Investigation of the concentration of heavy metals in the drinking fountains of the mountain massif Shale and Bajgore in Kosovo
Taking in consideration that drinking water is a vital element without which the normal existence of humans and other living things in our planet cannot be thought of, we are motivated to research the wells and springs used for drinking in the villages of Bajgora, Kovacica and Kaqandoll. The suspicion that the waters of this mountain massif contain heavy metals due to the presence of mineral ores also prompted us to investigate the degree of presence or not of heavy metals in these waters. To assess the water quality of these wells, in the monitoring network that includes these three villages, we have pinpointed five monitoring points, determining the organoleptic, physic-chemical, and microbiological and heavy metal parameters. During the research process, in order to evaluate the water quality as accurately as possible, classical and instrumental methods of chemical analysis were applied. We have compared the results of the analysis with the standard values of AI16 / 2012- Administrative Instruction of Kosovo that has to do with the quality of water for human consumption and that is in full compliance with EU Directive 98/83 EC. The obtained results denote the presence with heavy metals of Pb, Zn, Cd and Ni, in four of the five samples taken for research. Therefore, we have come to the conclusion that the presence of these metals results as a consequence of the geological composition and ore-rich underground layers of this mountain massif.
