The client was notified and approved proceeding with the extraction and analysis. Site-specific MS/MSD samples were not submitted for the project. A LCS/LCSD was performed to demonstrate precision and accuracy at a batch level. 05878 BTEX 02174 Benzene 71-43-2 N.D. 0.05 mg/kg 250 02177 Toluene 108-88-3 0.07 0.05 mg/kg 250 02178 Ethylbenzene 100-41-4 0.2 0.05 mg/kg 250 02182 Total Xylenes 1330-20-7 2.2 0.2 mg/kg 250 The analysis for volatiles was performed on a sample which was preserved in methanol. The reporting limits were adjusted appropriately. This sample was submitted to the lab after the method holding time had already expired. Poor surrogate recoveries were observed for this sample due to the dilution needed to perform the analysis. Due to excessive foaming of the sample, normal reporting limits were not attained. 02858 Selected SVOA's in soil by SIM 02863 Naphthalene 91-20-3 . 0.38 0.010 mg/kg 10 02867 Acenaphthylene 208-96-8 N.D. 0.003 mg/kg 10 02868 Acenaphthene 83-32-9 0.087 0.003 mg/kg 10 02870 Fluorene 86-73-7 0.36 0.003 mg/kg 10 02871 Phenanthrene 85-01-8 0.77 0.003 mg/kg 10 02872 Anthracene 120-12-7 0.083 0.003 mg/kg 10 f .
