EXECUTIVE SUMMARY
On behalf of Pilot Flying J (Pilot), Apex Companies, LLC (Apex) has completed
groundwater monitoring activities associated with the soil and groundwater remediation system
located at the Pilot Travel Center #56, a retail gasoline station. In accordance with North
Carolina Department of Environmental Quality (NC DEQ) regulatory reporting requirements,
Apex has prepared a Corrective Action Monitoring Report for the subject property located at
2825 Lane Street in Kannapolis, North Carolina. This report includes results of the semi-annual
groundwater sampling for the period beginning July 1, 2019 and ending December 31, 2019.
The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984
and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company.
In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs
obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975.
It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001,
when Pilot Travel Centers, LLC purchased the property.
The objective of the Corrective Action Plan (CAP) prepared by Apex, was to maintain
groundwater quality conditions at the site below the applicable 2L Standards for benzene and
meth tertbutyl ether (MTBE) while aggressively remediating source area groundwater and minor
soil contamination. The corrective action approach to achieve the aforementioned goals for
groundwater at the site consisted of an engineered air sparging and soil vapor extraction (SVE)
system coupled with monitored natural attenuation. Air sparging will be effective to remove the
volatile hydrocarbon constituents, including MTBE from the groundwater. SVE will capture
volatile organic vapors from the subsurface and provide an increased pressure gradient to
enhance the efficacy of the air sparging. The end of active remediation will be determined when
asymptotic conditions are reached in dissolved hydrocarbon concentrations in groundwater or
when the applicable 2L standards have been achieved, or risk can be reduced.
CAP implementation at the site began in April 2012. Prior to CAP implementation seven
monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were
above the benzene 2L limit of 1.0 micrograms per liter (µg/L). The MTBE 2L limit of 20 µg/L
was exceeded in eight monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23,
MW-24, and DMW-3) prior to CAP implementation.
At the conclusion of 4th Quarter 2019 CAP implementation there was no measurable free -
phase petroleum product at the site, monitoring well MW-23 exceeded the benzene 2L CAP
endpoint, and MW-9, MW-14, and MW-23 exceeded the MTBE 2L CAP endpoint. Analytical
results were consistent with previous sampling events. Petroleum compounds have never been
detected in any of the area potable water supplies and sentinel wells such as MW-21, MW-22,
and MW-25 continue to indicate that the gasoline plume is confined to the original source zone
identified and described in both the Comprehensive Site Assessment (CSA) and approved CAP.
Mass balance calculations indicate that the mass of MTBE and benzene remaining in the
aquifer are less than one -tenth gram in groundwater, down from less than one-half gram at the
CA Monitoring Report (July 1 to Dec. 31, 2019) iii January 27, 2020

Incident#36096

conclusion of 2nd Quarter 20119 monitoring. Apex recommends initiating post -CAP monitoring
of the site for the following reasons:
• Mass balance calculations of remaining benzene and MTBE at the site show less
than one -tenth gram of combined MTBE and benzene remain onsite as a result of
the incident. Additionally, a mass reduction for MTBE and benzene of 99.9% has
been accomplished with the remediation system.
• Absence of measurable dissolved -phase petroleum compounds in area water
supply wells since source identification in June 2006.
• Absence of measurable dissolved -phase petroleum concentrations in sentinel
wells, MW-21, MW-22, and MW-25.
• Direction of shallow groundwater flow to the North -Northwest, which is cross -
gradient from potable water supplies.
• Presence of municipally supplied potable water to many of the area businesses
and residences.
Apex recommends continued system deactivation and an additional groundwater
monitoring event in June 2020 to observe a full year of dissolved -phase trends in groundwater
after system activation. Based on June 2020 dissolved -phase analytical results, Apex will make
recommendations regarding system reactivation, additional groundwater monitoring events,
potential modeling options to remove risk from the area potable supply wells, and/or additional
sentinel monitoring wells between the site and potable water supply wells to reduce risk.

