(WSP) has prepared this letter report for the Groundwater Sampling activities conducted at the 3D Storage property, owned by DS Investments LLC (property owner), located at 50 East 1100 North, North Salt Lake, Utah (Site), west of the former General Electric (GE) North Salt Lake facility. WSP personnel conducted the March 2025 groundwater sampling activities on March 24, 2025 in accordance with the offsite assessment scope of work provided on August 11, 2022, and accepted by Utah Department of Environmental Quality (UDEQ), Division of Environmental Response and Remediation (DERR) on August 18, 2022. BACKGROUND On September 8, 2022, monitoring wells A-1 and A-2 were installed to a depth of approximately 20 feet below ground surface (bgs) and ground water samples were collected. Following the initial September 2022 offsite monitoring well installation and sampling and analysis event, the UDEQ requested that additional groundwater sampling events be conducted from the A-1 and A-2 monitoring wells in conjunction with the GE Vernova North Salt Lake onsite monitoring events. Monitoring wells A-3 through A-12 were installed to a depth of approximately 15 feet bgs between the dates of March 27, 2024 and April 9, 2024. WSP personnel conducted the site monitoring and sampling activities discussed following installation. Well locations are shown on the site layout map as Figure 2. Monitoring well construction details are provided in Table 1. On August 26, 2024, WSP proposed modifications to the sampling plan in response to trends observed in previous groundwater results, and the Utah DERR approved this request over email on August 27, 2024. The modifications include targeted sampling and analysis of 1,4-dioxane in wells A-1, A-2, A-3, and A-10, and volatile organic compounds (VOCs) and 1,4- Page 2 dioxane in wells A-1, A-2, and A-10. The remaining wells were monitored by gauging only. To date eight offsite sampling events have been completed of wells A-1 and A-2. GROUNDWATER SAMPLING Groundwater elevation measurements were collected from all wells on March 11, 2025 and are summarized in Table 2. Field data sheets (FDS) were used to record the depth to water (DTW), total well depth, and calculated well casing volume for each well. The FDS are provided in Appendix A. Groundwater samples were collected on March 24, 2025 and submitted for laboratory analysis. Monitoring wells A-1 through A-3, and A-10 were purged and sampled with a peristaltic pump using low flow purging and sampling procedures (EPA, 2017), as detailed in the approved Site Characterization Work Plan (SCW). Water quality parameters of temperature, pH, specific conductivity, dissolved oxygen, oxidation-reduction potential (ORP), and turbidity were measured during well purging at five-minute intervals and recorded on the FDS (Appendix A). The groundwater samples were collected into clean, laboratory-provided sample containers that contained the preservatives required by the analytical procedure and stored in an ice filled container at approximately 4 degrees Celsius. The collected samples from each well were sent for laboratory analysis for 1,4-dioxane. Additionally, collected samples from A-1, A-2, and A-10 were submitted for volatile organic compounds (VOC) analysis. Groundwater samples were delivered under chain-of-custody documentation to Eurofins Environment Testing America (Eurofins) in Arvada, Colorado via overnight shipping. ANALYTICAL RESULTS The analytical results of the groundwater samples were compared to the EPA Maximum Contaminant Level (MCL) and/or the Tapwater Drinking Water Standard (TDWS) if no MCL is available and summarized in the following section below. The laboratory analytical reports are provided in Appendix B. Volatile Organic Compounds (VOCs) A summary of VOC results and applicable regulatory standards are provided in Table 3. DATA QUALITY Quality Assurance (QA) and quality control (QC) measures for groundwater sampling followed the requirements of the Sampling and Analysis Plan. These measures included standardized procedures for samples collection, preservation, delivery, and laboratory analysis. Evaluation of the reliability and usability of data was done by analyzing QC samples. LABORATORY QA/QC The groundwater samples were analyzed for VOCs and 1,4-dioxane at Eurofins in Arvada, Colorado. Eurofins is a Utah Certified Laboratory under Utah Rule R444-14. Laboratory Quality Assurance/Quality Control (QA/QC) procedures were followed in accordance with the analytical methods used, and standard laboratory procedures. The Page 3 internal laboratory QA/QC for water samples included analysis of method blank, laboratory control samples, MS/MSD, and surrogates. The laboratory Analytical Reports (Appendix B) include QC data for the sample analyses, and a project narrative that summarizes the review of QC parameters and explains any deviation from the analytical methods. Any deviation from established control limits is flagged by the laboratory and noted in the analytical report by a qualifier letter, as described below. • VOCs - The continuing calibration verification (CCV) associated with batch 280- 690121 recovered above the upper control limit for bromomethane. The samples associated with this CCV were non-detects for the affected analyte; therefore, the data has been reported. The associated samples are impacted: A-10 (280-204937-4), (CCV 280-690121/2) and (280-204941-D-4). The quality of the data is acceptable. No data was rejected based on QA/QC parameters and the analytical data is considered usable for the intended use.

Regulated compliance samples (e.g.SDWA,NPDES)must comply with the associated agency requirements/permits. Receipt The samples were received on 3/26/2025 9:00 AM.Unless otherwise noted below,the samples arrived in good condition,and,where required,properly preserved and on ice.The temperatures of the 3 coolers at receipt time were 2.2°C,2.4°C and 2.5°C. Method 8260D -Volatile Organic Compounds by GC/MS Samples A-1 (280-204937-1),A-2 (280-204937-2),A-10 (280-204937-4)and TB-032425-02 (280-204937-5)were analyzed for Volatile Organic Compounds by GC/MS.The samples were analyzed on 4/2/2025. The continuing calibration verification (CCV)associated with batch 280-690121 recovered above the upper control limit for Bromomethane.The samples associated with this CCV were non-detects for the affected analyte;therefore, the data has been reported.The associated samples are impacted:A-10 (280-204937-4),(CCV 280-690121/2)and (280-204941-D-4). Method 8260D SIM -Volatile Organic Compounds (GC/MS) Samples A-1 (280-204937-1),A-2 (280-204937-2),A-3 (280-204937-3)and A-10 (280-204937-4)were analyzed for Volatile Organic Compounds (GC/MS).The samples were analyzed on 3/28/2025.
