Your river is the Bourn Brook from Source to R Rea, rated moderate

The Environment Agency rated the Bourn Brook from Source to R Rea as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. 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.

The tap-water tests we hold for B32 do not include a PFAS result. Environment Agency monitoring found PFAS in 13 river and groundwater samples from 1 sites within 10 km of B32, the highest being PFHxS (linear) at 0.0094 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 B32?

The Environment Agency rated the Bourn Brook from Source to R Rea as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. 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 B32, which is treated before it reaches homes.
