Property Description 1.1 Location and Legal Description WR has performed a Limited Phase II ESA on a ±3.05-acre site located in the northwestern quadrant of the intersection of Youth Center Drive and Hillsborough Street in Raleigh, Wake County, North Carolina (Figure 1). According to Wake County GIS records, the subject property consists of the following eight parcels: 1 0784439213 2 0784438203 3 0784437117 4 0784436145 5 0784436239 6 1 0784435399 GATE 3 ENTERPRISES LLC GATE 3 ENTERPRISES LLC GBH PARTNERS LLC GBH PARTNERS LLC Justin Booth CSB ENTERPRISES LLC 5200 Hillsborough Street ±0.46 5204 Hillsborough Street ±0.58 5210 Hillsborough Street 1 ±0.35 5212 Hillsborough Street ±0.33 108 Grand Avenue ±0.35 114 Grand Avenue; 5209 ±0.35 Dorcas Street 7 1 0784437326 I GATE 3 ENTERPRISES LLC 5205 Dorcas Street 1 ±0.23 8 0784437389 GATE 3 ENTERPRISES LLC 5203 Dorcas Street ±0.40 The current site layout is provided as Figure 2. This Limited Phase II ESA was completed at the request of FRH Realty LLC (Client) based on the findings of a Phase I ESA completed by WR on the subject site in May 2022. The use of the subject property has been for industrial, commercial and residential purposes since at least 1938 with uses including septic tank manufacturing, a beauty shop, radiator and lawn mower service, an electrical contractor, retail, sanitation service, mulch and stone sales, and car/boat storage. The commercial structure on Tract 4 was constructed in 1952, the residential structure on Tract 5 was constructed in 1920, and the residential structures on Tract 6 were constructed in 1925 and 1940. The subject property appears on the North Carolina Department of Environmental Quality (NCDEQ) underground storage tank (UST) database due to one 1,000-gallon gasoline UST identified on the subject property. According to information in an Environmental Database Resources (EDR) report ordered for the May 2022 Phase I ESA, the onsite UST was installed on May 5, 1966 and removed on September 1, 1988. Based on available information, there is no indication of a proper UST closure following NCDEQ guidelines. The exact location of the former onsite UST was not able to be determined during the May 2022 Phase I ESA, as no historical information or interviewed parties indicated the location of the former UST. A former 2019 Phase I ESA conducted on a portion of the subject site, and reviewed by WR, indicated that the UST was formerly located in the southeastern portion of Tract 1, which corresponds to the area of a former residential structure. However, this information was unable to be confirmed during WR's 2022 Phase I ESA. The former onsite UST was considered to represent a Recognized Environmental Condition (REC) during the May 2022 Phase I ESA. Additionally, WR observed a concrete foundation along the shared boundaries of Tracts 1, 2, and 8 (Figure 2). According to the current property owner representative, the foundation corresponds to a small concrete septic tank manufacturing facility that was built sometime in the 1950s and remained onsite until sometime in the 1970s or 1980s. The owner indicated that the septic tanks were poured by hand and/or by overhead Hillsborough Street Assemblage: Raleigh, NC WR No. 23-0302 Limited Phase II Environmental Site Assessment September 2023 1 ::WithersRavenel Our People. Your Success. cranes and that no other process equipment or petroleum/chemicals were used in the process, to knowledge. WR was unable to speak with a representative familiar with the site during the use of the site for septic tank manufacturing to determine if any chemicals/petroleum products common for industrial processes were used onsite. WR considered the former onsite manufacturing facility to represent an REC during the May 2022 Phase I ESA. Furthermore, according to historical resources researched during the completion of the May 2022 Phase I ESA, businesses such as refueling stations, beverage companies, wood processing facilities, and garages/auto repair facilities have historically been located in the vicinity of the subject property beginning by the early- to mid-1900s. Many of these businesses have been located on adjacent properties, and the associated buildings and USTs have been located as close as 50 feet from the subject property. Some of these properties are associated with incidents from USTs or spilled chemicals, and others have not had incidents reported for the facility. Some of the nearby sites were listed in 2022 on NCDEQ's UST database with remaining onsite USTs. One of the nearby properties with a confirmed release corresponds to a southeastern adjacent property known as Jean's Starflite (Figure 2). Groundwater contamination reported