SINAC data from the Ministry of Health for May 2026 put Torrelodones at 32 mg/L CaCO₃. 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. This is very soft water: it leaves almost no limescale, and home treatment is seldom needed.
