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 recently finalized a rule that will provide the largest-ever dataset of per- and polyfluoroalkyl substances (PFAS) manufactured and used in the United States. The finalized reporting rule under the Toxic Substances Control Act (TSCA) is a statutory requirement with the National Defense Authorization Act (NDAA - FY2020).
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.
There are many locations in the state of Michigan where PFAS pollution has become widespread and where warnings been put in place such as; ’Do Not Eat’ fish advisories, and ‘No Swim Zones’. For example, residents living near the Wurtsmith Air Force Base, have health advisories in place warning people not to consume fish, deer and other wildlife in several areas, and avoid toxic surface water foam. The federal government, however, has yet to provide a universal, nationwide standard for PFAS.
