Sublethal Whole Effluent Toxicity (WET) Limit Implementation

The U.S. Environmental Protection Agency (EPA) is requiring the Texas Commission on Environmental Quality (TCEQ) to implement permit requirements for sublethal whole effluent toxicity (WET) limits. Implementation of such limits will expose Texas communities to significant and unnecessary expenses without demonstrated environmental benefits.

The WET Coalition was formed in 2010 by WEAT, Texas Association of Clean Water Agencies (TACWA), Texas Water Conservation Association (TWCA) and the Texas Section of the American Water Works Association (TAWWA). This Coalition has been engaged in stakeholder meetings and discussions with TCEQ and EPA regarding the implementation of WET limits in Texas wastewater permits.
