1.0 INTRODUCTION
The subject site is the Speedway 8299 facility located at 291 NC Highway 42 East
in Clayton, Johnston County, North Carolina (Drawing 1.1). The site is currently in
use as a convenience store and retail petroleum dispensing facility and operates one
12,000-gallon gasoline UST, two 6,000-gallon gasoline USTs and one 10,000-gallon
diesel UST. The layout of the facility is shown on Drawing 1.2.
On August 8, 2016, gasoline was observed inside the containment sumps for both the
submersible turbine pump (STP) and the #1 and #2 dispensers associated with the
6,000-gallon regular unleaded gasoline UST (Drawing 1.2). Upon detection, the system
was immediately taken out of service until the source of the release (loose connection
of valve) could be repaired. A Phase I LSA was conducted at the site in September
2016. Free product was detected in one well (MW-1) and a subsequent AFVR event
was performed to recover free product from the water table. Based on the results of
the Phase I LSA, the release was classified as high risk with an RRA score of H-255-D
due to the presence of two confirmed water-supply wells located within 1,000 feet of the
source area of the release. Additional monitoring wells were installed in June 2017 and
an MMPE event to recover additional free product from the water table was conducted.
Following the completion of the initial MMPE, a CSA was conducted at the site. During
the completion of the CSA, six additional type II monitoring wells and one type III
deep well were installed on site. It was noted during the second phase of CSA drilling
completed in November 2018 that the free product thickness on site had increased
significantly in monitoring wells MW-1, MW-3, MW-5 and MW-6. Mid-Atlantic requested
a second MMPE event to be conducted while the CSA activities were completed. The
second MMPE event was completed using monitoring wells MW-1, MW-3, MW-5, and
MW-6 during the week of January 14 through January 18, 2019. Free product gauging
indicated that free product was still present in monitoring wells MW-1, MW-3, MW-5, and
MW-6. Consequently, consecutive 96-hour events were conducted during the weeks of
December 2 through December 6 and December 9 through December 13, 2019. Prior
to post MMPE groundwater sampling conducted on January 7, 2020, two additional type
II monitoring wells were installed on site. An additional MMPE event was conducted from
July 20 through July 24, 2020. Following the July 2020 MMPE event and subsequent
August 2020 groundwater sampling event, three additional type II monitoring wells were
installed to help define the groundwater plume to the Gross Contaminant Levels (GCLs).
Additional MMPE events were conducted from February 8, 2021 through February
12, 2021, August 30, 2021 through September 3, 2021, and March 21, 2022 through
March 25, 2022. This report documents the post MMPE groundwater sampling activities
conducted on April 13, 2022. Selected site historical information is provided in Appendix
A.
The opinions included herein are based on our experience and the information obtained
during the study. This report is based on limited observations made on the dates noted
using the procedures described herein. If additional information becomes available, we
request the opportunity to review the information, reassess the potential environmental
concerns and modify our conclusions and recommendations, if appropriate.
2.0 SITE HISTORY AND SOURCE CHARACTERIZATION

Speedway LLC is listed as the current owner/operator of the UST System.
2.3 Information on Source of Release
On August 5, 2016, gasoline was observed inside the containment sumps for both the
STP and the #1 and #2 dispensers associated with the 6,000-gallon regular unleaded
gasoline UST (Drawing 1.2). Upon detection, the system was immediately taken out of
service until the source of the release (loose connection of valve) could be repaired.
The approximate locations of the STP sump and dispenser sump where the fuel/water
mixtures were initially observed are shown on Drawing 1.2.
2.4 Regional Geology and Hydrogeology
According to the map titled Geology of North Carolina (1985), prepared by the North
Carolina Geological Survey Section of the NCDEQ, the subject site is located in the areas
known as the Yorktown Formation and the Duplin Formation. The Yorktown Formation is
comprised of fossiliferous clay with varying amounts of fine-grained sand which is bluish

gray in color, and shell material commonly concentrated in lenses which are located
mainly in the area north of the Neuse River. The Duplin Formation is comprised of shelly,
medium- to coarse-grained sand, sandy marl, and limestone which is bluish gray in color
and is located mainly in the area south of the Neuse River. Based on descriptions of
subsurface geology, the subject site is located in the Yorktown Formation.
The subject site is located in the Coastal Plain physiographic region. In the coastal
plain, an aquifer is typically composed of one to several layers of eastward thickening,
permeable sands or limestone split by discontinuous, clay-rich materials. Confining units,
consisting of clay-rich sediments, exist above and below an aquifer. These confining
units are more continuous clay layers and separate the aquifer. The surficial or
unconfined aquifer overlies all the confined aquifers in the coastal plain.

