River Thames Water Quality Classified as Poor Ahead of Oxford-Cambridge Boat Race
Concerns over River Thames water quality have surfaced as clean water advocates classify the stretch hosting the upcoming Oxford Cambridge Boat Race as poor due to E. coli contamination from sewage pollution. Tests conducted along the four-mile course, set to be navigated by university rowing teams, revealed E. coli levels exceeding the threshold for poor bathing water status by threefold.
Elevated E. Coli Levels Raise Health Concerns
According to Environment Agency guidelines, a “poor” classification advises against bathing due to potential health risks. The recent assessments highlight significant contamination, casting a shadow over the historic Boat Race. Water samples taken along the race route showed alarming levels of E. coli, a clear indicator of fecal contamination and potential sewage ingress.
Historical Context and Recurring Issues
The Boat Race, a celebrated tradition dating back to 1829, faced similar sewage pollution anxieties in the previous year. Following their victory, the Oxford team disclosed that several members suffered illnesses leading up to the event, raising questions about the river’s impact on athlete health. This year’s findings amplify these concerns, indicating a persistent problem with water quality in the River Thames.
Impact on Other River Events
The poor water quality has also affected other aquatic sporting events. A long-standing Thames swimming competition, held annually for over a century, was recently canceled due to fears of illness stemming from river contamination. This cancellation underscores the broader implications of Thames pollution on recreational activities and public health.
Calls for Action to Improve Water Quality
Sir Steve Redgrave, the esteemed Olympic gold medalist, has voiced strong concerns, emphasizing the need to protect rowers from polluted water. He stated, “It’s a real worry that in 2025, unsafe water quality in the Thames is still a concern. Rowers, river users, and the public deserve better.” His statement adds weight to the growing calls for improved river water quality management.

Dry Weather Sewage Discharges Spark Scrutiny
Testing conducted over several weeks along the Boat Race route revealed that a substantial percentage of samples surpassed safe limits for water entry, registering nearly three times the threshold for “poor” bathing waters. Adding to the concern, these findings emerged during a particularly dry weather period. Regulations stipulate that raw sewage discharges from storm overflows should only occur during exceptional weather conditions, such as heavy rainfall. Consequently, sewage spills during dry spells could be unlawful, prompting further investigation into the source and legality of these discharges.
Campaigners Advocate for Public Health Benchmark
While the Boat Race route lacks official bathing water status, campaigners from River Action, who spearheaded the testing, employed the bathing water threshold as a reference point to illustrate the potential risk to public health. This approach underscores the severity of the E. coli pollution and its potential impact on individuals using the river.
Sewage Outflow Monitor Out of Service
River Action also reported that a monitor situated on a sewage outflow at Kew, located upstream from the Boat Race finish line, became non-operational in January and remained offline throughout the entire testing period. The absence of monitoring data from this key location raises further questions about transparency and the comprehensive assessment of sewage pollution levels.
Treated Sewage Discharge: An Overlooked Factor
In addition to raw sewage, treated sewage from Thames Water treatment facilities is routinely discharged into the river. River Action posits that pollution from these treatment plants, which currently face no legal restrictions regarding E. coli limits, represents a significant and often underestimated factor contributing to the unsafe water quality.
Coxswains’ Toss Tradition Under Question
Erica Popplewell, Head of Communities at River Action, suggested that the victorious Boat Race crew should reconsider the customary tradition of throwing their coxswain into the river after the race, given the concerning pollution levels. This cautionary advice highlights the immediate, tangible risks associated with river contact.
Demand for Water Industry Reform
Ms. Popplewell further asserted the need for systemic reform within the water industry and its regulatory bodies. She emphasized public demand for immediate action from Thames Water and regulators to upgrade sewage treatment infrastructure. She stated, “The public demands Thames Water and regulators act now to improve sewage treatment infrastructure.”
Calls for Public Benefit Operation
River Action advocates for Thames Water to be placed under government control and managed for public benefit, rather than private profit. This proposal reflects growing dissatisfaction with the current operational model and its perceived failures in addressing sewage pollution.
Financial Challenges and Ratepayer Burden
Recent attempts to place the struggling water company into special administration were unsuccessful. Thames Water proceeded with a substantial bailout loan, bearing a high interest rate. Despite recent bill increases, the company seeks further rate hikes, raising concerns about the financial burden on consumers while the issue of river pollution persists.
British Rowing Issues Guidance
Rachel Dulai, Sustainability Lead at British Rowing, stated that their organization provides guidance on precautions rowers can take when water quality is poor to safeguard their health. This guidance has been disseminated to athletes participating in the Boat Race and associated clubs. British Rowing emphasizes ongoing efforts with clean water partners to advocate for cleaner water and conduct regular testing to keep the rowing community informed.
Thames Water Responds to Concerns
A Thames Water spokesperson acknowledged the dynamic nature of rivers, noting that sample results can fluctuate significantly in short timeframes. They clarified that the Boat Race route is not designated as a bathing water area, and therefore, routine disinfection of final effluent is not funded. The spokesperson also highlighted the Thames Tideway Tunnel project, which has significantly reduced sewage discharge into the tidal Thames. Thames Water maintains that they are committed to investing record amounts to upgrade aging infrastructure and improve river health.
