The thermal bath in Gračanica is being formed in the settlement of Šenik near Gračanica (Spatial plan for the areas of Tuzla Canton, 2005-2015, Tuzla). In the period from 1979 to 1992, intensive geological and hydrological research of thermal waters in Gračanica was carried out. Structurally investigated: exploitation drilling, quality, physico-chemical composition, indications and application of thermo- mineral waters in the municipality of Gračanica. (Baraković, 2004.) Gračanica waters belong to the group of thermal highly mineralized waters, with a large amount of natural carbon dioxide. Based on the results of the examination, and extensive professional-medical and clinically proven documentation, the clinical use of thermo-mineral water in Gračanica for the rehabilitation and treatment of rheumatic diseases was approved.
