Your river is the Langney Sewer at Eastbourne, rated poor

The Environment Agency rated the Langney Sewer at Eastbourne as poor for ecological health in its 2025 assessment, meaning the river is badly affected, with much of the expected wildlife missing. It is held back by dissolved oxygen, water plants and algae and phosphate. It fails the chemical test, as every river, estuary and stretch of coast in England does, because of long-lasting pollutants such as mercury, PFOS (a forever chemical) and old flame retardants.
