Presentation to focus on local water issues

Central Texas’ water supply faces numerous potential threats, especially as more new residents flock to the area. The League of Women Voters-Comal Area is hosting a presentation, “Water Quality in Comal County: Potential Threats?” on Wednesday night at 7 p.m. at the Tye Preston Memorial Library in Canyon Lake. The event is free and open to the public.

Annalisa Peace, executive director of the Greater Edwards Aquifer Alliance, will present the alliance’s most recent data regarding possible threats to water quality in areas where wastewater is being discharged onto karst features in Comal County.

“We believe that the growth in Comal County does have the potential to negatively impact the quality of both surface and groundwater supplies,” Peace said. “And we are very concerned about the additional impervious cover that comes from converting farm and ranch lands into high-density development. Contributing to the growing pains in the Hill Country is that the Texas Commission for Environmental Quality does not adequately consider cumulative impacts when issuing waste water discharge permits and approving stormwater plans.”

The Greater Edwards Aquifer Alliance is mapping the locations of stormwater and wastewater permits in Comal County to track potential water quality problems in the Edwards and Trinity aquifers, both of which are significant drinking water sources for Central Texas.

“The Edwards Aquifer is a uniquely prolific aquifer characterized by rapid groundwater recharge and rapid open channel flow,” Peace said. “Little to no filtration is provided as water enters directly into the Aquifer through faults, stream beds, and terrain characterized by uniquely porous Edwards limestone.  It is estimated that up to 75-80 percent of recharge occurs when streams and rivers cross the permeable formation and go underground.  Therefore, we are extremely concerned about the number of new Texas Pollutant Discharge Elimination System permits, which allow discharge of sewage effluent directly into creeks and streams, being issued in Comal County.”

Roxanna Deane, president of the League of Women Voters-Comal Area, said the public meeting is part of the group’s study of land use issues.

The Tye Preston Memorial Library is located at 16311 S. Access Rd. For more information on the presentation, visit
