The following information is <br />pertinent to the interpretation of this data package. <br />After a thorough review of the raw data for job 930997, it was <br />noticed that the WAD-CN result for samples RCG-3U and RCG-4U exceeded <br />the T-CN result. Except for T-CN on sample RCG-3U, the samples were <br />reanalyzed for WAD-CN and T-CN and reported under Core ID 930997 (11- <br />12). Sample RCG-3U was originally analyzed and duplicated for T-CN <br />on June 6, 1993. The duplicate value is reported as the reanalysis <br />value under Core ID 930997-11. All reanalysis was performed past the <br />EPA recommended holding time of 14 days. <br />In an effort to more effectively perform reanalysis for T-CN and WAD- <br />CN within the EPA recommended holding of 14 days, quality control for <br />reanalysis will consist of a laboratory control sample and <br />calibration verification. <br />Patr ck J.
