ABSTRACT:
A system for preventing upward migration of contaminants in soil having capillary pores defined therein, the system comprising the soil and a hydrophobic substance applied to the soil, the substance being attracted to enter the capillary pores so that a barrier is formed which, under unsaturated soil conditions, prevents the upward migration of contaminants carried by water through the capillary pores in the soil.
