Cameron-Cole was the remediation contractor for the cleanup of a  a challenging petroleum contamination site at the Pensacola International Airport (PNS).  The site involved multiple documented releases from various current and former tenants of the airport’s fuel farm including the former Eastern Airlines, Pensacola Aeromotive and Pensacola Aviation. Cameron-Cole completed assessment activities to define the horizontal and vertical extent of soil and groundwater contamination at the fuel farm which was located within the secured Airport Operations Area. Depth to groundwater at the site was documented to range from 60 feet (ft) to 90 ft below land surface (bls), and the vertical extent of contamination was defined at 105 feet bls. The assessment identified a large plume of jet fuel that had migrated off-site to the south beneath a roadway, impacting a federal Army Reserve facility. Phase separated hydrocarbon accumulation within several on-site wells was documented to be in excess of 8 ft, and the estimated volume of free product prior to remediation was 53,000 gallons. Cameron-Cole completed pilot testing and developed a Remedial Action Plan (RAP) specifying the use of an air sparging and soil vapor extraction (AS/SVE) system to treat the dissolved hydrocarbon plume. The AS/SVE system components were housed in two separate buildings located on the airport property and a third building, housing a manifold system, was located on the Army Reserve property. After the first year of operation, the area of free product had been reduced by approximately 91% and the area of dissolved phase contamination (approximately 61,575 square feet) had been reduced by 65%. Free product, originally present in nine groundwater monitoring wells located on both properties, was reduced to a single well. After approximately two years of system operation, groundwater contamination had been completely remediated at the Army Reserve property and the hydrocarbon plume was reduced to the immediate source area. Cameron-Cole completed supplemental assessment to evaluate the extent of adsorbed contamination remaining in the smear zone and the occurrence of free product, which was limited to a few inches affecting a single source area monitoring well. 

Throughout its long-term involvement with the the airport, Cameron-Cole has successfully met the challenging conditions presented by the site and closed three other petroleum releases reported at the airport fuel farm.
