Management Action Plan (MAP), Hickam AFB (Back to Top)

Description of the MAP (Back to Top)

  • As a result of past (pre-1984) waste and resource management practices at Hickam AFB, certain areas of the installation have been exposed to various organic and inorganic compounds generated by installation activities. In response, environmental restoration has been initiated under the U.S. Air Force (USAF) Installation Restoration Program (IRP). The 15th Airlift Wing (15 AW), 15th Civil Engineer Squadron/Environmental Restoration Element (15 CES/CEVR), based at Hickam AFB manages the IRP for 15 AW installations.
  • This MAP summarizes the status of the Hickam AFB IRP and provides a comprehensive long-range strategy for implementing response actions necessary to protect human health and the environment. In addition, it defines the status of the 15 CES/CEVR efforts to resolve technical issues so that continued progress and implementation of scheduled activities can occur. The MAP is a dynamic planning document. The contents represent best estimates of required work and do not necessarily represent work currently approved by the U.S. Air Force or by State and federal regulatory agencies.
  • Contained in this document are past IRP activities at Hickam AFB, the current status of projects, and anticipated further work.

Base-Wide Ambient Metals Study (Back to Top)

Description of the Base-Wide Ambient Metals Study (Back to Top)

  • The 15th Airlift Wing Civil Engineer Squadron/Environmental Restoration Element (15 CES/CEVR) at Hickam Air Force Base (AFB) and the Air Force Center for Environmental Excellence (AFCEE) have conducted a study to characterize ambient concentrations of metals in soil and groundwater across Hickam AFB.
  • Metals are naturally present in soil and groundwater at varying concentrations, and they may also result from human influences. These influences may include site-related contaminant releases at the Base, but they also may be associated with urban, industrial, and agricultural development. The Air Force is interested in developing a better understanding of the concentrations of ambient metals in soil and groundwater at the Base (“ambient concentrations” are defined as the naturally occurring concentrations plus human-influenced concentrations that are not related to specific contaminant releases at the Base). The Air Force will use the data provided by this study to support decisionmaking at sites where metals may pose unacceptable risks to humans and/or the environment.

Land Use Control Implementation Plan (LUCIP) (Back to Top)

Description of LUCIP Report (Back to Top)

  • This Report addresses the established and proposed land use controls (LUCs) for Installation Restoration Program (IRP) sites and areas of concern (AOCs) at Hickam Air Force Base (AFB), Bellows Air Force Station (AFS), and Kaala AFS. To date, there are no LUCs established for any sites or AOCs at Kaala AFS.
  • This report also defines the responsibilities and procedures for implementing, managing, enforcing and tracking LUCs and, when appropriate, modifying or terminating LUCs. The purpose of this plan is twofold:
    • To provide Base entities and personnel involved in facility management and project planning, design and implementation with information on the LUCs and LUC restrictions and guidance for ensuring LUC compliance.
    • To provide documentation to regulatory agencies regarding implementation and management of LUCs identified in approved Hickam AFB and Bellows AFS decision documents.

15th Airlift Wing Installation Restoration Program Well Closure Procedures (Back to Top)

Description of the 15th Airlift Wing Installation Restoration Program Well Closure Procedures (Back to Top)

  • The 15th Airlift Wing (15 AW) Civil Engineer Squadron/Environmental Restoration Element (15 CES/CEVR), located at Hickam Air Force Base (AFB), will be monitoring well-closure procedures that will be conducted in support of Installation Restoration Program (IRP) activities administered for multiple sites under the Defense Environmental Restoration Program (DERP).
  • Subsequent to serving the purpose for which they were constructed, monitoring wells must be properly decommissioned in order to reduce the potential that they could become a conduit for contaminants to impact groundwater. The wide variety of geological, hydrogeological, physical, and chemical conditions that can be found at different locations demand that site-specific decommissioning practices be developed. In each case, 15 CES/CEVR will select the most efficient and cost-effective option for the abandonment of monitoring wells at 15 AW installations in Hawaii.
  • A project Work Plan will be prepared and is intended to provide general guidance on well decommissioning (also defined as well abandonment or closure) at IRP sites within Hickam AFB, as well as at other 15 AW installations. Site-specific background information relative to individual wells undergoing closure will be provided in separate site-specific work plan addenda, along with site-specific health and safety plans.

