384394 Site Investigation and Groundwater Monitoring Report 1
1 Introduction
On behalf of Chevron Environmental Management Company (CEMC), Arcadis U.S., Inc. (Arcadis) has prepared
this Subsurface Investigation and Groundwater Monitoring Report (report) for the property located at 197 North
Main Street, Richfield, Utah; Division of Environmental Response and Remediation (DERR) Facility Identification
2000278, Release Site GZH (the Site; Figure 1). This report is being submitted to Utah Department of
Environmental Quality (UDEQ) DERR to satisfy a directive, dated October 25, 2023, for additional subsurface
investigation to delineate the downgradient petroleum hydrocarbon contamination in groundwater.
Site investigation and monitoring activities were completed in accordance with the December 19, 2023 Additional
Subsurface Investigation and Groundwater Monitoring Well Installation Work Plan (Work Plan) (Arcadis 2023b).
This report presents the results of monitoring well installation and soil and groundwater sampling activities
conducted at the site on April 12, 15, and April 22 through 24, 2024.
2 Site Description and Background
The following sections detail Site background information and general site information.
2.1 Site Description and Operational History
The Site is in a Downtown Redevelopment District of Richfield, Utah (Figure 1) and is currently owned by Rick S
Richfield Monuments LLC.
The Site was leased by Texaco Inc. (Texaco) and operated as a retail gas station between 1928 and 1972.
From 1972 to 1987, Conoco Inc. (Conoco) leased the Site. Between 1928 and 1972, five (5) underground storage
tanks (USTs) and a former dispenser island (located near the northeast corner of the Site) were documented. The
capacities ranged from 500-gallon to 2,000-gallon USTs and contained regular (leaded) gasoline, unleaded
gasoline, heating oil and/or waste oil.
Closure activities of the Site USTs in 1991 confirmed the presence of total petroleum hydrocarbons (TPHs) as
well as oil and grease in the subsurface. DERR was notified and the Site was assigned UST Facility Identification
No. 2000278.
Five (5) USTs were subsequently removed from the Site: one 2,000-gallon regular gasoline; one 2,000-gallon
unleaded gasoline; two 1,000-gallon regular (leaded) gasoline1; and one 1,000-gallon heating oil. In addition, a
500-gallon waste oil UST was abandoned-in-place. Additional details regarding the Site history and closure
activities are included in the Subsurface Investigation and Groundwater Monitoring Report (Arcadis 2021).
2.2 Site Investigation History
A soil investigation conducted in 1992 confirmed the presence of petroleum hydrocarbons as well as benzene,
toluene, ethylbenzene, xylenes (collectively BTEX) and naphthalene. Analytical results indicated elevated
concentrations of TPH were detected above the 1991 DERR Recommended Cleanup Levels (RCL). In addition,

1 One 1,000-gallon regular (unleaded) gasoline UST was discovered during UST removal activities as it had not been a previously
documented or known to exist UST.

