Soil Sampling for StockpiledISoil <br /> 11 <br /> Soil samples were collected by advancing 2-inch diameter brass sample liners into the <br /> soil stockpile;'after removing approximately 6 inches to 1 foot of surface material in the <br /> sample location. One composite sample was collected per approximately 100 cubic-yards <br /> of soil. Soil samples for chemical analysis were retained in the brass liners, labeled, and <br /> capped with Teflon sheets and plastic end caps. The samples were then sealed in zip-lock <br /> bags, placed on ice, and transported to the laboratory accompanied by the appropriate <br /> chain-of-custody documentation. <br /> Laboratory Procedures <br /> Selected soil and groundwater samples collected will be analyzed for the presence of <br /> TPHg, benzene, toluene, ethylbenzene, and xylenes using modified EPA Methods 8015 <br /> and 8020, and fuel oxygenates by EPA Method 8260. <br /> Soil Cuttings and Purge Water <br /> Soil cuttings generated during drilling operations will be temporarily stored on site and <br /> covered with plastic sheeting pending characterization and disposal. Soil cuttings will be <br /> removed by a California-certified disposal contractor to an appropriate disposal facility. <br /> Water .generated during steam cleaning and development of the new wells will be <br /> temporarily stored in DOT-approved 55-gallon drums pending transport by the disposal <br /> contractor to an appropriate disposal or treatment facility. <br /> 4, <br /> IJ <br /> r <br /> I:ARCD5450\workplans\site contamination wkpin.doc <br />
