Problems/Comments

Groundwater Zone 3 (OT29). Estimated 500,000 barrels (contents unknown) and miscellaneous solid waste disposal area from the 1950s to the 1970s. Approximately 200 drums were removed in 1984, and 26,000 drums were removed in 1991. In 1997 and 1998, limited removal actions, re-contouring, and capping activities were conducted at North Barrel Bluffs. An Operation, Monitoring, and Maintenance manual has been developed for both bluff sites. A three party agreement was reached between EPA, ADEC, and the Air Force for the bluff sites and signed by the agencies in 1996. An interim action record of decision was signed in 1996, and a final record of decision was signed in 2000. The Final Record of Decision states that based on current site conditions and the successful implementation of interim remedial actions, USAF, ADEC, and USEPA have selected a plan of institutional controls (site-access and land-use restrictions), bluff inspection and maintenance, continued operation of the water-treatment system, and continued monitoring, with no further remedial action planned, as the final action for the North and South Bluff.

6/30/1989 Update or Other Action (Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). CH2M Hill stage 2 workplan to assess 4 sites: North and South Barrel Dump Sites; Naknek River; and Eskimo Creek seeps. Remedial investigation and feasibility study occur in parallel. No Longer Assigned
6/30/1989 Update or Other Action (Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). CH2M Hill QA/QC plan for various King Salmon Airport sites; the sites include the Eskimo Creek oil seep, North Barrel Dump, Naknek River seep, and the South Barrel Dump. A total of 17 sites were addressed by this QA/QC plan. No Longer Assigned
8/29/1989 Update or Other Action (Old R:Base Action Code = SI - Site Investigation). CH2M Hill site investigation. The airport was originally constructed in the early 1940s to support the war effort. The airport was turned over to the State of Alaska in 1959. The State continues to operate the site with the Air Force as the major tenant. A White Alice site was activated in 1957. It was deactivated in 1979 and replaced with an Alascom Satellite earth terminal. Only a small portion of the site is owned by the State. The majority is on military land. In 1980, 340 military personnel resided at King Salmon Airport. The north and south barrel dump site, Eskimon Creek Seep and Naknek River seep sites were tested for over 146 constituents of concern. Of these, 39 potential contaminants of concern were identified. High concentrations of TPH were identified in shallow wells and soils at this site. Floating product (>1 foot) was identified at the Eskimo Creek Seepage Site. Lead and petroleum hydrocarbon contamination levels at this site pose a threat to fish and wildlife (page 126). No immediate environmental threat was identified at the Naknek River Seep (page 126). Both the north and south dump sites could pose a threat to fauna since the detection limits used in analyses were greater than the chronic aquatic organism toxicity. Remediation, based on stage 2 sampling, at both barrel dump sites could include: no action; restricting site access; preventing the migration of contaminants. Containment preferred remediation route. The Naknek River and Eskimo Creek seeps will receive further sampling to identify a specific remediation response. In general, based on further sampling results, the alternatives are: no action, which will not occur based on preliminary site investigation; recovery of floating product; treatment of shallow groundwater; excavation of contaminated soils; restrict site access; containment.

Land Use Plan / Maps / Base Master Plan The USAF will modify the General Plan, 611th Air Support Group (ASG), Remote Alaska (hereafter referred to as the General Plan) and appropriate land records (i.e., deeds) to include approved institutional controls, which restrict future installation of drinking-water wells and soil excavation at both sites.

Description Details
Groundwater Monitoring Residential wells near the bluffs have been sampled for potential contaminants several times since 1994. No contaminants have been detected; consequently, residential wells will no longer be sampled. Instead a more comprehensive system of sentry wells has been installed and will be sampled as delineated in the revised monitoring plan (Bristol/OASIS, 1999a). Groundwater and surface-water monitoring at the bluffs will continue on an annual basis following procedures outlined in the revised monitoring plan (Bristol/OASIS, 1999a).
