Those methods not found <br />in SW 846, 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 MCI., 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 GC1MS 8260 <br />TPH-D Total Petroleum Hydrocarbon, Diesel, GC/FID (3550), 8015 mod or 260 <br />8 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 />ICA? 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 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 -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 23 048 (Revised 7/10/92) Page 8 <br />
