CORRECTIVE ACTION EVALUATION REPORT
Town of Kernersville Landfill
NCDEQ SWS Permit # 34-04
EXECUTIVE SUMMARY
On behalf of the Town of Kernersville, North Carolina, WithersRavenel (WR) prepared this
Corrective Action Evaluation Report (CAER) for the Town of Kernersville Landfill. The Kernersville
Landfill is regulated under §.0500 of the North Carolina Solid Waste Management Rules
(NCSWMR). This CAER has been prepared in accordance with those rules.
In a letter dated July 16, 2013, the North Carolina Department of Environment and Natural
Resource, now doing business as the North Carolina Department of Environmental Quality
(NCDEQ), in response to the Groundwater Protection Standard (GPS) exceedances of volatile
organic compounds (VOCs) in groundwater monitoring wells at the facility, called for the Town to
select a remedy and submit a Corrective Action Application In July 2014, the Town submitted the
Corrective Action Application, selecting Monitored Natural Attenuation (MNA) plus
Phytoremediation as the remedy. The remedy was approved by NCDEQ-Solid Waste Section
(Section) in a letter dated July 23, 2014. The Town submitted a Corrective Action Plan (CAP) in
October 2014 and the Section approved the CAP in a letter dated November 4, 2014.
At the request of the Section, the Town's environmental consultant at the time, Joyce Engineering
(JOYCE), submitted a Corrective Action Evaluation Report (CAER) in October 2016 in accordance with
the Section's Guidelines for Corrective Action Evaluation Reports. In their Conclusions and
Recommendations, JOYCE recommended removing several of the MNA parameters from the
parameter list for the site and reducing the frequency of MNA monitoring to twice per CAER period,
during the two semiannual events immediately prior to the next, and subsequent, CAERs.
In a response letter (DIN27098) to the Town dated December 6, 2016, the Section approved the
request to remove cis-1,2-dicholorethylene from the COC list. However, the request to modify the
MNA monitoring frequency for the requested MNA parameters was not approved but changed to
continually monitoring them semi-annually (both sampling events) every three years.
In their report, Joyce concluded that:
• MNA plus phytoremediation remained an appropriate and effective remedy and no changes
to the CAP were recommended at the time.
• MNA plus phytoremediation remained an appropriate and effective remedy and no
contingency remedies were recommended at the time.
• There was no evidence that the contaminant plume had impacted the surface water in the
creek or that the plume had migrated off site.
• The current COC plume was reported as stable and concentrations of most COCs
appeared to be decreasing; and
• There was no need to impose land use restrictions on the landfill or adjoining property
at the time.

This report presents the second CAER for the facility and includes historical data and comments
recommendations previously reported by JOYCE, and subsequent sampling events conducted by
WR between September 2017 and July 2021 (referred to in this report as the "recent sampling
period"). Unless modified by the Section, subsequent CAERs will be submitted approximately every
five years.
Since October 2016, several of the constituents of concern (COCs) for the facility listed in the initial
CAER have not been detected during the semi-annual water quality sampling events. The current
list of COCs include the following VOCs: benzene, 1,1- dichloroethane (1,1-DCA), 1,2-
dichlorethane (1,2-DCA), 1,2-dichloropropane (1,2-DCP), and vinyl chloride (VC).
During the July 2021 groundwater sampling event low concentrations of four volatile organic
compounds (VOCs) in addition to VC were identified in the groundwater sample from MW-2R.
These included benzene (3.07 ug/L), 1,1 dichloroethane (1,1 DCA 9.24 ug/L), 1,2 dichloroethane
(1,2 DCA 0.520 ug/L), and 1,2 dichloropropane (1,2 DCP 3.64 ug/L). Measurement of dissolved
oxygen in the groundwater from MW-2R at the time of sampling was approximately 2.85 mg/L,
which indicates the presence of aerobic conditions. Because benzene and vinyl chloride are known
to be amenable to aerobic biodegradation, the EPA BIOSCREEN Natural Attenuation Decision
Support System model was used to predict future concentrations of the four VOCs downgradient
of MW-2R at a time ten years from the present.
Due to the relatively low concentrations of VOCs in the July 2021 sample from MW-2R, and the
slow rate of groundwater flow at the site, the BIOSCREEN runs predict that even under no
degradation conditions, detectable concentrations of the VOCs should not be present in
groundwater 25 to 50 feet downgradient of MW-2R within a ten-year period. Future monitoring
of VOC concentrations in samples from MW-2R and within surface water samples from location
SW-3, which is immediately downgradient of MW-2R can be used to evaluate the validity of the
BIOSCREEN model predictions.
This CAER presents plume maps and trend charts for each of the COCs. There is no evidence
that the plume is expanding horizontally or vertically, and constituent concentrations are
generally decreasing. TWR concludes that the current remedy is sufficient for remediating the
groundwater at the Kernersville Landfill facility and recommends no changes to the CAP or the
active remedy at this time.

