1. BACKGROUND AND PURPOSE
WithersRavenel (WR) performed a Receptor Survey for the ±5.32-acre site located at 1009 Forestville Road,
Wake Forest, Wake County, North Carolina (Figure 1). According to Wake County GIS records, the subject
property consists of the following parcel:
1749680479 1 Sassom, LLC 1 1009 Forestville Road 1 ±5.32
Historically, a farm operated at the property and made use of two unregistered commercial underground
storage tanks (USTs), one containing diesel and one containing gasoline, that were removed in 2005. After
removal of the USTs, soil samples revealed concentrations of petroleum -related contaminants in excess of
NCDEQ action levels and groundwater samples revealed concentrations of petroleum -related contaminants
exceeding the North Carolina 15A NCAC 2L .0202 Groundwater Quality Standards at monitoring wells MW-
1 and MW-2. The onsite water supply well was sampled in August 2015, and the results of the sampling
event showed no volatile organic compounds (VOCs) at concentrations above laboratory reporting limits in
water from the well on that date.
One vacant, single-family, brick, ranch house is present on the property, which is 2,326 sq. feet in area and
was built in 1957, according to Wake County iMAPS website. The former storage building to its southeast
is no longer present. One of the monitoring wells installed in one of the former UST basins has been
destroyed, and the water supply well is in the far southeast corner of the property. The water supply well
is currently not in use, but is considered active. The property is surrounded by new commercial and
residential developments, as well as Heritage High School.
Sassom, LLC received a Letter of Eligibility to enter the Brownfields Program on August 21, 2018.
After the meeting held on October 9, 2018 with the representatives of Sassom, WR and NCDEQ
Brownfields Program, several issues that require additional investigation per the Program were identified.
These issues involve areas where additional contamination may be present. Those areas are described
below:
1) Groundwater upgradient and downgradient of the known groundwater contamination in the
source area of the former USTs;
2) Soils surrounding or beneath the former two USTs which were not over -excavated at the time
of UST removal;
3) Soil vapor in areas under proposed building footprints in the vicinity of the former USTs.
Specific areas of the property which will be developed into parking areas or building (retail space and
restaurants) and therefore will be investigated include the following:
A 3,000-gallon diesel fuel underground storage tank (UST) was removed from the site in March
2005. No over -excavation was conducted. The final excavation measured approximately 15.5 feet
x 22 feet x 12.5 feet deep, according to the UST Closure Report, dated July 8, 2005. Product lines
and dispensers were located immediately above the UST and were removed during the excavation.
The dimensions of the diesel UST were 8 feet x 14 feet. Upon removal, the UST was observed to
be coated and in good condition. One monitoring well (MW-2) was installed on the north side of
the tank pit in July 2007, as part of the Limited Site Assessment conducted per NCDEQ UST section
requirements.

A 2,000-gallon gasoline fuel UST was removed from the site in March 2005. No over -excavation
was conducted. The final excavation measured approximately 11 feet x 23 feet x 10.5 feet deep,
according to the UST Closure Report, dated July 8, 2005. The UST dimensions were 5 feet x 17 feet.
Upon removal, minor holes were noted along the bottom of the UST and it displayed rusting and
pitting. One monitoring well (MW-1) was installed within the tank pit in July 2007 as part of the
Limited Site Assessment.
In January 2019, WR conducted soil sampling in the locations of the two former USTs on site to delineate
the extent of petroleum in the surrounding soils, and WR installed three new monitoring wells. Groundwater
was collected from the existing monitoring well MW-1, along with samples from the three new onsite
monitoring wells. The results of the soil and groundwater analyses have been submitted to the Brownfields
Program. Monitoring well MW-2 had been destroyed, and was properly abandoned by a licensed driller.
A receptor survey was conducted in January 2019, the results of which are included in Figure 2 and
Appendix A. Figure 2 includes a site map of the subject property with nearby surface waters and three
known water supply wells in the vicinity.
In October 2019, WR conducted soil vapor sampling at nine locations that will be under proposed building
footprints, according to the current site commercial plan. Figure 3 includes the commercial plan with all
sampling locations mapped.
