Public Environmental Monitoring of Drinking Water Quality in the City of Norilsk

The Aim of the paper is the analysis of water – the only tool for monitoring its condition and properties. 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 (NIR) (without preliminary draining and after 5 minutes of draining), studied the dependence of the quality characteristics of water on the location and sampling method. Findings of this study are clearly demonstrated the quality of water in Norilsk. During the experiment, the authors found that in terms of organoleptic indicators, drinking water in all areas of the NIR meets the requirements of Sanitary Rules and Regulations and GOST. Taking samples at three control points of the Norilsk industrial region, it has been proven that the water is soft and its salt content is mainly due to the presence of hardness salts. In conclusion, the authors found that the presence of microorganisms in the water supply network of the NIR is not significant, the permanganate oxidisability indicator does not exceed the requirements of Sanitary Rules and Regulations.
