Study finds nonstick PFAS compounds in beer — including Michigan brews

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 that's happening like reverse osmosis or activated carbon − which is not happening in a lot of cases at this time," said Jennifer Hoponick Redmon, the study's lead author. Redmon is senior director of the environmental health and water quality program at RTI International , an independent, non
