SINAC data from the Ministry of Health for September 2026 put Tavernes de la Valldigna at 250.5 mg/L CaCO₃, with readings from 250 to 251 mg/L. 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 is hard water: it leaves white marks on fittings and appliances need descaling fairly often.
