Natural mineral waters of Russia, some CIS countries (Belarus, Moldova, Armenia, Azerbaijan, Georgia and Uzbekistan) and Eurasian countries carried to Chloride-Hydrocarbonate type have been investigated. The analytical dependences connecting, entered by authors, characteristic parameters of structure of waters (М, В, Ф) with independent variables of ionic structure and concentration are resulted. Based on the obtained data a mathematical model of the structure and properties of chloride-hydrocarbonate mineral waters is developed and the principles of formation of waters of a certain type and their distribution into groups and classes are formulated. A general system of classification of Eurasian mineral and low mineralization waters formed during the Late Alpine tectogenesis on the territory of European states has been developed. Results of research have shown an opportunity to apply characteristic parameters of structure of waters for the organization of national and interstate monitoring natural waters of various genesis and structure. Change of values of characteristic parameters of the mineral water counted on initial data of the chemical analysis of structure, can serve as a quantitative estimation of quality of mineral water and to be used for the organization of system of national and interstate monitoring waters. In this work it was shown that comparison of values of characteristic parameters of mineral waters and physiological liquids of plants, animals and the person can form a basis for development of recommendations on application of mineral waters for medical, rehabilitation and preventive application in a medical and biologic practice. Characteristic parameters of structure of waters can be used at examination of quality and conformity of mineral water to passport characteristics of declared analogue of reference water, and also for an establishment of the location of a source. Expansion of geography of a finding of sources of the mineral waters identified on their conformity to reference mineral waters on characteristic parameters М, В, Ф allows to use rationally regional natural water resources and to promote social development of territory of a location earlier sources of mineral waters not taken into consideration.
