This project will facilitate TWDB with the process of designating brackish groundwater production zones in the Rustler Aquifer, as stipulated by the 84th Texas Legislature in House Bill 30. This includes submitting a report to the Texas Legislature by December 1, 2016. Results from this study include estimates of the extent, volume, and availability of potential brackish groundwater production areas in the Rustler Aquifer.
