Water utilities should be prepared for media and customer inquiries stemming from a U.S. Environmental Protection Agency (EPA) press release issued today entitled, “EPA issues final action for perchlorate in drinking water,” which states, “the agency has determined that perchlorate does not meet the criteria for regulation as a drinking water contaminant under the Safe Drinking Water Act. Therefore, the Agency is withdrawing the 2011 regulatory determination and is making a final determination to not issue a national regulation for perchlorate at this time.” The media, including Bloomberg and others, are reporting on EPA’s decision. AWWA issued a brief public statement today that supports EPA’s decision, noting that it’s consistent with the Association’s own analyses on perchlorate over many years. The action taken by the Agency is, according to EPA, “ consistent with Congress’ direction to prioritize SDWA decisions based on the best available public health information .” EPA determined that “the occurrence and health effects information used as the basis for the 2011 determination no longer constitute ‘best available information,’ are no longer accurate, and no longer support the Agency’s prioritization of perchlorate for regulation. Since perchlorate is not found in drinking water “with a frequency and at levels of public health concern to support a meaningful opportunity for health risk reduction through a national perchlorate drinking water regulation.” “State and local water systems are effectively and efficiently managing levels of perchlorate. Our state partners deserve credit for their leadership on protecting public health in their communities, not unnecessary federal intervention,” EPA Administrator Andrew Wheeler said in making the announcement. The main factors include contributing to reduced occurrence include: Drinking water regulations for perchlorate in Massachusetts and California. Federal and state remediation activities at perchlorate contaminated sites, particularly the ongoing remediation efforts in the state of Nevada to address perchlorate contamination in groundwater adjacent to the lower Colorado River upstream of Lake Mead. Improved procedures for storage and handling of hypochlorite solutions used as drinking water disinfectants .
