Matrix Spike (MS)Preparation/Analytical Method Verification The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories, LLC. and with guidance from the regulatory documents listed in this "Method/Analysis Information" section.System Confiigurntion The ICP analysis was performed on a Perkin Elmer 4300 Optima radial/axial-viewing 11 inductively coupled plasma atomic emission spectrometer.

The instrument is equipped with a Burgener nebulizer, cyclonic spray chamber, and yttrium or scandium internal standard.

Operating conditions for the ICP are set at a power level of 1500 watts. The instrument has a peristaltic pump flow rate of 1.4IUmin, argon gas flows of 15 Iimin and 0.2 Llmin for the torch and auxiliary gases, and a flow setting of 0.65L/min for the nebulizer.

Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.ICSA/ICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.Quality Control (OC) Information Method Blank (MB) Statement The MB analyzed with this SDG met the acceptance criteria.Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.Quality Control (QC) Sample Statement The following sample was selected as the QC sample for this batch: 122228002 (MWI OOD-0304-001).

Matrix Spike (MS) Recovery Statement The percent recoveries

(%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria.Matrix Spike Duplicate (MSD) Recovery Statement The percent recovery (%R) obtained from the MSD analyses are evaluated when the 12 sample concentration is less than four time (4X) the spike concentration added. All applicable elements met the acceptance criteria.MS/MSD Relative Percent Difference (RPD) Statement The RPD(s) between the MS and MSD met the acceptance limits.Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20% when the sample is >5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement.

Raw element concentrations that are 25X the IDL for CVAA, 50X the IDL for ICP, and I OOX the IDL for ICP-MS analyses are applicable for serial dilution assessment.

All applicable analytes met the acceptance criteria of less than 10% difference

(%D).Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt. Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration.

All samples in this SDG met the specified holding time.Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.Sample Dilutions Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples and/or to bring over range target analyte concentrations into the linear calibration range of the instrument.

The samples in this SDG did not require dilutions.

The instrument is equipped with a Burgener nebulizer, cyclonic spray chamber, and yttrium or scandium internal standard.

Operating conditions for the ICP are set at a power level of 1500 watts. The instrument has a peristaltic pump flow rate of 1 .4Umin, argon gas flows of 15 Linin and 0.2 L/min for the torch and auxiliary gases, and a flow setting of 0.65TJ'min for the nebulizer.

The ICP-MS analysis was performed on a Perkin Elmer ICP-MS ELAN 9000. The instrument is equipped with a cross-flow nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier detector.

Internal standards of scandium, germanium, indium, and tantalum were utilized to cover the mass spectrum.

Operating conditions are set at 1400W power and combined argon pressures of 3607 kPa for the plasma and auxiliary gases, and 0.85 UImin carrier gas flow, and an initial lens voltage of 5.2.Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.ICSAJICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.Ouality Control (OC) Information Method Blank (MB) Statement The MBs analyzed with this SDG met the acceptance criteria.Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.9 Quality Control (QC) Sample Statement The following sample was selected as the quality control (QC) sample for this batch: 122032001 (MW505-0304-001).

Matrix Spike (MS) Recovery Statement The percent recoveries

(%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria.Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20% when the sample is >5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement.

Raw element concentrations that are 25X the IDL for CVAA, 50X the IDL for ICP, and lOOX the IDL for ICP-MS analyses are applicable for serial dilution assessment.

All applicable analytes met the acceptance criteria of less than 10% difference

To minimize this interference, the salts are converted to oxides by heating the sample under a flame until a dull red color is obtained.

The conversion to oxides stabilizes the sample weight and ensures that proper alpha/beta efficiencies are assigned for each sample. Volatile radioisotopes of carbon, hydrogen, technetium, polonium and cesium may be lost during sample heating.Miscellaneous Information:

Sample Duplicate (DUP)122411001(MW107S-0304-001 S) Matrix Spike (MS)Preparation/Analytical Method Verification The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories, LLC. and with guidance from the regulatory documents listed in this 'Method/Analysis Information" section.11 System Confluration The ICP-MS analysis was performed on a Perkin Elmer ICP-MS ELAN 9000. The instrument is equipped with a cross-flow nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier detector.

