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.”...
