Tulsa Using New Drinking Water Treatment Disinfectant, City Says

Tulsa and the Metropolitan Utility Authority are treating Tulsa’s water supply with a new secondary disinfectant, chloramine, and will continue using chlorine as the primary disinfectant, the Oklahoma city said.

The new treatment plan, announced in June 2010, will help Tulsa meet the Environmental Protection Agency’s stricter water safety rules and provide higher standards for drinking water and longer-lasting protection, the city said in a news release.

Chloramine has been used to treat water in U.S. cities since 1917 and will help reduce the concentration of regulated disinfection byproducts in the distribution system while controlling bacterial growth in the water system, the city said.
