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...
Geochemical-exploration studies in the Coeur d'Alene district, Idaho and Montana
Garland Bayard Gott, John B. Cathrall
1980, Professional Paper 1116
The principal ore deposits in the Coeur d'Alene district are lead-zinc-silver replacement veins in Precambrian rocks of the Belt Supergroup. The main ore minerals are galena, tetrahedrite, and sphalerite. The host rocks are mainly quartzite, siltite, and argillite. Cretaceous quartz monzonite locally intrudes the Beltrocks. The geochemical investigations reported here...
Geology of the Round Bay quadrangle, Anne Arundel County, Maryland
James Pierson Minard, Fred E. May, Raymond A. Christopher
1980, Professional Paper 1109
Six Coastal Plain formations and one group crop out in the Round Bay quadrangle near the inner edge of the Atlantic Coastal Plain physiographic province. The quadrangle lies astride the Severn River, in Anne Arundel County, near Annapolis, Md. The seven stratigraphic units aggregate as much as 128 m in...
Water resources data for Louisiana, water year 1980: Volume 2. Southern Louisiana
Water Resources Division, U.S. Geological Survey
1980, Water Data Report LA-80-2
Water resources data for the 1980 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report, in three volumes, contains records for water discharge at...
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...
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...
Cross sections of the Hudson River estuary from Troy to New York City, New York
D.A. Stedfast
1980, Water-Resources Investigations Report 80-24
Data on channel geometry of the Hudson River estuary at 125 cross sections between the Federal Dam at Troy and the norhtern limits of New York City (133 miles) are presented for use in hydraulic modeling, tidal studies, traveltime and water-quality studies, and other uses requiring knowledge of Hudson River...
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...
