Evaluation of increases in dissolved solids in ground water, Stovepipe Wells Hotel, Death Valley National Monument, California
Anthony Buono, E.M. Packard
1982, Open-File Report 82-513
Increases in dissolved solids have been monitored in two observation wells near Stovepipe Wells Hotel, Death Valley National Monument, California. One of the hotel 's supply wells delivers water to a reverse-osmosis treatment plant that produces the area 's potable water supply. Should water with increased dissolved solids reach the...
Directory of member organizations of the National Water Data Exchange

1982, Open-File Report 82-902
The National Water Data Exchange (NAWDEX) is a national confederation of water-oriented organizations working together to improve access to water data. It consists of member organizations from all sectors of the water-data community. This Directory provides the names, addresses, and telephone numbers of all NAWDEX member organizations and their designated...
Water quality of the tidal Potomac River and estuary hydrologic data report, 1980 water year
Stephen Blanchard, R.H. Coupe Jr., J.C. Woodward
1982, Open-File Report 82-152
This report contains data on the physical and chemical properties measured in the Tidal Potomac River and Estuary during the 1980 Water Year. Data were collected routinely at five stations, and periodically at 17 stations including three stations near the mouth of the Potomac River in Chesapeake Bay. Each of...
Water-level records for the northern High Plains of Colorado, 1978-82
J.L. Blattner, B.D. Rasmuson
1982, Open-File Report 82-573
Water-level measurements were made in 674 wells during the winter of 1981-82 in the northern High Plains of Colorado. The water-level measurements for the winter of 1981-82 and the four preceding winters are given in a table. This table also contains the location, depth, land-surface elevation, and the aquifer of...

Water Resources Division, U.S. Geological Survey
1982, Circular 875
This U.S. Geological Survey Activities report for fiscal year 1981 presents a summary of the work performed between October 1, 1980 and September 30, 1981. The main sections of this report are: (1) The Year in Review; a brief overview of the significant events of the Geological Survey during fiscal...
Availability and quality of water from the Dakota aquifer, northwest Iowa
M. R. Burkart
1982, Open-File Report 82-264
The Dakota aquifer in northwest Iowa consists of sandstones in the Dakota Formation. It underlies most of the study area and is the most extensive source of ground water in the area. Individual sandstone beds are from less than 10 to more than 150 feet thick. The cumulative thickness of...
Measurement of time of travel and dispersion in streams by dye tracing
E. F. Hubbard, F. A. Kilpatrick, L.A. Martens, J. F. Wilson Jr.
1982, Techniques of Water-Resources Investigations 03-A9
The use of fluorescent dyes and tracing techniques provides a means for measuring the time-of-travel and dispersion characteristics of steady and gradually varied flow in streams. Measurements of the dispersion and concentration of dyes give insight into the behavior of soluble contaminants that may be introduced into a stream. This manual describes methods of measuring time...
Quality assurance practices for the chemical and biological analyses of water and fluvial sediments
Linda C. Friedman, David E. Erdmann
1982, Techniques of Water-Resources Investigations 05-A6
This chapter contains practices used by the U.S. Geological Survey to assure the quality of analytical data for water, fluvial sediment, and aquatic organisms. These practices are directed primarily toward personnel making water quality measurements. Some detail specific quality control techniques, others document quality assurance procedures being used by the...
Water-data program of the U.S. Geological Survey
Bruce K. Gilbert, Thomas J. Buchanan
1982, Circular 863
The U.S. Geological Survey is the principal Federal agency responsible for the collection of hydrologic data needed for the planning, development, use, and management of the Nation 's water resources. These data are the foundation necessary for conducting analytical and interpretive appraisals describing the occurrence and availability of surface and...
Storage and retrieval of ground-water data at the U.S. Geological Survey
Maria W. Mercer, Charles O. Morgan
1982, Circular 856
The U.S. Geological Survey maintains a computerized Ground-Water Site-Inventory (GWSI) file that contains information about wells and springs at sites from all States of the United States. This file contains data collected by U.S. Geological Survey personnel and personnel of cooperating State, local and Federal agencies. The file is easily...
Assessment of the petroleum, coal, and geothermal resources of the Economic Community of West African States (ECOWAS) region
R. E. Mattick (compiler)
1982, Open-File Report 82-714
Approximately 85 percent of the land area of the ECOWAS (Economic Community of West African States) region is covered by basement rocks (igneous and highly metamorphosed rocks) or relatively thin layers of Paleozoic, Upper Precambrian, and 'Continental Intercalaire? sedimentary rocks. These areas have little or no petroleum potential. Areas of...
Depth and temperature of permafrost on the Alaskan Arctic Slope; preliminary results
Arthur H. Lachenbruch, J.H. Sass, L.A. Lawver, M.C. Brewer, T.H. Moses
1982, Open-File Report 82-1039
As permafrost is defined by its temperature, the only way to determine its depth is to monitor the return to equilibrium of temperatures in boreholes that penetrate permafrost. Such measurements are under way in 25 wells on the Alaskan Arctic Slope; 21 are in Naval Petroleum Reserve Alaska (NPRA), and...
An evaluation of water-quality monitoring in the Brandywine Creek basin, Pennsylvania, 1973-78
J.J. Murphy, J.R. Ritter, A.E. Brown, J.P. Chiarella
1982, Open-File Report 81-1115
Data recorded from 1973 through 1978 by monitors on West Branch Brandywine Creek at Modena, East Branch Brandywine Creek below Downingtown, and Brandywine Creek at Chadds Ford were analyzed to evaluate the effectiveness of the monitors in describing water-quality conditions. The data show that the stream at Modena and below...
