You asked us to look into the original analyses for Well N-7 <br /> and its duplicate. An audit of the DRO,GRO and VOC analyses found no laboratory errors. Two additional vials were reanalyzed for <br /> DRO and the results were consistent with the original analysis of N-7 duplicate,but not N-7.The DRO reanalysis of N-7 has been reported <br /> in the reissue. The GRO and VOC analyses were originally screen analyzed and these results were consistent with the final analysis of N-7 <br /> duplicate,but not N-7. The screen analysis has been reported in the reissue. <br /> As we discussed,the 6 VOA vials we received for these analyses all had variable amounts of fine black sediment and suspended material, <br /> and they all had very strong non-hydrocarbon odors. Given the apparent variability between the different sample containers of the same <br /> location,the most consistent analytical results have been reported. <br /> If we can be of further assistance,please let us know. <br /> Roger Scholl,Ph.D. <br /> Laboratory Director <br /> Rogerh.D.,Laboratory Director• •Randy Gardner,Laboratory Manager• •Walter Hinchman,Quality Assurance Officer <br /> lowSacramento,CA•(916)366-9089/Las Vegas,NV•(702)281-4848 /Carson,CA-(714)386-2901/info@alpha-anallytical.com <br /> Alpha Analytical,Inc.certifies that the test results meet all requirements of NELAC unless footnoted otherwise <br /> U . 1 Of 1 <br /> DO EV Statement of Data Authenticity Alnha Analvtiral Inn. at—t,that tha data rwv 1 hac not heen altered an anv <br />
