Hydrology of area 15, Eastern Coal province, Kentucky and Tennessee
David W. Leist, Ferdinand Quinones, D. S. Mull, Mary Young
1982, Open-File Report 81-809
Area 15, in Eastern Kentucky and Tennessee consists of 3,095 square miles in the Cumberland, Rockcastle and Laurel River basins. The area is underlain by Permian, Pennsylvanian, Mississippian rocks. The Breathitt Formation of Pennsylvanian age crops out in about 75% of the area and contains most of the coal. About...
Effects of urban development on the aquifers in the Memphis area, Tennessee
D. D. Graham
1982, Water-Resources Investigations Report 82-4024
Ground-water withdrawals from aquifers in the Memphis area average about 190 Mgal/d. Potential problems associated with increases in pumpage and urban development are lowered water levels, contamination of the aquifers, and land subsidence. Long-term water-level declines in the Memphis Sand, the principal artesian aquifer of the area, range from less...
Nitrate-nitrogen concentrations in ground water from three selected areas in Kansas
Timothy B. Spruill
1982, Water-Resources Investigations Report 82-11
Nitrate-nitrogen data collected during 1976-79 from 333 wells in western, central, and eastern Kansas were summarized and statistically analyzed on the basis of area, aquifer, and well depth. Concentrations exceeding 10 milligrams per liter occurred generally in wells less than 100 feet in depth, indicating that nitrate-nitrogen concentrations in ground...
Water-quality characteristics of Everglades National Park, 1959-77, with reference to the effects of water management
Bradley G. Waller
1982, Water-Resources Investigations Report 82-34
The U.S. Geological Survey has collected water-quality data in the Everglades National Park since 1959. Major ions, macronutrients, trace elements, and pesticides are the primary chemical groups analyzed. The period of record and frequency of sampling vary for each chemical group, with the longest record for the major ions and...
Quality of surface water at selected sites in the Suwannee River basin, Florida
J.E. Coffin
1982, Open-File Report 82-103
This report presents the results of analyses of water-quality samples collected from 14 surface-water sites in the Suwannee River basin in Florida from January through December 1980. The analyses of samples collected routinely included: nutrients, total organic carbon, and 5-day biochemical oxygen demand, bimonthly; and trace metals, annually. The array...
Availability and quality of water from the Dakota aquifer, northwest Iowa
M. R. Burkart
1982, Open-File Report 82-264
The Dakota aquifer in northwest Iowa consists of sandstones in the Dakota Formation. It underlies most of the study area and is the most extensive source of ground water in the area. Individual sandstone beds are from less than 10 to more than 150 feet thick. The cumulative thickness of...
Eruptive history, petrology, and petrogenesis of the Joe Lott Tuff Member of the Mount Belknap Volcanics, Marysvale volcanic field, west-central Utah
Karin E. Budding
1982, Open-File Report 82-891
The Joe Lott Tuff Member of the Mount Belknap Volcanics is the largest rhyolitic ash-flow tuff sheet in the Marysvale volcanic field. It was erupted 19 m.y. ago, shortly after the changeover from intermediate-composition calc-alkalic volcanism to bimodal basalt-rhyolite volcanism. Eruption of the tuff resulted in the formation of the...
