1 . Injection Zone
A site location map is provided as Figure 1.The map shows the proposed injection zone as stipulated in Title 15A
North Carolina Administrative Code 02C.0225(e)(2)and includes an outline of the proposed groundwater monitoring
area is shown on Figure 2.The active injections will take place in an area of up to approximately 5,500 square feet.
The injections are proposed to be completed from approximately 9 feet below ground surface(bgs)to 35 feet bgs in
the saprolite within the vicinity of monitoring well MW-11.The injection zone also includes a sorptive barrier
downgradient of the injection area.
2. Hydrogeologic Evaluation
2.1 Regional Geology and Hydrology
The Site is located in the Piedmont physiographic province. Both the regional and local landscape of the area is
characterized by broad,gently rolling uplands and moderate to steep slopes common to the Piedmont. Geologically,
the Site is located in the Milton Belt litho-tectonic province of North Carolina(Brown, 1985). Bedrock in this province
is described as a metamorphic complex consisting of biotite gneiss and schist interlayered with mica, amphibolite,
and granitic masses. Rocks of these compositions weather to form several distinct lithologic zones. Overlying the
competent bedrock are unconsolidated, granular, and porous materials(regolith)that may consist of alluvial deposits,
soils, and residual material formed from in-situ physical and chemical weathering of the parent bedrock.The portion
of the regolith that is derived from weathered rock, commonly referred to as saprolite, retains much of the relic fabric,
texture, and structures of the parent rock(Heath, 1989).
Saprolite represents the most extreme weathered condition of the parent bedrock from which it is derived.A
transitional zone of partially weathered rock(PWR)is typically found between the saprolite zone and the lower
competent bedrock. PWR is typically friable bedrock that retains the parent rock structure, but it has undergone less
weathering than saprolite.The transitional zone PWR often is highly fractured and permeable and contains fragments
of unweathered rock. Bedrock in this region typically has decreasing fracture density with depth(Heath, 1989).
Groundwater aquifer systems in this part of the Piedmont region correspond with the either unconsolidated porous
media or fractured, crystalline bedrock.The porous saprolite media typically represents the unconfined or"water
table" hydrostratigraphic unit of the regional aquifer. Saprolite and PWR acts as a storage reservoir for groundwater
that feeds the underlying fractured bedrock hydrostratigraphic unit. PWR and bedrock units can exhibit unconfined,
semi-confined,or even confined hydraulic behavior. Most water supply wells in this region tap the fractured bedrock
unit. Supply wells installed in the bedrock aquifer of this region typically yield between 15 and 20 gallons per minute
(gpm) (Daniel and Payne, 1990).
In groundwater recharge areas of the Piedmont, the water table is usually closer to the ground surface during the
winter and spring months and is typically deeper during the drier summer and autumn months. In the Piedmont,
shallow groundwater generally flows away from the higher elevation recharge areas and discharges to the stream
valleys at lower elevations.
2.2 Site Geology
The Site is underlain by varying thicknesses of fine-grained saprolite that overlays a fractured,felsic schist bedrock.
Soils(i.e., residuum)and saprolite at the Site are generally described as mottled orange/brown/gray micaceous
sandy silt and clayey silt.The residual soil and saprolite unit is very thin on the northeast portion of the Site,where
competent bedrock was encountered at a depth of 7 feet bgs at monitoring well MW01d.The saprolite unit thickens
toward the western portion of the Site(ENVIRON, 2000;AECOM Technical Services of North Carolina, Inc.
[AECOM], 2012).
Depth to competent bedrock within the Cintas property boundary varies from approximately 7 feet bgs at monitoring
well MW01d to 56 feet bgs at monitoring well MWO4d(ENVIRON, 2000). Depth to competent bedrock on off-site

Modification—Attachments
properties investigated during the Remedial Investigation ranges from 40 feet bgs at wells MW10d and MW14d to
100 feet bgs at well MW08d.
In the Piedmont region the surface of competent bedrock often has a localized undulating pattern. On the Champion
property southwest of the Cintas property the bedrock generally slopes in the western direction. In the area of the
proposed injections near MW-11 the bedrock surface elevation is approximately 835 feet mean sea level (msl).The
deepest extent of the saprolite zone that is targeted by these injections ranges approximately from 845 feet msl to
855 ft msl.
2.3 Site Hydrogeology
Within the Cintas property boundary, groundwater is encountered at depths ranging from 12 to 28 feet bgs and the
water table surface is found primarily in the saprolite hydrostratigraphic unit.On the east and northeast sections of
the Cintas property,the saprolite unit is not saturated due to very shallow bedrock in these areas.Within the
Champion property boundary, groundwater is encountered at depths ranging from 7 to 14 feet bgs and the water
table surface is found within the saprolite hydrostratigraphic unit.
Potentiometric elevations for shallow wells on the Champion property ranged from 873.71 to 868.59 feet msl during
the most recent monitoring event in March 2018.The general groundwater flow on the Site is generally to the
south/southeast towards Leak Fork Creek.The water level gauging data from the March 2018 monitoring event were
used to produce the groundwater potentiometric map shown in Figure 3 for the Saprolite hydrostratigraphic unit.
Using the March 2018 data for wells ART-02 and MW-11,the general hydraulic gradient of the site is calculated to be
0.027 feet per foot. Using the March 2018 data for wells PMW-3 and MW-11,the hydraulic gradient of the Champion
property injection area is calculated to be 0.020 feet per foot.
While aquifer tests have not been performed at the Site, several tests were conducted at a nearby site.The
analogous site is located approximately 1.5 miles away. Slug Tests were conducted on both sites in monitoring wells
that were screened in similar lithologies to the Saprolite unit logged at the Former Rental Uniform Service facility
(sandy silt or clayey silt).
