Per- and Polyfluoroalkyl Substances (PFAS) have become a major health and environmental concern in the U.S. Legal actions against PFAS manufacturers emerged after research linked these chemicals to serious risks. Originally valued for their industrial durability, PFAS were later discovered to persist in the environment and pose significant harm.

While initial lawsuits targeted industries and communities directly affected, the growing awareness of widespread water contamination led to broader legal efforts. Today, mass tort cases bring together individuals impacted by PFAS exposure, fighting for justice and rightful compensation.
