An important issue in Kosovo is water pollution. The use of polluted water has a direct impact on human health and cause long-term consequences. The longest and most polluted river in Kosovo is the Sitnica, a 90 km long river with its source located near the village of Sazli. The river flows into the Ibar River in Northern Kosovo. Agriculture is prevailing activity in the basin of Sitnica which is why agricultural as well as industrial waste are the biggest water pollutants. The purpose of this study was to evaluate water quality of the river and analyse the pollution level along the Sitnica River caused by agricultural activities and industrial discharges. In order to assess the impact of pollutants on this river, a measurements were carried out in four (five) monitoring stations: the first station represents the reference station which has not undergone or has not been affected by polluting pressures, two stations in water areas affected by the irrigation of farming land and two monitoring stations in water areas affected by industrial wastewater discharge. Some of the parameters of water quality analysed are temperature, turbidity, electrical conductivity, pH, DO, COD, BOD, P total, nitrates, sulfates, and heavy metals iron, manganese, zinc, nickel. Compared to the reference station the results obtained from the Gracka and Pestova monitoring stations prove that the dominant form of pollution is that from agricultural lands irrigation, while the Plemetin and Mitrovica stations show that the Sitnica River is affected by wastewater discharge which contains significant concentrations of heavy metals, as well as metal ions selected in this paper. It can be concluded that the irrigation of agricultural lands and discharges from mining significantly affect water quality of the Sitnica River.
