Chemometrics analysis of groundwater quality data around municipal landfill and their potential influence on population's health
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 have occurred over a long period of time. The results have shown that the concentrations of the most measured parameters (NO3-N, NH4-N, oil, organic matter Fe, Pb, Ni and Cr) were above allowed limits for drinking and domestic purposes. Conclusion This study has provided important information on ecological status of the groundwater systems and for identification of groundwater quality parameters with concentrations above allowable limits for human consumption. The results generally revealed that groundwater assessed in this study mainly does not satisfy safe limits for drinking water and domestic use. As a consequence, contaminated groundwater becomes a large hygienic and toxicological problem, since it considerably impedes groundwater utilization. Even though, all of these contaminants have not yet reached toxic levels, they still represent long term risk for health of the population.