1.0 INTRODUCTION
On behalf of the Town of Kernersville, WithersRavenel (WR) has prepared this Corrective
Action Evaluation Report (CAER) for the Town of Kernersville Landfill Facility (facility). This
CAER has been prepared in accordance with 15A NCAC 1313.1636 of the North Carolina
Solid Waste Management Rules (NCSWMR) and in response to Groundwater Protection
Standard (GPS) exceedances of several volatile organic compounds (VOCs) detected in
groundwater monitoring wells at the facility.
1.1 Site Background
The Town of Kernersville Landfill is a closed, unlined municipal solid waste landfill located on
approximately 58.2 acres which straddle Forsyth and Guilford Counties, NC, approximately 10
miles north of the Town of Kernersville. The waste disposal area comprises approximately 13.8
acres. Figure 1, General Location Map illustrates the general location of the landfill on top of a
7.5-minute United States Geologic Survey (USGS) topographic map for the Belews Creek, North
Carolina Quadrangle (Quad). The facility was issued a Permit to Operate by the North Carolina
Department of Waste Management (DWM), Solid Waste Section (Section) on May 15, 1985,
and a Letter of Closure on December 10, 1991.
The landfill is zoned residential/agricultural and is bounded on the east and west by open fields
and woodlands. The landfill is bounded on the north by property owned by Waste Management
and farther north by Freeman Road, and on the south by an unnamed tributary of Belews Creek.
Figure 2, Water Quality Sampling Locations Map illustrates the property boundaries, waste
disposal boundaries, monitoring well locations, and surface water sample locations.
The Town of Kernersville Landfill is currently monitoring groundwater in accordance with
criteria set forth in Title 15A Subchapter 13B .0500 of the North Carolina Solid Waste
Management Rules (NCSWMR) for municipal solid waste landfills (MSWLF) closed prior to
October 9, 1993. The current groundwater compliance monitoring network includes six
monitoring wells, comprised of one upgradient well and five downgradient wells. There is
relatively limited historical geological data available for the Kernersville landfill. Neither WR
nor the previous consultant (Joyce Engineering (JOYCE) could locate drilling records or boring
logs for wells on the property through a review of both the Town of Kernersville records and
NCDEQ records.
Existing monitoring well MW-6 serves as the background well for the facility. Monitoring well
MW-6 replaced MW-1 as the facility's background well due to infrequent opportunities to
sample the well because of low well volumes or the well-being dry; however, MW-6 has also
been dry during the last several sampling events. Downgradient monitoring wells MW-2, MW-
3S, MW-3D, MW-4, and MW-5 are monitored as part of the compliance network for the
facility. MW-1 is monitored for water levels only, as conditions permit. Monitoring well
construction details are summarized in Table 1, and the well locations are shown on Figure 2
These wells are summarized below, along with their current monitoring program status.