in documents available in 2022 indicated contaminants having extended onto the southern portion of Tract 1 of the subject site. An additional nearby property is listed on the SHWS database and corresponds to a southern adjacent property known as the Burke's Hardware property (Figure 2). This listing corresponds to numerous vicinity water supply wells contaminated with chlorinated solvents, including trichloroethylene (TCE) and tetrachloroethylene (PCE). At the time of the May 2022 Phase I ESA, limited amounts of groundwater assessments had been conducted. A memo from NCDEQ in 2019 indicated that a groundwater plume is still present at the Burke's Hardware site. No determination of a source or groundwater flow direction had been reported at the time of the May 2022 Phase I ESA. WR considered the surrounding vicinity to represent an REC relative to the subject site. In light of the findings from the May 2022 Phase I ESA, FRH Realty LLC submitted a Brownfields Property Application to the NCDEQ Brownfields Redevelopment Section (BRS) and received a Letter of Eligibility from NCDEQ dated June 19, 2023. This assessment was completed in anticipation of FRH Realty LLC's participation in the BRS and includes the typical assessment protocols and requirements of the BRS. A BRS project manager had not yet been assigned to project when this assessment work was conducted and thus was not conducted pursuant to a BRS-approved work plan. The following report describes the limited assessment activities conducted at the subject property and the findings of this Limited Phase II ESA. 2 Field Assessment Activities 2.1 Utility Location and GPR/EM Survey Prior to conducting subsurface assessment activities at the subject site, WR contacted the North Carolina One Call Center (NC One Call) to locate underground utilities at the subject property. As NC One Call does not locate all utilities located within property boundaries, WR's Subsurface Utility Engineering (SUE) department mobilized to the subject site to locate private lines such as water, sewer, fiber optic, or other sub -surface utilities located in or near the areas of planned subsurface assessment. Congruent with assessment activities at the site on May 22, 2023, WR SUE utilized Ground Penetrating Radar (GPR) and Electromagnetic (EM) equipment to survey the fenced boat storge lot on Tracts 1, 2, 7, and 8 to determine if any USTs were present on these tracts. No USTs were discovered during the GPR/EM survey, which implies that the UST listed on NCDEQ's database had been removed from the subject site. Hillsborough Street Assemblage: Raleigh, NC WR No. 23-0302 Limited Phase II Environmental Site Assessment September 2023 2 ::WithersRavenel Our People. Your Success. 2.2 Soil Borings On May 11 and 12, 2023, WR, along with drilling subcontractor Quantex utilizing a track -mounted GeoProbe® drill rig, advanced 10 soil borings (TW-1 through TW-10) at various locations on the subject site into the subsurface water table, which generally corresponded to depths of approximately 20 or 25 feet below land surface (BLS). The locations of the soil borings were placed within the proposed footprint of the planned onsite residential structure, determined by a concept plan provided to WR by the Client. Soil borings TW-1 and TW-6 were completed on Tract 1, TW-2 was completed on Tract 2, TW-3 was completed on Tract 7, TW-4 and TW-5 were completed on Tract 8, TW-7 and TW-8 were completed on Tract 6, TW-9 was completed on Tract 5, and TW-10 was completed on Tract 4. See Figure 3 for a map indicating the soil boring locations. Soil was collected at approximate 2.5-foot intervals in each of the borings, classified, and placed in individual zip -lock baggies for field screening by a field calibrated MiniRAE3000 Photoionization Detector (PID) for the presence of total volatile organic vapors. No petroleum or chemical odors were noted during screening of the soil samples, with the exception of TW-6. PID readings in TW-6 were below 1 ppm for all intervals except the 20-22.5 feet BLS interval, which was 238 ppm. A petroleum odor was also noted in the 20-22.5 foot interval. The water table was observed at approximately 17 feet BLS in boring TW-6, indicating that the interval with the observed odor and elevated PID reading was within the water table below the site. The general lithology of the site consisted of clays and silts with some occurrences of sand and rock fragments/mica. Refer to the attached boring logs in Appendix A for soil classifications and PID readings. Soil samples were submitted for laboratory analysis from the 5-7.5 feet BLS interval in each completed soil boring, which was determined based on the possible