BRACS Yegua-Jackson Aquifer Study
Study Summary:
The TWDB contracted with INTERA Incorporated to map the Yegua-Jackson Aquifer.
The goals of the study are to (1) map and characterize the brackish parts of the major and minor aquifers of the study area in greater detail using existing water well reports, geophysical well logs, and available aquifer data and (2) build datasets that can be used for groundwater exploration and replicable numerical groundwater flow models to estimate aquifer productivity.
The study area includes all or portions of the following counties: Angelina, Atascosa, Austin, Bee, Brazos, Burleson, Colorado, DeWitt, Duval, Fayette, Gonzales, Grimes, Houston, Jasper, Jim Hogg, Karnes, La Salle, Lavaca, Lee, Live Oak, Madison, McMullen, Montgomery, Nacogdoches, Newton, Polk, Sabine, San Augustine, San Jacinto, Starr, Trinity, Tyler, Walker, Waller, Washington, Webb, Wilson, and Zapata.
The objectives of the study are to:
- collect, analyze, and interpret water well and geophysical well logs;
- map the geological boundaries of the Yegua-Jackson;
- map the distribution of total dissolved solids in the aquifer;
- map the distribution of key chemical parameters of interest to desalination;
- map the net sand distribution in the aquifer;
- estimate the volume of fresh and brackish groundwater in the aquifer;
- incorporate newly created information into the publicly available BRACS Database and study GIS datasets;
- prepare and publish study findings in a TWDB report.
