Range across supply zones: 20–30 mg/L.
The hardness recorded in SINAC for Lalín is 25 mg/L CaCO₃, with readings from 20 to 30 mg/L, based on March 2026 data. Galicia sits on granite and schist that dissolve poorly, and its water comes from rivers and upland sources with very little calcium and magnesium. At this level scale barely builds up on taps or appliances, and a softener is rarely worth installing.
