SWNTX response to the reply from Sara R. Thornton to Chris Nidel sent on Feb. 13, 2019:
First and foremost, Safer Water, North Texas (SWNTX) is pleased to see that North Texas Municipal Water District (NTMWD) began implementing new monthly disinfection by-product (DBP) testing in December. We will be eagerly following the results of these tests along with tests run independently by member cities such as Plano and Frisco. This additional information is vital for the education of consumers who want to understand how DBP levels are impacted during the chlorine burn so they can make informed decisions for themselves and their families. We sincerely thank the cities that have chosen to run additional tests and make the results available to their customers.
Unfortunately, some of the concerns expressed by our attorney remain unaddressed:
• Will the water district’s new, monthly tests be considered “official”, with those results being submitted to the Texas Commission on Environmental Quality (TCEQ) and included in the annual Consumer Confidence Reports that are shared with North Texas citizens?
• Our letter was addressed to both NTMWD and the TCEQ. We have yet to receive a response from the TCEQ regarding how avoiding Stage 2 DBP monitoring during chlorine burns is legally or ethically justifiable, as Texas Administrative Code mandates that “All systems must monitor during month of highest disinfection byproduct concentrations.” SWNTX looks forward to receiving more complete, and timely, responses from both the NTMWD and the TCEQ, regarding these pertinent issues.
