Range across supply zones: 12–85 mg/L.
Mungyeong reports a median of 52.2 mg/L CaCO₃ for its treated water in 2025, with plants ranging from 12.0 to 85.0 mg/L. The region is mostly in the Nakdong River basin, fed by dams such as Andong, Imha and Hapcheon; this utility's own source is not confirmed here. At this level scale builds up slowly, so kettles and heating elements stay fairly clean and a softener is rarely needed. The spread between plants is wide, so check which plant serves your street.
Korean waterworks report hardness (경도) in mg/L CaCO₃; the drinking-water standard is 300 mg/L (1,000 mg/L for some sources).
