Researchers point to contaminated water after ‘forever chemicals’ found in all but one of 23 sampled beers

All but one of 23 beers sampled for toxic Pfas “forever chemicals” contained the compounds, new research finds, raising safety questions about one of the world’s most popular beverages.

The researchers checked craft beer from multiple states, major domestic brands, and several international labels.

When possible, they compared the measurements to Pfas levels in the county water supply where each was bottled, revealing a “strong correlation” that suggests contaminated water is driving most of the problem. The levels were often above some drinking water limits for Pfas.
