1.0 INTRODUCTION
On behalf of the responsible party, Barbara Linker et al, Terraquest Environmental Consultants,
P.C. has prepared this Initial Abatement Action Report for the Barbara Linker et al property
located at 1238 Union St. S in Concord, Cabarrus County, North Carolina. This report documents
the closure of a 550-gallon heating oil UST and subsequent excavation of contaminated soil in
November 2020.
The site's location and layout are depicted in Figures 1 and 2. Environmental acronyms used in
this report are detailed in Appendix A along with Terraquest's technical methods and standard
procedures.
2.0 UST REMOVAL & RELEASE DISCOVERY
The UST was installed off the southwest side of the residence during its construction in 1965 and
was replaced with an aboveground storage tank (AST) in the 1990's. On November 18, 2020 prior
to excavating the tank, Terraquest supervised the removal of 425 gallons of residual liquid
composed mostly of water from the UST by CCI of Salisbury, NC. The 550-gallon heating oil tank
was buried approximately 20 inches below ground level (BGL) and was excavated and taken
offsite for environmentally -sound disposal by CCI on November 18, 2020. The dimensions of the
UST were 46 inches wide by 74 inches long. The tank's former location is shown on Figure 2.
Following UST removal, Terraquest inspected the UST and noted holes up to 1.4-inch in size along
the sides and seams. Terraquest collected a soil sample CS1 from beneath the UST at a depth of
5.5 feet BGL. The soil sample was screened using a photoionization detector (PID) and revealed
the presence of heating -oil type contaminants with a detected measurement of 397.1 parts per
million (ppm). This screening measurement coupled with the stained soil and noted holes in the
UST indicated a release of heating oil had occurred from the UST. The CS1 soil sample collected
for analysis was placed in the proper laboratory -prepared sampling containers, labeled with the

project name, project number, sample identification, required analysis, and date and time of
collection. The sample was immediately placed on ice and analyzed before the expiration of an
analytical method's prescribed holding time. Chain -of -custody documentation was maintained
for the soil sample prior to an analysis using a UVF Trilogy unit for TPH Diesel -Range Organics
(DRO) and Gasoline -Range Organics (GRO). Analytical results of the CS1 soil sample revealed
contaminant concentrations above the North Carolina Department of Environmental Quality
Division of Waste Management UST Section (NCDEQ DWM-UST) Actions Limits for both the TPH
GRO and DRO methods. Table 1 summarizes the sample depth and detected concentrations of
the CS1 soil sample. The locations of the soil sample is identified in Figure 2. The complete
analytical report is included in Appendix B.
3.0 REMEDIAL EXCAVATION
With the PID screening measurement, stained soil, and noted holes, Michael Linker, a
representative of the property owner, directed Terraquest to supervise the excavation of
contaminated soil beneath and surrounding the former heating oil UST. The impacted soil was
excavated using a mini excavator to a depth of seven feet BGL where bedrock was encountered.
All of the contaminated soil above the bedrock and from the sidewalls was removed. Soil samples
SW1 through SW4 were collected at the sidewall limits and sample BE1 was collected at the base
of the excavation from soils immediately above the bedrock prior to their removal. The SW1
through SW4 and BE1 soil samples collected for analysis were placed in the proper laboratory -
prepared sampling containers, labeled with the project name, project number, sample
identification, required analysis, and date and time of collection. The samples were immediately
placed on ice and analyzed before the expiration of an analytical method's prescribed holding
time. Chain -of -custody documentation was maintained for the soil samples. The SW1 through
SW4 soil samples were analyzed using a UVF Trilogy unit for TPH DRO and GRO. The BE1 soil
sample was submitted to a NC -certified laboratory for analysis per EPA Method 8260 + MTBE +
IPE (volatile organics), EPA Method 8270 Base Neutral and Acid Extractable (semi -volatile

