Your river is the Penk from Source toSaredon Brook, rated poor

The Environment Agency rated the Penk from Source toSaredon 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 fish, 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.

Should I use a water filter in WV8?

With 1 contaminant above recommended levels in WV8, a water filter could help. A reverse osmosis or activated carbon filter is recommended for PFAS removal. See our filter recommendations for your area.

Are there PFAS forever chemicals in WV8 water?

The tap-water tests we hold for WV8 do not include a PFAS result. Environment Agency monitoring found PFAS in 6 river and groundwater samples from 3 sites within 10 km of WV8, the highest being 6:2 FTSA at 0.016 µg/L about 7.3 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 WV8?

The Environment Agency rated the Penk from Source toSaredon 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 fish, 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 WV8, which is treated before it reaches homes.
