The geochemistry of the major components and trace elements in Slovenian bottled water available on the market in 2004 and 2008 was studied. The waters were predominantly from the Radenska and Rogaška Slatina mineral water source region. In this paper, a comparison of two data sets from two time periods was performed based on the Kolmogorov–Smirnov independent two-sample test. The bottled waters in the data sets were in agreement with drinking water and mineral water standards. Discrepancies were only present for B and Ni in highly mineralised waters. Analyses of the labels on the bottle packaging showed that the analytical results were in general agreement with the values reported on the labels. At the same time, the values reported on the labels by the producers showed that the chemical compositions of products available on the market for longer time periods vary. Slovenian bottled waters are predominantly controlled by a CaCO3–CO2–H2O system where Na, Cl− and SO42− are present as the major components, in different combinations.
