SINAC data from the Ministry of Health for September 2026 put Carcaixent at 178.5 mg/L CaCO₃, with readings from 102 to 330 mg/L, so it varies a lot with the supply point and the blend at the time. Tap water in Valencia province comes mainly from the Turia and Júcar basins and from local aquifers that run through limestone and marl rich in calcium and magnesium. Some scale shows on shower screens, kettles and taps, and a scale-reduction filter can be reasonable if you want to protect appliances.
