INTRODUCTION On behalf of Paxton Project, LLC (Paxton), Geosyntec Consultants (Geosyntec) has prepared this Site Characterization Report (SCR) for the planned Paxton residential development project located at 203 to 225 West Paxton Avenue in Salt Lake City, Utah (Site). This SCR presents results of the soil, soil gas, and groundwater characterization samples that were collected in accordance with the Site Characterization Work Plan (SCWP) and SCWP Addendum prepared for the project (Geosyntec 2024a and 20204b). The above samples were collected to support the preparation of a Remedial Action Plan (RAP) to address identified impacts and facilitate the planned development of the Site. The characterization and remediation of the Site are being conducted under the Utah Department of Environmental Quality (UDEQ), Division of Environmental Response and Remediation’s (DERR) Voluntary Cleanup Program (VCP), Voluntary Cleanup Site #C-129. 1.1 Site Location and Description The Site is approximately 0.71 acres in size and was previously occupied by a towing/auto repair business (Tucker Towing) and two residential dwellings. The location and boundaries of the Site are presented on Figure 1. The general layout of the Site and key features are presented on Figure 2. It is noted that the Site buildings and structures have been demolished down to the foundations, but were present when the site characterization activities were conducted. Prior to the demolition, required asbestos and lead based paint surveys were conducted and abatement was performed where required. Additionally, small quantities of miscellaneous fuels and chemicals left by the previous owner were removed and removed and managed off-site. Records regarding the demolition and waste management activities were provided to the DERR on November 11, 2024. 1.2 Site Background Based on historical records, the Site was used for residential purposes dating back to at least 1898. Towing and/or auto repair operations began at the Site in the 1940s and continued until June 2024. Paxton is planning to redevelop the property with a multi-unit residential/commercial development and has entered into the DERR VCP to address the impacts that have been observed at the Site (see Section 1.3) as part of the planned development. The Site was accepted into the VCP program on April 1, 2024. 1.3 Previous Investigations Summary Prior to implementation of the characterization activities described herein, previous investigations conducted at the Site included a Phase I Environmental Site Assessment (ESA) and two limited subsurface sampling investigations (Atlas 2023, AGEC 2023a and AGEC 2023b). These previous investigations were conducted in 2023 as part of Paxton’s planned acquisition of the Site. The Phase I ESA identified Recognized Environmental Conditions (RECs) associated with the historic towing/automotive repair activities on the Site including the presence of two former in- Paxton SCR 2 ground hydraulic lifts (the former hydraulic lift located in the southwestern portion of the Site was identified in the Phase I ESA as an “underground vault”). The Phase I ESA also identified the potential for chlorinated solvent impacts from an adjacent RETEP property, which is located to the north of the Site at 216 West Paxton Avenue, as shown on Figure 2 as a REC. The RETEP property is listed on EPA’s Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS) and has undergone investigation by the EPA and DERR related to chlorinated solvent impacts to soil and groundwater (Atlas 2023). The limited subsurface investigations were conducted to determine if the historic auto repair and towing operations and the adjacent RETEP property had adversely impacted the Site. The initial investigation was conducted in September 2023 and included the completion of five borings to collect soil and groundwater samples at potential areas of concern. The subsequent investigation was conducted in October 2023 and included the installation of 10 monitoring wells at representative areas around the Site and the collection of two surface soil samples from areas of surface staining in the storage yard in the center of the Site. All samples were analyzed for oil and grease, total petroleum hydrocarbon diesel and gasoline range organics (TPH-DRO and TPH- GRO), and volatile organic compounds (VOCs). Select samples were also analyzed for Resource Conservation and Recovery Metals (RCRA) metals and polychlorinated biphenyls (PCBs). The previous sample locations are presented on Figure 3. A tabular summary of the previous analytical results is provided in Appendix A (AGEC 2023a and AGEC 2023b). The prior investigation results were screened against. EPA residential and industrial Regional Screening Levels (RSLs), DERR Initial Screening Levels (ISLs), DERR Risk Based Corrective Action (RBCA) Tier 1 Screening Levels and EPA Maximum Contaminant Levels (MCLs) as relevant and appropriate based on media type. Based on the analytical results from the previous investigations, the following key findings were identified: Petroleum related constituents (oil and grease and/or TPH-DRO) were detected above screening levels in soil samples from three locations. These include boring GP-5 (completed next to the former hydraulic lift in the shop building), monitoring well MW-3 (completed in the northeast corner of the Site), and SS-1 (collected from a stained area in the storage yard). No other exceedances for petroleum related constituents were observed in any of the other soil samples that were collected. Petroleum related constituents (TPH-DRO/GRO and/or benzene) were detected above screening levels in groundwater at three locations. These include boring GP-1 (completed in the north-central portion of the Site), boring GP-5 (completed next to the former hydraulic lift in the shop building), and MW-7 (completed in the central portion of the Site). No other exceedances for petroleum related constituents were observed in any of the other groundwater samples collected from the borings and monitoring wells. Chlorinated VOC concentrations did not exceed screening levels in any soil samples, with the exception of the soil sample that was collected in boring GP-4 from 6 to 7 feet below Paxton SCR 3 ground surface (bgs). Trichloroethene was detected in this sample at a concentration exceeding the residential RSL, but below the industrial RSL. This sample appears to have been collected from below the ground water table and the result is likely influenced by impacted groundwater. One or more chlorinated VOC were detected above screening levels in groundwater in four of the five boring locations and seven of the ten monitoring well locations. Observed exceedances included 1,1-dichloroethane, 1,1-dichloroethene, cis-dichloroethene, trans- dichloroethene, tetrachloroethene, trichloroethene and vinyl chloride. No petroleum or chlorinated VOCs were detected above screening levels in the deep monitoring wells (MW-9 and MW-10) that were installed in western portion of the Site. RCRA metals were analyzed in the surface soil samples collected from the storage yard (SS-1 and SS-2), the subsurface soil sample collected from location MW-3 and the groundwater sample collected from boring GP-1 (installed in the north central portion of the Site). With the exception arsenic in soil, no exceedances of the screening levels were identified in the soil or groundwater samples. The reported arsenic concentrations in the soil samples ranged from 5.64 to 8.35 mg/kg. While the observed concentrations exceed the screening levels, the investigation report notes that the concentrations are consistent with background levels of arsenic in soils for the Salt Lake Valley (AGEC 2023b). PCBs were analyzed in the soil samples collected from the boring locations (GP-1 through GP-5). All results were either non-detect or below screening levels. The overall previous investigation results indicated the presence of limited petroleum related impacts to soil and groundwater in select areas. Potential sources were noted to include incidental spills and releases in the storage yard, the historic hydraulic lift in the shop building and a potential unknown source in the northeast corner of the Site (MW-3). Additionally, the detection of chlorinated VOCs in groundwater across the Site were indicated to potentially be related to the RETEP property given their widespread prevalence and the close proximity of that property to the Site. 1.4 Environmental Setting The Site is located approximately 1.5 miles southwest of downtown Salt Lake City, Utah. Land use in the surrounding area is comprised of a mixture of residential, commercial and light industrial properties. The general topography of the surrounding area is flat with a slight slope to the west. 1.5 Geology and Hydrogeology The Site is located within the Salt Lake Valley, which is part of the Great Basin physiographic province of the western United States. It is bordered on the east and northeast by the Wasatch Range, to the northwest by the Great Salt Lake, on the west by the Oquirrh Mountains, and to the south by the Traverse Mountains. The valley is filled with unconsolidated to semi-consolidated sediments with thicknesses reaching up to 4,000 feet in certain areas. The basin fill mainly consists Paxton SCR 4 of fluvial and lacustrine deposits eroded from the surrounding mountains that intermingle with alluvial-fan deposits and, to a lesser degree, deltaic and landslide deposits along the valley margins. Surface deposits in the center of the valley primarily consist of offshore lacustrine silt and clay, which were deposited during the Pleistocene Bonneville lake cycle approximately 12,000 to 29,000 years ago. Based on subsurface borings from the previous site investigations, surface soils are primarily composed of fill from approximately 0 to 2 feet bgs. Surface fill is underlain by predominately by clays with minor silty sand and clayey sand zones up to depth of 45 feet bgs (maximum depth of previous investigation conducted at the Site) (AGEC 2023b). Groundwater has been observed to be present at depths ranging from approximately 4 to 6 feet below ground surface (bgs) with a relatively flat gradient across the Site (AGEC 2023b). Regional groundwater flow is estimated to be towards the west, based on topography. The nearest surface water body to the Site is the Jordan River, which is located approximately one mile west of the Site. Water level measurements collected from the wells as part of the site characterization activities are discussed in Section 3.4. 1.6 Investigation Objectives, Scope and Rational The following site characterization activities were completed in accordance with the SCWP and SCWP Addendum to further characterize the Site and provided data to support the development of the RAP: Soil sampling – Shallow surface and subsurface soil samples were collected from representative areas within the Site to further characterize potential impacts from the storage of vehicles, equipment and potential incidental spills/or leaks of petroleum products. Samples were initially focused in the areas where exposed soil is present, but were expanded to include samples beneath paved surfaces along the northern portion of the Site and beneath the concrete slabs for the shop building and storage building. Soil gas sampling – Soil gas samples were collected at two locations in the central portion of the Site where elevated groundwater concentrations are present. Samples were collected to determine potential soil gas concentrations and evaluate the need for vapor mitigation as part of the planned development. Groundwater sampling – Groundwater samples were collected from the existing monitoring wells to confirm prior groundwater concentrations from the previous investigations and collect additional groundwater elevation measurements to confirm the groundwater flow direction. In conjunction with the monitoring activities, the wells were also resurveyed to establish casing elevations relative to NAVD88 elevation datum. The Site wells were previously surveyed relative to an on-site benchmark. Paxton SCR 5 2. SAMPLING COLLETION PROCEDURES The following section present the sample collection procedures that were used for the surface soil, soil gas and groundwater sampling activities conducted under the SCWP and SCWP Addendum. All sampling and analytical testing was done in accordance with the Quality Assurance Project Plan (QAPP) prepared for the Site (Geosyntec 2024c). 2.1 Soil Sampling Shallow soil samples were collected using a stainless-steel hand auger from 16 representative locations within the Site in accordance with the sampling procedures presented in the QAPP (SOP- 002). Samples were collected 0-6 inches below ground surface (bgs) with additional samples collected at approximately 6-12 inches and 12-18 inches bgs at select locations to aid in vertical delineation. Completed site characterization soil sample locations are shown on Figure 4, along with the sample intervals completed at each location. At locations where asphalt or concrete surfaces were present the samples were collected directly below the engineered surfaces. All samples from 0-6 inches and 6-12 inches bgs were analyzed for RCRA metals, TPH-DRO/GRO, oil and grease and VOCs using the analytical methods specified in Section 2.4. Deeper samples collected from 12-18 inches were only analyzed for the above parameters that were observed to exceed one more screening level based on the initial results from the shallower samples. 2.2 Groundwater Sampling Groundwater samples were collected from 9 of the 10 monitoring wells within the Site. One well (MW-6) could not be located during the sampling and was not sampled. The monitoring well locations are shown on Figure 5. All wells were sampled using a peristaltic pump in accordance with the low-flow sampling procedures presented in the QAPP (SOP-008). The samples were collected at the approximate midpoint of the saturated screen interval. Prior to sampling, fluid level measurements were collected from all wells in accordance with SOP-7 in the QAPP. All groundwater samples were analyzed for TPH-DRO/GRO, oil and grease and VOCs using the analytical methods specified in Section 2.4. Completed well sampling logs are included in Appendix B. 2.3 Soil Gas Sampling Soil gas samples were collected from temporary soil gas probes installed adjacent to wells MW-5 and MW-7. These wells are located in the central portion of the Site where the highest groundwater concentration have generally been observed. The location of the soil gas probes is shown on Figure 6. The soil gas probes were installed within the vadose zone at a depth ranging from approximately 3.5 to 4.5 feet bgs (approximately 1.5 feet above the measured groundwater level at the time of the probe installation) using a direct push drill rig. After installation, soil gas samples were collected from the probes for VOCs analysis via evacuated stainless-steel summa canisters using the analytical methods specified in Section 2.4. The soil gas probe installation and soil gas sampling were performed in accordance with the methods and procedures presented in the QAPP (SOP-009 Paxton SCR 6 and SOP-010). Prior to sampling, the following leak checks were performed to ensure that representative samples were obtained: Summa check; Vacuum shut-in leak test; and Purging, field screening, and helium shroud leak test. All samples were collected at a flow rate of approximately 200 milliliters per min (mL/min) using a laboratory supplied flow controller. Completed soil gas probe construction and sampling logs are included in Appendix B. 2.4 Laboratory Analytical Methods All samples were submitted to Pace Analytical Laboratory, a National Environmental Laboratory Accreditation Conference accredited and Utah certified analytical laboratory. Analyses were completed using the EPA approved methods presented below, as applicable: Soil/Groundwater Samples RCRA metals by Methods 6010B/7470A/7471A TPH -DRO/GRO by Method 8015 Oil and Grease by Method 1664A/9071 VOCs by Method 8260B Soil Gas Samples VOCs by Method TO-15 All analyses were performed in accordance with method specific requirements specified in the QAPP using standard analytical turnaround times. All reports were completed as Level III reports. Completed laboratory reports are provided in Appendix C. 2.5 Quality Control Sampling Quality control samples included field duplicate, matrix spike/matrix spike duplicate and equipment blank and trip blank samples (VOCs only). Quality control samples were collected at the frequency specified in the QAPP. Data validation is discussed in Section 4.0. 