A gentle simple thermal water: at 467 mg/kg of dissolved solids it is lightly mineralized and easy on the body, weakly alkaline and soft on the skin. Bicarbonate leads the anion side with chloride behind it, so the composition reads quiet rather than sharp. The one thing you notice is a faint sulfur note caught at the wellhead — the laboratory sample, tested 24 hours after collection, had gone completely odorless, so that trace of sulfur belongs to the water only while it is fresh from the source. The certificate defers indications and contraindications to a separate appendix that is not part of this document.
