Your river is the Tame (W/ton Arm) source to conf Oldbury, rated moderate

The Environment Agency rated the Tame (W/ton Arm) source to conf Oldbury 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, organic pollution (bod) 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.

Environment Agency monitoring found PFAS in 18 river and groundwater samples from 4 sites within 10 km of WV13, the highest being PFHxS (linear) at 0.0094 µg/L about 10 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 WV13?

The Environment Agency rated the Tame (W/ton Arm) source to conf Oldbury 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, organic pollution (bod) 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 WV13, which is treated before it reaches homes.
