Groundwater pollution has been an issue of concern for environmentalists, since the pollution could be hardly reformed. The heavy metal analyses of Cu, Pb, Mn, Zn, Ni, Cr and Fe were performed for the water samples. This study presents the application of some selected multivariate statistical techniques and confirmatory analysis to identify the sources of heavy metals in the groundwater in the Stan Terg, Kosovo. Correlation analysis showed that the mean concentration of heavy metals (Cu, Pb, Mn, Zn, Ni, Cr and Fe) in the water springs samples were positive correlated values. Principal cluster analysis and factor analysis investigated the origin of the water quality parameters as due to various mining activities: three principal components were obtained with 92.697% total variance. The results of heavy metals analysis indicated that groundwater is pollution in the Stan Terg. Overall, the results showed that the groundwaters of the Stan Terg in North Kosovo are contaminated with heavy metals, which might affect human health as well as the health of the ecosystem.
