SEGUIN-The GBRA's Port Lavaca Water Treatment Plant has completed the alternate disinfectant procedure recommended by the Texas Commission on Environmental Quality (TCEQ), the state's regulatory agency, to insure the water distribution system maintains a stable disinfectant residual throughout the summer and winter months. The use of "free chlorine" in the system for a short period of time during the summer, prevents the accumulation of ammoniated compounds that might cause problems with disinfectant testing.

"The procedure went very well, with rapid change-out of the water in all three systems we serve," according to Herb Wittliff, plant manager. "Coordination with the City of Port Lavaca, the Port O'Connor Municipal Utility District, and the Calhoun County Rural Water System insured that disinfectant residuals transitioned very quickly and remained at or near optimum readings throughout the life of the project", he added.

Chief Operator Stephanie Shelly said, "Only very few calls were fielded from customers who said the water had a slightly different taste, which is normal and to be expected. We have reverted to our normal procedure and we are utilizing chloramines again-our standard disinfectant."

The GBRA was established by the Texas Legislature in 1933 as a water conservation and reclamation district. GBRA provides stewardship for the water resources in its 10-county statutory district, which begins near the headwaters of the Guadalupe and Blanco rivers, ends at San Antonio Bay, and includes Kendall, Comal, Hays, Caldwell, Guadalupe, Gonzales, DeWitt, Victoria, Calhoun, and Refugio counties.
