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 Irwell / Manchester Ship Canal (Irk to confluence with Upper Mersey), rated moderate
The Environment Agency rated the Irwell / Manchester Ship Canal (Irk to confluence with Upper Mersey) as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by ammonia and phosphate. 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.

The Environment Agency rated the Irwell / Manchester Ship Canal (Irk to confluence with Upper Mersey) as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by ammonia and phosphate. 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.
