The specificity of this problem for Russia is not a shortage of water resources, but their<br>pollution and ongoing degradation of water bodies. The quality of water is understood as the totality of its properties<br>associated with the nature and concentration of impurities in the water. Water analysis is the only tool for monitoring<br>its condition and properties. During the experiment, a team of researchers took samples of drinking water from the<br>water supply network in various districts of the Norilsk industrial region, studied the dependence of the quality<br>characteristics of water on the location and sampling method. Based on the findings, conclusions on the quality of<br>drinking water were drawn. During the experiment, the authors found that in terms of organoleptic indicators,<br>drinking water in all areas of the NIR meets the requirements of Sanitary Rules and Regulations and GOST. Taking<br>samples at three control points of the Norilsk industrial region, it has been proven that the water is soft and its salt<br>content is mainly due to the presence of hardness salts. Having made the necessary analyses, the authors found that<br>the presence of microorganisms in the water supply network of the NIR is not significant, the permanganate<br>oxidisability indicator does not exceed the requirements of Sanitary Rules and Regulations</p> ER -
