Auburn invests in technology to reduce water disinfection byproducts

In response to exceeding federal standards for disinfection byproducts in Auburn’s water system, the city council has approved a $95,445 bid for a chlorine dioxide generator to tackle the issue.

The Citizen reported the decision, which was passed at a Thursday meeting.


It follows a review by the city’s Department of Municipal Utilities, which previously used sodium hypochlorite for water disinfection and zebra mussel control.

The move was triggered by an annual average of trihalomethanes (THMs) at a city sampling location reaching 81 parts per billion (ppb), surpassing the U.S. Environmental Protection Agency’s standard of 80 ppb.
