Your river is the Ryburn from Booth Dean Clough to R Calder, rated moderate

The Environment Agency rated the Ryburn from Booth Dean Clough to R Calder as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by fish, 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.

Should I use a water filter in HX6?

Are there PFAS forever chemicals in HX6 water?

The tap-water tests we hold for HX6 do not include a PFAS result. Environment Agency monitoring found PFAS in 6 river and groundwater samples from 1 sites within 10 km of HX6, the highest being PFOA at 0.0054 µg/L about 4.8 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 HX6?

The Environment Agency rated the Ryburn from Booth Dean Clough to R Calder as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by fish, 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 HX6, which is treated before it reaches homes.
