Sodium Chloride spring
Arima's signature Kinsen (Gold Spring) — a 55:37 blend of the Ariake No. 1 and No. 2 wells emerging at 81 degrees Celsius. As iron-laden water meets the air it oxidises into the famous reddish-brown turbid bath, with a sharply salty, metallic taste. At 26.13 g/kg dissolved solids and 15,470 mg/kg of chloride it is a hypersaline chloride spring exceeding ocean salinity, with iron at 46.6 mg/kg giving the rust-red coating. Heavy, mineral-coated water that leaves a thick salt veil on the skin.
