Berger Lane, Murray, Utah. Please refer to Figure 1 for the Site Vicinity Map. This report was produced for Shupe Builders and the Utah Department of Environmental Quality (UDEQ) Division of Waste Management and Radiation Control (DWMRC). 1.1 Site Description The property consists of developed and undeveloped land located near the southeast corner of the intersection of 300 West and Berger Lane, Murray, Utah. In total, the property comprises eight parcels of land approximately 7.34 acres in size. The property is developed with several building structures occupied primarily by Tuck Landscape, camper and trailer storage, and two residential structures. The surrounding area consists mainly of commercial properties with some residential properties present as well. 1.2 Purpose and Scope The purpose of the Expanded Subsurface Investigation was to further delineate soil and potential groundwater impacts beneath the property as the site is proposed to be redeveloped primarily for residential use. In conversations with representatives with the DWMRC, further characterization of the site was necessary to determine if historical activities/uses have impacted soil and groundwater beneath the property. Based on previous sampling investigations and the site history, the contaminants of concern (COC) for the soil and groundwater are heavy metals. Upon completion of the expanded investigation, potential remedial activities will be evaluated that may include soil excavation, groundwater monitoring, institutional controls, and environmental covenants, if necessary. 1.3 Previous Assessments and Sampling Results In June 2023 EBI Consulting (EBI, June 7, 2023) conducted a Phase I ESA for the Subject Property. According to the report, Recognized Environmental Conditions (RECs) were identified at the Subject Property. The RECs were associated with the former Murray Smelter, located at 5300 S. Main Street, Murray, Utah, which is located approximately 0.5-miles to the south- southeast of the Subject Property. Because of the close proximity of the former smelter to the Subject Property, EBI conducted a file review of the USEPA Superfund online database. Based upon review of the documentation, it was determined that the western boundary of Murray Smelter Operable Unit (OU-1) is located adjacent to the eastern boundary of the Subject Property. The former Murray Smelter consisted of 142 acres of land that was utilized as a mineral processing plant with numerous smoke stacks. The area of the former Murray Smelter has been redeveloped into the Intermountain Medical Center and additional commercial uses such as the Murray Central light rail station. A review of the Record of Decision (ROD) prepared by the USPEA, dated 1998 indicates that investigations were completed in two areas; “on- facility” area meaning the 142 acres of the former operational areas of the Murray Smelter and adjacent Germania Smelter as well as “off-facility” area noted to be approximately 30 acres west of the facility, 106 acres to the south and southwest of the on-facility area and a small areas between 5200 South Street and Little Cottonwood Creek to the east of the on-site facility area. The west portion of the off-facility area is bounded by Little Cottonwood Creek to the north, 300 West Street to the west, 5300 South Street to the south, and the on-facility boundary to the east. Based upon review of the information, it was determined that the Subject Property is included within the off-facility area of the Murray Smelter ROD. The off-facility boundaries Murray Station Apartments February 2024 Expanded Subsurface Investigation Report Version 1 Project No. 271EM00850 Page 2 Atlas Technical Consultants LLC were determined by the USEPA based on the results of air dispersion modeling performed in November 1994. For environmental sampling, the 136 acre off-facility area was divided into eight “initial study zones” (ISZ’s). The Subject Property is located within ISZ-1, within the figures of the ROD. A review of Figure 11 - Lead Concentrations Measured In Surface Soil In ISZ-1, indicates four samples were collected from the Subject Property and submitted for laboratory analysis. Groundwater samples were not collected during the investigation. The results of the laboratory analysis indicated lead concentrations of 700 mg/kg, 2,100 mg/kg, 1,900 mg/kg, and 2,200 mg/kg. As indicated in the USEPA ROD for the Murray Smelter, lead impacted soil has been identified at the Subject Property at elevated concentrations. In addition, groundwater impacts have been identified beneath the former Murray Smelter property. Based upon review of the information, EPI identified the metals contamination as a REC to the Subject Property, and recommended further investigation. In September 2023, EBI conducted a limited subsurface investigation at the Subject Property (EBI Consulting, September 8, 2023). As part of the investigation, 10 soil borings were advanced and five surface soil samples were collected from a soil pile located near the northeast corner of the Subject Property. The soil borings were advanced to a depth of 10 feet below grade. Groundwater was not encountered during the investigation. The results of the subsurface investigation revealed the presence of arsenic and lead in soil above the USEPA Risk Screening Levels and above the State of Utah Background Threshold Values (UDEQ DWMRC Technical Guidance for Risk Assessments: Utah Administrative Code R315-101, June 2023), throughout the Subject Property. 