<br /> NOTES
<br /> Benzene,toluene,ethylbenzene,xylenes analyzed by EPA 8020/8260 A = Acetone
<br /> Gasoline OxN genate Additives analyzed by EPA 8260 B = n-Butyl benzene
<br /> TPHg = Total Petroleum Hydrocarbons as gasoline(EPA 8015m) C = sec-Butyl benzene
<br /> TPHd = Total Petroleum Hvdrocarbons as diesel(EPA 8015m) D = tert-Butyl benzene
<br /> TRPH = Total Recoverable Petroleum Hvdrocarbons(EPA418 115520) E = 1,2-Dichlorobenzene
<br /> VOCs = Volatile Organic Constituents(EPA 8260) F = 1,4-Dichlorobenzene •
<br /> < — Not detected at reported detection limit G = Isopropylbenzene
<br /> ND = Not detected(detection limit Hanes,see laboratory report) H = Methyl butNl ketone
<br /> a = HeaN ier gasoline range compounds are significant(aged gasoline?) I — Methyl isobutyl ketone
<br /> b = No recognizable pattern J — Naphthalene
<br /> c = Lighter than uuter immiscible sheen is present K = n-Propyl benzene
<br /> d — Liquid sample that contains greater than—5 vol %sediment L = 1,2,3-Tnchloropropane
<br /> e = Unmodified or%%eakly modified gasoline is significant M = 1,2,4-Tnmethylbenzene
<br /> f = Gasoline range compounds are significant N = 1,3,5-Tnmethylbenzene
<br /> g = Unmodified or%%eakly modified diesel is significant P = Chlorobenzene
<br /> h = Oil range compounds are significant Q = 1,3-Dichlorobenzene
