Data on polychlorinated biphenyls, dieldrin, lead, and cadmium in Wisconsin and Upper Michigan tributaries to Green Bay, July 1987 through April 1988
L. B. House
1990, Open-File Report 89-52
A reconnaissance study was conducted of 22 streams tributary to Green Bay to determine whether any of the streams contribute toxic substances to the bay. This effort was part of a comprehensive investigation of Green Bay funded by the U.S. Environmental Protection Agency, Great Lakes National Program Office. The U.S. Geological...
Geohydrology and water quality of the Roubidoux Aquifer, northeastern Oklahoma
Scott C. Christenson, David L. Parkhurst, Roy W. Fairchild
1990, Open-File Report 90-570
The Roubidoux aquifer is an important source of freshwater for public supplies, commerce, industry, and rural water districts in northeastern Oklahoma. Ground-water withdrawals from the aquifer in 1981 were estimated to be 4.8 million gallons per day, of which about 90 percent was withdrawn in Ottawa County. Wells drilled at...
The Coalinga, California, earthquake of May 2, 1983
Michael J. Rymer, William L. Ellsworth, editor(s)
1990, Professional Paper 1487
At 2342 G.m.t. May 2, 1983, a magnitude (ML) 6.7 earthquake occurred about 12 km northeast of the town of Coalinga, approximately halfway between Los Angeles and San Francisco. The shock was felt from Los Angeles to 200 km north of Sacramento and as far east as Las Vegas. Unlike...
Long-term effects of surface coal mining on ground-water levels and quality in two small watersheds in eastern Ohio
W. L. Cunningham, R.L. Jones
1990, Water-Resources Investigations Report 90-4136
Two small watersheds in eastern Ohio that were surface mined for coal and reclaimed were studied during 1986-89. Water-level and water-quality data were compared with similar data collected during previous investigations conducted during 1976-83 to determine long-term effects of surface mining on the hydrologic system. Before mining, the watersheds were...
Geohydrology and water quality of confined-drift aquifers in the Brooten-Belgrade area, west-central Minnesota
G. N. Delin
1990, Water-Resources Investigations Report 88-4124
Confined-drift aquifers in six aquifer zones identified in a 1,300-square-mile area of west-central Minnesota near Brooten and Belgrade range in thickness from 5 to 110 feet. Transmissivities generally range from 500 to 10,000 feet squared per day, and theoretical well yields generally range from 100 to 900 gallons per minute. Regional...
Reconnaissance geochemical exploration for gold in the Ad Darb area, Kingdom of Saudi Arabia
R.M. Samater, R.P. Christian, P.R. Johnson, A. A. Bookstrom
1990, Open-File Report 90-285
Geochemical data were analyzed for 244 wadi-sediment samples in an attempt to locate gold exploration targets in late Proterozoic metasedimentary and metavolcanic rocks in the Ad Darb area of the southern Arabian Shield. The target was gold mineralization in high-alumina alteration zones of the type that occurs in the Carolina...
Lithology of basin-fill deposits in the Albuquerque-Belen basin, New Mexico
C. A. Kaehler
1990, Water-Resources Investigations Report 89-4162
Sediments that fill the Albuquerque-Belen basin in central New Mexico comprise an aquifer that supplies water to approximately one-third the population of the State. Analysis of driller 's logs and geophysical logs indicate that an area of fine-grained deposits generally underlies the west-central part of the basin. Coarse-grained deposits are...
Earthquake-induced liquefaction features in the coastal setting of South Carolina and in the fluvial setting of the New Madrid seismic zone
S. F. Obermeier, R. B. Jacobson, J. P. Smoot, R.E. Weems, G. S. Gohn, J.E. Monroe, D.S. Powars
1990, Professional Paper 1504
Many types of liquefaction-related features (sand blows, fissures, lateral spreads, dikes, and sills) have been induced by earthquakes in coastal South Carolina and in the New Madrid seismic zone in the Central United States. In addition, abundant features of unknown and nonseismic origin are present. Geologic criteria for interpreting an...
Mineral Resources of the Wabayuma Peak Wilderness Study Area, Mohave County, Arizona
Clay M. Conway, Jerry R. Hassemer, Daniel H. Knepper, James A. Pitkin, Robert C. Jachens, Mark L. Chatman
1990, Bulletin 1737-E
The Wabayuma Peak Wilderness Study Area (AZ-020-037/043), for which a mineral survey was requested by the U.S. Bureau of land Management, encompasses 40,118 acres in northwestern Arizona. Fieldwork was carried out in 1986-88 by the U.S. Bureau of Mines and the U.S. Geological Survey to appraise the identified (known) resources...
Geohydrology and simulation of ground-water flow in the carbonate rocks of the Valley Creek basin, eastern Chester County, Pennsylvania
R. A. Sloto
1990, Water-Resources Investigations Report 89-4169
Sixty-eight percent of the 22.6-square-mile Valley Creek basin is underlain by Cambrian and Ordovician limestone and dolomite. Ground water flows through a network of interconnected secondary openings; primary porosity is virtually nonexistent. Some of these openings have been enlarged by solution. Secondary porosity and permeability exhibit great spatial variability, and...
Road guide to volcanic deposits of Mount St. Helens and vicinity, Washington
Michael P. Doukas
1990, Bulletin 1859
Mount St. Helens, the most recently active and most intensively studied Cascades volcano, is in southwestern Washington. The volcano is a superb outdoor laboratory for studying volcanic processes, deposits of observed events, and deposits whose origins are inferred by classic geologic techniques, including analogy to recent deposits. During the past...
Hydrologic characteristics of the Great Salt Lake, Utah: 1847-1986
Ted Arnow, Doyle W. Stephens
1990, Water Supply Paper 2332
The Great Salt Lake in Utah is a large body of water bordered on the west by barren desert and on the east by a major metropolitan area. It is the fourth largest terminal lake in the world, covering about 2,300 square miles in 1986. Since its historic low elevation...