2.6 Sample Handling and Custody 2.6.1 Sample Containers and Labeling Upon collection, all samples were placed into laboratory-supplied sample containers and labeled with a unique identification. Clean, disposable, nitrile gloves were worn during sample handling to prevent cross-contamination between samples. Paxton SCR 7 2.6.2 Sample Packaging After labeling, each sample was placed in a cooler containing wet ice to reduce the sample temperature to approximately 4 (±2) °C during storage and transport to the laboratory. The samples were packaged and shipped in general accordance with laboratory specified procedures. 2.6.3 Chain of Custody A Chain of Custody (CoC) form was completed to track sample control and possession from the time of collection through laboratory analysis. The analyses to be performed were designated on the CoC form, including the quantity and types of containers that comprised each sample and other pertinent sample information. One CoC form accompanied each sample shipment. 2.7 Decontamination All non-disposable sampling equipment was decontaminated prior to use and in-between sample locations in accordance with the decontamination procedures specified in the QAPP (SOP-12). Non-disposable sampling equipment was limited to the stainless-steel hand auger used during the soil sampling activities. Equipment blank samples were collected during soil sampling to evaluate the effectiveness of the decontamination procedures. Results of the equipment blank samples were evaluated as part of the data validation (see Section 4.0). No significant detections were reported in the equipment blank samples indicating that the decontamination procedures were generally effective at limiting potential cross contamination. 2.8 Investigation Derived Waste Management Generated investigation derived waste (IDW) consisted of consumable field supplies (paper towels, miscellaneous paper products, etc.), disposable PPE items (nitrile gloves), purge water and decontamination water. Consumable field supplies and PPE were collected and disposed of as non- hazardous solid waste. Purge water and decontamination water were collected containerized in 55- gallon drum, labeled, and temporarily staged at the Site for future disposal pending characterization. Approximately 25 gallons of purge/decon water was generated during the site characterization activities. 2.9 Screening Levels Screening levels applied to the site characterization data include the most recent EPA residential RSLs, EPA MCLs, EPA residential Vapor Intrusion Screening Levels (VISLs), and/or DERR ISLs, as relevant and appropriate based on media type. Paxton SCR 8 3. INVESTIGATION FINDINGS The following section present the analytical results for soil, groundwater and soil gas samples collected as part of the site characterization activities, which are summarized on Tables 1, 2 and 3, respectively. 3.1 Soil Sample Results Soil sample locations and depths are indicated on Figure 4. Exceedances of site screening levels (both sample locations and depths) are described below. 3.1.1 Metals Exceedances for arsenic, lead and/or cadmium were observed above the EPA residential RSLs in all of the soil samples. The maximum detected arsenic, cadmium and lead concentrations were reported at 34.6 mg/kg, 8.79 mg/kg and 714 mg/kg, respectively. Cadmium exceedances were identified at one sample location (S-4) from 0 to 6 inches bgs. Lead exceedances were observed in seven sample locations (S-1, S-3, S-4, S-6, S-7, S-15, and SS-1) at depths of 0 to 6 inches and/or 6 to 12 inches bgs. No lead exceedances were observed at deeper depths, with the exception of one sample (S-6) from 12 to 18 inches bgs. Arsenic concentrations exceeded the screening levels at all of the sample locations. Arsenic concentrations were generally observed to decrease with depth. It is noted that naturally occurring concentrations of arsenic are regularly observed exceeding the screening levels in Salt Lake Valley. 3.1.2 Petroleum Constituents Exceedances for oil and grease were detected above the DERR ISL of 1,000 mg/kg at seven of the 16 sample locations (S-4, S-5, S-6, S-7, S-11, S-12 and SS-1), with reported concentrations ranging from 1,250 mg/kg to 11,500 mg/kg. Additionally, TPH-DRO was also detected above the DERR ISL of 500 mg/kg at sample locations S-5 and S-7 (TPH-DRO concentrations of 542 mg/kg and 1,180 mg/kg, respectively). No exceedances for TPH-GRO were detected in any of the sample locations. All of the exceedances were observed in the samples collected from 0-6 inches, except for location SS-1 where the exceedance was observed in the 6-12 inch bgs interval. Deeper samples (from 6-12 inches or 12-18 inches) were collected from all of the locations where exceedances were observed, except for locations S-5 and S-11 (deeper samples were not proposed for these locations). No DERR ISL exceedances were identified in the deeper samples. Similar to the observed detections of metals, the data suggests that while detections of oil and grease and TPH- DRO in soil are present in select areas, the impacts do not appear to extend below 12 inches in depth and in most cases are only present in the upper 6 inches. Figure 4a depicts the estimated extent of screening level exceedances in soil for petroleum hydrocarbons (e.g., oil and grease, TPH-DRO, and/or TPG-GRO). 3.1.3 VOCs Trace detections of one or more VOCs were detected at all 16 sample locations. However, all of the reported detections were below EPA residential RSLs for soil indicating that significant Paxton SCR 9 concentrations of VOCs are not present in shallow soil. This is consistent with the samples collected during the initial investigations, which also did not identify significant VOCs in soil. 3.2 Groundwater Groundwater sample locations are indicated on Figure 5. Exceedances of site screening levels are described below. 3.2.1 Petroleum Constituents TPH-DRO and TPH-GRO were detected in wells MW-2 and MW-7, respectively, at concentrations that exceed the DERR ISLs of 1 mg/L for these parameters. The reported TPH- DRO concentration in MW-2 was 1.08 mg/L. The reported TPH-GRO concentration at MW-7 was 3.28 mg/L. At all other locations, the TPH-DRO and TPH-GRO concentrations were either non- detect or below the DERR ISLs. Figure 5a depicts the estimated extent of screening level exceedances in groundwater for petroleum hydrocarbons (e.g., TPH-DRO and/or TPG-GRO). Oil and grease was detected in one well location (MW-1) at a reported concentration of 1.68 mg/L. The reported concentration is significantly below the DERR ISL for this parameter of 10 mg/L. No other detections for oil and grease were reported in the samples. 3.2.2 VOCs Samples from wells MW-2, MW-3, MW-4, MW-5, MW-7 and MW-8 showed detections for one or more VOCs above the EPA MCLs or RSLs (the RSLs were only applied if an MCL has not been established for a detected compound). VOCs detected above the MCLs/RSLs include 1,1- dichloroethane, 1,1-dichloroethene, cis-1,2-dichloroethene, 1,2-dichloropane, and vinyl chloride. The VOCs that were observed to exceed the MCLs/RSLs and the range of concentrations that were detected are generally similar to the previous groundwater sample data collected as part of the initial investigation activities (AGEC 2023a and AGEC 2023b). VOCs observed exceeding the MCL/RSLs were also observed to exceed the EPA groundwater VISLs in one or more locations, indicating a potential for vapor intrusion from groundwater to soil gas. Samples collected from wells MW-9 and MW-10, which are screened at deeper intervals than the other Site wells, did not show any exceedances of relevant screening levels. The only reported detection in these wells was for cis-1,2-dichloroethene, which was observed at concentrations several orders of magnitude below the MCL and VISL for this compound. Figure 5b depicts the estimated extent of screening level exceedances in groundwater for VOCs. 3.3 Soil Gas The samples collected from the soil gas probes showed reported detections for benzene, chloroform, 1,1-dichloroethane, cis-1,2-dichloroethene, tetrachloroethene, trichloroethene and vinyl chloride at one or both locations above the EPA VISLs for sub-slab and near source soil gas. Total VOC concentrations ranged from approximately 6,017 μg/m3 in SV-1 to 9,996 μg/m3 in SV- 2, with the highest concentrations generally observed for 1,1-dichloroethane, cis-1,2- dichloroethene, tetrachloroethene and trichloroethene in both samples. The results indicate that Paxton SCR 10 elevated levels of soil gas are present that would potentially require mitigation for the development of residential structures on the Site. 3.4 Water Level Measurements In conjunction with the groundwater sampling activities water level measurements were made at the existing well locations. The water level measurements are summarized on Table 4. A groundwater contour map developed from the water level measurements is provided as Figure 7. Groundwater was observed to range from approximately 4.5 to 6.0 feet below ground surface across the Site during the groundwater sampling activities. As shown on Figure 7, the groundwater gradient is very flat with approximately 0.3 feet of change across the site or 0.0013 ft/ft. The groundwater flow direction also varies but is generally west to northwest depending on location with a localized area of flow to the north in the southwest corner of the Site. The overall groundwater flow direction is generally consistent with the expected regional groundwater flow direction, which also assumed to be to the west based on topography. Given the shallow depth and the flat gradient it is likely that shallow groundwater is influenced significantly by surface precipitation and infiltration and the groundwater depth and flow direction may fluctuate periodically with these changes. Paxton SCR 11 4. DATA VALIDATION All laboratory data were validated by Geosyntec’s internal data validation team in accordance with the procedures and methods specified in the QAPP. The data validation reports are included in Appendix D. The data validation included a review of project specific and laboratory quality control samples and each analytical test to verify the rests and confirm that no systematic laboratory issues were occurring for the required analyses. The data were qualified, where necessary, in accordance with criteria established in the QAPP. Based on the results of the validation, all of the data, as qualified, were determined to be usable for supporting project objectives and decision-making purposes, except as noted below. The non-detect VOC results from the groundwater sample collected from well MW-10 were qualified as “rejected” due to a holding time issue. MW-10 is a deep well screened from 28 to 33 feet bgs. Sample MW-10 did not meet the method criteria of a pH ≤ 2 (the pH was not determined until the sample was analyzed by the lab in accordance with standard laboratory procedure). Therefore, the sample was considered unpreserved. The holding times for the VOCs analysis of preserved water samples is 14 days from sample collection to analysis. The holding times for the VOCs analysis of unpreserved water samples is 7 days from sample collection to analysis. Due to this issue, the sample was analyzed approximately one day outside of the hold time (approximately 8 days after collection). The only reported analyte in the sample from MW-10 was a trace detection of cis-1,2- dichloroethene (0.000166 J mg/L), which was detected at a level below the reporting limit (note, the reported detection was not rejected). While non-detect results in the sample from MW-10, were rejected it is noted that a comparison of the previous sample collected from this location during the initial investigation by AGEC (AGEC 2023b) is consistent with the current result, showing primarily non-detect results. Further, previous data and the current results from the other deep well on the Site (MW-9) have not indicated that there are elevated levels of VOCs in deeper groundwater at the Site consistent with the current result from MW-10. Based on this, while the non-detect results are qualified as “rejected,” they are not considered to significantly hinder the overall usability of the data or affect the overall conclusions of the SCR report and therefore additional action to address this issue is not recommended. Paxton SCR 12 5. FINDINGS AND CONCLUSIONS Based on the completed Site characterization activities the following key findings and conclusions are noted: Metals (arsenic, lead and/or cadmium) and/or petroleum constituents (oil and grease and/or TPH-DRO) were observed at all of the 16 soil sample locations (above relevant screening levels.. With the exception of arsenic, observed exceedances were generally confined within the upper 12 inches of soil, with only one location (S-6) showing potential elevated levels of lead from the deeper sample collected from 12-18 inches bgs. Naturally occurring concentrations of arsenic that exceed the screening levels are regularly observed in the Salt Lake City Valley. No VOCs were detected in any of the soil samples above relevant screening levels. VOCs and/or petroleum constituents (TPH-GRO/DRO) were detected above screening levels in the groundwater samples collected from monitoring wells MW-2, MW-3, MW-4, MW-5, MW-7 and MW-8. Additionally, the VOCs that were observed exceeding the MCL/RSLs were also observed to exceed the EPA VISLs for groundwater in one or more locations indicating a potential for vapor intrusion. All of the groundwater exceedances were observed in the uppermost saturated groundwater zone. No exceedances of relevant screening levels were detected in the two wells that are screened at deeper intervals within the Site (wells MW-9 and MW-10), which is consistent with previous investigation data. Soil data collected from the Site has shown trace detections of VOCs, but has not identified a significant on-site source for the observed detections in groundwater. No significant on- site potential sources of VOCs were identified during this or previous investigations and the available data suggests that the observed detections are potentially related to the adjacent RETEP site or another off-site source. Both soil gas samples collected from the Site showed VOCs levels above the EPA VISLs for near source sub-slab and near source soil gas. The detection of elevated levels of soil gas is consistent with observed groundwater concentrations which also exceed the VISLs. Groundwater elevation data collected during the groundwater monitoring activities indicates that a relatively flat gradient exists at the Site and that the overall groundwater flow direction is generally to the west-northwest, which is consistent with the expected regional groundwater flow direction and previous Site data. Groundwater is present at depths ranging from approximately 4.5 to 6.0 feet bgs. Given the shallow depth and the flat gradient, it is likely that shallow groundwater is influenced significantly by surface precipitation and infiltration and the groundwater flow direction and depth may fluctuate with these changes. Paxton will prepare a remedial action plan (RAP) to address the identified impacts from the Site characterization activities and the previous assessments. In addition to addressing the identified impacts, the RAP will also describe the removal of the hydraulic lifts and building foundations Paxton SCR 13 that are present within the Site. The RAP will be submitted to the DERR for review, public comment, and approval prior to initiation of work. Paxton SCR 14 6. REFERENCES AGEC. 2023a.

