Much of the water in the Valencia area comes from the Júcar and Turia rivers via the Júcar-Turia canal, plus local wells. Official analyses put the water at 440 mg/L CaCO₃, very hard. Limestone and sedimentary rock dissolve plenty of calcium and magnesium, hence the high hardness. Scale on taps and shower screens is common, and water-heater elements foul sooner.
