Project Owner: U.S. Army Corps of Engineers
Project Description: HIES conducted confirmation soil sampling and a geophysical survey as part of a Preliminary Site Investigation at the Archery Range Site located within Wheeler Army Airfield, Hawaii. The objective of the Preliminary Site Investigation was to determine if any chemical constituents were released from the drums found at the site, and if any magnetic anomalies were present that could represent additional drums in the area. A total of 29 surface drums and 29 subsurface metal objects were located and mapped. In addition to the drums other metallic objects including expended ammunition and cartridge casings, engines and vehicle parts, as well as concrete, asphalt and transite piping were observed and mapped. HIES collected a total of 24 soil samples, and laboratory analytical results indicate that the site had been impacted by TPH, SVOCs, and lead above DOH SALs. Pesticides, including DDD, DDE, and DDT and VOCs, were also detected, but were detected at concentrations below DOH SALs. Based on the Preliminary Site Investigation, HIES performed an Additional Site Investigation and Interim Removal Action. HIES delineated the vertical and horizontal extent of contamination and removed the drums and debris located in the Preliminary Site Investigation. By the end of the removal action, approximately 200 drums, 10 tons of asbestos pipe, 20 tons of debris, 62 tons of non-RCRA petroleum impacted soil and 18 tons of RCRA lead impacted soil were removed from the site and disposed of properly. |

Emergency Spill Response, Former Lau Farms, Inc., Aiea, Hawaii
Project Owner: Kamehameha Schools/Bernice Pauahi Bishop Estates
Project Description: HIES conducted a spill response at the former Lau Farms, Inc., 98‑114 Kamehameha Highway, Aiea, Hawaii. The objective of the project was to respond to a diesel fuel spill at the Site that occurred while Lau Farms personnel attempted to move an old 55-gallon open-head drum. A small hole at the end of the drum was noticed and Lau Farm personnel witnessed diesel fuel leaking from it. The drum was secured so no further product would be released onto the site. HIES personnel observed the drum on its side and confirmed it to contain diesel fuel. It was also noticed that the spill contained various mixes of fertilizers. An emergency spill response team was assembled, which included personnel from Pacific Commercial Services, LLC [PCS], to immediately clean up the spilled diesel fuel and fertilizer mixture. It was estimated that approximately 10 to 15 gallons had spilled. The damaged drum was overpacked in an 85-gallon, DOT-approved open-head drum for transport and disposal. Cat litter was used to absorb the diesel fuel and fertilizer mixture from the stained asphalt driveway and shoveled with plastic shovels into two 55-gallon, DOT-approved open-head drums. A solution containing Simple Green was applied to the area of the spill to further clean the asphalt surface and more cat litter was applied to absorb any residual liquid. The absorbent material was shoveled into the remaining drum. |

Improve Family Housing, Kadena Air Force Base, Okinawa, Japan
Project Owner: U.S. Air Force
Project Description: On behalf of Rim Architects, HIES conducted a hazardous materials survey of one hundred 162+Ph7 housing units located in on and near Kadena AFB in Okinawa, Japan. The 162+Ph7 units correspond with four Phases of the Improve Family Housing project that HIES has been subcontracted to be a part of.
HIES provided certified asbestos and lead inspectors to conduct the survey and for report preparation.
This survey was performed in order to obtain information related to hazardous materials in the various units planned for renovation prior to the upcoming renovation of the buildings. The work was conducted in general accordance with applicable United States EPA guidelines and the JEGS.
The 162+Ph7 units inspected were divided into distinct unit types based on the floor plan type and neighborhood .Different units were sampled during different phases.
Bulk samples of identifiable suspect building materials were collected from homogeneous areas within the buildings. Samples from each homogenous area were analyzed for asbestos content utilizing PLM in accordance with EPA Method 600R-93/116. The detection limit of the PLM method for asbestos identification is 1% by volume.
A total of 129 building material samples were reported to be ACM (containing greater than 1% asbestos) following the initial PLM laboratory analysis. Several samples with asbestos percentages greater than 1% but less than 6% were reanalyzed using the point counting method. All of the samples retested using the point counting method were still found to contain more than 1% asbestos and therefore are still classified as ACM.
All of confirmed positive ACM identified in the buildings sampled were in good condition at the time of the survey.
