A simple sulfur spring of the hydrogen-sulfide type. The water runs colorless, clear and tasteless at the wellhead but carries the faint rotten-egg note of H₂S that gives a sulfur spring its signature. Mineralization is light at 298 mg/kg and the reaction is weakly acidic, so the bath feels gentle rather than sharp, while 72.7 mg/kg of metasilicic acid leaves the skin noticeably smoother. The posted certificate documents the water for atopic dermatitis, psoriasis vulgaris, chronic eczema, pyoderma and peripheral circulation disorders. Bathing only — the panel states that drinking requires permission from the public health office.