Internal standards of scandium, germanium, indium, and tantalum were utilized to cover the mass spectrum.

Operating conditions are set at 1400W power and combined argon pressures of 3607 kPa for the plasma and auxiliary gases, and 0.85 L/min carrier gas flow, and an initial lens voltage of 5.2.Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.ICSA/ICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.Oualitv Control (0() Information Method Blank (MB) Statement The MB analyzed with this SDG met the acceptance criteria.Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.Quality Control (QC) Sample Statement The following sample was selected as the quality control (QC) sample for this batch: 122411001 (MW107S-0304-001).

Matrix Spike (MS) Recovery Statement The percent recoveries

(%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria.12 Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20% when the sample is >5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement.

Raw element concentrations that are 25X the IDL for CVAA, 50X the IDL for ICP, and IOOX the IDL for ICP-MS analyses are applicable for serial dilution assessment.

All applicable analytes met the acceptance criteria of less than 10% difference

(%D).Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt. Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration.

All samples in this SDG met the specified holding time.Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.Sample Dilutions Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples and/or to bring over range target analyte concentrations into the linear calibration range of the instrument.

The samples in this SDG did not require dilutions.

Preparation Information The samples in this SDG were prepared exactly according to the cited SOP.Miscellaneous Information Nonconformance Documentation Nonconformance reports (NCRs) are generated to document procedural anomalies that may deviate from referenced SOP or contractual documents.

A NCR was not required for this SDG.Additional Comments Additional comments were not required for this SDG.Certification Statement 13 Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

Review Validation GEL requires all analytical data to be verified by a qualified data validator.

In addition, all data designated for CLP or CLP-like packaging will receive a third level validation upon completion of the data package.The following data validator verified the Information presented in this case narrative:

Holding Time All sample procedures for this sample set were performed within the required holding time.Preparation Information All preparation criteria have been met for these analyses.Sample Re-prep/Re-analysis None of the samples in this sample set required reprep or reanalysis.

Chemical Recoveries All chemical recoveries meet the required acceptance limits for this sample set.Gross Alpha/Beta Preparation Information High hygroscopic salt content in evaporated samples can cause the sample mass to fluctuate due to moisture absorption.

To minimize this interference, the salts are converted to oxides by heating the sample under a flame until a dull red color is obtained.

The conversion to oxides stabilizes the sample weight and ensures that proper alpha/beta efficiencies are assigned for each sample. Volatile radioisotopes of carbon, hydrogen, technetium, polonium and 31 cesium may be lost during sample heating.Miscellaneous Information:

Matrix Spike (MS)Preparation/Analytical Method Verification The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories.

LLC. and with guidance from the regulatory documents listed in this "Method/Analysis Information" section.12 System Configuration The ICP-MS analysis was performed on a Perkin Elmer ICP-MS ELAN 9000. The instrument is equipped with a cross-flow nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier detector.

Internal standards of scandium, germanium, indium, and tantalum were utilized to cover the mass spectrum.

Operating conditions are set at 1400W power and combined argon pressures of 3607 kPa for the plasma and auxiliary gases, and 0.85 UImin carrier gas flow, and an initial lens voltage of 5.2.Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.ICSA/ICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.Oualitv Control (OC) Information Method Blank (MB) Statement The MB analyzed with this SDG met the acceptance criteria.Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.Quality Control (QC) Sample Statement The following sample was selected as the quality control (QC) sample for this SDG: 122411001 (MWI07S-0304-001).

Matrix Spike (MS) Recovery Statement The percent recoveries

(%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria.13 Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20% when the sample is >5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement.

Raw element concentrations that are 25X the IDL for CVAA, 50X the IDL for ICP, and lOOX the IDL for ICP-MS analyses are applicable for serial dilution assessment.

All applicable analytes met the acceptance criteria of less than 10% difference

(%D).Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt. Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration.

