1.0 INTRODUCTION
In accordance with our Proposal and Standard Conditions for Engagement, EBI Consulting (EBI) is
pleased to submit our Phase II Environmental Site Assessment (ESA) Report (Report) on the property located
at 1514 Main Street, Ramseur, North Carolina (the Subject Property). Eric Routh of EBI Consulting
conducted the investigation at the Subject Property on December 21, 2022.
1.1 BACKGROUND
EBI was requested to conduct a Phase II ESA to evaluate the potential impact to the Subject Property
from the following item of environmental concern identified in EBI’s (November 17, 2022) Transaction
Screen report:
The Subject Property was identified in the underground storage tank (UST) database as Main Post
Office at 1514 Main Street. The UST listing identifies the subject property with a 1,000-gallon
heating oil tank installed on May 6, 1961. The tank is listed as constructed of single-walled steel. The
database does not identify a tank status or if the tank was permanently closed. EBI conducted a
search of available records online at the North Carolina Department of Environmental Quality
(NCDEQ) via their Public Records Search-UST Permits and Inspection Program, and did not identify
any records for the subject property. EBI submitted a request to the NCDEQ Winston Salem
Regional Office, to speak with the NCDEQ regarding the UST at the subject property. Mr. Michael
Phelps, Environmental Supervisor with the Division of Waste Management stated that the UST is a
non-registered tank and does not get inspected or require closure notification, so the NCDEQ does
not have any info on tank other than registration. Mr. Phelps checked their Registered UST database
and could not find any site on Main Street in Ramseur so he did not think the corrective action
branch has anything either, so the NCDEQ could not be sure if tank is still there or not. Based upon
the absence of documented removal and closure, the presence of the heating oil UST is considered
a Potential Environmental Concern (PEC) to the Subject Property.
1.2 STATEMENT OF OBJECTIVES
The primary objective of this Phase II ESA is to evaluate potential impact to the Subject Property from
the potential environmental concern (PEC) identified in the transaction screen prepared by EBI
(November 17, 2022) for the purpose of providing sufficient information regarding the nature and
potential extent of contamination to assist in making informed business decisions about the property;
and where applicable, providing the level of knowledge necessary to satisfy the innocent purchaser
defense under CERCLA. The investigation focused on the former heating oil UST.
In order to achieve the objectives of this investigation, EBI performed the following tasks:
Contacted the local utility locating service, North Carolina 811 (Ticket #A223491515) prior to
undertaking subsurface explorations on-site.
Contracted East Coast Geophysics, Inc. of Bensalem, Pennsylvania to conduct a ground penetrating
radar (GPR) survey of the accessible exterior areas of the Subject Property in an attempt to confirm
the presence or absence of potential remaining USTs and to clear each boring location before
undertaking subsurface explorations on-site.
Advanced three borings by Geoprobe direct push drill rig to depths of 14 to 19 feet below ground
surface (bgs).

Collected four-foot soil samples continuously, field screened the vapor headspace of the soil
samples for total ionizable volatile organic compounds (VOCs) using a photoionization detector
(PID), and described the physical characteristics of the soil samples on boring logs.
Selected two soil samples per boring, prepared, and submitted the samples under chain-of-custody
documentation to a North Carolina-certified independent laboratory for analysis of total petroleum
hydrocarbons (TPH) - diesel range organics (DRO) via United States Environmental Protection
Agency (EPA) Method 8015B, VOCs via EPA Method 8260, and polynuclear aromatic hydrocarbons
(PAHs) via EPA Method 8270.
Prepared this summary of pertinent information obtained during this investigation including
accompanying illustrations and appendices, along with EBI’s findings and preliminary conclusions
regarding the presence or absence of contamination in soils beneath the Subject Property in the
areas investigated.
1.3 LIMITATIONS AND ASSUMPTIONS
This Report was prepared for the use of American Postal Infrastructure Partners. It was performed in
accordance with ASTM E1903-19, accepted practices of other consultants undertaking similar studies at
the same time and in the same locale under like circumstances. The conclusions provided by EBI are
based solely on the information obtained during the subsurface investigation. EBI renders no opinion as
to the presence of potential contamination in the areas not investigated. The observations in this Report
are valid on the date of the investigation. Any additional information that becomes available concerning
the Subject Property should be provided to EBI so that our conclusions may be revised and modified, if
necessary. This Report has been prepared in accordance with the proposal approved by American Postal
Infrastructure Partners and with the limitations and assumptions described below, all of which are integral
parts of this Report. No other warranty, expressed or implied, is made.
Limitations
1.The observations described in this Report were made under the conditions stated herein. The
conclusions presented are based solely upon the services described, and not on scientific tasks or
procedures beyond the scope of described services or the time and budgetary constraints imposed
by Client. The work described in this Report was carried out in accordance with terms and
conditions in our Authorization Letter and Agreement for Environmental Services regarding the
Site, which are incorporated herein by references.
2.In preparing this Report, EBI has relied on certain information provided by state and other
referenced parties, and on information contained in the files of federal, state and/or local agencies
available to EBI at the time of the assessment. Although there may have been some degree of
overlap in the information provided by these various sources, EBI did not attempt to independently
verify the accuracy or completeness of all information reviewed or received during the course of
these Environmental Services.

