PUBLIC ENVIRONMENTAL MONITORING OF DRINKING WATER QUALITY IN THE CITY OF NORILSK

Аннотация

According to UN estimates, the shortage of safe drinking water can become one of the most acute
and pressing problems. The specificity of this problem for Russia is not a shortage of water resources, but their
pollution and ongoing degradation of water bodies. The quality of water is understood as the totality of its properties
associated with the nature and concentration of impurities in the water. Water analysis is the only tool for monitoring
its condition and properties. 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, studied the dependence of the quality
characteristics of water on the location and sampling method. Based on the findings, conclusions on the quality of
drinking water were drawn. 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. Having made the necessary analyses, 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
