All onsite work was performed in accord with WESTON's site specific Health & Safety <br /> Plan, which was available onsite during field activities. A tailgate safety meeting was held <br /> with personnel prior to starting work to review anticipated safety hazards and emergency <br /> response procedures. The field work for this project was performed under Level D <br /> personal protection. <br /> 3.0 ANALYTICAL RESULTS <br /> The samples collected on May 20, 1991 were analyzed for Total Petroleum Hydrocarbons <br /> as Gasoline (TPH-G) by EPA Method 8015 (modified) and for Benzene, Toluene, <br /> Ethylbenzene and Xylene (BTEX) by EPA Method 8020. Table 1 summarizes the <br /> analytical results and Appendix A presents the complete analytical data package. <br /> TABLE 1 J '/may` _ ¢ <br /> Soil Sample Analytical Results C 6 <br /> N�IRONAA . y 1981 <br /> Sample EPA 8020 mg/Kg (ppm) EP 8(Yl�c /� �1F�tT <br /> I.D.
