Samples which were non detect for this analyte were accepted. <br /> Definitions <br /> MS/MSD : Matrix Spikes-A random sample is spiked with a known amount of analyte. The recoveries are an indication of <br /> how that sample matrix affects analyte recovery. <br /> ICH :Initial Calibration Blank-Analyzed to verify the instrument baseline is within criteria. <br /> ICV :Initial Calibration Verification-Analyzed to verify the instrument calibration is within criteria. <br /> CCB :Continuing Calibration Blank-Analyzed to verify the instrument baseline is within criteria. <br /> CCV :Continuing Calibration Verification-Analyzed in verify the instrument calibration is within criteria. <br /> ND :Non-detect-Result was below the DQO listed for the analyte. <br /> DQO :Data Quality Objective-This is the criteria against which the quality control data is compared. <br /> Report continued on next page... <br /> CTTJCQ3^9'j. ou�litConVel Raga I <br /> Corporate Offices&Laboratory Office&Laboratory Field Office <br /> P.O.Box 272/853 Corporation Street 2500 Stagecoach Road Visalia,Cafrfomia <br /> Santa Paula,CA 93061-0272 Stockton,CA 95215 TEL (559)73x-9473 <br /> TEL: (805)392-2000 TEL (209)942-0162 FAX: (559)7348435 <br /> FAX: (805)525-4172 FAX: (209)942-0423 Mobile: (559)737-2399 <br /> CA NELAP Certification No.01110CA CA ELAP Cert cation No. 1563 <br /> CA ELAP Certification No.1573 <br />
