TPHg=Total petroleum hydrocarbons-as-gasoline TAME=Tertiary-amyl-methyl ether <br /> It bgs=Feet Below Ground Surface MtBE=Methyl-tert-butyl ether TBA=Tertiary Butanol <br /> mg/kg=milligrams per kilogram or parts-per-million DIPE=Di-isopropyl ether <br /> J=TBA results may be biased slightly high;a fraction of MTBE(typically less than 1%)converts to TBA during the analysis. Laboratory considers this conversion effect to be mathmatically significant in <br /> samples that contain MTBErrBA in ratios of over 20:1. <br /> 7-Eleven\32262\Tables\32262 AnalyticalTables.xls Page 1 of 1 <br />
