Quality Assessment of Supply Water of Gjakova City (Kosovo): A Case Study of Correlation Coefficients between Chemical Data

Summary/Abstract: In this study the quality assessment of supply water of Gjakova in the period time January to October was investigated. Statistical studies have been carried out by calculating of basic statistical parameters, anomalies and correlation coefficients between different pairs of variables. From the results of field work and laboratory analyses it was found out that supply water of Gjakova fulfill the criteria set by the World Health Organization and the low distribution of physico-chemical parameters indicated  lithological pollutions. The statistical regression analysis has been found a moderately high positive correlation relationship between pH and EC, consumption of KMnO4, Turbidity, Cl-, Al3+ and NO3-. Result dates suggest also strong positive correlations of EC with Turbidity, consumption of KMnO4, Cl-, Al3+ and NO3-. R-mode cluster analysis showed mutual links between studied parameters. It could be observed on water samples that EC has closest linkages with consumption of KMnO4 and they form first branch of the dendogram. Also EC has closest linkages with NO3- and they form second branch of the dendogram.
