## Overview

PFAS (per- and polyfluoroalkyl substances) are persistent chemicals used in firefighting foam, industrial processes, and consumer products. Litigation includes municipal water utilities, property owners, and individuals alleging cancers and chronic disease from drinking-water contamination.

### Exposure sources and science

AFFF firefighting foam near airports and military bases, industrial discharges, and landfill leachate have contaminated aquifers. Plaintiffs rely on toxicology literature linking certain PFAS to kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, and other conditions—defendants challenge dose-response and alternative causes.

MDL proceedings in South Carolina have produced landmark municipal settlements while individual personal-injury claims continue.

### Layers of litigation

Water-provider settlements address remediation costs; personal-injury tracks focus on individual medical proof and geographic proximity to contaminated wells.

Some states have adopted stricter drinking-water standards, influencing remediation timelines and notice obligations.
