What's in a glass of HD9 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 56% of it. 19 of 20 substances used under a quarter of theirs.

Your river is the Holme from Source to New Mill Dike, rated moderate

The Environment Agency rated the Holme from Source to New Mill Dike 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. 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.

Who supplies water in HD9?

HD9 (Kirklees) is supplied by Yorkshire Water. You can view their full profile and compliance data on our supplier page.

Is HD9 water hard or soft?

Should I use a water filter in HD9?

HD9 water scored 9.5/10 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 HD9 water?

The tap-water tests we hold for HD9 do not include a PFAS result. Environment Agency monitoring found PFAS in 24 river and groundwater samples from 4 sites within 10 km of HD9, the highest being PFBA at 0.0077 µg/L about 8.1 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 HD9?

The Environment Agency rated the Holme from Source to New Mill Dike 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. 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 HD9, which is treated before it reaches homes.
