2023 GROUNDWATER MONITORING REPORT 1 1.0 INTRODUCTION CES of NC, PLLC (CES) has completed this 2023 Groundwater Monitoring Report (GMR) to document additional environmental assessment activities associated with a confirmed petroleum release from a gasoline transport vehicle accident on State Highway 27 proximal to Lincolnton, North Carolina. This report was prepared on behalf of Energy Dispatch, LLC in accordance with North Carolina Department of Environmental Quality (NCDEQ) correspondence and is being delivered to the NCDEQ Mooresville, North Carolina regional office. 1.1 SITE IDENTIFICATION The incident area is located at 3003 NC Highway 27 East in Lincolnton, NC (site) as indicated on the topographic site vicinity map included as Figure 1. The site is identified by the NCDEQ as Reinhardt Heating and Air Conditioning and above-ground storage tank (AST) incident number 86246. 1.2 SITE DESCRIPTION The site is in a mixed-use area within the jurisdictional limits of Lincolnton, North Carolina. The site is improved with a one-story commercial building currently serving as Reinhardt Heating and Air Conditioning, an active commercial service business. The site further is improved with a gravel parking/access area and chain link fencing. The property is bordered to the west by Nandina Trail and to the south by Highway 27. Residential properties border the subject site to the north and a commercial storage unit facility borders the site to the east. A site map depicting pertinent features of the subject property is provided as Figure 2. 1.3 SITE HISTORY July 2001: On July 17, 2001, a gasoline tanker truck traveling west on Highway 27 overturned proximal to the Reinhart Heating & Air Conditioning facility. The truck came to rest on the north side of Highway 27 with a ruptured gasoline storage tank. As a result, approximately 9,200-gallons of gasoline were discharge to the ground surface. The release followed the topographic gradient to an ephemeral stream that discharged to Hoyle Creek approximately 280-feet south of the release. As part of emergency response activities, a vacuum truck was dispatched to the subject site and approximately 1,650-gallons of free-phase petroleum were recovered. December 2001: As a result of the release, HEPACO, Inc. excavated approximately 175-tons of petroleum impacted material from the southern drainage ditch trending Highway 27. The impacted material was transported off-site for proper disposal and the excavation was backfilled with native fill material. Activities were reported to the NCDEQ by Terraine, Inc. (Terraine) in a Soil Remediation Report dated March 11, 2002. April 2003: In accordance with North Carolina Department of Environment and Natural Resources (NCDENR), directives (now known as the NCDEQ), Terraine completed a Comprehensive Site Assessment (CSA) at the subject site. As part of the CSA, Terraine installed four (4) monitoring wells. Results of the subsequent dissolved-phase sampling event yielded analytical results above groundwater quality standards defined in Title 15A of the North Carolina Administrative Code, Subchapter 2L, Section .0202 (2L Standards), however free product was not detected. 2023 GROUNDWATER MONITORING REPORT REINHARDT HEATING AND AIR CONDITIONING (ENERGY DISPATCH) LINCOLNTON, NORTH CAROLINA AST INCIDENT #86246 REINHARDT HEATING AND AIR CONDITIONING - 2023 GROUNDWATER MONITORING REPORT 2 August 2003: In response to data obtained during CSA activities, a Corrective Action Plan (CAP) was submitted to NCDENR on August 22, 2003. Based on review of the CAP and subsequent pilot study, NCDENR personnel requested that the remedial technique be modified to include periodic Mobile Multi-Phase Extraction (MMPE) events followed by monitoring and natural attenuation. Site specific target levels (SSTLs) also were established for benzene, toluene, ethylbenzene, and xylenes during the CAP phase. February 2004 - July 2006: In accordance with the modified CAP, Terraine conducted six (6) 90-hour MMPE events at the subject site. The MMPE events performed at MW-1 consisted of a sustained negative pressure of approximately 21 inches of mercury (inHg) for a duration of 90-hours. Subsequent sampling events yielded the efficient and effective removal of dissolved-phase contaminants. August 2006: During the August 2006 sampling event, Terraine personnel discovered an additional gasoline tanker had overturned on August 30, 2006. Terraine personnel observed that emergency response measures were being conducted by Spill Group, Inc. (Spill