3.Observations were made of the Site and of structures on the Site as indicated within the Report.
Where access to portions of the Site or to structures on the Site was unavailable or limited, EBI
renders no opinion as to the presence of oil or hazardous materials (OHM) in that portion of the
Site or structure. In addition, EBI renders no opinion as to the presence of OHM or the presence
of indirect evidence relating to OHM where direct observation of the interior walls, floor, or ceiling
of a structure on a Site was obstructed by objects or coverings on or over these surfaces. No
representations concerning insulating material is expressed or implied.
4.EBI did not perform testing or analyses to determine the presence or concentration of asbestos,
radon, or lead at the Site unless specifically stated otherwise in the Report. Similarly, no
investigation of dust or air quality was conducted unless specifically stated otherwise in the Report.
5.The purpose of this Report is to assess the physical characteristics of the Site with respect to the
presence of OHM in the environment. No specific attempt was made to determine the compliance
of present or past owners or operators of the Site with federal, state, or local laws or regulations
(environmental or otherwise).
6.Except as noted in the Report, no quantitative laboratory testing was performed as part of the
assessment. Where such analyses have been conducted by an outside laboratory, EBI has relied
upon the data provided, and has not conducted an independent evaluation of the reliability of this
data.
7.Any qualitative or quantitative information regarding the Site, which was not available to EBI at the
time of this assessment may result in a modification of the representations made herein.
8.It is acknowledged that EBI judgments shall not be based on scientific or technical test or procedures
beyond the scope of the Services or beyond the time and budgetary constraints imposed by Client.
It is acknowledged further that EBI conclusions shall not rest on pure science but on such
considerations as economic feasibility and available alternatives. Client also acknowledges that,
because geologic and soil formations are inherently random, variable, and indeterminate in nature,
the Services and opinions provided under this Agreement with respect to such Services, are not
guaranteed to be a representation of actual conditions on the Site, which are also subject to change
with time as a result of natural or man-made processes, including water permeation. In performing
the Services, EBI shall use that degree of care and skill ordinarily exercised by environmental
consultants or engineers performing similar services in the same or similar locality. The standard of
care shall be determined solely at the time the Services are rendered and not according to standards
utilized at a later date. The Services shall be rendered without any other warranty, expressed or
implied, including, without limitation, the warranty of merchant ability and the warranty of fitness for
a particular purpose.
9.Client and EBI agree that to the fullest extent permitted by law, EBI shall not be liable to Client for
any special, indirect or consequential damages whatsoever, whether caused by EBI’S negligence,
errors, omissions, strict liability, breach of contract, breach of warranty or other cause of causes
whatsoever.
Assumptions
1.This Phase II ESA does not address the evaluation of business environmental risks in light of data
collected through the Phase II ESA process. Such evaluation is a function of site and transaction-
specific variables, and of the user’s objectives and risk tolerance. This practice contemplates that the
Phase II ESA process was planned and conducted with such variables in mind, and that the user will
evaluate legal, business and environmental risks in light of known data relating to the particular site
and transaction, and in consultation with legal and business advisors as well as the Phase II Assessor.

