Co. Group Number: 1132170 <br /> Reported: 02/26/09 at 02:46 PM <br /> Matrix QC may not be reported if site-specific QC samples were not <br /> submitted. In these situations, to demonstrate precision and accuracy at <br /> a batch level, a LCS/LCSD was performed, unless otherwise specified in the <br /> method. <br /> Laboratory Compliance Quality Control <br /> Blank Blank Report LCS LCSD LCS/LCSD <br /> Analysis Name Result Procrram Units %REC %REC Limits RPD RPD Max <br /> RL <br /> Batch number: 090450005A Sample number(s) : 5599733-5599737 <br /> TPH-DRO water C10-C25 N.D. 50. ug/l 79 85 57-118 8 20 <br /> Batch number: 09045WAGO26 Sample number(s) : 5599733-5599737 <br /> Naphthalene N.D. 0.05 ug/l 85 68-100 <br /> Acenaphthylene N.D. 0.01 ug/l 112 69-126 <br /> Acenaphthene N.D. 0.01 ug/l 104 68-116 <br /> Fluorene N.D. 0.01 ug/l 109 49-145 <br /> Phenanthrene N.D. 0.01 ug/l 102 71-124 <br /> Anthracene N.D. 0.01 ug/l 103 68-122 <br /> Fluoranthene N.D. 0.01 ug/l 99 67-133 <br /> Pyrene N.D. 0.01 ug/l 97 68-128 <br /> Benzo(a)anthracene N.D. 0.01 ug/l 108 80-119 <br /> Chrysene N.D. 0.01 ug/l 104 80-124 <br /> Benzo(b)fluoranthene N.D. 0.01 ug/l 116 75-123 <br /> Benzo(k)fluoranthene N.D. 0.01 ug/l 108 72-122 <br /> Benzo(a)pyrene N.D. 0.003 ug/l 110 70-118 <br /> Indeno(1,2,3-cd)pyrene N.D. 0.01 ug/l 118 66-136 <br /> Dibenz(a,h)anthracene N.D. 0.003 ug/l 120 60-138 <br /> Benzo(g,h,i)perylene N.D. 0.01 ug/l 114 58-138 <br /> Batch number: 090540035A Sample number(s) : 5599734-5599737 <br /> TPH-DRO water C10-C25 w/Si Gel N.D. 32. ug/l 44* 45 45-114 3 20 <br /> Sample Matrix Quality Control <br /> Unspiked (UNSPK) = the sample used in conjunction with the matrix spike <br /> Background (BKG) = the sample used in conjunction with the duplicate <br /> MS MSD MS/MSD RPD BKG DUP DUP Dup RPD <br /> Analysis Name %REC %REC Limits RPD MAX Conc Conc RPD Max <br /> Batch number: 090450005A Sample number(s) : 5599733-5599737 UNSPK: 5599734 <br /> TPH-DRO water C10-C25 -11* -114* 59-128 37* 20 <br /> Batch number: 09045WAGO26 Sample number(s) : 5599733-5599737 UNSPK: 5599734 <br /> Naphthalene 106* 90* 70-86 16 30 <br /> Acenaphthylene 114* 120* 69-111 5 30 <br /> Acenaphthene 112* 116* 64-110 4 30 <br /> Fluorene 98 106 50-122 8 30 <br /> Phenanthrene 85 85 70-114 0 30 <br /> Anthracene 136 122 10-151 11 30 <br /> Fluoranthene 108 106 63-121 1 30 <br /> *-Outside of specification <br /> (1)The result for one or both determinations was less than five times the LOQ. <br /> (2)The unspiked result was more than four times the spike added. <br />