Multiple Areas of Concern Site Inspection, NFRAPs (TO 97) (Back to Top)

Description of Task Order 97 (Back to Top)

  • This project consisted of conducting Site Investigations for 23 Areas of Concern (AOCs) located throughout Hickam Air Force Base.


  • The project's primary goal was to collect additional field sampling data to better evaluate environmental conditions at each of the 23 AOCs and identify which AOCs contain chemical concentrations that potentially pose unacceptable risks to human health or the environment. The results of the SI are intended to provide the Air Force and the HDOH with sufficient information about each area to determine whether further action is necessary, or whether site closure may be pursued. However, it is not the intention of the SI project to delineate the extent of contamination or conduct quantitative risk assessments, although such efforts may be required in the future for certain AOCs that require further action.


  • The decision to pursue further action or not is accomplished by comparing the analytical results of environmental sampling at each AOC to recently published HDOH Environmental Action Levels (EALs). This allows potential risks to human health and the environment posed by residual chemicals at a given AOC to be consistently evaluated through a standard, semi-quantitative risk-based process. Accordingly, AOCs judged to pose potential health or environmental risks are recommended for further action. AOCs found to be free of significant contamination are recommended for No Further Response Action Planned (NFRAP) status (that is, site closure)


  • The scope of the SI project entails three main tasks:
    • Reviewing, evaluating, and incorporating available historical information and sampling data
    • Identifying current data gaps at each AOC
    • Collecting additional field sampling data to fill data gaps and permit defensible risk-based screening and risk characterization for each AOC

Sites CG110 and SS101 Remedial Investigation and Feasibility Study (TO 98 and TO 339) (Back to Top)

Description of Task Orders 98 and 339 (Back to Top)

  • Sites CG110 and SS101 include multiple former areas of concern (AOCs) that have been previously investigated by the Air Force under different projects. Site CG110 comprises former AOCs EA10 (incorporating also former AOC AM04) and EA22; Site SS101 comprises former AOCs EA69, AM2F, and AM10. Earlier investigations have shown that soil and groundwater at these sites have been contaminated by volatile organic chemicals (VOCs), petroleum hydrocarbons, and metals (particularly lead).

  • The overall objective of the proposed Remedial Investigation / Feasibility Study (RI/FS) is therefore to better delineate the nature and extent of the contamination at Sites CG110 and SS101 and to characterize the resultant risks to human health and the environment. If unacceptable risks are found to exist, remedial technologies that remove or mitigate the identified risks will be evaluated, and a remedial strategy will be selected and documented in a Record of Decision (ROD). Alternatively, if risks are found to be within acceptable limits (a risk range of 10-4 to 10-6 for cancer risk or less than one for non-cancer risk ) then the site will be closed and assigned No Further Response Action Planned (NFRAP) status.


  • To achieve this objective, this project consists of the following primary tasks:


    • Preparation of project work plans
    • Field investigations (including field screening, soil and groundwater sampling, monitoring well installation, and soil-gas sampling)
    • Onsite and offsite analysis of environmental samples
    • Data validation and tabulation
    • Data evaluation
    • Human health and environmental risk assessment
    • Identification of general response actions and applicable remedial technologies
    • Evaluation of remedial alternatives
    • Identification of preferred remedial action
    • Documentation of selected remedy


  • Field work will be conducted under three separate phases. To help streamline the RI/FS process, and in recognition of the uncertainties currently associated with the sources and nature and extent of contamination at both sites, a Triad approach will be used to design and implement all the different investigation phases. The Triad approach will use a combination of systematic project planning, dynamic work strategies, and real-time measurement technologies to optimize data collection, accelerate project schedule, and minimize unnecessary re-mobilization of field teams at later stages of the project. The primary objective of the Triad approach is to manage technical and administrative decision uncertainties by involving the project stakeholders at the work-planning stage, and developing a flexible site investigation approach to ensure that the optimum amount of relevant data will be collected using the most efficient and cost-effective methods available.

