Morehead Street, Suite 400 Charlotte, North Carolina 28202 Subject: Soil Sampling Letter Report Elan University City Site Charlotte, North Carolina Mid-Atlantic Project No. 000H1531.00 Dear Glover: Mid-Atlantic Associates, Inc. (Mid-Atlantic) is pleased to submit this Soil Sampling Letter Report for conducting assessment activities at the Elan University City Site located on University City Boulevard near Interstate 85 in Charlotte, North Carolina (Subject Property). The property is depicted in the Site Location map included as Drawing 1. The objective of our scope of services was to determine if metals were present in soils at the Subject Property at concentrations in excess of established Preliminary Soil Remediation Goals (PSRGs). 1.0 Background The Subject Property encompasses approximately 71.94 acres and is assigned the Mecklenburg County Parcel ID Numbers 04708213, 04708214, and 04739110. The Site is not currently developed. In July 2021, Elan University City Phase 2, LLC submitted a Brownfield Property Application to the North Carolina Department of Environmental Quality, Brownfields Program (NCBP). During a February 23, 2022 virtual meeting with the NCBP, the NCBP concurred that the presence of metals in soil at the Subject Property above PSRGs would satisfy concerns about a sufficient hindrance at the site and allow a Letter of Eligibility to be issued. 1125 E. Morehead Street, Suite 104 Charlotte, NC 28204-2849 Office: 980. 585.1271 Facsimile: 980. 585.1272 Soil Sampling Letter Report May 16, 2022 Elan University City Site, Charlotte, NC Page 2 Mid-Atlantic Project No. 000H1531.00 2.0 Preliminary Soil Sampling Activities The assessment activities were conducted in general accordance with the North Carolina Department of Environmental Quality (NCDEQ) Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup dated July 2021 and most recent versions of the United States Environmental Protection Agency (USEPA) Region IV Science and Ecosystem Support Division (SESD) Field Branches Quality System and Technical Procedures guidelines. Based on our discussions and review of the recently completed Phase I ESA for the Site, Mid-Atlantic proposed to advance three (3) soil borings (SB-1 through SB-3) for the collection of soil samples. The soil boring locations are depicted on Drawing 3 and located as follows: • Soil boring SB-1 was the northern most of the three soil borings along the southwestern portion of the Subject Property and was sampled at a depth between 2.0-2.5 ft below ground surface (BGS). • Soil boring SB-2 was the middle of the three soil borings along the southwestern portion of the Subject Property and was a composite of the 2.0-2.5 ft, 4.0-4.5 ft, 6.0-6.5 ft, and 8.0-8.5 ft BGS intervals. • Soil boring SB-3 was the southern most of the three soil borings along the southwestern portion of the Subject Property and was sampled at a depth between 2.0-2.5 ft BGS. The soil sampling methodology, laboratory analytical results, and recommendations are provided in the sections below. 2.1 Soil Sampling Methodology On April 8, 2022, Mid-Atlantic mobilized to the Subject Property to advance three (3) soil borings (SB-1 through SB-3) across southern portion of the Subject Property. Mid-Atlantic utilized a decontaminated stainless-steel hand auger to advance the soil borings to a depth of 2.5 ft BGS for SB-1 and SB-3; and a depth of 8.5 ft BGS for SB-2. Continuous soil samples were collected from the center of the hand auger bucket at each soil boring location. Field screening did not indicate obvious signs of impacts, therefore Mid-Atlantic collected soil samples from the 2.0 to 2.5 ft BGS depth interval in all three soil borings and 4.0 to 4.5 ft, 6.0 to 6.5 ft and, 8.0 to 8.5 ft at the SB-2 location. Soil Sampling Letter Report May 16, 2022 Elan University City Site, Charlotte, NC Page 3 Mid-Atlantic Project No. 000H1531.00 The sample containers were labeled with the sample identification, date, time, and requested analysis, and placed in a laboratory supplied cooler with ice. The samples were delivered to Waypoint Analytical (Waypoint) in Charlotte, North Carolina under standard chain-of-custody protocol. Soil samples collected were submitted for laboratory analysis of 13 Priority Pollutant metals and Hexavalent Chromium. by EPA Method 6020B. Following soil sample collection, the soil borings were properly abandoned, and the surface was repaired similar to pre-hand auguring conditions. 