i 15 January 2001 AGE-NC Project Na 96-0232 Page 9 of 20 The results of the laboratory analysis did not detect any constituents of concern above laboratory reporting limits The laboratory report (McCampbell Analytical Inc Lab I D 54621) and chain-of- custody hain-ofcustody form is presented in Appendix G 6 2 START-UP GRAB WATER SAMPLING PROCEDURES ' During the pump and treat start-up period, ground water influent and processed water effluent, depth to ground water measurements and operational parameters (ground water flow meters, fluid level sensors, total flow indicators) were monitored daily during the start-up period to ensure optimal removal of dissolved hydrocarbons and dissolved MTBE Grab ground water samples were collected from influent and effuent sampling ports and logged on a chain-of-custody form, placed in a chilled ' container and transported to a California Department of Health Services (DHS)-certified laboratory for analysis for the following analytes ' • TPH-g and TPH-d by EPA Methods 8015M/5030 and 8015M/3550, respectively, • BTEX with MTBE by EPA Method 8020, and ' o TBA, DIPE, ETBE, TAME, methanol, ethanol and MTBE by EPA Method 8260M ' 63 START-UP GRAB WATER ANALYTICAL RESULTS ' Analysis of influent grab water samples collected on 09, 10, 13, 14, 16, 17 and 20 November 2000 detected MTBE at concentrations between 290 and 1,100µg11 utilizing EPA Methods 8020 and 8260 ' Modified TPH-g was detected in three influent water samples at concentrations of 51, 59 and 62 ,ugll on 09, 13 and 16 November 2000, respectively, TPH-d was detected in one grab water sample at a concentration of 76 µg11 collected on 16 November 2000 None of the other analytes were ' detected in the influent water samples above laboratory reporting limits during the start-up period Effluent grab water samples collected on 09, 10, 13, 14, 16, 17 and 20 November 2000 did not detect ' any of the above mentioned analytes at concentrations above laboratory reporting limits The analytical results from the influent and effluent grab water samples are summarized In Table 2 The laboratory report and chain-of-custody forms are presented in Appendix F 1 64 START-UP PUMP AND TREAT WATER DISPOSAL ' Approximately 31,750 gallons of extracted water were generated during the start-up period(Table 1) On 10, 13, 14, 15, 16, 18 and 21 November 2000, start-up processed water was pumped from the ' Advanced GeoEnvcronmentai,Inc
