PetroFix Chosen as Most Cost-Effective Approach

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.

This case study reviews a PetroFix application to address hydrocarbon contaminants at the former Buxton Naval Auxiliary Air Station, located within the Cape Hatteras National Park in the Outerbanks region of North Carolina. 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.
