Suspicions of diverse pollution of groundwater in the villages of Dremjak, Talinoc i Muhaxherve, Softaj, Gërlicë and Varosh of the Ferizaj municipality motivated the investigation of empirical quality of the water wells from which the inhabitants of the villages provided drinking water. Considering that drinking water is the basic element for humans to live, its testing prior to consumption is necessary, therefore, this groundwater is the focus of this research. The samples were taken from the pumping stations, where underground waters were collected. The water was tested for organoleptic, physicochemical, and microbiological parameters, and during the analysis the classical analytical and instrumental methods were applied. The results of the analyses were compared with the Administrative Directive No. 16/2012 of Kosovo and the Instruction No. 98/83 of the EU, based on the standard values of the water quality consumed by humans. Both are in line with the standards of the World Health Organization for drinking water quality. It was determined that the groundwater in the respective five villages was contaminated with heavy metals (Fe, Pb, Mn, Cd and Ni). The water samples taken for analysis based on the underground map of the region show that the underground layers contain metals to some extent. Therefore, the presence of such metals in water is due to geological pollution. However, other organoleptic, physico-chemical and microbiological parameters are compatible with reference values.
