Ruzzo Reti, the water company for the Teramo area, publishes test reports for Martinsicuro. The report we read, dated March 2026, gives a hardness of 320.0 mg/L CaCO₃, and the figures we hold run from 240.0 to 330.0 mg/L. That is very hard water. We have not verified where the town's water comes from, and nearby coastal towns differ, from 135.0 mg/L at San Benedetto del Tronto to 240.0 mg/L at Alba Adriatica. Expect heavy scale in kettles and water heaters.

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?

Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
