Comment: Well PW-SF1 is referenced in the Section but is not shown on Figure 2.
Response: This well was inadvertently omitted as it has been converted to an
extraction well. The location of PW-SF1 has been included on the revised Figure 2
(attached).

Comment: The third paragraph references an extraction rate/capture zone test that
was completed using well PW-DR01. This well is not shown on any of the figures.
Response: Well PW-DR1 is the primary extraction point located adjacent to Lift
Station 1. The location of this well has been added to Figure 2 of the revised report
(attached).
Comment: Seaboard Group II and the City of High Point should continue to monitor
the contaminant concentrations in wells across the Deep River along with well MW-
12b, in the northwest part of the plume. At well MW-12b, the contaminant
concentrations have not decreased as much over the last five years.
Response: Agreed.
Comment: Well MW-17 (WSW-1) is listed in the table but not shown on any of the
figures. Where is it located?
Response: Well MW-17 is a former drinking water supply well for the landfill
operations. This well was converted into a monitoring well during the RI/FS process
but is not part of the Site's monitoring program. It is located between Lift Station 2
and the Soil Residue Mound.
A revised 2022 Water Quality Monitoring Report which addresses the issues discussed in
this correspondence is attached. If there are any other questions or comments please

1.0 Introduction
1.1 Site Information
The former Seaboard Chemical/Riverdale Drive Landfill Site (the Site) is located
approximately five miles east-southeast of High Point, NC near the intersection of
Riverdale Drive and Interstate 85 (Figure 1). The Site consists of two properties, the
facility where the former Seaboard Chemical Corporation (Seaboard) conducted
operations and the closed municipal Riverdale Drive Landfill (Landfill), as shown on
Figure 2.
The former Seaboard Facility is located at 5899 Riverdale Drive, Jamestown, NC and
consists of approximately 13 acres. Between 1974 and 1989, Seaboard operated solvent
recovery and fuel blending processes at the facility. The corporation declared bankruptcy
in 1989 and was not able to fund the cost of performing the necessary site closure and
remediation. Removal activities were conducted during 1990 and 1992 to remove all
remaining waste materials and certain tanks and equipment from the former Seaboard
Facility. The removal was conducted by Seaboard Group I which was formed by parties
that may have used the services of Seaboard in the past.
The adjacent Landfill, a closed unlined municipal solid waste facility, consists of
approximately 150 acres and bounds the former Seaboard Facility on two sides. The
Landfill was operated from the 1950's until October 1993. The Landfill was permitted
by the North Carolina DEQ - Solid Waste Section in 1979. During Landfill operations,
sections of the two tributary streams that cross the landfill property were piped and solid
waste was used to fill the drainage valleys. The two streams are referred to as the
Southern Intermittent Stream and the Northern Intermittent Stream. During filling of the
Southern Intermittent Stream valley, a leachate collection system was installed adjacent
to the stream channel to collect leachate migrating from the overlying solid waste. In
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 1

1989, a leachate collection system was added to control surface seeps (leachate leaks)
along the slopes of the Landfill.
From approximately 1966 to 1970, Landfill operations also included the disposal and
open burning of spent solvents in shallow pits located just north of the former Landfill
scale house (Figure 2). Periodically, these burn pits were cleaned of residue that
accumulated in a mound to the south of the burn pits. Presently, this mound consists of
approximately 600 cubic yards of contaminated residue capped by a synthetic liner and is
referred to as the "soil residue mound". The Landfill is now capped and maintained
under an approved post -closure plan.
Seaboard Group II was formed in 1994 and entered into an agreement with the City of
High Point (the City) to jointly perform a remedial investigation and prepare a baseline
risk assessment and feasibility study for the Site, including both the former Seaboard
Facility and closed Landfill properties. The Seaboard Group II and the City then entered
into an Administrative Order on Consent (AOC) dated January 30, 1996 with NC DEQ to
perform the remedial investigation. The feasibility study was conducted under a separate
AOC dated July 22, 1997.
Remedial investigations conducted at the Site have documented the presence of
chlorinated and non -chlorinated volatile organic compounds (VOCs) in soils, leachate,
groundwater, and surface water. The results from the remedial investigation indicate that
the VOC-affected groundwater had migrated toward Randleman Lake, which adjoins the
Site along the northern and eastern property boundary of the Landfill. The Randleman
Lake was created by the impoundment of the Deep River in 2006 by the Randleman Lake
Dam, which is located approximately 11.5 miles downstream of the Site.
The Remedial Recommendation Document (February 2005) presented a remedial strategy
for the impacted media at the Site based on the results of the remedial investigation,
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 2

