For Benetússer, SINAC (the Ministry of Health's water-supply system) records 440 mg/L CaCO₃ as of June 2026. 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.
