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 Sett, rated moderate
The Environment Agency rated the Sett 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.

Who supplies water in SK22?
SK22 (High Peak) is supplied by Severn Trent. You can view their full profile and compliance data on our supplier page.
Is SK22 water hard or soft?
No hardness reading has been published for SK22 itself. Across the SK postcode area the typical value is 47 mg/L CaCO3, which is classified as soft. Soft water is gentle on appliances and skin.
Should I use a water filter in SK22?
SK22 water scored 8.7/10 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 SK22 water?
The tap-water tests we hold for SK22 do not include a PFAS result. Environment Agency monitoring found PFAS in 93 river and groundwater samples from 7 sites within 10 km of SK22, the highest being PFOA at 0.011 µg/L about 9.5 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 SK22?
The Environment Agency rated the Sett 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 SK22, which is treated before it reaches homes.
