Range across supply zones: 54–55 mg/L.
Vitens supplies this area, mainly from groundwater, and the sandy ridges of the Veluwe and Utrecht Hills typically give water with comparatively little lime. The reported hardness is 54.4 mg/L CaCO₃, with values from 53.5 to 55.3 mg/L depending on the street. Scale builds up only slowly here, and a softener is rarely needed.
Dutch suppliers report °dH; most networks are softened centrally to 5.6–8.4 °dH.