baseline risk assessment, and feasibility study. The remedial design consisted of
groundwater extraction and treatment in combination with institutional controls including
site access control, recorded land use restrictions, and restriction of water supply well
construction. The groundwater and surface water monitoring program is designed to
evaluate the effectiveness of the remedy. The Remedial Recommendation Document was
conditionally approved by the NC DEQ in September 2005.
Seaboard Group II and the City entered into a Remedial Action Settlement Agreement
(RASA) with NC DEQ on December 29, 2008. The RASA provides for the design and
implementation of the approved remedial action program for the Site as well as
completion and reporting of annual groundwater and surface water monitoring activities.
1.2 Site Geology
The geology at the Site was fully evaluated during the Remedial Investigation /Feasibility
Study which was completed in October 2000. The full text and figures of this evaluation
can be reviewed at the following NCDEQ Laserfiche locations:

1.3 Site Hydrogeology
The Site hydrogeology is characteristic of the regional piedmont aquifer system and
consists of three aquifer units: the saprolite and partially weathered rock (PWR) aquifer,
shallow bedrock aquifer, and deep bedrock aquifer. The saprolite/PWR aquifer is the
uppermost aquifer across much of the Site, but is locally absent where the water table
occurs below the top of bedrock. The thickness of the saprolite/PWR aquifer, where
present, is generally less than 20 feet but extends to depths of 90 feet in limited areas
(PW-13I). The shallow bedrock aquifer extends from the top of competent bedrock to a
depth where groundwater flow becomes limited due to the lack of open fractures. The
base of the shallow bedrock zone at the Site is variable but generally believed to occur at
depths of 200 to 400 feet. The deep bedrock aquifer extends downward from the base of
the shallow bedrock aquifer and is characterized by low permeability and limited
groundwater flow. The primary zone of groundwater movement at the Site is considered
to occur within the saprolite/PWR and shallow bedrock aquifer zones.
The saprolite/PWR and shallow bedrock aquifers are hydraulically connected. The
potentiometric surface of shallow groundwater in the saprolite/PWR aquifer is generally
a subdued replica of the original topography of the Site. The saprolite/PWR aquifer is
locally absent where the water table occurs below the top of bedrock (generally beneath
higher topographic elevations). Groundwater flow within the shallow bedrock aquifer is
primarily through fractures in the bedrock and is strongly controlled by subsurface
geologic structures such as faults, fracture zones, and mafic dikes.
Two constant rate discharge tests were conducted in August and September 1997. The
calculated bulk hydraulic conductivity values at the Site range from 0.5 to 3 feet/day in
the saprolite/PWR aquifer and 0.1 to 0.6 feet/day in the shallow bedrock aquifer.

2.0 Water Quality Monitoring Program
The water quality monitoring network at the Site is evaluated on an annual basis. The locations
of the groundwater and surface water samples collected during the annual monitoring event are
shown on Figure 2 and 3, respectively. The primary objectives of the annual groundwater and
surface water monitoring program are:
• Monitor VOC concentrations and migration of the VOC-affected groundwater;
• Monitor groundwater elevations, hydraulic gradients and flow directions;
• Monitor surface water quality in Randleman Lake, Northern Intermittent Stream, and
Southern Intermittent Stream to assess water quality.
The 2022 annual groundwater and surface water monitoring activities were conducted at the Site
during the period of October 12-20, 2022. Groundwater level gauging was conducted at the
monitoring wells to be sampled to evaluate groundwater flow patterns at the Site (Figure 4).
Surface water sampling was conducted at nine surface water stations which included; four
stations along Randleman Lake (SW-6, SW-7, SW-DRP-2, and SW-DRP-11), three stations on
the Southern Intermittent Stream (SW-3, SW-4, and SW-5), and two monitoring stations on the
Northern Intermittent Stream (SW-1 and SW-2). Please note that surface water monitoring
stations SW-1 was dry during this sampling event.
2.1 Groundwater Monitoring Network
The existing groundwater monitoring network consists of 24 monitoring wells which
have been selected to evaluate the lateral and vertical extent of the contaminant plume as
well as the effectiveness of the groundwater extraction system (Figure 2). The 24
monitoring wells sampled for subsequent laboratory analysis include:

