<br /> Notes.
<br /> p8ll micrograms per Mer or parts per billion
<br /> TPH-g total petroleum hydrocarbons quantified as gasoline
<br /> TPH-d total petroleum hydrocarbons quantified as diesel
<br /> MTBE methyl tertiary butyl ether
<br /> NA not analyzed,NS not sampled ND not detected
<br /> < indicates constituents were not detected at a concentration greater than the reporting limit shown
<br /> t although within the diesel range far hydrocarbons,the laboratory indicated this sample is more representative ofWalme
