An analysis has revealed widespread pollution of untreated drinking water with PFAS, termed "forever chemicals," across England, especially affecting the regions served by Affinity Water and Anglian Water. Despite bans on certain harmful PFAS linked to serious health issues, thousands remain unregulated. Water UK urges for a ban and a cleanup plan funded by manufacturers, with the UK's water system grappling with PFAS levels often exceeding the Drinking Water Inspectorate's safety threshold. The problem is compounded by diverse pollution sources, including industrial sites and airports. In contrast to the UK's lenient safety standards, other countries have stricter PFAS regulations. Experts caution that current monitoring may grossly underestimate the scale of contamination.
