1. Injection Zone
The Former Rental Towel Uniform Services (RTUS)/National Services Industries, Inc. (NSI) facility (the Site) is
located at 610 Woody Drive, Graham, Alamance County, North Carolina (Figure 1).
The proposed enhanced reductive dechlorination (ERD) injection will be completed in accordance with Title 15A
North Carolina Administrative Code 02C .0225. The proposed injection locations are shown in Figure 2. Injections will
be completed at three downgradient barriers, including two onsite barriers and one off-site barrier each completed in
saprolite/partially weathered rock (PWR). Injections will occur in the barriers via permanent wells. The onsite eastern
barrier will include two 150-foot rows of permanent injection wells, the onsite southwestern barrier will include two
200-foot rows of permanent injection wells, and the offsite barrier will include two 100-foot rows of permanent
injection wells. Injections into the permanent wells will target a 20-foot interval in the shallow aquifer at a general
depth of 20-40 feet below ground surface (bgs). Figures 3 and 4 show the proposed injection locations with February
2020 tetrachloroethene (PCE) and trichloroethene (TCE) data for shallow wells, respectively. A cross section location
map is provided in Figure 5. Figure 6 presents a hydrogeologic cross-section that illustrates the interpreted water
table equipotential lines and PCE isoconcentrations at the Site with proposed eastern barrier injection locations.
Table 1 summarizes proposed injection intervals and well construction details, and Appendix A includes well
construction diagrams for the proposed permanent injection and monitoring wells.
2. Hydrogeologic Evaluation
2.1 Regional Geology and Hydrogeology
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 Carolina terrane of North Carolina (Brown, 1985). Bedrock in the area is described as
foliated to massive metamorphosed gabbro and diorite, and mafic metavolcanics (NCGS, 1985). Bedrock is typically
highly deformed with multiple fracture and foliation planes, and granitic intrusions are common. 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 o f the
parent rock (Heath, 1980). Saprolite represents the most extreme weathered condition of the parent bedrock from
which it is derived. A transitional zone of 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 is often highly fractured and permeable and contains fragments of
unweathered rock. Distinct zones of PWR are more frequent over metamorphosed bedrock than in massive
homogenous igneous rocks. 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 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 act 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. Hydraulic conductivity is typically higher in PWR relative to the overlying saprolite
and the bedrock below. Most water supply wells in this region tap the fractured bedrock unit.
2.2 Site Geology
Surface soils in some areas of the Site consist of a 1- to 5-feet thick layer of reddish-brown-tan clay to clayey sand
overburden. The overburden is underlain by a 20- to 30-feet thick saprolite layer that consists predominantly of silty-
sand but varies from silty clay to coarse-grained sand in certain areas of the Site. The saprolite layer is interbedded
with and underlain by a PWR layer. The PWR layer has an average thickness of 5- to 10-feet and is underlain by
fractured metamorphosed bedrock. PWR and bedrock are locally interlayered. Bedrock onsite is described as black

