For Moaña, SINAC (the Ministry of Health's water-supply system) records 10 mg/L CaCO₃ as of June 2026. Galicia sits on granite and schist that dissolve poorly, and its water comes from rivers and upland sources with very little calcium and magnesium. This is very soft water: it leaves almost no limescale, and home treatment is seldom needed.
