Assessment of ground-water contamination in the alluvial aquifer near West Point, Kentucky
M. A. Lyverse, M.D. Unthank
1988, Water-Resources Investigations Report 88-4166
Well inventories, water level measurements, groundwater quality samples, surface geophysical techniques (specifically, electromagnetic techniques), and test drilling were used to investigate the extent and sources of groundwater contamination in the alluvial aquifer near West Point, Kentucky. This aquifer serves as the principal source of drinking water for over 50,000 people....
A modification of the U.S. Geological Survey one-sixth order semiquantitative spectrographic method for the analysis of geologic materials that improves limits of determination of some volatile to moderately volatile elements
D.E. Detra, Elmo F. Cooley
1988, Circular 996
A modification of the one-sixth order semi-quantitative emission spectrographic method for the analysis of 30 elements in geologic materials (Grimes and Marranzino 1968) improves the limits of determination of some volatile to moderately volatile elements. The modification uses a compound-pendulum-mounted filter to regulate the amount of emitted light passing into...
Habitat Suitability Index Models: Diamondback terrapin (nesting) - Atlantic coast
William M. Palmer, Carroll L. Cordes
1988, FWS/OBS 82/10.151
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the diamondback terrapin (Malaclemys terrapin). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
Dye tracing techniques used to determine ground-water flow in a carbonate aquifer system near Elizabethtown, Kentucky
D. S. Mull, J. L. Smoot, T.D. Liebermann
1988, Water-Resources Investigations Report 87-4174
Because of the vulnerability of karst aquifers to contamination and the need for water managers to know recharge areas and groundwater flow characteristics for springs and wells used for public water supply, qualitative and quantitative dye tracing techniques were used during a groundwater investigation in the Elizabethtown area, Hardin County,...
A seismic-stratigraphic investigation of the Madison and associated aquifers; application to ground-water exploration, Powder River basin, Montana-Wyoming
A. H. Balch, editor(s)
1988, Professional Paper 1330
This seismic-stratigraphic investigation is part of a larger 5-year project the "Madison Project" undertaken by the Water Resources Division of the U.S. Geological Survey to study the hydrology of the Madison and associated aquifers. The objectives and methods of investigation of the Madison Project are described by the U.S. Geological...
Potential effects of surface coal mining on the hydrology of the upper Otter Creek-Pasture Creek area, Moorhead coal field, southeastern Montana
N. E. McClymonds, J. A. Moreland
1988, Water-Resources Investigations Report 88-4187
The combined upper Otter Creek-Pasture Creek area, south of Ashland, Montana, contains large reserves of Federal coal for potential lease sale. A hydrologic study was conducted in the area to describe existing hydrologic systems and generalized groundwater quality, to assess potential effects of surface mining on local water resources, and...
Preliminary evaluation of the hydrogeologic system in Owens Valley, California
W.R. Danskin
1988, Water-Resources Investigations Report 88-4003
A preliminary, two-layer, steady-state, groundwater flow model was used to evaluate present data and hydrologic concepts of Owens Valley, California. Simulations of the groundwater system indicate that areas where water levels are most affected by changes in recharge and discharge are near toes of alluvial fans and along the edge...
Relation of trihalomethane-formation potential to water-quality and physical characteristics of small water-supply lakes, eastern Kansas
L. M. Pope, J. A. Arruda, C. H. Fromm
1988, Water-Resources Investigations Report 88-4161
The formation of carcinogenic trihalomethanes during the treatment of public surface water supplies has become a potentially serious problem. The U. S. Geological Survey, in cooperation with the Kansas Department of Health and Environment , investigated the potential for trihalomethane formation in water from 15 small, public water supply lakes...
Analytical results and sample locality map of jasperoid samples from Mackay, Idaho
Sandra J. Soulliere, A.B. Wilson, F. J. Moye, K.P. Rhea
1988, Open-File Report 88-589
This report presents the results of a partial geochemical survey of a part of the Idaho Falls and Dubois 1 x 2 degree quadrangles, Idaho. Samples for geochemical analysis were collected as one of several multidisciplinary studies associated with a U.S. Geological Survey Conterminous United States Mineral Appraisal Program (CUSMAP)...
Geohydrology and digital simulation of the ground-water flow system in the Umatilla Plateau and Horse Heaven Hills area, Oregon and Washington
A. Davies-Smith, E.L. Bolke, C. A. Collins
1988, Water-Resources Investigations Report 87-4268
The Columbia Plateau is underlain by massive basalt flows, with a composite thickness of about 10,000 ft. Structural features within the study area include a series of anticline-syncline pairs. The main avenues of groundwater movement in the basalt are the interflow zone between basalt flows. Individual interflow zones may be...
Statistical summary of the chemical quality of surface water in the Powder River coal basin, the Hanna coal field, and the Green River coal region, Wyoming
D. A. Peterson
1988, Water-Resources Investigations Report 84-4092
A summary of the chemical quality of surface water in the three principal coal-producing areas of Wyoming was intensified by the U.S. Geologic Survey during 1975-81, in response to interest spurred by a dramatic increase in surface mining of the areas. This statistical summary consists of descriptive statistics and regression...
