<br />MINIMUM VERIFICATION LABORATORY ANALYSIS
<br />All analysis methods are the designated EPA methods described in EPA SW 846, i=d Edition. loose mcrnoas not iouau wow oyo ace
<br />specifically noted below. Refer to the "SWRCB LLTFT Field Manual", Appendix D (B), Table 3-5 on page A20 for minimum detection
<br />limits for motor vehicle fuel (gasoline and diesel). Refer to "Tri -Regional Board Staff Recommendations for Initial Evaluation and
<br />Investigation of UST's" for the waste and motor oil minimum detection limits. Detection Limits that remain below the MCL, STLC or
<br />Allowable Limit of the contaminant in question will be accepted, 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 />TPK-D Total Petroleum Hydrocarbon, Diesel, GC/FID (3550), 8015 mod or GC/MS 8260
<br />BTX & EBenzene, Toluene, Xylcne & 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, RIPE, & TBA GC/MS 8260 (For MTBE screen only you tray use 8020)
<br />METALS ICAP or AA Inductively Coupled Plasma Atomic Emission Spectrometry 6010 or Atomic Absorption Spectrometry 7000, Metals:
<br />Cadmium, Chromium III and VI, Lead, Zinc and Nickel.
<br />PCB Polychlorinated Biphenyls, GC/MS 8270 or 8080
<br />GC -FID Gas Chromatography, Flamc 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 columns; a
<br />packed column may be used as a "first cut" with "dirry" samples or once the hydrocarbons have been characterized and proper QA/QC is followed. For
<br />drinking water sources, EPA recommends that the 500 series for volatile organic should be used in preference to the 600 series because the detection
<br />limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require further analysis. PHS-EHD
<br />recommends holding those samples until disposal is indicated.
