Your river is the Derwent from Bottle Brook to Trent, rated moderate
The Environment Agency rated the Derwent from Bottle Brook to Trent as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by water plants and algae, phosphate and specific pollutants. 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 DE72?
The Environment Agency rated the Derwent from Bottle Brook to Trent as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by water plants and algae, phosphate and specific pollutants. 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 DE72, which is treated before it reaches homes.
