A sharp, prickly acidic spring (pH 2.5 at the source) that is also markedly iron-rich, oxidizing reddish-brown on contact with air. At the wellhead the water carries a red tint with a strong metallic iron note in taste and smell. With total iron around 30 mg/kg it bites a little on the skin, and as a cold-mineral source below 25 °C it is reheated for bathing.
