Update or Other Action |
Fairbanks Fuel Facility dated July 29, 1988, submitted by Woodware-Clyde Consultants, and received by ADEC on this date. A soil gas survey was conducted to determine if soil/ groundwater was contaminated. 17 soil gas probes and 5 probes into the groundwater were installed. Depth of water was found to be 20 feet bgs. Sample 15 indicated 4 feet of product thickness. Significant contaminated soil and water found throughout the site. Groundwater appears to be affected by the Chena River, thus producing a large horizontal and vertical smear zone, which is approximately 400 feet long and 24 feet wide. It is recommended that product recovery measures are taken for future remediation. |

Recieved Fairbanks Rail Yard Soil and Groundwater Assessment Report. December, 2005. Report states two new GW monitoring wells installed, three soil borings advanced. New wells are MW-5 and MW-6. Soil samples were collected from the borings for these wells and from boring B-1. DRO was detected at 4,490 mg/kg at 15-17 feet bgs at the GW interface in boring MW-6, and at 4,510 mg/kg at the same interval in boring B-1. Free-phase product was observed in wells WC-3, MW-1, and MW-2 and in the purge water from MW-6. Groundwater samples were collected from MW-3, MW-4, and MW-5 and analyzed for DRO, GRO, RRO, and BTEX. DRO was above Table C in each of the three wells sampled ranging from 2.71 mg/l in MW-3 to 6.07 mg/l in MW-4. Report recommends GW sampling in Spring 2006. |

On this date, ADEC received the Groundwater Sampling Report Fairbanks Rail Yard, submitted by Clarus, dated January 2010. Groundwater was measured approximately 15 ft. bgs and found to flow west. Free-phase product was measured to 0.04 foot in MW-2 and 0.02 foot in WC-3, therefore these MWs were not sampled. Four of the five MWs sampled; MW-1, MW-4, MW-5, and to MW-6; which were analyzed for BTEX, GRO, DRO, and RRO; contained DRO concentrations above ADEC cleanup levels with the highest concentration in MW-1 with 154 mg/L DRO. Two of the five MWs sampled, MW-1 and MW-6, contained RRO concentrations above ADEC cleanup levels, with 11.8 mg/L and 1.51 mg/L respectfully, as well as a hydrocarbon sheen. MW-6 also contained benzene up to 0.00635 mg/L. MW-3 was the only MW sampled, which did contain concentrations above ADEC cleanup levels. |

On this date, ADEC received the Groundwater Sampling Report Fairbanks Rail Yard, submitted by Clarus, dated October 2010 (Note: ADEC did not receive a work plan for this field effort). MW-3 and MW-6 were repaired prior to sampling. Groundwater was measured approximately 15 ft. bgs and found to flow southwest. Free-phase product was measured to 0.04 foot in MW-1 and 0.06 foot in WC-3, therefore these MWs were not sampled. The location of MW-5 could not be confirmed. Three of the four MWs sampled; MW-2, MW-4, and MW-6; which were analyzed for BTEX, GRO, DRO, and RRO; contained contaminants above ADEC cleanup levels. MW-2 was most contaminated with DRO up to 187 mg/L, RRO up to 6.81 mg/L and benzene up to 0.0088 mg/L. |

On this date, ADEC received the Site Characterization Report December 2011 submitted by RSE dated December 2011. The historic MW located down gradient of MW-6 formerly known as WC-2 was replaced and relabeled MW 7. Groundwater samples collected from four MWs contained: benzene at 0.00527 mg/L and DRO at 99.5 mg/L in MW-1; DRO at 3.37 mg/L in MW-4; DRO at 118 mg/L in MW-6; and DRO at 19.6 mg/L in MW-7. The other four onsite MWs were not sampled, because MW-2 and WC-3 contained free product and MW-3 and MW-5 could not be located. The groundwater gradient is fairly flat, but trends in a south direction toward Chena River. |

Document, Report, or Work plan Review - other |
ADEC has reviewed a groundwater monitoring report received on this day. The report indicates that 9 monitoring wells (MWs) inspected for free product and groundwater elevations were measured. MW-1, MW-3, and WC-3 contained free product so 6 wells were sampled (plus one duplicate) to include MW-4 through MW-9. Samples analyzed for GRO, DRO, RRO, BTEX, and PAHs. MW-8 and MW-9 had no observed exceedances of ADEC Approved Groundwater Cleanup Levels (GCLs). All other wells contained one or more of the following COCs which exceed GCLs: DRO, RRO, Benzene, 1-Methylnaphthalene, 2-Methylnaphthalene, and Naphthalene. A Mann-Kendall Trend analysis using new and historic analytical results was conducted to determine if data indicates an increasing, stable, or decreasing concentration of COCs. Increasing trends in GRO, DRO, RRO, benzene, and ethylbenzene at multiple monitoring wells downgradient from the former storage tanks suggests that contamination may be migrating in a downgradient direction. |
