A simple weak-radioactive spring of the radon-bearing "hormesis" tradition, carrying a notable 159.1 Bq/kg of radon. Mineralization is light at just 0.17 g/kg, and the water is mildly alkaline and soft on the skin. Almost colorless, transparent, tasteless and odorless, it is a gentle, low-mineral water whose defining feature is its radon content.
