Your river is the Ford Brook from Source to River Tame, rated moderate
The Environment Agency rated the Ford Brook from Source to River Tame as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by insects and other small river life, ammonia 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 WS3 do not include a PFAS result. Environment Agency monitoring found PFAS in 5 river and groundwater samples from 3 sites within 10 km of WS3, the highest being PFBA at 0.0033 µg/L about 8.8 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 WS3?
The Environment Agency rated the Ford Brook from Source to River Tame as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by insects and other small river life, ammonia 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 WS3, which is treated before it reaches homes.
