Your river is the Wood Brook Catchment (trib of Soar), rated poor

The Environment Agency rated the Wood Brook Catchment (trib of Soar) 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 fish, dissolved oxygen 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.

Should I use a water filter in LE11?

LE11 water scored 9.2/10 with no contaminants above recommended levels. A filter is optional but can improve taste, especially if you notice a chlorine flavour. See our filter recommendations for your area.

Are there PFAS forever chemicals in LE11 water?

The tap-water tests we hold for LE11 do not include a PFAS result. Environment Agency monitoring found PFAS in 35 river and groundwater samples from 4 sites within 10 km of LE11, the highest being 6:2 FTSA at 0.03 µg/L about 9.4 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 LE11?

The Environment Agency rated the Wood Brook Catchment (trib of Soar) 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 fish, dissolved oxygen 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. This is a rating of the river, not of tap water in LE11, which is treated before it reaches homes.
