The sampler will be driven <br /> approximately 8 inches. <br /> Soil samples will be identified and described according to the <br /> Unified Soil Classification System. Their will be subjectively <br /> analyzed for presence of hydrrrLarbon odor and subjected to <br /> hydrocarbon.vapor measurement with an .arganic vapor. analyzer or <br /> 4 <br /> equivalent prior to preparation for transport to the laboratory. <br /> _ Selected soil samples will be submitted to Applied Geosystems' Y <br /> certified laboratory for analysis by EPA Method 8020 for :total <br /> volatile hydrocarbons and volatile hydrocarbon constituents <br /> €. benzene, ethylbenzene, toluene, and total.xylenes, and by the <br /> modified EPA Method 801.5 for extractable hydrocarbons. The <br /> cuttings generated: from the drilling operations will be left on <br /> site for later disposal. Applied GeoSystems can arrange for the <br /> b <br /> suitable disposal of the soil with Beacon oil's authorization. <br /> 6 <br />
