An OVA will be used to detect the presence or absence of VOCs in the <br /> soil samples and help determine which saturated sail samples will be <br /> analyzed. If the OVA detects hydrocarbons in unsaturated soil, the SJLHD may <br /> require analysis of soil samples from the interval where the positive readings <br /> were noted. If this is necessary, WA will provide a cost estimate for the <br /> additional analysis. <br /> Four-inch diameter ground water monitoring wells will be installed in the <br /> three boreholes. Wells will be screened at least 5 ft above the water table <br /> to allow for seasonal water table fluctuations. Appropriate disposal of drill <br /> cuttings will be determined by analysis of soil samples collected during <br /> drilling. For purposes of estimating costs, the attached budget assumes the <br /> cuttings are non-hazardous. If analysis Of the borehole samples indicates <br /> that the cuttit,gs are a hazardous waste, WA will prepare a cost estimate for <br /> nppropriate disposal. <br /> TASK 2 - WELL DEVELOPMENT, SA14PLING AND CHEMICAL ANALYSIS <br /> The monitoring wells will be developed by airlift evacuation with <br /> development water directed to a portable Baker tank temporarily stored <br /> r on-site. After development, one water sample will be collected from each well <br /> and from the Baker tank. The samples will be refrigerated And delivered to an <br /> analytinal laboratory under chain-of-custody procedures_ The ground water and <br /> develDpment water samples will be analyzed by GC/FID/photo ionization <br /> detection (PID) for TRIC and BTX. The development water will be disposed of <br /> appropriately depending on analytic results. <br /> Costs for potential disposal of the development water or drill cuttings <br /> as a hazardous waste are not included in this proposal. 1 <br /> e <br /> • <br /> _... arwmw1e���+m�e��ei.'ra�7ti�i7ffiR'ell�r- <br />