2.The ASTM E1903-19 does not define the threshold levels at which target analytes pose a concern of
significance to the user. Users may apply this practice not only in light of applicable regulatory
criteria and relevant liability principles, but also to meet self-defined objectives.
3.The scope of work for this Phase II ESA is site-specific and context-specific. The assessment
process defined by ASTM E1903-19 is intended to generate sound, objective, and defensible
information sufficient to satisfy diverse user objectives.
4.No Phase II ESA can eliminate all uncertainty. Furthermore, any sample, either surface or
subsurface, taken for chemical testing may or may not be representative of a larger population.
Professional judgment and interpretation are inherent in the process, and even when exercised in
accordance with objective scientific principles, uncertainty is inevitable. Additional assessment
beyond that which was reasonably undertaken may reduce the uncertainty.
5.Even when Phase II ESA work is executed competently and in accordance with ASTM E1903-19, it
must be recognized that certain conditions present especially difficult target analyte detection
problems. Such conditions may include, but are not limited to, complex geological settings, unusual
or generally poorly understood behavior and fate characteristics of certain substances, complex,
discontinuous, random, or spotty distributions of existing target analytes, physical impediments to
investigation imposed by the location of utilities and other man-made objects, and the inherent
limitations of assessment technologies.
6.The Phase II ESA is intended to develop and present sound, scientifically valid data concerning actual
site conditions. It shall not be the role of the Phase II Assessor to provide legal or business advice.
1.4 SPECIAL TERMS AND CONDITIONS
This Phase II ESA (the report) has been prepared to assist American Postal Infrastructure Partners in its
underwriting of a proposed mortgage loan on the Subject Property. This report can be relied upon by
only the parties stated in the transmittal letter at the front of this report. EBI’s liability to a purchaser
wishing to use this report is limited to the cost of the report. Amendments to EBI’s limitations as stated
herein that may occur after issuance of the report are considered to be included in this report.
Payment for the report is made by, and EBI's contract and report extends to American Postal
Infrastructure Partners only, in accordance with our Standard Conditions for Engagement and,
Authorization Letter and Agreement for Environmental Services.

2.2 PHYSICAL SETTING
Information regarding the physical settings at the Subject Property and immediate vicinity is summarized
below:
PHYSICAL SETTING DESCRIPTIONS
Regional Geology Information concerning the geology of the Subject Property was obtained from the
USGS National Water Summary, North Carolina region (1984). The Subject
Property is located within the Piedmont physiographic province, which is
characterized by gently rolling terrain and slow-flowing streams and is underlain by
hard crystalline and igneous rocks that are covered nearly everywhere by a clayey
or sandy regolith consisting of weathered parent rock material and alluvium.
Depth to Bedrock Bedrock was not encountered during the investigation.
Surficial Features Surface drainage on the Subject Property occurs over land to the adjoining wooded
land, primarily to the west. No indication of cross-lot runoff, swales, drainage
flows, or active rills or gullies were observed on the Subject Property.
Soil Stratigraphy
Encountered during
the Investigation
Soil stratigraphy encountered during the investigation consisted of approximately 8
to 9 feet of grayish/reddish/orangeish-brown clay with lesser amounts of sand,
underlain by brown/tan sand and clay and saprolite.
Estimated Direction of
Groundwater Flow
Local groundwater gradient is expected to follow surface topography; therefore,
groundwater flow near the Subject Property is expected to flow to the west.
Groundwater depths and flow gradients are best evaluated by a subsurface
investigation involving the installation of at least three groundwater-monitoring
wells, survey of well elevations, and precise measurements of hydraulic head.
Calculation of groundwater flow directions based on relative differences of
hydraulic head on the Subject Property was not included in this scope of work.
Depth to
Groundwater
(encountered during
the investigation)
Groundwater was not encountered during the investigation.

