Your river is the Stour (Worcs) source to conf Smestow Bk, rated poor

The Environment Agency rated the Stour (Worcs) source to conf Smestow Bk 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 fish, 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.

Are there PFAS forever chemicals in DY2 water?

The tap-water tests we hold for DY2 do not include a PFAS result. Environment Agency monitoring found PFAS in 31 river and groundwater samples from 4 sites within 10 km of DY2, the highest being PFHxS (linear) at 0.0094 µg/L about 7.5 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 DY2?

The Environment Agency rated the Stour (Worcs) source to conf Smestow Bk 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 fish, 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 DY2, which is treated before it reaches homes.
