A list of Overseas projects:

  • PCB Remediation Oversight for a Major Confidential Client, OISO, Japan

A major corporation retained ESI for review and oversight of remedial activities at a manufacturing facility near Tokyo.  Remedial actions and review activities focused on PCB soil contamination and remediation by excavation and sequestering in a newly constructed underground facility.

 

  • Level B Removal of Toxic Sludge from a Cave on Hakosaki Fuel Terminal, Azumi Island, Kanagawa, Japan

ESI removed a 30 cm thick layer of toxic sludge that included PCBs, petroleum hydrocarbons, and heavy metals from a cave floor at a fuel depot island used by the U.S. Naval base in Yakosuka, Japan.  The project was performed using supplied air under permit-restricted confined space conditions.  ESI trained Japanese subcontractors for confined space, designed and supplied ventilation, protective clothing, and rescue and breathing equipment.  During the initial inspection entry, ESI installed five tubes into the cave to monitor the LEL and the concentration of toxic gases in each defined zone of the cave.  Japanese pump trucks were barged to and from the island on a daily basis.  The standard size truck could not be used due to barge size limitations; so two pump trucks were used in series to create enough vacuum to extract the sludge.  After the sludge and sludge-contaminated sand was removed by suction, ESI chiseled the cave walls to remove stained rock.

 

  • Remediation of Subsurface Plume Using Multiphase Extraction and Catalytic Oxidizer, Yokota Air Base, Japan

ESI successfully and simultaneously performed an investigation and a remedial action during a three-month field effort at Yokota Air Base.  The client’s property was contaminated with 18,000 gallons of jet fuel that was released from a leaking fuel distribution system.  ESI installed a multiphase extraction (MPX) system to recover the jet fuel using five existing 2” wells and five new wells installed by ESI.  A pre-wired, pre-plumbed and pre-tested packaged MPX unit was placed in an ocean-shipping container and transported to the site.  A built-in telemetry unit was configured to immediately call for service when the system shut off.  ESI recovered over 15,000 gallons of jet fuel within the first two years of operation.

 

  • Shallow Aquifer Intercept and Natural Soil Washing in Okinawa

ESI was called to intercept and contain diesel fuel that had spilled and was seeping out of an embankment into a river floodplain.  By taking advantage of the aquifer slope, we were able to design and construct a subsurface intercept drain within a 60-degree embankment.  The subsurface intercept draining system utilized gravity flow to drain the collected diesel into a collection tank.  Since the site was away from power sources, near housing areas and on a floodplain, this system design allowed for a quiet, low maintenance washing of the soil.  Okinawa is known for large amounts of rainfall.  Because ESI designed an effective subsurface drain, we were able to reduce the contact with non-contaminated  rainwater using this system.
