PFAS in Fish on the Huron River

Don’t eat fish from the Huron River. The State of Michigan has tested fish from multiple location on the Huron River and found high levels of PFAS. The Michigan Department of Health

and Human Services (MDHHS) issued a Do Not Eat Fish Advisory for the entire river. Because fish are mobile, the Huron River Watershed Council advises you to avoid eating fish for the river or any connected lake or creek.

PFAS accumulates in fish meat. That makes it different than previous contaminants that accumulated in fat that could be safely scraped away from the filet.

The Do Not Eat Fish Advisory for the Huron River upriver from Ypsilanti will likely continue for the foreseeable future. The advisory may be lifted sooner in areas downriver. The levels of PFAS found in the waters of Kent Lake and its fish were especially high. Lakes and river sections from Island Lake State Recreation Area to Milford will likely see the advisory remain in place longer than elsewhere.

Other recreational activities, like swimming and kayaking on the river are okay. You can read about how to protect yourself from PFAS while enjoying the river HERE.

The Huron River Watershed Council is monitoring developments regarding PFAS in the river and regularly updates the webpage at


PFAS and Recreation on the Huron River

It is Safe to Swim and Boat.

As the emerging threat of PFAS has unfolded across Michigan and on the Huron River, it’s raised concerns about recreation.

The good news is that swimming and boating on the Huron River Water Trail are still okay. For those activities, we can continue to enjoy the water as we have. PFAS isn’t a health risk when exposed to skin. It’s a health risk when ingested over time, so accidental mouthfuls of river water are no cause for concern.

The bad news is that the State of Michigan has issued a Do Not Eat Fish Advisory for the entire river.  Anglers should not eat any fish from the Huron River or the connected waterways for the foreseeable future. We expect that advisory will remain in place for several years.

The state also issued a second advisory telling people not to ingest river foam. Those of us with pets or small children should stay away from river foam when possible and avoid lingering below dams or where foam tends to occur. PFAS concentrates in foam. That said, foam is naturally occurring on the river and not all foam is PFAS foam, but it’s often impossible to know the difference by looking at it. Wash your hands and rinse off after making contact with foamy water. Rinsing with non-foamy river water is okay.

As we head into the 2019 paddling season, there are many encouraging signs. PFAS levels were much higher on the Huron River during the late summer of 2018. One of the major sources of PFAS to the river took steps to reduce its discharge of PFAS chemicals, and contamination levels on the river have dropped significantly.

There are likely several other lesser sources, and the Huron River Watershed Council is working with state and local partners to identify those sources, reduce contamination to the river, and inform paddlers on the Water Trail. Visit for updated information.

HRWC has created an informational flyer, at left, for outfitters and other Water Trail Partners who provide river-related services to the public. It is also available as a larger poster. Contact Daniel Brown at [email protected] if you need one to post at your place of business.
