Range across supply zones: 55–166 mg/L.
SINAC data from the Ministry of Health for April 2025 put Bergara at 144.5 mg/L CaCO₃, with readings from 55 to 166 mg/L, so it varies a lot with the supply point and the blend at the time. In the Basque Country water comes from reservoirs and springs on the Cantabrian side, with limestone and marl in the massifs and sandstone elsewhere; hardness runs from low to moderate. 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).
