N.D. 1.0 mg/kg 25 <br /> The analysis for volatiles was performed on a sample which was preserved <br /> in methanol. 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 /> 07584 PPL + Xylene (total) by 8260 <br /> 02016 Methyl Tertiary Butyl Ether 1634-04-4 N.D. 0.001 mg/kg 1.01 <br /> 02017 di-Isopropyl ether 108-20-3 N.D. 0.001 mg/kg 1.01 <br /> 02018 Ethyl t-butyl ether 637-92-3 N.D. 0.001 mg/kg 1.01 <br /> 02019 t-Amyl methyl ether 994-05-8 N.D. 0.001 mg/kg 1.01 <br /> 02020 t-Butyl alcohol 75-65-0 N.D. 0.020 mg/kg 1.01 <br /> 05460 Benzene 71-43-2 N.D. 0.001 mg/kg 1.01 <br /> 05466 Toluene 108-88-3 N.D. 0.001 mg/kg 1.01 <br /> 05474 Ethylbenzene 100-41-4 N.D. 0.001 mg/kg 1.01 <br /> 06301 Xylene (Total) 1330-20-7 N.D. 0.001 mg/kg 1.01 <br /> Poor surrogate recoveries were observed for the GC/MS volatile fraction. <br /> The analysis was repeated and poor surrogate recoveries were again observed <br /> indicating a significant matrix effect. <br /> The GC/MS volatile internal standard peak areas were outside the QC limits <br /> for both the initial analysis and the re-analysis. The values reported here <br /> are from the initial analysis of the sample. <br /> State of California Lab Certification No. 2116 <br /> Laboratory Chronicle <br /> CAT Analysis Dilution <br /> Analysis Name Method Trial# Date and Time Analyst Factor <br /> • <br /> Lancaster Laboratories,Inc. <br /> M EMB E R 2425 New Holland Pike <br /> PO Box 12425 <br /> Lanca® 717-656-23PA 00 Fax: <br /> 2425 <br /> 717-656-2300 Fa x:717-656-2681 2216 Rev.10/2/07. <br />
