Range across supply zones: 91–408 mg/L.
For Guadix, SINAC (the Ministry of Health's water-supply system) records 232.5 mg/L CaCO₃, with readings from 91 to 408 mg/L as of June 2026, so it varies a lot with the supply point and the blend at the time. In Granada province water comes from Sierra Nevada and limestone ranges as well as wells in the vega and basins, so hardness depends on which of those sources dominates. 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).
