1 Executive Summary
On behalf of Chevron Environmental Management Company (CEMC), Arcadis U.S., Inc. (Arcadis) is pleased to
submit this Groundwater Monitoring Report – First Quarter 2023 (report). This report summarizes the groundwater
monitoring/sampling completed between January 24 and 27, 2023 at the former Chevron facility (Gulf Oil
Company #205513; the site; Incident #14873) located at 600 South Main Street in High Point, North Carolina. It
has been established that because Ilderton Oil (additional responsible party) had dissolved in 2012, North
Carolina Department of Environmental Quality (NCDEQ) Underground Storage Tank (UST) Section, Division of
Waste Management, Winston-Salem Regional Office would take over Incident #14874 under the state lead
program. It has also been proposed by NCDEQ that CEMC would clean up 1,2-dichloroethane (1,2-DCA) and
ethylene dibromide (EDB) concentrations to below the Gross Contamination Levels (GCLs), and once 1,2-DCA
and EDB were below the GCLs, NCDEQ would assume the remaining liability at the site.
The previous groundwater samples were collected in July 2022 and the results were submitted in the
Groundwater Monitoring Report – Third Quarter 2022, dated January 26, 2023. NCDEQ issued an
Acknowledgement of Report Receipt on February 6, 2023 and requested the next semiannual groundwater
monitoring event be completed in the first quarter of 2023 with a report summarizing data be submitted by March
31, 2023.
Groundwater data/samples collected between January 23 and 27, 2023 indicate methyl tertiary butyl ether
(MTBE) concentrations were above GCLs in one well (MW-8), and benzene concentrations were above GCLs in
four wells (MW-2, MW-7, and MW-8 and MW-9). This report was prepared in accordance with the NCDEQ
cleanup requirements pursuant to Title 15A North Carolina Administrative Code 2L, Title 15A Department of
Environmental Quality 0407(d) Risk-based Assessment and Corrective Action for Petroleum USTs for
intermediate risk. Regulatory correspondence is included in Appendix A.
2 Site Location and Characterization
The site is located at the southwest corner of Grimes Avenue and South Main Street in High Point, North
Carolina, as shown on the United States Geologic Survey (USGS) Topographic Quadrangle for High Point West
(Figures 1 and 2). High Point is located in the southwestern portion of Guilford County, North Carolina. The area
is urban in character and primarily commercial to the north, east, and south of the site. The area to the west is a
combination of commercial and residential. The local land use map is included on Figure 2.
The site currently operates as a retail oriental rug supplier, consisting of a large showroom and warehouse
structure with an asphalt parking lot. A two-door warehouse delivery bay exists on the southeast side of the facility
along Taylor Avenue. Additional customer and employee parking is situated along Taylor Avenue on the
southeast side of the property. The current site structure encompasses an area much larger than the original retail
petroleum station. At the time when the site operated as a petroleum retail station, the legal deed reported the site
dimensions as approximately 0.33 acre. The current property is greater than one acre in size and is listed as 600
South Main Steet.
The properties contiguous to the west were zoned as residential multi-family, although an area of commercial
properties was also shown as located to the west of the site. Beyond the immediate vicinity of the site, most
properties in the High Point Main Street area were shown to be zoned as commercial (2022 Arcadis). A site map
showing former site features and underground storage tank data is included on Figure 3.

2.1 Facility Ownership and Well Installation History
Based on the information provided in the Phase I Environmental Site Assessment (ENSCI Environmental, Inc.
1995), the site was most likely used for residential purposes prior to 1929. In 1929, Gulf Oil purchased the
property, and USTs were installed at some point between 1929 and 1938, when they are evident on aerial
photographs of the area. Three 6,000-gallon USTs (ID numbers 1, 2, and 3) used for storage and distribution of
gasoline were installed in the UST field located on the northwest portion of the property in 1971. In 1979, Ilderton
Oil purchased the property and the existing 6,000-gallon USTs. Ilderton Oil operated USTs 1, 2, and 3 until they
were removed and replaced in October 1988 with three new 6,000-gallon USTs (ID numbers 11, 12, and 13). Gulf
Oil and its successors never owned or operated USTs 11, 12, and 13. In October 1995 and prior to the sale of the
property, Ilderton Oil removed USTs 11, 12, and 13. During these removal activities, seven additional USTs were
encountered and removed. Five 1,000-gallon USTs (ID numbers 4, 5, 6, 7, and 8), which appeared to have been
used for storage and distribution of gasoline, were encountered in a UST pit located on the northeastern portion of
the property. One 650-gallon UST used for the storage of used oil, and one 750-gallon UST used for the storage
of kerosene were located in a UST pit on the southern portion of the property. The seven additional USTs were
owned and operated by Gulf Oil and had previously been abandoned in place. A summary of USTs previously
located at the site is included in Table 1, and a summary of UST ownership is included in Table 2.
Between June 13 and 14, 2005, representatives of Blasland, Bouck and Lee, Inc. (BBL) and Geologic
Exploration, Inc. (GEX) (a North Carolina licensed well driller) installed groundwater monitoring wells MW-1,
MW-2, and MW-3 (BBL 2005). Between September 13 and 14, 2005, wells MW-5 and MW-6 were installed at
locations expected to be downgradient from the former Gulf Oil gasoline UST area as specified in the UST
Section Guidelines, and deep well MW-4D was installed adjacent to monitoring well MW-2 (BBL 2005). Between
February 24 and 25, 2014, representatives of Arcadis and GEX installed monitoring wells MW-7, MW-8, and
MW-9 (Arcadis 2014).
3 Receptor Information
A sensitive receptor survey was completed in April 2011. Potable water is obtained from a municipal supply in the
area of the site. Additionally, no potable water wells were identified within 1,500-feet of the site. The nearest
surface water body is an intermittent tributary of the Richland Creek, which has its headwater approximately
2,500-feet to the west of the former UST areas (Arcadis 2022).
4 Geology and Hydrogeology
The geology and hydrogeology for this area and the site are summarized below.
4.1 Regional Geology and Hydrogeology
The site is located within the Piedmont Physiographic Province in central North Carolina, which is characterized
by gently rolling landscape and broad ridges that lie between the Coastal Plain to the east and the Blue Ridge
Mountains to the west. The site is located within the Carolina Slate Belt. Rocks of this area generally consist of
metamorphosed igneous intrusive granitic rock ranging in age from 520 to 650 million years old (Brown, et al.
1985). The primary rock type in the area is metamorphosed granite with some intrusions of granodiorite and
Groundwater Monitoring Report – First Quarter 2023