3.0 Water Quality Sample Collection
Samples of groundwater and surface water were collected in accordance with the approved
Annual Monitoring Plan — 2010 dated March 17, 2010. A brief description of the sample
collection procedure is provided below. The 2022 annual groundwater and surface water
monitoring activities were conducted at the Site during the period of October 12-20, 2022.
3.1 Field Sample Procedures
Prior to groundwater sampling, water levels were obtained from each well using an
electric water level meter capable of measuring the depth to water to the nearest 0.01 feet.
This information was later used to determine the elevation of the water table in each
monitoring well relative to surveyed datum (Table 1). The groundwater elevations are
used to develop a potentiometric map of the shallow water table (Figure 4).
The monitoring wells were sampled using low -flow purge and sample procedures. The
groundwater samples were collected using either a peristaltic pump or Grunfos pump
with disposable poly tubing. The depth of the intake tubing is positioned at the mid -point
of the well screen and the pumping rate is adjusted to match recharge and minimize
drawdown in the well. Multiple field parameters, including pH, specific conductivity,
temperature, dissolved oxygen, and ORP, are constantly monitored using a flow cell.
The turbidity of the influent groundwater is periodically evaluated using a field meter
capable of measuring turbidity to +0.01 NTU. Low -flow purging of the well continues
until the field parameters have stabilized and the NTU concentration is <10 NTUs, at
which time the sample is collected. The samples are collected in the following order:
• VOCs and 1,4-dioxane
• Field parameters (pH, conductivity, temperature, dissolved oxygen)
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 7

The samples were collected directly in the laboratory -supplied containers which were
pre -filled with the appropriate preservative. No filtering of the samples was performed
either in the field or laboratory. After collection, the samples were placed in a cooler on
ice for overnight shipment to the analytical laboratory.
Surface water samples were collected directly into the laboratory -supplied containers as
grab samples. Sampling personnel wore new disposable nitrile gloves for each surface
water sample collected. The surface water samples collected from the four stations along
the Randleman Lake were collected at two discrete intervals: a shallow sample collected
one foot below the surface, and a deeper sample collected one foot above the bottom of
the Lake. The Randleman Lake water samples were collected using a stainless steel
discrete -interval Kemmerer water sampler. The actual depths of the shallow and deeper
Randleman Lake surface water samples are provided in Table 4. As with the
groundwater samples, these samples were stored in a cooler on ice prior to overnight
delivery to the analytical laboratory.
3.2 Field Quality Assurance
Two trip blank samples were prepared by the analytical laboratory and accompanied the
sample shipments until receipt by the laboratory. The trip blank samples were analyzed
for VOCs. Temperature blanks were also provided with the sample shipments to assure
the proper temperature was maintained until delivery to the analytical laboratory.
3.3 Sample Delivery/Chain of Custody
All groundwater and surface water samples were stored in coolers on ice immediately
after collection. Individual sample containers for each monitoring well or surface water
sample were placed in zip lock plastic bags to reduce the potential for cross
contamination between sample locations. Chain -of -Custody control documents were
prepared and shipped with each cooler. Custody seals were also used for each cooler to
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 8

maintain sample integrity until delivery to the analytical laboratory. The sample coolers
were shipped via Federal Express for next morning delivery to the analytical laboratory.
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 9

4.0 Laboratory Analysis
The groundwater and surface water samples were analyzed for VOCs by EPA Method 8260D
and 1,4-dioxane by EPA Method 8260D SIM. The laboratory performing the water quality
analysis is Environmental Conservation Laboratories, Inc. (ENCO) of Cary, North Carolina,
which is a NC Certified Laboratory. Internal quality control samples, including matrix
spikes/matrix spike duplicates, were performed by ENCO for each set of samples. The ENCO
laboratory reports, including internal quality control samples, are provided with this report in
Appendix A.
Field parameters (pH, specific conductivity, temperature, dissolved oxygen) were also measured
by the sampling personnel for each groundwater and surface water sample using calibrated
meters.
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 10

