For many, beer is more than just a drink—it’s part of social culture, celebrations, and downtime rituals. But new research suggests there may be something more unsettling hiding in your pint glass, toxic “forever chemicals.” A recent study published in ACS Environmental Science & Technology has revealed that over 95 percent of beers tested across the United States and abroad contain traces of per- and polyfluoroalkyl substances (PFAS).PFAS are a large family of manmade chemicals developed in the mid-20th century for their resistance to water, oil, heat, and stains. They’re found in non-stick cookware, water-resistant clothing, food packaging, firefighting foams, and even cosmetics. Their industrial versatility, however, comes at a steep cost: PFAS do not naturally break down, earning them the nickname “forever chemicals.”Mounting evidence links PFAS exposure to health problems, including hormonal disruption, weakened immunity, high cholesterol, liver damage, fertility challenges, and increased risks of certain cancers. The U.S. Environmental Protection Agency (EPA) recently set strict new limits on PFAS in drinking water, underscoring the urgency of the problem.How Did PFAS End Up in Beer?Beer is made primarily of water, and researchers suspected that if municipal water supplies were contaminated with PFAS, those chemicals might carry over into the brewing process. That’s exactly what this new study confirmed.The research team, led by Jennifer Hoponick Redmon, adapted an EPA-approved method normally used for testing drinking water and applied it to beer. They examined 23 beers from across the U.S. including those brewed in North Carolina, Michigan, Colorado, California, Massachusetts, Pennsylvania, Wisconsin, and Missouri as well as beers imported from Mexico and the Netherlands.The findings were striking: PFAS were present in 95 percent of samples, with contamination levels strongly correlating to the quality of local water supplies. Beers brewed near the Cape Fear River Basin in North Carolina, a region notorious for PFAS pollution, contained the highest concentrations and the widest mix of chemicals.Why This Study Say About Forever Chemicals In Beer?This is the first study to directly link municipal water contamination to PFAS levels in U.S. retail beer. While breweries often use filtration systems, these methods are not designed to capture PFAS. As a result, the contamination that begins in local rivers and reservoirs can persist all the way into the finished product.The results highlight an uncomfortable reality: PFAS contamination doesn’t just stay in the water—it spreads into food and beverages consumed daily. Beer is only the latest product to show evidence of contamination, joining an already long list that includes bottled water, fish, dairy, and vegetables.“As an occasional beer drinker myself, I wondered whether PFAS in water supplies was making its way into our pints,” said Redmon in a statement. “I hope these findings inspire water treatment strategies and policies that help reduce the likelihood of PFAS in future pours.”Her comments echo a growing consensus among environmental health experts that solving PFAS contamination requires systemic change. Since individual breweries can do little to alter the chemical composition of municipal water, solutions must come from upgrading public water systems and enforcing stricter industrial discharge regulations.What Are The Health Risks Beyond the Glass?For consumers, the immediate concern is how much PFAS exposure from beer actually contributes to long-term health risks. The EPA’s new standards set the safe threshold for certain PFAS, including perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), at near-zero levels in drinking water. While the amounts found in beer are relatively small per serving, scientists warn that cumulative exposure across multiple sources—water, food, packaging, and now beer—poses a real risk over time.The issue extends far beyond breweries. PFAS contamination has been detected in rivers, groundwater, and public water systems across the United States and around the globe. A seven-fold increase in Google searches for “PFAS” in the past five years reflects rising public concern as awareness grows.Everyday products contribute to the exposure cycle: waterproof clothing, stain-resistant upholstery, non-stick pans, and even cosmetics like waterproof mascaras can shed PFAS into the environment. Once in the ecosystem, they seep into soil, water, and eventually our bodies.For casual drinkers, a pint of beer is unlikely to be the sole driver of PFAS-related health risks. However, the study reinforces a broader message: PFAS are everywhere, and beer is another reminder of how pervasive they’ve become. Health experts emphasize that reducing exposure across all possible sources is key, since the chemicals accumulate in the body over time.As Dr. Redmon’s team points out, the solution doesn’t lie in avoiding beer altogether—it lies in addressing the root of the problem: contaminated water systems and unchecked chemical pollution.