2023.03.31 Chevron 205513 1Q2023 GMR.docx 3
quartz diorite. This rock is best described as white to gray, and fine to coarse grained with massive foliation
(Carpenter 1982). Weathering of the rock in this area produces an overlying soil material identified as saprolite
which resembles soil but retains some of the structure of the parent bedrock. Saprolite is produced by chemical
weathering of the underlying crystalline rock. Saprolite grades with depth to a semi-consolidated material known
as partially weathered rock (PWR).
Regionally, groundwater is found in saprolite, PWR, and underlying bedrock. Typically, these units may behave
as separate, unconfined, and semi-confined units within the aquifer system. PWR can be included as part of the
unconfined unit because it reacts hydraulically with saprolite. The saprolite and PWR typically have the capacity
to store large volumes of groundwater and act as a groundwater reservoir due to their high porosity relative to the
underlying bedrock unit. Groundwater storied in the saprolite generally flows horizontally toward surface water
features mimicking the local topography. Metavolcanic rocks generally have almost no porosity features such as
joints and fractures that contain groundwater. Groundwater flow within bedrock fractures is controlled by the
number, size, spacing, orientation, and interconnectedness of the fractures (USGS 1997).
4.2 Site Geology
Based on data collected during previous monitoring well installations at the site, surficial soil and saprolite are
present from the ground surface to approximately 58 below ground surface (bgs) and consist of a clayey to sandy
silt.
5 Groundwater Monitoring
Groundwater sampling at the site was completed as summarized below.
5.1 Groundwater Gauging
On January 23, 2023, the nine site monitoring wells were gauged with an oil/water interface probe to measure
depth to groundwater, and phase separated hydrocarbon (PSH) if present. Depths to water ranged from 15.80
feet below top-of-casing (btoc) in monitoring well MW-3 to 30.47 feet btoc in monitoring well MW-6. The
corresponding groundwater elevations ranged from 880.65 United States survey (US survey) feet in well MW-8 to
882.03 US survey feet in well MW-6. PSH was not detected in the monitoring wells during the January 2023
gauging activities. Historical groundwater gauging data indicate PSH has not been detected in the nine site
monitoring wells. Groundwater gauging data from the most recent event (January 2023) and the historical
groundwater gauging data are provided in Table 3; well construction and location information for the nine
monitoring wells are also summarized. Data from the January 2023 event indicated that, although relatively flat,
the horizontal component of shallow groundwater flow was to the south.A groundwater contour map is included
on Figure 4.
5.2 Groundwater Sampling
Upon completion of gauging activities, groundwater samples were collected for the nine site monitoring wells
between January 24 and 27, 2023, in accordance with the January 2023 sampling plan (Table 4). Groundwater
samples were collected using low flow sampling methodologies in accordance with current United States
Groundwater Monitoring Report – First Quarter 2023
www.arcadis.com
2023.03.31 Chevron 205513 1Q2023 GMR.docx 4
Environmental Protection Agency (USEPA) practices (USEPA 2013). Throughout the sampling process at each
well, temperature, pH, specific conductance, dissolved oxygen (DO), oxygen reduction potential (ORP), and
turbidity measurements were recorded using a calibrated multiparameter water quality meter and turbidity meter.
The field parameters and sampling information were recorded on field sampling logs and are included in
Appendix B. The groundwater samples were collected in pre-preserved laboratory-supplied containers and
immediately placed in a cooler with wet ice following collection. At the completion of sampling activities, the
samples were delivered in properly cooled and sealed containers to Pace Analytical National, a North Carolina
certified laboratory in Mount Juliet, Tennessee under appropriate chain-of-custody procedure. Samples were
analyzed for volatile organic compounds by USEPA Method 6200B and monitored natural attenuation (MNA)
parameters, including nitrate+nitrite nitrogen, nitrate nitrogen, nitrite nitrogen, ammonia nitrogen, total organic
nitrogen, total and ferric iron (+3), sulfate, sulfide, maximum dissolved methane, total organic carbon/biochemical
oxygen/chemical oxygen demand, alkalinity, carbon dioxide, and manganese.
Quality assurance/quality control (QA/QC) samples were collected to provide additional data for evaluating the
quality of the chemical analysis. QA/QC samples included a blind duplicate, a matrix spike/matrix spike duplicate
(MS/MSD), equipment rinsate blank, and a field blank.
The laboratory and data validation reports are included in Appendix C. Analytical data were validated in
accordance with USEPA National Functional Guidelines. Validation provided the means to determine the
reliability of the chemical analysis, the accuracy, and the precision of information acquired by the laboratory.
5.3 Groundwater Analytical Results
Groundwater concentrations exceeding the GCLs were detected in samples collected from four of the nine
monitoring wells during the January 2023 groundwater sampling event. Select groundwater results for the nine
wells are summarized in Table 5 and shown on Figure 5. Historical analytical results between June 2005 and
January 2023 are also summarized in Table 5.
Dissolved-phase benzene concentrations exceeded the GCL of 5,000 µg/L in groundwater samples collected
from monitoring wells MW-2 (12,000 micrograms per liter [µg/L]), MW-7 (7,500 µg/L), MW-8 (19,700 µg/L) and
MW-9 (8,240 µg/L). Dissolved phase 1,2-DCA and EDB concentrations did not exceed the GCL standard of 400
µg/L and 50 µg/L, respectively; however, reporting limits exceeded the GCL standards at wells MW-2, MW-7,
MW-8, and MW-9 due to laboratory sample dilution. The 1,2-DCA concentration reporting limit at well MW-8 was
reported at <2,500 µg/L; however, the method detection limit was reported at <205 µg/L, which is below the GCL.
The EDB reporting limits at wells MW-2, MW-7, and MW-9 were reported at <200 µg/L, <100 µg/L, and <200
µg/L, respectively; however, the method detection limits were reported at <25.2 µg/L, <12.6 µg/L, and <25.2 µg/L,
respectively, which are below the GCL. MTBE exceeded the GCL of 20,000 µg/L in the groundwater sample
collected from well MW-8 (75,800 µg/L). Benzene, 1,2-DCA, and EDB isoconcentration maps are provided on
Figures 6, 7, and 8.
MNA parameters listed in Section 5.2 of this report were required by NCDEQ UST Section guidance (NCDEQ
2022) and were analyzed during this baseline MNA sampling event; the data are summarized in Table 6. Overall,
the results indicate groundwater geochemistry is relatively reducing in areas with elevated VOC concentrations
(i.e., at monitoring wells MW-2, MW-7, MW-8, and MW-9) compared to other areas of the site. A summary of
select MNA results is provided below:
Groundwater Monitoring Report – First Quarter 2023
www.arcadis.com
2023.03.31 Chevron 205513 1Q2023 GMR.docx 5
Total organic carbon (TOC) was detected above the reporting limit in five of the nine wells sampled, with
concentrations ranging from 1,190 micrograms per liter (µg/L) at MW-3 to 261,000 µg/L at MW-8. TOC
concentrations were generally higher in wells with elevated VOC concentrations.
Nitrate-nitrogen was detected above the reporting limit in seven of the nine wells sampled, with
concentrations ranging from 271 µg/L at MW-2 (DUP) to 11,300 µg/L at MW-5. Concentrations of
nitrate-nitrogen were generally lower in wells with elevated VOC concentrations.
Total iron was detected above the reporting limit in the nine wells sampled with concentrations ranging
from 11 µg/L at MW-3 to 21,400 µg/L at MW-8. Ferrous (i.e., dissolved) iron was measured at six of the
nine wells sampled, with concentrations ranging from 50.0 J µg/L at MW-1 to 18,000 µg/L at MW-8.
Concentrations of ferrous iron were generally higher in wells with elevated VOC concentrations.
Sulfate was detected above the reporting limit in five of the nine wells sampled, with concentrations
ranging from 3,750 J µg/L at MW-9 to 100,000 µg/L at MW-3. Concentrations of sulfate were generally
lower in wells with elevated VOC concentrations.
Dissolved methane was detected above the reporting limit in four of the nine wells sampled, with
concentrations ranging from 85.7 µg/L at MW-8 to 199 µg/L at MW-2. Methane was only detected in wells
with elevated VOC concentrations.
As summarized above, MNA parameters indicate that groundwater geochemistry is generally reducing in wells
with elevated VOC concentrations. This includes reduced levels of nitrate and sulfate and increased levels of iron
and methane. Based on the results, samples from the nine wells will be collected during future semiannual
groundwater sampling events for the following MNA parameters: TOC, nitrate nitrogen, total iron, ferrous iron,
sulfate, and maximum dissolved methane. The proposed sampling plan is provided in Table 7.
6 Investigative Derived Waste
Purge water generated in January 2023 was containerized and appropriately labeled onsite in a 55-gallon
stainless steel drum. The waste will be transferred to an appropriate disposal facility pending profile sampling.
The waste manifest will be included in the next groundwater report.
7 Conclusion and Recommendations
During the January 2023 groundwater monitoring event groundwater elevations were gauged and
samples were collected from the nine site monitoring wells.
Benzene concentrations were detected above the GCL at four monitoring wells (MW-2, MW-7,
MW-8 and MW-9).
MTBE concentrations were detected above the GCL at monitoring well MW-8.
Semiannual groundwater monitoring will continue in 2023 (Third quarter) and 2024 and (first quarter); the
results will be provided in subsequent groundwater monitoring reports.
Arcadis recommends reducing the MNA parameters to include only TOC, nitrate nitrogen, total iron,
ferrous iron, sulfate, and maximum dissolved methane.
Data gathered during the semiannual groundwater monitoring events will be used for the corrective action
plan for the site. A remedial strategy will be proposed once sufficient data can be evaluated.

