Outside your tap

Your river is the Red Strine - source to conf R Strine, rated bad

The Environment Agency rated the Red Strine - source to conf R Strine as bad for ecological health in its 2025 assessment, meaning the river is severely damaged, with most of the expected wildlife missing. It is held back by water plants and algae, insects and other small river life 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.

How clean is the river near TF2?

The Environment Agency rated the Red Strine - source to conf R Strine as bad for ecological health in its 2025 assessment, meaning the river is severely damaged, with most of the expected wildlife missing. It is held back by water plants and algae, insects and other small river life 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 TF2, which is treated before it reaches homes.
