METHOD OF IN SITU BLENDING OF SOIL TO REDUCE CONCENTRATION OF TOXIC RESIDUE IN THE SOIL

摘要

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.
