EP request is an alarming threat to groundwater

By Patrick Cox

Barton Springs Edwards Aquifer District (BSEACD) was created by the Texas Legislature and overwhelmingly approved by voters in 1987. For more than 30 years, BSEACD has fulfilled its mission: conserving, preserving, protecting and recharging groundwater and has worked to promote efficiency, prevent waste, and protect our natural resources and property owners.

During the late 1980s and early 1990s, my family and I lived in the Buda area.  We worked with volunteers and local cities to create the BSEACD. I was elected to the first BSEACD Board of Directors, serving for eight years, seven of those as president. In 1996, our family moved back to Wimberley. Since then, I have been continuously involved in groundwater, conservation and natural resource issues.

In 2014, when Electro Purification Corporation (EP) planned to pump massive amounts of water from the unregulated portion of the Trinity Aquifer in Hays County, residents worked with BSEACD to bring this region under regulatory oversight. We were successful in the 2015 legislative session and BSEACD received authorization to expand its jurisdiction. Their added tasks are to protect groundwater resources, manage pumping and coordinate conservation over the Trinity Management Zones – the Upper, Middle and Lower Trinity Aquifer, that underlie the Edwards Aquifer.

Today, we are involved in another contest with EP and its plan to withdraw millions of gallons of groundwater and sell it outside of this region. In February 2018, BSEACD published the “Evaluation of the Potential for Unreasonable Impacts from the EP Well Field, Hays County, Texas.” These findings and more will be presented at the public information session at the Wimberley Community Center 6 p.m. Monday, June 18.

BSEACD board will make the final decision on the EP permit. As we proceed through the hearing and public comment process, we should focus on –

• Based on the pumping tests and the modeling in the BSEACD “evaluation” study, proposed EP wells will significantly decrease the yield or end pumping of many existing wells due to lower groundwater levels. According to the study, these conditions are “almost certain” unless “special permit conditions” are applied. How could any special conditions justify this permit?

• According to BSEACD “evaluation” report, the proposed EP pumpage will have a dramatic impact on existing water wells, especially the many older, shallower wells. Existing wells within 2 miles and potentially those beyond this range will see reduced water levels by 200 feet and possibly 500 feet combined with the likelihood of lower water quality. If this is the case, what is the impact on wells that are immediately outside of the 2-mile line and how far do the negative effects extend to these additional wells?

• If allowed, the EP permit would leave existing well owners in the 2-mile area with an insufficient volume of water. By its own rules, the district has the duty to protect property owners and conserve our groundwater. How will existing well owners be protected?

• EP must demonstrate the actual need and justify the volume the company wants to pump. If a permit is obtained for any significant volume, how will existing well owners receive meaningful mitigation for the loss of their water?

• If BSEACD approves a permit of any volume for EP, how is that going to be efficiently monitored? What will happen under drought conditions or other serious threats to the aquifer?

• BSEACD needs to be mindful to avoid “waste” of groundwater resources as defined by the Texas Water Code and district rules. Withdrawal of groundwater of this magnitude results in lower quality water. Does this requested pumpage meet the definition of waste and the test of efficient and beneficial use of our groundwater?

These issues and many others raise serious questions on the EP permit. Based on the evidence and using plain common sense, this permit request is objectionable and sets a dangerous precedent. Ultimately, even with a revised and scaled down pumpage permit, BSEACD Board of Directors should deny the EP filing based on their sworn duty to protect our groundwater for all property owners of this area.
