Range across supply zones: 27–673 mg/L.
For Puçol, SINAC (the Ministry of Health's water-supply system) records 450 mg/L CaCO₃, with readings from 27 to 673 mg/L as of September 2026, so it varies a lot with the supply point and the blend at the time. Supply in this part of Valencia mixes river water from the Turia and Júcar with wells in carbonate aquifers, and that geology is why hardness is high across much of the province. 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).
