Your river is the Tees Estuary (S Bank), rated moderate

The Environment Agency rated the Tees Estuary (S Bank) as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by insects and other small river life. 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 TS10?

TS10 water scored 9.3/10 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 TS10 water?

The tap-water tests we hold for TS10 do not include a PFAS result. Environment Agency monitoring found PFAS in 23 river and groundwater samples from 2 sites within 10 km of TS10, the highest being PFBA at 0.0073 µg/L about 9.3 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 TS10?

The Environment Agency rated the Tees Estuary (S Bank) as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. It is held back by insects and other small river life. 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 TS10, which is treated before it reaches homes.
