What's in a glass of LE1 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.

Trihalomethanes came closest to a limit, at 61% of it. 15 of 17 substances used under a quarter of theirs.

Your river is the Soar from Sence to Rothley Brook, rated poor

The Environment Agency rated the Soar from Sence to Rothley 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 water plants and algae, phosphate and temperature. 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 LE1 water?

Should I use a water filter in LE1?

LE1 water scored 8.9/10 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 LE1 water?

The tap-water tests we hold for LE1 do not include a PFAS result. Environment Agency monitoring found PFAS in 154 river and groundwater samples from 6 sites within 10 km of LE1, the highest being 6:2 FTSA at 0.03 µg/L about 8.5 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 LE1?

The Environment Agency rated the Soar from Sence to Rothley 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 water plants and algae, phosphate and temperature. 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 LE1, which is treated before it reaches homes.
