M. W. Bradley
1991, Water-Resources Investigations Report 90-4075
An investigation of potential leakage of leachate from the Shelby County landfill near Memphis, West Tennessee, was conducted during 1986-87. The migration of leachate from the landfill to the shallow alluvial aquifer system and the potential leakage to the deeper confined Memphis aquifer of Tertiary age were investigated. A network...

1991, Water-Resources Investigations Report 90-4084
Bydrologic data were collected for the proposed Quitchupah and Pines coal-lease tracts in Sevier and Bnery Counties, Utah, in order to describe the hydrology and potential effects of mining on the hydrologic system. The Quitchupah and Pines coal-lease tracts are near the Southern Utah Fuel Company coal mine in an...
Computer software for converting ground-water and water-quality data from the National Water Information System for use in a geographic information system
J. C. Scott
1991, Water-Resources Investigations Report 90-4200
A geographic information system (GIS) is computer software that provides the capabilities to rapidly display and analyze spatially referenced data. To use a GIS efficiently, software is needed that provides a link between existing spatially referenced data-base systems and the GIS. The U.S. Geological Survey (USGS) stores large amounts of spatially...

Bibliography of Regional Aquifer-System Analysis Program of the US Geological Survey, 1978-91
Ren Jen Sun, John B. Weeks
1991, Water-Resources Investigations Report 91-4122
The Regional Aquifer-System Analysis (RASA) Program of the U.S. Geological Survey was initiated in 1978. The purpose of this program is to define the regional geohydrology and establish a framework of background information on geology, hydrology, and geochemistry of the Nation's important aquifer systems. This information is critically needed to...
Field experiments and simulations of infiltration-rate response to changes in hydrologic conditions for an artificial-recharge test basin near Oakes, southeastern North Dakota
D. M. Sumner, W.M. Schuh, R.L. Cline
1991, Water-Resources Investigations Report 91-4127
Ponded depth in an artificial-recharge basin was used as a management option to conduct turbid water from the James River to the Oakes aquifer. Infiltration-rate response to changes in ponded depth was evaluated for a 15xl5-meter artificial-recharge test basin constructed in a medium-sandy soil in the irrigation area near Oakes,...

The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research efforts are categorized according to whether they are related most directly to: (1) high-level wastes, (2) transuranic wastes, (3) low-level and mixed low-level and hazardous wastes, or (4) uranium mill tailings. Included...
Hydrogeology and ground-water flow in the carbonate rocks of the Little Lehigh Creek basin, Lehigh County, Pennsylvania
R. A. Sloto, L.D. Cecil, L.A. Senior
1991, Water-Resources Investigations Report 90-4076
The Little Lehigh Creek basin is underlain mainly by a complex assemblage of highly-deformed Cambrian and Ordovician carbonate rocks. The Leithsville Formation, Allentown Dolomite, Beekmantown Group, and Jacksonburg Limestone act as a single hydrologic unit. Ground water moves through fractures and other secondary openings and generally is under water-table conditions....
