Martin Thorpe k j * <br /> 19 May 1987 <br /> w <br /> Four-inch diameter ground water monitoring wells will be installed. in the <br /> three boreholes. Appropriate disposal of drill cuttings will be determined <br /> from the soil analysis of the borehole simples. <br /> TASK 2 - WELL DEVELOPMENT, SAMPLING AND CHEMICAL ANALYSIS t xl <br /> _ T <br /> The monitoring wells will be developed by airlift evacuation with "� t <br /> development water directed to a plastic-lined debris box stored on-site, <br /> i <br /> After development, one water sample will be collmcted from each well and the 4 <br /> 2 'debris box. The samples will be refrigrated and delivered to an analytical <br /> laboratory under chain-of-custody procedures. The ground water samples will <br /> { <br /> be analyzed by GC/FID/photo ionization detection (YID) for TFHC and BTX, by f <br /> GC/electron capture detection (ECD) for EDB, and by AA for SL. Development <br /> water will be analyzed by GC/FID/PID'for TFC knd BTX and will be disposed Jig rv; <br /> appropriately depending on TFHC and BTX conceatiations. ," <br /> Costs for potential disposal of the development water or drill cuttings rf ¢' <br /> as a hazardous waste are not included in this ,proposal. <br /> TASK 3 - REPORT PREPARATION <br /> After we have reviewed all field and laboratory data, we will prepare a <br /> letter report documenting our field activities and findings. The report will <br /> include: <br /> o Site background and a description of tasks performed; <br /> o Lithologic logs of soil borings and monitoring well oonstruction <br /> details; <br /> o A table summarizing OVA and laboratory analytic results; and. <br /> o Data analysis, interpretations and conclusions. <br /> A draft report will be furnished for your review and comment. After your <br /> comments have been addressed, our final report will be sept to you for <br /> distribution to the appropriate regulatory agencies. <br />
