Formation of hydrogeochemical barriers in the contact areas of technogenic groundwater flows with the surface of natural waters

The paper discusses the processes of heavy metals accumulation in the zone of constant contact. Distribution of metal concentrations in water and bottom ground of the study area has been studied. Water samples (bottom layer) and sediment samples taken in the mixing zone have been studied. It has been shown that in the mixing zone at a hidden underground discharge of groundwater runoff by bottom sediments acts as a filter for heavy metals, a hydrogeochemical barrier is formed. The barrier parameters (thickness, gradient and contrast) for each of the investigated elements in the bottom layer of water and the bottom ground have been studied.