Notes:
Results reported in micrograms per liter (µg/L).
GCL = Gross Contamination Levels for Groundwater.
D = Concentration is based on a diluted sample analysis.
< = Not detected at or above indicated laboratory reporting limit
J = The compound was positively identified; however, the associated numerical value is an estimated concentration only.
B = The compound has been found in the sample as well as its associated blank, its presence in the sample may be suspect.
R = The sample results are rejected. The associated value is unusable due to significant quality control problems. The analysis provides no information as to whether the compound is present or not.
UB = Compound considered non-detect at the listed value due to associated blank contamination.
UJ = The compound was not detected above the reported sample quantitation limit. However, thereported limit is approximate and may or may not represent the actual limit of quantitation
NA = Not analyzed / not available.
Bold analytical values indicate concentration exceeds the applicable GCL.
DUP = Duplicate Sample Result

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
C4 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low.
Data is likely to show a low bias concerning the result.
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
J-The associated batch QC was outside the lower control limits; associated data has a potential negative bias.
K1 The sample dilutions set-up for the BOD/CBOD analysis did not meet the oxygen depletion criteria of at least 2 mg/L. Reported result is an estimated value.
K6 Glucose/glutamic acid BOD/CBOD was below method acceptance criteria.
P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit.
T8 Sample(s) received past/too close to holding time expiration.

ORGANIC ANALYSIS INTRODUCTION
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846
Methods 6200B. Data were reviewed in accordance with the method specified criteria, USEPA National
Functional Guidelines NFG for Organic Superfund Methods Data Review, EPA-540-R-20-005 (November
2020), with reference to the historical (USEPA Contract Laboratory Program National Functional
Guidelines for Organic Data Review, OSWER 9240.1-05A-P, October 1999, as appropriate).
The data review process is an evaluation of data on a technical basis rather than a determination of
contract compliance. As such, the standards against which the data are being weighed may differ from
those specified in the analytical method. It is assumed that the data package represents the best efforts
of the laboratory and had already been subjected to adequate and sufficient quality review prior to
submission.
During the review process, laboratory qualified and unqualified data are verified against the supporting
documentation. Based on this evaluation, qualifier codes may be added, deleted, or modified by the data
reviewer. Results are qualified with the following codes in accordance with USEPA National Functional
Guidelines:
• Concentration (C) Qualifiers
U The compound was analyzed for but not detected. The associated value is the compound
quantitation limit.
B The compound has been found in the sample as well as its associated blank, its presence in
the sample may be suspect.
• Quantitation (Q) Qualifiers
E The compound was quantitated above the calibration range.
D Concentration is based on a diluted sample analysis.
• Validation Qualifiers
J The compound was positively identified; however, the associated numerical value is an
estimated concentration only.
UJ The compound was not detected above the reported sample quantitation limit. However, the

VOLATILE ORGANIC COMPOUND (VOC) ANALYSES
1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
SW-846 6200B Water 14 days from collection to analysis Cool to <6 °C; preserved to
a pH of less than 2 s.u.
Note:
s.u. Standard units
All samples were analyzed within the specified holding time criteria.
2. Blank Contamination
Quality assurance (QA) blanks (i.e., method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
(common laboratory contaminant compounds are calculated at ten times) is calculated for QA blanks
containing concentrations greater than the sample detection limit (SDL). The BAL is compared to the
associated sample results to determine the appropriate qualification of the sample results, if needed.
Compounds 2-butanone (MEK) and toluene were detected in the associated QA blanks; however, the
associated sample results were greater than the BAL and/or were non-detect. Therefore, sample results
greater than the BAL resulted in the removal of the laboratory qualifier (B). No other qualification of the
sample results was required.
3. Surrogates/System Monitoring Compounds
All samples to be analyzed for organic compounds are spiked with surrogate compounds prior to sample
preparation to evaluate overall laboratory performance and efficiency of the analytical technique. VOC
analysis requires that all surrogates associated with the analysis exhibit recoveries within the laboratory-
established acceptance limits.
All surrogate recoveries were within the control limits.
4. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Analyses
MS/MSD data are used to assess the precision and accuracy of the analytical method. The compounds
used to perform the MS/MSD analysis must exhibit a percent recovery within the laboratory-established
acceptance limits. The relative percent difference (RPD) between the MS/MSD recoveries must exhibit
an RPD within the laboratory-established acceptance limits.
Note: The MS/MSD recovery control limits do not apply for MS/MSD performed on sample locations
where the compound concentration detected in the parent sample exceeds the MS/MSD concentration by
a factor of four or greater.
MS/MSD analysis was not performed on any of the samples from this SDG.