2.2 Soil Analytical Results A tabular summary of the soil analytical results is provided in Table 1 and a sample location map is presented as Drawing 3. The laboratory analytical report and chain-of- custody form is provided in Appendix A. The analytical results were compared to the NCDEQ Residential Preliminary Soil Remediation Goals (PSRGs) dated January 2022. Soil laboratory results indicated the following: • Arsenic concentrations in SB-1, SB-2 and, SB-3 exceed their respective Residential PSRGs; • Iron concentrations in SB-1, SB-2 and, SB-3 exceed their respective Residential PSRGs; • Thallium concentrations in SB-3 exceed the Residential PSRG; • No other Metals were detected above method detection limits. 3.0 Summary and Conclusions Mid-Atlantic has completed limited soil assessment activities at the Elan University City Site located on University City Boulevard near Interstate 85 in Charlotte, North Carolina. The assessment activities were conducted following the approval of our Proposal for Preliminary Soil Sampling dated March 29, 2022. Assessment activities are summarized as follows: • Mid-Atlantic oversaw the advancement of three soil borings (SB-1 through SB-3) for the collection of soil samples on the Subject Property; • Arsenic and Iron concentrations in SB-1, SB-2 and, SB-3 exceeded their respective Residential PSRGs; • Thallium concentrations in SB-3 exceed the Residential PSRG; • No other metals were detected above method detection limits.

The sample quantitation limit has been corrected for dilution and for percent moisture, unless otherwise noted in the case narrative. J Estimated value due to either being a Tentatively Identified Compound (TIC) or that the concentration is between the MRL and the MDL. Concentrations are not verified within the linear range of the calibration. For DoD: concentration >40% difference between two GC columns (pesticides/Arclors). B Analyte was also detected in the associated method blank at a concentration that may have contributed to the sample result. E Inorganics- Concentration is estimated due to the serial dilution was outside control limits. E Organics- Concentration has exceeded the calibration range for that specific analysis. D Concentration is a result of a dilution, typically a secondary analysis of the sample due to exceeding the calibration range or that a surrogate has been diluted out of the sample and cannot be assessed. * Indicates that a quality control parameter has exceeded laboratory limits. Under the “Notes” column of the Form I, this qualifier denotes analysis was performed out of Holding Time. H Analysis was performed out of hold time for tests that have an “immediate” hold time criteria. # Spike was diluted out. + Correlation coefficient for MSA is <0.995. N Inorganics- Matrix spike recovery was outside laboratory limits. N Organics- Presumptive evidence of a compound (reported as a TIC) based on the MS library search. S Concentration has been determined using Method of Standard Additions (MSA). W Post-Digestion Spike recovery is outside control limits and the sample absorbance is <50% of the spike absorbance. P Concentration >40% difference between the two GC columns. C Confirmed by GC/MS Q DoD reports: indicates a pesticide/Aroclor is not confirmed (100% Difference between two GC columns). X See Case Narrative for discussion. MRL Method Reporting Limit. Also known as: LOQ Limit of Quantitation (LOQ) The lowest concentration at which the method analyte may be reliably quantified under the method conditions. MDL Method Detection Limit. A statistical value derived from a study designed to provide the lowest concentration that will be detected 99% of the time. Values between the MDL and MRL are estimated (see J qualifier). LOD Limit of Detection. A value at or above the MDL which has been verified to be detectable. ND Non-Detect. Analyte was not detected at the concentration listed. Same as U qualifier.
