GROUNDWATER MONITORING AND LIGHT NON-AQUEOUS PHASE LIQUID (LNAPL) RECOVERY REPORT
JACKS AUTO – RELEASE ID FQU
103 EAST CENTER STREET, MIDVALE UT

1 INTRODUCTION AND BACKGROUND
____________________________________________________________________________

This report presents the results of the groundwater monitoring activities performed at the former Jack’s
Southwest Collision (Jack’s Auto) Release Site FQU in Midvale, Utah on behalf of the Utah Department of
Environmental Quality (UDEQ or Client). Groundwater samples were collected on April 11-12 and
April 27, 2023, from ten (10) of the fifteen (15) groundwater monitoring wells proposed for sampling
under Work Assignment FQU-14-KLE and one (1) additional monitoring well, MW-5, approved for
sampling under Work Assignment FQU-14-KLE-B. Six (6) of the ten (10) proposed monitoring wells for
LNAPL recovery testing were monitored.

Groundwater sampling and Product testing were conducted in accordance with the UDEQ Division of
Environmental Response and Remediation (DERR) requirements by a Utah Certified Soil and
Groundwater Sampler, under the direction of Utah Professional Geologists and a Utah Certified UST
Consultant. The groundwater samples were collected from the existing monitoring wells to assess
petroleum hydrocarbon concentrations in groundwater at the Site and in the downgradient
groundwater flow direction, in accordance with Utah Groundwater Quality Protection Rule R317-6-6.15.
The Site location is indicated on Figure 1. Figure 2 depicts the current Site layout and groundwater
monitoring well locations with the associated groundwater elevations.

1.1 SITE DESCRIPTION
The Site is a former autobody shop which operated four underground storage tanks (USTs). In 1991, the
four USTs were removed from the Site. In 1989 and 1990, UST removal subsurface investigation work
was conducted at the west adjacent former Handimart property (now known as La Coqueta). Petroleum
releases affecting soil and groundwater at the two properties were reported to the UDEQ in 1991 and
1992. Sometime after 1991, a soil vapor extraction (SVE) system was installed at the former Handimart
property.

From 1993 through the present-day, additional groundwater monitoring wells, piezometers, and soil
borings were advanced at the Site and nearby properties to assess the plume. In 1993, Light
Non-Aqueous Phase Liquid (LNAPL or product) up to 6.6 feet thick was observed in several groundwater
monitoring wells and piezometers. In 1995, an LNAPL recovery system was installed at the Site. The
LNAPL recovery system was only operated for approximately one month due to limited LNAPL recharge
and recovery. Following shutdown of the LNAPL recovery system, bailing was the primary method used
for LNAPL recovery.

2 GROUNDWATER AND PRODUCT MONITORING
____________________________________________________________________________

2.1 GROUNDWATER GAUGING
On April 11 and 27, 2023, Kleinfelder personnel assessed the general condition of and gauged
twenty-five (25) groundwater monitoring wells. Four (4) of the proposed fifteen twenty-five (25)
groundwater monitoring wells were dry and therefore samples could not be collected. Kleinfelder field
personnel used an oil/water interface probe (OIP) to measure depth to product, depth to groundwater,
and total depth of each groundwater monitoring well. The OIP was decontaminated using a
non-phosphate wash solution and a distilled water rinse prior to use and between each well.

2.2 GROUNDWATER SAMPLING AND LAB ANALYSIS
On April 11-12 and 27, 2023, Kleinfelder collected groundwater samples from the eleven (11) monitoring
wells not containing product with sufficient water volume for sampling. The off-Site monitoring wells
that were sampled were selected to assess groundwater quality down/cross gradient of the historical
Jack’s Auto property.

Prior to sampling, a minimum of three well casing volumes were purged from each groundwater
monitoring well using a new factory-sealed disposable bailer and allowed to recover at least 80 percent
of the original static water level. Groundwater samples were collected with the disposable bailer
dedicated to each well. The purge water was not observed to have a visible sheen and was poured on an
intact asphalt surface and allowed to evaporate following sample collection.

The groundwater samples were placed in laboratory-supplied containers, labeled, immediately stored
on ice, and transported under chain-of-custody documentation to Pace Analytical National Center for
Testing and Innovation (Pace) in Mount Juliet, Tennessee for analysis of methyl tert-butyl ether,
benzene, toluene, ethylbenzene, xylenes, and naphthalene (MBTEXN) and total petroleum hydrocarbons
(TPH) as gasoline-range organics (TPH-GRO) by Environmental Protection Agency (EPA) Method 8260
and TPH as diesel-range organics (TPH-DRO) by EPA Method 8015. The laboratory groundwater
analytical reports and chain-of-custody documentation are included in Appendix A.