Group). Spill Group indicated that the resulting fire prohibited the calculation of the actual volume released/discharged, however, the tanker reportedly was hauling approximately 9,000-gallons of gasoline. The tankers final location following the incident was immediately west of the Reinhardt Heating and Air parcel. Monitoring well MW-3 was not able to be located during subsequent monitoring events. It is presumed that monitoring well MW-3 was destroyed during the previously mentioned emergency response excavation event. May 2007 A seventh MMPE event was performed May 14 to 18, 2007 by Shamrock Environmental Corporation. Four follow-up sampling events conducted three to fifty days post MMPE indicated exceedances of 2L Standards. July 2007 through May 2010 In accordance with the approved CAP, five groundwater monitoring events were performed to monitor for natural attenuation. Exceedances of 2L Standards continued to persist in site monitoring wells. August 2010: In accordance with NCDENR directives, Terraine mobilized to the subject site on August 31, 2010 to install monitoring well MW-1R. Monitoring well MW-1R was installed following evidence that MW-1 had been destroyed prior to a groundwater monitoring event that occurred in April 2010. April 2011: In accordance with the approved CAP, Terraine mobilized to the subject site to perform a groundwater monitoring event. Terraine collected groundwater samples from monitoring wells MW-1R, MW-2, and MW-4. Terraine was unable to locate monitoring well MW-3, therefore a sample was not collected. Results of the analytical results yielded multiple 2L Standard violations, however, xylenes observed in the sample collected from MW-1R were the only compound that exceeded the SSTLs. October & November 2012: In accordance with the approved work plan, CES initiated chemical and biological injections on October 22, 2012 to stimulate in-situ biodegradation of the observed contaminants. As part of corrective action activities, CES installed four (4) injection wells and injected approximately 5,700-gallons of chemical and biological amendments. Subsequent groundwater monitoring performed on November 15, 2012 indicated significant reduction of dissolved-phase compounds in monitoring well MW-1R. 2023 GROUNDWATER MONITORING REPORT REINHARDT HEATING AND AIR CONDITIONING (ENERGY DISPATCH) LINCOLNTON, NORTH CAROLINA AST INCIDENT #86246 REINHARDT HEATING AND AIR CONDITIONING - 2023 GROUNDWATER MONITORING REPORT 3 January through April 2013: In accordance with the approved work plan, CES remobilized to the subject site on January 7, 2013 to perform an additional biological injection. As part of corrective action activities, CES injected approximately 2,250-gallons of biological amendments. Post injection groundwater monitoring performed on January 30, 2013 indicated a substantial decrease in dissolved-phase compounds in monitoring well MW-1R. An additional groundwater monitoring event performed on April 26, 2013 indicated relatively static concentrations of dissolved-phase compounds when compared to the previous monitoring event. July & August 2013: In accordance with the approved work plan, CES remobilized to the subject site to perform an additional chemical oxidation injection event. As part of corrective action activities, CES injected approximately 2,200-gallons of a 3.0 – 5.0% hydrogen peroxide solution to the network of injection wells. Post injection groundwater monitoring performed on August 22, 2013 indicated a decrease on dissolved-phase compounds. As noted in the October 29, 2013 Groundwater Monitoring Report, additional source area remediation would no longer be possible due to construction of a stormwater retention pond proximal to the former release area associated with a road widening project for Highway 27. In preparation of this project, monitoring well MW-1R and injection wells IN-1, IN-2, IN-3, and IN-4 were properly abandoned. August 2015 through December 2018: Three groundwater monitoring events were performed on roughly an annual basis utilizing the only remaining site monitoring well (MW-2) and/or nearby water supply wells WSW-1 and WSW-2. No exceedances of 2L Standards were reported. Following completion of the Highway 27 road widening project, replacement of monitoring wells MW-1R and MW-4 was suggested. July 2020: After approval of an encroachment permit by the NC Department of Transportation (NCDOT) and issuance of well permits by the NCDEQ Division of Water Resources (DWR), CES installed two replacement