At present, the waste is placed in three active embankments: (1) Class A West, (2) Mixed Waste, and (3) 11e.(2). The LARW embankment was closed in October 2005 when the final cover was completed. The Class A West embankment design, approved on November 26, 2012, incorporates both the former Class A and Class A North embankments. This report summarizes 2023 groundwater monitoring activities associated with each of these embankments. The facility is licensed and permitted to operate under the following laws and rules: x Radioactive Material License #UT 2300249 to receive, acquire, possess, and transfer byproduct, source, and special nuclear material pursuant to the Atomic Energy Act of 1954, as amended, the Energy Reorganization Act of 1974 (Public Law 93-438), and Title 10, Code of Federal Regulations, Chapter I, Parts 30, 31, 33, 34, 35, 39, 40, and 70. x Radioactive Material License #UT 2300478 to transfer, receive, possess, and use specific radioactive materials pursuant to Section 19-3-104 of the Utah Code annotated 1953 and the Utah Department of Environmental Quality Rules for the control of ionizing radiation. x Groundwater Quality Discharge Permit No. UGW450005 (GWQDP) for Class A Radioactive Waste and 11e.(2) waste disposal facilities, pursuant to the Utah Water Quality Act, Title 19, Chapter 5, Utah Code annotated 1953 as amended. x State-issued Part B Permit (Part B Permit) operated under EPA ID Number UTD982598898 to treat, store, and dispose of Mixed Waste (MW) pursuant to the Utah Solid and Hazardous Waste Act, (the Act), 26-14-1 et. seq., Utah Code Annotated 1953 and the Utah Administrative Code (UAC) (R315) as authorized by the U.S. Environmental Protection Agency (EPA) under Section 3006 (b) of the Resource Conservation and Recovery Act (RCRA). x Coordinated Approval of Mixed Waste Landfill Cell (MWLC) and Waiver of Technical Requirements for Land Disposal of Polychlorinated Biphenyl (PCB) Waste, U.S. EPA, Ref: 8P-P3T. EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 4 1.2 Monitoring EnergySolutions conducted annual [GWQDP Part I.F.5.(c)] and periodic groundwater sampling events in 2023 at compliance monitoring locations associated with the 11e.(2), LARW, Mixed Waste, and Class A West embankments. The periodic events consisted of probable-out-of-compliance (POOC) (GWQDP Part I.G.2) and out-of-compliance (OOC) (GWQDP Part I.G.3) sampling events. Monitoring wells sampled in 2023 are described in Part I, Sections F.1.(a), (b), and (c) of the GWQDP and are listed in Table 1-1, below.

Applicable dates and sampling event descriptions are included on the groundwater sampling sheets provided in Attachment 1. This report is divided into four chapters. Chapter 1 provides this introduction. Chapter 2 gives a discussion of field activities, including groundwater sampling. Chapter 3 provides a summary of the data quality assurance evaluation, and Chapter 4 summarizes the monitoring and analytical results for sampling events (including POOC and OOC sampling). 2.0 FIELD ACTIVITIES 2.1 Groundwater Sampling The annual, POOC, and OOC groundwater sampling events were conducted in accordance with the GWQDP Water Monitoring Quality Assurance Plan (QAP) and standard operating procedure CL-EV-PR-004, Groundwater Monitoring. Annual sampling began March 27 and ended June 15, 2023. The following is an overview of field activities performed at each monitoring location. x Inspection of monitoring well condition; x Measurement of depth to water; x Purging; x Measurement of pH, specific conductivity, temperature, dissolved oxygen, and Eh; x Collection of groundwater samples; and x Completion of groundwater sampling sheets and chain-of-custody/laboratory work request (COC) forms. The condition of each monitoring well, including the pad and protective casing, was inspected as prompted by the checklist included on the groundwater sampling sheet. Inspection items provide information on the need for follow-up actions such as redevelopment or repair. Field analytical equipment was calibrated (for pH, specific conductivity, and Eh) according to the manufacturer’s specifications at the beginning of each day. In addition, mid-day and end-of-day calibration checks were performed. Calibration notes were recorded and maintained in a calibration logbook. A minimum of three well volumes was purged from each well prior to sampling. Field parameters were checked during and following well purging to ensure that the groundwater was representative of formation water. In accordance with the GWQDP EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 6 Water Monitoring QAP, field parameters were considered stable and “representative” when three consecutive readings were within ± 0.1 pH units for pH, ± 3 percent for specific conductivity, and ± 1q Celsius for temperature. Eh and dissolved oxygen readings were also recorded. Samples were collected in the following order: volatile organic compounds (VOCs) (when collected), semi-volatile organic compounds (SVOCs), inorganics, total dissolved solids (TDS), anions, cyanide, metals and cations, and radiological constituents. Not all of these constituents were collected at each well. All samples were collected in appropriate containers and preserved as summarized in Table A-1 provided in Appendix A. When filling VOCs vials, the sample pump discharge rate was reduced to the extent possible to allow gentle filling of the vials without aeration. The VOC sampling flow rate was measured daily, when VOCs samples were collected, and documented on the groundwater sampling sheets included in Attachment 1. Sample labels were filled out using indelible ink with the sample ID, preservative, date, time, and the sampler’s initials (for some containers, the information is written directly on the container). Immediately after filling, sample bottles were placed in an ice chest with ice (except samples for radiological analysis, which do not require temperature preservation). The ice was packaged in double Ziploc£ bags to prevent leakage. Pertinent sample information was recorded on the COC, including the sample ID number, sample location, date and time of sample collection, sample type, number of samples, and analysis request. Sample custody was maintained until delivery to the following Utah- Certified laboratories: Chemtech-Ford Laboratories (CTFL) in Salt Lake City, Utah and Eurofins TestAmerica in Denver, Colorado (TAD) for conventional chemistry analyses; and Eurofins TestAmerica in St. Louis, Missouri (TASL) for radiological analyses. As listed above, sampling activities are documented in the groundwater sampling sheets and COC forms. The groundwater sampling sheet contains pertinent information regarding field conditions at each sampling location, calculated and actual purge volumes, flow rates, field parameter measurements, and the specific samples collected. COC forms indicate the date and time samples were collected, the type of sample, the name of the sampling technician(s), the name of the laboratory to which the samples were sent, and the analytical suite requested. Laboratory analytical reports and COC forms are provided in Attachment 3 as an electronic data deliverable (EDD). Copies of the field data sheets are included as Attachment 1. Analytical results are summarized in Chapter 4.0. EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 7 2.2 Depth to Groundwater Measurement Depth-to-groundwater (DTW) measurements were determined quarterly, and for a subset of wells, DTW measurements were determined monthly. The DTW data are summarized with calculated freshwater equivalents in Appendix B Table B-1. Vertical and horizontal hydraulic gradients provided as Tables B-2 and B-3, respectively, are also provided in Appendix B along with groundwater contour maps generated from the quarterly DTW data. 2.3 Mixed Waste Leachate Monitoring Liquid samples were collected from MW leachate sumps (leachate pipes) 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B, 5A, 5B, 6A, 6B, 7A, 7B, 8A, 8B, 9A, 9B, 10A, and 10B for field parameters, VOCs, polychlorinated biphenyls (PCBs), and radiological analyses using a peristaltic pump. Samples were collected on April 17, 18, 20, and 24, 2023. Arrangements were made to sample leachate pipes prior to removal of leachate by vacuum truck operations. Samples were sent to TAD and TASL for conventional and radiological analysis, respectively. Copies of field data sheets are provided in Attachment 1 and analytical results are summarized in Chapter 4.0. Laboratory analytical reports and COC forms are provided as an EDD in Attachment 3. 2.4 Evaporation Pond Sampling The 1995, 1997, 2000, MW, and NW Ponds were sampled on June 19 and 20, 2023. Liquid samples were collected from these ponds for the parameters listed in Part I.F.13.(c) of the GWQDP. Samples were sent to TAD and TASL for conventional and radiological analysis, respectively. Copies of sampling sheets are provided in Attachment 1, and analytical results are summarized in Chapter 4.0. Laboratory analytical reports and COC forms are provided as an EDD in Attachment 3. 2.5 Collection Lysimeter Sampling EnergySolutions currently maintains twelve collection lysimeters in accordance with the Operation, Maintenance, and Closure Plans for Collection Lysimeters in Appendix C of the GWQDP. During 2023, all inspected collection lysimeter sampling pipes had inadequate liquid volumes for sample collection. EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 8 3.0 DATA QUALITY ASSURANCE EVALUATION SUMMARY The overall quality assurance objective of the groundwater compliance monitoring program is to produce data that will fulfill the Data Quality Objectives (DQOs) of the program, which are summarized in Table B.3-1 of the GWQDP Water Monitoring QAP. For this compliance monitoring program, field and laboratory data quality assurance is evaluated in terms of precision, accuracy, representativeness, comparability, and completeness (the PARCC parameters). A summary of the evaluation of Quality Control (QC) samples in relation to the PARCC parameters is presented in Table B.3-2 of the GWQDP Water Monitoring QAP. Evaluation of data is summarized in terms of each PARCC parameter in the following sections. 3.1 Precision Precision is a measure of the reproducibility of the data. For non-radiological inorganic and organic parameters, precision is calculated as the relative percent difference (RPD) as follows: 100 X 2 D)+ (S | D- S| = RPD Where: S = Sample result D = Duplicate result For field duplicate data, the RPD precision acceptance criterion is defined as a control limit of r 25% for sample values greater than five times the laboratory detection limit (LDL). If the sample data are less than five times the LDL, a control limit of r LDL is used. In accordance with the GWQDP Water Monitoring QAP, RPDs were calculated only for those analytes detected above the LDL in both the environmental sample and the field duplicate sample. For radiological parameters, activity results are reported in picoCuries per liter (pCi/L) and include a counting error term. Precision is assessed by calculating the Relative Error Ratio (RER) using the following equation: y) -(x = RER 22ts Where: x = Sample result y = Duplicate result s = Error term of sample t = Error term of duplicate EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 9 In accordance with the GWQDP Water Monitoring QAP, the field duplicate analytical data acceptance criterion is defined as a control limit of less than three for the RER for data greater than five times the LDL. If the sample values are less than five times the LDL, a control limit of r LDL is used. Groundwater sample field duplicates collected in 2023 are summarized in Table 3-1. The number of samples met the frequency of collection requirement of the GWQDP Water Monitoring QAP. Analytes collected in duplicate include all radiological and non- radiological laboratory parameters listed in GWQDP Part I.F.5.c.2. Although precision for field duplicate samples was assessed and reported in Tables C-1 and C-2, field duplicates are not used to qualify data because there is no guidance for qualifying data based on field duplicate RPDs.