Groundwater samples are collected semiannually during the second and fourth quarters and
analyzed for constituents listed in the NC Solid Waste Section Environmental Monitoring
Appendix I/Appendix II list (in reference to 40 CFR Part 258 Appendix I and Appendix II). As a
condition of the CAP, monitoring wells MW-2, MW-3S, MW-3D, MW-4 and MW-6 are also
monitored for Monitored Natural Attenuation (MNA) laboratory constituents, including nitrate,
sulfate, chloride, alkalinity, total organic carbon, methane, ethane, ethene, volatile fatty acids,
dissolved hydrogen, biological oxygen demand, and chemical oxygen demand, as well as several
MNA field parameters, during both semiannual sampling events.
Based on the presence of constituents detected at concentrations above the North Carolina
Groundwater Quality Standards as listed in 15A NCAC 2L (the "21- Standards") that could
potentially be crossing the facility boundary, the North Carolina Department of Environment
and Natural Resources (NCDENR) requested that Kernersville submit a Groundwater
Assessment Plan to evaluate site conditions as they relate to groundwater quality. JOYCE
submitted a Groundwater Assessment Report to NCDENR on May 13, 2013. JOYCE, in their
Report, concluded that, based on site hydrogeology, it is unlikely that the site impacts reported
above the 2L Standards are crossing the property boundary.
In a July 16, 2013, response to the Groundwater Assessment Report, NCDENR determined
that the detection of VOCs at concentrations that exceeded the 2L Standards constituted a
violation of Section regulations. As required by NCDENR, JOYCE submitted a Corrective
Action Plan (CAP) on behalf of the Town of Kernersville Landfill in October 2014. NCDENR
approved the Corrective Action Plan in a letter dated November 4, 2014. It should be noted that
NCDENR is currently operating as the North Carolina Department of Environmental Quality
(NCDEQ).
At the request of the Section, JOYCE submitted a Corrective Action Evaluation Report (CAER) in
October 2016 in accordance with the Section's Guidelines for Corrective Action Evaluation Reports.
In their Conclusions and Recommendations, JOYCE concluded and recommended the following:
• Cis-1,2-dichloroethylene had not been detected in exceedance of its GPS in any
monitoring well since November 2012, and the concentrations of cis-1,2-
dichloroethylene appear to be stable or decreasing in all wells. JOYCE recommended
that cis-1,2-dichloroethylene be removed from the facility's COC list. No other changes
to the COC list were recommended at that time.

Several of the extended MNA parameters listed in the MNA listing demonstrated limited
usefulness in evaluating natural attenuation at this site. JOYCE recommended and
requested that BOD and COD be removed from the MNA analytical requirements for
this facility.
JOYCE also recommended and requested reducing the frequency of MNA monitoring to twice
per CAER period, during the two semiannual events immediately prior to the next, and
subsequent, CAERs for the following MNA parameters:
• Methane, ethane, and ethene
• Dissolved CO2
• Volatile Fatty Acids
• Ferrous Iron Wee+)
In a response letter (DIN27098) to the Town dated December 6, 2016, the Section approved
the request to remove cis-1,2-dicholorethylene from the COC list. However, the request to
modify the MNA monitoring frequency for the above -listed MNA parameters was not approved
but changed to continually monitoring them semi-annually (both sampling events) every three
years.
JOYCE concluded that MNA plus phytoremediation remained an appropriate and
effective remedy and no changes to the CAP were recommended at the time.
• JOYCE concluded that MNA plus phytoremediation remained an appropriate and
effective remedy and no contingency remedies were recommended at the time.
JOYCE concluded that there was no evidence that the contaminant plume had impacted
the surface water in the creek or that the plume had migrated off site. The current
COC plume was reported as stable and concentrations of most COCs appeared to be
decreasing. JOYCE concluded that there was no need to impose land use restrictions
on the landfill or adjoining property at the time.
This report presents the second CAER for the facility and includes historical data and comments
previously reported by JOYCE, and subsequent sampling events conducted by WR between
September 2017 and July 2021(referred to in this report as the "recent sampling period"). Unless
modified by the Section, subsequent CAERs will be submitted approximately every five years.

