W.Academy Street Cherryville,North Carolina NCD0002787 H&H Job No. MOH-014 1.0 Introduction Hart & Hickman, P.C. (H&H) prepared this Phase II Enhanced Reductive Dechlorination (ERD) and Soil Vapor Extraction (SVE) System Semi-Annual Monitoring Report on behalf of Mohican Mills, Inc. (Mohican) for the former Knitronics facility (NONCD0002787; BF #20051-16-036) located at 1515 W. Academy Street in Cherryville, North Carolina (hereafter referred to as the site). This report serves as a Remedial Action Progress Report (RAPR). A Site Location Map is provided as Figure 1. The general layout of the site, including buildings, pavement, and vegetation, is illustrated on the Site Map provided as Figure 2. This report has been prepared in accordance with a voluntary Administrative Agreement (AA) for a state-directed remedial action executed July 10, 2019, between the North Carolina Department of Environmental Quality (DEQ) Division of Waste Management Superfund Section and Mohican. The signed and notarized DEQ Inactive Hazardous Sites Branch (IHSB) Report Certifications are provided in Appendix A. The Remedial Action Plan (RAP) submitted on June 12, 2020, included the results of remedial action pilot testing and the system designs for soil and groundwater remediation proposed for the site. Soil treatment via the SVE system will mitigate the potential for future vapor intrusion and leaching of contaminants to groundwater. The active groundwater remedy for the site is ERD in the source area. The purpose of ERD injections is to reduce contaminant mass in the groundwater source area such that natural attenuation can proceed for the non- source/downgradient areas of the plume. The goal of the contaminant mass reduction is to reduce source area groundwater concentrations by an order of magnitude. The RAP was approved by DEQ in a letter dated July 24, 2020. 1 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July � • Rpt/Report/PHIIERD_RAPR2 Final.doc h a t}l h i c k m a n SMARTER iW!'.•,+I N SOLUTIONS SVE system installation activities were conducted in general accordance with the RAP between August 2021 and January 2022. A summary of the SVE system installation activities is discussed in Section 5.0, and a detailed description of the SVE system installation activities is presented in H&H's Soil Vapor Extraction (SVE) System Construction Completion Report (CCR) dated June 29, 2022. From November 3, 2020 to November 21, 2020, H&H conducted Phase I ERD groundwater injection activities at the Site. The Phase I ERD event was performed by injecting Terra Systems, Inc. (TSI) SRS®-SD Small Droplet Emulsified Vegetable Oil (EVO) Substrate into 40 injection points near the former wastewater treatment basin. A total of approximately 825 gallons of SRS®-SD concentrate (mixed with approximately 8,250 gallons of potable water, TSI- DC, and sodium bicarbonate and calcium carbonate for pH buffering) were injected into the subsurface. A detailed description of the Phase I ERD injection activities is presented in H&H's Phase I ERD and First Quarterly Remedial Action Progress Report dated May 5, 2021. From September 19, 2022 to October 24, 2022, H&H conducted Phase II ERD groundwater injection activities at the site. The Phase II ERD event was performed by injecting TSI SRS®- SD Small Droplet EVO Substrate into 75 injection points within the eastern portion of the site warehouse building where the dye house was located and areas between the former dye house and the former wastewater basin (Figure 3). An equipment layout schematic is shown on Figure 4. A total of approximately 1,590 gallons of SRS®-SD concentrate (mixed with approximately 15,900 gallons of potable water, TSI-DC, sodium bicarbonate, and calcium carbonate) was injected into the subsurface. A detailed description of the Phase II ERD injection activities and first semi-annual post-injection sampling event conducted in January 2023 is presented in H&H's Phase II ERD Injection and SVE Semi-Annual Monitoring Report dated April 28, 2023. This report includes a summary of the second semi-annual post-injection sampling event conducted in July 2023. Additionally, the report presents operation and maintenance (O&M) activities and off-gas sampling results for the SVE system for the period of operation from April 2023 to September 2023. https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS 2.0 Site Background Information 2.1 Site Location The subject site is a former textile dyeing and finishing facility located on the property currently owned by Mohican Mills, Inc. via merger with Travis Knits, Inc. The property is located at 1515 W. Academy Street, in Cherryville, North Carolina (Figure 1). The facility warehouse building is on a parcel approximately 12.13 acres in size (Figure 2). An adjacent parcel, also owned by Mohican Mills, Inc, contains 4.64 acres consists of undeveloped wooded land to the east of the facility building. Currently, the warehouse building (referred to as the Site building) is occupied by Tire Cord USA and its affiliate Carolina-Pacific Fibers, LLC which are leasing the building for warehouse space. The approximate coordinates of the site are 35' 22' 9.44"N latitude and - 81° 24' 7.13"W longitude. The DEQ Inactive Hazardous Sites Branch (IHSB) reference number for the Site is NCD0002787. 2.2 Land Usage and Zoning The land use in the vicinity of the subject site is primarily residential. Properties located to the west and south are generally residential while properties to the north and east are generally undeveloped. The site and properties to the north are zoned General Manufacturing and Commercial (GMC); and properties to the west, south and east are zoned Residential (R-9, R-19, and R-40). The land surrounding the site in a half-mile radius is a mixture of undeveloped, residential, commercial and industrial properties. The surrounding properties include the following: • North — West Academy Street with undeveloped wooded land and mix of land uses including residential beyond. • South—Residential properties and undeveloped land. • East — Undeveloped wooded land with a Pre-Regulatory Landfill known as Westgate Park Landfill (NONCD0000817); residential properties; and commercial properties beyond. https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS • West—An industrial property with Paul H Beam Road and residential properties beyond. 