U.S. Geological Survey program on toxic waste--ground-water contamination; proceedings of the Third technical meeting, Pensacola, Florida, March 23-27, 1987
Bernard J. Franks, editor(s)
1987, Open-File Report 87-109
Problems of ground-water contamination from leaking surface impoundments are common in surficial aquifers, and are a subject of increasing concern and attention. A potentially widespread contamination problem involves organic chemicals used in wood-preserving processes. Creosote is the most extensively used industrial preservative in the United States today, with more than...
Ground-water-quality assessment of the Delmarva Peninsula, Delaware, Maryland, and Virginia; project description

1987, Open-File Report 87-112
In April 1986, the U.S. Geological Survey began a pilot program to assess the quality of the Nation 's surface water and groundwater resources. This National Water-Quality Assessment (NAWQA) program is designed to acquire and interpret information about a wide range of water quality issues. Three groundwater pilot projects have...
Test plan for 32-bit microcomputers for the Water Resources Division; Chapter A, Test plan for acquisition of prototype 32-bit microcomputers
N.E. Hutchison, A.W. Harbaugh, R.A. Holloway, C.F. Merk
1987, Open-File Report 87-455
The Water Resources Division (WRD) of the U.S. Geological Survey is evaluating 32-bit microcomputers to determine how they can complement, and perhaps later replace, the existing network of minicomputers. The WRD is also designing a National Water Information System (NWIS) that will combine and integrate the existing National Water Data...

Volume 2 of water resources data for the 1985 water year for other Pacific areas consists of records of stage, discharge, and water quality of streams and springs; stage of 2 lakes and a reservoir; and water levels and water quality in wells. This report contains discharge records for 31...
Water Resources Data for Georgia, Water Year 1986
W.R. Stokes, T.W. Hale, G. R. Buell
1987, Water Data Report GA-86-1
This volume of the annual hydrologic data report of Georgia is one of a series of annual reports that document hydrologic data gathered from the U.S. Geological Survey's surface- and ground-water data-collection networks in each State, Puerto Rico, and the Trust Territories. These records of streamflow, ground-water levels, and quality...
Quality of water from freshwater aquifers and principal well fields in the Memphis Area, Tennessee
J. V. Brahana, W. S. Parks, M.W. Gaydos
1987, Water-Resources Investigations Report 87-4052
Water from the freshwater aquifers in the Memphis area is suitable for most uses. Freshwater aquifers are the alluvium and fluvial (terrace) deposits of Quaternary age, the Memphis Sand and Fort Pillow Sand of Tertiary age, and the Ripley Formation and McNairy Sand of Cretaceous age. About 180 million gallons/day...
Water-quality data-collection activities in Colorado and Ohio; Phase II, Evaluation of 1984 field and laboratory quality-assurance practices
Carolyn J. Oblinger Childress, Thomas H. Chaney, Donna Myers, J. Michael Norris, Janet Hren
1987, Open-File Report 87-33
Serious questions have been raised by Congress about the usefulness of water-quality data for addressing issues of regional and national scope and, especially, for characterizing the current quality of the Nation's streams and ground water. In response, the U.S. Geological Survey has undertaken a pilot study in Colorado and Ohio...
Water-quality assessment of Arvada Reservoir, Denver metropolitan area, Colorado
L. J. Britton, N. G. Gaggiani
1987, Water-Resources Investigations Report 87-4107
Water quality data were collected from Arvada Reservoir, Colorado, and from its major inflows, Ralston Creek and Croke Canal, to assess the water quality of the reservoir, to evaluate the effect of water from various sources on the reservoir, and to estimate the trophic state of the reservoir. Data were...
Relations between quality of urban runoff and quality of Lake Ellyn at Glen Ellyn, Illinois
Robert G. Striegl, Ellen A. Cowan
1987, Water Supply Paper 2301
Comparison of flow and chemical data collected at the principal inlet and at the outlets of Lake Ellynman urban lake in the Chicago metropolitan are--shows that detention storage alters the discharge and the quality of urban runoff. Peak water discharge and variation in the concentration of constituents transported by the...
Quantity and quality of urban runoff from the Chester Creek basin Anchorage, Alaska
T. P. Brabets
1987, Water-Resources Investigations Report 86-4312
Urbanization has affected both the flow characteristics and water quality of streams in the Chester Creek basin, of Anchorage, Alaska. Peak flows are higher in the urban rather than rural parts of the basin, and the percent of effective impervious area has a significant effect on storm runoff volumes and...