5. Laboratory Control Sample/Laboratory Control Sample Duplicate (LCS/LCSD) Analysis
The LCS/LCSD analysis is used to assess the precision and accuracy of the analytical method
independent of matrix interferences. The compounds associated with the LCS/LCSD analysis must
exhibit a percent recovery within the laboratory-established acceptance limits.
All compounds associated with the LCS/LCSD analysis exhibited recoveries within the control limits.
6. Field Duplicate Analysis
Field duplicate analysis is used to assess the overall precision of the field sampling procedures and
analytical method. A control limit of 30% for water matrices is applied to the RPD between the parent
sample and the field duplicate. In the instance when the parent and/or duplicate sample concentrations
are less than or equal to 5 times the RL, a control limit of two times the RL is applied for water matrices.
Field duplicate sample was not collected from this SDG.
7. System Performance and Overall Assessment
The case narrative noted that the CCVs for acrolein were outside the control limit with a high bias. The
associated field samples MW-3-W-20230126, MW-4D-W-20230126 and FB-2-W-20230126 were qualified
as estimated (UJ) for the above listed compound.
Overall system performance was acceptable. Other than for those deviations specifically mentioned in
this review, the overall data quality is within the guidelines specified in the method.

which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
(common laboratory contaminant compounds are calculated at ten times) is calculated for QA blanks
containing concentrations greater than the sample detection limit (SDL). The BAL is compared to the
associated sample results to determine the appropriate qualification of the sample results, if needed.
Compounds were not detected above the SDL in the associated blanks; therefore, detected sample
results were not associated with blank contamination.

INORGANIC ANALYSIS INTRODUCTION
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846
Methods 6010D, 2320B, 4500, 350.1, 3500Fe, 351.2, 353.2,410.4, 4500S2, 5210B, 9056A and 9060A.
Data were reviewed in accordance with USEPA National Functional Guidelines of October 2004.
The data review process is an evaluation of data on a technical basis rather than a determination of
contract compliance. As such, the standards against which the data are being weighed may differ from
those specified in the analytical method. It is assumed that the data package represents the best efforts
of the laboratory and that it was already subjected to adequate and sufficient quality review prior to
submission.
During the review process, laboratory qualified and unqualified data are verified against the supporting
documentation. Based on this evaluation, qualifier codes may be added, deleted, or modified by the data
reviewer. Results are qualified with the following codes in accordance with the USEPA National
Functional Guidelines:
• Concentration (C) Qualifiers
U The analyte was analyzed for but not detected. The associated value is the analyte
instrument detection limit.
J The reported value was obtained from a reading less than the reporting limit (RL), but
greater than or equal to the method detection limit (MDL).
• Quantitation (Q) Qualifiers
E The reported value is estimated due to the presence of interference.
N Spiked sample recovery is not within control limits.
* Duplicate analysis is not within control limits.
• Validation Qualifiers
J The analyte was positively identified; however, the associated numerical value is an
estimated concentration only.
UJ The analyte was not detected above the reporting limit. However, the reported limit is
approximate and may or may not represent the actual limit of detection.
UB Analyte is considered non-detect at the listed value due to associated blank contamination.
R The sample results are rejected.
Two facts should be noted by all data users. First, the "R" flag means that the associated value is
unusable. In other words, due to significant quality control (QC) problems, the analysis is invalid and
provides no information as to whether the compound is present or not. "R" values should not appear on
data tables because they cannot be relied upon, even as a last resort. The second fact to keep in mind is
that no compound concentration, even if it has passed all QC tests, is guaranteed to be accurate. Strict
QC serves to increase confidence in data but any value potentially contains error.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.

DATA REVIEW REPORT

ORGANIC ANALYSIS INTRODUCTION
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846
Methods 6200B. Data were reviewed in accordance with the method specified criteria, USEPA National
Functional Guidelines NFG for Organic Superfund Methods Data Review, EPA-540-R-20-005 (November
2020), with reference to the historical (USEPA Contract Laboratory Program National Functional
Guidelines for Organic Data Review, OSWER 9240.1-05A-P, October 1999, as appropriate).
The data review process is an evaluation of data on a technical basis rather than a determination of
contract compliance. As such, the standards against which the data are being weighed may differ from
those specified in the analytical method. It is assumed that the data package represents the best efforts
of the laboratory and had already been subjected to adequate and sufficient quality review prior to
submission.
During the review process, laboratory qualified and unqualified data are verified against the supporting
documentation. Based on this evaluation, qualifier codes may be added, deleted, or modified by the data
reviewer. Results are qualified with the following codes in accordance with USEPA National Functional
Guidelines:
• Concentration (C) Qualifiers
U The compound was analyzed for but not detected. The associated value is the compound
quantitation limit.
B The compound has been found in the sample as well as its associated blank, its presence in
the sample may be suspect.
• Quantitation (Q) Qualifiers
E The compound was quantitated above the calibration range.
D Concentration is based on a diluted sample analysis.
• Validation Qualifiers
J The compound was positively identified; however, the associated numerical value is an
estimated concentration only.
UJ The compound was not detected above the reported sample quantitation limit. However, the
reported limit is approximate and may or may not represent the actual limit of quantitation.
JN The analysis indicates the presence of a compound for which there is presumptive evidence to
make a tentative identification. The associated numerical value is an estimated concentration
only.
UB Compound considered non-detect at the listed value due to associated blank contamination.
N The analysis indicates the presence of a compound for which there is presumptive evidence to
make a tentative identification.
R The sample results are rejected.
Two facts should be noted by all data users. First, the "R" flag means that the associated value is
unusable. In other words, due to significant quality control (QC) problems, the analysis is invalid and
provides no information as to whether the compound is present or not. "R" values should not appear on
data tables because they cannot be relied upon, even as a last resort. The second fact to keep in mind is
DATA REVIEW REPORT
arcadis.com
that no compound concentration, even if it has passed all QC tests, is guaranteed to be accurate. Strict
QC serves to increase confidence in data but any value potentially contains error.

VOLATILE ORGANIC COMPOUND (VOC) ANALYSES
1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
SW-846 6200B Water 14 days from collection to analysis Cool to <6 °C; preserved to
a pH of less than 2 s.u.
Note:
s.u. Standard units
All samples were analyzed within the specified holding time criteria.
2. Blank Contamination
Quality assurance (QA) blanks (i.e., method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
(common laboratory contaminant compounds are calculated at ten times) is calculated for QA blanks
containing concentrations greater than the sample detection limit (SDL). The BAL is compared to the
associated sample results to determine the appropriate qualification of the sample results, if needed.
Compounds were not detected above the MDL in the associated blanks; therefore, detected sample
results were not associated with blank contamination.
3. Surrogates/System Monitoring Compounds
All samples to be analyzed for organic compounds are spiked with surrogate compounds prior to sample
preparation to evaluate overall laboratory performance and efficiency of the analytical technique. VOC
analysis requires that all surrogates associated with the analysis exhibit recoveries within the laboratory-
established acceptance limits.
All surrogate recoveries were within the control limits.
4. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Analyses
MS/MSD data are used to assess the precision and accuracy of the analytical method. The compounds
used to perform the MS/MSD analysis must exhibit a percent recovery within the laboratory-established
acceptance limits. The relative percent difference (RPD) between the MS/MSD recoveries must exhibit
an RPD within the laboratory-established acceptance limits.
Note: The MS/MSD recovery control limits do not apply for MS/MSD performed on sample locations
where the compound concentration detected in the parent sample exceeds the MS/MSD concentration by
a factor of four or greater.
MS/MSD analysis was performed on sample ID MW-5-W-20230127, exhibited acceptable recoveries and
RPDs.
5. Laboratory Control Sample/Laboratory Control Sample Duplicate (LCS/LCSD) Analysis
The LCS/LCSD analysis is used to assess the precision and accuracy of the analytical method
independent of matrix interferences. The compounds associated with the LCS/LCSD analysis must
exhibit a percent recovery within the laboratory-established acceptance limits.
DATA REVIEW REPORT
arcadis.com
All compounds associated with the LCS/LCSD analysis exhibited recoveries within the control limits.
6. Field Duplicate Analysis
Field duplicate analysis is used to assess the overall precision of the field sampling procedures and
analytical method. A control limit of 30% for water matrices is applied to the RPD between the parent
sample and the field duplicate. In the instance when the parent and/or duplicate sample concentrations
are less than or equal to 5 times the RL, a control limit of two times the RL is applied for water matrices.
Field duplicate sample was not collected from this SDG.
7. System Performance and Overall Assessment
The case narrative noted that the CCVs for acrolein were outside the control limit with a high bias. The
associated field samples MW-6-W-20230127 and MW-5-W-20230127 were qualified as estimated (UJ)
for the above listed compound.
Other than for those deviations specifically mentioned in this review, the overall data quality is within the
guidelines specified in the method.

