Those methods nor found in SW 846 are specifically noted below. Refer to the "SWRCB LUFT Field Manual", Au pendtz D (B), Table 3-5 on page A20 for minimum detection limitstor motor vehicle fuel (gasoline and diesel). Refer to 1-1--3 "Regional Board Staff Recommendations for Initial Evaluation and Investigation of UST's' for the waste and motor oil minimum detection limits. Detection Limits that remain below the MCL, STLC or Allowable Limit of the contaminant in question will be accepted, however laboratory shall utilize the most conservative method. LABORATORY ANALYSES TERMINOLOGY: TPH-G Total Petroleum Hydrocarbon, Gasoline, GC/FID (5030) 8015 mad or GUMS 8260 TPH-D Total Petroleum Hydrocarbon, Diesel, GC/FID (3550), 8015 mod or GC/MS 8260 BTX & E Benzene, Toluene, Xylene & Ethyl Benzene, GC/PID 8020 or GC/MS 8260 CL HC Chlorinated Hydrocarbon, GC/HSD 8010, GC/MS 8240 TOTAL LEAD Total lead, AA 7420, AA 7421 or ICP-AES 6010 MTBE Methyl Ternary Buryl Ether, GC/PID 8020 and confirmed by GC/MS 8260 METALS IC.AP or AA Inductively Coupled Plasma Atomic Emission Spectrometry 6010 or Atomic Absorption Spectrometry 7000.

Fused capillary columns are preferred to packed columns; a packed column may be used as a "fust cut" with "dirty" samples or once the hydrocarbons have been characte::zed and proper QA/QC is followed. For drinking water sources, EPA recommends that the 500 series for volatile organic should be used in preference to the 600 series because the detection Limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require further analysis. PHS-EHD recommends holding those samples until disposal is indicated. EH 7-3 046 (Revised 7/10/96) Page 8
