Geochemistry of fluoride in the Black Creek aquifer system of Horry and Georgetown Counties, South Carolina — And its physiological implications
Allen L. Zack
1980, Water Supply Paper 2067
High concentrations of fluoride in ground-water supplies in certain areas of Horry and Georgetown Counties, S.C., have been the cause of dental fluorosis (tooth mottling) among persons who have lived in these areas and have ingested the water as children. Geochemical evidence and laboratory experiments demonstrate that fluorapatite in the...
Sulfate reduction in ground water of southeastern Montana
William S. Dockins, G.J. Olson, Gordon A. McFeters, S.C. Turbak, Roger W. Lee
1980, Water-Resources Investigations Report 80-9
Ground water in southeastern Montana was investigated to determine if sulfide production was bacterially mediated. Sulfate—reducing bacteria were detected in 25 of 26 ground—water samples in numbers ranging from 2.0 x 101 to greater than 2.4 x 104 bacteria per 100 milliliters. Stable sulfur isotope fractionation studies indicate a biological...
Additional and revised thermochemical data and computer code for WATEQ2: a computerized chemical model for trace and major element speciation and mineral equilibria of natural waters
James W. Ball, D. Kirk Nordstrom, Everett A. Jenne
1980, Water-Resources Investigations Report 78-116
A computerized chemical model, WATEQ2, has resulted from extensive additions to and revision of the WATEQ model of Truesdell and Jones (Truesdell, A. H., and Jones, B. F., 1974, WATEQ, a computer program for calculating chemical equilibria of natural waters: J. Res. U. S. Geol, Survey, v. 2, p. 233-274)....
Water-quality assessment of the Cypress Creek watershed, Warrick County, Indiana
Linda L. Bobo, Charles A. Peters
1980, Water-Resources Investigations Report 80-35
The U.S. Soil Conservation Service needs chemical, biological, microbiological, and hydrological data to prepare an environmental evaluation of the water quality in the Cypress Creek watershed, Warrick County, Ind., before plans can be devised to (1) improve water quality, (2) minimize flooding, (3) reduce sedimentation, and (4) provide adequate outlets...
Relationships between basic soils-engineering equations and basic ground-water flow equations
Donald G. Jorgensen
1980, Water Supply Paper 2064
The many varied though related terms developed by ground-water hydrologists and by soils engineers are useful to each discipline, but their differences in terminology hinder the use of related information in interdisciplinary studies. Equations for the Terzaghi theory of consolidation and equations for ground-water flow are identical under specific conditions....
A water-quality monitoring network for Vallecitos Valley, Alameda County, California
C. D. Farrar
1980, Water-Resources Investigations Report 80-59
A water-quality monitoring network is proposed to detect the presence of and trace the movement of radioisotopes in the hydrologic system in the vicinity of the Vallecitos Nuclear Center. The source of the radioisotopes is treated industrial wastewater from the Vallecitos Nuclear Center that is discharged into an unnamed tributary...
Paleohydrology of the southern Great Basin, with special reference to water table fluctuations beneath the Nevada Test Site during the late(?) Pleistocene
Isaac Judah Winograd, Gene C. Doty
1980, Open-File Report 80-569
Knowledge of the magnitude of water-table rise during Pleistocene pluvial climates, and of the resultant shortening of groundwater flow path and reduction in unsaturated zone thickness, is mandatory for a technical evaluation of the Nevada Test Site (NTS) or other arid zone sites as repositories for high-level or transuranic radioactive...
Ground-water data for the Riley and Andrews Resource Areas, southeastern Oregon
Paul J. Townley, Constance M. Soja, W.C. Sidle
1980, Open-File Report 80-419
Appraisals of the resources of selected management areas in eastern Oregon are being made by the U.S. Bureau of Land Mangement. To provide needed hydrologic information, the Bureau of Land Management requested the U.S. Geological Survey to inventory ground-water data for the Riley and Andrews Resource Areas. The inventory included...
Water resources data for Georgia, water year 1980
Water Resources Division, U.S. Geological Survey
1980, Water Data Report GA-80-1
Water resources data for the 1980 water year for Georgia consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 105 gaging stations; stage for 9 gaging stations; stage and contents for 17...
Investigation of acidity and other water-quality characteristics of Upper Oyster Creek, Ocean County, New Jersey
Thomas V. Fusillo, J.C. Schornick Jr., H.E. Koester, D.A. Harriman
1980, Water-Resources Investigations Report 80-10
Water-quality data collected in the upper Oyster Creek drainage basin, Ocean County, N.J., indicate that the stream has excellent water quality except for a persistently low pH. The mean concentrations of the major inorganic ions were all less than 6.0 milligrams per liter. Mean concentrations of total nitrogen and total...
Trap-efficiency study, Highland Creek flood retarding reservoir near Kelseyville, California, water years 1966-77
L.F. Trujillo
1980, Open-File Report 80-735
This investigation is part of a nationwide study of trap efficiency of detention reservoirs. In this report, trap efficiency was computed from reservoir inflow and outflow sediment data and from reservoir survey and outflow data. Highland Creek Reservoir is a flood retarding reservoir located in Lake County, near Kelseyville, California....

C. W. Stover, B.G. Reagor, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1228
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