Receptor information for the site was previously documented in Mid-Atlantic’s Phase I
Limited Site Assessment dated December 6, 2016. A receptor survey update was not
conducted during this monitoring event. Please refer to previous reports for detailed
receptor information. As indicated, the site is currently classified as “high” risk due to the
presence of free product on the water table and two confirmed (and several other likely)
drinking water supply wells located within 1,000 feet of the source area of the release.

According to the USGS topographic quadrangle map of Clayton, North Carolina (Drawing
1.1), the nearest surface water body is an unnamed tributary to the Neuse River, located
approximately 1,400 feet northeast of the source area of the release.
4.0 FIELD ACTIVITIES
On April 13, 2022 Mid-Atlantic personnel mobilized to the site to conduct post MMPE
groundwater sampling, which included liquid level measurements. Refer to Mid-Atlantic's
Free Product Recovery Report dated June 8, 2022 for results of the MMPE event.
4.1 Monitoring Well Installation
One additional type II monitoring well was installed at the site to better define the
groundwater plume to the GCLs. On February 24, 2022, monitoring well MW-16 was
installed to a depth of 20 feet below land surface to the north of the convenience storebuilding. The location of the monitoring well is depicted on Drawing 1.2. Monitoring well
construction details are summarized in Table 4.1 and construction records and soil boring
logs are provided in Appendix B.
4.2 Liquid Level Measurements
Mid-Atlantic personnel collected depth to free product and/or depth to groundwater
measurements from site monitoring wells on April 13, 2022. Monitoring well construction
details are provided in Table 4.1. Liquid level measurements, along with historical
measurements, are summarized in Table 4.2. As indicated, monitoring wells MW-1,MW-3, MW-5, MW-6, MW-11, and MW-12 exhibited approximately 0.37, 0.05, 2.81, 0.25,
0.05, and 0.34 feet of free product, respectively. Free product was not detected in wells
MW-2, MW-4, MW-6D, MW-7 through MW-10, and MW-13 through MW-16. Liquid level
measurements for the April 13, 2022 gauging activities is illustrated on Drawing 4.1.
4.3 Monitoring Well Sample Collection
Mid-Atlantic personnel collected groundwater samples from the monitoring wells
MW-2, MW-4, MW-6D, MW-7 through MW-10, and MW-13 through MW-16 on April
13, 2022. Groundwater samples were not collected from monitoring wells containing
free product. Groundwater samples were collected using the procedures described in
Appendix C. Samples were shipped to Pace National Laboratory (Pace) in Mt. Juliet,
Tennessee and analyzed by the methods shown on the chain-of-custody record provided
in Appendix D.
4.4 Soil Vapor Sample Collection
In order to determine interior vapor conditions from petroleum groundwater impacts,
Mid-Atlantic collected two soil vapor samples (SSSG-1 and SSSG-2) from within the
convenience store building. Samples were collected on February 25, 2022 and the