DISSOLVED GASES ANALYSES
1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
RSK-175 Water 14 days from collection to analysis Cool to < 6 °C; pH > 10 with TSP
All samples were analyzed within the specified holding time criteria.
2. Blank Contamination
Quality assurance (QA) blanks (i.e. method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
(common laboratory contaminant compounds are calculated at ten times) is calculated for QA blanks
containing concentrations greater than the sample detection limit (SDL). The BAL is compared to the
associated sample results to determine the appropriate qualification of the sample results, if needed.
Compounds were not detected above the SDL in the associated blanks; therefore, detected sample
results were not associated with blank contamination.
3. Surrogates/System Monitoring Compounds
All samples to be analyzed for organic compounds are spiked with surrogate compounds prior to sample
preparation to evaluate overall laboratory performance and efficiency of the analytical technique.
Dissolved gases analysis requires that all surrogates associated with the analysis exhibit recoveries
within the laboratory-established acceptance limits.
All surrogate recoveries were within control limits.
4. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Analysis
MS/MSD data are used to assess the precision and accuracy of the analytical method. The compounds
used to perform the MS/MSD analysis must exhibit recoveries within the laboratory-established
acceptance limits. The relative percent difference (RPD) between the MS and MSD results must be within
the laboratory-established acceptance limits.
Note: The MS/MSD recovery control limits do not apply for MS/MSD performed on samples where the
compound concentration detected in the parent sample exceeds the MS/MSD concentration by a factor of
four or greater.
The MS/MSD analysis was performed on sample ID MW-5-W-20230127, exhibited acceptable recoveries
and RPDs.
5. Laboratory Control Sample (LCS) Analysis
DATA REVIEW REPORT
arcadis.com
The LCS analysis is used to assess the accuracy of the analytical method independent of matrix
interferences. The compounds associated with the LCS analysis must exhibit a percent recovery within
the laboratory-established acceptance limits.
All compounds associated with the LCS analysis exhibited recoveries within the control limits.
6. Field Duplicate Sample Analysis
The field duplicate analysis is used to assess the overall precision of the field sampling procedures and
analytical method. A control limit of 25% for water matrices is applied to the RPD between the parent
sample and the field duplicate. In the instance when the parent and/or duplicate sample concentrations
are less than or equal to five times the RL, a control limit of two times the RL is applied to the difference
between the results for water matrices.
Field duplicate sample was not collected from this SDG.
7. System Performance and Overall Assessment
Overall system performance was acceptable. Other than for those deviations specifically mentioned in
this review, the overall data quality is within the guidelines specified in the method.

approximate and may or may not represent the actual limit of detection.
UB Analyte is considered non-detect at the listed value due to associated blank contamination.
R The sample results are rejected.
Two facts should be noted by all data users. First, the "R" flag means that the associated value is
unusable. In other words, due to significant quality control (QC) problems, the analysis is invalid and
provides no information as to whether the compound is present or not. "R" values should not appear on
data tables because they cannot be relied upon, even as a last resort. The second fact to keep in mind is
that no compound concentration, even if it has passed all QC tests, is guaranteed to be accurate. Strict
QC serves to increase confidence in data but any value potentially contains error.

METALS ANALYSES
1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
SW-846 6010D Water 180 days from collection to analysis Preserved to a pH of less
than 2.
All samples were analyzed within the specified holding times.
2. Blank Contamination
Quality assurance (QA) blanks (i.e., method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
is calculated for QA blanks containing concentrations greater than the method detection limit (MDL). The
BAL is compared to the associated sample results to determine the appropriate qualification of the
sample results, if needed.
Analytes were not detected above the MDL in the associated blanks; therefore, detected sample results
were not associated with blank contamination.
3. Matrix Spike / Matrix Spike Duplicate (MS/MSD) /Laboratory Duplicate Analysis
MS/MSD and laboratory duplicate data are used to assess the precision and accuracy of the analytical
method.
3.1 MS/MSD Analysis
All metal analytes must exhibit a percent recovery within the established acceptance limits of 75% to
125%. The MS recovery control limits do not apply for MS performed on sample locations where the
analyte’s concentration detected in the parent sample exceeds the MS concentration by a factor of four or
greater.
The MS/MSD analysis was performed on sample ID MW-5-W-20230127, exhibited acceptable recoveries
and RPDs.
3.2 Laboratory Duplicate Analysis
The laboratory duplicate relative percent difference (RPD) criterion is applied when parent and duplicate
sample concentrations are greater than or equal to 5 times the RL. A control limit of 20% for water
matrices and 35% for soil matrices is applied when the criteria above is true. In the instance when the
parent and/or duplicate sample concentrations are less than or equal to 5 times the RL, a control limit of
one times the RL is applied for water matrices and two times the RL for soil matrices.
The laboratory duplicate analysis was not performed on any of the samples from this SDG.
4. Field Duplicate Analysis
DATA REVIEW REPORT
arcadis.com
Field duplicate analysis is used to assess the overall precision of the field sampling procedures and
analytical method. A control limit of 30% for water matrices and 50% for soil matrices is applied to the
RPD between the parent sample and the field duplicate. In the instance when the parent and/or duplicate
sample concentrations are less than or equal to 5 times the RL, a control limit of two times the RL is
applied for water matrices or three times the RL is applied for soil matrices.
Field duplicate sample was not collected from this SDG.
5. Laboratory Control Sample (LCS) Analysis
The LCS analysis is used to assess the accuracy of the analytical method independent of matrix
interferences. The analytes associated with the LCS analysis must exhibit a percent recovery between
the control limits of 80% and 120%.
The LCS analysis exhibited recoveries within the control limits.
8. System Performance and Overall Assessment
Overall system performance was acceptable. Other than for those deviations specifically mentioned in
this review, the overall data quality is within the guidelines specified in the method.

