Your river is the Smestow Bk - source to conf Wom-Penn Bk, rated moderate

The Environment Agency rated the Smestow Bk - source to conf Wom-Penn Bk as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by phosphate, insects and other small river life 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.

Environment Agency monitoring found PFAS in 12 river and groundwater samples from 5 sites within 10 km of WV3, the highest being 6:2 FTSA at 0.016 µg/L about 6.9 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 WV3?

The Environment Agency rated the Smestow Bk - source to conf Wom-Penn Bk as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by phosphate, insects and other small river life 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 WV3, which is treated before it reaches homes.