groundwater monitoring wells (MW-1R2 and MW-4R) on July 8, 2020. Soil samples collected during installation of the monitoring wells indicated exceedances of the NCDEQ Soil-to-Groundwater maximum soil contaminant concentrations (MSCCs), but no exceedances of the Residential Cleanup Level MSCCs were reported as summarized in Table 1. Groundwater sampling was performed on July 9, 2020 and indicated exceedances of 2L Standards, with total xylenes exceeding the SSTLs. An additional MMPE event was recommended to remediate contaminated groundwater to concentrations below the SSTLs. June 2022: A groundwater sampling event was conducted on June 28, 2022. Laboratory analysis of the groundwater sample collected from monitoring well MW-1R2 continued to yield results above the 2L Standards; however, only the total xylenes concentration exceeded the SSTL. In addition, laboratory analysis of groundwater samples collected from MW-2, MW-4R, WSW-1, and WSW-2 were either below laboratory reporting limits or below 2L Standards. 2.0 RECEPTOR SURVEY CES evaluated potential receptors based on historically available information and current site conditions as discussed below. Historically, Terraine completed receptor survey activities as part of CSA activities. In addition to site reconnaissance performed on August 9, 2012, CES personnel have completed windshield surveys during subsequent site visits to identify potential receptors located within a 1,000-foot radius of the subject property and provided updated receptor information as required. CES confirmed the presence of potential receptors located within the search radius. 2023 GROUNDWATER MONITORING REPORT REINHARDT HEATING AND AIR CONDITIONING (ENERGY DISPATCH) LINCOLNTON, NORTH CAROLINA AST INCIDENT #86246 REINHARDT HEATING AND AIR CONDITIONING - 2023 GROUNDWATER MONITORING REPORT 4 2.1 WATER SUPPLY WELLS Visual inspections were performed for evidence indicating the presence of supply wells/springs. Six (6) water supply wells have been identified within 1,500 feet of the site as summarized in Table 2 and shown on Figure 3. Note that not all identified supply wells are operational. 2.2 PUBLIC WATER SUPPLIES Municipal water service is available to the vicinity of the site by the Lincoln County Department of Public Works under Public Water System ID NC 01-55-035. The source of water is surface water from Lake Norman which is part of the Catawba River basin. No public water supply intakes are located near the site. 2.3 SURFACE WATER The nearest natural surface water body is an unnamed tributary of Hoyle Creek located approximately 300- feet west of the site. An intermittent drainage ditch is located immediately adjacent to the west of the site which also appears to drain into the unnamed tributary of Hoyle Creek. 2.4 WELLHEAD PROTECTION AREA According to the North Carolina Division of Water Quality, the site is not located within an approved wellhead protection area as defined by 42 USC 300h-7(e). 2.5 SURROUNDING LAND USE Land use in the vicinity of the site is primarily residential and commercial. Single family homes are located sporadically in the area with primarily commercial development along the NC Highway 27 corridor. Owners and occupants of adjacent properties have been provided in previous submittals. 2.6 SUBSURFACE STRUCTURES Numerous subsurface utilities are buried in the surrounding area including electric, municipal water, storm sewer, and communications as shown on Figure 2. The burial depths of the subsurface utilities are not expected to intercept the water table. No subsurface structures such as basements or utility vaults have been identified in the vicinity of the release. 2.7 REGIONAL GEOLOGY/HYDROLOGY Based on the published 1985 Geologic Map of North Carolina, the site is located within the Kings Mountain Belt of the Piedmont Physiographic Province. More specifically, the site is underlain by the Blacksburg Formation characterized primarily by metamorphic rocks which consist of sericite schist, graphite, phyllite, quartzite, banded marble, amphibolite, and minor calc-silicate rock. In the piedmont, groundwater is generally accumulated from direct precipitation. Saturated conditions typically occur in the undisturbed primary permeability within the saprolite weathered from the parent bedrock. Groundwater also occurs within secondary permeability of the crystalline bedrock through joints, fractures, and cleavage plains. Groundwater recharge occurs in interstream areas, while discharge is into streams, lakes, and mash areas. 