Sites DP105 and DD119 Remedial Investigation and Feasibility Study (TO452) (Back to Top)

Description of Task Order 452 (Back to Top)

  • The Air Force is planning to conduct a Remedial Investigation/Feasibility Study (RI/FS) at two sites, DP105 and DD119, on Hickam Air Force Base (AFB), Oahu, Hawaii. The purpose of the studies is to further investigate and delineate contamination uncovered at the sites during previous investigations, most recently the SI for Multiple AOCs project that was completed in July 2006. The work is being conducted in consultation with the State of Hawaii Department of Health (HDOH).

    Based on the results of the SI, additional remedial investigation was recommended for Site DP105 because volatile organic compounds (VOCs), metals, petroleum hydrocarbons (TPH), and polynuclear aromatic hydrocarbons (PAHs) were found in the residual sump sludge at concentrations above HDOH Environmental Action Levels (EALs). The Air Force is concerned that the contaminated sludge remaining in the sump may have acted as a source of contaminants to the soil and groundwater beneath Building 2002.

    Additional remedial investigation was also recommended for Site DD119 because of the presence of metals, PAHs, pesticides, and polychlorinated biphenyls (PCBs) in debris pile soils at levels above applicable HDOH EALs. The concern exists that the contaminated debris pile may have acted as a source of contamination to the underlying site soil and groundwater. Based on the historical data, the debris does contain low-level contamination. Removal of the debris will allow access to the site for the additional investigation. It is anticipated that most of the debris will be disposed of on-island as non-hazardous waste.

    Following completion of the debris sorting and removal activities at Site DD119, the RI sampling activities will be used to determine the extent of contamination present on the native Site DD119 soil and groundwater.



  • The overall objective of the proposed Remedial Investigation / Feasibility Study (RI/FS) is therefore to better delineate the nature and extent of the contamination at Sites DP105 and DD119 and to characterize the resultant risks to human health and the environment. Following completion of the RI/FS projects, two outcomes are possible: site closure or site remediation. If contaminant concentrations are below applicable HDOH EALs or the associated risks are within acceptable ranges, then the site may be recommended for no further action and final closure. However, if contaminant concentrations and associated risks are judged to be above acceptable ranges, then additional action will be needed to identify the appropriate remedial approach.


  • To achieve this objective, this project consists of the following primary tasks:


    • Preparation of project work plans for Sites DP105 and DD119 and a Debris Sorting work plan for Site DD119
    • Field investigations (including field screening, soil and groundwater sampling, monitoring well installation, and soil-gas sampling)
    • Onsite and offsite analysis of environmental samples
    • Data validation and tabulation
    • Data evaluation
    • Human health and environmental risk assessment
    • Identification of general response actions and applicable remedial technologies
    • Evaluation of remedial alternatives
    • Identification of preferred remedial action
    • Documentation of selected remedy


  • Field work will be conducted under three separate phases. To help streamline the RI/FS process, and in recognition of the uncertainties currently associated with the sources and nature and extent of contamination at both sites, a Triad approach will be used to design and implement all the different investigation phases.

Remedial Action at Sites DP105 and DD119 (TO240) (Back to Top)

Description of Task Order 240 (Back to Top)

  • Under a separate contract, the Air Force is planning to conduct a Remedial Investigation/Feasibility Study (RI/FS) at two sites, DP105 and DD119, on Hickam Air Force Base (AFB), Oahu, Hawaii. The purpose of the studies is to further investigate and delineate contamination uncovered at the sites during previous investigations, most recently the SI for Multiple AOCs project that was completed in July 2006. The work is being conducted in consultation with the State of Hawaii Department of Health (HDOH).

