SVOC - SB-905-20-22 - One surrogate was out for this sample. Sample was reanalyzed but outside of holding time. Results reported from the first sample and qualified based on surrogates. No qualifiers required for holding times since those results were not reported. Sample results were compared against each other and all original results were greater than the second analysis except for butylbenzylphthalate. Based on professional judgement it was decided to use the second analysis result for this sample since the first one was nondetect and the second result was detect.

DATA VALIDATION SUMMARY GED - ISOCS (1-4-16) - Radiochemistry GAMMA SPECTROMETRY - (Radium-226, Thorium-232, Uranium-238) SUMMARY I.) General: The laboratory has cited GED SOP 4.9 for the Field Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: All Sample Receipt, Preparation and Holding Time criteria were met. No data qualification was necessary. Sample Preparation: Note: Radium-226 is reported in these samples from the daughter progeny, Bismuth-214 and Lead-214. Due to the nature and intended use of ISOCS analyses/data for Radium-226, the samples were not sealed for the typical 21-day ingrowth period prior to gamma counting per EPA method 901.1. The Bismuth-214 and Lead-214 results are potentially biased low. Since the project/stakeholders are aware of this approach and the limitations of the resulting data, and this part of the WACC project is in the remedial investigation stage, validation qualifiers will not be applied to Radium-226 results due to ingrowth periods less than 21 days. II.) Calibration: All Calibration criteria were met. No action was required. III.) Background Level: A Background check was performed prior to sample analyses. All Background Level criteria were met. No action was required.

IV.) Instrument Performance / Laboratory Control Sample (LCS): The LCS recovery of 129% for Uranium-238 was above the QC limit of 75-125%, indicating a potential high bias for the Uranium-238 sample results. All SDG Uranium-238 results were non-detected; therefore, did not require qualification. All other Instrument Performance (LCS) criteria were met. V.) Blanks: Method Blank (MB): Method Blanks are not applicable to field gamma spectrometry analyses. No action was needed. VI.) Laboratory Replicate (QC): Replicate analyses were performed on SDG samples SWSB07-1618 (1-4-16) and SWSB904-0406 (1-4-16) for the soil samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory precision for the sample matrix. Non-detected results were not evaluated.

In the second set of FD samples, the Thorium-232 Z-score was above the |Z| < 1.96 QC limit. The associated Thorium-232 sample results, which were both detected, were qualified as estimated (J). The associated samples were: SWSB04-0406 (12-22-15) and SWSB04-0406 (12-22-15). The parent sample SWSB04-0406 was analyzed (and qualified) in SDG ISOCS (12-22-15). Parent samples SWSB03-0204 and SWSB09-0204 were analyzed in SDGs ISOCS (12-17-15) and ISOCS (12-22-15). All other Z-score results were within the |Z| < 1.96 QC limit. No further action was needed. VIII.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. IX.) Required Detection Limits (RDLs) and Detection Decisions: Required Detection Limits: The sample isotope detection limits (MDAs) for Radium-226, Thorium-232, and Uranium-238 were less than their respective RDLs. No data qualification was required. Detection Decisions: All reported sample results that were less than their sample-specific MDA were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. X.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CU. No data qualification was required. XI.) Calculation / Transcription Verification: This criterion was not evaluated for Level III.

Instrument Performance / Laboratory Control Sample (LCS): The LCS recovery of 133% for Uranium-238 was above the QC limit of 75-125%, indicating a potential high bias for the Uranium-238 sample results. All SDG Uranium-238 results were non-detected; therefore, did not require qualification. All other Instrument Performance (LCS) criteria were met. V.) Blanks: Method Blank (MB): Method Blanks are not applicable to field gamma spectrometry analyses. No action was needed. VI.) Laboratory Replicate (QC): There were no QC samples identified for this fraction of the SDG. QC samples have been analyzed at the project-specified frequency of 10% of the field samples, so no action was taken. VII.) Field Duplicate (FD): There were no FD samples identified for this fraction of the SDG. FD samples have been analyzed at the project-specified frequency of 5% of the field samples, so no action was taken. VIII.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. IX.) Required Detection Limits (RDLs) and Detection Decisions: Required Detection Limits: The sample isotope detection limits (MDAs) for Radium-226, Thorium-232, and Uranium-238 were less than their respective RDLs. No data qualification was required. Detection Decisions: All reported sample results that were less than their sample-specific MDA were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. X.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CU.

DATA VALIDATION SUMMARY American Radiation Services – SDG: ARS1-15-02690 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: All Sample Receipt, Preparation and Holding Time criteria were met. No data qualification was necessary. Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample density (d) was not representative of the calibration standard density (d) of the 250 ml tuna can geometry (1595-98-4):

Client Sample Cal Std (d) Sample (d) % D SED-EB08-07-08 1.5 g/cc 1.041 g/cc 30.6

The low sample density indicates a potential high bias for the sample results due to decreased sample attenuation / self-absorption relative to that of the calibration standard density. For this reason, using professional judgment, the detected Potassium-40, Radium-226, and Thorium-232 results for the above listed sample are potentially biased high and were qualified as estimated (J).

All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-EB08-00-0.5 (ARS1-15-02690-002DUP) for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

VIII.) Field Duplicate (FD): There were no field duplicate samples identified for this fraction of the SDG. Data qualification based on the absence of field duplicate data was not required, so no action was taken. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): The sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty: All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required.

ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General: The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results. The validator expected the results to be more similar than what was reported. Ninety percent of the Thorium-232 results by gamma spec were higher than the alpha spec results. The laboratory provided sample spectra of the Thorium analyses in the data package. Without an MCA or PC available to allow the validator to evaluate the sample spectra electronically, printed spectra are the only recourse. After evaluating the alpha spectrometry sample spectra, it was observed that the regions of interests (ROIs) chosen by the instrument software may not be including the entire Thorium-232 peak area. Thorium-232 has a 24% abundant peak at 3.95 MeV and a 76% abundant peak at 4.01 MeV. It appears that the software ROI is not including most if not all of the 24% abundant peak. It was also observed when the peak shape was broader than normal (FWHM), the software ROI would not include all of the 76% abundant peak as well. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. Perhaps a closer inspection of the sample spectra and manual integration of the peaks may be in order. Although most of the Thorium-232 results were below the project action limit of 5.0 pCi/g, the validator wanted the data users to be informed of this possible anomaly.

The re-integrated Thorium-232 results produced slightly higher results by alpha spec as expected, but ninety percent of the Thorium-232 results by gamma spec were still higher than the alpha spec results. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. MAJOR ISSUES No major issues were encountered in this fraction of the SDG.

DATA VALIDATION SUMMARY American Radiation Services – SDG: ARS1-15-02691 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: See major issues section below for rejected data. All other laboratory data were acceptable with qualifications. MAJOR ISSUES I.) Sample Preparation: The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometry (1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) % D SED-EB01-00-0.5 136.45 g 1.5 g/cc 0.546 g/cc 63.6 SED-EB04-00-0.5 143.52 g 1.5 g/cc 0.574 g/cc 61.7

The extremely low sample densities and/or volume differences indicate a severe bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples were qualified as rejected (R). No other major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228.

The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometry (1595-98-4):

Client Sample Sample (wt.) Cal Std (d) Sample (d) % D SED-EB01-04-05 227.46 g 1.5 g/cc 0.910 g/cc 39.3 SED-EB01-05-06 214.25 g 1.5 g/cc 0.857 g/cc 42.9

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples are potentially biased; therefore, detected results were qualified as estimated (J) and non-detected results were qualified as estimated (UJ). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. All LCS criteria were met. No action was required.

VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-EB01-01-02 (ARS1-15-02691-004DUP) for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

Duplicate Sample Prep Batch Isotope Z-score SED-EB01-01-02 B15-03469 Potassium-40 1.88 Radium-226 0.05 Thorium-232 0.22

The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. VIII.) Field Duplicate (FD): One set of FD samples was identified for this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the field sampling and laboratory precision for the sample matrix.

Parent Sample Duplicate Sample Isotope Z-score SED-EB01-08-09 SED-EB901-08-09 Potassium-40 1.59 Radium-226 0.61 Thorium-232 3.53

The Thorium-232 Z-score result was above the |Z| < 1.96 QC limit. The associated Thorium-232 sample results, which were both detected, were qualified as estimated (J). The 2 associated samples were SED-EB01-08-09 and SED-EB901-08-09. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): The following sample isotope detection limit exceeded the project Required Detection Limit (RDL):

4

Isotope Client Sample ID Sample MDC Project RDL Radium-226 SED-EB01-05-06 0.798 pCi/g 0.7 pCi/g

The detected sample isotope result for Radium-226 did not warrant qualification since the result was several times higher than the MDC. All other sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General: The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications.

Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results. The validator expected the results to be more similar than what was reported. Both alpha and gamma spectra and/or peak reports were evaluated. It was noted that both Uranium and Thorium tracer recoveries were lower than typical, but acceptable. After evaluating the alpha spectrometry sample spectra, it was observed that the regions of interests (ROIs) chosen by the instrument software may not be including the entire Thorium-232 peak area for some of the samples. Thorium-232 has a 24% abundant peak at 3.95 MeV and a 76% abundant peak at 4.01 MeV. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. In some cases, the higher alpha spec results could be contributed to tailing and poor resolution (due to high sample activities and/or matrix interference) which expanded the peak regions of interest (ROIs). A quick gamma scan of the sample could help the laboratory technician to select an appropriate sample aliquant prior to the start of the alpha spec sample processing.

After the Thorium spectra were re-integrated, there were only 4 samples that had RPDs greater than 50%, whereas originally there were 7. Of those 4 samples 2 gamma results were higher and 2 alpha results were higher. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: All Sample Receipt, Preparation and Holding Time criteria were met. No action was necessary. Sample Preparation Note: Multiple preparation batches were used in the isotopic analyses. Below is a clarification of the prep batches. Isotopic Uranium – prep batch B15-03361 was the original prep batch for the 20 SDG samples. Five of the samples were reanalyzed in prep batch B15-03425 for low tracer recoveries. Isotopic Thorium – prep batch B15-03350 was the original prep batch for the 20 SDG samples. Three samples were reported from this batch and the rest were reanalyzed in prep batch 15-03461 due to method blank contamination. Three of these RE samples were reanalyzed in prep batch B15-03576 due to low tracer recoveries. One sample still had low tracer recovery and was reported and qualified by the laboratory.

Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for each preparation batch associated with this fraction of the SDG. In MB ARS1-B15-03361-03, the Uranium-234 activity of 0.100 pCi/g was above its sample-specific MDC of 0.095 pCi/g. The Uranium-238 activity of 0.132 pCi/g was above its sample-specific MDC of 0.099 pCi/g.

SED-EB04-04-05 0.545 5.94 Pass ZDER was calculated to determine the relative difference of sample isotope results with the failed blank isotope results. The Uranium-238 ZDER of 2.12 for sample SED-EB01-09-10 was below the QC limit of ZDER > 2.58, indicating potential blank contamination bias; therefore, the Uranium-238 result was qualified as estimated (J). The remaining affected detected sample results for Uranium-234and Uranium-238 in the associated samples were demonstrated to be significantly different (ZDER > 2.58); therefore, further data qualification was not required. The remaining SDG samples for isotopic Uranium were reanalyzed in prep batch 15-0325 for low yields and elevated MDCs (Please see below). In MB ARS1-B15-03350-03, the Thorium-230 activity of 0.104 pCi/g was above its sample-specific MDC of 0.059 pCi/g. The associated samples that had detections for Thorium-230 were evaluated for potential blank contamination bias. ZDER was calculated to determine the relative difference of sample isotope results with the failed blank isotope result. The affected detected sample results for Thorium-230 in the associated samples were demonstrated to be significantly different (ZDER > 2.58); therefore, data qualification was not required. The remaining SDG samples for isotopic Thorium were reanalyzed in prep batch B15-03461 with acceptable method blank results. All other isotope detections were less than their sample-specific MDCs associated with this fraction of the SDG. No further action was taken. Equipment Blank: Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for each preparation batch for the sediment samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-EB03-08-09 (ARS1-15-02691-001DUP) for the preparation batch containing 15 of the sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

DATA VALIDATION SUMMARY American Radiation Services – SDG: ARS1-15-02699 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: See major issues section below for rejected data. All other laboratory data were acceptable with qualifications. MAJOR ISSUES I.) Sample Preparation: The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometry (1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) % D SED-EB07-09-10 177.37 g 1.5g/cc 0.709 g/cc 52.7 SED-EB05-0.5-01 156.63 g 1.5 g/cc 0.627 g/cc 58.2 SED-EB05-00-0.5 92.31 g 1.5 g/cc 0.369 g/cc 75.4

The extremely low sample densities and/or volume differences indicate a severe bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples were qualified as rejected (R). No other major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and

2

the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometries (1595-98-4, 1559-72-6, 1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) % D SED-EB07-05-06 243.47 g 1.5 g/cc 0.974 g/cc 35.1 SED-EB07-06-07 249.21 g 1.5 g/cc 0.997 g/cc 33.5 SED-EB07-07-08 222.73 g 1.5 g/cc 0.891 g/cc 40.6 SED-EB07-08-09 218.07 g 1.5 g/cc 0.872 g/cc 41.9 SED-EB05-01-02 197.86 g 1.5 g/cc 0.791 g/cc 47.3 SED-EB05-02-03 203.58 g 1.5 g/cc 0.814 g/cc 45.7

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples are potentially biased; therefore, detected results were qualified as estimated (J) and non-detected results were qualified as estimated (UJ). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken.

Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-EB04-06-07 (ARS1-15-02699-002DUP) for the preparation batch containing the 20 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.


The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. VIII.) Field Duplicate (FD): A FD sample was identified for this fraction of the SDG. The parent sample was analyzed in SDG ARS1-15- 02691. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the field sampling and laboratory precision for the sample matrix.


The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required.

XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): All sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty: All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General: The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses.

II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results. The validator expected the results to be more similar than what was reported. It was noted that both Uranium and Thorium tracer recoveries were lower than typical, but acceptable. 14 of the 20 Thorium-232 results by gamma spec were higher than the alpha spec results. After evaluating the alpha spectroscopy sample spectra, it was observed that the regions of interests (ROIs) chosen by the instrument software may not be including the entire Thorium-232 peak area for some of the samples. Thorium-232 has a 24% abundant peak at 3.95 MeV and a 76% abundant peak at 4.01 MeV. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. Although all of the Thorium-232 results were below the project action limit of 5.0 pCi/g, the validator wanted the data users to be informed of this possible anomaly.

After the Thorium spectra were re-integrated, eighty-five percent of the Thorium-232 results by gamma spec were still higher than the alpha spec results. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: All Sample Receipt, Preparation and Holding Time criteria were met. No action was necessary. II.)