2.5 SUMMARY OF PREVIOUS ENVIRONMENTAL ASSESSMENTS
EBI was requested to conduct a Phase II ESA to evaluate the potential impact to the Subject Property
from the former UST based on the following recognized environmental concerns identified in EBI’s
(November 17, 2022) transaction screen Phase I ESA report:
The Subject Property was identified in the UST database as Main Post Office at 1514 Main Street.
The UST listing identifies the subject property with a 1,000-gallon heating oil tank installed on May 6,
1961. The tank is listed as constructed of single-walled steel. The database does not identify a tank
status or if the tank was permanently closed. EBI conducted a search of available records online at
the NCDEQ via their Public Records Search-UST Permits and Inspection Program, and did not
identify any records for the subject property. EBI submitted a request to the NCDEQ Winston
Salem Regional Office, to speak with the NCDEQ regarding the UST at the subject property. Mr.
Michael Phelps, Environmental Supervisor with the Division of Waste Management stated that the
UST is a non-registered tank and does not get inspected or require closure notification, so the
NCDEQ does not have any info on tank other than registration. Mr. Phelps checked their
Registered UST database and could not find any site on Main Street in Ramseur so he did not think
the corrective action branch has anything either, so the NCDEQ could not be sure if tank is still
there or not. Based upon the absence of documented removal and closure, the presence of the
heating oil UST is considered a PEC to the Subject Property.

3.0 RATIONALE AND WORK PERFORMED
3.1 RATIONALE
3.1.1 Conceptual Model
The Conceptual Model is a representation of hypothesized current site conditions, which describes the
physical setting characteristics of a site and the likely distribution of target contaminants (in soil, air,
ground water, surface water and/or sediments) that might have resulted from a known or likely release
and the risk they pose to human and/or ecological receptors. This Conceptual Model takes into
consideration the potential distributions of contaminants with respect to the properties, behaviors and
fate and transport characteristics of the contaminant in a setting such as that being assessed. The
sampling plan was designed to provide for the collection of potentially contaminated environmental
media, if they occur, at locations and depths where the highest concentrations are likely to occur.

2.Construction Worker exposure is limited due to short exposure duration
3.1.2 Rationale for Soil Boring Placement
The rationale for the placement of the soil borings was based on the 1) the Likely Release Areas that
target analytes were first introduced into environmental media as a result of a release; and 2) the likely
vertical and horizontal migration of the release.

3.1.3 Chemical Testing Plan
The chemical testing plan was designed to detect the target analytes that are present in, or have been
released or potentially have been released to, environmental media at the site, and which are of interest
in the context of the particular Phase II ESA and its objectives, the presence of which will be sought and
concentrations of which will be quantified through chemical testing.
3.1.4 Deviations from the Work Plan
There were no deviations to the work plan.
3.2 EXPLORATION, SAMPLING, AND TEST SCREENING METHODS
3.2.1 Ground Penetrating Radar Survey
EBI contracted East Coast Geophysics, Inc. of Bensalem, Pennsylvania to conduct a ground penetrating
radar (GPR) survey of the accessible exterior areas of the Subject Property in an attempt to confirm the
presence or absence of potential remaining USTs. The GPR survey was conducted at the Subject
Property on December 21, 2022. GPR equipment was used in an attempt to locate potential USTs as
well as to define the presence, size, and depth of any potential USTs and/or former UST locations. GPR
is a geophysical technique, which uses electromagnetic waves for shallow subsurface reconnaissance and
exploration. An electromagnetic impulse in the form of ultra high-frequency radio waves is emitted into
the ground by the transmitting antenna, and the resulting reflection of transfer of waves from
contamination plumes, boundary layers, or buried objects is detected by a receiving antenna. The
presence of buried objects or significant changes in conductivity of the layers will cause the
electromagnetic wave to be reflected. These images provide direct information concerning subsurface
conditions. EBI notes that due to surface conditions and subsurface content, the GPR signal penetration
was estimated at 1 to 3 feet in the majority of the survey area. This penetration was reduced in areas of
concrete cover. In addition, due to the dielectric properties of the subsurface, plastic polymer and
fiberglass utilities may not have been detected. All field services were conducted in compliance with the
general industry standard practices.
The results of the GPR survey did not identify anomalies indicative of a UST located beneath the
surveyed areas of the Subject Property. GPR transects imaged what appeared to be a former
excavation located on the northwest corner of the Subject Property building. The potential former
excavation measures approximately 13 feet by 6 feet. The feature is located on the northwest corner of
the Subject Property building. The feature is located below a cutout concrete pad and an AST. A copy
of the GPR report is presented in Appendix E.
3.2.2 Pre-Drilling Activities
Cardno Inc. requested North Carolina 811 to mark-out the location of Subject Property utilities on
December 15, 2022. Clearance for drilling at the Subject Property was granted for after 7:00 AM on
December 20, 2022. EBI also contracted with a private utility locating company, East Coast Geophysics
Inc. to clear each boring location before undertaking subsurface explorations on-site.

