The research is relevant due to the need for studying the current condition of underground waters used as water supplies and analyzing the problems related to the change in chemical composition of underground waters caused by operation. These changes depend both on natural landscape and climatic and hydrogeochemical zonality, and on water intake operation mode. The enrichment of underground waters with iron due to regional features of geochemical conditions leads to inevitable application of water treatment which effectiven- ess can be significantly changed under the influence of water selection. The main aim of the research is to estimate the potential impact of hydrodynamic conditions under the influence of long operation of large water intake on the changes in the quality of underground waters of the operated field. Methods. The local monitoring of operating water intake has been conducted for a long period of time for solving operational investi- gation tasks on the operating field of underground waters. The analysis is based on the results of this monitoring. We have generalized observation data on the position of static levels. The materials of a hydrogeochemical approbation were used for studying the changes in chemical composition of underground waters. Such approbations are carried out regularly according to the regulations of regime ob- servations. The overflowing between aquifers is assessed quantitatively by means of numerical hydrodynamic modeling. Results. The analysis of monitoring results has shown that in the course of intensive operation of underground waters the favorable con- ditions for accumulating iron in the dissolved and hard-to-recovered form arise. The formation of complex organomineral iron compo- unds contributes to favourable conditions as such compounds are poorly manageable to removal during standard water treatment on the basis of aeration. We consider the changes in geochemical condition in the filter areas of operational wells to be the main reason for these anthropogenic processes. The changes in geochemical composition are caused by rising acid waters which have high concentration of organic compounds.