2.3 Operational History A description of the site operational history and owners is included in the RAP. Briefly, the site formerly operated as textile dyeing and finishing facility with warehouse storage. The site was last operated as a textile facility in 2001 and was sold in 2005 to Mohican Mills as part of an asset transaction. Mohican Mills has used the Site for storage and warehousing. A common compound associated with certain former textile dyeing and finishing operations is the chlorinated volatile organic compound (VOC) tetrachloroethene (PCE). As summarized in the RAP, previous remedial investigations indicate that widespread PCE impacts have been found in soil above the DEQ Protection of Groundwater Preliminary Soil Remediation Goals (PSRGs) and in groundwater above the 2L Standard. The source area is mostly underneath the east side of the Site building and in the area of the former wastewater treatment pit to the east of the Site building. 2.4 Geology and Hydrogeology The geology below the site consists of three layers: the saprolite zone, the partially weathered rock (PWR) zone, and the bedrock zone. These geologic layers are interconnected and no confining units are present. The saprolite consists of unconsolidated clay, silt, and sand with lesser amounts of rock fragments. Due to the range of parent rock types and their variable susceptibility to weathering, the saprolite ranges widely in color, texture, and thickness. The PWR zone, also termed the transition zone, contains highly weathered bedrock that is typically characterized as a zone of high permeability. The bedrock zone is competent but fractured parent rock. In the site area, underlying bedrock is composed of metamorphic rock consisting mainly of mica schist. Soils encountered at the site generally consist of redibrown to tan sandy silt to approximately 55 to 89 ft below ground surface (bgs). PWR, as determined by auger refusal, was encountered at a depth of 55 to 89 ft bgs. Competent bedrock was not encountered during Phase I and II RI assessment activities, but it is likely present just below the PWR zone. https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS 3.0 Groundwater Performance Sampling 3.1 Semi-Annual Post Injection Performance Monitoring Based on the amount of groundwater data collected to date, ERD is effectively treating the groundwater PCE plume. Therefore, semi-annual post-injection performance monitoring is being conducted instead of quarterly monitoring as proposed in the RAP. The first monitoring event was conducted 3 months (January 2023) after completion of the Phase II ERD injection event, and the second monitoring event was conducted 9 months (July 2023) after completion of the Phase II ERD injection event. Historical groundwater elevation measurements, data, and natural attenuation data are presented in Tables 1, 2 and 3, respectively. A matrix summarizing the injection performance monitoring is provided as Table 4. During the second post-injection semi-annual sampling event conducted between July 12 through July 14, 2023, groundwater samples were collected from MW-1, MW-2S, MW-2D, MW-3S, MW-3D, MW-4S, MW-4D, MW-5S, MW-5D, MW-6S, MW-7S, MW-8S, MW-9S, MW-10S, MW-11S, and MW-11D. The wells were purged utilizing a decontaminated bladder pump with dedicated polyethylene tubing and low flow/low stress techniques. Field measurements, including DO, ORP, pH, specific conductivity, ferrous iron, and temperature, were recorded during purging activities at each of the monitoring well locations. Groundwater samples were submitted to Waypoint Analytical, a North Carolina certified laboratory, for analysis of contaminants of concern (COC) VOCs by EPA Method 8260 and the natural attenuation parameter total organic carbon (TOC). For quality assurance purposes, one duplicate sample and one trip blank were also submitted for analysis of COC VOCs by EPA Method 8260. H&H instructed the laboratory to report J-values. Monitoring wells MW-3S, MW-4S, MW-4D, MW-5S, MW-5D, MW-6S, MW-7S, MW-9S, MW-10S, MW-11S, and MW-11D were also analyzed for dissolved gases (methane, ethene, and ethane) using RSK 175 and Resource Conservation and Recovery Act (RCRA) metals. The dissolved gas analysis is primarily to check for ethene which provides evidence of complete PCE https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS reduction while the metals analysis is to check for metal solubilization due to changes in aquifer geochemistry potentially related to the injection. Groundwater sample results are summarized on Table 2, and groundwater field parameters are summarized in Table 3. The low-flow groundwater sampling records are included in Appendix B, and groundwater laboratory reports and chain-of-custody forms are included in Appendix C. 3.1.1 Groundwater Levels Groundwater levels in the monitoring well network were gauged using an electronic water level meter on July 12, 2023 (Table 1). The estimated potentiometric surface maps for the shallow (saprolite) and deeper (bedrock) aquifers for the July 2023 groundwater elevation data are presented in Figures 5 and 6, respectively. The groundwater flow directions in the shallow and deeper aquifers are generally to the east or east-southeast toward an unnamed tributary of Muddy Fork Creek located approximately 700 ft southeast of the southeast corner of the site. This flow direction is generally consistent with prior data. 3.1.2 VOCs The July 2023 groundwater sampling results indicated PCE concentrations in injection area wells decreased or were not detected above the laboratory detection limit in MW-3S, MW-IOS, MW- IIS, and MW-IID and increased slightly in wells