Book Description
This work plan was prepared by Parsons Engineering Science, Inc. (Parsons ES), formerly Engineering Science, Inc. (ES), and presents the scope of work required for the collection of data necessary to conduct a treatability study (TS) for the intrinsic remediation of groundwater contaminated with petroleum hydrocarbons and chlorinated aliphatic hydrocarbons (CAHs) at the Priority-One Site Fire Training Area 01 (FT-1) located at Fairchild Air Force Base (AFB), 12 miles west of Spokane, Washington (the Base). The record-of-decision (ROD) for FT-1 specifies the use of air sparging to remediate volatile organic compounds (VOCs) in site groundwater. Therefore, this TS will assess naturally occurring contaminant attenuation processes for groundwater and evaluate how these processes will operate in conjunction with the future air sparging system. This work plan is oriented toward the collection of hydrogeologic data to be used as input into groundwater flow and solute transport models to evaluate intrinsic remediation for restoration of groundwater contaminated with benzene, toluene, ethylbenzene, xylenes (BTEX), and CAHs. As used in this report, the term "intrinsic remediation" refers to a management strategy that relies on natural attenuation mechanisms to remediate contaminants dissolved in groundwater and to control the potential for receptor exposure to site-related contaminants in the subsurface. "Natural attenuation" refers to the actual physical, chemical, and biological processes that facilitate intrinsic remediation. Mechanisms for natural attenuation of BTEX and CAHs include advection, dispersion, dilution from recharge, sorption, volatilization, and biodegradation. Of these processes, biodegradation is the only mechanism working to transform contaminants into innocuous byproducts. Intrinsic bioremediation occurs when indigenous microorganisms work to bring about a reduction in the total mass of contamination in the subsurface without the addition of nutrientc.

Book Description
This work plan, prepared by Parsons Engineering Science, Inc. (Parsons ES), formerly Engineering-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 and chlorinated organic compounds located at Site 1 (Hazardous Waste Storage Area) at Rickenbacker Air National Guard Base (the Base), in Lockbourne, Ohio. Several remedial options will be evaluated during the TS, including free product removal; bioventing for source removal; 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 primarily oriented toward the collection of hydrogeologic data to be used as input into the Bioplume II groundwater model in support of intrinsic remediation for restoration of fuel-hydrocarbon-contaminated groundwater.

This work plan, prepared by Parsons Engineering Science, Inc. (Parsons ES), formerly Engineering 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 the Flightline Operable Unit PS-2 (PS-2) located at Fairchild Air Force Base (AFB), 12 miles west of Spokane, Washington (the Base). Several groundwater remedial options will be evaluated as a part of the TS report, including: bioslurping; groundwater extraction, treatment, and disposal (i.e., pump and treat); biosparging; and natural contaminant attenuation (intrinsic remediation) with long-term monitoring. 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 groundwater flow and solute transport models in support of intrinsic remediation for restoration of groundwater contaminated with benzene, toluene, ethylbenzene, and xylene (BTEX).

Book Description
This work plan, prepared by Parsons Engineering Science, Inc. (Parsons ES), formerly Engineering 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 and solvents at Site FT-03, the Current Fire Training Area, and Site FT-03, Christmas Tree Fire Training Area, located at Westover Air Reserve Base (ARB) in Chicopee, Massachusetts (the Base). Several remedial options will be evaluated during the TS, including free-phase product removal (if present); groundwater extraction, treatment, and disposal (i.e., pump and treat); bio-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 groundwater flow and solute transport models in support of intrinsic remediation for restoration of fuel-hydrocarbon and chlorinated solvent contaminated groundwater.

Book Description
This work plan, prepared by Parsons Engineering Science, Inc. (Parsons ES), formerly Engineering-Science, Inc. (ES), presents the scope of work required for the collection of data necessary to develop a treatability study (TS). The TS will address remediation of ground water contaminated with petroleum hydrocarbons at Sites OT-1 and SS-42 (near Building 5009) at Wurtsmith Air Force Base (Base), in Oscoda, Michigan. This work plan is oriented toward the collection of hydrogeologic and chemical data that will be used to document the occurrence of intrinsic remediation of benzene, toluene, ethylbenzene, and xylenes (BTEX) dissolved in ground water. Intrinsic remediation is a risk management strategy that relies on natural attenuation to control the risks associated with exposure to contaminants in the subsurface. However, data collected under this program will also allow for the evaluation of several remedial options, such as free product removal; bioventing for source removal; air sparging; and intrinsic remediation with long-term monitoring (LTM). This work plan was developed based on discussions among representatives from the Air Force Center for Environmental Excellence (AFCEE) Technology Transfer Division, Michigan Department of Natural Resources (MDNR), Wurtsmith AFB, and Parsons ES at a meeting at the Base on August 24, 1994.

Book Description
This work plan, prepared by Parsons Engineering Science, Inc. (Parsons ES), formerly Engineering-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 Building 1212 located at Fairchild Air Force Base (AFB), 12 miles west of Spokane, Washington (the Base). Hydrogeological and groundwater chemical data collected under this program can be used to evaluate various remedial options; however, this work plan is oriented toward the collection of hydrogeological data to be used as input into groundwater flow and solute transport models in support of remediation by natural attenuation (RNA) with long-term monitoring (LTM) for restoration of groundwater contaminated with benzene, toluene, ethylbenzene, and xylene (BTEX). As used in this report, RNA refers to a management strategy that relies on natural attenuation mechanisms to remediate contaminants dissolved in groundwater and to control receptor exposure risks associated with contaminants in the subsurface. The United States Environmental Protection Agency (US EPA) Office of Research and Development (ORD) and Office of Solid Waste and Emergency Response (OSWER) define natural attenuation as: The biodegradation, dispersion, sorption, volatilization, and/or chemical and biochemical stabilization of contaminants to effectively reduce contaminant toxicity, mobility, or volume to levels that are protective of human health and the ecosystem. As suggested by this definition, mechanisms for natural attenuation of BTEX include advection, dispersion, dilution from recharge, sorption, volatilization, and biodegradation. Of these processes, biodegradation is the only mechanism working to transform contaminants into innocuous byproducts.
