Intrinsic Remediation Engineering Evaluation/Cost Analysis for Car Care Center at Bolling Air Force Base, Washington, DC
Abstract
This report presents the results of the investigation performed by Parsons Engineering Science, Inc. (Parsons ES) at Bolling Air Force Base (AFB), District of Columbia to evaluate the use of intrinsic remediation (natural attenuation) with long-term monitoring (LTM) as a remedial option for dissolved benzene, toluene, ethylbenzene, and xylene (BTEX) contamination in the shallow saturated zone. Parsons ES conducted field investigations during August 1994 and June 1996 at the former Car Care Center Site (Building 4). The source of the contamination was leaking underground storage tanks and other associated equipment. BTEX and total volatile hydrocarbons (TVH) was determined to be dissolved in groundwater and absorbed to soils. Residual light nonaqueous phase liquid (LNAPL) was found throughout the soil column, both above and below the groundwater interface. However, minimal mobile LNAPL (free product) was observed at the site during the field investigations. This study focused on the impact of dissolved BTEX and residual LNAPL on the shallow groundwater system at the site.
