Ostroukh O. The regularities of the changes in the chemical composition of groundwater aquifers of the Chop-Mukachivskyi basin

Dissertation is devoted to research of spatio-temporal changes of hydrochemical terms of groundwater aquifers of the Chop-Mukachivskyi basin, which are exploited by numerous water intakes and mining holes and widely used for the drinkable water-supply of population, industrial and agricultural objects.In dissertation the author has accomplished investigations concerned with research of factors of forming the chemical composition of waters in this basin. The author has exposed and appraised spatio-temporal regularities of changes of chemical composition of waters with the using of statistical analysis, cartographic modelling and GIS spatial analysis. In consequence of study the environmental conditions of groundwater aquifers protection by the author's improved method, the categories of protection of groundwater aquifers are selected. The complex analysis of the estimation of the modern hydrogeochemical conditions of groundwater aquifers of the Chop-Mukachivskyi basin are conducted.South-eastern and western part of the Chop-Mukachivskyi basin, belonging to unprotected groundwater aquifers, is characterized by changes in mineralization and hardness of water. In the northern part of this basin, where aquiclude has considerable thickness and groundwater aquifers are charted as apparent protected, the changes of mineralization and water hardness has not happened. The comprehensive approach to the estimation of the modern hydrogeochemical conditions groundwater aquifers has established the areas without the noticeable rejections of chemical composition of groundwater aquifers (belong to apparent protected) and areas with the considerable alterations of chemical composition, which are belonging to unprotected groundwater aquifers.
