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.

PFAS chemicals raise questions about water safety
News
15 Nov 2019 | Seacoast Online
“Unfortunately, we have only begun to explore the extent of the PFAS problem,” said Patrick MacRoy, the deputy director of the Environmental Health Strategy Center. “Relatively few water supplies in Maine have been tested, and the state has yet to test most of the agricultural lands that were contaminated by PFAS-laden sludge. In addition to polluting the groundwater, this contamination may also be contaminating crops and animal feed, allowing PFAS to enter our food supply. The state must take aggressive action to uncover where we are being exposed to PFAS.
