Simple
Classification
Sodium-Calcium Chloride spring
A hot (57.2 °C) simple thermal spring — sodium and chloride dominate the ionic balance, but total dissolved solids (948.6 mg/kg) sit just below the 1,000 mg/kg threshold, so the certificate classifies it as simple thermal spring rather than a true chloride spring. Weakly alkaline at pH 7.9, soft on the skin, with a faint chloride character running underneath.
