<br /> NOTES
<br /> Benzene,toluene,ethylbenzene,xylenes analyzed by EPA 8020/8260 A = Acetone
<br /> Gasoline Oxygenate Additives analyzed by EPA 8260 B = n-Butyl benzene
<br /> TPHg = Total Petroleum Hydrocarbons as gasohne(EPA 8015m) C — sec-Butyl benzene
<br /> TPHd = Total Petroleum Hydrocarbons as diesel(EPA 8015m) D = tett-Butyl benzene
<br /> TRPH = Total Recoverable Petroleum Hydrocarbons(EPA4181/5520) E = 1,2-Dichlorobenzene
<br /> VOCs = Volatile Organic Constituents(EPA 8260) F = l,4-Dichlorobenzene
<br /> < = Not detected at reported detection limit G = I 1,4-Dichlorobenzene
<br /> ND = Not detected(detection Limit vanes,see laboratory report) H = Methyl butyl ketone
<br /> a — Heavier gasoline range compounds are significant(aged gasoline?) 1 = Methyl isobutyl ketone
<br /> b = No recognizable pattern J — Naphthalene c = Lighter than water immiscible sheen is present K = Naphtn-ProNaphtbenzene
<br /> d W Liquid sample that contains greater than--5 vol %sediment L — 42,3-Tnchloropropane
<br /> e — Unmodified or weakly modified gasoline is significant M — 1,2,4-Trimethylbenzene
<br /> f = Gasoline range compounds are significant N = 1,3,5-Tnmeihylbenzene
<br /> 9 = Unmodified or weakly modified diesel is significant P — Chlorobenzene
<br /> h = Oil range compounds are significant Q = 1,3-Dichlorobenzenei = Diesel range compounds are significant,no recognizable pattern R = trans-1,2-Dichloroethene
<br /> J — Result from EPA Method 8260 S — cis-1,2-Dichloroethene
