【 摘 要 】

Groundwater resources of mineral and thermo-mineral water are invaluable for planning a sustainable spatial and economic development of the Rogaka Slatina area, which requires a protection of this natural heritage. Numerous previous investigations of Rogaka groundwaters were subjects to balneology and to demands for larger exploitation quantities, that is why information are missing that are essential for definition of the Rogaka fractured aquifer system with mineral and thermo-mineral water and for its protection. The isotopic investigations of groundwaters stored in the Rogaka Slatina fractured aquifer system were performed aiming at answering open questions on the groundwater recharge and dynamics, on connections between different types of aquifers and on solute transport. Environmental isotopes2H,18O,3H,13C of dissolved inorganic carbon and14C were analysed in mineral, thermo-mineral and spring waters. Results indicated the source and mechanism of groundwater recharge, its renewability, a transit time distribution, hydraulic interrelationships, the groundwater origin and its evolution due to effects of water-rock interaction. The mean residence time estimates of mineral and thermo- mineral water in the aquifer are between 3400 and 14000 years. On the other hand, the mixing processes between younger and older waters or mineral and spring waters are reflected as well as waters that infiltrated predominantly after the 1960s. These suggest the vulnerability of the research systems to man-made impacts. The presented results coupled with available information on a physical hydrogeology and water chemistry asses the optimal balance between the environmental protection and economic use of mineral water resources in the study area. They are essential for the protection strategy development of mineral and thermo-mineral water in the Rogaka Slatina area bringing together the state administration and local authorities and stakeholders.
