Bromide Discharges from Power Plants: a Safe Drinking Water Act/Clean Water Act Integration Story

A case study of collaboration by Clean Water Action, American Water Works Association (AWWA), Rural Community Assistance Partnership (RCAP), and the Association of Metropolitan Water Agencies (AMWA)

In September, the U.S. Environmental Protection Agency (EPA) published a final Clean Water Act (CWA) rule to update technology-based limits on steam electric power plant wastewater discharges to our nation’s water. Coal plants in particular are responsible for discharges of metals, nutrients and other contaminants into waters of the United States. Some coal plants discharge significant quantities of bromide, which if discharged near public water system intakes can lead to disinfection byproduct formation during treatment. Even small quantities of bromide in raw water can have significant health impacts (Regli et al. 2015). This is a textbook case of the potential for a CWA program to impact a Safe Drinking Water Act program.