WR has prepared this report to document the sample locations, sample acquisition details, and sample
analysis results from the January 2019 soil and groundwater investigation as well as the October 2019 vapor
intrusion investigation. This report includes soil, groundwater and soil vapor sampling data and laboratory
analytical reports for the analyses described in the Brownfields Assessment Workplan dated January 7, 2019
for soil and groundwater sampling, and the Brownfields Assessment Workplan dated October 2, 2019 for
soil vapor sampling (workplans). This report also discusses the comparisons of the analytical results to the
appropriate NCDEQ standards, screening levels and preliminary soil remediation goals, and the potential
implications with regard to the need for further action.
2. SOIL SAMPLING AND ANALYTICAL RES ULTS
On January 9, 2019, WR mobilized to the subject property with Quantex, Inc. (sub -contractor driller) to
advance soil borings around the former UST areas to determine the extent of petroleum -impacted soils at
the locations illustrated on Figure 3.
The known depth of grade at the site is not yet known for the development of the property. Therefore, WR
screened and collected soil samples at approximately 5 feet below ground surface (bgs) from eight locations;
four locations surrounding each tank pit. The samples were labeled as T1(UST Tank 1) SW1-SW4 (Sidewalls
1-4) and T2 (UST Tank 2) SW1-SW4 and their locations are shown on Figure 3. Off -set borings were installed
to define the lateral extent of soil contamination; these included T1SW2-2, T1SW3-1 through T1SW3-5,
and T1SW4-2. These locations are where previous investigation had not been conducted, as the tanks were
removed but no over -excavation was conducted, and which may be disturbed by planned future
redevelopment activities. Historical investigation groundwater results indicate that contaminants may be
present at these locations. Boring logs are included in Appendix B.
WR also collected soil samples at the locations where monitoring wells were installed. Soils were screened
with a PID and collected at a depth of 5 feet bgs, to compare to results from the two tank pit areas, T1 and
T2. The samples were collected using a new, dedicated macrocore liner in accordance with the procedures
provided in the January 7, 2019 workplan.

1. Our People. Your Success.
The samples were screened with a Photoionization Detector (PID) and collected using a new, dedicated
macrocore liner and placed in laboratory prepared containers. The samples were submitted to a NC certified
laboratory under standard Chain -of -Custody procedures for analysis of the following:
• Volatile organic compounds (VOCs) by EPA Method 8260B
• Semi-VOCs (SVOCs) by EPA Method 8270D, and
• RCRA Metals by EPA Methods 6010 and 7470.
Analytical results indicated that there were no detected petroleum -related compounds in the soil
surrounding former Tank 2, but some petroleum -related compounds were detected in the soils surrounding
former Tank 1. The horizontal extent of petroleum -contaminated soil is generally defined as extending to
the east and south of the former Tank 1 location. Table 1 and Figure 4 show the analytical results of the soil
sampling at the extent of the petroleum footprint. Samples were collected from the depth of each boring
with the highest VOC reading on the PID during sampling activities. Field notes are included in Appendix C,
and laboratory analytical reports are included in Appendix D.
3. GROUNDWATER SAMPLING AND ANALYTICAL RESULTS
On January 8, 2019, WR installed three additional groundwater monitoring wells on the site (MW-3, MW-
4, and MW-5) in the locations indicated in Figure 3. The locations and relative elevations of the monitoring
wells were surveyed in order to determine groundwater elevations and flow direction on site. The
monitoring wells were installed at these locations to determine whether petroleum -contaminated
groundwater on site is migrating to the south and east, which is the inferred direction of groundwater flow
from the source area in the vicinity of monitoring well MW-1, based on topography and surficial drainage
patterns at the site. Monitoring well MW-5 was intended to be indicative of background conditions. While
onsite, WR discovered what appeared to be the destroyed remains of former monitoring well MW-2. On
January 9, 2019, WR properly abandoned MW-2 according to 15A NCAC 02C rules.
