Meeting or Teleconference Held |
Met with DOT to discuss monitoring. Petroleum monitoring will be reduced to MW-25, MW-15, MW-18, MW-33, MW-28, and MW-32. MW-11, MW-12, and MW-34 will continue to be monitored for chlorinated solvents. |
Janice Wiegers |
| 7/27/2004 |
Meeting or Teleconference Held |
Met with DOT and Oasis to discuss NFRAP request and provide comments from the ADEC risk assessor for alternative cleanup levels proposed in the 1999 Expedited Site Assessment/Release Investigation. FIA will address comments before further consideration is given to a NFRAP. Solvent issues will be addressed in a separate site as the hydrant fuel line is not the source of this contamination. Also clarified that petroleum contamination in from the hydrant fuel line is regulated under the LUST regulations, as previously agreed on. |
Janice Wiegers |
| 12/21/2004 |
Update or Other Action |
Groundwater monitoring report submitted for drainage pond investigation. Tetratchloroethene, trichloroethene, cis-1,2-dichloroethene, and vinyl chloride remain above cleanup levels in MW-11. A trend analysis of the 1999 to 2004 data indicates that the solvent concentrations in MW-11 may be slightly increasing - although the plume is believed to be stable. Oasis recommends installation of an additional monitoring well and replacement of MW-11. |
Janice Wiegers |
| 8/17/2005 |
Update or Other Action |
Site name changed from FIA- Hydrant Fuel System to FIA - Drainage Pond. This site will be used to track solvents that were identified during investigation of the hydrant fuel releases. The petroleum issues associated with the hydrant fuel line will now be tracked in the LUST database under Event 2908. |
Janice Wiegers |
| 12/16/2005 |
Update or Other Action |
Groundwater monitoring and well removal report submitted. Wells MW-1, 3, 6, 7, 8, 13, 14, 16, 17, 19, 20, 24, and 26 were decommissioned. Before decommissioning, groundwater samples were analyzed for BTEX, GRO, and DRO from MW-1R, MW-19, MW-20, MW-24, and the lawn watering well. MW-1R contained DRO above cleanup levels, so it was not removed. No contaminants were found in the lawn watering well. The firefighting well at the Airport Rescue and Firefighting building was not sampled because it is not used and DOT plans to decommission it. All remaining wells were resurveyed for elevation.

Janice Wiegers |
| 12/19/2005 |
Update or Other Action |
Further VOC Characterization at Former Drainage Pond, report received. Tetratchloroethene, trichloroethene, cis-1,2-dichloroethene, and vinyl chloride remain above cleanup levels in MW-11R, which replaced MW-11 due to poor recharge. This well was sampled at the 15, 25, and 34.5 feet. The highest concentrations of tetratchloroethene, cis-1,2-dichloroethene, and vinyl chloride were reported at the 34.5 foot depth. The report recommends reinstall of MW-29 which is no longer usable, new MW's further downgradient of MW-34 and 35, evaluation of natural attenuation of chlorinated solvents, and use of passive diffusion membrane sampling in MW-11R. |

| 10/20/2006 |
Site Characterization Workplan Approved |
Site Characterization Work Plan submitted by FIA, prepared by Oasis. 54 soil gas modules will be placed in a grid pattern covering the site, and the area north of Airport Industrial Road. PCE and TCE were observed to increase in concentration at a depth of 35 feet in MW-11R during a 2005 sampling event. Passive diffusion bag samplers will be used in MW-11R to determine if the 2005 data is real or an artifact of the low flow sampling method employed at that time. Groundwater samples will be collected from the existing wells, two new wells downgradient of MW11-R, and replacement wells for MW-29 and MW-30. |

Site Number Identifier Changed |
Contamination was first discovered at this site in 1993 during construction of a new storm sewer. Further site characterization efforts lead to the discovery of free product associated with the Hydrant Fuel Line. This contamination was tracked in the LUST database under event ID 3016. The Hydrant Fuel Line site achieved a ‘no further remediation planed status’ in February 2006. To differentiate the solvent contamination at the Former Drainage Pond from the Hydrant Fuel line the file number has been changed to 100.38.188. Refer to file # 100.38.128 and LUST event ID 3016 for historic site information. |

Site Characterization Report Approved |
Approved work plan for source characterization near monitoring well MW-11R and annual monitoring at six monitoring wells. Goal is to delineate the extent of PCE contaminated soil. Natural attenuation monitoring will also be included in report. |
Neal Everson |
| 11/27/2007 |
Update or Other Action |
Reviewed report of Further VOC Characterization dated 26 Mar 2007. The soil gas survey and gw monitoring results helped delineate the area of chlorinated compound contamination which appears to be relatively small and mostly confined to area around MW-11R. Results of work from fall 2007 work plan will arrive shortly. |

Site Characterization Report Approved |
DEC reviewed the 2008 Groundwater Monitoring Report and Feasibility study by Oasis Env. 3 MWs were sampled, including nested well MW-11R with Passive Diffusion Bags. MW-11R remains the only well with concentrations of VOCs exceeding cleanup levels. MW-11R contained PCE, TCE, cis-1,2-DCE and vinyl chloride above cleanup levels. Oasis recommends additional characterization of source area by 1. installing dataloggers, 2. determine vertical distribution of soil contamination, 3. install new groundwater monitoring wells to better delineate gw plume, 4. collect discrete gw samples from depth to verify MW-11R sampling results. Feasibility study evaluates remediation alternatives. Recommended approach is substrate addition (HRC) to stimulate reductive dechlorination by MNA after further site characterization. |

Long Term Monitoring Workplan or Report Review |
DEC reviewed the revised 2023 Drainage Pond Groundwater Monitoring Report which documents groundwater sampling conducted in August 2023 at monitoring wells MW-11R, MW-34, MW-38S [shallow], MW-38D [deep], MW-39, and MW-40. Samples were analyzed for benzene, tetrachloroethylene (PCE), trichloroethylene (TCE), cis-1,2-dichloroethylene (DCE), trans-DCE, vinyl chloride and natural attenuation parameters. The highest contaminant concentrations were observed at MW-11R, MW-40, and MW-38S. Depth to groundwater was 4.09 to 6.00 feet below ground surface and groundwater flow direction was to the southeast. Additional site characterization will be completed during the next biennial groundwater monitoring event, including installing temporary well points and advancing soil borings to define the extent of contamination, determine if contamination is confined to the lot boundary, and evaluate if there is a potential source present in the subsurface (buried asphalt was identified in the vicinity of MW-38 during the 2010 site characterization event). |
