Range across supply zones: 19–30 mg/L.
Yeongam reports a median of 22.8 mg/L CaCO₃ for its treated water in 2025, with plants ranging from 18.5 to 29.5 mg/L. Water in this region comes mainly from the Yeongsan and Seomjin basins and their dams, such as Juam; 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.
Korean waterworks report hardness (경도) in mg/L CaCO₃; the drinking-water standard is 300 mg/L (1,000 mg/L for some sources).
