Phase II ERD Injection and SVE
Semi-Annual Monitoring Report
Former Knitronics Facility
1515 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. Pursuant to the AA, 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 concentrations by an order of magnitude. The RAP was approved by DEQ in
a letter dated July 24, 2020.

Rpt/PHIIERD_RAPR3.doc
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 third semi-annual post-injection sampling event conducted
in January 2024. 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 October 2023
to March 2024.

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.

Rpt/PHIIERD_RAPR3.doc
 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 red/brown to tan sandy silt to approximately 55
to 89 ft below ground surface (bgs). PWR, as determined by auger refusal, was encountered at
depths 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.

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 source area. 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 and third monitoring events were conducted 9 months (July 2023) and 15
months (January 2024) after completion of the Phase II ERD injection event, respectively.
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 this limited third post-injection semi-annual sampling event conducted on January 22 and
23, 2024, groundwater samples were collected from MW-3S, MW-6S, MW-7S, 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.

The monitoring wells listed above 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
reduction while the metals analysis is to check for metal solubilization due to changes in aquifer
geochemistry potentially related to the injection.

Rpt/PHIIERD_RAPR3.doc

Groundwater sample results are summarized in 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 January 22, 2024 (Table 1). The estimated potentiometric surface maps for the shallow
(saprolite) and deeper (bedrock) aquifers using the January 2024 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 January 2024 groundwater sampling results indicated PCE concentrations in injection area
wells decreased or were not detected in MW-3S, MW-6S, MW-9S, MW-10S, MW-11S, and
MW-11D compared to July 2023 data. For example, PCE has decreased in MW-3S from a high
of 190,000 µg/L in 2019 to 4,310 µg/L (9,750 µg/L in its duplicate sample) in January 2024. In
MW-9S, PCE has decreased from 140,000 µg/L in 2019 to 9,680 µg/L in January 2024. The
highest PCE concentration detected in January 2024 was 9,750 μg/L in the duplicate sample
from shallow well MW-3S.

The ERD degradation products trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE),
vinyl chloride (VC), and ethene are present in groundwater which indicates ERD progression
towards the desired ethene endpoint. TCE concentrations (up to 24,800 μg/L; MW-9S), the cis-
1,2-DCE concentration (39,500 μg/L; MW-9S), VC concentrations (up to 10,800 μg/L; MW-3S)
and ethene concentrations (up to 3,770 μg/L; MW-3S) were detected in January 2024.

Groundwater PCE concentrations detected in the shallow monitoring wells are shown on Figure
7. Concentrations of PCE, TCE, cis-1,2-DCE, and VC detected in the shallow source area

monitoring wells are shown on Figure 8. The reduction of shallow groundwater PCE
concentrations between October 2020 and January 2024 are depicted on Figure 9. Graphs
depicting the PCE, TCE, cis-1,2-DCE, and VC trends during the pilot test, Phase I ERD and
Phase II ERD injection events are included in Appendix D.

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 chromium (up to 46.1
μg/L) and lead (up to 20.3 μg/L) in MW-3S and MW-6S, lead (25.7 μg/L) in MW-9S, and
arsenic in MW-11S (10.1 μg/L) exceed their respective groundwater 2L Standards. However,
turbidities were elevated in these wells upon sampling which typically correlates with higher
metal concentrations which may not be in the dissolved phase. Historical sample results from
MW-3S, MW-9S (prior to January 2023) and MW-11S were below the groundwater standards
for these metals. Metals concentrations will continue to be monitored in the site wells during
future post-injection 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 January 2024 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.

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-
10S, and MW-11S and have remained above 20 mg/L in these wells during the third monitoring
event. In addition, TOC (22.7 mg/L) was detected in January 2024 in the deeper well MW-11D

Rpt/PHIIERD_RAPR3.doc
which is situated within the injection area. The available TOC in the injection area continues to
be favorable to promote biodegradation by 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-
10S, MW-11S, and MW-11D between the baseline sampling event in November 2021 and the
post-injection sampling event in January 2023. Between January 2023 and January 2024,
methane concentrations have continued to increase. Methane increased from 81.4 μg/L to 4,720
μg/L in MW-3S, from 2,690 μg/L to 5,260 μg/L in MW-9S, from 2,850 μg/L to 11,200 μg/L in
MW-10S, from 8,690 μg/L to 12,700 μg/L in MW-11S, and from 22 μg/L to 366 μg/L in MW-
11D. These concentrations indicate that strongly reducing conditions have been established in
shallow and deeper 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 (3,770 μg/L), MW-9S (1,210 μg/L), MW-10S (785
μg/L), and MW-11S (125 μg/L) in January 2024. These concentrations provide evidence of
complete degradation of a portion of the PCE in groundwater in the injection area.