DATA VALIDATION SUMMARY

American Radiation Services – SDG: ARS1-15-02710 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometries (1559-72-6 and 1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SED-EB05-08-09 238.94 g 1.5 g/cc 0.956 g/cc 36.3 SED-EB02-02-03 259.59 g 1.5 g/cc 1.038 g/cc 30.8 SED-EB06-00-0.5 192.29 g 1.5 g/cc 0.769 g/cc 48.7

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples, which were all detected, were qualified as estimated (J). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification

1

was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for the preparation batch containing the sediment samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the sediment samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-EB02-04-05 (ARS1-15-02710-012DUP) for the preparation batch containing the 19 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

VIII.) Field Duplicate (FD): One set of FD samples was identified for this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the field sampling and laboratory precision for the sample matrix.


The Radium-226 and Thorium-232 Z-score results were above the |Z| < 1.96 QC limit. The associated Radium-226 and Thorium-232 sample results, which were all detected, were qualified as estimated (J). The 2 associated samples were SED-EB02-03-04 and SED-EB902-03-04. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): All sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty:

3

All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General: The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results. The validator expected the results to be more similar than what was reported. 18 of the 19 Thorium-232 results by gamma spec were higher than the alpha spec results. It was noted that the Thorium-229 tracer recoveries were lower than typical, but acceptable. After evaluating the alpha spectroscopy sample spectra, it was observed that the regions of interests (ROIs) chosen by the instrument software may not be including the entire Thorium-232 peak area for some of the samples. Thorium-232 has a 24% abundant peak at 3.95 MeV and a 76% abundant peak at 4.01 MeV. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. Although most of the Thorium-232 results were below the project action limit of 5.0 pCi/g, the validator wanted the data users to be informed of this possible anomaly.

Due to the low tracer recoveries for the above listed samples, the detected and non-detected sample Uranium isotope results (Uranium-234/235/238) were qualified as estimated (J/UJ). Only the reanalysis results were reported by the laboratory on the Form Is and in the EDD. The validator was in agreement with the reporting. All other Thorium-229 and Uranium-232 Tracer Yield criteria were met. No further qualification was necessary. XI.) Nuclide Identification and Interferences: Sample peak energies were within the expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs):

The above non-detected sample isotope results for Uranium-235 were qualified as estimated (UJ) due to sample detection limits exceeding the project required detection limit. All other sample isotope detection limits for Thorium-228/230/232 and Uranium-234/235/238 were less than their respective RDLs. No further data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty: All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL.

American Radiation Services – SDG: ARS1-15-02754 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: See major issues section below for rejected data. All other laboratory data were acceptable with qualifications. MAJOR ISSUES I.) Sample Preparation: The following sample density (d) and/or volume was not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometry (1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SED-EB06-07-08 172.59 g 1.5g/cc 0.690 g/cc 54.0

The extremely low sample density and/or volume difference indicates a potential severe bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed sample were qualified as rejected (R). No other major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228.

The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometries (1559-72-6, 1748-90-1, 1595-72-6):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SED-EB06-05-06 214.31 g 1.5 g/cc 0.857 g/cc 42.9 SED-EB06-06-07 223.60 g 1.5 g/cc 0.894 g/cc 40.4 SED-EB06-08-09 212.78 g 1.5 g/cc 0.851 g/cc 43.3 SED-EB906-06-07 241.38 g 1.5 g/cc 0.966 g/cc 35.6

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples, which were all detected, were qualified as estimated (J). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for the preparation batch containing the sediment samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the sediment samples associated with this fraction of the SDG. All LCS criteria were met. No action was required.

VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-EB06-08-09 (ARS1-15-02754-004DUP) for the preparation batch containing the 6 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.




The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): All sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required.

XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty: All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General: The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results. The validator expected the results to be more similar than what was reported. All 6 of the Thorium-232 results by gamma spec were higher than the alpha spec results. It was noted that the Thorium-229 tracer recoveries were lower than typical, with 4 of the 6 samples being qualified for low tracer recoveries. After evaluating the alpha spectroscopy sample spectra, it was observed that the regions of interests (ROIs) chosen by the instrument software may not be including the entire Thorium-232 peak area for some of the samples. Thorium-232 has a 24% abundant peak at 3.95 MeV and a 76% abundant peak at 4.01 MeV. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec.

Although all of the Thorium-232 results were below the project action limit of 5.0 pCi/g, the validator wanted the data users to be informed of this possible anomaly.

After the Thorium spectra were re-integrated, all of the Thorium-232 results by gamma spec were still higher than the alpha spec results. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: All Sample Receipt, Preparation and Holding Time criteria were met. No action was necessary. II.)

Laboratory Duplicate (DUP): Duplicate analyses were performed on client sample SED-EB06-03-04 (ARS1-15-02710-018DUP) for the preparation batch containing the 6 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.


The Thorium-232 Z-score result was above the |Z| < 1.96 QC limit. The 6 associated Thorium-232 sample results, which were all detected, were qualified as estimated (J). The associated samples were the 6 SDG samples. Duplicate analyses were performed on client sample SED-EB03-09-10 (ARS1-15-02691-002DUP) for the preparation batch containing the 6 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. IX.) Matrix Spike (MS): MS sample analysis was not required since the analytical method utilized a tracer to correct for losses during sample preparation. No action was needed. X.) Chemical Yield (Tracer Recovery): The following Thorium-229 tracer recoveries were below the QC limit of 30%:

Client Sample Prep Batch Tracer Recovery SED-EB06-05-06 B15-03667 Thorium-229 20% SED-EB06-06-07 B15-03667 Thorium-229 13% SED-EB06-07-08 B15-03667 Thorium-229 28% SED-EB06-08-09 B15-03667 Thorium-229 12%

Due to the low tracer recoveries for the above listed samples, the detected and non-detected sample Thorium isotope results (Thorium-228/230/232) were qualified as estimated (J/UJ). The original isotopic Thorium analysis produced low tracer recoveries for all 6 SDG samples. The laboratory provided data for only the reanalysis results. Only the reanalysis results were reported by the laboratory on the Form Is and in the EDD. The validator was in agreement with the reporting. All other Thorium-229 and Uranium-232 Tracer Yield criteria were met. No further qualification was necessary.

The extremely low sample densities and/or volume differences indicate a potential severe bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples were qualified as rejected (R). No other major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to

gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometries (1559-72-6, 1748-90-1, 1595-98-4):

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the detected and non-detected Potassium-40, Radium-226, and Thorium-232 results for the above listed samples were qualified as estimated (J/UJ). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB):

One MB was analyzed for the preparation batch containing the sediment samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the sediment samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-CIC01-02-03 (ARS1-15-02803-004DUP) for the preparation batch containing the 19 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): All sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General:

4

The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results. 12 of the 19 Thorium-232 results by gamma spec were higher than the alpha spec results. Overall the agreement was fair. After evaluating the alpha spectroscopy sample spectra, it was observed that the regions of interests (ROIs) chosen by the instrument software may not be including the entire Thorium-232 peak area for some of the samples. Thorium-232 has a 24% abundant peak at 3.95 MeV and a 76% abundant peak at 4.01 MeV. Although all of the Thorium-232 results were below the project action limit of 5.0 pCi/g, the validator wanted the data users to be informed of this possible anomaly.

ZDER was calculated to determine the relative difference of sample isotope results with the failed blank isotope result. The affected detected sample results for Thorium-228 in the associated samples were demonstrated to be significantly different (ZDER > 2.58); therefore, did not require data qualification. All other isotope detections were less than their sample-specific MDCs associated with this fraction of the SDG. No further action was taken. Equipment Blank: Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed.

VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for each preparation batch for the sediment samples associated with this fraction of the SDG. In LCS ARS1-B15-03580-1, the Uranium-238 recovery of 58% was below the QC limits of 80 -120%, indicating a potential low bias for the Uranium isotopes. For this reason, all associated Uranium-234 and Uranium-238 results, which were all detected, were qualified as estimated (J). All associated Uranium-235 results, which were all non-detected, were qualified as estimated (UJ). The associated samples were: SED-CIC01-01-02, SED-CIC01-04-05, SED-CIC01-05-06, SED-CIC01-06-07, SED-CIC01-08-09, SED-CIC01-09-10, SED-CIC901-01-02, and SED-CIC03-00-0.5. The remaining 11 SDG sediment samples were reanalyzed in prep batch B15-03636 due to low tracer recoveries (Please see below). All other LCS criteria were met. No further action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-CIC01-0.5-01 (ARS1-15-02803-001DUP) for the preparation batch containing 18 of the sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

Duplicate Sample Prep Batch Isotope Z-score SED-CIC01-0.5-01 B15-03631 Thorium-228 0.83 Thorium-230 0.07 Thorium-232 1.45

The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. Sample SED-CIC06-00-0.5 was reanalyzed in prep batch B15-03730 due to low tracer recovery (Please see below). Duplicate analyses were performed on SDG sample SED-CIC06-00-0.5 (ARS1-15-02803-017DUP) for the preparation batch containing the RE sediment sample associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.


The Thorium-230 and Thorium-232 Z-score results were above the |Z| < 1.96 QC limit. The associated Thorium-230 and Thorium-232 results, which were both detected, were qualified as estimated (J). The associated sample was SED-CIC06-00-0.5. For the isotopic Uranium, duplicate analyses were not performed for prep batch B15-03580, containing 8 of the SDG sediment samples. Because of the omission of this required QC element, all associated Uranium-234 and Uranium-238 results, which were all detected, were qualified as estimated (J). All associated

Uranium-235 results, which were all non-detected, were qualified as estimated (UJ). The associated samples were: SED-CIC01-01-02, SED-CIC01-04-05, SED-CIC01-05-06, SED-CIC01-06-07, SED-CIC01-08-09, SED-CIC01-09-10, SED-CIC901-01-02, and SED-CIC03-00-0.5. Duplicate analyses were performed on SDG sample SED-CIC01-0.5-01(ARS1-15-02803-001DUP) for the preparation batch containing the 11 RE sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

The Uranium-238 Z-score result was above the |Z| < 1.96 QC limit for first set of FD samples. The associated Uranium-238 results, which were detected, were qualified as estimated (J). The 2 associated samples were SED-CIC01-01-02 and SED-CIC901-01-02. The Thorium-228 Z-score result was above the |Z| < 1.96 QC limit for second set of FD samples. The associated Thorium-228 results, which were detected, were qualified as estimated (J). The 2 associated samples were SED-CIC06-00-0.5 and SED-CIC906-00-0.5. All other Z-score results were within the |Z| < 1.96 QC limit. No further action was needed.

IX.) Matrix Spike (MS): MS sample analysis was not required since the analytical method utilized a tracer to correct for losses during sample preparation. No action was needed. X.) Chemical Yield (Tracer Recovery): The following Thorium-229 tracer recovery was below the QC limit of 30%:

Client Sample Prep Batch Tracer Recovery SED-CIC06-00-0.5 B15-03631 Thorium-229 5.7%

The sample was reanalyzed in prep batch B15-03730 with acceptable tracer recovery. Only the reanalysis result was reported by the laboratory on the Form I and in the EDD. The validator was in agreement with the reporting. No data qualification was needed. The following Uranium-232 tracer recoveries, despite reanalysis, were below the QC limit of 30%:

Due to the low tracer recoveries for the above listed samples, the detected and non-detected sample Uranium isotope results (Uranium-234/235/238) were qualified as estimated (J/UJ). The laboratory reported the sample results that had the higher tracer recoveries either from the original prep batch (B15-03580) or the RE prep batch (B15-03636). Only one result was reported by the laboratory on the Form Is and in the EDD. The validator was in agreement with the reporting. All other Thorium-229 and Uranium-232 Tracer Yield criteria were met. No further qualification was necessary. XI.) Nuclide Identification and Interferences: The following peak FWHMs were above the QC limit of 100 keV:

Isotope Client Sample ID FWHM Uranium-234 SED-CIC01-05-06 175 Uranium-234 SED-CIC01-06-07 222 Uranium-238 SED-CIC01-06-07 159 Uranium-234 SED-CIC01-08-09 123 Uranium-234 SED-CIC04-00-0.5 140 Uranium-234 SED-CIC05-00-0.5 285 Uranium-238 SED-CIC05-00-0.5 198 Uranium-234 SED-CIC07-00-0.5 135 Uranium-238 SED-CIC07-00-0.5 133

The elevated FWHMs indicate a potential bias to the sample results due to peak tailing and/or poor peak resolution. For this reason, the above listed isotope results, which were all detected, were qualified as estimated (J). All other data validation criteria pertaining to Nuclide Identification and Interferences were met. No further action was necessary. XII.) Required Detection Limits (RDLs): The following sample isotope detection limits exceeded the project Required Detection Limit (RDL):

The above non-detected sample isotope results for Uranium-235 were qualified as estimated (UJ) due to sample detection limits exceeding the project required detection limit. All other sample isotope detection limits for Thorium-228/230/232 and Uranium-234/235/238 were less than their respective RDLs. No further data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U).

11

All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty: All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: There were no discrepancies noted in Calculation / Transcription Verification. No action was required.

American Radiation Services – SDG: ARS1-15-02886 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: See major issues section below for rejected data. All other laboratory data were acceptable with qualifications. MAJOR ISSUES I.) Sample Preparation: The following sample density (d) and/or volume was not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometry (1559-72-6):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SED-CIC02-05-06 174.71 g 1.5 g/cc 0.699 g/cc 53.4

The extremely low sample density and/or volume difference indicates a potential severe bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed sample was qualified as rejected (R). No other major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228.

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples were qualified as estimated (J). The Thorium-232 result for sample SED-CIC02-04-05 was non-detected and qualified as estimated (UJ). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for the preparation batch containing the sediment samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was

needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the sediment samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SED-CIC02-0.5-01 (ARS1-15-02886-002DUP) for the preparation batch containing the 12 sediment samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

Duplicate Sample Prep Batch Isotope Z-score SED-CIC02-0.5-01 B15-03628 Potassium-40 0.37 Radium-226 1.55 Thorium-232 0.82

The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. VIII.) Field Duplicate (FD): There were no FD samples identified for this fraction of the SDG. FD samples have been analyzed at the project-specified frequency of 5% of the field samples, so no action was taken. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): All sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions:

3

All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General: The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results. The validator expected the results to be more similar than what was reported. 9 out of 12 Thorium-232 results by gamma spec were higher than the alpha spec results. It was noted that the Thorium-229 tracer recoveries were lower than typical, but acceptable. After evaluating the alpha spectroscopy sample spectra, it was observed that the regions of interests (ROIs) chosen by the instrument software may not be including the entire Thorium-232 peak area for some of the samples. Thorium-232 has a 24% abundant peak at 3.95 MeV and a 76% abundant peak at 4.01 MeV. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. Although all of the Thorium-232 results were below the project action limit of 5.0 pCi/g, the validator wanted the data users to be informed of this possible anomaly.

After the Thorium spectra were re-integrated, seventy-five percent of the Thorium-232 results by gamma spec were still higher than the alpha spec results. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec. MAJOR ISSUES No major issues were encountered in this fraction of the SDG.