Each boring was logged in the field. Boring log information includes but is not limited to; detailed soil
description and lithology at depths, depth of groundwater observed during drilling, notable reaction of drill
rig during advancement, depth of competent rock encountered, detailed notes/remarks, and a well
construction diagram. Boring log and monitoring well construction information is available in Appendix B.
After the Brownfields Program approved the three proposed locations, the monitoring wells were installed
by a NC Certified Well Contractor. A permanent 2-inch diameter groundwater monitoring well was installed
in each boring. Hollow stem augers were utilized to advance the borings. Well installation was done in
compliance with the most current 15A NCAC 2C well construction standards, and the wells are equipped
with locking aboveground protective covers.
WR determined the relative top of casing elevations for the one existing monitoring well and three newly -
installed monitoring wells so that the direction of groundwater flow from the source area could be evaluated.
Well construction details including installation date, top of casing elevations, ground surface elevations, total
well depths, well screen intervals, depths to groundwater, and groundwater elevations are summarized in
Table 2.
WR used an electronic water level indicator to record static water level measurements in the wells to
determine the static groundwater elevation in the well. Figure 5 shows groundwater elevation contours and
flow directions as well as land surface topography, surface water features, and monitoring well locations.
The groundwater elevation data collected in January 2019 imply that surficial groundwater flow is toward
the northwest across the site; not to the southeast as was previously inferred from topography and drainage
features shown on Figures 1 and 2.

1. Our People. Your Success.
On January 10, 2019, WR collected groundwater samples from existing monitoring well MW-1 and the
three newly installed monitoring wells (MW-3, MW-4 and MW-5). After the static water level was recorded,
the wells were purged and water quality parameters including pH, temperature, specific conductance and
turbidity were monitored until stabile in accordance with criteria described in the January 7, 2019 workplan.
Groundwater samples were then obtained by the low flow method described in that workplan. Copies of
the groundwater sampling forms that document the purging and sampling activities are included in Appendix
C.
The samples were submitted to a NC certified laboratory under standard Chain -of -Custody procedures for
analysis of the following:
VOCs by EPA Test Method 8260B; and
SVOCs by EPA Test Method 8270D.
Groundwater sample results were compared to the North Carolina Groundwater Quality Standards as listed
in 15A NCAC 2L .0202 (2L Standards).
Analytical results indicated that petroleum compounds are present in the groundwater at the former Tank
1 location, which includes monitoring well MW-1. Several petroleum -related compounds were identified in
the groundwater sample from monitoring well MW-1 at concentrations exceeding their respective 2L
Standards and above the Non -Residential VI GWSLs. Petroleum -related compounds were not detected in
the groundwater samples from the remaining monitoring wells MW-3, MW-4, and MW-5. The analytical
results are summarized in Table 3, and on Figure 6, and the full laboratory report is provided in Appendix
D.
4. TICAL RESULTS
On October 9, 2019 and under the direction of WR, SAEDACCO (sub -contractor driller) advanced nine soil
borings on the Wheat Fields Development property for the purpose of constructing temporary soil vapor
probes at locations SV-1 through SV-9 (see Figure 3). Each soil vapor probe boring was advanced to a
depth of five feet below the ground surface. The borings were advanced using Direct Push Technology,
and new Teflon tubing, fittings and sealants were used in the construction of each probe. The probes
were installed in accordance with the procedures described in the October 2, 2019 workplan. Each soil
gas probe was capped following installation, and allowed to equilibrate for at least 2 hours before
sampling. Soil vapor probe construction records are provided in Appendix B.
On October 10, 2019, the nine probes were leak tested using the helium shroud method for quality
control purposes, and then sampled using one -liter summa canisters in accordance with the procedures
provided in the October 2, 2019 workplan. One duplicate sample was collected. Photographs of each soil
vapor probe are included in Appendix C. Helium concentration measurements at the start and end of
each leak check, along with the helium concentration for each of the three purge volumes are recorded on
the field log book pages for October 10, 2019 contained in Appendix C.
