Book Description
This report presents the results of an engineering evaluation/cost analysis (EE/CA) performed by Parsons Engineering Science, Inc. (Parsons ES) at Elmendorf Air Force Base, Alaska to evaluate the use of intrinsic remediation (natural attenuation) with long-term monitoring (LTM) as a remedial option for dissolved-phase benzene, toluene, ethylbenzene, and xylene (BTEX) contamination in the shallow saturated zone in the vicinity of Hangar 10. Soil and ground water contamination is known to occur at the site, with contamination being present in the dissolved and gaseous phases and as residual light nonaqueous-phase liquid (LNAPL) within the aquifer matrix. There is no evidence of mobile LNAPL (free product) at this site. This study focused on the impact of dissolved-phase BTEX on the shallow ground water system at the site. Site history and the results of soil and ground water investigations conducted previously are also summarized in this report. An important component of this study was an assessment of the potential for contamination in ground water to migrate from the Hangar 10 site to potential receptors. The Bioplume II model was used to estimate the rate and direction of dissolved-phase BTEX movement through the shallow saturated zone under the influence of advection, dispersion, sorption, and biodegradation. Input parameters for the Bioplume II model were obtained from existing site characterization data, supplemented with data collected by Parsons ES in conjunction with personnel from the United States Environmental Protection Agency (USEPA) Robert S. Kerr Environmental Research Laboratory. Extensive site-specific data were used for model implementation. The results of this study suggest that dissolved-phase BTEX contamination present in ground water poses no significant risk to human health or the environment in its present, or predicted future, concentration and distribution. predicted future, concentration and distribution.

Book Description
This work plan was prepared by Engineering-Science, Inc. (ES) and presents the scope of work required for the collection of data necessary to conduct an engineering evaluation/cost analysis (EE/CA) for remediation of fuel-hydrocarbon-contaminated ground water at two sites at Elmendorf Air Force Base (AFB), Anchorage, Alaska. The two sites to be addressed are the Hangar 10 site and site ST4l (locally known as Four Million Gallon Hill). Several remedial options will be evaluated during the EE/CA, including free product removal; ground water extraction, treatment, and re-injection (i.e., pump and treat); air sparging; and intrinsic remediation with long-term monitoring (intrinsic remediation). All hydrogeologic and ground water chemical data necessary to evaluate the various remedial options will be collected under this program; however, this work plan is oriented toward the collection of hydrogeologic data to be used as input into the Bioplume II ground water model in support of the intrinsic remediation (intrinsic remediation) with long-term monitoring remedial option for restoration of fuel hydrocarbon-contaminated ground water.

Book Description
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.

Book Description
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.

Book Description
The intent of the EE/CA Addendum was to determine the role of natural attenuation in remediating fuel contamination in groundwater at Site 870. The EE/CA was conducted to evaluate the use of intrinsic remediation with long-term monitoring (LTM) for remediation of fuel hydrocarbon contamination dissolved in groundwater at UST Site 870. This update summarizes the results of the third sampling event performed as part of long-term groundwater monitoring at the site. This sampling was conducted in September 1998 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 1993 with the first long-term sampling occurring in July 1994 and the second long-term sampling occurring in September 1995. The main emphasis of this summary is to evaluate changes in dissolved benzene, toluene, ethylbenzene, and xylene (BTEX) concentrations, plume extent, and natural attenuation mechanisms through time.

Book Description
This work plan was prepared by Engineering-Science, Inc. (ES) for the Air Force Center for Environmental Excellence (AFCEE). It presents the scope of work required for the collection of data necessary to conduct an engineering evaluation/cost analysis (EE/CA) for remediation of two fuel-hydrocarbon-contaminated ground water sites at King Salmon Airport (KSA), in King Salmon, Alaska. The two sites to be addressed in this work plan are Fire Training Area No. 1 (Site FT01) and the Upper Naknek site (Site SS12). Investigations have been previously undertaken at both sites as part of the U S Air Force (USAF) Installation Restoration Program (IRP). Several remedial options will be evaluated during the EE/CA, including free product removal; ground water extraction, treatment, and re-injection (i.e., pump and treat); and intrinsic remediation with long-term monitoring (intrinsic remediation). All hydrogeologic and ground water chemical data necessary ;to evaluate the various remedial option will be collected under this program; however, this work plan is oriented primarily toward the collection of hydrogeologic data to be used as input into the Bioplume II (trade name) ground water model in support of the intrinsic remediation option for restoration of fuel-hydrocarbon-contaminated ground water.