All samples in this SDG met the specified holding time.Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.Sample Dilutions Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples and/or to bring over range target analyte concentrations into the linear calibration range of the instrument.

The samples in this SDG did not require dilutions.

Preparation Information The samples in this SDG were prepared exactly according to the cited SOP.Miscellaneous Information Nonconformance Documentation Nonconformance reports (NCRs) are generated to document procedural anomalies that may deviate from referenced SOP or contractual documents.

A NCR was not required for this SDG.Additional Comments Additional comments were not required for this SDG.Certification Statement Where the analytical method has been performed under NELAP certification, the analysis 14 has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

Review Validation:

GEL requires all analytical data to be verified by a qualified data validator.

In addition, all data designated for CLP or CLP-like packaging will receive a third level validation upon completion of the data package.The following data validator verified the information presented in this case narrative:

The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories, LLC. and with guidance from the regulatory documents listed in this "Method/Analysis Information" section.System Confiuration The ICP analysis was performed on a Perkin Elmer 4300 Optima radial/axial-viewing inductively coupled plasma atomic emission spectrometer.

The instrument is equipped with a Burgener nebulizer, cyclonic spray chamber, and yttrium or scandium internal standard.

Operating conditions for the ICP are set at a power level of 1500 watts. The instrument has a peristaltic pump flow rate of 1 AL/min, argon gas flows of 15 Iimin and 0.2 Lmnin for the torch and auxiliary gases, and a flow setting of 0.65J/min for the nebulizer.

Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.ICSAIICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.Continuing Calibration Veriflication (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.Oualitv Control (OC) Information Method Blank (MB) Statement The MB analyzed with this SDG met the acceptance criteria.Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.Quality Control (QC) Sample Statement The following sample was selected as the quality control (QC) sample for this batch: 122669001 (MW108S-0304-001).

10 Matrix Spike (MS) Recovery Statement The percent recoveries

(%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria.Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20% when the sample is >5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement.

Raw element concentrations that are 25X the IDL for CVAA, 50X the IDL for ICP, and IOOX the IDL for ICP-MS analyses are applicable for serial dilution assessment.

All applicable analytes except potassium and sodium met the acceptance criteria of less than 10% difference

(%D).Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt. Those holding times expressed in hours are calculated in the AlphaLlMS system. Those holding times expressed as days expire at midnight on the day of expiration.

All samples in this SDG met the specified holding time.Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.Sample Dilutions Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples and/or to bring over range target analyte concentrations into the linear calibration range of the instrument.

The samples in this SDG did not require dilutions.

Preparation Information The samples in this SDG were prepared exactly according to the cited SOP.Miscellaneous Information Nonconformance Documentation Nonconformance reports (NCRs) are generated to document procedural anomalies that may deviate from referenced SOP or contractual documents.

A NCR was not required for this SDG.11 Additional Comments Additional comments were not required for this SDG.Certification Statement Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

Review Validation GEL requires all analytical data to be verified by a qualified data validator.

In addition, all data designated for CLP or CLP-like packaging will receive a third level validation upon completion of the data package.The following data validator verified the information presented In this case narrative:

Matrix Spike (MS)Preparation/Analytical Method Verification The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories, LLC. and with guidance from the regulatory documents listed in this "Method/Analysis Information" section.9 System Configuration The ICP-MS analysis was performed on a Perkin Elmer ICP-MS ELAN 9000. The instrument is equipped with a cross-flow nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier detector.

Internal standards of scandium, germanium, indium, and tantalum were utilized to cover the mass spectrum.

Operating conditions are set at 1400W power and combined argon pressures of 3607 kPa for the plasma and auxiliary gases, and 0.85 Iimin carrier gas flow, and an initial lens voltage of 5.2.Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.ICSAIICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.Quality Control (OC) Information Method Blank (MB) Statement The MB analyzed with this SDG met the acceptance criteria.Laboratory Control Sample (LCS) Recovery The LCS spike recoveries met the acceptance limits.Quality Control (QC) Sample Statement The following sample was selected as the quality control (QC) sample for this batch: 123271001 (MWI04S-0304-001) from another SDG Matrix Spike (NIS) Recovery Statement The percent recoveries

(%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria.10 Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20% when the sample is >5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement.

