PFLUGERVILLE, Texas (KXAN) — Chlorinated water was discharged into Gilleland Creek through a storm drain on Tuesday by crews working at a pump station. The City of Pflugerville is currently constructing a new half-million-gallon storage tank at a pump station at the corner of Pfennig Lane and Black Locust Drive, and crews had filled the new tank with water and a high concentration of chlorine before putting it into operation. City officials said the water was then dumped down the drain before the water was dechlorinated, which is against standard procedure.
“Fortunately the entire half-million-gallon tank was not released into Gilleland Creek because staff noticed the strong odor,” said Assistant City Manager Tom Word.
City officials said they received several calls about dead fish in the creek shortly after the 10 a.m. incident. City workers were then stationed along creek banks to keep people out of the water. As of 1:45 p.m., the city said chlorination levels in the creek measured 4 parts per million, a drinking water standard.
City officials were working to notify the Texas Commission on Environmental Quality of the spill and are reviewing procedures with city inspectors and the contractor to make sure similar incidents do not happen in the future. The pump serves residents in the western part of Pflugerville and went online in July 2009.
