Those methods not found in <br />SW 846 are specifically noted below. Refer to the "SWRCB LUFT Field Manual% Appendix D (B), Table 3-5 on page A20 <br />for minimum detection limits for motor vehicle fuel (gasoline and diesel). Refer to 1-2-3 "Regional Board Staff <br />Recommendations for 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/MS 8260 <br />CL HC <br />Chlorinated Hydrocarbon, GC/HSD 8010, GC/MS 8240 <br />TOTAL LEAD <br />Total lead, AA 7420, AA 7421 or ICP -AES 6010 <br />MTBE <br />Methyl Tertiary Butyl Ether, GC/PID 8020 and confirmed by GC/MS 8260 <br />METALS ICAP or AA <br />Inductively Coupled Plasma Atomic Emission Spectrometry 6010 or Atomic Absorption <br />Spectrometry 7000.

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 have <br />been characterized and proper 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 <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 those samples until disposal is indicated. <br />EH 23 046 (Revised 10/24/97) Page 8 <br />