The summa canisters were not be allowed to reach 0" Hg vacuum and they were closed when the
remaining vacuum pressure within the canister was approximately 5" Hg. The field log pages containing
the initial and final vacuums are included in Appendix C. The laboratory also recorded the remaining
vacuum pressure within the summa canisters upon receipt (see laboratory reports in Appendix D).
The soil vapor samples were submitted to a NC Certified Laboratory for analysis of VOCs by EPA Method
TO-15. The purpose of collecting and testing the soil vapor samples was to determine if past leaking
USTs have adversely affected soil vapor at locations beneath the proposed building foundations.
Concentrations of individual VOCs that were detected within the soil vapor samples obtained from the
site were compared to the most current version of the NCDEQ Division of Waste Management (DWM)

Hazardous Sites Branch Vapor Intrusion Screening Levels. Detectable concentrations of petroleum -related
compounds were identified in all of the soil vapor samples and the duplicate sample collected on October
10, 2019. However, none of the reported concentrations exceeded the February 2018 NCDEQ DWM
Exterior Soil Gas Screening Levels (SGSLs) for residential or non-residential settings. Comparison of the VOC
concentrations identified within the soil vapor samples to the SGSLs is provided in Table 4, and Figure 7
shows the analytical results for each soil vapor sampling location.
5. CONCLUSIONS
WR prepared a risk calculation using the most recent NCDEQ risk calculator, and using the highest
concentration for each detected compound among all samples of soil, groundwater, and soil vapor to
generate a conservative risk value for the entire site. Appendix E includes the input data used and resulting
risk calculations. These are summarized below as shown on Output Form 1A.
For the Primary Calculators, the soil combined pathways did indicate an unacceptable risk to
residents, however, the pathways did not indicate unacceptable risk to non-residential workers or
construction workers. The carcinogenic risk and hazard indices for the groundwater combined pathways
were exceeded for potential residents and non-residential workers.
For the Vapor Intrusion Calculators, utilizing the highest concentrations of compounds detected within
the soil, groundwater, and soil vapor samples collected, the carcinogenic risk and hazard indices
determined for the groundwater -to -indoor -air pathway were exceeded for potential residents and non-
residential workers. The calculated carcinogenic risk and hazard indices for the soil -gas -to -indoor -air
pathway risk did not indicate unacceptable risk for potential residents or non-residential workers.
The Contaminant Migration Calculators did determine that the source soil and source groundwater
exceeded target POE concentrations for the Protection of Groundwater Use Pathway.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
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
FTChave
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
FSS
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
ONE LAB. NATIONWIDE.
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.
Abbreviations and Definitions
(dry)
Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL
Method Detection Limit.
ND
Not detected at the Reporting Limit (or MDL where applicable).
RDL
Reported Detection Limit.
RDL (dry)
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
(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
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.
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.
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.
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.
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.
JO
J0: Calibration verification outside of acceptance limits. Result is estimated.
J1
Surrogate recovery limits have been exceeded; values are outside upper control limits.
J4
The associated batch QC was outside the established quality control range for accuracy.
J7
Surrogate recovery cannot be used for control limit evaluation due to dilution.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
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
FTChave
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
FSS
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
ONE LAB. NATIONWIDE.
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.
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.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
(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
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.
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.
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.
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.

QC
FAI
FSC
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.
Qualifier
Description
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.
J6
The sample matrix interfered with the ability to make any accurate determination; spike value is low.

Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
J Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
L-01 Laboratory fortified blank /laboratory control sample recovery outside of control limits. Data validation is not
affected since all results are "not detected" for all samples in this batch for this compound and bias is on the high
side.
V-35 Initial calibration verification (ICV) did not meet method specifications and was biased on the high side for this
compound. Reported result is estimated.
V-36 Initial calibration verification (ICV) did not meet method specifications and was biased on the high side. Data
validation is not affected since sample result was "not detected" for this compound.
Z-01 Compound fails the method requirement of 70-130% recovery for the LCS. Is classified by the lab as a difficult
compound and passes the in house limits of 50-150%.
