The Quality of Water Discharging From the New River and Clear Fork Basins, Tennessee
R. S. Parker, W. P. Carey
1980, Water-Resources Investigations Report 80-37
The quality of water discharging from a strip-mined basin and a relatively unmined basin on the Cumberland Plateau in Tennessee are examined and compared. The chemical and aesthetic quality of these waters will directly affect the chemical and aesthetic quality of the water flowing through a proposed national river and...
Quantitative analysis versus semiquantitative optical emission spectrographic analysis of chromium, nickel, zinc, vanadium, and molybdenum in organic-rich Paleozoic marine strata, Western United States
George A. Desborough, F. G. Poole, Edwin K. Maughan, H.L. Groves, Gregory N. Green
1980, Open-File Report 80-1271
Comparison of analytical results between the quantitative method and the semiquantitative six-step optical-emission spectrographic method commonly shows significantly lower values for the semiquantitative method. The lower values are most obvious for splits from the same samples of fine-grained organic-rich rocks where the concentrations of the metals chromium, nickel, zinc, vanadium,...
Minisparker profiles from Jeffreys Ledge and adjacent areas in the western Gulf of Maine
Diane M. Eskenasy, Norman G. Bailey
1980, Open-File Report 80-320
A total of 250 kilometers of single-channel seismic-reflection data (28 minisparker profiles) were collected in the coastal waters of Massachusetts, north of and immediately south of Cape Ann, and on the western flank of Jeffreys Ledge, western Gulf of Maine, during the September 1978 cruise of the R/V ASTERIAS. The...
Chemical and physical characteristics of natural ground waters in Michigan: A preliminary report
T. Ray Cummings
1980, Open-File Report 80-953
Wide variations occur in the chemical and physical characteristics of natural groundwaters in Michigan. Dissolved-solids concentrations range from 23 to 2,100 milligrams per liter. Waters having low dissolved-solids concentrations are calcium bicarbonate waters. Sodium, sulfate, and chloride increase as mineralization increases. Iron, aluminum, and titanium are higher at some locations...
Drainage areas of selected surface-water sites in Florida
Donald W. Foose
1980, Open-File Report 80-957
Drainage areas for about 1,500 surface-water sites on streams and lakes in Florida are contained in this report. Sites are described in relation to a nearby city or town, and are located by county, by latitude-longitude, and by topographic map on which it is located. In addition, the surface areas...
