Eizvh'01117'1e171a1 Network , <br /> PAGE 10 <br /> AEN (CALIFORNIA) <br /> QUALITY CONTROL REPORT <br /> JOB NUMBER: 9503493 <br /> I <br /> CLIENT PROJECT ID: USA #65 <br /> Ouali6 Control and Project Summary <br /> All laboratory quality control parameters were found to be within established <br /> limits. <br /> f <br /> Definitions ' <br /> Laboratory Control Sample (LCS)/Method Spike(s): Control samples of known composition. LCS and Method Spike <br /> data are used to validate batch analytical results. <br /> Matrix Spike(s): Aliquot of a sample (aqueous or solid) with added quantities of specific compounds and <br /> subjected`,to the entire analytical procedure. Matrix spike and matrix spike duplicate OC data are advisory. <br /> Method Blank: An analytical control consisting of all reagents, internal standards, and surrogate standards <br /> carried through the entire analytical process. Used to monitor laboratory background and reagent contamination. <br /> Not Detected (ND): Not detected at or above the reporting limit. <br /> Relative Percent Difference (RPD): An indication of method precision based on duplicate analysis. <br /> Reporting :Limit (RL): The lowest concentration routinely determined during laboratory operations. The RL is <br /> generally".1 to 10 times the Method Detection Limit (MDL). Reporting limits are matrix, method, and analyte <br /> dependent and take into account an dilutions performed as art of the analysis. <br /> Pe s. <br /> Y <br /> Ae P Y <br /> Surrogates: Organic compounds which are similar to analytes of interest in chemical behavior, but are not found <br /> in environmental samples. Surrogates are added to all blanks, calibration and check standards samples, and <br /> spiked samples. surrogate recovery is monitored as an indication of acceptable sample preparation and <br /> instrumental performance. <br /> i <br /> D: Surrogates diluted out. <br /> #: indicates result outside of established laboratory QC limits. <br /> F <br />