future grading depths at the site and site observations/PID readings. The soil with the observed petroleum odor and elevated PID reading from TW- 6 was from a depth below the water table (-17.5 feet BLS) and was not submitted for laboratory analysis due to the soil being saturated with groundwater. A duplicate soil sample (DUP) was submitted from boring TW-6 from the same depth as the original TW-6 soil sample (5-7.5 feet BLS). Following collection, a small sample of soil was placed in a Ziplock baggie for vapor screening while the remaining sample was immediately placed in pre -preserved laboratory supplied glassware specific to the analysis requested for the samples. Each sample was immediately placed on ice within a cooler, and submitted under chain -of -custody protocols to Pace Analytical in Mount Juliet, TN. All soil samples submitted from the subject site were analyzed for volatile organic compounds (VOCs) by Environmental Protection Agency (EPA) Method 8260, semi-VOCs (SVOCs) by EPA Method 8270, RCRA-8 Metals by EPA Method 6020B, mercury by EPA method 7471B, and hexavalent chromium by EPA Method 7199. Copies of chain -of -custody records are included with the analytical results in Appendix B. Soil Analytical Results — VOCs, SVOCs, Metals Laboratory analytical results for the soil samples indicated the presence of targeted compounds at concentrations above the method detection limits (MDLs). Those results are summarized by analysis type below: • No targeted VOCs were reported at concentrations above MDLs for any of the soil samples submitted for analysis of VOCs, with the exception of a low concentration of tert-butyl benzene well below its current applicable NCDEQ preliminary soil remediation goals (PSRGs) in the soil sample submitted from TW-7. • Numerous targeted SVOCs were reported at concentrations above MDLs for soil samples submitted from TW-4 and TW-5. Two of the targeted SVOC concentrations were higher than current PSRGs, as follows: o The reported concentration of benzo(a)anthracene was 0.402 mg/kg in soil sample TW-4, which exceeds its protection of groundwater PSRG of 0.35 mg/kg. Hillsborough Street Assemblage: Raleigh, NC Limited Phase II Environmental Site Assessment WR No. 23-0302 September 2023 3 ::WithersRavenel Our People. Your Success. o The reported concentration of benzo(a)pyrene was 0.261 mg/kg in soil sample TW-4, which exceeds its residential health based PSRG of 0.11 mg/kg. o No targeted SVOCs were reported at concentrations exceeding applicable industrial/commercial health based PSRGs in any submitted soil sample. • Numerous targeted metals were reported at concentrations above MDLs for all soil samples submitted from the subject site. Several of the targeted metals concentrations were higher than current PSRGs, as follows: o The reported concentrations of arsenic exceeded the industrial/commercial health based PSRG for arsenic of 3.0 mg/kg in all soil samples submitted from the subject site, including elevated concentrations above 10 mg/kg in soil samples TW-3, TW-4, TW-7, TW-8, TW-9, and TW-10. o The reported concentrations of hexavalent chromium exceeded the residential health based PSRG for hexavalent chromium of 0.31 mg/kg, but below hexavalent chromium's industrial/commercial health based PSRG, in all soil samples submitted from the subject site, except for soil sample TW-10, which was not reported at a concentration exceeding its respective MDL. The laboratory analytical results for the soil samples are summarized in Table 1 and shown on Figure 3. Copies of the laboratory analytical reports are provided in Appendix B. 2.3 Groundwater Assessment On May 11 and 12, 2023, all 10 of the soil borings were converted into temporary groundwater monitoring wells. Locations of each temporary monitoring well are depicted on Figure 4 and Figure 5. The temporary monitoring wells were constructed with a one -inch diameter PVC screen section extending from the base of the boring connecting to one -inch diameter PVC risers to surface grade. Sand was placed around the screen section and bentonite was placed above the sand. The temporary monitoring wells were constructed as described in the boring logs in Appendix A and shown on Table 2A. Upon completion of temporary monitoring well construction, each temporary monitoring well was properly developed to remove as much suspended sediment from the groundwater as possible. Prior to purging and sampling each well, the depth to groundwater within the temporary monitoring wells was gauged utilizing an electronic water level indicator. However, the temporary monitoring wells were not equilibrated on May 11 or 12 due to slow recharge rates. Therefore, WR measured the water level