Range across supply zones: 25–335 mg/L.
SINAC data from the Ministry of Health for September 2026 put Mogán at 149.5 mg/L CaCO₃, with readings from 25 to 335 mg/L, so it varies a lot with the supply point and the blend at the time. Gran Canaria draws much of its water from seawater desalination, blended with volcanic groundwater in some areas. Some scale shows on shower screens, kettles and taps, and a scale-reduction filter can be reasonable if you want to protect appliances.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
