1 Introduction
On behalf of Chevron Environmental Management Company (CEMC), Arcadis U.S., Inc. (Arcadis) has prepared
this Subsurface Investigation Report (Report) for the property located at 680 West 1800 South, Beaver, Utah
(site); Division of Environmental Response and Remediation (DERR) Facility Identification 6000052; Release Site
ICY. The activities documented, herein, include the installation, development and sampling of two groundwater
monitoring wells completed in October 2024 in general accordance with the November 8, 2024, Groundwater
Monitoring Well Installation and Groundwater Sampling Work Plan (Work Plan). A site location map and site plan
are provided on Figures 1 and 2, respectively.
Subsurface Investigation Report

www.arcadis.com 2
2 Site Background
The site has operated as a retail gasoline service station since approximately 1955. The property was sold by
Chevron to Leland Black in March 1993. In 1993, the five original underground storage tanks (USTs) and
associated piping were removed from the site after petroleum hydrocarbons were detected in soil and
groundwater samples collected near the USTs. Later that year, new USTs and four dispenser islands were
installed in the same location as the former assets. This site (Assessor’s Parcel Number [APN] 03-0074-0009)
and the property to the north (APN 03-0045-0007; former Sinclair site) are both owned by Leland Black and
currently operate as one property containing a retail gas station branded as Beaver Valley Chevron. The station
encompasses the two properties: APN 03-0074-0009 and the former Sinclair site APN 03-0045-0007.
2.1 Site Description
The site is located on the northwestern corner of 525 W and Route 160 in Beaver, Utah (Figure 1). The closest
surface water body is South Creek, located approximately 900 feet north (upgradient) of the site (Leidos 2016).
The site is currently a Chevron-branded service station that operates three gasoline, and one diesel fuel USTs
located on the northeast corner of the property. Four pump islands are located in the central portion of the
property and two pump islands are located on the northern portion of the property (formerly operated as a
Sinclair, Figure 2).
2.2 Geology and Hydrogeology
The site is located in the Beaver River Valley, situated in the eastern portion of the Basin and Range
Physiographic Province. The Basin and Range Province is characterized by north-south trending normal fault
systems that form down-faulted, sediment-filled valleys separated by uplifted mountain ranges (Stokes 1977; Utah
Geological Survey 2021). The area around the site is characterized by alluvial fan deposits
(geomap.geology.utah.gov, 2025).
Observed soils on site include silty sands and gravels to approximately 16 feet below ground surface (bgs)
followed by a clayey silt to approximately 40 feet bgs. Sandy silt, coarse sands and clay were noted between 40
and 55 feet bgs.
2.3 Historic Soil Summary
In April 1993, in preparation for the property sale/transfer Chevron conducted a Phase II Property Assessment.
Monitoring wells MW-1 through MW-3 were installed and two soil borings, SB-1 and SB-2 were advanced.
Monitoring well MW-1 and soil boring SB-1 were located along the UST cavity, MW-2 and SB-2 were located near
the dispenser islands, and MW-3 was located near the former heating oil and waste oil USTs on the west side of
the building. Concentrations of constituents of concern (COC), including benzene, toluene, ethylbenzene, and
total petroleum hydrocarbons (TPH) gasoline range organics (GRO) were detected above the DERR initial
screening levels (ISLs) and Tier 1 screening levels (SLs) in soil samples collected from 20 feet bgs at MW-1, 16
Subsurface Investigation Report

