The First Results of the Kent County PFAS Exposure Study Assessment Released

Significant levels of PFAS have been detected in the blood of Michigan residents in one state county. The results are summarized in the initial report just released by the Michigan Department of Health and Human Services (MDHHS) as part of the PFAS Exposure Study Assessment. This exposure assessment measured serum concentrations of 30 PFAS among a sample of residents in the northern part of Kent County area that previously had validated detectable PFAS levels in their private drinking water.