Raw element concentrations that are 25X the IDL for CVAA, 50X the IDL for ICP, and IOOX the IDL for ICP-MS analyses are applicable for serial dilution assessment.

All applicable analytes met the acceptance criteria of less than 10% difference

(%D).Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt. Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration.

All samples in this SDG met the specified holding time.Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.Sample Dilutions Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples and/or to bring over range target analyte concentrations into the linear calibration range of the instrument.

The samples in this SDG did not require dilutions.

Preparation Information The samples in this SDG were prepared exactly according to the cited SOP.Miscellaneous Information Nonconformance Documentation Nonconformance reports (NCRs) are generated to document procedural anomalies that may deviate from referenced SOP or contractual documents.

A NCR was not required for this SDG.Additional Comments Additional comments were not required for this SDG.Certification Statement 11 Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

Review Validation GEL requires all analytical data to be verified by a qualified data validator.

In addition, all data designated for CLP or CLP-like packaging will receive a third level validation upon completion of the data package.The following data validator verified the information presented in this case narrative:

The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories, LLC. and with guidance from the regulatory documents listed in this 'Method/Analysis Information" section.System Confieuration The ICP analysis was performed on a Perkin Elmer 4300 Optima radial/axial-viewing inductively coupled plasma atomic emission spectrometer.

The instrument is equipped with a Burgener nebulizer, cyclonic spray chamber, and yttrium or scandium internal standard.

Operating conditions for the 1CP are set at a power level of 1500 watts. The instrument has a peristaltic pump flow rate of 1.4Lmin, argon gas flows of 15 Uimin and 0.2 Uimin for the torch and auxiliary gases, and a flow setting of 0.65lJmin for the nebulizer.

The lCP-MS analysis was performed on a Perkin Elmer ICP-MS ELAN 9000. The instrument is equipped with a cross-flow nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier detector.

Internal standards of scandium, germanium, indium, and tantalum were utilized to cover the mass spectrum.

Operating conditions are set at 1400W power and combined argon pressures of 3607 kPa for the plasma and auxiliary gases, and 0.85 L'min carrier gas flow, and an initial lens voltage of 5.2.Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.ICSAIICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.Ouality Control (OC) Information Method Blank (MB) Statement The MB analyzed with this SDG met the acceptance criteria.9 Laboratory Control Sample (LCS) Recovery The LOS spike recoveries met the acceptance limits.Quality Control (QC) Sample Statement The following sample was selected as the quality control (QC) sample for this batch: 123271001 (MW104S-0304-001).

Matrix Spike (MS) Recovery Statement The percent recoveries

(%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria.Matrix Spike Duplicate (MSD) Recovery Statement The percent recovery (%R) obtained from the MSD analyses are evaluated when the sample concentration is less than four time (4X) the spike concentration added. All applicable elements met the acceptance criteria.MSIMSD Relative Percent Difference (RPD) Statement The RPD(s) between the MS and MSD met the acceptance limits.Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20% when the sample is >5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RI, a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement.

Raw element concentrations that are 25X the IDL for CVAA, 50X the IDL for ICP, and lOOX the IDL for ICP-MS analyses are applicable for serial dilution assessment.

All applicable analytes met the acceptance criteria of less than 10% difference

(%D) except boron.Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt. Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration.

All samples in this SDG met the specified holding time.Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.Sample Dilutions 10 Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples andlor to bring over range target analyte concentrations into the linear calibration range of the instrument.

The samples in this SDG did not require dilutions.

Preparation Information The samples in this SDG were prepared exactly according to the cited SOP.Miscellaneous Information Nonconformance Documentation Nonconformance reports (NCRs) are generated to document procedural anomalies that may deviate from referenced SOP or contractual documents.

A NCR was not required for this SDG.Additional Comments Additional comments were not required for this SDG.Certification Statement Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

It the recount is inconclusive please analyze another representative sample for gamma isotopic constituents.

