awF' �ar <br /> TPH-g, BTEX, and MTBE concentrations appear in Table 1, while oxygenates and alcohols <br /> concentrations are summarized in Table 2 Copies of laboratories reports are included in Appendix <br /> B The TPH-g, benzene, and MTBE isoconcentration maps are presented in Figures 2,3, and 4. <br /> TPH-g and benzene were below the laboratory detection limits for all constituents The only <br /> detectable concentration of MTBE was found in well MW-11 (1,460 ug/L) <br /> Since the third quarter of 1997,Thrifty has analyzed for the requested oxygenates di-isopropyl ether <br /> (DIPE),ethyl-tert butyl ethyl (ETBE),tert-amyl methyl ether(TAME), and tert-butanol (TBA), and <br /> MTBE by method 8260 The following alcohols were also requested for analysis Ethanol and <br /> Methanol For the Third Quarter 2000, the only oxygenate detected was MTBE at 1,460 ug/L (in <br /> well MW-11) No other oxygenates were detected above laboratory method detection limits <br /> Summary and Recommendations <br /> On December 7, 1999, the San Joaquin County Public Health Services, Environmental Health <br /> Division (PHS/EHD) approved The Corrective Action Plan (CAP), August 18, 1999) for this site <br /> Thrifty has selected Advanced GeoEnvironmental, Inc of Stockton, California (a contractor) to <br /> perform the remediation system installation The remedial installation activities include acquisition <br /> of all necessary permits, installation of gas and electrical service lines, delivery and hookup of the <br /> thermal oxidizer and groundwater treatment equipment, and start-up of the remedial system These <br /> activities have been initiated during the Third Quarter 2000, with system start-up expected by mid <br /> to late Fourth Quarter 2000 <br /> Thrifty will continue quarterly groundwater monitoring, gauging, purging and sampling of all <br /> groundwater monitoring wells <br /> All interpretations expressed in this report are based upon review of data collected by EMC <br /> Written by Reviewed by <br /> ED i;�CQ` <br /> d4 <br /> a and C Friedrichsen, REA 11 Larry Hi robot am OF cA�-�F� <br /> Project Manager, MBA Registered Geologist#5497 <br /> Senior Hydrogeologist <br /> i <br />
