Problems/Comments

The site is at the former Rapid's Camp Helicopter Pad located approximately 3.5 miles southeast of the King Salmon Air Station (KSAS). SA06 is located in Ground Water Zone 6. This area was used for drum storage and disposal at the time that the KSAS was an active installation. Several intact and empty drums were found buried in the side of the bluff in June 2006. Several of the drums had military markings on them and were marked with "Unleaded Gasoline". A total of 77 drums were counted but it is suspected that additional drums are present in the bluff. Also a large amount of wood debris and other solid waste was found at the site. A total of 5 soil samples were collected beneath the larger piles of drums at the site and several analytes were detected below the cleanup levels. Additional sampling may need to be conducted to confirm that no exceedances are present in soils beneath the drums and in the area where the helicopters may have been refueled. Also, more comprehensive sampling may be required in the area of the drums as all of the samples collected were collected from surface soils.
