i • <br />;~GB~~ <br />June 25, 1996 <br />CORE LABORATORIES <br />SAMPLE DELIVERY GROUP NARRATIVE <br />Customer: Greystone <br />Project: 484-03 <br />Core Laboratories Project Number: 961500 <br />Method 624 GC/MS Volatiles Analysis: <br />The second source check standard associated with this project was outside the upper <br />acceptance limit for trichloroethene. However, trichloroethene was within acceptance limits <br />in the reference standard associated with this project. Since there was no detections for <br />trichloroethene in any of the associated samples, the samples were not reanalyzed. <br />The pesticide calibration associated with this project had several compounds greater than <br />ten percent relative standard deviation on the confirmation column. The PCB calibration <br />had all compounds greater than ten percent relative standard deviation. However since there <br />were no detections for any pesticides or PCBs in any of the associated samples, the samples <br />were not reanalyzed. <br />~~~ <br />Linda L.
