressure transient caused by those activities; 2) artificially raising the test-zone pressure to the predicted formation pore pressure immediately after shut in; and 3) designing test tools to minimize the fluid volume in the test zone. Pressure-pulse tests were also found to be too sensitive to wellbore storage and skin to allow definitive interpretation. Therefore, the program scope was expanded to include constant-pressure flow tests followed by pressure-buildup tests. Having data from the three different types of tests proved to be highly useful in constraining interpretations. Constant-pressure flow tests were found to be operationally easier to perform than constant-rate flow tests in media in which typical flow rates may be less than or equal to 10 cm super(3)/day. Cross-hole tests were performed in a few cases over distances of a few meters, but such tests are rarely practical in low-permeability media because of the long time required to propagate a pressure transient between holes and overcome wellbore storage in the observation hole. Other operational difficulties included temperature changes causing pressure changes, gas exsolving from solution as borehole pressures were decreased, borehole elongation during testing due to salt creep, and extremely high pressure gradients. Low-permeability media can maintain pressure gradients around excavations far in excess of normal gradients in undisturbed rock. Pore pressures of 12 MPa have been observed within 11 meters of WIPP excavations, corresponding to hydraulic gradients of over 100 meters of head per meter distance. Even specially designed packers cannot sustain pressure differentials greater than about 8 MPa for long periods of time, which makes testing difficult in short holes drilled from an excavation with no column of drilling mud to balance the formation pressure. All of the non-ideal conditions encountered during testing necessitate the use of a sophisticated numerical model for test interpretation. A model has been developed that can incorporate pressure-dependent test-zone compressibility, temperature effects, volume changes, and complex pre-test conditions directly in test interpretation. The model performs automatic fitting of parameters in linear, log, and/or derivative space for individual tests or complete set sequences, and also provides correlated uncertainty estimates for all parameters.

Often, a lack of basic information on the chemical and physical characteristics of the soil and contaminants hampers treatability studies used to design these technologies. This article proposes and demonstrates a characterization program to meet these information needs, employing standard analytical techniques coupled with advanced spectroscopy and microscopy techniques. To support treatments involving physical separation strategies, the program uses standard analytical techniques to characterize the soil and the association of contaminants with different soil fractions (e.g., size and density fractions). Where chemical treatments are required, spectroscopy and microscopy methods are employed to yield quantitative information on the oxidation state and speciation of the contaminant. Examples demonstrate the use of measured soil and contaminant characteristics in the screening of alternative treatment technologies and in the selection of soils for use in treatability studies. Also demonstrated is the use of these characterization tools in the design and optimization of treatment strategies and in support of risk assessment determinations.

The instrument was designed to be permanently buried in intimate contact with the formation at the subsurface location where the measurement was to be made. Data could be collected remotely from the sensors during extended periods, provided electric power and telephone communications were accessible, with minimal intervention on site. Flow velocities ranging from 0.000005 to 0.001 cm per second could be measured, depending on the thermal properties of the medium.

Conversion of isopropyl alcohol to acetone AN - 13640319; 199702956 AB - Supercritical water oxidation is a promising technology for the destruction of hazardous organic waste streams, especially those containing a large aqueous fraction. The use of in situ Raman spectroscopy enabled the absolute concentration of reactants, intermediates and final products to be determined simultaneously. The investigation was carried out to obtain data for model validation, on the oxidation characteristics of isopropyl alcohol in supercritical water and to identify the reaction intermediates, as well as determining the effect of temperature on the oxidation rate of both isopropyl alcohol and acetone. A 6.1 weight per cent solution of hydrogen peroxide was used as the oxidant, plus a 1 weight per cent solution of isopropyl alcohol as the fuel. The system was calibrated for the 400-480C temperature range and a pressure of 24.4 MPa, with residence periods in the 0.56-2.41 second range. Acetone was found to be a key intermediate product in the oxidation process and first-order kinetics were assumed for the destruction of the isopropyl alcohol.

Flow velocity measurements obtained with the flow sensors were compared directly with velocities estimated using standard hydrological techniques. Two flow sensors were deployed in a confirmed aquifer near a well screened through the entire vertical extent of the aquifer. The well was pumped at 4 different pumping rates. The sensors could measure the local groundwater flow velocity vector quite accurately, but care was needed to disturb the formation as little as possible during emplacement.

Geostatistical framework AN - 13632831; 199702600 AB - A method of assessing the extent of groundwater contamination was formulated based on measured contaminant concentrations at a few locations and an assumption that the temporal changes occurring in the flow system were small compared with the time and spatial scales involved in the project. The method was based on the geostatistical technique of conditional simulation to generate a series of stochastic images, each portraying a plausible spatial distribution of contaminant concentrations across the site. The latter was discretized into an array of panels and a simulated contaminant level obtained for each panel. Probability maps were then created. These provided tools for estimating the plausible range of contaminant concentrations at unsampled locations, the identification of boundaries between contaminated and uncontaminated areas, and estimating the range of plausible values of total contaminant mass. The approach provided an assessment of groundwater pollution at waste sites that was cheaper and less time-consuming than other methods, although with a finite probability of classification errors.

The three dimensional flow velocity was recorded on an hourly basis from mid May to mid July, 1994 and for one week in September. The first data collection interval coincided with the seasonal high water level in the river while the second interval reflected conditions during relatively low seasonal river stage. Two flow sensors located approximately 50 feet from the river recorded flow directions which correlated very well with river stage, both on seasonal and diurnal time scales. The magnitudes of the flow velocities recorded by the flow sensors were lower than expected, probably as a result of drilling induced disturbance of the hydraulic properties of the sediments around the probes.

Seven advanced field-screening technologies were demonstrated at a uranium-contaminated site at Fernald, located 29 kilometers northwest of Cincinnati, Ohio. The seven technologies tested were: (1) alpha-track detectors, (2) a high-energy beta scintillometer, (3) electret ionization chambers, (4) and (5) two variants of gamma-ray spectrometry, (6) laser ablation-inductively coupled plasma-atomic emission spectroscopy, and (7) long-range alpha detection. The goals of this field demonstration were to evaluate the capabilities of the detectors and to demonstrate their utility within the US Department of Energy's Environmental Restoration Program. Identical field studies were conducted using four industry-standard characterization tools: (1) a sodium-iodide scintillometer, (2) a low-energy FIDLER scintillometer, (3) a field-portable x-ray fluorescence detector, and (4) standard soil sampling coupled with laboratory analysis. Another important aspect of this program was the application of a cost/risk decision model to guide characterization of the site. This document is a compilation of raw data submitted by the technologies and converted total uranium data from the 1994 Fernald field characterization demonstration.

