The Nickel Report

What They Are:  PFASs (per- and polyfluoroalkyl substances) comprise a group of highly fluorinated manmade compounds that are showing up in drinking water supplies around the country. They are resistant to heat, water and oil, as well as to chemical breakdown. Because of these properties, PFASs have been used for decades as surface protection in a wide range of consumer products including carpets, clothing, cookware and food industry paper products such as pizza boxes and sandwich wrappers. PFASs are also present in foam used for fighting fires involving flammable or combustible liquids, such as oil and gasoline. Additionally, mist suppressants for metal plating operations may contain PFASs.