SDG Sample Delivery Group. Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Slope Slope of calibration curve. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Wavelength Wavelength of parameter. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT L1757957 11/22/24 14:29 525 of 530 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT L1757957 11/22/24 14:34 525 of 530 GLOSSARY OF TERMS Qualifier Description P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT L1757957 11/22/24 14:29 526 of 530 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT L1757957 11/22/24 14:34 526 of 530 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT L1757957 11/22/24 14:29 527 of 530 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT L1757957 11/22/24 14:34 527 of 530 ANALYTICAL REPORT October 18, 2024 Geosyntec Consultants - UT Sample Delivery Group:L1784578 Samples Received:10/02/2024 Project Number:SLC1091 Description:Paxton Ave. Report To:Brian Smith 215 South State Street Suite 500 Salt Lake City, UT 84111 Entire Report Reviewed By: October 18, 2024 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions COD Coefficient of Determination. Corr.Correlation Coefficient. (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. Incpt Intercept. Mass Mass of parameter. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. RRF Relative Response Factor. RT Retention Time. SDG Sample Delivery Group. Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Slope Slope of calibration curve. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Wavelength Wavelength of parameter. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1784578 10/18/24 11:02 521 of 526 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1784578 10/18/24 11:14 521 of 526 GLOSSARY OF TERMS Qualifier Description J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate matrix interference. P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit. Q Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations should be considered minimum values. V The sample concentration is too high to evaluate accurate spike recoveries. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1784578 10/18/24 11:02 522 of 526 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1784578 10/18/24 11:14 522 of 526 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1784578 10/18/24 11:02 523 of 526 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1784578 10/18/24 11:14 523 of 526 ANALYTICAL REPORT November 05, 2024 Geosyntec Consultants - UT Sample Delivery Group:L1791693 Samples Received:10/02/2024 Project Number:SLC1091 Description:Paxton Ave. Report To:Brian Smith 215 South State Street Suite 500 Salt Lake City, UT 84111 Entire Report Reviewed By: November 05, 2024 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions Corr.Correlation Coefficient. (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. Incpt Intercept. Mass Mass of parameter. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Slope Slope of calibration curve. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Wavelength Wavelength of parameter. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J3 The associated batch QC was outside the established quality control range for precision. V The sample concentration is too high to evaluate accurate spike recoveries. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1791693 11/05/24 10:53 44 of 47 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1791693 11/05/24 11:00 44 of 47 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1791693 11/05/24 10:53 45 of 47 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Geosyntec Consultants - UT SLC1091 L1791693 11/05/24 11:00 45 of 47 ANALYTICAL REPORT August 05, 2024 Geosyntec Consultants - UT Sample Delivery Group:L1758896 Samples Received:07/20/2024 Project Number: Description:Paxton Report To:Brian Smith 215 South State Street Suite 500 Salt Lake City, UT 84111 Entire Report Reviewed By: August 05, 2024 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