sample locations are depicted on Drawing 1.2. Sampling methodology is provided in
the recent Soil Gas Sampling Results letter report dated May 3, 2022 and included
as Appendix E.
5.0 DISCUSSION OF SAMPLING RESULTS
5.1 Summary of Analytical Results
The laboratory analytical report and chain-of-custody record for groundwater samples
collected on April 13, 2022 are provided in Appendix D and the results of selected
target compounds are summarized in Table 5.1 and on Drawings 5.1 and 5.2. As
summarized, the groundwater samples collected from wells MW-7, MW-8, MW-10, and
MW-14 exhibited several contaminant concentrations above the NCGQS but below
the GCLs. Samples collected from monitoring wells MW-2 and MW-13 exhibited
concentrations of benzene above its GCL. Contaminants of concern were not detected in
the groundwater samples collected from wells MW-4, MW-6D, MW-9, and MW-16 above
the laboratory method detection limits.
5.2 Description of Current Plume Size and Location
Free Product
On March 21, 2022, gasoline free product was measured in monitoring wells MW-1,
MW-3, MW-5, MW-6, MW-11, MW-12 and MW-13 at a thickness of 6.38, 2.37, 3.15,
3.15, 0.59, 4.24, and 4.25 feet, respectively. Wells MW-1, MW-3, MW-5, MW-6, and
MW-11 have historically exhibited free product. Well MW-12 was installed in January
of 2020 and well MW-13 was installed in January of 2021. As such, free product was
detected in wells MW-12 and MW-13 for the third time since installation during the
start of the March 2022 MMPE event. During the April 2022 groundwater monitoring
event, free product measured in monitoring wells MW-1, MW-3, MW-5, MW-6, MW-11,
and MW-12 exhibited approximately 0.37, 0.05, 2.81, 0.25, 0.05, and 0.34 feet of free
product, respectively. No free product was observed in monitoring well MW-13 during the
April 2022 monitoring event. Based on the results illustrated by the free product gauging
activities, the thickness of the free product observed in monitoring wells MW-1, MW-3,
MW-5, MW-6, MW-11, MW-12, and MW-13 appears to have diminished since March 21,
2022.Overall, the free product plume appears to be expanding/migrating towards the
west and may now be underneath a portion of the convenience store building. Additional
information regarding free product recovery is provided in the recent Free Product
Recovery Report dated June 8, 2022.The free product plume appears to be delineated
within the existing monitoring well network as depicted on Drawing 5.3.

Groundwater
Isoconcentration maps for benzene and naphthalene for the April 13, 2022 groundwater
sampling event are provided as Drawings 5.1 and 5.2, respectively. The dissolved-phasegroundwater contaminant plume is not fully delineated to the extent of the NCGQS,.
With the migration of the free product plume towards the west and sampling results from
newly installed monitoring well MW-16, the plume appears to be delineated towards the
northwest (to the north of the convenience store).
5.3 Additional Monitoring Information
• Proximity of Plume to Nearest Receptor
Based on the results of the LSA receptor survey, there are two confirmed water-supply
wells within 1,000 feet of the source area of the release and three confirmed water-supply
wells within 1,500 feet of the source area of the release. The nearest potential receptor
is the Greer Water-Supply Well (109 Neuse Ridge Drive), located approximately 375 feet
northwest of the release. Please note that monitoring well MW-4 was installed between
the source area of the release and the off-site Greer Water-Supply Well.As indicated
in Section 5.1, contaminants of concern were not detected in the groundwater sample
collected from this well at concentrations exceeding the laboratory method detection
limits or the NCGQS. With the migration of the free product plume in a westerly direction,
this plume may now be partially underneath the convenience store building.
• Groundwater Flow Direction
Based on measurements collected on April 13, 2022, groundwater appears to be highest
at well MW-8 and flow towards the north and towards the west with a hydraulic gradient
(measured from MW-8 towards MW-2) of approximately 0.020 ft/ft. An Estimated Water
Table Contour Map is provided as Drawing 4.1 (Note: estimated water elevation levels
for wells MW-1, MW-3, MW-5, MW-6, MW-11, and MW-12 were not shown due to
the presence of free product). As shown on the drawings in Appendix A, historical
groundwater flow has varied between east, north, and west. Water level measurements
and groundwater elevation data, as well as historical measurements, are provided in
Table 4.2. The hydraulic gradient was calculated using the procedure discussed in
Appendix C.
5.4 Soil Vapor Sample Results
Contaminants of concern were detected in both soil vapor samples at concentrations
exceeding laboratory method detection limits. However, risk calculator results indicatethat the soil vapor beneath the convenience store building’s floor slab does not appear
to pose an unacceptable risk to the occupants of the building. Additional information is
summarized in the Soil Gas Sampling Results letter included as Appendix E.

