Re: Remedial Action Progress Report, 2023 Third Quarter
Former Seaboard Chemical and Riverdale Drive Landfill Site
Jamestown, Guilford County, North Carolina
Dear Mr. Aufderhaar:
The Seaboard Group II and the City of High Point are providing this 2023 Third Quarter Remedial Action
Progress Report for the former Seaboard Chemical Corporation facility and the closed Riverdale Drive
Landfill located in Jamestown, NC.
During the third quarter of 2023, the mechanical and phytoremediation treatment systems processed
3,755,987 gallons of extracted groundwater and leachate. Based on the average influent contaminant
concentrations, approximately 268.8 pounds of volatile organic compounds and 22.8 pounds of 1,4-
dioxane were recovered from the groundwater extraction wells and leachate collection systems.
One major and one minor shutdown occurred during the third quarter of 2023. The system was shutdown
for 7 days beginning on September 5, 2023 for a routine citric acid cleaning. The system was also
shutdown on September 23, 2023 for 1.6 days related to a power failure. No other significant shutdowns
occurred during this reporting period.
The irrigation line replacement is complete and fully operational. Each irrigation zone is capable of
managing the full design volume of irrigation water from the mechanical treatment system.
Also, please find attached the TM -I I Fourth Quarter and Final Summary Report for groundwater samples
collected on July 6, 2023 at the Pond 3 and SIS Basin Areas.
Please contact Craig Coslett (610/435-1151) or Gary Babb (919/605-4719) if there are any questions or
comments regarding this update.

1.0 BACKGROUND
In April 2020, the Seaboard Group II and City of High Point (Parties) submitted the Remedial
Monitoring and Effectiveness Evaluation (RMEE) Report that documented the initial two years
of operation, maintenance, and monitoring of the extraction and treatment system for the former
Seaboard Chemical and Riverdale Drive Landfill Site (Site). A recommendation provided by the
RMEE Report was to evaluate the shallow groundwater interactions within the Southern
Intermittent Stream (SIS) Area.
The evaluation of the SIS Area, performed during the spring and summer of 2021, included an
evaluation of the existing extraction system, contaminant source areas, and capacity of the
current treatment system. The objective of the SIS evaluation was to determine if modifications
to the existing extraction system could improve the removal of contaminant mass while
maintaining operations to meet the requirements described in the Remedial Action Settlement
Agreement (RASA). This evaluation included:
• Installation and sampling of additional assessment monitoring wells in the SIS basin area,
• Drawdown tests of the existing extraction wells in the area of the SIS basin, and
• Yield testing of select existing wells on the Seaboard property near the former Pond 3.
Based on this evaluation, modifications to the existing groundwater extraction treatment system
were developed to improve the removal of contaminant mass from groundwater and further
protect the surface water quality of the SIS and Randleman Lake as described in the RASA.
The specific modifications, which were the basis for Technical Meorandum-11 (TM-11),
included the following activities:
1.1 Former Pond 3 Area
A review of the annual water quality monitoring data indicated an area of high contaminant
concentrations downgradient of the former Pond 3 at the Seaboard property. This pond was
subject to RCRA closure in the late 1980s which included a final concrete cap (Figure 1).
-1-

