You will not need a softener here, and you will use less soap and detergent than most of England.
Your river is the Kenn, rated poor
The Environment Agency rated the Kenn 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 water plants and algae 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.
