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 Iaboratory 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, GCIFID (3550), 8015 mod or GCIMS 8260 <br />BTX v& E Benzene, Toluene, Xylene & Ethyl Benzene, GC/PIID 8020 or GCIMS 8260 <br />CL HC Chlorinated Hydrocarbon, GCIHSD 8010, GCIMS 8240 <br />TOTAL LEAD Total lead, AA 7420, AAA 7421 or ICP -AES 6010 <br />MTBE Methyl Tertiary Buryl Ether, GC/MS 8260 <br />METALS ICRP or AA Inductively Coupled.

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 10/24197) Page 8 <br />
