Toxic Chemicals Spike in Thames Water Recycling Trials
27 Aug
Summary
- Forever chemical levels exceeded legal limits by 13 times during trials.
- Thames Water's recycling scheme plans to pump treated sewage into the Thames.
- The project's cost has increased from £350m to over £500m.
Recent pilot tests for Thames Water's planned water recycling scheme revealed significant spikes in toxic "forever chemicals," with levels of Pfos reaching up to 13 times the legal limit. This controversial project involves drawing tens of millions of litres of water daily from the River Thames and replacing it with treated sewage, particularly during drought conditions.
The company has publicly assured that the scheme, estimated to cost over £500m, will not harm the riverine environment. However, internal documents indicate that maintaining current water quality standards for forever chemicals and pesticides would be "operationally challenging." The high iron content in the treated water also poses a "significant detrimental impact" on the river.
Environmental groups and local representatives are opposing the project, citing irreversible environmental damage. The Environment Agency previously rejected a similar scheme in 2019 due to environmental concerns. Despite local opposition, the project's designation as a strategic infrastructure development means it could proceed without local consent.
