Effects of strip mining the abandoned deep Anna S Mine on the hydrology of Babb Creek, Tioga County, Pennsylvania
Daylighting (strip mining of coal seams previously deep mined) operations are being conducted on the Anna S Mine, that underlies about 850 acres that are drained by three major discharges. The Hunter Drift drains an underground area of about 400 acres, the Anna S 1 main entry, an area of 330 acres, and Mitchel 2 discharge an area of about 120 acres. As of August 1, 1979, about 55 acres (15%) had b

Ground-water availability near Fort Wayne, Allen County, Indiana
A 3-year study to determine the groundwater potential of confined glacial aquifers in a large part of Allen County, Ind., was begun in July 1974 by the U.S. Geological Survey. Mapping of outwash sands and gravels delineated two distinct layers of sand and gravel in the southern and eastern parts of the county that merge into one aquifer more than 100 feet thick to the north and west. A digital mod

Plan of study for the Northern Atlantic Coastal Plain Regional Aquifer System Analysis
Sediments of Cretaceous to Holocene age compose the Northern Atlantic Coastal Plain aquifer system in an area of 50,000 square miles in parts of New York, New Jersey, Delaware, Maryland, Virginia, and North Carolina. The aquifer system is a major source of water supply in the area. About 1.4 billion gallons is withdrawn from its aquifers each day. Increasing withdrawal of ground water has created

Development of a digital model of ground-water flow in deeply weathered crystalline rock, Chester County, Pennsylvania
The model developed in this study simulates .recharge to, flow through, and discharge from the water-table aquifer in the upper Pickering Creek basin, a 5.98-square-mile basin representative of most of Chester County, Pennsylvania. The two-dimensional finite-difference model of Trescott, Pinder, and Larson was used with slight modification. The way ground-water evapotranspiration varies with depth

Digital-simulation and projection of head changes in the Potomac-Raritan-Magothy aquifer system, coastal plain, New Jersey
The Potomac-Raritan-Magothy aquifer system of Cretaceous age, which is the principal source of water to the major population and industrial centers in the Coastal Plain of New Jersey, has undergone continuous and widespread reduction in head. The reduced head, already below sea level throughout most of the aquifer system, in conjunction with encroachment of salty water toward centers of pumping, t

Water-quality assessment of the Porter County watershed, Kankakee River basin, Porter County, Indiana
Water type in the 241-square mile Porter County watershed in Indiana, was calcium bicarbonate or mixed calcium bicarbonate and calcium sulfate. Concentrations of dissolved chemical constituents in surface water and contents of chlorinated hydrocarbons in streambed samples in the watershed were generally less than water-quality alert limits set by the U.S. Environmental Protection Agency, except in
