Ground water in the Piedmont Upland of central Maryland
Claire A. Richardson
1980, Water-Resources Investigations Report 80-18
Aquifers in a 130-square-mile area of the central Maryland and Piedmont, are shown to be the sole or principal source of water. The study area is underlain chiefly by crystalline rocks and partly by unaltered sandstones and siltstones. The groundwater is derived from local precipitation and generally occurs under water-table...
A comparison of analog and digital modeling techniques for simulating three-dimensional ground-water flow on Long Island, New York
Thomas E. Reilly, Arlen W. Harbaugh
1980, Water-Resources Investigations Report 80-14
A three-dimensional electric-analog model of the Long Island, NY , groundwater system constructed by the U.S. Geological Survey in the early 1970 's was used as the basis for developing a digital, three-dimensional finite-difference model. The digital model was needed to provide faster modifications and more rapid solutions to water-management...

J.F. Santos
1980, Water-Resources Investigations Report 79-21
Generalized maps of average dissolved solids, hardness and nitrate concentrations of water in streams throughout Kentucky were prepared from data collected at more than 100 sites from 1970 to 1975. Average dissolved solids concentrations seldom exceed 250 milligrams per liter. Hardness, mostly of calcium magnesium origin, generally ranges from 60...
Water quality of four lakes in Lakeville, Minnesota
L. H. Tornes, M.R. Have
1980, Water-Resources Investigations Report 80-66
Water-quality characteristics were determined for four selected lakes to provide background data for evaluating changes that may occur in the lakes because of urbanization. Precipitation of calcium carbonate is suggested by high pH values and a decrease in the calcium concentration when magnesium, sodium, and chloride concentrations increase. Pollution is...

Preliminary investigation of a shallow ground-water flow system associated with Connetquot Brook, Long Island, New York
Keith R. Prince
1980, Water-Resources Investigations Report 80-47
Under natural conditions, about 95 percent of the flow in Long Island streams is derived from ground-water seepage. The ground-water system that feeds the streams is a shallow subsystem that overlies the regional subsurface flow system. The Connetquot Brook basin was selected for study because it has not been appreciably...

Robert J. Shedlock
1980, Water-Resources Investigations Report 80-65
A plume of saline water at the base of the glacial outwash aquifer near Vincennes, Indiana, has been drawn into the municipal well field. However, the average chloride concentration of the municipal water, 30 + or - 5 milligrams per liter, did not change significantly from 1976 to 1979. The...
Preliminary analysis of regional-precipitation periodicity
Charles A. Perry
1980, Water-Resources Investigations Report 80-74
Precipitation variability plays a major role in nearly every aspect of the hydrologic cycle. Precipitation is not a random event, but it occurs after a sequence of prerequi-sites has been fulfilled. Recent investigations have shown that activity of the sun can affect atmospheric vorticity, an important factor in precipitation formation....
