About this verdict
The classification, lab samples and pollution warnings above are the Environment Agency's own published data for this designated site; River Truth adds live storm-overflow context from the National Storm Overflow Hub. Sample results reflect water quality at the time of testing and this page is not formal bathing advice — heed any on-site signage.