Emphasis was first given to concrete and then expanded to include other materials. This report contains a summary of engineering and construction details of various sealing methods used by mining industries for bulkheads and shaft liners. Cases examined include successes and failures, and both contribute to a database of experiences. Mass salt-saturated concrete placement under ground was accomplished under several varied conditions. Information derived from this database has been used to assess the performance of concrete as a seal material.

LEHGC iteratively solves two-dimensional transport and geochemical equilibrium equations and is a descendant of HYDROGEOCHEM, a strictly Eulerian finite-element reactive transport code. The hybrid Lagrangian-Eulerian scheme improves on the Eulerian scheme by allowing larger time steps to be used in the advection-dominant transport calculations. This causes less numerical dispersion and alleviates the problem of calculated negative concentrations at sharp concentration fronts. The code also is more computationally efficient than the strictly Eulerian version. LEHGC is designed for generic application to reactive transport problems associated with contaminant transport in subsurface media. Input to the program includes the geometry of the system, the spatial distribution of finite elements and nodes, the properties of the media, the potential chemical reactions, and the initial and boundary conditions. Output includes the spatial distribution of chemical element concentrations as a function of time and space and the chemical speciation at user-specified nodes. LEHGC Version 1.1 is a modification of LEHGC Version 1.0. The modification includes: (1) devising a tracking algorithm with the computational effort proportional to N where N is the number of computational grid nodes rather than N (super 2) as in LEHGC Version 1.0, (2) including multiple adsorbing sites and multiple ion-exchange sites, (3) using four preconditioned conjugate gradient methods for the solution of matrix equations, and (4) providing a model for some features of solute transport by colloids.

Differences in the lithologic character of the rocks have been used to subdivide the rock sequence into stratigraphic units, and the deterministic nature of the processes responsible for the character of the different units can be used to infer the rock material properties likely to exist in unsampled regions. This report proposes a quantitative, theoretically justified method of integrating interpretive geometric models, showing the three-dimensional distribution of different stratigraphic units, with numerical stochastic simulation techniques drawn from geostatistics. This integration of soft, constraining geologic information with hard, quantitative measurements of various material properties can produce geologically reasonable, spatially correlated models of rock properties that are free from stochastic artifacts for use in subsequent physical-process modeling, such as the numerical representation of ground-water flow and radionuclide transport. Prototype modeling conducted using the GSLIB-Lynx Integration Module computer program, known as GLINTMOD, has successfully demonstrated the proposed integration technique. The method involves the selection of stratigraphic-unit-specific material-property expected values that are then used to constrain the probability function from which a material property of interest at an unsampled location is simulated.

The surface characteristics of corrensite, a mixed chlorite/smectite clay mineral, have been studied. Zeta potential measurements and titration experiments suggest that the corrensite surface contains a mixture of permanent charge sites on the basal plane and SiOH and AlOH sites with a net pH-dependent charge at the edge of the clay platelets. Triple-layer model parameters were determined by the double extrapolation technique for use in chemical speciation calculations of adsorption reactions using the computer program HYDRAQL. Batch adsorption studies showed that corrensite is an effective adsorbent for uranyl. The pH-dependent adsorption behavior indicates that adsorption occurs at the edge sites. Adsorption studies were also conducted in the presence of competing cations and complexing ligands. The cations did not affect uranyl adsorption in the range studied. This observation lends support to the hypothesis that uranyl adsorption occurs at the edge sites. Uranyl adsorption was significantly hindered by carbonate. It is proposed that the formation of carbonate uranyl complexes inhibits uranyl adsorption and that only the carbonate-free species adsorb to the corrensite surface. The presence of the organic complexing agents EDTA and oxine also inhibits uranyl sorption.

Two-dimensional channels were constructed with an idealized sinusoidal roughness on each wall. Flow in the channels was studied by both methods for various amplitude to wavelength ratios of the roughness, surface separations, relative alignment or phase of the sinusoids, and Reynolds numbers. The Reynolds equation overestimates fluid velocity as the surfaces are placed together or the amplitude of the roughness increases relative to its wavelength.

The experiment consisted of allowing water to evaporate from homogeneously packed sand columns and periodically sampling to observe changes in the distributions of moisture, temperature, and oxygen-18 enrichment. The peaks of the oxygen-18 distributions were used to determine the value of moisture content at liquid discontinuity, a parameter important for modeling water vapor flow. Modeling transient second-stage evaporation from soil necessitated implementing a retention relation Psi (theta ) that is applicable for dry soils, above the evaporation front, where vapor flow is dominant. A retention model for dry soils was developed, connected to the Van Genuchten model and the resulting two-segment retention relation was implemented in the numerical model. The connection point for the retention relation is the moisture content at liquid discontinuity, which was also used in the numerical model to locate the evaporation front. Simulations showed that the ODWISH model reproduces reasonably well the experimental distributions of moisture content, isotopic enrichment, and temperature, and that the model accounts for the major processes involved in water movement in the shallow unsaturated zone and the associated isotope transport. The most significant discrepancies between the simulations and the experimental data can probably be attributed to inadequencies of the available two-segment Psi (theta ) relationship over the wide range of pressure heads Psi encountered during the experiment. The ODWISH model was employed to test the sensitivity of the isotope profile development to diurnal variations in temperature and humidity.

