Range across supply zones: 14–100 mg/L.
SINAC data from the Ministry of Health for October 2026 put Cangas del Narcea at 41 mg/L CaCO₃, with readings from 14 to 100 mg/L, so it varies a lot with the supply point and the blend at the time. In Asturias water is taken from rivers and reservoirs in the Cantabrian mountains; limestone and slate alternate in the central area, so hardness differs between municipalities. This is very soft water: it leaves almost no limescale, and home treatment is seldom needed.
