TEEX develops ECLOX protocols to detect toxins in drinking water

Protecting and monitoring the quality of the state's drinking water supply is the goal of a joint effort by the Texas Commission on Environmental Quality (TCEQ) and the Texas Engineering Extension Service (TEEX)—an effort aimed at detecting a variety of toxins that could contaminate a community's water supply, either accidentally or intentionally. After 9/11, many public water systems across the state and nation acquired an ECLOX field analyzer to measure drinking water contaminants.

But there was a big problem, says TEEX Water and Wastewater Laboratory Instructor Keith McLeroy: the equipment came with minimal instructions and no protocols for establishing baseline data for comparing the ECLOX readings. TCEQ turned to the TEEX Water and Wastewater Program to establish baseline data for 24 public water systems in Texas, and to develop a protocol for effectively measuring possible contaminants. Following the 2008 TCEQ project in which TEEX developed specific protocols for the ECLOX luminometer, TEEX has become recognized for its expertise in ECLOX baseline data development, protocols and training.

“We are rewriting the ECLOX protocols, which will further enhance the overall effectiveness of the ECLOX luminometer as a multi-purpose analyzer for both security and daily monitoring of drinking water," McLeroy said.
