Quality of ground water in Routt County, northwestern Colorado
Kenneth J. Covay, R.L. Tobin
1980, Water-Resources Investigations Report 80-956
Chemical and bacteriological data were collected to describe the quality of water from selected geologic units in Routt County, Colo. Calcium bicarbonate was the dominant water-chemistry type; magnesium, sodium, and sulfate frequently occurred as codominant ions. Specific conductance values ranged from 50 to 6,000 micromhos. Mean values of specific conductance,...

Use of geophysical logs to estimate water-quality trends in carbonate aquifers
Lawrence Mead MacCary
1980, Water-Resources Investigations Report 80-57
The water quality in carbonate aquifers can be determined by analysis of resistivity and porosity logs. When supporting data from water analyses are available, the value of the cementation exponent m can be determined more precisely. Data for this study were taken from logs of oil-test wells, Amstrat sample studies,...

Competition and performance in OCS oil and gas lease sales and lease development, 1954-1969
Walter J. Mead, Philip Edward Sorensen
1980, Open-File Report 80-853
The oil and gas resources of the Outer Continental Shelf represent one of America's largest publicly-owned assets. Through 1978, OCS oil and gas leases had yielded \$40.5 billion in gross production value and produced over \$28.3 billion in direct revenue to the federal government.Policies and procedures for managing the oil...
Ground support data from July 10 to July 29, 1978, for HCMM thermal satellite data of the Powder River Basin, Wyoming
S.H. Miller, Kenneth Watson, Roy Kipfinger
1980, Open-File Report 80-469
Radiometric and meteorological data were acquired at three ground stations located approximately 150 km apart in the Powder River Basin, Wyoming. These data were collected from July. 10 through July 29, 1978, to support the HCMM (Heat Capacity Mapping Mission) thermal satellite data acquired during this same time period. The...
Development of a digital model of ground-water flow in deeply weathered crystalline rock, Chester County, Pennsylvania
Laurence J. McGreevy, Ronald A. Sloto
1980, Water-Resources Investigations Report 80-2
The model developed in this study simulates .recharge to, flow through, and discharge from the water-table aquifer in the upper Pickering Creek basin, a 5.98-square-mile basin representative of most of Chester County, Pennsylvania. The two-dimensional finite-difference model of Trescott, Pinder, and Larson was used with slight modification. The way ground-water...
Final executive summary report; environmental studies, southeastern United States Atlantic Outer Continental Shelf, 1977; geology
Peter Popenoe
1980, Open-File Report 80-147
Starting in mid 1976 and continuing into 1977 a variety of geological studies were carried out by the U. S. Geological Survey on the southeastern U. S. Atlantic Continental Margin to assess conditions and hazards that might cause or distribute oil spills or other pollutants, or constrain petroleum exploration or...
Chemical and physical characteristics of precipitation at selected sites in Florida
G. A. Irwin, R.T. Kirkland
1980, Water-Resources Investigations Report 80-81
Infrequent sampling of precipitation in Florida has been conducted by the U.S. Geological Survey since 1965. A summary of the historical data from 24 sites throughout Florida indicate that the principal ionic composition of atmospheric precipitation samples is calcium-sodium and bicarbonate-chloride with an average specific conductance of 32 micromhos per...
Preliminary delineation of salty ground water in the northern Atlantic Coastal Plain
Harold Meisler
1980, Open-File Report 81-71
Salty ground water underlies freshwater in the eastern part of the northern Atlantic Coastal Plain. The transition zone between freshwater and saltwater is represented in this report by a series of maps showing the depths to chloride concentrations of 250, 1,000, 10,000, and 18,000 milligrams per liter. The maps are...
Biological premonitors of earthquakes: A validation study
Leon Spelly Otis, W.H. Kautz
1980, Open-File Report 80-1152
For the greatest ultimate usefulness to society, the two most important facets of earthquake prediction are (1) a fundamental scientific understanding of the earthquake-triggering process and (2) the identification of reliable and measurable premonitors. A possible approach to both of these problem areas, and one that has received almost no...

1980, Open-File Report 80-72
Oil-shale mining activities in Piceance basin in northwestern Colorado could adversely affect the ground- and surface-water quality in the basin. This study of the hydrology and geochemistry of the area used groundwater solute-transport-modeling techniques to investigate the possible impact of the mines on water quality. Maps of the extent and...