6.0 FUTURE SITE REMEDIATION
According to the NCDEQ, the incident is currently ranked “high risk” due to the presence
of free product on the water table and two confirmed drinking water supply wells (and
likely several more) located within 1,000 feet of the source area of the release. The
nearest surface water body is an unnamed tributary to the Neuse River, located
approximately 1,400 feet northeast of the source area of the release.
Mid-Atlantic is moving the site towards a remedial active approach. Dual Phase
Extraction (DPE) is currently planned to be implemented at this site and is being
evaluated for the logistics/feasibility of implementation. Mid-Atlantic recommends
continuing to conduct 96-hour MMPE events for free product removal. The next event
should be conducted in September 2022 or earlier.
7.0 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS
Site activities included in this report are summarized as follows:
• Depth to groundwater and free product thickness were measured in site
monitoring wells; and
• Groundwater samples were collected from site monitoring wells that did not
contain a measurable amount of free product.
Based on the results of the April 13, 2022 sampling activities, Mid-Atlantic concludes the
following:
• Free product is present on the water table in thicknesses up to 2.81 feet and
appears to be migrating towards the west;
• With the migration of the free product plume towards the west, the plume now
appears to be partially under the convenience store building;
• The groundwater samples collected from the site exhibited concentrations above
the NCGQS and the GCLs;
• Sampling results for newly installed monitoring well MW-16, which is located to
the north of the convenience store building, indicate that the dissolved phase
contaminant plume does not extend to that portion of the subject site;
• The groundwater sample collected from well MW-4 (installed between the source
area of the release and the Greer Water-Supply Well) did not exhibit
contaminants concentrations above the NCGQS. In addition, contaminants of
Groundwater Monitoring Report
Speedway 8299
Clayton, North Carolina

Page 7
concern were not detected in the groundwater sample collected from MW-4 at
concentrations above the laboratory method detection limits;
• Groundwater appears to be highest at well MW-8 and flows towards the north
and west with a hydraulic gradient (measured from MW-8 towards MW-2) of
approximately 0.020 ft/ft; and
• Soil vapor sampling from February 2022 indicate that the soil vapor beneath the
convenience store building's floor slab does not pose an unacceptable risk to the
occupants of the building.
Based on the conclusions, Mid-Atlantic recommends the following:
• Continued periodic sampling (at least semi-annual) of the monitoring wells to
evaluate contaminant plume movement;
• Continue to move the site towards a remedial active approach. DPE is currently
planned to be implemented at this site;
• Conducting MMPE events for free product removal until the majority of freeproduct has been removed and/or a remedial approach can be implemented;
and,
• Submittal of this report to the NCDEQ for their review and comment.

