Those methods not found to SW 846 are <br />specifically noted below. Refer to the "SWRCB LUFt Field Manual", Appendix D (13), Table 3-5 on page A20 for niin.►imum 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 NkICL, STLC or <br />Allowable Limit of the contaminant in question will be accepted, however laboratory shall utilize the most cotes ervatave 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, GC/FID (3550), 8015 mod or GC/MS 8260 <br />BTX & EBenzene, Toluene, Xylene & Ethyl Bcnzcne, 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.

Metals: <br />Notes: To avoid false positive detection of benzene, benzenofrce solvents are to be used. Fused capillary columns are preferred to packet columns; a <br />packed column may be used as a "first cut" with "dirty" samples or once the hydrocarbons have been characterized and proper QA/QC is f=ollowed. For <br />drinking water sources, EPA recommends that the 500 series for volatile organic should be used in preference to the 600 series bectause thee detection <br />limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require further analysis. PiIS-E _HD <br />recommends holding those samples until disposal is indicated. <br />EH 23 046 (Revised 05/09/00) <br />Page 5 <br />5 <br />JAN 25 '02 9:12 2094683433 PAGE.006 <br />
