Water-quality data-collection activities in Colorado and Ohio; Phase I, Inventory and evaluation of 1984 programs and costs
Janet Hren, Thomas H. Chaney, J. Michael Norris, Carolyn J. Oblinger Childress
1985, Open-File Report 85-574
Pilot projects are being conducted in Colorado and Ohio to determine the extent to which existing water quality data, collected by different groups for various purposes and using different procedures, can be aggregated for use in addressing selected water quality questions of regional and national scope. The project has been...
Ground-water quality data from the northern Mississippi embayment; Arkansas, Missouri, Kentucky, Tennessee, and Mississippi
J. V. Brahana, T. O. Mesko, J.F. Busby, T. F. Kraemer
1985, Open-File Report 85-683
Groundwater quality data were collected from 42 selected wells in the McNairy-Nacatoch-Ripley and the lower Wilcox aquifers of the northern Mississippi embayment. The study is part of the Gulf Coast Regional Aquifer System Analysis (GC RASA) study; the data will be used for geochemical modeling of mineral saturation and mass...
Water resources data, New York, water year 1984, volume 1, eastern New York, excluding Long Island
Gary D. Firda, Richard Lumia, Roger J. Archer, P. M. Burke
1985, Water Data Report NY-84-1
Water resources for the 1984 water year for New York consist of records of stage, discharge, and water quality of streams; stage, discharge, and water quality of lakes and reservoirs; quality of precipitation, and water levels and quality of water in wells. This volume contains records of water discharge at...
Approximate potentiometric surface for the aquifer unit A3, southeastern coastal plain aquifer system of the United States, prior to development
V.A. Stricker
1985, Water-Resources Investigations Report 85-4031
A generalized potentiometric surface map prepared as part of the southeastern United States, Regional Sand Aquifer-System Analysis defines the altitude of water levels under conditions prior to development for aquifer unit A3, the middle group of aquifers in the sand aquifer system. Aquifer unit A3, consisting of Upper Cretaceous and...
Hydrology of Area 52, Rocky Mountain coal province, Wyoming, Colorado, Idaho, and Utah
H. W. Lowham, D. A. Peterson, L. R. Larson, E. A. Zimmerman, B. H. Ringen, K. L. Mora
1985, Open-File Report 83-761
This report is one of a series designed to characterize the hydrology of drainage basins within coal provinces, nationwide. Area 52 (in the Rocky Mountain Coal Province) includes the Green River Basin upstream from the Yampa River, and the Bear River upstream from the Bear Lake - a total of...
Chemical and biological quality of selected lakes in Ohio, 1978 and 1979
C.G. Angelo, John D. Youger
1985, Open-File Report 84-249
Twenty-eight Ohio lakes were sampled by the U.S. Geological Survey and the Ohio Environmental Protection Agency for water-quality characteristics during the spring and summer of 1978 and 1979. This report is the third in a series covering a lake-sampling program that began in 1975. Data include water-column profiles of temperature,...
Estimation of flood peaks from channel characteristics in Ohio
D.K. Roth
1985, Water-Resources Investigations Report 85-4175
Regression equations were developed to estimate flood peaks with selected recurrence intervals of 2 to 100 years for Ohio streams with alluvial and bedrock channels. CHannel-geometry characteristics, rather than basin characteristics, were used as independent variables. Width of active channel was the only channel-geometry characteristic significant at the 5-percent level...
Preparation of polyethylene sacks for collection of precipitation samples for chemical analysis
L.J. Schroder, A.W. Bricker
1985, Water-Resources Investigations Report 85-4067
Polyethylene sacks are used to collect precipitation samples. Washing polyethylene with acetone, hexane, methanol, or nitric acid can change the adsorptive characteristics of the polyethylene. In this study, simulated precipitation at pH 4.5 was in contact with the polyethylene sacks for 21 days; subsamples were removed for chemical analysis at...
Hydrogeologic data from a test well in east-central Duval County, Florida
D.P. Brown, R.A. Johnson, R.A. Broxton
1985, Open-File Report 84-802
A 2,112-foot test well was drilled in east-central Duval County, Florida, to obtain geologic, hydrologic, and water chemistry data. Drill cuttings and water samples were collected, and water-level measurements and lithologic and geophysical logs were made. Deposits to a depth of 575 feet consist of sand, clayey sand, phosphatic sandy...
Federal-State Cooperative Program in Kansas, seminar proceedings, July 1985
T.L. Huntzinger
1985, Open-File Report 85-641
During the past few years, water-resource management in Kansas has undergone reorientation with the creation of the Kansas Water Authority and the Kansas Water office. New thrusts toward long-term goals based on the Kansas State Water plan demand strong communication and coordination between all water-related agencies within the State. The...
Map showing geochemical characteristics of the North Fork Smith River Roadless Areas, Del Norte County, California, Curry and Josephine Counties, Oregon
Norman J. Page, Carl A. Carlson, Floyd Gray, R.A. Carlson, Paul H. Briggs, Joseph Haffty, E.F. Cooley
1985, Miscellaneous Field Studies Map 1423-C
The North Fork Smith River Roadless Areas are located primarily in Del Norte County, northern California, include small parts of Curry and Josephine Counties, Oreg., and cover parts of the Gasquet, Crescent City, and Chetco Peak 15-minute quadrangles. The areas encompass aproximately 39,400 acres of Six rivers National Forest and...
Phytoplankton Abundance and Generic Composition Data for the Potomac River and Estuary, Maryland
R.R.H. Cohen, S.O. Pollock, V.E. Stoelzel, K.E. Boulukos
1985, Open-File Report 84-859
Phytoplankton of the Potomac River and Estuary were counted and identified to the generic level. Double-blind precision tests for an individual counter yielded a standard deviation that was * 10 percent of the mean. Differences between three counters exceeded * 10 percent, and a curve could be fit to calibration...
