Problems/Comments
The Control Tower Building was located on the west side of the Skwentna FAA Station, at the one turn in the road going to the SBRA Range Building. The Control Tower Building consisted of several towers and a 16 by 24-foot building with an aboveground storage tank at the end. Diesel range organic and polycyclic aromatic hydrocarbon contamination was detected in soil samples at concentrations above the ADEC cleanup levels.

DRO was detected in one soil boring at concentrations up to 13,100 mg/kg. PAH concentrations were also detected in the same boring at concentrations above the ADEC soil cleanup levels. One groundwater monitoring well was installed at the site, and contamination concentrations were not detected above the ADEC groundwater cleanup levels. Recommendations for the site include removing the small volume of petroleum-contaminated soil. | Jessica Morris |
