A sodium-calcium-magnesium sulfate spring with a bicarbonate sub-type — settled, mineral-rich body with bicarbonate softness layered in. Neutral pH and 46.6 °C at the source, with metasilicic acid at 127.7 mg/kg leaving a thin silica film for noticeably smoother skin. A modest 18 mg/kg of free hydrogen sulfide gives the water a faint rotten-egg note and a metallic edge at the wellhead.
