Range across supply zones: 17–19 mg/L.

Copasa reports 18.0 mg/L CaCO₃ for Iturama in Minas Gerais, with samples between 17.0 and 19.0 mg/L. That is soft water and a very narrow spread, so the figure should hold across the network. Scale in kettles and heaters is likely to build slowly. We have not verified the source water.

Portaria GM/MS nº 888/2021 sets a maximum of 300 mg/L CaCO₃ for total hardness (dureza total); operators report it in mg/L to SISAGUA.
