The purpose of this study was to determine the quality of water in lake Batllava, through which, a part of the population of the Pristina region is supplied with drinkable water. Lake Batlava is a lake built in the 1970s. This lake is located in the village of Batlava in the municipality of Podujeva. The supply of this lake with water is made from the Brvenica river. Monitoring was finished during the period from December 2020 to May 2021. The sample were taken in three championic places: at the entrance of the lake, in the middle and in the spill, on two levels, in the surface and at depth of 30 cm. The analyzed microbiological parameters are: total coliforms, fecal coliforms, fecal streptococci and aerobic mesophilic bacteria. The physical-chemical parameters are: dissolved oxygen, saturation with O2, water temperature, pH value, electrical conductivity, total soluble matter, total suspended matter, turbidity, chemical demand for oxygen, biochemical demand for oxygen, total organic carbon, nitrate, total solidity of calcium, magnesium, ammonia ion, chloride, sulphates, fluurite, M-alkalines, bicarbonates and heavy metals, such as: Fe, Pb, Mn, Cu, Cd. The results showed that most physical-chemical and microbiological parameters are within the limit allowed by the WHO and EPA, except in some cases where during the precipitation season there have been several overruns and for this reason, it is recommended to take monthly monitoring of the water of Lake Batllava to achieve a real assessment.
