Thames Water's £350m recycling scheme hit PFOS levels 13 times UK limit in trials

Pilot tests for Thames Water's £350m Teddington recycling scheme found PFOS — a suspected carcinogen — at 13 times the UK legal limit. Carbon filters saturated in under a month, causing "rapid breakthrough of PFOS." Thames Water called compliance "operationally challenging" but is proceeding with the plan to replace abstracted Thames water with treated sewage effluent.
