Co. Group Number: 944093 <br /> Reported: 06/09/05 at 02:12 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: 05140WAGO26 Sample number(s) : 4527423,4527426,4527428 <br /> Naphthalene N.D. 0.01 ug/l 96 98 61-121 2 30 <br /> Acenaphthylene N.D. 0.02 ug/l 93 96 65-119 3 30 <br /> Acenaphthene N.D. 0.01 ug/l 93 98 62-112 4 30 <br /> Fluorene N.D. 0.01 ug/l 100 102 64-134 2 30 <br /> Phenanthrene N.D. 0.01 ug/l 96 97 63-139 1 30 <br /> Anthracene N.D. 0.02 ug/l 92 97 57-117 5 30 <br /> Fluoranthene N.D. 0.01 ug/l 99 103 61-131 4 30 <br /> Pyrene N.D. 0.02 ug/l 91 88 67-129 4 30 <br /> Benzo(a)anthracene N.D. 0.02 ug/l 95 96 64-120 1 30 <br /> Chrysene N.D. 0.02 ug/l 98 98 63-139 1 30 <br /> Benzo(b)fluoranthene N.D. 0.02 ug/l 108 105 69-128 3 30 <br /> Benzo(k)fluoranthene N.D. 0.01 ug/l 105 106 68-124 1 30 <br /> Benzo(a)pyrene N.D. 0.02 ug/l 95 97 66-123 2 30 <br /> Indeno(1,2,3-cd)pyrene N.D. 0.02 ug/l 107 102 72-125 5 30 <br /> Dibenz(a,h)anthracene N.D. 0.02 ug/l 88 85 48-128 3 30 <br /> Benzo(g,h,i)perylene N.D. 0.02 ug/l 111 104 65-125 6 30 <br /> Batch number: 05142AO8B Sample number(s) : 4527429 <br /> TPH-GRO - Waters N.D. 50. ug/l 101 103 70-130 2 30 <br /> Batch number: 05142AO8C Sample number(s) : 4527423,4527426,4527428 <br /> TPH-GRO - Waters N.D. 50. ug/l 101 103 70-130 2 30 <br /> Batch number: 051430016A Sample number(s) : 4527423,4527426,4527428 <br /> TPH-DRO CALUFT(Waters) N.D. 50. ug/l 81 88 64-125 7 20 <br /> Batch number: 05144SLD026 Sample number(s) : 4527422,4527424-4527425,4527427,4527430-4527433 <br /> Naphthalene N.D. 1. ug/kg 75 58-114 <br /> Acenaphthylene N.D. .0003 mg/kg 88 43-122 <br /> Acenaphthene N.D. 0.3 ug/kg 87 58-114 <br /> Flucrene N.D. .0003 mg/kg 97 59-124 <br /> Phenanthrene N.D. .0007 mg/kg 95 55-128 <br /> Anthracene N.D. .0003 mg/kg 97 55-122 <br /> Flucranthene N.D. .0007 mg/kg 100 55-132 <br /> Pyrene N.D. .0007 mg/kg 95 53-131 <br /> Benzo(a)anthracene N.D. .0003 mg/kg 99 53-125 <br /> Chrysene N.D. .0003 mg/kg 100 55-131 <br /> Benzo(b)fluoranthene N.D. .001 mg/kg 107 53-156 <br /> Benzo(k)fluoranthene N.D. .0007 mg/kg 104 61-140 <br /> Benzo(a)pyrene N.D. .0007 mg/kg 103 57-132 <br /> Indeno(1,2,3-cd)pyrene N.D. 0.3 ug/kg 101 64-148 <br /> Dibenz(a,h)anthracene N.D. .0007 mg/kg 83 59-151 <br /> Benzo(g,h,i)perylene N.D. .0003 mg/kg 105 61-143 <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 />
