Range across supply zones: 32–52 mg/L.
The water comes from reservoirs and intakes in the Tagus and Alagón basins, over granite. Official analyses put the water at 42 mg/L CaCO₃, soft, with values between 32 and 52 mg/L. Low-mineral, siliceous terrain explains the low calcium and magnesium. Appliances gather little scale; it is enough to dose detergent sensibly.
