CProject Narrative <br /> (D1J010146) <br /> On September 29, 2001, the STL Denver laboratory received seven samples from <br /> Condor Earth Technology. This report presents the analytical results as well as <br /> supporting information to aid in the evaluation and interpretation of the data. The <br /> samples were received at a temperature of 3.8°C in good condition. The laboratory <br /> composited several samples prior to analysis. <br /> With the exception of the below mentioned anomalies, standard analytical protocols <br /> were followed in the analysis of the samples. All laboratory QC samples analyzed in <br /> conjunction with the samples in this project were within established control limits. <br /> The test results shown in this report meet all requirements of NELAC, and any <br /> exceptions are noted below. This report shall not be reproduced, except in full, without <br /> written permission from the laboratory. <br /> This report includes reporting limits (RLs) less than STL Denver's standard reporting <br /> limit. The reported sample results and associated reporting limits are being used <br /> specifically to meet the needs of this project. Note that data are not normally reported <br /> to these levels without qualification because they are inherently less reliable and <br /> / potentially less defensible than required by the latest industry standards. <br /> l Pesticides, SW846 8081A <br /> In the analysis of samples DlJ010146-001 for4,4'-DDE, DlJ010146-002 for endrin and <br /> endrin aldehyde, D1J010146-003 for endrin, DlJ010146-004 for 4,4'-DDE, and <br /> DlJ010146-005 for 4,4'-DDE and 4,4'-DDT there was a difference greater than 40% <br /> between the primary and confirmation column results. The lower results are reported <br /> and the associated sample data are flagged "COL". <br /> A continuing calibration verification (CCV) associated with samples DlJ010146-001 <br /> and 002 demonstrated percent differences greater than 15% for b-BHC, 4,4'-DDD, <br /> kepone, endrin aldehyde, 4,4'-DDT, and methoxychlor. The average percent difference <br /> of all compounds in the CCV was less than 15%; therefore the CCV met all criteria for <br /> the method. <br /> A continuing calibration verification (CCV) associated with samples D1J010146-003, <br /> 004, and 005 demonstrated percent differences greater than 15% for b-BHC, 4,4'-DDD, <br /> kepone, endrin aldehyde, 4,4'-DDT, and methoxychlor.
