Ground-water withdrawals and changes in water levels in the Houston District, Texas
During 1975-79, total withdrawals of ground water in the Houston district decreased by 9.7 percent. This percentage represents a decrease from 505 million gallons per day (22.1 cubic meters per second) during 1975, to 456 million gallons per day (20.0 cubic meters per second) during 1979. The decrease resulted from an increased use of surface water that became available from Lake Livingston on the

Hydrology of the low-level radioactive solid waste burial site and vicinity near Barnwell, South Carolina
Geologic and hydrologic conditions at a burial site for low-level radioactive waste were studied, and migration of leachates from the buried waste into surrounding unconsolidated sediments were evaluated. The burial site and vicinity are underlain by a sequence of unconsolidated sediments of Late Cretaceous, Tertiary, and Quaternary age. These sediments are deposited over a graben which has been f

Development of ground-water resources in Orange County, Texas, and adjacent areas in Texas and Louisiana, 1971-80
Pumpage in Orange County from the lower unit of the Chicot aquifer averaged 21.2 million gallons per day (0.93 cubic meter per second) and pumpage from the upper unit of the Chicot averaged about 2 million gallons per day (0.088 cubic meter per second) from 1971-79. Annual pumpage increased in municipal areas and decreased in industrial areas with little net change in total annual pumpage during t

Water quality of Lake Granbury, north-central Texas
During water years 1970-79, the concentrations of the major dissolved constituents in Lake Granbury on the Brazos River in north-central Texas averaged about 1,800 milligrams per liter of dissolved solids, 700 milligrams per liter of chloride, and 350 milligrams per liter of sulfate. The water was generally very hard (hardness as calcium carbonate greater than 180 milligrams per liter). The concen

Hydrologic data for urban studies in the Houston, Texas, metropolitan area, 1979
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, Houston, and San Antonio.The U.S. Geological Survey, in cooperation with the city of Houston, began studies in the Houston metropolitan area in 1964. The program was expanded in 1968 to include collection of water-quality data. The objectives of the Housto

Digital model evaluation of the predevelopment flow system of the Tertiary limestone aquifer, Southeast Georgia, Northeast Florida, and South South Carolina
A computer model using finite-difference techniques was used successfully to simulate the predevelopment flow regime within the multilayered Tertiary limestone aquifer system in Southeastern Georgia, Northeastern Florida, and Southern South Carolina as part of the U.S. Geological Survey 's Tertiary Limestone Regional Aquifer System analysis. The aquifer, of early Eocene to Miocene age, ranges from

Water quality of Canyon Lake, central Texas
The volume-weighted average concentrations of the principal dissolved constituents in Canyon Lake on the Guadalupe River in central Texas are usually less than 240 milligrams per liter of dissolved solids, 20 milligrams per liter of chloride, and 30 milligrams per liter of sulfate. The water, which is very hard, has a volume-weighted average concentration of hardness of about 200 milligrams per li

Ground-water withdrawals and land-surface subsidence in the Houston-Galveston region, Texas, 1906-80
The withdrawal of larqe amounts of ground water in the Houston-Galveston region, Texas, has resulted in water-level declines of as much as 250 feet (76 meters) in wells completed in the Chicot aquifer and as much as 300 feet (91 meters) in wells completed in the Evangeline aquifer during 1943-77. Since late 1976, changes in pumping distribution resulting from efforts to control subsidence and the

Organochlorine residues in fish: National Pesticide Monitoring Program, 1970-74
As part of the National Pesticide Monitoring Program, the U.S. Fish and Wildlife Service analyzed organochlorine contaminant residues in fish samples collected from about 100 stations each year from 1970 to 1974. During this period, mean residues of DDT and its metabolites declined nationally but remained widespread, and high concentrations continued to be present in areas where DDT use was extens

The freshwater‐inflow‐to‐estuaries issue
Over 55% of the United States commercial fish and shellfish catch is dependent upon estuaries for spawning and nursery functions, but estuaries cannot function ecologically without an adequate supply, seasonal inflow, and quality of freshwater from inland rivers. Such inland river development projects as constructing reservoirs, leveeing rivers, dredging navigation channels, and diverting water fo
