Correlation of major eastern earthquake centers with mafic/ultramafic basement masses
Martin Francis Kane
1977, Open-File Report 77-134
Extensive gravity highs and associated magnetic anomalies are present in or near seven major eastern North American earthquake areas as defined by Hadley and Devine (1974). The seven include the five largest of the eastern North American earthquake .centers. The immediate localities of the gravity anomalies are, however, relatively free...

Ground-water resources and geology of Colquitt County, Georgia
E. A. Zimmerman
1977, Open-File Report 77-56
Limestone beds of Eocene, Oligocene, and lower Miocene age, called the principal artesian aquifer, are the chief source of ground water for Colquitt County. Because streams are small, undependable and relatively inaccessible to most users, ground water is the most important source for increased industrial and agricultural water use. Southeast...

1977, Open-File Report 77-433
The concentration of inorganic nitrogen was measured in samples from 521 wells in the upper glacial and Magothy aquifers and from 46 streams in Nassau and Suffolk Counties during May 1971. The predominant form of dissolved nitrogen was nitrate. Nitrate concentrations (as N) in the upper glacial aquifer in both...

1977, Open-File Report 77-251
A mineral survey of the Sheep Mountain Wilderness study area and Cucamonga Wilderness area and additions by the U.S. Geological Survey and Bureau of Mines in 1975 covered about 66,500 acres (26,500 ha) of the San Bernardino and Angeles National Forests in southern California. The two study areas are separated...

Ground-water quality near a sewage-sludge recycling site and a landfill near Denver, Colorado
Stanley G. Robson
1977, Water-Resources Investigations Report 76-132
The Metropolitan Denver Sewage Disposal District and the City and County of Denver operate a sewage-sludge recycling site and a landfill in an area about 15 miles (24 kilometers) east of Denver. The assessment of the effects of these facilities on the ground-water system included determining the direction of ground-water...

Water resources in western Cortland County, New York: hydrologic data for 1972-75 and progress report
Harold L. Shindel, William Buller, William H. Johnston
1977, Open-File Report 77-525
Basic data on the surface water, ground water, and water quality of Cortland County, New York, are presented with a short explanatory text. Seepage investigations showed that during periods of base flow, the surface-water regime cannot be predicted on the basis of flow-duration figures alone. The investigations also indicate that...

Availability of ground water in the lower Connecticut River basin, southwestern New Hampshire
J. E. Cotton
1977, Water-Resources Investigations Report 77-79
This map scale 1:125,000 presents a preliminary assessment of the availability of ground water in the lower Connecticut River basin in southwestern New Hampshire. It is a generalization of several hydrogeologic factors and provides a guideline for ground-water exploration useful in water- and land-use planning. It does not describe the...
A device for automatic photoelectric control of the analytical gap for emission spectrographs
