Widespread Contamination Revealed
A recent study published in the journal Environmental Science & Technology has revealed the presence of per- and polyfluoroalkyl substances (PFAS), often called “forever chemicals,” in 95% of 23 beers tested from across the United States. The research, initially announced in May 2025, highlights how environmental pollutants can enter the food supply through municipal water sources.
PFAS contamination has been documented in surface water, groundwater, and drinking water supplies throughout the U.S.and globally. While breweries typically employ water filtration and treatment systems, these are generally not designed to specifically remove PFAS compounds.
Regional Variations and Potential sources
The study indicated that beer samples from regions with known PFAS water contamination exhibited the highest concentrations of the chemicals. This suggests a direct link between local water quality and the presence of PFAS in the finished product.The findings underscore the need for increased vigilance and proactive measures within the brewing industry.
Implications for Brewers, Consumers, and Regulators
Researchers emphasize the importance of raising awareness among brewers, consumers, and regulatory bodies to mitigate PFAS exposure. Jennifer Hoponick Redmon, the research lead, stated that she hopes the findings will ”inspire water treatment strategies and policies that help reduce the likelihood of PFAS in future pours.”
As regulations surrounding PFAS in drinking water evolve, the study suggests that breweries may need to consider upgrading their water treatment facilities to ensure compliance and protect public health. This could involve investing in advanced filtration technologies capable of removing these persistent chemicals.