Details for the 2023 sampling event are provided in the laboratory data reports included in Attachment 3. 3.2 Accuracy Accuracy is the degree of agreement of a measurement with an accepted reference or “true” value. Accuracy measures bias in the system. An example of bias is interference caused by naturally occurring concentrations of dissolved constituents in a sample. Accuracy is evaluated by the following equation: 100 X C |B -A | =Recovery Percent Where: A = Concentration of analyte in a spiked sample B = Concentration of analyte in an unspiked sample C = Concentration of spike added Laboratory analytical accuracy is assessed by calculation of recovery for MS and MSD samples, LCS and LCS duplicates, surrogate spike samples, calibration standards, and internal standards. Details for the 2023 sampling event are provided in the laboratory data reports included in Attachment 3. 3.3 Representativeness Representativeness is a qualitative expression evaluating the degree to which data represent actual environmental conditions. Representativeness is assessed by the analysis of method blanks (for all analytes) and trip blanks (when VOCs are analytes), and by the collection and analysis of blind field duplicates. Method and trip blanks are used to identify sources of contamination not associated with environmental samples. Low RPDs and RERs for blind field duplicates indicate that sampling techniques are consistent and resulting data are representative of the environment. Representativeness also is evaluated using holding-time and sample preservation criteria. Holding times and preservation are compared to standard method-specific criteria; all holding times and preservation characteristics within the criteria are considered representative. Holding times and preservation characteristics outside criteria are qualitatively evaluated to determine the effect on sample representativeness. EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 11 As discussed in Section 3.1, RPDs and RERs for blind field duplicate samples are reported in Tables C-1 and C-2. Details for analysis of method blanks and trip blanks included in the 2023 sampling event are given in the laboratory data reports provided in Attachment 3. Holding times and preservation characteristics are also documented in the laboratory data reports provided in Attachment 3. 3.4 Comparability Comparability is a qualitative parameter expressing the confidence with which one data set can be compared to another. Comparability is achieved using standardized methods for sample collection and analysis and the use of standardized units of measurement. As discussed in Section 2.0, sample collection, field data measurement, and associated documentation activities for the 2023 event were conducted in accordance with the GWQDP Water Monitoring QAP and standard operating procedure CL-EV-PR-004, Groundwater Monitoring. As documented in the laboratory data reports provided in Attachment 3, the analytical methods used by laboratories were those approved in the GWQDP Water Monitoring QAP. As shown in Tables C-1 through C-6, standardized units of measure are used for radiological data, non-radiological data, and field parameters. The units are consistent with GWQDP groundwater protection levels (GWPLs), and they are consistent with previous Clive facility sampling events. 3.5 Completeness Completeness is defined as the percentage of valid data relative to the total number of measurements. All locations required by the GWQDP were sampled, and all samples were analyzed for the required parameters during sampling events completed in 2023 (Tables C-1 through C-6). No data were rejected by the laboratory or rejected during data validation. Completeness for the 2023 monitoring event was 100%. Data validation was performed in accordance with the GWQDP Water Monitoring QAP requirements and in accordance with U.S. EPA data validation guidelines listed in the Contract Laboratory Program National Functional Guidelines for Organic Data Review (EPA, 1994a) and the Contract Laboratory Program National Functional Guidelines for Inorganic Data Review (EPA, 1994b). The U.S. EPA data validation guidelines are referenced in the GWQDP Water Monitoring QAP. Data validation worksheets are included in Attachment 2. Valid data, acceptable for their intended use and for meeting the GWQDP requirements, were collected from all required monitoring locations in 2023. EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 12 4.0 MONITORING RESULTS 4.1 Groundwater Elevations Quarterly water-level data were used to prepare fresh water equivalent head potentiometric surface maps, which are provided in Appendix B. The maps for 2023 show a predominant southwest-to-northeast flow direction with persistent localized perturbations or mounds in three overlapping areas. The largest mound, extending from the 11e.(2) footprint north to the Class A West embankment area, has been designated as Mound 1. Mound 1 has subsequently been modified by two other perturbations designated Mound 2 and Mound 3. Mound 2 originates in the area of the Southwest Corner Pond and is observed in monitoring wells GW-19A and PZ-1. Mound 3 is centered on monitoring wells GW-60 and GW-63. Mounds 2 and 3 are the result of focused infiltration, following precipitation events, from portions of the Vitro embankment runoff diversion and retention system. All three mounds are discussed below. Mound 1 Mound 1 started forming in the early to mid-1990s as a result of groundwater recharge from ponding of Vitro embankment runoff in the area of current 11e.(2) operations. The down-gradient portion of this mound is currently located below the southern half of the Class A West embankment producing an area where flow directions transition from north-northwesterly to northeasterly. The initial remediation plan for Mound 1 included construction of a temporary diversion ditch to direct Vitro runoff first to the west between the 11e.(2) embankment and the Class A West Embankment and then south to the Southwest Corner Pond, adjacent to the Tooele County road along the western boundary of the facility. The temporary diversion ditch was subsequently relocated in 2001, diverting Vitro runoff to the current drainage system of the 11e.(2) embankment and allowing runoff to flow south to the drainage ditch (South Ditch) that directs flow west into the Southwest Corner Pond. Mounds 2 and 3 have been superimposed on Mound 1, making delineation of the historical extent of and contributions from Mound 1 not possible. Mound 2 Mound 2 was formed as a result of a series of surface water recharge events in the vicinity of the Southwest Corner Pond that began in the spring of 1999. The Southwest Corner Pond was subsequently retrofitted with an additional high density polyethylene liner and leak detection system. A piezometer, PZ-1, was installed adjacent to the north side of the Southwest Corner Pond as an early warning system and is included in depth- to-water measurements. Relatively rapid water level increases at PZ-1 and GW-19A have been associated with overflows of non-contact water from the Southwest Corner Pond (as designed, through the outlet at the southwest corner) that occur following extreme and/or prolonged precipitation events. EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 13 A downward freshwater vertical gradient persisted during 2023 in the vicinity of well pair GW-19A/GW-19B. EnergySolutions submitted a plan, dated January 14, 2010, to reverse the vertical gradient in this well pair by removing the theoretical volume of water in the mound. Groundwater extraction began at the end of 2009 and continues today. Approximately 2.0 million gallons of groundwater have been removed from extraction wells EW-901 and EW-902 and placed into the Southwest Corner Pond as of the end of 2023. Mound 3 Mound 3 influences groundwater levels upgradient of the historical Mound 1 area. It is the result of recharge, in the vicinity of monitoring wells GW-60 and GW-63, from the relocated Vitro run-off diversion ditch (South Ditch) discussed above. Recharge first became apparent in March 2007 water levels at GW-60. Water levels in GW-60 rise and fall rapidly in response to the presence of water in the South Ditch lift station and subsequent removal of the water from the lift station. Water levels in GW-63 respond to infiltration of water from the South Ditch, but the response is more muted relative to that of GW-60. As proposed in submittal CD19-0218 (October 22, 2019), EnergySolutions upgraded the pump capacity at the South Ditch lift station to more efficiently move water from the lift station to the Southwest Corner Pond. A trailer-mounted pump rated at 750 gallons per minute (maximum) was installed at the lift station and connected to a 6-inch diameter line that discharges non-contact storm water at the Southwest Corner Pond inlet. This upgrade, operational in March 2020, has reduced infiltration contributing to Mound 3. Monthly Groundwater Elevation Measurement In accordance with GWQDP Part I.F.5.a, the groundwater elevations of wells GW-19A, GW-19B, GW-60, GW-63, and PZ-1 were measured monthly during 2023 to monitor the status of the groundwater mounds discussed above. The groundwater elevations of wells GW-27 and GW-27D were also measured monthly due to the presence of a downward vertical gradient throughout 2023 (see below). In addition, in accordance with GWQDP Part I.F.5.a, the frequency of water-level monitoring is increased from quarterly to monthly at wells where the quarter-to-quarter elevation measurement changes by greater than 0.4 feet. Based on this requirement, groundwater elevation was measured monthly as shown at the following monitoring wells: x Throughout 2023 – well P3-95 SWC x March to December 2023 – wells GW-24, GW-29, GW-92, and GW-93 x July to December 2023 – wells GW-28, GW-36, GW-37, GW-38R, GW-57, GW-58, GW-88, GW-99, GW-100, GW-103, GW-106, GW-107, GW-108, GW-109, GW-110, GW-111, and GW-129 x July to September 2023 – wells GW-89 and I-1-30 x July and August 2023 – well GW-56R. EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 14 In accordance with a modification of GWQDP Part 1.F.5.a approved by the Director of DWMRC on March 28, 2023 (DRC-2023-001933), EnergySolutions provided notice well GW-56R returned to quarterly groundwater elevation monitoring on August 21, 2023 (CD-2023-165). Similarly, EnergySolutions provided notice wells I-1-30 and GW-89 returned to quarterly groundwater elevation monitoring on September 25, 2023 (CD-2023-188). Groundwater Elevation Summary Except for areas affected by mounding, the groundwater flow direction is predominantly to the northeast beneath Section 32. Figures 1 through 4 provided in Appendix B are the quarterly potentiometric surface maps for 2023. These figures show a general increase in groundwater elevation on the west side of the facility during the first half of 2023 due to infiltration of non-contact water associated with above-average precipitation in winter 2023. The increase is particularly apparent in areas of mounding. During the second half of 2023, groundwater elevations dropped at wells nearest to the sources infiltration in Mounds 2 and 3. Monthly and quarterly groundwater elevations were used to calculate vertical gradients, and quarterly groundwater elevations were used to calculate horizontal gradients. Vertical and horizontal gradients are provided in Appendix B Tables B-2 and B-3, respectively. The spreadsheets used to perform these calculations are included as electronic data files. Upward freshwater vertical gradients were observed at all Clive facility well pairs in 2023 except for GW-19A/19B and GW-27/27D (Table B-2). Groundwater elevations in both well pairs were measured monthly in 2023, and a downward gradient was observed at both pairs throughout the year. The GW-19A/19B well pair is located within the area affected by surface water infiltration and mounding as discussed in the “Mound 2” section above. The GW-27/27D well pair is located near the southwest corner of the Class A West embankment (See Appendix B Figures 1 through 4). The downward freshwater vertical gradient at well pair GW-19A/19B ranged from 0.0330 to 0.1778 ft/ft during 2023, and the downward vertical gradient at GW-27/27D ranged from 0.0047 to 0.0175 ft/ft during 2023 (Table B-2). Monthly monitoring of these well pairs will continue in 2024. Average freshwater horizontal gradients for 2023 did not exceed the gradient limits listed in Part I.H.2.(d) of the GWQDP except in the area of the LARW embankment. As indicated in Table B-3 of Appendix B, the average horizontal gradient in the LARW cell area exceeded the limit of 9.67 x 10-4 ft/ft for all four quarters of 2023. On May 29, 2012 (CD12-0123) EnergySolutions submitted an updated LARW cell infiltration and transport model to the Division of Radiation Control (DRC) to support a larger horizontal gradient limit. None of the LARW average monthly freshwater horizontal gradients observed in 2023 exceed the updated-model gradient limit of 2.70 x 10-3 ft/ft. EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 15 4.2 Monitoring Well Analytical Results Analytical results for the 2023 annual 11e.(2), LARW, and Class A West monitoring well sampling events are provided in Appendix C Tables C-1 and C-2. Data from additional sampling events including monthly OOC, quarterly POOC, and annual MW sampling (radiological results only) are also provided. Table C-1 summarizes field parameter measurements and conventional chemistry results. Radiological results are summarized in Table C-2. GWPL information from Table 1A through 1F of the GWQDP is also provided for each monitoring well in Tables C-1 and C-2 for reference. Accelerated groundwater monitoring results for the first half of 2023 (January to June 2023) were reported to DWMRC on September 8, 2023 (CD-2023-176) in compliance with Part I.H.1.(b) of the GWQDP. This annual report provides the groundwater sampling sheets, data validation worksheets, and analytical laboratory reports for all groundwater samples, including accelerated samples, collected and analyzed during 2023. 4.3 Exceedances A brief discussion of wells in accelerated monitoring status during 2023 follows. Ra-226+Ra-228 (Sum of Radiums) Given the universal GWPL for the sum of radiums, radium-226 (Ra-226) and radium-228 (Ra-228) are less than optimal groundwater monitoring parameters at the Clive Facility. The universal GWPL for the sum of radiums, 5 pCi/L, is a drinking water Maximum Contaminant Level. Clive Facility groundwater is naturally non-potable with high concentrations of dissolved solids due to its occurrence in saline lake-bed sediments. Background concentrations of the sum of radiums in Facility groundwater commonly exceed the 5 pCi/L universal GWPL as documented by the approval of background-based GWPLs exceptions for 20 compliance monitoring wells. In addition, interferences caused by the analysis of naturally high-concentration water influence the reporting of groundwater isotopic radium data, often leading to elevated detection levels and a corresponding reduction in precision. The Facility-specific distribution coefficient for radium is 10 liters per kilogram (L/kg) (Whetstone, 2011). The Facility-specific distribution coefficient for other monitored parameters present in the disposed inventory includes: uranium isotopes (6 L/kg), technetium-99 (0.11 L/kg), and strontium-90 (0.05 L/kg). Tritiated water is not retarded during transport. Sum of radium exceedances in Clive Facility groundwater are not preceded or accompanied by exceedances of other monitored parameters and are not accompanied by changes in groundwater quality indicative of a release from a waste disposal embankment. This includes no observed change in the highly sensitive background ratio of uranium-234 (U-234) to uranium-238 (U-238). For these reasons, EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 16 EnergySolutions considers sum of radium exceedances to be false positives for the presence of contamination. The exceedances are related to variations in background concentrations, potentially influenced by analytical factors. GW-64 and GW-89 – On September 30, 2022 (CD-2022-169), EnergySolutions submitted a request to return compliance monitoring wells GW-64 and GW-89 to in- compliance status (CD-2022-169). Both wells had been in POOC status for the sum of radiums, i.e., sum of the concentrations of Ra-226 and Ra-228. DWMRC approved the status change on January 5, 2023 (DRC-2022-024130), returning wells GW-64 and GW-89 to in-compliance status and ending accelerated monitoring of both wells. Both wells were sampled for Ra-226 and Ra-228 in 2023 during the annual monitoring event and did not exceed the sum of radiums GWPL (Table C-2). GW-77 – On November 20, 2019 (CD19-0234), EnergySolutions notified DWMRC that well GW-77 entered POOC status for the sum of radiums. The annual and quarterly samples collected from GW-77 in 2023 did not exceed the GWPL. The last exceedance occurred in the duplicate sample collected the first quarter of 2022 (Table C-2). As stated in submittal CD19-0234, the sum of radiums exceedances represent natural concentration fluctuations rather than a trend related to contamination. As discussed above, analytical considerations, e.g., matrix interference from high concentrations of dissolved solids, may also be a potential factor in reported Ra-226 and Ra-228 data. In accordance with the requirement to establish a GWPL exception based on the Background Concentration (GWQDP Part I.C, Table 1B, Footnote 1), on October 7, 2022, EnergySolutions requested to modify the well GW-77 sum of radiums GWPL and to return the well to in-compliance monitoring status (CD-2022-175). In accordance with GWQDP Part I.C.4, the request to modify the GWPL was made after submittal of additional groundwater quality data. DWMRC has not yet approved this request. GW-126 – On November 30, 2022 (CD-2022-198), EnergySolutions notified DWMRC that well GW-126 entered POOC status for the sum of radiums. The first quarterly POOC sample was collected from well GW-126 during fourth quarter 2022. During 2023, the third quarter sample and its duplicate exceeded the GWPL (Table C-2). Quarterly sampling will continue in 2024. As stated in submittal CD-2022-198, EnergySolutions believes the well GW-126 exceedance represents natural concentration fluctuations possibly influenced by analytical factors (see discussion above). EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 17 Total Uranium P3-95 SWC – Monitoring well P3-95 SWC has remained in OOC status for total uranium since October 2013. During 2023, total uranium groundwater concentrations at well P3-95 SWC exceeded the total uranium GWPL of 0.180 milligrams per liter (mg/L) from February through May. Based on its conceptual model of the source and transport, EnergySolutions believes the exceedances are related to storm water infiltration from a period of above-average precipitation occurring from late December 2022 through the end of March 2023. During that period, the Clive Facility received 232% of the 30-year average precipitation amount listed in the 2022 annual meteorological summary report (Trinity Consultants, 2023). Total uranium concentrations returned to less than the GWPL from June through the end of 2023 (Table C-2). In response to the 2023 exceedances, EnergySolutions submitted a plan to DWMRC to return well P3-95 SWC to in-compliance status (submittal CD-2023-204; October 9, 2023). The plan includes resumption of groundwater extraction if above-GWPL concentrations return, conducting tracer dye testing to delineate the source of infiltration suspected of transporting uranium to the well, and control of infiltration to reduce/eliminate contaminant transport. DWMRC has not yet provided comment or approved this plan. Groundwater extraction has been effective in returning total uranium concentrations at well P3-95 SWC to less than the GWPL. As of mid-May 2022, when the most-recent extraction event was terminated, approximately 29,670 gallons of groundwater had been extracted from the well since the initiation of most-recent extraction event in June 2019. Operational experience shows total uranium concentrations rapidly decrease and remain below the GWPL during groundwater extraction at well P3-95 SWC. With DWMRC’s approval, EnergySolutions has managed storm water in the north-south ditch near well P3-95 SWC as Priority 1 since December 14, 2016. The temporary variance allows EnergySolutions to remove standing surface water from the ditch immediately following precipitation events. Focused infiltration of surface water from the ditch may be the source of water transporting residual uranium contamination from the shallow subsurface to well P3-95 SWC. On September 22, 2023, DWMRC approved an extension of the temporary storm water management variance until September 22, 2026 (DRC-2023-071888). For 2023, EnergySolutions provided DWMRC with details of accelerated monitoring and corrective action for well P3-95 SWC in quarterly status reports (CD-2023-110, CD-2023-168, CD-2023-233, and CD-2024-035). EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 18 GW-23 – In accordance with Part I.G.2 of the GWQDP, on August 9, 2023, EnergySolutions provided notice that well GW-23 entered POOC status for total uranium (CD-2023-159). The total uranium concentration of the 2023 annual monitoring sample (0.037) exceeded the GWPL of 0.03 pCi/L. Subsequent quarterly POOC samples collected in August and November 2023 did not exceed the GWPL (Table C-2). Quarterly sampling will continue in 2024. EnergySolutions believes the total uranium exceedance at well GW-23 was caused by variability of the natural concentration of uranium, possibly related to infiltration and groundwater mounding occurring west of the well location. Depth-to-water measurements collected during the first half of 2023 indicate mounding occurred west of well GW-23 in response to drainage of non-contact water from the offset on the south side of the Class A West embankment. Despite the concentration increase, the U-234 to U-238 isotopic ratio of the 2023 annual sample and subsequent POOC samples remains consistent with the Clive Facility background ratio. Uranium-234 and Uranium-238 P3-95 SWC – U-234 and U-238 concentrations in well P3-95 SWC groundwater are correlated with the total uranium concentration. During 2023, U-234 concentrations in groundwater at well P3-95 SWC exceeded the GWPL of 48 pCi/L only in the OOC sample collected in February. U-238 concentrations exceeded the GWPL of 79 pCi/L in the February and March OOC samples (Table C-2). Refer to the discussion of total uranium in well P3-95 SWC immediately above for additional information. 4.4 2023 Groundwater Quality Discharge Permit Compliance Status As of the end of 2023, the following monitoring wells are in accelerated monitoring status: x GW-23 – POOC status for total uranium x GW-77 – POOC status for Ra-226+Ra-228 (request to return to in-compliance status submitted October 7, 2022). x GW-126 – POOC status for Ra-226+Ra-228 x P3-95 SWC – OOC status for total uranium, U-234, and U-238 (plan to return to in-compliance status submitted October 9, 2023). As discussed in submittal CD-2022-198 (November 30, 2022) for well GW-126 and submittal CD19-0234 (November 20, 2019) for well GW-77, sum of radiums concentration exceedances observed in groundwater samples reflect fluctuations in naturally occurring radium concentrations. Similarly, as discussed in submittal CD-2023-159 (August 9, 2023) for GW-23, total uranium exceedances are caused by variability of the natural concentration of uranium in groundwater at the well. As EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 19 discussed in submittal CD-2023-204 (October 9, 2023), uranium exceedances at well P3-95 SWC are associated with residual contamination in the shallow subsurface in the vicinity of the well and do not represent release of licensed material from any of the disposal embankments. 4.5 Mixed Waste Leachate Analytical Results In accordance with Part I.H.15 of the GWQDP, results for MW leachate samples are provided in Appendix C Tables C-3 and C-4. Field data sheets, data validation forms, and laboratory data packages are provided in Attachments 1, 2, and 3, respectively. 4.6 Evaporation Pond Analytical Results and Volumes Sampling and analytical results for evaporation ponds are provided in Appendix C Tables C-5 and C-6, in accordance with Part I.H.12.(a) of the GWQDP. Field data sheets, data validation forms, and laboratory data packages are provided in Attachments 1, 2, and 3, respectively. Evaporation pond volumes are summarized in Table 4-1. Table 4-1 provides the sampling date, 2-foot freeboard pond capacity, estimated fullness, and approximate volume in gallons at the time of sampling for each pond. The pond volumes are calculated by first visually estimating the fullness of a pond (i.e., full, ½ full, etc.) and then converting to volume. The conversion is performed using the 2-foot freeboard pond capacities provided to DRC in a submission dated February 1, 2006 and the September 6, 2007 GWQDP Statement of Basis.

