Site Ranked Using the AHRM |
Preliminary ranking. The drinking water source for the village is derived from snow melt and a lake reservoir which is over 2 miles away from this site. Assignment of Surface Water Exposure Index as "0" in order for the site to rank. |

Site Visit |
ADEC performed a site visit on this date. Pictures taken. The historic red vertical tank has been relocated north to the current fueling station offsite. The onsite building has collapsed into a pile of rubble. Sheen noted, but may be biogenic. Old fueling pump, header, piping and horizontal drums noted. This site is adjacent to an eroding river bank and the old BIA TF. |

Document, Report, or Work plan Review - other |
Reviewed the Site Characterization Work Plan, dated July 2015. The proposed activities consist of advancing numerous soil borings (using hand tools) to groundwater and collecting analytical soil and water samples based on visual, olfactory, and field screening results. Additionally, a soil sample is planned from the river bank, provided the area can be assessed safely. Surface water samples will be collected if surface water is present. |

Document, Report, or Work plan Review - other |
Reviewed the Subsurface Investigation Report, dated September 11, 2015. The objective of this investigation was to delineate the vertical and horizontal extent of contamination identified in 2001. Six soil borings were advanced in the area of former contamination, and to depths varying between 1 and 4.5 feet below ground surface. Groundwater was not encountered in any soil borings. At least two soil samples were collected from each boring and were field screening using a photoionization detector (PID). Based on PID headspace field screening, visual evidence of contamination, and odors, a total of 14 soil samples were submitted for laboratory analysis of diesel range organics (DRO). An additional soil sample was collected from the nearby river bank, roughly 25 feet to the east. All results exceeded ADEC migration-to-groundwater cleanup levels, but were below health based ingestion and inhalation cleanup levels. The maximum concentrations reported in the surface soil was 7,670 mg/kg DRO. The maximum concentration reported in the subsurface soil was 3,970 mg/kg DRO. The sample collected from the river bank exhibited a concentration of DRO at 841 mg/kg. ADEC responded to report via letter dated September 23, 2015. Further delineation requested. |

Document, Report, or Work plan Review - other |
Reviewed the Follow-On Site Characterization Work Plan, dated February 22, 2016. Activities described in the work plan mainly consist of advancing three test pits to groundwater adjacent to the Kwigillingok River and collecting water samples for analysis of total aromatic hydrocarbons (TAH) and total aqueous hydrocarbons (TAqH) to show that surface water is not impacted.
The work plan presented several soil boring logs for wells that were drilled in the past. Each boring log indicated that frozen soil was encountered at roughly six feet below the ground surface, suggesting that the site is underlain with continuous permafrost. ADEC concurs that permafrost is prevalent in the vicinity of this site and that the main concern is potential impacts to surface water. |

Document, Report, or Work plan Review - other |
Reviewed the Follow-On Site Characterization Report, dated July 26, 2016 for the Kwigillingok Kwik Incorporated Former Tank Farm site. Water samples were collected from three hand-dug test pits along the riverbank (up-gradient, side-gradient, and down-gradient). The test pits were dug in the sediment of the riverbank and were submitted for analysis of total aromatic hydrocarbons (TAH) and total aqueous hydrocarbons (TAqH). The side-gradient sample, which was located directly east, and nearest to the former tank farm exhibited a concentration of TAH at 14.5 micrograms per liter (ug/l) and TAqH at 14.9484 ug/l. The Alaska Water Quality Standards (AWQS) for TAH and TAqH are 10 ug/l and 15 ug/l, respectively. In a letter dated August 11, 2016 ADEC requested a work plan by November 1, 2016. Work plan should include provisions to 1) remove all remaining debris from the site that is associated with the tank farm; 2) remediate or remove, or otherwise mitigate the risk of contamination impacting surface water; 3) perform shovel-sheen testing; 4) perform sediment sampling; and 5) continue monitoring for TAH and TAqH.
