Planning report for the southwest alluvial basins (east) regional aquifer-system analysis, parts of Colorado, New Mexico, and Texas
D. W. Wilkins, W. B. Scott, C. A. Kaehler
1980, Open-File Report 80-564
The study of the Southwest alluvial basins (east) will involve an analysis of the regional aquifer system in parts of Colorado, New Mexico, and Texas. This area has been divided into 22 basins. The study of the alluvial aquifer-system will be made in the following stages: (1) project planning, (2)...
Preliminary observations of noise spectra at the SRO and ASRO stations
Jon Peterson
1980, Open-File Report 80-992
The seismic noise spectra presented in this report were derived from SRO and ASRO station data for the purpose of evaluating the performance of the seismic instruments. They are also useful for constructing a spectral estimate of earth noise at a quiet site based on noise samples obtained from a...
Ground-water appraisal of the Fishkill-Beacon area, Dutchess County, New York
Deborah S. Snavely
1980, Open-File Report 80-437
The most productive aquifers in the Fishkill-Beacon area, Dutchess County, N.Y., are the sand and gravel beds in the northeast corner of the area and along the valleys of Fishkill and Clove Creeks. The average yield of these aquifers to wells is 190 gal/min (gallons per minute). The most productive...
A preliminary report of the geohydrology of the Mississippi salt-dome basin
C. A. Spiers, L. A. Gandl
1980, Open-File Report 80-595
The U.S. Department of Energy is investigating the suitability of salt domes in the Mississippi salt-dome basin as repositories for storing radioactive wastes. The Department of Energy has requested that the U.S. Geological Survey describe the groundwater hydrology of the Mississippi salt-dome basin, giving special attention to direction and rate...
Potentiometric map of the Winona-Tallahatta aquifer in northwestern Mississippi, fall 1979
B. E. Wasson
1980, Open-File Report 80-598
The potentiometric map of the Winona-Tallahatta aquifer is one of a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources , Bureau of Land and Water Resources, delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop area...
Additional and revised thermochemical data and computer code for WATEQ2: a computerized chemical model for trace and major element speciation and mineral equilibria of natural waters
James W. Ball, D. Kirk Nordstrom, Everett A. Jenne
1980, Water-Resources Investigations Report 78-116
A computerized chemical model, WATEQ2, has resulted from extensive additions to and revision of the WATEQ model of Truesdell and Jones (Truesdell, A. H., and Jones, B. F., 1974, WATEQ, a computer program for calculating chemical equilibria of natural waters: J. Res. U. S. Geol, Survey, v. 2, p. 233-274)....
Test and calibration of the Seismic Research Observatory
Jon Peterson, Charles R. Hutt, L. Gary Holcomb
1980, Open-File Report 80-187
The Seismic Research Observatory (SRO) network is generating an important new data base for seismological research. The SRO systems have extended both the range and resolution of seismic measurements beyond the limits of conventional seismographs and the data are recorded in digital format making it convenient to automate processing and...
The microzonation of the Memphis, Tennessee area
Sunil Sharma, William D. Kovacs
1980, Open-File Report 80-914
Although the probability of a major earthquake in the central U.S. is only one-tenth of the Californian events, any such event is expected to result in damage ten times greater than that anticipated in California. The city of Memphis, which is situated very close to the inferred epicenter of one...
Preliminary report on the mineral resources of the Powderhorn Instant study area, Gunnison and Hinsdale counties, Colorado
William N. Sharp, R.A. Martin, Michael Lane
1980, Open-File Report 80-1057
The Powderhorn Instant Study Area covers approximately 51,000 acres of land under BLM administration located about 80 km (50 mi) southwest of Gunnison, Colorado. A mineral resource survey, made in 1979 by the U.S. Geological Survey and the U.S. Bureau of Mines, indicates that both the mineral potential and the...
Ground-water appraisal in northwestern Big Stone County, west-central Minnesota
W.G. Soukup
1980, Open-File Report 80-568
The development of ground water for irrigation in northwestern Big Stone County has not kept up with development in other irrigable areas of the State. This is due, in part, to the absence of extensive surficial aquifers and the difficulty in locating buried aquifers. Test augering south of Beardsley outlined a...
Analyses of water and dredged material from selected southern Louisiana waterways and selected areas in the Gulf of Mexico, 1976-78
Geraldine R. Stallworth, Helen F. Jordan
1980, Open-File Report 80-694
The U.S. Geological Survey was requested by the U.S. Army Corps of Engineers to provide water-quality data to evaluate the potential environmental effects of (1) dredging activities in selected navigable waterways of southern Louisiana and (2) the disposal of dredged material at selected areas in the Gulf of Mexico. Areas...
Work plan for the Schuylkill River basin, Pennsylvania: Assessment of river quality as related to the distribution and transport of trace metals and organic substances
G.L. Pederson, Thomas H. Yorke, J. K. Stamer
1980, Open-File Report 80-566
The U.S. Geological Survey is making a river-quality assessment of the Schuylkill River basin in Pennsylvania from October 1978 to March 1981. It is part of a continuing program designed to demonstrate the effectiveness of river-quality studies for basin planning and water-resource management. Study objectives include determining (1) presence of...
