New study says more than 57,400 US sites have PFAS contamination

Scientists have identified more than 57,400 sites in the United States that can be presumed to be contaminated with toxins linked to cancer and other health problems, according to a study published on Wednesday.

The sites identified by the analysis include 49,145 industrial facilities, 4,255 wastewater treatment plants, 3,493 military sites, and 519 airports. A map of the sites is publicly available on a PFAS Project Lab website.

PFAS, an acronym for per- and polyfluoroalkyl substances, are a class of thousands of chemicals commonly used to make such things as food packaging, cookware, fabrics, paints, and fire-fighting foams. Exposures to some types of PFAS have been linked to a range of adverse human health issues, including certain types of cancer, birth defects, and reproductive issues.