2.8 DEEP AQUIFERS IN THE COASTAL PLAIN PHYSIOGRAPHIC PROVINCE The site is not located within the Coastal Plain Physiographic Province. 2023 GROUNDWATER MONITORING REPORT REINHARDT HEATING AND AIR CONDITIONING (ENERGY DISPATCH) LINCOLNTON, NORTH CAROLINA AST INCIDENT #86246 REINHARDT HEATING AND AIR CONDITIONING - 2023 GROUNDWATER MONITORING REPORT 5 3.0 RECENT SITE ACTIVITIES CES performed groundwater monitoring events at the subject site in March 2023 and in October 2023 in accordance with NCDEQ directives. 3.1 GROUNDWATER SAMPLING CES mobilized to the site on March 30, 2023 and October 19, 2023 for collection of groundwater samples from monitoring wells MW-1R2, MW-2, and MW-4R. Depth to water and total well depth in each monitoring well were measured with an electronic oil/water interface probe. Prior to sampling, a minimum of three well volumes were purged from each well using a dedicated, disposable PVC bailer and nylon cord. The bailer was gently lowered into the well and allowed to fill with water, then raised to the surface and evacuated. This process was repeated until the necessary volume of water had been removed. During purging activities, groundwater physical parameters were recorded by a calibrated groundwater multi- parameter meter at regular intervals. Purge volumes, sample times, and physical parameters recorded during the sampling events are included on the groundwater sampling logs provided in Appendix A. Groundwater samples were also collected from water supply wells WSW-1 and WSW-2 following purging the supply wells for a minimum of 10 minutes. Subsequent to purging the necessary volume of water, groundwater samples were slowly poured from the bailer into laboratory provided containers pre-filled with appropriate preservatives, labeled with indelible ink, entered into chain-of-custody, and immediately placed on wet ice in a chilled cooler maintained at approximately 4° C. The samples were transported under chain-of-custody protocol and submitted to Pace Analytical Services, LLC in Huntersville, NC and Pace Analytical National in Mount Juliet, TN for chemical analysis. The groundwater samples were analyzed for VOCs by Standard Methods 8260/6200, polyaromatic hydrocarbons (PAHs) by Standard Methods 8270, and VPH aliphatic and aromatic carbon chain fractions by MADEP methods. 3.2 GROUNDWATER OCCURRENCE & FLOW DIRECTION On March 30, 2023, measured depth to water in the site monitoring wells ranged from 3.87-feet below top of casing (TOC) in MW-2 to 8.05-feet below TOC in MW-1R2. Groundwater elevations were calculated to range from 90.78-feet in monitoring well MW-1R2 to 96.42-feet in monitoring well MW-2. Based on this data, shallow groundwater flow direction was interpreted to trend towards the southwest as shown on Figure 4A. Groundwater gauging and elevation data is summarized in Table 3. On October 19, 2023, measured depth to water in the site monitoring wells ranged from 15.40-feet below top of casing (TOC) in MW-4R to 15.81-feet below TOC in MW-1R2. Groundwater elevations were calculated to range from 83.02-feet in monitoring well MW-1R2 to 84.69-feet in monitoring well MW-2. Based on this data, shallow groundwater flow direction was interpreted to trend towards the west-southwest as shown on Figure 4B. Groundwater gauging and elevation data is summarized in Table 3. 3.3 ANALYTICAL RESULTS Groundwater analytical results were compared to the 2L Standards and previously determined SSTLs. The March 2023 and October 2023 laboratory analytical reports are provided in Appendix B with groundwater analytical detections summarized in Table 4. Groundwater analytical results from 2023 are also illustrated on Figure 5. Results flagged with a “J” indicate that the analyte was positively identified but the concentration was between the method detection limit and laboratory reporting limit, therefore those values are estimated. Further, results flagged with a “B” indicate that the same analyte was positively identified in the associated blank. 