The project, which was funded by the Strategic Environmental Research and Development Program (SERDP), involved the application of a geostatistical-based Adaptive Sampling methodology and software with on-site field screening of soils for radiation, organic compounds and metals. The software, known as Plume (super TM) , was developed at Argonne National Laboratory as part of the DOE/OTD-funded Mixed Waste Landfill Integrated Demonstration (MWLID). The objective of the investigation was to compare an innovative Adaptive Sampling approach that stressed real-time decision-making with a conventional RCRA-driven site characterization carried out by the Air Force. The latter investigation used a standard drilling and sampling plan as mandated by the Environmental Protection Agency (EPA). To make the comparison realistic, the same contractors and sampling equipment (Geoprobe (super R) soil samplers) were used. In both investigations, soil samples were collected at several depths at numerous locations adjacent to burial trenches that contain low-level radioactive waste and animal carcasses; some trenches may also contain mixed waste. Neither study revealed the presence of contaminants appreciably above risk based action levels, indicating that minimal to no migration has occurred away from the trenches. The combination of Adaptive Sampling with field screening achieved a similar level of confidence compared to the Resource Conservation and Recovery Act (RCRA) investigation regarding the potential migration of contaminants at the site.

The study area was Hualalai volcano, Hawaii, where chemically, temporally and mineralogically similar lava flows intersect isohyets which bend uphill to lower mean annual T. Along the 500 mm isohyet, 2000-2700 yr old basalt flows were sampled using plagioclase weathering rates. The natural T sensitivity of the plagioclase weathering has an activation energy of 26.2 kcal/mol. using this method, which is somewhat higher than solute-budget and laboratory measurements of plagioclase weathering. The method can quantify long-term (> 10 (super 5) yr) weathering by measuring the microscopic dissolution of minerals in outcrops.

To investigate matrix heterogeneity effects, we perform a simple experiment in which x-ray imaging is used to measure the imbibition of water from a flowing fracture into a slab of volcanic tuff. Experimental results show matrix imbibition to follow a linear t (super 1/2) relationship even though the saturated hydraulic conductivity of the tuff varies by over four orders of magnitude.

In the processes of imbibition and drainage, the connectivity of each phase at a particular capillary pressure can be sought out by the priority-first search algorithm of graph theory. Then, the flow path in each phase can be identified, and flow equations can be established and solved in an optimal manner. It was observed that in a simulated rough fracture, a few flow "channels" can dominate the permeability of the whole system. Copyright 1995 by the American Geophysical Union.

Updating the fields and Green's functions relates small changes in the predicted data to small changes in the model parameters through Frechet kernels. These fields and Green functions are calculated with an efficient 3-D finite-difference solver. Since the resistivity is invariant along strike, the 3-D fields are integrated along strike so the 2-D kernels can be assembled.At the early stages of the inversion, smoothing of the electrical conductivity stabilizes the inverse solution when it is far from convergence. As the solution converges, this smoothing is relaxed and more effort is made to reduce the data misfit. Bounds on the conductivity are included in the solution to eliminate unrealistic estimates.The robustness of the inversion scheme has been demonstrated with synthetic and field data that are underdetermined from the standpoint of the smooth models being sought. Two synthetic examples with added Gaussian noise were considered, including data arising from an IE solver. This IE solver is different from the one embedded in the inversion algorithm and has provided a stronger check on the scheme. The synthetic examples show it is more difficult to reconstruct a target's conductivity than its geometry at a single frequency. The inversion scheme has been successfully tested using data collected at the Richmond-field site near Berkeley, California, where it has imaged a salt water plume injected into the interwell region. The data in this experiment consisted of two sets of measurements, taken before and after the injection of 50000 gallons of 1 Omega m salt water. Findings show that underdetermined inversion using small amounts of field data can be sufficient to produce useful, but smoothed, maps of the conductivity. The data in this instance need be only single frequency and single component.

The fracture aperture field and phase occupancy were measured using light transmission techniques and then combined to calculate bulk water-phase saturation within the fracture as a function of time. Fracture relative permeability as a function of water-phase saturation showed a smooth power law behavior during dissolution. Periodic step pulses of clear water within the dyed water inflow yielded dye concentration fields that demonstrate channeling induced by the entrapped air phase. Clusters of the entrapped air-phase exhibited three types of dissolution behavior: general shrinkage, interfacial recession along cluster appendages, and cluster splitting. Locations for the advance of the wetting phase (water) into a nonwetting entrapped air cluster on its dissolution are not always correlated with either zones of high mass transfer rate (as inferred from gradients in the pulsed dye concentration fields) or with narrow apertures where the wetting phase has been thought to most easily invade. These results suggest that within an individual cluster of the entrapped phase, fluid pressure is at equilibrium and that the path of cluster shrinkage may be controlled primarily by capillary forces resulting from the full three-dimensional curvature that minimizes surface energy of the phase interface.

Data collected included ambient pressures, differential pressures between soil gas and ambient air, gas flow rates into and out of the soil, and concentrations of volatile organic compounds (VOCS) in vented soil gas. From the differential pressure and flow rate data, estimates of permeability were arrived at and compared with estimates from other studies. Flow, differential pressure, and ambient pressure data were collected for nearly 30 days. VOC data were collected for two six-hour periods during this time. Total VOC emissions were calculated and found to be under the limit set by the Resource Conservation and Recovery Act (RCRA). Although a complete process evaluation is not possible with the data gathered, some of the necessary information for designing a passive venting process was determined and the important parameters for designing the process were indicated. More study is required to evaluate long-term VOC removal using passive venting and to establish total remediation costs when passive venting is used as a polishing process following active soil vapor extraction.

Uranium usually exists in either the U(IV) or the U(VI) oxidation state. U(VI) is soluble in water and, as a result, is very mobile in the environment. U(IV), however, is generally insoluble in water and, therefore, is not subject to aqueous transport. In recent years, researchers have discovered that certain anaerobic microorganisms, such as the sulfate-reducing bacteria Desulfovibrio desulfuricans, can mediate the reduction of U(VI) to U(IV). Although the ability of this microorganism to reduce U(VI) has been studied in some detail by previous researchers, the kinetics of the reactions have not been characterized. The purpose of this research was to perform kinetic studies on Desulfovibrio desulficans bacteria during simultaneous reduction of sulfate and uranium and to determine the phase in which uranium exists after it has been reduced and precipitated from solution. The studies were conducted in a laboratory-scale chemostat under substrate-limited growth conditions with pyruvate as the substrate. Kinetic coefficients for substrate utilization and cell growth were calculated using the Monod equation. The maximum rate of substrate utilization (k) was determined to be 4.70 days (super -1) while the half-velocity constant (K (sub s) ) was 140 mg/l COD. The yield coefficient (Y) was determined to be 0.17 mg cells/mg COD while the endogenous decay coefficient (k (sub d) ) was calculated as 0.072 days (super -1) . After reduction, U(IV) Precipitated from solution in the uraninite (UO2) phase. Uranium removal efficiency as high as 90% was achieved in the chemostat.