www.arcadis.com 3
feet bgs at MW-2 and SB-2 at 25 feet bgs. COCs were detected above Tier 1 SLs in the initial groundwater
sample collected from MW-1 and ISLs in groundwater sample collected from MW-3. The historical soil analytical
results are summarized in Table 1.
The original USTs were closed in June 1993. Soil samples were collected in both UST cavities (fuel and waste
oil), the product piping and the dispenser islands. Samples labeled 1, 2 and 3 were collected form the waste oil
UST cavity and samples 4 through 12 were collected from the fuel UST cavity. The concentration of TPH in
closure soil samples 2, 4, 6 and 7 was above the ISL of 150 milligrams per kilogram (mg/kg) but below the Tier 1
SLs of 1,500 mg/kg. The concentration of remaining COCs were below the respective ISLs.
Monitoring wells MW-4 and MW-5 were installed in November 1993, downgradient monitoring wells MW-6 and
MW-7 were installed in April 2002, and monitoring well MW-8 was installed in June 2017. The concentrations of
COCs in soil were below the ISLs from wells MW-4 through MW-8.
2.4 Historical Groundwater Summary
Groundwater monitoring wells MW-1 through MW-7 were installed and sampled quarterly between 1994 through
1997. Wells were then sampled once in 1998, twice in 1999, three times in 2000, and then quarterly through the
fourth quarter 2002. Groundwater monitoring and sampling was not completed in 2003. From 2004 through 2016,
the wells were sampled generally annually (Leidos 2017a). Monitoring well, MW-8 was installed in June 2017 to
support further downgradient delineation efforts (Leidos 2017b). Due to an issue with the access agreement with
the property owner, the wells were not sampled between 2018 and October 2022. In October 2022, Arcadis
arrived on site to find that monitoring wells MW-1, MW-6, and MW-7 had been paved over and were inaccessible.
Arcadis returned to the site in June 2023 with a utility locating company to locate and uncover the wells.
Historically, petroleum impacts exceeding ISLs, and SLs have been detected in groundwater samples collected
from monitoring wells MW-1, MW-2, MW-3, MW-4, and MW-5. Current and historical concentrations of COCs in
groundwater are summarized in Tables 2 and 3.
Historical concentrations of benzene in groundwater samples collected from monitoring wells MW-1, MW-2, MW-
3, MW-4, and MW-5 have exceeded the Tier 1 SL. In recent sampling events prior to this scope of work, Benzene
concentrations continue to exceed the Tier 1 SL in groundwater samples collected from monitoring wells MW-1,
and MW-4. Benzene requires delineation to the north and northeast, upgradient of the source area. The
concentration of benzene in groundwater samples collected from all other wells is below the ISL, Tier 1 SL and/or
laboratory detection limits.
Historical concentrations of toluene in groundwater samples collected from MW-1 and MW-4 exceed the Tier 1
SL. In recent sampling events prior to this scope of work, the concentration of toluene in groundwater samples
collected from all monitoring wells is below the ISL, Tier 1 SL and/or laboratory detection limits.
Historical concentrations of total xylenes collected from monitoring well MW-1 exceed the Tier 1 SL. In the most
recent sampling events prior to this scope of work, the concentration of total xylenes in groundwater samples
collected from all monitoring wells is below the ISL, Tier 1 SL and/or laboratory detection limits.
Historical concentrations of TPH-GRO collected from monitoring wells MW-1, MW-4, and MW-5 exceed the Tier 1
SL. The concentration of TPH-GRO prior to this scope of work exceeds Tier 1 SL in groundwater samples
collected from monitoring wells MW-4, which required further delineation to the north and northeast. In the most
Subsurface Investigation Report

www.arcadis.com 4
recent sampling events prior to this scope of work, concentration of TPH-GRO exceeds the ISL in groundwater
samples collected from monitoring wells MW-1 and MW-2. The concentration of TPH-GRO in groundwater
samples collected from all other wells is below the ISL, Tier 1 SL and/or laboratory detection limits.
Historical concentrations of TPH–diesel range organics (DRO) collected from monitoring well MW-1 exceed the
Tier 1 SL. The concentration of TPH-DRO currently does not exceeds the Tier 1 SL in any groundwater samples.
However, the current concentration of TPH-DRO exceeds the ISL in groundwater samples collected from
monitoring well MW-1 and MW-4, requiring additional delineation to the north and northeast. The concentration of
TPH-DRO in groundwater samples collected from all other wells is below the ISL, Tier 1 SL and/or laboratory
detection limits.
The results from the historical sampling events indicated that the site is delineated to the southwest, downgradient
of the source area (Leidos 2017a, Arcadis 2024a); however, based on results from monitoring wells MW-1
through MW-8, delineation in the upgradient direction (i.e. north and northeast of MW-1 and MW-4) was needed.
Based on this, monitoring wells MW-9 and MW-10 were installed in October 2024 with the intent to achieve
upgradient delineation.