and white meta-volcanic rock. The bedrock surface mimics land surface topography and dips to the east and
southeast. Depth to bedrock ranges from 21 to 42 feet bgs onsite and decreases to approximately 10 feet bgs east of
Town Branch Creek. A cross section location map and cross sections with subsurface lithology are provided in
Figures 5 through 7.
2.3 Site Hydrogeology
In February 2020, onsite groundwater (within the Cintas property boundary) was encountered at depths ranging from
5.75 to 18.60 feet bgs. Offsite, depth to groundwater ranges from 3.77 to 23.60 feet bgs. Depth to water
measurements and groundwater elevations are summarized in Table 2. Potentiometric values and equipotential
contours for groundwater in the shallow and deep hydrogeologic units are presented in Figures 8 and 9, respectively.
Figure 6 presents a hydrogeologic cross-sections that illustrates the interpreted water table for the eastern portion of
the Site. Potentiometric data indicate that the Site is located on a groundwater divide with groundwater in the shallow
hydrostratigraphic unit flowing to the south, southeast, and east. Similar to the shallow groundwater flow, groundwater
in the bedrock aquifer is flowing to the south, southeast, and east. Groundwater flow patterns indicate that
groundwater in both hydrostratigraphic units flows towards the nearest surface water body. The site is situated
between Town Branch Creek, a tributary of the Haw River, to the east and Country Home Branch Creek, a tributary of
Town Branch Creek, to the west. Additionally, a southeast-northwest oriented unnamed tributary of Town Branch
Creek exists to the southeast of the Site.
2.3.1 Aquifer Parameters
Pneumatic slug tests were performed on two deep source area monitoring wells and traditional physical slug tests were
performed on two shallow source area monitoring wells. Details of aquifer test methods and results are presented in
the Source Area Investigation Report (Geosyntec, 2016). The hydraulic conductivity (K) for the water bearing zone (15-
35 feet) is variable, with estimates ranging from 0.02 to 0.15 foot per day (ft/day). Based on plume length, K values
are likely closer to 0.15 ft/d. These ranges are typical for silt.
3. Injectant Information
An ERD pilot test was performed at the Site in 2018 using a dilute Electron Donor Solution-Extended Release®
(EDS-ER®)/sodium bicarbonate/Nutrimens® solution. These materials were used with success during the pilot test
and no problems were identified following injection. Each proposed injectant is included on the NCDEQ list of
approved injectants (NCDEQ, 2017). The same materials will be used during the proposed full-scale barrier
injections.
3.1 Onsite Downgradient Injection Barriers
ERD injections will be administered in two onsite downgradient areas of the plume. A dilute (EDS-ER®/sodium
bicarbonate/Nutrimens® solution will be injected along the eastern and southwestern property lines, near EW-6 and
MW-11, respectively. To administer injections in the eastern barrier, eight permanent wells spaced approximately 50
feet apart would be installed along two 150-foot rows, coincident with the 700 micrograms per liter (µg/L) (1,000 times
the PCE remedial goal [0.7 µg/L]) PCE groundwater contour. To administer injections in the southwestern barrier, ten
permanent wells spaced approximately 50 feet apart would be installed along two 200-foot rows, coincident with the
700 µg/L PCE groundwater contour. Injections in the onsite barriers would target a 20-foot interval from approximately
10 to 30 feet bgs in the eastern barrier and 15 to 35 feet bgs in the southwestern barrier. Injection wells will be
installed on top of bedrock and screened in saprolite/PWR. The proposed onsite injection barrier locations are shown
in Figure 2, and proposed injection intervals are summarized in Table 1.
It is proposed that 22,000 gallons of a dilute EDS-ER®/sodium bicarbonate/Nutrimens® solution be injected into the
eastern barrier and 27,500 gallons of a dilute EDS-ER®/sodium bicarbonate/Nutrimens® solution be injected into the
southwestern barrier. The total injection volume assumes a radius of influence (ROI) of 15 feet and a pore volume
replacement of 24 percent of the effective pore volume. The ROI is assumed based on the pilot study injection
performed at the site, during which changes in field parameters were observed in a monitoring well 10 feet

