White River Municipal Water District Is A Superior Water System

A Source Water Assessment for your drinking water source(s) is currently being conducted by the TCEQ and should be provided to us this year. The report will describe the susceptibility and types of constituents that may come into contact with your drinking water source based on human activities and natural conditions. The information in this assessment will allow us to focus our source water protection strategiesWhite River Municipal Water District currently has a 40/30 Wavier for TTHMs and HAA5s.

White River MWD received this waiver in 2007 and there is no expiration date as long as the TTHM and HAA5 MCLs are not exceeded. White River MWD uses Chlorine Dioxide as primary disinfectant and Chloramines and secondary disinfectant to prevent excessive TTHMs and HAA5s.
