<br />All analyses methods are designated EPA methods described in EPA SW 846, Third Edition. 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 USTs" 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 />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 GCIMS 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 />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 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.
