Book Description
This report presents the results of a treatability study for remediation by natural attenuation (RNA TS), completed by Parsons Engineering Science, Inc. (Parsons ES) at IRP Site SS-04, Langley Air Force Base (AFB),Virginia. The TS evaluates the use of natural attenuation with long-term monitoring (LTM) as a remedial option for dissolved hydrocarbon fuel constituents in groundwater. The occurrence of groundwater and soil contamination at the site, as a consequence of leakage of petroleum-based fuel (jet fuel or JP-4), has been documented during previous investigations. This TS focuses primarily on the impact of dissolved fuel constituents, in particular benzene, toluene, ethylbenzene, and xylene isomers (BTEX), in the groundwater system at, and downgradient from, the source area. Residual fuel hydrocarbon contamination in soil surrounding the source area (the abandoned USTs) was remediated from 1992 through 1996 with a vapor extraction system. The site history and the results of previously- completed soil and groundwater investigations are summarized in this report. Soil and groundwater samples were collected from the site and analyzed to obtain the information necessary for the transport evaluation and RNA demonstration. Physical and chemical data collected under this program were supplemented (where necessary) with data collected during previous site characterization investigations and monitoring events. Biodegradation of fuel hydrocarbons can occur when an indigenous population of hydrocarbon-degrading microorganisms is present in the subsurface, and sufficient concentrations of electron acceptors, nutrients, and electron donors (including fuel hydrocarbons) are available to these organisms. Several lines of chemical and geochemical evidence indicate that dissolved BTEX constituents are undergoing biodegradation within and downgradient from the contaminant source area.

Book Description
This report was prepared by Parsons Engineering Science, Inc. (Parsons ES) and presents the results of a treatability study (TS) conducted to evaluate the use of intrinsic remediation for remediation of fuel-hydrocarbon-contaminated groundwater at Installation Restoration Program (IRP) Site S 5-16 (a former military gasoline service station site) at Langley Air Force Base (AFB, the Base), in Hampton, Virginia. Previous investigations determined that fuel hydrocarbons had been released into the soil and shallow groundwater at the site. The main emphasis of the work described herein was to evaluate if naturally occurring attenuation mechanisms would be sufficient to reduce dissolved fuel-related compounds in groundwater to levels that meet state-specified groundwater protection standards. This study is not intended to be a contamination assessment report or a remedial action plan; rather, it is provided for the use of the Base and its prime environmental contractor(s) as information to be used for future decision making regarding this site.

Book Description
This work plan, prepared by Parsons Engineering Science, Inc. (Parsons ES) formerly Science, Inc. (ES), presents the scope of work required for the collection of data necessary to conduct a treatability study (TS) for remediation of groundwater contaminated with petroleum hydrocarbons at Installation Restoration Program (IRP) Site SS-16 (a former military gasoline service station site), Langley Air Force Base (AFB) in Hampton, Virginia. Hydrogeologic and groundwater chemical data necessary to evaluate multiple remedial options will be collected under this program; however, this work plan is primarily oriented toward the collection of Hydrogeologic data to be used in support of intrinsic remediation (natural attenuation) for restoration of fuel-hydrocarbon- contaminated groundwater. Other remedial options will be considered in conjunction with intrinsic remediation during the TS, including free product removal; groundwater extraction and treatment (i.e., pump and treat); biosparging; bioslurping; and long-term monitoring.

Book Description
This report presents the results of a remediation by natural attenuation treatability study (RNA TS) performed by Parsons Engineering Science, Inc. (Parsons ES) at Operable Unit 1 (OU-1), Landfill 4 (LF-04), Altus Air Force Base, Oklahoma to evaluate the use of natural attenuation with long-term monitoring (LTM) as a remedial option for dissolved chlorinated aliphatic hydrocarbon (CAH) contamination in the surficial water- bearing zone. The presence of groundwater contamination at the site was documented during the remedial investigation performed by the United States Geological Survey (USGS, 1996). This TS focused on the impact of dissolved CAHs on groundwater and surface water at and downgradient from the site. Site history and the results of soil, groundwater, and surface water investigations conducted previously also are summarized in this report.

Book Description
This report presents the results of a treatability study performed by Parsons Engineering Science. Inc. (Parsons ES) at UST Sites 10-494, 10-495, and 10-496 (UST Site) Beale Air Force Base. California to evaluate the use of remediation by natural attlenuation (RNA) with long-term monitoring (LTM) as a remedial option for dissolved benzene. toluene. ethylbenzene, and xylene (BTEX) and total petroleum hydrocarbons as gasoline (TPH-g) contamination in the shallow groundwater. This study focused on the impact of dissolved BTEX and TPH-g compounds on the shallow groundwater system at the site. Site history and the results of soil and groundwater investigations conducted previously are also summarized in this report.

Book Description
This report presents the results of a treatability study (TS) performed by Parsons Engineering Science, Inc. (Parsons ES) at Operable Unit 4 (OU-4) at Shaw Air Force Base, South Carolina, to evaluate remediation by natural attenuation (RNA) of dissolved chlorinated aliphatic hydrocarbons (CAHs) and fuel hydrocarbons in groundwater. The TS focused on the fate and transport of dissolved CAHs, particularly 1,1, 1-trichloroethane (1,1, 1-TCA), which is present at high concentrations at the site. Petroleum hydrocarbons INCLUDING BENZENE, TOLUENE, ETHYLBENZENE, AND XYLENES (BTEX) also are present in site groundwater and were considered in this TS. The site history and the results of the soil and groundwater investigations conducted previously also are summarized in this report.

Book Description
This report presents the results of a treatability study performed by Parsons Engineering Science, Inc. (Parsons ES) at the FT-1 Site, Fairchild Air Force Base, Washington to evaluate remediation by natural attenuation (RNA) of dissolved fuel-hydrocarbons and chlorinated solvents in the shallow groundwater. RNA will supplement the engineered remedial actions prescribed in the Record of Decision (ROD). Residual nonaqueous-phase liquid (NAPL) present within the vadose zone and phreatic soils serves as a continuing source for the dissolved groundwater contamination. There is no evidence of mobile NAPL at this site. This study focused on the fate and transport of dissolved benzene, toluene, ethylbenzene, and xylene (BTEX) in the shallow groundwater system at the site. Dissolved chlorinated aliphatic hydrocarbons (CAHs) also are present in the shallow groundwater; therefore, the potential for RNA of these compounds was investigated as well. Site history and the results of soil and groundwater investigations conducted previously are also summarized in this report. Comparison of BTEX, CAH, electron acceptor, and biodegradation byproduct isopleth maps for Site FT-1 provides strong.

Book Description
This report presents the results of a remediation by natural attenuation treatability study (RNA TS) performed by Parsons Engineering Science, Inc. (Parsons ES) at Operable Unit 5 (OU5), Hil Air Force Base, Utah to evaluate the use of natural attenuation with long-term monitoring (LTM) as a remedial option for dissolved chlorinated aliphatic hydrocarbon (CAH) contamination and soil contamination at the site was documented during the remedial investigation performed by Radian International (Radian). This TS focused on the impact of dissolved CAHs, promarily trichloroethene (TCE), on the shallow groundwater system at and downgradient from the site. Site history and the results od soil, groundwater, and surface water investigations conducted previously also are summarized in this report. Several lines of chemical and geochemical evidence indicate that, although dissolved CHAs are undergoing biologically facilitated reductive dehalogenation, the occurrence of this process is limited and localized.