in the 10 temporary groundwater monitoring wells on May 22, 2023 during additional assessment activities. The measured groundwater depths ranged from 16.52 feet to the top -of -casing (TOC) in TW-4 to 21.06 feet TOC in TW-7. WR used a laser level and level rod to survey the TOC elevations of all onsite temporary wells relative to each other based on an assumed elevation of 100 feet applied to TW-5. Based on the relative elevations and the measured water depths, WR calculated the relative groundwater elevation in each temporary well and determined the overall groundwater flow direction for the subject site. The groundwater flow direction for the subject site is to the northwest, following the topographic slope of the subject site. See Table 2A for all temporary monitoring well groundwater depths and calculated groundwater elevations; see Figure 4 for a groundwater contour map including groundwater elevations and flow direction. On May 11 and 12, 2023, each temporary monitoring well was purged of at least three well volumes, or until dry, utilizing dedicated polyethylene tubing and a peristaltic pump. The groundwater samples were then collected from the onsite temporary monitoring wells in pre -preserved laboratory supplied glassware specific to the analysis requested for the samples. A duplicate groundwater sample (DUP) was submitted from temporary well TW-6. Following collection, all groundwater samples were placed on ice within a cooler, and submitted under chain -of -custody protocols to Pace Analytical in Mount Juliet, TN for analysis of VOCs by Standard Method (SM) 6200, SVOCs by SM 625, and select metals including hexavalent chromium by Hillsborough Street Assemblage: Raleigh, NC WR No. 23-0302 Limited Phase II Environmental Site Assessment September 2023 4 ::WithersRavenel Our People. Your Success. the appropriate EPA methods. Copies of chain -of -custody records are included with the analytical results in Appendix B. Groundwater Analytical Results — VOCs, SVOCs, Metals Laboratory analysis results for the groundwater samples indicated the presence of targeted compounds at concentrations above MDLs. Those results are summarized by analysis type below: • Numerous targeted VOCs were reported at concentrations above MDLs for most groundwater samples submitted from the subject site. The following VOCs were reported at a concentration that exceeded their NC Groundwater Standard established in 15A NCAC 2L (NC 2L standard): o The reported concentration of benzene was 239 µg/L in groundwater sample TW-2, which exceeds its NC 2L standard of 1.0 µg/L. o The reported concentration of 1,2-dichloroethane (1,2-DCA) was 10.5 µg/L in groundwater sample TW-2, which exceeds its NC 2L standard of 0.4 µg/L. o The reported concentration of naphthalene was 19.2 µg/L in groundwater sample TW-2, which exceeds its NC 2L standard of 6.0 µg/L. o The reported concentration of m&p-xylenes was 676 µg/L in groundwater sample TW-2, which exceeds its NC 2L standard of 500 µg/L. • Numerous targeted SVOCs were reported at concentrations above MDLs for most groundwater samples submitted from the subject site. The following SVOC was reported at a concentration that exceeded its NC 2L standard: o The reported concentration of naphthalene was 11.3 µg/L in groundwater sample TW-1, which exceeds its NC 2L standard of 6.0 µg/L. • Numerous targeted metals were reported above MDLs for each groundwater sample submitted from the subject site; however, no reported metal concentrations exceeded relative NC 2L standards. o Additionally, neither Arsenic or Hexavalent Chromium was reported in the collected samples at a concentration exceeded 1 µg/L. • No reported concentrations of targeted compounds in submitted groundwater samples exceeded their respective gross contaminant levels (GCLs). The laboratory analysis results for the groundwater samples are summarized in Table 2B and shown on Figure 5. Copies of the laboratory analytical reports are provided in Appendix B. 2.4 Soil Vapor Assessment While onsite on May 11 and 12, 2023, 10 temporary soil vapor sampling probes (SVP) (VP-1 through VP- 10) were installed immediately adjacent to the 10 completed soil borings, as depicted on Figure 6. The SVPs were completed as described in the boring logs in Appendix A. The SVPs were allowed to sit for well over 24 hours to ensure a proper seal was achieved around each SVP. WR purged and sampled the ten SVPs on May 22, 2023. Prior to collecting soil vapor samples, each SVP was purged for 3 to 5 minutes using a PID. No elevated PID readings above 1 ppm were observed for any of the onsite SVPs. Additionally, a helium shroud set up was utilized to check for leaks in the seal of the bentonite