Range across supply zones: 255–308 mg/L.
The tap water in Wombwell comes from Yorkshire Water, which draws on moorland reservoirs in the west, rivers, and boreholes that are concentrated in the east of the region. Reported hardness is 292.2 mg/L CaCO₃, ranging from 254.6 to 308.2 mg/L between supply zones. The harder supply reflects borehole and groundwater sources, which pick up calcium and magnesium from the rock; it is hard to very hard water, so scale builds quickly on kettles, showers and heating elements and shortens appliance life unless treated.
UK suppliers report mg/L CaCO₃ and often Clark degrees (1 °Clark = 14.25 mg/L).

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
