Sodium-Calcium Chloride spring

A sodium-calcium chloride spring of low tonicity and weakly alkaline pH (38.2 °C at the wellhead). With 1,245 mg/kg of dissolved solids it is moderately mineralized, soft on the skin, with a very faint salty note. A generous 118 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
