The mission of The Trinity Edwards Springs Protection Association (TESPA) is to protect the Trinity and Edwards aquifers from over pumping, the springs that flow from this interconnected system, and the property rights of landowners who depend on and wish to conserve this precious natural resource.

The Trinity Aquifer is under siege. The springs and creeks which emanate from this natural resource, and the property rights of landowners are at risk. Today, more than ever before, this precious natural resource, which is vital to the ecology and economy of the Hill Country, is in peril. As the population in Central Texas continues to grow, water suppliers are searching for new sources of water, and the Trinity Aquifer is a target. Although groundwater pumping from the aquifer is already occurring at an unsustainable rate, more groundwater development projects are in the works. Current groundwater law facilitates the mining of our aquifers and elevates groundwater development over groundwater protection. TESPA is taking legal action and advocating for policy changes to ensure that groundwater in Texas is sustainably managed and landowners' property rights are protected.

Impacts of the EP Permit

When: May 29th at 7:00 PM

Where: Saint Stephens Church, 6000 FM3237, Wimberley, TX 78676

TESPA will be holding a follow up meeting after the Barton Springs Edwards Aquifer Conservation District issues its preliminary decision on Electro Purification's permit application to pump 2.5 million gallons of groundwater a day from the Middle Trinity Aquifer near Driftwood and Wimberley. We intend to briefly discuss the preliminary decision, answer questions, and discuss a path forward.

As we discussed at the May 15th meeting, BSEACD projects that pumping this amount of groundwater will cause 300-500 feet of drawdown in the Cow Creek Aquifer within one year and after seven years could result in dewatering of the Cow Creek Aquifer. BSEACD is currently reviewing EP's application.

Please attend this meeting to learn how your groundwater resources will be impacted and what we can do to protect the Trinity Aquifer.