1.0 INTRODUCTION
On behalf of Pilot Flying J (Pilot), Apex Companies, LLC (Apex) has completed semi-
annual groundwater monitoring activities associated with the soil and groundwater remediation
system located at the Pilot Travel Center #56, a retail gasoline station. In accordance with North
Carolina Department of Environmental Quality (NC DEQ) regulatory reporting requirements,
Apex has prepared a Corrective Action Monitoring Report for the subject property located at
2825 Lane Street in Kannapolis, North Carolina (Figure 1). This report includes semi-annual
groundwater sampling for the period beginning July 1, 2019 and ending December 31, 2019.
The remediation system was installed by Apex in accordance with the NC DEQ-approved
Corrective Action Plan (CAP) to address the multiple -phase contaminants identified on the
subject property. A description of the remediation system design and function is presented in
Section 2.0. A site plan depicting pertinent features of the subject site and surrounding area is
provided as Figure 2. This report for semi-annual groundwater monitoring at the Pilot #56
facility is being submitted to Ms. Trudy Beverly of NC DEQ, on behalf of Pilot.
2.0 SITE HISTORY AND BACKGROUND
The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984
and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company.
In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs
obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975.
It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001,
when Pilot Travel Centers, LLC purchased the property.
According to records reviewed by Apex, seven underground storage tanks (USTs) were
closed by removal in May 1994. The UST Closure Report also documented that two 12,000-
gallon USTs were removed from service in 1991. A list of current and historical USTs for the
site are provided in Table 1. The report also documented that there were releases associated with
both product lines and the southern UST tank basin. The release was assigned incident number
6379 by the North Carolina Department of Environment and Natural Resources (NCDENR).
The site was redeveloped and subjected to active remediation. Following 18 months of active
remediation, the incident was closed by NCDENR in 1998. Historical release information is
provided in Table 2.
In April 2006, a contractor mobilized to the site to gauge monitoring wells prior to
abandonment on behalf of the responsible party for incident 6379. The contractor reportedly
discovered light non -aqueous phase liquid (LNAPL) in RW-8 and MW-9. Follow-up
investigation in the tank areas and product lines failed to determine a new source. NCDENR
considered the LNAPL to be a new release and assigned incident number 36096.
Several phases of assessment have occurred since 2006. A site check on the south side of
the facility was performed which focused on soils around the new UST basin and the dispenser
lines. A total of 22 soil samples were collected for total petroleum hydrocarbons (TPH)
gasoline -range organics (GRO) analysis. Nine of the 22 soil samples were analyzed for TPH
CA Monitoring Report (July 1 to Dec. 31, 2019) 1 January 27, 2020

Incident#36096

diesel -range organics (DRO) as well. Four soil samples were reported with GRO concentrations
above the NCDENR UST action level of 10 milligrams per kilogram (mg/kg) at the time of the
investigation. DRO were detected in five of the soil samples above 10 mg/kg. A Phase II
Limited Site Assessment was conducted and submitted, and the site was assigned a "High Risk"
ranking by NCDENR. On February 20, 2009, NCDENR issued a Notice of Regulatory
Requirements requesting a Comprehensive Site Assessment (CSA) for the site.
A CSA was prepared for the site in December 2009 that delineated the dissolved -phase
groundwater concentrations vertically and horizontally. An additional round of sampling
conducted in September 2010 confirmed the previous delineation. The dissolved -phase
hydrocarbon plume did not extend beyond the site property line and the detected groundwater
analytes did not exceed the gross contaminant levels (GCLs). The site is ranked `high risk' due
to the presence of water supply wells located within a 1,000-foot radius of the source area. It is
important to note that all the identified supply wells are located hydraulically cross -gradient of
the site and over 425 feet from any exceedances of the North Carolina 15A NCAC 2L
groundwater standards (2L). Repeated sampling and analysis of the water supply wells have
never detected petroleum hydrocarbons in the samples collected since identification of the
release in June 2006. Potable water supply well locations and other receptors are identified on
Figure 3 corresponding to property owners, land use classifications, and other receptors as
documented in Tables 3, 4, and 5, respectively. Furthermore, sentinel wells such as MW-21,
MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original
source zone identified and described in both the CSA and approved CAP. Monitoring well
locations are depicted on Figure 4. Municipally supplied potable water is available to area
residents for connection.
Silty sands dominate the lithology at the site. Shallow soil on site is disturbed and very
heavily compacted. Bedrock was encountered at approximately 45 ft below land surface (bls) at
DMW-2. Shallow groundwater is encountered at approximately 22 ft bls in the developed
portion of the site and flows to the north-northwest. Geologic cross -sections prepared during
CAP development are included as Appendix A.
The product of concern is unleaded gasoline. The two primary analytes of concern are
meth tertbutyl ether (MTBE) and benzene. Historically there were other exceedances of the 2L
standard, but there were no 2L exceedances in wells without having either benzene or MTBE
present above 2L standards. The source area was presumed as south of the building, near MW-
24. At the time of CAP development, the assumed dissolved -phase groundwater contaminant
plume across the site was approximately 180 feet long by 90 feet wide and 30 feet deep. Mass
balance calculations indicated that the MTBE mass in the aquifer prior to active remediation was
approximately 124 grams in groundwater.
Based on the risk ranking for the site, corrective action objectives (CAOs) listed below
were established for each site media by NCDENR. The status of the site in achieving the
established CAOs are also noted. According to the North Carolina Administrative Code,
(NCAC) 15A 2L .0407 soil must be cleaned up to Maximum Soil Contaminant Concentrations
(MSCCs) for soil to groundwater or residential standards, whichever is lower. As documented in
the approved CAP, the CAOs for residential soil were achieved prior to CAP
CA Monitoring Report (July 1 to Dec. 31, 2019) 2 January 27, 2020

