Middling hardness. Some scale, slowly

Your river is the Durleigh Brook, rated moderate
The Environment Agency rated the Durleigh 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. 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.
