Your river is the Hockley Brook Catchment (trib of Rea), rated moderate
The Environment Agency rated the Hockley Brook Catchment (trib of 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 specific pollutants. 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 B2 water?
The tap-water tests we hold for B2 do not include a PFAS result. Environment Agency monitoring found PFAS in 34 river and groundwater samples from 4 sites within 10 km of B2, the highest being PFHxS (linear) at 0.0094 µg/L about 5.8 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 B2?
The Environment Agency rated the Hockley Brook Catchment (trib of 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 specific pollutants. 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 B2, which is treated before it reaches homes.
