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' r . <br /> certified laboratory. The samples will also be analyzed for oxygenated fuel additives Methyl <br /> tertButyl Ether (MTBE), Tertiary Amyl Methyl Ether (TAMS), di-Isopropyl Ether (DIPE), <br /> Ethyl tert-Butyl Ether WBB), tert-Butanol, and ethanol using TPA 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 itg/L, TAME-5 Ng/L, <br /> DIPE - 5 m& BTBB - 5 µg/L, tert-Butanol - 100 µgl_L, ethanol - 500 pg/L, and methanol <br /> 1 Proposed detection limits for the ox Ajel chemical — ounds in soil are as <br /> 5 <br /> follows, E - 0.1 mg/kg, TAMS - 01 mg/kg, DIPB - 01 mg/kg, ETBE - 0 1 , tert- <br /> Butanol-5 0 mg/kg,ethanol-25 mg/kg,and methanol- 10 mg/kg <br /> »^ Ground Water Aqu(fer Testing: Cambna will perform an aquifer pumping test on proposed <br /> well MVV-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 /> • <br /> 3 <br />
