Those methods not found in SW 846 are <br /> specifically noted below. Refer to the "SWRCB LUFT Field Manual",Appendix D (B),Table 3-5 on page A20 for minimum 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 MCL,STLC or <br /> Allowable Limit of the contaminant in question will be accepted,however laboratory 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,GC/FID(3550),8015 mod or GC/MS 8260 <br /> BTX&EBenzene,Toluene,Xylene&Ethyl Benzene,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,DIPE,&TBA GC/MS 8260(For MTBE screen only you may use 8020) <br /> METALS ICAP or AA Inductively Coupled Plasma Atomic Emission Spectrometry 6010 or Atomic Absorption Spectrometry 7000.

Fused capillary columns are preferred to packed 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 followed. For <br /> drinking water sources,EPA recommends that the 500 series for volatile organic should be used in preference to the 600 series because the detection <br /> limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require further analysis.PHS-EHD <br /> recommends holding those samples until disposal is indicated. <br /> EH 23 046 (Revised 05/09/00) <br /> 5 <br />