UT L1758896 08/05/24 14:07 205 of 210 GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions COD Coefficient of Determination. Mass Mass of parameter. MDL Method Detection Limit. RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. RRF Relative Response Factor. RT Retention Time. SDG Sample Delivery Group. Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Wavelength Wavelength of parameter. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions COD Coefficient of Determination. Mass Mass of parameter. MDL Method Detection Limit. RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. RRF Relative Response Factor. RT Retention Time. SDG Sample Delivery Group. Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.

Five method blanks were reported for oil and grease (batches WG2330367, WG2330146, WG2380187, WG2378003, and WG2378468). Oil and grease were not detected in the method blanks at or above the MDLs. 1.4 Matrix Spike (MS)/Matrix Spike Duplicate (MSD) MS/MSDs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). Three sample specific MS/MSD pairs and sample specific MS were reported using samples S-3 (0-6), S-32 (0-6) and S-10 (0-6) and on MS was reported using sample EB-1-071624. The recovery and RPD results were within the laboratory specified acceptance criteria, with the following exceptions. L1757957: The recovery of oil and grease in the MSD of sample S-3 (0-6) was low and outside of the laboratory specified acceptance criteria. The RPD of oil and grease between the MS and MSD of sample S-3 (0-6) was high and outside of the laboratory specified acceptance criteria. Therefore, the oil and grease data of sample S-3 (0-6) was J qualified as estimated. L1784578: The recoveries of oil and grease in the MS/MSD of sample S-32 (0-6) were low and outside of the laboratory specified acceptance criteria. Therefore, the oil and grease data of sample S-32 (0-6) was J- qualified as estimated with low bias. A batch MS was analyzed with batch WG2380187. Since this was batch QC, the results were not qualified.