1.2 Aquifer Characteristics
The Town of Kernersville Landfill is located in the Piedmont Physiographic Province (Piedmont)
of North Carolina and is underlain by intrusive granitic rocks of Pennsylvanian -to -Permian age,
which are part of the Charlotte Belt Geologic Unit. The uppermost aquifer is unconfined and
includes both saprolite and fractured bedrock, which are well-connected. Groundwater at the
site has historically been reported flowing generally to the southwest.
JOYCE conducted hydraulic conductivity testing in November 2013 and, using the modified
Darcy equation (V=Ki/n), reported the following:
• Hydraulic gradient (i) is 0.04 ft/ft.
• An effective porosity value (n) of 30 percent was estimated.
• Hydraulic conductivity (K) 1.73 ft/day: and
• The calculated groundwater flow rate averaged approximately 0.20 ft/day.
As reported by JOYCE and confirmed by WR, the water table under the area of investigation is
typically encountered in the unconfined aquifer that is located mostly in saprolite but is believed
to grade into highly fractured bedrock with depth. Groundwater in the saprolite feeds the
fractures in the bedrock and is discharged into creeks south and southwest of the landfill.
Groundwater flow at deeper levels within the fracture bedrock is controlled by fracture
orientation and connectivity. This unconfined aquifer is pervasive across the site and the water
table generally mimics the surface topography.
Historically, depth to groundwater at the site has ranged from approximately 2-5 feet below
ground surface (BGS) on the downgradient (southwest) side of the site, to approximately 28-
33 feet BGS near the northeast corner of the landfill. During the recent sampling period,
groundwater elevation has ranged from approximately 790 feet above mean sea level (MSL)
on the upgradient side of the site to approximately 751 feet MSL on the down gradient side
of the site. Historically, groundwater appears to flow from the northeast to the southwest.
Historical groundwater elevation data for the facility are presented in Table 2. The
groundwater elevations and flow direction based on the July 2021 water level data are
illustrated on Figure 3B Potentiometric Map July 2021.
1.2.1 Groundwater Flow
Aquifer hydraulic properties and groundwater flow velocity calculations are included in Table 3.
The horizontal gradient for the flow path illustrated on Figure 3 was 0.0316 ft/ft. This value
is consistent with previous estimates.
The linear groundwater flow velocities were computed using the modified Darcy equation
of V = Ki/ne, where:
V = average linear velocity (feet/day);
K = hydraulic conductivity (feet/day);
i = horizontal hydraulic gradient; and
ne = effective porosity.

The hydraulic conductivity (K =1.73 feet/day) from slug -tests conducted by JOYCE in April
2013 was used in this calculation. The effective porosity (ne = 30%) was estimated based on
typical values for saprolite in the North Carolina Piedmont. Although the regolith and bedrock
are hydraulically connected, the effective porosity generally decreases with depth into the
underlying fractured bedrock. The calculated linear groundwater velocity (V) is estimated to
be approximately 65 feet/year.
As reported by JOYCE, because of the conservative estimate of effective porosity, actual
groundwater velocities may be significantly less than those calculated. Also, the modified Darcy
equation makes the simplified assumptions of a homogeneous and isotropic aquifer. Actual
velocities may vary significantly in the heterogeneous, anisotropic conditions believed to exist
at this site.
1.2.2 Vertical Gradient
Monitoring wells MW-3S and MW-3D represent a nested pair of wells with different screened
intervals. The estimated vertical gradient based on the water levels measured during the July
2021 sampling event is calculated below. As tabulated below, the calculated upward gradient
is -2.12 feet/foot between these two wells, indicating a moderately weak upward component
to groundwater flow. Since these wells are located near the creek southwest of the landfill,
these data support the contention that the creek is a groundwater discharge feature.

to be one VOC plume and associated AOC continuing at the facility. The AOC is located
hydraulically downgradient of the waste disposal area in the vicinity of MW-2, MW-3S, MW-
3D, and MW-4. The groundwater surface contours illustrated on Figure 313 indicate that
groundwater flow is generally from the northeast to the southeast towards the creek, which is
an unnamed tributary to East Belews Creek. This is consistent with historical data and the
observed plume. The creek, which flows toward the northwest, is believed to be a
groundwater discharge feature and therefore should exert some hydraulic control over the
migration of the VOC plume. During the recent sampling period, there have been few

