Reviewed Soil Stain Sampling Report prepared by URS for ADOT&PF, dated July 13, 2010 for field work completed on May 26, 2010. GRO up to 92.9 mg/kg; DRO up to 10,200 mg/kg; RRO up to 35,100 mg/kg; BTEX either not detected or well below the most stringent migration to groundwater cleanup levels. Former equipment building area is approximately 500 feet from the school and 900 feet from the Nushagak River (map in report says Kashugak River). Need to do more characterization to determine the vertical extent of contamination; the samples were hand-dug and only up to 14 inches deep. A well search is needed and water samples from the school and groundwater would help determine next steps. |

The Alaska Department of Environmental Conservation (ADEC) division of Environmental Health (EH) Solid Waste Program (SWP) performed a site visit on June 4, 2014.

Site Visit |
Two soil samples were collected from two stained areas at this site. Sample SS2 was collected from 24-inches below ground surface (BGS), and from a silt layer below stained gravel. Sample SS8 was collected from 18-inches bgs from a stained gravel material, and above the silt layer. Ground surface was visually stained in various areas. The tarp, which had previously covered the stained areas, was almost completely deteriorated. Analytical results showed elevated levels of DRO and RRO up to 4,290 mg/kg and 13,400 mg/kg, respectively, in Sample SS8. Results from Samples SS2 showed DRO and RRO at 42.8 mg/kg and 581 mg/kg, respectively; both of which are below ADEC cleanup levels. Estimated remaining contamination is 90 cubic yards in the surface soil; contamination is not expected in the sub-surface soils. |