2. Blank Contamination
Quality assurance (QA) blanks (i.e., method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
is calculated for QA blanks containing concentrations greater than the method detection limit (MDL). The
BAL is compared to the associated sample results to determine the appropriate qualification of the
sample results, if needed.
All analytes associated with the QA blanks exhibited a concentration less than the MDL, with the
exception of the analytes listed in the following table. Sample results associated with QA blank
contamination that were greater than the BAL resulted in the removal of the laboratory qualifier (B) of

have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.

DATA REVIEW REPORT
arcadis.com
ORGANIC ANALYSIS INTRODUCTION
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846
Methods 6200B. Data were reviewed in accordance with the method specified criteria, USEPA National
Functional Guidelines NFG for Organic Superfund Methods Data Review, EPA-540-R-20-005 (November
2020), with reference to the historical (USEPA Contract Laboratory Program National Functional
Guidelines for Organic Data Review, OSWER 9240.1-05A-P, October 1999, as appropriate).
The data review process is an evaluation of data on a technical basis rather than a determination of
contract compliance. As such, the standards against which the data are being weighed may differ from
those specified in the analytical method. It is assumed that the data package represents the best efforts
of the laboratory and had already been subjected to adequate and sufficient quality review prior to
submission.
During the review process, laboratory qualified and unqualified data are verified against the supporting
documentation. Based on this evaluation, qualifier codes may be added, deleted, or modified by the data
reviewer. Results are qualified with the following codes in accordance with USEPA National Functional
Guidelines:
• Concentration (C) Qualifiers
U The compound was analyzed for but not detected. The associated value is the compound
quantitation limit.
B The compound has been found in the sample as well as its associated blank, its presence in
the sample may be suspect.
• Quantitation (Q) Qualifiers
E The compound was quantitated above the calibration range.
D Concentration is based on a diluted sample analysis.
• Validation Qualifiers
J The compound was positively identified; however, the associated numerical value is an
estimated concentration only.
UJ The compound was not detected above the reported sample quantitation limit. However, the
reported limit is approximate and may or may not represent the actual limit of quantitation.
JN The analysis indicates the presence of a compound for which there is presumptive evidence to
make a tentative identification. The associated numerical value is an estimated concentration
only.
UB Compound considered non-detect at the listed value due to associated blank contamination.
N The analysis indicates the presence of a compound for which there is presumptive evidence to
make a tentative identification.
R The sample results are rejected.
Two facts should be noted by all data users. First, the "R" flag means that the associated value is
unusable. In other words, due to significant quality control (QC) problems, the analysis is invalid and
provides no information as to whether the compound is present or not. "R" values should not appear on
data tables because they cannot be relied upon, even as a last resort. The second fact to keep in mind is
DATA REVIEW REPORT
arcadis.com
that no compound concentration, even if it has passed all QC tests, is guaranteed to be accurate. Strict
QC serves to increase confidence in data but any value potentially contains error.

VOLATILE ORGANIC COMPOUND (VOC) ANALYSES
1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
SW-846 6200B Water 14 days from collection to analysis Cool to <6 °C; preserved to
a pH of less than 2 s.u.
Note:
s.u. Standard units
All samples were analyzed within the specified holding time criteria.
2. Blank Contamination
Quality assurance (QA) blanks (i.e., method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
(common laboratory contaminant compounds are calculated at ten times) is calculated for QA blanks
containing concentrations greater than the sample detection limit (SDL). The BAL is compared to the
associated sample results to determine the appropriate qualification of the sample results, if needed.
Compounds methylene chloride, toluene and trichlorofluoromethane were detected in the associated QA
blanks; however, the associated sample results were non-detect. Therefore, no other qualification of the
sample results was required.
3. Surrogates/System Monitoring Compounds
All samples to be analyzed for organic compounds are spiked with surrogate compounds prior to sample
preparation to evaluate overall laboratory performance and efficiency of the analytical technique. VOC
analysis requires that all surrogates associated with the analysis exhibit recoveries within the laboratory-
established acceptance limits.
All surrogate recoveries were within the control limits.
4. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Analyses
MS/MSD data are used to assess the precision and accuracy of the analytical method. The compounds
used to perform the MS/MSD analysis must exhibit a percent recovery within the laboratory-established
acceptance limits. The relative percent difference (RPD) between the MS/MSD recoveries must exhibit
an RPD within the laboratory-established acceptance limits.
Note: The MS/MSD recovery control limits do not apply for MS/MSD performed on sample locations
where the compound concentration detected in the parent sample exceeds the MS/MSD concentration by
a factor of four or greater.
MS/MSD analysis was not performed on any of the samples from this SDG.
5. Laboratory Control Sample/Laboratory Control Sample Duplicate (LCS/LCSD) Analysis
The LCS/LCSD analysis is used to assess the precision and accuracy of the analytical method
independent of matrix interferences. The compounds associated with the LCS/LCSD analysis must
exhibit a percent recovery within the laboratory-established acceptance limits.

6. Field Duplicate Analysis
Field duplicate analysis is used to assess the overall precision of the field sampling procedures and
analytical method. A control limit of 30% for water matrices is applied to the RPD between the parent
sample and the field duplicate. In the instance when the parent and/or duplicate sample concentrations
are less than or equal to 5 times the RL, a control limit of two times the RL is applied for water matrices.
Field duplicate sample was not collected from this SDG.

The case narrative noted that the CCVs for acrolein were outside the control limit with a high bias. The
associated field sample MW-1-W-20230124 was qualified as estimated (UJ) for the above listed
compound.
Other than for those deviations specifically mentioned in this review, the overall data quality is within the
guidelines specified in the method.

All samples were analyzed within the specified holding time criteria.
2. Blank Contamination
Quality assurance (QA) blanks (i.e. method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
(common laboratory contaminant compounds are calculated at ten times) is calculated for QA blanks
containing concentrations greater than the sample detection limit (SDL). The BAL is compared to the
associated sample results to determine the appropriate qualification of the sample results, if needed.
Compounds were not detected above the MDL in the associated blanks; therefore, detected sample
results were not associated with blank contamination.
3. Surrogates/System Monitoring Compounds
All samples to be analyzed for organic compounds are spiked with surrogate compounds prior to sample
preparation to evaluate overall laboratory performance and efficiency of the analytical technique.
Dissolved gases analysis requires that all surrogates associated with the analysis exhibit recoveries
within the laboratory-established acceptance limits.
All surrogate recoveries were within control limits.
4. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Analysis
MS/MSD data are used to assess the precision and accuracy of the analytical method. The compounds
used to perform the MS/MSD analysis must exhibit recoveries within the laboratory-established
acceptance limits. The relative percent difference (RPD) between the MS and MSD results must be within
the laboratory-established acceptance limits.
Note: The MS/MSD recovery control limits do not apply for MS/MSD performed on samples where the
compound concentration detected in the parent sample exceeds the MS/MSD concentration by a factor of
four or greater.
The MS/MSD analysis was not performed on any of the samples from this SDG.
5. Laboratory Control Sample (LCS) Analysis
The LCS analysis is used to assess the accuracy of the analytical method independent of matrix
interferences. The compounds associated with the LCS analysis must exhibit a percent recovery within
the laboratory-established acceptance limits.
DATA REVIEW REPORT
arcadis.com
All compounds associated with the LCS analysis exhibited recoveries within the control limits.
6. Field Duplicate Sample Analysis
The field duplicate analysis is used to assess the overall precision of the field sampling procedures and
analytical method. A control limit of 25% for water matrices is applied to the RPD between the parent
sample and the field duplicate. In the instance when the parent and/or duplicate sample concentrations
are less than or equal to five times the RL, a control limit of two times the RL is applied to the difference
between the results for water matrices.
Field duplicate sample was not collected from this SDG.
7. System Performance and Overall Assessment
Overall system performance was acceptable. Other than for those deviations specifically mentioned in
this review, the overall data quality is within the guidelines specified in the method.