quantified detections of VOCs in the surface water and no exceedances to the Classifications
and Water Quality Standards Applicable to Surface Waters and Wetlands of North Carolina listed in
15A NCAC 2B (the "2B Standards").
Since 2017, several VOCs have been detected at concentrations that exceed their
respective 2L Standards or the NC Solid Waste Section Groundwater Protection Standards
(GWPS - established for constituents without a currently defined 2L Standard). The constituents
of concern (COCs) for the facility include the VOCs that have been detected in exceedance of
the 2L Standards in one or more downgradient well during the recent sampling period. These
COCs include:
• Benzene,
• 1,1-dichloroethane (1,1-DCA)
• 1,2-dichloroethane (1,2-DCA)
• 1,2-dichloropropane (1,2-DCP), and
• Vinyl chloride.
Monitoring wells impacted by VOCs include MW-2, MW-3S, MW-3D and MW-4, which are
located southwest of the waste unit approximately 130 feet to 450 feet from the western
boundary of the facility.
Table 4 and Table 5 present summaries of NC Appendix I and II organic and inorganic
constituents that have been detected above the 2L Standards or the GWPS. Complete
historical data for detected constituents in groundwater and surface water are presented in
Appendix III. The laboratory analytical reports and field data logs have been submitted in
the corresponding Semiannual Water Quality Monitoring Reports (WQMRs) for the facility.
The laboratory reports and field data logs for the July 2021 sampling event are presented
in the July 2021 Water Quality Monitoring Report (Permit #34-04), which was submitted in
January 2022.
Five VOCs have been detected at concentrations greater than the regulatory Groundwater
Protection Standard (GPS) as defined in NCSWMR §.1634 in the recent sampling period. For
the COCs, the GPSs are the 2L Standards. During the recent sampling event, benzene exceeded
its 2L Standard (1.0 µg/L) in MW-2; 1,1-dichloroethane was detected above its 2L Standard (6.0
(µg/L) in MW-2R; 1,2-dichloroethane was detected above its 2L Standard ( 0.4 µg/L) in MW-
2R, MW-3S and MW-3D; 1,2-dichloropropane was detected above its 2L Standard (0.6 µg/L) in
MW-2R and MW-3D; and vinyl chloride was detected above its 2L Standard (0.03 µg/L) in MW-
2R, MW-3S, MW-3D, and MW-4. Table 4 presents the historical data for these constituents.
Figures 5-13 present isoconcentration maps for the individual COC plumes and for total
VOCs using the July 2021 sample event data. Based on the lack of detections of any
COCs in the surface water samples SW-1, SW-2 and SW-3, immediately downgradient of
the impacted monitoring wells, the plume appears to be limited and contained within the
facility boundary.
As previously discussed, nested wells MW-3S and MW-3D, which are located adjacent to the
creek, exhibit a moderately weak upward hydraulic gradient, indicating that the creek is a
groundwater discharge feature. The deep -screened well MW-3D has higher concentrations

of VOCs than the shallower MW-3S, indicating that the vertical extent of the total VOC
plume is not delineated.
Figures 14-22 present plots of the COCs and total VOCs versus time in all monitoring wells
where they have been detected (MW-2R, MW-3S, MW-3D, and MW-4). The concentrations
of most of the COCs in most wells show downward or stable trends. A review of Figure 22
appears to show a downward trend in total VOCs in all of the wells. The trends indicate that
the geometric distribution of the plume and the concentrations in the plume are generally
stable or decreasing.
In addition to the VOCs, there have been isolated occurrences of inorganic constituents (metals)
detected above the 2L Standard or the GWPs in both upgradient and downgradient
monitoring wells at the site; however, in the last five years the only metals detected at
concentrations above the referenced standards include cadmium and chromium in MW-3S, and
chromium and lead in MW-5. MW-5 is located on the east side of the landfill, in a cross -
gradient location relative to waste and is unlikely to have been impacted by the landfill. The
metals' exceedances do not appear to coincide with the VOC plume; therefore, they do not
appear to be related to a release from the landfill. The metals are believed to represent
naturally occurring variations in groundwater chemistry due to the site geology; therefore, they
are not considered COCs. The historic exceedances of inorganic constituents are summarized
in Table 4.
1.4 Site Conceptual Model
1.4.1 Site Geology
The Town of Kernersville Landfill is located in the Piedmont Physiographic Province (Piedmont)
of North Carolina and is underlain by intrusive granitic rocks of Pennsylvanian to Permian age
which are part of the Charlotte Belt Geologic Unit. A geologic map of the area has been included
as Figure 2 (Espenshade, et al, 1975). The geologic map shows that rock underlying the site is
primarily characterized as quartz monzonite and granodiorite, typically containing large
microcline phenocrysts as well as biotite, muscovite, epidote, and hornblende. It is generally
nonfoliated and may contain thin layers of mafic rock. Just south of the site is an area mapped
as a mafic intrusive body, mainly composed of gneissic metagabbro and metadiorite. The
geologic map does not illustrate any diabase dikes mapped near the site location.
There is relatively limited historical geological data available for the Kernersville landfill. Neither
JOYCE nor WR could locate drilling records or boring logs for wells on the property through
a review of both the Town of Kernersville records and NCDEQ records. In 2012, JOYCE
installed a number of gas probes at the site and boring records were prepared for those probe
installations. In most cases, the borings for the gas probes encountered uniform red clayey
sands that appeared saprolitic. Depths of borings for the probes ranged from approximately
eight feet to approximately 34 ft-BGS. Bedrock was not encountered in any of those borings.
1.4.2 Site Hydrogeology
The uppermost aquifer is unconfined and includes both saprolite and the uppermost fractured
bedrock, which are well connected and act as a single aquifer. Typically in the Piedmont, the
Correction Action Evaluation Report WithersRavenel