    At Site DP105, volatile organic compounds (VOCs), metals, petroleum hydrocarbons (TPH), and polynuclear aromatic hydrocarbons (PAHs) were found in the residual sump sludge at concentrations above HDOH Environmental Action Levels (EALs). The Air Force is concerned that the contaminated sludge remaining in the sump may have acted as a source of contaminants to the soil and groundwater beneath Building 2002.

    Additional RI was also recommended for Site DD119 because of the presence of metals, PAHs, pesticides, and polychlorinated biphenyls (PCBs) in debris pile soils at levels above applicable HDOH EALs. The concern exists that the contaminated debris pile may have acted as a source of contamination to the underlying site soil and groundwater. Based on the historical data, the debris does contain low-level contamination. Removal of the debris will allow access to the site for the additional investigation. It is anticipated that most of the debris will be disposed of on-island as non-hazardous waste.

  • Prior to the RI/FS at both sites, preliminary site work is necessary to access the areas of potential contamination. At Site DP105, removal of contaminated residual sludge from within a sump, and potentially, the removal of the sump itself, is necessary to access and investigate the area. At Site DD119, a large debris pile will be sorted as necessary and removed in order to access and investigate the ground beneath the pile.



  • The overall objective of any Remedial Action that may be performed at the sites would be to address areas of contamination that present unacceptable risks at the site, as noted in the RI/FS. If the RI/FS determines that contaminant concentrations are above acceptable ranges for applicable HDOH EALs or the associated risks, then remedial action may be necessary to perform actions presented in the FS to lower the risks and/or the onsite concentrations to acceptable ranges.

  • To achieve this objective, this project consists of the following primary tasks:


    • Sort and remove debris at Site DD119
    • Prepare project work plans for Sites DP105 and DD119 Remedial Actions
    • Perform remedial actions
    • Facilitate and support regulatory and community involvement
    • Transport and dispose of waste produced during remedial action
    • Collect environmental samples to confirm removal of contamination to acceptable levels
    • Prepare Remedial Action Report
    • Update the Administrative Record, ERPIMS, and GIS
    • Assist with update of the installation Management Action Plan

Sites CG104 and MY158 Remedial Investigation and Feasibility Study (TO395) (Back to Top)

Description of Task Order 395 (Back to Top)

  • Sites CG104 and MY158 include multiple former areas of concern (AOCs) that have been previously investigated by the Air Force under different projects. Site CG104 (Fuel Vapor Area/Auto Hobby Shop) is the former Area of Concern (AOC) EA04; Site MY158 (Kuntz Avenue Motor Pool) is the former AOC EA58. Earlier investigations indicated elevated levels of chlorinated solvents in groundwater at monitoring wells located at CG104 and elevated levels of petroleum hydrocarbons in soil and groundwater at MY158.

  • The overall objective of the proposed Remedial Investigation / Feasibility Study (RI/FS) is therefore to better delineate the nature and extent of the contamination at Sites CG104 and MY158 and to characterize the resultant risks to human health and the environment. If unacceptable risks are found to exist, remedial technologies that remove or mitigate the identified risks will be evaluated, and a remedial strategy will be selected and documented in a Record of Decision (ROD). Alternatively, if risks are found to be within acceptable limits (a risk range of 10-4 to 10-6 for cancer risk or less than one for non-cancer risk ) then the site will be closed and assigned No Further Response Action Planned (NFRAP) status.


