Your river is the Anker from Wem Brook to River Sence, rated moderate

The Environment Agency rated the Anker from Wem Brook to River Sence as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by phosphate, fish and insects and other small river life. 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 CV10 do not include a PFAS result. Environment Agency monitoring found PFAS in 10 river and groundwater samples from 1 sites within 10 km of CV10, the highest being PFBS at 0.0029 µg/L about 7.2 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 CV10?

The Environment Agency rated the Anker from Wem Brook to River Sence as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by phosphate, fish and insects and other small river life. 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 CV10, which is treated before it reaches homes.
