ExxonMobil Facility#42650 located at 2415 Maple Avenue, Burlington,Alamance County,
North Carolina(the Site). The objective of the groundwater monitoring and sampling
program is to confirm stable or decreasing concentrations of dissolved-phase chemicals of
concern(COCs)and maintain compliance with the North Carolina Department of
Environment and Natural Resources(NCDENR) Underground Storage Tank(UST)
Program requirements for the Site.
On September 25,2013, twelve(12)groundwater monitoring wells, MW-1, MW-2A, MW-3,
MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, DW-1, and DW-2,were gauged to
determine depth to bottom (DTB), depth to water(DTW)and depth to product(DTP), if
present. Depths to water ranged from 14.74 feet below top of well casing(btoc) in
monitoring well MW-5 to 17.27 feet btoc in monitoring well DW-2.Groundwater flow
direction was documented to be towards the northwest. This is consistent with historically
observed groundwater flow at the site.
Groundwater samples were collected from five(5)groundwater monitoring wells, MW-4,
MW-7, MW-8, MW-9,and MW-10 on September 25, 2013.The maximum concentrations of
selected dissolved-phase COCs found during the September 25, 2013 sampling event are
summarized in the table below.

1.0 Site History and Characterization
Former ExxonMobil (Exxon) Facility#42650, located at 2615 Maple Avenue, Burlington,
Alamance County, North Carolina(the site), is currently a vacant lot utilized for overflow
parking by an adjacent car dealership (Nichol's Dodge). In January 1991, a release was
discovered from an unidentified source during a divestment investigation.Two 8,000-gallon
and one 12,000-gallon gasoline underground storage tanks(USTs), one 10,000-gallon
diesel UST and one 1,000-gallon used oil UST, along with associated piping and
dispensers,were removed in March 1995.
Six aggressive fluid vapor recovery(AFVR)events were conducted in 1997 to recover free
product from the subsurface.A solar powered skimmer was installed in monitoring wells
MW-2 and MW-4 to recover free product from the fourth quarter 1998 to March 1999.The
skimmer was removed after free product was no longer detected in the monitoring wells. A
soil vapor extraction/air sparge(SVE/AS)remediation system was installed in January
1996 as part of a Corrective Action Plan(CAP).The SVE/AS remediation system was
deactivated in June 2001 after site data indicated dissolved phase and adsorbed phase
chemical of concern(COC)concentrations were not being effectively reduced.
In June 2001, impacted soil at the Site was excavated and stockpiled on site for ex situ bio-
remediation.A hydrocarbon impacted area of approximately 30 feet by 40 feet located
between 10 and 18 feet bgs was excavated and stockpiled on site. The existing SVE
remediation system was rerouted to draw air through the stockpile.Additional ventilation
was installed in the stockpile to promote air movement. The excavated area was left open
from June 2001 to April 2002 to allow additional ventilation.Air sparge points connected to
the existing remediation system were installed in the bottom of the excavated area.
The excavation was backfilled with stone and gravel to 9 feet bgs.The remaining volume
was backfilled with the clean overburden and treated soil. COC concentrations in the
backfilled native soil were found to be below applicable cleanup levels. Impacted soils with
COC concentrations above applicable cleanup levels were transported to an offsite
disposal facility.
The site is located in a commercially developed area of Burlington, North Carolina within
the city limits. Topography at the site is flat with a slight slope to the south.The regional
topography slopes west-northwesterly toward an unnamed tributary of Little Alamance
Creek. Soils at the site are silty clays underlying a surface of asphalt and gravel. Beneath
this material is saprolite consisting of silty clays with stains of iron oxide and magnesium
oxide. Regional soils are generally medium-well to well drained soils formed from mixed

