By State · MI
Based on EPA UCMR 5 testing of 87 public water systems with PFAS detected in Michigan.
See Michigan on the national heatmapState totals reflect systems with at least one PFAS detection in UCMR 5 (the canonical EPA dataset). The 6,151 national total includes ~123 additional systems in US territories and on tribal lands not browsable as state pages.
Most contaminated in Michigan
7 Michigan water systems tested above EPA PFAS limits. The most severe is DUNDEE, where PFOA measured 13.0 ppt — 3.3× the federal limit.
State context
Industrial context
Michigan hosts one of the most-studied PFAS contamination cases in the US — the Wolverine Worldwide tannery plume in Belmont/Plainfield Township and Rockford, where leather waterproofing using 3M's Scotchgard contaminated groundwater across thousands of properties. AFFF impacts at the former Wurtsmith AFB (Oscoda) and K.I. Sawyer AFB (Marquette) are also significant.
Regulatory stance
Michigan has been a national leader on state-level PFAS regulation. The state established drinking-water MCLs for seven PFAS compounds in 2020 (PFOA 8 ppt, PFOS 16 ppt, PFNA 6 ppt among others); the Michigan PFAS Action Response Team (MPART) is one of the most-coordinated state PFAS programs in the country.
Notable sites
Beyond Wolverine and Wurtsmith, Parchment, Belmont, Rockford, and Oscoda have all been forced to install treatment systems or distribute bottled water.

Test your water
EPA UCMR 5 tested 87 public water systems in Michigan — but at the utility entry point, not your tap. Aging pipes and indoor plumbing can change what reaches your home, and private wells aren't covered by UCMR 5 at all. To find out what's actually in your water, test it with a certified lab.