The RPD results were within the laboratory specified acceptance criteria, with the following exceptions. L1757957: The RPD of oil and grease in the laboratory duplicate pair of sample S-3 (0-6) was outside of the laboratory specified acceptance criteria. Since the oil and grease concentration for sample S-3 (0-6) was less than five times the RDL and the difference between the laboratory duplicate and original sample results was less than the RL, no qualifications were applied to the data. L1784578: The RPD of oil and grease in the laboratory duplicate pair of sample S-32 (0-6) was outside of the laboratory specified acceptance criteria. Since the oil and grease concentration for sample S-32 (0-6) was less than five times the RDL and the difference between the laboratory duplicate and original sample results was less than the RDL, no qualifications were applied to the data. L1784578: The RPD of oil and grease in the laboratory duplicate pair of sample S-10 (0-6) was outside of the laboratory specified acceptance criteria. Therefore, the oil and grease data of sample S-10 (0-6) was J qualified as estimated.

The holding times were met for the sample analyses. 3.3 Method Blank Method blanks were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). Seven method blanks were reported (batches WG2326410, WG2326543, WG2327640, WG2376546, WG2376598, WG2378117 and WG2393511). Metals were not detected in the method blanks at or above the MDLs, with the following exceptions. L1757957: Silver (0.766 mg/kg) was detected at an estimated concentration greater than or equal to the MDL and less than the RDL in the method blank of batch WG2326410. Therefore, the estimated silver data in the associated samples were qualified U as non-detect and reported at the RDL. L1784578: Silver (0.184 mg/kg) was detected at an estimated concentration greater than or equal to the MDL and less than the RDL in the method blank of batch WG2376598. Therefore, the estimated silver data were qualified U as non-detect and reported at the RDL. L1757957: Chromium (0.00143 mg/L) was detected at an estimated concentration greater than or equal to the MDL and less than the RDL in the method blank of batch WG2327640. Therefore, the estimated chromium data of the associated sample was U qualified as non-detect and reported at the RDL. L1784578: Arsenic (0.761 mg/kg) was detected at an estimated concentration greater than or equal to the MDL and less than the RDL in the method blank of batch WG2376546. Since arsenic was detected at a concentration greater than ten times the method blank concentration in the associated sample, no qualifications were applied to the arsenic data.

The results are considered valid; the analytical completeness defined as the ratio of the number of valid analytical results (valid analytical results include values qualified as estimated) to the total number of analytical results requested on samples submitted for analysis, for the sample set is 100%. 4.2 Holding Times The holding times for the TPH low fraction analysis of water and soil samples are 14 days from collection to analysis. The holding times were met for the sample analyses. 4.3 Method Blank Method blanks were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). Eleven method blanks were reported (batches WG2327971, WG2328825, WG2329459, WG2329829, WG2329941, WG2330767, WG2330774, WG2377829, WG2377924, WG2378256, and WG2378697). TPH low fraction was not detected in the method blanks at or above the MDLs, with the following exceptions. L1757957, l1791693 and L1784578: TPH low fraction was detected at estimated concentrations greater than or equal to the MDLs and less than the RDLs in the method blanks of batches: WG2328825 (0.657 mg/kg), WG2329459 (1.06 mg/kg), WG2329829 (0.738 mg/kg), WG2330767 (2.01 mg/kg), WG2330774 (2.01 mg/kg), WG2377829 (0.675 mg/kg), WG2377924 (0.846 mg/kg), and WG2378256 (0.800 mg/kg). Therefore, based on technical and professional judgement, the TPH low fraction data of the associated samples with estimated concentrations greater than or equal to the MDL and less than the RDL were U qualified as non-detect and reported at the RDL. The TPH low fraction data in the associated samples with concentrations greater than the RDL, or less than the MDL were not qualified.

Isopropylbenzene was detected at an estimated concentration greater than or equal to the MDL and less than the RDL in the field duplicate sample S-30 (6-12), but isopropylbenzene was detected above the RDL in sample S-3 (6-12), resulting in a non-calculable RPD. Therefore, the isopropylbenzene data of field duplicate S-30 (6-12) and original sample S-3 (6-12) were J qualified as estimated. The RPDs of benzene, ethylbenzene, toluene, and total xylenes between the field duplicate S-31 (0-6) and original sample S-4 (0-6) were high and outside of the laboratory specified acceptance criteria. Therefore, the benzene, ethylbenzene, toluene, and total xylenes data of field duplicate S- 31 (0-6) and original sample S-4 (0-6) were J qualified as estimated. Isopropylbenzene and methylene chloride were detected at estimated concentrations greater than or equal to the MDLs and less than the RDLs in the field duplicate sample S-31 (0-6), but were not detected at or above the MDLs in the original sample S-4 (0-6); resulting in a non-calculable RPD. Therefore, the non-detect isopropylbenzene and methylene chloride data were UJ qualified as estimated non detect, and the detected isopropyl and methylene chloride data were J qualified as estimated. Ethylbenzene, p-isopropyltoluene, methylene chloride, and total xylenes were detected at estimated concentrations greater than or equal to the MDLs and less than the RDLs in the field duplicate sample S-32 (0-6), but were not detected at or above the MDLs in the original sample S- 13 (0-6); resulting in a non-calculable RPD.

Five method blanks were reported (batches WG2330427, WG2331405, WG2380823, WG2380134 and WG2380815). TPH high fraction was not detected in the method blanks at or above the MDL, with the following exceptions. TPH high fraction (0.0252 mg/L) was detected at an estimated concentration greater than or equal to the MDL and less than the RDL in the method blank of batch WG2330427. Therefore, based on technical and professional judgement, the TPH high fraction data of sample EB-1-071624 was qualified U as non-detect and reported at the RDL.

Accuracy and precision were assessed using an LCS/LCSD pair for batches WG2330427 and WG2380823. 6.5 Laboratory Control Sample LCSs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). LCS/LCSD pairs and LCSs were reported. The recovery and RPD results were within the laboratory specified acceptance criteria. 6.6 Surrogates The surrogate recoveries were within the laboratory specified acceptance criteria, with the following exception. The recovery of the surrogate o-Terphenyl in the MS and MSD of sample S-10 (0-6) were flagged ‘J7’ by the laboratory indicating that the surrogate recoveries could not be used for control limit evaluation due to dilution. Due to technical and professional judgement, no qualifications were applied to the surrogate data of the MS/MSD of sample S-10 (0-6). 6.7 Equipment Blank Two equipment blanks, EB-1-071624 and EB-93024, were collected with the sample set; however, they were not analyzed for TPH high fraction, with the following exception. L1757957: TPH high fraction (0.0688 mg/L) was detected in EB-1-071624 at an estimated concentration greater than the MDL and less than the RDL. 6.8 Field Duplicate Three field duplicates were collected with the sample set: S-30 (6-12), S-31 (0-6), and S-32 (0-6). Acceptable precision (RPD<50%) were demonstrated between the field duplicates and the original samples S-3 (6-12), S-4 (0-6), and S-13 (0-6) respectively, with the following exceptions. TPH high fraction was detected at an estimated concentration greater than or equal to the MDL and less than the RDL in the field duplicate sample S-32 (0-6), but was detected above the RDL in sample S-13 (0-6); resulting in a non-calculable RPD.