mafic and felsic parent rock.The site is located in the Carolina Slate Belt Geologic Province
of North Carolina. Sensitive Receptor Surveys(SRSs)have not identified public or private
potable wells within 1,500 feet or surface water bodies within 500 feet of the site.
Due to the lack of sensitive receptors and COC concentrations above North Carolina Gross
Contamination Level (GCL)standards, North Carolina Department of Environmental and
Natural Resources(NCDENR)classified the Site as"Intermediate". Therefore COC
concentrations in groundwater are being compared to the applicable North Carolina GCL
standards.A site location map is presented in Figure 1 and a site map is shown as Figure
2.
ARCADIS submitted a Notification of Intent to Construct or Operate Injection Wells Form to
the NCDENR—Aquifer Protection Section on July 1,2013. The Notification of Intent Form
recommended the injection of sodium persulfate at three injection well locations including
one existing groundwater monitoring well, MW-4. Additionally, the Notification of Intent
Form recommended the installation of two chemical injection wells, INJ-1 and INJ-2, and
one groundwater monitoring well, MW-11,to serve as replacement for injection well MW-
4/INJ-3. The July 1, 2013 Notification of Intent to Construct or Operate Injection Wells
Form is included as Appendix A.
2.0 Monitoring and Injection Well Installation
On October 15—16, 2013,ARCADIS G&M of North Carolina, Inc. (ARCADIS),
subcontracted Geologic Exploration(GEX)(Vince Federle, NC driller license#A-3552)to
install one groundwater monitoring well, MW-11, and two chemical injection wells, INJ-1
and INJ-2, utilizing hollow stem augers. The groundwater monitoring and chemical
injection wells were installed as indicated in the July 1, 2013 Notification of Intent to
Construct or Operate Injection Wells Form.
The injection wells were constructed of 2-inch diameter, schedule 40 polyvinyl chloride
(PVC)well casing and a 10-foot section of 0.020-inch slotted screen and the groundwater
monitoring well was constructed of 2-inch diameter, schedule 40 PVC well casing and a 10-
foot section of 0.010-inch slotted screen. Each of the groundwater monitoring and injection
wells were installed to 27 feet bgs.The annular space of each well was backfilled with#5
filter sand from the terminal well depth to approximately 2 feet above the screened interval.
A bentonite seal was placed above the sand filter pack(13—15 feet bgs)and neat cement
grout was placed to the surface.The well was completed at the surface with a flush-
mounted, bolt-down manhole assembly, two-foot square concrete pad, locking cap and
lock. Injection well construction records and boring logs are included as Appendix B. The

wells were properly developed upon completion of installation to insure hydraulic
connection with the surrounding soil horizon by being purged of five static well volumes of
water, or until dry.
3.0 Free Product
Gauging activities performed on September 25, 2013 indicated that free product was not
present in any of the gauged groundwater monitoring wells. Prior to the September 25,
2013 groundwater gauging event,free product was historically observed in monitoring
wells MW-2 and MW-4 between January 1998 and November 1999 at a maximum
apparent thickness of 0.42 feet and 0.91 feet, respectively.The last detection of free
product at the site was during the November 10, 1999 gauging event in monitoring well
MW-2 at an observed apparent thickness of 0.01 feet. Free product was historically
recovered by a combination of active remediation,AFVR events, automated skimming and
manual bailing methods. Current and historical groundwater elevations along with free
product thickness data are summarized in Table 1.
4.0 Groundwater Monitoring
4.1 Groundwater Gauging
On September 25, 2013, ARCADIS personnel gauged groundwater monitoring wells MW-
1, MW-2A, MW-3, MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, DW-1, and DW-2.
Gauging was conducted with an oil/water interface probe(IP)prior to purging and sampling
to determine depth to bottom (DTB), depth to water(DTW), and depth to product(DTP), if
present.The IP and attached tape, marked in 0.01-foot increments, were properly
decontaminated before each use with Alconox soap and rinsed with distilled water.The
DTW was measured from the marked survey point on the top of the well casing(TOC).All
measurements were recorded to the nearest 0.01-foot increment.
Free product was not detected in any of the gauged monitoring wells during the September
25, 2013 gauging event. Groundwater elevations ranged from 14.74 feet below top of well
casing (btoc)in groundwater monitoring well MW-5 to 17.27 feet btoc in groundwater
monitoring well DW-2. Current and historical groundwater elevations are summarized in
Table 1.A potentiometric map for the September 25, 2013 groundwater monitoring event is
included as Figure 3. Groundwater flow was depicted to be towards the northwest which is
consistent with historic observed groundwater flow direction.

