Abstract
It is shown that insulation of masout soil pollution with a bulk layer of pure sand may cause its contamination. The migration of the pollutant against the force of gravity occurs through the mechanism of capillary rise in the case of low moisture content in the pore space, and in water–saturated horizons this occurs also due to the difference in the densities of masout and water.
