ABSTRACT:
A process of soil remediation in which an encapsulation solution is introduced into contact with a soil matrix containing chemical contaminants such as polynucleated aromatics in an amount sufficient to form a saturated admixture of the soil matrix and the encapsulation solution, the encapsulation solution being capable of preferentially attracting the chemical contaminants contained in the soil matrix, and containing an effective amount of non-ionic surfactant material and water; and the admixture is admixed for an interval sufficient to permit the chemical contaminants to preferentially dissociate from contact with the soil matrix in favor of association with the encapsulation solution. Once this occurs, the encapsulation solution with associated chemical contaminants can be removed from contact with the soil matrix.
