This book was released on 1996 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1999 with total page 703 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: This report describes a study of groundwater conditions at Installation Restoration Program (IRP) Site 4, Langley Air Force Base (AFB), Virginia. Site 4 is a former underground fuel storage area previously identified as a possible source of fuel contaminated soil and shallow groundwater in the immediate area. Two other possible sources of fuel were identified during the present study. One is the underground distribution system associated with the former fuel storage area. The other is an underground pipeline in current use. All three remain under consideration as possible sources of leaking fuel.

This book was released on 1995 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
