i <br /> presence of petroleum hydrocarbons using a portable photoionization detector (PID), as well as <br /> by observing and smelling the material for field-evident petroleum hydrocarbon contamination. <br /> Soil cuttings will be placed in DOT-approved 55 -gallon steel drums, properly labeled and left <br /> onsite pending laboratory results. . <br /> For the scope of this work, the investigation will continue to a depth of 50 feet and until two (2) <br /> consecutive samples do not show contamination by field measures, with soil sampling at 5 foot <br /> intervals starting at 15 feet below grade. A minimum of four (4) samples will be selected for <br /> analysis for TPHg, TPHd, TPHo, BTEX and MTBE/oxygentates, at least two (2) of which will <br /> be from the saturated zone. In addition, a groundwater sample will be secured for analysis for <br /> TPHg, TPHd, TPHo, BTEX and MTBE/oxygenates. <br /> Groundwater samples will be obtained in a precleaned bailer, secured in 40 mL volatile organic <br /> analysis vials, placed in a cooler with wet ice and delivered to a State certified laboratory with a <br /> chain of custody documents. <br /> Boring B-6 and B-7 will be back filled with neat cement applied by standard procedures and <br /> used by experienced drilling contractors. A registered geologist or civil engineer will supervise <br /> all operations. <br /> 8. 0 LABORATORY ANALYSIS <br /> After extraction, the soil and water samples will be analyzed for total petroleum hydrocarbons as <br /> diesel, oil and gasoline (TPHg, TPHd and TPHo) by EPA Method 8015 . The groundwater <br /> samples will also be analyzed for benzene, toluene, ethylbenzene and total xylenes (BTEX) by <br /> EPA Method 8020, and Methyl tert-Butyl Ether (MTBE)/oxygenates by EPA Method 8260 . The <br /> soil samples will be analyzed for benzene, toluene, ethylbenzene and total xylenes (BTEX) by <br /> EPA Method 8020, and Methyl tert-Butyl Ether (MTBE)/oxygenates by EPA Method 8260. <br /> 9.0 REPORT PREPARATION <br /> Section unchanged from the Work Plan dated 1 May 2000. <br /> 10. 0 HEALTH AND SAFETY <br /> Section unchanged from the Work Plan dated I May 2000 . <br /> Environeering, Inc.
