Those methods not found in <br /> SW 846,are specifically noted below. Refer to the "SWRCB LUFT Field Manual",Appendix A-20,Table 3-5 for detection <br /> limits of motor vehicle fuels (gasoline and diesel). Refer to 1-2-3 "Regional Board Staff Recommendations for Initial <br /> Evaluation and Investigation of UST's' for the waste and motor oil detection limits. <br /> Detection limits that remain below the MCI, STLC or Allowable Limit or 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 GC/MS 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 <br /> Total Lead Total lead, AA 7420, AA 7421 or ICP-AES 6010 <br /> EDB Ethylene dibromide (DHS-AB 1803), GC/MS 8240 (DHS-Luft) <br /> GC-FID Gas Chromatography, Flame Ionization Detection <br /> ICAP or AA Inductively Coupled Plasma Atomic Emission Spectrometry 6010 or Atomic Absorption <br /> Spectrometry 7000. Metals: Cadmium, Chromium III and VI, Lead, and Zinc. <br /> PCB Polychlorinated Biphenyls, GC/MS 8270 or 8080 <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-tree solvents are to be used. Fused capillary columns are <br /> preferred to packed columns; a packed column may be used as a "first cut" with "dirty" samples or once the hydrocarbons <br /> have been characterized and proper QA/AC is followed. <br /> For Drinking water sources,EPA recommends that the 500 series for volatile organics be used in preference to the 600 series <br /> because the detection limits are lower the QA/QC is better. <br /> EH 23 048 (Rev 11/7190) Page 8 <br />