American Radiation Services – SDG: ARS1-15-03096- Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: The SDG aqueous samples were not preserved in the field or at the laboratory with nitric acid per SAP and method requirements. EPA method 901.1 recommends sample preservation be performed at the time of collection by adding enough 1N nitric acid to the samples to bring it to pH 2 or at the laboratory within five days of collection. The lack of sample preservation can lead to sample radionuclides adsorbing to the counting container walls, compromising the homogeneity of the samples. For this reason, the 5 SDG RB water detected and non-detected results for Potassium-40, Radium-226, and Thorium-232 were qualified as estimated (J/UJ). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable

standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for the preparation batch containing the samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample RB-DPT-102815 (ARS1-15-03096-001DUP) for the preparation batch containing the water samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

DUP Sample Prep Batch Isotope Z-score RB-DPT-102815 B15-03783 Potassium-40 0.51 Radium-226 0.03 Thorium-232 0.65

The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. VIII.) Field Duplicate (FD): There were no FD samples identified for this fraction of the SDG. FD samples have been analyzed at the project-specified frequency of 5% of the field samples, so no action was taken. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences:

Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): The following sample isotope detection limits exceeded the project Required Detection Limit (RDL):

The above non-detected sample isotope results for Radium-226 and Thorium-232 were qualified as estimated (UJ) due to sample detection limits exceeding the project required detection limit. The validator questions the usefulness of the Radium-226 data since all of the MDCs are greater than the project action limit (PAL) of 5 pCi/L. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All Radium-226 2σ CSUs were greater than the PAL of 15 pCi/L and were qualified (UJ) for excessive uncertainty. This excessive uncertainty along with the high sample MDCs may impact the usefulness of this data. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section

American Radiation Services – SDG: ARS1-15-03373 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: See major issues section below for rejected data. All other laboratory data were acceptable with qualifications. MAJOR ISSUES I.) Nuclide Identification and Interferences: Note: Thorium-232 is determined via secular equilibrium with its daughter, Actinium-228. The following laboratory reported sample results for Potassium-40 (K-40) were severely biased high due to Actinium-228 (Thorium-232) interference:

Laboratory Interference Laboratory Client Sample Reported K-40 Corrected K-40 Thorium-232 BRICK-12 184.87 pCi/g 14.6 pCi/g 2206 pCi/g CASTIRON-14 215.93 pCi/g 16.8 pCi/g 2536 pCi/g

Due to the high Thorium-232 activities in the above listed samples, the Actinium-228 gamma peak at 1459.3 keV interfered with the 1460.7 keV Potassium-40 peak. The laboratory instrument software did not interference correct for this interference, which caused severely biased high results for Potassium-40. For this reason, the above listed sample results for Potassium-40 were qualified as rejected (R). The Potassium-40 interference corrected results as calculated by the validator were based on the Actinium-228 key-line at 911.07 keV. No other major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times:

1

All Sample Receipt, Preparation and Holding Time criteria were met. No data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for each preparation batch containing the samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed each preparation batch containing the samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample BRICK-12 (ARS1-15-03373-001DUP) for the preparation batch containing 2 samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

DUP Sample Prep Batch Isotope Z-score BRICK-12 B15-03849 Potassium-40 10.3 Radium-226 0.32 Thorium-232 0.21

The Potassium-40 Z-score result was above the |Z| < 1.96 QC limit. The associated Potassium-40 sample results were rejected (see Major Issues section) so no further qualification was necessary. The 2 associated

2

samples were BRICK-12 and CASTIRON-14. Duplicate analyses were performed on SDG sample BRICK-16 (ARS1-15-03373-002DUP) for the preparation batch containing 7 samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

DUP Sample Prep Batch Isotope Z-score BRICK-16 B15-03850 Potassium-40 0.64 Radium-226 1.25 Thorium-232 1.23

The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. VIII.) Field Duplicate (FD): There were no FD samples identified for this fraction of the SDG. FD samples have been analyzed at the project-specified frequency of 5% of the field samples, so no action was taken. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: See Major Issues section above for Potassium-40 rejected data. Radium-226 is reported in these samples from the 3.5% abundant Radium-226 gamma peak at 186.1 keV. The 54% abundant Uranium-235 peak at 185.7 keV is an interference since the gamma detector/software cannot resolve the two peaks. Due to this reason, the detected Radium-226 results are potentially biased high and were qualified as estimated (J). The associated samples were: BRICK-12, BRICK-16, and CASTIRON-14. All other data validation criteria pertaining to Nuclide Identification and Interferences were met. No further action was necessary. XII.) Required Detection Limits (RDLs): The following sample isotope detection limits exceeded the project Required Detection Limit (RDL):

Isotope Client Sample ID Sample MDC Project RDL Radium-226 CONC-14 0.154 pCi/g 0.07 pCi/g

The above non-detected sample isotope results for Radium-226 were qualified as estimated (UJ) due to sample detection limits exceeding the project required detection limit. Samples BRICK-12, BRICK-16, and CASTIRON-14 had MDCs greater than their RDLs but had activities much higher than the RDLs so qualification was not warranted. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required.

EPA method 901.1 recommends sample preservation be performed at the time of collection by adding enough 1N nitric acid to the samples to bring it to pH 2 or at the laboratory within five days of collection. The lack of sample preservation can lead to sample radionuclides adsorbing to the counting container walls, compromising the homogeneity of the samples. For this reason, the 1 SDG RB water results, which were all non-detected, for Potassium-40, Radium-226, and Thorium-232 were qualified as estimated (UJ).

Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.)

The above non-detected sample isotope results for Radium-226 and Thorium-232 were qualified as estimated (UJ) due to sample detection limits exceeding the project required detection limit. The validator questions the usefulness of the Radium-226 data since the MDC is greater than the project action limit (PAL) of 5 pCi/L. XIII.)

American Radiation Services – SDG: ARS1-15-03460 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometry (1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SB-34-04-06 219.64 g 1.5 g/cc 0.878 g/cc 41.4 SB-03-00-02 261.22 g 1.5 g/cc 1.044 g/cc 30.3

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results, which were all detected for the above listed samples, were qualified as estimated (J). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary.

II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for the preparation batch containing the soil samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for the preparation batch containing the soil samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SB-02-00-02 (ARS1-15-03460-011DUP) for the preparation batch containing the 16 soil samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

The Potassium-40 Z-score result was above the |Z| < 1.96 QC limit. The Potassium-40 results, which were both detected, were qualified as estimated (J). The 2 associated samples were SB-50-00-01 and SB-950-00-01. All other Z-score results were within the |Z| < 1.96 QC limit. No further action was needed. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Note: Thorium-232 is determined via secular equilibrium with its daughter, Actinium-228. The following laboratory reported sample results for Potassium-40 (K-40) were biased high due to Actinium-228 (Thorium-232) interference:

Due to the high Thorium-232 activities in the above listed samples, the Actinium-228 gamma peak at 1459.3 keV interfered with the 1460.7 keV Potassium-40 peak. The laboratory instrument software did not interference correct for this interference, which caused biased high results for Potassium-40. For this reason, the above listed sample results for Potassium-40 were qualified as estimated (J). The Potassium-40 interference corrected results were calculated by the validator based on the Actinium-228 key-line at 911.07

keV. All other data validation criteria pertaining to Nuclide Identification and Interferences were met. No further action was necessary. XII.) Required Detection Limits (RDLs): Samples SB-07-14-16, SB-08-14-16, SB-50-00-01, SB-950-00-01, and SB-07-00-02 had Radium-226 and Thorium-232 MDCs greater than their RDLs but had activities much higher than the RDLs so qualification was not warranted. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. SDG sample SB-08-06-08 was transcribed by the laboratory as SB-08-06-06 in the raw data, Form I, and EDD. The validator corrected the transcription error in the EDD. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General: The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses.

