Leaking Underground Storage Tank Release Confirmed - Petroleum |
LUST Site created in CSP for source area ID 77824 Preliminary Release Investigation Report submitted by Bayliss, PE. Contamaination associated with a 10,000 gallon and a 550 gallon tank exists at this site. The airport terminal facilities are sited in an area which is hydrologically connected through surface and groundwater pathways. Spilled fuels and other substances tend to migrate extensively throughout the airport property. |

Underground Storage Tank Site Characterization or Assessment |
Received a report identifying GRO impacts to soil associated with 550-gallon gas tank. GRO contamination detected during excavation, 8 cy of contaminated soil was removed and contained with supersacks for transportation off-site. Brown and black oily oozes were observed in the groundwater that seeped from the pit walls. Total depth of excavation was 5 feet bgs. Analyticals show GRO up to 14,000 mg/kg, DRO up to 1,000 mg/kg, and benzene up to 1.9 mg/kg. Results indicate the presence of gasoline and Jet A fuel. |

Release Investigation |
Release Investigation and Exposure Pathway Assessment Report received by ADEC. Installation of SB-1 reveals that there is GRO and total xylenes contamination present in soil greater than ADEC soil cleanup levels. Possible source of contamination could be from Bering Air terminal. Four indoor air samples from the terminal were collected. Results from indoor air were inconclusive as to whether there is a potential exposure pathway from the subsurface vapors. |

Document, Report, or Work plan Review - other |
Two reports were reviewed. The "Alaska Airlines Kotzebue Terminal Building Expansion Soil Screening Report" and "2016 Groundwater Monitoring and Well Installation Report, Alaska Airlines Kotzebue Facility". An investigation of potential soil contamination within the area of the terminal expansion was conducted in 2016. Eleven shallow soil borings were installed, with field screening for hydrocarbons. Samples were collected for lab analysis from locations with highest screenings. In 9 of the 11 borings, gasoline range organics, diesel range organics, and benzene, toluene, ethylbenzene, and xylenes levels were detected, with exceedences of the Migration to Groundwater cleanup levels in four locations. No sample results exceeded the human health soil cleanup levels for the arctic zone. during terminal expansion, soils will be screened and disposed of or treated if levels of contaminants are detectable.
Three new monitoring wells were installed, one well was replaced and one well was decommissioned prior to sampling six wells for groundwater. DEC requests an additional well on the west side of the site to better define the contaminant plume remaining on site.

Lease agreements, lease lot histories, and deterrents to investigations were discussed. |

Samples from fourteen soil borings, and groundwater samples from seven monitoring wells resulted in finding contamination in "most of the same areas as previously reported". These source areas were: in the southeastern side of the building (former heating oil AST), south of the building (near the former and active fuel hydrants), northwest of the building (downgradient of former 550 gallon gasoline UST). |

A review of the 2021 Groundwater Monitoring Report was completed by DEC. After the 2018 report, it was agreed for the RP to conduct monitoring efforts every three years. The 2021 report documented diesel range organics (DRO) and benzene above the DEC Groundwater cleanup level in three of the five monitoring wells sampled (MW-1R3, MW-7, and MW-8). Ethylbenzene exceeded the Groundwater Cleanup Level in MW-7. Gasoline range organics (GRO) did not exceed Groundwater Cleanup Levels in the five wells sampled. No target analytes exceeded the Groundwater Cleanup Levels for monitoring wells MW-3R and MW-4R. Naphthalene exceeded cleanup levels in MW-7 and MW-8. DEC requested summaries of remaining contaminants in soil and groundwater surrounding the four identified source areas. |