www.arcadis.com
384394 Site Investigation and Groundwater Monitoring Report 2
BTEX and naphthalene concentrations were detected, but a 1991 DERR RCL did not exist at the time for these
analytes. The highest concentrations detected were in the vicinity of the dispenser island and former tank pits.
A subsequent site investigation was conducted by Arcadis in March and May 2021. Soil and groundwater sample
results were compared to Utah leaking underground storage tank (LUST) Initial Screening Levels (ISLs) and Tier
1 Screening Levels (UDEQ 2021). Concentrations of BTEX and TPH-diesel range organics (DRO) were detected
above applicable standards in soil samples collected onsite (BH-13 and MW-1). Detections above the ISLs were
not observed in soil samples collected offsite (MW-2 and MW-3). Groundwater samples collected in May and July
2021 detected concentrations of TPH-gasoline range organics (GRO), TPH-DRO, and benzene exceeding
applicable standards from onsite (BH-13 and MW-1) and offsite (MW-2). Additional details regarding the 1992 and
2021 Site investigation activities are included in the Subsurface Investigation and Groundwater Monitoring Report
(Arcadis 2021).
Groundwater monitoring activities (gauging and sampling) were completed quarterly at the onsite (MW-1) and
offsite (MW-2 and MW-3) monitoring wells between July 2021 and November 2022. As indicated in the latest
Groundwater Monitoring Report (Arcadis 2023a), CEMC and Arcadis discussed the path to closure for this site
with UDEQ DERR in first quarter 2023. The UDEQ DERR then issued their directive on October 25, 2023, for
additional subsurface investigation to delineate the downgradient petroleum hydrocarbon contamination in
groundwater (DERR 2023).
2.3 Site Setting
The Site topographically is relatively flat but slopes gently to the southeast toward the Richfield Canal and Sevier
River. The Site is located on the northwest corner of 200 North and North Main Street (US Highway 89). The
property consists of a building, parking area and sidewalks. Access to this private property is provided from one
entrance on North Main Street. The Site shares a property boundary with American National Insurance and
Related Services to the south. Other nearby buildings include State Farm Insurance, located across 200 North.
The buildings to the east, on the other side of North Main Street, include additional financial services, real estate
and various commercial retailers.
The Site location and topography map is presented in Figure 1 and the detailed Site layout map, with former and
current features, is presented in Figure 2.
3 Site Geology and Hydrogeology
3.1 Site Geology
The investigation activities completed by Arcadis in March and May 2021 as well as April 2024 determined that
the subsurface geology consisted of poorly graded very fine sands and clayey silts to silty clays. The local area
(onsite and offsite) is underlain predominantly by clay (silty and/or sandy), with interbedded layers of sand and
gravel, sand, silty sand, clayey sand, and clayey silt.

www.arcadis.com
384394 Site Investigation and Groundwater Monitoring Report 3
3.2 Site Hydrogeology
During monitoring activities completed on April 22, 2024, groundwater ranged from approximately 5304.88 feet
(MW-1) to 5304.43 (MW-4) feet in elevation. The interpreted groundwater flow direction is to the east/north-east.
4 Objectives
The objective of the subsurface investigation, as presented in the 2023 Work Plan, is to evaluate the extent of
groundwater impact downgradient of the site. The downgradient monitoring well location proposed was selected
based on results of the groundwater monitoring activities as well as concurrence from UDEQ DERR.
One monitoring well (MW-4) was installed to characterize groundwater. Soil samples were also collected for
analysis of constituents of concern related to the site. The soil boring and monitoring well locations are presented
on Figure 2.
5 Preliminary Field Investigation Activities
Prior to commencing intrusive work, a site-specific Health and Safety Plan (HASP) was prepared as required by
the Occupational Safety and Health Administration (OSHA) “Hazardous Waste Operations and Emergency
Response” guidelines (29 Code of Federal Regulations 1910.120). A copy of the HASP was maintained in the
field and reviewed by field staff and contractors before initiating any field activities.
On April 5, 2024, Arcadis contacted the Blue Stakes of Utah (811) to mark-out the public utilities near the
proposed monitoring well location (811-ticket number C40960308-00C). Arcadis also retained Ground Penetrating
Radar Systems, Inc. (GPRS), a private utility locating company, to locate and mark any potential subsurface
utilities not marked by the Blue Stakes program. The private utility clearance was also completed on April 5, 2024.
Utilities located at and adjacent to the Site are illustrated on Figure 3.
Due to the anticipated depth to water, a well permit was filed with Utah Division of Water Rights (UDWR) (i.e., a
permit is required when the total depth of the well is at or exceeds 30 feet below ground surface [bgs]). The
monitoring well was installed in accordance with the Utah Water Well Handbook (UDWR 2018). An encroachment
permit was required and approved through City of Richfield to install and sample monitoring well MW-4.
6 Investigation Activities
This section summaries the field activities and investigation-derived waste (IDW) associated with the investigation
and subsequent monitoring.
6.1 Soil Boring Drilling and Sampling
Drilling activities were conducted using a Direct Push Technology (DPT) drill rig operated by Cascade Drilling L.P.
(Cascade) (Utah Well Driller’s License # 626) during one mobilization on April 12, 2024. The first five feet of the
location was advanced by hand auger to clear for potential underground utilities.
While advancing the borehole, the drillers cored continuously using Macrocore. The borehole was logged
continuously for lithologic properties using a combination of Wentworth and the Unified Soil Classification System.

