Abstract
A method for the remediation of soils contaminated with hydrocarbons utilizing a selective liquid additive. The method includes the steps of collecting the contaminated soil; reducing the collected soil to finely-divided particles: applying a controlled amount of the selective liquid additive as a spray onto the contaminated soil particles; and aerating the soil particles as the additive is being applied. After treatment, the decontaminated soil is rendered environmentally safe.
Claims6
A method for remediating soils contaminated by hydrocarbon pollutants comprising the steps of:
- (a) collecting the contaminated soil;
- (b) reducing the collected soil to finely-divided particles;
- (c) applying a controlled amount of a selective liquid additive as a spray onto the contaminated soil particles, said liquid additive consisting essentially of an aqueous solution of sodium silicate, ethylene glycol and sodium methyl silanolate;
- and
- (d) aerating the soil particles as the additive is being applied, whereby the treated soil can be safely discharged into the environment.
