Ibar River. The paper analyzes the water quality of the Ibar River in May and September 2019, at three selected profiles located at the middle and upper course of the river. The test included 25 parameters of physical, chemical and microbiological water quality. Based on the results of the analysis of physico-chemical and microbiological parameters and their comparison with the legal norms of water quality, all samples were found to exceed the maximum permissible concentration (MPC) for one third of the tested parameters, which is why the water of the Ibar River belongs to the third quality class surface water. By comparing the obtained results of the values of water parameters during both testing periods, it was determined that the water was of a relatively similar quality in terms of the content of pollutants at all three profiles. During the entire research period, the water quality was the best at the Rud-nica profile, and the worst at the Raška and Baljevac profile. Increased concentrations of heavy metals of iron and lead in all water samples tested indicate permanent pollution from the active mining plants and flotation tailings whose wastewaters flow into the Ibar. According to the research results, the values of the SWQI index ranged from 72 to 81 points, which corresponds to the descriptive indicator “good” water, while according to the Bylaw (Official Gazette of the Republic of Serbia No. 50/2012) the water of the Ibar River at all three locations during both sampl...