www.arcadis.com
384394 Site Investigation and Groundwater Monitoring Report 4
Soil intervals were visually inspected and representative samples were collected at approximately 1-foot intervals
into sealed Ziploc bags for field screening of volatile organic compounds (VOCs) using a calibrated
photoionization detector (PID). A detailed boring log was kept for the soil boring and includes date of activity,
drilling and sampling methods, borehole depth and size, lithology descriptions, olfactory and visual staining
observations (if any), samples collected, PID readings, and static water levels. The soil boring log is included in
Appendix A.
Soil sampling was conducted during the drilling activities in accordance with Utah’s Groundwater and Soil
Sampling Study Guide (UDEQ 2013) by an Arcadis Utah-Certified Soil and Groundwater Sampler. Samples were
collected from three intervals within the soil boring: one elevated PID interval (26 feet bgs); one capillary fringe
interval (34 feet bgs), and one saturated zone interval (40 feet bgs).
Soil samples were collected using laboratory-provided containers. Soil samples were labeled, placed in sealed
Ziploc® bags, immediately placed on ice in a chilled cooler, and transported to a National Environmental
Laboratory Accreditation Program (NELAP)-certified analytical laboratory under chain-of-custody procedures. Soil
samples were analyzed for the following constituents:
 TPH-GRO (carbon range 6 to 10), TPH-DRO (carbon range C10-C28) and TPH as oil range organics
(ORO) (carbon range C28-C40) by United States Environmental Protection Agency (USEPA) Method
8015; and
 BTEX, naphthalene, and methyl-tert butyl ether (MTBE) by USEPA Method 8260B.

Samples were submitted to Pace Analytical National (Pace) in Mount Juliet, Tennessee. The results are
discussed in Section 7 and are summarized in Table 1.
6.2 Groundwater Monitoring Well Installation and
Development
Monitoring well MW-4 was installed upon completion of drilling the boring to its total depth (50 feet bgs). The
monitoring well was constructed of 2.0-inch-diameter schedule 40 polyvinyl chloride (PVC) with a 0.010-inch
factory-slot screen and 2.0-inch solid schedule 40 PVC riser. Monitoring well MW-4 was set at 50 feet bgs with a
pre-packed 15-foot screen interval from 35 to 50 feet bgs. The annular space around the riser and screen was
backfilled from 12 feet to 50 feet with 16/30 sand pack, followed by granular hydrated bentonite from 1 to 12 feet
bgs and then grout to the ground surface. A flush mounted, traffic-rated steel well box with surrounding concrete
apron was installed at grade. The location of monitoring well MW-4 is illustrated on Figure 2. The construction log
and well driller’s report is included in Appendix A.
Following installation, a preliminary well development was conducted using a combination of surging and bailing.
During the April 12, 2024, field activities, MW-4 development was completed via pumping until water quality
parameters stabilized, in accordance with USEPA guidance (USEPA 1996). Well development forms and notes
are included in Appendix B.
At the conclusion of the installation activities, the monitoring well location was surveyed by a Utah-licensed land
surveyor (EDM Partners, Utah Professional Land Surveyor #4938730) on April 15, 2024. Vertical coordinate
information is referenced to the North American Vertical Datum of 1988 (NAVD 88). Horizontal coordinate

