In Situ Aerobic Cometabolism Followed by Reductive Dechlorination of Trichloroethene to Enable Brownfield Redevelopment

摘要

A major retail development company owns a 30-acre property in northern New Jersey that was historically operated as an aircraft engine parts testing and warehousing facility. After years of operating the property for warehousing, they embarked on an aggressive site-wide retail redevelopment to enhance the utilization of the property. During investigation of the property by prospective retail tenants, it was determined that soil and groundwater at the site were impacted by historic discharges of chlorinated volatile organics (CVOCs) resulting in Trichloroethene (TCE) at high concentrations and varying lower concentrations of TCE degradation products, including cis-1,2-Dichloroethene (DCE), and Vinyl Chloride (VC). Two primary source areas were identified in soil with a distinct groundwater plume associated with each area. The developer had specific timelines that had to be met before building construction could proceed therefore the remedia-
