MHA VERIFICATION LABORATORY ANALYSIS <br />W 846 are. specifically noted below. Refer to the "SWRCB LUFT Field Manual", Appendix D (B), Table 3-5 on page A20 for <br />inimum detection limits for motor vehicle fuel (gasoline and diesel). Refer to "Tri -Regional Board Staff Recommendations for <br />nitial 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 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 or 8260 <br />TOTAL LEAD Total lead, AA 7420, AA 7421 or ICP -AES 6010 <br />OXYGENATES MTBE, ETBE, TAME, DIPS, & 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 III and VI, Lead, Zinc and Nickel. <br />PCB Polychlorinated Biphenyls, GC/MS 8270 or 8080 <br />GC -FID 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 />itS-EHD recommends holding those samples until disposal is indicated. <br />23 046 (Revised 08/13/99) Page 8 <br />OXYGFNAM <br />NK <br />TANK <br />TPH-G <br />TPH-D <br />BTX & E <br />CL HC <br />TOTAL <br />MTBE <br />(MTBE. <br />METAts <br />PCB <br />CONTENTS <br />8015 <br />8015 <br />8020 <br />8010 <br />LEAD <br />8020 <br />TBA,DIPE, <br />ICRP/ <br />8270 <br />8260 <br />8260 <br />8260 <br />8240 <br />7420 <br />8260 <br />ETBE, <br />TAME) <br />AES <br />8080 <br />8260 <br />7421 <br />8260 <br />or <br />AA <br />LEADED GAS <br />X <br />X <br />X <br />X <br />UNL GAS <br />X <br />X <br />X <br />DIESEL <br />X <br />X <br />X <br />KEROSENE <br />X <br />X <br />X <br />UNK FUEL <br />X <br />X <br />X <br />X <br />X <br />PROD.
