Range across supply zones: 228–295 mg/L.
Yorkshire Water supplies Haxby from a network that blends reservoir, river and borehole sources, and the company links harder water in the east of the region to its borehole and groundwater supplies. Reported hardness is 277.2 mg/L CaCO₃, ranging from 228.4 to 294.7 mg/L between supply zones. The harder supply reflects borehole and groundwater sources, which pick up calcium and magnesium from the rock; expect visible limescale on taps, kettles and in boilers; a softener or scale inhibitor is worth considering, especially for hot-water systems.
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).
