Twenty-seven bottled waters from different regions of Serbia and Croatia were characterized by 23 chemical and physico-chemical composition parameters within the framework of the Pan-European project about geochemistry of bottled water in Europe launched in 2007 by the European Geological Surveys Geochemistry Expert Group. The reported analytical results were used for chemometric characterization by means of univariable and multivariable tools (i.e. principal component analysis). Results showed a wide variation in the chemical composition of bottled waters, with differences in chemical composition observed in the region due to the geological and environmental factors. Generally, there are moderate to high correlation among the large number of analyzed parameters. As shown by multivariable analysis a lack of clear separation of the Serbian and Croatian bottled waters indicates their high degree of similarities in the terms of analyzed chemical composition and physico-chemical parameters.