2.0 SITE CHARACTERIZATION TASKS This section describes the field activities and sampling rationale that was performed during the expanded subsurface investigation effort. Specifics about the field sample collection methods, equipment, sample custody, and the management of investigation-derived wastes where provided in the workplan (Atlas, December 13, 2023). Sampling was concentrated in areas not previously sampled during the previous subsurface investigation. 2.1 Soil Boring Advancement and Sample Collection Five soil borings were advanced to characterize subsurface conditions beneath the property with all of the soil borings converted to monitoring wells. The monitoring well installation procedures are discussed in Section 2.2 of this report. The soil boring and monitoring well locations are present in Figure 2. The soil borings were advanced using direct push technology. Prior to the start of the field work, Atlas contacted the Utah Blue Stakes Center and scheduled a utility locate for the investigation area. In addition, a private underground utility locator was utilized to verify that there were no underground utilities present within two feet of the proposed boring locations and each soil boring was day-lighted to a depth of 5-feet below grade using a hydrovac system. During the day-lighting effort, hand auger samples were collected in each soil boring at 2 and 4-feet below grade. During direct push drilling a macro sampler equipped with a nylon sample liner was utilized to collect continuous soil samples starting at a depth of 5-feet and ending at a depth of approximately 17 feet. All soil samples were field logged by an experienced geologist. The logging information included soil type (Unified Soil Classification), color, consistency, moisture content, odor, and organic vapor monitor (OVM) readings. The OVM was calibrated with 100 Murray Station Apartments February 2024 Expanded Subsurface Investigation Report Version 1 Project No. 271EM00850 Page 3 Atlas Technical Consultants LLC ppm isobutylene at the start of each day of sampling. Immediately following retrieval, a composite of each soil sample interval (approximate 2-ft. intervals) was transferred to laboratory provided jars and to a zip lock type plastic bag. The soil samples were collected by a Utah Certified Soil and Groundwater Sampler in general accordance with the sampling protocol as set by Utah State and the Environmental Protection Agency. The field portable OVM was used to screen each bag after adequate time passed for volatilization and capture of organic vapors inside the bags. The field logging observations and OVM data described above were used to select appropriate samples for chemical analysis. The samples were labeled and immediately stored in an insulated cooler with ice to maintain an appropriate temperature of approximately 4ºC. Soil samples (at least three per boring) were submitted to a State of Utah certified laboratory for RCRA 8 metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) using EPA Method 6020/7471. In addition, the sample with the highest lead and arsenic concentrations was analyzed for the toxicity characteristic leaching procedure (TCLP). All soil samples were maintained under chain of custody documentation throughout the sample collection, storage, transportation, and laboratory analysis process. All of the samples were submitted to the laboratory requesting a normal turn-around time of 10 to 15 business days. The subsurface sampling equipment was decontaminated prior to arrival and between each borehole with brushes and a non-phosphate detergent (Alconox) and rinsed with tap water. An equipment blank quality assurance sample was obtained during soil boring advancement. After the drill rods were cleaned with non-phosphate detergent (Alconox) and rinsed with tap water, distilled water was poured over the decontaminated piece of equipment and collected in containers that were appropriate for metals. Quality control Level 3 was used by the analytical laboratory. 