On July 30, 2008, the U.S. Environmental Protection Agency (USEPA) finalized the regulatory determinations for 11 contaminants on the Second Contaminant Candidate List (CCL2). Considering the best available data, USEPA concluded that these contaminants occur infrequently at levels of public health concern in public water systems. Therefore, the agency made a determination not to regulate any of these contaminants, because setting a national primary drinking water regulation does not present a meaningful opportunity for health risk reduction on a national basis. Consequently, none of the 11 contaminants will be regulated by USEPA; however, some water systems may be vulnerable to contamination. This article summarizes the final CCL2 determinations (USEPA 2008a; 2008b). The article discusses specifics of the CCL requirements, focusing on the Safe Drinking Water Act (SDWA) and unregulated contaminant monitoring, along with specific CCL2 candidate, including boron, dacthal mono- and di-acid degradates, DDE, 1,3-dichloropropene, DNT, EPTC, Fonofos, Terbacil, and 1,1,2,2-tetrachloroethane. Includes 2 references.