3 Objectives
The objective of the subsurface investigation, as presented in the 2024 Work Plan, was to delineate groundwater
and soil conditions upgradient of MW-1 and MW-4. Soil and groundwater samples were collected for analysis of
constituents of potential concern (COPC) related to retail petroleum facilities. Groundwater monitoring well
locations are presented on Figure 2.

4 2024 Field Investigation Activities
This section discusses the field activities completed to evaluate soil and groundwater quality north and northeast
of monitoring wells MW-1 and MW-4.
4.1 Pre-Field Activities
Prior to commencing intrusive work, the property owner was notified a minimum of 10 days prior to the start of
fieldwork.
Before initiating field activities, 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 [CFR] 1910.120).
On October 14, 2024, Arcadis contacted the Blue Stakes of Utah (811) to provide mark-outs of public utilities near
the proposed boring locations. The 811-request number was A42880712-00A. Earthview Technology, Inc.
(Earthview) was contracted to confirm utilities marked out during the 811and mark out additional underground
utilities to be avoided during subsurface investigation activities. Earthview utilized ground penetrating radar, radio
frequency detection to investigate and locate potential energized lines, and a metal detector to investigate
underground locations of potential utilities or soil boring conflicts. The areas surrounding originally planned
monitoring wells MW-9 and MW-10 were cleared prior to drilling.
4.2 Soil Boring Drilling and Sampling
On October 21 to 24, 2024 Arcadis directed boring advancement and monitoring installation activities conducted
by Cascade Drilling L.P. out of West Jordan, Utah. Two soil boring locations were precleared for utilities with an
air knife and soil vacuum truck to a minimum depth of five feet bgs. Borings were advanced with a TSI 150CC
compact-crawler sonic drill rig with a 6-inch diameter casing. Soil samples were collected directly from the core
barrel. The drilling stem was advanced in 2-foot intervals by sonic vibrations to a maximum depth of 55 feet bgs.
Soil samples were visually inspected, and representative samples were collected at approximately 2-foot intervals
into sealed Ziploc bags for field screening using a photoionization detector (PID). After pre-clearing to a depth of 5
feet bgs with the vacuum truck, soil samples were collected directly from the split-spoon sampler.
Each borehole was logged continuously using a combination of ASTM International (ASTM) standard D2488-06,
Wentworth, and the Unified Soil Classification System and screened for volatile organic compounds (VOCs) using
a calibrated PID. During drilling activities, detailed boring logs were kept for each soil boring and include date of
activities, drilling and sampling methods, borehole depth and size, lithology descriptions, samples collected, soil
headspace readings, and observed water levels. Well installation field notes are included in Appendix A. Soil
boring logs and monitoring well construction diagrams are included in Appendix B.
The laboratory analytical sampling intervals for each of the completed borings are presented in Table 4 below.
One blind duplicate soil sample was collected from each boring for data quality assurance. The parent sample for
BD-1-S-241022 is MW-10-S-40-42-241022 and BD-2-S-241023 parent sample is MW-9 -42-43-241023.

