Continuing Calibration Verification (CCV) Requirements <br /> All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria. <br /> Quality Control (QC) Information <br /> Method Blank (MB) Statement <br /> The MBs analyzed with this SDG met the acceptance criteria. <br /> Laboratory Control Sample (LCS) Recovery <br /> The LCS spike recoveries met the acceptance limits. <br /> Quality Control (QC) Sample Statement <br /> The following samples were selected as the quality control (QC) samples for this SDG: <br /> 344616001 (Sunday MW 1)-ICP, 344616002 (Sunday MW 1D)-ICP-MS and 344539001 <br /> (LMP 1402001Z4)-CVAA. <br /> Matrix Spike (MS) Recovery Statement <br /> The percent recoveries (%R) obtained from the MS analyses are evaluated when the sample <br /> concentration is less than four times (4X) the spike concentration added. All applicable elements <br /> met the acceptance criteria. <br /> Duplicate Relative Percent Difference (RPD) Statement <br /> The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance <br /> criteria of 20% when the sample is >5X the contract required reporting limit (RL). In cases <br /> where either the sample or duplicate value is less than 5X the RL, a control of+/-RL is used to <br /> evaluate the DUP results. All applicable analytes met these requirements. <br /> Serial Dilution % Difference Statement <br /> The serial dilution is used to assess matrix suppression or enhancement. Raw element <br /> concentrations 25x the IDL/MDL for CVAA, 50X the IDL/MDL for ICP and 100X the <br /> IDL/MDL for ICP-MS analyses are applicable for serial dilution assessment. All applicable <br /> analytes met the established acceptance criteria. <br /> Technical Information <br /> Holding Time Specifications <br /> GEL assigns holding times based on the associated methodology, which assigns the date and <br /> time from sample collection of sample receipt. Those holding times expressed in hours are <br /> calculated in the A1phaLIMS system. Those holding times expressed as days expire at midnight <br /> on the day of expiration. All samples in this SDG met the specified holding time. <br /> Preparation/Analytical Method Verification <br /> All procedures were performed as stated in the SOP. <br /> Sample Dilutions <br /> Dilutions are performed to minimize matrix interferences resulting from elevated mineral <br /> Page 20 of 94 <br />
