The Trump administration has reached a $450 million settlement with chemical giant Chemours, after the company illegally discharged "forever chemicals" — known more commonly as PFAS — into rivers in three states for years.

According to the Associated Press, Chemours agreed to pay a civil penalty of $22.5 million for its violations, spend $90 million over the next 15 years to manage its PFAS discharges in West Virginia, North Carolina and New Jersey, install $60 million in PFAS pollution controls at its West Virginia facility, and spend $280 million to supply clean drinking water to affected communities in West Virginia and New Jersey.

PFAS are found in a range of everyday items, from nonstick cookware to fast food packaging. When ingested over time, they can lead to a range of health issues, including kidney cancer, immune system suppression, and developmental issues in children. The lawsuit against Chemours alleged that the company illegally dumped PFAS into the Ohio River, Cape Fear River and Delaware River over the course of a decade. It also marks the first ever federal settlement for a case involving a PFAS manufacturer.

This comes as the Trump administration has sought to relax limits on PFAS in drinking water. In May, the Environmental Protection Agency announced that it was planning to roll back Biden-era limits on four of six PFAS compounds, while delaying implementation of protections for the two remaining substances. At the time, EPA Administrator Lee Zeldin claimed that the previous administration had made procedural errors when it put the protections in place.
