We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.

Problems/Comments

Elevated levels of volatile organic compounds (VOC), semi-volatile organic compounds (SVOC), and gasoline range (GRO), diesel range (DRO), and residual range organics (RRO) were detected in soil samples collected from a drum cache area where approximately 120 55-gallon drums remain on-site. Environmental Protection Agency (EPA) Superfund Technical Assessment & Response Team Contracts (START) program 3/99 Site Investigation found petroleum contamination has not migrated to adjacent lagoons and subsistence use areas. Also performed area wide well-search. Drinking water in Kotzebue is obtained from Devils and Vortac Lakes, approximately 3 miles inland. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) ID# 0002011385. GRO was found in DD02SS at 420 milligrams per kilogram (mg/kg). DRO ranged from 13,000 mg/kg to 71,000 mg/kg and residual range organics ranged from 38,000 to 160,000 mg/kg.

3/2/1999 Update or Other Action EPA START Site Characterization. Kotzebue Drum Dump (KDD) -CERCLIS ID AK0002011385, Latitude: 69 52' 25" Longitude:162 37' 10" West legal description Section 16, Township 17 North, Range 18 West. Site Inspection Report TDD: 97-09-0011 Contract 68-W6-0008 February 1999 (received on March 9, 1999) Region 10 Superfund Technical Assessment and Response Team (START). The KDD is located south of Ralph Wein Memorial Airport (referred to as the Kotzebue Airport), which is south of the City of Kotzebue and adjacent to the city's facilitative sewage lagoons. This site is located on a strip of land bordered by Kotzebue Sound on the west and a saltwater lagoon to the east (see also CS reckey# 1999320110401 Kotzebue Drum Dump). The KDD is a stockpile of 150 rusted or otherwise comprimised 55-gallon drums scattered over approximately one acre of land. The site is not fenced or gated. Approximately 5% of the drums are labeled with either United States Air Force or United States Navy markings. The drums labeled United States Air Force are also labeled Mona Lisa Project. The Mona Lisa Project was an Air Force effort to transport supplies of all types to rural locations throughout Alaska. The ADOT and Public Facilities (State of Alaska) is the current property owner, prior to statehood, the land remained in the public domain. The Air Force has never owned the land, and records of any improvements to the site do not exist. The former Long Range Radar Station (LRRS) is located approximately two to three miles southeast of the site. Aerial photos from August 25, 1969 indicates more than 500 drums were stacked in two similar sized piles approximately 150 ft. apart. 1977 aerial photos indicate that all but 10 drums from the southern drum pile had been moved, the northern drum pile still contained approximately 400 drums, fish camps were present in the tent city area west of the KDD. Aerial photos from 1987, vegetation obscures the view of the Drum Dump area, making an estimate of the number of drums difficult, but apparently many of the drums had been removed since 1977. The community of Kotzebue contends the drums were deposited by the Air Force during operations and closure of the LRRS. The Air Force contends that while the drums originally may have been Air Force property, the drums were utilized by local residents and deposited on the site after non-military use. A total of five surface soil samples were collected from the KDD to determine potential contaminants associated with the source. Two samples were collected from the southern stockpile (7,500 sq. ft.) and three samples were taken from the northern stockpile (75,625 sq. ft.). Surface samples were collected from 0 to 6 inches below ground surface (bgs). Gasoline range organics (GRO) was found in DD02SS at 420 mg/kg and diesel range organics (DRO) ranged from 13,000 mg/kg to 71,000 mg/kg and residual range organics ranged from 38,000 to 160,000 mg/kg. These petroleum contaminants were the only contaminants of concern that were detected above any applicable cleanup level. Based on the Preliminary Assessment, EPA does not anticipate further investigation under the Federal Superfund Program. Bruce Wanstall

11/19/2008 Update or Other Action Samples collected from pore water along the shore adjacent to the drum dump site. No contaminants were detected above cleanup levels. However, soil samples were not collected at this time and will be collected during the summer of 2009 to evaluate surface soil contamination. Visual evaluation indicates that surafec soil contamination as well as some drums remain on site. Tamara Cardona-Marek

8/27/2014 Offsite Soil or Groundwater Disposal Approved Based on results of remedial action report, DEC issued Non-objection letter (and soil transport approval form) for use of the former drum dump as materials site for airport runway/roads construction/expansion materials. Based on TCLP data submitted to DEC, DEC also approved segregating stockpiled soils into materials suitable as sub-grade materials and a new stockpile destined for disposal. DEC requested segrated soils be screend to omit DRO contaminated soils from sub-grade materials, and a separate soil transport approval form was issued. DEC also requested soils (meeting Artic Zone leanup levels, but above 40-inch zone migration-to-groundwater cleanup levels) and sub-grade materials be relocated inland and 50-feet from surface water.