Two wells near Pond 3 were considered for further evaluation as part of this effort. Water
quality data collected from monitoring well PW-SF 1 had reported significant concentrations
of volatile organic compounds (VOCs) and 1,4-dioxane on a consistent basis. Also, when
the SCC facility was in operation during the 1980s, well R-1 was operated as an extraction
well on a limited basis. The location of these two wells is shown on Figures 1 through 3. A
review of files on the NC DEQ website located a construction schematic for the former
extraction well R-1. The well construction information for both R-1 and PW-SF 1 is provided
in Appendix A.
To assist in determining adequate treatment capacity, a yield test and sampling event were
performed for wells R-1 (60' depth) and PW-SF1 (120' depth) on August 24, 2021.
Pumping was gradually stepped up until the maximum volume of water could be extracted
while maintaining a stable water level. It was determined that well R-1 would yield
approximately 1-1.5 gpm and well PW-SF1 would yield approximately 6 gpm on a consistent
basis.
1.2 SIS Basin Area
To further assess groundwater conditions and interactions between the shallow groundwater,
landfill leachate and surface water at the SIS Basin Area, four additional monitoring wells
were installed on March 19-20, 2021. Three of the wells were installed as Type II saprolite
monitoring wells (AW-2, AW-3, and AW-4) while the fourth well was installed as a Type III
bedrock well (AWB-4). These four new monitoring wells along with other wells in the SIS
Basin Area were sampled to provide a snapshot of contaminant concentration in the shallow
and deeper portions of the aquifer. The locations of the groundwater monitoring and
extraction wells in the SIS Basin Area are shown on Figure 4.
In addition to the sampling and analysis of monitoring wells in the SIS basin Area,
drawdown tests were conducted using existing extraction wells PW-DR1 and RW-SIS1.
These tests were conducted independently in each extraction well after water levels had
stabilized to non -pumping conditions. The approximate radius of influence for each of
extraction well was then determined for the shallow and deeper groundwater aquifer.
-2-

The contaminant concentrations and observed radius of influence from the existing extraction
and monitoring wells suggested that additional extraction of the shallow groundwater in the
SIS basin area would be beneficial as required by the RASA. To improve capture,
replacement of existing extraction well RW-SIS I and one new proposed extraction well
(RW-SIS7) were completed. The location and screened interval for the original RW-SIS1
well were believed to be ideal for extraction but yield tests indicated too low of yield. The
replacement well was installed adjacent to the original well location and increased the
screened interval, IE across the full thickness of the saprolite aquifer. The new extraction
well RW-SIS7 and replacement well for RW-SIS1 (RW-SIS8) are installed on the opposite
sides of the SIS basin. Both new extraction wells were installed to a depth of 50' and
completed with a 6" diameter PVC casing and screened from 10' - 50'. The locations of the
new extraction wells are shown on Figure 4 and Well Construction Records for the two new
wells are provided in Appendix B.
-3-

2.0 TM-11IMPLEMENTATION
The Parties submitted TM -II to the NC DEQ on February 2, 2022, which was conditionally
approved on February 18, 2022. A response to the conditions was submitted by the Parties to the
NC DEQ in a letter dated February 24, 2022, which resulted in full approval on March 8, 2022.
A summary of the field work completed during the implementation of TM -I I is provided below:
2.1 Extraction Well Installations
During March 2022, two new extraction wells were installed at the SIS Basin Area to provide
for additional extraction in the saprolite/shallow bedrock zone.
• Groundwater extraction well RW-SIS7 was completed to a depth of 50' below land
surface and screened from 10'-50'. This well produces approximately 4 - 7 gpm which
creates a significant capture zone in the southern SIS Basin Area.
• Groundwater extraction well RW-SIS8 (replacement for RW-SIS1) was also completed
to a depth of 50' below land surface and screened from 10'-50'. This extraction well is
producing less than 1 gpm resulting in a drawdown of approximately 20' below static.
2.2 Extraction Well Pump Installation and Performance
The two new extraction wells at the SIS Basin Area (RW-SIS7 and RW-SIS8) and the two
existing extraction wells at the Pond 3 Area (R-1 and PW-SF1) were equipped with QED
AP4 pneumatic pumps in June 2022. These pumps are supplied with compressed air and are
controlled by a float switch which actuates the pumping cycle. Following installation,
extraction well yields were determined based on pump cycles as follows. The variability is a
result of mechanical and environmental factors.
• RW-SIS7 4-7 gpm
• RW-SIS8 0.5-1 gpm
• R-1 0.5-1 gpm
• PW-SF1 4-5 gpm