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 0.0
mg/L to 6.83 mg/L in injection area wells MW-3S, MW-6S, MW-9S, MW-10S, MW-11S, and
MW-11D during the January 2024 post-injection sampling event. Apart from MW-3S, MW-

9
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills - MOH/MOH-014 Knitronics 2023/PHII ERD/April 2024
Rpt/PHIIERD_RAPR3.doc
6S, and MW-9S, 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 5.13 to 6.77 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 13.3 C to 18.3 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
reduction (-50 mV to 740 mV). ORP ranged from -116.4 mV to 145.8 mV in the injection area
wells during the January 2024 post-injection sampling event. ORP data are within the range in
which reductive dechlorination may occur.

Rpt/PHIIERD_RAPR3.doc
3.3 Quality Control

For quality assurance purposes, one duplicate sample (collected from MW-3S) and a laboratory-
prepared trip blank were submitted for analysis of COC VOCs by EPA Method 8260 for the
January 2024 post-injection sampling event. The duplicate sample contained higher PCE, TCE,
cis-1,2-DCE concentrations. 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. H&H
believes that the data collected are suitable for their intended use. The duplicate 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
January 2024 post-injection semi-annual sampling event of monitoring wells MW-3S, MW-6S,
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 drum will
be transported off-site for disposal prior to the next semi-annual sampling event, and the disposal
manifest will be provided in the next semi-annual report.

As outlined in the last report, the IDW drum generated during the July 2023 sampling event was
transported off-site for disposal as characteristically hazardous waste on October 9, 2023. The
IDW disposal manifest for this drum received after submittal of the last semi-annual report is
included in Appendix E.

4.0 SVE System Operation

The SVE system construction was completed in January 2022 with system start-up beginning on
January 12, 2022. 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 are listed in the table below,
and the SVE well locations and final SVE piping layout are shown on Figure 10.

SVE Well Well Total Depth
(ft b s)
Screen Interval
(ft b 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 11.

4.1 SVE System Performance

System O&M activities include monthly 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 October 2023 and March 2024, the SVE system continued to operate
with only a brief planned shut-down as noted below.

To evaluate whether soil gas VOC concentrations would rebound if the system shut down for an
extended period of time, an evaluation was conducted in October 2023. Specifically,
immediately following the October 9, 2023 quarterly SVE system off-gas sample collection, the
SVE system was shut down for an approximate three-week period of time. On October 30,
2023, the SVE system was restarted. Approximately one week later on November 9, 2023, an
SVE system off-gas sample was collected. As shown in Table 7, the VOC concentrations
detected in the off-gas samples collected on October 9, 2023 and November 8, 2023 were
similar. As a result, it does not appear that significant soil gas VOC concentration rebounding
occurs when the SVE system shuts down for a short period of time. SVE system off-gas sample
results are discussed further below.

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.

SVE Vacuum
Vacuum levels at the blower have remained at approximately 55 to 60 in-WC to maintain
approximately 53 to 58 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 178 standard cubic feet per minute (scfm) to 240 scfm during the current
reporting period with the dilution air valve closed and the blower set to approximately 55-60 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 indicate that the highest vapor concentrations were present in Field A,
with Field D exhibiting the lowest vapor concentrations.

Samples of the off-gas discharge vapor was collected on October 8, 2023, November 8, 2023,
and February 13, 2024 for laboratory analysis of VOCs by EPA Method TO-15. As noted
above, the November 8, 2023 sample was collected to evaluate soil gas VOC concentration
rebounding associated with system shutdowns. 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 for
analysis. 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 the presence of PCE in the October 8, 2023, November 8, 2023, and
February 13, 2024 off-gas samples at concentrations of 720,000 micrograms per cubic meter

14
https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills - MOH/MOH-014 Knitronics 2023/PHII ERD/April 2024
Rpt/PHIIERD_RAPR3.doc
(µg/m3), 760,000 µg/m3, and 1,200,000 µg/m3, respectively. The concentrations are 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 32,000 µg/m3 in the October 8, 2023 off-gas sample. 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 off-gas concentrations over time is included in Appendix F.

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. For visits where TO-15 samples were not
collected, an assumed concentration of PCE was used based on the concentration of the most
recent 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 March 12,
2024, approximately 32,102 lbs of PCE (equivalent to approximately 2,400 gallons) have been
removed by the SVE system. The estimated March 2024 removal rate is 24.7 lbs/day.
Additional mass removal from other compounds may also be occurring. Graphs depicting mass
removal for PCE overtime and cumulative mass removal are included in Appendix F.

4.3 Previous 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.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Mohican Mills - MOH/MOH-014 Knitronics 2023/PHII ERD/April 2024
Rpt/PHIIERD_RAPR3.doc
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,

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 have not exhibited 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.