INORGANIC ANALYSIS INTRODUCTION
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846
Methods 6010D, 2320B, 4500, 350.1, 3500Fe, 351.2, 353.2,410.4, 4500S2, 5210B, 9056A and 9060A.
Data were reviewed in accordance with USEPA National Functional Guidelines of October 2004.
The data review process is an evaluation of data on a technical basis rather than a determination of
contract compliance. As such, the standards against which the data are being weighed may differ from
those specified in the analytical method. It is assumed that the data package represents the best efforts
of the laboratory and that it was already subjected to adequate and sufficient quality review prior to
submission.
During the review process, laboratory qualified and unqualified data are verified against the supporting
documentation. Based on this evaluation, qualifier codes may be added, deleted, or modified by the data
reviewer. Results are qualified with the following codes in accordance with the USEPA National
Functional Guidelines:
• Concentration (C) Qualifiers
U The analyte was analyzed for but not detected. The associated value is the analyte
instrument detection limit.
J The reported value was obtained from a reading less than the reporting limit (RL), but
greater than or equal to the method detection limit (MDL).
• Quantitation (Q) Qualifiers
E The reported value is estimated due to the presence of interference.
N Spiked sample recovery is not within control limits.
* Duplicate analysis is not within control limits.
• Validation Qualifiers
J The analyte was positively identified; however, the associated numerical value is an
estimated concentration only.
UJ The analyte was not detected above the reporting limit. However, the reported limit is
approximate and may or may not represent the actual limit of detection.
UB Analyte is considered non-detect at the listed value due to associated blank contamination.
R The sample results are rejected.
Two facts should be noted by all data users. First, the "R" flag means that the associated value is
unusable. In other words, due to significant quality control (QC) problems, the analysis is invalid and
provides no information as to whether the compound is present or not. "R" values should not appear on
data tables because they cannot be relied upon, even as a last resort. The second fact to keep in mind is
that no compound concentration, even if it has passed all QC tests, is guaranteed to be accurate. Strict
QC serves to increase confidence in data but any value potentially contains error.

METALS ANALYSES
1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
SW-846 6010D Water 180 days from collection to analysis Preserved to a pH of less
than 2.
All samples were analyzed within the specified holding times.
2. Blank Contamination
Quality assurance (QA) blanks (i.e., method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
is calculated for QA blanks containing concentrations greater than the method detection limit (MDL). The
BAL is compared to the associated sample results to determine the appropriate qualification of the
sample results, if needed.
Analytes were not detected above the MDL in the associated blanks; therefore, detected sample results
were not associated with blank contamination.
3. Matrix Spike / Matrix Spike Duplicate (MS/MSD) /Laboratory Duplicate Analysis
MS/MSD and laboratory duplicate data are used to assess the precision and accuracy of the analytical
method.
3.1 MS/MSD Analysis
All metal analytes must exhibit a percent recovery within the established acceptance limits of 75% to
125%. The MS recovery control limits do not apply for MS performed on sample locations where the
analyte’s concentration detected in the parent sample exceeds the MS concentration by a factor of four or
greater.
The MS/MSD analysis was not performed on any of the samples from this SDG.
3.2 Laboratory Duplicate Analysis
The laboratory duplicate relative percent difference (RPD) criterion is applied when parent and duplicate
sample concentrations are greater than or equal to 5 times the RL. A control limit of 20% for water
matrices and 35% for soil matrices is applied when the criteria above is true. In the instance when the
parent and/or duplicate sample concentrations are less than or equal to 5 times the RL, a control limit of
one times the RL is applied for water matrices and two times the RL for soil matrices.
The laboratory duplicate analysis was not performed on any of the samples from this SDG.

sample concentrations are less than or equal to 5 times the RL, a control limit of two times the RL is
applied for water matrices or three times the RL is applied for soil matrices.
Field duplicate sample was not collected from this SDG.
5. Laboratory Control Sample (LCS) Analysis
The LCS analysis is used to assess the accuracy of the analytical method independent of matrix
interferences. The analytes associated with the LCS analysis must exhibit a percent recovery between
the control limits of 80% and 120%.
The LCS analysis exhibited recoveries within the control limits.
8. System Performance and Overall Assessment
Overall system performance was acceptable. Other than for those deviations specifically mentioned in
this review, the overall data quality is within the guidelines specified in the method.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
B1 The blank depletion was greater than the recommended maximum depletion of 0.2mg/L.
J The identification of the analyte is acceptable; the reported value is an estimate.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
J-The associated batch QC was outside the lower control limits; associated data has a potential negative bias.
K5 The Dilution water D.O. depletion was > 0.2 mg/L.
K6 Glucose/glutamic acid BOD/CBOD was below method acceptance criteria.

DATA REVIEW REPORT

ORGANIC ANALYSIS INTRODUCTION
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846
Methods 6200B. Data were reviewed in accordance with the method specified criteria, USEPA National
Functional Guidelines NFG for Organic Superfund Methods Data Review, EPA-540-R-20-005 (November
2020), with reference to the historical (USEPA Contract Laboratory Program National Functional
Guidelines for Organic Data Review, OSWER 9240.1-05A-P, October 1999, as appropriate).
The data review process is an evaluation of data on a technical basis rather than a determination of
contract compliance. As such, the standards against which the data are being weighed may differ from
those specified in the analytical method. It is assumed that the data package represents the best efforts
of the laboratory and had already been subjected to adequate and sufficient quality review prior to
submission.
During the review process, laboratory qualified and unqualified data are verified against the supporting
documentation. Based on this evaluation, qualifier codes may be added, deleted, or modified by the data
reviewer. Results are qualified with the following codes in accordance with USEPA National Functional
Guidelines:
• Concentration (C) Qualifiers
U The compound was analyzed for but not detected. The associated value is the compound
quantitation limit.
B The compound has been found in the sample as well as its associated blank, its presence in
the sample may be suspect.
• Quantitation (Q) Qualifiers
E The compound was quantitated above the calibration range.
D Concentration is based on a diluted sample analysis.
• Validation Qualifiers
J The compound was positively identified; however, the associated numerical value is an
estimated concentration only.
UJ The compound was not detected above the reported sample quantitation limit. However, the
reported limit is approximate and may or may not represent the actual limit of quantitation.
JN The analysis indicates the presence of a compound for which there is presumptive evidence to
make a tentative identification. The associated numerical value is an estimated concentration
only.
UB Compound considered non-detect at the listed value due to associated blank contamination.
N The analysis indicates the presence of a compound for which there is presumptive evidence to
make a tentative identification.
R The sample results are rejected.
Two facts should be noted by all data users. First, the "R" flag means that the associated value is
unusable. In other words, due to significant quality control (QC) problems, the analysis is invalid and
provides no information as to whether the compound is present or not. "R" values should not appear on
data tables because they cannot be relied upon, even as a last resort. The second fact to keep in mind is
DATA REVIEW REPORT
arcadis.com
that no compound concentration, even if it has passed all QC tests, is guaranteed to be accurate. Strict
QC serves to increase confidence in data but any value potentially contains error.

