Update or Other Action |
Shannon & Wilson conducted a site reconnaissance on 26 Sep 2001 as part of a Denali Commission assessment. The AST is a double-walled, horizontal, skid-mounted, welded steel, dike tank that appeared to be in good condition. The facility operator (Mr. Ernie Thomas) was unaware of any releases or problems associated with the AST.
No surface stains were evident, and no active leaks were observed. However, PID field screening measurements ranged from <1 to 150 ppm around the tank. Soil on the west side of the AST contained up to 1,380 mg/KG DRO, 46.5 mg/Kg GRO, <0.0175 mg/Kg benzene, <0.0699 mg/Kg toluene, 0.124 mg/Kg ethylbenzene, and 0.277 mg.Kg total xylenes at 1' BGS.
Soil north of the AST contained 1,960 mg/Kg DRO, 107 mg/Kg GRO, <0.0186 mg/Kg benzene, <0.0745 mg/Kg toluene, 0.408 mg/Kg ethylbenzene, and 0.661 mg/Kg total xylenes.
Contamination is likely a result of overfilling or spills during filling or vehicle fueling. |

Update or Other Action |
Met with Jon Menough of VSW program regarding upcoming work in Buckland. He confirmed that the water intake for the village is currently upstream from the village and that "Plan A" has it again going in upstream although an alternative plan would place it in a downstream location and he is now informed of the potential concerns regarding such a placement. The construction project will have DEC and construction oversight staff in the village very often over ~ next 3 years. |

Update or Other Action |
Reconfirmed with Debra Addie on 1/14/2010 about location of water intake location as the drinking water program maps/tools have it an incorrect location downgradient. |

Meeting or Teleconference Held |
Spoke with ADOT&PF (Sam Myers) to promote additional characterization and potentially even remediation at this site in 2013. Mr. Myers is receptive, so we'll work together over the coming months to formalize a plan. |

Update or Other Action |
Spoke with Clarence Thomas (Public Water Administrator) at the Buckland City Office (494-2121) and learned that Buckland get its water from the Buckland River, and their public water intake is located at 655829.3N 1610732.1W (Coords obtained from Google Earth during discussion with Mr. Thomas). This intake is upstream from all known or suspected contaminated sites in Buckland. |

Meeting or Teleconference Held |
Spoke with Mr. Sam Myers (ADOT&PF) again to discuss the type of information that ADEC will need in order to progress toward site closure. Three surface soil samples surrounding the AST, and subsurface soil samples (as needed based on field screening) should allow characterization, but a groundwater sample may become necessary, if there are indications of subsurface soil contamination at depth and if the pad is saturated. Additional characterization may or may not become necessary based on results of initial sampling event. |

ADEC has approved the transport and disposal of 60 cubic yards of contaminated soil to the Buckland landfill pending acceptance by the ADEC solid waste program and the landfill operator. |

Site Characterization Report Approved |
Received characterization report from ADOT on 10/3/2018, that includes work conducted in summer 2019. ADEC has reviewed the report and it is now approved. 60 cubic yards of petroleum contaminated soil was excavated from the north side of the SREB and disposed of in the Buckland landfill. Field screening measurements and analytical samples were collected from the sidewalls and base of the excavation. Samples were below ADEC cleanup levels for all contaminants of concern (COC). A stain was observed on the west side of the SREB beneath the skid mounted AST fill line and appeared to extend ~2 feet deep and underneath the tank. The portion of the stain that was not under the tank was removed with hand tools. A single PID reading was taken from the stain area and measured 15,000 ppm. Nine post holes were dug around the north side of the SREB as part of a security fence installation. All post holes were field screened with a PID. An analytical soil samples was collected at the post hole with the highest field screening. PH7 had a DRO concentration of 423 mg/kg, which exceeds migration to groundwater cleanup levels. |

Update or Other Action |
Met with ADOT&PF to discuss construction work plans at the airport. Although their plans do not currently involve any soil or groundwater disturbance or stockpiling within the boundaries of the contaminated site, ADEC suggests they complete a Soil-Groundwater Management Plan prior to starting construction. Construction is scheduled to begin in Summer 2023. |
