microbiological indicators

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 article presents the results of the analysis of surface water quality indicators changes in water bodies near settlements in the Mykolaiv region in the areas that were flooded after the destruction of the Kakhovka HPP. The analysis of critical water quality monitoring data on sanitary, chemical and microbiological indicators revealed a deterioration in water quality in the Dnipro-Bug Estuary and the Ingul, Ingulets and  Southern Bug rivers.

The microbiological parameters of surface water as indicators of the ecological state of the Carpathians in Pokuttia-Bukovina region were studied. The water streams of the National Nature Park "Vyzhnytskyi", where a specific ecosystem has been formed for more than two decades, were used as a standard for comparison. The possibility of using "biofilters" based on a synthetic carrier "Viia" for purification of natural water streams and raising the level of ecological safety of mountain ecosystems has been proved.
