AGE-NC Project No 99-0624 <br /> Page 2 of 2 <br /> analytical laboratory The samples were analyzed for <br /> • Fuel additives di-Isopropyl ether (DIPS), ethyl tertiary-butyl ether(ETBE), methyl tertiary- <br /> butyl ether (MTBE), tertiary-amyl methyl ether {TAME), tertiary butanol (TBA) In <br /> accordance with EPA Method 8260B <br /> Based on analytical results of the above referenced grab water samples, MTBE was detected from <br /> MW-2 on all four occasions at concentrations between 23,000 µg/1 and 84,000 µg/l, TAME was <br /> detected on all four occasions at concentrations between 46 [ig/1 and 180 µg/1 (MW-2), ETBE was <br /> detected on one occasion at a concentration of 2 4 µg/l No other constituents of concern were <br /> detected at or above laboratory reporting limits in the analyzed samples Analytical results of batch <br /> removal ground water samples are summarized in Table 2 The laboratory reports (CTEL Project <br /> Nos 0510-112, 0510-119, 0510-119 and 0510-134) and chain of custody forms are presented in <br /> Appendix A Confirmation pages of the laboratory electronic digital format (EDF) files submitted <br /> to the State of California's GeoTracker website are Included In Appendix B <br /> Between 18 and 21 October 2005, an estimated 107 pounds of MTBE was extracted from ground <br /> water (Table 3), the October 2005 batch removal mass-volume calculations of MTBE-Impact <br /> extracted from the ground water batch removal event are presented in Appendix C <br /> At the conclusion of the ground water batch removal event (21 October 2005), a total of 2,600 <br /> gallons of extracted ground water from MW-2 was transported off-site by American Valley Waste <br /> Oil,Inc to Cascade General Inc ,an EPA-approved waste water facility located in Portland,Oregon <br /> A copy of the non-hazardous waste manifest is Included in Appendix D If you have any questions <br /> or comments, please contact me at (209) 467-1006 <br /> r <br /> Sincerely, <br /> Advanced GeoEnvironrnental, Inc. <br /> No 7473 <br /> Timothy Cue lar William R Little <br /> Project Geologist Senior Project Geologist <br /> Enclosure California Professional Geolo 3 <br /> cc <br /> Mr Pete Graffigna, Flame Mini-Mart <br /> Mr Jim Barton, California Regional Water Quality Control Board - Central Valley Region <br /> i <br /> Advanced GeoEnhronmental,Inc <br />