Personal health and safety precautions were followed in accordance with applicable federal and state law
or local equivalents and any requirements imposed by the owner, occupant, or field personnel. EBI
prepared a site-specific health and safety plan (HASP) and conducted a health and safety meeting with
the onsite personnel prior to the drilling activities. No additional pre-drilling activities were performed
as part of this investigation.
3.2.3 Soil Borings
A total of three borings were advanced at the Subject Property. All of the soil borings were advanced
using a direct push drill rig Cardno Inc. of Richmond, Virginia. Four-foot soil samples were collected
continuously during the advancement of the borings. EBI recorded soil sampling information and the
physical characteristics of each soil sample onto boring logs presented in Appendix B.

Boring locations are illustrated on Figure 3, Boring Location Map.
3.2.4 Field Screening
The vapor headspace of each soil sample was field-screened using a PID. The PID provides a reading of
total ionizable VOCs. The PID was calibrated with an isobutylene standard, to measure total VOCs as
isobutylene equivalents. The PID has a practical sensitivity of approximately one part per million by
volume (ppmV). PID readings should not be considered as exact measurements, but as relative readings
of VOCs between locations. The soil samples were placed in a ziplock bag approximately three-
quarters full with the soil to be analyzed, which was sealed for approximately 10 minutes in a warm
(>60˚ F) location for equilibration. The headspace analysis was conducted by inserting the probe of the
PID through an opening in the zip-lock bag and into the space above the soil sample.
Petroleum odors were observed in soil from borings B1 and B3. PID readings ranged from 0.0 to 278.3
parts per million (ppm). The PID results are noted in the Boring Logs provided in Appendix B.

3.2.5 Soil Sampling and Analysis
Selected “grab” soil samples were collected in laboratory-provided sample containers. Each sample was
labeled/logged onto a chain-of-custody form, and placed in a cooler with ice for preservation in
accordance with current Federal EPA SW-846 (3rd ed.). The samples were submitted to an
independent qualified laboratory (Pace Analytical) for analyses. The samples were analyzed for the target
analytes noted in Table 3.2.3.
Samples submitted for VOC analysis were also preserved with methanol in accordance with EPA
Method 8260.
In order to ensure that no cross-contamination between samples occurred, all non-dedicated sampling
equipment was decontaminated after the collection of each sample. Sampling equipment was scrubbed
with a brush to remove loose material and then washed thoroughly with a laboratory grade detergent
and water to remove all particulate matter and surface film. After washing, each piece and brush was
rinsed with clean distilled water. Dedicated sampling equipment such as sampling liners and nitrile gloves
were properly disposed of after the handling of each sample was complete. Samples were then collected
using clean disposable gloves and laboratory-provided glassware appropriate for the specified analysis.
3.2.9 Abandonment of Borings
Upon completion of the soil sampling activities, each soil boring was filled with the soil cuttings
generated during the sampling activities. The remaining void in each borehole was filled with granular
bentonite. The top two to four inches were backfilled with asphalt and compacted.

