Box 6012, Room K-2016 <br /> Discard: 01/05/2004 San Ramon CA 94583-0712 <br /> 2858- SDG#: OVP22-03 <br /> As Received <br /> CAT As Received Method Dilution <br /> No. Analysis Name CAS Number Result Detection Units Factor <br /> Limit <br /> 02729 Custom TPH with Ranges (soil) <br /> 02730 Total TPH n.a. 3,100. 80. mg/kg 20 <br /> 05011 C10-C36 n.a. 3,100. 80. mg/kg 20 <br /> TPH was detected in the method blank associated with this sample. Since the <br /> TPH concentration in the sample is more than 5 times the blank value, the data <br /> is reported. <br /> i <br /> Accurate surrogate recoveries could not be determined due to the dilution <br /> required for analysis of the sample. <br /> Sufficient sample volume was not available to perform a MS/MSD for this <br /> analysis. Therefore, a LCS/LCSD was performed to demonstrate precision and <br /> accuracy at a batch level. <br /> 05878 BTEX <br /> 02174 Benzene 71-43-2 N.D. 0.05 mg/kg 250 <br /> 02177 Toluene 108-88-3 0.1 0.05 mg/kg 250 <br /> 02178 Ethylbenzene 100-41-4 0.4 0.05 mg/kg 250 <br /> 02182 Total Xylenes 1330-20-7 2.6 0.2 mg/kg 250 <br /> The analysis for volatiles was performed on a sample which was preserved <br /> in methanol. The reporting limits were adjusted appropriately. <br /> A poor surrogate recovery was observed due to the dilution needed to <br /> perform the analysis. <br /> Due to the presence of an interferent near its retention time, the normal <br /> reporting limit was not attained for benzene. The <br /> presence or concentration of this compound cannot be determined due to the <br /> presence of this interferent. <br /> 02858 Selected SVOA's in soil by SIM <br /> 02863 Naphthalene 91-20-3 0.053 0.001 mg/kg 1 <br /> 02867 Acenaphthylene 208-96-8 N.D. 0.0003 mg/kg 1 <br /> 02868 Acenaphthene 83-32-9 0.17 0.0003 mg/kg 1 <br /> 02870 Fluorene 86-73-7 0.31 0.0003 mg/kg 1 <br />
