The tank is as full as the score. The specks are the minerals that make water hard.

What to do about it

Hard water: compare softener quotes

At 195 mg/L a softener is the only thing that stops limescale. Filters do not soften water.

It pays for itself in most homes at this hardness, through a boiler that stays efficient and appliances that last.

This is the water that furs up kettles

Hard on the UK scale. It is fine to drink. It is hard on boilers, showers, skin and anything that heats water, and a jug or tap filter will not change that.

Your river is the Chald from Source to River Calder, rated moderate

The Environment Agency rated the Chald from Source to River Calder as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. 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.

Questions about WF1 water

Is WF1 tap water safe to drink?

Based on the latest tests, WF1 (Wakefield) water scores 9.4/10, which is safe. 0 of 25 tested contaminants exceeded recommended levels. Water is supplied by Yorkshire Water.

What contaminants are in WF1 water?

We tested 25 contaminants in WF1 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 WF1?

WF1 (Wakefield) is supplied by Yorkshire Water. You can view their full profile and compliance data on our supplier page.

Is WF1 water hard or soft?

Water in WF1 (Wakefield) has a hardness of 195 mg/L CaCO3, which is classified as hard. Hard water can cause limescale buildup. A water softener or filter jug may help.

Should I use a water filter in WF1?

WF1 water scored 9.4/10 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 WF1 water?

The tap-water tests we hold for WF1 do not include a PFAS result. Environment Agency monitoring found PFAS in 91 river and groundwater samples from 6 sites within 10 km of WF1, the highest being PFBS at 0.047 µg/L about 4.3 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 WF1?

The Environment Agency rated the Chald from Source to River Calder as moderate for ecological health in its 2025 assessment, meaning the river is noticeably changed by pollution or engineering. 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 WF1, which is treated before it reaches homes.
