1.0 INTRODUCTION
On behalf of Osborn, CDG Engineers & Associates, Inc. (CDG) submits this Quarterly Monitoring
Report for the JacksonLea facility in Conover, North Carolina. CDG assists Osborn with sampling
and reporting per the North Carolina Department of Environmental Quality (NCDEQ) Notice of
Regulatory Requirements (NORR) dated June 26, 1998, and the subsequently-issued February 21,
2003, NORR amendment and Acknowledgment of Reciept/NORR dated July 18, 2022. A portion
of the USGS 7.5-minute “Newton, North Carolina quadrangle” topographic map location showing
the site is presented as Figure 1.
2.0 BACKGROUND INFORMATION
In January 1997, a toluene release from the underground storage tank (UST) system was listed as
NCDEQ Incident No. 17439. A Comprehensive Site Assessment (CSA) and Corrective Action
Plan (CAP) were completed to characterize, delineate, and remediate the release. A remediation
system which consisted of soil vapor extraction (SVE), air sparging, and pump-and-treat
technologies was implemented in July 1998. A modified dual phase extraction (DPE) system was
installed in August 2003 to remediate off-site contamination and to replace the former treatment
system(s). The DPE remediation system was designed to recover both groundwater and soil vapors
from existing on-site recovery well RW-2 and off-site recovery well RW-3. The DPE remediation
system replaced the initial pump-and-treat system that was ineffective in capturing the downgradient
portion of the groundwater plume. These activities were conducted by Cooper Environmental.
Eight shallow (Type II) monitoring wells (MW-1A, MW-2A, MW-3 through MW-8) and one deeper
screened (Type III) vertical extent well (VE-1) are currently located on-site, most of which are
utilized for periodic groundwater monitoring in accordance with the NORRs.
The JacksonLea facility has been vacant since 2009 and the manufacturing and warehouse buildings
and support machinery (i.e. air conditioners, air compressors, electrical transformers, toluene
reclamation system, material hoppers, etc.) were demolished and removed in 2012. Although the
major structures and utilities were removed from the site, the remediation system continued
operation using power distributed from a stand-alone electrical service installed after the demolition
began. The water supply well “JacksonLea WSW” had been supplied power distributed from the
Quarterly Monitoring Report CDG Project No. R055723001
JacksonLea Facility September 27, 2023
Incident No. 17439 Page 2
adjacent warehouse. However, due to the water supply well not being used since manufacturing has
ceased, with no planned use for the well in the foreseeable future, no other electrical service has
been installed for the well. Therefore, the well is no longer operational.
CDG conducted a receptor survey update for the site in August and September 2016, as directed by
the NCDEQ. The receptor survey update identified the “Cargo-WSW” located on the down-
gradient adjacent property as the only receptor of concern. The “Cargo-WSW” is sampled at least
annually when operational. The results of the receptor survey were submitted to the NCDEQ in the
Receptor Survey Update Letter dated October 3, 2016.
In May 2019, the DPE remediation system experienced a major system component failure when the
vacuum knockout tank partially collapsed due to metal corrosion. Due to the costs necessary for
replacement of the knockout tank, the age of other major components associated with the DPE
system, and for the purpose of increasing the operational efficiency of the groundwater remediation
system, the remediation system was modified to use submersible pneumatic pumps for groundwater
recovery from recovery wells RW-2 and RW-3. The modifications included the installation of two
pneumatic pumps, one each in recovery wells RW-2 and RW-3, installation of an air compressor in
the system trailer to provide pressurized air for the operation of the pumps, installation and
underground routing of the additional air and fluid lines between the remediation system trailer and
each recovery well, installation of air supply regulators and filters, and reconfiguration of the fluid
lines, strainer, and flow meter that were part of the previous DPE system. The modified
groundwater remediation system began operation on October 11, 2019.
The modified groundwater remediation system no longer employed vacuum vapor extraction as a
component of the remediation, and annual air sampling associated with operation of the previous
DPE system was discontinued. Historical air sampling results from the DPE system don’t indicate a
significant recovery of volatile vapors, and ceasing the vacuum extraction was not expected to
negatively impact site remediation.
