Water Associations Support Positive Regulatory Determination for PFAS by ACWA Staff Jun 3, 2020 Water News ACWA is among nine leading water associations urging the U.S. Environmental Protection Agency to use “sound science and robust analyses” as it evaluates drinking water standards for two per- and polyfluorinated substances (PFAS). In addition to ACWA, the June 3 letter addressed to EPA Administrator Andrew Wheeler was signed by representatives from the Association of Metropolitan Water Agencies, American Water Works Association, Ground Water Protection Council, Irrigation Association, National Association of Water Companies, National Ground Water Association, National Rural Water Association and National Water Resources Association. It urges the EPA to employ a holistic regulatory approach that protects source water from PFAS contamination, addresses public health concerns and ensures public confidence. Signing on to the letter is among a number of ongoing engagement efforts by ACWA in support of a science-based approach to developing regulations on PFAS. The EPA on Feb. 20 announced its proposal to regulate PFOS and PFOA, two PFAS compounds, and requested comment on regulatory approaches for other PFAS. In the absence of a federal standard, several states have moved forward with setting their own regulations for various PFAS, including California. “We ask that EPA move expeditiously to prepare the requisite analyses critical to proposing sound drinking water standards,” the associations jointly stated. “The implications of regulating these substances will be far-reaching.” A copy of the letter can be found on ACWA’s website.