%io Our People. Your Success.
saprolite grades into weathered bedrock which grades into fractured competent bedrock,
resulting in an aquifer in which porosity and permeability decrease significantly with depth.
Groundwater can occur in substantial volumes where soils and saprolite are very thick; but
typically, groundwater is found in minimal volumes in bedrock, primarily restricted to fractures.
Groundwater in the saprolite feeds the fractures in the bedrock and is discharged into
creeks south and southwest of the landfill. Although the regolith and bedrock are hydraulically
connected, the effective porosity generally decreases with depth into the underlying fractured
bedrock. Groundwater flow at deeper levels within the fractured bedrock is controlled by
fracture orientation and connectivity. This unconfined aquifer is pervasive across the site.
Historical water level data are presented in Table 3. A groundwater potentiometric surface map
based on water levels obtained during the July 2021 sampling event is presented on Figure .3B
The water table beneath the facility generally mimics the surface topography, ranging in
depth from approximately three to 30 ft-BGS. Groundwater flow is to the southwest, and
discharges to the creek located south and southwest of the landfill. The creek forms a
hydrologic divide, so that groundwater from the site is not expected to migrate beyond
it. The calculated linear groundwater velocity was approximately 65 feet/year (see Section
1.2 for a more detailed discussion). However, our review of the calculations indicated an
estimated linear velocity of approximately 0.3 ft/yr., significantly less than previously calculated.
Migration of groundwater contaminants are expected to follow the general groundwater flow
paths shown on Figure 3B. The unnamed tributary present along the south and southwestern
border of the waste unit, downgradient of the plume, is a groundwater discharge feature and,
therefore, a hydrologic divide that should prevent migration of the plume beyond it. There are
currently no known preferred pathways that could significantly affect plume migration or the
effectiveness of the groundwater/surface water monitoring network to monitoring plume
migration.
1.5 Regulatory Status
The Kernersville Landfill is regulated under §.0500 of the NCSWMR and is monitored in
accordance with the requirements of §.0600 of the NCSWMR. On November 1, 2012, the Town
of Kernersville received notification from NCDEQ that because detected groundwater impacts
at the site could potentially be crossing the property boundary, the Town needed to submit
a Phased Groundwater Assessment Plan and complete the described groundwater assessment.
In January 2013, JOYCE, on behalf of the Town, submitted a Groundwater Assessment Plan,
which was approved by DEQ on February 14, 2013. In May 2013, JOYCE submitted a
Groundwater Assessment Report for the facility. In a letter dated July 16, 2013, DEQ approved
the Groundwater Assessment Report and called for the Town to select a remedy and submit
a Corrective Action Application within 1 year of the date of that letter. In July 2014, on
behalf of the Town, JOYCE submitted the Corrective Action Application selecting Monitored
Natural Attenuation (MNA) plus Phytoremediation as the remedy. The remedy was approved
by DEQ in a letter dated July 23, 2014. As required by NCDEQ, JOYCE submitted a Corrective
Action Plan (CAP) on behalf of the Town of Kernersville Landfill in October 2014. NCDEQ
approved the CAP in a letter dated November 4, 2014.

