A calcium- and magnesium-led sulfate cold-mineral spring. The wellhead measures just 10.9 °C, so the water is reheated for bathing as a cold-mineral spring. Neutral pH with around 1,016 mg/kg of dissolved solids — moderately mineralized, settled and sulfate-driven. The water carries a faint yellow tint at the source and a soft metallic, iron-leaning note on the tongue.