MW-6S and MW-9S compared to January 2023 data. MW-6S is located within the site building on the western side of the Phase II ERD injection area. The PCE concentration in MW-6S remains an order of magnitude lower than the pre-injection baseline condition in November 2021. PCE concentrations in MW-6S reduced from 1,560 µg/L in November 2021 to 153 µg/L in July 2023. As indicated in the previous report, PCE concentrations in shallow wells MW-3S, MW-9S, and MW-IOS, located on the eastern side of the Phase II ERD injection area or downgradient of the Phase II ERD injection area, increased between November 2021 and the post-injection sampling events in January and July 2023. However, PCE concentrations decreased in MW-3S and MW- IOS between January 2023 and July 2023. The highest PCE concentration detected in July 2023 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS was 71,500 µg/L in shallow well MW-9S which is situated downgradient of the dye house. The PCE concentration in MW-9S is below its pre-injection concentrations (up to 140,000 µg/L). For wells located outside of the ERD injection areas, there was a continued reduction in the PCE concentrations in monitoring wells MW-2D, MW-3D, MW-4S, MW-4D, and MW-5S and slight increases in PCE concentrations in wells MW-5D and MW-7S compared to the to January 2023 data. The reduction of PCE concentrations in select wells located outside of the injection areas is most likely associated with source area mass reduction resulting from the SVE system and Phase I and II ERD injection events. PCE concentrations in wells located outside of the ERD injection areas will continue to be evaluated on an annual basis (every other semi-annual sampling event). The ERD degradation products trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE), vinyl chloride (VC), and ethene increased in injection area wells between the post-injection sampling events in January 2023 and July 2023. TCE concentrations (up to 28,100 µg/L) increased in MW-3S, MW-6S, MW-9S, and MW-IOS; cis-1,2-DCE concentrations (up to 43,500 µg/L) increased in MW-3S, MW-6S, MW-9S, MW-10S, and MW-11D; VC concentrations (up to 2,710 µg/L) increased in MW-3S, MW-9S, MW-IOS, and MW-11S; and ethene concentrations (up to 1,650 µg/L) increased in MW-3S, MW-9S, and MW-IOS. The continued increase of PCE degradation products (TCE, cis-1,2-DCE, VC, and ethene) following the Phase II ERD injection indicates progression in the PCE reductive dechlorination process to the desired end point which is ethene. These trends indicate that the ERD injections are resulting in enhanced bioremediation in the injection area. Groundwater PCE concentrations detected in the shallow and deeper monitoring wells are shown on Figures 7 and 8. Concentrations of PCE, TCE, cis-1,2-DCE, and VC detected in the shallow source area monitoring wells are shown on Figure 9. The reduction of shallow groundwater PCE concentrations between October 2020 and January 2023 is shown on Figure 10. Graphs depicting the PCE, TCE, cis-1,2-DCE, and VC trends during the pilot test, Phase I ERD and Phase 11 ERD injection events are included in Appendix D. https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS 3.1.3 RCRA Metals To check for metal concentration changes due to changes in geochemistry related to the injection, H&H is monitoring metals in groundwater in accordance with the injection permit. Low concentrations of RCRA metals were detected. Concentrations of arsenic in MW-11 S (14.1 µg/L), and chromium (16.1 µg/L) and lead (30.5 µg/L) in MW-9S exceed their respective groundwater 2L Standards. However, turbidities were elevated in these two wells upon sampling which typically correlates with higher metal concentrations. Historical sample results from MW- 9S (prior to January 2023) and MW-IIS were well below the groundwater standards for these metals. In addition, the lead concentrations in MW-9S decreased from 75.6 µg/L to 30.3 µg/L between the January 2023 and July 2023 post-injection sampling events. Metals concentrations will continue to be monitored in the site wells during future post-injection groundwater sampling events. Chromium was also detected in MW-51) on July 12, 2023 at a concentration of 42.9 µg/L, which is above the 2L Standard of 10 µg/L. H&H suspected the elevated concentrated was a result of elevated turbidity in the well sample or laboratory error considering that chromium was not detected (<0.346 µg/L) when MW-5D was last sampled in January 2023. As a result, H&H resampled MW-51) on September 20, 2023. To rule out turbidity interference, H&H collected both a filtered chromium sample and unfiltered chromium sample. Laboratory results indicated that both chromium and dissolved chromium were not detected (<2 µg/L) (Table 2). Chromium concentrations will continue to be monitored in the specific site wells during future post- injection semi-annual groundwater sampling events. 3.2 Geochemical Parameters A discussion of the field measurements collected for certain natural attenuation parameters and geochemical laboratory results from the July 2023 post-injection sampling event is presented below. Field measurements and laboratory results of the geochemical analyses are also summarized in Table 3, and the laboratory analytical reports are contained in Appendix C. https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS 3.2.1 TOC Because TOC is utilized as an electron donor in the reductive dechlorination process, TOC concentrations provide an indication of the presence and sustainability of the substrate injection. The presence of TOC at concentrations greater than 20 mg/L is considered ideal for biodegradation of chlorinated solvents. During the first monitoring event following the Phase II ERD injection, TOC concentrations were detected above 20 mg/L in MW-3S, MW-9S, MW- IOS, and MW-11S and have remained above 20 mg/L in these wells during the second monitoring event. The available TOC in the injection area shallow wells continues to be favorable for facilitating reductive dechlorination. 