Re: Remedial Action Progress Report, 2024 Second Quarter
Former Seaboard Chemical and Riverdale Drive Landfill Site
Jamestown, Guilford County, North Carolina
Dear Mr. Caulk:
The Seaboard Group II and the City of High Point are providing this 2024 Second Quarter
Remedial Action Progress Report for the former Seaboard Chemical Corporation facility and the
closed Riverdale Drive Landfill located in Jamestown, Guilford County, North Carolina.
During the second quarter of 2024, the mechanical and phytoremediation treatment systems
processed 3,323,317 gallons of extracted groundwater and leachate. Based on the average
influent contaminant concentrations, approximately 503 pounds of volatile organic compounds
and 32 pounds of 1,4-dioxane were recovered from the groundwater extraction wells and
leachate collection systems.
The system was operational for the entire second quarter of 2024 with the exception of the
following events which exceeded one day in duration:
Date
Duration
Cause of Shutdown
Corrective Measure Taken
4/7/24
1.3 days
Automatic shutdown, high water
levels in T-121 and air stripper
Pump down water levels and re -
start system, adjusted PIDs
4/22/24
10.5 days
Manual shutdown due to clogged
sludge line at clarifier
Pump down clarifier, unclog and
clean sludge line
5/16/24
1.1 days
Automatic shutdown, power failure
Restarted system
5/19/24
1.1 days
Automatic shutdown, power failure
Restarted system
5/24/24
4.5 days
Automatic shutdown, variable
frequency drive (VFD) failure
Replaced VFD and performed
s stem tests
6/15/24
2.0 days
Manual shutdown, lime line clog at
storage tank
Emptied tank, cleared clog and
restarted
There were no other significant shutdowns during this reporting period. Additional cleaning
efforts of the sludge removal system (clarifier and sludge lines) and lime slurry components have
been added to the preventative maintenance program.

As recommended in the October 2023 Technical Memorandum 11 Final Summary Report, a
quarterly groundwater and surface water monitoring program has been implemented. This
monitoring program includes the on -site surface water monitoring locations (SW-1, SW-2, SW-
3, SW-4, and SW-5) and two groundwater monitoring wells at the SIS Basin Area (AW-3/AWB-
4). These sampling locations are shown on Figure 1 of this report.
The 2024 second quarterly groundwater and surface water samples were collected on June 20,
2024. A summary of the laboratory analytical results are provided on Table 1 (groundwater) and
Table 2 (surface water) which is included with this report. These tables also provide the
applicable NC Groundwater Standards, NC Surface Water Standards, NC In -Stream Target
Values, or EPA National Recommended Water Quality Criteria Standards. The Eurofins
laboratory report is included as an attachment to this report.
In addition to the laboratory data summary tables, groundwater potentiometric maps for the Pond
3 area at the former Seaboard Chemical property and the SIS Basin area on the landfill property
are provided on Figure 2 of this report. The results of the quarterly monitoring remain consistent
with prior sampling events.
Please contact Craig Coslett (610/435-1151) or Gary Babb (919/605-4719) if there are any
questions or comments regarding this update.

Receipt
The samples were received on 6/21/2024 9:15 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 3.8°C.
GC/MS VOA
Method 8260D: The following samples were diluted to bring the concentration of target analytes within the calibration range: AW-3
(752-21121-1) and AWB-4 (752-21121-2). Elevated reporting limits (RLs) are provided.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
