Intrinsic Remediation Engineering Evaluation/Cost Analysis for the Former Car Care Center, Bolling Air Force Base, Washington, District of Columbia
Abstract
This report was prepared for the Air Force Center for Environmental Excellence (AFCEE) by Parsons Engineering Science, Inc. (Parsons ES) as an addendum to the Final Intrinsic Remediation Engineering Evaluation/Cost Analysis (EE/CA) for the Former Car Care Center, Bolling Air Force Base (AFB), Washington, District of Columbia (DC) (Parsons ES, 1997a). The EE/CA was conducted to evaluate the use of natural attenuation (intrinsic remediation) with longterm monitoring (LTM) for remediation of fuel hydrocarbon contamination dissolved in groundwater at the Former Car Care Center. This addendum summarizes the results of the third sampling event performed as a part of the evaluation of natural attenuation at the site. This sampling was conducted in September 1997 by researchers from the US Environmental Protection Agency (USEPA) National Risk Management Research Laboratory (NRMRL) Subsurface Protection and Remediation Division. The original EE/CA sampling event was conducted in August 1994, and the first natural attenuation update sampling occurred in June 1996. The main emphasis of this summary is to evaluate changes in dissolved benzene, toluene, ethylbenzene, and xylenes (BTEX) concentrations, plume extent, and natural attenuation mechanisms through time. Results, calculations, and predictions presented in the EE/CA are used as the basis for comparison.
