A recent study published by the American Chemical Society in the journal Environmental Science & Technology has uncovered the presence of per- and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals,” in a wide array of American beers.
The study, led by Jennifer Hoponick Redmon, focused on analyzing 23 beers brewed in regions known to have contaminated water systems. Results showed that 95% of the samples contained detectable levels of PFAS. Though the specific brands were not disclosed, the study highlighted that beers brewed near the Cape Fear River Basin in North Carolina exhibited the highest concentration and widest variety of PFAS compounds.
“As an occasional beer drinker myself, I wondered whether PFAS in water supplies was making its way into our pints,” said Redmon. “I hope these findings inspire water treatment strategies and policies that help reduce the likelihood of PFAS in future pours.”
PFAS are synthetic chemicals found in various industrial and consumer products. They are known for their resistance to water, oil, and heat, and have been linked to adverse health effects. Their persistence in the environment has raised growing concerns, particularly when detected in food and beverages.
