Relation between urbanization and water quality of streams in the Austin area, Texas
J.E. Veenhuis, R.M. Slade
1990, Water-Resources Investigations Report 90-4107
Selected water-quality properties and constituents of stormflow and base flow were compared to determine the relation between the degree of urbanization and the water quality in a drainage basin. Samples were collected during three flow categories (rising stage and falling stage of stormflow and base flow) at 18 sites on...
Hydrogeology of a hazardous-waste disposal site near Brentwood, Williamson County, Tennessee
Patrick Tucci, D. W. Hanchar, R. W. Lee
1990, Water-Resources Investigations Report 89-4144
Approximately 44,000 gal of industrial solvent wastes were disposed in pits on a farm near Brentwood, Tennessee, in 1978, and contaminants were reported in the soil and shallow groundwater on the site in 1985. In order for the State to evaluate possible remedial-action alternatives, an 18-month study was conducted to...
Water resources data, Florida, water year 1990: Volume 4: Northwest Florida
P.E. Meadows, J.B. Martin, P.R. Mixson
1990, Water Data Report FL-90-4
Water resources data for the 1990 water year in Florida consists of continuous or daily discharge for 349 streams, periodic discharge for 40 streams, miscellaneous discharge for 75 streams, continuous or daily stage for 105 streams, periodic stage for 25 streams, peak discharge for 41 streams, continuous daily tide stage...
Automatic tracer-dilution method used for stage-discharge ratings and streamflow hydrographs on small Iowa streams
P. J. Soenksen
1990, Water-Resources Investigations Report 89-4187
An automatic system was designed to concurrently measure stage and discharge for the purpose of developing stage-discharge ratings and high flow hydrographs on small streams. Stage, or gage height, is recorded by an analog-to-digital recorder and discharge is determined by the constant-rate tracer-dilution method The system measures flow above a...
Geohydrology and simulation of ground-water flow in the carbonate rocks of the Valley Creek basin, eastern Chester County, Pennsylvania
R. A. Sloto
1990, Water-Resources Investigations Report 89-4169
Sixty-eight percent of the 22.6-square-mile Valley Creek basin is underlain by Cambrian and Ordovician limestone and dolomite. Ground water flows through a network of interconnected secondary openings; primary porosity is virtually nonexistent. Some of these openings have been enlarged by solution. Secondary porosity and permeability exhibit great spatial variability, and...
Physical and chemical data for ground water in the Michigan basin, 1986-89
G.T. Dannemiller, Matthew A. Baltusis Jr.
1990, Open-File Report 90-368
Ground-water samples were collected from 459 wells located in the Michigan basin as part of a Regional Aquifer-System Analysis. Data on the physical and chemical characteristics of 476 ground-water samples from these wells represent ground-water characteristics in the Berea Sandstone, Coldwater Shale, Marshall Sandstone, Michigan Formation, Bayport Limestone, Saginaw Formation,...
Cost effectiveness of the stream-gaging program in Nevada
F.E. Arteaga
1990, Water-Resources Investigations Report 87-4213
The stream-gaging network in Nevada was evaluated as part of a nationwide effort by the U.S. Geological Survey to define and document the most cost-effective means of furnishing streamflow information. Specifically, the study dealt with 79 streamflow gages and 2 canal-flow gages that were under the direct operation of Nevada...
Water quality of alluvial aquifers, Carroll and Guthrie counties, Iowa, with emphasis on the occurrence of nitrate and pesticides, 1986-87
M.G. Detroy, M. L. Clark, M.A. Holub, P.K. Hunt
1990, Water-Resources Investigations Report 89-4186
Samples collected from wells in Carroll and Guthrie Counties, Iowa, were analyzed to describe the chemical quality of the ground water in shallow aquifers. The study began in June 1986 with the selection of 20 shallow wells in Carroll County and 22 shallow wells in Guthrie County. These wells were...
Sources and distribution of nitrate in ground water at a farmed field irrigated with sewage treatment-plant effluent, Tallahassee, Florida
M. P. Berndt
1990, Water-Resources Investigations Report 90-4006
The city of Tallahassee, Florida began applying sewage treatment-plant effluent to a sprayfield southeast of the city in 1980. Fertilizers containing inorganic nitrogen were also applied in conjunction with the operation of a commercial farm at this site. Analysis of groundwater in the surficial aquifer and the Upper Floridan aquifer...
Water resources data, Alabama, water year 1989
J. L. Pearman, F.C. Sedberry, V.E. Stricklin, P.W. Cole
1990, Water Data Report AL-89-1
The Water Resources Division of the U.S. Geological Survey, in cooperation with State and Federal agencies, obtains a large amount of data pertaining to the water resources of Alabama each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of...
Flow characteristics of streams that drain the Fort Apache and San Carlos Indian reservations, east-central Arizona, 1930-86
Stanley Baldys, J.A. Bayles
1990, Water-Resources Investigations Report 90-4053
Streamflow characteristics of the Salt River and Gila River basins in the Fort Apache and San Carlos Indian Reservations, were studied in response to pending adjudication of water resources in those basins. Statistical summaries were compiled for 28 streamflow-gaging stations in and near the reservation. Mean annual streamflow for 1930-86...
Reconnaissance investigation of water quality, bottom sediment, and biota associated with irrigation drainage in and near Stillwater Wildlife Management Area, Churchill County, Nevada, 1986-87
R.J. Hoffman, R.J. Hallock, T.G. Rowe, M.S. Lico, H.L. Burge, S.P. Thompson
1990, Water-Resources Investigations Report 89-4105
A reconnaissance was initiated in 1986 to determine whether the quality of irrigation-drainage water in and near the Stillwater Wildlife Management Area, Nevada, has caused or has potential to cause harmful effects on human health, fish, wildlife, or other beneficial uses of water. Samples of surface and groundwater, bottom sediment,...
