Your estuary is the Mersey, rated moderate

The Environment Agency rated the Mersey as moderate for ecological health in its 2025 assessment, meaning the estuary is noticeably changed by pollution or engineering. It is held back by insects and other small river life, specific pollutants and algal blooms. 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.

The tap-water tests we hold for L8 do not include a PFAS result. Environment Agency monitoring found PFAS in 38 river and groundwater samples from 6 sites within 10 km of L8, the highest being 6:2 FTSA at 0.0076 µg/L about 8.4 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 estuary near L8?

The Environment Agency rated the Mersey as moderate for ecological health in its 2025 assessment, meaning the estuary is noticeably changed by pollution or engineering. It is held back by insects and other small river life, specific pollutants and algal blooms. 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 estuary, not of tap water in L8, which is treated before it reaches homes.