3.2.2 Methane The presence of methane indicates anaerobic microbial degradation (methanogenesis) is occurring and reducing conditions have been established which are favorable for reductive dechlorination. Methane concentrations increased in monitoring wells MW-3S, MW-9S, MW- IOS, MW-IIS, and MW-I ID between the baseline sampling event in November 2021 and the post-injection sampling event in January 2023. Between January 2023 and July 2023, methane concentrations have continued to increase. Methane increased from 81.4 µg/L to 407 µg/L in MW-3S, from 2,690 µg/L to 3,220 µg/L in MW-9S, from 2,850 µg/L to 5,950 µg/L in MW-IOS, and from 22 µg/L to 176 µg/L in MW-I I D. These concentrations indicate that strongly reducing conditions have been established in shallow groundwater in the injection area. 3.2.3 Ethane and Ethene The dissolved gases ethene and ethane are the non-toxic end products of reductive dechlorination of chlorinated solvents, and their presence indicates the complete degradation of chlorinated solvents. For PCE, the end product of reductive dechlorination is ethene. Ethene was detected in MW-3S (813 µg/L), MW-9S (1,660 µg/L), and MW-IOS (183 µg/L) in July 2023. These concentrations provide evidence of complete degradation of a portion of the PCE in groundwater in the injection area. https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS 3.2.4 Natural Attenuation Field Measurements Dissolved Oxygen (DO) DO is used by microbes as an electron acceptor for the biodegradation of organic carbon. Reductive dechlorination occurs under anaerobic or low DO conditions. DO concentrations of less than 1 mg/L are favorable for ERD. DO measurements ranged from 0.09 mg/L to 5.95 mg/L in injection area wells MW-3S, MW-6S, MW-9S, MW-IOS, MW-I IS, and MW-11D during the July 2023 post-injection sampling event. Apart from MW-6S, MW-9S, and MW-11D, the measured dissolved oxygen concentrations indicate conditions in the injection area are favorable for reductive dechlorination to occur. pH and Temperature Groundwater pH values ranging from 6 to 8.5 standard units are generally preferable for anaerobic biodegradation. The pH of groundwater affects the presence and activity of microbial populations. Acid generated during reductive dechlorination can decrease pH levels after a bioenhancement injection. The pH ranged from 5.09 to 6.97 in the injection area wells. Certain pH values are below the range considered favorable for reductive dechlorination. The low pH levels in groundwater may limit anaerobic biodegradation processes at the site. The low pH levels are due to naturally occurring conditions and the acids produced by reductive dechlorination process. Temperature does not greatly influence reductive dechlorination, but temperatures greater than 20 C may accelerate biochemical processes. Temperatures ranged from 18.7 C to 22.3 C in the injection area wells. These temperatures are in the range which is considered acceptable for biodegradation. ORP The ORP of groundwater is a measure of electron activity and is an indicator of the relative tendency of a solution to accept or transfer electrons. ORP of a groundwater system affects biodegradation rates. Reductive dechlorination is most efficient in the ORP range corresponding to sulfate reduction and methanogenesis (<-100 mV), but reductive dechlorination also occurs in the ORP range associated with nitrate, manganese, and iron 10 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 � 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS reduction (-50 mV to 740 mV). ORP ranged from -107.2 mV to 105.5 mV in the injection area wells during the July 2023 post-injection sampling event. ORP data are within the range in which reductive dechlorination may occur. 3.3 Quality Control For quality assurance purposes, one duplicate sample (taken at MW-9S) and a laboratory- prepared trip blank were submitted for analysis of COC VOCs by EPA Method 8260 for the July 2023 post-injection sampling event. The duplicate sample contained slightly higher PCE concentrations compared to the target sample. However, TCE, cis-1,2-DCE, trans-1,2-DCE, and VC concentrations were comparable between the duplicate and the target sample. Duplicate samples from other monitoring wells have exhibited varying PCE concentrations in the past which may be related to the sample matrix rather than data quality. The trip blank did not contain detectable concentrations of target VOCs. The quality control data indicate that the data collected are suitable for their intended use. Duplicate and trip blank sample results are summarized in Table 2. 3.4 Investigation Derived Waste Due to elevated compound concentrations near the source area, purge water generated during the July 2023 post-injection semi-annual sampling event of monitoring wells MW-3S, MW-31), MW-5D, MW-6S, MW-7S, MW-9S, MW-10S, MW-11S, and MW-11D was containerized in a 55-gallon drum. A sample was collected from the drum for waste disposal purposes. The drum sample was analyzed for Toxicity Characteristic Leaching Procedure (TCLP) VOCs and TCLP RCRA metals. Laboratory results are provided in Appendix C. Based on the data, the IDW drum was characterized as hazardous waste, profiled, and will be properly disposed at a permitted facility.

