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 150.0 mg/L CaCO₃, which counts as hard water (a 2001 figure that may have changed since). Scale shows up on kettles and taps over weeks rather than days, and a descaling routine is usually enough.
Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
