Chemical Analysis: The soil and ground water samples will be analyzed for TPHg, benzene, <br /> Itoluene, ethyl benzene, and xylenes, (BTEX) by EPA Methods 8015/8020 at a California <br /> certified laboratory The samples will also be analyzed for oxygenated fuel additives Methyl <br /> tert-Butyl Ether (MTBE), Tertiary Amyl Methyl Ether (TAME), di-Isopropyl Ether (DIPE), <br /> Ethyl tert-Butyl Ether (ETBE), tert-Butanol, and ethanol using EPA Method 8260 Methanol <br /> will be analyzed by EPA Method 8015 (modified) Proposed detection limits for the <br /> oxygenated fuel chemical compounds in water are as follows MTBE - 5 gg/L, TAME - 5 µg/L, <br /> DIPE - 5 gg/L, ETBE - 5 gg/L, tert-Butanol - 100 gg/L, ethanol - 500 gg/L, and methanol — <br /> 1 mg/L Proposed detection knits for the oxygenated fuel chemical compounds in soil are as <br /> follows MTBE - 0 1 mg/kg, TAME - 0 1 mg/kg, DIPS - 0 1 mg/kg, ETBE - 0 1 mg/kg, tert- <br /> Butanol -5 0 mg/kg,ethanol -25 mg/kg,and methanol - 10 mg/kg <br /> 1 <br /> I <br /> I <br /> { <br /> 1 <br />
