Addendum to the Intrinsic Remediation Engineering Evaluation/Cost Analysis (EE/CA) for the Former AGE Fueling Facility Site.

摘要

This report presents the results of an addendum to the Intrinsic Remediation Engineering Evaluation/Cost Analysis (EE/CA) for the Former Aerospace Ground Equipment (AGE) Fueling Facility Site performed by Parsons Engineering Science (Parsons ES) at Seymour-Johnson Air Force Base (AFB), North Carolina (Parsons ES, 1996). The EE/CA was conducted to evaluate the use of intrinsic remediation with long-term monitoring (LTM) to address fuel- hydrocarbon-contaminated groundwater at the AGE Site. This addendum to the EE/CA summarizes the results of a groundwater sampling event conducted in April 2001 by the United States Environmental Protection Agency (US EPA) National Risk Management Research Laboratory (NRMRL) Subsurface Protection Division and Parsons ES. Results of this sampling event are used to evaluate spatial and temporal trends of groundwater contaminants at the AGE Site.
