"We purchased 23 canned beer types in North Carolina stores in August 2021, with most of the beer purchases having at least 5 different cans of the same beer. Some beers are brewed in multiple locations; thus we confirmed brewing location for the purchased cans based on the brewery can code."

"They found PFAS in 95% of the beers they tested. These include perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), two forever chemicals with recently established EPA limits in drinking water."

"The most detected PFAS in beer aliquots were PFSAs–PFOS, PFBS, and PFHxS [84% (n = 63), 53% (n = 40), and 47% (n = 35), respectively]"

So if you literally drink beer like water, "While there are currently no standards for PFAS levels in beer, these drinking water standards can provide insight, as beers are intended for direct consumption similar to drinking water. We found that some of the beers exceeded the health standards."