2.2 Monitoring Well Installation and Sample Collection In addition to the soil boring advancement effort discussed above, all of the soil borings were converted to 2-inch diameter groundwater monitoring wells. The wells were installed to a depth of approximately 17 feet below the ground surface (bgs) with the use of direct push drill rig. The wells were constructed with 10 feet of 2-inch diameter, 0.010-inch slotted, non-plugging schedule 40 PVC well screen. Each well was packed with pre-washed silica sand that extended 2-feet above the well screen and then sealed with hydrated bentonite chips to within 1 foot of the ground surface. Each well was completed with a 7-inch diameter flush-mounted monument embedded in concrete with a locking well cap. In addition, a top of well casing survey was also conducted by a professional survey contractor. The monitoring well construction details are summarized in Table 1 and presented on the soil boring logs in Appendix A. Development of the wells was performed as soon as it was practical after the wells were installed, but no sooner than 48 hours after the installation. The wells were developed with the use of disposable bailers. The wells were purged of at least five well volumes of water or until dry during the development. Following the well development, the wells were allowed to recover at least 48 hours to the static water level prior to purging and sampling. The depth to water was measured prior to purging and sample collection to ensure data consistency, to calculate well volumes, and to record fluctuations. The depth to groundwater was measured with an electronic water level indicator probe to the nearest 0.01-foot from a marked point on the top of the well casing. The water level probe was decontaminated between each well with the use of non-phosphate detergent (Alconox) and rinsed with tap water. The Murray Station Apartments February 2024 Expanded Subsurface Investigation Report Version 1 Project No. 271EM00850 Page 4 Atlas Technical Consultants LLC time and date of the measurement, point of reference, measurement method, depth-to-water measurement, and calculations were recorded on sampling data sheets. The groundwater elevations were used to calculate and plot the approximate hydraulic gradient and groundwater flow direction across the property. From the information obtained for the casing diameter, total well depth and depth-to-water measurements, the volume of water in the well was calculated. This well volume was used to determine the minimum volume of water to be purged from the well before the sample was collected. The color, clarity, and odor of the water was recorded as the water was purged. Odors, sheens or other evidence of contamination in the water samples was noted. New dedicated polyethylene tubing was used for each well. After approximately one liter was removed during the purging, a flow-through cell was connected to the discharge tubing of the pump. The flow-through cell allowed for measurements of water-quality-indicator parameters without allowing contact with the atmosphere. Measurements for temperature, pH, oxidation reduction potential (ORP), specific conductance (SEC), dissolved oxygen (DO), and turbidity were recorded as each one-half well volume was removed with a water multi-parameter meter. Purging ceased when measurements for all five parameters had stabilized for three consecutive readings. If the wells were purged relatively dry, the wells were allowed to recharge to near the static water level before being sampled after purging one additional liter of water. After the purging had been completed, the groundwater samples were collected by a Utah Certified Soil and Groundwater Sampler in general accordance with the sampling protocol as set by Utah State and the Environmental Protection Agency. The same device and tubing used during the purging was used for sample collection to help minimize disturbance of the water column, and reduce volatilization and turbidity. The bottom of the HDPE tubing was set approximately in the middle of the water column within each well. During the low flow sampling, the peristaltic pump was restricted to less than 200 milliliters per minute to help minimize draw down of the groundwater. The water samples were transferred directly to laboratory provided containers. The samples were labeled and immediately stored in an insulated cooler with ice to maintain an appropriate temperature of approximately 4ºC. The groundwater samples were submitted to a State of Utah certified laboratory for RCRA 8 metals (arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver) analysis using EPA Method 6020/7470. During the sampling of the wells, one blind field duplicate groundwater sample was obtained. Quality control Level 3 was used by the analytical laboratory. 2.3 Equipment Decontamination Procedures Disposable sampling equipment (nitrile gloves and polyethylene tubing) were used where possible to reduce the amount of equipment that needed to be decontaminated between sample locations. The Geoprobe rods in contact with the on-site soils were decontaminated between locations by washing the equipment with a power washer, brushes and non-phosphate detergent (Alconox) and rinsing the equipment with tap water. Gloves, PVC liners and other investigation derived waste were disposed off-site at a municipal sanitary landfill. Soil cuttings generated during soil sampling; and monitoring well development and purge water removed during groundwater sampling, were contained in 55-gallon drums. The investigative derived is currently stage on-site pending disposal at a permitted facility. Murray Station Apartments February 2024 Expanded Subsurface Investigation Report Version 1 Project No. 271EM00850 Page 5 Atlas Technical Consultants LLC 3.0 SITE CHARACTERIZATION