Classification
Sodium-Magnesium-Calcium Bicarbonate-Sulfate spring
A hot (48.8 °C) bicarbonate-sulfate spring led by sodium, magnesium and calcium. The wellhead water is colorless and clear with a faintly metallic taste, but on standing it develops a strong yellow turbidity — a glimpse of the iron it carries. Metasilicic acid at a generous 211 mg/kg leaves the kind of thin silica film that makes skin feel noticeably smoother afterwards.
