Summary

The Edwards and Trinity aquifers are major sources of water for agriculture, industry, and urban and rural communities in south-central Texas. Both the Edwards and Trinity aquifers are classified as major aquifers by the State of Texas. The dissolution of the carbonate rocks composing the Edwards and Trinity aquifers results in distinctive landforms rich in both springs and karst features (caves, sinkholes, and other visible areas of solution-enlarged porosity). Previous studies such as those by the U.S. Geological Survey (USGS) and the Texas Bureau of Economic Geology (BEG) have mapped the geology, hydrostratigraphy, and structure in these areas at various scales. The purpose of this data release is to present the data that were collected [...]

Purpose

These digital data represent the geographical extent of the surficial hydrostratigraphic units and faulting within northern Bexar and Comal Counties in south-central Texas. With a rapidly increasing population placing an increasing demand on water resources, the updated mapped hydrostratigraphic units are intended to aid in identifying units that likely facilitate groundwater recharge or discharge or function as a confining layer. These digital data accompany Clark and others (2023).
