CCB :Continuing Calibration Bunk-Analyzed to verify the instrument baseline is vrithin criteria. i; t 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 Controi Staadard/Sample-Prepared to verify that:hc 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 analyic recovery. ;; a MSD Matrix Spike Duplicate cf y1SfVlSD pair-A random sample duplicate is spiked with a knoari amount of analyted.The recoveries arc an indication of how that sumple matrix affects analyte recovery. Dup :Duplicate Sample-A random sample with each batch is prepared and analyzed in duplicate.The relative percent dif femnce is an indication of precision for the preparation and analysis- MSRPD :MS/MSD Relative Percent Difference(RPD)-The MS relative percent difference,i<s an indicatim of precision for the preparation i and analysis. ND :Vion-deteet-Result Nvas below the DQO listed for the analyte. <'/ :High Semple Background-Spike conecniration was less than one forth ofthe sample canecrt[ration. O :Data Quality Objective-This is the criteria a ainst which the guality control data is compared, Explanaliion 435 :Sample matrix ma be affcctin'-this analyte-Data was accepted based on the LCS or CCV recovery. :i E; I t� :1 f ' i E i i Page 6 of 6