Immediately after exposing the soil core, analytical samples were collected as discrete samples using a small
diameter core sampler (e.g., Terra Core™ Sampler). The core, containing approximately 25 grams of soil, was
placed directly into laboratory prepared sample containers, then placed in a cooler with ice and kept at a
temperature of 2 to 6 degrees Celsius. Samples were submitted to Pace Analytical National (Pace) located in
Mount Juliet, Tennessee, under standard chain-of-custody protocol. Soil samples were analyzed for the following
constituents:
 TPH-GRO by United States Environmental Protection Agency (USEPA) Method 8015B;
 TPH-DRO and TPH-DRO with Silica Gel Treatment (SGT) by USEPA Method 8015B; and
 Benzene, toluene, ethylbenzene, xylenes, (BTEX), naphthalene and methyl tertiary-butyl ether (MTBE) by
USEPA Method 8260B.
After each use, down-hole equipment was triple rinsed with Alconox® or a similar solution, and then rinsed with
water, followed by a rinse with distilled water.
4.3 Groundwater Monitoring Well Installation
Monitoring wells MW-9 and MW-10 were installed after reaching total depth. The monitoring wells were
constructed of 2-inch-diameter schedule 40 polyvinyl chloride (PVC) with 0.01-inch factory-slotted screen and 2-
inch solid schedule 40 PVC riser. The permanent monitoring wells MW-9 and MW-10 were set at 55 and 52 feet
bgs, respectively, with a 15-foot screen interval. A sand pack (#20-40 silica sand) was placed from the bottom of
the borehole to approximately two feet above the screened interval. The sand pack was followed by hydrated
bentonite chips. The wells were fitted with sealing and locking well caps and are flush mounted. Traffic-rated well
boxes were installed to provide secure wellheads. Soil boring logs and monitoring well construction details are
included in Appendix B.

4.4 Well Development
Upon completion of the monitoring well installation, well development activities were conducted in accordance
with the approved Work Plan. Well development was performed by surging the well over the length of the
screened interval using a surge block, bailing out sediment that accumulated in the bottom of the wells, and then
purging the wells until the water was relatively free of suspended sediments. Purging was completed using a
submersible monsoon pump and purge water was containerized in new Department of Transportation-approved
55-gallon steel drums and sampled for disposal. A minimum of ten well volumes (approximately 60 gallons) of
water was pumped from each monitoring well.
4.5 Groundwater Monitoring and Sampling
The 2024 annual groundwater monitoring event was performed in accordance with the work plan presented in the
Work Plan (Arcadis 2024). Arcadis gauged monitoring wells MW-1 through MW-10 on November 20, 2024, and
collected groundwater samples on November 20 and 21, 2024. Field notes and groundwater gauging and
sampling forms are included in Appendix D.
Prior to sampling, monitoring wells were gauged to determine the presence/absence of light non-aqueous phase
liquid (LNAPL) and collect static groundwater elevation data for use in generating a groundwater potentiometric
map (Figure 4). Each monitoring well was first opened to allow the well to equilibrate and stabilize to atmospheric
conditions. The water level was then measured from the survey mark at the top of the casing using an electronic
oil/water interface probe that is accurate to 0.01 foot. Monitoring wells
MW-1 through MW-10 were purged and sampled using low-flow sampling methodology. Total depth of the well,
from the top of the casing, was measured after sampling had been completed to minimize impacts of turbidity
caused by resuspension of settled solids. Water quality parameters, including temperature, dissolved oxygen,
specific conductance, oxidation-reduction potential, and pH, were collected with a water quality meter during low
flow purging activities. Measurements were recorded in the field on groundwater gauging and sampling logs
(Appendix D).
Groundwater samples collected from each well were submitted to Pace in Mount Juliet, Tennessee. The samples
were analyzed for TPH-GRO and TPH-DRO with and without SGT by USEPA Method 8015D/GRO and 8015D
respectively, for BTEX, naphthalene, and MTBE by USEPA Method 8260B. Current and historical groundwater
monitoring and analytical data are presented in Tables 2 and 3. The laboratory report and chain-of-custody
documentation is included in Appendix E.
4.6 Investigative-Derived Waste
The investigative-derived waste (IDW) comprised of soil cuttings, purge water and equipment decontamination
water was contained in Department of Transportation approved new 55-gallon steel drums. The IDW was
appropriately labeled and stored onsite pending characterization. Soil cuttings and purged groundwater were
characterized by submitting waste samples to Pace for the following analysis:
 TPH-GRO and TPH-DRO by USEPA 8015;
Subsurface Investigation Report

www.arcadis.com 9
 Toxic Characteristic Leaching Procedure (TCLP) Resource Conservation and Recovery Act (RCRA) 8
metals by USEPA 1311/6010B, 7000 Series;
 TCLP Volatiles by USEPA 1311/8260B; and
 TCLP Semi-Volatiles by USEPA 1311/8270C.
Following receipt of laboratory analytical data, the IDW will be disposed off-site by Clean Harbors.

