Aims: Water quality is understood as the totality of its properties due to the nature and concentration of impurities in the water. Providing quality drinking water to citizens has become one of the most significant social problems and the most important factor of national security. The purpose of this study was to analyze the quality of drinking water in the city of Norilsk. Materials & Methods: During the experiment, a team of researchers took samples of drinking water from the water supply network in various districts of the Norilsk industrial region (without preliminary draining and after ۵ minutes of draining) and studied the dependence of the quality characteristics of water on the location and sampling method. Findings: In terms of organoleptic indicators, drinking water in all Norilsk industrial region areas complies with the requirements of Sanitary Rules and Regulations and GOST. Sampling from three control points in the Norilsk industrial region showed that the water is soft, and its salt content is mainly due to hardness salts. Conclusion: The presence of microorganisms in the water supply network of the Norilsk industrial region is not significant, and the permanganate oxidizability indicator does not exceed the requirements of Sanitary Rules and Regulations.
