Water level measurements in 52 shallow boreholes in the San Francisco Bay region
Edward F. Roth
1978, Open-File Report 78-935
Water-level measurements have been read in 52 cased boreholes in the San Francisco bay region. These measurements are compared to water-table depths determined by P-wave velocity. A velocity in excess of 1200 m/s is taken as the depth of the upper surface of the water table. This method works best...
Linear ground-water flow, flood-wave response program for programmable calculators
John Michael Kernodle
1978, Open-File Report 78-356
Two programs are documented which solve a discretized analytical equation derived to determine head changes at a point in a one-dimensional ground-water flow system. The programs, written for programmable calculators, are in widely divergent but commonly encountered languages and serve to illustrate the adaptability of the linear model to use...
Water-quality investigation of the Tyronza River Watershed, Arkansas
T.E. Lamb
1978, Open-File Report 78-175
The results of a 1-year study of surface-water quality in the Tyronza River Watershed are presented to document conditions before implementation of Soil Conservation Service programs. The report includes a general description of the watershed's topography, geology, and aquifers, and the results of monthly measurements of discharge at five sites,...
Potential hazards from future eruptions of Mount St. Helens Volcano, Washington
Dwight Raymond Crandell, Donal Ray Mullineaux
1978, Bulletin 1383-C
Mount St. Helens has been more active and more explosive during the last 4,500 years than any other volcano in the conterminous United States. Eruptions of that period repeatedly formed domes, large volumes of pumice, hot pyroclastic flows, and, during the last 2,500 years, lava flows. Some of this activity...
Susceptibility of coastal plain aquifers to contamination, Fairfax County, Virginia; a computer composite map
Richard H. Johnston, J. Nicholas Van Driel
1978, Open-File Report 78-265
A map is presented that classifies the Coastal Plain of Fairfax County, Virginia according to the susceptibility of the principal sand aquifers to contamination from surface sources. The following classification is used: (1) areas where leachate can readily enter the principal sand aquifers, (2) areas offering great natural protection against...
Principal facts for borehole gravity stations in stratigraphic test well ERDA No. 9, Eddy County, New Mexico
Bruce A. Kososki, Stephen L. Robbins, James W. Schmoker
1978, Open-File Report 78-696
Since 1972 the U.S. Geological Survey has been conducting a series of field evaluation studies in southeastern New Mexico for the Waste Management Division of the Department of Energy (formerly U.S. Energy Research and Development Administration). On the basis of these studies, a tentative site for a nuclear waste repository/disposal...
Subsurface geology and porosity distribution, Madison Limestone and underlying formations, Powder River basin, northeastern Wyoming and southeastern Montana and adjacent areas
James A. Peterson
1978, Open-File Report 78-783
To evaluate the Madison Limestone and associated rocks as potential sources for water supplies in the Powder River Basin and adjacent areas, an understanding of the geologic framework of these units, their lithologic facies patterns, the distribution of porosity zones, and the relation between porosity development and stratigraphic facies is...
Water resources of the Cordova area, Alaska
George A. McCoy, Geoffrey W. Freethey
1978, Open-File Report 78-310
This report is a compilation of ground-water, surface-water, and water-quality data collected by the U.S. Geological Survey, Water Resources Division on Eyak Lake and Power Creek, near Cordova, and wells in and near Cordova, Alaska. Many of these data were collected as part of a cooperative program with the city...
Model analysis of the impact on ground-water conditions of the Muskegon County wastewater disposal system, Michigan
Michael G. McDonald, William B. Fleck
1978, Open-File Report 78-99
A digital model was developed to study the impact on ground-water conditions of the Muskegon County wastewater disposal system. At the disposal site, wastewater is stored in two 850-acre (344-ha) lagoons and then spray-irrigated on crop land. About 70 miles (105 km) of drainage tile, which underlies the irrigated land,...
