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.
The list continues to grow. The Michigan PFAS Action Response Team’s (MPART) list of sites where the MDEQ has confirmed detections of PFOA and PFOS in groundwater has grown by another 16 sites. The list now includes the following sites.
The State of Michigan is developing a readiness and response plan to coordinate quick response when PFAS contamination is identified. The plan is the result of an executive directive issued by the governor on October 2. Communities across Michigan are dealing with PFAS contamination issues that require expedited response to the health threats presented by PFAS compounds.