EnergySolutions Utah Division of Water Quality 2023 Annual Groundwater February 26, 2024 Monitoring Report 20 4.7 Collection Lysimeter Analytical Results Collection lysimeters were routinely monitored throughout 2023 for free liquids in accordance with Appendix C of the GWQDP. As discussed in Section 2.5, no free liquids were detected in any collection lysimeter during 2023 monitoring, and therefore, no samples were collected. 4.8 Report Summary This report fulfills the GWQDP Part I.H.3 documentation requirements for routine annual monitoring of groundwater, MW leachate, evaporation ponds, and collection lysimeters performed in 2023. Monthly and quarterly groundwater elevation data and quarterly groundwater elevation contour maps are provided. Field forms, laboratory analytical data packages, and data validation worksheets for 2023 sampling activities are included. Liquid volume estimates from evaporation pond monitoring are also reported. In accordance with GWQDP Part I.H.1.b, this report also provides results for accelerated monitoring samples collected during the second half of 2023. Quarterly water level measurements were utilized in determining hydrogeologic properties including: vertical and horizontal groundwater gradients, contouring of the piezometric surface, and the groundwater flow direction in the shallow water-bearing unit. Groundwater mounding is present in the shallow unit beneath the 11e.(2) embankment footprint and downgradient of the South Ditch. The mounding is caused by infiltration of uncontaminated surface water from snowmelt and precipitation events. All samples required to demonstrate compliance with the GWQDP during 2023 were collected and analyzed for all required parameters. All results are valid, and as such, EnergySolutions met the GWQDP Water Monitoring QAP completeness requirement.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 3 coolers at receipt time were 14.2º C, 14.5º C and 14.5º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gamma prep batch 608476 Many isotopes requested for analysis do not have any gamma emissions, or the gamma emissions they do have are very poor. Often, such analytes are reported by gamma spectrometry assuming secular equilibrium with a longer-lived parent. The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 Isotopic Thorium batch 609148 A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing).GW-77 (160-49672-1), GW-64 (160-49672-2), GW-223 (160-49672-3), GW-56R (160-49672-4), GW-16R (160-49672-5), (LCS 160-609148/2-A), (MB 160-609148/1-A) and (160-49672-C-1-D DU) No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 6 coolers at receipt time were 12.9º C, 13.5º C, 14.1º C, 14.1º C, 14.5º C and 14.6º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gamma prep batch 608476 Many isotopes requested for analysis do not have any gamma emissions, or the gamma emissions they do have are very poor. Often, such analytes are reported by gamma spectrometry assuming secular equilibrium with a longer-lived parent. The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 Isotopic Thorium batch 609148 The detection goal was not met for the following sample. Samples was prepped at a reduced volume due to the presence of matrix interference as noted in prep: GW-323 (160-49673-5). Analytical results are reported with the detection limit achieved. A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing).I-1-30 (160-49673-1), GW-66R (160-49673-2), GW-136 (160-49673-3), GW-134 (160-49673-4), GW-323 (160-49673-5), GW-135 (160-49673-6), GW-133 (160-49673-7), GW-132 (160-49673-8), GW-131 (160-49673-9), GW-130 (160-49673-10), (LCS 160-609148/2-A), (MB 160-609148/1-A), (160-49672-C-1-C) and (160-49672-C-1-D DU) No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 3 coolers at receipt time were 17.3º C, 17.7º C and 18.0º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gamma Prep batch 612461 The detection goal of 20 pCi/L was not met for Cs-137 for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This is due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 is well below the RL and MDC. GW-105 (160-49938-4) and (MB 160-612461/1-A) Many isotopes requested for analysis do not have any gamma emissions, or the gamma emissions they do have are very poor. Often, such analytes are reported by gamma spectrometry assuming secular equilibrium with a longer-lived parent. The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 Isotopic Neptunium Prep batch 614174 The tracer recovery is outside the upper control limit (110%) for the following samples due to matrix interferences. The samples and QC have been truncated to 100% to reduce any potential bias a high carrier recovery may have. The data have been qualified and reported.