5 Soil Analytical Results
Analytical results for the soil sampling, performed during the installation of monitoring wells MW-9 and MW-10 are
summarized in Table 1 and Figure 3 and, are compared to the ISLs and risk-based corrective action Tier 1 SLs
for soil. The soil analytical report and chain-of-custody documentation are provided in Appendix C. Based on the
results of the soil sampling efforts, COCs were not detected above the ISLs and/or Tier 1 SLs, except for TPH-
GRO in the soil sample collected during the installation of MW-9 at a depth of 38 to 39.5 feet bgs. This depth at
MW-9 is at the groundwater interface and represents the capillary fringe indicating radial groundwater flow at the
downgradient source may be a contributing factor for impacts noted at this upgradient location. This is also
supported by the decreasing groundwater concentration noted between MW-9 and MW-1 (the source well). The
soil sample had a concentration of TPH-GRO of 402 mg/kg which exceeds the ISL of 150 mg/kg; however, the
soil appears vertically delineated as impacts, above regulatory criteria, were not noted within the saturated soil
and/or within the vadose zone at this location.

www.arcadis.com 11
6 Groundwater Sampling Results
Current groundwater analytical data are presented in Tables 2 and 3. Analytical results exceeding the DERR ISLs
and Tier 1 SLs are shown on Figure 5. Considering that the Former Sinclair property to the north and the site are
currently owned and operated as one facility (active retail gas station, Beaver Valley Chevron), Tier 1 SLs are
applied to samples collected at monitoring wells MW-1, MW-2, MW-4 and MW-9 and MW-10 as these wells are
located on the site and at least 30 feet from a building or property line. A summary of the analytical results follows:

Q = Sample was prepared and/or analyzed past holding time as defined in the method. Results is acceptable but should be
considered an estimate.
E = The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial
calibration.
J3 = The associated batch QC was outside the established quality control range for precision.

· There are no ISL exceedances in samples collected from wells MW-3, MW-5, MW-6, MW-7, and MW-8.
· As illustrated in Figure 5, the downgradient delineation has been successfully established; however, data
from the two newly installed monitoring wells indicate impacts in the upgradient direction. Based on the
observed concentrations, which exhibit a downward trend in the upgradient direction, it is likely that radial
groundwater flow originating from the source area (MW-1) has influenced the elevated concentrations
detected at MW-9 and MW-10.
· TPH-DRO and TPH-DRO with SGT were below the Tier 1 SL in the samples. TPH-DRO results with SGT
are included because the TPH-DRO analysis (Method 8015D) is not specific to hydrocarbons unless SGT
is used. Results of TPH-DRO with and without SGT are included in Tables 2 and 4. SGT is used to
exclude detections in groundwater that are from a natural organic carbon source, such as organic matter
or polar byproducts from degradation of petroleum hydrocarbons, allowing measurement of only the
Subsurface Investigation Report

www.arcadis.com 12
petroleum hydrocarbons of concern. Polar byproducts from diesel degradation are unregulated, generally
degrade quickly, and are considered less toxic to human health and the environment than the petroleum
hydrocarbons from which they are derived (Zemo and Foote 2003; Zemo et al. 2013; Patterson et al.
2020).
Polycyclic aromatic hydrocarbon results from previous groundwater monitoring are presented in Table 3. The
polycyclic aromatic hydrocarbon constituents were not analyzed during the current event.

