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 280.0 mg/L CaCO₃ across 3 supply zones, with readings from 150.0 to 440.0 mg/L, which counts as very hard water (a 2002 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.

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).
