Problems/Comments

Historic fuel contamination discovered during construction of a new dormitory building. Site was a former equipment maintenance shop. The only samples taken were from the stockpile, low levels of gasoline range organics (GRO)(52 mg/kg), and diesel range organics (DRO) at 2000 mg/kg were reported. Area is in need of further characterization. On July 14, 15, and 18, 2005 contaminated soil from a utilidor excavation on the south side of the new dormitory building was segregated when field screning results were reported above 20 ppm. A total of 250 cubic yards of soil were sent to OIT for treatment. In 2015, soils and groundwater were sampled for GRO, DRO, residual rang organics (RRO), volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), polyaromatic hydrocarbons (PAHs), and metals. Arsenic, iron, chromium, and PCP exceeded project screening levels (PSLs) in soil. Arsenic, cobalt, chromium, manganese, and iron exceeded PSLs in groundwater. Soil gas samples had no analytes above PSLs. Compliance Site.

11/24/2008 CERCLA ROD Periodic Review ADEC issued a letter of concurrence on the 2008 Five-Year ROD review for Eielson AFB. In the letter ADEC concurred with the current remedies but recommends further work on the following: the vapor intrusion pathway needs to be evaluated for all potential receptors at WP45/SS57 site along with further evaluation of the selected remedy to ensure the Remedial Action Objectives are going to be met. The buried drums remaining at SS35 may still contain product that may pose a potential risk to ecological and human health risk in the future. The area of buried drums identified outside of SS37 may pose a threat of an imminent release of hazardous substances and warrants further investigation or response action. As stated in the 2008 Five-Year ROD Review, the overall long-term protectiveness determination for the Sitewide OU/Garrison Slough remedy will be further investigated. A Land Use Control Management Plan should be developed and implemented. Deborah Williams
