​Soil: Diesel-range organics (DRO) were detected at concentrations greater than Alaska Department of Environmental Conservation (ADEC) Method 2 cleanup level for the migration to groundwater pathway (Table B2 of Title 18, Chapter 75, Section 75.341[d], of the Alaska Administrative Code [AAC]) for sites with annual precipitation greater than 40 inches in surface and subsurface soil to approximately 8.5 feet below ground surface (bgs). 1 Methylnaphthalene and 2-methylnaphthalene were detected at concentrations greater than the ADEC Method 2 cleanup levels for the migration to groundwater pathway (Table B1 of 18 AAC 75.341[d]) for sites with annual precipitation greater than 40 inches in surface and subsurface soil to a depth of approximately 2 feet bgs.