  • To achieve this objective, this project consists of the following primary tasks:


    • Preparation of project work plans
    • Field investigations (including field screening, soil and groundwater sampling, monitoring well installation, and soil-gas sampling)
    • Onsite and offsite analysis of environmental samples
    • Data validation and tabulation
    • Data evaluation
    • Human health and environmental risk assessment
    • Identification of general response actions and applicable remedial technologies
    • Evaluation of remedial alternatives
    • Identification of preferred remedial action
    • Documentation of selected remedy
  • The current AFCEE QAPP Version is 4.0.01 (AFCEE, May 2005). The Installation-Wide QAPP (IWQAPP), Version 2.0, was finalized in November 2002 and meets the requirements of the AFCEE QAPP, Version 3.1 (AFCEE, August 2001). To meet the requirements of the AFCEE QAPP, Version 4.0.01, the Installation-Wide QAPP required an update. The update is to be developed as a programmatic document (as was the IWQAPP) to be used in conjunction with project specific QAPPs. This updated document establishes the quality assurance/quality control (QA/QC) protocols and procedures that govern sampling and analytical activities for projects at 15 ABW installations.

Site CD125 Remedial Investigation and Feasibility Study (TO586) (Back to Top)

Description of Task Order 586 (Back to Top)

  • Site CD125, the Debris Mound Containing Contaminated Soil, was formerly known as Area of Concern (AOC) EA25. It was initially identified as an AOC during a previous investigation because petroleum odor and apparent fuel-saturated gravel were noticed in one of the numerous soil and debris piles present in the area. The results indicated that polynuclear aromatic hydrocarbons (PAHs) were detected in the debris soil at concentrations above the applicable screening levels at the time of the investigation. In 2004, additional sampling was performed on the debris mound, as part of the Site Inspection (SI) for Multiple Areas of Concern project. Based on the results of the 2004 SI project, further investigation was recommended because PAHs, polychlorinated biphenyls (PCBs), and pesticides were detected in the debris soil at levels above the State of Hawaii Department of Health (HDOH) Environmental Action Levels (EALs) at the time of the investigation.

  • The overall objective of the proposed Remedial Investigation / Feasibility Study (RI/FS) is therefore to better delineate the nature and extent of the contamination at Site CD125 and to characterize the resultant risks to human health and the environment. If unacceptable risks are found to exist, remedial technologies that remove or mitigate the identified risks will be evaluated, and a remedial strategy will be selected and documented in a Record of Decision (ROD). Alternatively, if risks are found to be within acceptable limits (a risk range of 10-4 to 10-6 for cancer risk or less than one for non-cancer risk ) then the site will be closed and assigned No Further Response Action Planned (NFRAP) status.


  • To achieve this objective, this project consists of the following primary tasks:


    • Preparation of project work plans
    • Field investigations (including field screening, soil and groundwater sampling, monitoring well installation, and soil-gas sampling)
    • Onsite and offsite analysis of environmental samples
    • Data validation and tabulation
    • Data evaluation
    • Human health and environmental risk assessment
    • Identification of general response actions and applicable remedial technologies
    • Evaluation of remedial alternatives
    • Identification of preferred remedial action

Site MY111 Remedial Investigation and Feasibility Study (TO442) (Back to Top)

Description of Task Order 442 (Back to Top)

  • Site MY111 (Former Hawaii Air National Guard [HIANG] Motor Pool) has been previously investigated by the Air Force as Area of Concern (AOC) AF01. It was most recently studied as part of the TO97 Site Inspection (SI) for Multiple AOCs. The SI concluded that polychlorinated biphenyls (PCBs) and arsenic in soil, as well as dissolved arsenic in groundwater warranted further investigation. It has also been determined (as part of the Dynamic Work Plan [DWP] development) that the western portion of the site has not been adequately characterized during previous investigations.


  • The overall objective of the Remedial Investigation/Feasibility Study (RI/FS) is therefore to better delineate the nature and extent of the contamination at Site MY111 and to characterize the resultant risks to human health and the environment. If unacceptable risks are found to exist, remedial technologies that remove or mitigate the identified risks will be evaluated, and a remedial strategy will be selected and documented in a Record of Decision (ROD). Alternatively, if risks are found to be within acceptable limits (a risk range of 10-6 to 10-4 for cancer risk or a hazard quotient of less than one for non-cancer risk ) then the site will be closed and assigned No Further Response Action Planned (NFRAP) status.