The SVE system is split into four well fields: Fields A, B, C, and D. Fields A and B pull air from under the eastern portion of the building. Two SVE wells are located on each well field. Field A consists of SVE-1 and SVE-2; Field B consists of SVE-3 and SVE-4; Field C consists of SVE-5 and SVE-6; and Field D consists of SVE-7 and SVE-8. The piping for each well field extends from the SVE building then splits into individual headers that run to each well. The total depth and screen interval for each SVE well is listed in the table below, and the SVE well locations and final SVE piping layout are shown on Figure 11. SVE Well Well Total Depth Screen Interval ftb s ftb s SVE-1 30 10—30 SVE-2 30 10—30 SVE-3 30 10—30 SVE-4 30 10—30 SVE-5 25 10—25 SVE-6 25 10—25 SVE-7 23 10—23 SVE-8 23 10—23 The well fields are manifolded to an Ametek Rotron® 20 horsepower (hp) explosion-proof regenerative blower. An air/water separator precedes the blower to remove particulates and water from the extracted air. Due to the potential for contaminant concentrations within the condensate water, the air/water separator contains a manually controlled ball valve and flexible piping to discharge the accumulated liquids into two separate 55-gallon drums equipped with level gauges and stored on a 66-gallon secondary containment pallet within the SVE building. The SVE system building as-built diagram is included as Figure 12. 12 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohi an Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS Due to the proximity of the remediation building and SVE off-gas discharge to the Site building (approximately 120 ft), SVE system controls are designed to prevent discharged vapors from reaching the Site building based on ambient wind direction and speed. 4.1 SVE System Performance System O&M activities include regular site visits by H&H personnel to maintain the SVE equipment, improve performance, and for incidental troubleshooting. In addition, H&H periodically checks on system operation via remote online access. System operating parameters are adjusted as necessary to maintain the desired system performance. During the period of system operation between April 2023 and September 2023, the SVE system continued to operate with only brief shut-downs as noted below. No VFD fault alarm conditions were experienced during the current reporting period. During the May and August 2023 O&M site visits, the system was discovered not operating due to a "Communication Timeout" which did not trigger an alarm condition on the Programmable Logic Controller (PLC). As a result, no alarm condition notification was sent to H&H from the PLC. H&H was able to restart the system during both O&M visits and the system appeared to be operating as designed. A PLC technician troubleshooted the system and indicated the condition was likely associated with an electrical interruption. The PLC software was updated by the technician to help remedy the issue. H&H will monitor the communication timeout error and further troubleshoot it as needed. During each monthly O&M visit, the air/water separator is observed for accumulation of water and is manually drained as necessary into a storage drum. Once full, the storage drum will be sampled for characterization,profiled, and properly disposed at a permitted facility. Key SVE parameter data since system start-up are summarized on Table 5, and historical individual wellhead SVE data are included on Table 6. A brief summary and evaluation of the main parameters, including SVE vacuum levels, flow rates, and off-gas vapor concentrations are presented below. 13 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mo i an Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS SVE Vacuum Vacuum levels at the blower have remained at approximately 55 in-WC to maintain approximately 52 to 55 in-WC at the distribution piping headers. This vacuum allows for the blower temperature to remain within the blower operational range without dilution air. The data indicate that only minimal vacuum loss is occurring through the system equipment and piping. SVE Flow Rates SVE air flow rates measured with the flow meter at the equipment building have ranged from approximately 233 standard cubic feet per minute (scfm) to 243 scfm during the current reporting period with the dilution air valve closed and the blower set to approximately 55 in-WC vacuum. The individual well field flow data indicate that the largest portion of the total air flow is coming from Field A, which contains the highest PCE concentrations as mentioned below. The smallest portion of the total air flow is coming from Field B. SVE Vapor Concentrations During each O&M visit, SVE system off-gas discharge concentrations are measured using a photoionization detector (PID) from each of the four well fields (Table 5). The data for the current reporting period indicated that the highest vapor concentrations were present in Field A, with Field D exhibiting the lowest vapor concentrations. A sample of the off-gas discharge vapor was collected on June 16, 2023, for laboratory analysis of VOCs by EPA Method TO-15. The analytical off-gas samples were collected using a 1-Liter Tedlar bag connected to the off-gas discharge. After collection, the bag was sealed per standard procedures and shipped under chain-of-custody record to Eurofins, a North-Carolina certified laboratory. A summary of the TO-15 analytical results is included on Table 7, and the analytical laboratory report is included in Appendix C. The analytical data indicate that the presence of PCE in the off-gas at a concentration of 470,000 micrograms per cubic meter (µg/m3). The concentration is reduced compared to the start-up PCE off-gas concentration of 8,500,000 µg/m3. Methylene chloride was also detected at a concentration of 250,000 µg/m3. Although the lab confirmed the methylene chloride detection, 14 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohi an Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 � Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS H&H is skeptical of the methylene chloride detection and will check for this compound in future off-gas samples. No other constituents in the off-gas samples have been detected above laboratory reporting limits, potentially due to elevated laboratory reporting limits of other compounds as a result of the elevated PCE concentrations. The data indicate that PCE is the primary contaminant being removed by the SVE system, which is consistent with soil and groundwater data. However, other contaminants at lower concentrations are likely also being removed. The data also indicate that off-gas concentrations are declining as mass is removed from the vadose zone. A graph depicting