INTRODUCTION
INTRODUCTION
ERM NC, Inc. (ERM) of Charlotte, North Carolina has conducted the permit -required semi-annual
groundwater monitoring during 2022 at the Toastmaster, Inc., Ingraham Time Products facility located at
17160 Plant Road in Laurinburg, North Carolina. Groundwater at the Site has been impacted by volatile
organic compounds (VOCs), particularly trichloroethene (TCE). The current remedial approach for the
existing groundwater plume is the operation of an extraction and treatment system. The system consists
of three recovery wells through which VOC-impacted groundwater is extracted (pumped) and conveyed to
an above -ground treatment system. The treated groundwater is then re -introduced to the surficial aquifer
via an infiltration gallery. The groundwater extraction and treatment system operates under Non -
Discharge Permit No. WQ0007798, which is effective February 1, 2019 through January 31, 2024.
1.1 Scope of Work
The scope of work for the semi-annual monitoring event included:
■ Measurement of depth to water in eight groundwater monitor wells (MW-3, 5, 6, 7, 9, 10, 11, and 14)
and the subsequent calculation of groundwater elevations in these same wells; and
■ Collection and analysis of groundwater samples from monitor wells MW-7 and MW-14 for VOCs.
2. BACKGROUND INFORMATION
2.1 Site Location
The Toastmaster facility is located at 17160 Plant Road in Laurinburg (Scotland County), North Carolina.
Figure 1 presents a Site location map. A detailed Site map is included as Figure 2. The facility is situated
approximately one quarter of a mile northwest of the intersection of US401 and US15/US501. The
surrounding property land uses are primarily mixed commercial and industrial. The 50-acre property
contains a single building and an adjoining warehouse which are approximately 220,000 square feet in
size.
2.2 Site History & Previous Investigations
The following section presents a summary of historical Site activities and previous investigations. These
details were obtained through a review of historical reports, discussions with facility and corporate
personnel, and historical correspondence.
The Toastmaster facility was originally developed in 1959 as the Ingraham Time Products clock
manufacturing facility. The following provides a summary of previous Site ownership:
1959-1968
Ingraham Company
1968-1980
McGraw Edison Company
1980-1983
Toastmaster, Inc.
1983-1990
Magic Chef, Inc.
1990-Present
Toastmaster, Inc.
The Toastmaster facility ceased active operations in 2002. Between 2002 and 2004, the Site was utilized
as a warehouse. During 2004, all on -site operations ceased. Manufacturing operations formerly
conducted on -site during the lifespan of the facility included the manufacture, assembly, and packaging of
www.erm.com Version: Project No.: 0588976 Client: 29 March 2023 Page 1

BACKGROUND INFORMATION
electrical clocks and timers, waffle bakers, and sandwich toasters. Operations associated with
manufacturing included the following:
■ Plastic molding: where resins are molded into parts using machinery which heats and shapes the
resin into the desired form;
■ Tooling operations: including stamping machines and drill presses;
■ Silk screening: where ink is applied to the clock faces;
■ Chromium and nickel electroplating: Electroplating operations were formerly conducted in
association with the manufacture of metal clock parts;
■ Wood cutting and sanding operations: where wood blanks are formed, cut to size, and sanded;
and
■ Spray and dipping operations: including three dry filter paint booths and one dip tank which are
used to apply finishings to the clock bodies.
An on -site wastewater treatment plant was constructed during initial Site development in 1959. The
wastewater treatment plant was used to treat plating wastewater formerly generated at the plant.
Chromium and nickel electroplating wastewaters were treated to precipitate metals after hexavalent
chromium had been reduced to trivalent chromium. The wastewater treatment plant included two large
concrete settling tanks. Supernatant from the settling process was routed to a large unlined surface
impoundment. Settled solids were spread in an unlined drying bed. Supernatant from the drying beds was
collected and added to the effluent from the settling tank in the unlined surface impoundment. Liquid from
the unlined surface impoundment was discharged to Irvin Creek until 1980, when the discharge was re-
routed to the sanitary sewer system. The wastewater treatment operations were discontinued in 1984 and
the treatment plant underwent a RCRA closure. At that time, Toastmaster voluntarily installed monitor
wells to confirm the absence of groundwater contamination. The monitor wells were sampled by both the
state agency and Toastmaster. According to the Environmental Audit Report prepared by Water and Air
Research, Inc. in 1990, no chromium, cadmium, or cyanide had been detected in the groundwater
samples collected from the wastewater treatment plant area. However, lead, nickel, and zinc were
detected at concentrations substantially above background levels.
A TCE recovery still was operated on the northwest side of the building from the late 1960s until the early
1990s. A fire pit, where the local fire department would practice extinguishing fires, was also located on -
Site to the southwest of the building in the approximate location of the existing groundwater remediation
system. TCE was identified in groundwater at the site in the early 1990s.
A Site Characterization Report (SCR) was prepared by Groundwater Technology in 1991 to define the
lateral and vertical extent of TCE impacted groundwater at the Site. The report indicated the presence of
TCE and associated daughter compounds in the vicinity of the facility and extending to the south and
southwest. Three potential source areas were identified, including:
1) The area along the northwestern side of the plant;
2) An area to the southwest of the plant in the vicinity of the now removed waste treatment system; and
3) The area to the extreme south of the Site where the removed waste treatment system was relocated.
TCE concentrations in groundwater at that time ranged from 25 to 12,000 parts per billion (ppb).
www.erm.com Version: Project No.: 0588976 Client: 29 March 2023 Page 2

