QC Data DQO NoteMethodConstituentDate/ID Type <br />Wet Chem <br />Nitrite as Nitrogen <br />DQO <br />LCS <br />MS <br />: Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples. <br />: Data Quality Objective - This is the criteria against which the quality control data is compared. <br />: Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte recovery. <br />: Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample matrix <br />affects analyte recovery. <br />: Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyted. The recoveries are an <br />indication of how that sample matrix affects analyte recovery. <br />: MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation and <br />analysis. <br />: Non-detect - Result was below the DQO listed for the analyte. <br />mg/L <br />mg/L <br />mg/L <br />mg/L <br />mg/L <br />1.218 <br />0.6090 <br />0.6090 <br />ND <br />102% <br />100% <br />100% <br />0.4% <br />Corporate Offices & Laboratory <br />853 Corporation Street <br />Santa Paula, CA 93060 <br />TEL: (805)392-2000 <br />CA ELAP Certification No. 1573 <br />Office & Laboratory <br />563 E.