5.0 Remediation Status Summary

Based on the laboratory analytical results for groundwater samples collected during the semi-
annual post-injection sampling event in January 2024, 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 32,102 lbs of PCE (approximately 2,400 gallons) to date.

6.0 Schedule

To evaluate the effectiveness of the SRS®-SD injection at reducing VOC concentrations in
groundwater, performance monitoring is being 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) are being submitted semi-
annually for two years. With this schedule, 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, the source area groundwater remediation 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

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.

7.0 Previous 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
g/L prior to the ERD injections in 2017 to only 0.981 g/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 low. As a result and with DEQ approval in a January 10, 2024 letter, annual water
supply well sampling activities have been discontinued. Should future PCE concentration trends
substantially increase in MW-2D, H&H would recommend re-evaluation of sampling of select
water supply wells.

Project: MOH-014 Lab Report Number: 24-024-0010
Date: 2/9/2024
Metals Analyses Method 6020B Sample 95169 (MW-9S) QC Batch No: L732064/L730693 Based on sample screening, a dilution was performed due to high levels of target and/or non-target analytes. Reporting limits have been adjusted accordingly.
Volatile Organic Compounds - GC/MS Method 8260D
Sample 95166 (MW-3S) QC Batch No: V43294/V43122
The analysis for this sample was performed outside the EPA required holding time. Original sample ran within hold time. Dilution ran outside of hold. Data matches.
Sample 95170 (MW-10S)
QC Batch No: V43294/V43122 The analysis for this sample was performed outside the EPA required holding time.
Original sample ran within hold time. Dilution ran outside of hold. Data matches.
Sample 95169 (MW-9S) QC Batch No: V43294/V43208
The analysis for this sample was performed outside the EPA required holding time. Original sample ran within hold time. Dilution ran outside of hold. Data matches. Sample 95173 (GW-DUP)
QC Batch No: V43314/V43312 Sample was ran in hold, but due to matrix interference, internal standards were surpressed. This in turn caused
surrogates and analytes related to those internal standards to be elevated. A dilution was ran out of hold which saw internal standards and surrogates return to normal levels.

Dear Steve Libbey:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 1/24/2024 for the analyses presented in the
following report.
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

ReceiptThe sample was received on 2/14/2024 at 9:30am and arrived in good condition.
Receipt ExceptionsThe Field Sampler was not listed on the Chain of Custody.
The following sample was received in air sample bags: SVE-021324 (140-35529-1). EPA Methods TO-14A and TO-15 describethe use of canisters for sampling and analysis, therefore, the use of air sample bags constitutes a modification to the method.
Air - GC/MS VOAMethods TO 15 LL, TO-15: EPA methods TO-14A and TO-15 specify the use of humidified "zero air" as the blank reagent forcanister cleaning, instrument calibration and sample analysis. Ultra-high purity humidified nitrogen from a cryogenic reservoir isused in place of "zero air" by Eurofins TestAmerica Knoxville.
Method Air Transfer: The following sample was received in air sample bags: SVE-021324 (140-35529-1). In order to extend theholding 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.

Receipt
The sample was received on 11/9/2023 at 9:15am and arrived in good condition.
Receipt Exceptions
The following sample was received in air sample bags: SVE-110823 (140-34292-1). 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
The following samples were received in air sample bags: SVE-110823 (140-34292-1) and SVE (110823) (500-242279-1). In order to
extend the holding times, these samples were transferred from the air sample bags into Summa canisters.
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.
Methods TO 15 LL, TO-15: The continuing calibration verification (CCV) associated with batch 140-80134 exhibited % difference of > 30%
for the following analyte(s): Vinyl acetate; however, the results were within the LCS acceptance limits. The EPA method requires that all
target analytes in the continuing calibration verification standard be within 30% difference from the initial calibration. According to the
laboratory standard operating procedure, the continuing calibration is acceptable if it meets the laboratory control sample acceptance
criteria.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Receipt
The sample was received on 10/10/2023 at 10:00am and arrived in good condition.
Receipt Exceptions
The following sample was received in air sample bags: SVE-100923 (140-33915-1). 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
The following sample was received in air sample bags: SVE-100923 (140-33915-1). In order to extend the holding times, this sample
was transferred from the air sample bags into a Summa canister.
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 TO-15: The continuing calibration verification (CCV) associated with batch 140-78795 exhibited % difference of > 30% for the
following analyte(s): Vinyl acetate; however, the results were within the LCS acceptance limits. The EPA method requires that all target
analytes in the continuing calibration verification standard be within 30% difference from the initial calibration. According to the laboratory
standard operating procedure, the continuing calibration is acceptable if it meets the laboratory control sample acceptance criteria.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
