This <br /> process will be repeated until the boring is filled to the ground surface. � <br /> 4.5 Laboratory Analysis F <br /> l <br /> 16 k <br /> Selected soil and ground water samples may be analyzed by'the folIllowing analytical methods: i <br /> r <br /> i <br /> TPH-D by EPA Method 8015 Modified; <br /> F <br /> TPH-G by EPA Method 8015 Modified; <br /> * BTEX by EPA Method 8020; and <br /> * CAM metals by EPA 6000/7000 Series Methodology. <br />� t <br /> Additionally, one trip blank will be prepared by the laboratory and will accompany the <br /> ground water samples during transport to the laboratory to assess the potential for cross- <br /> contamination. The trip blank will be submitted to the laboratorY for BTEX analysissis only. <br /> 4.6 Field Management Procedures <br /> � l <br /> Drilling and sampling equipment will be cleaned prior to arrival on site and before leaving <br /> the site. To minimize the potential for cross-contamination, downhole equipment will be <br /> steam cleaned between each boring. Soil cuttings generated during the investigation will be <br /> placed in labeled Department of Transportation drums and t 4�anspo. ed to Forward Landfill, <br /> I <br /> in Stockton, California, for interim storage. Upon receipt of borehole analytical results, it is <br /> anticipated that the soil will be disposed of at the Forward Landfill. <br /> f <br /> I <br /> IN l <br /> i <br /> I 808-OOl.wkp/03-14-97lu/keyda[a/workplan 1 1 k <br /> � E <br />
