Hydrology and geochemistry of thermal ground water in southwestern Idaho and north-central Nevada

Description: The study area occupies about 14,500 square miles in southwestern Idaho and north-central Nevada. Thermal ground water occurs under artesian conditions, in discontinuous or compartmented zones, in igneous or sedimentary rocks of Tertiary age. Ground-water movement is generally northward. Temperatures of the ground water range from about 30/sup 0/ to more than 80/sup 0/C. Chemical analyses of water from 12 wells and 9 springs indicate that nonthermal waters are a calcium bicarbonate type; therma… more

Evaluation of heavy-oil and tar sands in Bourbon, Crawford, and Cherokee Counties, Kansas. Final report

Description: The current national energy-resource situation has provided the incentive to investigate more fully deposits of heavy-oil bearing sandstone in southeastern Kansas, as part of a larger, three-state study. The results of this study indicate that the size of the heavy-oil resource in the three Kansas counties studied is smaller than earlier estimates suggested. A resource of 200 to 225 million barrels of oil in-place is estimated to be present in areas of ''known oil occurrence,'' as established b… more

Methodology and concepts for the design of surface storage fills at the Anvil Points Oil Shale Retort Facility

Description: Primary obtectives in design of surface disposal fills for processed and raw oil shales are: (a) to insure long-term physical stability, and (b) to prevent surface runoff, surface erosion, and possible subsurface seepage from degrading the water quality of streams and ground water, it was concluded that the analysis and design of spent shale disposal fills should be based on sound geotechnical engineeering principles, considerable experience, and good judgment. An understanding of the source of… more

Final work plan: supplemental upward vapor intrusion investigation at the former CCC/USDA grain storage facility in Hanover, Kansas.

Description: The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), operated a grain storage facility at the northeastern edge of the city of Hanover, Kansas, from 1950 until the early 1970s. During this time, commercial grain fumigants containing carbon tetrachloride were in common use by the grain storage industry to preserve grain in their facilities. In February 1998, trace to low levels of carbon tetrachloride (below the maximum contaminant level [MCL] of 5.0 {m… more

Characterization of Direct-Push Vadose Zone Sediments from the 241-B and 241-BX Tank Farms

Description: Geochemical tests provide evidence for the transit of a plume of caustic waste solution through the sediment column at the Hanford 241-B and -BX Tank Farms. Direct-push samples recovered from boreholes surrounding Tanks 241-B-110 and 241-BX-102 and related waste transfer lines and diversion boxes included sediments typical of those previously recovered from other localities on the Hanford Site. The Hanford formation sediments are dominantly quartzo-feldspathic sands strewn with lithic fragments… more

Initial investigation of soil mercury geochemistry as an aid to drill site selection in geothermal systems

Description: A mercury-in-soil survey was conducted at the Roosevelt Hot Springs Known Geothermal Resource Area (KGRA), Utah, to evaluate mercury soil geochemistry as a method of selecting exploration well sites in a hot-water geothermal system. Samples of -80 mesh soil were collected at 30.5 m intervals along traverses crossing known structures, surficial geothermal alteration, and exploration well sites, and were analyzed using a Gold Film Mercury Detector. Strong mercury anomalies occur at locations alon… more

Proceedings of the second workshop on hydrologic and geochemical monitoring in the Long Valley Caldera

Description: A workshop was held to review the results of hydrologic and geochemical monitoring and scientific drilling in the Long Valley caldera. Such monitoring is being done to detect changes in the hydrothermal system induced by ongoing magmatic and techonic processes. Data from a 2400-ft deep core hole completed in June 1986 were presented at the 1986 workshop and participants discussed the need and rationale for siting locations for future scientific drilling in the caldera.

Modeling of thermodynamic and chemical changes in low-temperature geothermal systems

Description: A method was developed to incorporate the transport of several chemical components into a model of the transport of fluid mass and heat within a geothermal system. It was demonstrated that the use of coupled hydrological, thermal and chemical data allows for the determination of field porosities, amounts and regions of cool recharge into the system as well as field permeabilities and the hot reservoir volume. With the additional information a reliable prediction of the long-term cooling rate ca… more
