On Friday, three large chemical manufacturers agreed to contribute $1.19 billion to a fund to settle lawsuits brought by water utilities across the country that allege that the companies contaminated drinking water supplies with per- and polyfluorinated chemicals, or PFAs. This announcement comes as lawsuits — filed by state governments, environmental advocacy groups, water utilities and others — accuse Fayetteville, NC-based Chemours, Minnesota-based DuPont and Indiana-based Corteva of poisoning the environment and causing illness among people with long-term exposure to PFAs.
