Your river is the Cole from Source to Springfield, rated poor

The Environment Agency rated the Cole from Source to Springfield 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. 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 B14 do not include a PFAS result. Environment Agency monitoring found PFAS in 25 river and groundwater samples from 2 sites within 10 km of B14, the highest being PFecHS at 0.0049 µg/L about 8.8 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 B14?

The Environment Agency rated the Cole from Source to Springfield 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. 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 B14, which is treated before it reaches homes.