3. METHODOLOGY
No significant areas of affected soil have been identified at the Site. During the previous assessment,
nine soil samples were collected from seven locations across the Site and analyzed for TCE using EPA
Method 8010. TCE was not detected at concentrations greater than the laboratory method detection limit
in the soil samples collected. Additionally, free product has not been detected in groundwater at the Site.
A Corrective Action Plan (CAP), prepared by Richard Catlin and Associates, was approved by the North
Carolina Department of Environment and Natural Resources (NCDENR) (currently called the NC
Department of Environmental Quality (NCDEQ)) on July 2, 1993. The CAP focused on mitigation of TCE
in the three potential source areas identified in the 1991 SCR. The overall Site remediation strategy
consisted of the installation of three groundwater recovery wells. Based on the lack of detected TCE in
soils, the proposed Site remedy focused on the recovery and treatment of TCE affected groundwater.
A groundwater treatment system is currently in operation to address the TCE impacted groundwater at
the Site. The groundwater extraction and treatment system operates under Non -Discharge Permit No.
WQ0007798, issued by the NCDEQ, effective February 1, 2019 and will expire on January 31, 2024. The
treatment system includes three recovery wells which discharge to an aeration tank and carbon filtration
system for effluent treatment. At the time of the system design, treated groundwater could not be
discharged to the municipal wastewater treatment plant. Consequently, a 500-foot long infiltration gallery
was constructed along the northwest part of the Site to accept the effluent discharge. Fourteen
groundwater monitor wells exist at the Site. In accordance with the permit, groundwater samples are
collected from two of these wells (MW-7 and 14) on a semi-annual basis to monitor VOC concentrations
at the Site
2.3 Geology & Hydrogeology
The Laurinburg area lies in the Flatwoods section of the Middendorf Formation. Drainage is accomplished
through large, sluggish streams and swampy flood plains. The Middendorf is underlain by the Cretaceous
age Blackwoods Formation, which primarily consists of alternating clay and fine-grained sand layers.
Surficial soils consist of fine- to medium -grained sandy clay mixtures.
The geology beneath the Site is characterized by alternating clay and sand layers and is mapped as
being underlain by several aquifers. Two significant zones of low permeability have been identified at the
Site. The upper aquifer, present at a depth of approximately 15 feet below ground surface, is known as
the surficial sand aquifer. The surficial sand aquifer has maximum thickness of 30 feet in the northern part
of the Site and appears to become thinner towards the south end of the Site. The lower aquifer, known as
the Cretaceous sand aquifer, begins at a depth of approximately 45 to 50 feet below ground surface.
During sampling conducted as part of the SCR, groundwater was encountered between 12 and 17 feet
below the ground surface. Shallow groundwater velocity at the Site was estimated to be 22.1 feet per
year, with a general flow direction of south-southwest.
3. METHODOLOGY
3.1 Groundwater Elevation Measurements
Groundwater monitoring events were conducted on May 10, 2022 and November 29, 2022. Prior to
collection of groundwater samples, static water level measurements were obtained in eight of the Site
monitor wells (MW-3, 5, 6, 7, 9, 10, 11, and 14) using an electronic water level meter. These
measurements were used to establish the depth to groundwater in order to calculate groundwater
elevations and the hydraulic gradient across the Site. The water level meter was decontaminated with an

