| Popis: | Aim To assess the level of 15 groundwater quality parameters in groundwater samples collected around municipal landfill and paper factory in order to evaluate usefulness of the groundwater and its possible implication on the human health. Methods Obtained data have been analyzed by principal component analysis (PCA) technique, in order to differentiate the groundwater samples on the basis of their compositional differences and origin. Results Wastes and effluents from municipal landfill did not contribute significantly to the pollution of the aquatic medium. Groundwater degradation caused by high contents of nitrate, mineral oils, organic and inorganic matters was particularly expressed in the narrow area of the city centre, near the paper factory and most likely it has occurred over a long period of time. The results have shown that the concentrations of the most measured parameters(NO3-N, NH4-N, oils, organic matter, Fe, Pb, Ni and Cr) were above llowed limits for drinking and domestic purposes. onclusion This study has provided important information on cological status of the groundwater systems and for identification f groundwater quality parameters with concentrations above llowable limits for human consumption. The results generally evealed that groundwater assessed in this study mainly does not atisfy safe limits for drinking water and domestic use. As a consequence, ontaminated groundwater becomes a large hygienic nd toxicological problem, since it considerably impedes groundwater tilization. Even though, all of these contaminants havenot yet reached toxic levels, they still represent long term risk for ealth of the population. |
