Data from core analyses, aquifer testing, and geophysical logging of Denver Basin bedrock aquifers at Castle Pines, Colorado
S. G. Robson, E. R. Banta
1993, Open-File Report 93-442
This report contains data pertaining to the geologic and hydrologic characteristics of the bedrock aquifers of the Denver basin at a site near Castle Pines, Colorado. Data consist of a lithologic- description of about 2,400 ft of drill core and laboratory determinations of mineralogy, grain size, bulk and grain density,...
Physical-property, water-quality, plankton, and bottom-material data for Devils Lake and East Devils Lake, North Dakota, September 1988 through October 1990
Steven K. Sando, Bradley A. Sether
1993, Open-File Report 93-66
Physical-properties were measured and water-quality, plankton, and bottom-material samples were collected at 10 sites in Devils Lake and East Devils Lake during September 1988 through October 1990 to study water-quality variability and water-quality and plankton relations in Devils Lake and East Devils Lake. Physical properties measured include specific conductance, pH,...
Chemical, isotopic, and microbiological evidence for denitrification during transport of domestic wastewater through a thick unsaturated zone in the Mojave Desert, San Bernardino County, California
R. A. Schroeder, P. M. Martin, J.K. Böhlke
1993, Open-File Report 93-414
Nitrogen in downward-infiltrating wastewater discharged from seepage pits (dry wells) at residences in the upper Mojave River Basin, California represents a significant potential source of nitrate contamination to the underlying ground water. However, increases in nitrate concentration in the ground water have not yet been observed. The low nitrate concentration...
Physical, chemical, and biological data for detailed study of irrigation drainage in the Salton Sea area, California, 1988-90
R. A. Schroeder, Mick Rivera
1993, Open-File Report 93-83
This report contains physical, chemical, and biological data associated with irrigation drainage in the Salton Sea area collected during the late 1980's. The data were collected in support of the u.S. Department of the Interior's National Irrigation Water Quality Program in the Western United States to evaluate effects on the...
Estimation of peak-frequency relations, flood hydrographs, and volume-duration-frequency relations of ungaged small urban streams in Ohio
J. M. Sherwood
1993, Open-File Report 93-135
Methods are presented to estimate peak-frequency relations, flood hydrographs, and volume-duration-frequency relations of urban streams in Ohio with drainage areas less than 6.5 square miles. The methods were developed to assist planners in the design of hydraulic structures for which hydrograph routing is required or where the temporary storage of...
Surface- and ground-water quality data at selected landfill sites in Mecklenburg County, North Carolina, 1979-92
D.G. Smith
1993, Open-File Report 93-437
The U.S. Geological Survey initiated an urban water-quality study in 1979 in cooperation with the City of Charlotte and Mecklenburg County, North Carolina. As part of this study, a water-quality monitoring network was established at selected landfill sites in Mecklenburg County. Water-quality samples were collected at 27 surface-water sites and...
Core OL-92 from Owens Lake, southeast California
James L. Bischoff
George I. Smith, editor(s)
1993, Open-File Report 93-683
The drilling project at Owens Lake commenced in April, 1991. This Open-File Report represents an effort to make available to other researchers our preliminary data collected during the first year of study following completion of the core-drilling phase. Nineteen data collections and preliminary interpretations are presented in the following sections....
Hydrogeologic data collected from a crude-oil spill site near Bemidji, Minnesota, 1983-91
S. E. Smith, M. F. Hult
1993, Open-File Report 93-496
The U.S. Geological Survey began a research project at the site of a crude oil spill near Bemidji, Minnesota in 1983. The project is part of the U.S. Geological Survey's Toxic Substances Hydrology Program. The objectives of research at this site are to obtain an understanding of the mobilization, transport,...
Agricultural chemical interchange between ground water and surface water, Cedar River basin, Iowa and Minnesota: A study description
P. J. Squillace, M. J. Liszewski, E.M. Thurman
1993, Open-File Report 92-85
A review of the data collected in the Cedar River basin, Iowa and Minnesota, indicates that atrazine is consistently detected in the main-stem river at concentrations greater than 0.10 microgram per liter even during periods of extended base flow. The primary source of atrazine in the river during these periods...
Water wells on St. Thomas, U.S. Virgin Islands
J.I. Steiger, Richard Kessler
1993, Open-File Report 91-504
This report is a compilation of well-inventory data collected from December 1989 to December 1990 on St. Thomas, U.S. Virgin Islands from 367 wells. The report includes well locations on 1982, 7.5 minute series, USGS topographic maps, which are published to scale, and tables of selected well data. The report...
Selected hydrologic data for southern Utah and Goshen Valleys, Utah, 1890-1992
Bernard J. Stolp, Marilyn J. Drumiler, Lynette E. Brooks
1993, Open-File Report 93-108
This report contains hydrologic data collected in southern Utah and Goshen Valleys from 1890 to 1992. Southern Utah and Goshen Valleys are south of Salt Lake City in Utah County, north-central Utah. The area is bounded on the east and south by the Wasatch Range, on the south by Long...
Streamflow and water-quality data for Lake Purdy and its tributaries, Jefferson and Shelby Counties, Alabama, water years 1987-91
V.E. Stricklin
1993, Open-File Report 93-498
An investigation was begun in North Carolina in 1988 to: (1) quantify nutrient, sediment, and freshwater loadings in canals that collect drainage from cropland field ditches; (2) determine the effects of tide gates and flashboard risers on these loadings and on receiving-water quality; and (3) characterize the effects of drainage...
A coupled surface-water and ground-water flow model for simulation of stream-aquifer interaction
E.D. Swain, E. J. Wexler
1993, Open-File Report 92-138
Ground-water and surface-water flow models traditionally have been developed separately, with interaction between subsurface flow and streamflow either not simulated at all or accounted for by simple formulations. In areas with dynamic and hydraulically well-connected ground-water and surface-water systems, stream-aquifer interaction should be simulated using deterministic responses of both systems...
