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...
Ground-water withdrawals, water-level changes, land-surface subsidence, and ground-water quality in Fort Bend County, Texas, 1969-87
G.L. Locke
1990, Water-Resources Investigations Report 90-4012
Fort Bend County, which has one of the fastest growing populations of all counties in the United States, is dependent entirely on ground water for public supply. Since 1969, at least 90 large-capacity wells have been drilled, of which 57 were public supply wells, 23 were irrigation wells, and 10...
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...

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...
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...

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...
