Hydrogeology and water quality near a solid- and hazardous-waste landfill, Northwood, Ohio
J.T. De Roche, K. J. Breen
1989, Water-Resources Investigations Report 88-4093
Hydrogeology and water quality of ground water and selected streams were evaluated near a landfill in northwestern Ohio. The landfill is used for codisposal of solid and hazardous waste. Water-level and geologic data were collected from 36 wells and 3 surface-water sites during the period November 1983 to November 1985....
Fractures in outcrops in the vicinity of drill hole USW G-4. Yucca Mountain, Nevada; data analysis and compilation
Christopher C. Barton, William R. Page, Terrance L. Morgan
1989, Open-File Report 89-92
Fractures on outcrops in the vicinity of drill hole USW G-4, Yucca Mountain, Nevada, were studied in order to contribute to characterization of fractures for hydrologjc, geomechanical, and tectonic modeling of the Yucca Mountain block and to characterize fractures prior to the excavation of a proposed exploratory shaft located near...
Description of data files compiled for the Central Midwest Regional Aquifer-System Analysis
John O. Helgesen, Cristi V. Hansen
1989, Open-File Report 89-42
Several types of geologic and hydrologic data were collected and compiled as part of the Central Midwest Regional Aquifer-System Analysis. The study described the hydrology of Cambrian-age through Cretaceous-age rocks in all of Kansas and Nebraska and parts of eight other states. Information from both water wells and petroleum wells...
Geology and water resources of Owens Valley, California
Kenneth J. Hollett, W.R. Danskin, W. F. McCaffrey, C.L. Walti
1989, Open-File Report 88-715
Owens Valley, a long, narrow valley located along the east flank of the Sierra Nevada in east-central California, is the main source of water for the city of Los Angeles. The city diverts most of the surface water in the valley into the Owens River-Los Angeles Aqueduct system, which transports...
Geohydrology of the regional aquifer system, western Snake River plain, southwestern Idaho
G. D. Newton
1989, Open-File Report 88-317
A three dimensional groundwater flow model was developed to simulate steady state and nonsteady-state hydrologic conditions of the regional aquifer system in the western Snake River Plain of Idaho. Water budget analysis showed that groundwater recharge was about 1,400,000 acre-ft in 1980; groundwater pumpage was estimated to be 300,000 acre-ft....
Functional requirements of computer systems for the U.S. Geological Survey, Water Resources Division, 1988-97
R.M. Hathaway, J.M. McNellis
1989, Open-File Report 89-274
Investigating the occurrence, quantity, quality, distribution, and movement of the Nation 's water resources is the principal mission of the U.S. Geological Survey 's Water Resources Division. Reports of these investigations are published and available to the public. To accomplish this mission, the Division requires substantial computer technology to process,...
The U.S. Geological Survey Federal-State Cooperative Water- Resources Program: Fiscal Year 1988
Bruce K. Gilbert, William B. Mann IV
1989, Open-File Report 89-389
The Federal-State Cooperative Program is a partnership between the U.S. Geological Survey and State and local agencies. It provides a balanced approach to the study and resolution of water-related problems and to acquiring hydrologic data. The principal program objectives are to: (1) collect, on a systematic basis, data needed for...
Hydrogeologic and chemical data for the O-Field area, Aberdeen Proving Ground, Maryland
P.R. Nemoff, D.A. Vroblesky
1989, Open-File Report 89-238
O-Field, located at the Edgewood area of Aberdeen Proving Ground , Maryland, was periodically used for disposal of munitions, waste chemicals, and chemical-warfare agents from World War II through the 1950' s. This report includes various physical, geologic, chemical, and hydrologic data obtained from well-core, groundwater, surface water, and bottom-sediment...
Annual yield and selected hydrologic data for the Arkansas River Basin Compact, Arkansas-Oklahoma, 1988 water year
Martha A. Moore, T.E. Lamb, Leland D. Hauth
1989, Open-File Report 89-54
The computed annual yield and deficiency of the subbasins as defined in the Arkansas River Compact, Arkansas-Oklahoma, are given in tables. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given in tabular form. Monthly, maximum, minimum, and mean discharge are shown...
Hydrologic environments and water-quality characteristics at four landfills in Mecklenburg County, North Carolina, 1980-86
A.P. Cardinell, C.R. Barnes, W.H. Eddins, R. W. Coble
1989, Water-Resources Investigations Report 89-4035
A water-quality study was conducted during 1980-86 at four landfills in Mecklenburg County, North Carolina. Each landfill has a three-layered hydrogeologic system typical of the Piedmont, consisting of (1) the regolith; (2) a transition zone; and (3) unweathered, fractured crystalline bedrock. As much as 7.6 inches per year of rainfall...
Ground-water hydrology of the central Raton Basin, Colorado and New Mexico
Arthur L. Geldon
1989, Water Supply Paper 2288
The watersheds of the Purgatoire and Apishapa Rivers contain most of the public coal lands in the Raton Basin. The U.S. Geological Survey, in cooperation with the U.S. Bureau of Land Management, investigated the hydrogeology of this area from 1978 to 1982, inventorying 231 wells, 38 springs, and 6 mines,...
Estimating pumping time and ground-water withdrawals using energy- consumption data
R. T. Hurr, D. W. Litke
1989, Water-Resources Investigations Report 89-4107
Evaluation of the hydrology of an aquifer requires knowledge about the volume of groundwater in storage and also about the volume of groundwater withdrawals. Totalizer flow meters may be installed at pumping plants to measure withdrawals; however, it generally is impractical to equip all pumping plants in an area with...

K.J. Ruhl
1989, Water-Resources Investigations Report 89-4067
This report documents the results of a study of the cost-effectiveness of the stream-gaging program in Kentucky. The total surface-water program includes 97 daily-discharge stations , 12 stage-only stations, and 35 crest-stage stations and is operated on a budget of $950,700. One station used for research lacks adequate source of...
Hydrology of the Oakley Fan Area, south-central Idaho
H.W. Young, G. D. Newton
1989, Water-Resources Investigations Report 88-4065
The Oakley Fan area is a broad, crescent-shaped lowland along the southern margin of the Snake River Plain in south-central Idaho. Intensive groundwater development for irrigation has resulted in rapid water-level declines and, as a consequence, designation by the State of four Critical Groundwater Areas. Principal aquifers are in limestone,...