Sample was prepped at a reduced volume due to the presence of matrix interferences: GW-523 (160-49938-3). Analytical results are reported with the detection limit achieved. A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing).GW-103 (160-49938-1), GW-104 (160-49938-2), GW-523 (160-49938-3), GW-105 (160-49938-4), P3-95 SWC (160-49938-5), (LCS 160-614192/2-A), (MB 160-614192/1-A) and (160-49938-B-3-F DU) The following samples were prepared at a reduced aliquot due to high salt matrix: GW-103 (160-49938-1), GW-104 (160-49938-2), GW-523 (160-49938-3), GW-105 (160-49938-4), P3-95 SWC (160-49938-5) and (160-49938-B-3 DU).

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 6 coolers at receipt time were 17.3º C, 17.7º C, 17.7º C, 18.4º C, 20.3º C and 20.5º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gamma prep batch 612461 The detection goal of 20 pCi/L was not met for Cs-137 for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This is due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 is well below the RL and MDC. 1B (160-49939-1), 4B (160-49939-4), 8B (160-49939-8), 9B (160-49939-9) and (MB 160-612461/1-A) Many isotopes requested for analysis do not have any gamma emissions, or the gamma emissions they do have are very poor. Often, such analytes are reported by gamma spectrometry assuming secular equilibrium with a longer-lived parent. The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 Radium-226 batch 612291 The detection goal was not met for the following samples.

A laboratory control sample/ laboratory control sample duplicate (LCS/LCSD) were prepared instead of a sample duplicate (DUP) to demonstrate batch precision. Isotopic Neptunium batch 614174 The tracer recovery is outside the upper control limit (110%) for the following sample(s) due to matrix interferences. The samples and QC have been truncated to 100% to reduce any potential bias a high carrier recovery may have. The data have been qualified and reported. 1B (160-49939-1), 2B (160-49939-2), 3B (160-49939-3), 4B (160-49939-4), 5B (160-49939-5), 6B (160-49939-6), 7B (160-49939-7), 8B (160-49939-8), 9B (160-49939-9), 10B (160-49939-10), (LCS 160-614174/2-A), (MB 160-614174/1-A), (160-49938-B-3-C) and (160-49938-B-3-D DU).