  • To achieve this objective, this project consists of the following primary tasks:


    • Preparation of project work plans
    • Field investigations (including soil and groundwater sampling)
    • Analysis of environmental samples
    • Data validation and tabulation
    • Data evaluation
    • Human health and environmental risk assessment

  • If risks are determined to be unacceptable, then the following will conducted:


    • Identification of general response actions and applicable remedial technologies
    • Evaluation of remedial alternatives
    • Identification of preferred remedial action
    • Documentation of selected remedy

  • Field work will be conducted in two phases. To help streamline the RI/FS process, and in recognition of the uncertainties currently associated with the sources and nature and extent of contamination at the site, a Triad approach will be used to the extent possible. The Triad approach will use a combination of systematic project planning and dynamic work strategies to optimize data collection, accelerate project schedule, and minimize unnecessary re-mobilization of field teams at later stages of the project. Real-time data collection methods, promoted as part of the Triad approach, were evaluated as part of the DWP development. However, it was decided that standard laboratory methods would be preferable given the contaminants of interest at the site (PCBs and arsenic). To manage technical and administrative decision uncertainties, project stakeholders were involved at the work-planning stage, and the DWP was developed to include a flexible site investigation approach to ensure that the optimum amount of relevant data will be collected using the most efficient and cost-effective methods available.

Site (Landfill) LF05 Time Critical Removal Action, Hickam AFB (TO70 WERC) (Back to Top)

Description of Task Order 70 (Back to Top)

  • This Task Order (TO) addresses the activities supporting a Time Critical Removal Action (TCRA) for Landfill Site LF05 at Hickam Air Force Base (AFB), Oahu, Hawaii. Site LF05, previously known as the Tri-Services landfill, is located along the southern edge of Hickam AFB at the present site of the Mamala Bay Golf Course.
  • Refuse disposal and open burning reportedly took place at Site LF05 from about 1950 until 1965. When the facility was closed in 1965, the golf course was constructed over and around the landfill.
  • The overall goal of this project is to remove visible and loose blasting grit from the ground surface in the three areas adjacent to the Manuwai Canal and Ahua Lagoon. Removing this material will reduce the risk to site workers as well as prevent the material from entering the surface waters of the Manuwai Canal and Ahua Lagoon.
  • During the Remedial Investigation (DO 94), it was noted that elevated concentrations of arsenic, lead, and iron in surface soil tended to coincide with the presence of blasting grit that was previously spread over the ground surface in discrete locations across the site and surrounding golf course. Risk assessments using surface soil data have indicated that site worker exposure to this material is contributing to potential unacceptable risks. Additionally, blasting grit material was observed to be sloughing into the Manuwai Canal and Ahua Lagoon, which could potentially affect aquatic resources in these surface water bodies.
  • The TCRA remedial action objectives (RAO) for the blasting grit in Areas 03, 11, and 14 at Site LF05 are as follows:
    • Mitigate risks to golf course maintenance worker who may be exposed to elevated concentrations of metals in the blasting grit
    • Mitigate risk of blasting grit sloughing into the Manuwai Canal and the Ahua Lagoon and endangering aquatic habitats
    • Minimize potential for blasting grit to enter surface water via overland flow of storm water
  • To achieve the RAOs, the TCRA will involve removing the loose blasting grit that could slough into the canal and the lagoon. The remainder of the material will be addressed in the Remedial Action for Site LF05. The field scope of work for this project includes the following:
    • Removing the blasting grit, to the extent practical, from Areas 03, 11, and 14 on Mamala Bay Golf Course using a vacuum truck in an effort to prevent releases to surface water areas near the canal and lagoon.
    • Trimming down dense vegetation present along the bank of the Manuwai Canal at Area 03 to a level that allows for access and removal of blasting grit along the bank and allows the vegetation to re-grow once the TCRA has ended.
    • Collecting post-removal soil samples to document the site conditions once the TCRA is complete. Surface soil samples will be collected from the same areas where analytical samples were collected during the Feasibility Study and analyzed for arsenic, lead, and iron.
    • Providing erosion control where deemed necessary to prevent erosion of cleaned or restored areas.
    • Restoring selected areas where blasting grit was removed to golf course specifications and maintaining restored areas for a period of no less than two months. Water to sustain revegetation will be obtained from the existing golf course sprinkler system at no extra cost to this contract.

