Use of an ultra-clean sampling technique with inductively coupled plasma-mass spectrometry to determine trace-element concentrations in water from the Kirkwood-Cohansey Aquifer system, coastal plain, New Jersey
Tamara Ivahnenko, Zoltan Szabo, G.S. Hall
1996, Open-File Report 96-142
Water samples were collected during 1993 from 22 public supply wells screened in the Kirkwood-Cohansey aquifer system; concentrations of 18 trace elements were determined primarily by using inductively coupled plasma-mass spectrometry (ICP-MS) techniques, though graphite furnace atomic adsorption, hydride generation, and cold- vapor flameless atomic adsorption techniques were used for...
Base-flow data for the Little West Fork Basin, Fort Campbell, Tennessee and Kentucky, 1993 and 1994

1996, Open-File Report 96-343
Base-flow data were collected from selected sites within the Little West Fork Red River basin during high and low base-flow conditions in order to support a study of the source and movement of ground water that supplies the Fort Campbell Military Reservation. Stream and spring discharge, water temperature, and specific-conductance...

Low-flow characteristics of streams in Maryland and Delaware
David H. Carpenter, Donald C. Hayes
1996, Water-Resources Investigations Report 94-4020
Hydrologic information on the variability of streamflow during low-flow periods is needed for the effective management of surface-water resources in Maryland and Delaware. Low-flow characteristics derived from streamflow under natural conditions are presented for 94 continuousrecord gaging stations in Maryland, Delaware, and surrounding States, and for 131 low-flow partial-record gaging...

Hydrogeology of structurally extended terrain in the eastern Great Basin of Nevada, Utah, and adjacent states, from geologic and geophysical models
M. D. Dettinger, Donald H. Schaefer
1996, Hydrologic Atlas 694-D
The Great Basin of the western United States encompasses most of Nevada and western Utah (fig. 1). The climate of the region is semiarid to arid, with most precipitation falling as winter Show. The region is characterized by internal drainage (generally no hydrologic outlet to the ocean). Water resources in...
Distribution of oil and natural-gas wells in relation to ground-water flow systems in the Great Basin region of Nevada and Utah, and adjacent states
Donald H. Schaefer
1996, Hydrologic Atlas 694-E
This map publication is one of several in a series concerning various aspects of the ground-water hydrology of the Great Basin in Nevada, Utah, and adjacent States. One report in the series describes the hydrogeologic framework of the Great Basin (Plume and Carlton, 1988). Another shows the ground-water levels for...

Estimation of recharge through selected drainage wells and potential effects from well closure, Orange County, Florida
L. A. Bradner
1996, Open-File Report 96-316
Drainage wells have been used in Orange County, Florida, and surrounding areas to alleviate flooding and to control lake levels since 1904. Over 400 drainage wells have been drilled in the county, but many are now redundant because of surface drainage systems that have been installed within the last two...

Exchangeable hydrogen explains the pH of spodosol Oa horizons
D.S. Ross, R. J. Bartlett, M.B. David, G.B. Lawrence
1996, Soil Science Society of America Journal (60) 1926-1932
The chemistry of extremely acid Oa horizons does not conform to traditional pH, Al, and base saturation relationships. Results from two separate studies of northeastern U.S. forested soils were used to investigate relationships between pH in water or dilute salt solutions and other soil characteristics. In Oa horizons with pH...
Geohydrology and evaluation of stream-aquifer relations in the Apalachicola-Chattahoochee-Flint River basin, southeastern Alabama, northwestern Florida, and southwestern Georgia
Lynn J. Torak, Gary S. Davis, George A. Strain, Jennifer G. Herndon
1996, Water Supply Paper 2460
The lower Apalachicola-Chattahoochee-Flint River Basin is underlain by Coastal Plain sediments of pre-Cretaceous to Quaternary age consisting of alternating units of sand, clay, sandstone, dolomite, and limestone that gradually thicken and dip gently to the southeast. The stream-aquifer system consists of carbonate (limestone and dolomite) and elastic sediments, which define...
Altitude and configuration of the potentiometric surface in the Upper Triassic sedimentary rocks at and near the North Penn Area 12 Superfund site, Worcester Township, Montgomery County, Pennsylvania, July 20-27, 1995

A map showing the altitude of the potentiometric surface defined by measured water levels near the North Penn Area 12 Superfund Site in Worcester Township, Montgomery County, Pa., was constructed from water levels measured in 35 wells from July 20-27, 1995. Observed water-level altitudes range from 435 feet above sea...

1996, Bulletin 2155
Gold mineralization at the Golden Sunlight breccia pipe, southwestern Montana, is related to emplacement of Late Cretaceous alkali-calcic rhyolite and subsequent collapse of the Belt Supergroup wallrock and rhyolite in the pipe. The pipe is inferred to grade downward into an alkalic porphyry molybdenum system. The pipe is cut by...
