Classification
Sodium Chloride-HSiO3 spring
A sodium-led alkaline simple sulfur spring. Total dissolved solids are light at just 306 mg/kg, but total sulfur reaches 2.1 mg/kg — enough to qualify as a sulfur-bearing source. At 32 degrees Celsius it sits in the low-temperature class and is reheated for bathing; the alkaline pH gives the water a soft, gentle feel on the skin.