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 7 coolers at receipt time were 19.5º C, 19.6º C, 19.7º C, 20.0º C, 20.0º C, 20.1º C and 20.4º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gross Beta batch 615480 The detection goal was not met for the following samples due to a reduction of the sample size attributed to high residual mass: 10A (160-50071-5), 1A (160-50071-6), 2A (160-50071-7), 4A (160-50071-9) and 5A (160-50071-10). Analytical results are reported with the detection limit achieved. Gamma 160-613453 Many isotopes requested for analysis do not have any gamma emissions, or the gamma emissions they do have are very poor. Often, such analytes are reported by gamma spectrometry assuming secular equilibrium with a longer-lived parent. The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 The minimum detectable concentration (MDC) for the method blank (MB) is above the requested limit for K40 and Cs137. The activity was not observed in the MB above the MDC or reporting limit (RL). The data for the following sample have been reported with the MDC achieved: (MB 160-613453/1-A) The detection goal of 20 pCi/L for Cs137 was not met for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This may be due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 activity is well below the RL and MDC. 7A (160-50071-2), 8A (160-50071-3), 9A (160-50071-4), 1A (160-50071-6), 2A (160-50071-7) and 3A (160-50071-8) Eurofins St. Louis Page 4 of 53 6/29/2023 1 2 3 4 5 6 7 8 9 10 11 12 Case Narrative Client: Energy Solutions, LLC Job ID: 160-50071-1 Project/Site: RCRA LEACHATE Job ID: 160-50071-1 (Continued) Laboratory: Eurofins St. Louis (Continued) Radium-226 batch 614050 The sample duplicate (DUP) precision was outside control limits. Sample matrix interference is suspected. Samples were prepped at a dilution due to high salt content. (160-50073-B-1-K DU) Isotopic Plutonium Batch 614883 The Np-237 laboratory control sample/laboratory control sample duplicate (LCS/LCSD) recovery (126%) associated with the following sample(s) is outside the upper QC limit of (75-125%) indicating a potential positive bias for that analyte. This analyte was not observed above the MDC/RL in the associated samples; therefore the sample data is not adversely affected by this excursion. The data have been reported with this narrative. (LCS 160-614883/2-A) Isotopic Thorium batch 615049 A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing). The detection goal was not met for the following sample(s). Samples were prepped at a reduced volume due to the presence of matrix interferences: 1A (160-50071-6), 3A (160-50071-8) and 4A (160-50071-9). Analytical results are reported with the detection limit achieved. Isotopic Uranium batch 615050 The detection goal was not met for the following sample(s). Samples were prepped at a reduced volume due to the presence of matrix interferences: 8A (160-50071-3), 1A (160-50071-6) and 3A (160-50071-8). Analytical results are reported with the detection limit achieved. Strontium-90 batch 613855 The following sample had Sr carrier recovery below the 30% QC limit: 2A (160-50071-7) and 3A (160-50071-8). The detection limit was achieved, so the laboratory does not believe this excursion adversely affects the data. Therefore, the data have been reported with this narrative. Iodine 616085 The Laboratory Control Sample (LCS) recovered at 69%. The limits in our LIMS system at 75%-125%reflect the requirements of a regulatory agency that represents a large amount of our work. However, the associated samples are not from this agency and are therefore held to our in-house statistical limits of 50%-132%per method requirements. The LCS is within criteria and no further action is required. The following sample did not meet the requested limit (RL) due to a reduced sample volume, which can be attributed to the presence of matrix interferences noted during the initial preparation: 3A (160-50071-8). The data have been reported with this narrative. The Laboratory Control Sample (LCS) recovered at 69%. The limits in our LIMS system at 75%-125% reflect the requirements of a regulatory agency that represents a large amount of our work. However, the associated samples are not from this agency and are therefore held to our in-house statistical limits of 50%-132%per method requirements. The LCS is within criteria and no further action is required. The following sample carrier recovery was above the limit of 110% (240%); the sample was re-extracted and had similar results and is believed to be attributed to the presence of matrix interferences noted during the initial sample preparation: 10A (160-50071-5). The original data has been truncated to 100% to reduce any potential bias to the result, and is reported with this narrative. Technetium 616545 The Rhenium carrier recovery was outside the upper control limit of 110% (117%) for sample 50071-6 1A (160-50071-6). The Laboratory Control Sample (LCS) have acceptable spike recoveries, demonstrating proper method and instrument performance. The sample carrier recovery for the whole batch has been truncated to 100% to minimize any potential bias a high carrier recovery may have on the results. The detection goal was not met for the following sample due to a shortened count time, which can be attributed to high activity: 8A (160-50071-3). Analytical results are reported with the detection limit achieved. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Unless otherwise noted below, the samples arrived in good condition. The temperature of the cooler at receipt was 19.8º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gamma Prep Batch 160-613453 Many isotopes requested for analysis do not have any gamma emissions, or the gamma emissions they do have are very poor. Often, such analytes are reported by gamma spectrometry assuming secular equilibrium with a longer-lived parent. The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 Radium-226 batch 614050 The sample duplicate (DUP) precision was outside control limits. Sample matrix interference is suspected. Samples were prepped at a dilution due to high salt content. (160-50073-B-1-K DU) Isotopic Thorium batch 614886 A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing). No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 3 coolers at receipt time were 19.8º C, 20.1º C and 20.8º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gamma Prep Batch 613453: The minimum detectable concentration (MDC) for the method blank (MB) is above the requested limit for K40 and Cs137. The activity was not observed in the MB above the MDC or reporting limit (RL). The data for the following sample have been reported with the MDC achieved: (MB 160-613453/1-A) The detection goal of 20 pCi/L for Cs137 was not met for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This may be due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 activity is well below the RL and MDC. GW-137 (160-50073-2) The Minimum Detectable Concentration (MDC) achieved for K40 for the following samples is greater than 250 pCi/L: GW-137 (160-50073-2) and GW-138 (160-50073-3). Activity for K40 is greater than the MDC. Many isotopes requested for analysis do not have any gamma emissions, or the gamma emissions they do have are very poor. Often, such analytes are reported by gamma spectrometry assuming secular equilibrium with a longer-lived parent. The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 Radium-226 Prep Batch 614050: Eurofins St. Louis Page 4 of 38 6/27/2023 1 2 3 4 5 6 7 8 9 10 11 12 Case Narrative Client: Energy Solutions, LLC Job ID: 160-50073-1 Project/Site: ANNUAL LARW Job ID: 160-50073-1 (Continued) Laboratory: Eurofins St. Louis (Continued) The sample duplicate (DUP) precision was outside control limits. Sample matrix interference is suspected. Samples were prepped at a dilution due to high salt content. (160-50073-B-1-K DU) Isotopic Thorium Prep Batch 615049: The detection goal was not met for the following sample(s). Samples were prepped at a reduced volume due to the presence of matrix interferences: GW-138 (160-50073-3) and GW-139 (160-50073-4). Analytical results are reported with the detection limit achieved. A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing). The following samples were prepared at a reduced aliquot due to matrix high in salts: GW-93 (160-50073-1), GW-137 (160-50073-2), GW-138 (160-50073-3), GW-139 (160-50073-4) and GW-22 (160-50073-5). Uranium Prep Batch 160-615050: The following samples were prepared at a reduced aliquot due to matrix high in salts: GW-93 (160-50073-1), GW-137 (160-50073-2), GW-138 (160-50073-3), GW-139 (160-50073-4) and GW-22 (160-50073-5). Isotopic Plutonium Batch 614883 The Np-237 laboratory control sample/laboratory control sample duplicate (LCS/LCSD) recovery (126%) associated with the following sample(s) is outside the upper QC limit of (75-125%) indicating a potential positive bias for that analyte. This analyte was not observed above the MDC/RL in the associated samples; therefore the sample data is not adversely affected by this excursion. The data have been reported with this narrative. (LCS 160-614883/2-A) The following samples were prepared at a reduced aliquot due to matrix high in salts: GW-93 (160-50073-1), GW-137 (160-50073-2), GW-138 (160-50073-3), GW-139 (160-50073-4) and GW-22 (160-50073-5). Strontium-90 Prep Batch 613855: The following sample had Sr carrier recovery below the 30% QC limit: GW-138 (160-50073-3). The detection limit was achieved, so the laboratory does not believe this excursion adversely affects the data. Therefore, the data have been reported with this narrative. Iodine-129 Prep Batch 616085: The Laboratory Control Sample (LCS) recovered at 69%. The limits in our LIMS system at 75%-125%reflect the requirements of a regulatory agency that represents a large amount of our work. However, the associated samples are not from this agency and are therefore held to our in-house statistical limits of 50%-132%per method requirements. The LCS is within criteria and no further action is required. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

In addition, all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Eurofins TestAmerica attests to the validity of the laboratory data generated by Eurofins TestAmerica facilities reported herein. All analyses performed by Eurofins TestAmerica facilities were done using established laboratory SOPs that incorporate QA/QC procedures described in the application methods. Eurofins TestAmerica’s operations groups have reviewed the data for compliance with the laboratory QA/QC plan, and data have been found to be compliant with laboratory protocols unless otherwise noted below. The test results in this report meet all NELAP requirements for parameters for which accreditation is required or available. Any exceptions to NELAP requirements are noted in this report. Pursuant to NELAP, this report may not be reproduced, except in full, without the written approval of the laboratory. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. The matrix for the Method Blank and LCS/LCSD is as close to the samples as can be reasonably achieved. Detailed information can be found in the most current revision of the associated SOP. The method blank (MB) z-score is within limits, unless stated otherwise below, and is stored in the level IV raw data. Manual integrations/ROIs were performed only when necessary and are in compliance with the laboratory’s standard operating procedure. Detailed information can be found in the raw data section of the level IV report. Reference the chain of custody and condition upon receipt report for any variations on receipt conditions and temperature of samples on receipt. This laboratory report is confidential and is intended for the sole use of Eurofins TestAmerica and its client. RECEIPT The samples were received on 6/6/2023 9:00 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 9 coolers at receipt time were 22.7º C, 22.9º C, 22.9º C, 23.0º C, 23.1º C, 23.2º C, 23.2º C, 23.4º C and 23.7º C.

The samples were prepared on 06/26/2023 and analyzed on 07/11/2023. The detection goal was not met for the following sample due to a reduction of the sample size attributed to high residual mass: GW-99 (160-50241-13). Analytical results are reported with the detection limit achieved. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

The samples were prepared on 06/08/2023 and analyzed on 06/15/2023, 06/20/2023 and 06/21/2023. Many isotopes requested for analysis do not have any gamma emissions, or the gamma emissions they do have are very poor. Often, such analytes are reported by gamma spectrometry assuming secular equilibrium with a longer-lived parent. The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 The detection goal for K40 was not met for the following sample(s). GW-26 (160-50241-11). Analytical results are reported with the detection limit achieved. The detection goal of 20 pCi/L was not met for Cs-137 for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This is due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 is well below the RL and MDC.

The samples were prepared on 06/27/2023 and 06/29/2023 and analyzed on 07/01/2023. The Laboratory Control Sample (LCS) recovered at 71%. The limits in our LIMS system at 75%-125% reflect the requirements of a regulatory agency that represents a large amount of our work. However, the associated samples are not from this agency and are therefore held to our in-house statistical limits of 50%-132% per method requirements. The LCS is within criteria and no further action is required. The RPD and RER of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) recovered outside control limits. However, the LCS and LCSD % recoveries were within acceptable statistical limits.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 3 coolers at receipt time were 24.6º C, 24.6º C and 25.8º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gamma prep batch 620138 The detection goal of 20 pCi/L was not met for Cs-137 for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This is due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 activity is well below the RL and MDC. GW-28 (160-50637-3) Many isotopes requested by gamma spectrometry analysis do not have any gamma emissions, the gamma emissions they do have are very poor, and/or are reported by assuming secular equilibrium with a longer-lived parent (or vice-versa). For example, Th-232 (which does not have a good gamma-ray) is often reported assuming the shorter-lived Ra-228 daughter is in equilibrium with the Th-232 parent. Or, Pb-214 and/or Bi-214, daughters of potentially volatile Rn-222 in the Ra-226 decay chain, may not be in equilibrium with the parent unless sufficient time has been allowed since the break in equilibrium (e.g. 21 days in the case of Ra-226-supported ingrowth). The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 The detection goal of 250 pCi/L was not met for K40 for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This is due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 activity is well below the RL and MDC.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperatures of the 9 coolers at receipt time were 23.2º C, 23.2º C, 23.6º C, 23.7º C, 23.9º C, 24.6º C, 24.6º C, 24.9º C and 25.8º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gamma Prep batch 620138 Many isotopes requested by gamma spectrometry analysis do not have any gamma emissions, the gamma emissions they do have are very poor, and/or are reported by assuming secular equilibrium with a longer-lived parent (or vice-versa). For example, Th-232 (which does not have a good gamma-ray) is often reported assuming the shorter-lived Ra-228 daughter is in equilibrium with the Th-232 parent. Or, Pb-214 and/or Bi-214, daughters of potentially volatile Rn-222 in the Ra-226 decay chain, may not be in equilibrium with the parent unless sufficient time has been allowed since the break in equilibrium (e.g. 21 days in the case of Ra-226-supported ingrowth). The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 The detection goal of 250 pCi/L was not met for K40 for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This is due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data.

