You’ve probably never heard of this ‘forever chemical.’ Scientists say it’s everywhere.
As cities and towns plan to remove several harmful “forever chemicals” from drinking water, scientists are starting to focus on a less-studied version of the chemicals that is showing up virtually everywhere they look. Trifluoroacetic acid, or TFA, could be one of the most widespread forever chemicals in the environment, according to a growing body of research. While there’s no consensus on its effects on human health, TFA does not break down naturally, and its similarity to per- and polyfluoroalkyl substances (PFAS) tied to cancer and other diseases is enough to warrant further study, researchers said. “It’s absolutely everywhere,” said Sarah Hale, an environmental researcher who manages ZeroPM, a project funded by the European Union. “TFA will be the next discussion in America, I can guarantee it. It will be about how should we treat it and what should we do.”
