Groundwater elevations decreased approximately 1 73 feet from the previous <br /> event performed in April 2004 The elevations ranged from—19 25' to- <br /> 20 <br /> o- <br /> 20 15' MSL The groundwater flow direction is easterly at a gradient of <br /> approximately 5 66 x 10"3 feet per linear foot <br /> 2.3 BTEX and TPH-G Analytical Results <br />' Petroleum hydrocarbons of benzene, toluene, ethylbenzene, xylenes, and <br /> TPH-G were detected in the groundwater sample from well MW-2 However, <br /> the BTEX and TPH-G concentrations )increased from the previous event, due <br />' to temporarily disengaging the sparging system There were no detectable <br /> BTEX or TPH-G concentrations measured in the samples collected from wells <br /> MW-1, MW-3, and MW-4 <br /> The current BTEX concentrations were evaluated against the California <br /> Drinking Water Maximum Contaminant Levels (MCL)s The MCLs in <br /> groundwater are benzene (1 pg/L), toluene (150 pg/L), ethylbenzene (700 <br /> pg/L), and xylenes (1,750 Vtg/L) Based on the current groundwater <br /> monrtonng data, the MCLs for benzene and toluene have been exceeded in <br /> well MW-2 <br /> 2.4 Oxygenates Analytical Results <br /> The analyte TBA was the only oxygenate with detectable concentrations The <br /> analyte was detected in well MW-2 There were no detectable oxygenates <br /> measured in the remaining wells <br /> 1 <br /> 10 <br /> 1 <br /> August <br /> 2004 <br /> Quarterly Groundwater Monitoring Report <br />' Earthgrams Baking Companies,Inc <br /> (Former Kilpatrick's Bakeries,Inc) <br /> 1717 South Center Street <br /> Stockton,Callfomla <br /> Prepared for SARA GEE BAKERY GROUP Prepared by Philip Services Corp <br />�� H1ENV1524001325121382EWrotectslStocktonLenter SWrivesugative and Quarterly Reports\Quarterly Report 10_2004 doc January 18,2003 <br />
