<br /> Notes:
<br /> ppm . parts per million
<br /> TPH = total petroleum hydrocarbons
<br /> ND, = target analyte not detected above"x"method detection limit
<br /> 5.3, = concentration detected at"x"method detection limit
<br /> NT = not tested
<br /> BPS = below pile surface
<br /> = weathered diesel
