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...
Coal-quality information from the eastern United States
Virgil A. Trent
1980, Miscellaneous Field Studies Map 1190
The United States is attempting to increase domestic coal production in order to reduce dependence upon costly imported petroleum and to stabilize domestic fuel supplies, until alternative sources of energy are developed.  In 1975, coal production for the United States amounted to roughly 654 million short tons (593.5 million metric...
A climatic appraisal of the rehabilitation potential of strippable coal lands in the Green, Yampa, and White River drainage basins, Colorado, Utah, and Wyoming
Terrence J. Toy, Debra S. Grim
1980, Miscellaneous Field Studies Map 1212
The study area of this report is defined as the drainage basins of the Green, Yampa, and White Rivers. The Uinta Mountains of northeastern Utah are excluded because of the lack of sufficient reliable and representative climatological records and because of the unlikelihood of surface-mining within these mountains....
Effects of storm runoff on water quality in the Mill Creek drainage basin, Willingboro, New Jersey
James C. Schornick Jr., David K. Fishel
1980, Water-Resources Investigations Report 80-98
The effect of storm runoff on the quality of water in the the Mill Creek drainage basin in west-central New Jersey is described in this report. The study area (23.7 square kilometers) consists of agricultural and undeveloped land and the residential community of Willingboro. From October 1975 to September 1976,...
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....
Sediment deposition in the White River Reservoir, northwestern Wisconsin
W. G. Batten, S. M. Hindall
1980, Water Supply Paper 2069
The history of deposition in the White River Reservoir was reconstructed from a study of sediment in the reservoir. Suspended-sediment concentrations, particle size, and streamflow characteristics were measured at gaging stations upstream and downstream from the reservoir from November 1975 through September 1977. Characteristics of the sediments were determined from...
Geology and ground water in north-central Santa Cruz County, California
Michael J. Johnson
1980, Water-Resources Investigations Report 80-26
North-central Santa Cruz County is underlain mainly by folded sedimentary rocks of Tertiary and Cretaceous age that have been highly fractured by movements in the San Andreas fault system. Ground water is stored in fractures within shale and mudstone formations and in intergranular pore spaces within fine- to very fine-grained...
Maps showing coal resources of the Jewell Bridge Quadrangle, Buchanan and Tazewell counties, Virginia
Kenneth J. Englund, Nancy K. Teaford
1980, Miscellaneous Field Studies Map 1211
Coal of low-volatile to high-volatile A bituminous rank is the principal developed mineral resource in the Jewell Ridge quadrangle.  The coal beds in the Jewell Ridge quadrangle contain total estimated original resources of 1,519 million tons.  Of this total, 108 million tons have been mined or lost in mining, leaving...
Temperature and solute-transport simulation in streamflow using a Lagrangian reference frame
Harvey E. Jobson
1980, Water-Resources Investigations Report 81-2
A computer program for simulating one-dimensional, unsteady temperature and solute transport in a river has been developed and documented for general use. The solution approach to the convective-diffusion equation uses a moving reference frame (Lagrangian) which greatly simplifies the mathematics of the solution procedure and dramatically reduces errors caused by...