This document reports on the results of a survey of data on the costs associated with significant natural disasters. There is an impressive amount of work and effort going into natural disaster research, mitigation, and relief. However, despite this effort, there are surprisingly few consistent and reliable data available regarding the effects of natural disasters. Even lacking consistent and complete data, it is clear that the damage and fatalities from natural disasters are increasing both in the United States and globally. Projections using the available data suggest that in the United States alone, the costs of natural disasters between 1995 and 2010 will be in the range of $90 billion (in 94$) and 5000 lives.

The four sources evaluated were the Bolt airgun, the OYO-Conoco orbital vibrator, and two Sandia-developed vertical vibrators, one pneumatically-driven, and the other based on a magnetostrictive actuator. The sources generate seismic energy in the lower frequency range of less than 1000 Hz and have different frequency characteristics, radiation patterns, energy levels, and operational considerations. Collection of identical data sets with all four sources allows the direct comparison of these characteristics and an evaluation of the suitability of each source for a given site and target.

A vector Helmholtz formulation for the electric fields is employed to avoid problems associated with the first order Maxwell's equations numerically decoupling in the air. Additional stability is introduced by formulating the problem in terms of the scattered electric fields which replaces an impressed dipole source with an equivalent source that possesses a much smoother spatial dependence and is easier to model. In order to compute this equivalent source, a primary field arising from dipole sources in a whole space must be calculated where ever the conductivity is different than that of the background. The Helmholtz equation is approximated using finite differences on a staggered grid. After finite differencing, a complex-symmetric matrix system of equations is assembled and preconditioned using Jacobi scaling before it is solved using the quasi-minimum residual (QMR) method. In order to both speed up the solution and allow for larger, more realistic models to be simulated, the scheme has been modified to run on massively parallel architectures. The solution has been compared against other 1-D and 3-D numerical models and is found to produce results in good agreement. The versatility of the scheme is demonstrated by simulating a survey over a salt water intrusion zone in the Florida Everglades.

They have improved sensitivity to the subsurface resistivity distribution because of the closer proximity to the area of interest offered by the borehole for the source or the receiver. For the borehole-to-surface measurements the source is in the borehole and the receivers are on the surface. On the other hand, for the surface-to-borehole methods, the source is on the surface and the receiver is in a borehole. The surface-to-borehole method has an added advantage since measurements are often more accurate due to the lower noise environment for the receiver. For these methods, the source can be a grounded electric dipole or a vertical magnetic dipole source. An added benefit of these techniques is field measurements are made using a variety of arrays where the system is tailored to the application and where one can take advantage of some new imaging methods. In this short paper we describe the application of the borehole-to-surface method, discuss benefits and shortcomings, and give two field examples where they have been used for underground imaging.

The oil is stored in an old salt mine located within a salt dome. In order to assess the hydrologic significance of the sinkhole, an In Situ Permeable Flow Sensor was deployed within a sandfilled conduit in the salt dome directly beneath the sinkhole. The flow sensor is a recently developed instrument which uses a thermal perturbation technique to measure the magnitude and direction of the full 3-dimensional groundwater flow velocity vector in saturated, permeable materials. The flow sensor measured substantial groundwater flow directed vertically downward into the salt dome. The data obtained with the flow sensor provided critical evidence which was instrumental in assessing the significance of the sinkhole in terms of the integrity of the oil storage facility.

This study indicates that interactions between organic acids and mineral surfaces may control Al transport during clastic diagenesis. Oxalate adsorption onto alumina (gamma -Al (sub 2) O (sub 3) ) was measured as a function of pH at 25 degrees and 60 degrees C in 0.1 M NaCl solutions. The thermodynamic stability of the surface Al-oxalate complex remains relatively constant with increasing temperature. Decreasing grain size amplifies the degree to which mineral surfaces control Al and oxalate concentrations through oxalate adsorption in fluid-rock systems. Therefore, diagenetic phase changes should be focused at discontinuities in mineral grain diameter. Furthermore, this grain size effect can influence aluminosilicate mineral solubilities and, therefore, may play an important role in determining the distribution and transport of Al and organic acid anions in sedimentary basins.

A conceptual model based on this mechanism suggests that regional fractures and the maximum horizontal compressive stress trajectories in the Frontier Formation in the central Green River basin trend approximately north-south. This regional pattern was produced by the transmission of stresses out into the basin from Sevier and Laramide thrusting at the edges of the basin. The Sevier thrust belt on the western margin of the basin was active for 100 million years, but had relatively little influence on stresses and fracturing in the Frontier Formation within the basin because stresses from this system were self-limiting. The relatively weak east-west horizontal stress trajectories from this system were overwhelmed by north-south compression during the Laramide orogeny. Stress and fracture orientations are expected to deviate from the general north-south trend at the basin margins, in the corners of the basin, and in association with local structures including the Moxa Arch. Finite-element modeling, and stress-orientation data from a limited number of oriented caliper logs, support the conceptual stress trajectories.

Drawing on the advice and assistance of the Project's principal investigators (PIs), a collection of release scenarios initiated by the nominal ground-water flow occurring in the vicinity of the potential Yucca Mountain high-level-waste repository is developed and described in pictorial form. This collection of scenarios is intended to provide a framework to assist PIs in recognizing essential field and calculational analyses, to assist performance assessment in providing guidance to site characterization, and to continue the effort to exhaustively identify all features, events, and processes important to releases.