downgradient of the injection well and similar, but less significant, changes were observed in a monitoring well 20 feet
downgradient.
Approximately 16,800 pounds of EDS-ER®, 15,200 pounds of sodium bicarbonate, and 40 gallons of Nutrimens® will
be injected into the onsite eastern barrier. Approximately 21,000 pounds of EDS-ER®, 19,000 pounds of sodium
bicarbonate, and 50 gallons of Nutrimens® will be injected into the onsite southwestern barrier. Injection make-up
water will be derived from an offsite fire hydrant owned by the City of Graham.
EDS-ER® will be injected to stimulate the formation of anaerobic conditions and provide an electron donor for
dehalorespiring bacteria. Sodium bicarbonate will be added as a neutralizing agent to limit decreases in the
groundwater pH during biodegradation of the carbon substrate and Nutrimens®, a reduced carbon fermentation
product, contains required cofactors utilized by dehalorespiring bacteria.
The injection amendments will be mixed above-ground in a batch process prior to subsurface delivery. Injection
make-up water will be delivered to the Site in a clean 4,000 gallon capacity tanker truck. Intermediate bulk container
(IBC) totes (300-gallon) will be connected to the tanker truck and the EDS-ER® and sodium bicarbonate will be mixed
in the IBC totes with water from the truck. Small batches will be mixed in the IBC tote and transferred to the tanker
truck. Once the EDS-ER® and sodium bicarbonate has been transferred to the tanker truck, the solution will be
recirculated within the tanker truck during the injection to keep the solution mixed. Once mixed, the solution will be
injected into the proposed permanent injection wells using a pneumatic double diaphragm pump. Proposed injection
quantities are summarized in Table 3. Materials safety data sheets for the injection amendments are included as
Appendix B.
3.2 Offsite Downgradient Injection Barrier
ERD injections will be administered in one offsite downgradient area of the plume. A dilute EDS-ER®/sodium
bicarbonate/Nutrimens® solution will be injected to the east of the Site, near MW-32. To administer injections in the
offsite barrier, six permanent wells spaced approximately 50 feet apart would be installed along two 100-foot rows,
coincident with the 700 µg/L PCE groundwater contour. Injections in the offsite barrier would target a 20-foot interval
from approximately 20 to 40 feet bgs. Injection wells will be installed on top of bedrock and screened in
saprolite/PWR. The proposed offsite injection barrier location is shown in Figure 2, and proposed injection intervals
are summarized in Table 1.
It is proposed that 16,500 gallons of a dilute EDS-ER®/sodium bicarbonate/Nutrimens® solution be injected into the
offsite barrier. The total injection volume assumes an ROI of 15 feet and a pore volume replacement of 24 percent of
the effective pore volume. The ROI is assumed based on the pilot study injection performed at the site, during which
changes in field parameters were observed in a monitoring well 10 feet downgradient of the injection well and similar,
but less significant, changes were observed in a monitoring well 20 feet downgradient.
Approximately 12,600 pounds of EDS-ER®, 11,400 pounds of sodium bicarbonate, and 30 gallons of Nutrimens® will
be injected. Injection make-up water will be derived from an offsite fire hydrant owned by the City of Graham.
EDS-ER® will be injected to stimulate the formation of anaerobic conditions and provide an electron donor for
dehalorespiring bacteria. Sodium bicarbonate will be added as a neutralizing agent to limit decreases in the
groundwater pH during biodegradation of the carbon substrate and Nutrimens®, a reduced carbon fermentation
product, contains required cofactors utilized by dehalorespiring bacteria.
The injection amendments will be mixed above-ground in a batch process prior to subsurface delivery. Injection
make-up water was delivered to the Site in a clean 4,000 gallon capacity tanker truck. IBC totes (300-gallon) will be
connected to the tanker truck and the EDS-ER® and sodium bicarbonate will be mixed in the IBC totes with water
from the truck. Small batches will be mixed in the IBC tote and transferred to the tanker truck. Once the EDS-ER®
and sodium bicarbonate has been transferred to the tanker truck, the solution will be recirculated within the tanker
truck during the injection to keep the solution mixed. Once mixed, the solution will be injected into the proposed
permanent injection wells using a pneumatic double diaphragm pump. Proposed injection quantities are summarized
in Table 3. Materials safety data sheets for the injection amendments are included as Appendix B.

3.3 Bioaugmentation
Bioaugmentation will be completed using the KB-1® bioaugmentation culture in each of the permanent injection
wells. The culture will contain an enriched dechlorinating culture, including Dehalococcoides ethenogenes bacteria
(DHC), capable of complete dechlorination of PCE and its daughter products. Groundwater data collected prior to the
pilot injection at the Site indicates that native dechlorinating cultures, especially DHC, were limited in some aquifer
zones. Therefore, bioaugmentation will be used to enhance the natural population of dechlorinating microbes in the
ERD treatment areas. Bioaugmentation injections will be performed at each of the proposed permanent barrier
injection wells. Following the ERD injection, and when optimal anaerobic conditions develop for bioaugmentation in
the injection areas, each location will receive 3 liters of bioaugmentation culture KB-1®. Prior to injecting the culture,
2 pounds of KB-1® primer will be injected at each well to further develop anaerobic conditions within the water and
limit inactivation of the KB-1® culture, which is highly sensitive to aerobic conditions. The bioaugmentation solution
will be injected using a double diaphragm pump.
4. Injection Procedure
The proposed permanent injection wells (described in Section 5) will be used to facilitate the proposed injections.
The proposed injection activities are estimated to take up to 40 days to complete, following well installation and
development. Injection rates are expected to range from approximately 1 to 5 gallons per minute via permanent well
and double diaphragm pump. Injection pressures are expected to be less than 50 pounds per square inch (psi) at
injection wells. However, the injection rate, amount and pressure will vary depending on field conditions.
5. Well Construction Details
The full-scale ERD field activities will include injection via permanent wells at two onsite barriers immediately
downgradient of the source area, and injection via permanent wells at one off-site barrier approximately 900 feet
downgradient of the source area. Proposed injection wells are shown on Figure 2, and proposed injection intervals
are summarized in Table 1.
Eight proposed permanent injection wells (IW-1 through IW-8) and ten proposed permanent injection wells (IW-9
through IW-18) will be installed to complete the onsite barriers to the east and southwest, respectively. Six proposed
permanent injection wells (IW-19 through IW-24) will be installed to complete the off-site barrier to the east. Eighteen
wells will be installed using a combination of hollow stem auger (HSA) and air rotary techniques, and six wells will be
installed using Rotosonic drilling techniques. Wells will be spaced approximately 50 feet apart and constructed of
schedule 40 polyvinyl chloride (PVC) with 20-foot 0.010-inch screen. Injection wells will be installed on top of
bedrock, and screened in saprolite/PWR. Proposed well construction diagrams are presented in Appendix A.
To evaluate downgradient injection performance, two shallow performance monitoring wells (PMW-4 and PMW-5) will
be installed at similar depths and screened intervals as the injection points/wells. The performance monitoring wells
will be installed using a combination of HSA and air rotary techniques. Performance monitoring wells will be
completed as 2-inch PVC with 10 feet of 0.010-inch well screen. Proposed well construction diagrams are provided in
Appendix A.
Prior to performing any invasive work, utilities will be marked by a private utility locator and surrounding public utilities
will be marked by a public utility locating service via 811 ticket. Additionally, each location will be pre-cleared using a
stainless-steel hand auger to a depth of at least 5 feet bgs. AECOM will complete and submit the necessary
documents to obtain access to install off-site injection and monitoring wells. Solid and liquid investigative derived
waste will be placed in drums, sampled, and properly manifested and transported off-site for disposal.
6. Monitoring Plan
Prior to injection, new injection wells, and existing and new monitoring wells will be purged and sampled to establish
baseline conditions. The sampling parameters to be analyzed during the baseline sampling event and post-injection

