The hydrogeologic framework and a reconnaissance of ground-water quality in the Piedmont Province of North Carolina, with a design for future study
Douglas Harned
1989, Water-Resources Investigations Report 88-4130
The U.S. Geological Survey is investigating the relation of ground- water quality and land use in the regolith and fractured rock ground-water system of the North Carolina Piedmont. The initial phase of this study provides a description of the ground-water flow system and a review of available ground-water data and...
Geohydrologic data for selected springs in eastern Nevada through 1982, with emphasis on White Pine County
Alex Pupacko, D.B. Wood, R.P. Williams
1989, Open-File Report 88-712
Discharge and water-chemistry data for springs in eastern Nevada , with an emphasis on White Pine County, are compiled and tabulated. Discharge data for springs emanating from the deep carbonate rocks are included. The report contains: (1) miscellaneous discharge measurements for 131 selected springs in White Pine County and vicinity;...
Flow of ground water through fractured carbonate rocks in the Prairie du Chien-Jordan Aquifer, southeastern Minnesota
J. F. Ruhl
1989, Open-File Report 89-253
Contamination of groundwater from point and nonpoint sources (such as landfills, feedlots, agricultural chemicals applied to fields, and septic systems) is a recognized problem in the karst area of southeastern Minnesota. The US Geological Survey, in cooperation with the Minnesota Department of Natural Resources and the Legislative Commission on Minnesota...
Mass-conserving method of characteristics for streamflow modeling
W. G. Sikonia
1989, Open-File Report 89-414
A robust numerical model is presented for the computation of unsteady streamflow on steep river slopes. The one-dimensional model uses the method of characteristics on a specified space-time grid to solve the Saint-Venant equations. An additional continuity equation requirement on each space-time element provides greatly improved conservation of mass over...
Hydrogeologic characteristics of the Valley-Fill aquifer in the Arkansas River valley, Crowley and Otero Counties, Colorado
Gregory A. Nelson, R. T. Hurr, John E. Moore
1989, Open-File Report 89-255
The hydrogeology of the valley-fill aquifer of the Arkansas River valley in Crowley and Otero Counties, Colorado is presented in a series of three maps. The map shows: (1) the altitude and configuration of the bedrock surface beneath the valley-fill material; (2) the altitude and configuration of the water table...
Water Resources Data for California, Water Year 1988. Volume 4. Northern Central Valley Basins and The Great Basin from Honey Lake Basin to Oregon State Line
W.F. Shelton, S.W. Anderson, R.J. Mullen
1989, Water Data Report CA-88-4
Water resources data for the 1988 water year for California consist of records of stage, discharge, and water quality of streams; stage and contents in lakes and reservoirs; and water levels and water quality in wellso Volume 4 contains discharge records for 160 gaging stations; stage and contents for 35...
Water-quality data (October 1987 through September 1988) and statistical summaries (March 1985 through September 1988) for the Clark Fork and selected tributaries from Galen to Missoula, Montana
John H. Lambing
1989, Open-File Report 89-229
Water quality sampling was conducted at eight sites on the Clark Fork and selected tributaries from Galen to Missoula, Mont., from October 1987 through September 1988. This report presents tabulations and statistical summaries of the water quality data. Included in this report are tabulations of streamflow, onsite water quality, and...
Lithology, thickness, and extent of hydrogeologic units underlying the East Portland area, Oregon
S.V. Hartford, W. D. McFarland
1989, Water-Resources Investigations Report 88-4110
The lithology, thickness, and extent of eight distinct hydrogeologic units are described and mapped within the East Portland area of Oregon. The thickness, extent, and top of each unit are shown on contour maps at scales of 1:24,000. Their stratigraphic relations are displayed on a diagrammatic cross section. The geologic...
Geohydrologic aspects for siting and design of low-level radioactive-waste disposal
M. S. Bedinger
1989, Circular 1034
The objective for siting and design of low-level radioactive-waste repository sites is to isolate the waste from the biosphere until the waste no longer poses an unacceptable hazard as a result of radioactive decay. Low-level radioactive waste commonly is isolated at shallow depths with various engineered features to stabilize the...
Hydrogeology and water quality near a solid- and hazardous-waste landfill, Northwood, Ohio
J.T. De Roche, K. J. Breen
1989, Water-Resources Investigations Report 88-4093
Hydrogeology and water quality of ground water and selected streams were evaluated near a landfill in northwestern Ohio. The landfill is used for codisposal of solid and hazardous waste. Water-level and geologic data were collected from 36 wells and 3 surface-water sites during the period November 1983 to November 1985....