RESULT AND FINDINGS 3.1 Subsurface Lithology Subsurface lithology encountered during the investigation consisted primarily of fill material (sand, silt, and gravel) to a depth of approximately 2 to 3-feet bgs. Beneath the fill material, medium grained sand was primarily encountered to the depth of approximately 10 to 11-feet bgs. Beneath the medium grained sand, silty sand and very fine sand were primarily encountered to the depth of soil borings at 17 feet bgs. Groundwater was encountered during drilling at a depth of approximately 11 to 12-feet bgs. No organic vapors above the background value of 1.0 ppm-v were measured during sampling. The OVM measurements collected in the field are included with soil boring logs in Appendix A. 3.2 Groundwater Gradient Analysis Groundwater elevation data collected from wells was used to generate a groundwater flow direction map for the site. The data indicate that groundwater flows is to the northwest at a gradient of 0.004 ft/ft between MW -4 and MW -1. The groundwater elevation data are summarized in Table 1 and the groundwater gradient map is presented as Figure 3. 3.3 Soil Analysis Summary Review of the metals analytical data indicate the presence of arsenic above the USEPA Residential Risk Screening Level (RSL – 0.68 mg/kg) and above the UDEQ DWMRC Background Threshold Value (BTV – 27 mg/kg) in the soil samples collected from SB-14/MW -4 @ 2-3’ (98.0 mg/kg) and SB-15/MW -5 @ 8-10’ (32.6 mg/kg). Lead was also measured above its Residential RSL (400 mg/kg) and BTV (60 mg/kg) in the soil sample collected from SB- 14/MW -4 @ 2-3’ (560 mg/kg). Cadmium and mercury were also measured above their BTVs in several samples; however, the concentrations measured did not exceeded their respective USEPA Residential RSLs. Lead was also measured above its BTV in the soil sample collected from SB-11/MW -1 @ 2-3’ (202 mg/kg); however, the concentration is below the USEPA Residential RSL of 400 mg/kg. No other USEPA Residential RSLs or UDEQ DWMRC BTVs were exceeded in any of the other soil samples submitted for laboratory analysis. The soil metals data are summarized in Table 2 and copy of the analytical reports are included in Appendix B. In addition to the soil analysis discussed above, the soil sample (SB-14/MW -4 @ 2-4’) measuring the highest arsenic and lead concentrations was analyzed for the Toxicity Characteristic Leaching Procedure (TCLP). The results indicated an arsenic concentration of 0.881 mg/L and a lead concentration of 0.728 mg/L. Based upon review of the data, it is unlikely that the soil beneath the site would be classify as hazardous waste. The TCLP metals data are summarized in Table 3 and copy of the analytical report is included in Appendix B. 3.4 Groundwater Analysis Summary Review of the groundwater metals data indicate the presence of arsenic above the USEPA MCL of 10.0 µg/L in MW -1 (13.8 µg/L). Lead was also measured above its MCL of 15 µg/L in MW -3 (20.9 µg/L), MW -4 (21.6 µg/L), and in the blind duplicate sample (BDS-1) collected from MW -4 (22.2 µg/L). Selenium was also measured above its MCL of 50 µg/L in MW -4 (83.2 µg/L), and in BDS-1 collected from MW -4 (84.0 µg/L). The UDEQ has not established ISLs for metals. No other metals were measured above their respective MCLs in any of the other groundwater samples submitted for analysis. The groundwater metals data are summarized in Table 4 and copies of the analytical reports are included in Appendix B. Murray Station Apartments February 2024 Expanded Subsurface Investigation Report Version 1 Project No. 271EM00850 Page 6 Atlas Technical Consultants LLC 3.5 Data Validation and Assessment The objectives of the data validation and assessment program for this investigation was to examine and validate all data and documentation from field and laboratory instrumentation and method quality assurance elements to ensure that all requirements specified in the Workplan (Atlas, December 2023) had been met. The samples were analyzed for the contaminants of concern in accordance with the approved test methods using USEPA Quality Assurance Level 3 reporting. The data validation reports included analysis of the sample holding times, laboratory method blanks, laboratory control sample analysis, matrix spike analysis, matrix spike duplicate analysis, field duplicate analysis, completeness of data and an overall assessment of the sensitivity, accuracy, precision, completeness, representativeness and comparability of the data. The method blanks, matrix spikes, matrix spike duplicates and laboratory control samples were analyzed for each group of samples analyzed together by the laboratories using samples selected from this investigation. All samples were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times. Where applicable, all method detection limits (MDLs) and Reported Detection Limits (RDLs) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in the laboratory report case narrative. The following laboratory qualifiers were identified by the testing laboratory during the data validation and assessment process for analytes concentrations that were measured at or above the laboratory method detection limits: B - The same analyte is found in the associated blank J - Identification of analyte is acceptable; the reported value is an estimate. J3 - The associated batch QC was outside the established quality control range for precision. 