Client: Federal Aviation Administration
Location: Chirikof Island, Alaska
Completion Year: 2017
Scope of Work:
- Remedial investigation
- ACM surveys
- Debris removal
- Sampling and analysis
Brice performed a remedial investigation and limited debris removal from 10 areas of concern at the Radio Range Facility on Chirikof Island, Alaska. The project objectives were to identify any contaminated infrastructure or with the potential to contaminate the environment with hydrocarbons, polychlorinated biphenyls (PCBs), metals, or asbestos-containing materials (ACM); any associated safety hazard that may require management under the Resource Conservation and Recovery Act (RCRA); and determine the magnitude and extent of soil and water contamination.
Brice removed 15 batteries and two empty broken transformers. Ten hardened paint cans, 15 cylinders deemed RCRA empty, and approximately one ton of lead cable were also removed. We performed ACM surveys at each former building location, and ACM samples and bulk debris samples were collected from the building debris. We collected soil samples at locations most likely to be contaminated based on the presence of contaminated debris and/or visual or olfactory indications of contamination.
Analytical results indicated that the remaining debris at Chirikof Island is not contaminated with ACM, PCBs, or leachable lead, and is therefore not an inherent danger to human health or the environment. We recommended that U.S. Fish and Wildlife Service and FAA conclude what infrastructure should remain or be removed to satisfy stakeholder objectives. We also recommended further removal actions from specific areas to achieve cleanup levels.
