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.
As the nation’s PFAS contamination problem continues to grow, a report recently released by the Environmental Working Group states that PFAS manufacturers have known about the risks associated with these chemicals for more than 60 years. The report documents studies and internal memos with a timeline that begins in 1950. PFAS manufacturers 3M and DuPont are the focus of the report.
In May, we shared with you information about a national PFAS contamination site tracker being maintained by Northeastern University’s Social Science Environmental Health Institute (SSEHRI). At the time, there were 17 sites in Michigan on the SSEHRI PFAS Contamination Site Tracker list. In just four months, the number has increased to now include 28 Michigan sites with PFAS contamination.