around each SVP and the tubing/controller connections for each sampling apparatus. WR ensured the recommended shroud ambient helium concentration between 20% and 30% was utilized for each leak detection test, and that no tubing readings for each SVP exceeded a concentration of helium more than 1% of the ambient concentration. A duplicate soil vapor sample was collected from VP-9 by connecting a separate flow controller and summa canister to Hillsborough Street Assemblage: Raleigh, NC WR No. 23-0302 Limited Phase II Environmental Site Assessment September 2023 5 ::WithersRavenel Our People. Your Success. the sample train. A helium leak test was also performed on the duplicate soil vapor sample. See Appendix C for a copy of all field notes, including the soil vapor sampling field forms with helium shroud leak detection test info. Soil vapor samples were collected in laboratory supplied 1-liter Suma canisters with dedicated flow controllers. Following collection, samples were submitted under chain -of -custody protocols to Eurofins - Air Toxics in Folsom, CA for analysis of VOCs by EPA Method TO-15. A copy of the chain -of -custody record is included with analytical data in Appendix B. Soil Vapor Analytical Results - VOCs Laboratory analysis results for the soil vapor samples indicated the presence of targeted VOCs at concentrations above MDLs. Those results are summarized below: • Numerous targeted VOCs were reported at concentrations above MDLs for all soil vapor samples submitted from the subject site. The following VOCs were reported at a concentration that exceeded applicable NCDEQ residential soil gas screening levels (SGSLs): o The reported concentration of chloroform was 15 µg/m3 in soil vapor sample VP-2, which exceeds its residential SGSL standard of 4.1 µg/m3. o The reported concentration of chloroform was 4.5 µg/m3 in soil vapor sample VP-3, which exceeds its residential SGSL standard of 4.1 µg/m3. o The reported concentration of ethylbenzene was 44 µg/m3 in soil vapor sample VP-9, which exceeds its residential SGSL standard of 37.4 µg/m3. o The reported concentration of chloroform was 6.1 µg/m3 in soil vapor sample VP-10, which exceeds its residential SGSL standard of 4.1 µg/m3. o The reported concentration of ethylbenzene was 53 µg/m3 in soil vapor sample VP-10, which exceeds its residential SGSL standard of 37.4 µg/m3. No targeted VOCs were reported above applicable non-residential SGSLs. The analytical results for the soil vapor samples are summarized in Table 3 and shown on Figure 6. A copy of the analytical report is provided in Appendix B. 2.5 Quality Assurance/ Quality Control Soil: A duplicate soil sample was collected from TW-6. The soil sample and the duplicate were collected from the same boring interval and the same macrocore. Both the TW-6 soil sample and the duplicate soil sample were placed in bottleware supplied by the laboratory and transported under chain -of -custody to the laboratory. Both the TW-6 soil sample and the duplicate soil sample were laboratory analyzed for VOCs by EPA Method 8260, SVOCs by EPA Method 8270, RCRA-8 Metals by EPA Method 6020B, mercury by EPA method 7471B, and hexavalent chromium by EPA Method 7199. The laboratory analytical reports were reported to level II QA/QC including the reporting of J-flags (where the laboratory reported concentration is an estimated value greater than the MDL but lower than the reporting limit). The duplicate soil sample results from TW-6 did not exhibit high variability in concentrations when compared to the TW-6 soil sample results. Groundwater: A duplicate groundwater sample was also collected from TW-6. The groundwater sample and the duplicate groundwater sample were collected during the same sampling event. Both the TW-6 groundwater sample and the duplicate groundwater sample were placed in bottleware supplied by the laboratory and transported under chain -of -custody to the laboratory. Both the TW-6 groundwater sample and the duplicate Hillsborough Street Assemblage: Raleigh, NC WR No. 23-0302 Limited Phase II Environmental Site Assessment September 2023 6 ::WithersRavenel Our People. Your Success. groundwater sample were laboratory analyzed for VOCs by EPA Method 6200B, SVOCs by EPA Method 625.1, RCRA-8 Metals by EPA Method 6020B, mercury by EPA method 7470A, and hexavalent chromium by EPA Method 7199. The laboratory analytical reports were reported to level II QA/QC including the reporting of J-flags (where the laboratory reported concentration is an estimated value greater than the MDL but lower than the reporting limit). Slight discrepancies were noted in the analytical data associated with five analytes; however, the differences in analyte