organics), Massachusetts Department of Environmental Protection (MADEP) methods for volatile
petroleum hydrocarbons (VPH) and extractable petroleum hydrocarbons (EPH).
The four sidewall samples SW1 through SW4 results were either below the NCDEQ DWM-UST
Actions Limits or the laboratory's sample method detection limits. The BE1 base of excavation
sample was above the TPH Action Limits and had detected concentrations above the Soil -to -
Groundwater Maximum Soil Contaminant Concentrations (S-t-G MSCCs) and Residential MSCCs.
Soil contamination was excavated down to the bedrock surface and all of the excavatable
contaminated soil was removed in the base and sidewalls of the former UST basin. The limits of
the final excavation measured nine feet wide by sixteen feet long. Table 1 summarizes the
sample depth, PID measurements, and detected concentrations of the soil samples. The
locations of the soil samples are identified in Figure 2. The complete analytical reports are
included in Appendix B.
Fill dirt obtained from Keller Dirt and Gravel of Kannapolis, NC was used to backfill the excavation.
Two loads of contaminated soil totaling 32.65 tons were removed and taken offsite for disposal
at Alternative Energy Solutions of NC, LLC in Thomasville, NC. The weight -certified soil disposal
manifests are provided in Appendix C.
4.0 GROUNDWATER INVESTIGATION
Groundwater was not encountered or investigated as part of this phase of field work.
5.0 FREE PRODUCT CHECK
Free product was not encountered during site activities.

6.0 POTENTIAL SOURCES OF PETROLEUM HYDROCARBONS
The primary source of petroleum hydrocarbons for this release incident was the former heating
oil UST. A heating oil AST was noted immediately adjacent to the former heating oil UST and is
currently supplying the residence's furnace. An inspection of the AST and surrounding surface
soils do not indicate that a release incident from the AST has occurred and is contributing to the
UST release.
7.0 NATURE AND ESTIMATED QUANTITY OF RELEASE
The nature of the release is petroleum as heating oil from the former non-commercial UST. The
amount of the release is unknown. A UST-61 24-Hour Release and UST Leak Reporting Form is
provided in Appendix D.
8.0 SITE AND VICINITY DESCRIPTION
The site is located in a residential and commercial area located south of Concord, NC. The subject
and surrounding properties to the north, east, and west have a residential zoning classification.
The surrounding properties to the south have a commercial zoning classification. The New Grace
Baptist Church is located approximately 1,100 feet to the northwest. The site and the
surrounding properties derive their drinking water from the City of Concord municipal water
supply system. The subject property residence is connected to a septic system located south of
the residence. A water supply well that formerly supplied the subject property residence was
noted within 30 feet of the former UST location. The well is currently not in use, but not
abandoned. No additional water supply wells were noted within a 150-foot radius from the
former UST location. The location of the water supply well is depicted in Figure 2.
According to the Geologic Map of North Carolina, the site lies in the Charlotte Belt of the
Piedmont Physiographic Province (Brown, et al., 1985) and has been mapped as having a
Initial Abatement Action Report Barbara Linker et al Property

metamorphosed quartz diorite bedrock lithology. On a regional scale, the Piedmont is
characterized by gently rolling, well rounded hills and long low ridges with a few hundred feet of
elevation difference between the hills and valleys. The closest surface water body features are
intermittent streams located approximately 1,200 feet to the northeast and approximately 1,400
feet to the west. The eastern stream feeds into Cold Water Creek located approximately 4,450
feet to the east and into Irish Buffalo Creek located approximately 4,900 feet to the west. Surface
water features are displayed with topography on Figure 1.
9.0 CONCLUSIONS/RECOMENDATIONS
Terraquest personnel supervised the removal of one heating oil UST in November 2020 at the
Barbara Linker et al property located at 1238 Union St. S in Concord, NC. Initial abatement
activities included the removal of that tank and the excavation and offsite disposal of 32.65 tons
of contaminated soil. Excavation was conducted to the limits possible given the presence of the
onsite structures and features horizontally and bedrock vertically.
Given the removal of the UST, the removal of the excavatable contaminated soil, the non-
commercial status of the UST, and the presence of municipal water, the release incident is a
"LOW" risk eligible for a "No Further Action" Letter and closure of the release incident.
10.0 LIMITATIONS
This report is limited to the investigation of petroleum hydrocarbons in soil and does not imply
that other unforeseen adverse impacts to the environment are not present at or around the
subject facility. In addition, subsurface heterogeneities not identified during the current study
may influence the migration of groundwater or contaminants in unpredicted ways. The limited
amount of sampling and testing conducted during this study cannot practically reveal all
subsurface heterogeneities. Furthermore, the subsurface conditions, particularly groundwater
flow elevations, and water quality may very through time. The opinions and conclusions