4. Can you Il erlorm uranium isotopic analysis on the ollowing samples? We are particularly Interested In evaluating the U-2341L238 and U-235vU-238 ratios to distinguish natural enric iment from potential 3-5% enriched U levels. I think you may have to analyze by ICP-MS to get the desired sensitivity

Matrix Spike (MS)Preparation/Analytical Method Verification 15 The SOP stated above has been prepared based on technical research and testing conducted by General Engineering Laboratories, LLC. and with guidance from the regulatory documents listed in this '%Method/Analysis Information" section.System Confieuration The ICP-MS analysis was performed on a Perkin Elmer ICP-MS ELAN 9000. The instrument is equipped with a cross-flow nebulizer, quadrupole mass spectrometer, and dual mode electron multiplier detector.

Internal standards of scandium, germanium, indium, and tantalum were utilized to cover the mass spectrum.

Operating conditions are set at 1400W power and combined argon pressures of 3607 kPa for the plasma and auxiliary gases, and 0.85 Iimin carrier gas flow, and an initial lens voltage of 5.2.Calibration Information Instrument Calibration All initial calibration requirements have been met for this sample delivery group (SDG).CRDL Requirements All CRDL standard(s) met the referenced advisory control limits.ICSAJICSAB statement All interference check samples (ICSA and ICSAB) associated with this SDG met the established acceptance criteria.Continuing Calibration Blank (CCB) Requirements All continuing calibration blanks (CCB) bracketing this batch met the established acceptance criteria.Continuing Calibration Verification (CCV) Requirements All continuing calibration verifications (CCV) bracketing this SDG met the acceptance criteria.Oualitv Control (OC) Information Method Blank (MB) Statement The MBs analyzed with this SDG met the acceptance criteria.Laboratory Control Sample (LCS) Recovery The LWS spike recoveries met the acceptance limits.Quality Control (QC) Sample Statement The following sample was selected as the quality control (QC) sample for this batch: 127165001 (MW102S-0304-001).

Matrix Spike (MS) Recovery Statement 16 The percent recoveries

(%R) obtained from the MS analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. All applicable elements met the acceptance criteria Duplicate Relative Percent Difference (RPD) Statement The RPD obtained from the designated sample duplicate (DUP) is evaluated based on acceptance criteria of 20% when the sample is >5X the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control of RL is used to evaluate the DUP results. All applicable analytes met these requirements.

Serial Dilution % Difference Statement The serial dilution is used to assess matrix suppression or enhancement.

Raw element concentrations that are 25X the IDL for CVAA, 50X the IDL for ICP, and lOOX the IDL for ICP-MS analyses are applicable for serial dilution assessment.

All applicable analytes met the acceptance criteria of less than 10% difference

(%D).Technical Information Holding Time Specifications GEL assigns holding times based on the associated methodology, which assigns the date and time from sample collection of sample receipt. Those holding times expressed in hours are calculated in the AlphaLIMS system. Those holding times expressed as days expire at midnight on the day of expiration.

All samples in this SDG met the specified holding time.Preparation/Analytical Method Verification All procedures were performed as stated in the SOP.Sample Dilutions Dilutions are performed to minimize matrix interferences resulting from elevated mineral element concentrations present in soil samples and/or to bring over range target analyte concentrations into the linear calibration range of the instrument.

The samples in this SDG did not require dilutions.

Preparation Information The samples in this SDG were prepared exactly according to the cited SOP.Miscellaneous Information Nonconformance Documentation Nonconformance reports (NCRs) are generated to document procedural anomalies that may deviate from referenced SOP or contractual documents.

A NCR was not required for this SDG.Additional Comments Additional comments were not required for this SDG.17 Certification Statement Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless otherwise noted in the analytical case narrative.

Review Validation GEL requires all analytical data to be verified by a qualified data validator.

In addition, all data designated for CLP or CLP-like packaging will receive a third level validation upon completion of the data package.The following data validator verified the information presented in this case narrative:

In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/-the RL is used to evaluate the DUP result.For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.Page 16 of 16 70
