The Eastern Carpathians are renowned for their mineral water resources, exploited since historical times for their therapeutic value. This paper summarizes the present state of knowledge on the chemical type of mineral waters from the point of view of dissolved constituents and associated gases, such as CO2, CH4 or H2S. The chemistry of mineral waters is highly influenced by the type of rocks they are leaching. Considering this aspect the mineral waters from the Eastern Carpathians are mainly influenced by the Neogene to Quaternary volcanic rocks of the Călimani-Gurghiu-Harghita Mountains, the sedimentary deposits of the Transylvanian Basin and the flysch deposits of the Carpathian arc.Four major chemical types were defined: sparkling, CO2-rich waters, NaCl-rich waters, sulfate or H2S-rich waters and geothermal waters. The overlapping chemical features give birth to the mixed type of waters found in the southern part of the Eastern Carpathians.
Key words: mineral waters, chemical type, major ions, CO2
