PCR Environmental, Inc. was retained to evaluate environmental impacts caused by the August 1997, crash of Korean Air Flight 801 in a remote area on Guam. The project involved interaction with emergency response officials from the local and federal government, regulatory agencies, attorneys, and insurance company representatives. In order to comprehensively address environmental impacts caused by Jet fuel, hydraulic fluids, and other chemical releases, PCR prepared Health & Safety, Site Investigation and Remediation Plans. After procurement of subcontractors and other outside services, extensive soil and water sampling of the 20 acres impact zone was completed. More than 200 samples were analyzed and interpreted to perform ecological and human health risk assessments, and evaluation of remedial action alternatives.
PCR designed and installed a self-contained gasoline vapor extraction system for soil and ground-water remediation at a service station in Kolonia, Pohnpei. Due to the remoteness of the site, a system was designed that incorporated wind energy to propel a extraction fan. Subsequent air sampling has indicated that the system is working as designed, with limited maintenance requirements.
PCR personnel managed a $420,000 Emergency Action Site Investigation at a 44-acre construction site and 15 associated offsite disposal areas. The construction project was halted by Guam EPA after high arsenic levels were detected on the property. The fast-track project encompassed coordination of the project team from four different offices, procurement and contracting of subcontractors, soil gas survey, geophysical survey, surface and subsurface soil sampling, environmental testing, preparation of health risk assessments and preparation of a comprehensive SI Report.
