The U.S. EPA has posted a memorandum that provides information on how water systems can utilize flexibilities in the final Per- and Polyfluoroalkyl Substances (PFAS) National Primary Drinking Water Regulation (NPDWR) to use previously collected PFAS drinking water data (e.g., from UCMR 5 or state monitoring programs) to satisfy some or all of the initial monitoring requirements of the rule, as well as how this data can be applied to assess their compliance monitoring frequency under the rule. This memorandum also provides information and guidance for laboratories and water systems on implementing other aspects of the PFAS NPDWR monitoring and reporting requirements.
