Your river is the Calder from River Colne to River Chald, rated moderate

The Environment Agency rated the Calder from River Colne to River Chald 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, fish and insects and other small river life. 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 WF5?

WF5 water scored 9.2/10 with no contaminants above recommended levels. A filter is optional but can improve taste, especially if you notice a chlorine flavour. See our filter recommendations for your area.

Are there PFAS forever chemicals in WF5 water?

The tap-water tests we hold for WF5 do not include a PFAS result. Environment Agency monitoring found PFAS in 90 river and groundwater samples from 6 sites within 10 km of WF5, the highest being PFBS at 0.047 µg/L about 2.2 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 WF5?

The Environment Agency rated the Calder from River Colne to River Chald 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, fish and insects and other small river life. 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 WF5, which is treated before it reaches homes.
