More Extensive Sampling at The Lido, Knaresborough!

A nationwide project is starting up at UK freshwater Bathing Water sites, including The Lido at Knaresborough.

A collaboration between Watershed Investigations WATERSHED Investigations - in-depth coverage of the water crisis , the University of York, and Surfers Against Sewage aims to establish a more in depth understanding of the water quality at UK Bathing Waters than is currently happening through the Environment Agency's weekly sampling.

The project envisage taking two samples a day from the same location that EA uses, for a week in July.
The water samples will be laboratory-analyzed for E.coli (with eDNA (Microbial Source Tracking) to differentiate between human and animal based pollution), nutrient chemicals and pharmaceuticals including forever chemicals.

Nidd Action Group has joined the project and will be doing the sampling at The Lido according to a University of York protocol (similar I suspect to that NAG used earlier this year in the pilot survey we did on Bilton Beck)

As this is just at one location, NAG won't need a large numbers of samplers as in last year's river-length samplings. However if you'd like to be involved, or kept in detailed touch, contact NAG at info@niddactiongroup.org

Our Aims

A Cleaner Nidd, Fit for Life

Make rivers safe for all.
Rivers should be safe for everyone - from invertebrates (which are a vital part of the food chain) to fish, birds, animals and people.
Stop sewage pollution.
End the illegal release of untreated sewage into the River Nidd
Raise the bar.
Improve standards, so legally discharged waste doesn't harm the River Nidd

'A summary of NAG's 2023' Read the Stray Ferret article here


  • A bid has been submitted for Designated Bathing Water Status for The Lido. Read more here and here


  • Yorkshire Water have proposed investment in sewage treatment and the sewerage network in their business plan for 2025-2030 Read more here and here.

  • A document from January 2024 summarises very briefly what NAG did in 2023, with links to two maps showing the results of our sampling in terms of human health and chemical pollution at the 45 locations sampled. View it here. The document also identifies what we don't yet know and therefore what we need to do to fill in those gaps in our knowledge during 2024 and beyond, building on what we have discovered during our 2023 surveys Detailed specific plans based on this analysis will develop over the next few months

An afternoon (and evening if you want some hands on outdoors stuff) all about the Wharfe. Displays, talks and discussion details attached

The Wharfe, the Nidd's bigger neighbour, was the inspiration for NAG's citizen science work and getting Bathing Water Status.

They are a great bunch of people and we still have a lot to learn from them. I am going! More details here
