Today, environmental water degradation all over the world comes about due to the growth of urban, industrial and agricultural activities. As a result of these discharges without any prior treatment, the quality of river waters in Kosovo has deteriorated greatly. On the basis of the research that has been done so far in the rivers of Kosovo, it was shown that Drenica is one of the rivers that are constantly exposed to the discharge of industrial waters. Therefore, the purpose of this research was to analyze the impact of water discharged from Feronikeli on the water quality of the Drenica River and the possibility of its protection. The realization of this study is focused on the evaluation of physico-chemical parameters of the water of the Drenica River, the content of heavy metals in the water, the analysis and comparison of the results obtained using the standard for the assessment of the ecological status of surface waters of Romania (GD 161). Laboratory assays were developed according to standard analysis methods (APHA). The results obtained, analyzed and compared with the values of the parameters according to the standard referred to in this research, confirm that the water of the Drenica River belongs to the class of water with “good quality” only in the source area, while in other flow stations river, especially in the third station S3 (Ferronikel industrial zone), water has “poor quality”, passing into the category of “very poor quality”. Therefore, in order to improve the current situation, it is recommended to apply the best environmental practices and proper management of industrial waste.

The major impacts on aquatic ecosystems worldwide caused by land use lead to changes in their natural conditions and limitation of water use for various needs. This paper presents the results of the study of the physical and chemical parameters and macroinvertebrate assemblage in the White Drin River (or: the Drim River, Alb. the Drini i Bardhë River) basin, the largest in Kosovo. Macroinvertebrate sampled at 11 sites in the river resulted in 5946 collected benthic organisms, which in taxonomic terms belong to 12 orders and 51 families. Of the total number of organisms, 72.28% were Insects, 25.39% Amphipoda crustaceans and 2.33% were Annelide worms and Mollusk. The used biotic indices Biological Monitoring Working Party (BMWP), Ephemeroptera, Plecoptera, and Trichoptera (EPT), average score per taxon (ASPT) and Stroud Water Research Center (SWRC) classify water quality in excellent category in the sampling site S1 near the source of the White Drin River, whereas in other sampling sites, as a result of pollution, water quality varies on category II–IV. The Pearson's correlation analyses shown that the physical and chemical parameters affect the water quality and the composition of macroinvertebrates. Our results show that the parameters that adversely affect the BMWP, EPT and ASPT biotic indices as well as the Shannon–Wiener, Mergalef and Menhinik diversity indices are: pH, electrical conductivity (EC), total suspended solids (TSS), nitrates (NO3–) and chlorides (Cl–). We can conclude that the anthropogenic impact on White Drin basin affects the physical, chemical and biological parameters of the water therefore these parameters should be constantly included in Biomonitoring and Management plans for water resources in Kosovo.