5.0 FINDINGS & CONCLUSIONS
We have performed a Phase II ESA at the property at 1514 Main Street, North Carolina, in general
conformance with the scope and limitations of ASTM E1903-19 and for the following objectives:
The primary objective of this Phase II ESA is to evaluate potential impact to the Subject Property
from the PEC identified in the transaction screen prepared by EBI (November 17, 2022) for the
purpose of providing sufficient information regarding the nature and potential extent of
contamination to assist in making informed business decisions about the property; and where
applicable, providing the level of knowledge necessary to satisfy the innocent purchaser defense
under CERCLA. The investigation focused on the former heating oil UST.
Findings
The results of EBI's Phase II ESA revealed:
On December 21, 2022, EBI conducted a GPR survey was completed to determine if any former
UST exist at the Subject Property. The results of the GPR survey did not identify anomalies
indicative of a UST located beneath the surveyed areas of the Subject Property. GPR transects
imaged what appeared to be a former excavation located on the northwest corner of the Subject
Property building. The potential former excavation measures approximately 13 feet by 6 feet. The
feature is located on the northwest corner of the Subject Property building. The feature is located
below a cutout concrete pad and an AST.
On December 21, 2022, EBI conducted a Phase II ESA to assess subsurface conditions at the Subject
Property. A total of three soil borings were advanced at the Subject Property. Groundwater was
not encountered during the investigation. All of the soil borings were advanced using a direct push
drill rig. The samples were submitted to a North Carolina-certified laboratory, Pace Analytical, for
analysis of VOCs via EPA Method 8260, PAHs via EPA Method 8270, and TPH-DRO via EPA
Method 8015B.
The analytical results revealed that concentrations of TPH-DRO, VOCs, and PAHs were detected
above laboratory detection limits in the soil samples analyzed. Insert description here based on
residential/industrial standards
Conclusions
The results of the GPR survey did not identify anomalies indicative of a UST located beneath the
surveyed areas of the Subject Property. GPR transects imaged what appeared to be a former
excavation located on the northwest corner of the Subject Property building. The potential former
excavation measures approximately 13 feet by 6 feet.
The analytical results revealed that concentrations of TPH-DRO, VOCs, and PAHs were detected
above laboratory detection limits in the soil samples analyzed. None of the concentrations
identified exceeded the NCDEQ MSCCs for Commercial/Industrial direct contact. The
concentrations of TPH-DRO, naphthalene and several PAHs exceeded the NCDEQ MSCCs for Soil
to Groundwater and Residential direct contact in the soil samples collected.
EBI notes that according to the NCDEQ Division of Waste Management (DWM), if contamination is
discovered or evidence of a release is identified, a reporting condition to the NCDEQ DWM exists.

6.0 RECOMMENDATIONS
Based on the findings and conclusions of this Phase II ESA, EBI recommends the following:
EBI notes that due to the detection of petroleum constituents in the soil, a reporting requirement to
the NCDEQ appears to exist. EBI recommends providing the results to the owner/operator. The
owner/operator should discuss the NCDEQ reporting requirements with their legal counsel. If
reported to the NCDEQ, upon completion of their review of this report, additional investigation
may be required to further evaluate the petroleum impact.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial
calibration (ICAL).
J The identification of the analyte is acceptable; the reported value is an estimate.
J1 Surrogate recovery limits have been exceeded; values are outside upper control limits.
J2 Surrogate recovery limits have been exceeded; values are outside lower control limits.
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.
J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
J7 Surrogate recovery cannot be used for control limit evaluation due to dilution.
V The sample concentration is too high to evaluate accurate spike recoveries.

1. BACKGROUND AND PROJECT OBJECTIVES
The subject property at 1514 Main Street in Ramseur, North Carolina consists of an active US
Post office. Surface conditions consistent of concrete, asphalt, soil, and grass. Site project
objectives are:
• Locate all detectable underground utilities adjacent to the client proposed soil borings.

• Scan the subject property and client specified areas for underground anomalous features
such as underground storage tanks (UST), UST piping, and former excavations.

2. EQUIPMENT

This project used the following equipment to perform the geophysical survey on the property.

