Polymer gel barrier containing microorganisms for containment of hazardous waste

摘要

A method of containing and remediating contaminants within the soil includes the step of placing a gel barrier into the soil for containing the contaminants. The gel barrier and the soil contained therein define the containment zone. Microorganisms capable of remediating the contaminants in the soil are added to the containment zone. The gel barrier is produced by preparing an aqueous solution of a gel precursor, injecting the aqueous solution into the soil at a desired location, and crosslinking in situ the gel precursor to form the gel barrier at the desired location.
