A calcium- and sodium-led chloride spring sitting right at isotonic mineralization (9.1 g/kg dissolved solids) — close to seawater concentration, with strong heat-retaining body. At the wellhead the water carries a salty-bitter tang and a faint hint of hydrogen sulfide, giving it a distinctly mineral character.