4. GROUNDWATER MONITORING RESULTS
alconox/water mix and a distilled water rinse between wells. Groundwater levels and their corresponding
elevations are provided in Table 3.
3.2 Groundwater Sample Collection
Groundwater samples collected from monitor wells MW-7 and MW-14 were analyzed for VOCs. Both
wells were purged prior to sample collection using low -flow sampling procedures with a peristaltic pump
(located at the ground surface) and dedicated polyethylene tubing inserted to the approximate mid -point
of each well screen. The monitor wells were purged until field parameters stabilized or until at least three
well bore volumes were extracted.
Field measurements were collected for temperature, dissolved oxygen (DO), pH, oxidation reduction
potential (ORP), specific conductance, and turbidity. Well construction details are presented in Table 1.
Summary tables of field parameter measurements are presented in Table 2. Following purging, samples
were collected in laboratory -provided containers. The samples were placed in chilled, insulated, shipping
containers, and delivered under the appropriate chain -of -custody protocol to Pace Analytical Services,
LLC., a North Carolina -certified laboratory, located in West Columbia, South Carolina. The collected
samples were analyzed for VOCs using EPA Method 8260B.
Groundwater Quality Monitoring Compliance Report Forms (GW-59 and GW-59A) for the 2022 events are
included in Appendix A.
4. GROUNDWATER MONITORING RESULTS
4.1 Groundwater Elevations and Flow
Groundwater flow in the surficial sand aquifer is to the south-southwest under an approximate hydraulic
gradient of 0.012 as measured between monitor wells MW-5 and MW-6. The groundwater flow direction is
consistent with historical observations. Figures 3 and 4 illustrate the groundwater flow directions for the
May and November sampling events, respectively.
4.2 Groundwater Analyses
The results of the May and November 2022 groundwater analyses are summarized in Table 4. TCE and
cis-1,2-dichloroethene (DCE) were the only two VOCs detected during either sampling event. TCE
concentrations exceeded the North Carolina 2L Groundwater Standards of 3.0 pg/L in both MW-7 and
MW-14 during both events, with concentrations ranging from 11 pg/L to 49 pg/L. Cis-1,2 DCE
concentrations were well under its 2L Standard of 70 pg/L.
Figures 5 and 6 illustrate the groundwater analytical results for the May and November sampling events,
respectively. Figures 7 and 8 present isoconcentration maps for TCE, the most prevalent compound in
groundwater, for the May and November 2022 monitoring events. A historical summary of VOC data is
presented as Table 5. Concentration versus time graphs for TCE and cis 1,2-DCE are presented as Table
6. Copies of the laboratory analytical reports for the two monitoring events are included in Appendix B.
5. REMEDIATION SYSTEM OPERATIONS
The on -site groundwater remediation system consists of three recovery wells that are located in the
southeast portion of the Site (RW-1), central portion of the Site (RW-2), and northwest portion of the Site
(RW-3) (see Figure 2). Submersible pumps in each well pump VOC-impacted groundwater via
www.erm.com Version: Project No.: 0588976 Client: 29 March 2023 Page 4

