What are forever chemicals?
Forever chemicals, scientifically known as polyfluoroalkyl substances (PFAS), are synthetic compounds that have gained notoriety for their persistence in the environment and human body. These chemicals do not break down easily, leading to their accumulation in water supplies, soil, and even food products.
Recent studies have raised concerns about their presence in everyday items, including one of America’s favorite beverages: beer.
The alarming study on beer contamination
A recent investigation conducted by the American Chemical Society’s Environmental Science & Technology has uncovered troubling findings regarding PFAS levels in beers brewed across the United States.
The research team, led by Jennifer Hoponick Redmon, modified an EPA testing tool to analyze 23 different beers, focusing on those sourced from areas known for water contamination. The results were shocking: a staggering 95% of the beers tested contained detectable levels of PFAS, particularly perfluorooctanesulfonate and perfluorooctanoic acid, both of which have established EPA limits in drinking water.
How does PFAS end up in beer?
While many breweries implement water filtration and treatment systems, these methods are often not equipped to eliminate PFAS from the brewing process. The study found a direct correlation between PFAS concentrations in municipal drinking water and the levels found in locally brewed beers.
This means that if the water used in brewing is contaminated, the final product is likely to be as well. Beers from states like North Carolina, California, and Michigan showed particularly high levels of these chemicals, raising questions about the safety of our beloved craft brews.
The implications for consumers
For the Gen-Z and young adult demographic, who often prioritize health and sustainability, these findings are particularly concerning. The idea that a casual drink could expose consumers to harmful chemicals is alarming. As awareness grows, it’s crucial for breweries to adopt more stringent water treatment practices and for consumers to demand transparency regarding the sourcing and safety of their beverages.
The research team hopes that their findings will inspire new policies and strategies to mitigate PFAS contamination in drinking water, ultimately leading to safer beer options for everyone.
