In Situ Remediation of Hazardous Wastes
Abstract: Numerous releases of hazardous substances have occurred at uncontrolled sites all around the United States. These sites pose toxic threats to public health and our environment, and potential loss of natural resources. The traditional approaches of site isolation or excavation and disposal of the contaminated soil or both do not provide a permanent solution. The challenge facing us is to restore the land to an environmentally safe and reusable state with minimal amounts of hazardous wastes to ultimately be disposed. In situ soil remediation offers the attractive alternative of leaving the soil in-place, thereby reducing the amount of hazardous material to be destroyed. We must actively investigate this option and continue to develop the technology to implement it.