TECHNICAL METHODS/STANDARD PROCEDURES
Equipment Decontamination
All soil sampling equipment utilized during site assessment activities is decontaminated according
to standard and accepted protocol. Cleaning solutions range from clean potable water to acidic
solutions or organic solvents depending on the contaminants present at the site. Equipment
utilized at sites, such as hand augers, contaminated with petroleum hydrocarbons, is generally
decontaminated with a low-sudsing detergent such as Luiquinox° and triple rinsed with distilled
water. Larger equipment, such as drill rigs and associated tools, is steam cleaned. All
decontamination procedures are completed within an established decontamination area which is
located away from the active study area. Frequency of equipment decontamination depends on
the nature of work being performed, but in no case is decontamination performed less frequently
than once per test (i.e., soil boring, well installation, sample collection, etc.). Equipment blanks are
collected as a quality control measure when required by job specifications.
Soil Boring Installation
Soil borings are completed using hand -operated sampling tools, truck -mounted drills, or
Geoprobe° drilling rigs depending on the depth of sample collection and other site -specific
conditions. Hand operated stainless -steel bucket augers are utilized to collect soil samples at
regular intervals to determine site stratigraphy and to test for the presence of volatile organic
compounds. Samples retrieved from the hand auger are necessarily disturbed during the augering
process, but can provide accurate information on soil type and contaminant concentrations when
properly interpreted. Soil samples from hand augered borings are generally retrieved at one to
two foot intervals.
Truck -mounted or Geoprobe° drilling equipment is often utilized when sample retrieval depths
exceed twenty feet or subsurface conditions prevent utilization of hand augers (i.e., buried rocks,
wood, bricks or other materials occur in the subsurface). Truck -mounted drilling rigs usually
retrieve soil via a hollow -stem auger/split spoon collection method. Geoprobe° rigs usually employ
a Macro -Core° tube retrieval system.
Hollow stem augers provide relatively undisturbed 2-foot cores of soil samples. Soil samples are
generally collected at five foot intervals utilizing standard penetration test procedures as defined
by the American Society for Testing and Materials (ASTM) or are pushed to the desired depth using
the head of the drill rig. The standard penetration test involves driving a 2" outside diameter by 1-
3/8" inside diameter split -spoon sampler a minimum distance of one foot with a 340-lb. slide
hammer falling a distance of 30 inches.
A Geoprobe° rig is a hydraulically -powered soil probing machine. The probe utilizes static force
and percussion to advance a small diameter sampling device into the subsurface. The sampling
apparatus provides relatively undisturbed 5-foot cores of soil samples. Soil samples are collected

continuously. The Macro -Core° tube contains an inserted poly -vinyl chloride (PVC) liner which
retains the soil sample as the tube is driven into the ground. The Macro -Core° tube is
decontaminated between each 5-foot sample interval in a soil boring using a Liquinox and tap -
water mixture. A new PVC liner is used to collect soil from each sample interval in a soil boring.
Soil samples retrieved from the hollow -stem augers or Geoprobe are then carefully described
according to the Unified Soil Classification System. Soil descriptions are recorded on a soil
boring log.
Soil Sampling
Soils to be analyzed by a North Carolina -certified laboratory are prepared according to the specified
analytical method. Initially, soil samples are removed from the ground using either a hand auger,
backhoe bucket, spilt spoon auger, or a Macro -Core° sampling tube. During the removal, care is
taken to keep the disturbance of the soil structure to a minimum to reduce the loss of
contaminants. Once removed, the samples are placed in the proper sample container for the
specified analytical method. For samples collected for the MADEP VPH and EPA Method 8260, a
TerraCore° sampler is used to collect one 5-gram allotment of soil. The allotment is placed in
methanol -preserved 40 mL vials. Also, one 5-gram allotment of soil is placed into sodium bisulfate -
preserved 40 mL vials (one 5-gram allotment per vial, 2 vials per sample) for the 8260 low
concentration method. A 250-mL glass jar of the sampled soil is also collected to provide moisture
content information. Soils sampled for MADEP EPH, EPA Method 8270 and TPH 5030 and 3550 are
placed in a 250-mLglass jar (for MADEP EPH analysis an amber jar is required). TPH 5030 samples
are preserved in methanol similar to the 8260 analysis. Field personnel wear new, disposable
nitrile gloves during the collection of each sample.
The soil samples are labeled with the sample location, sample identification, date and time of
collection, and the analytical method. The samples are placed on ice, sent to a laboratory, and
analyzed before the expiration of an analytical method's prescribed holding time. Chain -of -custody
documentation is maintained for each sample collected in the field.
If the soil is being sampled for volatile or semi -volatile compounds, a portion of the collected soil is
placed in a sealable bag and screened for volatile organic vapors. Head screening procedures are
described in the following paragraph.
Headspace Screening
Collected soil samples are routinely tested for the presence of volatile organic compounds (VOCs).
After retrieval from the ground, a portion of a soil sample is placed in a sealable plastic bag. The
soil samples are then set aside for approximately five minutes so that volatile constituents present
in the sample can reach equilibrium concentrations with headspace gases in the bag. Once a
suitable time period has passed, the probe of the sampling instrument, typically an Organic Vapor
Monitor (OVM) or a Photo Ionization Detector (PID), is inserted into the bag and the relative
concentration of total VOCs is measured and permanently recorded in a field note book. VOC

