For Alcañiz, SINAC (the Ministry of Health's water-supply system) records 354 mg/L CaCO₃, with readings from 353 to 437 mg/L as of September 2026. In this part of Aragón the water comes from the Ebro, its tributaries and local sources, and crosses ground with gypsum and limestone that raises mineral content. This hardness forms limescale quickly in kettles, water heaters and washing machines; in a home, a softener is usually worth considering.

What it means at home

- 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).
