Forever chemicals don't break down.
They build up.

PFAS have been linked to cancer, immune suppression, thyroid disease, and developmental issues. The EPA set its first drinking water limits in 2024, but most consumers still have no easy way to know if their water is safe.

Linked to kidney and testicular cancer, liver damage, reduced vaccine response, and lower birth weight. The science is only growing clearer.