APPENDIX C MID-ATLANTIC FIELD PROCEDURES
Groundwater Sampling Procedures
I. Sample Collection
A. Monitoring Wells
Prior to sample collection, each well is purged of three to five standing well volumes or to
dryness to remove stagnant water from the well and well bore in an effort to collect
samples that are representative of the water quality in the formation surrounding each
well. Purging is performed either with a new, polyethylene bailer dedicated to each well, or
with a decontaminated pump. Samples are retrieved from the monitoring well using the
dedicated bailer. New nylon string is used on each dedicated bailer, and new nitrile
sampling gloves are donned prior to purging and sampling of each well.
B. Geoprobe “Screen Point Sampler”
The screen point sampler is a “grab” sampling device that is driven into the saturated zone
and a surrounding metal sheath is retracted, exposing a screen. Groundwater entering the
screen is then drawn to land surface through disposable tubing that is placed through the
hollow push rods. The sample is collected from the tubing into the appropriate sampling
glassware.
C. Water-Supply Wells
Water samples are typically collected from the available spigot that is nearest to the well.
The water is allowed to run at a high flow from the spigot for approximately 10 to 15
minutes to allow the water in the delivery lines to be purged. The sample flow is then
reduced and the samples are collected directly into pre-labeled containers as described
below. New nitrile sampling gloves are donned prior to sampling of each well.
D. Treatment System Influent/Effluent
Samples are typically collected from the influent or effluent of pump-and-treat groundwater
remediation systems using designated sampling ports in the influent and effluent water
transport lines. The water is typically allowed to run for several seconds to clear potential
debris in the sampling port. The sample is then collected directly into sampling containers
as described below. New nitrile sampling gloves are donned prior to sample collection.
II. Preparation for Laboratory Analysis
Groundwater samples are decanted directly into laboratory-prepared, pre-labeled, sampling
containers, packed in ice, and shipped to a certified laboratory under chain-of-custody control.
Laboratory analyses performed on the samples are specified on the chain-of-custody.
Groundwater Flow Direction Determination Procedure
I. Well Casing Rim Elevation Determination
After well completion, a measuring point is marked on the rim of each well casing by field personnel. A survey level and stadia rod is used to determine the vertical elevation of the measuring point relative to a designated site benchmark. The elevations are determined to the
nearest 0.01 foot.
II. Depth-to-Groundwater Measurements Prior to collecting depth-to-water measurements, the field technician opens the locking well
plugs and allows the water table to “stabilize” within the well. The technician then uses an electronic water level indicator (or oil/water interface probe, if free product is present) to measure the depth-to-water from the measuring point on the casing rim to the nearest 0.01 foot. The measured depths-to-water are then subtracted from the casing elevations to
determine water level elevations relative to the benchmark.
III. Horizontal Flow Direction Determination
Horizontal groundwater flow direction in the surficial aquifer is determined by development of a water table contour map based upon water table elevation data obtained from site monitoring wells. The water levels measured in deep, Type III monitoring wells are not used in constructing the water table map. Mid-Atlantic uses Golden Software’s “Surfer” version 7.0 to generate the contours using the Kriging method. Alternatively, the water-table contour map
may be hand drawn by Mid-Atlantic staff and then digitized by AutoCAD software. Groundwater flow direction is determined by interpreting the contours. Groundwater will flow in the direction from higher elevation to lower elevation (perpendicular to the generated contours).
IV. Vertical Flow Direction Determination Groundwater exhibits both horizontal and vertical components of flow through an aquifer. The
hydraulic gradient is the difference in hydraulic head divided by the distance along the flow
path. The vertical gradient may be either up or down within the aquifer. The vertical gradient is calculated using measurements obtained from a “paired” shallow monitoring well and a deep, Type III monitoring well. The gradient is calculated by first
determining the difference in the static water level elevations at the well pair. Second, the relative elevation of the middle of the screened interval is determined for each well pair. Finally, the difference in the static water level elevations at each well pair is divided by the difference in the mid-screen elevations for the well pair. This value is arbitrarily assigned a positive value if the groundwater is moving vertically downward (recharge area) and a negative
value if the groundwater is moving vertically upward (discharge area). Groundwater will flow in the direction from higher elevation to lower elevation.
Hydraulic Gradient Determination Procedure
The hydraulic gradient, which is a measure of the “steepness” of the water table, is
determined by dividing the change in the elevation (in feet) of the water table over
the change in horizontal distance (in feet) between two measuring points. Typically,
the gradient is determined after the Water Table Elevation Contour Map is prepared.
Two wells are typically selected that, when a line is drawn between the wells, the
orientation of this line approximates the direction of groundwater flow. The greater
the horizontal distance between the lines, the more representative the hydraulic
gradient value will be for the site. If two wells are not arranged in line with
groundwater flow, the hydraulic gradient can be estimated by performing the same
calculation using the contours generated for the groundwater flow direction map. The
units for the hydraulic gradient are feet/feet.
The hydraulic gradient (measured from MW-8 to MW-2 on April 13, 2022) for the
subject site was determined as follows:
Gradient = dh/dl = (86.83 – 85.70) / 55 = 0.020 ft/ft
where:
dh = change in head (more specifically, water table elevation) in feet
dl = horizontal distance (in feet) between monitoring wells or other head
measurement points.

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.

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.
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”