5.0 Hydrogeological Conditions
The depth to groundwater was measured in the 24 compliance monitoring wells during the
October 2022 monitoring event. The groundwater elevations were calculated relative to the
surveyed measuring point (top of casing) for each monitoring well. A groundwater
potentiometric map is provided as Figure 4. This potentiometric map primarily represents
groundwater flow in the uppermost aquifer. The groundwater depths and elevation data for the
Site monitoring wells are summarized in Table 1.
In the bedrock aquifer the general groundwater flow direction across the Site is northeastward
toward Randleman Lake. The vertical hydraulic gradient in the shallow bedrock aquifer, as
measured between monitoring wells MW-3C and OW-DR2 during the October 2022 monitoring
event, was 0.021 feet/feet downward.
An Extraction Rate/Capture Zone Test was conducted by ERM NC, PC in August 2002. This
test used well PW-DR1 as the primary extraction point to determine the potential capture zone
using various pumping rates. The results of this test indicated pumping at a relatively low rate of
10 - 20 gallons per minute from PW-DR1 effectively contains the contaminant plume. A
pumping rate of 7 gallons per minute from PW-DR1 during operation of the system has
demonstrated a drawdown of approximately 45 below top of casting which creates an effective
capture zone.
The filling of Randleman Lake began in 2006 and the lake level reached normal pool elevation
(682 feet msl) in 2008. Consistent with prior gauging events, and confirmed with the data
collected during the October 2022 monitoring event, groundwater levels at monitoring wells
located adjacent to the lake have risen 10 - 12 feet as compared to pre -lake water level
conditions. Inland from the lake, groundwater levels at wells located on the western portion of
the Site have risen approximately 4 feet due to the lake impoundment.
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 11

6.0 Laboratory Analytical Results
The complete analytical results for the samples collected during the period of October 12-20,
2022 were received from the laboratory on October 28 and 31, 2022, and November 1 and 7,
2022. A summary of the analytical results are provided for groundwater (Table 2), surface water
(Table 3), and field parameters (Table 4).
6.1 Groundwater Analytical Results
The analytical results for selected groundwater contaminants collected during the October
2022 monitoring event are shown in a series of figures. Groundwater quality maps
representing the bedrock aquifer are provided for 1,4-dioxane (Figure 5), total VOCs
(Figure 6), 1,2-dichloroethane (Figure 7), chlorobenzene (Figure 8), and vinyl chloride
(Figure 9). The historical groundwater analytical results for specific VOCs, including the
2022 data, are summarized in Table 2 and the ENCO laboratory reports are provided in
Appendix A. Measurements of pH, temperature, and specific conductance as determined
in the field during sample collection are provided in Table 4. Additional monitoring well
information including the latitude/longitude of each well location is provided in Table 5.
The main mass of VOC-impacted groundwater generally extends northeastward across
the Site to the Randleman Lake basin. As shown on Figure 6, the highest levels of VOCs
are present in the vicinity of the northeast corner of the Seaboard Facility near the
location of three former surface impoundments. Prior to their closure and capping
between 1984 and 1986, the area of the former impoundments served as a primary source
area of VOC releases to the groundwater at the Seaboard Facility. Additionally, elevated
VOC concentrations in groundwater are also present in the area of the soil residue
mound, a contaminant source area located at the Landfill which has also been closed and
capped with a synthetic liner.
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 12

During this monitoring event, VOCs were detected in a limited area across Randleman
Lake to the northeast of the Site. Minor concentrations of VOCs at levels above the
North Carolina 2L Groundwater Quality Standards were detected at off -site bedrock
monitoring wells PW-15D and PW-16D. These bedrock monitoring wells are located on
the north side of the Randleman Lake basin from the Site. The extent of the VOC
contaminant plume on the north side of Randleman Lake appears to be limited primarily
to property encompassed by the Lake's buffer zone, which is maintained and regulated by
the Piedmont Triad Regional Water Authority (PTRWA).
Overall, the October 2022 groundwater analytical results and the general distribution of
VOCs in the Site's groundwater are consistent with the historical groundwater quality
monitoring results. As shown on Figure 10, a historical reduction in contaminant
concentrations in the monitoring wells on the north side of Randleman Lake is evident
from the groundwater VOC and 1,4-dioxane data collected during this monitoring event.
6.2 Surface Water Analytical Results
Surface water sampling was conducted at the Southern Intermittent Stream, Northern
Intermittent Stream, and at various locations and depths in Randleman Lake. The
surface water monitoring results for VOCs and 1,4-dioxane are summarized in Table 3
and the ENCO laboratory report is provided in Appendix A.
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 13

