Abstract:

Generalization of data on the geochemical status and content of standard substances in natural water sources of the centralized drinking water supply systems in Tyumen and underground sources of decentralized drinking water supply was carried out. Data from the environmental monitoring of the following water bodies were used: surface water of the Tura River above and below the city of Tyumen, groundwater of Velizhansky field. A quantitative chemical analysis and express analysis of water samples from municipal water systems and ground water samples from wells and boreholes in the vicinity of the city of Tyumen on chemicals of allowable concentration, normalized by sanitary rules, were held. On the basis of these studies we identified indicators of the quality of natural and tap water and its compliance with hygiene requirements. Surface waters of the Tura in the spring and summer of 2014 are polluted with manganese, ammonium nitrogen, and petroleum products. The critical indicator of pollution is the manganese pollution. The groundwater is characterized by a high level of total iron and manganese, increased level of silicon, ammonium nitrogen, and organic compounds. The well water has a high concentration of nitrates. The tap water has the level of iron, manganese, and permanganate oxygen demand, higher than the maximum permissible concentration. The correlation between the content of components in the groundwater, subsurface water, and tap water has been established.
