Water-Quality Assessment of Southern Florida - Wastewater Discharges and Runoff
Richard L. Marella
1998, Fact Sheet 032-98
Nearly 800 million gallons per day of treated wastewater was discharged in the Southern Florida National Water-Quality Assessment (NAWQA) study unit in 1990, most to the Atlantic Ocean (44 percent) and to deep, saline aquifers (25 percent). About 9 percent was discharged to fresh surface waters and about 22 percent...
Geohydrology of the Winchester Subbasin, Riverside County, California
Charles A. Kaehler, Carmen A. Burton, Terry F. Rees, Allen H. Christensen
1998, Water-Resources Investigations Report 98-4102
The 20-square-mile Winchester structural subbasin is an alluvium-filled paleocanyon that is as much as 900 feet deep. The alluvial aquifer is composed of detrital material that generally ranges in size from clay to fine gravel; the fine and coarse materials are mixed in some places and inter- bedded in others....
Surface-water and suspended-sediment inflow and outflow for Nutria Reservoir No. 3, Zuni Indian Reservation, New Mexico, March 1994 to September 1995
A. C. Gellis
1998, Water-Resources Investigations Report 98-4083
Surface-water and suspended-sediment inflow to and outflow from Nutria Reservoir No. 3 on the Zuni Indian Reservation, western New Mexico, were calculated. The period of study was March 3, 1994, to September 30, 1995. Total runoff into Nutria Reservoir No. 3 during the study period was 6,812 acre-feet....
Extreme precipitation depths for Texas, excluding the Trans-Pecos region
Jennifer Lanning-Rush, William H. Asquith, Raymond M. Slade Jr.
1998, Water-Resources Investigations Report 98-4099
The U.S. Geological Survey, in cooperation with the Texas Department of Transportation, conducted a study of extreme precipitation depths for various durations and storm areas for Texas, excluding the Trans-Pecos region. The extreme precipitation depth is an estimate, from documented storms, of the largest precipitation depth expected to occur over...
Geology, Ground-Water Occurrence, and Estimated Well Yields from the Mariana Limestone, Kagman Area, Saipan, Commonwealth of the Northern Mariana Islands
John P. Hoffmann, Rob Carruth, William Meyer
1998, Water-Resources Investigations Report 98-4077
A study of the geology, ground-water occurrence, and estimated well yields from the Mariana Limestone was done to investigate ground-water availability in the Kagman area, Saipan. The Mariana and Tagpochau Limestone formations form the major aquifer in the Kagman drainage basin. The Mariana Limestone, which is the major water-bearing unit...
Estimate of aquifer properties by numerically simulating ground-water/surface-water interactions, Fort Wainwright, Alaska
Allen S. Nakanishi, Michael R. Lilly
1998, Water-Resources Investigations Report 98-4088
MODFLOW, a finite-difference model of ground-water flow, was used to simulate the flow of water between the aquifer and the Chena River at Fort Wainwright, Alaska. The model was calibrated by comparing simulated ground-water hydrographs to those recorded in wells during periods of fluctuating river levels. The best fit between...
Transmissivity and water quality of water-producing zones in the intermediate aquifer system, Sarasota County, Florida
L. A. Knochenmus, Geronia Bowman
1998, Water-Resources Investigations Report 98-4091
The intermediate aquifer system is an important water source in Sarasota County, Florida, because the quality of water in it is usually better than that in the underlying Upper Floridan aquifer. The intermediate aquifer system consists of a group of up to three water-producing zones separated by less-permeable units that...
Surface-water-quality assessment of the upper Illinois River Basin in Illinois, Indiana, and Wisconsin — Spatial distribution of geochemicals in the fine fraction of streambed sediment, 1987
Faith A. Fitzpatrick, Terri Arnold, John A. Colman
1998, Water-Resources Investigations Report 98-4109
Geochemical data for the upper Illinois River Basin are presented for concentrations of 39 elements in streambed sediment collected by the U.S. Geological Survey in the fall of 1987. These data were collected as part of the pilot phase of the National Water-Quality Assessment Program. A total of 372 sites...
Areas contributing ground water to the Peconic Estuary, and ground-water budgets for the north and south forks and Shelter Island, eastern Suffolk County, New York
C.E. Schubert
1998, Water-Resources Investigations Report 97-4136
The Peconic Estuary, at the eastern end of Long Island, has been plagued by a recurrent algal bloom, locally referred to as ?Brown Tide,? that has caused the severe decline of local marine resources. Although the factors that trigger Brown Tide blooms remain uncertain, groundwater discharge has previously been shown...
Effects of hydrologic, biological, and environmental processes on sources and concentrations of fecal bacteria in the Cuyahoga River, with implications for management of recreational waters in Summit and Cuyahoga Counties, Ohio
Donna N. Myers, G. F. Koltun, Donna S. Francy
1998, Water-Resources Investigations Report 98-4089
Discharges of fecal bacteria (fecal coliform bacteria and Escherichia coli ) to the middle main stem of the Cuyahoga River from storm water, combined sewers, and incompletely disinfected wastewater have resulted in frequent exceedances of bacteriological water-quality standards in a 23-mile reach of the river that flows through the Cuyahoga...
Evaluation of hydrologic data collected at the North Penn Area 12 Superfund Site, Montgomery County, Pennsylvania
Lisa A. Senior, Kevin E. Grazul, Charles R. Wood
1998, Water-Resources Investigations Report 98-4076
The North Penn Area 12 Superfund Site is underlain by the Lockatong Formation, which consists of interbedded gray to black siltstone and shale. The beds of the Lockatong Formation strike northeast and dip about 10d to 20d to the northwest in the vicinity of the site. Ground water moves through...
Steady-state simulation of ground-water flow in the Rush Springs Aquifer, western Oklahoma
M.F. Becker
1998, Water-Resources Investigations Report 98-4082
A simplified steady-state ground-water flow model was prepared for the Rush Springs aquifer in western Oklahoma. A 3-kilometer square grid was established over the area containing two layers with 674 active nodes simulated in the model. The steady-state model simulation used a mean recharge rate of 3.05 x 10-4 feet...
Hydrogeology, water quality, and geochemistry of the Rush Springs aquifer, western Oklahoma
M.F. Becker, D. L. Runkle
1998, Water-Resources Investigations Report 98-4081
The Rush Springs aquifer, in western Oklahoma, is equivalent to the Permian-age Rush Springs Formation. It is composed of very fine-grained to fine-grained sandstone that is massive to highly cross-bedded and is underlain by less-permeable Marlow Formation. Reported irrigation well yields exceed 1,000 gallons per minute; yields reported on 89...
Water resources of the Fort Berthold Indian Reservation, west-central North Dakota
Steven W. Cates, Kathleen M. Macek-Rowland
1998, Water-Resources Investigations Report 98-4098
Water resources of the Fort Berthold Indian Reservation in west-central North Dakota occur as ground water in bedrock and buried-valley aquifers and as surface water in streams and Lake Sakakawea. The bedrock aquifers-the Fox Hills-Hell Creek, Tongue River, and Sentinel Butte store about 93 million acre-feet of water under the...
