Brownfield Project No. 24007-20-032
ECS Project No. 49:10039-B
1.0 SITE BACKGROUND & PROJECT INFORMATION
The subject brownfields site (Brownfields Project Number 24007-20-032), known as Wright's Executive
Sales II, currently consists of two parcels and a total of 2.371 acres of land (see Figure 1 and 2). It is in a
commercial area of Durham just to the south of W. Geer St. and west of Foster St. The Subject Site was
occupied by three buildings associated with Acme Plumbing and Heating offices and storage, a stand-
alone yoga studio, Motorco Music Hall, and The Mothership, which was a creative space to share, make,
and collaborate on artistic projects. The Subject Site is currently identified by the Durham County Online
GIS Database with the following Parcel Identification Numbers (PINS) and street addresses:
• 620 Foster St. 0822-90-31-8262; 1.91 acres
• 616 Foster St. 0821-99-29-7413; 0.461 acres
The property is currently planned to be redeveloped with a mixed multi -family residential,
commercial/retail, and/or restaurant complex. In order to accomplish redevelopment, it has been
estimated that the brownfields site will require an estimated additional 5,000 cubic yards of imported fill
material that was originally not expected to be necessary.
Correspondence with the North Carolina Department of Environmental Quality (NCDEQ) Brownfields
Redevelopment Section (BRS) on October 14, 2022 indicated that a total of five (5) representative
composite soil characterization samples would be required to be collected from virgin borrow source soil
to support the additional import of an estimated 5,000 cubic yards. This approach differed from the June
7, 2022 Program revised and approved Environmental Management Plan (EMP) required sampling
frequency of one representative composite sample per every approximate 500 cubic yards. This approach
was documented in the Double R Import Soil Sampling Work Plan, Revision 1.0, prepared by ECS and dated
December 8, 2022 which received Brownfields approval on December 12, 2022.
The initially approved Work Plan scope of work was completed on December 16, 2022 with no deviations,
other than noted in Section 2.3 below, from the approved Work Plan.
ECS submitted the Report of Import Soil Sampling Assessment (ECS Project No. 49-10039-13) to NCDEQ BRS on
January 19, 2023 for the sampling activities conducted in December, 2022. Upon review of the report, the
BRS requested that ECS re -sample the stockpiled soil for VOCs by EPA Method 8260 indicated in
correspondence with Ms. Holly Samaha-Smith on January 30 and February 6, 2023. On February 16, 2023,
ECS re -mobilized to Double R Farm in an effort to re -collect VOC samples, however the stockpile that was
previously sampled was apparently no longer present at the site. Upon communication with the site
contractor for the construction site at the Wright's Executive II site, it was decided that the import of 5,000
CY of soil would no longer be needed at the time, and soil was not imported to the site for grading.
On May 19, 2023, correspondence with the site contractor for the Wright's Executive Sales II Brownfields site
re -indicated the need for approximately S00 CY of soil from Double R Farm for site grading activities beginning
in August, 2023. Correspondence with the BRS on May 24, 2023 indicated the need to re -sample the virgin
source area for VOCs by EPA Method 8260 under the previously approved Wright's Executive Sales 11—Double
R Farm Import Soil Sampling Work Plan - Revision 1.0 dated December 16, 2022. ECS understands that the
SVOC, organochlorine pesticide, organophosphorus pesticide, herbicide, RCRA-8 metal, and Cr VI data from
the soil samples collected on December 16, 2022 will be valid for the approval of the proposed import of soil

from Double R Farm. ECS submitted the Double R Farm Import Soil Sampling Work Plan — June 2023
Addendum — Revision 1.0 to NCDEQ BRS on June 19, 2023, which was approved on June 21, 2023.
The approved scope of work outlined in Double R Farm Import Soil Sampling Work Plan — June 2023
Addendum — Revision 1.0 was completed on July 18, 2023.
The data obtained from executing this work plan is intended for regulatory use by the NCDEQ BRS only.
2.0 SCOPE OF SERVICES
The objective of this assessment is to maintain the liability protections offered by the Program by
characterizing soil quality prior to being imported to the site. The borrow source property is an
approximately 38.8-acre property located at 2624 Hamlin Road in Durham, North Carolina and is identified
by PIN 0844-81-37-5147. A November, 2021 aerial map of the borrow source property is illustrated on
Figure 3, and the approximate location of the proposed imported soils stockpiled for the December 2022
sampling event from virgin borrow source material have been illustrated on Figure 4. A May, 2023 aerial
map of the borrow source property with July, 2023 sample locations is included as Figure S.
