Mixed source
Sodium-Calcium Chloride-Sulfate spring
A blended spring drawing on three wells — Oka No. 191, No. 152, and No. 137 — sampled from the storage tank in Ito's Suehiro neighborhood. The wellhead temperature is a hot 44.2 °C, but the total dissolved solids sit at a light 808 mg/kg, placing it firmly in simple thermal territory. Weakly alkaline at pH 8.2, the water reads soft on the skin, with sodium leading the cations and chloride and sulfate sharing the anion column almost evenly.
