Your river is the Mobberley Bk, rated moderate

The Environment Agency rated the Mobberley Bk as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by insects and other small river life, water plants and algae 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.

Are there PFAS forever chemicals in ST10 water?

The tap-water tests we hold for ST10 do not include a PFAS result. Environment Agency monitoring found PFAS in 47 river and groundwater samples from 5 sites within 10 km of ST10, the highest being PFOA at 0.017 µg/L about 8.4 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 ST10?

The Environment Agency rated the Mobberley Bk as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by insects and other small river life, water plants and algae 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 ST10, which is treated before it reaches homes.
