This spot’s record
River Deben Estuary, Waldringfield is in East Suffolk, about 10 km from Felixstowe. River Deben Estuary, Waldringfield was rated Good in 2025 by the Environment Agency (England). Its previous classifications were Good in 2024 and Poor in 2023, so the rating here has moved rather than held. Across the 12 most recent samples published by the Environment Agency (England), E. coli counts ranged from 10 to 160 per 100 ml. The highest was taken on 13 July 2026. A classification is calculated from percentiles across four seasons, so no single reading decides how this water is rated.

These are the water company’s own reports of when an overflow is operating, not a measurement of the water at this spot. A discharge into a river some distance away may never reach here; a quiet list does not mean the water is clean. The swim status above comes from the bathing-water monitoring body and does not use this data.