3.0 FOURTH QUARTERLY ANALYTICAL RESULTS
The fourth quarterly groundwater monitoring event for the expanded extraction system was
completed on July 6, 2023. The field parameter and groundwater elevations are summarized on
the enclosed Table 1. A summary of the laboratory analytical results for the former Pond 3 and
SIS Basin Areas is provided on the enclosed Table 2. The laboratory analytical report is
included with this report in Appendix C. A summary of the fourth quarterly observations is
provided below:
3.1 Former Pond 3 Area
The capture zone created by extraction wells R-1 and PW-SF1 (Figure 1) has remained
consistent over the four quarterly monitoring events with only minor fluctuations. The
drawdown created by the pumping of recovery wells R-1 and PW-SF1 is controlling
groundwater flow on the eastern portion of the former Seaboard property. The operation of
the groundwater extraction system at Pond 3 has dewatered the shallow aquifer above the
bedrock zone as evident by dropping the groundwater level below the screened interval in
monitoring wells MW-7A and W-12A. The groundwater extraction system has removed an
average of 136,600 gallons/month over the past year at the Pond 3 Area.
The observed total VOC concentrations indicate a gradual decreasing contaminant trend over
the four quarterly monitoring events as shown on Figure 2.
The 1,4-dioxane concentrations are shown on Figure 3. They indicate a stable and slightly
decreasing contaminant trend. The highest concentration of 1,4-dioxane at the Pond 3 Area
is present in monitoring well MW-7B. This well is located immediately downgradient of
Pond 3 and is within the influence of the extraction system as noted by the dewatering of
MW-7A, which is paired with MW-7B.
Over the initial year of operation, the extraction system at the Pond 3 Area (R-1 and PW-
SF1) has removed 5,062 pounds of volatile organic compounds and 206 pounds of 1,4-
dioxane. The following chart illustrates the mass removal over the 12-month evaluation
period:

The continued operation of the extraction system at the Pond 3 Area is expected to have a
beneficial effect on downgradient groundwater and surface water quality in the SIS drainage
basin.
3.2 SIS Basin Area
The capture zone created by extraction wells RW-SIS7 and RW-SIS8 as shown on Figure 4
is consistent with the observations made during the previous quarterly events. The SIS Basin
extraction system targets the saprolite/shallow bedrock aquifer (screened 20' — 50' bls) and
has not shown significant influence from the deeper bedrock extraction well PW-DR1
(screened 40' — 185' bls) which is located approximately 40' north/northeast of RW-SIS8
(Figure 4). The groundwater extraction system at the SIS Basin Area has removed an
average of 205,600 gallons/month over the past year.
The objective of the expanded extraction system at the SIS Basin Area is twofold; 1) improve
surface water quality at the SW-4 location and, 2) reduce contaminant concentrations in well
pair AW-3/AWB-4. Periodic surface water sampling of the SIS discharge has shown a
significant improvement in water quality during operation of the expanded extraction system,
as shown below:

SW-3: SIS Pipe Outfall to Basin
SW-4: SIS Pipe Inlet
SW-5: SIS Upstream
The contaminant "spikes" noted in the SW-4 sample results on 11/22 and 5/23 have been
determined to represent inefficiencies in operation of the RW-SIS7 pump. The pump and
discharge line in RW-SIS7 have been susceptible to iron fouling which limits the extraction
rate. A routine monthly cleaning of this pump has been implemented to address the iron
fouling. The contaminant spikes are indicative of needed maintenance which has also
confirmed the benefit, at least initially, of including the new well into the collection system.
The operation of the expanded extraction system at the SIS Basin Area has created a capture
zone which extends in a downgradient direction to include the AW-3/AWB-4 well pair. As
shown on Figure 7, the operation of extraction well RW-SIS7 controls shallow groundwater
flow in the SIS Basin. As further discussed below, this has resulted in a reduction in
contaminant concentrations in the AW-3/AWB-4 well pair.
The total VOC and 1,4-dioxane analytical data trends at the SIS Basin Area show a stable to
slightly decreasing level of contaminant concentrations (Figures 5 and 6). The observed total
VOC and 1,4-dioxane concentrations in AW-3/AWB-4 well pair (Table 2) also indicate a
slightly decreasing contaminant trend. Continued operation of the SIS Basin Area extraction
-7-

system should further reduce contaminant concentrations in these observation monitoring
wells.
Over the initial year of operation, the extraction system at the SIS Basin Area has removed
328 pounds of volatile organic compounds and 62 pounds of 1,4-dioxane. The following
chart illustrates the mass removal over the 12-month evaluation period:

4.0 QUARTERLY REPORT SUMMARIES
For reference, a summary of the observations from each the four quarterly monitoring events
conducted during the extraction system evaluation process is provided below:
• First Quarterly Report Findings - July 2022 through September 2022:
o The distribution of VOCs and 1,4-dioxane at the Pond 3 Area noted during the first
quarter is centered along the north/northeast trending mafic dike. The effectiveness of
the extraction system is evident from the increased contaminant concentration in R-1,
PW-SF 1, and OW -SF 1.
o The distribution of VOCs and 1,4-dioxane at the SIS Basin Area during the first quarter
had shown an increase in contaminant concentrations when compared to the baseline
sampling primarily due to the operation of RW-SIS7.
• Second Quarterly Report Findings - October 2022 through December 2022:
o The observed VOC and 1,4-dioxane analytical results during the second quarter indicated
an overall reduction in contaminant concentrations as compared to the first quarterly
monitoring event. This reduction is likely a result of dewatering of the bedrock aquifer
and interception of recharge from the contaminant source by the extraction system.
o The observed VOC and 1,4-dioxane analytical results during the second quarter at the
SIS Basin also indicates an overall reduction in contaminant concentrations as compared
to the first quarterly monitoring event. This reduction is likely a result of dewatering of
the SIS Basin area as noted from a lowering of the static surface water level at the outlet
of the SIS Pipe.
• Third Quarterly Report Findings - January 2023 through March 2023:
o The observed total volatile organic compound analytical results during the third quarter
indicated an overall reduction in contaminant concentrations as compared to the second
quarterly monitoring event. The 1,4-dioxane concentrations observed during the third
quarter indicated a slight decreasing trend in the two extraction wells (PW-SF 1 and R-1)
with an increasing trend in adjacent observation wells MW-7B and OW-SF1.
ME

o The total VOC and 1,4-dioxane analytical results at the SIS Basin area during the third
quarter suggests a stable to slightly decreasing level of contaminant concentrations. The
observed total VOC and 1,4-dioxane concentrations in AW-3/AWB-4 well pair, near the
outlet to the SIS Basin, indicated a slightly decreasing contaminant trend.
• Fourth Quarterly Report — April 2023 through June 2023:
o The observed total volatile organic compound concentrations during the fourth quarter
indicated a gradual decreasing contaminant trend over the four quarterly monitoring
events. The 1,4-dioxane concentrations during the fourth quarter indicated a stable and
slightly decreasing contaminant trend.
o The total VOC and 1,4-dioxane analytical data trends during the fourth quarter at the SIS
Basin Area show a stable to slightly decreasing level of contaminant concentrations. The
observed total VOC and 1,4-dioxane concentrations in AW-3/AWB-4 well pair, located
near the outlet of the SIS Basin, also indicate a slightly decreasing contaminant trend.