The detection goal was not met for the following samples:GW-19A (160-50639-7) and GW-141 (160-50639-10).Samples were prepped at a reduced volume due to the presence of matrix interferences. Analytical results are reported with the detection limit achieved. A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing).GW-102 (160-50639-1), GW-823 (160-50639-2), GW-95 (160-50639-3), GW-27 (160-50639-4), P3-95 NECR (160-50639-5), P3-97 NECR (160-50639-6), GW-19A (160-50639-7), GW-89 (160-50639-8), GW-88 (160-50639-9), GW-141 (160-50639-10), GW-109 (160-50639-11), (LCS 160-620140/2-A), (MB 160-620140/1-A) and (160-50639-A-1-D DU) Plutonium Prep Batch 620135 The following samples were prepared at a reduced aliquot due to matrix interference (high salt): GW-102 (160-50639-1), GW-823 (160-50639-2), GW-95 (160-50639-3), GW-27 (160-50639-4), P3-95 NECR (160-50639-5), P3-97 NECR (160-50639-6), GW-19A (160-50639-7), GW-89 (160-50639-8), GW-88 (160-50639-9), GW-141 (160-50639-10), GW-109 (160-50639-11) and (160-50639-A-1 DU).

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 6 coolers at receipt time were 23.0º C, 23.2º C, 23.2º C, 23.4º C, 23.6º C and 23.6º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Gross Beta batch 623626 The sample duplicate (DUP) precision for Gross Beta was outside control limits. Sample matrix interference is suspected due to high residual mass and high salts.(160-50987-C-10-F DU) Gamma prep batch 623607 The detection goal of 20 pCi/L was not met for Cs-137 for the following sample. An elevated MDC can occur when higher background counts are applied to a peak ROI. This is due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 activity is well below the RL and MDC. GW-36 (160-50987-4), GW-107 (160-50987-7) and GW-129 (160-50987-10) Many isotopes requested by gamma spectrometry analysis do not have any gamma emissions, the gamma emissions they do have are very poor, and/or are reported by assuming secular equilibrium with a longer-lived parent (or vice-versa). For example, Th-232 (which does not have a good gamma-ray) is often reported assuming the shorter-lived Ra-228 daughter is in equilibrium with the Th-232 parent. Or, Pb-214 and/or Bi-214, daughters of potentially volatile Rn-222 in the Ra-226 decay chain, may not be in equilibrium with the parent unless sufficient time has been allowed since the break in equilibrium (e.g. 21 days in the case of Ra-226-supported ingrowth). The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 Eurofins St. Louis Page 4 of 53 9/14/2023 1 2 3 4 5 6 7 8 9 10 11 12 Case Narrative Client: Energy Solutions, LLC Job ID: 160-50987-1 Project/Site: ANNUAL LARW Job ID: 160-50987-1 (Continued) Laboratory: Eurofins St. Louis (Continued) Neptunium batch 623601 Manual integration was performed on the following sample(s) due to tailing.GW-107 (160-50987-7). The laboratory control sample(LCS) recovery is outside the upper QC limit indicating a potential positive bias for that analyte. This analyte was not observed above the MDC/RL in the associated samples; therefore the sample data is not adversely affected by this excursion. The data have been reported with this narrative. (LCS 160-623601/2-A) The following samples were prepared at a reduced aliquot due to matrix high in salts: GW-110 (160-50987-1), GW-111 (160-50987-2), GW-112 (160-50987-3), GW-36 (160-50987-4), GW-58 (160-50987-5), GW-108 (160-50987-6), GW-107 (160-50987-7), GW-106 (160-50987-8), GW-140 (160-50987-9), GW-129 (160-50987-10) and (160-50987-B-3 DU). Isotopic Thorium batch 623613 A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing). The following samples were prepared at a reduced aliquot due to matrix high in salts: GW-110 (160-50987-1), GW-111 (160-50987-2), GW-112 (160-50987-3), GW-36 (160-50987-4), GW-58 (160-50987-5), GW-108 (160-50987-6), GW-107 (160-50987-7), GW-106 (160-50987-8), GW-140 (160-50987-9), GW-129 (160-50987-10) and (160-50987-B-3 DU). The sample duplicate (DUP) precision for Thorium-230 was outside control limits. Sample matrix interference was identified and documented during prep. (160-50987-B-3-H DU) Uranium Prep Batch 623614 The following samples were prepared at a reduced aliquot due to matrix high in salts: GW-110 (160-50987-1), GW-111 (160-50987-2), GW-112 (160-50987-3), GW-36 (160-50987-4), GW-58 (160-50987-5), GW-108 (160-50987-6), GW-107 (160-50987-7), GW-106 (160-50987-8), GW-140 (160-50987-9), GW-129 (160-50987-10) and (160-50987-B-3 DU). Strontium-90 by Eichrom Prep Batch 623449 The following samples were prepared at a reduced aliquot due to Matrix: GW-110 (160-50987-1), GW-111 (160-50987-2), GW-112 (160-50987-3), GW-36 (160-50987-4), GW-58 (160-50987-5), GW-108 (160-50987-6), GW-107 (160-50987-7), GW-106 (160-50987-8), GW-140 (160-50987-9), GW-129 (160-50987-10) and (160-50987-B-3 DU). A laboratory control sample/ laboratory control sample duplicate (LCS/LCSD) were prepared instead of a sample duplicate (DUP) to demonstrate batch precision. A LCSD was prepped due to matrix interference. The following samples did not meet the requested limit (RL) due to the low carrier yields outside the 30-110% limits: GW-110 (160-50987-1), GW-36 (160-50987-4), GW-58 (160-50987-5), GW-108 (160-50987-6) and (160-50987-B-3-B DU). The samples were prepped at reduced volume to minimize potential matrix interferences visually noted by the analyst during sample preparation. The data have been reported with this narrative. The following sample had Sr carrier recovery below the 30% QC limit: GW-111 (160-50987-2), GW-112 (160-50987-3), GW-107 (160-50987-7), GW-106 (160-50987-8), GW-140 (160-50987-9) and GW-129 (160-50987-10). The detection limit was achieved; therefore, the data have been reported with this narrative. The LCSD recovered at 153% which is outside the 75-125 limits. The LCS recovery was within the 75-125 QC limits. Additionally the primary purpose of the LCSD is to demonstrate method precision. The RPD between the LCS/LCSD passed. Original results will be qualified and reported. The following samples have an RER (replicate error ratio) result outside of the acceptance criteria of 1 (1.49) for Sr-90. Duplicate precision is demonstrated by acceptable relative percent difference (RPD), within the limit of 40% (30%). The data have been reported with this narrative.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 3 coolers at receipt time were 22.1º C, 23.1º C and 23.2º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Many isotopes requested by gamma spectrometry analysis do not have any gamma emissions, the gamma emissions they do have are very poor, and/or are reported by assuming secular equilibrium with a longer-lived parent (or vice-versa). For example, Th-232 (which does not have a good gamma-ray) is often reported assuming the shorter-lived Ra-228 daughter is in equilibrium with the Th-232 parent. Or, Pb-214 and/or Bi-214, daughters of potentially volatile Rn-222 in the Ra-226 decay chain, may not be in equilibrium with the parent unless sufficient time has been allowed since the break in equilibrium (e.g. 21 days in the case of Ra-226-supported ingrowth). The client should ensure that such inference is acceptable for their sample based upon process knowledge. The following assumptions were made for this report: Inferred from Reported to Analyte Th-234 Pa-234 Th-234 U-238 Pb-210 Po-210 Pb-210 Bi-210 Cs-137 Ba-137m Pb-212 Po-216 Xe-131m Xe-131 Sb-125 Te-125m Ag-108m Ag-108 Rh-106 Ru-106 Pb-212 Th-228 Pb-212 Ra-224 U-235 Th-231 Ac-228 Th-232 Ac-228 Ra-228 Th-227 Ra-223 Th-227 Ac-227 Th-227 Bi-211 Th-227 Pb-211 Bi-214 Ra-226 The detection goal of 20 pCi/L was not met for Cs-137 for the following samples in prep batch 160-623607: MW POND (160-50988-1), 1995 POND (160-50988-2) and 1997 POND (160-50988-3). An elevated MDC can occur when higher background counts are applied to a peak ROI. This is due to the relatively small size of the peak or subsequent “force-fit” of the non-existent peak which resulted in higher than normal background counts due to statistical fluctuations in the Compton baseline. The laboratory does not believe this adversely affects the data, the Cs-137 activity is well below the RL and MDC. Gross Beta The sample duplicate (160-50987-C-10-F DU) precision for Gross Alpha Gross Beta in prep batch 160-623626 was outside control limits. Sample matrix interference is suspected due to high residual mass and high salts. Isotopic Neptunium The laboratory control sample (LCS 160-623601/2-A) associated with prep batch 160-623601 recovery is outside the upper QC limit Eurofins St. Louis Page 4 of 39 9/14/2023 1 2 3 4 5 6 7 8 9 10 11 12 Case Narrative Client: Energy Solutions, LLC Job ID: 160-50988-1 Project/Site: ANNUAL PONDS Job ID: 160-50988-1 (Continued) Laboratory: Eurofins St. Louis (Continued) indicating a potential positive bias for that analyte. This analyte was not observed above the MDC/RL in the associated samples; therefore, the sample data is not adversely affected by this excursion. The data have been reported with this narrative. The following samples were prepared at a reduced aliquot due to matrix high in salts: MW POND (160-50988-1), 1995 POND (160-50988-2), 1997 POND (160-50988-3), NWC POND (160-50988-4) and 2000 POND (160-50988-5). Isotopic Thorium A blank population correction was applied to account for contributions to the analyte count rate from sources other than the sample itself. Interferences may include, but are not limited to, impurities in reagents, tracers, or glassware, or effects due to the measurement process (such as tailing). The sample duplicate (DUP) precision for Thorium-230 was outside control limits. Sample matrix interference was identified and documented in prep. (160-50987-B-3-H DU) The following samples were prepared at a reduced aliquot due to matrix high in salts: MW POND (160-50988-1), 1995 POND (160-50988-2), 1997 POND (160-50988-3), NWC POND (160-50988-4) and 2000 POND (160-50988-5). Isotopic Uranium The detection goal was not met for the following sample in prep batch 160-623614 due to a reduction of sample size attributed to the level activity and matrix: 2000 POND (160-50988-5). Analytical results are reported with the detection limit achieved. The following samples were prepared at a reduced aliquot due to matrix high in salts: MW POND (160-50988-1), 1995 POND (160-50988-2), 1997 POND (160-50988-3), NWC POND (160-50988-4) and 2000 POND (160-50988-5). Strontium-90 by Eichrom The following samples in Prep Batch 160-623449 were prepared at a reduced aliquot due to Matrix: MW POND (160-50988-1), 1995 POND (160-50988-2), 1997 POND (160-50988-3), NWC POND (160-50988-4) and 2000 POND (160-50988-5). A laboratory control sample/ laboratory control sample duplicate (LCS/LCSD) were prepared instead of a sample duplicate (DUP) to demonstrate batch precision. A LCSD was prepped due to matrix interference. The sample duplicate (160-50987-B-3-B DU) associated with Prep Batch 160-623449 did not meet the requested limit (RL) due to the reduced sample volume attributed to the presence of matrix interference. During preparation the analyst visually noted matrix effects. The data have been reported with this narrative. The following sample had Sr carrier recovery below the 30% QC limit: 1995 POND (160-50988-2) and (160-50987-B-3-A). The detection limit was achieved; therefore, the data have been reported with this narrative. The following samples did not meet the requested limit (RL) due to the low carrier yields outside the 30-110% limits: (160-50987-B-3-B DU). The samples were prepped at reduced volume to minimize potential matrix interferences visually noted by the analyst during sample preparation. The data have been reported with this narrative. The laboratory control sample duplicate (LCSD) associated with prep batch 160-623449 recovered at 153% which is outside the 75-125 limits. The laboratory control sample (LCS) recovery was within the 75-125 QC limits. Additionally, the primary purpose of the LCSD is to demonstrate method precision. The RPD between the LCS/LCSD passed. Original results will be qualified and reported. The laboratory control sample duplicate (LCSD 160-623449/3-A) associated with prep batch 160-623449 has an RER (replicate error ratio) result outside of the acceptance criteria of 1 (1.49) for Sr-90. Duplicate precision is demonstrated by acceptable relative percent difference (RPD), within the limit of 40% (30%). The data have been reported with this narrative. SM7500 Iodine-129 The following samples in prep batch 160-624606 have been prepped at a reduced aliquot due to historical matrix interference (high salt). MW POND (160-50988-1), 1995 POND (160-50988-2), 1997 POND (160-50988-3), NWC POND (160-50988-4) and 2000 POND (160-50988-5) No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved. The temperatures of the 2 coolers at receipt time were 19.1º C and 19.2º C. RAD Any minimum detectable concentration (MDC), critical value (DLC), or Safe Drinking Water Act detection limit (SDWA DL) is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date. Method A-01-R: Isotopic Uranium batch 629901 The detection goal was not met for the following sample. Sample was prepped at a reduced volume due to the presence of matrix interferences: P3-95 SWC (160-51569-8). Analytical results are reported with the detection limit achieved. Radium-228 Prep Batch 630064 The following samples were prepared at a reduced aliquot due to Matrix: GW-77 (160-51569-3), GW-451 (160-51569-5), GW-126 (160-51569-6) and (160-51569-A-3 DU). A laboratory control sample/ laboratory control sample duplicate (LCS/LCSD) were prepared instead of a sample duplicate (DUP) to demonstrate batch precision. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Eurofins Environment Testing attests to the validity of the laboratory data generated by Eurofins facilities reported herein.All analyses performed by Eurofins Environment Testing facilities were done using established laboratory SOPs that incorporate QA/QC procedures described in the application methods.Eurofins Environment Testing's operations groups have reviewed the data for compliance with the laboratory QA/QC plan,and data have been found to be compliant with laboratory protocols unless otherwise noted below. The test results in this report meet all NELAP requirements for parameters for which accreditation is required or available.Any exceptions to NELAP requirements are noted in this report. Calculations are performed before rounding to avoid round-off errors in calculated results. Proper preservation was noted for the methods performed on these samples,unless otherwise detailed below. All soil/sediment sample results for radiochemistry analyses are based upon sample as dried and disaggregated with the exception of tritium,carbon-14,and iodine-129 by gamma spectroscopy or unless requested as wet weight by the client. Any minimum detectable concentration (MDC),critical value (DLC),or Safe Drinking Water Act detection limit (SDWA DL)is sample-specific unless otherwise stated elsewhere in this narrative. Radiochemistry sample results are reported with the count date/time applied as the Activity Reference Date.

