Ground-water quality and geochemistry, Carson Desert, western Nevada
Michael S. Lico, R. L. Seiler
1994, Open-File Report 94-31
Aquifers in the Carson Desert are the primary source of drinking water, which is highly variable in chemical composition. In the shallow basin-fill aquifers, water chemistyr varies from a dilute calcium bicarbonate-dominated water beneath the irrigated areas to a saline sodium chloride- dominated water beneath unirrigated areas. Water samples from...

Water resources of the Menominee Indian Reservation of Wisconsin
J. T. Krohelski, P.A. Kammerer, Terrence D. Conlon
1994, Water-Resources Investigations Report 93-4053
Water resources of the Menominee Indian Reservation, Wisconsin, were investigated during the period October 1981 through September 1987. The report presents baseline data and some interpretation of ground- and surface-water hydrology and quality of the Reservation. The area stratigraphy consists of basal Precambrian crystalline bedrock and overlying till and sand and...
Agricultural pesticides in six drainage basins used for public water supply in New Jersey, 1990
Tamara Ivahnenko, D.E. Buxton
1994, Water-Resources Investigations Report 93-4101
A reconnaissance study of six drainage basins in New Jersey was conducted to evaluate the presence of pesticides from agricultural runoff in surface water. In the first phase of the study, surface-water public-supply drainage basins throughout New Jersey that could be affected by pesticide applications were identified by use of...
User's guide to revised method-of-characteristics solute-transport model (MOC--version 31)

1994, Water-Resources Investigations Report 94-4115
The U.S. Geological Survey computer model to simulate two-dimensional solute transport and dispersion in ground water (Konikow and Bredehoeft, 1978; Goode and Konikow, 1989) has been modified to improve management of input and output data and to provide progressive run-time information. All opening and closing of files are now done...
Hydrogeology, water quality, and potential for contamination of the Upper Floridan aquifer in the Silver Springs ground-water basin, central Marion County, Florida
G. G. Phelps
1994, Water-Resources Investigations Report 92-4159
The Upper Floridan aquifer, composed of a thick sequence of very porous limestone and dolomite, is the principal source of water supply in the Silver Springs ground-water basin of central Marion County, Florida. The karstic nature of the local geology makes the aquifer susceptible to contaminants from the land surface....
