Exposure pathways identified as inhalation/ingestion of soil/dust and ingestion of surface water for Inupiat subsistence hunters and fishermen from the village of Wainwright; ingestion of sediment and surface water for waterfowl and shorebirds; inhalation/ingestion of soil/dust and ingestion of surface water and sediment from mammals; ingestion of soil for birds; and contact with surface water for aquatic organisms.

The sump was plumbed to discharge to the subsurface outside the foundation of the building. A sample collected in 1992 and documented in the Environmental Compliance and Investigation Report, dated 1992, showed elevated levels of total petroleum hydrocarbons, benzene, toluene, xylenes, and polycyclic aromatic hydrocarbons. In the Site Cleanup and Investigation Report, dated 1996, field activities are described concerning the sump including the removal of an unspecified volume of soil and the filling of the sump with concrete. Samples for volatile organic compounds and semi- volatile organic compounds were collected prior to filling with concrete and no elevated level of any analyte was detected. It is unknown if there are elevated concentrations of petroleum hydrocarbons or metals in the soil below the sump, however the sump has been filled with concrete and the area around it is a concrete pad covered with a building which will prevent the infiltration of water from the surface and the migration of contamination. Samples were collected at the FAA Fort outfall and no elevated levels were detected. As the contamination is not Yukon currently accessible to any potential receptors, the department determines Quarters that no further remedial action is planned for the Building 601 Sump. If, in the Facility future, the concrete floor is removed and the soil below and around the sump Bldg 601 is accessible, the area should be characterized and any contamination Soil Interior Airport managed in accordance with department regulations and guidance, as (concrete 25395 Sump Vicinity, Fort Yukon Open required by 18 AAC 75.325(i). 66.569722 -145.238611 pad) Building Hydrocarbons Robin des Bois - Alaska Contaminated Sites, Arctic Circle Page 1 of 141 15/12/2009 Family of Hazard ID Site Name Address City Status Spill Date Problem Latitude Longitude Medium Activity Contamination Site used as an open dump for 30 years.

During the phase I evaluation of the shop floors, the presence of stained soil was visually identified on the gravel floor of the SREB building at the Shungnak Airport. Nortech estimates approximately 3 cubic yards of contaminated soil remain at the facility. Phase I was limited to visual observations, no screening or analytical data. Visual observation suggest that Snow ADOT&PF potential contamination may be shallow in depth.