The borrow source property is currently being utilized as a land clearing and inert debris (LCID) landfill and
is zoned for agricultural use. Double R Farm Landfill reportedly accepts yard waste, brush, trees, topsoil,
dirt, rock, gravel, and concrete, and sells bales of straw, large landscape rocks, fill dirt, and topsoil. A
review of historical aerial photography on Google Earth indicates that the borrow source property may
have been used for agricultural purposes from at least December 1985 through February 1999. By March
2002 the property appears to be undeveloped wooded land, and it maintains this land use through at
least February 2018. Land use prior to 1985 is unknown; however, is likely to have been undeveloped
wooded land and/or used for agricultural purposes. No additional information on prior land use history
was able to be obtained prior to this assessment.
Import soil assessment activities were conducted by ECS and initiated on December 16, 2022. They
consisted of the collection and laboratory analysis of six (6) soil samples. The soil samples consisted of five
(5) representative composite soil samples incorporating discreet volatile organic compound (VOC)
samples from a stockpile created from virgin borrow source material proposed for import to the site, as
well as one (1) duplicate soil sample from the borrow source area.
On July 18, 2023, soil assessment activities were continued by ECS in order to obtain in situ VOC data from
the virgin borrow source area. This included the advancement of five (5) hand auger borings in multiple
locations at the virgin borrow source area, field screening of soils using a photoionization detector (PID),
and submission of one (1) discrete VOC sample, as well as one (1) duplicate for laboratory analysis from
in situ borrow source soil.
A photographic log documenting the field sampling activities is provided in Appendix A.

Wright's Executive Sales
Brownfield Project No. 24007-20-032
ECS Project No. 49:10039-B
2.1.1 December, 2022 Sampling Event
On December 16, 2022, ECS mobilized to the borrow source property to collect five (5) representative
composite soil samples (DRSP-1 through DRSP-5) from the virgin soils currently stockpiled for proposed
import to the site. The stockpile was flagged off in approximate 1,000 cubic yard cells, and subsequently
one 5-point representative composite soil sample was collected from each cell. A duplicate soil sample
was collected from the location of DRSP-2 The approximate location of the stockpile and sample locations,
and grab sample identification labels are illustrated on Figure 4.
Soils collected from the virgin stockpiled soils proposed for import to the site were collected utilizing a
decontaminated stainless steel hand auger. The hand auger was decontaminated upon arrival, between
each representative composite soil sample area, and prior to departure from the site. Decontamination
was conducted with scrub bushes and a municipal water/Alconox mix, followed by a municipal water
rinse.
The soil samples were composited from five (5) separate grab samples at each composite sample location
with a duplicate aliquot for each grab sample. Each duplicate aliquot was field screened using a
PlDcalibrated in the field on the day of assessment per manufacturer's guidelines. ECS personnel observed
the soil from each boring and noted the color and texture of the soil. Additional field indicators such as
soil staining and distinguishable odors were also noted if present during observation. A summary table of
the field screening results from December 2022 is provided in Table 1.
2.1.2 July, 2023 Sampling Event
On July 28, 2023, ECS re -mobilized to the borrow source property to collect one (1) discrete VOC soil
sample (identified as DR-1) from in situ soils anticipated for export. ECS personnel advanced five (5)
borings in select areas of the virgin material borrow source area on the subject property identified as HA -
A through HA-E (as illustrated in Figure 5). The hand auger was decontaminated upon arrival, between
each boring location, and prior to departure from the site. Decontamination was conducted with scrub
bushes and a municipal water/Alconox mix, followed by a municipal water rinse.
ECS personnel collected grab samples at one (1) foot intervals in each boring advanced, which were placed
in 4 oz glass resealable jars and immediately placed on ice upon collection. In addition, ECS collected
duplicate grab sample aliquots at each depth interval which were placed in plastic, resealable bags for
field screening. ECS personnel screened each duplicate aliquot using a PID instrument, which was
calibrated in the field on the day of assessment per manufacturer's guidelines.
A summary table of field screening results from July 2023 is provided in Table 2. Boring logs, describing
subsurface lithologic conditions and field screening results, are provided in Appendix B.
