WATER QUALITY ASSESSMENT OF UNDERGROUND SOURCES OF WATER SUPPLY OF THE RIVNE REGION

English abstract

The state of water resources and water supply of the population of Ukraine remains one of the major pressing threats to the national security of Ukraine in the ecological sphere, which in the conditions of economic and political transformation, military conflict and in the conditions of moisture redistribution acquires new aspects and acuteness. The issue of adaptation of water management in the face of climate change is of particular relevance. The territory of Ukraine is provided with irregular water resources and some regions are extremely affected by the scarcity of this resource. Artesian waters of Ukraine are often characterized by high concentrations of iron – in about 50% of underground water intakes there is a high concentration of iron. And that number tends to increase. Excessive concentrations of iron give the water a brownish color, an unpleasant metallic taste, causes overgrown water pipes and fittings. In small towns, groundwater and artesian water are used. Groundwater is extracted from wells and shallow wells, mostly up to 40-50 m. They often contain pesticides and herbicides, heavy metal ions, surfactants and other dangerous substances. The water quality in the wells of Rivne region differs in physicochemical parameters and depends significantly on the rocks that surround the aquifer. For water treatment of groundwater use non-reagent, reagent, cationexchange, biochemical methods. Each has its own peculiarities of use. It is most expedient and economically advantageous to apply nonreagent aeration methods of water desalination with simultaneous degassing of dissolved gases and filtration through fast filters. During 2013-2017 water samples were taken and studies of the physicochemical composition of natural water from wells in Rivne region were conducted. The composition of water varied in a number of indicators, in particular the content of iron, hydrogen sulfide and dissolved carbon dioxide. The quality of artesian water from wells located in different settlements of Rivne region is analyzed; the trends of the qualitative state of underground artesian horizons are outlined; recommendations for water treatment of iron-containing water are substantiated. The physicochemical composition of water from underground horizons of different settlements of Rivne region is given.
