1985, Circular 904-C
This report describes the first phase in evaluating the geology and hydrology of the Basin and Range Province for potential suitability of geohydrologic environments for isolation of high-level radioactive waste. The evaluation of the Province applies the guidelines, discussed in Part I (Bedinger, Sargent, and Reed, 1983) of this report...

1985, Open-File Report 85-87
During the 1983-84 climatic years, the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, collected ground-water level data in Oklahoma from 1,083 sites in 77 counties. This report presents those data points....
Distribution of polychlorinated biphenyls in the Housatonic River and adjacent aquifer, Massachusetts
Frederick B. Gay, Michael H. Frimpter
1985, Water Supply Paper 2266
Polychlorinated biphenyls (PCB's) are sorbed to the fine-grained stream-bottom sediments along the Housatonic River from Pittsfield, Massachusetts, southward to the Massachusetts-Connecticut boundary. The highest PCB concentrations, up to 140,000 micrograms per kilogram, were found in samples of bottom material from a reach of the river between Pittsfield and Woods Pond...
Streamflow and sediment data collected at seven stream-gaging stations in the James River basin downstream from Forestburg, South Dakota, from October 1, 1982 to September 30, 1983
J.R. Little
1985, Open-File Report 85-156
A compilation of streamflow and suspended-sediment data collected from October 1, 1982, to September 30, 1983, at seven gaging stations in the James River basin downstream from Forestburg, South Dakota, is presented in tabular and graphic form. Three of the gaging stations are on the main stem and four are...
Digital models of ground-water flow in the Cape Cod aquifer system, Massachusetts
John H. Guswa, Denis R. LeBlanc
1985, Water Supply Paper 2209
The Cape Cod aquifer system was simulated with three-dimensional finite-difference ground-water-flow models. Five areas were modeled to provide tools that can be used to evaluate the hydrologic impacts of regional water development and waste disposal. The model boundaries were selected to represent the natural hydrologic boundaries of the aquifer. The...
Hydrologic data for urban studies in the Houston, Texas, metropolitan area, 1981
Fred Liscum
1985, Open-File Report 85-163
Hydro! oqic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, and Houston. Studies have been completed in the Dallas-Fort Worth and San Antonio areas. The U.S. Geological Survey, in cooperation with the city of Houston, began studies...
Hydrogeologic data related to the potential for stock-water development on federally owned rangeland near Dillon, Montana
J. F. Levings
1985, Open-File Report 85-170
Existing hydrogeologic data and information were synthesized for 20 sites on federally owned rangeland near Dillon, Montana. The purpose was to assist the U.S. Bureau of Land Management in evaluating the potential for developing additional stock-water supplies. Hydrologic and geologic conditions at most of the sites were verified by onsite...
Effects of low-level dams on the distribution of sediment, trace metals, and organic substances in the lower Schuylkill River basin, Pennsylvania
Thomas H. Yorke, John K. Stamer, Gary L. Pederson
1985, Water Supply Paper 2256-B
Heavy use of the Schuylkill River for municipal water supplies and a history of accidental spills and discharges of trace metals and organic substances have been a concern of State and local officials for many years. The U.S. Geological Survey, as part of their River Quality Assessment Program, developed a...
Water quality of North Carolina streams – Water-quality characteristics for selected sites on the Cape Fear River, North Carolina, 1955-80 – Variability, loads, and trends of selected constituents
J. Kent Crawford
1985, Water Supply Paper 2185-F
Historical water-quality data collected by the U.S. Geological Survey from the Cape Fear River at Lock 1, near Kelly, North Carolina, show increasing concentrations of total-dissolved solids, specific conductance, sulfate, chloride, nitrite plus nitrate nitrogen, magnesium, sodium, and potassium during the past 25 years. Silica and pH show decreasing trends...
Relation between ground-water quality and mineralogy in the coal-producing Norton Formation of Buchanan County, Virginia
John D. Powell, Jerry D. Larson
1985, Water Supply Paper 2274
The geochemical processes controlling ground-water chemistry in the coal-producing strata of southwestern Virginia include hydrolysis of silicates, dissolution of carbonates, oxidation of pyrite, cation exchange, and precipitation of secondary minerals, kaolinite and goethite. Core material from the Norton Formation of the Pennsylvania Period is composed of slightly more than one-half...
Stratigraphy and characteristic mollusks of the Pamunkey Group (Lower Tertiary) and the Old Church Formation of the Chesapeake Group— Virginia coastal plain
Lauck W. Ward
1985, Professional Paper 1346
Along the Pamunkey River and its tributaries can be found a very complete, well-preserved, Tertiary stratigraphic record that reflects the sea-level changes as well as the local tectonic history of the central Virginia Coastal Plain. Using this record, I have described the lower Tertiary units and proposed a sequential model...

Glenn A. Hearne
1985, Water Supply Paper 2205
A three-dimensional digital model of ground-water flow was constructed to represent the dipping anisotropic beds of the Tesuque aquifer system underlying the Pojoaque River basin and vicinity, New Mexico. Simulations of steady-state conditions and historical ground-water withdrawals were consistent with observed data. The model was used to simulate the response...
Study and interpretation of the chemical characteristics of natural water
John David Hem
1985, Water Supply Paper 2254
The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from human activities. Broad interrelationships among these processes and...
