<br /> Notes
<br /> ,ug11 micrograms per Mer or parts per billion
<br /> TPM-g total petroleum hydrocarbons quantified as gasoline
<br /> TPH-d total petroleum hydrocarbons quantified as diesel
<br /> MTBE methyl ternary butyl ether
<br /> NA not analyzed
<br /> NS not sampled
<br /> ND not detected
<br /> < indicates constituents were not detected at a concentration greater than the reporting limit shown
<br /> r although within the diesel range for hydrocarbons,the laboratory indicated this sample is more representative of gasoline
