The South Morava River is very important for the City of Vranje because it serves for irrigation of agricultural land, so its water quality is of great importance. Water quality control in the South Morava is done on a monthly basis by chemical and physical methods. Controlling is done at two measuring points from which the samples are taken, namely the village of Mezgraje, near the Railway Bridge, and the site of Marble Novo Selo. Tests of water samples from the South Morava River included determination of: general parameters, nutrients, salinity, organic substances and microbiological parameters. 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. The South Morava from the physico-chemical aspect has a mixed excellent to poor ecological status, while from a microbiological point of view it has a moderate ecological status at Mramor (Novo Selo) or poor ecological status at the level of the village of Mezgraja, at the Railway Bridge. The results of the water quality control tests show that the water is nutrient-poor and has microbiological parameters present in MPN / 100 ml.