concentrations are measured using either a Thermo Electron Corp. Innova Series catalytic OVM or
an Ion Science PhoCheck PID. Both the OVM and PID instrumentation are periodically calibrated
according to the manufacturer's recommended procedures.
The OVM and PID are qualitative tools employed to detect and estimate the concentration of
organic or hydrocarbon vapors. A thin probe is inserted through a small break in the seal of a
bagged soil sample. For the OVM, an air sample from the headspace of the bag is drawn through
the probe into an internal chamber where the vapors are catalyzed. The concentration of the VOCs
is registered on a digital scale in parts per million (ppm). For the PID, an air sample from the
headspace of the bag is drawn across the face of a lamp causing the sample to emit photons, the
presence of which are converted into a VOC ppm reading that is displayed. Oxygen levels are field
calibrated prior to each use. VOC calibration occurs periodically depending upon use by using a
span gas of known concentration in a process recommended by the manufacturer.
Well Installation/Construction
Monitoring wells are installed using hand -operated sampling tools, a truck -mounted drill rig, or a
Geoprobe drilling rig depending on the depth of well and other site -specific conditions. All
monitoring wells are installed according to the requirements of 15A NCAC 2C-Well Construction
Standards. Specifically, individual monitoring wells are constructed of 2-inch diameter, schedule 40
PVC casing riser and screen. The screen interval is generally 10 to 15 feet of machine slotted PVC
with a slot size of 0.010". Only flush threaded joints are used. The annulus space around the
screen is filled with washed filter pack No. 2 sand. The filter pack extends one to two feet above
the top of the screen. A one to two foot -thick bentonite pellet seal is then placed above the filter
pack. The remainder of the well annulus is completely filled with a Portland (Type 1/11) cement
grout mixture. A protective outer steel manhole, locking cap, and concrete pad is installed for each
well.
Type II Monitoring Well Construction
Single -cased monitoring wells are generally used in delineation of groundwater quality within the
surficial aquifer. The wells are constructed of 2-inch diameter, schedule 40 PVC casing and screen.
The screen interval is generally 10 to 15 feet of machine slotted PVC with a slot size of 0.010". Only
flush threaded joints are used. The annulus space around the screen is filled with washed filter
pack No. 2 sand. The filter pack extends one to two feet above the top of the screen. A one to two
foot -thick bentonite pellet seal is then placed above the filter pack. The remainder of the well
annulus is completely filled with a Portland (Type 1/II) cement grout mixture. A protective outer
steel manhole, locking cap, and concrete pad are installed for each well.
Type III Monitoring Well Construction
Double -cased monitoring wells are used in the delineation of groundwater quality within a deeper
portion of the surficial aquifer or an additional aquifer (e.g. aquitard, bedrock). A four to six-inch
outer casing is installed through the surficial aquifer until a sufficient depth or until the deeper

