In the present paper were statistically analyzed by PCA method the concentration values of anions and cations from nine mineral water samples collected from western, central and northern Romania. In case of principal component analysis using anion concentration data present in mineral waters not found a clear grouping of samples, which is distributed relatively evenly scoring chart. In case of PCA analysis for the cation concentration data obtain a good group of samples B and C, the explained variance of the data of 54%, 41% and 4% for the first three principal components.
