July 25, 2014 Lab ID : STK1436562 Forward Inc. Customer : 3-8692 Quality Control-Inorganic Definition CCV Continuing Calibration Verification-Analyzed to verify the instrument calibration is within criteria. CCB Continuing Calibration Blank-Analyzed to verify the instrument baseline is within criteria. Blank Method Blank-Prepared to verify that the preparation process is not contributing contamination to the samples. RgBlk Method Reagent Blank-Prepared to correct for any reagent contributions to sample result. LCS Laboratory Control Standard/Sample-Prepared to verify that the preparation process is not affecting analyte recovery. MS Matrix Spikes-A random sample is spiked with a known amount of analyte.The recoveries are an indication of how that sample matrix affects analyte recovery. MSD Matrix Spike Duplicate of MS/MSD pair-A random sample duplicate is spiked with a known amount of analyted.The recoveries are an indication of how that sample matrix affects analyte recovery. Dup Duplicate Sample-A random sample with each batch is prepared and analyzed in duplicate.The relative percent difference is an indication of precision for the preparation and analysis. MSRPD :MS/MSD Relative Percent Difference(RPD)-The MS relative percent difference is an indication of precision for the preparation and analysis. ND Non-detect-Result was below the DQO listed for the analyte. <'/. :High Sample Background-Spike concentration was less than one forth of the sample concentration. DQO Data Quality Objective-This is the criteria against which the quality control data is com ared. Explanation 435 :Sample matrix may be affecting this analyte.Data was accepted based on the LCS or CCV recovery. 440 Sample nonhomogeneity may be affecting this analyte.Data was accepted based on the LCS or CCV recovery. 735 Dilution water exceeded DO uptake method criteria Page 7 of 7
