Michigan PFAS Sites and Areas of Interest

This is the official list of PFAS Sites and Areas of Interest in Michigan. Areas of Interest (AOI) are areas being investigated due to the potential for PFAS contamination to be affecting residential drinking water wells for which a source has not been determined. AOIs are created based on data showing the potential for human exposure, which may also generate significant public interest. This data is updated as new PFAS sites and AOIs are encountered.
