Occurrence of thermal and mineralized waters as an opportunity for development of therapeutic resorts as the touristic attractions in Warsaw region

The thermal and mineralized waters in the subsurface of Sulejówek, Józefów, and Otwock towns of the Warsaw region have been analyzed. An initial assessment of the utilization of such waters based on deep boreholes and significance of these waters for development of the communities has been considered. The analysis shows that in the area of Sulejówek, Józefów and Otwock communes there are chloride and sodium waters in the aquifer of the Lower Cretaceous and the Jurassic of mineralization from about 10 to over 70 g/dm3, probably characterized by an increased content of specific components desirable in the case of waters used in balneotherapy – iodides (above 1 mg/dm3 in the lower cretaseous and lower jurassic) and divalent iron (over 10 mg/dm3 in the lower jurassic). The values of subsurface temperature in this area at a depth of 1000 m are about 35°C, at a depth of 2000 m the temperature exceeds 50°C. An optimist scenario includes a possibility of future development of touristic attractions in terms of therapeutic resorts in the Warsaw region.
