Michigan’s PFAS Discovery and Response
Michigan’s PFAS crisis emerged rapidly following a 2017 investigative media report on contamination near military bases and industrial sites. The state activated a multi-agency PFAS response team and initiated the broadest state PFAS monitoring program in the country, testing water at hundreds of locations across the state.
The monitoring revealed extensive contamination at 11,000+ sites including military installations, airports, industrial facilities, and municipal water systems. Several major contaminated sites — including areas near Kalamazoo, Grand Rapids, and Rockford — required immediate intervention including provision of bottled water and installation of treatment systems.
Regulatory Program Development
Michigan developed Part 201 environmental cleanup criteria for PFAS in soil and groundwater — among the nation’s most comprehensive and scientifically rigorous PFAS cleanup standards. The criteria use risk-based approaches that consider exposure pathways, land use, and sensitive receptor protection.
The Michigan PFAS Action Team (MPART) coordinates response across 20 state agencies, providing an organizational model for integrated PFAS management that other states have studied. Michigan’s approach emphasizes both immediate community protection (alternative water supply, point-of-use filters) and long-term remediation accountability.
Community Engagement Innovations
Michigan’s PFAS program has pioneered community engagement approaches including direct community meetings in affected areas, dedicated PFAS hotlines, and clear information materials in multiple languages. The state provides free blood testing for community members near confirmed contamination sites — a service that builds trust and provides individual health information.
Michigan’s experience demonstrates that transparent, well-resourced, multi-agency PFAS response programs can effectively protect communities while building the regulatory infrastructure for long-term contamination management. The state continues to expand its monitoring network and update cleanup standards as new health evidence emerges.