2.2 Soil Sample Collection
2.2.1 December, 2022 Sampling Event
Soil samples were collected by ECS personnel wearing new disposable powder free nitrile gloves
exchanged between the collection of each aliquot. The representative composite samples were comprised
of five individual grab soil samples collected in duplicate re -sealable bags. The duplicate aliquots were
screened using a PID for volatile vapors and then considered to be ineligible for sampling. The individual
grab soil sample with the highest PID reading, from the unopened re -sealable bag was appropriately
3

ECS Project No. 49:10039-B
packaged and submitted to Eurofins, a North Carolina certified laboratory (NC Certification No. 269),
located in Savannah, GA to be analyzed for VOCs using EPA Method 8260. Subsequently, it was then gently
mixed with the other four aliquots and one representative composite soil sample was containerized and
submitted for North Carolina certified laboratory analysis for semi -volatile organic compounds (SVOCs) by
EPA Method 8270, total metals regulated under the Resource Conservation and Recovery Act (RCRA
metals) using EPA Method 6020/7471, hexavalent chromium (Cr VI) by EPA Method 7199, organochlorine
pesticides by EPA Method 8081, organophosphorus pesticides by EPA Method 8141, and herbicides by
EPA Method 8151.
A duplicate soil sample (DUP-1) was collected as a duplicate of DRSP-2. The duplicate was submitted for the
same soil analyses as listed above.
ECS maintained chain of custody (COC) procedures throughout the sample collection and transportation
process. A copy of the analytical laboratory reports along with accompanying COC documentation is included
in Appendix C. Field notes of soil sampling activities are included in Appendix D.
2.2.2 July, 2023 Sampling Event
Soil grab samples were collected by ECS personnel wearing new disposable powder free nitrile gloves. The
grab sample aliquot placed in 4 oz resealable glass jars with the highest corresponding duplicate aliquot PID
screening value was selected for laboratory analysis. The grab sample obtained from boring HA-B (see Figure
5) at the depth interval of 2 to 3 feet below ground surface (ft bgs) indicated the highest PID reading (6.1 parts
per million or ppm) for the grab samples obtained from the 5 borings and was thus selected for laboratory
analysis. The soil in the 4 oz glass container was transferred to appropriate laboratory containers using a
Terracore sampler while wearing new disposable powder free nitrile gloves. The sample containers were
subsequently immediately placed on ice. ECS submitted one (1) discreet sample identified as DR-1, as well as
one (1) duplicate identified as DUP-1 for laboratory analysis of VOCs by EPA Method 8260. The VOC samples
were submitted to Pace Analytical, a North Carolina certified laboratory (NC Certification No. 12), located in
Huntersville, NC. ECS maintained chain COC procedures throughout the sample collection and transportation
process. A copy of the analytical laboratory reports along with accompanying COC documentation is included
in Appendix C.
2.3 Deviation from Approved Work Plan
Soils were collected using a decontaminated stainless steel hand auger and not a shovel, as outlined in the
approved Work Plan.
As outlined in Double R Farm Import Soil Sampling Work Plan — June 2023 Addendum — Revision 1.0, the
anticipated volume of soil needed for import was reduced from 5,000 CY to 500 CY. Therefore, ECS reduced
the number of samples to one (1) sample in accordance with the June 7, 2022 Environmental Management
Plan (EMP) of one representative sample per every approximate 500 CY of proposed imported soil for the
July 2023 sampling event.
Soil from the virgin borrow source area was not able to be stockpiled prior to sampling for the July 2023
sampling event. As such, ECS conducted in situ soil sampling as outlined in Double R Farm Import Soil Sampling
Work Plan —June 2023 Addendum — Revision 1.0, which was approved on June 21, 2023.

3.0 LABORATORY ANALYTICAL RESULTS
3.1 Soil Analytical Results
The soil samples collected at Double R import source area on December 16, 2022 (DRSP-1 through DRSP-
5 and DUP-1) were analyzed for VOCs, SVOCs, pesticides, herbicides, and RCRA metals including Cr VI,
respectively. Laboratory analysis of soil samples DRSP-1 through DRSP-5 and DUP-1, collected on
December 16, 2022, indicated acetone at concentrations above laboratory method detection limits but
below laboratory reporting limits and below applicable Inactive Hazardous Waste Branch (IHSB)
Preliminary Site Remediation Goals (PSRGs). Acetone is a commonly detected laboratory artifact in soil
samples, and it is ECS' opinion that the detection of acetone in the samples DRSP-1 through DRSP-5 and
DUP-1 are not representative of actual soil conditions at the time of sampling on December 16, 2022.
