A sodium chloride cold-mineral spring that is also markedly iodine-rich. The salty, heat-retaining chloride water is moderately to richly mineralized at 9,050 mg/kg of dissolved solids, leaving a mineral film on the skin. Because the source emerges below 25 °C, it is a cold-mineral spring heated for bathing. With iodide at 22.2 mg/kg the water belongs to the iodine-bearing family and tends to discolour on contact with air.