2.3 PRODUCT GAUGING AND RECOVERY
The depths to LNAPL (Product) and groundwater were measured on April 26, 2023, in the proposed
monitoring wells MW-5, MW-8, MW-12, MW-17, MW-21, MW-23, MW-24, MW-26, and B-4. Once
gauging was completed, Kleinfelder used weighted disposable bailers to remove LNAPL from each well.

The waste generated from the recovery of LNAPL was placed into a 55-gallon steel drum and picked up
for disposal by E.T. Technologies on April 26, 2023. Kleinfelder provided E.T. Technologies with the
density and flashpoint results of a waste characterization sample taken from MW-17 on April 12, 2023,
for proper disposal. The laboratory report for the waste characterization is included in Appendix A.

Kleinfelder returned to the monitoring wells where LNAPL was removed to document the depths to
LNAPL and groundwater one, two, four, seven, and eight weeks from the initial recovery in accordance
with Work Assignment FQU-14-KLE.

2.4 DEVIATIONS FROM THE APPROVED WORK PLAN
On April 26, 2023, Kleinfelder gauged monitoring well MW-5 for LNAPL recovery testing due to previous
detection; however, Kleinfelder personnel did not observe measurable LNAPL in the monitoring well and
acquired approval to add the well to the groundwater sampling event.

On April 26, 2023, Kleinfelder was unable to access monitoring wells MW-21, MW-24, and B-4 due to
the presence of abandoned or lived-in vehicles. Kleinfelder notified the Client of the anticipated
deviation, and the monitoring wells were approved to be excluded from the LNAPL gauging and
recovery task.

3 INVESTIGATION RESULTS
____________________________________________________________________________

Gauging data from the April 2023 groundwater monitoring event are presented in Table 1. Groundwater
analytical results for the April 2023 groundwater sampling event are presented in Table 2 and
summarized below. A potentiometric surface map, using data from the April 2023 gauging event, is
included as Figure 2. Figures 3 through 5 present iso-concentration maps for TPH-GRO, TPH-DRO, and
benzene, respectively.

3.1 GROUNDWATER GAUGING RESULTS
Based on the potentiometric surface map provided in Figure 2, the dominant groundwater flow
direction trends outward from MW-17 in all directions at a gradient of approximately 0.05 foot/foot
using the lowest groundwater elevation of 4314.42 feet above mean sea level (amsl) in MW-22 and
highest groundwater elevation of 4324.74 amsl in MW-17. Additional groundwater gradients calculated
from MW-17 and wells to the north, east, and south range from 0.04 to 0.08 foot/foot. Varying
groundwater gradients between the monitoring events could be influenced by the difference of LNAPL
thickness, the hydrocarbon density in monitoring wells, and the number of dry wells that Kleinfelder
observed during the current monitoring event. Depths to groundwater ranged from 35.18 feet below
ground surface (bgs) in MW-23 to 47.28 feet bgs in MW-1. Groundwater elevations for each of the
twenty-five (25) wells monitored during April 2023 are included on Table 1. The groundwater
potentiometric surface is presented in Figure 2.

Groundwater elevations were corrected for the presence of LNAPL using the formula:

PCWL = (TOC – WD) + (WD-PD) * (H Density / W Density)

Where PCWL is the product corrected water level, TOC is the top of casing elevation, WD is the depth to
water, PD is the depth to product, H Density is the hydrocarbon density of 0.80 grams per milliliter
(g/ml), and W Density of the water density of one g/ml. The hydrocarbon density of 0.80 g/ml was
selected based on the waste characterization result collected from MW-17 on April 12, 2023, and
analyzed by Pace. The laboratory report for the waste characterization is included in Appendix A.

3.2 GROUNDWATER ANALYTICAL RESULTS
The following presents a summary of the groundwater analytical results presented in Table 2 for the
monitoring wells sampled in April 2023. Historical analytical results containing the November 2022
analytical results are included in Table 3.

Concentrations of TPH-GRO were reported above the UDEQ DERR Initial Screening Level (ISL) of
one milligram per liter (mg/L) in the groundwater sample collected from on-Site monitoring wells MW-4
(reported at 8.73 mg/L). In addition to exceeding the ISL, on-Site monitoring wells MW-5 and MW-7
exceeded the UDEQ DERR Tier 1 Screening Level (SL) of 10 mg/L (reported at 23.1 and 11.9 mg/L,
respectively).

Concentrations of TPH-DRO were reported above the UDEQ DERR ISL of one mg/L in the groundwater
sample collected from on-Site groundwater monitoring wells MW-4 (reported at 3.17mg/L), MW-5
(reported at 7.09 mg/L), MW-6 (reported at 1.95 mg/L), and MW-7 (reported at 6.11 mg/L). In addition
to exceeding the ISL, the duplicate sample MW-35, taken from monitoring well MW-5, exceeded the
UDEQ DERR Tier 1 SL of 10 mg/L (reported at 11.1 mg/L).