Laboratory analysis of soil samples DRSP-1 through DRSP-5 and DUP-1, collected on December 16, 2022,
reported concentration or estimate concentrations of barium, cadmium, chromium (total), lead,
selenium, and mercury at above their laboratory method detection limits but below their respective
PSRGs. Cr VI was detected in soil DRSP-1, DRSP-2, DRSP-4, and DUP-1 at concentrations or estimated
concentrations above the Residential Health Based PSRG, but below the Protection of Water and
Industrial/Commercial Health Based PSRGs. Cr VI was additionally detected at a concentration above the
Protection of Groundwater PSRG in soil sample DRSP-2. Cr VI was detected above laboratory method
detection limits, but below the Residential Health Based PSRG in DRSP-5. Cr VI was not detected above
the laboratory method detection limit in DRSP-3.
Laboratory analysis of soil samples DRSP-1, DRSP-2, DRSP-4 and DRSP-5, collected on December 16, 2022,
detected arsenic at concentrations above the Residential Health Based PSRG, but below the Protection of
Groundwater PSRG. The soil samples DRSP-3 and DUP-1 detected arsenic at concentrations above the
laboratory reporting limit but below the Residential Health Based PSRG.
Laboratory analysis of the six (6) soil samples submitted collected on December 16, 2022 for analysis did
not detect SVOC, organochlorine pesticide, organophosphorus pesticide, or herbicide constituents above
their respective laboratory method detection limits.
Laboratory analysis of DR-1, which was collected on July 18, 2023, did not indicate VOC constituents at
concentrations above their respective laboratory method detection limits. The laboratory analysis of DUP-
1, collected on July 18, 2023, indicated p-isopropyltoluene at an estimated concentration above its
respective laboratory method detection limit. P-Isopropytoluene is a common, often naturally occurring
VOC that is sometimes found in arboreous plants. It is ECS' opinion that the p-isopropyltoluene detection
in DUP-1 (collected on July 28, 2023) is from a naturally occurring source.
Laboratory analytical results for the proposed import borrow source material are summarized on Table 3.
A copy of the analytical laboratory reports along with accompanying COC documentation is included in
Appendix C.

4.0 QUALITY ASSURANCE/QUALITY CONTROL
In accordance with the Brownfields approved Work Plan, sample duplicates were collected and submitted
for soil to support QA/QC of this assessment. The duplicate, identified as DUP-1, was submitted for the
same media and laboratory analyses as the sample that duplicated (DRSP-2).
Following sample collection on December 16, 2022, the sample containers were labeled and maintained
under COC until delivered to Eurofins in Raleigh, NC by local courier. Following sample collection on July
18, 2023, the sample containers were labeled and maintained under COC until delivered to Pace in
Raleigh, NC by local courier. A COC document was utilized throughout the collection and transportation
of the samples. A level II QA/QC package was reported by the laboratory.
Review of the duplicate sample data presented herein indicates a concentration of Cr VI to be an
approximate order of magnitude higher in the record sample identified as DRSP-2 than in its duplicate
sample identified as DUP-1 (collected on December 16, 2022). A comparison of other analytical results
obtained from the record sample (DRSP-2) and its duplicate (DUP-1) appear to be similar and have not
affected the interpretations of those results. ECS opines that the Cr VI concentration reported in the
record sample is not representative of actual site conditions, as other sample locations collected during
this assessment from the same stockpile comprised of virgin material have been reported with Cr VI
concentrations comparable to DUP-1's result.
5.0 INVESTIGATION DERIVED WASTE
Soil investigative derived waste (IDW) produced in the December 2022 and July 2023 sample events was
placed back down its respective borehole at the same approximate depth it was recovered. Excess soil,
where applicable, was spread at the surface near each respective borehole from which it was derived.
6.0 FINDINGS & CONCLUSIONS
Laboratory analysis of soil samples collected from the proposed import borrow source on December 16,
2022, did not detect VOCs, SVOCs, pesticides, or herbicides above their respective PSRGs.
Laboratory analysis of in situ soil samples collected from the virgin borrow source on July 18, 2023, did
not detect VOCs above their respective PSRGs.
Cr VI was detected in soil samples DRSP-1, DRSP-2, DRSP-4, and DUP-1 at reported or estimated
concentrations above the Residential Health Based PSRG. The reported concentration for DRSP-2 also
exceeded its Protection of Water PSRG. Industrial/Commercial Health Based PSRGs were not exceeded.