Several analytes failed the recovery criteria low for the MS of sample 280-175643-9 in batch 280-610633. 1,1,2,2-Tetrachloroethane failed the recovery criteria high for the MSD of sample 280-175643-9 in batch 280-610633. Several analytes exceeded the RPD limit. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. POLYCHLORINATED BIPHENYLS (PCBS) Samples 1B (280-175174-1), 2B (280-175174-2), 3B (280-175174-3), 4B (280-175174-4) and 5B (280-175174-5) were analyzed for polychlorinated biphenyls (PCBs) in accordance with SW 846 8082. The samples were prepared on 04/24/2023 and analyzed on 05/04/2023. TestAmerica Denver’s practice for the reporting of dual column data in packages requiring forms and/or raw data is to report the surrogates from both columns, and the preferred result for any given target analyte from the analyst selected column. The preferred results for target analytes and surrogates are reported as PRIMARY on the Sample Datasheets. The following samples in preparation batch 280-609796 were yellow in color: 1B (280-175174-1) and 2B (280-175174-2).

The reporting limits (RLs) have been adjusted proportionately. An initial volume of 1050.6 mL was used for these extractions. Due to the high density of the sample matrix (>1.0 g/mL), the initial volume used for the following sample in preparation batch 280-609796 deviated from the standard procedure: 3B (280-175174-3). The reporting limits (RLs) have been adjusted proportionately. An initial volume of 1055.8 mL was used for these extractions. The following samples in preparation batch 280-609796 and analytical batch 280-611226 required a sulfuric acid clean-up, via EPA Method 3665A, to reduce matrix interferences: 1B (280-175174-1), 2B (280-175174-2), 3B (280-175174-3), 4B (280-175174-4), 5B (280-175174-5), (LCS 280-609796/4-A), (LCSD 280-609796/5-A) and (MB 280-609796/1-A). The continuing calibration verification (CCV) associated with preparation batch 280-609796 and analytical batch 280-611226 recovered above the upper control limit for DCB Decachlorobiphenyl (Surr), PCB-1016, PCB-1260 and Tetrachloro-m-xylene (Surr). The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported. The associated samples are impacted: 1B (280-175174-1), 2B (280-175174-2), 3B (280-175174-3), 4B (280-175174-4), 5B (280-175174-5), (CCV 280-611226/12) and (CCV 280-611226/26). The Tetrachloro-m-xylene surrogate recovery for the following samples in preparation batch 280-609796 and analytical batch 280-611226 was outside acceptance limits (high biased) on the primary column due to matrix interference: (MB 280-609796/1-A). The recovery is within acceptance limits on the other column, indicating that the extraction process was in control. PCB-1016 and PCB-1260 failed the recovery criteria high for LCSD 280-609796/5-A. Refer to the QC report for details. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 04/19/2023; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was C. VOLATILE ORGANIC COMPOUNDS (GC-MS) Samples 6B (280-175206-1), 7B (280-175206-2), 8B (280-175206-3), 9B (280-175206-4), 10B (280-175206-5) and TB041823 (280-175206-6) were analyzed for volatile organic compounds (GC-MS) in accordance with EPA SW-846 Method 8260B. The samples were analyzed on 04/28/2023 and 04/29/2023. The continuing calibration verification (CCV) associated with batch 280-610649 recovered outside the control limit of 35%D for Bromomethane (55.6%D). This analyte is a poor performer. Bromomethane failed the recovery criteria high for LCSD 280-610649/4. Refer to the QC report for details. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. POLYCHLORINATED BIPHENYLS (PCBS) Samples 6B (280-175206-1), 7B (280-175206-2), 8B (280-175206-3), 9B (280-175206-4) and 10B (280-175206-5) were analyzed for polychlorinated biphenyls (PCBs) in accordance with SW 846 8082. The samples were prepared on 04/25/2023 and analyzed on 04/28/2023. TestAmerica Denver’s practice for the reporting of dual column data in packages requiring forms and/or raw data is to report the surrogates from both columns, and the preferred result for any given target analyte from the analyst selected column. The preferred results for target analytes and surrogates are reported as PRIMARY on the Sample Datasheets. Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 280-610087. The following samples in preparation batch 280-610087 were pale yellow in color: 8B (280-175206-3), 9B (280-175206-4) and 10B (280-175206-5). Due to the high density of the sample matrix (>1.0 g/mL), the initial volume used for the following sample in preparation batch 280-610087 Eurofins Denver Page 5 of 36 5/2/2023 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Case Narrative Client: Energy Solutions, LLC Job ID: 280-175206-1 Project/Site: Salt Lake City EC-98076 Job ID: 280-175206-1 (Continued) Laboratory: Eurofins Denver (Continued) deviated from the standard procedure: 6B (280-175206-1). The reporting limits (RLs) have been adjusted proportionately. An initial volume of 1043.0 mL was used. Due to the high density of the sample matrix (>1.0 g/mL), the initial volume used for the following sample in preparation batch 280-610087 deviated from the standard procedure: 7B (280-175206-2). The reporting limits (RLs) have been adjusted proportionately. An initial volume of 1042.8 mL was used. Due to the high density of the sample matrix (>1.0 g/mL), the initial volume used for the following sample in preparation batch 280-610087 deviated from the standard procedure: 8B (280-175206-3). The reporting limits (RLs) have been adjusted proportionately. An initial volume of 1046.5 mL was used. Due to the high density of the sample matrix (>1.0 g/mL), the initial volume used for the following sample in preparation batch 280-610087 deviated from the standard procedure: 9B (280-175206-4). The reporting limits (RLs) have been adjusted proportionately. An initial volume of 1055.4 mL was used. Due to the high density of the sample matrix (>1.0 g/mL), the initial volume used for the following sample in preparation batch 280-610087 deviated from the standard procedure: 10B (280-175206-5). The reporting limits (RLs) have been adjusted proportionately. An initial volume of 1050.3 mL was used. The following samples in preparation batch 280-610087 and analytical batch 280-610361 required a sulfuric acid clean-up, via EPA Method 3665A, to reduce matrix interferences: 6B (280-175206-1), 7B (280-175206-2), 8B (280-175206-3), 9B (280-175206-4), 10B (280-175206-5), (LCS 280-610087/4-A), (LCSD 280-610087/5-A) and (MB 280-610087/1-A).