Randleman Lake
The Randleman Lake surface water sampling stations include:
• SW-6 — Upstream and background sample location for the Site,
• SW-DRP-2 — Adjacent to the Site near Lift Station 1 and PW-DR1,
• SW-7 — Downstream of the Site at the I-85 bridge, and
• SW-DRP-11 —Downstream (-1 mile) at Richland Creek confluence.
The laboratory analytical data indicated no VOC concentrations above the
laboratory practical quantitation limits in any of Randleman Lake surface water
samples. Only one Randleman Lake sample reported a concentration of 1,4-
dioxane above the laboratory reporting limit. The surface sample (1' depth)
collected at surface water sample location SW-DRP11 reported a concentration of
1.0 ug/l. No other Randleman Lake surface water samples reported detectable
concentrations of 1,4-dioxane above the laboratory reporting limit. The locations
of the surface water monitoring stations are shown on Figure 3 and a summary of
the Randleman Lake surface water analytical results are provided in Table 3.
Note that the SW-DRP11 surface water monitoring station is located
approximately 4,000 feet downstream of the Site at the confluence with Richland
Creek. There are at least two known sources of 1,4-dioxane surface water
contamination on Richland Creek upgradient of this confluence.
Based on field observations during the October 2022 monitoring activities, the
Randleman Lake was at or near the normal pool elevation of 682 feet msl.

The Southern Intermittent Stream surface water sampling stations include:
• SW-5 — Upstream of Seaboard Facility and downstream of City MRF,
• SW-3 — Downstream of Seaboard Facility and upstream of Landfill, and
• SW- 4 — Downstream of both Seaboard Facility and Landfill.
The compound 1,4-dioxane was reported in all three of the Southern Intermittent
Stream surface water monitoring stations. The upstream surface water monitoring
station (SW-5) reported a 1,4-dioxane concentration of 1.6 ug/l. Both of the
downstream surface water monitoring stations on the Southern Intermittent
Stream, SW-3 and SW-4, reported detectable 1,4-dioxane concentrations of 2.1
ug/I and 14 ug/l, respectively.
No other Site VOCs were reported above the laboratory reporting limits in the
samples collected from surface water monitoring station SW-5. Only one VOC
(cis-1,2-dichloroethene — 1.2 ug/1) was reported in surface water sample SW-3 at
a concentration well below the regulatory standard of 60 ug/l. The sample
collected from surface water monitoring station SW-4 reported seven VOCs
above the laboratory reporting limit, with two compounds (1,2-dichloroethane
and vinyl chloride) exceeding the regulatory standards. A summary of the
analytical data for the Southern Intermittent Stream surface water samples is
provided in Table 3.
Northern Intermittent Stream
The Northern Intermittent Stream surface water sampling stations include:
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 15

• SW-1 Surface Water Station —Upstream of the Landfill, and
• SW-2 Surface Water Station — Downstream of the Landfill.
The flow path of the Northern Intermittent Stream was re-routed in 2011 and no
longer passes through a pipe beneath the Landfill. Due to a limited watershed
area, these two surface water monitoring stations are typically dry except during
periods of heavy rainfall. The upstream surface water location (SW-1) was dry
during the October 2022 monitoring event. A surface water sample was collected
from the SW-2 location which reported a 1,4-dioxane concentration of 14 ug/l.
No VOC compounds were reported in this sample above the laboratory reporting
limits.
A summary of the laboratory analytical results for October 2022 surface water
monitoring event is provided on Table 3. A copy of the ENCO laboratory
analytical report for the surface water samples is provided with Appendix A.
6.3 Quality Control Samples
Two trip blanks were submitted and analyzed for quality assurance purposes. No VOCs
were detected at a concentration equaling or exceeding its laboratory quantitation limit in
either of the trip blanks.

7.0 Conclusions
The major findings of the annual groundwater and surface water monitoring activities for
October 2022 monitoring event at the Site include the following:
• The overall groundwater flow pattern at the Site continues to be toward
Randleman Lake on both sides of the Lake basin (Figure 4). Operation of the
extraction well PW-DR1 over the past year indicates a significant capture zone for
monitoring wells along the northern section of the Landfill adjacent to Randleman
Lake. The observed capture zone also extends to the bedrock wells on the north
side of Randleman Lake. The capture zone can be maintained by pumping
extraction well PW-DR1 at a rate of approximately 7 - 10 gallons per minute. An
operational extraction rate of 7 gallons per minute from PW-DR1 during this
monitoring period has demonstrated a drawdown of approximately 45 feet below
top of casing which creates an effective capture zone.
• In addition to the PW-DR1 extraction well, four additional extraction wells were
added in June 2022 to supplement the existing remedial system. Two new
extraction wells (R-1 and PW-SF1) are located immediately downgradient of the
former Seaboard processing area (Pond 3). Also, two new extraction wells (RW-
SIS7 and RW-SIS8) are located at the SIS Basin area. These extraction wells
have proven to be very effective in removing contaminant mass from the saprolite
and shallow bedrock groundwater zones. A separate report is being prepared to
evaluate the effectiveness of these new extraction locations.
Based on the October 2022 monitoring results and historical data, the main VOC
plume extends from the Site through the Southern Intermittent Stream valley
northeastward to Randleman Lake. The minor concentrations of VOCs detected
on the north side of the Randleman Lake in monitoring wells PW-15D and PW-
16D represents the northern extent of the VOC plume. Based on historical
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report (Revised 3.6.2023)
October 2022 Page 17

