They were analyzed for: <br /> • BTEX by EPA method 8020 <br /> • TPH-G by EPA method 8015(m) <br /> • Total Extractable Petroleum Hydrocarbons as diesel, kerosene, motor oil (TEPH-D, K, <br /> MO)by EPA method 3540/8015 (m) <br /> • Chlorinated Solvents by method 8010 (truck maintenance yard only) <br /> • LUFT Metals by method 6010 (truck maintenance yard only) <br /> The detection limits for these compounds are listed below in the summary tables and are <br /> given on the lab reports attached in Appendix A. A Chain of Custody was completed for all <br /> samples collected and tracked to ensure sample integrity. <br /> Table 1: Soil Sample Analytical Data - November 5, 1999 <br /> Benzene Toluene Ethyl Total <br /> benzene Xylenes Gasoline Diesel Motor Oil <br /> ormg eP µg g µ g µg g µg g m g m m" g <br /> (198-03-03) <br /> �. <.. < , < .
