What's in a glass of LS22 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 34% of it. 18 of 20 substances used under a quarter of theirs.

Your river is the Wharfe from Collingham Beck to Tadcaster Weir, rated moderate

The Environment Agency rated the Wharfe from Collingham Beck to Tadcaster Weir as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by 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.

What contaminants are in LS22 water?

Who supplies water in LS22?

LS22 (Leeds) is supplied by Yorkshire Water. You can view their full profile and compliance data on our supplier page.

Is LS22 water hard or soft?

Water in LS22 (Leeds) has a hardness of 136 mg/L CaCO3, which is classified as moderately hard. This is a moderate hardness level.

Should I use a water filter in LS22?

LS22 water scored 9.3/10 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 LS22 water?

The tap-water tests we hold for LS22 do not include a PFAS result. Environment Agency monitoring found PFAS in 74 river and groundwater samples from 3 sites within 10 km of LS22, the highest being PFOS at 0.041 µg/L about 9.9 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 LS22?

The Environment Agency rated the Wharfe from Collingham Beck to Tadcaster Weir as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by 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 LS22, which is treated before it reaches homes.