Incident#36096

implementation. The remediation design in the CAP addressed the nominal soil impact in the
southern area subsurface that remained above soil -to -groundwater standards. According to
NCAC 15A 2L .0202, surface water must be remediated to NCAC, 15A 2B standards (2B). The
2B standard for benzene was 70 µg/L. As documented in the approved CAP, the CAOs for
surface water at the site were achieved prior to CAP implementation as no measurable
surface water impact has been detected at the site. As such, remedial measures for stormwater
and surface water treatment were not carried forward in the CAP. According to NCAC 15A 2L
.0202, groundwater at the site must be remediated to the applicable 2L Standards which are 1.0
µg/L and 20 µg/L for benzene and MTBE, respectively.
The objective of the CAP was to maintain groundwater quality conditions at the site
below the applicable 2L Standards for benzene and MTBE while aggressively remediating
source area groundwater and minor soil impact. The corrective action approach to achieve the
aforementioned goals for groundwater at the site consisted of an engineered air sparging and soil
vapor extraction (SVE) system coupled with monitored natural attenuation. Air sparging will be
effective to remove the volatile hydrocarbon constituents, including MTBE from the
groundwater. SVE will capture volatile organic vapors from the subsurface and provide an
increased pressure gradient to enhance the efficacy of the air sparging. The end of active
remediation will be determined when asymptotic conditions are reached in dissolved
hydrocarbon concentrations in groundwater or when the applicable 2L standards have been
achieved, or risk can be reduced. A full description of the remediation system is provided below
in Section 3.0.
CAP implementation at the site began in April 2012. Prior to CAP implementation seven
monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were
above the benzene 2L limit of 1.0 µg/L. The MTBE 2L limit of 20 µg/L was exceeded in eight
monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23, MW-24, and DMW-3)
prior to CAP implementation. On December 12, 2017 Apex met with Department of
Transportation (DOT) staff and their consultant to inspect monitoring wells that were proposed
for abandonment during a road construction project at the site. As a result of the construction
project Apex turned off AS-5 supplying air to MW-18 pending abandonment by others.
Additional wells requiring abandonment for the construction project were MW-3 and MW-19.
At the conclusion of 2nd Quarter 2019 CAP implementation the dissolved -phase endpoint for
benzene of 1.0 µg/L was exceeded in monitoring well MW-23. The dissolved -phase endpoint
for MTBE of 20 µg/L was exceeded in monitoring wells MW-14, MW-17 and MW-23. Based
on 2nd Quarter 2019 analytical results of an average MTBE concentration across the site of 80.2
µg/L and an average benzene concentration of 0.57 µg/L, mass balance calculations indicate the
mass of MTBE and benzene remaining in the aquifer are less than one half gram.
3.0 REMEDIATION SYSTEM
The SVE and air sparge remediation system at the Pilot #56 facility was successfully
activated on April 18, 2012. The SVE system consists of a Roots Universal RAI® 36 blower
(replaced February 2017) paired with a ten horsepower Baldor Electric motor. Together the
system module is capable of a maximum extraction rate of 195 actual cubic feet per minute
CA Monitoring Report (July 1 to Dec. 31, 2019) 3 January 27, 2020

