Recharge zone of the Edwards aquifer hydrologically associated with Barton springs in the Austin area, Texas
Diana L. Slagle, Ann F. Ardis, Raymond M. Slade Jr.
1986, Water-Resources Investigations Report 86-4062
The Edwards aquifer extends in a narrow belt from Bell County in the northeast to Kinney County in the southwest (index map) and provides water for at least nine counties in south-central Texas. Hydrologic boundaries divide the Edwards aquifer in the Austin area for which Barton Springs is the major...
Generalized potentiometric surface of the Catahoula aquifer in central Louisiana, 1980
Angel Martin Jr., Charles D. Whiteman Jr.
1986, Water-Resources Investigations Report 86-4059
Generalized contours of the altitude of water levels in wells completed in the Catahoula aquifer in central Louisiana, are illustrated by this map. Most water level measurements used in compiling the map were made in 1980; however, in parts of the State where water levels from 1980 were unavailable and...
Surficial geology and ground-water availability in the Allegheny River basin and part of the Lake Erie basin, New York
Michael H. Frimpter
1986, Water-Resources Investigations Report 86-4041
New York State 's need to develop a groundwater management program for protection of its aquifers led in 1985 to a cooperative program between the U.S. Geological Survey and the New York State Department of Environmental Conservation (through regional planning agencies) to publish data from previous studies. The two maps...
Configuration and hydrology of the Pre-Cretaceous rocks underlying the southeastern Coastal Plain aquifer system
Robert L. Wait, Marvin E. Davis
1986, Water-Resources Investigations Report 86-4010
An investigation was conduced to define the configuration and hydrology of the rock surface upon which the sand aquifers and confining beds of the Southeastern Coastal Plain aquifer system were deposited. The base of the Southeastern Coastal Plain aquifer system consists of crystalline rocks, saprolite, Paleozoic rocks, Triassic sedimentary rocks...
Statistical summary and evaluation of the quality of surface water in the Colorado River basin, 1973-82 water years
Freeman L. Andrews, Terry L. Schertz
1986, Water-Resources Investigations Report 85-4181
Significant upward trends in dissolved-solids concentrations were detected with the Seasonal Kendall Test for trends at three stations in the upper basin during the study period. The increases exceeded 270 milligrams per liter per year at two stations and 165 milligrams per liter per year at the third station. The composition...
Water level and saturated thickness maps of the alluvial aquifer in eastern Arkansas, 1984
Maria Plafcan, Joe Edds
1986, Water-Resources Investigations Report 86-4014
The Mississippi River Valley alluvial aquifer, is a major source of water for most of eastern Arkansas. Agriculture is largely dependent on the aquifer as approximately 3.3 billion gallon per day are withdrawn for that purpose. Much smaller withdrawals also occur for industrial, public supply, and domestic use. The purpose...
Ground-water availability in the Genesee River Basin, New York and Pennsylvania
John C. Kammerer, William A. Hobba Jr.
1986, Water-Resources Investigations Report 86-4048
New York State 's need to develop a groundwater management strategy for the protection of its aquifers led, in 1985, to a cooperative program between the U.S. Geological Survey and the New York State Department of Environmental Conservation, through the Genesee/Finger Lakes Regional Planning Council, to publish basinwide groundwater availability...
