The <br /> laboratory report(CTEL Lab Project.No.CT214-0910016),quality assurance/quality control report, <br /> and chain-of-custody form for the tank sample collected on 01 October 2009 are included in <br /> Appendix A. The analytical results of the holding tank sample are summarized below. <br /> Yamada Brothers <br /> 'Holding.Tank' Sample collected on 01 October 2009 <br /> TPH-g TPH-d MTBE Benzene Toluene Ethylbenzene Xylenes <br /> <50 µg/1 <50 gg/l <1. µg/l <0.5 µg11 <0.5 µg/1 <0.5 gg/l <0.6 gg/l <br /> Based upon the above analytical results, the stored ground water appears to present little threat to <br /> water quality if discharged to surface as a dust control measure.
