<br /> NOTES
<br /> TPH-gasoline analysis performed using California LUIFT Methodology(October 1989)
<br /> TPH-diesel analysis performed using California Tri-Regional Methodology
<br /> Method 5030(purge and trap)is used for gasoline sample preparation/introduction
<br /> Method 3550(sontcation)or Method 3510(separatory funnel liqutd-liquid)is used for diesel/motor oil sample extraction/preparation
<br /> EPA Method 8260 used for Volatile Organics-TCL analysis
<br /> EPA Method 8020 used for benzene,toluene,ethylbenzene,and total xylenes(BTEX)analysis
<br /> Bolded values exceed Industrial Soil PBGs
<br /> *-The hydrocarbon pattern present in these samples represents an unknown mixture atypical of gasoline in the range n-007 to n-C12
<br /> **-The hydrocarbon pattern present in these samples represents an unknown mixture atypical of diesel fuel or motor oil in the range
<br /> of n-008 to n-C40 Quantitation is based on a diesel reference between n-C10 an n-C24 only
<br /> NA-Not Analyzed
<br /> ND-Parameter not detected above laboratry reporting limits
<br /> <=Analyte not detected at reporting limit shown
