Problems/Comments
The Napaskiak Inc. Store Former Tank Farm site historically contained three 20,000-gallon aboveground storage tanks that were moved due to erosion threat. In 2001, soil samples collected from a 10 by 20 foot stain at this site, contained diesel range organics, gasoline range organics, BTEX, and naphthalene well above ADEC cleanup levels. This site is within about 75 feet of Z. John Williams school and 50 feet of a residence. Currently, as of September 2011, satellite imagery and a ADEC site visit indicates a new building may have been constructed over the stained contaminated area.

No discernable stain or distressed vegetation was noted. However, a new building which was constructed in 2005 may currently be located over the top of the stain. The building is built on support members on top of the ground with 2 feet of air space between the building and the ground. No soil was excavated during building construction. | Grant Lidren |
