Campaigners in Henley, England, are advocating for changes to the country's bathing water regulations to address pollution in the River Thames. A letter sent to Environment Secretary Emma Reynolds highlights that the current definition of 'bathers' excludes organized activities like swimming, rowing, and kayaking, which contributes to poor water quality. As a result, Henley was denied bathing water status, which is crucial for public health and local businesses. Testing has shown E coli levels in the river exceeding safe limits, with averages reaching 2,922 CFU per 100ml during the bathing season, far above the 900 CFU limit set by the Environment Agency. Local businesses, such as boat hire services, are struggling due to the river's condition. The government has acknowledged the need for a review of the definition of bathers and is exploring options to improve water quality and safety, emphasizing its commitment to cleaning up the nation’s waterways. This issue is expected to be significant in the upcoming local elections, with differing views on water company ownership and accountability.
