Mr. Himanshu H . Mehta, P .E . <br /> 20 December 2013 <br /> Page 3 <br /> activities will include scheduling and staffing, subcontracting, coordination with the analytical <br /> laboratory, and field equipment preparation . <br /> Replacement monitoring wells will be installed using a sonic drill rig and constructed similar to <br /> existing Site monitoring wells . Monitoring wells will be constructed of 24nch Schedule 40 <br /> (SCH 40) polyvinyl chloride (PVC) with 10 ft of 2 -inch SCH 40 PVC standard factory-slotted <br /> (0 . 0104nch) screen . The wells will be completed flush with ground surface in a traffic-rated <br /> manhole vault placed in a 2 ft by 2 ft concrete pad . The wells will be developed until visually <br /> free of particulates, as observed by the on-Site Geosyntec representative . It has been assumed <br /> that the well installation, development, and surveying activities can be completed in two field <br /> days with one person . <br /> Any soil or liquid investigation-derived waste (IDW), consisting of soil cuttings from well <br /> installation, decontamination fluids and well development water, will be placed in 55 -gallon <br /> drums, labeled , and staged at the Gifford Road Landfill . One representative sample for TCLP <br /> from each waste stream (solid and liquid) will be collected for waste characterization . <br /> Geosyntec will arrange for transportation of the drums for disposal at the IRC Main Landfill in <br /> Vero Beach, Florida. Solid and liquid waste will be analyzed for TCLP short list of CVOCs and <br /> benzene, toluene, ethylbenzene, and xylenes (BTEX) . In addition, liquid waste will be analyzed <br /> for pH and flashpoint. Waste characterization samples will be collected concurrently with the <br /> field activities described above . Budget has been included herein for transportation to the <br /> landfill ; however, it has been assumed that IRC SWDD will be responsible for disposal costs <br /> associated with the non-hazardous drum disposal . <br /> FDEP approved discontinuing the use of the IP&T system in conjunction with implementation of <br /> Remedial Action Plan Modification (RAPM) activities in 2008 . Since that time, the air stripper <br /> has been kept on- site for treatment of purge water. It is our understanding that because of <br /> potential future site redevelopment activities currently under discussion, the system will be <br /> dismantled and decommissioned. Geosyntec will characterize the GAC for disposal, as well as <br /> provide oversight and coordination of a remediation contractor to transport the spent GAC to the <br /> IRC Main Landfill for disposal . Under this task, one sample will be collected from the GAC <br /> vessel and analyzed for TCLP CVOCs and BTEX . One field day for one person has been <br /> included for oversight of GAC transport and disposal activities . It has been assumed that the <br /> remediation contractor will vacuum the GAC from the vessels and transport the spent GAC to <br /> the IRC Main Landfill, where it will be disposed of as non-hazardous waste . Budget has been <br /> included for transportation to the landfill ; however, it has been assumed that IRC SWDD will be <br /> responsible for disposal costs associated with the non-hazardous GAC disposal . <br /> Geosyntec will perform PDB deployment activities associated with the CVOC plume monitoring <br /> wells a minimum of two weeks prior to the summer semi-annual sampling event . PDBs are <br /> anticipated to be purchased from EON Products, Inc . and it has been assumed that they will be <br /> deployed in one field day by one person in conjunction with other Site work. <br /> XR 13056\PR 13082- 122013 .docx <br /> engineers I scientists I innovators <br />
