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.

DuPont has spread its pollution around the world. Now it wants to filter your contaminated drinking water
News
11 Dec 2018 | The Intercept
DuPont opened a factory in Saudi Arabia that will produce reverse osmosis water filters. The filters use ultra-thin membranes to remove water impurities, including PFAS — chemicals made and used by DuPont that have caused widespread water contamination around the world... “DuPont has learned the art of making money coming and going,” said Telsey. “They profited off the environmental contamination and now can profit on cleaning it up. It’s quite a feat.”...