At the nearby site, rising head permeability tests within the shallow Saprolite layer, a sandy silt, resulted in K values
ranging from 4.45x10-4 centimeters per second(cm/s)to 5.92x10-4 cm/s(or 1.26 to 1.68 feet per day).The results of
the slug testing correspond to a moderate silty sand and lithologic borings recorded at both sites that indicate
saprolitic textures/Saprolite similar to the unit that will be affected by the proposed injection.
3. Injectant Information
In this modification AECOM proposes to inject AquaZVI®(an aqueous suspension of colloidal zero valent iron [ZVI])
upgradient of Leak Fork Creek within the MW-11 hot spot area.AquaZVI®contains 40% colloidal ZVI with particles
less than 5 micrometers(pm) in diameter. AECOM plans to inject 18,000 pounds(1,348 gallons)of AquaZVl°as a
6% by volume suspension (a total injected volume of approximately 23,650 gallons when mixed with water for
injections).AquaZVI®stimulates chemical reduction processes and dechlorinates tetrachloroethene(PCE)and its
daughter products.
PlumeStopTM will be injected to install a sorptive barrier. PlumeStopTM consists of 75%water, less than 25% colloidal
activated carbon that is less than 2.5 pm, and proprietary additives.AECOM plans to inject 9,600 pounds(1,136
gallons)of PlumeStopTM as an aqueous suspension that is approximately 6.6% PlumeStopTM by volume(a total
injected volume of approximately 17,050 gallons when mixed with water for injections). The purpose of PlumeStopTM
is to reduce the concentration of dissolved chlorinated volatile organic compounds(CVOCs)downgradient of the
AquaZVI®injections through adsorption onto activated carbon.The PlumeStopTM barrier is intended to work in
combination with the AquaZVl®to quickly and permanently reduce CVOC mass flux into the nearby Leak Fork Creek.
An Oxygen Release Compound(ORC®)barrier will be installed between Leak Fork Creek and the sorptive barrier.
ORC®is comprised of 60-70% magnesium hydroxide, 30-40% magnesium peroxide, less than 3% dipotassium
phosphate, less than 3%monopotassium phosphate, and less than 1% magnesium oxide.The ORC®barrier exists to
provide dissolved oxygen to treated groundwater before entering the creek.Approximately 1,600 pounds of ORC®will

Modification—Attachments
be mixed with water to create approximately 650 gallons of a 25%ORC®slurry.The material safety data sheets for
AquaZVl®, PlumeStopTM, and ORC®are included in Appendix A. Municipal water will be used for dilution for the
proposed injection concentrations.
ZVI, PlumeStopTM and ORC®have previously been piloted at the site within the same aquifer during the Phase II and
Phase III injection activities and were detailed in the Phase II/III Preconstruction Report(AECOM,2015)and Phase
II/III Construction Completion Report(AECOM, 2016). Small scale injections of PlumeStopTM and ORC®,ZVM(zero
valent iron(ZVI)and aluminum-based products(Z-Loy TM and Z-LoyTM LA))were completed under NCDEQ DWR UIC
permit numbers W10400384&W10400367.The goal of the PlumeStopTM and ORC®injections was to decrease VOC
concentrations in surface water of Leak Fork Creek downgradient of the Site(immediately downgradient of the MW-
10 cluster). The primary goal of the ZVM injections was to reduce the concentrations of PCE in the vicinity of the MW-
03 hotspot,which is was an upgradient source of contaminant flux to the PlumeStopTM application area. Following the
injections, concentrations of PCE and its daughter products decreased in the vicinity of MW-03 and in the porewater
and surface water samples collected in Leak Fork Creek downgradient of the injection area.
The injections described above are proposed for treatment of the target zone with dimensions of approximately 5,500
square feet in area and up to 25 feet in thickness within the Champion parking lot near monitoring well MW-11.
Assuming an effective porosity of approximately 20%,the proposed injection volume represents approximately a 10%
displacement. Vendor assumptions are included in Appendix B.
4. Injection Procedure
Table 1 summarizes the injection plan. Figure 4 shows the proposed injection locations.There will be three different
injection phases during this proposed injection plan: a phase to inject AquaZVl®, a phase to inject PlumeStopTM and
a phase to inject ORC.AECOM estimates the three injection phases will take approximately 30 days to complete.All
three injection phases will be completed using direct push technology(DPT)injection methods.The injection flow
rates are expected to range from 0.1 to 10 gpm. It is expected that the injection pressure will be approximately 50
pounds per square inch gage(psig). However,the injection rate, amount and pressure will vary depending on field
conditions.
5. Fracturing Plan
A fracture plan is not needed as there will be no fracturing during these phases.
6. Well Construction Details
Approximately seventy-six DPT injection points are being proposed for this scope.Table 2 summarizes the proposed
construction details for the temporary DPT points.The points will be advanced up to 35 feet bgs depending on the
inferred thickness of the saprolite at the planned locations.Additional borings may be added within the general
injection area to achieve distribution of the proposed injection reagents at the intended depth, if necessary.
Additionally, up to three pore water wells will be installed on site.The porewater wells will be stainless steel push
samplers that placed into the Leak Fork Creek sediments immediately adjacent to the injection zone for monitoring.
Locations of the porewater wells will be determined at a future date.
7. Monitoring Plan
The primary contaminant on-site is PCE. Prior to the injections,AECOM will complete a site-wide groundwater
monitoring event within the 60 days prior to the injections that will serve as the baseline monitoring event for the
proposed injection activities.AECOM also proposes to conduct four quarterly performance groundwater monitoring
events to evaluate injection effectiveness. Finally, a larger sampling event will occur one year after the injection
program that will provide a more comprehensive evaluation of all Phase IV activities. Details of these events are
summarized in Table 3.
