Distribution and variability of nitrogen and phosphorus in the alluvial, High Plains, Rush Springs, and Blaine aquifers in western Oklahoma
C.J. Becker
1994, Open-File Report 94-41
Aquifers are the primary source of water for drinking and agricultural purposes in western Oklahoma. Health concerns about consuming nitrogen and an increased reliance on ground water for drinking necessitate a better understanding of the cause and effect of contamination from nutrients. The purpose of this project was to compile...
A guide to the design of surface-water-quality studies
R. C. Averett, L.J. Schroder
1994, Open-File Report 93-105
Data interpretation is difficult under the simplest of conditions and requires hydrologic studies that are carefully designed. Good research presupposes carefully collected data, as well as data that were obtained at times when the information content was highest. To accomplish the careful design of hydrologic studies and to...
Regional Aquifer-System Analysis Program of the U.S. Geological Survey, 1978-1992
Ren Jen Sun, Richard H. Johnston
1994, Circular 1099
The major ground-water systems of the United States have been investigated by the U.S. Geological Survey (USGS) through its Regional Aquifer-System Analysis (RASA) Program. During the first 15 years of the program (1978-92), 25 regional aquifer systems, including the most heavily pumped aquifers in the Nation, were intensively studied. As...
Water-resources activities of the U.S. Geological Survey in New Mexico, fiscal year 1992
1994, Open-File Report 93-661
Awareness of our environment in general, and water resources in particular, has brought increased interest in and support of hydrologic data collection and research. The quantity, quality, and distribution of water are extremely important to the future well-being of New Mexico. The State's surface-water resources are minimal and highly variable...

1994, Open-File Report 94-92
Water-resources activities of the U.S. Geological Survey in Nebraska consist principally of hydro- logic data collection and local, areal, or state- wide interpretive studies. These programs are funded by cooperative agreements with State and local agencies, transfer of funds from other Federal agencies, and direct Federal funds. The data and...

1994, Open-File Report 94-339
The U.S. Geological Survey has 82 active or complete-except-report projects of hydrologic investigations ongoing within the New England Program Area. Of this total, 23 are data projects. Data projects contain statistics and data on the conditions of surface water, ground water, water quality and (or) water use for the study...
A summary of water-resources activities of the U.S. Geological Survey in Iowa, fiscal year 1994
R.C. Buchmiller
1994, Open-File Report 94-88
Water-resources programs and activities of the U.S. Geological Survey in Iowa consist principally of hydrologic data collection and investigative studies that address water-resource issues. The work is supported by direct Federal funding, by transfer of funds from other Federal agencies, and by joint-funding agreements with State or local agencies. The Iowa...
Studies of the San Francisco Bay, California, estuarine ecosystem: Pilot regional monitoring program results, 1993
J.M. Caffrey, B.E. Cole, J. E. Cloern, J. Rudek, A.C. Tyler, A.D. Jassby
1994, Open-File Report 94-82
Water samples were collected in the San Francisco Bay estuary during 22 cruises from January through December 1993. Conductivity, temperature, light attenuation, turbidity, oxygen, and in-vivo fluorescence were measured 1ongitudinally and vertically in the main channel of the estuary from south of the Dumbarton Bridge in the southern part of...
Herbicides and nitrate in near-surface aquifers in the midcontinental United States, 1991
Dana W. Kolpin, Michael R. Burkart, E. Michael Thurman
1994, Water Supply Paper 2413
The occurrence and distribution of selected herbicides, atrazine metabolites, and nitrate were determined for near-surface aquifers (within 50 feet of land surface) in the corn- and soybean-producing region of the midcontinental United States. The study region included all or parts of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North...
National Water-Quality Assessment (NAWQA) Program, Long Island-New Jersey (LINJ) Coastal Drainages Study Unit
Paul E. Stackelberg, Mark A. Ayers
1994, Fact Sheet 012-94
In 1991, the U.S. Geological Survey (USGS) began its National Water-Quality Assessment (NAWQA ) program to (1) document the quality of a large, representative part of the Nation's water resources; (2) define water-quality trends; and (3) identify major factors that affect water quality. In addressing these goals, the program will...
Assessment of nonpoint-source contamination of the High Plains Aquifer in south-central Kansas, 1987
John O. Helgesen, Lloyd E. Stullken, A. T. Rutledge
1994, Water Supply Paper 2381-C
Ground-water quality was assessed in a 5,000-square-mile area of the High Plains aquifer in south-central Kansas that is susceptible to nonpoint-source contamination from agricultural and petroleum-production activities. Of particular interest was the presence of agricultural chemicals and petroleum-derived hydrocarbons that might have been associated with brines that formerly were disposed...
Major ions, nutrients, and trace elements in the Mississippi River near Thebes, Illinois, July through September 1993
Howard E. Taylor, Ronald C. Antweiler, Terry I. Brinton, David A. Roth, John A. Moody
1994, Circular 1120-D
Extensive flooding in the upper Mississippi River Basin during summer 1993 had a significant effect on the water quality of the Mississippi River. To evaluate the change in temporal distribution and transport of dissolved constituents in the Mississippi River, six water samples were collected by a discharge-weighted method from July...

1994, Open-File Report 94-91
The U.S. Geological Survey began the Toxic Substances Hydrology Program in 1982 to study, in an interdisciplinary atmosphere, the fate and effects of toxic substances in the environment. The objective of the Program is to provide the earth-science information needed to prevent or mitigate contamination of the Nation's ground and surface waters. To...
Development of saline seeps in Southwestern United States
Kenneth S. Johnson
Anon, editor(s)
1994, Conference Paper, National Conference Publication - Institution of Engineers, Australia
Saline seeps are an increasingly serious problem in semi-arid regions of the southwestern United States. They result when excessive recharge of the shallow ground water in soils raises the water table locally to within one meter of the land surface, and the salinity of the shallow water is increased through...
Lake Michigan's late Quaternary limnological and climate history from ostracode, oxygen isotope, and magnetic susceptibility
Richard M. Forester, Steven M. Colman, Richard L. Reynolds, Loyd D. Keigwin
1994, Journal of Great Lakes Research (20) 93-107
The limnology of Lake Michigan has changed dramatically since the late Pleistocene in response to the expansion and contraction of continental glaciers, to differential isostatic rebound, and to climate change. The lake sediment's stratigraphic trends, magnetic susceptibility, δ18O, and ostracode species abundance ratios provide criteria to identify the lake's response...
