Study of PFAS levels in Michigan firefighters raises cautious optimism

May 19, 2026

A recent Michigan state study found that firefighters' blood levels of PFAS—toxic "forever chemicals" they encounter through protective gear and firefighting foam—are comparable to average Americans, despite their occupational exposure risks. This potentially encouraging finding coincides with Michigan's stricter state regulations on PFAS since 2020, including banning the chemicals in firefighting foam in 2022, which some researchers believe may be proving effective. However, the results arrive amid uncertainty as federal PFAS drinking water regulations are being relaxed by the Trump administration, though Michigan will maintain its own standards.

Who is affected

Michigan firefighters (specifically those surveyed between April 2021 and September 2023)
Airport firefighters (who showed higher PFAS concentrations than other firefighter groups)
Steve Heim (captain at Lincoln Park Fire Department and vice president of Michigan Professional Firefighters Union)
Older firefighters (experiencing lingering effects from historical PFAS foam use)
Young firefighters (testing positive for cancers)
The general US population (who continue to have PFAS exposures)
Michigan residents (subject to state drinking water standards)

What action is being taken

The Michigan Department of Health and Human Services is studying how firefighting foam and PFAS-treated equipment exposure affects first responders (tracking data from April 2021 through September 2023)
Michigan's state-level drinking water standards are continuing to limit PFAS compounds
Protective practices are being implemented in Michigan for firefighters

Why it matters

The findings are significant because they suggest Michigan's stricter PFAS regulations—including banning the chemicals in firefighting foam and establishing more stringent drinking water standards—may be effectively protecting firefighters from elevated exposure despite their high-risk occupation. However, the study highlights a critical gap between reduced blood-level exposure and persistently high cancer and illness rates among firefighters, indicating that current understanding of PFAS health impacts remains incomplete. The research also underscores that while occupational protections may be improving, the general population continues widespread PFAS exposure, and the relaxation of federal standards creates uncertainty about future protection levels.
