About PFAS "Forever Chemicals"

PFAS are a group of synthetic chemicals that have been used since the 1940s in products like non-stick cookware, water-repellent clothing, and firefighting foam. They're called "forever chemicals" because they don't break down naturally in the environment or in the human body.

Research has linked PFAS exposure to various health issues including cancer, thyroid problems, immune system effects, and developmental issues in children.

The EPA is developing new regulations to limit PFAS in drinking water. Many water systems are proactively installing treatment systems to remove PFAS even before regulations take effect.
