WORK CONDUCTED THIS PERIOD [Third Quarter 2024]:

1. Conducted groundwater monitoring activities on July 11 and 12, 2024.
2. Prepared the July 2024 Groundwater Monitoring Report.

WORK PROPOSED NEXT PERIOD [Fourth Quarter 2024]:

No work is currently proposed for fourth quarter 2024. A down-gradient well installation and two
subsequent groundwater monitoring events were directed by State of Utah Division of Environmental
Quality, Department of Environmental Response and Remediation (DERR) on October 25, 2023. The
monitoring well installation and initial groundwater monitoring event were reported on June 27, 2024
(Arcadis 2024). This report provides the second and final groundwater monitoring activities, as approved
by DERR. A closure consideration is described below.

DISCUSSION
Site investigation and monitoring activities were completed in accordance with the December 19, 2023
Additional Subsurface Investigation and Groundwater Monitoring Well Installation Work Plan (Arcadis 2023)
and to satisfy an October 25, 2023 Utah Department of Environmental Quality (UDEQ) DERR directive for
additional subsurface investigation to delineate the downgradient petroleum hydrocarbon contamination in
groundwater (DERR 2023). As part of that directive, Arcadis installed a new monitoring well (MW-4) and
collected soil and groundwater samples for laboratory analysis in April 2024. The soil and initial groundwater
monitoring results were included in the Subsurface Investigation and Groundwater Monitoring Report
(Arcadis 2024).
Arcadis conducted the second groundwater monitoring event on July 11 and 12, 2024. Four monitoring
wells, MW-1, MW-2, MW-3, and MW-4 were gauged for Depth to Water (DTW). Following gauging activities,
wells MW-1 through MW-4 were purged and sampled using low-flow sampling methods until water levels
and field parameters (pH, electrical conductivity, dissolved oxygen, oxidation-reduction potential, and
temperature) stabilized. Flow rates were targeted to be 100 to 500 milliliters (mL) per minute using a bladder
pump. Groundwater purging and sampling was conducted by a Utah-Certified soil and groundwater
sampler. The groundwater monitoring field data sheets are included as Attachment A.
Groundwater samples were collected using laboratory-provided containers. Groundwater samples were
labeled, placed in sealed Ziploc® bags, immediately placed on ice in a chilled cooler, and transported to
Pace Analytical National (Pace) located in Mount Juliet, TN (NELAP-certified) under chain-of-custody
procedures.
The samples were analyzed for the following constituents:
 Total Petroleum Hydrocarbons – gasoline range organics (TPH-GRO) by United States
Environmental Protection Agency (USEPA) Method 8015D;
September 19, 2024

Page:
3/6
 Total Petroleum Hydrocarbons – diesel range organics (TPH-DRO) by USEPA Method 8015;
 Benzene, toluene, ethylbenzene, xylenes (BTEX), naphthalene, and Methyl Tertiary Buty Ether
(MTBE) by USEPA Method 8260B; and
 Oil and grease by USEPA Method 1664A.
Current and historical groundwater gauging and analytical data for the site are summarized in Table 1. The
site location and layout are presented on Figures 1 and 2, respectively; the groundwater elevation contours
for the site on July 11, 2024 are presented on Figure 3. Groundwater contours from the July 2024
groundwater monitoring event indicate the inferred groundwater flow direction is to the east/north-east at a
hydraulic gradient of approximately 0.003 feet per foot, as shown on Figure 3.
Per the Guidelines for Utah’s Corrective Action Process for Leaking Underground Storage Tanks (LUST;
DERR 2015), results for all four monitoring wells were compared to current DERR initial screening levels
(ISLs) and Tier 1 Screening Levels (SLs) (DERR 2021). 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, total petroleum hydrocarbon (TPH) as
gasoline range organics (GRO), TPH as diesel range organics (DRO) and benzene were detected at
concentrations exceeding the corresponding Utah LUST ISLs in groundwater samples collected offsite from
MW-2 and onsite from MW-1. Ethylbenzene was also detected at a concentration exceeding the
corresponding Utah LUST ISL in the groundwater sample collected from onsite well MW-1. The TPH and
VOC analytical results are summarized in Table 1 and presented on Figure 4.
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)) and the Tier 1 Screening
Level (10 mg/L) in the groundwater sample at MW-1 (16.6 mg/L).
 TPH-DRO was detected above the ISL (1.0 mg/L) and Tier 1 SL (10 mg/L) in the groundwater
sample at MW-1 (16.4 mg/L) and above the ISL at MW-2 (1.93 mg/L).
 Benzene was detected above the ISL (0.005 mg/L) and Tier 1 SL (0.300 mg/L) in the groundwater
sample at MW-1 (4.03 mg/L) and above the Tier 1 SL at MW-2 (0.125 mg/L).
 Ethylbenzene was detected above the ISL (0.7 mg/L) in the groundwater sample at MW-1 (0.737
mg/L).

