A sulfur-bearing calcium-sodium chloride spring. Weakly alkaline (pH 7.8 at the wellhead, 8.9 in the lab) and lukewarm at 28 degrees C, so it is reheated before bathing. Chloride dominates the anion side at over 98 percent — a salty, heat-retaining water — and the hydrogen sulfide content (total sulfur 22.4 mg/kg) carries the unmistakable rotten-egg note of H2S.
