What's in a glass of M24 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 38% of it. 15 of 16 substances used under a quarter of theirs.

Your river is the Irk (Source to Wince Brook), rated moderate

The Environment Agency rated the Irk (Source to Wince Brook) as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by fish, insects and other small river life and 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 M24 water?

Who supplies water in M24?

M24 (Rochdale) is supplied by United Utilities. You can view their full profile and compliance data on our supplier page.

Is M24 water hard or soft?

Water in M24 (Rochdale) has a hardness of 31 mg/L CaCO3, which is classified as soft. Soft water is gentle on appliances and skin.

Should I use a water filter in M24?

M24 water scored 9.4/10 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 M24 water?

The tap-water tests we hold for M24 do not include a PFAS result. Environment Agency monitoring found PFAS in 88 river and groundwater samples from 4 sites within 10 km of M24, the highest being PFBA at 0.05 µg/L about 7.1 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 M24?

The Environment Agency rated the Irk (Source to Wince Brook) as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by fish, insects and other small river life and 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 M24, which is treated before it reaches homes.
