Forever Chemicals
Maybe you are relocating to Michigan, maybe you have lived here for years and a neighbor's worry got you reading. Either way, the figures below come from testing at regulated public systems near this address, and they belong to a state that moved early. Michigan's Department of Environment, Great Lakes, and Energy, EGLE, set its own enforceable PFAS drinking-water standards before the federal rule arrived, and its Drinking Water and Environmental Health Division runs the program day to day. None of the numbers here is a verdict on a single home. They are what the public records show, organized so the picture is legible when you are evaluating an address rather than left to imagine the worst.
EPA's UCMR 5 program (2021–2024) tested 58 public water systems in Michigan for 29 PFAS compounds; 3 reported at least one detection and none exceeded the 2024 federal limit of 4 ppt for PFOA/PFOS (a 5% detection rate). Detections vary by water system — check the utility serving a specific Michigan address.
If you are trying to understand water in Michigan, the agency to know is the Department of Environment, Great Lakes, and Energy, known as EGLE, which took on its current name after a 2019 rebrand from the old DEQ. Through its Drinking Water and Environmental Health Division, EGLE is among the states that set their own enforceable PFAS drinking-water limits ahead of the April 2024 federal rule, adopting a set of state standards covering several PFAS compounds. The reassuring part is plain: a named state agency, not just a federal one, is responsible for the standards Michigan's regulated systems answer to. Yes, the acronym changed; the accountability did not.
Numbers below come straight from EPA UCMR 5 monitoring (2021–2024). Every public water system in Michiganserving more than 3,300 people had to test for 29 different PFAS — here's what they reported.

Red triangles are military installations the Department of Defense has flagged for PFAS from firefighting foam. Orange dots are industrial facilities that reported PFAS to the EPA Toxics Release Inventory. If your future home sits near a cluster, that's a conversation worth having with the seller or landlord.
These are the Michiganutilities where EPA testing found PFAS the most often or at the highest levels. Being on this list doesn't automatically mean today's tap water is unsafe — some systems have added treatment since these samples were taken — but it means a conversation with the utility is worth having before you move in.
| Water system | Detections | Max value (ng/L) | vs 2024 MCL |
|---|---|---|---|
| MIDLAND, CITY OF | 1 | 0.01 | Below MCL |
| BATTLE CREEK - VERONA SYSTEM | 1 | 0 | Below MCL |
| ANN ARBOR | 1 | 0 | Below MCL |
PFAS isn't one chemical — it's a family of thousands. Here are the specific compounds EPA picked up most often across Michigan water systems. PFOA and PFOS are the two with the strictest federal limits (4 parts per trillion).
For decades the military trained with AFFF firefighting foam loaded with PFAS. It soaked into soil and groundwater and, in many places, traveled miles. If you're house-hunting near any of these Michigan installations, the address report will tell you exactly how close.

Looking at a specific Michigancity? Each page below pulls the same federal data narrowed to that water system — useful whether you're relocating, buying, organizing your neighborhood around getting cleaner water, or just trying to find out what's in the tap and what's around you.
Start with how to read this. Under the federal UCMR5 program, public systems serving more than 3,300 people tested for 29 PFAS compounds between 2021 and 2024, which means the figures above describe those systems in those years, not your tap this morning. If your home is on a private well, or a small rural system that fell below the testing threshold, the numbers here do not reach you, and EGLE's well-testing guidance is where you would actually start. And a detection recorded in 2022 is a moment in time, not a permanent verdict. Michigan rebranded its environmental agency mid-decade, which is the kind of thing that keeps acronyms interesting, but the underlying record is what counts.
There is a specific reason military installations show up in any water conversation. Firefighting foam called AFFF was used heavily in training for decades, and it is built on the same PFAS chemistry that lingers in soil and groundwater long after the foam is gone. That is why the installations listed above are worth attention when you take in the regional picture. For veterans and military families in Michigan, this is personal, and the aim here is to show you the records honestly, not to turn anyone's service into a cautionary tale.
Yes. EPA UCMR 5 monitoring (2021–2024) tested 58 public water systems in Michigan; 3 had at least one PFAS detection. Detections vary by water system — check your specific serving utility.
Yes. Michigan is among the states that set their own enforceable PFAS drinking-water limits ahead of the April 2024 federal rule, adopting state standards covering several PFAS compounds. The Department of Environment, Great Lakes, and Energy (EGLE) administers them, alongside the federal limits of 4 ppt for PFOA and PFOS.
Michigan's Department of Environment, Great Lakes, and Energy (EGLE) regulates PFAS in public drinking water through its Drinking Water and Environmental Health Division, which administers the state's own enforceable standards. Michigan tends to be counted among the states that acted on PFAS ahead of the federal rule.
EGLE is the Michigan Department of Environment, Great Lakes, and Energy, the state environmental agency renamed in 2019 from the former DEQ. It oversees drinking water, contaminated-site cleanup, and environmental permitting across Michigan.
Use VetMyAddress to see the PFAS detections reported for the public water system serving any Michigan address, alongside nearby military bases and industrial PFAS sources. The data comes from EPA UCMR 5, EPA TRI, and the DoD PFAS installation report.
In April 2024 the EPA set the first enforceable federal limits for PFAS in drinking water: 4 parts per trillion for PFOA and PFOS, and 10 ppt each for PFHxS, PFNA, and HFPO-DA (GenX), plus a Hazard Index for certain mixtures. Public water systems must complete initial monitoring by 2027 and come into compliance after that.
No. The federal limits apply to public water systems. Private well owners are responsible for their own testing and treatment, which is especially worth doing near a known PFAS source like a military base or industrial site.
State numbers tell you the pattern. An address report tells you what's actually in the water at yourkitchen sink — the matched utility, the PFAS detections on file, and every military or industrial source nearby. Whether it's for your family, your neighbors, or peace of mind.
