Abstract: The provision of quality drinking water is one of the most important conditions for public health, especially in urban areas. Like many other settlements, the city of Mykolaiv faces problems with the quality of water supplied to consumers. This study evaluated some bacteriological parameters of drinking water supplied from different sources in the city and conducted a comparative analysis of the effectiveness of using plant coagulants for disinfection. Water samples were collected from underground sources, artesian wells, the municipal water supply network, and the Bug Estuary. The study was carried out regarding total microbial counts, coliforms, Escherichia coli, and enterococci. The results showed the presence of bacterial contamination in some samples; in particular, E. coli was detected, indicating fecal contamination of the water. Some of the samples treated by reverse osmosis met sanitary standards. The results emphasize the need to strengthen control over drinking water quality and introduce effective post-treatment technologies. The proposed use of natural coagulants is a promising alternative to traditional chemical treatment methods and can help improve the environmental safety of the water supply.
