A sediment suspension system for bioassays with small aquatic organisms
Exposure of aquatic organisms to suspended sediments can impair growth and survival and increase bioaccumulation of sediment-associated contaminants. However, evaluation of the effects of suspended sediments and their associated contaminants on aquatic organisms has been hampered by the lack of a practical and inexpensive exposure system for conducting bioassays. We present a cost-effective system

Water quality of the Edwards Aquifer and streams recharging the aquifer in the San Antonio region, Texas
The Edwards aquifer in south-central Texas is one of the most productive and most important aquifers in the State, with an average annual discharge of about 608,000 acre-ft of water during 1932-82 (Reeves and Ozuna, 1985). The Edwards aquifer is the principal source of water for municipal, industrial, and irrigation use in all or parts of five counties- Bexar, Comal, hays, Medina, and Uvalde- and

Hydrogeologic maps of the central Oklahoma aquifer, Oklahoma
This report presents hydrogeologic maps of the Central Oklahoma aquifer. The maps were prepared by measuring water levels in wells during the winder of 1986 and 1987; examination of geophysical logs to determine the altitudes of the top of selected geologic units and the base of fresh ground water; and compilation of existing information on the stratigraphy of selected geologic units and the base

Water resources data, Texas, water year 1991; Volume 2. San Jacinto River basin, Brazos River basin, San Bernard River basin, and intervening coastal basins
The Water Resources Division of the U.S. Geological Survey, in cooperation with Federal, State, and City agencies, obtains a large amount of data pertaining to the water resources of Texas each water year. Such data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water resources of the State. To make these data readily available

Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990
The Edwards aquifer is the principal source of freshwater for municipal, domestic, and industrial users in the Georgetown area. Other sources of freshwater are Lake Georgetown and the streams draining the San Gabriel River basin. Lake Georgetown, located on the North Fork San Gabriel River west of Georgetown, is a freshwater supply for some municipalities in the area. Water in the San Gabriel R

Approximate changes in water levels in wells completed in the Chicot and Evangeline aquifers, 1977-92 and 1991-92, and measured compaction, 1973-91, in the Houston-Galveston region, Texas
This report is one in a series of reports that depict water-level changes since 1977 and compaction of subsurface material since 1973. The report was prepared in cooperation with the Harris-Galveston Coastal Subsidence District and the City of Houston, and presents maps showing the approximate changes in water-levels in wells completed in the Chicot and Evangeline aquifers, 1977-92 and 1991-92 (f
