Stories in Texas. TNC has helped protect more than , acres of land above the Edwards Aquifer, which is one of the most important water resources in Texas.
November 11, The Edwards Aquifer is one of the most important water resources in Texas. Its waters feed springs, rivers and lakes and sustain diverse plant and animal life, including rare and endangered species. The Edwards Aquifer stretches beneath 12 Texas counties and the land above it is broken into four primary regions.
Once in a while I look at my hit counts. Otherwise, I do not collect or use any information about your surfing habits on any of these pages.

Park Passes. Technical Announcements. Employees in the News. Emergency Management. Survey Manual. The Edwards aquifer in south-central Texas is one of the most productive aquifers in the Nation and is the primary source of water for the rapidly growing San Antonio area. Springs issuing from the Edwards aquifer provide habitat for several threatened and endangered species, serve as locations for recreational activities, and supply downstream users.

The competition for ground water from the Edwards aquifer has created some controversial water issues in central Texas. Designated a sole-source aquifer in the San Antonio and Austin areas by the U. Environmental Protection Agency , the aquifer is critical to farming and ranching economies west of San Antonio and recreational economies northeast of the city. Comal and San Marcos Springs and their effluent streams rivers support seven Federally listed endangered and one threatened species.

The Texas Water Development Board classifies the karstic Edwards and Trinity aquifers as major sources of water in south-central Texas. To effectively manage the water resources in the area, detailed maps and descriptions of the geology framework and hydrostratigraphic units of the aquifers in Hays County, Tex. The effects of urbanization across the recharge zone in Bexar County and potential impact on the water quality in the Edwards aquifer is a topic of specific concern for the City of San Antonio.
TXWSC is simultaneously collecting water-quality data from surface-water runoff sites and paired shallow groundwater wells within the recharge zone of the Edwards aquifer to better characterize the water quality connection between surface water and groundwater.
More comprehensive and integrated information will improve the understanding of aquifer water quality and establish a baseline for measuring future water-quality changes. The USGS Texas Water Science Center is simultaneously collecting water-quality data from surface-water runoff sites and paired shallow groundwater wells within the recharge zone of the Edwards aquifer To effectively manage the water resources in the area, detailed maps and descriptions of the geologic framework and hydrostratigraphic units of the aquifers in Hays County, Texas are needed.
The USGS Texas Water Science Center is implementing a more complete and integrated monitoring network for the Edwards aquifer to improve the understanding of aquifer water quality and establish a baseline for measuring future water-quality changes.
