Groundwater elevations decreased approximately 0 43 feet from the previous <br /> event performed in May 2005 During this event, the average depth to <br />' groundwater in the wells was 26 76 feet bgs (-16 99 feet msl) The elevations <br /> ranged from -16 67 feet to -17 41 feet msl The groundwater flow direction is <br /> easterly at a gradient of approximately 0 005 foot per linear foot <br /> 1 <br /> 2.3 BTEX and TPH-G Analytical Results <br /> Xylenes were detected in the groundwater sample from well MW-2 Benzene, <br /> toluene, ethylbenzene, and TPH-G were not detected in the groundwater <br /> samples from well MW-2. BTEX and TPH-G were not detected in the <br /> samples collected from wells MW-1, MW-3, or MW-4 <br />' The current BTEX concentrations were compared to the California Drinking <br /> Water Maximum Contaminant Levels (MCLs) The MCLS in groundwater <br /> are benzene (1 }tg/L), toluene (150 µg/L), ethylbenzene (300 gg/L), and <br /> xylenes (1,750 µg/L) Based on the current groundwater monitoring data, <br /> none of the MCLS was exceeded in any of the samples <br />' 2.4 Oxygenates Analytical Results <br /> M Fuel oxygenates were not detected in any of the groundwater samples <br /> collected in July 2005 The oxygenate MTBE was evaluated against the <br /> California Drinking MCL The MCL in groundwater for MTBE is 13 gg/L <br />' Based on the current groundwater monitoring data, the MCL for MTBE was <br /> not exceeded in any of the samples <br /> 1 <br /> • <br /> t <br /> Quarterly Groundwater Monitoring Report <br /> July 2005 <br />' Prepared for SARA LEE BAKERY GROUP,INC Prepared by Philip Services Corporation <br /> Investigative and Quarterly Report\3rd Quarterly Report 07_2005(8nal) September 23,2005 <br />