aquifer is encountered. The casing is secured with a Portland -grout collar that is tremmied into the
annular spaced from the bottom of the bore hole to the surface. Once the grout has sufficiently
cured, the bore hole is continued through the bottom of the outer casing to a depth approximately
15 - 20 feet beneath the outer casing. The inner casing is constructed of 2-inch diameter, schedule
40 PVC casing riser and screen. The screen interval is generally 5 to 10 feet of machine slotted PVC
with a slot size of 0.010". Only flush threaded joints are used. The annulus space around the
screen is filled with washed filter pack No. 2 sand. The filter pack extends one to two feet above
the top of the screen. A one to two foot -thick bentonite pellet seal is then placed above the filter
pack. The remainder of the well annulus is completely filled with the same Portland grout mixture
used in the outer casing. A protective outer steel manhole, locking cap, and concrete pad are
installed for each well.
Well Development
Following installation of each well, surging and pumping or bailing techniques will be used to
remove fines from the screened interval. Groundwater is removed from each well until clear water
is retrieved or a noticeable reduction in the amount of silt is achieved. Purged groundwater is
disposed of in an environmentally safe manner.
Groundwater Sampling
Petroleum Sites
Groundwater samples are collected from temporary or permanent monitoring wells according to
established sampling protocol. When multiple monitoring wells or sampling points are sampled,
sampling is completed beginning with the least contaminated well to the most contaminated well,
if it is known. When permanent monitoring wells for petroleum sites are sampled, the well is
purged of a minimum of three well -bore volumes prior to sample collection in order to assure that
sampled water is representative of aquifer conditions. In temporary wells, the first water which
migrates into the open borehole is sampled. Samples from both temporary and permanent
monitoring wells are collected using individually wrapped disposable polyethylene bailers by field
personnel wearing disposable nitrile gloves. Only one well is sampled with a given bailer in order to
prevent sample cross -contamination. During both well purging and sampling, proper protective
clothing and equipment is used and is dependent upon the type and level of contaminants present.
Also, field personnel change gloves between different samples to reduce the chance of cross -
contamination. Water samples are transferred from the bailer to laboratory -prepared sampling
containers using slow emptying devices to reduce the chance of contamination loss through
volatilization. Preservatives, such as acids, are provided by the laboratory in pre -prepared
containers in which collected samples are placed if in -field preservation is necessary. The samples
are labeled with the project name, project number, sample identification, required analysis, and
date and time of collection. The samples are placed on ice, shipped to a certified laboratory, and
analyzed before the expiration of an analytical method's prescribed holding time. Chain -of -custody
documentation is maintained for each sample collected in the field.

Other Groundwater Sampling Protocols
When required by state or federal regulations, low -flow groundwater sampling procedures are
instituted. Groundwater samples collected in low -flow situations are collected using a peristaltic
pump. A peristaltic pump is a type of positive displacement pump. The fluid is contained within a
flexible tube fitted inside a circular pump casing. A rotor with a number of rollers attached to the
external circumference compresses the flexible tube. As the rotor turns, the part of tube under
compression closes thus forcing the fluid to be pumped to move through the tube. Groundwater
parameters such as water level drawdown, pH, conductivity, dissolved oxygen (DO) and turbidity.
Pumping rate, drawdown, and the time or volume required to obtain stabilization of parameter
readings can be used as a future guide to purge the well. Measurements are collected at a pre -
pumping established interval (typically five to ten minutes). Once all or a majority of the
parameters have stabilized forthree successive readings, stabilization has been achieved. In lieu of
measuring all five parameters, a minimum subset would include pH, conductivity, and turbidity or
DO. Three successive readings should be within ± 0.1 for pH, ± 3% for conductivity, and ± 10% for
turbidity and DO.
Upon parameter stabilization, sampling is initiated. Sampling flow rate is maintained at the estab-
lished purge rate or is adjusted slightly to minimize aeration, bubble formation, turbulent filling of
sample bottles, or loss of volatiles due to extended residence time in tubing. The same device used
for purging is used to collect the groundwater sample. Generally, volatile parameters are sampled
first. The sequence in which samples for inorganic parameters are collected is not determined
unless filtered (dissolved) samples are collected. Preservatives, such as acids, are provided by the
laboratory in pre -prepared containers in which collected samples are placed if in -field preservation
is necessary. The samples are labeled with the project name, project number, sample
identification, required analysis, and date and time of collection. The samples are placed on ice,
shipped to a certified laboratory, and analyzed before the expiration of an analytical method's
prescribed holding time. Chain -of -custody documentation is maintained for each sample collected
in the field.
During both well purging and sampling, proper protective clothing and equipment is used and is
dependent upon the type and level of contaminants present. Also, field personnel change gloves
between different monitoring wells or sampling points to reduce the chance of cross -
contamination. When multiple monitoring wells or sampling points are sampled, sampling is
completed beginning with the least contaminated well to the most contaminated well, if it is
known.
Stockpile Sampling
The number of composite samples collected from a stockpile or a total quantity of excavated soil is
based upon the cubic yardage. One composite sample is collected for every 100 cubic yards of
contaminated soil excavated. The volume of a stockpile or total quantity of excavated soil is
calculated by approximating the general geometry of a stockpile or estimating the capacity of the

