Analysis of drinking water quality in the area of Osijek-Baranja County

Industrialization and the increase of the human population lead to drinking water pollution, and climate change is significantly affecting the availability and quality of water. Drinking water quality has to be checked daily [1]. To test the health safety of drinking water in Osijek-Baranja County, water samples were collected from 6 locations and the following parameters were analyzed: aerobic mesophilic bacteria incubated at 36 ° C and 22 ° C, Escherichia coli, free chlorine, temperature, pH, turbidity, and color [2, 3]. The study was conducted during the winter and summer of 2019 allowing assessment of the water quality depending on the period of the year. Locations near and far from raw water treatment plant were selected to determine the possibility of poor water quality at more distant locations. The results indicate the health safety of drinking water in the tested area, but a slight deterioration of water quality was observed during the summer period. Given the distance from the raw water treatment plant, a significant difference in concentration of free chlorine was found which poses a higher risk for the development of bacteria in the water at more distant locations.