the PCE concentrations over time is included in Appendix E. 4.2 SVE Mass Removal Contaminant mass removal has been calculated using the TO-15 laboratory analytical results (Table 8) and average flow rates for each O&M visit. Note, for visits where TO-15 samples were not collected, an assumed concentration of PCE was used based on the concentration of the previous TO-15 sample. In addition, the discharge flow rate over the specific period between O&M visits was assumed to be consistent between visits. Using the mass removal calculations for the time from start-up (January 12, 2022) to September 19, 2023, approximately 29,028 lbs of PCE (equivalent to approximately 2,100 gallons) have been removed by the SVE system. The estimated September 2023 removal rate is 15.2 lbs/day. As stated above, additional mass removal from other compounds is likely also occurring. Graphs depicting mass removal for PCE overtime and cumulative mass removal are included in Appendix E. 4.3 Ambient Air Testing As discussed in the SVE System CCR dated June 29, 2022, the ambient air within typical breathing space (approximately 5-ft above ground surface) was monitored during system startup and several months thereafter under various wind conditions based on the wind vane anemometer data at the discharge stack and using a hand-held PID capable of reading VOC 15 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 � Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS concentrations in vapor in the parts per billion by volume (ppbv) range. The ambient air monitoring generally included recording measurements from between 50 feet to 200 feet from the discharge stack in the cardinal directions. Further, several additional locations were measured near the Site Building. The ambient air monitoring data are summarized on Table 9, and the locations where measurements were collected are depicted on Figure 11. Evaluation of the ambient air monitoring and the wind speed and direction in the area of the discharge stack indicate the Site building is downwind or crosswind the majority of the time and that most downwind locations do not exhibit detectable levels of VOC vapor concentrations during operation of the SVE system. In addition, if the winds remain sustained in an easterly direction, then the system controls work properly to reduce blower power and open the ambient dilution air valve to reduce the vapor concentrations. Further, the off-gas discharge concentrations have been decreasing since start-up. As such, the SVE discharge does not appear to be increasing VOC concentrations at the building envelop. Because off-gas discharge mass concentrations are decreasing and the risk of increased VOC concentrations at the building envelop has diminished, ambient air monitoring was discontinued in May 2022. While not anticipated, should elevated off-gas discharge concentrations be suspected in the future, ambient air monitoring will be evaluated at that time. 16 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohi an Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS 5.0 Remediation Status Summary Based on the laboratory analytical results for groundwater samples collected during the semi- annual post-injection sampling event in July 2023, significant reductions in concentrations of PCE were observed in injection area wells since implementation of the Phase II ERD remedial action in October 2022. Additionally, concentrations of the degradation products TCE, cis-1,2- DCE, trans-1,2-DCE, and VC increased in monitoring wells near the injection area following the injection. Ethene is also present which is indicative that some contaminant mass has completed the reductive dechlorination process to the desired end point. The laboratory analytical results of the baseline monitoring event will be compared with subsequent post-injection performance monitoring events to further evaluate the Phase II ERD injection event. In accordance with the RAP, an SVE system was installed to mitigate on-going contaminant contributions to groundwater via leaching from the overlying soil and to reduce the VOC mass that may contribute to vapor intrusion. The SVE system was started up on January 17, 2022, and has removed approximately 29,028 lbs of PCE (approximately 2,100 gallons)to date. 17 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS 6.0 Schedule To evaluate the effectiveness of the SRS®-SD injection at reducing VOC concentrations in groundwater, performance monitoring will be conducted semi-annually for two years in accordance with UIC Injection Permit No. WI0300476. The semi-annual monitoring is a reduction over the quarterly monitoring proposed in the RAP and is based on the significant amount of groundwater data collected to date that indicate ERD is effectively treating the groundwater PCE plume. Monitoring reports (aka Remedial Action Progress Reports or RAPRs) will be submitted semi- annually for two years. Therefore, semi-annual sampling will end after the July 2024 sampling event. Each RAPR will be submitted within approximately 90 days of each post-injection semi- annual sampling event and will include groundwater data, SVE system data, copies of laboratory analytical data, summary tables, figures, and other information as appropriate. After two years of semi-annual monitoring, the monitoring will transition to an annual basis depending on the ERD injection results as discussed below. After approximately two years of semi-annual performance monitoring, H&H will review the groundwater results to evaluate if additional injection is warranted. If an additional injection is conducted, it would be followed by additional semi-annual monitoring for approximately one year. If concentrations have been reduced by the Phase I and II ERD injections by an order of magnitude or more, the goal of the RAP would be met. A Final Project Evaluation for the UIC permit will be submitted within nine months of completing injection activities or an interim evaluation will be submitted with a permit