Chemical and bacteriological quality of water at selected sites in the San Antonio area, Texas, August 1968-January 1975 Chemical and bacteriological quality of water at selected sites in the San Antonio area, Texas, August 1968-January 1975

Urban development on or adjacent to the recharge zone of the Edwards aquifer is causing concern about the possible pollution of ground water in the aquifer, which is the principal source of water supply for the San Antonio area. Water-quality data for many wells and springs and for selected sites on streams that cross the recharge zone of the aquifer are being collected to provide...

Summary appraisals of the nation's ground-water resources–Texas-Gulf region Summary appraisals of the nation's ground-water resources–Texas-Gulf region

Ground water in the Texas-Gulf Region is a large and important resource that can provide a more significant percentage of the total water supply of the region. Total water requirements within the region are projected to rise sharply from 14 million acre-feet (17 cubic kilometres) in 1970 to nearly 26 million acre-feet (32 cubic kilometres) in 2020. About half of the water used in 1970...

Ground-water resources of Wilson County, North Carolina Ground-water resources of Wilson County, North Carolina

The most important sources of ground water for Wilson County, North Carolina are (1) the sand beds of the Cretaceous aquifer system in the Coastal Plain section in the eastern part of the county and (2) the bedrock aquifer system in the Piedmont section in the western part of the county. The Cretaceous aquifer is recharged from leakage through overlying beds composed primarily of clay...

Magnitude and frequency of floods in North Carolina, technique for estimating the magnitude and frequency of floods on natural streams in North Carolina Magnitude and frequency of floods in North Carolina, technique for estimating the magnitude and frequency of floods on natural streams in North Carolina

Methods are provided to estimate the magnitude and frequency of floods on natural North Carolina streams with drainage areas greater than 0.5 square mile (1.3 square kilometers). For 257 gaged sites, the magnitudes of floods having recurrence intervals from 2 to 100 years are provided in tables. For ungaged sites, equations, graphs, and maps allow estimation of flood magnitudes. Multiple

Digital model for simulated effects of ground-water pumping in the Hueco Bolson, El Paso Area, Texas, New Mexico, and Mexico Digital model for simulated effects of ground-water pumping in the Hueco Bolson, El Paso Area, Texas, New Mexico, and Mexico

The Hueco Bolson provides a substantial part of the municipal and industrial water supply of the El Paso area of Texas, New Mexico, and Mexico. Although the supply 6f fresh ground water in the bolson is large, about 10.6 million acre-feet (13,070 hm3) in 1973 in the Texas part of the bolson alone, the supply is being depleted. A two-layer digital model of the Hueco Bolson was developed...

Salt-water encroachment in aquifers near the Houston Ship Channel, Texas Salt-water encroachment in aquifers near the Houston Ship Channel, Texas

Interpretations based on analyses of inorganic constituents, dissolved organic carbon, and tritium in ground water and surface waters indicate that the Houston Ship Channel is the source of salt water that has been detected in shallow wells between Baytown and Houston, Texas. Analyses of the ratios of the stable isotopes of carbon, sulfur, hydrogen, and oxygen were inconclusive as to the...
