Meeting or Teleconference Held |
Contaminated Sites staff attended a meeting with the US Postal Service (USPS)in June to discuss contamination resulting from a leaking underground heating oil tank at the Fairbanks International Airport (FIA). FIA requested that the USPS remove the tank several years ago but the USPS did not respond so FIA removed it. Other areas of concern are a Class V injection well, another heating oil tank, and a pump island with associated piping. The USPS is willing to continue investigation and remedial activities at this site and FIA is seeking reimbursement for remedial actions taken to date. |

Site Characterization Report Approved |
The 2008 groundwater monitoring report was reviewed and monitoring recommendations were approved. Annual groundwater monitoring at the source area monitoring well FFLS-MW01 and down-gradient monitoring well FFLS-MW03 will continue. The analytical suite will include diesel range organics (DRO), gasoline range organics (GRO), benzene, toluene, ethylbenzene, and xylenes (BTEX), and polynuclear aromatic hydrocarbons (PAHs) during the 2009 monitoring event. Analyzing for PAHs was recommended because elevated concentrations of PAHs required sample dilution, which resulted in elevated practical quantification limits (PQLs) in 2008. No metals were detected above screening criteria during the 2008 monitoring event so additional testing is unnecessary. |

Site Characterization Workplan Approved |
Approved the final work plan to install ten soil borings around the perimeter and within the former UST excavation area to delineate the horizontal and vertical extent of remaining soil contamination. One of the borings will be completed as a monitoring well. Soil and groundwater samples will be analyzed for gasoline, diesel, and residual range organics; benzene, toluene, ethylbenzene, and xylenes; polunuclear aromatic hydrocarbons; volatile aromatic/aliphatic petroleum hydrocarbons; and extractable aromatic/aliphatic petroleum hydrocarbons. |

Site Characterization Report Approved |
Approved the final 2012 characterization report documenting soil and groundwater sampling results. Soil samples were collected from the perimeter and within the former UST excavation area. Results show that benzene, GRO, DRO, and PAHs are present above the DEC cleanup levels. One new groundwater monitoring well was installed and groundwater samples were collected from the 3 wells on site. Results from two of the wells show GRO, DRO, and benzene above the cleanup levels. |
