Those methods not found <br /> in SW 346, are specifically noted below. Refer to the 'SWRCB LUFT Field Manual", Appendix A-20, Table 3-5 for <br /> detection limits of motor vehicle fuels (gasoline and diesel). Refer to 1-2.3 'Regional Board Staff Recommendations for <br /> Initial Evaluation and Investigation of UST's" for the waste and motor oil detection limits. <br /> Detection Limits that remain below the ?ICL, 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 3260 <br /> TPH-D Total Petroleum Hydrocarbon, Diesel, GC/FID (3550), 3015 mod or GC/MS 8260 <br /> BTX & E Benzene, Toluene, Xylene & Ethyl Benzene, GC/PID 3020 or GC/MS 3260 <br /> CL HC Chlorinated Hydrocarbon, GC/HSD 3010, GC/MS 3240 <br /> TOTAL LEAD Total lead, AA 7420, AA 7421 or ICP-AES 6010 <br /> EDB Ethylene dibromide (DHS-AB 1803), GC/MS 3240 (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, Zinc and Nickel. <br /> PCB Polychlorinated Biphenyls, GC/MS 3270 or 3030 <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 <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 <br /> series because the detection limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal <br /> contamination may require further analysis. PHS-EHD recommends holding these samples until disposal is indicated. <br /> EH 23 043 (Revised 7/10/92) Page 3 <br />