J The analyte was positively identified; the associated numerical value is the approximate concentration of the analyte in the sample. J+ The analyte was positively identified; however, the associated numerical value is likely to be higher than the concentration of the analyte in the sample due to positive bias of associated QC or calibration data or attributable to matrix interference. J- The analyte was positively identified; however, the associated numerical value is likely to be lower than the concentration of the analyte in the sample due to negative bias of associated QC or calibration data or attributable to matrix interference. UJ The analyte was not detected above the reported sample quantitation limit. However, the reported quantitation limit is approximate and may or may not represent the actual limit of quantitation necessary to accurately and precisely measure the analyte in the sample. R The sample results are rejected due to serious deficiencies in the ability to analyze the sample and meet quality control criteria. The presence or absence of the analyte cannot be verified.

Overall Assessment Holding Times Method Blank Matrix Spike/Matrix Spike Duplicate Laboratory Control Sample ⊗ Field Duplicate Sensitivity Electronic Data Deliverable Review 1.1 Overall Assessment The oil and grease data reported in this data set are considered usable for supporting project objectives. The analytical completeness, defined as the ratio of the number of valid analytical results (valid analytical results include values qualified as estimated) to the total number of analytical results requested on samples submitted for this analysis, for the data set is 100%. 1.2 Holding Times The holding time for oil and grease analysis of a preserved water sample is 28 days from sample collection to analysis. The holding times were met for the sample analyses. 1.3 Method Blank Method blanks were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One method blank was reported for oil and grease by US EPA method 1664A (batch WG2331265). Oil and grease were not detected in the method blank at or above the MDL. 1.4 Matrix Spike/Matrix Spike Duplicate MS/MSDs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One sample specific MS/MSD pair was reported using sample MW- 2. The recovery and relative percent difference (RPD) results were within the laboratory specified acceptance criteria, with the following exceptions. The recovery of oil and grease in the MS of sample MW-2 was high and outside of the laboratory specified acceptance criteria. Since oil and grease was not detected in sample MW-2 at a concentration greater than the MDL, no qualifications were applied to the data.

One LCS/LCS duplicate (LCSD) pair was reported for batch WG2331265. The recovery and RPD results were within the laboratory specified acceptance criteria. 1.6 Field Duplicate One field duplicate was collected with the sample set, MW-25. Acceptable precision (RPD<30%) was not demonstrated between the field duplicate and the original sample MW-1. Oil and grease were not detected in the original sample MW-1 at or above the MDL. Oil and grease were detected at an estimated concentration greater than or equal to the MDL and less than the reporting detection limit (RDL) in the field duplicate sample MW-25, resulting in a non-calculable RPD between MW-1 and MW-25. Therefore, based on technical and professional judgement the oil and grease data were J or UJ qualified as estimated or estimated non-detect.

The results are considered valid; the analytical completeness defined as the ratio of the number of valid analytical results (valid analytical results include values qualified as estimated) to the total number of analytical results requested on samples submitted for analysis, for the sample set is 100%. 2.1.2 Analysis Anomaly The pH’s of samples MW-2, MW-10, and MW-9 did not meet the method criteria of pHs ≤ 2. Therefore, the samples were considered unpreserved. 2.2 Holding Time The holding time for TPH low fraction analysis of a preserved water sample is 14 days from sample collection to analysis. The holding time for TPH low fraction analysis of an unpreserved water sample is 7 days from sample collection to analysis. The holding times were met for the sample analyses, with the following exception. Sample MW-2 was analyzed outside the holding time of an unpreserved sample. Therefore, the TPH low fraction concentration for sample MW-2 was J qualified as estimated.

One method blank was reported for TPH low fraction by US EPA method 8015D/GRO (batch WG2329885). TPH low fraction (0.0744 mg/L) was detected in the method blank at an estimated concentration greater than or equal to the MDL and less than the RDL. Therefore, based on technical and professional judgement, the TPH low fraction data with estimated recoveries greater than or equal to the MDL and less than the RDL were U qualified as non-detect and reported at the RDL. In addition, the TPH low fraction concentrations greater the RDL and less than five times the method blank concentration were J+ qualified as estimated with high bias. The TPH low fraction data with concentrations greater than five times the method blank concentration were not qualified. Since the TPH low fraction concentration for sample MW-2 was also qualified for holding time exceedance and MS/MSD RPD outside criteria, the final qualification was J qualified as estimated.

Three method blanks were reported (batches WG2330260, WG2330346 and WG2332276). VOCs were not detected in the method blanks at or above the MDL. 3.4 Matrix Spike/Matrix Spike Duplicate One sample specific MS/MSD pair was reported using sample MW-2. The recovery and RPD results were within the laboratory specified acceptance criteria, with the following exceptions. Cis-1,2-dichloroethene was flagged ‘V’ by the laboratory indicating the concentration of cis-1,2- dichloroethene in the original sample, MW-2, was greater than the spike concentration. Therefore, based on technical and professional judgement, no qualifications were applied to the data. The recoveries of acrolein, carbon tetrachloride, chloroethane, 1,2-dichloroethane, 1,1,2- trichlorotrifluoroethane, and trichlorofluoromethane in the MS/MSD of sample MW-2 were high and outside of the laboratory specified acceptance criteria. Since these analytes were not detected in sample MW-2 at concentrations greater than or equal to the MDLs, no qualifications were applied to the data. The recovery of methylene chloride in the MSD of sample MW-2 was high and outside of the laboratory specified acceptance criteria. Since methylene chloride was not detected in sample MW-2 at concentrations greater than or equal to the MDL, no qualifications were applied to the data. Sample specific MS/MSDs were not reported for batches WG2330346 and WG2332276. Accuracy and precision were assessed using an LCS/LCSD pair for batch WG2330346. Precision was assessed using an LCS for batch WG2332276. 3.5 Laboratory Control Sample LCSs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One LCS/LCSD pair and two LCSs were reported. The recovery and RPD results were within the laboratory specified acceptance criteria, with the following exceptions. The recovery of acrolein in the LCS of batch WG2330260 was high and outside of the laboratory specified acceptance criteria. Since acrolein was not detected in the associated samples at concentrations greater than or equal to the MDL, no qualifications were applied to the data. Paxton Data Validation 26 November 2024 Page 12 DVR L1758896 R3.docx Final Review: K Henderson 11/26/2024 The RPD of vinyl chloride between the LCS and LCSD of batch WG2330346 was high and outside of the laboratory specified acceptance criteria. Since vinyl chloride was not detected in the associated samples at concentrations greater than or equal to the MDL, no qualifications were applied to the data. 3.6 Surrogates The surrogate recoveries were within the laboratory specified acceptance criteria. 3.7 Trip Blank One trip blank, TRIP BLANK, accompanied the sample shipment. VOCs were not detected in the trip blank at or above the MDLs. 3.8 Field Duplicate One field duplicate was collected with the sample set, MW-25. Acceptable precision (RPD<30%) was demonstrated between the field duplicate and the original sample MW-1. 3.9 Sensitivity The samples were evaluated to the MDL. Elevated non-detect results were not reported. 3.10 Electronic Data Deliverable Review The results and sample IDs in the EDD were reviewed against the information provided by the associated level II report at a minimum of 20% as part of the data validation process. It was noted the laboratory reported included both the MDLs and RDLs, however, only the RDLs were included in the EDD. No other discrepancies were identified between the level II report and the EDD. 4.0 Total Petroleum Hydrocarbons High Fraction The samples were analyzed for TPH high fraction by US EPA methods 3511/8015 3510C.

The results are considered valid; the analytical completeness defined as the ratio of the number of valid analytical results (valid analytical results include values qualified as estimated) to the total number of analytical results requested on samples submitted for analysis, for the sample set is 100%. 4.2 Holding Times The holding times for the TPH high fraction analysis of a water sample are 7 days from sample collection to sample extraction and 40 days from sample extraction to analysis. The holding times were met for the sample analyses. 4.3 Method Blank Method blanks were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One method blank was reported (batch WG2332252). TPH high fraction were not detected in the method blank at or above the MDL. 4.4 Matrix Spike/Matrix Spike Duplicate MS/MSDs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One sample specific MS/MSD pair was reported using sample MW- 2. The recovery and RPD results were within the laboratory specified acceptance criteria. 4.5 Laboratory Control Sample LCSs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples).