Figures 5 and 6 present concentration versus time trend graphs for TPH-GRO and benzene as well as the
corresponding groundwater elevation at MW-1 and MW-2, respectively. Groundwater elevations during the
July 2024 event were measured approximately 2 to 5 feet higher than in the previous groundwater
monitoring event(s). Based on the concentration trends and groundwater elevations, residual mass may
exist in the “smear” zone (zone above average water elevation and high water elevation). However, based
on the age associated with a potential former Texaco release (~50 years) or former Conoco release (~32
years), seasonal concentration reduction over time is anticipated through natural attenuation processes.

It should be noted that MTBE has been detected, below the ISL and Tier 1 SL’s, in groundwater samples
collected from monitoring wells MW-1, MW-2, MW-3, and MW-4. In correspondence dated July 27, 2000,
September 19, 2024

Page:
4/6
Holland & Hart, LLP (Holland and Hart; a law firm representing Texaco) acknowledged the records provided
by DERR that identified Conoco leasing the property “from at least 1972 to 1987” and provided the Mutual
Cancellation of Lease by and between George Kay Staples, lessor, and Texaco, lessee, dated October 11,
1972. MTBE was not an additive to gasoline until 1979 (USEPA 2016). The detections of MTBE in
groundwater, even at low levels (e.g. below ISL and Tier 1 SL’s) is an indicator that a release, unrelated to
former Texaco operations, occurred at the site and/or in the vicinity of the site.

Laboratory analytical reports are included in Attachment B. The corresponding data validation and review
report is included in Attachment C.

Closure Consideration
Benzene concentrations were detected above the ISL, at its highest concentration since well installation
near the former source area at MW-1; however, based on the groundwater elevation (one of the highest
observed since well installation after a period of low elevations), residual mass likely exists in the smear
zone. Based on the age of the former release, ongoing natural attenuation processes (which are typically
supported by an influx of groundwater associated with snow melt and/or rainy season/rain events), and
current delineation, the overall plume appears stable. Based on the depth of the groundwater plume and
associated limited potential receptors, closure is still recommended for the site.

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.

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.
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
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.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.

DATA REVIEW REPORT
arcadis.com 4
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.
All compounds associated with the QA blanks exhibited a concentration less than the RL, 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.
Sample ID Compound Sample Result Qualification
MW-2-W-240712
BD-W-240712 Toluene (EB) Detected sample results >RL and <BAL “UB” at detected
sample concentration
Note:
RL Reporting limit
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 performed on sample ID MW-4-W-240711, exhibited recoveries and RPD within
the control limit with below exceptions.
Sample ID Compound MS Recovery MSD Recovery

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 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.

1. Holding Times
The specified holding times for the following methods are presented in the following table.
Method Matrix Holding Time Preservation
DRO SW 8015-SGT Water 14 days from collection to extraction and 40 days from
extraction to analysis Cool to <6 °C
GRO SW-846 8015 Water 14 days from collection to analysis Cool to <6 °C; preserved to
a pH of less than 2.
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 RL, 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.

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. The analysis
requires surrogate compounds exhibit recoveries within the laboratory-established acceptance limits.
All surrogate recoveries were within control limits.

RPD 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.
Results for duplicate samples are summarized in the following table.
The calculated RPDs between the parent sample and field duplicate were acceptable.

Inorganic Analysis Introduction
Analyses were performed according to United States Environmental Protection Agency (USEPA) SW-846
Method 1664A. Data were reviewed in accordance with the USEPA National Functional Guidelines NFG for
Inorganic Superfund Methods Data Review, EPA-540-R-20-006 (November 2020), with reference to the
historical (USEPA Contract Laboratory Program National Functional Guidelines for Inorganic Data Review,
OSWER 9240.1-05A-P, October 2004, 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 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 reported sample detection limit. However, the
reported limit is approximate and may or may not represent the actual limit of detection.
UB Analyte 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.
