MTBE=Methyl tertiary butyl ether. <br /> <=Below detection limit for analytical methods used. DIPE=Di-isopropyl ether, <br /> NA=not analyzed. ETBE=Ethyl tertiary butyl ether. <br /> [1]This sample was analyzed outside EPA recommended holding time. TAME=Tertiary amyl methyl ether. <br /> [2]The opening calibration verification standard was outside acceptance 1,2-DCA= 1,2-Dichloroethane <br /> limits by<3%. Although the Lab Control Sample verified the accuracy of <br /> this batch,this should be considered in evaluating the data for its intended purpose. <br /> [3]The sample was diluted due to the presence of high levels of non-target analytes resulting in elevated reporting limits. <br /> Delta <br /> Arco_0548_Quarter1y_Data.XLS 2 of 2 <br />
