Soft water. Kind to kettles, boilers and skin
You will not need a softener here, and you will use less soap and detergent than most of England.
Your river is the Dibbinsdale Brook and Clatter Brook, rated poor
The Environment Agency rated the Dibbinsdale Brook and Clatter Brook as poor for ecological health in its 2025 assessment, meaning the river is badly affected, with much of the expected wildlife missing. It is held back by dissolved oxygen, fish and 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.

Questions about CH62 water
Is CH62 tap water safe to drink?

Who supplies water in CH62?
CH62 (Wirral) is supplied by United Utilities. You can view their full profile and compliance data on our supplier page.
Is CH62 water hard or soft?
Water in CH62 (Wirral) has a hardness of 92 mg/L CaCO3, which is classified as moderately soft. This is a moderate hardness level.
Should I use a water filter in CH62?
CH62 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 CH62 water?
The tap-water tests we hold for CH62 do not include a PFAS result. Environment Agency monitoring found PFAS in 40 river and groundwater samples from 7 sites within 10 km of CH62, the highest being 6:2 FTSA at 0.0076 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 CH62?
The Environment Agency rated the Dibbinsdale Brook and Clatter Brook as poor for ecological health in its 2025 assessment, meaning the river is badly affected, with much of the expected wildlife missing. It is held back by dissolved oxygen, fish and 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 CH62, which is treated before it reaches homes.
