The selected remedy, soil mixing using in situ chemical oxidation (ISCO) combined with in situ solidification and stabilization (ISS) was used to destroy contaminants while stabilizing soils
ISCO was successfully combined with ISS at this site achieving all of the remedial goals common for redevelopment sites. Benzene and TPH (C4 to C12) were reduced to below the remedial goals. TPH (C13 to C40) were reduced and the residual contamination was then solidified into a matrix with a significantly lower permeability compared to the surrounding geology. Finally, the soils had targeted compressive strengths shortly after the application allowing for site activities during the application and rapid site redevelopment.
