Co. Group Number: 944279 <br /> Reported: 06/14/05 at 05:33 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 MDL Units %REC %REC Limits RPD RPD Max <br /> Batch number: 05142WAA026 Sample number(s) : 4528314,4528316 <br /> Naphthalene N.D. 0.01 ug/l 93 96 61-121 3 30 <br /> Acenaphthylene N.D. 0.02 ug/l 94 96 65-119 1 30 <br /> Acenaphthene N.D. 0.01 ug/l 95 96 62-112 1 30 <br /> Fluorene N.D. 0.01 ug/l 102 102 64-134 0 30 <br /> Phenanthrene N.D. 0.01 ug/l 97 98 63-139 1 30 <br /> Anthracene N.D. 0.02 ug/l 93 94 57-117 1 30 <br /> Fluoranthene N.D. 0.01 ug/l 102 103 61-131 1 30 <br /> Pyrene N.D. 0.02 ug/l 91 90 67-129 1 30 <br /> Benzo(a)anthracene N.D. 0.02 ug/l 98 96 64-120 1 30 <br /> Chrysene N.D. 0.02 ug/l 101 99 63-139 2 30 <br /> Benzo(b)fluoranthene N.D. 0.02 ug/l 103 105 69-128 2 30 <br /> Benzo(k)fluoranthene N.D. 0.01 ug/l 104 104 68-124 0 30 <br /> Benzo(a)pyrene N.D. 0.02 ug/l 93 95 66-123 2 30 <br /> Indeno(1,2,3-cd)pyrene N.D. 0.02 ug/l 105 102 72-125 3 30 <br /> Dibenz(a,h)anthracene N.D. 0.02 ug/l 87 86 48-128 2 30 <br /> Benzo(g,h,i)perylene N.D. 0.02 ug/l 109 106 65-125 3 30 <br /> Batch number: 051430016A Sample number(s) : 4528314,4528316 <br /> TPH-DRO CALUFT(Waters) N.D. 50. ug/l 81 88 64-125 7 20 <br /> Batch number: 051450021A Sample number(s) : 4528313,4528315,4528318-4528321 <br /> Total TPH N.D. 4.0 mg/kg 88 87 65-122 1 20 <br /> C10-C36 N.D. 4.0 mg/kg <br /> Batch number: 05145AO8A Sample number(s) : 4528316 <br /> TPH-GRO - Waters N.D. 50. ug/l 103 106 70-130 2 30 <br /> Batch number: 05145AO8B Sample number(s) : 4528314,4528317 <br /> TPH-GRO - Waters N.D. 50. ug/l 103 106 70-130 2 30 <br /> Batch number: 05146SLB026 Sample number(s) : 4528313,4528315,4528318-4528321 <br /> Naphthalene N.D. 1. ug/kg 96 58-114 <br /> Acenaphthylene N.D. 0.3 ug/kg 94 43-122 <br /> Acenaphthene N.D. 0.3 ug/kg 96 58-114 <br /> Fluorene N.D. 0.3 ug/kg 96 59-124 <br /> Phenanthrene N.D. 0.7 ug/kg 98 55-128 <br /> Anthracene N.D. 0.3 ug/kg 97 55-122 <br /> Fluoranthene N.D. 0.7 ug/kg 94 55-132 <br /> Pyrene N.D. 0.7 ug/kg 98 53-131 <br /> Benzo(a)anthracene N.D. 0.3 ug/kg 96 53-125 <br /> Chrysene N.D. 0.3 ug/kg 98 55-131 <br /> Benzo(b)fluoranthene N.D. 1. ug/kg 100 53-156 <br /> Benzo(k)fluoranthene N.D. 0.7 ug/kg 100 61-140 <br /> *-Outside of specification <br /> (1) The result for one or both determinations was less than five times the LOQ. <br /> (2) The background result was more than four times the spike added. <br />
