Your river is the Blythe from Source to Cuttle Brook, rated poor

The Environment Agency rated the Blythe from Source to Cuttle Brook 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 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 B90 water?

The tap-water tests we hold for B90 do not include a PFAS result. Environment Agency monitoring found PFAS in 116 river and groundwater samples from 5 sites within 10 km of B90, the highest being PFOS (linear) at 0.0093 µg/L about 9.3 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 B90?

The Environment Agency rated the Blythe from Source to Cuttle Brook 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 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 B90, which is treated before it reaches homes.
