Range across supply zones: 239–312 mg/L.

The tap water in Kippax 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 261.0 mg/L CaCO₃, ranging from 238.7 to 312.2 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).
