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 for <br /> minimum detection limits for motor vehicle fuel (gasoline and diesel). Refer io 1-2-3 "Regional Board Staff Recommendations <br /> 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 Total Petroleum Hydrocarbon, Gasoline.

Fused capillary columns are preferred to packed <br /> columns: a packed column may be used as a "first cut" with "dirty" samples or once the hydrocarbons have been characterized and proper <br /> 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 series because the <br /> detection limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require further analysis. <br /> PHS-EHD recommends holding those samples until disposal is indicated. <br /> EH 23 046 (Revised 10/19/98) Page 8 <br />
