December 9,1992 <br /> Sample Log 5445 <br /> ' To: Bob Marty <br /> Geological Audit Service <br /> Re: Possible labelling mixup <br /> Sample MW-1/11-24-92. Gas/BTEX was analyzed from duplicate <br /> containers, both of which showed contamination. MW-3/11-24 <br /> was uncontaminated. This trend was reversed on the <br /> extractable TPH analysis, leading me to believe that the <br /> labels were switched at some point in the extraction process. <br /> ' No duplicate Iliters were submitted, therefore we could not <br /> re-extract to clarify the situation. <br /> If re-sampling is necessary, WEST will perform the analysis <br /> free of charge on an expedited basis. <br /> Please contact me if any further clarification is necessary. <br /> Stewart Podolsk <br /> Senior Chemist <br /> I ' <br /> i <br /> I <br /> . , <br /> Western Environmental Science & Technology 45133 County Road 32B Davis, CA 95616 - 916 753-9500 FAX: 916 757-4852 i <br />