Incident#36096

(ACFM) at a vacuum of 12.0 inches of mercury (in Hg). The air sparge system consists of a 15
horsepower "rotary screw" compressor capable of 44-cubic feet per minute (CFM) at 55.0
pounds per square inch (PSI). The complete system is housed in a mobile eight foot by 16 foot
enclosed cargo trailer. The SVE manifold contains three "legs" capable of supplying a vacuum
at recovery locations SVE-1 through SVE-3. The remediation system layout with SVE well
locations is depicted on Figure 5. An air sparge manifold within the remediation system
enclosure includes individual gate valves, pressure gauges, pressure regulators, flow meters, and
check valves required to properly regulate air flow to allow for optimum treatment of the
identified subsurface petroleum constituents at air sparge points AS-1 through AS-16.
Activation activities included transportation of the turn -key system to the site and connection to
the sub -gradient infrastructure and separately metered power from other site activities. The
remediation system layout with air sparge well locations is depicted on Figure 6. In response to
NC DEQ directives dated August 8, 2019, the SVE and air sparge system components were
deactivated on August 14, 2019.
4.0 GROUNDWATER MONITORING
During this phase, Apex performed a semi-annual groundwater monitoring event to
assess water table elevations and current dissolved -phase contaminant levels. Pursuant to the NC
DEQ-approved CAP, Apex performed monitoring and sampling at monitoring wells MW-9,
MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and
DMW-3. On December 19, 2019, Apex used a SolinstTM electronic interface probe to
investigate for the presence of free product and to measure groundwater elevations. Free product
was not detected in any of the groundwater monitoring wells gauged during this phase.
Groundwater elevation data for the gauging event is presented in Table 6. Groundwater flow at
the site was determined by the triangulation method of the relative groundwater elevations within
the twelve monitoring wells. Figure 7 is a water table gradient map generated from the relative
elevations of equilibrated groundwater as measured on December 19, 2019. Relative
groundwater elevations based on surveyed top of casing elevations predict shallow groundwater
flow is to the north-northwest, which is consistent with previous investigations.
Monitoring/recovery/air sparge well locations are depicted on Figures 4, 5, and 6. Shallow
groundwater flow direction is depicted on Figures 1, 3, and 7.
Per NC DEQ directives, on December 19, 2019, Apex collected groundwater samples
from twelve monitoring wells (MW-9, MW-11, MW-12, MW-14, MW-17, MW-20, MW-21,
MW-22, MW-23, MW-24, MW-25, and DMW-3). Prior to sampling, Apex purged each well to
remove suspended sediment from the water column and to collect samples representative of
aquifer conditions. Each well was purged until a minimum of three well volumes had been
displaced. Groundwater samples were collected using dedicated, disposable, high -density
polyethylene bailers and were transferred directly into the appropriate sample containers
immediately upon collection. The samples were stored on ice pending delivery to the laboratory.
Disposable, latex gloves were used during all phases of sample collection. Groundwater samples
were submitted to Pace National (Pace) in Mount Juliet, Tennessee for volatile organic
compound (VOC) analysis via U.S. EPA SW-846 method 6200B. Strict sample security and
chain -of -custody documentation were maintained during all phases of transport. Analytical

