The reporting limits were adjusted appropriately. <br /> The reported concentration of TPH-GRO does not include MTBE or other <br /> gasoline constituents eluting prior to the C6 (n-hexane) TPH-GRO range <br /> start time. <br /> A poor surrogate recovery was observed due to the dilution needed to <br /> perform the analysis. <br /> 02160 BTEX/MTBE <br /> 02174 Benzene 71-43-2 N.D. 0.1 mg/kg 500 <br /> 02177 Toluene 108-88-3 N.D. 0.1 mg/kg 500 <br /> 02178 Ethylbenzene 100-41-4 0.2 0.1 mg/kg 500 <br /> 02182 Total Xylenes 1330-20-7 2.9 0.3 mg/kg 500 <br /> 02199 MTBE 1634-04-4 N.D. 1.0 mg/kg 500 <br /> The analysis for volatiles was performed on a sample which was preserved <br /> in methanol. The reporting limits were adjusted appropriately. <br /> Due to dilution of the sample made necessary by the high level <br /> of non-target compounds, normal reporting limits were not <br /> attained. <br /> A poor surrogate recovery was observed due to the dilution needed to <br /> perform the analysis. <br /> 02729 Custom TPH with Ranges (soil) <br /> 02730 Total TPH n.a. 6,700. 400. mg/kg 100 <br /> 05011 C10-C36 n.a. 6,700. 400. mg/kg 100 <br /> Accurate surrogate recoveries could not be determined due to the dilution <br /> required for analysis of the sample. <br /> 02858 Selected SVOA's in soil by SIM <br /> 02863 Naphthalene 91-20-3 1.6 0.010 mg/kg 10 <br /> 02867 Acenaphthylene 208-96-8 N.D. 0.003 mg/kg 10 <br /> 02868 Acenaphthene 83-32-9 0.25 0.003 mg/kg 10 <br /> 02870 Fluorene 86-73-7 1.7 0.003 mg/kg 10 <br /> 02871 Phenanthrene 85-01-8 3.2 0.003 mg/kg 10 <br />
