The State of Michigan has lowered the drinking water health screening levels for PFAS. These new levels replace the federal advisory guidelines of a combined 70 ppt for PFOA and PFOS that the state had been using since January 2018.
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.
