In the present paper were statistically analyzed by PCA method the concentration values of macro and microelements from nine mineral water samples collected in western, central and northern Romania. In case of macro elements multivariate analysis PCA of data from atomic spectroscopy for mineral water samples showed a good classification of samples B and C, data variance is explained 100% of the first three principal components (47% PC1, 49% PC2 şi 4% PC3). For microelements this analysis led to the good group of samples A and B, samples C are irregularly distributed. The variance explained is of almost 100% for the first principal component.
