Refer to the"SWRCB LUFT Field Manual",Appendix D(B),Table 3-5 on page A20 for <br /> mininumr detection limits for motor vehicle fuel(gasoline and diesel). Refer to"Th-Regional Board Staff Recommendations for <br /> Initial Evaluation and Investigation of UST's"for the waste and motor ail minimum.detection limits. <br /> Detection Limits that rem on below the MCL,STLC or Allowable Limit of the contaminant in question will be accepted, <br /> however laboratory shall utilize the most conservative method. <br /> LABORATORY ANALYSES TERMINOLOGY: <br /> TPH-G Total Petroleum Hydrocarbon,Gasoline,GC/FID(5030)8015 mod or GC/MS 8260 <br /> TPH-D Total Petroleum Hydrocarbon,Diesel,GC/FW(3550),9015 nod or GCIMS 8260 <br /> BTX&E Benzene,Toluene,Xylenc&Ethyl Benzene,GC/PID$020 or GCIMS 8260 <br /> CL HC Chlorinated Hydrocarbon,GCIHSD 8010,GOMS 8240 or 9260 <br /> TOTAL LEAD Total lead,AA 7420, AA 7421 or ICP-AES 6010 <br /> OXYGENATES MTBE,ETaE,TAME,DIPE,&TBA GC/M5 8260(For MTBE,screen only you may use 8020) <br /> METALS ICAP or AA Inductively Coupled Plasma Atomic Emission Spectrometry 6010 or Atomic Absorption Spectrometry 7000. <br /> Metals:Cadmlunt,Chromium III and Vl,Lead,Zltec and Nickel. <br /> PCB Polychlorinatod Biphenyls,GC/MS$270 or 8080 <br /> GC-FID Gas Chromatography,Flame Ionization Detection <br /> Method 3050 Acid digestion <br /> Method 3540 Soxhlct sample preparation <br /> Method 3550 Sonication sample preparation,extraction method <br /> Mcthod 5030 Purge and trap sample preparation <br /> QAIQC Qaality Amirance/Quarity Conuol <br /> Nortel: To avoid false positive detection of benzene,benzene-free solvents are to be used. Fusedcapillarycolumns are preferred to packed <br /> columns;a packed column may be used as a"first cut'with"dirty"samples or once the hydrocarbons have been characterized and proper QAIQC <br /> is followed. <br /> For drinking water sources,EPA recommends that the$00 series for volatile organic should be used in preference to the 600 series because the <br /> detcetion limits are lower and the QAlQCis better. Samples exhibiting any levelofbcavy metal contamination may require further analysis.EHD <br /> recommends holding those samples until disposal is indicated. <br /> EH 23 046 (Revised 3/15102) page 8 <br />
