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 /> Poor surrogate recoveries were observed for this sample due to the dilution <br /> needed to perform the analysis. <br /> 05547 TPH - DRO CA LUFT (Soils) n.a. 15. 10. mg/kg 1 <br /> 02516 TPH Fuels by GC (Soils) <br /> 02518 Total TPH n.a. 25. 10. mg/kg 1 <br /> 02525 TPH Jet Fuel C9-C19 n.a. 25. 4.0 mg/kg 1 <br /> 02552 TPH Motor Oil C16-C36 n.a. N.D. 10. mg/kg 1 <br /> TPH quantitation is based on peak area comparison of the sample pattern to <br /> that of a hydrocarbon component mix calibration in a range that includes <br /> C8 (n-octane) through C40 (n-tetracontane) normal hydrocarbons. <br /> The sample fingerprint is more similar to gasoline than jet fuel. <br /> 07360 BTEX+MTBE by 8260B <br /> 02016 Methyl Tertiary Butyl Ether 1634-04-4 N.D. 0.062 mg/kg 124.69 <br /> 05460 Benzene 71-43-2 N.D. 0.062 mg/kg 124.69 <br /> 05466 Toluene 108-88-3 N.D. 0.12 mg/kg 124.69 <br /> 05474 Ethylbenzene 100-41-4 0.18 0.12 mg/kg 124.69 <br /> 06301 Xylene (Total) 1330-20-7 0.24 0.12 mg/kg 124.69 <br /> The GC/MS volatile analysis was performed according to the medium level <br /> soil method due to the level of non-target compounds. Therefore, the <br /> reporting limits were raised. <br /> State of California Lab Certification No. 2116 <br /> Laboratory Chronicle <br /> CAT Analysis Dilution <br /> No. Analysis Name Method Trial# Date and Time Analyst Factor <br /> 01725 TPH-GRO - Soils N.
