A landmark moment for river swimming
The first designated bathing water area on the River Thames in London has officially opened for the bathing season, as one of 13 new monitored swimming sites across England. The Thames at Ham, in south-west London, received its designation after campaigners, including Marlene Lawrence, founder of the Teddington Bluetits wild swimming group, which has more than 2,000 members, gathered evidence demonstrating that thousands of people use the stretch year-round. Lawrence described the designation as “amazing for the river,” expressing hope that bathing water status would become a driver for keeping the Thames clean.
A diverse set of new sites across the country
The 13 new designations span coastal, estuarine and river locations across England, and are monitored from the start of the bathing season through to the end of September. Sites include Pangbourne Meadow in Berkshire (said to have inspired The Wind in the Willows) the River Fowey at Lostwithiel in Cornwall, the River Dee at Sandy Lane in Chester, the River Swale in Richmond, Yorkshire, and a sea swimming area at Little Shore in Amble, Northumberland. The full list also includes sites in Essex, Dorset, Suffolk, Kent, Merseyside, Devon, Wiltshire and Greater London.
Why designation matters for water quality
The Environment Agency is required to monitor designated bathing sites weekly throughout the summer, testing for faecal indicator organisms and publishing results publicly. The Guardian notes that campaigners have been pushing for river bathing water status for six years precisely because of the more rigorous testing it triggers, with the aim of compelling water companies, farmers and other polluters to reduce discharges. The precedent from Ilkley in West Yorkshire, where the River Wharfe became the first river designated five years ago, is held up as a key example, where Yorkshire Water is now implementing more than £85m of infrastructure improvements to improve water quality at that site.
Government frames designations as part of wider reform
Water minister Emma Hardy welcomed the new designations, pointing to improved monitoring, a boost for local tourism and greater confidence for swimmers. She framed the expansion as part of the government’s broader overhaul of the water sector, contrasting it with what she described as “years of indifference towards bathing waters.” Campaigners, including James Wallace, CEO of River Action, warn that the risk of pollution still remains despite the change in designation. Mr Wallace said the safety levels depends on factors including how polluted the River Pang has been, which feeds in further upstream, and advises swimmers to remain cautious when swimming in Pangbourne Meadow.
Thames Water said it would “continue to work closely with the Environment Agency to understand our impact at the locations and where upgrades to our assets may be needed.” The expansion of the designated bathing water network suggests that public and political pressure for cleaner rivers is translating into regulatory requirements, and investment obligations, that will only grow.
