Your estuary is the Kingsbridge, rated poor

The Environment Agency rated the Kingsbridge as poor for ecological health in its 2025 assessment, meaning the estuary is badly affected, with much of the expected wildlife missing. It is held back by seaweed, insects and other small river life and nitrogen. 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. Its ecological rating has dropped since the previous assessment.

How clean is the estuary near TQ7?

The Environment Agency rated the Kingsbridge as poor for ecological health in its 2025 assessment, meaning the estuary is badly affected, with much of the expected wildlife missing. It is held back by seaweed, insects and other small river life and nitrogen. 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. Its ecological rating has dropped since the previous assessment. This is a rating of the estuary, not of tap water in TQ7, which is treated before it reaches homes.
