A magnesium- and sodium-led bicarbonate-sulfate spring — weakly alkaline and soft on the skin, the bicarbonate softness layered with quiet sulfate body. At the wellhead the water is faintly yellow and clear with a metallic iron note, and turns slightly cloudy as the iron oxidizes on standing. A generous 234 mg/kg of metasilicic acid leaves the kind of thin silica film that makes skin feel noticeably smoother afterwards.