dump trucks used for hauling. If a stockpile is sampled, a grid pattern is laid out on the stockpile,
dividing the stockpile into segments of approximately 200 cubic yards. Two soil borings are
advanced within a grid and three soil samples are collected from each soil boring at various depths.
The six soil samples are mixed into a composite sample by a trained TerraQuest technician. If truck
loads are sampled, an aliquot sample is collected from the hauling trucks at a frequency based
upon the capacity of the hauling trucks.
Aliquots are gently mixed into a composite sample by a trained TerraQuest technician. Every effort
is made to minimize the loss of contaminants through volatilization. The composited soil samples
are jarred in the appropriate laboratory -prepared containers, labeled with the sample location,
sample identification, date of collection, time of collection, the analytical method, and the
preservative. The samples are placed on ice, shipped to a laboratory, and analyzed before the
expiration of an analytical method's prescribed holding time. Chain -of -custody documentation is
maintained for each sample collected in the field.
Surface Water Sampling
Surface water samples, specifically samples from creeks or streams, are collected from a
moving/flowing portion of the creek or stream to ensure that stagnant water is not collected. Field
personnel are careful to collect samples from flowing areas that are not so turbulent as to cause a
loss of volatile contaminants which might have been contained in the creek's/stream's water.
Samples are collected by field personnel wearing disposable nitrile gloves. Field personnel change
gloves between different locations to reduce the chance of cross -contamination. Samples are
collected directly from the appropriate creek or stream location and placed into the appropriate
laboratory -prepared containers. Preservatives, such as acids, are provided by the laboratory in pre -
prepared containers in which collected samples are placed if in -field preservation is necessary. The
samples are labeled with the project name, project number, sample identification, required
analysis, and date and time of collection. The samples are cooled on ice to approximately four
degrees centigrade, shipped to a certified laboratory, and analyzed before the expiration of an
analytical method's prescribed holding time. Chain -of -custody documentation is maintained for
each sample collected in the field.
Potable Well Sampling
Groundwater samples from potable wells are collected from sampling points, typically spigots,
located in the closest proximity to the potable well pump house as possible. Prior to sample
collection, the water is run for a sufficient amount of time to purge the bladder tank and assure
that sampled water is representative of aquifer conditions. Once purged, the flow rate is reduced
and samples are placed in the appropriate laboratory prepared containers with the appropriate
acid preservatives added if preservation of the sample is necessary. The samples are labeled with
the project name, project number, sample identification, required analysis, and date and time of
collection. The samples are placed on ice, shipped to a laboratory, and analyzed before the
expiration of an analytical method's prescribed holding time. Chain -of -custody documentation is
maintained for each sample collected in the field.