7 Conclusions and Recommendations
In October 2024, subsurface investigation activities were completed. Two monitoring wells were installed to
evaluate the extent of soil and groundwater impacts upgradient of the source area. Monitoring wells were
advanced to a maximum completion depth of 55 feet bgs. Soil samples collected during well installation activities
indicate concentrations of COCs in one soil sample above DERR ISLs from MW-9, approximately 50 feet east,
and upgradient, of the former UST cavity. Soil impacts are vertically delineated in MW-9 and MW-10 with COC
concentrations below DERR ISLs and/or laboratory detection limits.
In November 2024, the monitoring well network was gauged and groundwater samples were collected.
Concentrations detected above the Tier 1 SLs in groundwater were reported at wells MW-1, MW-4, MW-9, and
MW-10 (TPH-GRO and/or benzene). Monitoring wells, MW-4 and MW-9 are located upgradient of the current
USTs as well as the former USTs and release area. Monitoring well MW-10 is located upgradient of the current
dispensers, on the former Sinclair property. Per data collected from wells MW-6 (21 years), MW-7 (21 years), and
MW-8 (6 years), concentrations have remained below Tier 1 SLs and DERR ISLs indicating the plume is not
migrating offsite at locations downgradient of the source area. As previously stated, based on the observed
concentrations at the newly installed wells, which exhibit a downward trend in the upgradient direction, it is likely
that radial groundwater flow originating from the source area (MW-1) has influenced the elevated concentrations
detected at MW-9 and MW-10.
Based on the site investigation results, the site use (onsite and upgradient of the site by the same property owner)
and long-term data indicating the former release is not migrating offsite and the depth of groundwater and soil
impacts (e.g. 38-40 feet) above Tier 1 SL or DERR ISLs (i.e. supports lack of potential risk for vapor intrusion,
ingestion, and utility workers), Arcadis recommends closing the site with remaining contamination in place.

Notes:
Bold = Result exceeds DERR ISL.
Shaded cell = Result exceeds Tier 1 SL.
Monitoring wells MW-1 through MW-8 were resurveyed on June 28, 2023 by EDM Partners. Vertical elevation data in NAVD 88, U.S. Survey Feet.
Benzene, toluene, ethylbenzene, total xylenes, naphthalene, and MTBE analyzed by USEPA Method 8260B
Acronyms and Abbreviations:
< = not detected at concentrations at or above the method detection limit. The metod detection limit is listed in the analytical report.
-- = not applicable
btoc = below top of casing
DERR ISL = Division of Environmental Response and Remediation Initial Screening Level
DTW = depth to water
GWE = groundwater elevation, based on site benchmark corrected for product if present, using a specific gravity of 0.75
mg/L = milligram per liter
MTBE = methyl tert-butyl ether
MW= Monitoring well
ND = not detected at concentrations at or above the method detection limit. The method detection limit is listed in the analytical report.
NM = not measured; top of casing survey data not available
Tier 1 SL = Tier 1 Screening Level. Only applicable when 1) no buildings, property boundaries or utility lines
within 30 feet, and 2) no water wells or surface water within 500 feet.
TOC = top of casing (assumed benchmark)
TPH-DRO = total petroleum hydrocarbons - diesel range organics analyzed by USEPA Method 8015B
TPH-GRO = total petroleum hydrocarbons - gasoline range organics analyzed by USEPA Method 8015B Modified
USEPA = United States Environmental Protection Agency
w/SGT = with silica gel treatment by USEPA Method 8015B/3511
Qualifiers:
B = The same analyte is found in the associated blank.
E= The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initialcalibration (ICAL). Value should be considered an estimate.
J = Estimated value above or equal to the method detection limit and below the reporting limit.
J3 = The associated batch quality control was outside the established quality control range for precision.
Q= Sample was prepared and/or analyzed past holding time as defined in the method. Since the sample was analyzed at less than two times the holding time the data is acceptable but should be considered an estimate.

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)

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.
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.
E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial
calibration (ICAL).
J The identification of the analyte is acceptable; the reported value is an estimate.
J1 Surrogate recovery limits have been exceeded; values are outside upper control limits.
J3 The associated batch QC was outside the established quality control range for precision.
Q Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations should be
considered minimum values.
