Miscellaneous Information <br />Electronic Package Comment <br />m <br />ENVIRONMENTAL H AL.t i -i <br />DEPARTMENT <br />The following package was generated using an electronic data processing program referred to as "virtual <br />packaging". In an effort to increase quality and efficiency, the laboratory is developing systems to eventually <br />generate all data packages electronically. The following change from "traditional" packages should be noted: <br />Analyst/peer reviewer initials and dates are not present on the electronic data files. Presently, all initials and <br />dates are present on the original raw data. These hard copies are temporarily stored in the laboratory. The data <br />validator will always sign and date the case narrative. Data that are not generated electronically, such as hand <br />written pages, will be scanned and inserted into the electronic package. <br />Data Exception (DER) Documentation <br />Data exception report (DER) is generated to document procedural anomalies that may deviate from referenced <br />SOP or contractual documents. A DER was not required for the samples in this SDG in this batch. <br />Manual Integrations <br />Certain standards and samples may have required manual integration to correctly position the baseline as set in <br />the calibration standard injections. <br />Additional Comments <br />The higher results from either column have been chosen and reported in the data package for the client samples, <br />MB and LCS. The data reported for the MS and MSD are from the same analytical column as the parent sample. <br />System Configuration <br />The Semi -Volatiles -PCB analysis was perfonned on the following instrument configuration: <br />Instrument <br />Instrument <br />System <br />Column ID <br />Column <br />ID <br />Configuration <br />Description <br />Agilent 7890A Gas <br />30m x <br />ECD9A.I_1 <br />Chromatograph/Dual ECD w/ <br />7890A GC/ECD <br />Restek <br />0.251nm, <br />7693 Autosampler <br />Rtx-CLPest I <br />0.25um <br />Agilent 7890A Gas <br />30m x <br />ECD9A.I_2 <br />Chromatograph/Dual ECD w/ <br />7890A GC/ECD <br />Restek <br />0.25mm, <br />7693 Autosampler <br />Rtx-CLPest 2 <br />0.20um <br />Certification Statement <br />Where the analytical method has been perfonned tinder NELAP certification, the analysis has met all of the <br />requirements of the NELAC standard unless otherwise noted in the analytical case narrative. <br />Page 9 of 17 <br />
