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...

L.A. Weiss
1990, Water-Resources Investigations Report 89-4167
Ratios of peak flows in urban basins to peak flows in rural basins in Connecticut are about 1.5 to 6.1 for the 2-year flood and 1.1 to 4.3 for the 100-year flood. The lower ratios, in each case, apply where 30% of the area is served by storm sewers, and...

Flood frequency of the Savannah River at Augusta, Georgia
C.L. Sanders Jr., H.E. Kubik, J.T. Hoke Jr., W.H. Kirby
1990, Water-Resources Investigations Report 90-4024
To fill an increasing need for reliable information on floods of various recurrence intervals on the Savannah River a flood-frequency relation was developed for the long-term gaging station at Augusta, Georgia. The flood-frequency analysis was complicated by the fact that the Savannah River upstream of Augusta has experienced increasing regulation...
Geohydrology and simulated effects of large ground-water withdrawals on the Mississippi River alluvial aquifer in northwestern Mississippi
D. M. Sumner, Billie E. Wasson
1990, Water Supply Paper 2292
The 7,000-square-mile Mississippi River alluvial plain in northwestern Mississippi, locally known as the 'Delta,' is underlain by a prolific aquifer that yielded about 1,100 million gallons per day of water to irrigation wells in 1983. About 20 feet of clay underlying the Delta land surface commonly is underlain by about...
Simulation of ground-water flow in aquifers in Cretaceous rocks in the central Coastal Plain, North Carolina
J. L. Eimers, W.L. Lyke, A. R. Brockman
1990, Water-Resources Investigations Report 89-4153
The principal sources of water-supply in Cretaceous rocks in the central Coastal Plain of North Carolina are the Peedee, Black Creek, and upper Cape Fear aquifers. Ground-water withdrawals from these aquifers have increased from about 0.25 million gallons per day in 1910 to over 29 million gallons per day in...
Geohydrology and water quality of the Roubidoux Aquifer, northeastern Oklahoma
Scott C. Christenson, David L. Parkhurst, Roy W. Fairchild
1990, Open-File Report 90-570
The Roubidoux aquifer is an important source of freshwater for public supplies, commerce, industry, and rural water districts in northeastern Oklahoma. Ground-water withdrawals from the aquifer in 1981 were estimated to be 4.8 million gallons per day, of which about 90 percent was withdrawn in Ottawa County. Wells drilled at...

Techniques for estimation of storm-runoff loads, volumes, and selected constituent concentrations in urban watersheds in the United States
Nancy E. Driver, Gary D. Tasker
1990, Water Supply Paper 2363
Urban planners and managers need information on the quantity of precipitation and the quality and quantity of run off in their cities and towns if they are to adequately plan for the effects of storm runoff from urban areas. As a result of this need, four sets of linear regression...
Evaluation of site-selection criteria, well design, monitoring techniques, and cost analysis for a ground-water supply in Piedmont crystalline rocks, North Carolina
Charles C. Daniel
1990, Water Supply Paper 2341-B
A statistical analysis of data from wells drilled into the crystalline rocks of the Piedmont and Blue Ridge provinces of North Carolina verified and refined previously proposed criteria for the siting of wells to obtain greater than average yields. An opportunity to test the criteria was provided by the expansion...

Evaluation of selenium mobility in soil using sorption experiments and a numerical model, western San Joaquin Valley, California
John L. Fio, Roger Fujii, S. J. Deverel
1990, Open-File Report 90-135
Sorption experiments and a numerical model were used to assess the effects of irrigation and drainage on the depth distribution of selenite and selenate in soils from the western San Joaquin Valley, California. The sorption studies show that selenate (15 to 12,400 micrograms per liter of selenium) is not adsorbed...
Effects of channel modifications on the hydrology of Chicod Creek basin, North Carolina, 1975-87
R.R. Mason Jr., C.E. Simmons, S.A. Watkins
1990, Water-Resources Investigations Report 90-4031
Drainage modifications in this Coastal Plain basin from 1978 to 1981 consisted of channel excavation and clearing of blockages. A study was begun in 1975 to define hydrologic conditions of the basin before, during, and after modifications and to determine what changes were attributed to modifications. Surface-water conditions were altered...

J. E. Quick, Paul S. Bosch
1990, Open-File Report 90-316
Geologic mapping combined with structural, petrographic, and geochemical investigations were used to evaluate the motion and paleogeographic setting of the northern Nabitah fault zone. The orientation and asymmetry of small structures in three areas along the fault zone suggest that motion was primarily left-lateral strike slip. East of the fault...

1990, Open-File Report 88-493
A mass-balance accounting model can be used to guide the management of septic systems and fertilizers to control the degradation of groundwater quality in zones of an aquifer that contributes water to public supply wells. The nitrate nitrogen concentration of the mixture in the well can be predicted for steady-state...

Effects of storm-water runoff on local ground-water quality, Clarksville, Tennessee
Anne B. Hoos
1990, Water-Resources Investigations Report 90-4044
Storm-related water-quality data were collected at a drainage-well site and at a spring site in Clarksville, Tennessee, to define the effects of storm-water runoff on the quality of ground water in the area. A dye-trace test verified the direct hydraulic connection between the drainage well and Mobley Spring. Samples of...

The Cockfield Formation of the Claiborne Group of Tertiary age underlies approximately 4,000 sq mi in western Tennessee. The formation consists primarily of lenticular beds of very fine to coarse sand, silt, clay, and lignite. The Cockfield Formation has been extensively eroded, and the original thickness is preserved only in...
Geochemistry of batch-extract waters derived from spoil material collected at the Cordero coal mine, Powder River basin, Wyoming

1990, Water-Resources Investigations Report 87-4200
Batch-mixing experiments to evaluate postmining water quality at the Cordero Mine were conducted by the U.S. Geological Survey during 1984 to 1985. Contact of groundwater from the spoil aquifer with fresh spoil material caused only small changes in major-element concentrations and in pH, unless sulfide oxidation or contact with soluble...
