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.
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.
This work plan, prepared by Parsons Engineering Science, Inc. (Parsons ES), presents the scope of work required for the collection of data necessary to conduct an engineering evaluation/cost analysis (EE/CA) for remediation of groundwater contaminated with petroleum products at the former Aerospace Ground Equipment (AGE) fueling facility adjacent to Building 4715 located at Seymour Johnson Air Force Base (AFB), Goldsboro, NC. This EE/CA will provide the framework for the site's Corrective Action Plan under the North Carolina requirements. Several remedial options will be evaluated during the EE/CA possibly including free product removal; groundwater extraction, treatment, and reinjection (i.e., pump and treat); air sparging; and natural contaminant attenuation (intrinsic remediation) with long-term monitoring. All hydrogeologic and groundwater 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 in support of intrinsic remediation for restoration of fuel-hydrocarbon-contaminated groundwater. When applicable, site-specific information may be obtained from previous studies conducted at Seymour Johnson AFB.
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 benzene, toluene, ethylbenzene, and xylene (BTEX) contamination in the shallow saturated zone in the vicinity of Site ST41 (locally known as Four Million Gallon Hill). For this report, Site ST4l was studied only in the vicinity of the BTEX plume emanating from Tank 601. 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 also evidence of mobile LNAPL (free product) at this site. This study focused on the impact of dissolved 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.
This work plan, prepared by Engineering-Science, Inc. (ES), presents the scope of work required for the collection of data necessary to conduct an engineering evaluation/cost analysis (EE/CA) for remediation of groundwater contaminated with JP-4 jet fuel at fuel pumping station 950 at site SS27/XYZ located at Dover Air Force Base (AFB), Delaware. Several remedial options will be evaluated during the EE/CA, including free product removal; groundwater extraction, treatment, and reinjection (i.e., pump and treat); air sparging; and natural contaminant attenuation (intrinsic remediation) with long-term monitoring. All hydrogeologic and groundwater 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 groundwater model in support of intrinsic remediation for restoration of fuel-hydrocarbon-contaminated groundwater.
In 1995, the US Department of Energy (DOE), Richland Operations Office (RL) conducted a removal site evaluation of selected facilities in the 100 Area of the Hanford Site in accordance with CERCLA and 40 Code of Federal Regulations (CFR) 300.410. The scope of the evaluation included the aboveground portions of the 108-F Biology Laboratory in the 100-F Area and all inactive ancillary buildings and structures in the 100-B/C Area, excluding the reactor building and the river outfall. Based on the evaluation, RL determined that hazardous substances in the 108-F Biology Laboratory and five of the 100-B/C Area facilities may present a potential threat to human health or the environment, and that a non-time critical removal action at these facilities is warranted. This determination was documented in an engineering evaluation/cost analysis (EE/CA) approval memorandum. The EE/CA approval memorandum is the basis on which to proceed with the performance of an EE/CA to determine the appropriate removal action. This report presents the results of the EE/CA for removal alternatives for final disposition of these six facilities. The EE/CA was conducted pursuant to the requirements of CERCLA and 40 CFR 300.415 and is intended to aid RL and the EPA in selecting a preferred removal action.
Parsons Engineering Science, Inc. (Parsons ES), formerly Engineering-Science, Inc. (ES), was retained by the United States (US) Air Force Center for Environmental Excellence (AFCEE) to prepare an engineering evaluation/cost analysis (EE/CA) in support of a risk-based remediation decision for soil and groundwater contaminated with fuel hydrocarbons at Pumphouse #2, a former fuel storage and pumping facility at Malmstrom Air Force Base (AFB), in Great Falls, Montana (the Base). Risk-based remediation is designed to combine natural physical, chemical, and biological processes with low-cost source removal technologies such as in situ bioventing, as necessary, to economically reduce potential risks posed by subsurface petroleum fuel spills. A decision diagram for the risk-based process is shown in Figure 1.1.
As part of the EE/CA, the Bioplume II modeling effort has three primary objectives: (1) to predict the future extent and concentration of the dissolved-phase contaminant plume by modeling the effects of advection, dispersion, sorption, and biodegradation; (2) to assess the possible risk to potential downgradient receptors; and (3) to provide technical support for selection of the intrinsic remediation option as the best remedial alternative at regulatory negotiations, as appropriate. The Bioplume II modeling effort for this site will involve completion of several tasks, which are described in the following sections.