An innovative aspect of this methodology is the generation of an ensemble of conditional simulations of the transmissivity field which preserve the statistical moments and spatial correlation structure of the measured transmissivity field and honors the measured transmissivity values at their locations. Each simulation is then calibrated, using an iterative procedure, to match an exhaustive set of steady state and transient pressure data. A fully automated inverse algorithm using pilot points as parameters of calibration was employed. The application of this new methodology to the Culebra dolomite flow system produced 70 conditional simulations which were consistent with all the measured transmissivity and head data at the site. Based on an analysis of the calibrated transmissivity fields, the spatial variability of the transmissivity fields was increased as a result of the calibration process. This increase is in part due to the addition of a high-transmissivity feature to each of the transmissivity fields which is needed to match both steady state and transient state head data.

The methodology addresses the issue of nonuniqueness of the inverse solutions by generating an ensemble of transmissivity fields considered to be equally likely, each of which is in agreement with the measured transmissivity and pressure data. It consists of generating a selected number of conditionally simulated transmissivity fields and then calibrating each of the fields to match the measured steady state or transient pressures, in a least squares sense. The calibration phase involves an iterative implementation of an automated pilot point approach coupled with conditional simulations. Pilot points are the parameters of calibration. They are synthetic transmissivity data which are added to the transmissivity database to produce a revised conditional simulation during calibration. Coupled kriging and adjoint sensitivity analysis is employed for the optimal location of pilot points, and gradient search methods are used to derive their optimal transmissivities. The pilot point methodology is well suited for characterizing the spatial variability of the transmissivity field in contrast to methods using zonation. Pilot points are located where their potential for minimizing the objective function is the highest. This minimizes the perturbations in the transmissivities which are optimally assigned to the pilot point and results in minimal changes to the covariance structure of the transmissivity field. The calibrated fields honor the transmissivity measurements at their locations, preserve the variogram, and match the measured pressures in a least squares sense. Since there are numerous options in the execution of this methodology, computational experiments have been conducted to identify the most efficient among them. The method has been applied to the Waste Isolation Pilot Plant (WIPP) site, in southeastern New Mexico, where the U.S. Department of Energy is conducting probabilistic system assessment for the permanent disposal of transuranic nuclear waste. The resulting calibrated transmissivity fields are input to a Monte Carlo analysis of the total system performance. The present paper, paper 1 of a two-paper presentation, describes the methodology. Paper 2, a companion paper, presents the methodology's application to the WIPP site. Copyright 1995 by the American Geophysical Union.

The analysis assumes steady infiltration and that the principal directions of the hydraulic conductivity tensor are parallel and normal to the fine-coarse contact. The solutions for divergence capacity and length have two terms. The first term, similar to the solution of Ross, represents the diversion due to the presence of the capillary barrier and is proportional to the hydraulic conductivity parallel to the contact. The second term, which arises from infiltration into an anisotropic medium independent of the capillary barrier, is a function of the fine layer thickness and will be small for engineered barriers. Thus an anisotropic fine layer with a greater hydraulic conductivity in the direction parallel to the fine-coarse contact will extend the performance of a capillary barrier as measured by its divergence capacity and length.

A general framework for validation and confidence building in regulatory decision making is provided. It is found that traditional validation studies have a very limited role in developing site-specific confidence in performance assessments. Indeed, validation studies are shown to have a role only in the context that their results can narrow the scope of initial investigations that should be considered in a performance assessment. In addition, validation needs for performance assessment of low-level waste disposal facilities are discussed, and potential approaches to address those needs are suggested.

Within the ER project, the site-wide hydrogeologic characterization task is responsible for the area-wide hydrogeologic investigation. The purpose of this task is to reduce the uncertainty about the rate and direction of groundwater flow beneath the area and across its boundaries. This specific report deals with the installation of PGS-1 monitoring well which provides information on the lithology and hydrology of the aquifer in the northern area of the Kirtland Air Force Base. The report provides information on the well design; surface geology; stratigraphy; structure; drilling, completion, and development techniques; and borehole geophysics information.

As part of ongoing site characterization studies of Yucca Mountain directed toward this understanding of spatial variability, laboratory measurements of porosity, bull* and particle density, saturated hydraulic conductivity, and sorptivity have been obtained for a set of outcrop samples that form a systematic,two dimensional grid that covers a large exposure of the basal Tiva Canyon Tuff of the Paintbrush Group of Miocene age at Yucca Mountain. The samples form a detailed vertical grid roughly parallel to the transport direction of the parent ash flows, and they exhibit material-property varia- tions in an interval of major lithologic change overlying a potential nuclear-waste repository at Yucca Mountain. The observed changes in hydrologic properties were systematic and consistent with the changes expected for the nonwelded to welded transition at the base of a major ash-flow sequence. Porosity, saturated hydraulic conductivity, and sorptivity decreased upward from the base of the Tiva Canyon Tuff, indicating the progressive compaction of ash- rich volcanic debris and the onset of welding with increased overburden pressure from the accumulating ash-flow sheet. The rate of decrease in the values of these material properties varied with vertical position within the transition interval. In contrast, bulk-density values increased upward, a change that also is consistent with progressive compaction and the onset of welding. Particle-density values remained almost constant throughout the transition interval, probably indicating compositional (chemical) homogeneity. JF - Water-Resources Investigations - U. S.

The demonstration was conducted in partnership with the Army Environmental Center (ABC) Installation Restoration Program (IRP) and ABC's Technology Development Program (TDP). ABC's TDP supported researchers from Tufts University who demonstrated innovative field analytical techniques for the analysis of soil samples for TNT and tetryl. OHM, Inc., was the contractor to ABC's IRP for the JAAP project and was responsible for implementing the adaptive sampling program at selected JAAP sites. The problem of soils contaminated with explosives is extremely important from the Army's perspective. The Army has 28 ordnance manufacturing facilities with soil contamination problems very similar to those found at JAAP. Any enhancement in the characterization and restoration process at these facilities could result in significant time and cost savings.

The TPI aids in the formulation of an accurate conceptual model of flow and transport, an essential first step in the development of a cost effective site characterization strategy. The TPI is demonstrated in the highly complex vadose zone of glacial tills that underlie the Fernald Environmental Remediation Project (FEMP) in Fernald, Ohio. As a result of the TPI, we identify and verify the pertinent flow processes and their controls, such as extensive macropore and fracture flow through layered clays, which must be included in an accurate conceptual model of site-scale contaminant transport. We are able to conclude that the classical modeling and sampling methods employed in some site characterization programs will be insufficient to characterize contaminant concentrations or distributions at contaminated or hazardous waste facilities sited in such media.

