Problems/Comments

In 2000, petroleum contamination was encountered along the piping at the Yukon Delta Fisheries Development Association (YDFDA) tank farm in Emmonak. The tank farm consists of one horizontal diesel tank and three vertical gasoline tanks. Reportedly, the tanks are no longer in use due to the new consolidated tank farm completed in 2000. One soil sample collected 4.5 feet bgs from a soil boring just outside the southeast corner of the tank farm contained a benzene concentration of 0.0539 mg/kg. A 2006 DCRA image indicates the tanks are still present onsite.
