This case study reviews the former Buxton Naval Auxiliary Air Station located on the North Carolina Outer Banks. The US Navy utilized the site as a submarine monitoring station from 1956 to 1982. The US Coast Guard (USCG) acquired the facility after 1982 and used the site as a logistical, communication, medical, and supply support center. The site contains four areas of investigation which encompass a total area of approximately 50,000 square feet. Since 2011, the site has been undergoing long-term monitoring. Although the monitoring shows natural attenuation occurring, persistent exceedances of petroleum hydrocarbons warranted additional remediation efforts. In the process of a thorough evaluation of viable remedies, the responsible party specified PetroFix micron-scale, liquid-carbon amendment to be applied to quickly and effectively address the contaminant levels and achieve their site goals of NFA.


Case study highlights:

  • PetroFix Remediation Fluid was chosen because it is specifically designed to treat PHC plumes stemming from bulk storage, gas station, and UST spills.
  • The responsible party plans on closely monitoring the site and is using PetroFix on other CERCLA/RCRA-funded sites to accelerate site closure.
  • The crew was able to make real-time adjustments to injection volumes, pressure, tooling, and locations to accomplish the distribution goals.