results yielded petroleum compounds in five of the twelve monitoring wells sampled, with
maximum benzene and MTBE concentrations of 1.99 µg/L and 115 µg/L, respectively in
monitoring wells MW-23 and MW-9. A summary of current groundwater quality data is
presented in Table 7. Chain -of -custody documentation and the laboratory Certificates of
Analyses are included as Appendix B. Historical groundwater analytical results are provided in
Appendix C. The dissolved -phase endpoint for benzene of 1.0 µg/L was exceeded in monitoring
well MW-23. The dissolved -phase endpoint for MTBE of 20 µg/L was exceeded in monitoring
wells MW-9, MW-14 and MW-23. Analytical results were consistent with previous sampling
events. An isoconcentration map for MTBE is provided as Figure 8. Trend graphs depicting
benzene and MTBE concentrations over time as compared to CAP endpoints are provided as
Appendix D.
Per NC DEQ directives, on December 19, 2019, Apex also collected groundwater
samples from six supply wells (5922, 5925, 5927, 5955 Turkey Road and 2847 and 2865 Lane
Street). Supply well locations are depicted on Figure 3. A list of property owners for the supply
wells and land use classifications are provided as Tables 3 and 4, respectively. The supply well
samples were collected from outdoor spigots after being purged for approximately ten minutes.
Clean, disposable latex gloves were used during all phases of sample collection. The samples
were labeled and stored on ice pending delivery to the laboratory. Supply well samples were
submitted to Pace for VOC analysis via U.S. EPA SW-846 method 6200B. Strict sample
security and chain -of -custody documentation were maintained during all phases of transport.
Petroleum constituents were not detected in any of the supply well samples; however,
tetrachloroethene at a concentration of 2.18 µg/L was detected in supply well SW-5922, which
was consistent with the previous sampling events. Tetrachloroethene is typically associated with
the use of solvents and could be the result of some recent plumbing repairs at the residence. The
laboratory Certificate of Analysis and chain -of -custody records are provided as Appendix B.
The site is ranked `high risk' due to the presence of water supply wells located within a
1,000-foot radius of the source area. It is important to note that all the identified supply wells are
located hydraulically cross -gradient of the site (shallow groundwater flow is to the
North/Northwest) and over 425 feet from any exceedances of the North Carolina 15A NCAC 2L
groundwater standards (2L). Repeated sampling and analysis of the water supply wells have
never detected petroleum hydrocarbons in the samples collected since identification of the
release in June 2006. Furthermore, sentinel wells such as MW-21, MW-22, and MW-25
continue to indicate that the gasoline plume is confined to the original source zone identified and
described in both the CSA and approved CAP.
5.0 CORRECTIVE ACTION MONITORING REPORT SUMMARY
Apex has completed CAP monitoring activities associated with the Pilot #56 facility
located in Kannapolis, North Carolina for the period beginning July 1, 2019 and ending
December 31, 2019. At the conclusion of 4th Quarter 2019 CAP implementation monitoring well
MW-23 exceeded the benzene 2L CAP endpoint and MW-9, MW-14, and MW-23 exceeded the
MTBE 2L CAP endpoint. Analytical results were consistent with previous sampling events.
Petroleum compounds have never been detected in any of the area potable water supplies and

sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume
is confined to the original source zone identified and described in both the CSA and approved
CAP.
Mass balance calculations presented in the CAP Performance Report dated January 27,
2020 indicated that the mass of MTBE and benzene remaining in the aquifer are less than one -
tenth gram in groundwater, down from less than one-half gram at the conclusion of 2nd Quarter
2019 monitoring. Apex recommends initiating post -CAP monitoring of the site for the following
10?3.Y1I113
• Mass balance calculations of remaining benzene and MTBE at the site show less
than one -tenth gram of combined MTBE and benzene remain onsite as a result of
the incident. Additionally, a mass reduction for MTBE and benzene of 99.9% has
been accomplished with the remediation system.
• Absence of measurable dissolved -phase petroleum compounds in area water
supply wells since source identification in June 2006.
• Absence of measurable dissolved -phase petroleum concentrations in sentinel
wells, MW-21, MW-22, and MW-25.
• Direction of shallow groundwater flow to the North -Northwest, which is cross -
gradient from potable water supplies.
• Presence of municipally supplied potable water to many of the area businesses
and residences.
Apex recommends continued system deactivation and an additional groundwater
monitoring event in June 2020 to observe a full year of dissolved -phase trends in groundwater
after system activation. Based on June 2020 dissolved -phase analytical results, Apex will make
recommendations regarding system reactivation, additional groundwater monitoring events,
potential modeling options to remove risk from the area potable supply wells, and/or additional
sentinel monitoring wells between the site and potable water supply wells to reduce risk. This
report, prepared in accordance with NC DEQ-approved scope of work, is being submitted to Ms.
Trudy Beverly of NC DEQ on behalf of Pilot.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
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
ONE LAB. NATIONWIDE.
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
CP
IP
FTC
FSS
MDL
Method Detection Limit.
ND
Not detected at the Reporting Limit (or MDL where applicable).
[Cn]
RDL
Reported Detection Limit.
Rec.
Recovery.
FSr
RPD
Relative Percent Difference.
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
6
QC
(S)
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.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
a
Dilution
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.
FSC
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
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.
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"
Result
(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.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
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
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
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.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
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.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
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.