analytical results, the northern extent of Site VOCs in the groundwater north of
Randleman Lake is likely restricted to the Piedmont Triad Regional Water
Authority regulated buffer.
• During the October 2022 monitoring event, concentrations of 1,4-dioxane above
the laboratory practical quantitation limit were reported at five of the nine surface
water monitoring locations. The four surface water samples collected from the
Southern and Northern Intermittent Streams exceeded the laboratory quantitation
limit and the established NC In -Stream Target Value of 0.35 ug/l.
Of the four surface water monitoring stations on Randleman Lake, the upstream
sample (SW-8), sidegradient sample (SW-DRP2), and the sample collected
immediately downstream of the Site (SW-7) did not report 1,4-dioxane above the
laboratory method detection limit of 0.30 ug/l. Only one of the Randleman Lake
surface samples (SW-DRP11 — F depth) reported a detectable 1,4-dioxane
concentration. The reported concentration of 1.0 ug/1 in this sample is slightly
above the NC In -Stream Target Value of 0.35 ug/l. Note that the SW-DRP11
surface water monitoring station is located approximately 4,000 feet downstream
of the Site at the confluence with Richland Creek. There are at least two known
sources of 1,4-dioxane surface water contamination on Richland Creek upgradient
of this confluence.
• The October 2022 monitoring data indicated that groundwater levels at
monitoring wells located adjacent to the Randleman Lake have risen
approximately 10 to 12 feet compared to pre -lake water level conditions. Inland
from the lake, the October 2022 groundwater levels at wells located on the
western portion of the Site are approximately four feet higher compared to pre -
lake water level conditions.

October 2022 Page 18

• Overall, the October 2022 groundwater monitoring results are generally consistent
with historical monitoring data. The pumping of extraction well PW-DR1 at a
rate of 7 gallons per minute has demonstrated a significant capture zone created
by the drawdown on both sides of Randleman Lake. A historical reduction in
contaminant concentrations in the monitoring wells on the north side of
Randleman Lake from the Site is evident from the groundwater VOC data
collected during this monitoring event (Figure 10).

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.
A-07 Analyte biased low in LCS but detected in the reporting limit standard. Since the analyte in the associated
sample was not detected, there is no impact on data quality.
3-04 Result may be biased high. Associated calibration verification standard exceeded the upper control limit.
1-05 Result may be biased low. Associated calibration verification standard did not meet the minimum control
limit.
0-01 This compound is a common laboratory contaminant.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.
FINAL This report relates only to the sample as received by the laboratory, and may only be reproduced in full. I Page 109 of 115

Receipt
The samples were received on 10/27/2022 8:00 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 5.4°C
GC/MS VOA
Method 8260D_SIM: The matrix spike duplicate (MSD) recoveries for analytical batch 400-598314 were outside control limits. Sample
matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within
acceptance limits.
Method 8260D_SIM: The following sample(s) was collected in a properly preserved vial; however, the pH was outside the required criteria
when verified by the laboratory. The samples were analyzed outside the 7-day holding time specified for unpreserved samples but within
the 14-day holding time specified for preserved samples: 4101-MW12B (680-224127-4) and 4101-OWLFS2 (680-224127-8).
Method 8260D_SIM: The following sample(s) was collected in a properly preserved vial; however, the pH was outside the required criteria
when verified by the laboratory. The sample was analyzed outside the 7-day holding time specified for unpreserved samples but within
the 14-day holding time specified for preserved samples: 4101-OWLFS2 (680-224127-8).
Method 8260D_SIM: The following samples were diluted to bring the concentration of target analytes within the calibration range:
4101-MW12A(680-224127-3), 4101-MW15A(680-224127-6), 4101-OWDR2 (680-224127-7), 4101-OWLFS2 (680-224127-8), 4101-PW5D
(680-224127-9), 4101-PW41 (680-224127-10) and 4101-PWSF1 (680-224127-12). 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.
