This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of an Engineering Evaluation/Cost Analysis (EE/CA) performed by Parsons Engineering Science, Inc. (Parsons ES) at Plattsburgh Air Force Base, New York, to evaluate if naturally occurring attenuation mechanisms would be sufficient to reduce dissolved fuel-related compounds in shallow ground water at and migrating from the former Fire Training Area (Site FT-002) to levels that meet federal- and state-specified ground water protection standards. Several site investigations completed at Site FT-002 under the Department of Defense (DOD) Installation Restoration Program (IRP) indicate that the soil and ground water associated with and downgradient of the former fire training area is contaminated with JP-4-related compounds and chlorinated solvents. Significant light nonaqueous phase liquid (LNAPL) still exists at the site, which acts as a continuing source of contamination mass to the ground water. The main emphasis of the work described herein was to quantitatively investigate the fate and transport of dissolved benzene, toluene, ethylbenzene, and total xylenes (BTEX) in the shallow ground water at the site. The fate and transport of dissolved chlorinated solvents (i.e., trichloroethene (TCE), cis- and trans-dichloroethene (DCE), and vinyl chloride) in shallow ground water was qualitatively considered to evaluate whether remedial technologies that may be appropriate for the BTEX compounds would also be effective on these other site-related contaminants.

This book was released on 1996 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of the investigation performed by Parsons Engineering Science, Inc. (Parsons ES) at Seymour Johnson Air Force Base (AFB), North Carolina to evaluate the use of intrinsic remediation (natural attenuation) with long-term monitoring (LTM) as a remedial option for dissolved benzene, toluene, ethylbenzene, and total xylenes (BTEX) contamination in shallow groundwater. Parsons ES conducted the field investigation during the period between January and July 1995 at the former aerospace ground equipment (AGE) fueling facility site (adjacent to Building 4715). The source of the contamination is assumed to be releases from an abandoned underground storage tank (UST) system that was formerly used to store gasoline, JP-4, and diesel fuel. BTEX and total volatile hydrocarbons (TVH) were determined to be dissolved in groundwater and adsorbed to soils. Residual light non-aqueous phase liquid (LNAPL) was found in the soil column (at the groundwater interface) in the immediate vicinity of the former UST system. Also, mobile LNAPL (free product) was observed in several monitoring points installed during the investigation. This study focused on the impacts of the dissolved BTEX and residual and mobile LNAPL on the shallow groundwater system at the site. Potential electron acceptors and other geochemical parameters were analyzed to quantify ongoing biodegradation. An important component of this study was an assessment of the potential for contamination in groundwater to migrate from the former AGE fueling facility site to potential receptor exposure points. The Bioplume II model was used to estimate the fate and transport of dissolved BTEX in the shallow saturated zone under the influence of advection, dispersion, sorption, and biodegradation. Whenever possible, input parameters for the Bioplume II model were obtained from data collected by Parsons ES during 1995. Extensive site-specific data were used for model calibration and implementation.
