Abstract
Problem Statement and Purpose. The work is dedicated to a very important ecological issue - assessment of the protection of drinking groundwater in conditions of modem intensive technogenesis on the geological environment The purpose of the article was development an effective complex geo-ecological methodological approach to the assessment of the risk of groundwater pollution. Data Methods. The author's development is based on the use of the results of drilling more than 950 wells and more than 700 chemical analyzes of groundwater in the region, and about 500 measurements of the levels of adjacent target and first interlayer complexes during the 1960-2015 period. Also, environmental information and current data of the neotectonic conditions of the research area were used. A number of general research methods - analysis, synthesis, systematization, classification, modeling, and statistical method were used in process the necessary information in the research area. Interpolation methods and analogies were used in modeling of ecological and hydrogeological factors of groundwater protection. Results. For the first time a rational aggregation of geo-ecological indicators was conducted, it allows determining the degree of groundwater complex protection of the aquifer from pollution of technogenic (surface) and natural (neotectonic) characters. An improved methodological approach allows to determine all possible vertical migratory ways of contaminants to the target aquifer. The approbation of an improved methodological approach to water intakes of the buchak-kaniv aquifer, which is one of the strategically important within Eastern Ukraine, was conducted. It has shown the efficiency, operativeness and simplicity use of this approach. It was determined that the surface pollution is not a predominant factor in the deterioration of water quality of the target aquifer. The neotectonic factor of the chemical composition formation of these waters which is unappreciated now is important too. The conducted researches allow to contribute to the development of complex target systems of ecological security of drinking groundwater of territories, their absence is a strategic problem for the whole Ukraine.
