Brice performed a release investigation, remedial action, and infrastructure removal at 10 sites for the Federal Aviation Administration in Bethel, Alaska. Three sites were located in the City of Bethel, and seven sites were located two miles southeast of the city across the Kuskokwim Airport near the former Bethel Airport. The project objectives were to Read More

Remedial Investigation and Landfarming, Gulkana, Alaska
Brice performed a remedial investigation (RI) and remedial action (RA) at the Federal Aviation Administration (FAA) Gulkana Station at the Gulkana Airport in Alaska. The primary contaminant sources and suspected release mechanisms are leaks and spills of petroleum hydrocarbons from fuel storage and distribution systems (i.e. tanks and piping) and from drums. Brice implemented land Read More
Remediation on Wake Island Airfield, Wake Island Atoll
Brice performed a remedial action at Sites OT013 (Scrap Metal Pile No. 2 and Burn Area) and ZZ011 (Burn Area No. 2) on Wake Island Airfield, Wake Island Atoll. The project objectives included removal of polychlorinated biphenyls (PCB)-contaminated soil at OT013, excavation of dioxin-contaminated soil at ZZ011, confirmation soil sampling, and transport and disposal of Read More
Remediation Study and Product Bail-Down Testing, Cold Bay, Alaska
Brice performed a pilot study to evaluate in-situ chemical oxidation (ISCO) as a remedial alternative and product bail-down testing at a former FAA Station in Cold Bay. Once the pilot study test area layout was staked, we collected pre-treatment soil samples to determine existing petroleum hydrocarbon concentrations. Soil cores were screened using a photoionization detector Read More
Bench-Scale Pilot Study and Feasibility Study, Puntilla Lake, Alaska
At Puntilla Lake, Brice performed a bench-scale pilot study to evaluate in-situ smoldering, known as Self-Sustaining Treatment for Active Remediation (STAR) and ISCO as remedial alternatives; results were presented in a feasibility study for this petroleum-contaminated site. We advanced test pits using an excavator in a heavily impacted area beneath former fuel tanks to collect Read More
Remedial Action and Demolition, Sisters Island, Alaska
Brice performed demolition, debris removal, and a removal action at a Former Dump Area on Sisters Island, Alaska. We first removed approximately 160 cubic yards (cy) of inert debris to 7 feet bgs and included liner, plastic, tires, household trash, metal debris, cable, glass, a large boat anchor, a welder, a compressor, a 500-gallon empty Read More
Mean Hydraulic Gradient Study, Kodiak Island, Alaska
Brice completed a mean hydraulic gradient study and non-aqueous phase liquid (NAPL) characterization at the Airport Staging Area (ASA) and Fire Training Pit (FTP) Formerly Used Defense Site (FUDS) in Kodiak, Alaska. The source of contamination was an FTP used by military firefighting personnel in practice simulations. A variety of flammable liquids were placed into Read More
Infrastructure Removal, Chirikof Island, Alaska
Brice performed a two-phase project at 10 areas of concern (AOC) at the Radio Range Facility on Chirikof Island, Alaska. Phase 1 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; and to determine the Read More
Environmental Services, Multiple Locations, Western Alaska
Brice executed environmental services at three Federal Scout Armories located in western Alaska. All three sites are accessible only by air and sea. To execute the project, we prepared site-specific work plans including UFP-QAPP to establish DQOs; a Sampling Analysis Plan; Project Management Plan and project schedule; and Community Relations, Waste Management, Contractor Quality Control, Read More
VHF System Removal, North Dutch Island, Alaska
Brice performed an interim removal action (IRA) to excavate petroleum-impacted soil and lead-impacted soil from several areas of concern (AOCs), and restored the site to facilitate a No Further Action/Cleanup Complete Determination. We excavated and disposed of approximately 256 cubic yards of petroleum- and lead-contaminated soil offsite. Confirmation soil samples collected from the final excavation Read More
