Update or Other Action |
Met with DOT to discuss monitoring program. DOT will conduct release investigation identify remaining soil and groundwater contamination. Monitoring wells have been in place since 1993, but are not place in association with plume delineations. Benzene, DRO, and lead have been present above cleanup levels in monitoring wells. Solvents (1,1,1-TCA, cis-1,2-DEC, dichlorofluoromethane, trichlorofluoromethane, and vinyl chloride) have been detected in groundwater. |

Underground Storage Tank Site Characterization or Assessment |
Received a groundwater monitoring report for the site dated December 7, 2005. Groundwater near the former tanks on the west side of the building contained DRO up to 3.7 mg/kg, GRO up to 21.3 mg/kg and exceeded cleanup levels for benzene, toluene, and ethylbenzene. DRO at the Former sump location was 14.3 mg/kg. MW-8 down gradient of the former tanks contained GRO to 8.50 mg/kg and benzene to 2.0 mg/kg. MW-9 was non detect for DRO and below the cleanup level for benzene. ADOT plans to do additional investigation of UST 1-4, requests a NFRAP or NFA status for tanks 8 and 16. |

Document, Report, or Work plan Review - other |
Kris Dubois dropped off a copy of a 2003 Septic Crib Characterization Report. The septic system was abandoned when the building was connected to GHU in 2003. Prior to this time, floor drains with sediment traps and oil water separators had been connected to the septic crib. Shannon & Wilson collected a sample from the bottom of the crib which consisted of gravel fill. The sample did not elevate PID readings, and was not suitable for laboratory analysis. The onsite well did not contain VOCs or fecal coliform contamination above PQL's. 3 soil borings were completed as monitoring wells. Soil and groundwater from these borings did not contain analytes above laboratory PQL's and Shannon & Wilson concluded that the groundwater had not been adversely affected by the septic crib. The scope of work did not include Class |

Site Characterization Workplan Approved |
Approved work plan for 2008. FIA plans to drill and sample two soil borings in DRO hot spots from soil gas survey; install and sample a groundwater monitoring well in BTEX hotspot from survey; six monitoring wells will be installed and sampled along western property boundary. EDB/EDC detected above cleanup levels in MW8. Awaiting final report from summer 2008. |

Document, Report, or Work plan Review - other |
Recieved January 2009 Groundwater Investigation Report. The report included sampling results of existing monitoring wells, installing and sampling a well in the BTEX hot spot soil gas survey, sampling two soil borings at DRO hot spots, and installing and sampling monitoring wells near the downgradient property line. Significant findings include: the benzene plume from the UST source area likely crosses the western property line and gw contamination is present at MW-16 from an unknown source upgradient. Recommendations include obtaining gw elevation measurements, consider remedial options |

Update or Other Action |
On 9/8/09, S&W submitted a workplan for further investigation for elevated concentrations of benzene in MW-12 and MW-16. However, Rebekah Cadigan with DOT called and indicated budgeting constraints will prevent them from following through with the investigation this fall. This work will be conducted in the spring instead. DOT will proceed with groundwater monitoring and a possible well search will be completed this fall. |

Document, Report, or Work plan Review - other |
DEC received from FIA the 2010 SLR Report for additional groundwater monitoring and site evaluation.
Volatile concentrations in groundwater were lower than the previous sampling event. MNA parameters were measured,an updated conceptual site model was submitted as well as building survey for vapor intrusion. |

Meeting or Teleconference Held |
Meeting with DEC, ADOT&PF, and SLR to discuss current status and pending work on the site. Several wells in which contaminants have never been detected above cleanup levels will be decommissioned, while other wells will remain for ongoing monitoring. Source area wells and downgradient monitoring wells will be sampled this year for GRO, BTEX, MNA parameters, and sulfate-reducing microbes to evaluate the effectiveness of sulfate injection on biostimulation and to get a current baseline prior to additional sulfate injections. MW-5, MW-12, and MW-10 will be added to microbial characterization sampling (qPCR) in order to get a more comprehensive view as well as an upgradient sample (MW-5) for comparison. Additional sulfate injections will take place this field season, but concentrations will be reduced and the duration of injection extended relative to last year's treatment. |
