The hardness recorded in SINAC for Roses is 180 mg/L CaCO₃, based on July 2026 data. Much of the water in this part of Girona comes from wells and aquifers in the Empordà and along the coast, in ground rich in limestone and carbonate sediments. This is hard water: it leaves white marks on fittings and appliances need descaling fairly often.

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).
