Imports of used PFAS into US scrutinized
News
15 Mar 2019 | Chemical & Engineering News
To meet demands for nonstick-pan coatings and fuel-cell components, Chemours depends on a fluorinated chemical called GenX. This compound helps building-block materials link together into tough, resistant plastics and industrial membranes. During the process of making these materials, GenX, an ammonium salt, ends up in water and hydrolyzes into…

The U.S. military plans to keep incinerating toxic firefighting foam, despite health risks
News
27 Jan 2019 | The Intercept
The U.S. military is moving ahead with plans to collect and destroy unused firefighting foam that contains the hazardous chemicals PFOS and PFOA. But in trying to solve one environmental problem related to these persistent chemicals, which have caused massive drinking water contamination, the Defense Department may be creating another.
