Range across supply zones: 34–96 mg/L.

Halifax is supplied by Yorkshire Water, whose supply comes from a mix of upland reservoirs, rivers and boreholes; the company says water in the west comes off the moors while the east relies mostly on boreholes and groundwater. Reported hardness is 41.5 mg/L CaCO₃, ranging from 33.9 to 95.8 mg/L between supply zones. Reservoir water from moorland catchments carries little dissolved calcium, which keeps the water soft; scale is modest in kettles and showers, and most households manage without a softener.

UK suppliers report mg/L CaCO₃ and often Clark degrees (1 °Clark = 14.25 mg/L).