Benzene was reported at concentrations exceeding the UDEQ DERR ISL of 0.005 mg/L in the
groundwater samples collected from on-site monitoring well MW-4 (reported at 0.0288mg/L), MW-5
(reported at 0.162 mg/L), and MW-7 (reported at 0.0930 mg/L). No concentrations of benzene were
reported above the UDEQ DERR Tier 1 SL of 0.3 mg/L.

Toluene, ethylbenzene, total xylenes, methyl tert-butyl ether, and naphthalene were not reported in
groundwater samples collected from the on or off-Site monitoring wells at concentrations above the
UDEQ DERR SLs. Isoconcentration maps of TPH-GRO, TPH-DRO, and benzene were drawn using the
Surfer® groundwater modelling application, and are included as Figures 3 through 5, respectively.

3.3 QUALITY ASSURANCE AND QUALITY CONTROL
Pace reported the qualifier “B” for TPH-DRO in monitoring wells MW-2, MW-3, and MW-13, indicating
TPH-DRO was detected in the associated laboratory method blank. The qualifier “B” indicates that the
results for TPH-DRO in these monitoring wells could be biased high. The reported concentrations have
been compared to the results from the November 2022 monitoring event and are generally similar. No
additional qualifiers were reported by Pace; therefore, the data is considered accurate.

Two (2) duplicate samples were collected for quality assurance (QA) purposes, DUP-1 from MW-6 and
MW-35 from MW-5. The Environmental Protection Agency (EPA) QA guidelines establish that the range
of quality in precision (the relative percent difference or RPD) between two measurements should not
exceed 20 percent for aqueous samples. TPH-DRO in MW-35 and MW-5 exceeded the EPA guideline for
precision with an RPD of 44.1. Benzene in DUP-1 and MW-6 exceeded the EPA guideline for precision
with an RPD of 28.9. The majority of RPDs for the parent and duplicate samples were within the EPA
guideline for precision in the majority of the analyses; therefore, the results are considered sufficiently
precise.

The laboratory report from Pace is included in Appendix A, and the RPDs are presented in Table 4.

3.4 LNAPL RECOVERY RESULTS
Measurable LNAPL thickness was present in six (6) monitoring wells MW-8, MW-12, MW-17, MW-20,
MW-23, and MW-26. As presented in Table 5, the LNAPL thickness prior to the recovery ranged from
0.13 feet in MW-23 to 1.66 feet in MW-17. The depth to groundwater decreased over the eight (8)
weeks by 0.21 to 2.22 feet.

The results from the product recovery testing from the six (6) monitoring wells with measurable LNAPL
in April 2023 are presented in Table 5 and summarized below:

• LNAPL thickness in monitoring well MW-8 was observed to be 0.55 feet in the initial gauging
event prior to recovery (Week 0) and gradually recovered to 0.47 feet in Week 8, approximately
85% of the original thickness.
• LNAPL thickness in monitoring well MW-12 was observed to be 0.57 feet in Week 0 and
gradually recovered to 0.38 feet in Week 8, approximately 67% of the original thickness.
• LNAPL thickness in monitoring well MW-17 was observed to be 1.66 feet in Week 0 and
gradually recovered to 1.06 feet, approximately 64% of the original thickness.
• LNAPL thickness in monitoring well MW-20 was observed to be 1.58 feet in Week 0. LNAPL
thickness fluctuated from 28% of the original thickness in Week 1, decreased to 8.9% of the
original thickness in Week 2, then increased to 17% and then 32% in Weeks 4 and 7,
respectively, and then decreased to 25% of the original thickness (0.39 feet) in Week 8.

• LNAPL thickness in monitoring well MW-23 was observed to be 0.13 feet in Week 0. LNAPL
thickness fluctuated from 23% of the original thickness in Week 1, then decreased to a
non-measurable thickness of LNAPL in Week 2, then increased to 31% and then 62% in Weeks 4
and 7, respectively, and then decreased to 38% of the original thickness (0.05 feet) in Week 8.
• LNAPL thickness in monitoring well MW-26 was observed to be 0.50 feet in Week 0. LNAPL
thickness fluctuated from 38% of the original thickness in Week 1, then increased to 40% in
Weeks 2 and 4, then decreased to 28% in Week 7, and increased to 30% of the original thickness
(0.15 feet) in Week 8.

The LNAPL gauging and recovery results are included in Table 5. Bar charts depicting the LNAPL recovery
over time are included in Figures 6 through 8.

