Altitude of water table, Biscayne Aquifer, Dade County, Florida, May 1980
Karl W. Ratzlaff
1981, Open-File Report 81-808
Average May water levels for the Biscayne aquifer in Dade County , Florida, were contoured (contour interval 1 and 2 feet) on a 1:96,000-scale map. Maps are prepared for periods of low and high water levels to provide water managers with information about water levels in Dade County and how...
Potentiometric map of the Cockfield Aquifer in Mississippi, fall, 1980
B. E. Wasson
1981, Open-File Report 81-1053
This potentiometric map of the Cockfield aquifer is the eleventh in a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources , Bureau of Land and Water Resources, delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop...
An annotated bibliography of literature on Alaska water birds
Colleen M. Handel, Margaret R. Petersen, Robert E. Gill Jr., Calvin J. Lensink
1981, FWS/OBS 81/12
The demand for information on birds in Alaska has surged within the past few years, primarily because of the need to adequately assess the impacts of a wide range of planned developments. The accompanying increase in studies of avian populations has resulted in a growing need for a comprehensive bibliography...
Potentiometric surface of the Floridan Aquifer, St. Johns River Water Management District and vicinity, Florida, May 1981
George R. Schiner, Eugene C. Hayes
1981, Open-File Report 81-1052
This map presents the potentiometric surface of the Floridan aquifer in the St. Johns River Water Management District and vicinity for May 1981. The Floridan aquifer is the principal source of potable water in the area. Water-level measurements were made in approximately 1,000 wells and at several springs. The potentiometric...
Annual summary of ground-water conditions in Arizona, spring 1979 to spring 1980
Water Resources Division, U.S. Geological Survey
1981, Open-File Report 81-906
Withdrawal of ground water, about 4.0 million acre-feet in Arizona in 1979, is about 200,000 acre-feet less than the amount withdrawn in 1978. The withdrawals in 1978 and 1979 are the smallest since the mid-1950 's except in 1966. Nearly all the decrease was in the amount of ground water...
Hydrogeochemistry and simulated solute transport, Piceance Basin, northwestern Colorado
S. G. Robson, G.J. Saulnier Jr.
1981, Professional Paper 1196
Oil-shale mining activities in Piceance basin in northwestern Colorado could adversely affect the ground- and surface-water quality in the basin. This study of the hydrology and geochemistry of the area used ground-water solute-transport-modeling techniques to investigate the possible impact of the mines on water quality. Maps of the extent and...
Petrogenetic modeling of a potential uranium source rock, Granite Mountains, Wyoming
J. S. Stuckless, A.T. Miesch
1981, Professional Paper 1225
Previous studies of the granite of Lankin Dome have led to the conclusion that this granite was a source for the sandstone-type uranium deposits in the basins that surround the Granite Mountains, Wyo. Q-mode factor analysis of 29 samples of this granite shows that five bulk compositions are required to...
Potentiometric surface of the Floridan Aquifer, Southwest Florida Water Management District, May 1981
D. K. Yobbi, W. M. Woodham, George R. Schiner
1981, Open-File Report 81-1006
A May 1981 potentiometric-surface map of the Southwest Florida Water Management District depicts the annual low water-level period. Potentiometric levels decreased 10 to 45 feet between September 1980 and May 1981 in the citrus and farming sections of southern Hillsborough, northern Hardee, southwestern Polk, northwestern DeSoto, and Manatee Counties. Water...
Potentiometric surface of the Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, September 1981
George R. Schiner, E. C. Hayes
1981, Open-File Report 82-118
This map presents the potentiometric surface of the Floridan acquifer in the St. Johns River Water Management District and vicinity for September 1981. The Floridan acquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1,000 wells and on several springs. The potentiometric...
Effects of residential wastewater treatment systems on ground-water quality in west-central Jefferson County, Colorado
Dennis C. Hall, D. E. Hillier, Edward Nickum, W.G. Dorrance
1981, Open-File Report 81-73
The use of residential wastewater-treatment systems in Evergreen Meadows, Marshdale, and Herzman Mesa, Colo., has degraded ground-water quality to some extent in each community. Age of community; average lot size; slope of land surface; composition, permeability, and thickness of surficial material; density, size , and orientation of fractures; maintenance of...
Altitude of water table, Biscayne Aquifer, Dade County, Florida, March 1979
Karl W. Ratzlaff
1981, Open-File Report 81-647
Average March water levels for the Biscayne aquifer in Dade County, Florida, were contoured (contour interval 1 and 2 feet) on a 1:96,000-scale map. Maps are prepared for periods of low and high water levels to provide water managers with information about water levels in Dade County and how they...
