Race to find source of carcinogenic PFAS in Cumbria and Lancashire waters

Watershed uncovered a string of toxic pollution hotspots across Cumbria and Lancashire, with high levels of the banned cancer-causing “forever chemical” Pfos detected in rivers and groundwater at 25 sites.

The contamination, spread across a large area, was uncovered by Watershed Investigations and the Guardian after a freedom of information request revealed high concentrations of Pfos in Environment Agency samples taken in January 2025.
