Water
Terme Reali di Valdieri Water, has been classified as medium-mineral according to its dry residue; it belongs to the group of the sulphureous sulphate-chloride-sodic hyperthermal waters (42-64 °C) and has a distinctly alkaline pH value (according to Marotta and Sica).
Under the therapeutic point of view it is a sulphureous water. The source temperature of 130 °C can be reached with a circulation pushing to 4500 meters of depth.