Runway 8L Sites SS11, ST26, OT02, and LF14 Interim Remedial Action, Hickam AFB (DO106) (Back to Top)

Description of Delivery Order 106 (Back to Top)

  • This project implements interim removal actions (IRAs) at four Runway 8L Sites at Hickam Air Force Base (AFB), Hawaii. Engineering Evaluation/Cost Analyses (EE/CAs) and Action Memorandums (AMs) have previously been prepared and remedies selected for the four sites. A brief description of each site and the selected remedy described in the AM is as follows:
    • Site SS11 consists of two subareas of concern: the SS11 South/Air Mobility Command (AMC) Ramp Area and Fuels Area 5. Jet fuel releases, as well as other petroleum, oils, and lubricants (POL) usage, have resulted in free-phase and dissolved petroleum contamination in soil and groundwater. Fuels Area 5 contains residual contamination from historic aviation gas (AVGAS) releases from underground storage tanks. Residual AVGAS contamination at Fuels Area 5 has resulted in elevated lead concentrations in groundwater. The selected remedies are:
    • SS11 South/AMC Ramp Area: A bioslurper will be operated with wells placed in the areas with greatest apparent free product (this DO comprises bioslurper pilot testing only and design of the full-scale bioslurper system); groundwater will be monitored annually to evaluate natural attenuation of petroleum constituents (this DO comprises one round of groundwater monitoring); institutional controls will be utilized to control future exposure to petroleum-impacted soil and groundwater.
    • Fuels Area 5: Groundwater will be monitored every other year to evaluate the migration and attenuation of dissolved lead constituents (this DO comprises one round of groundwater monitoring); institutional controls will be utilized to control future exposure to contaminated groundwater.
    • Site ST26 consists of the Kuntz Pipeline, an abandoned AVGAS and jet fuel pipeline, and associated valve pits. Levels of detected petroleum constituents are below action levels with the exception of contamination detected at specific valve pits. It has been determined, however, that the source of contamination is not the pipeline. The selected remedy for the pipeline is:
    • Closure in place, with removal of three valve pits and associated steel piping and concrete. Limited confirmation sampling will be performed as necessary during valve pit removal.
    • Site OT02 South consists of a former waste disposal leachfield that has vinyl chloride in groundwater at concentrations above action levels which may pose a risk to human and ecological receptors in the nearby Kumumauu Canal. The selected remedy for the site is:
    • Institutional controls with long-term groundwater monitoring. Two new monitoring wells will be installed between the vinyl chloride plume and the Kumumauu Canal and monitored annually for five years to evaluate the migration of vinyl chloride toward the canal (this DO comprises one round of groundwater monitoring).
    • Site LF14 consists of a 30-acre, former landfill used for disposal of building and road demolition debris, excess soil, and green waste. Surface and subsurface soils exhibit POL constituents and elevated concentrations of polynuclear aromatic hydrocarbons (PAHs); residual concentrations of pesticides were detected in groundwater. The selected remedy for the site is:
    • Institutional controls with long-term groundwater monitoring. A fence will be constructed around a portion of the site and two new monitoring wells will be installed. Groundwater will monitored once every three years to evaluate the migration and attenuation of PAHs and pesticides (this DO comprises one round of groundwater monitoring).
  • This project consists of the following primary activities:

