ABSTRACT:
A process for the remediation of soil containing volatile organic compounds which comprises the steps of: (1) forming an emulsifier comprising: (a) from about 70 to about 99% by weight of a sugar surfactant selected from the group consisting of an alkyl polyglycoside, a glucamide, and mixtures thereof; and (b) from about 1 to about 30% by weight of a nonionic surfactant, other than said sugar surfactant which, when combined with said sugar surfactant, provides a hydrophilic-lipophilic balance of from about 8.0 to about 13.0; (2) mixing said emulsifier with said unwanted contaminants to form a stable emulsion; and (3) removing said stable emulsion from said soil.
