Classification
Sodium Carbonate-Bicarbonate spring
Well No. 2 at Enzan Onsen is a simple sulfur cold-mineral spring with strongly alkaline character (pH 10.1). Source temperature is just 23.8 degC, so it is a cold-mineral spring heated for bathing rather than served at the wellhead. Total dissolved solids are light at 169 mg/kg, but the water carries hydrogen sulfide ions enough to leave a faint sulfurous taste and rotten-egg note at the source. The strong alkalinity gives the pronounced slippery 'beauty-water' feel, the family this spring belongs to.
