Brackish Resources Aquifer Characterization System (BRACS)
In 2003, a TWDB-funded study laid the foundation for determining brackish groundwater volumes and estimated Texas has approximately 2.5 billion acre-feet of brackish groundwater. However, the study was by design regional in scope, limited in a real extent, and narrow in its assessment of groundwater quality. In 2009, the 81st Texas Legislature, approved funding to implement the Brackish Resources Aquifers Characterization System (BRACS) program to more thoroughly characterize the brackish aquifers. In 2015, the 84th Texas Legislature passed House Bill 30, directing the TWDB to identify and designate brackish groundwater production zones in the state. The 86th Texas Legislature also passed Senate Bill 1041 that extended the deadline to complete zone designations from December 1, 2022, to December 1, 2032, and House Bill 722 that established a permitting framework for developing water supplies from TWDB-designated brackish groundwater productions zones.