2023 GROUNDWATER MONITORING REPORT REINHARDT HEATING AND AIR CONDITIONING (ENERGY DISPATCH) LINCOLNTON, NORTH CAROLINA AST INCIDENT #86246 REINHARDT HEATING AND AIR CONDITIONING - 2023 GROUNDWATER MONITORING REPORT 6 Laboratory analysis of groundwater samples collected during March 2023 and October 2023 from MW- 1R2 and WSW-1 yielded VOC concentrations above 2L Standards. However, the groundwater samples collected from MW-2, MW-4R, and WSW-2 were reported to be below laboratory reporting limits or below the 2L Standards. Further, no exceedances to the SSTLs were observed during the March 2023 or October 2023 sampling events. Following receipt of the October 2023 laboratory analytical report, CES reported the limited VOC concentrations within WSW-1 to the property owner and the NCDEQ case manager on November 1, 2023. WSW-1 provides water to the Bodylines Towing & Auto Body Repair (Former Downs Garage) facility addressed as 3010 Highway 27 East in Lincolnton, NC. The property owner confirmed WSW-1 is used to provide water to a bathroom and the well is not utilized for potable water. Please note, laboratory analysis of the October 2023 groundwater samples yielded measurable C9-C10 aromatics in MW-1R2, MW-2, MW-4R, WSW-1, and WSW-2. However, these results were flagged with B qualifiers indicating C9-C10 aromatics were observed in the method blank. 3.4 INVESTIGATIVE DERIVED WASTE Purge water generated from the monitoring wells was disposed of on permeable surfaces near the well of generation as a deemed permitted waste in accordance with NCDEQ guidelines. 3.5 QUALITY ASSURANCE & QUALITY CONTROL To reduce the potential of cross contamination, dedicated disposable nitrile gloves were worn during all phases of soil and groundwater sample handling. Field monitoring equipment such as water quality instruments were calibrated to manufacturer specifications prior to each day of use. All samples were maintained under strict chain-of-custody protocol as documented in Appendix B. As part of CES’s quality assurance and quality control (QA/QC) measures, a data review of the laboratory reports was conducted. During the review, it was found that the samples were received by the laboratory in acceptable condition and properly preserved. The samples were analyzed within applicable holding times and the chain-of-custody was properly completed by all parties. The laboratory QC reports show that internal blanks were analyzed for each method that was used for the original samples. The laboratory method blank, laboratory control sample, and associated matrix spike and matrix spike duplicate data results were also provided for each analytical method. Refer to Appendix B for details regarding QA results for the laboratory samples and any noted exceptions. Overall, CES concludes that the laboratory results are of sufficient quality for use in this assessment and any exceptions do not significantly impact the conclusions presented in this report. 4.0 GROUNDWATER MONITORING REPORT SUMMARY Laboratory analytical results from the March 2023 and October 2023 groundwater sampling events exceeded 2L Standards; however, no exceedances were observed above the SSTLs. In fact, exceedances to the SSTLs have not been observed at the subject site since June 2022. It should be noted, limited VOC concentrations were observed within offsite supply well WSW-1 during the 2023 sampling events; however, WSW-1 reportedly only provides water to a bathroom and is not utilized for potable water. The presence of VOCs in WSW-1 was reported to the property owner and the NCDEQ on November 1, 2023. Based on the information presented in this report and the lack of exceedances to groundwater SSTLs for over one (1) year, CES recommends closure of Incident 86246 by filing a Notice of Residual Petroleum for the site and public notice. 2023 GROUNDWATER MONITORING REPORT REINHARDT HEATING AND AIR CONDITIONING (ENERGY DISPATCH) LINCOLNTON, NORTH CAROLINA AST INCIDENT #86246 REINHARDT HEATING AND AIR CONDITIONING - 2023 GROUNDWATER MONITORING REPORT 7 5.0 STATEMENTS AND CERTIFICATION 1 Enter the date the monitoring report was due.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS Results are from sample aliquot taken from VOA vial with headspace (air bubble greater than 6 mm diameter).HS Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated samples may be biased high.L1 The continuing calibration verification was above the method acceptance limit.

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 MDL Method Detection Limit. RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S)Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and 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. 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. 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. 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. 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. 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. V3 The internal standard exhibited poor recovery due to sample matrix interference.
