Fused capillary <br />columns are preferred to packed columns; a packed column may be used as a "first cut' with "dirty" samples or <br />once the hydrocarbons have been characterized and proper QA/QC is followed. For drinking water sources, EPA <br />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 <br />may require further analysis. PHS-EHD recommends holding those samples until disposal is indicated. <br />EH23 046 (Revised 05/09/00) <br />EH 23 046 (revised 124/02) <br />c SjWAP\repsGx3ch23046.wpd Page 4 Wo #126686 <br />
