Range across supply zones: 73–93 mg/L.
Abbanoa publishes semester tables for Sardinian municipalities, and only three network samples for Sorso fall in the period from late 2025 to 2026. They give a median of 72.9 mg/L CaCO₃, within a range of 72.9 to 92.9 mg/L, which is moderately hard water. The sample is small, so treat the figure as indicative. We have not confirmed the source of the supply, and scale should build up slowly at this level.
Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
