Water-quality conditions and an evaluation of ground- and surface-water sampling programs in the Livermore-Amador Valley, California
S. K. Sorenson, P. V. Cascos, R. L. Glass
1985, Water-Resources Investigations Report 84-4352
A program to monitor the ground- and surface water quality in the Livermore-Amador Valley has been operated since 1976. As of 1982, this monitoring network consisted of approximately 130 wells, about 100 of which were constructed specifically for this program, and 9 surface water stations. Increased demand on the groundwater...

1985, Open-File Report 85-8
Geochemical reconnaissance for rare metals in plutons of albite-muscovite granite and quartz monzonite in the vicinity of Jabal Lababa disclosed positive geochemical anomalies for beryllium, tantalum, thorium, lanthanum, niobium, tin, yttrium, and zirconium. The low anomalous values for the rare metals in rocks and the short mechanical dispersion trains, seldom...

Use of double-mass curves to determine drawdown in a long-term aquifer test in north-central Volusia County, Florida
A. T. Rutledge
1985, Water-Resources Investigations Report 84-4309
A test well withdrew water from the upper Floridan aquifer system at an average of 530 gallons per minute from June 1978 to July 1979. Ground-water levels were monitored in wells open to the upper Floridan (artesian) aquifer system and in wells open to the surficial (water-table) aquifer. Double-mass curves...

Ground-water hydrology of Volusia County, Florida, with emphasis on occurrence and movement of brackish water
A. T. Rutledge
1985, Water-Resources Investigations Report 84-4206
Brackish water is present in the eastern and western fringes of Volusia County, Florida in the surficial aquifer and in the Floridan aquifer system. Average pumpage in 1980 in Volusia County was 66 million gallons per day. Water levels in the Floridan aquifer system declined more than 10 feet over...
Ground-water data from the San Miguel River basin, southwestern Colorado
D. J. Ackerman, T.D. Brooks
1985, Open-File Report 85-191
Hydrologic data were collected from 36 wells and 80 springs in the San Miguel River basin from 1977 to 1979. Depth to water was measured for 22 wells and discharges were measured for 53 springs. Chemical analyses for water samples collected from 23 wells and 25 springs indicated larger dissolved...
Potential impacts of discharging tertiary-treated wastewater into Port Royal Sound, South Carolina
G. K. Speiran, D.L. Belval
1985, Water-Resources Investigations Report 85-4326
An assessment of physical characteristics of Port Royal Sound was combined with the results of a dye tracer study and with data collected from a previous environmental study to describe the impact on the water quality from discharging tertiary treated wastewater into the sound. Calculated velocities for the time of...
Effects of high-rate wastewater spray disposal on the water-table aquifer, Hilton Head Island, South Carolina
G. K. Speiran
1985, Water-Resources Investigations Report 84-4291
A study by the U.S. Geological Survey from April 1982 through December 1983 evaluated the effects of high-rate disposal of treated wastewater on the water table aquifer, Hilton Head Island, South Carolina. Flooding of topographically low areas resulted from the application of 10.8 inches of wastewater in 10 days in...
Potentiometric surface of the upper Floridan Aquifer, west-central Florida, May 1985
G. L. Barr
1985, Open-File Report 85-482
A May 1985 potentiometric surface map of the Upper Floridan aquifer in west-central Florida depicts the annual low water-level period. Most areas of west-central Florida were experiencing drought conditions and water levels were at or approaching near-record low levels. Water levels in most wells measured in May 1985 were lower...

Estimated public-water supply and industrial-commercial ground-water withdrawals and returns in Nassau County, Long Island, New York, 1973-79
D. S. Snavely, J. F. Williams
1985, Water-Resources Investigations Report 84-4246
Nassau County, New York depends upon ground water for its freshwater supply. The primary water uses are for public-water supply and industrial-commercial purposes, which together accounted for 202 Mgal/d (million gallons per day) in 1975. Public-water suppliers withdrew 85 percent of their water from the Magothy Formation. About 133 Mgal/d...

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...

J.D. Stoner
1985, Water-Resources Investigations Report 85-4084
Reported water withdrawals in Oklahoma during 1982 were 1,270.64 million gallons per day. The withdrawals were about equally distributed between ground water and surface water with 46 percent being ground water and 54 percent being surface water. In general, the western counties rely on ground water and the eastern counties...
