• <br /> Chemical Analysis: The soil and ground water samples will be analyzed for TPHg, benzene, <br /> toluene, ethyl benzene, and xylenes, (BTEX) by EPA Methods 8015/8020 at a California <br /> certified Iaboratory 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 8250 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 JXI L, TAME-5 µglL, <br /> DIPE - 5 H&LLjETBE - 5 µg/L, tert-Butanol - 100 µg/L, ethanol - 500 µg/L, and methanol <br /> 1 Proposedftetecti�onhrm�tsfor�the ��itlrhprntnal ounds in soil are as <br /> follows E - , 1 mg/kg, ETBE - 0 1 mglkg, tert- <br /> 5 Butanol-5.0 mg/kg,ethanol-25 mg/kg, and methanol- 10 mg/kg. <br /> Ground Water Aquifer Testing: Cambria will perform an aquifer pumping test on proposed <br /> well U %3 The aquifer pumping test will run for a total of approximately 12 hours Ground <br /> water will be extracted at a constant flow rate via an electric submersible pump Drawdown in <br /> the recovery well and surrounding wells will be taken periodically. Water extracted from the <br /> well will be stored onsite for disposal A ground water sample will be collected at the <br /> beginning, middle,and end of the test and analyzed as above <br /> 3 <br />
