Your river is the Bailey Brook Catchment (trib of Erewash), rated poor

The Environment Agency rated the Bailey Brook Catchment (trib of Erewash) 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 insects and other small river life, water plants and algae and dissolved oxygen. 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.

Are there PFAS forever chemicals in DE75 water?

The tap-water tests we hold for DE75 do not include a PFAS result. Environment Agency monitoring found PFAS in 92 river and groundwater samples from 13 sites within 10 km of DE75, the highest being 6:2 FTSA at 0.061 µg/L about 8.9 km away. These are environmental samples, not tests of tap water. The UK currently has no legal limit for PFAS in drinking water; the Drinking Water Inspectorate uses a 0.1 µg/L guideline for individual compounds. Reverse osmosis filters can reduce PFAS levels.

How clean is the river near DE75?

The Environment Agency rated the Bailey Brook Catchment (trib of Erewash) 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 insects and other small river life, water plants and algae and dissolved oxygen. 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 DE75, which is treated before it reaches homes.
