New sensors provide Shrewsbury wild swimmers with real-time water quality data
Wild swimmers in Shrewsbury can now make better-informed decisions about river safety through an expanded regional pilot project, which monitors river water quality on a daily basis.
The Environment Agency has installed high-tech autonomous sensors in the River Severn at Shrewsbury, to remotely provide daily readings on bacteria levels including E. coli.
Last week, the Shrewsbury data was launched on the Shropshire Wild Bathing app, allowing river users to check current water quality conditions and decide when it's safe to swim. The water quality data is automatically uploaded every hour onto the app developed by the River Severn Partnership.
The daily readings complement existing weekly statutory monitoring throughout the bathing water season from 15 May to 30 September. The Environment Agency takes over 7,000 samples at 451 designated bathing waters across England during this period.
Martin Quine, Environment Agency Place Manager for Shropshire, said: “This project is important because it enables users of the bathing site to make informed decisions on when they access the river. It’s also important for us to get the data to understand where pollution is coming from, so we can target our work to those places where it will have maximum benefit.”
The project expanded to Shrewsbury after the success of the River Severn Partnership’s research and development initiative in Ludlow earlier this year, which has also resumed this month.
The research project has accelerated the Environment Agency’s understanding of how bacteria in rivers behave throughout the year, and particularly during the bathing water season. The data helps us better understand and identify sources of pollution, and will inform possible future methods of managing bathing waters.
Funding has also been secured to extend the research project to Ironbridge in 2026, demonstrating the government's commitment to exploring innovative water quality monitoring methods to improve water quality monitoring and public safety.
Wild swimmers can download the Shropshire Wild Bathing app on Google Play store or Apple App Store to access up-to-date water quality information for Shrewsbury and Ludlow.
This initiative supports the government's Plan for Change commitment to building a cleaner, healthier environment for communities across the UK.
