INTRODUCTION
INTRODUCTION
ERM NC, Inc. (ERM) of Charlotte, North Carolina has conducted the permit -required semi-annual
groundwater monitoring during 2020 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: 9 March 2022 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: 9 March 2022 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 20, 2021 and November 15, 2021. 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
alconox/water mix and a distilled water rinse between wells.
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 2021 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 0.013 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 2021 groundwater analyses are summarized in Table 4. TCE,
tetrachloroethene (PCE), and cis 1,2-dichloroethene (DCE) were the only three VOCs detected during
either sampling event. The highest concentrations of all three VOCs were detected in monitor well MW-7.
TCE was detected at up to 44 pg/L, PCE was detected at up to 4.9 pg/L, and DCE was detected at up to
1.5 pg/L. The PCE and TCE concentrations exceed their respective North Carolina 2L Groundwater
Standards (21- Standard). The DCE concentrations are 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 2021 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-3), and northwest portion of the Site
www.erm.com Version: Project No.: 0588976 Client: 9 March 2022 Page 4

6. DISCUSSIONS AND CONCLUSION
(RW-3) (see Figure 2). Submersible pumps in each well pump VOC-impacted groundwater via
underground lines to an above ground treatment system located in the central portion of the Site,
adjacent to RW-3.
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 4,291,200 gallons of groundwater were treated from January through December
2021.
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 62% to 100%. TCE was removed at levels
ranging from 97.8% to 100%. There was a TCE effluent exceedance (3.3 tag/L) in October, which was
slightly above the 2L standard of 3.0 pg/L. This exceedance was attributed to spent carbon. The system
was shut down on October 11, 2022 and the carbon was replaced on October 28, 2022 with the system
restarted on the same day. Carbon was also replaced on March 12, 2022. Zebra Environmental of High
Point, NC transported the used carbon to their facility in High Point, North Carolina for proper treatment
and disposal as a non -hazardous waste. Material manifests from both events are provided in Appendix
D.
The remediation system was operational 73% of year, from January through December 2021, with the
longest shut down time between late January and late March (56 days) during which time carbon was
replaced and pumps for the three recovery wells were also replaced. The second longest shut time was
during October, for another carbon replacement effort.
The pH for influent has historically been below the permit required 6.8-8.5, with a range of 5.0 to 5.4.
Effluent pH is slightly higher, ranging from 5.9 to 7.2. These pH values are considered background for
the shallow coastal plain groundwater. A summary of the monthly results for 2021 are provided in Table
7.
6. DISCUSSIONS AND CONCLUSION
Groundwater remediation activities during 2021 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 2021:
■ Three VOCs (TCE, PCE, and cis 1,2-DCE) were detected in groundwater samples collected
during the May and November 2021 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-7 at 44 pg/L in May. Overall, TCE concentrations in
MW-7 and MW-14 have been decreasing since 2014.
PCE exceeded its 2L Groundwater Standard of 0.7 pg/L in MW-7, with the highest
concentration of 4.9 pg/L in November. Overall, PCE concentrations in MW-7 have been
stable since 2014, although a slight increase is noted over the last three monitoring

6. DISCUSSIONS AND CONCLUSION
events. Continued groundwater monitoring will be used to further evaluate this apparent
trend.
Cis-1,2-DCE was below the groundwater standard of 70 pg/L in both wells with
concentrations ranging from not detected to 1.2 pg/L.
■ Groundwater flow directions and hydraulic gradients during the 2021 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 was shut down from late January to late March for the replacement of
pumps in the three recovery wells and also for the replacement of spent carbon. It was again
shut down most of the month of October for an additional replacement of spent carbon.
■ A total of approximately 4,291,200 gallons of impacted groundwater were treated during 2021
with an operational time of approximately 73%.
■ There was one TCE effluent exceedance in 2021, 3.3 pg/L in October, which was slightly above
the 2L standard of 3.0 pg/L. This exceedance was attributed to spent carbon. The system was
shut down immediately for carbon replacement.
In accordance with the Non -Discharge Permit (No. WQ0007798), semi-annual groundwater monitoring
will continue in 2022 and influent/effluent samples will be collected from the remediation system on a
monthly basis. The next groundwater monitoring event is scheduled for May 2022.

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

Volatiles
The continuing calibration verification (CCV) associated with samples -001 and -002 had bromomethane
and chloroethane recovered below acceptance limits. There were no detections for this compound in the
associated samples. A LOQ standard was analyzed and the compound was detected, demonstrating
there was adequate sensitivity to identify the analyte if it were present.
Sample -002 was reanalzyed for trichloroethene due to suspected carryover in initial analysis.
Inorganic non-metals
The pH analysis associated with the samples in this report were performed after the method
recommended 15 minute holding time.
