Groundwater as a source of water supply for the Krutinsky District of the Omsk Region

Abstract

The paper presents the results of the analysis of geological and hydro-geological situation in the Krutinsky district of the Omsk region, as well as the assessment of the quality of groundwater in terms of environmental friendliness of their use for potable water supply. In hydro-geological terms, the research area is located within the Irtysh artesian basin, covering a vast territory in the south of the West Siberian lowland. The Cenozoic sediments that compose the described territory contain a number of underground reservoirs, horizons and water-resistant strata separating them. The waters of Quaternary, Neogene and Oligocene sediments are of practical importance as a source of water supply. Groundwater is exploited by wells and shallow waters (in Neogene and Quaternary sediments) are exposed and exploited by many shaft wells. The article provides a generalized characteristic of the quality of underground waters of Quaternary, Neogene and Paleogene deposits, as well as production wells drilled in the Krutinsky district of the Omsk region. As a result of research, it was found that groundwater does not meet the requirements of SanPiN 2.1.4.1074-01. The use of these waters for household and drinking purposes will be environmentally safe for the population only if such indicators as turbidity, color, chlorine, iron, dry residue and microbiological indicators are adjusted.
