This article discusses how early indications from the US Environmental Protection Agency (USEPA) indicate that robust new occurrence data collected by water suppliers under the Unregulated Contaminant Monitoring Rule (UCMR) will likely justify not regulating at least five targeted chemicals. As USEPA officials explained during the
meeting, their approach for evaluating which, if
any, Contaminate Candidate List (CCL2) contaminants ultimately qualify for a
final regulatory determination requires the
agency to establish a potential health reference
level (HRL) and a known or likely level and
frequency of occurrence for each, noting that
the law requires no fewer than five to be
considered in each RD cycle. USEPA's health and occurrence findings on the
14 contaminants it is evaluating as potential regulatory determination
(RD2) candidates are briefly summarized in this article. The 14 contaminants include: 1,1,2,2-Tetrachloroethane; 1,3-Dichloropropene; 2,4- and 2,6-Dinitrotoluene (DNT); Boron; DCPA degradates; DDE; DPTC; Fonofos; Metolachlor; MTBE; Perchlorate; and, Terbacil.
