Ground-water levels in Wyoming, 1971 through part of 1980
Jess O. Ragsdale
1982, Open-File Report 82-859
Ground-water levels are measured periodically in a network of about 280 observation wells in Wyoming, mostly in areas where ground water is used in large quantities for irrigation or municipal purposes. The program is conducted by the U.S. Geological Survey in cooperation with the Wyoming State Engineer and the city...
Water resources of the Gig Harbor Peninsula and adjacent areas, Washington
B. W. Drost
1982, Open-File Report 81-1021
The study area is a remnant of a glacial-drift plain nearly surrounded by marine embayments. A water-resources appraisal was made because the area is experiencing rapid population growth. Additional ground water is available for use in the study area. At least 11 cubic feet per second, five times the 1978...
New papers related to remote sensing of the earth
A. P. Colvocoresses, F.J. Doyle
1982, Open-File Report 82-237
Worldwide experience of many individuals and organizations with remote sensing data acquired from space, primarily Landsat-1, -2, and -3, has demonstrated its utility for land use classification, agricultural assessment, energy and resource exploration, and many other applications. There has been some reluctance to adopt these systems in operational programmes because...
Geochemical reconnaissance for uranium occurrences in the Notch Peak intrusive area, House Range, Millard County, Utah
R. A. Cadigan, Keith Robinson
1982, Open-File Report 82-491
Samples collected from the contact metamorphic zone of the Notch Peak intrusive area, House Range, Millard County, Utah, indicate the occurrence of low-grade uranium and thorium ore. Maximum abundances in the altered mineralized rocks in the contact zone are 450 ppm uranium and 480 ppm thorium. Interpretation of factor analysis...
Test and calibration of the Digital World-Wide Standardized Seismograph
Jon Peterson, Charles R. Hutt
1982, Open-File Report 82-1087
During the past decade there has been steady progress in the modernization of the global seismograph network operated by the U.S. Geological Survey (USGS). The World-Wide Standardized Seismograph Network (WWSSN) has been augmented by new stations with advanced instrumentation, including the Seismic Research Observatories (SRO) and the modified High-Gain Long-Period...
Origins and distribution of saline ground waters in the Floridan Aquifer in coastal southwest Florida
W.C. Steinkampf
1982, Water-Resources Investigations Report 82-4052
Twenty-three ground-water samples from the Floridan aquifer in coastal southwest Florida show that water quality deteriorates to the south and west. The waters grade from a fresh calcium magnesium bicarbonate sulfate type to a very saline sodium magnesium chloride type downgradient. Bromide-chloride and specific conductance ratios indicate that dilution of...
Water type and suitability of Oklahoma surface waters for public supply and irrigation, Part 5: Washita river basin through 1979
Jerry D. Stoner
1982, Water-Resources Investigations Report 82-29
Water-quality data through 1979 in the Washita River basin within Oklahoma were examined for water type and suitability for public water supply and for irrigation use. Of 82 stations with available data, 32 stations or 39 percent were considered to have sufficient data for analysis. The classification of water type...
Water quality of Belton Lake, central Texas
H.B. Mendieta, Dale L. Pate
1982, Open-File Report 82-650
The concentrations of dissolved solids, chloride, and sulfate in Belton Lake on the Leon River in central Texas average about 240 milligrams per liter, 40 milligrams per liter, and 30 milligrams per liter, respectively. The water is hard or very hard, averaging 170 milligrams per liter as calcium carbonate. The...
