Fused capillary columns are preferred to packed columns;a <br /> packed column may be used as a"first cut'with"dirty"samples or once the hydrocarbons have been characterized and proper QA/QC is followed. For <br /> 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 <br /> are lower and the QA/QC is better. Samples exhibiting any level of heavy metal contamination may require further analysis.PHS-EHD recommends <br /> holding those samples until disposal is indicated. <br /> EH 23 046 (Revised 05/09/00) <br /> SAN JOAQUIN COUNTY <br /> ENVIRONMENTAL HEALTH DEPARTMENT <br /> (209)468-3420 <br /> AUTHORIZATION TO RELEASE <br /> •ANALYTICAL RESULTS <br /> •GEOTECHNICAL DATA <br /> ' ENVIRONMENTAUSITE ASSESSMENT INFORMATION <br /> I,THE UNDERSIGNED OWNER AND/OR OPERATOR OF THE PROPERTY AND/OR FACILITY <br /> LOCATED AT <br /> (Street Address) (City) <br /> HEREBY AUTHORIZE <br /> (Laboratory) <br /> TO RELEASE ANY AND ALL ANALYTICAL INFORMATION TO SAN JOAQUIN COUNTY ENVIRONMENTAL HEALTH <br /> DEPARTMENT AS SOON AS IT IS AVAILABLE AND AT THE SAME <br /> 6 <br />
