Those methods nix found in SW <br /> 846 are specifically noted below. Refer to the"SWRCB LOFT Field Manual". Appendix D(B). Table 3-5 on page AM for <br /> minimum detection limits for motor vehicle fuel(gasoline and diesel). Refer to "Tri-Regional Board Staff Recommendations for <br /> 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 utilise the most conservative method. <br /> LABORATORY ANALYSES TERMINOLOGY: <br /> TPH-G Total Petroleum Hydrocarbon,Gasolim.GC/FID(5030)8015 mod or GC/MS 8260 <br /> TPH-D Total Petroleum Hydrocarbon,Diesel.GC/FID(3550),8015 nod or GC/MS 8260 <br /> BTX&E Benzene.Toluene,Xylem do Ethyl Benzene,GC/PlD 8020 or GGMS 8260 <br /> CL HC Chlorinated Hydrocarbon,GC/HSD 8010.GC/MS 8240 or 8260 <br /> TOTAL LEAD Total Lead.AA 7420.

Fuad capillary cotumeu are pm&c red to packed <br /> columns:a packed column may be used as a"First cut"with'ditty'samples or once the hydrocarbons have been characterized and proper <br /> QA/QC is followed. <br /> For drinking water sources, EPA recommends that the 300 series for volatile organic amid be used in preference to the 600 series because the <br /> detection limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require Rusher analysis. <br /> PHS-EM recommends holding those samples urxil disposal is indicated. <br /> EH Z3 046 (Revised 05/091(30) Page 8 <br /> 1 <br /> 10/25/01 THU 10:14 [TX/RX NO 87481 IM011 <br />
