The Edwards and Trinity aquifers are major sources of water in south-central Texas and are both classified as major aquifers by the State of Texas. The population in Hays and Comal Counties is rapidly growing, increasing demands on the area's water resources. To help effectively manage the water resources in the area, refined maps and descriptions of the geologic structures and hydrostratigraphic units (HSUs) of the aquifers are needed. This digital map database presents the detailed 1:24,000-scale bedrock hydrostratigraphic map as well as names and descriptions of the geologic and hydrostratigraphic units of the Driftwood and Wimberley 7.5-minute quadrangles in Hays and Comal Counties, Tex. These digital data...

Between 2012 and 2015, water-quality samples were collected by the USGS in cooperation with the Clearwater Underground Water Conservation District (CUWCD), the Bell County Adaptive Management Coalition (BCAMC), and other entities, with a primary goal of characterizing the groundwater resources in Bell County, Texas. Water resources associated with the northern segment of the Edwards aquifer near the Village of Salado were of primary interest, but water resources in the Trinity aquifer were also investigated to a lesser degree (the assessment focused on a springs complex in the Village of Salado). Data associated with other water quality samples collected by the USGS in Bell County during 1978 to 2017, outside of...
In cooperation with the San Antonio Water System, continuous and discrete water-quality data were collected from groundwater wells completed in the Edwards aquifer, Texas, 2014-2015. Discrete measurements of nitrate were made by using a nitrate sensor. Precipitation data from two sites in the National Oceanic and Atmospheric Administration Global Historical Climatology Network are included in the dataset. The continuous monitoring data were collected using water quality sensors and include hourly measurements of nitrate, specific conductance, and water level in two wells. Discrete measurements of nitrate, specific conductance, and vertical flow rate were collected from one well site at different depths throughout...

IMPORTANT NOTE: A more recent version of this data release is available from this link. The Edwards aquifer in south central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water for recreational activities, businesses, and downstream users, and provide habitat for several threatened or endangered species. The areas pertinent to the recharge process are the catchment area and the recharge zone. The catchment area...