    • Task 1: Preparation of Project Planning Documents
    • Task 2: Project Management, Support and Administration
    • Task 3: Administrative Record Support
    • Task 4: Community Relations
    • Task 5: Regulatory Interaction
    • Task 6: Field Investigation
    • Task 7: Site Work, Temporary Facilities
    • Task 8: Off-Site Laboratory Sample Analysis
    • Task 10: Analytical Support, Sample Management, and Data Validation
    • Task 11: Data Evaluation
    • Task 13: Document Preparation
    • Task 15: Treatability Studies

Description of Task Orders 23 and 105 (Back to Top)

  • This project is based on the results of an Engineering Evaluation/Cost Analysis (EE/CA) performed as part of a previous project (DO 55) and implements Interim Removal Actions (IRAs) for Sites SS13 and Site SS15 as identified in the Final EE/CA and Action Memoranda for each site. As documented in the EE/CAs and Action Memoranda, actual or threatened releases of hazardous substances from these sites could present a potential endangerment to public health or welfare and/or the environment. The proposed IRA activities seek to address these concerns. TO 105 is the follow-on to the project and presents reports on the continued groundwater monitoring.

    Site SS13
  • IRA objectives for Site SS13 include site characterization, continued groundwater monitoring, and planning for reasonably anticipated future land use.
  • The following tasks are planned:
    • Drilling, sampling and analysis to identify the nature and extent of subsurface contamination.
    • Abandonment of monitoring wells and two site utilities.
    • Continued MNA groundwater monitoring, coupled with Institutional Controls.
    • Preparation of technical planning document addenda and reports, contractual management reports, and participation in meetings.


    Site SS15
  • IRA objectives for Site SS15 include further site characterization to delineate LNAPL and dissolved-phase constituents in groundwater beneath the Site, LNAPL removal to the greatest extent practicable, continued monitored natural attenuation (MNA) groundwater monitoring, and planning for reasonably anticipated future land use.
  • The following tasks are planned:
    • Drilling, sampling, and analysis to identify the nature and extent of subsurface the LNAPL plume and construction of new monitoring wells for free-product recovery and MNA groundwater monitoring.
    • Abandonment of monitoring wells.
    • Removal of LNAPL using a mobile multi-phase extraction (MPX) system, passive skimming, or a vacuum truck removal system.
    • Preparation of site characterization and well abandonment reports.
    • Preparation of technical planning document addenda and reports, contractual management reports, and participation in meetings.
    • Continued MNA groundwater monitoring coupled with Institutional Controls.

Sites SS024 (Reef Taxiway) and Former Mess Hall Area, Remedial Invesgitation (RI), Feasibility Study (FS), and Record of Decision (ROD), Hickam AFB (TO 52) (Back to Top)

Description of Task Order 52 (Back to Top)

  • Historical operations at Site SS024 (Reef Taxiway) and the Former Mess Hall area involving the use and potential releases of chemicals of concern dated back to the 1940s. Based on the results of previous site investigations, Site SS024 (Reef Taxiway) has soil and groundwater contaminated with metals, while the FMH area has soil contaminated with dioxins and lead. The results of these investigations also indicate that further investigation of Site SS024 (Reef Taxiway) and the FMH area is warranted based on remaining uncertainties at the sites.
  • To help streamline the investigation processes, and in recognition of the uncertainties currently associated with the sources, nature, and extent of contamination at both sites, the Triad approach is being used to design and implement the RI/FS and the SI.
  • Specific tasks to be performed under this project include the following work activities:
    • Preparation of Project Planning Documents
    • Provide technical support on the Hickam Restoration Program IMF website
    • Conduct an ERPIMS audit of the Hickam POL site data
    • Support Community Relations Program and RAB activities at Hickam AFB
    • Provide support for regulatory interaction
