tr \. <br /> Report:Groundwater-quality Monitoring--July 14-15,2006, 7500 West Eleventh Street, Tracy, CA Page 16 <br /> k� <br /> Di-isopropyl ether EPA Method 8260B <br /> Ethyl tertiary-butyl ether EPA Method 8260B <br /> Tertiary-amyl methyl ether EPA Method 8260B <br /> 3.2 Monitoring and Management of Light Non-aqueous Phase Liquid <br /> Because over two years of monitoring for LNAPL in Monitoring Wells MWFP-1 through <br /> MWFP-5 has detected no floating product in those wells, the LNAPL-monitoring <br /> conducted in February 2007 shall be restricted to Monitoring Well MW-7 and that <br /> program scope will apply to future monitoring events unless there are unexpected and <br /> significant increases in the concentrations of analytes of concern in any of the nearby <br /> wells. As has been the case in the past, any LNAPL detected in Monitoring Well MW-7 <br /> will be purged from the well at the time that a groundwater sample is recovered from it. <br /> 3.3 Potable Water-quality Monitoring Program <br /> Consistent with the guidance provided the SJCEHD (San Joaquin County Environmental <br /> Health Department 2006), the next round of potable water monitoring at the Navarra Site <br /> will encompass recovery of samples from the wells at 7500 West Eleventh Street and <br /> 23901 South Chrisman Road and is scheduled for July 2007. The recovered samples of <br /> r-� potable water will be analyzed for the suite of analytes listed in Section 3.1, above. <br /> L <br /> L <br /> sic <br />
