There are currently no bathing waters designated by Defra in the Surrey Heath constituency. The Environment Agency undertakes regular monitoring of the water quality in Surrey Heath constituency; the assessment and proposed actions are set out in The Thames River Basin Management Plan. Impacts from wastewater pollution are highlighted as a key pressure resulting in many waterbodies not currently achieving good ecological status.

There have been significant pollution incidents at Camberley and Chobham Sewage Treatment Works in the last few years, and these are subject to ongoing Environment Agency investigations. The Environment Agency is currently transforming its regulatory approach including developing a larger specialised workforce and delivering a step change in inspections of Thames Water's permitted sites and associated enforcement.

Water company investment of over £10 billion will improve over 2,500 storm overflows, targeted at those affecting the most sensitive sites for ecological and human health. Protected Sites Strategies will also help improve biodiversity in our coastal areas.

Where a water body has been officially designated as a bathing water the Environment Agency will carry out regular testing of the water quality at each site, as well as inspecting for the presence of a range of pollutants. Information about water quality at each site is published online via the Swimfo service.
