EPA Publishes Third Round of Regulatory Determinations for Drinking Water Contaminants

Cadmus Provided Extensive Technical and Programmatic Support

WALTHAM, Mass., January 8, 2016—The U.S. Environmental Protection Agency (EPA) has published regulatory determinations regarding four of the 116 contaminants listed on the Third Contaminant Candidate List (CCL). EPA has determined not to issue national primary drinking water regulations for dimethoate, 1,3-dinitrobenzene, terbufos, and terbufos sulfone.

EPA also announced that further study is necessary for strontium, a fifth contaminant it had considered, to determine if there is a meaningful opportunity for health risk reduction from a national drinking water regulation on strontium.

The Safe Drinking Water Act requires EPA to prepare a new CCL every five years, and to make a regulatory determination every five years on at least five contaminants chosen from the list. Cadmus has supported these efforts since the first round of the CCL and regulatory determinations, published in 2002. Through its ongoing support for the CCL and the regulatory determinations program, Cadmus helps EPA identify and prioritize emerging drinking water contaminants and evaluate high-priority contaminants against statutory criteria for federal regulation.

Cadmus has provided extensive scientific, engineering, policy and programmatic support to EPA’s Office of Ground Water and Drinking Water for more than 20 years. Learn more about Cadmus’ support for the Safe Drinking Water Act and other federal drinking water protections.