However, since the spike recovery was within the laboratory specified acceptance criteria, and due to technical and professional judgement, no qualifications were applied to the data. O-Terphenyl recovered low and outside of the laboratory specified acceptance criteria in sample MW-9. Therefore, based on technical and professional judgement, the detected TPH high fraction data of sample MW-9 was J- qualified as estimated with low bias.

No preservation issues were noted by the laboratory. The laboratory reported results for the analytical method(s) requested for each sample on the COC. The data validation report was revised on November 26, 2024, to make edits. 1.0 Volatile Organic Compounds The samples were analyzed for VOCs by US EPA method TO-15. The areas of data review are listed below. A leading check mark () indicates an area of review in which the data were acceptable. A preceding crossed circle (⊗) signifies areas where issues were raised during the validation review and should be considered to determine any impact on data quality and usability.

The analytical completeness, defined as the ratio of the number of valid analytical results (valid analytical results include values qualified as estimated) to the total number of analytical results requested on samples submitted for this analysis, for the data set is 100%. 1.2 Holding Times The holding time for the VOCs analysis of a soil vapor sample is 30 days from sample collection to analysis. The holding times were met for the sample analyses. Paxton Data Validation 22 November 2024 Page 3 DVR L1784259 R1.docx Final Review: K Henderson 11/26/2024 1.3 Method Blank Method blanks were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). Two method blanks were reported (batches WG2374030 and WG2376939). VOCs were not detected in the method blanks at or above the method detection limits (MDLs), with the following exceptions. Propene and TPH were detected in the method blank of batch WG2374030 at estimated concentrations greater than or equal to the MDLs and less than the reported detection limits (RDLs). However, since propene was not detected in the associated samples at concentrations greater than or equal to the MDL, no qualifications were applied to the propene data. Since the associated samples had detected concentrations of TPH greater than ten times the concentration of TPH in the method blank, no qualifications were applied to the TPH data. 1.4 Laboratory Control Sample (LCS) LCSs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). Two LCS/LCS duplicate (LCSD) pairs were reported for batches WG2374030 and WG2376939. The recovery and relative percent difference (RPD) results were within the laboratory specified acceptance criteria. 1.5 Surrogates The surrogate recoveries were within the laboratory specified acceptance criteria. 1.6 Field Duplicate One field duplicate was collected with the sample set, SV-20. Acceptable precision (RPD<30%) was demonstrated between the field duplicate and the original sample SV-2, with the following exceptions. The RPDs of acetone, 1,1-dichloroethane, cis-1,2-dichloroethene, trans-1,2-dichloroethene, ethanol, methylene chloride, tetrachloroethene, trichloroethene, and 1,2,4-trimethylbenzene between the field duplicate sample SV-20 and original sample SV-2 were high and outside of the laboratory specified acceptance criteria. Therefore, the data of these analytes were J qualified as estimated in the field duplicate sample SV-20 and original sample SV-2. Carbon disulfide was not detected at or above the RDL in the field duplicate sample SV-20 but was detected at a concentration greater than the RDL in the original sample SV-2, resulting in a non-calculable RPD. Therefore, the carbon disulfide data of the field duplicate sample SV-20 and original sample SV-2 were UJ or J qualified as estimated non-detect or estimated. Paxton Data Validation 22 November 2024 Page 4 DVR L1784259 R1.docx Final Review: K Henderson 11/26/2024 N-Hexane was not detected at or above the RDL in the field duplicate sample SV-20 but was detected at a concentration greater than the RDL in the original sample SV-2, resulting in a non- calculable RPD. Therefore, the n-hexane data of the field duplicate sample SV-20 and original sample SV-2 were UJ or J qualified as estimated non-detect or estimated.

Paxton Data Validation 26 November 2024 Page 3 DVR L1758896 R3.docx Final Review: K Henderson 11/26/2024 The areas of data review are listed below. A leading check mark () indicates an area of review in which the data were acceptable. A preceding crossed circle (⊗) signifies areas where issues were raised during the validation review and should be considered to determine any impact on data quality and usability. Overall Assessment Holding Times Method Blank Matrix Spike/Matrix Spike Duplicate Laboratory Control Sample ⊗ Field Duplicate Sensitivity Electronic Data Deliverable Review 1.1 Overall Assessment The oil and grease data reported in this data set are considered usable for supporting project objectives. The analytical completeness, defined as the ratio of the number of valid analytical results (valid analytical results include values qualified as estimated) to the total number of analytical results requested on samples submitted for this analysis, for the data set is 100%. 1.2 Holding Times The holding time for oil and grease analysis of a preserved water sample is 28 days from sample collection to analysis. The holding times were met for the sample analyses. 1.3 Method Blank Method blanks were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One method blank was reported for oil and grease by US EPA method 1664A (batch WG2331265). Oil and grease were not detected in the method blank at or above the MDL. 1.4 Matrix Spike/Matrix Spike Duplicate MS/MSDs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One sample specific MS/MSD pair was reported using sample MW- 2. The recovery and relative percent difference (RPD) results were within the laboratory specified acceptance criteria, with the following exceptions. The recovery of oil and grease in the MS of sample MW-2 was high and outside of the laboratory specified acceptance criteria. Since oil and grease was not detected in sample MW-2 at a concentration greater than the MDL, no qualifications were applied to the data. Paxton Data Validation 26 November 2024 Page 4 DVR L1758896 R3.docx Final Review: K Henderson 11/26/2024 1.5 Laboratory Control Sample (LCS) LCSs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One LCS/LCS duplicate (LCSD) pair was reported for batch WG2331265. The recovery and RPD results were within the laboratory specified acceptance criteria. 1.6 Field Duplicate One field duplicate was collected with the sample set, MW-25. Acceptable precision (RPD<30%) was not demonstrated between the field duplicate and the original sample MW-1. Oil and grease were not detected in the original sample MW-1 at or above the MDL. Oil and grease were detected at an estimated concentration greater than or equal to the MDL and less than the reporting detection limit (RDL) in the field duplicate sample MW-25, resulting in a non-calculable RPD between MW-1 and MW-25. Therefore, based on technical and professional judgement the oil and grease data were J or UJ qualified as estimated or estimated non-detect.

The results are considered valid; the analytical completeness defined as the ratio of the number of valid analytical results (valid analytical results include values qualified as estimated) to the total number of analytical results requested on samples submitted for analysis, for the sample set is 100%. 2.1.2 Analysis Anomaly The pH’s of samples MW-2, MW-10, and MW-9 did not meet the method criteria of pHs ≤ 2. Therefore, the samples were considered unpreserved. 2.2 Holding Time The holding time for TPH low fraction analysis of a preserved water sample is 14 days from sample collection to analysis. The holding time for TPH low fraction analysis of an unpreserved water sample is 7 days from sample collection to analysis. The holding times were met for the sample analyses, with the following exception. Sample MW-2 was analyzed outside the holding time of an unpreserved sample. Therefore, the TPH low fraction concentration for sample MW-2 was J qualified as estimated.

One method blank was reported for TPH low fraction by US EPA method 8015D/GRO (batch WG2329885). TPH low fraction (0.0744 mg/L) was detected in the method blank at an estimated concentration greater than or equal to the MDL and less than the RDL. Therefore, based on technical and professional judgement, the TPH low fraction data with estimated recoveries greater than or equal to the MDL and less than the RDL were U qualified as non-detect and reported at the RDL. In addition, the TPH low fraction concentrations greater the RDL and less than five times the method blank concentration were J+ qualified as estimated with high bias. The TPH low fraction data with concentrations greater than five times the method blank concentration were not qualified. Since the TPH low fraction concentration for sample MW-2 was also qualified for holding time exceedance and MS/MSD RPD outside criteria, the final qualification was J qualified as estimated.