concentrations did not exceed 5 µg/L for any one analyte. Additionally, none of the analyte discrepancies were at concentrations that exceeded the NC 2L Standard. Review of the laboratories quality control summary did not identify any analytes of concern that failed the laboratories QA/QC protocol. A few qualifiers were identified in the Matrix Spike, but those qualifiers did not appear to negatively affect the analytical data reported by the laboratory. Soil Vapor. A duplicate soil vapor sample was collected from VP-9. The VP-9 soil vapor sample and the duplicate soil vapor sample were collected during the same sampling event and utilized the same helium shroud and sample train. Different flow controllers were used for each laboratory supplied summa canister. Both the VP-9 soil vapor sample and the duplicate soil vapor sample were laboratory analyzed for VOCs by EPA Method TO-15. The laboratory analytical reports were reported to level II QA/QC including the reporting of J-flags (where the laboratory reported concentration is an estimated value greater than the MDL but lower than the reporting limit). The laboratory report noted that VP-9 and the duplicate sample were analyzed at a dilution due to the presence of high-level non -target species. Efforts were made to ensure that soil gas samples were analyzed with the lowest feasible MDLs under EPA Method TO-15. The duplicate soil vapor sample results from VP-9 did not exhibit high variability in concentrations when compared to the VP-9 soil sample results. 3 Findings, Conclusions, and Recommendations At the request of FRH Realty LLC, WR performed a Limited Phase I I ESA on a ±3.05-acre property addressed as 5200 Hillsborough Street in Raleigh, Wake County, North Carolina. This investigation was initiated to evaluate soil, groundwater, and soil vapor conditions at the subject site relative to the former onsite industrial use of the subject site, a former onsite UST, and adjacent properties with known releases of materials, based on information determined during a Phase I ESA completed on the subject site by WR in May 2022. This assessment was conducted in accordance with the typical assessment requirements of the BRS, though a kickoff meeting has not yet occurred, and no work plan was submitted to the BRS for review prior to the work. Based on the findings of this assessment, WR did not identify the presence of existing USTs on Tracts 1, 2, 7, or 8 of the subject site. No apparent assessment was completed during the removal of the former onsite UST, and therefore, it is possible that residual soil and/or groundwater contamination may be present in localized areas not sampled during this limited assessment. However, based on the results of this assessment, any potential release from the former onsite UST has not caused a large-scale impact to the subject site. WR recommends paying close attention to soils on Tracts 1, 2, 7, and 8 during any future activities for any evidence of odors or staining indicative of a release of petroleum material from the formerly onsite UST. Any petroleum impacted soils discovered during grading will need to be managed in accordance with legal requirements. The highest concentrations of organic compounds and metals identified in the soil, groundwater, and soil vapor samples were entered into the NCDEQ Risk Calculator. The risk calculator was developed by NCDEQ to serve as a tool to help evaluate overall site risk posed by potential contaminants within environmental media. Copies of the input and output sheets for the risk calculator using laboratory analysis results specific to the subject site are provided in Appendix D. Hillsborough Street Assemblage: Raleigh, NC WR No. 23-0302 Limited Phase 11 Environmental Site Assessment September 2023 7 ::WithersRavenel Our People. Your Success. According to the risk calculator results, the highest concentrations of organic compounds and metals detected in site soils do not pose an unacceptable risk to current or future site workers, however they would pose unacceptable risk to potential site residents, construction workers, or trespassers. The highest concentrations of VOCs detected in soil vapor samples do not pose unacceptable risk to residential or non- residential receptors. However, the presence of benzene, 1,2-DCA, naphthalene, and m&p-xylenes at concentrations greater than their respective NC 2L standard would pose an unacceptable risk to all potential receptors who might come into contact with site groundwater. WR recommends the following: - Speaking with an environmental attorney for assistance understanding the risks involved with development of a property with the type of contamination discovered during this