Trace PFAS contamination widespread across Massachusetts freshwater bodies, including Connecticut and Deerfield rivers

PFAS were detected at 87% of 97 Massachusetts freshwater locations sampled from 2022 to 2024, including the Connecticut, Deerfield and Millers rivers, according to a MassPIRG Education Fund report. The chemicals, known as “forever chemicals,” can accumulate in the body and are linked to cancer, immune suppression and reproductive health problems. The group is calling for more surface-water testing and warning of potential risks to wildlife and people who use the waterways.
