    DO56: Site Characterization of Various Sites, Hickam Air Force Base, Oahu, Hawaii

    Description of Delivery Order 56 (Back to Top)

    • This Delivery Order (DO) addresses site characterization and closure at five sites (two fuel spill sites and three former underground storage tank (UST) sites) at Hickam AFB which have been subject to releases of petroleum product. The five sites that comprise this DO are:
      • Challenger Loop (Fuel Spill Site)-The site is adjacent to a residential area where two pipeline breaks, accompanied by fuel leaks of undetermined volumes, occurred in 1994 or 1995, and 1998.
      • Air Mobility Command (AMC) Stripper Pit (Fuel Spill Site)-The site is located near the fire station and flight line where jet fuel overflowed the stripper pit and spilled over the adjacent soil surface in 1998.
      • Building 1815 (Former UST Site)-The site is the location of a former 920-gallon diesel UST located adjacent to Building 1815 (currently a dormitory).
      • Site 2170B (Former UST Site)-The site is the location of a former 2,000-gallon reclaimed jet fuel (JP8) UST located north of Building 2170 in Fuel Area 11.
      • Building 1035 (Former UST Site)-The site is the location of a former 500-gallon waste oil UST located adjacent to Building 1035 (currently an active military gas station).
    • The overall objective of this project is to perform additional site characterization and obtain regulatory closure as feasible, or recommend follow-on actions as warranted. To achieve these objectives, this project consists of the following primary activities:
      • Preparation of draft and final planning documents
      • Project management, subcontract support, and administration and status reporting
      • Field investigation
      • Laboratory analyses, database management, and data validation

    TO 81: Building 1815 Remedial Investigation Former Underground Storage Tank Site, Hickam Air Force Base, Oahu, Hawaii

    Description of Task Order 81 (Back to Top)

    • The Building 1815 UST site historically contained a 920-gallon underground storage tank (UST) used to supply a hot water heater in the building. A release of heating oil/diesel was detected during the UST removal and a subsequent Site Investigation. Up to two feet of LNAPL was observed floating on top of groundwater in temporary monitoring wells installed at the site. The site lithology generally consists of clay over silty sand and clay with limestone fragments. Tuff was not encountered above 15 feet bgs during the 2000 investigation. Groundwater was encountered at approximately 8.5 feet bgs. Building 1815 is currently being demolished. Once the debris is removed, the site should be leveled which will provide excellent access.
    • The overall objective of this project is to perform a remedial investigation at Building 1815 to determine the extent of contamination from a former UST and to develop recommendations for follow on actions. The primary objectives of the RI at Building 1815 include the following:
      • Estimate the nature and extent of the petroleum contaminations
      • Develop a comprehensive conceptual site model
      • Assess the potential risks to human health and the environment
      • Conduct a remedial alternatives analysis to identify and evaluate the implementability, effectiveness, and cost of various remedial actions
      • Conduct a treatability study, if required to obtain additional data to support the selected remedy
    • To achieve the above objectives, the following scope of work is planned:
      • Site reconnaissance (including historical records review)
      • Data gap analysis (Project Work Plan)
      • Soil gas, soil, and groundwater sample collection to determine the extent of contamination
      • Semi-annual groundwater monitoring for approximately two years
      • Data validation and evaluation
      • A treatability study, if required, to determine the practicability of free product removal
      • Develop recommendations for follow-on actions
      • Prepare an Environmental Hazard Management Plan, if required
      • Attend meetings with the Air Force, Hawaii Department of Health, AFCEE, and general public; and provide meeting support

This project also addresses an inactive UST at Building 1050, for which no previous closure activities have been conducted. This TO includes removal and permanent closure of the inactive tank.
  • The following five sites make up this TO:
    • Building 484 (Heating-Oil UST)-UST closed-in-place in 1997 by Engineering Sciences Pacific, Inc. (ESP), who performed the UST investigation and prepared a UST closure report for the Site.
    • Building 2156 (Reclaimed JP-8 UST)-2,000-gallon tank formerly used to store jet propulsion (JP) fuel Type 8 (JP-8), reclaimed from an adjacent oil/water separator and adjacent fuel pipelines located at Building 2156. Removed in 1997; Jacobs Engineering Group Inc. (Jacobs) performed a UST investigation and prepared a UST closure report at that time.
    • Building 2045 (Diesel UST)-Former 550-gallon diesel tank; removed in 1997. Jacobs performed a UST investigation and prepared a UST closure report.
    • Building 1050 (Diesel UST)-Inactive 2,500-gallon diesel fuel UST.

  • The overall objective of this project is to perform additional site characterization and obtain regulatory closure as feasible, or recommend follow-on actions as warranted. To achieve these objectives, this project consists of the following primary activities:
    • Preparation of draft and final planning documents
    • Project management, subcontract support, and administration and status reporting
    • Field investigation
