Contained in Brews: Discovery of 'Forever Chemicals' in Beers
In a groundbreaking study, researchers at RTI International have discovered that Per- and Polyfluoroalkyl Substances (PFAS) are present in a significant number of beers across the United States. The study, published in the journal Environmental Science & Technology, found PFAS in 95% of the beers tested, with the highest levels detected in beers brewed near PFAS-contaminated water sources.
The study used a modified U.S. Environmental Protection Agency (EPA) method for detecting PFAS in drinking water. It found a strong correlation between municipal water contamination and PFAS levels in beer, emphasizing the need for improved water treatment in the brewing industry.
PFAS are synthetic chemicals commonly used in consumer goods and industrial processes for their resistance to water, grease, and stains. They persist in the environment and the human body and are linked to a growing list of health concerns, including cancer, immune system disorders, and developmental issues.
The study calls for brewers to consider upgrading water filtration systems to specifically target PFAS compounds. Key improvements suggested include implementing advanced filtration technologies such as granular activated carbon (GAC) filters or ion exchange resins, upgrading municipal water sources and brewery water supplies with PFAS-specific removal steps, regularly monitoring and testing brewery water for PFAS, and raising awareness among brewers and policymakers to support regulatory and technological advancements addressing PFAS contamination risks in the brewing supply chain.
Jennifer Hoponick Redmon, the lead researcher of the study, expressed concern about PFAS in water supplies making its way into beer. She hopes the findings inspire water treatment strategies and policies to reduce the likelihood of PFAS in future beer production. The study also encourages consumers to become more aware of where their beverages come from.
Notably, PFOA and PFOS, two of the most notorious PFAS, are now under strict new EPA drinking water limits. The study is one of the first to connect PFAS contamination in drinking water directly to retail beer in the United States.
The study was supported by an internal research grant from RTI International. It urges regulators to set enforceable standards and fund infrastructure upgrades to ensure the safety of the beer consumers drink. By implementing these enhanced filtration and monitoring practices, breweries can significantly reduce PFAS presence in beer, complementing forthcoming stricter drinking water standards that may impact brewery operations.
