Fused capillary colurmu are preferred to packed columns;a <br /> packed column may be used as a'first cut"with"dirty"samyles or once the hydrocarbons have been characterized aid 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 670 series because the detection limits <br /> are lower and the QA/QC is tetter. Samples exhibiting any hovel of heavy metal contanunation may require further analysis.PHSEHD recommends <br /> holding those samples until disposal is indicated. <br /> EH 23 046 (Revised 05/09/00) <br /> S,-11 JOAQUIN COUNTY <br /> ENVIRONMENTAL HEALTH DEPARTMENT <br /> (209)468.3420 <br /> AUTHORIZATION TO RELEASE <br /> ANALYTICAL RESULTS <br /> •GEOTECHNICAL DATA <br /> ' ENVIRONMIINTALSITE ASSESSMENT INFORMATION <br /> 1 <br /> I,THE UNDERSIGNED OWNER AND/OR OPERATOR OF THE PROPERTY AND/OR FACILITY <br /> LOCATED AT k—1 //�— <br /> (Street Address) (City) <br /> HEREBY AUTHOR12 E " <br /> t7;uboratory) <br /> TO RELEASE ANY AND AIL ANALYTICAL INFORMATION TO SAN JOAQUIN COUNTY ENVIROT Rv ENTAL HEALTH <br /> DEPARTMENT AS SOON AS IT IS AVAILABLE AND AT THE SAME <br /> 6 <br />
