Preliminary Assessment Approved |
ADOT contracted Shannon and Wilson, Inc. to investigate past uses and potential hazards at the site as part of a right-of-way road project. Shannon and Wilson, Inc. report, "Preliminary Hazardous Waste Site Evaluation, proposed Minnie Street Connector, Fairbanks, Alaska" indicates that no documented releases have occurred at this site, though a site visit revealed evidence of fuel spillage and releases from ASTs and fuel pumps. |

Site Characterization Report Approved |
(Old R:Base Action Code = SI - Site Investigation). DOT contracted Shannon and Wilson, Inc. to investigate site. Their report, "Final Report: Illinois Street and Minnie Street Connector Hazardous Waste Field Investigation, Phase II" dated 12/90 reports that 14 of 18 soil samples from monitoring wells exceeded 100 ppm TPH ranging from 21 - 120,000 ppm with the highest levels found at, or near the water table. All water samples had high levels of BTEX and a floating yellow product was observed in each of the 5 product monitoring wells ranging from 0.06' - 0.57'. 3 of 4 surface soil samples exceeded 100 ppm TPH and 1 sample contained 1.7 ppm PCE. |

Update or Other Action |
Nortech Environmental and Engineering Consultants submit Phase II sampling results and draft remediation workplan. Documented soil contamination associated former ASTs and injection well. Jonathan Williams, EPA UIC Region 10, sent report. Soil contamination consists of petroleum hydrocarbons. Site may in or nearby area-wide groundwater contamination as documented in USGS Water Resources Investigation Report Number 96-4049 dated 1996. |

Proposed Plan |
Plan to excavate contaminated vadose zone soil approved. Excavation to be directed by initial Phase II soil boring results and on-site trenching with soil gas screening and/or Hanby assays. Determination of the nature of onsite groundwater contamination and its relationship to area-wide groundwater contamination will be done concurrently with or after excavation. |

Update or Other Action |
Nortech requested an amendment to the approved cleanup workplan in a March 22, 2002 letter. Response sent stating that alternatives to the approved Method 2 standards requires a limited risk evaluation of additional pathways. Groundwater cleanup will probably be based on area-wide groundwater cleanup approach through FAIR. |

Update or Other Action |
HartCrowser submitted groundwater monitoring report for ARRC. AR12 and AR15 not sampled due to presence of product on the water table. DRO was the only petroleum compound exceeding cleanup levels (2.2 mg/L in AR-9). PCE exceeded cleanup levels in AR3 (0.016 mg/L). |

Update or Other Action |
HartCrowser submitted groundwater monitoring report for ARRC. AR-12 could not be found due to surface work at the site. AR3, AR9, and A15 were surveyed in May and elevations were compared to benchmarks on the adjacent Saupe's site. The highest level of petroleum contamination was found in AR-15 (DRO at 5.6 mg/L). Benzene and GRO were not detected above cleanup levels. All VOCs were all below cleanup levels, except PCE in AR3 (0.015 mg/L) |

Hart Crowser submits groundwater monitoring report for ARRC. Product present in AR-12 and AR-15. AR-12 contained 0.31 ft of product, the largest amount since monitoring began in 2003. File review indicates AR-12 is located near a former Van Gas dispensing area. A product sample was collected but results are not yet available. PCE exceeded cleanup levels in AR-3 (8.9 ug/L). |

Received September 2005 Groundwater Monitoring Report. According to the report, AR-3 and AR-9 were destroyed because of re-grading activities on the site. Floating free-phase product was observed in AR-12 so no sample was collected. One groundwater sample was collected from AR-15 and it had results of 46.7 mg/L DRO and 1.53 ug/L of benzene. |

Update or Other Action |
ADEC received the April 2006 Groundwater Monitoring Well Installation and Groundwater Monitoring Report from Hart Crowser. According to the report, three new monitoring wells were installed on the property. AR-9A was installed downgradient of the former excavation area; AR-3A was installed in the northern corner of the property; and AR-9B was installed in the south east corner of the property (upgradient). Soil and groundwater results were non-detect for AR-3A and AR-9A, but AR-9B had DRO levels up to 13,300 ppm and GRO levels up to 512 ppm in the soil and DRO levels up to 18.2 ppm and benzene levels up to 15.5 ppb in the groundwater. AR-12 and AR-15 were not sampled because they both contained free-phased floating hydrocarbons. |

ADEC received the March 2007 Groundwater Monitoring Report for the Van Gas site. HartCrowser determined that the groundwater flow direction was in the west-northwest direction. Free-phase hydrocarbons were measured in AR-12 and AR-15 at a thickness of 0.01 foot. GRO, DRO, RRO and BTEX was non-detect in AR-3A and AR-9A. AR-9B had GRO levels up to 2.09 mg/L, DRO levels up to 8.63 mg/L and benzene at 0.026 mg/L. |

The wells sampled included AR-3A, AR-9A, AR-9B, AR-12, AR-15, AR-104, and MW-4. AR-104 and MW-4 are located west of the site on Minnie Street and at 1301 Well Street (Hazard ID 25403)and were sampled in the past as part of other sites or for areawide evaluation in the railroad industrial area. Results exceeding DEC groundwater cleanup levels included: PCE in MW-4 and AR-3A; TCE in AR-3A; benzene and DRO in AR-9B and AR-12; DRO and RRO in AR-9A; and DRO in AR-15. No contaminants exceeded cleanup levels in AR-104. |

Groundwater monitoring report submitted by Fairbanks Environmental Services. Samples were collected on October 10, 2013 from AR-3A, AR-9A, AR-9B, AR-12, and AR-15. Groundwater flow direction was to the west-northwest which is typical in this area. No floating product was observed. Results showed that DEC groundwater cleanup levels were exceeded for DRO in AR-9B, AR-12, and AR-15. Benzene exceeded cleanup levels in AR-9B and AR-15. |

Groundwater monitoring report submitted. Five wells were sampled on September 20th, including AR-3A, AR-9A, AR-9B, AR-12, and AR-15. Sheen was observed on AR-9B and AR-15. Benzene exceeded DEC cleanup levels in AR-9B and AR-12. DRO exceeded cleanup levels in AR-9B, AR-12, and AR-15. PCE and TCE exceeded cleanup levels in AR-3A. Concentrations were similar to those observed in previous monitoring events, except for DRO and RRO in AR-9B, which were elevated. Depth to groundwater was observed to be about 12 feet and groundwater flow direction was west-northwest. Groundwater table was higher this year than is typical. |
