Study finds nonstick PFAS compounds in beer — including Michigan brews

A study by RTI International found beers brewed in places where the municipal water supply has known PFAS contamination also tend to have detectable PFAS in the beer.

The study did not name beers or brewers, but noted elevated PFAS detections in beers brewed in Kalamazoo and Kent counties.

If potentially health-harming, nonstick "forever chemicals" PFAS are in a brewery's water supply, they tend to end up in its beer, a study has found. And though the study doesn't name the beers it tested or their brewers, it found high levels of some PFAS compounds in beers from Kalamazoo and Kent counties in Michigan.

"We found if there is PFAS in the drinking water that the brewery is using that there tends to be PFAS in the beer that consumers are drinking, unless there is advanced filtration tha
