Authority announced plans to begin using chloramine as a secondary
water disinfectant in Tulsa's water supply in July, 2012. The City

Why is Tulsa making this change? Switching to secondary
chloramine disinfection will help Tulsa meet the EPA's stricter
water safety rule (the
Stage 2 Disinfection Byproducts Rule), which goes into effect
in 2012 and provides higher standards for drinking water. By making
this change, the City of Tulsa will be able to provide
longer-lasting protection and water that continues to meet drinking
water standards to every part of the city.

Chloramine Quick Facts
- Chloramine, like chlorine, is a disinfectant
commonly used to treat drinking water.
- Chloramine is formed by adding trace amounts of ammonia to
chlorine in water.
- Chloramine has been used as a reliable disinfectant to treat
water in cities across the United States since 1917 --
more than 90 years.
EPA has determined that the use of chloramine will help reduce
the concentration of regulated disinfection byproducts in the
distribution system while still controlling bacterial growth in the
City's water system.