VOLATILE ORGANIC COMPOUND (VOC) ANALYSES
1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
SW-846 6200B Water 14 days from collection to analysis Cool to <6 °C; preserved to
a pH of less than 2 s.u.
Note:
s.u. Standard units
All samples were analyzed within the specified holding time criteria.
2. Blank Contamination
Quality assurance (QA) blanks (i.e., method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
(common laboratory contaminant compounds are calculated at ten times) is calculated for QA blanks
containing concentrations greater than the sample detection limit (SDL). The BAL is compared to the
associated sample results to determine the appropriate qualification of the sample results, if needed.
Compounds were not detected above the SDL in the associated blanks; therefore, detected sample
results were not associated with blank contamination.
3. Surrogates/System Monitoring Compounds
All samples to be analyzed for organic compounds are spiked with surrogate compounds prior to sample
preparation to evaluate overall laboratory performance and efficiency of the analytical technique. VOC
analysis requires that all surrogates associated with the analysis exhibit recoveries within the laboratory-
established acceptance limits.
All surrogate recoveries were within the control limits.
4. Matrix Spike/Matrix Spike Duplicate (MS/MSD) Analyses
MS/MSD data are used to assess the precision and accuracy of the analytical method. The compounds
used to perform the MS/MSD analysis must exhibit a percent recovery within the laboratory-established
acceptance limits. The relative percent difference (RPD) between the MS/MSD recoveries must exhibit
an RPD within the laboratory-established acceptance limits.
Note: The MS/MSD recovery control limits do not apply for MS/MSD performed on sample locations
where the compound concentration detected in the parent sample exceeds the MS/MSD concentration by
a factor of four or greater.
MS/MSD analysis was not performed on any of the samples from this SDG.
5. Laboratory Control Sample/Laboratory Control Sample Duplicate (LCS/LCSD) Analysis
The LCS/LCSD analysis is used to assess the precision and accuracy of the analytical method
independent of matrix interferences. The compounds associated with the LCS/LCSD analysis must
exhibit a percent recovery within the laboratory-established acceptance limits.
DATA REVIEW REPORT
arcadis.com
All compounds associated with the LCS/LCSD analysis exhibited recoveries within the control limits.
6. Field Duplicate Analysis
Field duplicate analysis is used to assess the overall precision of the field sampling procedures and
analytical method. A control limit of 30% for water matrices is applied to the RPD between the parent
sample and the field duplicate. In the instance when the parent and/or duplicate sample concentrations
are less than or equal to 5 times the RL, a control limit of two times the RL is applied for water matrices.
Results for duplicate samples are summarized in the following table.

E The reported value is estimated due to the presence of interference.
N Spiked sample recovery is not within control limits.
* Duplicate analysis is not within control limits.
• Validation Qualifiers
J The analyte was positively identified; however, the associated numerical value is an
estimated concentration only.
UJ The analyte was not detected above the reporting limit. However, the reported limit is
approximate and may or may not represent the actual limit of detection.
UB Analyte is considered non-detect at the listed value due to associated blank contamination.
R The sample results are rejected.
Two facts should be noted by all data users. First, the "R" flag means that the associated value is
unusable. In other words, due to significant quality control (QC) problems, the analysis is invalid and
provides no information as to whether the compound is present or not. "R" values should not appear on
data tables because they cannot be relied upon, even as a last resort. The second fact to keep in mind is
that no compound concentration, even if it has passed all QC tests, is guaranteed to be accurate. Strict
QC serves to increase confidence in data but any value potentially contains error.

METALS ANALYSES
1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
SW-846 6010D Water 180 days from collection to analysis Preserved to a pH of less
than 2.
All samples were analyzed within the specified holding times.
2. Blank Contamination
Quality assurance (QA) blanks (i.e., method and rinse blanks) are prepared to identify any contamination
which may have been introduced into the samples during sample preparation or field activity. Method
blanks measure laboratory contamination. Rinse blanks measure contamination of samples during field
operations.
A blank action level (BAL) of five times the concentration of a detected compound in an associated blank
is calculated for QA blanks containing concentrations greater than the method detection limit (MDL). The
BAL is compared to the associated sample results to determine the appropriate qualification of the
sample results, if needed.
Analytes were not detected above the MDL in the associated blanks; therefore, detected sample results
were not associated with blank contamination.
3. Matrix Spike / Matrix Spike Duplicate (MS/MSD) /Laboratory Duplicate Analysis
MS/MSD and laboratory duplicate data are used to assess the precision and accuracy of the analytical
method.
3.1 MS/MSD Analysis
All metal analytes must exhibit a percent recovery within the established acceptance limits of 75% to
125%. The MS recovery control limits do not apply for MS performed on sample locations where the
analyte’s concentration detected in the parent sample exceeds the MS concentration by a factor of four or
greater.
The MS/MSD analysis was not performed on any of the samples from this SDG.
3.2 Laboratory Duplicate Analysis
The laboratory duplicate relative percent difference (RPD) criterion is applied when parent and duplicate
sample concentrations are greater than or equal to 5 times the RL. A control limit of 20% for water
matrices and 35% for soil matrices is applied when the criteria above is true. In the instance when the
parent and/or duplicate sample concentrations are less than or equal to 5 times the RL, a control limit of
one times the RL is applied for water matrices and two times the RL for soil matrices.
The laboratory duplicate analysis was not performed on any of the samples from this SDG.
4. Field Duplicate Analysis
DATA REVIEW REPORT
arcadis.com
Field duplicate analysis is used to assess the overall precision of the field sampling procedures and
analytical method. A control limit of 30% for water matrices and 50% for soil matrices is applied to the
RPD between the parent sample and the field duplicate. In the instance when the parent and/or duplicate
sample concentrations are less than or equal to 5 times the RL, a control limit of two times the RL is
applied for water matrices or three times the RL is applied for soil matrices.
Results for duplicate samples are summarized in the following table.
Sample ID/Duplicate ID Analyte Sample Result

MW-2-W-20230125 / DUP-01-W-20230125 Iron 11000 11200 2%
Manganese 12400 12800 3%
Notes:
AC = Acceptable
The calculated RPDs between the parent sample and field duplicate were acceptable.
5. Laboratory Control Sample (LCS) Analysis
The LCS analysis is used to assess the accuracy of the analytical method independent of matrix
interferences. The analytes associated with the LCS analysis must exhibit a percent recovery between
the control limits of 80% and 120%.
The LCS analysis exhibited recoveries within the control limits.
8. System Performance and Overall Assessment
Overall system performance was acceptable. Other than for those deviations specifically mentioned in
this review, the overall data quality is within the guidelines specified in the method.
