What's in a glass of LS14 water

Every bubble is a substance the lab measured. The higher it floats, the closer it came to its legal limit, the dashed line at the top.

Trihalomethanes came closest to a limit, at 32% of it. 18 of 20 substances used under a quarter of theirs.

Your river is the Cock Beck Catchment (trib of Wharfe), rated bad

The Environment Agency rated the Cock Beck Catchment (trib of Wharfe) 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 fish 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.

Should I use a water filter in LS14?

Are there PFAS forever chemicals in LS14 water?

The tap-water tests we hold for LS14 do not include a PFAS result. Environment Agency monitoring found PFAS in 35 river and groundwater samples from 4 sites within 10 km of LS14, the highest being PFOA at 0.043 µg/L about 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 LS14?

The Environment Agency rated the Cock Beck Catchment (trib of Wharfe) 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 fish 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 LS14, which is treated before it reaches homes.
