Range across supply zones: 349–355 mg/L.
SINAC data from the Ministry of Health for May 2026 put Santa Fe at 352 mg/L CaCO₃, with readings from 349 to 355 mg/L. 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 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
- 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).
