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
October 2021 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,
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
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report
October 2021 Page 2

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 Site is located in the central Piedmont Physiographic Province in the northern
portion of the Carolina Slate Belt. Granite is the predominant rock type in the area and
outcrops are observed along the creeks and within the Site. The geology of the Site
consists of fractured granitic gneiss which has been intruded by mafic dikes. The mafic
dikes are generally oriented N20°E and are sub -vertical, dipping to both the northwest
and the southeast. The mafic dikes generally do not occur as single massive tabular
bodies but normally occur as a swarm of thinner tabular and/or irregular dikes within
larger fracture zones within the granitic gneiss. The thickness of individual mafic dikes
ranges from less than one foot to more than 30 feet. Smaller mafic dikes that are not
associated with fracture zones are disseminated throughout the granitic gneiss.
Several prominent geologic structures have been identified and mapped at the Site,
including these significant geologic features:
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report
October 2021 Page 3

Southern Intermittent Stream Fault — N80°E oriented fracture zone/fault that parallels the
Southern Intermittent Stream. Based on an on -site outcrop measurement and fracture
orientation data from the PW-31) core, the fracture zone is believed to dip 43' to the
south;
Seaboard Dike — N20°E oriented mafic dike that extends from the Seaboard Facility to
the vicinity of monitoring well PW-13I and north of the Deep River;
PW-5D Dike/Fault — N200E oriented diabase dike/fault that extends northward from the
east side of the Seaboard Facility near PW-8S to the vicinity of monitoring well PW-5D
north of the Deep River. The PW-51) Fault has an inferred connection with the Southern
Intermittent Stream Fault beneath the Landfill;
Regional Fault/Dike — major regional fault/mafic dike that extends N20°E near PW-6I/6D
and extends north of the Deep River; and
Deep River Fault — southward -dipping fault that forms the east -west segment of the Deep
River. Based on an on -site outcrop measurement and fracture orientation data from the
PW-5D core, the fracture zone is believed to dip 50' to the south.
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
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report
October 2021 Page 4

(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
the topographic highs). 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.
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report

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 the attached Figure 2. 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 impacts from groundwater discharge.
The 2021 annual groundwater and surface water monitoring activities were conducted at the Site
during the period of October 21-28, 2021. Groundwater level gauging was conducted at the
monitoring wells to be sampled to evaluate groundwater flow patterns at the Site (Figure 2).
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 and SW-2 were dry during this sampling event.
2.1 Groundwater Monitoring Network
The existing groundwater monitoring network consists of 25 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. The 25 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 2021 annual groundwater and surface water
monitoring activities were conducted at the Site during the period of October 21-28, 2021.
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 2).
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
October 2021 Page 8

The samples were collected directly in the laboratory -supplied containers which had been
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
October 2021 Page 9

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
October 2021 Page 10

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
October 2021 Page 11

5.0 Hydrogeological Conditions
The depth to groundwater was measured in the 25 compliance monitoring wells during the
October 2021 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 2. This potentiometric map primarily represents
groundwater flow in the uppermost aquifer. The groundwater depths and elevation data for the
Site 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 2021 monitoring
event, was 0.010 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 9 — 14 gallons per minute from PW-DR1 during operation of the system has
demonstrated a drawdown of approximately 24 feet 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 2021 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
October 2021 Page 12

6.0 Laboratory Analytical Results
The complete analytical results for the samples collected during the period of October 21-28,
2021 were received from the laboratory on November 8 and November 22, 2021. 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
2021 monitoring event are shown in a series of figures. Groundwater quality maps
representing the bedrock aquifer are provided for 1,2-dichloroethane (Figure 3), vinyl
chloride (Figure 4), chlorobenzene (Figure 5), 1,4-dioxane (Figure 6), and total VOCs
(Figure 7). The historical groundwater analytical results for specific VOCs, including the
2020 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 7, 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
October 2021 Page 13

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).
Please note that a sample was not collected from monitoring well PW-18 during this
monitoring event. Monitoring well PW-18 is located on the Crutchfield property on the
north side of Randleman Lake from the Site. After numerous attempts to contact the
property owner (written and verbal), permission to access the PW-18 location was not
granted.
Overall, the October 2021 groundwater analytical results and the general distribution of
VOCs in the Site's groundwater are consistent with the historical groundwater quality
monitoring results. 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.
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 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
October 2021 Page 14

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 VOCs or 1,4-dioxane concentrations
above the laboratory practical quantitation limits in any of Randleman Lake
surface water samples. The locations of the surface water monitoring stations are
shown on Figure 2 and a summary of the Randleman Lake surface water
analytical results are provided in Table 3.
Based on field observations during the October 2021 monitoring activities, the
Randleman Lake was at or near the normal pool elevation of 682 feet msl.
Southern Intermittent Stream
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.
Seaboard Chemical/Riverdale Drive Landfill Water Quality Monitoring Report
October 2021 Page 15

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 2.2 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 4.6
ug/l and 1,500 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 — 2.6 ug/1) was reported in surface water sample SW-3 at
a concentration well below the regulatory standard of 330 ug/l. In addition to the
reported concentration of 1,4-dioxane in the sample collected from surface water
monitoring station SW-4, numerous Site VOCs were also reported above the
regulatory standards in this sample. A summary of the analytical data for the
Southern Intermittent Stream samples is provided in Table 3.
Northern Intermittent Stream
The Northern Intermittent Stream surface water sampling stations include:
• 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. Both surface water monitoring stations for the Northern
Intermittent Stream were dry during the October 2021 monitoring event.

October 2021 Page 16

A summary of the laboratory analytical results for October 2020 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 2021 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 2). 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 10 - 15 gallons per minute.
An operational extraction rate of 9 — 14 gallons per minute from PW-DR1 during
this monitoring period has demonstrated a drawdown of approximately 24 feet
which creates an effective capture zone.
Based on the October 2021 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
groundwater 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 2021 monitoring event, concentrations of 1,4-dioxane above
the laboratory practical quantitation limit was reported at three of the nine surface
water monitoring locations. The three surface water samples collected from the
Southern Intermittent Stream exceeded the laboratory quantitation limit and the
established regulatory standard.

• The October 2021 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 2021 groundwater levels at wells located on the
western portion of the Site are approximately 4 feet higher compared to pre -lake
water level conditions.
• Overall, the October 2021 groundwater monitoring results are generally consistent
with historical monitoring data. The geometry and migration of VOC-affected
groundwater at the Site have not been substantially altered by the filling of
Randleman Lake to normal pool. Pumping of extraction well PW-DR1 at a rate
of 9 - 14 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.

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.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.

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.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QS-03 Surrogate recovery outside acceptance limits
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.