• GSSI SIR-3000 Cart Mounted Ground Penetrating Radar System
Ground Penetrating Radar is a non-invasive geophysical method in which electromagnetic
pulses probe the subsurface, allowing targets to be imaged in real time. The EM pulses that
are transmitted into the subsurface are reflected from various interfaces within the ground,
including soil horizons, ground water, and manmade features such as underground storage
tanks and utilities. The GPR antenna consists of a transmitter, which is used to create the EM
pulse, and a receiver which collects returning signals. The high frequency waves created by
the antenna can be generated in a range of 10 MHz to 2.6 GHz. The frequency of the antenna
will vary the depth of penetrations, signal clarity, and attenuation into the subsurface. The
antenna used for general field work by ECG is 400 MHz; this frequency range has the
capability to transmit to a depth of up to 10 feet below ground surface. Surface and
subsurface conditions can greatly reduce the effective depth of the signal penetration; these
conditions include conductive soils, slag/fill material and standing water.
• Radiodetection RD7000+
RD7000 is an advanced high-range precision utility detector capable of detecting utilities up
to 15 feet below ground surface. The RD7000+ has the capability of locating a variety of
pipes and cables using either passive or active modes. Passive signals can be traced with only
the transmitter using “natural” signals present in many conductors. These signals can be
generated from an array of sources including power cables, power system return currents, and
long wave radio frequencies. Active signals are known AC frequencies induced onto a target
pipe or cable. User induced signals can help positively identify lines throughout areas of
congested utilities.
• Fisher TW-6 Pipe and Cable Locator
The Fisher TW-6 Pipe and cable locator uses electromagnetic induction to locate conductive
materials, such as manholes, tanks, pipes, cables, and other metallic materials in the
subsurface. The transmitter generates an AC current which produces an electromagnetic field
similar to a dipole magnet. When the transmitter passes over a conductive feature, the
generated electromagnetic field becomes distorted as a result of the interference with the
natural electromagnetic field created by the conductive feature. The distortion of the
generated field is detected by the receiver which emits a tone that is correlated to the
conductivity of the feature.

3. PROCEDURE
ECG personnel began with a utility survey utilizing active detection with the RD-7000+. This is
done by directing hooking up to known surface features across the site such as valves, exposed
lifts, and fill ports. The surveyor then performed a passive scan with the RD-7000+ receiver to
detect any energized utilities that may have not been located with the active scan. Any detected
utilities were then marked in the field.
ECG personnel then walked across the survey area with the TW-6 in 3-5 foot spacing increments.
The approximate size and shape of any conductive targets detected was then marked in white and
will be further investigated with GPR.
GPR was then utilized to confirm the approximate depth of any utilities detected with the RD-
7000+ and the size, shape, and depth of any anomalies located with the TW-6. ECG personnel
then scanned the remaining portions of the property in 3-5 foot spacing increments for any other
anomalous features or utilities not detected with the RD-7000+ or TW-6.

4. RESULTS
• Underground Utilities – No utilities were detected in proximity to the sample locations,

• Potential Former Excavation
o A potential former excavation was detected with GPR transects. The feature is
located on the northwest corner of the subject building. The potential former
excavation measures approximately 13 feet by 6 feet. GPR transects imaged
disturbed soils above the anomalous area. The feature is located below a cutout
concrete pad and an AST.
No other anomalous features were observed at the subject site.

5. SITE LIMITATIONS

• Ground Penetrating Radar – GPR depth of penetration was limited to 1-3 feet bgs. The
limiting factor was signal attenuation from near surface soils
• Metallic Structures – The TW-6 cannot be utilized within close proximity to metallic
features such as, transformers, vehicles, and reinforced concrete.

6. DISCLAIMER

The limitations of a geophysical survey from both the site and equipment are important to
consider when performing intrusive work at a survey site. The equipment is unable to maintain a
constant depth of penetration or a constant level of effectiveness over the course of a survey due
to subsurface and environmental conditions. The results provided both in this report and in the
field should be used in conjunction with other methods including but not limited to, site plans, as-
builts, sanborn maps, field observations, public-mark out services, soft-digging, pre-clearing, and
historical documentation of the site. No survey or survey method can accurately show an exact
image of all subsurface conditions. The presence of non-detectable subsurface utilities and
structures is always a risk at any site. Please take caution when proceeding with invasive work.
