According to the annual monitoring of water bodies in the Tyumen Oblast, it can be concluded that more than half of the samples taken from drinking water supply sources according to sanitary and toxicological criteria did not meet the normative values out of the total number of 54.3% taken in 2018. Compared to 2016, this indicator has increased by 7.1%. The dynamics of increasing pollution of water bodies is confirmed by the fact that in 2015 the quality of surface sources of drinking and domestic water supply did not meet the standards of 20.6% of the analyzed samples, which is 1.4% higher than in 2014. The current situation is partly explained by flood phenomena accompanied by surface runoff contamination of the water area, partly by peculiarities of hydrological and hydrochemical nature, partly by anthropogenic activities: operation of existing enterprises and commissioning of a number of industrial facilities: Tyumen Waste Incineration Plant, Antipinsky Oil Refinery, etc. It was noted that iron, silicon and ammonia in surface water sources exceeded MAC up to 5 times.
