Abstract: Ninety-three water samples were categorized into five classes as the tap, mineral, mineral carbonated, spring, and spring carbonated water, or, alternatively, into four or three categories — with all spring water samples together or as tap, mineral, and spring water, respectively. The samples originated from four European countries and thirty-one chemical descriptors (concentrations of contained elements) were used for their characterization. Analytical measurements were performed by mass spectrometry with inductively coupled plasma, allowing the determination of individual nuclides. Different water categories were characterized by chemometrical techniques, mainly by principal component analysis, cluster analysis, linear and quadratic discriminant analyses, correlation analysis, and ANOVA. Their role was to discover the nuclides important for distinct characterization of individual water categories as well as to assess the possibility of water samples from different countries being recognized from the increased/decreased content of some elements. The enhanced content of Cd, Cu, Zn, Bi, and Fe was characteristic for tap water samples, whilst mineral water samples were characterized by the elevated concentration of Sr, Li, B, Ni, Co, As, and Sb. The classification results were successful and close to 100 %, which was proved by the leave-one-out cross-validation procedure.
