Protect the Trinity Aquifer from Over Pumping

In 2015, Electro Purification sparked outrage in Hays County with plans to pump five million gallons of groundwater a day from an unregulated portion of the Trinity Aquifer in Driftwood. Although the area is now regulated by the Barton Springs Edwards Aquifer Authority, Electro Purification is still planning on pumping a tremendous amount of water from the Trinity-possibly 2.5 million gallons a day. The company is currently conducting aquifer testing. You can read more about the testing in this recent report by KXAN.

The Trinity Aquifer is already declining. A monitor well located near the city of Wimberley shows a water-level decline of approximately 40 feet between March, 1999, and July, 2016. Jacob’s Well, which feeds Cypress Creek and the Blanco River, flowed through the 1950’s drought of record, yet it has stopped flowing several times in the last decade due to droughts and over-pumping.

Yet more and more groundwater will be pumped from the Trinity Aquifer in the future. In the near future, Electro Purification will apply to BSEACD for a huge groundwater production permit. Needmore Water LLC has applied to BSEACD for a permit to produce 289,080,000 gallons a year from the Trinity Aquifer. And the Hays Trinity GCD anticipates that there will be more and more applicants seeking groundwater permits to accommodate growth in Dripping Springs.

Groundwater laws in Texas force groundwater districts to manage the depletion of aquifers. TESPA is developing a long term protection strategy to protect not only the springs and groundwater across Hays County but more generally for the Texas Hill Country.

The Conservation Amendment of the Texas Constitution says that the public has rights in surface and groundwater, and that state governments like groundwater districts have a duty to conserve the natural resources of the state.

TESPA is committed to ensuring that the State and local groundwater districts do not overlook their Constitutional duty to protect the Trinity Aquifer in the face of pressure to develop groundwater resources.

Please consider making an end of the year donation to TESPA so that we can continue to fight to protect the Trinity Aquifer from over pumping.
