Hydrogeologic data from a study of the freshwater zone/salinewater zone interface in the Edwards Aquifer, San Antonio region, Texas
The highly productive freshwater zone of the Edwards aquifer in the San Antonio region (fig. 1) is the sole-source water supply for more than 1 million people. A transitional interface exists between the freshwater zone and the downdip, salinewater zone. A 1,000 mg/L (milligrams per liter) dissolved solids-concentration contour defines an arbitrary boundary -between the freshwater zone and the sal

Potentiometric surface of the upper Floridan aquifer in Florida and in parts of Georgia, South Carolina, and Alabama, May 1985
A map, constructed as a part of the Floridan Regional Aquifer-System Analysis (RASA), shows the potentiometric surface of the Upper Floridan aquifer for May 1985. It is based on measurements of water level or artesian pressure made in about 2 ,500 wells during the period May 13 to 24, 1985. Only measurements from tightly cased wells open exclusively to the Upper Floridan aquifer were used to make

Water movement in the unsaturated zone at a low-level radioactive-waste burial site near Barnwell, South Carolina
Four unsaturated zone monitoring sites and a meteorologic station were installed at the low level radioactive waste burial site near Barnwell, South Carolina, to investigate the geohydrologic and climatologic factors affecting water movement in the unsaturated zone. The study site is located in the Atlantic Coastal Plain. The unsaturated zone consists of a few centimeters to > 1 m of surface sand,

Water resources activities, Georgia District, 1986
The U.S. Geological Survey, through its Water Resources Division , investigates the occurrence, quantity, quality, distribution, and movement of the surface and underground water that composes the Nation 's water resources. Much of the work is a cooperative effort in which planning and financial support are shared by state and local governments and other federal agencies. This report contains a br

Iowa ground-water quality
The population served by ground-water supplies in Iowa (fig. L4) is estimated to be about 2,392,000, or 82 percent of the total population (U.S. Geological Survey, 1985, p. 211). The population of Iowa is distributed fairly uniformly throughout the State (fig. IB), with 59 percent residing in rural areas or towns of less than 10,000 (U.S. Bureau of the Census, 1982). Surficial aquifers, the Jordan

Records of wells, drillers' logs, water-level measurements, and chemical analyses of ground water in Harris and Galveston counties, Texas, 1980-84
Information on major new water wells in Harris and Galveston Counties was compiled by the U.S. Geological Survey from 1980 to 1984. This report presents the results of the hydro!ogic data collection on new large-capacity and other selected wells, including well location and completion data, drillers 1 logs of the strata penetrated, water levels, and chemical quality of the produced water. These wa
