1 Injection Zone
The injection zone will consist of the immediate vicinity of existing wells MW-1, DW-2, MW-6R, MW-8,
MW-9, MW-10, MW-11, MW-13, DW-16 and DW-19 as well as injection wells IW-8, IW-9, IW-11, IW-12,
IW-13, IW-14, IW-15 and IW-16. The monitoring wells are screened from approximately 8.46 feet to 54.80
feet below ground surface. The injection wells are screened from the top of the water table to the bed
rock surface. Monitoring well construction details are summarized in Table 1. Existing injection well
construction details are summarized in Table 2.
2 Hydrology Description
A. The site is located in the Carolina Slate Belt of the Piedmont Physiographic Province of North
Carolina. The surficial geology consists of residual soil which has formed from the in -place
chemical and physical weathering of the underlying bedrock. The surrounding topography
consists of rolling land and broad ridges. According to the Geologic Map of North Carolina, the
regional bedrock generally consists of metamorphosed rock meta gabbro, metadiorite and
plutonoic-volcanic complexes. Groundwater generally flows to the southeast discharging into
tributaries of Salem Creek.
Based on cross sections in the UIC Permit Application — Class 51 Wells, the subsurface soils were
silty sand south and northwest of the onsite build, from the surface to 25 feet Beneath the onsite
building consisted of fill material to approximately 6 feet followed by silty sand, sandy silts, and
clayey silt to 45 feet. Subsequent investigation confirmed residual soil texture ranged from
predominantly decomposed rock (saprolite) and fine grained sandy silts and clays. Soil extends to
depths ranging from approximately 2 to 45 feet below ground surface.
According to the USGS Topographic Map, Winston-Salem West, North Carolina Quadrangle
(Figure 1), tributary to Salem Creek is located south of the site and flows into Salem Creek
southeast of the site. Groundwater at the site was encountered at depths ranging from 14.26 to
22.22 below ground surface. Based on the water level measurements from the September 15,
2022 shallow groundwater flow direction at the site is generally to the southeast.
B. Based on the soil boring logs and monitoring well logs silty SANDS were observed in the southern
and northern borders of the site. The center of the site consisted of fill material to approximately
6 feet followed by silty sand, sandy silts, and clayey silt to 45 feet.
C. Depth to bedrock at the site is approximately 45 feet below ground surface.
D. Depth to mean seasonal high water table on average occurs in March, the mean elevation below
ground surface ranges from 14.12 to 21.76 across the site.
E&F. A low permeability, water -table aquifer is present beneath the site. This water -table aquifer is
recharged primarily by precipitation events. Static water level measurements collected on
September 15, 2022 are summarized in Table 1. Potentiometric surface maps produced with the
September 15, 2022, water level data shows that groundwater in the surficial aquifer flows
generally towards the southeast (Figure 5). The horizontal hydraulic gradient calculated between
monitoring wells MW-3 and MW-7 with September 15, 2022 groundwater measurements was
0.02. Foot/foot. Aquifer testing performed at monitoring wells MW-1 and MW-5 on October 9,
1998 indicated that the surface aquifer has an average hydraulic conductivity of 1.19 feet per day.
The hydraulic conductivity value was used to calculate the average linear horizontal groundwater
11.990015.00 1 May 2023

velocity at the site. Using the value of 1.19 feet/day for the hydraulic conductivity, the horizontal
gradient for 0.02 foot/foot calculated between monitoring wells MW-3 and MW-7, and an
estimated effective porosity of 0.30, the average linear horizontal groundwater velocity was
calculated to be 0.09 feet/day.
G. Lithostratigraphic and hydrostratigraphic logs were not used.
3 Injection Information
A A Material Safety Data Sheet for Potassium Permanganate (KMnO4) provided by Dawn SCI is
attached. This product has been previously reviewed and approved by the UIC Program for
injection. KMnO4 will be mixed with municipal water at a ratio of 10 parts water to 1 part KMnO4.
B Municipal water from the City of Winston-Salem distribution system will be used to dilute the
KMnO4 as well as chase the injectant with one to two injectant volumes of water.
C Diluted solution to potassium permanganate will be used to reduce the concentration of
perchloroethene (PCE) in the groundwater. Permanganate has been used for wastewater and
drinking water treatment for many years. In contrast, permanganate has been used for
groundwater remediation for less than 20 years.
Based on this stochiometry, 1.81 gram (g) of permanganate is needed to degrade 1 g of TCE,
releasing 1.32 g of manganese dioxide, 0.67 g of carbon dioxide and 0.81 g of chlorine.
Potassium permanganate (KMnO4) and sodium permanganate (NaMnO4) have been injected at
hundreds of sites to chemically oxidize chlorinated solvents and other ground water
contaminants. In this process, a permanganate (MnO4) solution is injected into the subsurface
using temporary points or permanent wells. Once injected, the MnO4 is transported through the
aquifer by ambient or induced groundwater flow.
When permanganate is injected into the subsurface, a portion of the material reacts with the
target contaminant and a portion reacts with the aquifer material. The amount of permanganate
that reacts with non -target chemicals is often referred to as the natural oxidant demand (NOD).
When estimating the required amount of reagent to inject, designers must account for both
permanganate consumed by the target chemicals and the NOD. If the NOD is not considered, the
permanganate will be depleted more rapidly than expected and treatment efficiency may be less
than desired.
EnviroTrac will inject a 10% solution of potassium permanganate to eleven of the existing
monitoring wells at the property. Monitoring wells included in the initial treatment will include:
monitoring wells MW-1, DW-2, MW-6R, MW-8, MW-9, MW-10, MW-11, MW-13, DW-16 and DW-
19 as well as injection wells IW-8, IW-9, IW-11, IW-12, IW-13, IW-14, IW-15 and IW-16.
Application rates and treatment volumes will be recorded for each monitoring well.
D Recent work has shown permanganate to be an effective oxidant for treatment of chlorinated
solvents (PCE and trichloroethene {TCE}) and aromatic hydrocarbon (naphthalene, phenanthrene,
11.990015.00 2 May 2023

pyrene and phenols). Representative reactions illustrating the oxidation of PCE (C2C14) and TCE
(C2HC13) by permanganate are shown below.
C204 + 1 1/3 MnO4 1/3 Mn02 + 2 CO2 + 2 2/3 H + 4 Cl (PCE)
C2HC13 + 2 MnO4 2 MnO2 + 2 COz + H + 3 CI (TCE)
E No site -specific testing or modeling has been performed.
F Development of byproducts is not anticipated at the site.
4 Injection Procedure
Following approval of the injection strategy, EnviroTrac will order 440 pounds of KMnO4 to be
shipped to the site. A sample of the municipal water has previously been collected from the
facility and analyzed for volatile organic compounds (VOCs) by Standard Method 6200B. The
municipal water supply was free of VOCs and suitable for use in the injection strategy.
EnviroTrac will mix KMnO4 and municipal water from the City of Winston-Salem distribution
system in a container with wheels and a hose connection at the base. The 5 percent KMnO4
solution will be gravity fed into each of the ten monitoring wells and eight injection wells. Once
the KMnO4 solution has been injected into each monitoring and injection well, municipal water
from the City of Winston-Salem distribution system will be used to chase the injectant with one
to two injectant volumes.
(A) The average rate of injection at any locations is anticipated to range between 0.25 and
1.0 gallons per minute. The maximum daily rate of injection will be limited to one injection
solution volume (138 gallons per day).
(B) The head created by the elevation of the liquid above the water table will range from 5
to 10 pounds per square inch.
