Your river is the Sneyd Brook from Source to Tame (W/hampton Arm), rated bad

The Environment Agency rated the Sneyd Brook from Source to Tame (W/hampton Arm) as bad for ecological health in its 2025 assessment, meaning the river is severely damaged, with most of the expected wildlife missing. It is held back by insects and other small river life, water plants and algae and ammonia. 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.

Should I use a water filter in WS2?

WS2 water scored 9.2/10 with no contaminants above recommended levels. A filter is optional but can improve taste, especially if you notice a chlorine flavour. See our filter recommendations for your area.

Are there PFAS forever chemicals in WS2 water?

The tap-water tests we hold for WS2 do not include a PFAS result. Environment Agency monitoring found PFAS in 18 river and groundwater samples from 4 sites within 10 km of WS2, the highest being PFHxS (linear) at 0.0094 µg/L about 8.9 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 WS2?

The Environment Agency rated the Sneyd Brook from Source to Tame (W/hampton Arm) as bad for ecological health in its 2025 assessment, meaning the river is severely damaged, with most of the expected wildlife missing. It is held back by insects and other small river life, water plants and algae and ammonia. 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 WS2, which is treated before it reaches homes.
