A method and system of storing and containing existing toxic waste dump sites, to prevent leakage and seepage from the waste site. It involves ascertaining the soil characteristics to determine the moisture impervious layer depth for the soil surrounding the pit site, digging a perimeter trench around the dump site to a depth at least equal to the moisture impervious layer, filling the perimeter trench with a substantially moisture impervious material, placing a well casing within the area defined by the perimeter trench, adjacent to the pit, and placing a drain line below the bottom of the toxic waste site dump pit in fluid communication with the well casing. As a result of this alteration of the water drainage profile within the surrounding soil, the risk of seepage, leakage and drainage of toxic waste into the aquifers is lessened.
