<br /> Noter
<br /> #&4=parts per billion
<br /> TPH-g=total petroleum hydrocarborLs quantified as gasoline
<br /> TPH-d total petroleum hydrocarbon.,quantified as diesel
<br /> MTBE=methyl tertiary butyl ether
<br /> although within the diesel range for hydrocarbons,this sample is more represent-Itive of gasoline
