At present, the problem of the availability of high-quality fresh water is urgent. The reservoirs from which water is extracted are running low. The amount of fresh water on the planet has decreased significantly in recent years. A big problem for the use of fresh water is its pollution. Groundwater remained relatively clean, but even when used, it needs to be controlled. Goal of research was the quality control of water from ponds and water sources in the National Dendrological Park (NDP) "Sofiyivka" of the National Academy of Sciences (NAS) of Ukraine in terms of physicochemical and bacteriological indicators and a study of the park's hydrosystem. When conducting research, potentiometric, gravimetric, titrimetric, colorimetric and spectrophotometric methods were used. The hydrosystem of the NDP "Sofiyivka" of the NAS of Ukraine, created during the period of its foundation, has basically retained its planning forms and all its artificial structures. The water system is an important environmental factor that contributes to the quality development of plants, and also has an aesthetic value. The analysis of the results of a study of the physicochemical and bacteriological composition of drinking water from the studied water catchments showed that the water is safe for consumption in terms of such indicators as the content of sulfates, nitrites, chlorides, but contains a significant amount of nitrates and has a high hardness, which can contribute to the development of a number of diseases. Long-term consumption of such water will have a negative impact on the human body. In all water samples from the capture, the growth of common coliforms in 100 cm3 and the presence of Escherichia coli were found, which is dangerous when drinking unboiled water and can bring to intestinal infectious diseases. According to the obtained experimental results of the quality of the studied water samples from the Krasnostavsky, Upper and Lower ponds of the NDP "Sofiyivka" NAS of Ukraine, the general physical and chemical indicators fully comply with the established standards, but the results of studies of the ponds in terms of bacteriological indicators, namely the index of lactose-positive E. coli indicate their significant excess and non-compliance with the standards in the Krasnostavsky and Verkhny ponds by 48 and 12 times, respectively.
