Conti Federal Awarded $1.57M Contract for Remediation of Burnt Fly Bog Superfund Site in New Jersey

Conti Federal Services, a leading U.S. government construction and engineering firm specializing in environmental remediation, has been awarded a task order contract for the remediation of the Burnt Fly Bog Superfund Site, Westerly Wetlands OU3 in New Jersey.

The contract was awarded through the EPA Remediation Environmental Services (RES) Suite of the Remedial Acquisition Framework for the fixed amount of $1,568,533.54. Located in Monmouth County, New Jersey, the Burnt Fly Bog Westerly Westland OU3 area consists of approximately 60 acres of wetlands contaminated with lead, polychlorinated biphenyl (PCB), and total petroleum hydrocarbon (TPH).

The Burnt Fly Bog Superfund Site project has multiple objectives including addressing the remedial action objectives (RAOs) as defined by the Record of Decision to:

  • Reduce exposures to PCBs and lead in the soil at levels exceeding state and federal soil cleanup criteria in the Westerly Wetlands, while minimizing the extent of wetlands to be excavated.
  • Reduce/control release of contaminants in sediment into surface waters during storm events.
  • Reduce/control exposure to PCBs and lead in soil to ecological receptors.
  • Restore the Westerly Wetlands to a productive ecosystem.

Contamination of the site took place during the 1950s and 1960s from the nearby Imperial Oil Company and Champion Chemical facility. Hazardous materials resulting from recycled waste oil operations were directly dumped, resulting in surface water and soil contamination. In 2012, Conti Federal had conducted remediation efforts at Imperial Oil as well, with a large-scale soil excavation and groundwater remediation including hydraulic containment of the site and large-scale load out and disposal of 180,000 cubic yards of excavated material.

The work on the Imperial Oil site, which earned Project of the Year in the Industrial/Manufacturing category for the New York region from Engineering News-Record, provides the Conti Federal team with extensive experience in understanding and remediating this specific geographic area and its unique attributes.

Conti Federal’s proposed and accepted solution includes remediating the sediment contamination at the Westerly Wetlands. In accordance with EPA-approved 2020 In Situ Soil Amendment Treatability Pilot Study (ISSA-TPS), the remedy consists of two applications of Apatite II amendment, mixing it into the sediment, and covering the amendment with degradable netting to ensure it remains in place. The treatment areas include two “hot spots,” one in the center of the Westerly Wetlands and the second in the eastern area towards the Uplands capped portion of the site.

The selected remedy expects that a layer of organic detritus (known as “humification”), will accumulate over time, forming an increasingly natural protective barrier over the contaminated soil and be monitored over time. The selected remedy will also preserve the existing wetland system while monitoring the surface water and sediment conditions in Burnt Fly Brook to ensure that on-site contamination does not reach the Brook.

“This type of work has great significance to us at Conti Federal,” says Laura Tobin, Vice President, Environmental Business Line Leader. “We recognize that this is a service to our community and impacts the future greatly. By successfully remediating this Superfund site, we are protecting human health as well as the environment.”
