In these <br /> situations, to demonstrate precision and accuracy at a batch level, a LCS/LCSD was performed, unless otherwise <br /> specified in the method. <br /> All Inorganic Initial Calibration and Continuing Calibration Blanks met acceptable method criteria unless <br /> otherwise noted on the Analysis Report. <br /> Laboratory Compliance Quality Control <br /> Blank Blank Blank Report LCS LCSD LCS/LCSD <br /> Analysis Name Result LOQ** MDL Units %REC %REC Limits RPD RPD Max <br /> Batch number: C123532AA Sample number(s) : 6896681-6896684 <br /> Benzene N.D. 0.5 0.1 ug/l 101 99 80-120 2 30 <br /> Ethylbenzene N.D. 0.5 0.1 ug/l 101 98 80-120 3 30 <br /> Toluene N.D. 0.5 0.1 ug/l 97 95 80-120 2 30 <br /> Xylene (Total) N.D. 0.5 0.1 ug/l 97 94 80-120 2 30 <br /> Batch number: 12352WAD026 Sample number(s) : 6896682-6896684 <br /> Acenaphthene N.D. 0.0090 0.0030 ug/l 86 66* 68-116 27 30 <br /> Acenaphthylene N.D. 0.0050 0.0020 ug/l 96 71 69-126 30 30 <br /> Anthracene N.D. 0.0060 0.0030 ug/l 95 71 68-122 29 30 <br /> Benzo(a)anthracene N.D. 0.0090 0.0030 ug/l 89 67* 80-119 28 30 <br /> Benzo(a)pyrene N.D. 0.0090 0.0030 ug/l 91 68 38-127 28 30 <br /> Benzo(b)fluoranthene N.D. 0.0090 0.0030 ug/l 94 71 34-136 28 30 <br /> Benzo(g,h,i)perylene N.D. 0.012 0.0040 ug/l 111 82 56-135 30 30 <br /> Benzo(k)fluoranthene N.D. 0.0090 0.0030 ug/l 90 67 37-130 30 30 <br /> Chrysene N.D. 0.0050 0.0020 ug/l 86 65 65-122 28 30 <br /> Dibenz(a,h)anthracene N.D. 0.0090 0.0030 ug/l 113 84 60-138 30 30 <br /> Fluoranthene N.D. 0.0060 0.0030 ug/1 94 70 67-133 29 30 <br /> Fluorene N.D. 0.0060 0.0030 ug/l 89 67* 72-133 28 30 <br /> Indeno(1,2,3-cd)pyrene N.D. 0.012 0.0040 ug/1 114 84 55-149 30 30 <br /> 1-Methylnaphthalene N.D. 0.012 0.0040 ug/1 83 61* 64-121 30 30 <br /> 2-Methylnaphthalene N.D. 0.012 0.0040 ug/1 81 59 48-117 31* 30 <br /> Naphthalene N.D. 0.0090 0.0030 ug/1 85 63* 68-100 30 30 <br /> Phenanthrene 0.0039 J 0.0090 0.0030 ug/l 86 64* 71-124 29 30 <br /> Pyrene N.D. 0.0090 0.0030 ug/1 85 65* 71-114 27 30 <br /> Batch number: 123540011A Sample number(s) : 6896682-6896684 <br /> TPH-DRO water C10-C25 N.D. 100. 32 ug/1 86 88 54-122 2 20 <br /> Surrogate Quality Control <br /> Surrogate recoveries which are outside of the QC window are confirmed <br /> unless attributed to dilution or otherwise noted on the Analysis Report. <br /> Analysis Name: VOCs 25 ml purge 8260 <br /> Batch number: C123532AA <br /> Dibromofluoromethane 1,2-DichloroethaneA4 Toluene-d8 4-Bromofluorobenzene <br /> 6896681 109 103 102 100 <br /> *-Outside of specification <br /> **-This limit was used in the evaluation of the final result for the blank <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 /> Page 10 of 13 <br />