Please note that duplicate sample data obtained by QA/QC protocols implemented for this assessment
have reported a concentration of Cr VI to be an approximate order of magnitude higher in the record
sample identified as DRSP-2 than in its duplicate sample identified as DUP-1. A comparison of other
analytical results obtained from the record sample (DRSP-2) and its duplicate (DUP-1) appear to be similar
and have not affected the interpretations of those results. The USEPA Contaminated Site Cleanup
Information (CLU-IN) Chromium VI Overview dated October 26, 2018, indicates that "chromium is
abundant in nature and is generally found as trivalent chromium (Cr III) or Cr VI. Cr VI is most often
0

produced by industrial processes and may be an indicator of environmental contamination. This form
exists in oxidizing conditions and can move down through soil to underlying groundwater. The
concentration of naturally occurring chromium in US soil range from 1 to 2,000 parts per million (ppm)".
As such, ECS opines that the Cr VI concentration reported in the record sample is not representative of
actual site conditions, and representative of naturally occurring or anthropogenic background
concentrations. Other sample locations collected during this assessment from the same stockpile
comprised of virgin material have been reported with Cr VI concentrations comparable to DUP-1's result.
Laboratory analysis of the samples DRSP-1, DRSP-2, DRSP-4 and DRSP-5 detected arsenic at
concentrations above one or more of its respective PSRGs; however, according to Dragun and Chekiri's
Elements in North American Soils, Second Edition, naturally occurring concentrations of arsenic range from
1.0 milligram per Kilogram (mg/Kg) to 18 mg/Kg with a mean concentration of 2.07 mg/Kg. Arsenic
concentrations reported above PSRGs ranged from 0.746 mg/Kg in DRSP-4 to 1.40 mg/Kg in DRSP-5 are
well within the referenced naturally occurring arsenic ranges, and it is the opinion of ECS that the arsenic
concentrations reported as a result of this assessment are naturally occurring.
Laboratory analysis of the six (6) soil samples submitted for laboratory analysis detected barium,
cadmium, chromium (total), lead, selenium, and mercury at concentrations above their laboratory
reporting limits but below their respective PSRGs.
Based on the laboratory results of the soil samples collected and a review of pre-existing site soil
conditions, the virgin stockpiled soil material set aside at the Double R Landfill appears to be compatible
with Wright's Executive Sales II soil. As such ECS respectfully requests that Brownfields provide return
correspondence indicating their approval of the request for import.

Receipt
The samples were received on 12/17/2022 11:00 AM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperatures of the 2 coolers at receipt time were 1.6°C and 1.6°C
GC/MS VOA
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
GC/MS Semi VOA
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
Herbicides
Method 8151A: The laboratory control sample (LCS) for preparation batch 680-756546 and analytical batch 680-758073 recovered outside
control limits for the following analyte: MCPP. This analyte was biased high in the LCS and was not detected in the associated samples;
therefore, the data has been reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
Pesticides
Method 8141A: The following samples DRSP-1 (680-227906-1), DRSP-2 (680-227906-2), DRSP-3 (680-227906-3), DRSP-4
(680-227906-4), DRSP-5 (680-227906-5), DUP-1 (680-227906-6), (680-227906-C-1 MS) and (680-227906-C-1 MSD) in preparation batch
280-597585 contain a small bi-layer in their final volume. Method 8141A.
Method 8141A: The surrogate recovery for the following samples in preparation batch 280-597585 and analytical batch 280-597737 was
outside acceptance limits (low biased) on the primary column: DRSP-3 (680-227906-3), DRSP-4 (680-227906-4) and DRSP-5
(680-227906-5). The recovery is within acceptance limits on the other column, indicating that the extraction process was in control.
Method 8141A: Surrogate recovery for the following samples in preparation batch 280-597585 and analytical batch 280-597737 was
outside control limits: DRSP-2 (680-227906-2) and DUP-1 (680-227906-6). Evidence of matrix interference is present; therefore,
re -extraction and/or re -analysis was not performed.
Method 8141A: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 280-597585 and analytical batch
280-597737 were outside control limits for one or more analytes, see QC Sample Results for detail. Sample matrix interference and/or
non -homogeneity are suspected because the associated laboratory control sample (LCS) recovery is within acceptance limits.
Method 8141A: The laboratory control sample (LCS) for preparation batch 280-597585 and analytical batch 280-597737 recovered low
outside control limits for the following analytes: EPN, Ethoprop, Ethyl Parathion, Fensulfothion, Fenthion and Trichloronate. The client
sample is out of hold for RX.
Method 8141A: The continuing calibration verification (CCV) associated with preparation batch 280-597585 and analytical batch
280-597737 recovered outside acceptance criteria, low biased, for Phorate and Ethoprop . 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.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
HPLC/IC
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
Metals
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

QUALIFIERS
Project: WRIGHT'S EXECUTIVE SALES 10039
Pace Project No.: 92678139
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
IH This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.
L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.
N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.