6. DISCUSSIONS AND CONCLUSION
underground lines to an above ground treatment system located in the central portion of the Site,
adjacent to RW-2.
The initial remediation system operated from 1998 to 2020 when it was replaced with newer components.
The new system was started in April 2020 and operates in the same manner as the previous system,
which involves pumping water through a multi -tray air stripper and then through carbon filter media to
absorb residual VOCs. The carbon media is contained within three canisters manifolded together. The
treated groundwater is then pumped via underground piping to a subsurface infiltration gallery located in
the northwest portion of the Site. Treated groundwater percolates into the surficial aquifer under gravity
flow. Approximately 2,427,100 gallons of groundwater were treated from January through December
2022.
Per the discharge permit, influent and effluent samples are collected on a monthly basis and analyzed for
VOCs and pH. Laboratory reports for monthly samples are provided in Appendix C. Analytical results
indicate that VOCs were removed at rates ranging from 67% to 100%. TCE was removed at levels
ranging from 99.6% to 100%. There were no effluent exceedances during 2022.
The remediation system was operational 40% of year, from January through December 2022. The
longest shut down time was between late April and early October (196 days), during which time repairs
were made to an underground system line. The second shut down was between first of November and
mid -December to replace the air stripper discharge pump.
The pH for influent has historically been below the permit required 6.5-8.5, with a range of 5.1 to 6.2
during 2022. Effluent pH was slightly higher, ranging from 5.7 to 6.4. These pH values are considered
background for the shallow coastal plain groundwater. A summary of the monthly results for 2022 are
provided in Table 7.
6. DISCUSSIONS AND CONCLUSION
Groundwater remediation activities during 2022 included the operation of a pump and treat system and
semi-annual sampling of two monitor wells (MW-7 and MW-14) located downgradient of the system
infiltration gallery. The following summarizes data collection and Site activities during 2022:
■ Two VOCs (TCE and cis 1,2-DCE) were detected in groundwater samples collected during the
May and November 2022 monitoring events.
TCE exceeded its 2L Groundwater Standard of 3.0 pg/L in both MW-7 and MW-14, with
the highest concentration in MW-14 at 49 pg/L in November. Overall, TCE
concentrations in MW-7 and MW-14 have been decreasing since 2012.
Cis-1,2-DCE was below the groundwater standard of 70 pg/L in both wells with
concentrations ranging from not detected to 1.1 pg/L.
Groundwater flow directions and hydraulic gradients during the 2022 were generally correlative
with previous monitoring events conducted at the Site. Field parameter values, including pH,
specific conductance, ORP, and temperature are also correlative with past sampling events and
are within realistic ranges for the area.
The remediation system treated approximately 2,427,100 gallons of groundwater during 2022. It
was operational approximately 40% of the time, with the remaining time being shut down on two
occasions: late April to early October to repair an underground system line; and the first of
www.erm.com Version: Project No.: 0588976 Client: 29 March 2023 Page 5

6. DISCUSSIONS AND CONCLUSION
November to mid -December to replace the air stripper discharge pump. There were no effluent
exceedances during 2022.
In accordance with the Non -Discharge Permit (No. W00007798), semi-annual groundwater monitoring
will continue in 2023 and influent/effluent samples will be collected from the remediation system on a
monthly basis. The next groundwater monitoring event is scheduled for June 2023.

If the answer to question 7 is A 'YES'; describe those actions in the space provided below.
If the answer to question 7 is "NO", contact the Regional Office within 90 days; an evaluation may be
required to determine the impact the waste disposal system is having at the review and compliance
boundaries surrounding this facility. Failure to do so may subject the permittee to a Notice of Violation,
fines, and/or penalties.
The site's remedial approach for the existing plume of VOC affected groundwater consists of a series
of recovery wells through which VOC-impacted groundwater is extracted and transferred to an
above -ground treatment system. The treated groundwater is then re -introduced to the surficial
aquifer via an infiltration gallery

S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.

Lot Number: XA20013
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report. Where
sampling is conducted by the client, results relate to the accuracy of the information provided, and as the
samples are received.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or
discussed below.
Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI
scope of accreditation: Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-
dichloroethane) EPA 524.2, E. coli and Total coliforms SM 9223 B-2004, Solid Chemical Material: TOC

Coliform Colilert-18.
If you have any questions regarding this report, please contact the Pace Project Manager listed on the
cover page.
Volatiles
The laboratory control sample (LCS) associated with batch 29118 had bromomethane recovered above
the acceptance limits. This could potentially result in a high bias on analytical results. There were no
detections for this compound in the samples associated with this batch; therefore, data quality is not
impacted.
Inorganic non-metals
The pH analysis associated with the samples in this report were performed after the method
recommended 15 minute holding time.
