What this means
PFAS (per- and polyfluoroalkyl substances) are a family of ~12,000 man-made chemicals nicknamed "forever chemicals" because they don't break down in the environment or the human body. Illinois was the first state to set enforceable drinking-water limits (2020). MPART tracks 200+ confirmed contamination sites — many from military bases, industrial sites, and firefighting foam.
What you can do
- If you're on a private well within a few miles of a known PFAS site, request a free EGLE well test.
- Boiling water does NOT remove PFAS — use a certified reverse osmosis or activated-carbon filter rated for PFAS.
- Most municipal water in MI now meets the federal MCL — check your annual Consumer Confidence Report.
- Health effects with long exposure: thyroid, liver, immune-system, and some cancers — talk to your doctor if you're concerned.
