Another suspected pollution incident on the River Wey has raised fresh concerns over a recurring problem in Haslemere.

A social media post reported that the river was clear at 10.45am on August 24 but appeared polluted 35 minutes later near a culvert on Sturt Road, opposite the Leisure Centre exit.

The Environment Agency said the post had been passed to its Environmental Management team for assessment, but confirmed it had not received an official report about the location.

An Environment Agency spokesperson said: “Potential pollution sightings should be shared with the Environment Agency via our 24-hour hotline on 0800 80 70 60 or via our website as soon as possible, including detailed information, the precise location on the river, and supporting photos or videos.

“This allows our teams to assess and investigate the pollution quickly, as speed is crucial in cases like this.”

The latest report comes 18 months after a major contamination incident in March 2025 which killed at least 70 fish and caused foaming on the River Wey around Shottermill and Camelsdale.

Haslemere Town Councillor and water ranger Claire Matthes says the latest incident highlights that the problem has not gone away.

She recently met with the River Wey Trust and Thames Water engineers to discuss the recurring issue, with the Trust putting together a project proposal to seek funding to investigate it.

“Haslemere needs specific help to find out what’s happening. We all know there’s a problem and we are taking it seriously,” she said.

Alistair Young, from the River Wey Trust, said: “We are working to source funding to increase the frequency of our testing, establishing a programme of weekly volunteer monitoring at Camelsdale and along the Wey tributaries in and around Haslemere. With this we will be able to have a better, continuous picture of river health.

“These regular tests will help to spot water quality changes, and with this information, we can work directly alongside the Environment Agency and the water companies to pinpoint pollution sources and focus real lasting improvements.”
