1 <br /> ' Level (RWQCB Res. ESL). Soil Samples CT-MW-9-120 (85-86.5) and CT-MW-9-120 (100- <br /> 101.5) had detections of benzene of 0.18 and 0.15 ppm, respectively. Two other samples <br /> between these depths had concentrations of benzene detected above the MDL but below the <br /> RWQCB Res. ESL. Soil Sample CT-MW-9-120 (85-86.5) also had a concentration of <br /> ' xylenes detected above the laboratory MDL but below the RWQCB Res. ESL. <br /> Results of groundwater samples collected on July 22, 2009 indicate that groundwater in the <br /> well CT-MW-8-87 is impacted by TPH-g at 290 µg/L. Benzene concentration in this well <br /> was detected just above reporting limits. Minor concentrations of MTBE and TBA were also <br /> detected. Groundwater samples collected on this date from well CT-MW-9-120 also <br /> indicated low level TPH-g and benzene concentrations. Minor concentrations of DIPE and <br /> TBA were also detected. Samples collected in October 2009 from these wells were similar <br /> except that benzene was not detected in well CT-MW-8-87 and TPH-g was not detected in <br /> ' well CT-MW-9-120. <br /> 1 <br /> Monitoring Well Installation <br /> and <br /> BioSparge Evaluation Report <br /> ' Prepared For:Sara Lee Bakery Group,Inc. 12 Prepared By:PSC Industrial Outsourcing,LP <br /> Sam Lee—Lincoln Street 2009_12_03-MW Installation&BmSparge Evaluation Report(Fnal).dac Report Date:December 3,2009 <br />