Both the PB-EDTA and Ni-EDTA complexes were chosen for study, as they represent respectively metals that are and are not capable of photodeposition onto the TiO (sub 2) catalyst during the photoreaction. Batch reactions were carried out in a jacketed glass pot reactor using 300 ml of 50m g/l metal chelated with an equimolar amount of EDTA and 0.1 wt% of TiO (sub 2) in the solution. The UV source used was a 100 W low-pressure Hg spot lamp. The two systems were studied using Degussa P-25 titanium dioxide, and Aldrich titanium dioxide loaded with Pt and Au. Around 80% removal of the Ni-EDTA complex was attained after 120 min using both catalysts with no photodeposition of Ni onto the catalyst. However, pH precipitation treatment of the reacted solutions indicated that the Ni was still complexed, probably to complexing agents that were EDTA oxidation products. Apparent zero-order kinetics was observed in the P-25 catalyst reaction, whereas apparent first-order kinetics was observed in the metal-loaded TiO (sub 2) catalyst. In contrast the Pb-EDTA complex was completely removed in 10 min using both catalysts. Also, complete Pb deposition onto the catalyst was attained in 30 min for both catalysts. The Pb deposition seemed to first require the degradation of the complex. Total organic carbon was reduced in the Ni-EDTA system 15-21% using both catalysts, and about 33% in the Pb-EDTA system using both catalysts. No reduction of either metal or metal complex was observed when no catalyst was present and the other conditions held constant.

The cleanup prevented possible spontaneous releases of hazardous gases from corroded cylinders that may have affected nearby active test areas at Sandia's Technical Area III. Special waste management, safety, and quality plans were developed and strictly implemented for this project. The project was conceived from a waste management perspective, and waste minimization and management were built into the planning and implementation phases. The site layout was planned to accommodate light and heavy equipment, storage of large quantities of suspect soil, and special areas to stage and treat gases and reactive chemicals removed from the pit, as well as radiation protection areas. Excavation was a tightly controlled activity using experienced gas cylinder and reactive chemical specialists. Hazardous operations were conducted at night under lights, to allow nearby daytime operations to function unhindered. The quality assurance plan provided specific control of, and documentation for, critical decisions, as well as the record of daily operations. Both hand and heavy equipment excavation techniques were utilized. Hand excavation techniques were utilized. Hand excavation techniques allows sealed glass containers to be exhumed unharmed. In the end, several dozen thermal batteries; 5 pounds (2.3 kg) of lithium metal; 6.6 pounds (3.0 kg) of rubidium metal; several kilograms of unknown chemicals; 140 cubic yards (107 cubic meters) of thorium-contaminated soil; 270 cubic yards (205 cubic meters) of chromium-contaminated soil; and 450 gas cylinders, including 97 intact cylinders containing inert, flammable, toxic, corrosive, or oxidizing gases were removed and effectively managed to minimize waste.

This TSPA must try to bound the uncertainties for several issues that will contribute to the decision whether the US should proceed with the development of a nuclear-waste repository at Yucca Mountain. Because site-characterization experiments and data collection will continue for the foreseeable future, the next TSPA (called TSPA-IA) will again only be able to use partially developed models and partial data sets. In contrast to previous analyses however, TSPA-IA must address more specific questions to be of assistance to the investment-analysis deliberations.

A second and much smaller sinkhole was first noticed in early 1995 on an opposite edge of the SPR mine, but with a very similar geological and mine mechanics setting. The cracks become flowpaths for brine incursion, wherein after time it is released into mined openings. Undersaturated ground water gradually enlarges the cracks in salt, leading to further dissolution and eventual collapse of the overlying sand to form sinkholes. Other geologic conditions may have been secondary factors in controlling both mining extent and sinkhole location. An en echelon alignment of sinkholes over other mine edges has been observed. Thus most likely areas of future occurrence at Weeks Island are adjacent to the existing sinkholes; surface inspections are now concentrated at those locations.

This work will be combined with the results of flow modeling in the saturated zone for the purpose of evaluating the suitability of the potential repository under the criteria of 10CFR960. One criterion states, in part, that the groundwater travel time (GWTT) from the repository to the accessible environment must exceed 1,000 years along the fastest path of likely and significant radionuclide travel. Sensitivity analyses have been conducted for one geostatistical realization of one cross-section for the purpose of (1) evaluating the importance of hydrological parameters having some uncertainty and (2) examining conceptual models of flow by altering the numerical implementation of the conceptual model dual permeability (DK) and the equivalent continuum model (ECM). Results of comparisons of the ECM and DK model are also presented in Ho et al.

Future seismic events are predicted using data from the seismic hazard analysis conducted for the Exploratory Studies Facility (ESF). Phenomenological models are developed, including rockfall (thermal-mechanical and seismic) in unbackfilled emplacement drifts, container damage caused by fault displacement within the repository, and flow-path chance caused by changes in strain. Using the composite-porosity flow model (relatively large-scale, regular percolation), seismic events show little effect on total-system releases; using the weeps flow model (episodic pulses of flow in locally saturated fractures), container damage and flow-path changes cause over an order of magnitude increase in releases. In separate calculations using, more realistic representations of faulting, water-table rise caused by seismically induced changes in strain are seen to be higher than previously estimated by others, but not sufficient to reach a potential repository.

Drying a horizontal soil layer creates a barrier to vertical water movement in three ways. First, the drying removes water from the system, intercepting water infiltrating down from the surface. Second, drying a soil layer increases its water storage capacity so the soil will tend to retain rather than transmit water. Third, as a soil layer dries, moisture is removed from progressively smaller interstitial pores so that the hydraulic conductivity of the formation (for liquid flow) decreases. For example, the hydraulic conductivity of a typical sand may decrease by three orders of magnitude as its moisture content is reduced from 20 to 10 percent. This study analyzed the technical and economic feasibility of the subsurface dry barrier concept for containment of a migrating contaminant plume in unsaturated soil. The concept was shown to be a viable option for limiting aqueous migration of pollutants through unsaturated media, with estimated capital costs of between $130,000 and $260,000 for a 1-hectare barrier, and annual operating costs of $10,000 per year.

