Those methods not found in SW <br /> 846 are specifically noted below. Refer to thq"SWRCB LUFT Field Manual", Appendix D(B), Table 3-5 on page A20 for <br /> minimum detection limits for motor vehicle fuel(gasoline and diesel). Refer to "Tri-Regional Board Staff Recommendations for <br /> Initial Evaluation and Investigation of UST's" for the waste and motor oil minimum detection limits. <br /> Detection Limits that remain 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/FID(3550), 8015 mod or GUMS 8260 <br /> BTX&E Benzene,Toluene, Xylene&Ethyl Benzene, GC/PID 8020 or GC/MS 8260 <br /> CL HC Chlorinated Hydrocarbon, GC/HSD 8010, GC/MS 8240 or 8260 <br /> TOTAL LEAD Total lead,AA 7420, AA 7421 or ICP-AES 6010 <br /> OXYGENATES MTBE, ETBE,TAME, DIPE,&TBA GC/MS 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:Cadmium,Chromium HI and VI,Lead, Zinc and Nickel. <br /> PCB Polychlorinated Biphenyls, GC/MS 8270 or 8080 <br /> GC-FH) Gas Chromatography, Flame Ionization Detection <br /> Method 3050 Acid digestion <br /> Method 3540 Soxhlet sample preparation <br /> Method 3550 Sonication sample preparation,extraction method <br /> Method 5030 Purge and trap sample preparation <br /> QA/QC Quality Assurance/Quality Control <br /> Notes: To avoid false positive detection of benzene,benzene-free solvents are to be used. Fused capillary columns 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 <br /> QA/QC is followed. <br /> For drinking water sources, EPA recommends that the 500 series for volatile organic should be used in preference to the 600 series because the <br /> detection limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require further analysis. <br /> PHS-EHD recommends holding those samples until disposal is indicated. <br /> EH 23 046 (Revised 05/09/00) Page 8 <br />
