140 old landfill sites in Surrey may pose a hidden danger due to untested PFAS pollution.

140 old landfill sites, originally gravel pits, in Surrey alone may pose a hidden danger to communities, according to data obtained by Watershed Investigations and the Guardian. Some sites disguised by rainwater-filled lakes have not been tested for PFAS pollution, and experts warn that thousands of polluted landfills across England could be leaking toxic chemicals into the environment, harming residents.
