The most recent unexpected source of ‘Forever Chemicals’ has been traced back to a Memorial Day barbecue staple. The American Chemical Society discovered that beer brewed in certain regions of the United States contains potentially harmful chemicals known as PFAS (per- and polyfluoroalkyl substances). These synthetic compounds have been associated with health issues like cancer. The study revealed that regions with contaminated tap water had the highest levels of forever chemicals in their locally brewed beers.

Research lead Jennifer Hoponick Redmon expressed the significance of these findings, stating, “I hope these findings inspire water treatment strategies and policies that help reduce the likelihood of PFAS in future pours.” The presence of these chemicals in beer raises concerns about the contamination of drinking water sources and the potential risks consumers face. The study, published in the journal Environmental Science & Technology, sheds light on the widespread impact of forever chemicals on everyday products like beer.
Beer, made up of around 90% water along with ingredients like malt, hops, and yeast, carries the risk of being contaminated by forever chemicals present in the brewing water. Despite breweries typically having filtration systems in place, these may not effectively remove such contaminants, leading to potentially harmful levels of PFAS in the final product. The study tested 23 different beers, finding that 95% of them contained forever chemicals, highlighting the pervasive nature of this issue in the brewing industry.
While the study did not name specific beer brands, it identified regions like Cape Fear River Basin in North Carolina and St. Louis County, Missouri, as having particularly high levels of PFAS in their local brews. This correlation between contaminated tap water and PFAS in beer production underscores the need for increased awareness and regulatory action to protect consumers. The Environmental Protection Agency’s recent revisions to regulations on PFOS and PFOA in tap water signal a growing recognition of the dangers posed by forever chemicals.
As the spotlight turns to the potential health risks associated with forever chemicals in beer, researchers and regulators are urging for improved water treatment processes and stricter policies to safeguard public health. The study’s findings serve as a wake-up call for the brewing industry to address the presence of PFAS in their production methods and push for more stringent quality control measures. By raising awareness and advocating for preventive measures, the hope is to minimise consumers’ exposure to harmful forever chemicals in their favourite beverages.
The discovery of forever chemicals in beer highlights the complex challenges posed by these persistent substances in our daily lives. With growing concerns over the prevalence of PFAS in various products, from drinking water to alcoholic beverages, there is a pressing need for collaborative efforts to mitigate the risks and protect public health. As research continues to uncover the extent of contamination in everyday items, it is essential for consumers to stay informed and advocate for safer practices within industries like brewing to ensure the products we enjoy are free from harmful chemicals.
