Co. Group Number: 1105967 <br /> Reported: 09/07/08 at 12:24 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 Program Units %REC %REC Limits RPD RPD Max <br /> RL <br /> Batch number: 08232196601A Sample number(s) : 5444430 <br /> Chloride ND 200. ug/l 97 90-110 <br /> Sulfate ND 300. ug/l 101 89-110 <br /> Nitrate Nitrogen ND 50. ug/l 104 90-110 <br /> Nitrite Nitrogen ND 80. ug/l 103 90-110 <br /> Batch number: 08233108101B Sample number(s) : 5444430 <br /> Kjeldahl Nitrogen ND 500. ug/l 108 90-110 <br /> Batch number: 082340007A Sample number(s) : 5444430-5444431 <br /> TPH-DRO (C10-C25) Water ND 50. ug/l 74 83 57-118 11 20 <br /> Batch number: 08234021201A Sample number(s) : 5444430 <br /> Total Dissolved Solids ND 9700. ug/l 103 80-120 <br /> Batch number: 08234022101A Sample number(s) : 5444430 <br /> Ammonia Nitrogen ND 200. ug/l 96 91-100 <br /> Batch number: 08234110101A Sample number(s) : 5444430 <br /> Total Phosphorus as PO4 water ND 250. ug/l 93 90-110 <br /> Batch number: 082341848004 Sample number(s) : 5444430 <br /> Calcium ND 70.2 ug/l 103 90-112 <br /> Iron ND 52.2 ug/l 97 90-112 <br /> Magnesium ND 13.5 ug/l 97 89-110 <br /> Potassium ND 50.3 ug/l 103 88-119 <br /> Sodium 482 433. ug/l 97 80-120 <br /> Manganese ND .84 ug/l 97 90-110 <br /> Boron ND 9.4 ug/l 100 90-110 <br /> Batch number: 08234WAH026 Sample number(s) : 5444430-5444431 <br /> Naphthalene ND 0.05 ug/l 90 85 68-100 5 30 <br /> Acenaphthylene ND 0.01 ug/l 99 103 69-126 4 30 <br /> Acenaphthene ND 0.01 ug/l 108 114 68-116 5 30 <br /> Fluorene ND 0.01 ug/l 108 110 49-145 2 30 <br /> Phenanthrene ND 0.01 ug/l 109 104 71-124 4 30 <br /> Anthracene ND 0.01 ug/l 98 101 68-122 3 30 <br /> Fluoranthene ND 0.01 ug/l 112 112 67-133 0 30 <br /> Pyrene ND 0.01 ug/l 105 103 68-128 2 30 <br /> Benzo(a)anthracene ND 0.01 ug/l 100 95 80-119 5 30 <br /> Chrysene ND 0.01 ug/l 105 101 80-124 4 30 <br /> Benzo(b)fluoranthene ND 0.01 ug/l 93 94 75-123 2 30 <br /> Benzo(k)fluoranthene ND 0.01 ug/l 88 93 72-122 6 30 <br /> Benzo(a)pyrene ND 0.003 ug/l 89 98 70-118 10 30 <br /> Indeno(1,2,3-cd)pyrene ND 0.01 ug/l 93 94 48-165 1 30 <br /> Dibenz(a,h)anthracene ND 0.003 ug/l 90 92 60-138 2 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 />
