The title was scary until I saw:

> Researchers tested 23 different beers from across the U.S. and found that 95% contained PFAS

23 beers across the 10,000+ breweries in the US? Ok, lets find out more

> By modifying a U.S. Environmental Protection Agency (EPA) testing method for analyzing levels of PFAS in drinking water, Hoponick Redmon and colleagues tested 23 beers. The test subjects were produced by U.S. brewers in areas with documented water system contamination, plus popular domestic and international beers from larger companies with unknown water sources.

So, 95% of the beer they tested from a few known water-contaminated locales had PFAS, but I don't think 95% of the beer produced in the US is brewed in such places. Yeah, it makes sense that garbage water in = garbage beer out (this tracks with non-PFSA issues too)
