Mineral character
Aproz has an extreme mineral profile driven by the evaporite geology of the Valaisian Alps. Calcium is 360 mg/L, magnesium 70 mg/L, sodium 6 mg/L, sulphate 930 mg/L, chloride 20 mg/L, and bicarbonate 250 mg/L. Hardness is 1,187 mg/L as CaCO₃ and TDS is approximately 1,638 mg/L. The combination of very high calcium and very high sulphate reflects gypsum dissolution along the filtration path — a characteristic also seen in Contrex and Valser among Swiss and eastern French waters.
