Staff received a final laboratory report from preliminary investigative sampling conducted by AIA for PFAS. The Aircraft Rescue and Fire Fighting Training Facility (ARFF) has been identified as a source of PFAS with 23,000 parts per trillion (ppt) perfluoroctanesulfonic acid (PFOS) indicated in shallow groundwater, 6,600 ppt in surface water, and 0.18 milligram per kilogram in soil. Sampling indicates the presence of other PFAS sources at ANC not yet identified. |

Update or Other Action |
ADOT&PF submitted a report to ADEC that details the sampling and analysis of soil for PFAS at the AFSC landspread area. PFOS was detected above migration to groundwater cleanup levels in two areas within the landfarm. ADEC met with ADOT&PF to discuss the management of the PFOS contaminated soils to protect human health and the environment. ADOT&PF is going to discuss management of the PFOS contaminated soils with AFSC since AFSC requested the soil be removed from the landspread area. |

Document, Report, or Work plan Review - other |
ADOT&PF provided a report to DEC that documents PFOS was detected at levels above migration to groundwater cleanup levels at the Taxiway Sierra proposed project site. ADEC would like to discuss removal/disposal of this soil in the near future with ADOT&PF. Update: on July 21st ADEC discussed disposal options with ADOT&PF. ADOT&PF is going to have internal discussions about potential disposal options and then reach out to ADEC. |
Todd Blessing |

Document, Report, or Work plan Review - other |
Staff approved of a ADOT&PF work plan to evaluate PFAS contamination at Taxiway Kilo. This site characterization is intended to inform AIA engineers and managers of PFAS contamination which may impact the construction phase of the improvement project. The end goal of this project is to properly characterize the soil that is to be excavated and removed to different locations within the airport, to ensure any PFAS-contaminated soil is separated and disposed of separately from clean soil. Soil free of contaminants will be moved to a location on airport property where the soil is needed to maintain level ground. If soil with high PFAS concentrations are discovered, the project engineers may choose to change the scope of the project to minimize disturbance of this soil. |
Todd Blessing |

Document, Report, or Work plan Review - other |
Staff reviewed Taxiway K PFAS sediment sampling report. The investigation was conducted to inform ANC engineers and managers, and DEC of PFAS contamination which may impact the design phase of the Taxiway K project. In order to minimize soil disturbance and removal until a long-term PFAS soil-management plan at the airport has been decided.
Sediment soil samples were collected from 7 drainage ditch locations and analyzed for PFAS.
The levels of PFOS and PFOA were below ADEC Method 2 Migration to Groundwater cleanup levels in 6 of the 7 locations. “Alpha West Drainage” was the only soil sample with results above migration to groundwater cleanup levels for PFOS only.
Staff sent an email to ADOT&PF approving of culvert inspections and limited soil removal from sampled culverts with the exception of Alpha West Drainage. Any soil removed from the culverts should be left on AIA property and it's disposal location documented.

Site Characterization Report Approved |
Staff reviewed and approved of a report that documented the sampling and analysis of a sediment sample from a drainage ditch and 6 soil composite samples from the surface north of the Lake Hood Airstrip area, where the ADOT&PF has determined soil removal may take place during a future Lake Hood Airstrip construction project. The results from six composite samples stretching across the surface of the Lake Hood Airstrip were non-detect for all 24 laboratory provided PFAS compounds, including PFOA and PFOS. The sediment sample results for the North Ditch revealed levels of PFOS above the DEC migration to groundwater level. PFOA was not detected in the north ditch sediment sample. |