Three method blanks were reported (batches WG2330260, WG2330346 and WG2332276). VOCs were not detected in the method blanks at or above the MDL. 3.4 Matrix Spike/Matrix Spike Duplicate One sample specific MS/MSD pair was reported using sample MW-2. The recovery and RPD results were within the laboratory specified acceptance criteria, with the following exceptions. Cis-1,2-dichloroethene was flagged ‘V’ by the laboratory indicating the concentration of cis-1,2- dichloroethene in the original sample, MW-2, was greater than the spike concentration. Therefore, based on technical and professional judgement, no qualifications were applied to the data. The recoveries of acrolein, carbon tetrachloride, chloroethane, 1,2-dichloroethane, 1,1,2- trichlorotrifluoroethane, and trichlorofluoromethane in the MS/MSD of sample MW-2 were high and outside of the laboratory specified acceptance criteria. Since these analytes were not detected in sample MW-2 at concentrations greater than or equal to the MDLs, no qualifications were applied to the data. The recovery of methylene chloride in the MSD of sample MW-2 was high and outside of the laboratory specified acceptance criteria. Since methylene chloride was not detected in sample MW-2 at concentrations greater than or equal to the MDL, no qualifications were applied to the data. Sample specific MS/MSDs were not reported for batches WG2330346 and WG2332276. Accuracy and precision were assessed using an LCS/LCSD pair for batch WG2330346. Precision was assessed using an LCS for batch WG2332276. 3.5 Laboratory Control Sample LCSs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). One LCS/LCSD pair and two LCSs were reported. The recovery and RPD results were within the laboratory specified acceptance criteria, with the following exceptions. The recovery of acrolein in the LCS of batch WG2330260 was high and outside of the laboratory specified acceptance criteria. Since acrolein was not detected in the associated samples at concentrations greater than or equal to the MDL, no qualifications were applied to the data.

Pace Analytical National Mount Juliet, Tennessee analyzed the samples for the following analytical test: • Volatile Organic Compounds (VOCs) by United States (US) Environmental Protection Agency (EPA) Method TO-15. EXECUTIVE SUMMARY Overall, based on this Stage 2A data validation covering the quality control (QC) parameters listed below and based on the information provided, the data as qualified are usable for supporting project objectives. The qualified data should be used within the limitations of the qualifications. If there are results with two or more different qualifications due to multiple QC failures, the final qualification is reconciled in the electronic data deliverable (EDD) with qualifications. The data were reviewed based on professional and technical judgment and the following documents: • Quality Assurance Project Plan, Paxton Development, 203 to 225 West Paxton Avenue, Salt Lake City, Utah, Voluntary Cleanup Site #C-129, June 19, 2024 (herein referred to as the QAPP); • US EPA Contract Laboratory Program National Functional Guidelines for Organic Superfund Methods Data Review, November 2020 (EPA 540-R-20-005); Paxton Data Validation 22 November 2024 Page 2 DVR L1784259 R1.docx Final Review: K Henderson 11/26/2024 • The pertinent methods referenced by the data package. The following samples were analyzed in the data set: Laboratory ID Client ID L1784259-01 SV-1 L1784259-02 SV-2 Laboratory ID Client ID L1784259-03 SV-20 The samples were received within 0-6°C. No preservation issues were noted by the laboratory. The laboratory reported results for the analytical method(s) requested for each sample on the COC. The data validation report was revised on November 26, 2024, to make edits. 1.0 Volatile Organic Compounds The samples were analyzed for VOCs by US EPA method TO-15. The areas of data review are listed below. A leading check mark () indicates an area of review in which the data were acceptable. A preceding crossed circle (⊗) signifies areas where issues were raised during the validation review and should be considered to determine any impact on data quality and usability. Overall Assessment Holding Times Method Blank Laboratory Control Sample Surrogates ⊗ Field Duplicate Sensitivity Electronic Data Deliverable Review 1.1 Overall Assessment The VOC data reported in this data set are considered usable for supporting project objectives. The analytical completeness, defined as the ratio of the number of valid analytical results (valid analytical results include values qualified as estimated) to the total number of analytical results requested on samples submitted for this analysis, for the data set is 100%. 1.2 Holding Times The holding time for the VOCs analysis of a soil vapor sample is 30 days from sample collection to analysis. The holding times were met for the sample analyses. Paxton Data Validation 22 November 2024 Page 3 DVR L1784259 R1.docx Final Review: K Henderson 11/26/2024 1.3 Method Blank Method blanks were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). Two method blanks were reported (batches WG2374030 and WG2376939). VOCs were not detected in the method blanks at or above the method detection limits (MDLs), with the following exceptions. Propene and TPH were detected in the method blank of batch WG2374030 at estimated concentrations greater than or equal to the MDLs and less than the reported detection limits (RDLs). However, since propene was not detected in the associated samples at concentrations greater than or equal to the MDL, no qualifications were applied to the propene data. Since the associated samples had detected concentrations of TPH greater than ten times the concentration of TPH in the method blank, no qualifications were applied to the TPH data. 1.4 Laboratory Control Sample (LCS) LCSs were analyzed at the proper frequency for the number and types of samples analyzed (one per batch of 20 samples). Two LCS/LCS duplicate (LCSD) pairs were reported for batches WG2374030 and WG2376939. The recovery and relative percent difference (RPD) results were within the laboratory specified acceptance criteria. 1.5 Surrogates The surrogate recoveries were within the laboratory specified acceptance criteria. 1.6 Field Duplicate One field duplicate was collected with the sample set, SV-20. Acceptable precision (RPD<30%) was demonstrated between the field duplicate and the original sample SV-2, with the following exceptions. The RPDs of acetone, 1,1-dichloroethane, cis-1,2-dichloroethene, trans-1,2-dichloroethene, ethanol, methylene chloride, tetrachloroethene, trichloroethene, and 1,2,4-trimethylbenzene between the field duplicate sample SV-20 and original sample SV-2 were high and outside of the laboratory specified acceptance criteria. Therefore, the data of these analytes were J qualified as estimated in the field duplicate sample SV-20 and original sample SV-2. Carbon disulfide was not detected at or above the RDL in the field duplicate sample SV-20 but was detected at a concentration greater than the RDL in the original sample SV-2, resulting in a non-calculable RPD. Therefore, the carbon disulfide data of the field duplicate sample SV-20 and original sample SV-2 were UJ or J qualified as estimated non-detect or estimated. Paxton Data Validation 22 November 2024 Page 4 DVR L1784259 R1.docx Final Review: K Henderson 11/26/2024 N-Hexane was not detected at or above the RDL in the field duplicate sample SV-20 but was detected at a concentration greater than the RDL in the original sample SV-2, resulting in a non- calculable RPD. Therefore, the n-hexane data of the field duplicate sample SV-20 and original sample SV-2 were UJ or J qualified as estimated non-detect or estimated.

J The analyte was positively identified; the associated numerical value is the approximate concentration of the analyte in the sample. J+ The analyte was positively identified; however, the associated numerical value is likely to be higher than the concentration of the analyte in the sample due to positive bias of associated QC or calibration data or attributable to matrix interference. J- The analyte was positively identified; however, the associated numerical value is likely to be lower than the concentration of the analyte in the sample due to negative bias of associated QC or calibration data or attributable to matrix interference. UJ The analyte was not detected above the reported sample quantitation limit. However, the reported quantitation limit is approximate and may or may not represent the actual limit of quantitation necessary to accurately and precisely measure the analyte in the sample. R The sample results are rejected due to serious deficiencies in the ability to analyze the sample and meet quality control criteria. The presence or absence of the analyte cannot be verified.