renewal application. The final report or interim evaluation will include historical monitoring data, and updated groundwater plume and potentiometric surface maps. O&M activities to maintain the SVE system and collect system parameters will continue on a monthly basis with additional site visits as necessary based on the system operation or potential troubleshooting. The remote telemetry also allows monitoring of the system and the PLC 18 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 � Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS provides automated notifications of system alarm or shut-down conditions. In addition, off-gas vapor concentrations for laboratory analysis will continue to be collected on a quarterly basis and will be used to calculate mass removal rates. Adjustments to the SVE system will be made as necessary during the O&M visits to improve soil vapor removal and system efficiency. Once sustained off-gas readings indicate an order of magnitude reduction in mass, the system may be shut down. 19 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohi an Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS 7.0 Water Supply Well Sampling Water supply wells are situated near the Site, but none are located downgradient of the groundwater plume. Several water supply wells (WSW-1 through WSW-5) have been sampled approximately annually for VOCs by either Mohican or DEQ. A previous arrangement was approved where Mohican and DEQ would sample WSW-1 through WSW-5 on alternating years. DEQ also sampled several additional water supply wells near the site from time to time. To date, five sampling events have been conducted with the most recent event being conducted by DEQ in June 2022. At that time, the wells were also sampled for semi-VOCs by DEQ. No contaminant concentrations related to the Site have been detected in the water supply well samples. Water supply wells WSW-1 are WSW-2 are located cross-gradient of the site. The closest well (WSW-1) is located approximately 225 ft south of the site's southern property boundary (Figure 13). As indicated herein, recent groundwater monitoring data indicate that concentrations are decreasing as a result of source area mass reduction. The PCE concentration in bedrock monitoring well MW-2D located between the source area and WSW-1 has decreased from 21 µg/L prior to the ERD injections in 2017 to only 0.981 µg/L in July 2023. The 2L Standard for PCE in groundwater is 0.7 µg/L, but the Federal Maximum Contaminant Level (MCL) for drinking water is 5 µg/L. Based on the lack of VOC compound detections in the water supply wells, reduction in groundwater PCE concentrations, and the lack of downgradient water supply wells relative to the plume, the potential for Site groundwater to impact water supply wells appears to be little to none. As a result, H&H is proposing to discontinue annual water supply well sampling activities. Should PCE concentrations substantially increase in MW-2D, H&H would recommend re-evaluation of sampling of select water supply wells. 20 https://harthick.shmepoint.com/sites/MwtfFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 202 14 Rpt/Report/PHIIERD_RAPR2 Final.doc h a I}l h i c k m a n SMARTER ENVIRONMENTAL SOLUTIONS Table 1 Summary of Groundwater Elevation Measurements Former Knitronics Facility Cherryville,North Carolina H&H Job No.MOH-014 February 9,2016 February 18,2016 November 1,2016 January 6,2017 Monitoring Total Lithology of Surface Screened TOC Approximate Groundwater Groundwater Groundwater Groundwater Well ID Depth Screened Casing Depth Interval Elevation Screened Interval Latitude Longitude DTW(ft) Elevation DTW(ft) Elevation DTW(ft) Elevation DTW(ft) Elevation (ft bgs) Interval (ft bgs) (ft bgs) (ft msl) (ft msl) (ft msl) (ft msl) (ft msl) (ft msl) MW-1 35 Saprolite N/A 20-35 912.98 878-893 35.36883 -81.40399 29.83 883.15 29.63 883.35 30.36 882.62 31.85 881.13 MW-2S 33 Saprolite N/A 20-35 907.91 873-888 35.36863 -81.40203 26.19 881.72 26.18 881.73 27.95 879.96 28.98 878.93 MW-2D 120 PWR 105 115-120 907.74 788-793 35.36862 -81.40206 25.55 882.19 25.45 882.29 26.15 881.59 27.39 880.35 MW-3S 37 Saprolite N/A 22-37 909.01 872-887 35.36988 -81.40085 30.76 878.25 30.49 878.52 32.78 876.23 34.45 874.56 MW-3D 102 PWR 92 97-102 907.65 806-811 35.36977 -81.40052 30.22 877.43 29.90 877.75 33.25 874.40 34.95 872.70 MW-4S 28 Saprolite N/A 13-28 897.30 869-884 35.37059 -81.39922 21.21 876.09 21.23 876.07 27.16 870.14 28.65 868.65 MW-4D 67 PWR 56 57-67 897.21 830-840 35.37057 -81.39921 21.39 875.82 21.43 875.78 26.54 870.67 28.84 868.37 MW-5S 28 Saprolite N/A 13-28 895.80 868-883 35.36916 -81.39925 20.70 875.10 20.75 875.05 27.12 868.68 27.88 867.92 MW-5D 84 PWR 74 79-84 895.88 813-817 35.36917 -81.39925 20.87 875.01 20.80 875.08 26.51 869.37 27.94 867.94 MW-6S 46 Saprolite N/A 31-46 914.73 869-884 35.36951 -81.40137 NI NI NI NI NI NI NI NI MW-7S 45 Saprolite N/A 30-45 913.12 868-883 35.36984 -81.40175 NI NI NI NI NI NI NI NI MW-8S 43 Saprolite N/A 28-43 898.16 855-870 35.37111 -81.39789 NI NI NI NI NI NI NI NI MW-9S 40 Saprolite N/A 25-40 907.19 867-882 35.36996 -81.40066 NI NI NI NI NI NI NI NI MW-10S 42 Saprolite N/A 27-42 907.23 865-880 35.37001 -81.40054 NI NI NI NI NI NI NI NI MW-11S 39 Saprolite N/A 24-39 907.59 868-883 35.37000 -81.40057 NI NI NI NI NI NI NI NI MW-11D 75 Saprolite N/A 65-75 907.78 832-842 35.37002 -81.40058 1 NI NI NI NI NI NI NI NI Notes: TOC=top of casing;DTW=depth to water from TOC;PWR=partially weathered rock ft bgs=feet below ground surface;MSL=mean sea level;N/A=not applicable;NI=not installed;NM=not measured MW-1 through MW-3D and MW-7S through MW-11 D constructed with lockable flush-mounted well pads.