4 CONCLUSIONS AND RECOMMENDATIONS
____________________________________________________________________________

4.1 CONCLUSIONS
Petroleum hydrocarbon impacts above the UDEQ DERR ISLs and Tier 1 SLs have been reported in
groundwater samples collected from the Jack’s Auto Site and in the hydraulically downgradient, off-Site
wells. The dominant groundwater flow direction trends radially outward from MW-17 at a gradient of
approximately 0.05 ft/ft using the lowest groundwater elevation of 4314.42 feet amsl in MW-22 and the
highest groundwater elevation of 4324.74 feet amsl in MW-17. Based on a comparison of the
November 2022 monitoring event, the wells exceeding the UDEQ DERR Tier 1 SLs is consistent. Based on
a comparison of wells exceeding the UDEQ DERR ISLs from the November 2022 monitoring event, the
groundwater contaminant plume has generally remained stable with the exception of TPH-DRO
migrating to the east (Kleinfelder, 2022).

Monitoring wells MW-8, MW-12, and MW-17 recovered 64-84% of their original LNAPL thickness within
the eight-week recovery test period, indicating that removal of LNAPL in these wells may provide
meaningful reduction in LNAPL mass at the Site. Monitoring wells MW-20, MW-23, and MW-26
recovered 25-38% of their original LNAPL thickness and fluctuated throughout the eight-week recovery
test period, indicating that LNAPL removal from these wells may not provide an efficient reduction in
LNAPL mass at the Site. Groundwater fluctuations throughout the eight-week LNAPL recovery test
period may also have influenced the LNAPL mobility and recovery in wells such as MW-20 and MW-23,
which recorded an increase in groundwater elevations by approximately two feet.

4.2 RECOMMENDATIONS
Kleinfelder recommends that the quarterly gauging and sampling of all wells be continued to further
evaluate seasonal fluctuations and exceedances of petroleum hydrocarbon screening levels and monitor
the perimeter of the free product plume. Kleinfelder also recommends installing additional groundwater
monitoring wells to the west and north of the plume to acquire screening data on geologic factors which
influence the recovery and mobilization of the groundwater contaminant plume.

In addition, Kleinfelder recommends using bailers for the regular manual extraction of LNAPL in
monitoring wells MW-8, MW-17, and MW-12 due to the relatively rapid product recovery rate out of the
six (6) monitoring wells tested. Extraction using passive skimmers or pneumatic sippers was considered
for removal; however, manual LNAPL removal is projected to cost less due to the materials costs of
passive recovery systems.

Following DEQ’s review of this report, Kleinfelder recommends that a meeting be held to discuss the
findings and recommendations to finalize the path forward for this Site.

This report may be used only by the Client and the registered design professional in responsible charge
and only for the purposes stated for this specific engagement within a reasonable time from its
issuance, but in no event later than two (2) years from the date of the report.

The work performed was based on project information provided by Client. If Client does not retain
Kleinfelder to review any plans and specifications, including any revisions or modifications to the plans
and specifications, Kleinfelder assumes no responsibility for the suitability of our recommendations. In
addition, if there are any changes in the field to the plans and specifications, Client must obtain written
approval from Kleinfelder’s engineer that such changes do not affect our recommendations. Failure to
do so will vitiate Kleinfelder’s recommendations.”

Kleinfelder offers various levels of investigative and engineering services to suit the varying needs of
different clients. It should be recognized that definition and evaluation of geologic and environmental
conditions are a difficult and inexact science. Judgments leading to conclusions and recommendations
are generally made with incomplete knowledge of the subsurface conditions present due to the
limitations of data from field studies. Although risk can never be eliminated, more detailed and
extensive studies yield more information, which may help understand and manage the level of risk.
Since detailed study and analysis involves greater expense, our clients participate in determining levels
of service that provide adequate information for their purposes at acceptable levels of risk. More
extensive studies, including subsurface studies or field tests, should be performed to reduce
uncertainties.

ft = feet
ND = not detected
Dry = no groundwater was observed in monitoring well
NM = Not measured
NC = not calculated
amsl = above mean sea level
* = The hydrocarbon density of 0.8 gram/milliliter is used to correct groundwater elevations based on the
waste characterization result collected from MW-17 on March 12, 2023 and analyzed by Pace Analytical.
Groundwater elevations were corrected for the presence of Product using the formula:
(Top of Casing Elevation – Depth to water) + (Depth to water – Depth to Product) (Hydrocarbon Density* / Water
Density)

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

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
J The identification of the analyte is acceptable; the reported value is an estimate.
J2 Surrogate recovery limits have been exceeded; values are outside lower control limits.
J3 The associated batch QC was outside the established quality control range for precision.
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.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
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.

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.

Project Narrative
Due to the low flashpoint temperature of this sample, the lab determined that analyzing the sample in duplicate was not
advisable due to safety concerns.

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
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
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
The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG.
