Your river is the Dearne from Cawthorne Dyke to Lundwood STW, rated moderate

The Environment Agency rated the Dearne from Cawthorne Dyke to Lundwood STW as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by phosphate, insects and other small river life and water plants and algae. 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.

How clean is the river near S75?

The Environment Agency rated the Dearne from Cawthorne Dyke to Lundwood STW as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by phosphate, insects and other small river life and water plants and algae. 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. This is a rating of the river, not of tap water in S75, which is treated before it reaches homes.
