The influence of anthropogenic load within the Kyiv field of drinking groundwater has resulted in deformation of the water exchange structure and pattern. The main anthropogenic factors affecting water exchange include groundwater intake structures, reservoirs, as well as urban-industrial agglomerations. The paper presents a critical analysis of the previous hydrogeological models of the groundwater field under study, taking into account their shortcomings and using the most realistic solutions. New up-to-date hydrogeological model of the study area has been created. Simulation modelling was performed to determine the effects of hydrogeological parameters changes on the groundwater level position. Epignostic modelling allowed us to specify transmissivity of aquifers, specific permeability of confining beds and natural groundwater recharge, as well as to prove functional correspondence of the created model to naturalanthropogenic conditions. Exploitable reserves of drinking groundwater for the city of Kyiv were reassessed according to the current request of PJSC “AK” Kyivodokanal” and the potential of groundwater withdrawal was shown. Reserves calculated by method of mathematical modelling were approved by the State Committee of Reserves of Ukraine.
