.all analvses methods are designated EPA methods described in EPA SW 3�t6, Third. Edition. Those methods not found in SW 346, are specifically noted below. Refer to the 'SWRCB L=Field Manual", Appendix A-20, Table 3-5 for detection limits of motor vehicie fuels (gasoline and diesel). Refer to 1-2-3 "Re¢ionai Board Staff Recommendations for Initial Evaluation and Investigation of UST's" for the waste and motor oil detection limits. Detection Limits that remain below the MCL, MC or Allowable Limit of the contaminant in question will he accepted, however laboratory shall utilize the most conservative method.

Fused capillary columns are acked column. may be used as a "first cut" with "dire+" samples or once the hydrocarbons preferred to packed columns; a p I ave been characterized and proper QA/AC is followed. For Drinking water sources, EPA recommends that the 500 series for volatile organics 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 these samples until disposal is indicated. EH 23 043 (Revised 7/10/92) Page 3
