Your river is the Folly Brook and Salteye Brook., rated moderate

The Environment Agency rated the Folly Brook and Salteye 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 ammonia, organic pollution (bod) 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.
