What's in a glass of HD1 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 49% of it. 19 of 20 substances used under a quarter of theirs.

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

The Environment Agency rated the Colne from River Holme to River 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 insects and other small river life, water plants and algae and ammonia. 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.

Questions about HD1 water

Is HD1 tap water safe to drink?

Based on the latest tests, HD1 (Kirklees) water scores 9.6/10, which is safe. 0 of 25 tested contaminants exceeded recommended levels. Water is supplied by Yorkshire Water.

What contaminants are in HD1 water?

We tested 25 contaminants in HD1 water. None exceeded recommended safe levels. PFAS (forever chemicals) were also measured in rivers and groundwater within 10 km, though not in the tap-water tests themselves.

Who supplies water in HD1?

HD1 (Kirklees) is supplied by Yorkshire Water. You can view their full profile and compliance data on our supplier page.

Is HD1 water hard or soft?

Water in HD1 (Kirklees) has a hardness of 44 mg/L CaCO3, which is classified as soft. Soft water is gentle on appliances and skin.

Should I use a water filter in HD1?

HD1 water scored 9.6/10 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 HD1 water?

The tap-water tests we hold for HD1 do not include a PFAS result. Environment Agency monitoring found PFAS in 66 river and groundwater samples from 6 sites within 10 km of HD1, the highest being PFPeA at 0.24 µg/L about 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 HD1?

The Environment Agency rated the Colne from River Holme to River 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 insects and other small river life, water plants and algae and ammonia. 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 HD1, which is treated before it reaches homes.