assessment. - Submitting this report to the BRS and discussing additional assessment requirements during a future BRS "kickoff" meeting. - Applying to and following the recommendations of the NC Brownfields Program. - Including future design features that prevent occupant access to any contaminated soils. - Avoiding the use of the groundwater beneath the subject site for any reason. - Further evaluating the need for a vapor mitigation system in designs of any future onsite structures. WR is pleased to submit this report describing the limited Phase II ESA activities for the site. This report has summarized the results of WR's field activities and presents the findings of the assessment of existing environmental conditions at the site.

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 (dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. 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. Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and (S) Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the Dilution 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. These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal Limits for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. This column provides a letter and/or number designation that corresponds to additional information concerning the result Qualifier 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. 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" Result (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. A brief discussion about the included sample results, including a discussion of any non -conformances to protocol Case Narrative (Cn) 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 This section of the report includes the results of the laboratory quality control analyses required by procedure or Summary (Qc) 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. This is the document created in the field when your samples were initially collected. This is used to verify the time and Sample Chain of date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This Custody (Sc) 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. This section of your report will provide the results of all testing performed on your samples. These results are provided Sample Results (Sr) 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. C3 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low. Method sensitivity check is acceptable. J The identification of the analyte is acceptable; the reported value is an estimate. J2 Surrogate recovery limits have been exceeded; values are outside lower control limits. J3 The associated batch QC was outside the established quality control range for precision.

Workorder# 2305750 Eleven 1 Liter Summa Canister (100% Certified) samples were received on May 30, 2023. The laboratory performed analysis via modified EPA Method TO-15 using GUMS in the full scan mode. Method modifications taken to run these samples are summarized in the table below. Specific project requirements may over -ride the EATL modifications. Requirement TO-15 ATL Modifications Initial Calibration </=30% RSD with 2 </=30% RSD with 4 compounds allowed out to < 40% compounds allowed out RSD to < 40% RSD Blank and standards Zero Air UHP Nitrogen provides a higher purity gas matrix than zero air Receiving Notes The Chain of Custody (COC) information for samples VP-7, VP-8, VP-9 and VP-10 did not match the entries on the sample tags with regard to sample identification. Therefore the information on the COC was used to process and report the samples. Analytical Notes All Quality Control Limit exceedances and affected sample results are noted by flags. Each flag is defined at the bottom of this Case Narrative and on each Sample Result Summary page. Target compound non -detects in the samples that are associated with high bias in QC analyses have not been flagged. The reporting limit for Ethanol was raised from 2.0 ppbv to 6.2 ppbv due to anomalous linearity in the Initial Calibration. Dilution was performed on samples VP-9 and DUP due to the presence of high level non -target species. Definition of Data Oualifying Flags Eight qualifiers may have been used on the data analysis sheets and indicates as follows: B - Compound present in laboratory blank greater than reporting limit (background subtraction not performed). J - Estimated value. E - Exceeds instrument calibration range. S - Saturated peak. Q - Exceeds quality control limits. U - Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See data page for project specific U-flag definition. UJ- Non -detected compound associated with low bias in the CCV N - The identification is based on presumptive evidence.
