Matupá, in Mato Grosso, is served by Águas de Matupá. The 2025 reported hardness is 8.7 milligrams per litre as calcium carbonate, which is very soft. The published range is unusually wide, from 4.1 to 150.9 milligrams per litre, so the upper end is far from the typical value.
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.
