Problems/Comments
A 1000 gallon gasoline tank was removed on August 4, 1989. Contaminated soil was excavated to 10 feet but no excavation confirmation samples were analyzed. Contamination appears to extend to the north, east, and west from the excavation based on field readings. 30.5 cubic yards of excavated contaminated soil was disposed of at the Anchorage regional landfill in 1991. Two soil borings and a monitoring well were installed as part of a release investigation in March 2005. That release investigation verified that the remaining soil and groundwater meet site cleanup levels. A No Further Action letter was issued on April 8, 2005.
