SINAC data from the Ministry of Health for March 2026 put Paracuellos de Jarama at 33.2 mg/L CaCO₃, computed from published analyses. Madrid is supplied mostly by Canal de Isabel II, which draws from mountain reservoirs on granite and gneiss; that rock barely dissolves, so the water is lightly mineralised. At this level scale barely builds up on taps or appliances, and a softener is rarely worth installing.