sampling will follow the tentative schedule/parameter list presented in Table 4. Proposed injection well construction
details are summarized in Table 1 and existing well construction details are summarized in Table 5. Sampling
frequency and parameters may be modified during the injection performance monitoring, based on interpretation of
the results.
7. Well Data Tabulation
See Table 5 for existing well construction details and Table 1 for proposed injection wells and DPT locations details.

Section 7: Precautions for Safe Handling and Use

ENVIRONMENTAL PRECAUTIONS: Where large spills are possible, a comprehensive spill response
plan should be developed and implemented.

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Wear appropriate respiratory
protection and protective clothing as described in section VIII. Depending on quantity of spill: (a) Small
spill - add solid adsorbent, shovel into disposable container and wash the area. Clean area with
detergent. (b) Large spill - Squeegee or pump into holding container. Clean area with detergent. In the
event of an uncontrolled release of this material, the user should determine if this release is reportable
under applicable laws and regulations.

WASTE DISPOSAL METHOD: All recovered material should be packaged, labeled, transported, and
disposed or reclaimed in accordance with local, state, and federal regulations and good engineering
practices.

Section 8: Control Measures

RESPIRATORY PROTECTION: Not normally needed. A qualified health specialist should evaluate
whether there is a need for respiratory protection under specific conditions.

VENTILATION: Handle in the presence of adequate ventilation. Intermittent clean air exchanges
recommended, but not required.

Spilled KB-1® should be soaked up with sorbant and saturated with a 10% bleach solution (prepared by
making a one in ten dilution of diluted standard bleach [normally sold at a strength of 5.25% sodium
hypochlorite] to disinfect affected surfaces. Sorbant should be double bagged and disposed of as
indicated in section 12. After removal of sorbant, area should be washed with 10% bleach solution to
disinfect. If liquid from the culture vessel is present on the fittings, non-designated tubing or exterior of the
stainless steel pressure vessel liquid should be wiped off and the area washed with 10% bleach solution.

Section 7 - Handling and Storage
KB-1® is shipped in stainless steel pressure vessels and connected to injection lines and inert gas is used
to pressurize the vessel to displace the contents. KB-1® should be handled with care to avoid any
spillage. Vessels are shipped with 1 pound per square inch (psi) pressure; valves should not be opened
until connections to appropriate lines for subsurface injection are in place.
Storage Requirements: Avoid exposing stainless steel pressure vessels to undue temperature
extremes (i.e., temperatures less than 0°C or greater than 30°C may result in harm to the microbial
cultures and damage to the vessels). All valves should be in the closed position when the vessel is not
pressurized or not in use to prevent the escape of gases and to maintain anaerobic conditions in the
vessel. Avoid exposure of the culture to air as the presence of oxygen will kill dechlorinating
microorganisms.
