Chloroform contamination in part of the alluvial aquifer, Southwest Louisville, Kentucky
R. W. Davis, Edward W. Matthews
1980, Open-File Report 80-219
A well in the Ohio River alluvium at Louisville, Ky., has been yielding water with chloroform concentrations as high as 34.80 milligrams per liter since July 1975. A spill of 5,000 gallons of chloroform in 1970, 120 feet from the well, is probably the source of the contamination. The chloroform...
Analysis of borehole geophysical data in an evaporite sequence at Salt Valley, Utah
Jeffrey J. Daniels, James H. Scott, Robert J. Hite
1980, Open-File Report 80-525
Interpretation of the lithology of an interbed sequence (thin-bedded sediments between thick layers of salt) is often difficult due to the presence of dolomitic sandstones and halite inclusions. The most useful well logging measurements in an evaporite sequence are gamma-ray, neutron-neutron, density, and acoustic velocity. The high resistivity of salt...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Little Laughery Creek, Ripley and Franklin counties, Indiana
Charles G. Crawford, William G. Wilber, James G. Peters
1980, Open-File Report 80-74
The Indiana State Board of Health is developing a State water-quality management plan that includes establishing Limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Little Laughery Creek tributary and Little Laughery Creek was used to predict alternatives for future waste loadings that would...
Potentiometric map of the Winona-Tallahatta aquifer in northwestern Mississippi, fall 1979
B. E. Wasson
1980, Open-File Report 80-598
The potentiometric map of the Winona-Tallahatta aquifer is one of a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources , Bureau of Land and Water Resources, delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop area...
Physical environment and hydrologic characteristics of coal-mining areas in Missouri
J. E. Vaill, James H. Barks
1980, Water-Resources Investigations Report 80-67
Hydrologic information for the north-central and western coal-mining regions of Missouri is needed to define the hydrologic system in these areas of major historic and planned coal development. This report describes the physical setting, climate, coal-mining practices, general hydrologic system, and the current (1980) hydrologie data base in these two...
Quality of urban runoff, Tecolote Creek drainage area, San Diego County, California
James G. Setmire, Wesley L. Bradford
1980, Water-Resources Investigations Report 80-70
The quality of storm runoff from a 9.2-square-mile urbanized watershed, Tecolote Creek, San Diego County, Calif., was studied during nine storms from September 1976 through May 1977. Specific conductance reached 2,100 micromhos and total residue concentrations reached 2,770 milligrams per liter. The chemical oxygen demand concentration in 95% of the...
Geothermal gradients in the Missoula and Bitterroot Valleys, west-central Montana
Robert B. Leonard, Wayne A. Wood
1980, Water-Resources Investigations Report 80-89
Temperature-depth profiles of six cased test holes in the Missoula and Bitterroot Valleys, west-central Montana, consist of linear segments, the intersections of which commonly correspond with lithologic boundaries. Geothermal gradients commonly decreased with depth, probably as a result of compaction and higher quartz content of the deeper sedimentary deposits. There...
Analyses of water, core material, and elutriate samples collected near Sicily Island, Louisiana (Sicily Island area levee project)
Dennis K. Demcheck, Alton J. Dupuy
1980, Open-File Report 80-434
Samples consisting of composited core material were collected from five areas by the U.S. Army Corps of Engineers and analyzed by the U.S. Geological Survey to provide data on the impact of proposed channel excavation and levee construction in the Sicily Island area, Louisiana. Samples of receiving water from the...
Water quality of four lakes in Lakeville, Minnesota
L. H. Tornes, M.R. Have
1980, Water-Resources Investigations Report 80-66
Water-quality characteristics were determined for four selected lakes to provide background data for evaluating changes that may occur in the lakes because of urbanization. Precipitation of calcium carbonate is suggested by high pH values and a decrease in the calcium concentration when magnesium, sodium, and chloride concentrations increase. Pollution is...
