This map shows the location and potential well yields of unconsolidated aquifers in the Hudson-Mohawk region at a scale of 1:250,000. It also delineates segments of aquifers that are heavily used by community water systems and designated by the New York State Department of Environmental Conservation as ' Primary Water Supply ' aquifers, and cites published reports that give detailed information on

Water-use data are essential for managing the State's limited water resources. The New Mexico State Engineer Office (NMSEO) and the U.S. Geological Survey collect and publish data on water use at 5-year intervals. These data are used by Federal and State agencies, city and county planners, private industry, and irrigation districts. This report graphically summarizes water-use data by county in Ne

This report presents July 1988 water quality data, principally dissolved nitrite plus nitrate (as nitrogen), and depth-to-water measurements for 60 wells in the Fort Hall Indian Reservation north of Pocatello, southeastern Idaho. Nitrogen concentrations ranged from 0.7 to 24 mg/L; the median concentration was 3.1 mg/L. Nitrogen concentrations in 11 samples exceeded the U. S. Environmental Protecti

Two maps show water levels in wells in the Houston, Texas, area in the Chicot aquifer and the Evangeline aquifer, spring 1988. Both the Chicot and the Evangeline aquifers are composed of several sand layers with different potentiometric surfaces. These maps, however, show approximations of single potentiometric surfaces that represent composite hydraulic heads. (USGS)

This report, which was prepared in cooperation with the city of Houston and the Harris-Galveston Coastal Subsidence District, presents data on water-level changes in the Chicot and Evangeline aquifers.

The Floridan aquifer system is one of the major sources of ground-water supplies in the United States. This highly productive aquifer system underlies all of Florida, southern Georgia, and small parts of adjoining Alabama and South Carolina, for a total area of about 100,000 square miles. About 3 billion gallons of water per day is withdrawn from the aquifer for all uses, and, in many areas, the F

Amounts of water withdrawn and consumptively used for irrigation and other uses on the Snake River Plain were estimated to help deter- mine hydrologic effects of ground- and surface-water use. Irrigation is the largest off stream use of water on the plain. Surface-water irriga- tion began in the 1840's and increased rapidly through the early 1900's. Use of ground water for irrigation accelera
