Outside your tap

Your river is the Biddulph Brook, rated moderate

The Environment Agency rated the Biddulph Brook 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, ammonia 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.

The tap-water tests we hold for ST8 do not include a PFAS result. Environment Agency monitoring found PFAS in 52 river and groundwater samples from 3 sites within 10 km of ST8, the highest being PFOA at 0.0028 µg/L about 7.8 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 ST8?

The Environment Agency rated the Biddulph Brook 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, ammonia 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. This is a rating of the river, not of tap water in ST8, which is treated before it reaches homes.
