Under the Biden Administration, the U.S. Environmental Protection Agency (EPA) has officially designated two of the most common PFAS as hazardous substances under the country's Superfund program. The new rule, which targets contamination from per- and poly-fluoroalkyl substances, will require companies to report leaks and help pay to clean up existing contaminations. Where PFAS-related litigation already floods the country's courthouses, a significant uptick in additional claims is imminent. 

This follows the previous week's EPA announcement of its first-ever drinking water standards to guard against PFAS pollution.