Based on the results of two consecutive semi-annual sampling events conducted in December 2021
and June 2022 indicating no analyzed constituents exceeded the North Carolina 15A NCAC 2L (2L)
Standards, CDG recommended deactivating the remediation system to allow confirmation
Quarterly Monitoring Report CDG Project No. R055723001
JacksonLea Facility September 27, 2023
Incident No. 17439 Page 3
groundwater sampling under static conditions. CDG also recommended conducting confirmation
sampling on a quarterly basis to more closely track potential rebound in the concentrations or
migration of the contaminants. The NCDEQ approved the shutdown of the remediation system
and quarterly confirmation sampling in their letter dated July 18, 2022, and the remediation system
was deactivated on August 4, 2022.
Operation and maintenance (O&M) for the remediation system is subcontracted by Osborn to
others when active. Previously, semi-annual sampling events were scheduled to be completed in
May and November by CDG with subsequent reporting to the NCDEQ in June and December of
each year.
3.0 REMEDIAL SYSTEM OPERATION
When operating, the modified groundwater remediation system uses two submersible pneumatic
pumps to recover groundwater, one each in recovery wells RW-2 and RW-3. The pneumatic pumps
are supplied pressurized air from a reciprocating air compressor installed in the remediation system
trailer. The air and fluid lines between the recovery wells and the remediation system trailer are
installed in underground chase pipes that were formerly used for operation of the previous DPE
system. The recovered groundwater from each well enters the remediation system trailer and passes
through a strainer and totalizing flow meter before exiting the remediation trailer through
underground piping which is connected to the City of Conover sanitary sewer system.
Recovery well RW-2 is constructed using 6-inch diameter stainless steel casing with a screened
interval of 30 to 60 feet below land surface (BLS). Recovery well RW-3 is constructed of 4-inch
diameter stainless steel casing with a screened interval of 40 to 60 feet BLS. A bottom-loading
pneumatic pump is installed in each recovery well. The top of the pumps are installed at a depth of
approximately 52 feet BLS and the pumps are approximately 3.5 feet long. Each pneumatic pump is
capable of pumping approximately 4 gallons per minute. Cleaning is routinely performed by others
(contracted by Osborn) to remove sediment and bio-growth buildup within the treatment system
when the system is operating. The modified groundwater remediation system using the pneumatic
pumps began operation on October 11, 2019.

As requested by CDG, the remediation system was reportedly deactivated on August 4, 2022, by the
O&M contractor. The remediation system was confirmed to be inactive by CDG personnel during
the initial quarterly sampling event on August 29, 2022, and remained off through the current
sampling event.
4.0 GROUNDWATER/SYSTEM GAUGING AND SAMPLING
4.1 Groundwater Gauging
On August 16, 2023, CDG gauged the depth-to-groundwater (DTW) in monitoring wells MW-1A,
MW-2A, MW-4 through MW-8, and VE-1 using an electronic water level indicator. DTW
measurements were utilized with top of casing elevations to calculate groundwater elevations in the
gauged wells. Top of casing elevations are relative to each other and based on a common onsite
datum point. The calculated groundwater elevations were used to complete overall groundwater
flow direction interpretation (see Figure 3). Groundwater gauging measurements and calculated
elevations are provided in Table 1. No measurable accumulations of free phase toluene were
detected in the monitoring or recovery wells during the August 16, 2023, sampling event.
4.2 Groundwater Sampling
On August 16, 2023, following gauging of the site wells, CDG collected groundwater samples from
monitoring wells MW-1A, MW-2A, MW-4 through MW-8, and VE-1, and water supply well “Cargo
WSW”. The sampled monitoring wells were purged of at least three well volumes of groundwater
(or until the wells purged dry - for those wells with limited water column and/or slow recharge)
using new disposable bailers prior to sample collection. The water supply well was purged by
opening the spigot and letting the pump operate for approximately fifteen minutes. Following
purging, the groundwater samples were collected in laboratory-provided sample containers, marked
with identifying labels, immediately placed on ice, and delivered under standard chain-of-custody
procedures to Pace Analytical Services, Inc. (Pace) of Huntersville, North Carolina for analyses of
select volatile organic compounds (VOCs) using Standard Method 6200B.

