affect the quality of water, land, flora and fauna. Proper waste management has the effect of reducing the amount of environmental pollution. For this reason, it is very important for people's awareness to be as high as possible. The control of the parameters affecting the pollution must be regular. The South Morava River, located on the territory of the City of Vranje, is the largest and most significant river in the area, which is of great importance for agriculture. Water testing is carried out in two places. Samples are taken from the village of Mezgai and the village of Mramara. Analyzes of the results obtained after testing the water samples from the South Morava River showed that the water contains certain parameters some in larger quantities and some in smaller quantities. Based on the amount of nutrients present below the limit of detection, it can be said that the water quality is satisfactory and that according to these parameters the water is classified in Class II. The measured values of the investigated physicochemical parameters at the sampling site at Marble (Novo Selo) dominantly correspond to class I except for BOD5 corresponding to V class, HPK, orthophosphates corresponding to IV class, TOC, ammonium ion and iron content corresponding to III class, total nitrogen. total phosphorus, phenolic compounds correspond to class II. At the same location, the measured values of microbiological parameters correspond to class III. Measured values of the investigated physicochemical parameters at the sampling location at Mezgraja village level, with the Railway Bridge, dominantly correspond to class I except for BOD5 corresponding to class V, HPC corresponding to class IV, TOC, phenolic compounds and total nitrogen corresponding to class II, nitrites, orthophosphates, ammonium ion, Class III copper and iron content. At the same location, the measured values of microbiological parameters correspond to Class IV. Based on this, it can be concluded that the water from the South Morava River is of medium quality.