5.0 CONCLUSIONS AND RECOMMENDATIONS
The objective of TM -II was to evaluate modifications to the existing groundwater extraction
treatment system to improve the removal of contaminant mass from groundwater and further
protect the surface water quality of the SIS and Randleman Lake as described in the RASA. The
initial year of operation of the expanded extraction system has shown progress to that objective
as noted below:
• The operation of the expanded groundwater extraction system outlined in TM-11 has resulted
in the removal and treatment of 5,658 pounds of VOCs and 1,4-dioxane over the initial year
of operation.
• The extraction system at the Pond 3 Area is controlling groundwater flow in the shallow and
deeper bedrock zones as well as the mafic dike structure which serves as a primary
contaminant migration pathway.
• Long-term operation of the Pond 3 extraction system is expected to continue to improve the
groundwater and surface water quality of the SIS drainage basin.
• The expanded extraction system at the SIS Basin Area is creating a capture zone which
controls groundwater flow in the saprolite and shallow bedrock zone.
• The expanded groundwater capture zone at the SIS Basin has resulted in a reduction in
contaminant concentrations in downgradient groundwater monitoring well pair AW-3/AWB-
4.
• The expanded groundwater capture zone at the SIS Basin also appears to limit groundwater
discharge and improve surface water quality at the SW-4 monitoring location.
Continued operation of the expanded extraction system as outlined in TM-11 is recommended to
further reduce contaminant concentrations in groundwater at the Pond 3 and SIS Basin Areas.
To provide for continued monitoring of the effectiveness of the expanded extraction system, the
following quarterly monitoring program is recommended:
-11-

• On a quarterly basis, collect surface water samples from the two on -site drainage features.
The recommended sampling includes: SW-1, SW-2, SW-3, SW-4, and SW-5. This
recommendation was also included in the First Five Year Review Report. The samples
should be analyzed for VOCs by EPA Method 8260D and 1,4-dioxane by EPA Method
8260D SIM.
• Also on a quarterly basis, collect groundwater samples from monitoring wells AW-3 and
AWB-4. These samples will be collected using low -flow methodology and analyzed for
VOCs by EPA Method 8260D and 1,4-dioxane by EPA Method 8260D SIM.
• Groundwater elevations from the Pond 3 and SIS Basin Areas will be collected during the
quarterly sampling events to verify continuity of the capture zones.
This recommended quarterly monitoring program will be implemented beginning with the 2023
fourth quarterly monitoring (December 2023). The results of these monitoring activities will be
reported with the routine Quarterly Progress Reports.

Receipt
The samples were received on 7/7/2023 9:30 AM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperature of the cooler at receipt time was 2.0°C
GC/MS VOA
Method 8260D: The CCV for analytical batch 752-3646 recovered outside control limits for the following
analyte(s):1,2-Dibromo-3-Chloropropane, 2-Chloroethyl vinyl ether, Dichlorodifluoromethane, Chloromethane and 1,2,3-Trichlorobenzene.
These compounds have been identified as a poor performing analytes when analyzed using this method; therefore,
re-extraction/re-analysis was not performed. These results have been reported and qualified.
Method 8260D: The continuing calibration verification (CCV) associated with batch 752-3646 recovered outside acceptance criteria, low
biased, for Vinyl chloride, tert-Butylbenzene and Hexachlorobutadiene. A reporting limit (RL) standard was analyzed, and the target
analytes are detected. Since the associated samples were non -detect for the analyte(s), the data are reported.
Method 8260D: The continuing calibration verification (CCV) associated with batch 752-3646 recovered outside acceptance criteria, low
biased, for Vinyl chloride. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Non -detections of the
affected analytes are reported. Any detections are considered estimated.
Method 8260D: The following samples were diluted to bring the concentration of target analytes within the calibration range: AW-3
(752-9097-2), AW-4 (752-9097-3), AWB-4 (752-9097-4), MW-713 (752-9097-5), OW-SF1 (752-9097-6), OW-SIS1 (752-9097-7), PW-3D
(752-9097-8), PW-SIS7 (752-9097-9), PW-SIS8 (752-9097-10), PW-SF1 (752-9097-11), R-1 (752-9097-12) and RW-SIS1 (752-9097-13).
Elevated reporting limits (RLs) are provided.
Method 8260D_SIM_14DX: Surrogate recovery is within acceptable recovery limits (70-130%) : (CCVIS 680-787871/3).
Method 8260D_SIM_14DX: The matrix spike and matrix spike duplicate (MS/MSD) recoveries for analytical batch 680-787871 were outside
control limits and above calibration. Sample matrix interference is not apparent but the associated laboratory control sample and duplicate
(LCS/LCSD) recovery is within acceptance limits; therefore, the data have been reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
