ABSTRACT:
An in situ method of reducing concentrations of contaminates in contaminated soil, where contaminated soil positioned in a first horizontal location is in situ mixed with clean soil in vertical proximity to the contaminated soil. The mixed soil is blended under conditions and for a time sufficient to substantially homogenize the contaminants in the blended soil. The mixing and blending is then repeated for a second horizontal location.
