Those methods not found in SW <br />846 are specifically noted below. Refer to the "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 <br />Total Petroleum Hydrocarbon, Gasoline, GC/FID (5030) 8015 mod or GC/MS 8260 <br />TPH-D <br />Total Petroleum Hydrocarbon, Diesel, GC/FID (3550), 8015 mod or GC/MS 8260 <br />BTX & E <br />Benzene, Toluene, Xylene & Ethyl Benzene, GC/PID 8020 or GC/M[S 8260 <br />CL HC <br />Chlorinated Hydrocarbon, GC/HSD 8010, GC/MS 8240 or 8260 <br />TOTAL LEAD <br />Total lead, AA 7420, AA 7421 or ICP -AES 6010 <br />OXYGENATES <br />MTBE, ETBE, TAME, DIPS, & TBA GC/MS 8260 (For MTBE screen only you may use 8020) <br />METALS ICAP or AA <br />Inductively Coupled Plasma Atomic Emission Spectrometry 6010 or Atomic Absorption Spectrometry 7000. <br />Metals: Cadmium, Chromium III and VI, Lead, Zinc and Nickel. <br />PCB <br />Polychlorinated Biphenyls, GC/MS 8270 or 8080 <br />GC -FID <br />Gas Chromatography, Flame Ionization Detection <br />Method 3050 <br />Acid digestion <br />Method 3540 <br />Soxhlet sample preparation <br />Method 3550 <br />Sonication sample preparation, extraction method <br />Method 5030 <br />Purge and trap sample preparation <br />QA/QC <br />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 QA/QC <br />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. EHD <br />recommends holding those samples until disposal is indicated. <br />EH 23 046 (Revised 10/16/03) Page 8 <br />
