  • Ecological assessment of groundwater quality Kuibyshev district, Rostov region and methods of treatment

    The problems of drinking water supply of Russian population in rural areas, where the level of life support is lower than in urban areas are not just escalated but become depopulation factor in some regions. While developing and recommending any water treatment technology first of all it is necessary to be guided by the chemical composition of source water. In many rural areas groundwater has become the only source of drinking water, because the level of surface water contamination and hydrometric characteristics make them unsuitable for use. The data for the survey of physical and chemical composition of groundwater and groundwater from wells and public wells used in the drinking water supply of Kuibyshev district in Rostov region are delivered. The analysis showed that Kuibyshev region belongs to the areas of virtual absence in fresh groundwater resources, where groundwater with increased salinity and high content of sulfates and hardness are prevailed .The ecological assessment of using this water desalination method as reverse osmosis was carried out in this study. In areas with no centralized sewerage and sewage treatment facilities, the Kuibyshev region belongs to, using of this method is inappropriate.

    Keywords: rural settlement, underground water, drinking water, salinity, hardness, purification, reverse osmosis, soil salinization.
