The importance of an integrated analytic approach to the study of physicochemical characteristics of natural thermal waters used for pelotherapy aims: Perspectives for reusing cooled thermal waters for treatments related to thermalism applications

The integrated study of complex materials intended as non-homogeneous matrices containing elements having a different nature and concentrations, give abroad view of liquid and solid complex systems. Thermal water is considered to be a natural complex system composed of bioinorganic constituents. Generally, the chemical pattern of thermal groundwater varies significantly depending on the geological and hydrogeological settings. The Euganean Thermal Basin (ETB) also named Euganean Thermal Area – ETA is the most important thermal field in northern Italy. Thermal waters of the Jelenia Gora Geothermal Area (JGA) occur in carboniferous granitoids of the Karkonosze massif. Granitoids build the crystalline basement of the Jelenia Gora Valley and the Karkonosze Mountains range which limits the Jelenia Gora Valley from the south. The contact and combined action between thermal waters and the mineralogical components of a mud produce an evolution of viscoelastic and surface energy properties of the muddy matrix in time, called the maturation process.
