5. How does epichlorohydrin get into my drinking water?

During manufacturing of the epichlorohydrin-based polymeric coagulant aids, a small amount of epichlorohydrin may remain in the coagulant aids as an impurity. When these coagulant aids are used in water treatment, there is a potential for residual epichlorohydrin to be introduced in water. Finished water may also contain epichlorohydrin because of raw water contamination from other uses of epichlorohydrin and because of leaching from epichlorohydrin based components and materials used in drinking water treatment, storage and distribution.

A federal law called the Emergency Planning and Community Right to Know Act (EPCRA) requires facilities in certain industries, which manufacture, process, or use significant amounts of toxic chemicals, to report annually on their releases of these chemicals. For more information on the uses and releases of chemicals in your state, contact the Community Right-to-Know Hotline: (800) 424-9346.
