Acrylamide & Epichlorohydrin (A&E)
The overuse of chemicals containing acrylamide (A) and epichlorohydrin (E) in drinking water treatment is
of concern because these
organic chemicals have been classified by the U.S. Environmental Protection Agency (EPA) as probable
human carcinogens. Due to
their small size, unlinked A&E monomers, also called residual monomers, can escape the filtration
process and end up in the finished
water for public consumption. Since there are no EPA approved methods for detection of these monomers in
finished drinking water,
treatment technique requirements were developed pertaining to water treatment chemicals containing A or
E.
