Features of the formation of operational groundwater reserves of crystalline rocks in the area of the city of Nemyriv, Ukraine

Abstract

The results of studies of the formation of operational groundwater reserves in fractured crystalline rocks of the Nemyrivs’ke deposit using mathematical modeling are presented. The choice of this research method is due to the fact that water availability is determined by the nature and degree of rock fracturing. The purpose of the work was to determine the potential opportunities for providing the population of the city of Nemyriv with reliably protected drinking groundwater, including through additional exploration and development of prospective areas identified according to geophysical data. Using the modern hydrogeological model created for the first time, based on the results of solving inverse problems, the hydrogeological parameters of the water exchange system were specified, and the functional correspondence of the created model to natural and anthropogenic conditions was proved. A predictive assessment of operational reserves of drinking groundwater has been carried out and the potential for their possible increase has been shown. The influence of predictive water withdrawal on the environment is assessed and issues related to the quality of drinking groundwaters are considered. The last of the above is very important, based on a certain ecological problem associated with the infiltration of polluted water from ponds on the left bank of the Ustya River, as well as city wastewater discharged into the bypass canal in the area of sanatorium “Avangard”. As a result, the authors recommend conducting groundwater exploration in promising areas upstream of the Ustya River from the city of Nemirov (Nemyrivs’ka and Mukhovets’ka), as well as in the valley of the Pivdennyi Buh River (Buz’ka, Sheludkivs’ka).
