Data was accepted based on the LCS or CCV recovery. <br /> t. <br /> Definitions <br /> Blank Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples. <br /> LCS Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte <br /> recovery. <br /> MS/MSD Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication o <br /> how that sample matrix affects analyte recovery. <br /> LCCB Continuing Calibration Blank - Analyzed m verify the instrument baseline is within criteria. <br /> L CCV Continuing Calibration Verification - Analyzed m verify the instrument calibration is within criteria. <br /> ND Non-detect - Result was below the DQO listed for the analyte. <br /> DQO Dara Quality Objective - This is the criteria against which the quality control data is compared. <br /> L <br /> i <br /> L <br /> t_ <br /> m------1n-. <br /> — Corporate Offices S Laboratory Office&Laboratory Field Office <br /> P.O.Box 272/853 Corporation Street 2500 Stagecoach Road Visalia,California <br /> Santa Paula,CA 93061-0272 Stockton,CA 95215 TEL (559)734-9473 <br /> TE1-: (805)392-2000 TEL: (209)942-0181 FAX: (559)734-8435 <br /> - FAX: (805)525-4172 FAX: (209)942-0423 Mobile: (559)737-2399 <br /> CA NELAP Certification No.0111OCA CA ELAP Certification No.1563 <br /> CA ELAP Certification No. 1573 <br />