384394 Site Investigation and Groundwater Monitoring Report 5
information is referenced to the North American Datum of 1983 (NAD 83). The well survey is included in
Appendix C.
6.3 Groundwater Sampling
Groundwater samples were collected from existing monitoring wells MW-1, MW-2, MW-3, and the newly installed
MW-4 between April 22 and April 24, 2024. Depth to groundwater measurements were collected first on April 22,
2024, and ranged from 41.60 feet below top of casing (btoc) (MW-1) to 39.29 btoc (MW-3).
Low-flow groundwater sampling was conducted by Emma Rodgers, a Utah-Certified Soil and Groundwater
Sampler. Field parameters, including pH, temperature, conductivity, dissolved oxygen, and turbidity, were
measured during the groundwater sampling stabilization. Groundwater samples were collected using laboratory-
provided containers. The groundwater sample containers were labeled, placed in sealed Ziploc® bags,
immediately placed on ice in a chilled cooler, and transported to a NELAP-certified analytical laboratory under
chain-of-custody procedures.
The samples were analyzed for the following constituents:
 TPH- GRO (carbon range 6 to 10), TPH-DRO (carbon range C10-C28) and TPH-ORO (carbon range
C28-C40) by USEPA Method 8015; and
 BTEX, naphthalene, and MTBE by USEPA Method 8260B.

Samples were submitted to Pace in Mount Juliet, Tennessee. The results are discussed in Section 7 and are
summarized in Table 2.
6.4 Quality Assurance/Quality Control
Quality assurance procedures included decontamination of non-disposable equipment, use of disposable gloves,
care in sample collection, and proper chain-of-custody documentation. Quality control samples included
groundwater duplicate as well as trip blanks and equipment blanks.
6.5 Investigation-Derived Waste
IDW soil as well as groundwater and/or decontamination water generated during the investigation and monitoring
activities were containerized in separate Department of Transportation approved 55-gallon drums, labelled of their
contents, and are being stored in a secure location until pickup. Waste profile samples were collected during the
installation activities, and a waste profile will be generated and approved prior to pick up for disposal at a CEMC-
approved landfill.

7 Investigation Results
7.1 Screening Criteria
Soil and groundwater sample results were compared to Utah LUST ISLs and Tier 1 Screening Levels (UDEQ
2021). The applicable ISLs and Tier 1 Screening Levels are summarized for soil in Table 1.
7.2 Soil Results
A summary of soil analytical results is presented in Table 1. The soil analytical report and chain-of-custody
documentation is provided in Appendix D. The corresponding data validation and review report is included in
Appendix E. Analytical results for the soil samples collected during installation of monitoring well MW-4 were not
detected above the laboratory Reported Detection Limit (RDL) and were below applicable ISL’s with the exception
of TPH GRO which was detected above the Method Detection Limit (MDL), but below the applicable ISL’s.
7.3 Groundwater Results
This section summarizes the results of the April 2024 groundwater monitoring and sampling activities.
Groundwater elevations were calculated, based on the depth-to-water measurements, and a groundwater
elevation contour figure was generated (Figure 4). Contouring of the April 22, 2024, groundwater elevations result
in an interpreted groundwater flow direction to the east/north-east at a hydraulic gradient of approximately 0.002
feet per foot.
Based on the laboratory analytical results, groundwater constituents of concern were not detected at
concentrations exceeding the Utah LUST ISLs in samples collected from offsite wells MW-3 and MW-4. However,
TPH-GRO, TPH-DRO and benzene was detected at concentrations exceeding the corresponding Utah LUST
ISLs in groundwater samples collected offsite from MW-2 (benzene) and onsite from MW-1 (TPH-GRO, TPH-
DRO and benzene). The TPH and VOC analytical results are summarized in Table 2 and presented on Figure 5.
The following constituents were detected at concentrations exceeding the Utah LUST ISLs:
 TPH-GRO was detected above the ISL (1.0 milligrams per liter (mg/L)) in the groundwater sample at MW-
1 (7.42 mg/L).
 TPH-DRO was detected above the ISL (1.0 mg/L) in the groundwater sample at MW-1 (7.18 mg/L).
 Benzene was detected above the ISL (0.005 mg/L) in the groundwater samples at MW-1 (3.49 mg/L) and
MW-2 (0.00779 mg/L).

