Your river is the Coal Bk - source to conf R Tern, rated moderate

The Environment Agency rated the Coal Bk - source to conf R Tern 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 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. Its ecological rating has improved since the previous assessment.

The tap-water tests we hold for TF9 do not include a PFAS result. Environment Agency monitoring found PFAS in 4 river and groundwater samples from 2 sites within 10 km of TF9, the highest being 6:2 FTSA at 0.0082 µg/L about 9.7 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 TF9?

The Environment Agency rated the Coal Bk - source to conf R Tern 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 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. Its ecological rating has improved since the previous assessment. This is a rating of the river, not of tap water in TF9, which is treated before it reaches homes.
