Your river is the Frome (Brist) - Bradley Bk to conf Floating Hbr, rated moderate
The Environment Agency rated the Frome (Brist) - Bradley Bk to conf Floating Hbr as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by 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.