APPENDIX E SOIL GAS SAMPLING TEST RESULTS LETTER REPORT
May 3, 2022
Mr. Chuck Chiara Speedway, LLC 500 Speedway Drive
Enon, OH 45323 Reference: SOIL GAS SAMPLING TEST RESULTS
SPEEDWAY 8299
291 NC HIGHWAY 42 EAST
CLAYTON, NORTH CAROLINA
INCIDENT NO.: 42007
FACILITY ID NO.: 0-036192
MID-ATLANTIC JOB NO.: R2826.15
Dear Mr. Chiara:
As requested, Mid-Atlantic has conducted sub-slab soil gas testing for the above-referenced site.
The procedures and results are outlined below.
VAPOR SAMPLING POINT INSTALLATION AND SAMPLING
On February 24, 2022, two drill holes (SSSG-1 and SSSG-2) were advanced in the floor of the supply
room (eastern side of the building) to support the installation of vapor sampling equipment at these
locations, shown on the attached drawing. The locations were chosen to provide sample collection
directly over the area where free product is likely to be present on the water table. New “Vapor
Pins™” were installed at each location. These pins consist of a brass barb fitting with a silicone
sleeve to create a seal with the concrete when inserted using an installation/extraction tool. Once
installed, samples were collected into a Tedlar bag and submitted to Pace National laboratory in Mt.
Juliet, Tennessee for BTEX analysis using Method 18. A photoionization detector (PID) was also
utilized to measure VOC concentrations in sub-slab vapor. Additional details regarding the
installation and sampling procedures are provided in Mid-Atlantic’s field notes in Attachment A.
INVESTIGATIVE RESULTS
PID readings for sample SSSG-1 (southern sample) and SSSG-2 (northern sample) were 7.6 ppm
and 3.4 ppm, respectively. The laboratory analytical report is provided in Attachment B and results
are summarized on the NCDEQ Risk Calculator, provided in Attachment C. [Note: the UST Section
currently does not have established standards for soil gas concentrations. Therefore, for this exercise
we have adopted the Superfund Section’s methodology for determining risk.] According to the Risk
Calculator calculations for the sample SSSG-2, two compounds (benzene and ethylbenzene)
exhibited Calculated Carcinogenic Risk concentrations exceeding their initial screening levels.
Soil Gas Sampling Results May 3, 2022
Speedway 8299 Page 2
Clayton, North Carolina
However, actual risk is based on a Cumulative Carcinogenic Risk of 10-4 and the Cumulative
Carcinogenic Risk for this sample is 6.6X10-6, which is a factor of two less than the acceptable risk
benchmark. Sample SSSG-1 did not exhibit target compounds at concentrations exceeding the
Calculated Carcinogenic Risk benchmark. Neither sample exhibited target compounds at
concentrations exceeding the Hazard Index (1.0), which is a summation of the Calculated Non-
Carcinogenic Hazard Quotient.
CONCLUSIONS
Based on the results of the sampling and comparison to DEQ risk benchmarks, the soil gas beneath the building’s floor slab does not appear to pose an unacceptable risk to the occupants of the building. If you have any questions, please feel free to contact us at (919) 250-9918. Sincerely,
MID-ATLANTIC ASSOCIATES, INC.

Notes : Meet with Gary and Trey at 815. Discuss plan and select sample locations. Storage room on eastern side of building
selected for sample locations since the room had exposed concrete floors. One permanent pin was set in the southern portion
of the room adjacent to an electrical panel (SSSG-1) and the other was set in the northern portion of the room adjacent to a
refrigerator (SSSG-2). Both pins were installed using a hammer drill. The upper approximately 2 inches of floor were drilled
using a 1.5-inch diameter spline bit. The remaining approximately 5 inches of floor were drilled using a 5/8-inch bit to a depth
beneath the floor. A brass pin was set in the hole and a cap and stainless steel cover were installed to protect the point. At
each point 240 mL of air were purged from the points using a 60 mL syringe. Following that, air samples were collected at
each point by purging 600 mL into a tedlar bag. The bags were placed into a cooler and later provided to a courier affiliated
with Pace National.
Following installation and sampling, the points were connected to a MiniRAE 3000 PID. The PID increased to a reading of 7.6
ppm at SSSG-1 and 3.4 ppm at SSSG-2. The cap and cover were set at both points once finished. Kim, the store manager,
looked in the storage room and not raise concerns about the sample locations (which were confirmed prior to installation) or
appearance of the points once installed.

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.
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.

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate carcinogenic
risk or hazard quotient. Lead concentrations are compared to the National Ambient Air Quality Standard of 0.15 μg/m3.
Carcinogenic risk and hazard quotient cells highlighted in orange are associated with non-volatile chemicals. Risks are calculated for these values if
indoor air concentrations are entered and indoor air screening levels have been established, but it should be noted that detections of these chemicals are
likely not associated with vapor intrusion.
