Analysis of water supply sources in Kormilov district of Omsk region

Abstract

The article describes the sources of water supply inKormilovka district of Omsk region. The main sources of water are surface waters of the Om and Taburga rivers, lakes and artificial reservoirs, groundwater. In general, the territory of Kormilovka district lacks fresh groundwater. Currently, water is supplied by hydraulic structures on the Omriver as part of water intake and treatment facilities, water pipelines and a pressure distribution network. Water supply from underground sources is carried out from tubular wells with a depth of 5.0 - 9.0 m, from wells with a depth of 200 m and deep-water wells of about 1100 m. Water intakes from underground sources are available in almost all rural settlements, but they are used for technical and (or) economic purposes. An ecological assessment of the state of surface and underground sources isprovided. The results of an analysis of the geological and hydrogeological situation are presented. Of greatest interest are Neogene-Quaternary, Upper Oligocene-Lower Miocene and Lower Upper Cretaceous (Pokursky) complexes. According to the generalized characteristics of quality of groundwater from three underground aquifers in Kormilovka district, the most acceptable is the Pokursky aquifer, since itsgroundwaters are less mineralized, softer, more protected, and, consequently, their microbiological and parasitic indicators comply with the sanitary standards. When using both surface and groundwater for household and drinking purposes, it is environmentally safe for the population only after adjusting such indicators as turbidity, color, chlorine, iron, and dry residue content and bringing the microbiological indicators to SanPiN 2.1.4.1074-01 and SanPiN 2.1.4.544-96.