ARCADIS Report-2013
4.2 Groundwater Sampling
On September 25, 2013, groundwater monitoring wells MW-4, MW-7, MW-8, MW-9, and
MW-10 were purged of stagnant water. Prior to purging, the amount of water to be
removed was calculated using the following formula:
3.1415 x r2 x(TD—DTW)x 7.481 =gallons of water(1 well volume)
Where: r=radius of well(in feet)
TD=total depth of well(in feet btoc)
DTW=depth to water(in feet btoc)
In order to ensure that the water in each monitoring well after purging is representative of
the water in the aquifer, a minimum of three well volumes were removed. Groundwater
monitoring wells that did not generate three well volumes of water were bailed dry and then
given sufficient time to allow for recharging.All sampling tasks were completed within 24
hours of purging.
Groundwater samples obtained from groundwater monitoring wells MW-4, MW-7, MW-8,
MW-9, and MW-10 were collected using disposable polyethylene bailers and new nylon
rope.All groundwater samples collected from groundwater monitoring wells MW-4, MW-7,
MW-8, MW-9, and MW-10 were placed in laboratory-supplied containers and shipped on
wet ice to TestAmerica, Inc. in Nashville, Tennessee,for analysis of volatile organic I
compounds(VOCs)by Standard Method(SM)6200B.Additionally, groundwater samples
obtained from monitoring well MW-7 were placed in laboratory-supplied containers and
shipped on wet ice to TestAmerica, Inc. in Nashville, Tennessee,for analysis of ethylene
dibromide(EDB)by Environmental Protection Agency(EPA)Method 504.1.
Groundwater samples submitted for VOC analysis were placed in triplicate 40-milliliter(mL)
volatile organic analysis (VOA)glass vials with Teflon-lined septa screw caps preserved
with hydrochloric acid (HCI). Groundwater samples submitted for EDB analysis were
I collected in triplicate 40-mL VOA glass vials with Teflon-lined septa screw caps preserved
with sodium thiosulfate(Na2SO3). Laboratory analytical results and chain-of-custody
documentation are included as Appendix C.

The following are`permitted by rule"and do not require an individual permit when constructed in accordance
with the rules of 15A NCAC 02C.0200. This/orm shall be submitted at least 2 weeks prior to construction.
AQUIFER TEST WELLS(15A NCAC 02C.0227)
These wells are used to inject uncontaminated fluid into an aquifer to determine aquifer hydraulic characteristics.
IN SITU REMEDIATION(15A NCAC 02C.0225)or TRACER WELLS(15A NCAC 02C.0229):
1) Passive Injection Systems -In-well delivery systems to diffuse injectants into the subsurface. Examples include
ORC socks,iSOC systems,and other gas infusion methods.
2) Small-Scale Injection 0 nerations- Contaminant plumes located entirely within a land surface area not to
exceed 10,000 square feet. For tracer tests in uncontaminated areas the area of influence of the injection well(s)shall
be entirely within a land surface area not to exceed 10,000 square feet. An individual permit shall be required for
test or treatment areas exceeding 10,000 square feet.
3) Pilot Tests -Preliminary studies conducted for the purpose of evaluating the technical feasibility of a
remediation strategy in order to develop a full scale remediation plan for future implementation,and where the
surface area of the injection zone wells are located within an area that does not exceed five percent of the land
surface above the known extent of groundwater contamination. An individual permit shall be required to conduct
more than one pilot test on any separate groundwater contaminant plume.
4) Air Injection Wells-Used to inject ambient air to enhance in-situ treatment of soil or groundwater.

