It is prepared to verify that the preparation process is not <br />BS <br />affecting analyte recovery. <br />: Blank Spike Duplicate of MMSD pair- A blank duplicate is spiked with a known amount of analyte. It is prepared to verify that <br />BSD <br />Cho preparation process is not affecting analyte recovery. <br />: BSMSD Relative Percent Difference (RPD) - The BS relative percent difference is an indication of precision for the preparation <br />BSRPD <br />and analysis. <br />ND <br />: Non -detect - Result was below the DQO listed for the analyte. <br />DQO <br />: Data Quality Objective - This is the criteria against which the quality control data is compared. <br />!Page 6 of 6 <br />
