Site Characterization Workplan Approved |
Approved Phase 2 Release Investigation Work Plan to delineate the horizontal and vertical extent of petroleum contamitaion using Ultraviolet Optical Screening Tool (UVOST) with Laser-Induced Fluorescense (LIF) to provide real time field screening data, collecting soil samples for laboratory analysis, and installaing and sampling 5 monitoring wells to determine the presence of petroleum in the groundwater. |

Document, Report, or Work plan Review - other |
Approved the Sampling and Analysis Plan describing the removal of lead-acid batteries near the Non Directional Beacon (NDB) area. An area approximately 20’ by 10’ contains broken lead-acid batteries, which will be removed and transported off site for disposal along with lead contaminated soil. Surface soil metals concentrations will be measured in the field using an x-ray fluorescence detector and confirmation samples will be collected for laboratory analysis. |

Document, Report, or Work plan Review - other |
Received the final report documenting removal of lead-acid batteries and associated lead impacted soil at the Non Directional Beacon area. Broken lead-acid batteries and associated soil were removed from a 16’ by 17’ area and transported offsite for disposal. Field screening was performed using an x-ray fluorescence detector, and confirmation samples were collected for laboratory analysis. Confirmation sample results show lead contaminated soil remains onsite. The FAA will return to the site to perform additional removal actions. |

Document, Report, or Work plan Review - other |
Approved final work plan for soil removal at lead battery area of concern and groundwater sampling at petroleum contamination area of concern. Field screening for lead will be performed with an x-ray fluorescence detector and confirmation samples will be collected and analyzed for lead once removal actions are complete. Groundwater at the petroleum contamination area of concern will be sampled for gasoline, diesel, and residual range organics and benzene, toluene, ethylbenzene, and xylenes. |

Document, Report, or Work plan Review - other |
Approved final 2014 Groundwater Monitoring and Soil Remediation Report. Groundwater sampling results shows DRO, GRO, and benzene remain above cleanup levels. Approximately 1.5 cubic feet of lead contaminated soil was removed from the battery disposal area and transported offsite for disposal. Confirmation sampling shows remaining concentrations of lead are below the cleanup level. |