Public Water Supply Line Sampling
Groundwater samples from public water supply lines are collected from sampling points, typically
spigots. To sample the spigot, the flow rate is reduced and samples are placed in the appropriate
laboratory prepared containers. The samples are labeled with the sample location, sample
identification, date of collection, time of collection, and required analytical method. The samples
are placed on ice, shipped to a laboratory, and analyzed before the expiration of an analytical
method's prescribed holding time. Chain -of -custody documentation is maintained for each sample
collected in the field.
Air Sampling
Air samples are collected with the aide of a manually operated MityVac° pump manufactured by
Pristech, Inc. The air sampling process begins by connecting a length of rubber hose from the
MityVac° pump to the port to be sampled, or by hanging the hose inside of an emissions stack in
such a manner as to ensure no outside air causes dilution. Another length of hose is fixed to the
outlet port of the pump and is connected to a new Tedlar bag. Once the pump is hooked up, a
valve on the Tedlar collection bag is opened and air is manually forced into the bag by the pumping
action of sampling personnel.
Field Measurements
Field measurements taken to determine the pH, conductivity, temperature, and dissolved oxygen
concentration of a particular groundwater sample are taken directly after a particular monitoring
well has been adequately purged. This ensures that the groundwater parameter data collected is
representative of the aquifer conditions at a given location. Once purging of the monitoring well is
complete, the decontaminated probe head and cord of the appropriate unit is lowered into the
required monitoring well. If the depth to water in a specific monitoring well is greater than the
length of cord for a particular unit, a new, disposable bailer is slowly lowered into the appropriate
monitoring well and a representative groundwater sample is retrieved. A slow pouring device is
fitted onto the end of the disposable bailer and the sample is slowly poured into a new, disposable
plastic cup. Groundwater parameter data are then collected from the groundwater in the cup
using the required unit.
For pH, conductivity, and temperature, a Hanna Instruments Model 991300 portable meter is
utilized. This unit is periodically calibrated and maintained in accordance with the unit's operations
manual by field personnel. Prior to data collection, the unit is properly decontaminated to prevent
cross -contamination. The unit is decontaminated between each sample. The procedure used for
sample measurement involves lowering the meter's probe into the new, disposable cup containing
the groundwater sample to be measured and slowly stirring the probe to force groundwater across
the probe's membrane. The measurements displayed by the meter are then recorded.
For dissolved oxygen concentration measurements, a YSI° Model 55 Handheld Dissolved Oxygen
System is utilized. This unit is periodically calibrated and maintained in accordance with the unit's

operations manual by field personnel. Prior to data collection, the unit is properly decontaminated
to prevent cross -contamination. The unit is decontaminated between each sample. The procedure
used for sample measurement involves adjusting the unit for the correct altitude where the
sampling will take place and adjusting the reported units desired. Once this is done, the unit's
probe is inserted into the groundwater sample to be measured and the probe is slowly stirred to
force the groundwater across the probe's membrane. The measurements displayed by the unit are
then recorded.
For turbidity measurements, a Hach 2100P Portable Turbidity meter or equal equivalent is utilized.
The unit is calibrated prior to use in accordance with the unit's operations manual by field
personnel. Groundwater samples are collected in glass containers for measurement by the
instrument. The glass containers are washed with bottled -water between each measurement
collection. Once the sample is collected and inserted into the instrument, the measurements
displayed by the instrument are then recorded.

UVF TRILOGY ANALYTICAL REPORT
Project Name: 1238 Union St SE, Concord, NC
Project Number: 16820
Date: 11/20/2020

Standard Technical Procedures
The UVF TRILOGY instrument is a fixed -wavelength fluorometer but uses deep UV LEDS to detect
monoaromatic and polyaromatic hydrocarbons.
SITELAB's CAL-025 GRO Module is used to detect volatile petroleum hydrocarbons in the C6 to C10 range.
This test matches well to EPA Methods for GRO, BTEX, BPH or VOC's using GC/FID instrumentation.
SITELAB's CAL-042 EDRO Module is used to detect petroleum hydrocarbons in the C10 to C36 diesel and
oil range. This test matches well to EPA methods for TPH, EPH, DRO, and others using GC-FID
instrumentation.
Prior to field usage, the UVF TRILOGY is calibrated with five calibration standard solutions per targeted
analyte.
Soil samples are weighed to the nearest gram (i.e. 5.0 g) and added to a 1-ounce HDPE Nalgene bottle
with a measured amount of laboratory grade methanol to the nearest mL (i.e. 10 mL) to create a sample
extract. After addition of both the soil and methanol, the bottle is agitated for several minutes. Next, the
sample rests for several minutes allowing for the soil and methanol extract to separate.
After ample resting time, the methanol extract is collected with a syringe. A filter is connected to the end
of the syringe and dispensed into a clean sample test tube. The test tube is labeled with sample ID and
extract dilution factor (i.e. 2X).
Known amounts of extract are pipetted into a second test tube and diluted with methanol. The sample
ID and dilution factor are labeled on the test tube (i.e. 100X).
Samples are placed into a clean cuvette and carefully inserted into the selected UV Module. Prior to
analyzing the sample, the stored calibration that matches the UV Module being used, is selected. The
UVF TRILOGY produces a result that when multiplied to the dilution factor equals the true TPH value.
Quenching occurs when the detector is swamped by too many or certain type of hydrocarbons, producing
low or negative concentrations. The sample is tested at multiple dilutions to confirm the results are linear
and accurate.
Solvent blank samples are periodically analyzed to confirm the solvent is clean and the calibration of the
machine is maintained.

