Mark Ruffalo’s environmental drama ‘Dark Waters’ gets DC premiere
News
20 Nov 2019 | The Hill
In his new film, Ruffalo plays lawyer Robert Bilott, who spent 20 years fighting a class action lawsuit against the DuPont chemical company, winning a more than $600 million settlement in 2017. The suit was over toxic runoff from a DuPont landfill with PFAS chemicals, which linger and contaminate water and food sources long after their initial use. There is no federal regulation of these chemicals, though the US EPA acknowledges that exposure to them can be dangerous for humans and that the chemicals can be found in food and water supplies.
