“It is the truth,” Bilott said, assessing how accurate he feels the film is. “They did an amazing job condensing [20 years] into two hours. I was a little skeptical at first…about whether I should do something like this, but it was clear that [Mark] was doing it for the right reason: to bring the story out, to do it accurately and [he] wanted to show what really happened.”

Dr. Phil Brown talks PFAS contamination and ongoing research
News
23 Oct 2019 | Northeastern University
“It’s a big deal,” Brown says. “You put all this together and it’s the biggest chemical contamination issue in many, many years.” The important part, he says, is to regulate these chemicals as a class, rather than individually. Otherwise, each of the roughly 4,700 chemicals would need to be investigated separately, even if they had only minor molecular differences. And since the health effects are long-term problems like cancer, these studies could take decades.

EPA touts success in reducing children’s chemical exposures, fails to account for emerging contaminants
News

According to Barbara Morrissey, chairwoman of EPA’s Children’s Health Protection Advisory Committee, the reductions are “worth celebrating but only part of the picture.” To get a fuller understanding of exposure trends, the EPA’s indicators must be updated with exposure measurements for new chemicals that replaced older ones that were phased out