II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results. It was noted that the Thorium-229 tracer recoveries were lower than typical, with 2 of the 5 samples being qualified for low tracer recoveries. After evaluating the alpha spectroscopy sample spectra, it was observed that the regions of interests (ROIs) chosen by the instrument software were correct. There may be matrix interferences causing sample attenuation that would explain the lower Thorium-232 results by alpha spec for samples SB-50-00-01 and SB-950-00-01.

Method Blank (MB): One MB was analyzed for each preparation batch associated with this fraction of the SDG. In MB ARS1-B16-00070-03, the Thorium-228 activity of 0.117 pCi/g was above its sample-specific MDC of 0.027 pCi/g. The associated samples had Thorium-228 activities much greater than the MB; therefore, potential blank contamination was not a concern. All other isotope detections were less than their sample-specific MDCs associated with this fraction of the SDG. No action was taken. Equipment Blank: Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for each preparation batch for the soil samples associated with this fraction of the SDG. All LCS criteria were met. No action was required VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SB-34-04-06 (ARS1-15-03460-008DUP) for the preparation batch containing the soil samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. IX.) Matrix Spike (MS): MS sample analysis was not required since the analytical method utilized a tracer to correct for losses during sample preparation. No action was needed. X.) Chemical Yield (Tracer Recovery): The initial isotopic Thorium analysis of the 5 associated SDG samples produced low tracer recoveries. The following Thorium-229 tracer recoveries, despite reanalysis, were below the QC limit of 30%:

Due to the low tracer recoveries for the above listed samples, the Thorium-228/230/232 results, which were all detected, were qualified as estimated (J). Only the RE results were presented in the data package for review and reporting. The validator was in agreement with the reporting. All other Thorium-229 and Uranium-232 Tracer Yield criteria were met. No further qualification was necessary. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): Samples SB-08-14-16 and SB-950-00-01 had Thorium-228/230/232 MDCs greater than their RDLs but had

activities much higher than the RDLs so qualification was not warranted. All other sample isotope detection limits for Thorium-228/230/232 and Uranium-234/235/238 were less than their respective RDLs. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.)

MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample density (d) and/or volume was not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometry (1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SB-33-04-06 235.58 g 1.5 g/cc 0.942 g/cc 37.2

The low sample density and/or volume difference indicates a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results, which were all detected for the above listed sample, were qualified as estimated (J).

Two sets of FD samples were identified for this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the field sampling and laboratory precision for the sample matrix.


The Potassium-40, Radium-226, and Thorium-232 Z-score results were above the |Z| < 1.96 QC limit. The associated Potassium-40, Radium-226, and Thorium-232 sample results, which were all detected, were qualified as estimated (J). The associated sample was Parent sample SB-36-00-02. The FD sample, SB-936-00-02 was analyzed in SDG ARS1- 15-03462. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Note: Thorium-232 is determined via secular equilibrium with its daughter, Actinium-228. The following laboratory reported sample result for Potassium-40 (K-40) was biased high due to Actinium-228 (Thorium-232) interference:

Laboratory Interference Laboratory Client Sample Reported K-40 Corrected K-40 Thorium-232 SB-44-00-02 15.836 pCi/g 12.1 pCi/g 49.243 pCi/g

Due to the high Thorium-232 activity in the above listed sample, the Actinium-228 gamma peak at 1459.3 keV interfered with the 1460.7 keV Potassium-40 peak. The laboratory instrument software did not interference correct for this interference, which caused a biased high result for Potassium-40. For this reason, the above listed sample result for Potassium-40 was qualified as estimated (J). The Potassium-40 interference corrected result was calculated by the validator based on the Actinium-228 key-line at 911.07 keV. All other data validation criteria pertaining to Nuclide Identification and Interferences were met. No further action was necessary. XII.) Required Detection Limits (RDLs): Sample SB-44-00-02 had Radium-226 and Thorium-232 MDCs greater than their RDLs but had activities

much higher than the RDLs so qualification was not warranted. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.)

General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: See major issues section below for rejected data. All other laboratory data were acceptable with qualifications. MAJOR ISSUES I.) Sample Preparation: The following sample density (d) and/or volume was not representative of the calibration standard density (d) and/or volume of the 250 mL Jar geometry (1748-94-41):

The extremely low sample density and/or volume difference indicates a potential severe bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed sample was qualified as rejected (R). No other major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: For the 4 SDG soil samples, Radium-226 is reported from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228.

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples, which were all detected, were qualified as estimated (J). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for each preparation batch containing the samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected.

For the second set of FD samples, the Potassium-40, Radium-226, and Thorium-232 Z-score results were above the |Z| < 1.96 QC limit. The associated Potassium-40, Radium-226, and Thorium-232 sample results, which were all detected, were qualified as estimated (J). The associated sample was FD sample SB-936-00-02. The Parent sample, SB-36-00-02 was analyzed in SDG ARS1- 15-03461 and was qualified as well. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required.

X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: The following laboratory reported sample results for Potassium-40 (K-40) were biased high due to Actinium-228 (Thorium-232) interference:

Laboratory Interference Laboratory Client Sample ID Reported K-40 Corrected K-40 Thorium-232 BRICK-06-LOT44 32.95 pCi/g 0.93 pCi/g 415.2 pCi/g BRICK-09-LOT42 33.47 pCi/g 21.4 pCi/g 152.7 pCi/g CONC-07-LOT42 12.98 pCi/g 8.60 pCi/g 57.64 pCi/g SB-51-00-01 16.04 pCi/g 12.8 pCi/g 43.93 pCi/g

Due to the high Thorium-232 activities in the above listed samples, the Actinium-228 gamma peak at 1459.3 keV interfered with the 1460.7 keV Potassium-40 peak. The laboratory instrument software did not interference correct for this interference, which caused biased high results for Potassium-40. For this reason, the above listed sample results for Potassium-40 were qualified as estimated (J). The Potassium-40 interference corrected results were calculated by the validator based on the Actinium-228 key-line at 911.07 keV. For the non-soil SDG samples, Radium-226 is reported from the 3.5% abundant Radium-226 gamma peak at 186.1 keV. The 54% abundant Uranium-235 peak at 185.7 keV is an interference since the gamma detector/software cannot resolve the two peaks. Due to this reason, the detected Radium-226 results are potentially biased high and were qualified as estimated (J). The associated samples were: BRICK-02-LOT33, BRICK-03-LOT46, BRICK-06-LOT44, BRICK-09-LOT42, BRICK-902-LOT33, CONC-07-LOT42, and CIND-01-LOT33. All other data validation criteria pertaining to Nuclide Identification and Interferences were met. No further action was necessary. XII.) Required Detection Limits (RDLs): The following sample isotope detection limits exceeded the project Required Detection Limit (RDL):

Isotope Client Sample ID Sample MDC Project RDL Radium-226 CONC-08-LOT42 0.705 pCi/g 0.07 pCi/g IBEAM-05-LOT46 0.723 pCi/g 0.07 pCi/g

The above non-detected sample isotope results for Radium-226 were qualified as estimated (UJ) due to sample detection limits exceeding the project required detection limit. Several of the SDG samples had MDCs greater than their RDLs but had activities much higher than the

4

RDLs so qualification was not warranted. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required.

American Radiation Services – SDG: ARS1-16-00120 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample density (d) and/or volume was not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometry (1595-98-4):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SED-12-COATING 152.98 1.5 0.602 59.9

The low sample density and/or volume difference indicates a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples, which were all detected, were qualified as estimated (J). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary.

