The analysis of PFAS by EPA 1633A and ASTM D8421 is part of the U.S. EPA’s Methods Update Rule (MUR) Rule 22. The action will promulgate EPA into 40 CFR Part 136. Also part of this action, PFAS method ASTM D8421 is proposed to be codified.
The U.S. EPA officially approved Merit Laboratories to perform analytical laboratory testing for PFAS compounds as part of the fifth Unregulated Contaminant Monitoring Rule (UMCR5). As part of UCMR5, Merit Laboratories is approved for analytical methods EPA 533 and EPA 537.1. UCMR 5 includes all 29 PFAS compounds that are within the scope of EPA Methods 533 and 537.1.
The U.S. EPA has published the Fifth Unregulated Contaminant Monitoring Rule (UCMR 5). UCMR 5 requires sample collection for 30 chemical contaminants between 2023 and 2025 using analytical methods developed by EPA and consensus organizations. This action provides EPA and other interested parties with scientifically valid data on the national presence of these contaminants in drinking water. PFAS are included in the UCMR.
Years of underinvestment in Michigan’s infrastructure, including roads, bridges, dams, schools, transit, water and sewer systems, railways and energy systems, have left the state in a precarious position, according to the American Society of Civil Engineers (ASCE) 2018 Report Card for Michigan's Infrastructure and the 21st Century Infrastructure Commission.
On March 11, 2021, the EPA proposed the fifth Unregulated Contaminant Monitoring Rule (UCMR 5) UCMR 5, which will require sample collection for 30 chemical contaminants, including PFAS. The testing will occur between 2023 and 2025 using analytical methods developed by EPA and consensus organizations.
The Michigan PFAS Action Response Team (MPART) formally recommended to move forward with establishing draft maximum contaminant levels (MCLs) for PFAS compounds in drinking water. The recommendation was made by unanimous vote by MPART’s board on September 27, 2019 in Lansing. The MPART board is recommending the following health-based MCLs for seven PFAS compounds.
Moving Michigan forward on PFAS drinking water regulations, the Science Advisory Workgroup recently provided its health-based values to the Michigan PFAS Action Response Team (MPART). These PFAS health-based values will be used by the State of Michigan to develop regulatory drinking water standards.
The MDEQ has been directed by the governor to begin the process of creating PFAS drinking water standards. The MDEQ will file a Request for Rulemaking to establish maximum contaminant levels (MCLs). As part of the governor’s direction, the Michigan PFAS Action Response Team (MPART) will form a science advisory workgroup to review health-based drinking water standards to support the rulemaking process and make recommendations by July 1.