These systems utilize the high sensitivity of surface acoustic wave (SAW) devices to changes in the mass or other physical properties of a film cast onto the device surface. Using thin polymer films that rapidly (in a few seconds) and reversibly absorb the chemical species of interest, these sensors can be used to detect and monitor a wide range of VOCs. Current minimum detection levels range from about 1 to 10 ppm for typical VOCs in a real-time mode and, by incorporating an adsorbent preconcentrator, periodic (every few minutes) analysis down to the 10-100 ppb range, even in the presence of high concentrations of corrosive vapors, can be achieved. Sensor responses are reproducible, leading to accurate measurements, and the devices can operate over a wide concentration range. Above ground and down-hole systems have been demonstrated at environmental restoration sites for: (1) on-line monitoring of off-gas streams from soil vapor extractions, (2) real-time analysis of gas samples pulled to the surface from a cone penetrometer probe, and (3) in situ monitoring of contaminants in vadose zone monitoring wells.

The UEP model incorporates a gravitational potential to model the displacement of fluids of different densities and can be used for either LNAPLs (lighter than water) or DNAPLs (denser than water). We demonstrate model behavior in a simulated braided stream deposit. Simulations show the influence of textural changes across layers and gravity forces in controlling DNAPL migration. While our results are encouraging, the application of this up-scaled percolation model requires a series of tests both in the laboratory and in the field before judgment of sufficient validity for its intended purpose is achieved.

The capillary-barrier portion of the boxes is 6.0 m long, 2.0 m wide, and 1.2 m high with a slope of 5%. A coarse-grained material was placed in the bottom 25-cm of the box with a 90-cm deep fine-grained material (local soil) on top. A region for laterally diverted water to accumulate and drain was created in the last 1.0 m of the box. The soil at the top is terraced into five, 1.4 m long, level intervals to prevent runoff when adding water. Water is added uniformly to the entire top of the box at a rate of about 66 l/day, or an infiltration rate of 1.7 m/year. The top of the box is covered with fiber-reinforced plastic to minimize evaporation of water, discourage plant growth, and prevent rainfall from contacting the soil. Five drains are spaced along the bottom of the coarse layer. These drains discretize the coarse layer into five collection regions to provide a means of identifying the breakthrough location into the coarse layer. A drain is also located in the downdip collection region of the box. Soil moisture changes were measured in the fine-grained material with a frequency-domain reflectometry (FDR) probe, which was calibrated using soil from the field site at a known moisture content and density.

Kaplan used one-dimensional models to describe the uncertainty and sensitivity of travel times to various processes at Yucca Mountain. Robey and Arnold et al. used a two-dimensional equivalent continuum model (ECM) with inter- and intra-unit heterogeneity in an attempt to assess fast-flow paths through the unsaturated, fractured tuff at Yucca Mountain (GWTT-94). However, significant flow through the fractures in previous models was not simulated due to the characteristics of the ECM, which requires the matrix to be nearly saturated before flow through the fractures is initiated. In the current study (GWTT-95), four two-dimensional cross-sections at Yucca Mountain are simulated using both the ECM and dual-permeability (DK) models. The properties of both the fracture and matrix domains are geostatistically simulated, yielding completely heterogeneous continua. Then, simulations of flow through the four cross-sections are performed using spatially nonuniform infiltration boundary conditions. Steady-state groundwater travel times from the potential repository to the water table are calculated.

The experiments represented limiting conditions of soil venting processes: (1) a through-flow condition in which air flows through the contaminated region, and (2) a bypass-flow condition in which air is channeled around (rather than through) the contaminated region. Predictions using M2NOTS of changing in situ compositions and effluent concentrations for toluene and o-xylene mixtures were compared to the observed results for each condition. Results showed that M2NOTS was able to capture the salient trends and features of multicomponent through-flow and bypass-flow venting processes.

X-ray photoelectron spectroscopy (XPS) and nuclear magnetic resonance (NMR) spectroscopy were used to characterize the chemical and physical nature of Cs-reacted soil minerals. Cd and Cs adsorption isotherms for kaolinite were also measured at variable pH and temperature to establish likely reaction stoichiometries, while atomic force microscopy (AFM) was used to characterize the microtopography of the clay surface. XPS analyses of Cs-exchanged samples show that Cs is sorbed at mineral surfaces and at the interlayer site of smectite clays, although the spectral resolution of XPS analyses is insufficient to differentiate between basal, edge or interlayer sites. (super 133) Cs MAS-NMR results also show that Cs is adsorbed primarily in an interlayer site of montmorillonite and on edge and basal sites for kaolinite. Cd adsorption isotherms on kaolinite were found to be additive using Al (sub 2) O (sub 3) + SiO (sub 2) Cd binding constants. AFM quantification of kaolinite crystallites suggest that edges comprise up to 50% of the BET surface area, and are consistent with NMR and surface charge results that Cs an Cd adsorption occur primarily at edge sites.

The first code models acoustic wave propagation and can be used to generate data sets to calibrate and validate seismic imaging codes. This code reported the fastest timings for acoustic wave propagation codes at a recent SEG (Society of Exploration Geophysicists) meeting. The second code implements a Kirchhoff method for pre-stack depth migration. Development of this code is almost complete, and preliminary results are presented. The third code implements a wave equation approach to seismic migration and is a Paragon implementation of a code from the ARCO Seismic Benchmark Suite.

Its successes and failures are legion and can make or break an operator. A balanced approach must be sought to provide adequate information for safety of operations, neither slighting nor overdoing the effort. The evolving nature of study methods and geologic knowledge essentially mandates that characterization efforts be reviewed periodically. However, indifference, nonchallance, and even outright disdain describe attitudes witnessed in some circles regarding this subject. Unawareness may also be a factor. Unfortunately, several unanticipated events have led to severe economic consequences for the operators. The hard-learned lessons involving several unanticipated geotechnical occurrences at several Gulf Coast salt domes are discussed. The ultimate benefit of valuing site characterization efforts may be more than just enhanced safety and health--costs not expended in lost facilities and litigation can become profit.

