(Condor) conducted groundwater <br /> monitoring and remediation activities at the above-referenced site (Site), consisting of diesel skimming <br /> operations and a quarterly-monitoring event. This report.contains a summary of the fourth quarter 2005 <br /> diesel product removal data and results of the fourth quarter 2005 groundwater monitoring, event <br /> conducted on November 8 and 9, 2005. Report attachments include diagrams indicating the Site location <br /> (Figure 1) and groundwater gradient (Figure 2); Site background information; historic monitoring and <br /> diesel product removal data; field forms; and laboratory analytical results. This report has been submitted <br /> to the CRWQCB and the SJCEHD as indicated above. <br /> Summary of Diesel Skimming Operations (August 26,2005 through November 9 2005) <br /> Six diesel recovery and skimmer operations and maintenance (0/M) events were conducted at the Site <br /> from August 26, 2005 through November 9, 2005. Free product was observed in four recovery wells <br /> (RW-2, RW-3,RW-4, and RW-6). A total of approximately 5.19 gallons of product was recovered during <br /> the monitoring and recovery period. Product recovery from the Site's recovery wells has produced a <br /> cumulative total of approximately 148.85 gallons of recovered diesel'. <br /> A new method for estimating product volumein the product recovery tank was instituted during the August 26, <br /> 2005 diesel recovery event to increase reporting consistency(see field forms). It resulted in a downward revision of <br /> 0.70 gallons to the previous recovery event product recovery tank volume(8/18/05) and a subsequent decrease to the <br /> cumulative overall recovered diesel total. Specifically the cumulative total of recovered diesel from recovery well <br /> RW-4 decreased by 0.70 gallons and the cumulative product recovery total for the period ending August 18, 2005 <br /> was revised from 144.36 down to 143.66 gallons. <br /> Is <br /> �a CONDOR <br />