DWQ/UICIIn Situ Remed.Notification(Revised 4/26/2012) Page 2

DESCRIPTION OF PROPOSED INJECTION ACTIVITIES — Provide a brief narrative regarding the
purpose,scope,and goals of the proposed injection activity.
The purpose of the injection is to reduce benzene, 1.2-dichloroethane, and ethylene dibromide concentrations
in groundwater in the vicinity of monitoring wells MW-7, MW-8, and MW-11 to concentrations below the
GCL limits using in-situ chemical oxidation. Sodium persulfate and ferrous sulfate(persulfate activator) with
citric acid solutions will be infected into proposed infection wells INJ-1,INJ-2.and MW-4/INJ-3. The volume
of solution based on 0,10 mobile porosity is estimated to be 2,350 gallons into each well. The maximum
injection volume for each well based on 0.30 total mobile porosity is estimated to be 7.050 gallons. The actual
injection volume will ultimately be determined by the arrival of solution during infection at nearby observation
wells MW-7.MW-8.and MW-11 during the actual injection but will not exceed 7.050 gallons into each well.
J. INJECTANTS—Provide a MSDS and the following for each injectant.Attach additional sheets if necessary.
NOTE: Approved injectants (tracers and remediation additives) can be found online at
tvj/aus/gwpr.. All other substances must be reviewed by the Division of Public
Health,Department ofHealth and Human Services. Contact the UIC Program for more info(919-807-6496).
Injectant: sodium persulfate
Volume of injectant: Maximum 21,150 gallons(total for both iniectants

Underground injection Monitoring Plan
Former ExxonMobil Facility#42650
Burlington,Alamance County, North Carolina
Groundwater Incident#6416
After installation of the three new wells and before the injection,baseline samples will be taken from MW-
11, INJ-1 and INJ-2.Samples will be analyzed for volatile organic compounds(VOCs)by Standard
Method(SM)6200B, ethylene dibromide by Environmental Protection Agency(EPA)Method 504.1,
sulfate,and total and dissolved iron.
During the injection,two samples per day will be collected via bailers from the dose-response well
locations within the injection ROI(MW-7, MW-8, and MW-11)and monitored for field parameters(pH,
redox potential[ORP], conductivity,turbidity,temperature, and dissolved oxygen). Field screening of
persulfate using field test kits will also be conducted.
During the 1 a+month and the 1st and 2nd quarter after the injection event,ARCADIS will gage groundwater
monitoring and chemical injection wells associated with the site(MW-1, MW-2A, MW-3, MW-4/INJ-3,
MW-5,MW-6, MW-7, MW-8, MW-9, MW-10,MW-11, DW-1, DW-2, INJ-1 and INJ-2)and sample
monitoring wells MW-7, MW-8,and MW-11. Monitoring well samples will be analyzed for VOCs by
Standard Method(SM)620DB, ethylene dibromide by EPA Method 504.1,sulfate, and total and dissolved
iron.Field screening of persulfate using field test kits will also be conducted.
Monitoring wells to be sampled will be sampled utilizing a PROACTIVE SS Mega-Typhoon Pump&
control box with low flow groundwater sampling techniques to collect groundwater parameters and to
minimize turbidity during sample collection. Groundwater parameters including temperature,dissolved
oxygen(DO), pH,conductivity, oxidation reduction potential(ORP), and turbidity will be collected utilizing
an YSI 556 Multi-Probe System(MPS)and flow through cell. A turbidity reading will be collected before,
during,and after purging.When turbidity decreased to below 10 Nephelometric Turbidity Units(NTU),or
remains stable,a groundwater sample will be collected from the tubing. Groundwater samples collected
from the monitoring wells will be placed in laboratory-supplied containers and shipped to TestAmerica,
Inc. in Nashville,Tennessee. Following the completion of the above proposed remedial actions,
ARCADIS recommends that semi-annual monitoring and sampling be conducted for one year. The
monitoring and sampling of the wells will be used to further evaluate the effectiveness of the treatment
and subsequent actions.

with incompatible materials can result in a material
decomposition or other uncontrolled reactions.
HAZARDOUS DECOMPOSITION PRODUCTS: Oxygen that supports combustion and oxides of
sulfur.
COMMENTS: PRECAUTIONARY STATEMENT:Use of persulfates in chemical reactions
requires appropriate precautions and design considerations for pressure and thermal relief.
Decomposing persulfates will evolve large volumes of gas and/or vapor,can accelerate exponentially with
heat generation,and create significant and hazardous pressures if contained and not properly controlled or
mitigated.
Use with alcohols in the presence of water has been demonstrated to generate conditions that require
rigorous adherence to process safety methods and standards to prevent escalation to an uncontrolled
reaction.
