The following research work is devoted to the study of the water quality of the Tupolang reservoir and the possibility of its use for the centralized drinking water supply of the population. Studies of the dynamics of changes in the water quality of a water body were carried out according to the established observation stations for different seasons of 2018. It has been established that the water quality of a water body does not meet the requirements of GOST 951: 2011 “Sources of centralized drinking water supply. Hygienic, technical requirements and selection rules”. The dynamics of changes in microbiological indicators is characterized by a maximum increase in the total microbial number (TBC) of the water of the reservoir in the summer season of the year and the mismatch of the number of bacteria of the group of intestinal sticks (HBOC) in the water to hygienic standards. The highest concentrations of turbidity in the reservoir (up to 6.6 MPC) are set at the site before the dam in the winter season, and the lowest (up to 1.2 MAC) in the spring season. Heavy metals in the water of the Tupolang reservoir are detected at the level of background values. However, the aluminum is found in water (the lower part of the reservoir) in concentrations exceeding the established MPC. Organoleptic characteristics of water in intensity of smell, color and pH meet the requirements. Concentrations of magnesium in the water of the reservoir, depending on the area of the reservoir, exceed the MPC 1.3-1.7 times in the winter season of the year. Fluorine in the water of the Tupolang reservoir is present in quantities that are 3.9-7.0 times lower than normal. To use the Tupolang reservoirs for drinking needs by the population, the purification water from microbial and chemical contamination and mandatory water fluoridation are necessary.
