The hot water well was first drilled by Conoco Oil in the 1940's. It was part of the Florence oil exploration project. The well's production is coming from 1,096 feet down into the earth. The water coming from this depth is extremely hot, 132 degrees F and of exceptional water purity.
Water is cooled by the air convection, and water temperature is adjusted seasonally to maintain an ideal soaking temperature. During summer months, water temperature is maintained below body temperature. During winter months water temperature is maintained over 100 degrees. The blue hue of the water is directly connected to the mineral Travertine.
