A Numerical Model Study of Chemical Pollution Migration in Groundwater Near Industrial Waste Storages Located in River Valleys

The paper deals with the use of the "memory effect" of a groundwater aquifer for the retrospective estimation of the sources of groundwater industrial pollution, and in order to obtain a reliable estimate of their impact on groundwater and surface water. It is shown that combination of the mathematical modelling with the analysis of the age of underground waters during the calibration of the geomigration model makes it possible to significantly refine the parameters of pollution sources, obtain reliable modern aureoles of groundwater contamination, and thereby increase the reliability of predictive calculations
