Water table in the surficial aquifer and potentiometric surface of the Floridan Aquifer in selected well fields, west-central Florida, September 1976
Paul D. Ryder, L. R. Mills
1977, Open-File Report 77-551
The water table in the surficial aquifer and the potentiometric surface of the Florida aquifer in a 1200 square-mile area in west-central Florida are mapped semiannually by the U. S. Geological Survey. Maps are prepared on the basis of water levels measured in wells each May to coincide with seasonal...
Geology and ground water in Door County, Wisconsin, with emphasis on contamination potential in the Silurian dolomite
Marvin G. Sherrill
1977, Open-File Report 77-61
Door County, a recreational and fruit-growing area bordering Lake Michigan in northeastern Wisconsin, has had a long history of ground-water contamination from surface and near-surface sources. Contamination is most severe in late summer when fruit-canning operations and the influx of tourists create additional wastes. Silurian dolomite is the upper bedrock...
Water resources data for Montana, water year 1976
Water Resources Division, U.S. Geological Survey
1977, Water Data Report MT-76-1
Water resources data for the 1976 water year for Montana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water-levels of wells. This report contains discharge records for 217 gaging stations; stage only records for 1 lake station;...
Geology and ore deposits of the Kutam Mine, Kingdom of Saudi Arabia
Charles W. Smith, R. Ernest Anderson, M.R. Dehlavi
1977, Open-File Report 78-519
The ancient Kutam mine in southwestern Saudi Arabia was discovered during the course of regional geologic mapping. Malachite coatings along fractures in the ancient workings and nearby large piles of slag indicate the mine was worked for copper. Quartz porphyry of Precambrian age is the principal host rock of the deposit....
Derivation of equations describing solute transport in ground water
Leonard F. Konikow, D.B. Grove
1977, Water-Resources Investigations Report 77-19
A general equation describing the three-dimensional transport and dispersion of a reacting solute in flowing ground water is derived from the principle of conservation of mass. The derivation presented is more detailed but less rigorous than derivations published previously. The general solute-transport equation relates concentration changes to hydrodynamic dispersion, convective...
Aquatic organisms from selected sites along the Trans-Alaska Pipeline corridor, September 1970 to September 1972: supplement
Jon W. Nauman, Donald R. Kernodle
1977, Open-File Report 77-634
This report is a supplement to earlier preconstruction studies of benthic invertebrates and water quality at selected sites along the trans-Alaska pipeline corridor. Some of the problems which arose during the course of data collection and analysis are discussed. Benthic invertebrate abundance and community-structure data are presented for 20 sites...
Ground-water resources of Chester County, Pennsylvania
Laurence J. McGreevy, Ronald A. Sloto
1977, Water-Resources Investigations Report 77-67
Fifty gallons per minute (3 liters per second) or more may be obtained from wells in almost all parts of the county, but not at all locations. Adequate exploration to find fracture or solution openings is required. Five hundred gallons per minute (30 liters per second) or more may be...
