Evaluation of Physico-chemical Parameters of the Lumëbardhi of Deçani River and Radoniqi Lake, Kosova

Rivers and lakes are the most valuable natural resources for human beings. Unfortunately despite of its importance, fresh water resources are being polluted by disposable of sewerage, industrial effluents, municipal waste, mining activity, agricultural activity and other different types of waste into the river/lakes. The objective of this study was to assess physico-chemical parameters of the Lumëbardhi of Deçani River as a main water supplier of Radoniqi Lake during the year, 20015. The variations of water quality parameters along the river courses (upper, middle and lower course), between seasons and in lake were examined. The majority of the parameters showed that there is significant variations of the water quality parameters between the winter and summer seasons. However, the variations along the river courses sampling site (upper, middle and lower course) were higher at the middle sampling site in urban areas. This implies that the water quality is influenced more by anthropogenic impacts in the middle course of the river. The physicochemical parameters analyzed in Radoniqi Lake lie within the permissible range and it is a good quality for drinking after treatment, irrigation and fish culture purposes.
