Aquifer-test evaluation and potential effects of increased ground-water pumpage at the Stovepipe Wells Hotel area, Death Valley National Monument, California
L. R. Woolfenden, Peter Martin, Brian Baharie
1988, Water-Resources Investigations Report 87-4270
Ground-water use in the Stovepipe Wells Hotel area in Death Valley National Monument is expected to increase significantly if the nonpotable, as well as potable, water supply is treated by reverse osmosis. During the peak tourist season, October through March, ground-water pumpage could increase by 37,500 gallons per day, or...
Ground-water conditions in the Anza-Terwilliger area, with emphasis on the Cahuilla Indian Reservation, Riverside County, California, 1973-86
L. R. Woolfenden, D.J. Bright
1988, Water-Resources Investigations Report 88-4029
Demand for groundwater in the 96-sq mi Anza Terwilliger area of California has increased in recent years because of population growth and agricultural development. In order to evaluate the potential effects of continued growth and development on the water resources of Cahuilla Indian Reservation, water level, land use, and water...
Simulated effects of ground-water management alternatives for the Salinas Valley, California
E.B. Yates
1988, Water-Resources Investigations Report 87-4066
A two-dimensional digital groundwater flow model was developed to analyze the geohydrology of the groundwater basin in the Salinas Valley. The model was calibrated for steady-state and transient simulations by comparing simulated with measured or estimated inflows, outflows, and water levels for 1970-81. Preliminary estimates of hydraulic properties and some...
Hydrogeology, aquifer characteristics, and ground-water flow of the surficial aquifer system, Broward County, Florida
J.E. Fish
1988, Water-Resources Investigations Report 87-4034
The surficial aquifer system, in which an unconfined groundwater flow system exists, comprises the sediments from land surface to the intermediate confining unit (formerly called the Floridan aquiclude) in Broward County, Florida. These sediments have hydraulic conductivities that range more than seven orders of magnitude from about 0.001 ft/d to...
Hydrology and water quality of Delavan Lake in southeastern Wisconsin
S. J. Field, M.D. Duerk
1988, Water-Resources Investigations Report 87-4168
Delavan Lake is a eutrophic, recreational lake in a densely populated area of southeastern Wisconsin. Sewage effluent and septic tank drainage were diverted out of the drainage basin of the lake to improve its water quality in 1981. The worst known blue-green algal bloom occurred in the lake in the...
Water-quality data for the Boise River, Boise to Star, Idaho, October to December 1987
S.A. Frenzel, T.F. Hansen
1988, Open-File Report 88-171
Chemical and physical data were collected at six and biological data at five sites on the Boise River between Veterans Memorial Parkway in Boise and Star, Idaho, from October to December 1987. Data were collected to determine the impact of sewage effluent from two Boise wastewater treatment plants on the...
Hydrogeology and flow of water in a sand and gravel aquifer contaminated by wood-preserving compounds, Pensacola, Florida
B.J. Franks
1988, Water-Resources Investigations Report 87-4260
The sand and gravel aquifer in southern Escambia County, Florida , is a typical surficial aquifer composed of quartz sands and gravels interbedded locally with silts and clays. Problems of groundwater contamination from leaking surface impoundments are common in surficial aquifers and are a subject of increasing concern and attention....
