Rivieracqua lists three sampling points in Taggia, with hardness from 18 to 24 °F (180 to 240 mg/L CaCO₃) and a median of 22 °F (220 mg/L). That counts as very hard water, and the spread between points means the value at your tap may differ. The page carries no sampling date, so we use its July 2025 modification date, and we have not verified where the water comes from.
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).
