This figure is over 3 years old; hardness may have changed.
The Marche region's drinking water is a mix of Apennine springs and valley groundwater, delivered by the local utilities. The only figure we have is 210.0 mg/L CaCO₃, with readings from 140.0 to 290.0 mg/L, which counts as very hard water (a 2001 figure that may have changed since). Values differ across the area, so check your own address before buying a softener; expect scale on kettles, shower heads and in the water heater, and descaling about as often as a hard-water kitchen requires.
Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.