The O&M shut downs have generally not lasted more than several hours. 4)Total volatile organic compound(VOC)mass is based on analytical samples collected from the off-gas discharge. 5)TO-15 assume concentration is estimated for days when analytical samples were not collected. 6)Calculations assume the off-gas concentrations and flow rates remained consistent from the previous measurements. 7)Organic vapor analyzer(OVA)reading performed with a photoionization detector(PID). 8)Select days include flow rate recorded by remote telemetric monitoring. ppm=parts per million;pg/m3=micrograms per cubic meter;scfm=standard cubic feet per minute;Ibs=pounds;--=not measured Table 8(Page 1 of Page 1) :rm.mia..n.nw�m.�maneam,.are,nw,5n..aoa,�m�w..mM�e,P,ai.+ur.m��e�r.��n-r.oH�moH-o�a.mwm�a zozzmHn eRw��nzozz awnu.uw.w .sv.�em.ae�,osz�z%�. oza - Hart&Hickman,PC Table 9 Summary of SVE System Ambient Air Monitoring Former Knitronics Facility Cherryville, North Carolina H&H Job No. MOH-014 Wind Blower North of Discharge South of Discharge East of Discharge West of Discharge Areas Adjacent to Site Building Wind Discharge Off-gas E-50 NE-70 W-100 Direction Speed Vacuum VFD Dilution Flowrate(6) OVA N-50 N-100 N-150 N-200 S-50 S-100 S-150 (fenceline) (fenceline) W-50 (building) Stairs Tank 1 Fan 3 Fan Clubby SVE-5 SVE-6 Reading (Direction from) (mph) (in-WC) % %open (scfm) (ppm) (ppb) (ppb) (ppb) (ppb) (ppb) SW 4.5-6.3 System off-Baseline 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1/12/2022 SW 4.5-6.3 52 -- 0 0 0 0 0 0 0 0 0 0 0 0 -- -- -- -- -- -- -- S 2.0-3.0 63 82-85 0 -- -- 0 156 600 390 0 0 0 0 0 0 0 0 0 0 45 0 0 0 S-SE 0.1-0.5 60 82-85 0 175 4,659 30 15 6 20 0 5 7 13 6 0 0 -- -- -- -- -- -- -- 1/20/2022 S-SE 0.1-0.5 30 82-85 0 120 1,824 21 10 5 17 0 4 4 12 5 0 0 S-SE 0.1-0.5 30 82-85 0 170 915 20 9 5 8 0 4 4 7 5 0 0 N/NW/NE 1.1-3.2 55 82-85 0 150 3,147 0 0 0 0 0 2 0 0 0 5 7 2/1/2022 N/NW/NE 1.0-4.0 55 82-85 0 -- -- 0 0 0 0 0 0 0 0 0 2 3 N/NW/NE 1.0-4.0 55 82-85 0 -- -- 0 0 0 0 0 0 0 0 0 2 2 2/17/2022 S-SW 5.5-10.5 56 82-85 0 176 2,975 0 0 0 0 0 0 0 0 0 0 0 -- -- -- -- -- -- -- 2/28/2022 S-SE 0.4-1.5 55 82-85 0 197 1,759 256 0 0 0 0 0 0 0 0 17 0 13 79 0 0 0 0 84 S-SW 1.2-4.0 55 82-85 0 200 1,613 33 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 NA 0(3) 55 82-85 0 200 -- 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 j4j E/NE 0.4-2.8 9 30 50(5) 390(6) 175 0 0 0 0 0 0 0 0 0 0 0 0 3 10 30 5 0 0 3/4/2022 E/NE 0.4-2.8 32 60 1 50(5) 460(6) 296 0 0 1 0 0 0 0 0 0 1 0 0 0 1 0 0 20 1 30 5 0 1 0 3/10/2022 N/NE 2.0-3.0 55 82-85 0 150 5,038 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 3/29/2022 S/SW 1.5-4.9 55 82-85 0 -- 1,028 123 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 5/24/2022 N-NE 1.0-3.0 55 82-85 0 230 830 0 0 0 0 72 0 0 0 0 0 0 0 0 0 0 0 0 0 6/22/2022 E/NE 1.0-4.5 55 82-85 0 239 715 7/14/2022 N/NE 0.0-0.5 55 82-85 0 232 547 8/26/2022 S-SW 0.5-1.5 55 82-85 0 230 263 9/20/2022 N-NE 3.0-6.0 55 82-85 0 234 243 10/26/2022 N-NE 1.0-2.0 55 82-85 0 232 1,539 11/28/2022 N-NW 1.5-3.5 55 82-85 1 0 218 383 12/15/2022 N-NE 1.3-3.5 55 82-85 0 217 240 1/19/2023 W/SW/S 5.0-9.0 55 82-85 0 198 144 2/28/2023 NA 3.0-5.5 55 82-85 0 187 129 3/22/2023 S-SW 1.0-3.9 55 82-85 0 230 128 4/25/2023 W/SW 3.0-7.5 55 82-85 0 235 122 5/24/2023 N/NE 2.0-7.0 55 82-85 0 233 170 6/16/2023 N/NW 2.0-7.0 55 82-85 0 238 148 7/13/2023 S/SW 1.0-3.5 55 82-85 0 243 126 8/10/2023 S/SW 2.0-4.8 55 82-85 0 234 70 9/19/2023 N/NE 1.0-3.5 55 82-85 0 235 65 Notes: 1)The soil vapor extraction(SVE)system was started on 1/12/22. 2)Organic vapor analyzer(OVA)reading performed with a parts per billion(ppb)photoionization detector(PID). 3)During the event with no measurable wind,vapor concentrations were detected at 10 feet from the discharge stack at up to 528 ppb. 4)On 3/4/2022,the SVE system automatically opened the dilution air and the blower powered down to 30%power due to sustained easterly winds. 5)Solenoid open full;hand valve closed. 6)Flow rates recorded from influent flow meter at times of no dilution air.On 3/4/22,effluent flow meter was observed to be malfunctioning. Winds were generally variable during each site visit. The OVA values presented indicate the highest PID reading recorded at the corresponding location. OVA readings were generally not sustained for more than 20 seconds in any location. The wind speed and direction were recorded from the installed wind vane anemometer. Locations are recorded as distance in feet from the disharge stack. =not measured;in-WC=inches of water column;VFD=variable frequency drive;ppm=parts per million Table 9(Page 1 of Page 1) hUps://ha hick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills-MOH/MOH-014 Knitronics 2023/PHII ERD/July 2023 RpVTables/Knilronics System Tables_092623.xlsx Hart(fC HICkriJQ/1,PC i 2 Ch. f PST t 5A (d t SITE saE` LIPS PH yyti r�GZ Z` 0 0 w S a U Snne SITE LOCATION MAP 0 2,000 4,OLL 0 v SCALE 111 FEET FORMER KNITRONICS 1515 WEST ACADEMY STREET CHERRYVILLE, NORTH CAROLINA S L U.S.G.S.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA(including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as- received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information. Sincerely, Angela D Overcash Senior Project Manager Laboratory's liability in any claim relating to analyses performed shall be limited to, at laboratory's option, repeating the analysis in question at laboratory's expense, or the refund of the charges paid for performance of said analysis.

Receipt Exceptions The following sample was received in air sample bags: SVE-061623(140-32241-1). EPA Methods TO-14A and TO-15 describe the use of canisters for sampling and analysis,therefore,the use of air sample bags constitutes a modification to the method. Air-GC/MS VOA Methods TO 15 LL,TO-14A, TO-15: EPA methods TO-14A and TO-15 specify the use of humidified "zero air"as the blank reagent for canister cleaning, instrument calibration and sample analysis. Ultra-high purity humidified nitrogen from a cryogenic reservoir is used in place of"zero air"by Eurofins TestAmerica Knoxville. Method Air Transfer: The following sample was received in air sample bags: SVE-061623(140-32241-1). In order to extend the holding times,this sample was transferred from the air sample bags into a Summa canister. No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page.