Flagging Criteria
X In our quality control review of the data a QC deficiency was observed and flagged as noted. MS/MSD recoveries were found to be
outside of the laboratory control limits due to possible matrix /chemical interference, or a concentration of target analyte high enough
to affect the recovery of the spike concentration. This condition could also affect the relative percent difference in the MS/MSD.
B A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or
laboratory contamination.
D The sample(s) were diluted due to targets detected over the highest point of the calibration curve, or due to matrix interference.
Dilution factors are included in the final results. The result is from a diluted sample.
E The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated.
F RPD exceeded lab control limits.
J The target analyte was positively identified below the quantitation limit and above the detection limit.
U Analyte was not detected.
L The LCS data for this analytical batch was reported below the laboratory control limits for this analyte. The department supervisor and
QA Director reviewed data. The samples were either reanalyzed or flagged as estimated concentrations.
H The LCS data for this analytical batch was reported above the laboratory control limits. Supporting QC Data were reviewed by the
Department Supervisor and QA Director. Data were determined to be valid for reporting.
K Sample analyzed outside of recommended hold time.
JN A combination of the "N" and the " Y qualifier. The analysis indicates that the analyte is "tentatively identified" and the associated
numerical value may not be consistent with the amount actually present in the environmental sample.
** Surrogate recovered outside laboratory control limit.
BRL Below Reporting Limit. ND Not Detected.

Definitions of Sources
Tank: means the tank that stores the product and is part of the underground storage tank system
Piping: means the piping and connectors running from the tank or submersible turbine pump to the dispenser or other end -use equipment (Vent, vapor recovery, or fill
lines are excluded.)
Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above
the shear valve)
Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that
connects the submersible turbine pump to the tank
Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.)
Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories (e.g., for releases from vent lines, vapor
recovery lines, and fill lines)
Unknown: identifies releases for which the source has not been determined
Definitions of Causes
Spill: use this cause when a spill occurs (e.g., when the delivery hose is disconnected from the tank fill pipe or when the nozzle is removed from the dispenser)
Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser)
Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion (e.g., puncture of tank or piping, loose fittings, broken
components, and components that have changed dimension)
Corrosion: use when a metal tank, piping, or other component has a release due to corrosion (e.g., for steel, corrosion takes the form of rust)
histallation Problem: use when the problem is determined to have occurred specifically because the UST system was not installed properly
Other: use this option when the cause is known but does not fit into one of the preceding categories (e.g., putting regulated substances into monitoring wells)
Unknown: use when the cause has not been determined

No we did not, but we removed all the soil contamination up to bedrock. We collected one soil sample (BE1) of the soil
immediately above the bedrock to document that the contamination extended to bedrock and then removed the
impacted soil.

Hey Trudy!
We supervised the removal and subsequent soil excavation for a residential non-commercial heating oil UST at 1238
Union St S in Concord NC. The UST-61 is included in the report.
We excavated contaminated soil to achieve a clean closure. We have clean sidewall samples and removed all of the soil
up to 7 feet BGL where we encountered bedrock.
Could you please review the attached Initial Abatement Action Report and let me know if you have any questions!
Thanks!

Good Morning Jonathan,
We spoke by phone on April 14th about this site. You were going to get a groundwater sample from the well on the
parcel. Do you have that data for review?
