The associated <br /> laboratory control standard (LCS)met acceptance criteria. <br /> No other analytical or quality issues were noted. <br /> GC/MS Semi VOA <br /> No analytical or quality issues were noted. <br /> GC Semi VOA <br /> No analytical or quality issues were noted. <br /> Metals <br /> Method 6010B:The matrix spike/matrix spike duplicate(MS/MSD)recoveries for batch 25451 were outside control limits. The <br /> associated laboratory control standard (LCS)met acceptance criteria. <br /> Method 6010B:The method blank for preparation batch 25451 contained a target compound above the reporting limit(RL). The <br /> associated sample(s)contained detects for this analyte(Potassium, K)at concentrations greater than 10X the value found in the method <br /> blank; therefore, re-extraction and/or re-analysis of samples was not performed. <br /> No other analytical or quality issues were noted. <br /> General Chemistry <br /> Method 353.2: The nitrate method blank was high on batch 21702. The method blank is taken from the same source as the ICB and <br /> CCB's,which were all below reporting limit. All affected samples have been reported. <br /> No other analytical or quality issues were noted. <br /> Organic Prep <br /> No analytical or quality issues were noted. <br /> Page 2 of 44 09/04/2007 <br />