JacksonLea Facility September 27, 2023
Incident No. 17439 Page 5
4.3 Remediation System Sampling
Samples were not collected from recovery wells RW-2 and RW-3 due to the remediation system
being inactive. Additionally, an effluent sample was not collected as no effluent was being
discharged to the City of Conover sanitary sewer system.
5.0 GROUNDWATER/SYSTEM SAMPLING RESULTS
5.1 Groundwater Flow Occurrence
The groundwater potentiometric surface occurs within unconfined water-table conditions above the
top of bedrock in unconsolidated micaceous silt. The dissolved phase toluene impact appears to be
limited to the unconfined portion of the aquifer at this site. Competent and/or fractured bedrock
has not been encountered during previous drilling at the site. DTW in the shallow monitoring wells
ranged from 31.05 to 39.47 feet BLS during the August 16, 2023, sampling event. Table 1
summarizes the well construction and groundwater elevation data. Figure 3 is a groundwater
potentiometric map completed using the August 16, 2023, water level gauging data. The data
indicate an overall direction of groundwater flow primarily toward the east.
5.2 Groundwater Sampling Results
Laboratory analytical results from the August 16, 2023, sampling event (Appendix A) indicate
toluene was detected in monitoring well MW-1A at concentrations exceeding the 2L Standard.
Ethylbenzene and xylenes were also detected in MW-1A, and toluene and ethylbenzene in deep
monitoring well VE-1, at concentrations below the 2L Standards. No analyzed constituents were
detected in the remaining sampled monitoring wells and no analyzed constituents were detected in
the “Cargo WSW” water supply well.
5.3 Remediation System Sampling Results
Remediation system samples were not collected during the August 16, 2023, sampling event as
discussed in Section 4.3.

6.0 CONCLUSION AND RECOMMENDATIONS
The following activities and results occurred during the quarterly sampling period beginning in
August 2022:
The remediation system was shut down on August 4, 2022, to allow for confirmation
sampling under static conditions on a quarterly basis and currently remains off. This
decision was based on sampling data indicating no analyzed constituents exceeded the 2L
Standards during the previous two consecutive semi-annual sampling events conducted in
December 2021 and June 2022.
Toluene was detected at a concentration of 4320 micrograms per liter (µg/l) in source area
monitoring well MW-1A on August 29, 2022, which was the first quarterly sampling event
under static conditions. Toluene was subsequently detected at concentrations of 684, 2040,
2180, and 663 µg/l in MW-1A on a quarterly basis from November 10, 2022, through
August 16, 2023, respectively.
No other analyzed constituents were detected at concentrations exceeding the 2L Standards
during the most recent sampling event.
Analyzed constituents initially increased in monitoring well MW-1A soon after deactivating the
remediation system on August 4, 2022, with toluene exceeding the 2L Standard for the first time
since May 2021. The toluene concentration fluctuated, decreasing then increasing, during the
second and third quarterly events following deactivation of the remediation system and remained
relatively stable from the third to the fourth quarterly sampling events. Toluene decreased in MW-
1A since the fourth quarterly sampling event to a concentration slightly exceeding the 2L Standard
in August 2023. There is an overall decreasing trend in toluene concentrations in MW-1A when
comparing the five quarterly events completed under static conditions. Furthermore, toluene was
not detected in any of the sampled down-gradient monitoring wells. This indicates the toluene
plume currently remains limited to the source area following deactivation of the remediation system.
To continue evaluation the static conditions at the site, CDG recommends continued suspension of
the remediation system and a quarterly sampling schedule. If toluene concentrations begin to show
an increasing trend or there are indications that toluene is migrating off-site, CDG will likely
Quarterly Monitoring Report CDG Project No. R055723001
JacksonLea Facility September 27, 2023
Incident No. 17439 Page 7
recommend re-activating the remediation system or propose another corrective action. Once
analyzed constituents remain below the 2L Standards and are found to be decreasing or stable over
time, CDG will petition for closure of the groundwater incident.
The next proposed quarterly sampling event is scheduled for November 2023 with the report to be
submitted to the NCDEQ in December 2023.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
