A sodium-led chloride spring with bicarbonate softness layered in, drawn from a well sunk 1,492 metres beneath the site. It is neutral in pH and moderately mineralized at 4,146 mg/kg — the water looks clear and colorless, but it tastes strongly salty with a very faint sulfur note behind it. At 39.7 °C the source arrives just short of comfortable bathing warmth, so the bath is reheated and served through recirculating filtration with disinfection rather than as fresh free-flow.
