Quality and movement of ground water in Otter Creek - Dry Creek basin, Cortland County, New York
William Buller, Wallace J. Nichols, J. F. Harsh
1978, Water-Resources Investigations Report 78-3
A steady increase in the chloride and nitrate content of water in a sand and gravel aquifer of glacial origin in the Cortland, N.Y., area prompted a study to obtain data on the extent and source of these constituents. Chloride concentration in the upper part of the aquifer increased generally...
Digital-model simulation of the glacial-outwash aquifer, Otter Creek-Dry Creek basin, Cortland County, New York
O. J. Cosner, J. F. Harsh
1978, Water-Resources Investigations Report 78-71
The city of Cortland, New York, and surrounding areas obtain water from the highly productive glacial-outwash aquifer underlying the Otter Creek-Dry Creek basin. Pumpage from the aquifer in 1976 was approximately 6.3 million gallons per day and is expected to increase as a result of population growth and urbanization. A...
Summary appraisals of the Nation's ground-water resources; Alaska
Chester Zenone, Gary S. Anderson
1978, Professional Paper 813-P
Alaska has enormous surface-water resources, but many of the streams are frozen for most of the year and most contain glacial silt that makes them unacceptable for human use. These factors lend special significance to ground water as a water-supply source, even though perennially frozen ground (permafrost) profoundly modifies ground-water...
Well-response model of the confined area, Bunker Hill ground-water basin, San Bernardino County, California
Timothy J. Durbin, Charles O. Morgan
1978, Water-Resources Investigations Report 77-129
The Bunker Hill ground-water basin, in the vicinity of San Bernardino, Calif., is being artificially recharged with imported water. Current and future artificial recharge of the basin may cause the potentiometric surface in an area of confined ground water to rise above land surface and water to flow from uncapped...
Hydrologic evaluation of part of central Volusia County, Florida
P. W. Bush
1978, Water-Resources Investigations Report 78-89
Municipal wells close to the Atlantic Coast cannot be expected to supply the steadily increasing population of Volusia County, Florida, indefinitely without causing saltwater intrusion problems. Therefore, new wells will be drilled away from the coast. The source of water for the planned artesian aquifer well field will be leakage...