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 an accurate determination; spike value is low. O1 - The analyte failed the method required serial dilution test and/or subsequent post- spike criteria. These failures indicate matrix interference. 4.0 CONCLUSIONS AND RECOMMENDATIONS Review of the metals analytical data indicate the presence of arsenic above the USEPA Residential RSL and above the UDEQ DWMRC BTV in two soil samples ((SB-14/MW -4 @ 2-3’ (98.0 mg/kg) and SB-15/MW -5 @ 8-10’ (32.6 mg/kg)). Lead was also measured above its Residential RSL and BTV in one soil sample ((SB-14/MW -4 @ 2-3’ (560 mg/kg)). Cadmium and mercury were also measured above their BTVs in several samples; however, the concentrations did not exceeded their respective USEPA Residential RSLs. No other USEPA Residential RSLs or UDEQ DWMRC BTVs were exceeded in any of the other soil samples submitted for laboratory analysis. Review of the groundwater metals data indicate the presence of arsenic above the USEPA MCL of 10.0 µg/L in MW -1. Lead was also measured above its MCL of 15 µg/L in MW -3 and MW -4. Selenium was also measured above its MCL of 50 µg/L in MW -4. No other metals were Murray Station Apartments February 2024 Expanded Subsurface Investigation Report Version 1 Project No. 271EM00850 Page 7 Atlas Technical Consultants LLC measured above their respective MCLs in any of the other groundwater samples submitted for analysis. Based upon review of the historical data (EBI, September 2023) and data collected during this investigation, it appears that arsenic and lead impacted soil are present above the DWMRC BTVs and above the USEPA Residential RSLs starting at the surface down to a depth of approximately 5-feet below grade. Below approximately 5-feet, metals are present; however, the concentrations measured are either below their respective BTVs or below their respective USEPA RSLs. Review of the groundwater data indicate arsenic, lead, and selenium are also present above their respective MCLs. Information provided by the property owner indicates that during redevelopment the soil currently present will remain on-site and that the site will be graded to the appropriate elevation prior to construction. Upon completion of the site grading effort, imported clean fill will then be utilized to build the site up to the appropriate elevation prior to construction of the apartment complex. Based upon review of the data collected at the site, Atlas recommends that a Corrective Action Plan (CAP) be prepared to manage the metals impacted soil during redevelopment of the property. 5.0 REFERENCES EBI Consulting, Phase I Environmental Site Assessment, Berger Lane Property, 261, 257, 237, 179, 171, 173, 175, 177 Berger Lane, Murray, Utah, June 7, 2023.

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. Incpt Intercept. Mass Mass of parameter. MDL Method Detection Limit. RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. RSD Relative Standard Deviation. 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 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. 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. O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate matrix interference. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: One Atlas 271EM00850 L1702045 02/12/24 10:18 186 of 189 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: One Atlas 271EM00850 L1702045 02/12/24 10:21 186 of 189 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: One Atlas 271EM00850 L1702045 02/12/24 10:18 187 of 189 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: One Atlas 271EM00850 L1702045 02/12/24 10:21 187 of 189 ANALYTICAL REPORT February 15, 2024 Revised Report One Atlas Sample Delivery Group:L1704712 Samples Received:02/03/2024 Project Number:271EM00850 Description:Murray Station Apts.

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. Incpt Intercept. Mass Mass of parameter. MDL Method Detection Limit. RDL 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.

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. Incpt Intercept. Mass Mass of parameter. MDL Method Detection Limit. RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. RSD Relative Standard Deviation. 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 J The identification of the analyte is acceptable; the reported value is an estimate. 1 Cp 2 Tc 3 Ss 4 Cn 5 Su 6 Gl 7 Al 8 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: One Atlas 271EM00850 L1704195 02/16/24 07:48 75 of 77 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: One Atlas 271EM00850 L1704195 02/16/24 08:15 75 of 77 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: One Atlas 271EM00850 L1704195 02/16/24 07:48 76 of 77 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: One Atlas 271EM00850 L1704195 02/16/24 08:15 76 of 77
