A cold-mineral chloride spring (19.5 C at the wellhead, heated for bathing) led by sodium, calcium and magnesium. The 'iron-bearing' prefix on the certificate is earned — total iron 26 mg/kg, enough that the water emerges clear at the source and turns yellow-brown and slightly turbid by the time it reaches the lab. Neutral pH, moderately mineralized at 5.4 g/kg total solute, with a faint iron-rust note and a light salty-mineral taste on the lips.
