Those methods not found m SW 846 are specifically noted below. Refer to the 'SWRCB LUFT Field Manual", Appendix D (B), Table 3-1 on page A20 I For minirnnm detection limits for motor vehicle fuel (gasoline and diesel). Refer to 1-2-3 'Regional Board Staff Recommendations for Initial Evaluation and Investigation of UST's' for the waste and motor oil minimum detection limits. Detection Limits that remain below the MCL, STLC or Allowable Limit of the contaminant In question will be accepted, however laboratory shall utilize the most conservative method.

Fused capillary columns aro preferred to packed columns: a packed column may be used as a 'first cut" with 'ditty'samples or once the hydSoearbons have been characterized and proper QA/QC is followed. Por drinking water sources, EPA recommends that the 500 series for volatile organic should be used In preference to the 600 series because the detection limits are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require further analysis. PHS-EHD recommends holding those samples until disposal Is Indicated. FIT 23 046 (Revised 10/24/97) Page 8