The movement of toxins and nutrients in urban areas is largely controlled by interactions with soil and aquifer minerals along hydrologic pathways. Despite progress in theoretical modeling of the effects of these interactions on water chemistry, it is presently impossible to predict overall trends in urban water quality. Determining the controls on stream water chemistry is problematic due to the interplay between different hydrologic reservoirs which cannot be easily observed or measured. Natural tracers, such as dissolved ions and isotopes, provide an indirect method for observing subsurface interactions and are useful for time series analysis of stream water composition. Ionic species are generally nonconservative components because of chemical reactions and are thus useful for discerning the overall discharge chemistry affected by the relationship.

Due to cost and time considerations, data are typically collected on a coarse grid with nodes on 3 to 6 meter (m) centers. Hardware and software are now available which allow the rapid and cost effective collection of information on a much finer sampling grid. In this paper we present and compare total field magnetometry data collected on 3 m centers to total field magnetometry data collected on a grid with centers of 0.5 m or less. We also compare the magnetometry data to time-domain electromagnetic (EM) data collected on a 1 m by 0.2 m grid using the recently introduced Geonics Ltd. EM61 metal detector. All three data sets were collected at an abandoned landfill radioactive Burial Site No. 11 (RB-11) is located on Kirtland Air Force Base near Albuquerque, New Mexico.

To meet this goal, the project identified environmental restoration needs of mixed waste and/or hazardous waste landfill owners (Native American, municipal, DOE, and DoD); documenting potential demonstration sites and the contaminants present at each site; assessing the environmental regulations that would effect demonstration activities; and evaluating site suitability for demonstrating MWLID technologies at the tribal and municipal sites identified. Eighteen landfill sites within a 40.2-km radius of Sandia National Laboratories are listed on the CERCLIS Site/Event Listing for the state of New Mexico. Seventeen are not located within DOE or DoD facilities and are potential offsite MWLID technology demonstration sites. Two of the seventeen CERCLIS sites, one on Native American land and one on municipal land, were evaluated and identified as potential candidates for off-site demonstrations of MWLID-developed technologies. Contaminants potentially present on site include chromium waste, household/commercial hazardous waste, volatile organic compounds, and petroleum products. MWLID characterization technologies applicable to these sites include Magnetometer Towed Array, Cross-borehole Electromagnetic Imaging, SitePlanner (trademark)/PLUME, Hybrid Directional Drilling, Seamist(trademark)/Vadose Zone Monitoring, Stripping Analyses, and X-ray Fluorescence Spectroscopy for Heavy Metals.

However, the analysis of these samples is not only expensive, but can take weeks or months when sent to an off-site laboratory. In contrast, measurement-while-drilling (MWD) screening capability could save money and valuable time by quickly distinguishing between contaminated and uncontaminated areas. Real-time measurements provided by a MVM system would enable on-the-spot decisions to be made regarding sampling strategies, enhance worker safety, and provide the added flexibility of being able to "steer" the drill bit in or out hazardous zones. During measurement-while-drilling, down-hole sensors are located behind the drill bit and linked by a rapid data transmission system to a computer at the surface. As drilling proceeds, data are collected on the nature and extent of the subsurface contamination in real-time. The down-hole sensor is a Geiger-Mueller tube (GMT) gamma radiation detector. In addition to the GMT signal, the MWD system monitors these required down-hole voltages and two temperatures associated with the detector assembly. The Gamma Ray Detection System (GRDS) and electronics package are discussed in as well as the results of the field test. Finally, our conclusions and discussion of future work are presented.

The project, which was funded by the Strategic Environmental Research and Development Program (SERDP), involved the application of a geostatistical-based "smart sampling" methodology and software with on-site field screening of soils for radiation, organic compounds and metals. The software, known as Plume(trademark), was developed at Argonne National Laboratory as part of the DOE/OTD-funded Mixed Waste Landfill Integrated Demonstration (MWLID). The objective of the investigation was to compare an innovative Adaptive Sampling approach that stressed real-time decision-making with a conventional RCRA-driven site characterization carried out by the Air Force. The latter investigation used a standard drilling and sampling plan as mandated by the EPA. To make the comparison realistic, the same contractors and sampling equipment (Geoprobe(reg sign) soil samplers) were used. In both investigations, soil samples were collected at several depths at numerous locations adjacent to burial trenches that contain low-level radioactive waste and animal carcasses. Neither study revealed the presence of contaminants appreciably above risk based action levels, indicating that minimal to no migration has occurred away from the trenches. The combination of Adaptive Sampling with field screening achieved a similar level of confidence compared to the RCRA investigation regarding the potential migration of contaminants at the site. By comparison, the Adaptive Sampling program drilled 28 locations (vs. 36 for the conventional investigation), collected 81 samples (vs. 163), and sent 15 samples (vs. 163) off-site for laboratory analysis. In addition, the field work took 3 1/2 days compared to 13 days for the RCRA investigation.

A critical parameter varied in the simulations is the borehole vacuum which directly affects air flow through the system and indirectly influences soil temperatures and water and NAPL fluid masses. Contaminant migration from the heated zone into the unheated soil can occur if the borehole vacuum, or borehole flow rate, is not sufficient. Under these conditions, evaporation of liquids (water and NAPL) due to the heating can cause flow from the heated zone into the unheated soil. Insufficient air sweep may be indicated by a vapor dominated mass flow rate into the borehole, at least for the present configuration. Sufficient air flow through the heated zone must be provided to contain the contaminants within the heated zone.

The oil is stored in an old salt mine located within a salt dome. In order to assess the hydrologic significance of the sink hole, an In Situ Permeable Flow Sensor was deployed within a sand-filled conduit in the salt dome directly beneath the sinkhole. The flow sensor is a recently developed instrument which uses a thermal perturbation technique to measure the magnitude and direction of the full 3-dimensional groundwater flow velocity vector in saturated, permeable materials. The flow sensor measured substantial groundwater flow directed vertically downward into the salt dome. The data obtained with the flow sensor provided critical evidence which was instrumental in assessing the significance of the sinkhole in terms of the integrity of the oil storage facility.
