River Bathing Sites in England: The River Wharfe Test Case

Designating Rivers for Bathing – Core Facts
In 2020 the River Wharfe at Ilkley became England’s first inland river designated as a bathing water site. Designation requires meeting criteria on bather numbers and facilities and obliges the Environment Agency to test for faecal indicator bacteria such as E.coli. Readings above 900 colony-forming units per 100 ml trigger public advisories to avoid swimming.
Background and Policy Context
The government has added six new inland river sites this summer, raising the total of regularly monitored locations to more than 460, the majority of which are coastal. Test results are posted on a public website. Water Minister Emma Hardy says the expansion “means better monitoring of our waterways, a boost for local tourism, and greater confidence for local swimmers.”
Key Actors and Their Roles
- Karen Shackleton, Ilkley Clean River Group – campaign leader urging designation to force action.
- Di Leary, local campaigner – highlights sewage overflow impacts.
- Yorkshire Water – implementing a £60 million investment programme to cut sewage discharges.
- Water UK – industry body cautioning against premature designation.
- DEFRA and the Environment Agency – set standards and conduct testing.
- Alison Biddulph, Shropshire campaigner – oversees new designations on the Severn and Teme.
Water Quality Data and Current Status
Testing of the 14 inland sites last year found only the River Stour (Suffolk) and the River Thames (Oxfordshire) within acceptable limits; the remaining 12, including the Wharfe, were rated “poor.” During rainfall, E.coli concentrations in the Wharfe can reach tens of thousands of units per 100 ml. Continuous monitoring devices (sondes) now provide hourly data downstream of the Wharfe and at newly designated sites on the Severn and Teme.
Official Responses and Policy Statements
DEFRA officials note that freshwater bathing standards are harder to meet than coastal ones because rivers receive direct inputs from sewage works and agricultural runoff, limiting natural dilution. Yorkshire Water asserts its £60 million programme will reduce overflow volumes. Water UK warns that designating sites before they meet standards “risks confusing the public, who will rightly believe it is safe to swim there.”
Criticism and Opposition
Campaigners describe the process as a “Catch-22,” arguing that encouraging swimming in polluted water creates pressure for remediation but also endangers health. Water UK’s spokesman emphasizes the risk of public misunderstanding, while activists stress the need for concrete cleanup plans.
On-the-Ground Observations
Volunteers have swum near visible overflow pipes, describing the water as “other people’s poo.” Despite “poor” ratings, they report increased focus on daily testing and anticipate gradual improvement over several years.
Conflicting Views and Information Gaps
Official statements highlight long-term investment and monitoring, yet real-time data still show high bacterial loads after rain events. No independent evaluation of the £60 million programme’s effectiveness has been released, leaving uncertainty about the timeline for achieving “good” status.
Verbatim Quotes
- “When it rains, there can be tens of thousands of E.coli units per 100ml,” — Karen Shackleton, Ilkley Clean River Group
- “We're basically swimming in other people's poo,” — Di Leary, campaigner
- “The introduction of these new bathing sites means better monitoring of our waterways, a boost for local tourism, and greater confidence for local swimmers.” — Emma Hardy, Water Minister
- “Designating an area as a bathing water before it is suitable for bathing and without a plan in place to clean it up risks confusing the public, who will rightly believe it is safe to swim there,” — Water UK spokesman
- “I think it's probably going to take five years before you see any real difference, but we've already got a lot more focus on it,” — Alison Biddulph, campaigner, Shropshire
- “It's very much a Catch 22 situation,” — Di Leary, campaigner
Outlook and Upcoming Actions
The Environment Agency will continue hourly testing at all designated sites, and Yorkshire Water’s investment programme is slated to run over the next five years. Additional inland sites will join the monitoring network this summer, providing further data to assess whether the designation strategy can translate into measurable water-quality improvements.
