The occurrence of Krynica mineral waters is associated with a flysch reservoir of groundwater of the Poprad river tributaries. These are naturally carbonated mineral waters, accompanied by regular waters of the surface zone. In some local deep holes, specific chloride mineral waters, called “Zubers” have been discovered. The first mention of curative properties of the Krynica springs come from the mid-18th century. They are used to cure digestive system, urinary tract and metabolic diseases.
