Your river is the Soar from Sence to Rothley Brook, rated poor
The Environment Agency rated the Soar from Sence to Rothley Brook 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, phosphate and temperature. 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.

Environment Agency monitoring found PFAS in 154 river and groundwater samples from 6 sites within 10 km of LE21, the highest being 6:2 FTSA at 0.03 µg/L about 8.5 km away. These are environmental samples, not tests of tap water. The UK currently has no legal limit for PFAS in drinking water; the Drinking Water Inspectorate uses a 0.1 µg/L guideline for individual compounds. Reverse osmosis filters can reduce PFAS levels.
How clean is the river near LE21?
The Environment Agency rated the Soar from Sence to Rothley Brook 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, phosphate and temperature. 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. This is a rating of the river, not of tap water in LE21, which is treated before it reaches homes.