All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for each preparation batch containing the soil samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample BKSB-904-00-02 (ARS1-16-00120-004DUP) for the preparation batch containing the 16 soil samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Note: Thorium-232 is determined via secular equilibrium with its daughter, Actinium-228. The following laboratory reported sample results for Potassium-40 (K-40) were biased high due to Actinium-228 (Thorium-232) interference:

Due to the high Thorium-232 activities in the above listed samples, the Actinium-228 gamma peak at 1459.3 keV interfered with the 1460.7 keV Potassium-40 peak. The laboratory instrument software did not correct for this interference, which caused biased high results for Potassium-40. For this reason, the above listed sample results for Potassium-40 were qualified as estimated (J). The Potassium-40 interference corrected results were calculated by the validator based on the Actinium-228 key-line at 911.07 keV. All other data validation criteria pertaining to Nuclide Identification and Interferences were met. No further action was necessary. XII.)

The detected sample isotope results for Radium-226 and Thorium-232 did not warrant qualification since the results were several times higher than the MDC. All other sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.)

The results were in fair agreement. No action was needed. MAJOR ISSUES I.) Laboratory Control Sample (LCS): Sample SED-12-COATING was analyzed twice due to low tracer recoveries. On the third analysis attempt in prep batch B16-00445, the lab used a different digestion method which brought the sample tracer recoveries above the QC limit. But the LCS had a severely low tracer recovery of 0.25% and an LCS recovery of 17%. Both the LCS and LCSD were non-detected. The table below shows the LCS/LCSD deficiencies.

Sample SED-12-COATING was reanalyzed in prep batch B16-00445 with acceptable tracer recovery but was rejected due to LCS deficiencies. All other Thorium-229 and Uranium-232 Tracer Yield criteria were met. No qualification was necessary. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary.

American Radiation Services – SDG: ARS1-16-00121 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample densities (d) and/or volumes were not representative of the calibration standard densities (d) and/or volumes of the 90mm Petri Dish geometry (1559-72-1) and 250 ml tuna can geometry (1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SED-12-BOTTOM 20.26 1.5 0.405 73 SB-35-06-08 252.40 1.5 1.010 33

The low sample density and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples, which were all detected, were qualified as estimated (J).

2

All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met. No data qualification was necessary. III.) Calibration: Initial and Verification Calibrations were performed at the required frequency with NIST traceable standards. All Calibration criteria were met. No action was required. IV.) Background Level: Long Background counts were performed at the required frequency. All Background Level criteria were met. No action was required. V.) Blanks: Method Blank (MB): One MB was analyzed for each preparation batch containing the soil samples associated with this fraction of the SDG. All isotope detections were less than their sample-specific MDCs. No action was taken. Equipment Blank (EB): Dedicated sampling equipment was used; therefore, equipment blanks were not collected. No action was needed. VI.) Laboratory Control Sample (LCS): One LCS/LCSD set was analyzed for each preparation batch containing the soil samples associated with this fraction of the SDG. All LCS criteria were met. No action was required. VII.) Laboratory Duplicate (DUP): Duplicate analyses were performed on SDG sample SB-19-00-02 (ARS1-16-00121-001DUP) for the preparation batch containing the 16 samples associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. Sample SED-12-BOTTOM was reanalyzed in prep batch B16-00355 in a different geometry due to an inconsistent Thorium-232 activity relative to the isotopic Thorium-232 result. Duplicate analyses were performed on SDG sample SED-12-BOTTOM (ARS1-16-00121-012DUP) for the preparation batch containing the RE sample associated with this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the laboratory subsampling and overall precision of the sample measurement process for the sample matrix.

The Potassium-40 Z-score result was above the |Z| < 1.96 QC limit. The Potassium-40 result, which was detected, was qualified as estimated (J). The associated sample was SED-12-BOTTOM. The other Z-score results were within the |Z| < 1.96 QC limit. No further action was needed. VIII.) Field Duplicate (FD): One set of FD samples was identified for this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the field sampling and laboratory precision for the sample matrix.


The Z-score results were within the |Z| < 1.96 QC limit. No action was needed. IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Note: Thorium-232 is determined via secular equilibrium with its daughter, Actinium-228. The following laboratory reported sample result for Potassium-40 (K-40) was biased high due to Actinium-228 (Thorium-232) interference:

4

Laboratory Interference Laboratory Client Sample Reported K-40 Corrected K-40 Thorium-232 SED-12-BOTTOM 72.749 pCi/g 44.6 pCi/g 1079.9 pCi/g

Due to the high Thorium-232 activity in the above listed sample, the Actinium-228 gamma peak at 1459.3 keV interfered with the 1460.7 keV Potassium-40 peak. The laboratory instrument software did not correct for this interference, which caused the biased high result for Potassium-40. For this reason, the above listed sample result for Potassium-40 was qualified as estimated (J). The Potassium-40 interference corrected result was calculated by the validator based on the Actinium-228 key-line at 911.07 keV. All other data validation criteria pertaining to Nuclide Identification and Interferences were met. No further action was necessary. XII.) Required Detection Limits (RDLs): The following sample isotope detection limits exceeded the project Required Detection Limits (RDLs):

Isotope Client Sample ID Sample MDC Project RDL Radium-226 SED-12-BOTTOM 4.254 pCi/g 0.7 pCi/g Thorium-232 SED-12-BOTTOM 7.800 pCi/g 1.0 pCi/g

The detected sample isotope results for Radium-226 and Thorium-232 did not warrant qualification since the results were several times higher than the MDC. All other sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed.

XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.) General: The laboratory has cited analytical method DOE A-01-R Modified for the Isotopic Thorium and Isotopic Uranium analyses. II.) Overall Assessment of Data: Please see major issues section below for rejected data. Validator’s Note: The table below compares the Thorium-232 results by gamma spectrometry and by alpha spectrometry with the relative percent differences (RPDs) presented for the results.

With the exception of sample SB-35-06-08, the results were in fair agreement. The validator did not find any definitive reason why the results differed for sample SB-35-06-08. MAJOR ISSUES I.) Laboratory Control Sample (LCS): Sample SED-12-BOTTOM was analyzed twice due to low tracer recoveries. On the third analysis attempt in prep batch B16-00445, the lab used a different digestion method which brought the sample tracer recovery above the QC limit. But the LCS had a severely low tracer recovery of 0.25% and an LCS recovery of 17%. Both the LCS and LCSD were non-detected. The table below shows the LCS/LCSD deficiencies.

The Thorium-228, Thorium-230, and Thorium-232 results were rejected (R) due to severe LCS deficiencies for sample SED-12-BOTTOM. See Major Issues section above. VIII.) Field Duplicate (FD): One set of FD samples was identified for this fraction of the SDG. Below are the calculated Z-scores (normalized absolute differences) used to evaluate the field sampling and laboratory precision for the sample matrix.

