Abstract

This article contains the results of research related to the groundwater quality deterioration issue in the northern part of the Crimean Peninsula under intense usage conditions. The most trustworthy forecasts for changing hydrogeochemical conditions in the further groundwater extraction can be based on geo-migration models, the creation of which requires much information about aquifers, which is not available. This paper aims to analyze hydrodynamic and hydrogeochemical conditions of the explored territory to validate the geo-migration model with insufficient benchmark data. To achieve the goal, the spatial-temporal mapping of the hydrogeological conditions on the explored territory has been carried out, as well as piezometric maps have been created and analyzed; and analytical hydrodynamic calculations have been made. The results show that groundwater quality deterioration is connected mainly with hydrogeological regularities of the region. Irregular changes in the groundwater composition are caused by hydrogeochemical and hydrodynamic heterogeneity of aquifer systems. Based on the analytical calculations and further correlation of results with observations and hydrogeological composition, necessary information for creating geo-migration model has been obtained, and further change to groundwater quality has been projected.