Figures 6 and 7 present hydrographs for TPH-GRO and benzene, respectively. These figures show results for
onsite well MW-1 and offsite wells MW-2, MW-3 and MW-4. Both TPH-GRO and benzene hydrographs show
seasonal fluctuation at offsite wells MW-2 and MW-3. The TPH-GRO concentrations remain below the Utah LUST
ISL during the fluctuations. However, although the latest benzene concentration at offsite well MW-2 exceeds the
Utah LUST ISL, the overall benzene concentration continues to show a stable to decreasing trend. Benzene
concentrations also exhibit a decreasing trend at offsite well MW-3.

www.arcadis.com
384394 Site Investigation and Groundwater Monitoring Report 7
Remaining COCs at offsite monitoring wells MW-2, MW-3 and MW-4 were not detected or detected at
concentrations less than ISLs.
Laboratory analytical reports are included in Appendix D. The corresponding data validation and review report is
included in Appendix E.
8 Conclusions
Benzene concentrations detected above the ISL for offsite well, MW-2, are stable to decreasing and the plume is
delineated with the installation of MW-4. Going forward, a second groundwater gauging and sampling event of
the four monitoring wells will be performed (planned for July 2024). Upon completion of the event, the analytical
results will be evaluated, and appropriate next steps proposed.

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
(dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry)Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry)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.
J The identification of the analyte is acceptable; the reported value is an estimate.
J4 The associated batch QC was outside the established quality control range for accuracy.

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.

DATA REVIEW REPORT

Organic Analysis Introduction
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846 Methods
8260B and 8015D/GRO and 8015 – SGT. 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), and CT DoE&EP
Laboratory Quality Assurance Quality Control Reasonable Confidence Protocols . (RCPs).
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 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 8260B Soil 48 hours from collection to extraction and 14 days from
extraction to analysis Cool to <6 °C;
All samples were analyzed within the specified holding time.
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 reporting limit (RL). 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 RL 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 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 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.
The MS/MSD analysis was not performed on sample 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.
Sample locations associated with LCS/LCSD analysis exhibiting recoveries outside of the control limits
presented in the following table.

Vinyl chloride AC >UL MW-4-S-34.00-240412
MW-4-S-40.00-240412
Note:
AC= Acceptable
UL= Upper limit
The criteria used to evaluate the LCS/LCSD recoveries are presented in the following table. In the case of
an LCS/LCSD deviation, the sample results are qualified as documented in the table below.

5. 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 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.
6. 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.

All samples were analyzed within the specified holding time.
2. Blank Contamination
Quality assurance (QA) blanks (i.e., method blanks, equipment blanks, and trip blanks) are prepared to identify any
contamination which may have been introduced into the samples during sample preparation or field activity.
Method blanks assess contamination introduced during sample preparation activities. Equipment blanks assess
the adequacy of the decontamination process and assess contamination from sampling, sample preparation, and
measurement processes.
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 Reporting limit (RL). The BAL is compared to the associated sample results to
determine the appropriate qualification of the sample results, if needed.
All compounds associated with the QA blanks exhibited a concentration less than the MDL, with the
exception of the compounds 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 data.
Sample results less than the BAL associated with the following sample locations were qualified as listed in
the following table.

DATA REVIEW REPORT

Organic Analysis Introduction
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846 Methods
8260B and 8015D/GRO and 8015 - SGT 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), and CT DoE&EP
Laboratory Quality Assurance Quality Control Reasonable Confidence Protocols . (RCPs).
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 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 8260B Water 14 days from collection to analysis Cool to <6 °C; preserved to a pH of less
than 2 s.u.
All samples were analyzed within the specified holding time.
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 reporting limit (RL). 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 RL 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.
Sample locations associated with surrogates exhibiting recoveries outside of the control limits presented in
the following table.

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 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.
The MS/MSD analysis was performed on sample MW-4-W-240422, MS/MSD analyses exhibited recoveries
and RPD within the control limit.
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.
5. 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 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.

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.
