What's in a glass of B36 water

Every bubble is a substance the lab measured. The higher it floats, the closer it came to its legal limit, the dashed line at the top.

Fluoride came closest to a limit, at 54% of it. 14 of 17 substances used under a quarter of theirs.

Your river is the Cole from Springfield to Hatchford-Kingshurst Brook, rated poor

The Environment Agency rated the Cole from Springfield to Hatchford-Kingshurst 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 insects and other small river life, phosphate and dissolved oxygen. 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.

What contaminants are in B36 water?

We tested 20 contaminants in B36 water. None exceeded recommended safe levels. PFAS (forever chemicals) were also measured in rivers and groundwater within 10 km, though not in the tap-water tests themselves.

Who supplies water in B36?

B36 (Solihull) is supplied by Severn Trent. You can view their full profile and compliance data on our supplier page.

Should I use a water filter in B36?

B36 water scored 8.8/10 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 B36 water?

The tap-water tests we hold for B36 do not include a PFAS result. Environment Agency monitoring found PFAS in 116 river and groundwater samples from 8 sites within 10 km of B36, the highest being 6:2 FTSA at 0.025 µg/L about 5.6 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 B36?

The Environment Agency rated the Cole from Springfield to Hatchford-Kingshurst 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 insects and other small river life, phosphate and dissolved oxygen. 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 B36, which is treated before it reaches homes.