The Uranium-234 and Uranium-238 Z-score results were above the |Z| < 1.96 QC limit. The Uranium-234 and Uranium-238 results, which were all detected, were qualified as estimated (J). The associated samples were SB-52-00-01 and SB-952-00-01. The other Z-score results were within the |Z| < 1.96 QC limit. No further action was needed. IX.) Matrix Spike (MS): MS sample analysis was not required since the analytical method utilized a tracer to correct for losses during sample preparation. No action was needed. X.) Chemical Yield (Tracer Recovery): The following tracer recoveries were below the QC limit of 30%:

Client Sample Prep Batch Tracer Recovery SB-52-00-01 B16-00156 Thorium-229 4 % SB-54-00-01 B16-00156 Thorium-229 17 % SB-952-00-01 B16-00156 Thorium-229 5% SED-12-BOTTOM B16-00156 Thorium-229 2% SWSB-03-00-01 B16-00156 Thorium-229 0.09%

Samples SB-52-00-01, SB-952-00-01, and SWSB-03-00-01 were reanalyzed in prep batch B16-00212 with acceptable tracer recoveries; therefore, data qualification was not needed. After reanalysis, sample SB-54-00-01 still had low tracer recovery. The original results were reported. For this reason, the Thorium-228/230/232 results for sample SB-54-00-01, which were all detected, were qualified as estimated (J). Sample SED-12-BOTTOM was reanalyzed in prep batch B16-00445 with acceptable tracer recovery but was rejected due to LCS deficiencies. All other Thorium-229 and Uranium-232 Tracer Yield criteria were met. No qualification was necessary. XI.) Nuclide Identification and Interferences: Sample peak energies were within their expected region of interest (ROI) and were properly identified. There were no interferences observed in the sample spectra and/or peak reports. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): The following sample isotope detection limits exceeded the project Required Detection Limits (RDLs):

Isotope Client Sample ID Sample MDC Project RDL Uranium-235 SB-35-06-08 0.377 pCi/g 0.07 pCi/g SB-52-00-01 0.417 pCi/g 0.07 pCi/g SB-54-001 0.101 pCi/g 0.07 pCi/g SB-952-00-01 0.127 pCi/g 0.07 pCi/g

The above non-detected sample isotope results for Uranium-235 were qualified as estimated (UJ) due to sample detection limits exceeding the project required detection limits. Several Thorium isotopes had MDCs exceeding the RDL but had activities several times greater than their MDCs so qualification was not warranted. All other sample isotope detection limits for Thorium-228/230/232 and Uranium-234/235/238 were less than their respective RDLs. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.)

IX.) Matrix Spike (MS): MS sample analysis is not applicable for Gamma Spectrometry. No data qualification was required. X.) Chemical Yield: No tracers or chemical carriers are employed in Gamma Spectrometry analysis for the isotopes of interest in this SDG. No data qualification was required. XI.) Nuclide Identification and Interferences: Note: Thorium-232 is determined via secular equilibrium with its daughter, Actinium-228. All data validation criteria pertaining to Nuclide Identification and Interferences were met. No action was necessary. XII.) Required Detection Limits (RDLs): All sample isotope detection limits for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required.

V.) Blanks: Method Blank (MB): One MB was analyzed for each preparation batch associated with this fraction of the SDG. In MB ARS1-B16-00268-03, the Thorium-228 activity of 0.128 pCi/g was above its sample-specific MDC of 0.060 pCi/g. The following associated samples that had detections for Thorium-228 were evaluated for potential blank contamination bias:

ZDER was calculated to determine the relative difference of sample isotope results with the failed blank isotope result. The affected detected sample results for Thorium-228 in the associated samples were demonstrated to be significantly different (ZDER > 2.58); therefore, did not require data qualification. All other isotope detections were less than their sample-specific MDCs associated with this fraction of the SDG. No further action was taken.

American Radiation Services – SDG: ARS1-16-00393 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometries (1559-72-6, 1748-90-1):

Client Sample Sample (wt.) Cal Std (d) Sample (d) %D SB-69-04-05 246.30 g 1.5 g/cc 0.985 g/cc 34.3 SB-69-00-02 257.25 g 1.5 g/cc 1.029 g/cc 31.4

The low sample densities and/or volume differences indicate a potential bias for the sample results. For this reason, using professional judgment, the Potassium-40, Radium-226, and Thorium-232 results for the above listed samples, which were all detected, were qualified as estimated (J). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary.

Isotope Client Sample ID Sample MDC Project RDL Thorium-232 SB-65-00-02 1.6 pCi/g 1.0 pCi/g

The detected sample isotope result for Thorium-232 did not warrant qualification since the result was several times higher than the MDC. All other sample isotope detection limits (MDCs) for Radium-226 and Thorium-232 were less than their respective RDLs. An RDL was not assigned for Potassium-40. No data qualification was required. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: There were no negative (absolute) sample results greater than the reported 2σ CSU. No data qualification was required. XV.) Method Uncertainty All sample uncertainties (1σ CSU) for detected sample results near or below the Project Action Level (PAL) met the project requirement maximum relative uncertainty of ≤10% of the isotope-specific PAL. No data qualification was needed. XVI.) Calculation / Transcription Verification: The duplicate DER results reported by the laboratory for the gamma spec analyses differed from the validator’s calculations. It appears that the laboratory used the 2σ CSU in the calculation instead of the 1σ CSU. The validator DER calculated results for the gamma spec duplicate analyses are presented in section VII of this report and were used for the qualification criteria if needed. There were no other discrepancies noted in Calculation / Transcription Verification. No action was required. ALPHA SPECTROMETRY – (Thorium-228/230/232 and Uranium-234/235/238) SUMMARY I.)

American Radiation Services – SDG: ARS1-16-00411 - Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: Note: Radium-226 is reported in these samples from the weighted averages of the daughter progenies, Bismuth-214 and Lead-214. The samples were sealed for a minimum 21-day ingrowth period prior to gamma counting to allow the Bismuth-214 and Lead-214 to reach secular equilibrium with Radon-222 and the parent Radium-226. Thorium-232 (Radium-228) is determined via secular equilibrium with its daughter, Actinium-228. The following sample densities (d) and/or volumes were not representative of the calibration standard density (d) and/or volume of the 250 ml tuna can geometries (1559-72-6, 1595-72-6, 1748-90-1):

American Radiation Services – SDG: ARS1-16-00915- Radiochemistry GAMMA SPECTROMETRY - (Potassium-40, Radium-226, and Thorium-232) SUMMARY I.) General: The laboratory has cited analytical method EPA 901.1 Modified for the Gamma Spectrometry analyses. II.) Overall Assessment of Data: All laboratory data were acceptable with qualifications. MAJOR ISSUES No major issues were encountered in this fraction of the SDG. MINOR ISSUES / COMPLIANT DATA I.) Sample Receipt, Preparation and Holding Times: Sample Preparation: The SDG aqueous samples were not preserved in the field or at the laboratory with nitric acid per SAP and method requirements. EPA method 901.1 recommends sample preservation be performed at the time of collection by adding enough 1N nitric acid to the sample(s) to adjust it to pH 2 or at the laboratory within five days of collection. The lack of sample preservation can lead to sample radionuclides adsorbing to the counting container walls, compromising the homogeneity of the samples. For this reason, the 6 SDG MW ground water detected and non-detected results for Potassium-40, Radium-226, and Thorium-232 were qualified as estimated (J/UJ). All other Sample Receipt, Preparation and Holding Time criteria were met. No further data qualification was necessary. II.) Instrument Performance: Instrument performance checks were performed prior to sample counting for energy, resolution, activity, and background. All Instrument Performance criteria were met.

questions the usefulness of the Radium-226 data since all of the MDCs are greater than the project action limit (PAL) of 5 pCi/L. XIII.) Detection Decisions: All reported sample results that were less than their sample-specific MDC were considered undetected (U). All Detection Decision criteria were met. No data qualification was needed. XIV.) Negative Sample Results: The following negative sample analyte result (absolute) was greater than its reported 2σ CSU:

Client Sample ID Isotope Result 2σ CSU MW-904-R2 Potassium-40 -58.72 46.367

Due to the low biased result, the above listed sample isotope result was qualified as estimated (UJ). All other negative sample results (absolute) were less than their respective 2σ CSUs. No further data qualification was required. XV.) Method Uncertainty All Radium-226 2σ CSUs were greater than the PAL of 5 pCi/L and were qualified (UJ) for excessive uncertainty. This excessive uncertainty along with the high sample MDCs may impact the usefulness of this data. XVI.)