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. Receipt The samples were received on 4/21/2023 9:35 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperatures of the 2 coolers at receipt time were 0.7º C and 1.1º C.

The samples were analyzed on 05/04/2023. Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate/sample duplicate (MS/MSD/DUP) associated with analytical batch 280-611173. an LCS/LCSD was prepared, run, and analyzed to ensure precision and accuracy for sample results. Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with analytical batch 280-611346. An LCS/LCSD was analyzed to provide batch precision and accuracy. The reporting limit provided for the following analyte(s) falls below the laboratory's lowest calibration standard: Iodomethane (5 ug/L). Results reported below the lowest calibration standard are estimated. The continuing calibration verification (CCV) associated with batch 280-611173 recovered above the upper control limit for Iodomethane (62.7%D, 35%D Limit). All associated samples were ND so the samples are reported. The continuing calibration verification (CCV) associated with batch 280-611173 recovered above the upper control limit for 2-Chloro-1,3-butadiene (35.8%D, 35%D Limit). All associated samples were ND so the samples are reported The continuing calibration verification (CCV) associated with batch 280-611346 recovered above the upper control limit for bromomethane (+67%D, limit 35%D). The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported. Dibromofluoromethane (Surr) failed the surrogate recovery criteria high for 6A (280-175427-1). Dibromofluoromethane (Surr) failed the surrogate recovery criteria high for 8A (280-175427-3).

The recoveries for both in the LCS and LCSD are within control limits, only the RPD is outside of limits. The following analyte(s) recovered outside control limits for the LCS associated with analytical batch 280-611173: Vinyl acetate (53% recovered, 61-139% recovery limits). This is not indicative of a systematic control problem because these were random marginal exceedances. Qualified results have been reported. The laboratory control sample (LCS) for analytical batch 280-611173 recovered outside control limits for the following analytes: Iodomethane (163% recovered, 37-145% recovery limits). These analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported. The RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for analytical batch 280-611173 recovered outside control limits for the following analytes: 2-Chloro-1,3-butadiene (RPD 21, RPD Limit 20). The recoveries for both in the LCS and LCSD are within control limits, only the RPD is outside of limits. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. Receipt The samples were received on 4/25/2023 10:15 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperatures of the 2 coolers at receipt time were 0.4º C and 2.0º C. Receipt Exceptions There is a cooler missing for this job; containers & tests were logged per volume received. The missing volume was received on 04/26/2023 at 09:45: 1A (280-175561-1), 2A (280-175561-2), 3A (280-175561-3), 4A (280-175561-4), 5A (280-175561-5) and TB042423 (280-175561-6).

The samples were analyzed on 05/04/2023 and 05/05/2023. The method requirement for no headspace was not met. The following volatile sample in batch 280-611345 were analyzed with significant headspace in the sample container(s): 3A (280-175561-3). Significant headspace is defined as a bubble greater than 6 mm in diameter. The following sample(s) was collected in a properly preserved vial; however, the pH was outside the required criteria when verified by the laboratory. The sample in batch 280-611345 was analyzed outside the 7-day holding time specified for unpreserved samples but within the 14-day holding time specified for preserved samples: 3A (280-175561-3). The sample had a reported pH of 6. The continuing calibration verification (CCV) associated with batch 280-611345 recovered below the lower control limit for the following analytes: Bromomethane (-53.2%D, 35%D Limit) and iodomethane (-35.2%D, 35%D Limit). The associated sample is impacted: (CCV 280-611345/2). These analytes passed within LCS/LCSD requirements and limits. Acetone exceeded the RPD limit for the MSD of sample 550-201218-6 in batch 280-611345. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

The reporting limits (RLs) have been adjusted proportionately. An initial volume of 100 mL out of 1000 was used for these extractions. The following sample in preparation batch 280-610552 was dark red in color and thick: 3A (280-175561-3). The following sample in preparation batch 280-610552 was yellow in color: 1A (280-175561-1). The following sample in preparation batch 280-610552 was light yellow in color: 2A (280-175561-2). The following samples in preparation batch 280-610552 were pale yellow in color: 4A (280-175561-4) and 5A (280-175561-5). The following samples in preparation batch 280-610552 and analytical batch 280-610693 required a sulfuric acid clean-up, via EPA Method 3665A, to reduce matrix interferences: 1A (280-175561-1), 2A (280-175561-2), 3A (280-175561-3), 4A (280-175561-4), 5A (280-175561-5), (LCS 280-610552/2-A), (LCSD 280-610552/3-A) and (MB 280-610552/1-A). The continuing calibration verification (CCV) associated with preparation batch 280-610552 and analytical batch 280-610693 recovered above the upper control limit for Aroclor 1016. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported. The associated samples are impacted: 1A (280-175561-1), 2A (280-175561-2), 3A (280-175561-3), 4A (280-175561-4), 5A (280-175561-5) and (CCV 280-610693/17). No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

The most viable result has been reported as non-target analytes have been diluted out of the sample.MW POND (280-178076-1), 1995 POND (280-178076-2) and 1997 POND (280-178076-3). Due to the concentration of chloride in the spiked sample, the matrix spike/ matrix spike duplicate result was higher than the highest calibration point for this analyte. Non-homogeneity/ sample matrix interference is suspected as the matrix spike duplicate % recoveries are not within % recovery limits. (280-178137-A-6), (280-178137-A-6 MS) and (280-178137-A-6 MSD) Bromide failed the recovery criteria high for the MSD of sample 280-178137-6 in batch 280-617997.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. The presence of the '4' qualifier indicates analytes where the concentration in the unspiked sample exceeded four times the spiking amount. Receipt The samples were received on 6/21/2023 10:50 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperature of the cooler at receipt was 0.3º C. POLYCHLORINATED BIPHENYLS (PCBS) Sample NWC POND (280-178144-1) was analyzed for polychlorinated biphenyls (PCBs) in accordance with SW 846 8082. The samples were prepared on 06/22/2023 and analyzed on 06/23/2023. TestAmerica Denver’s practice for the reporting of dual column data in packages requiring forms and/or raw data is to report the surrogates from both columns, and the preferred result for any given target analyte from the analyst selected column. The preferred results for target analytes and surrogates are reported as PRIMARY on the Sample Datasheets. The following samples in preparation batch 280-617088 and analytical batch 280-617216 required a sulfuric acid clean-up, via EPA Method 3665A, to reduce matrix interferences: NWC POND (280-178144-1), (LCS 280-617088/4-A), (LCSD 280-617088/5-A) and (MB 280-617088/1-A).

ANIONS (28 DAYS) Samples NWC POND (280-178144-1) and 2000 POND (280-178144-2) were analyzed for anions (28 days) in accordance with EPA Method 300.0 (28 Days). The samples were analyzed on 06/30/2023. Due to the concentration of bromide in the spiked sample, the matrix spike/ matrix spike duplicate result was higher than the highest calibration point for this analyte. Non-homogeneity/ sample matrix interference is suspected as the % recoveries are not within % recovery limits. (280-178139-A-9), (280-178139-A-9 MS) and (280-178139-A-9 MSD) Due to the concentration of chloride in the spiked sample, the matrix spike/ matrix spike duplicate result was higher than the highest calibration point for this analyte.

No preparation issues were noted. Method Blanks All blank values were within method acceptance criteria. No blank values exceeded the minimum reporting limit for any analysis in this work order. Laboratory Control Samples All laboratory control samples were within method acceptance criteria. The LCS percent recovery for Chrysene in BXE1031-BS1 exceeded the upper acceptance limits. Assoicated samples were all non-detect and therefore accepted and reported for this parameter. It is important to note that certain flags on an individual analyte do not constitute failure of the method as a whole. EPA methodologies recognize that it may not be possible for every compound to meet all recovery or percent difference criteria . The batch passed required method criteria for these analytes. Method Spikes All method spike recoveries were within method acceptance criteria, except as noted by qualifying flags. Method Spike Duplicates All method spike duplicates were within method acceptance criteria, except as noted by qualifying flags. Corrective Actions There are no corrective actions associated with this work order. www.ChemtechFord.com Project Name: 11e.(2) / LARW 76234 CtF WO#: 23E1675 Page 2 of 20 xx Chemtech-Ford Laboratories Serving the Intermountain West Since 1953 Certificate of Analysis 9632 South 500 West Sandy, UT 84070 O:(801) 262-7299 F: (866) 792-0093 www.ChemtechFord.com Energy Solutions Robert Sobocinski 299 South Main, Suite 1700 Salt Lake City, UT 84111 PO#: Receipt: Date Reported: Project Name: 713975 5/18/23 17:18 @ 1.8 °C 6/7/2023 11e.(2) / LARW 76234 Sample ID: GW-823 Lab ID: 23E1675-01Matrix: Water Flag(s)Units Analysis Date/Time Date Sampled: 5/18/23 11:38 Preparation Date/Time Sampled By: R Sobocinski/N Clarke Minimum Reporting Limit MethodResult Calculations %6/6/236/6/23SM 1030 E-8.2Cation/Anion Balance Inorganic mg/L 5/23/235/23/231.0 SM 2320 B108Alkalinity -
