1981, Open-File Report 81-143
A 2-year study of the aquatic biota in the Redwood Creek and Mill Creek drainage basins of Redwood National Park indicated that the aquatic productivity is low. Densities of coliform bacteria were low except in Prairie Creek, a tributary to Redwood Creek, where a State park, county fish hatchery, grazing...

1981, Open-File Report 81-1015
Selected hydrogeologic data from the Judith basin, central Montana, have been compiled for use as the physical basis of a ground-water model prepared as part of a 4-year study of Cenozoic and Mesozoic aquifers of the northern Great Plains area of Montana. Records of Cenozoic and Mesozoic aquifers of the...

Fluoride concentrations in water from four principal coastal plain aquifer systems, South Carolina
Phillip W. Johnson, James M. Rhett
1981, Open-File Report 81-140
Ample supplies of ground water are available throughout most of the Coastal Plain of South Carolina, but in many places the fluoride concentrations far exceed (as high as 5.8 mg/L, milligrams per liter) the MCL (maximum concentration limit) established for drinking water by the EPA (U.S. Environmental Protection Agency) and...

1981, Open-File Report 81-326
Selected drill-stem-test data were collected for use in the hydrologic analysis of aquifers in the northern Great Plains area of Montana. To supplement existing data defining the potentiometric surface of various aquifers, shut-in pressures recorded during drill-stem tests of oil and gas test wells were used to calculate the altitude...

The pattern-recognition technique of Bongard and others (1966), Gelfand and others (1976), and Briggs and others (1977) was modified and applied in Southeastern United States to try to detect combinations or interactions of geologic, geophysical, and topographic parameters characteristic of areas with moderate and large earthquakes. The modification involved replacing...