2.0 CORRECTIVE ACTION SUMMARY
2.1 Physical and Chemical Changes in Aquifer Conditions
The current groundwater quality monitoring network consists of six monitoring wells, including
one upgradient (background) well and five downgradient (compliance) wells. Monitoring well
locations are illustrated on Figure 2. Monitoring well MW-6 currently serves as the background
well for the facility. Former background monitoring well MW-1 was replaced (by monitoring
well MW-6) due to slow recharge in the well, low well volumes, or being dry during sampling
events. Downgradient monitoring wells MW-2R, MW-3S, MW-3D, MW-4, and MW-5R are
monitored for the Appendix I list of constituents as part of the compliance network for the
facility. Well construction parameters are presented in Table 1, Monitoring Well Construction
Details.
As a condition of the aforementioned CAP, monitoring wells MW-2R, MW-3S, MW-3D, MW-4
and MW-6 are analyzed for the Appendix I list of constituents and for the following Monitored
Natural Attenuation (MNA) constituents:
• Nitrate, sulfate, chloride, sulfide, alkalinity, and
• Total organic carbon (TOC);
Sample analyses are then compared to the 2L Standards, IMACs or GWPs, where appropriate.
Data obtained from the July 2021 semiannual sampling event, including groundwater elevation
and flow, groundwater field parameters, MNA parameters, and constituent concentrations
have been evaluated with regard to the physical and chemical conditions in the uppermost
aquifer at the site. Table 6 presents the recent and historical MNA data for the facility. The
laboratory analytical reports for the MNA data have been submitted in the corresponding
semiannual WQMRs for the facility. The laboratory report for the July 2021 MNA data are
presented in the July 2021 Water Quality Monitoring Report (Permit # 34-04), which was
submitted in January 2022.
Temperature, pH, conductivity, ORP, turbidity, dissolved oxygen, dissolved carbon dioxide, and
ferrous iron fluctuate within normal ranges for groundwater in saprolite of the Piedmont
physiographic province. Conductivity, ORP, alkalinity and chloride concentrations are
significantly higher and sulfate concentrations are lower in the vicinity of the plume than in
the upgradient well. These differences are attributed to the presence of the plume and the
natural attenuation process. Although some MNA parameters have fluctuated or had sporadic
results, there appear to be no systematic differences in groundwater chemistry during the
sampling period. Additionally, there appears to be no significant change or variation in
groundwater elevation and flow or constituent concentrations since the CAP was
implemented. These data indicate no significant changes in the physical or chemical
characteristics of the aquifer during the recent sampling period.

2.2 Physical and Chemical Changes in Plume Characteristics
Surface water at the landfill is monitored semi-annually in conjunction with the groundwater
sampling events. Samples are collected from three surface water monitoring points (designated
SW-1, SW-2, and SW-3). Surface water sample locations are also illustrated on Figure 2.
These surface water monitoring points are summarized below, along with their current
monitoring program status.

SW-2
SW-3
Classification

Compliance
Compliance
Surface water samples are collected and analyzed for the Appendix I list of constituents during
both semiannual monitoring events. Analytical results are compared to the 2B Standards.
Table 5 presents the historical data for the COCs detected during the recent sampling period.
Figures 5-13 present isoconcentration maps for the individual COC plumes and for total VOCs
using the July 2021 sample event data. Based on the lack of detections of any COCs in
the surface water samples the plume appears to be limited and contained within the facility
boundary. There is no evidence of the plume either increasing or decreasing in horizontal or
vertical extent since the CAP was prepared in 2014.
Figures 14-22 present plots of the COCs and total VOCs concentrations versus time in
monitoring well MW-2R, MW-3S, MW31D, and MW-4. The concentrations of most of the
COCs in most wells show downward or stable trends. Vinyl chloride concentrations show
slightly decreasing trends in MW-3S, MW-31D, and MW-4, and appear to have stabilized over the
recent sampling period in MW-2R. A review of Figure 22 appears to show a downward trend of
total VOCs in all of the wells. The trends indicate that the geometric distribution of the plume
and the concentrations in the plume are generally stable or decreasing. These data indicate
that there have been no significant changes in the chemical or physical characteristics of the
contaminant plume since 2016.
2.3 Refining the Site Conceptual Model
Any new information that comes to the attention of the facility, either from the data collected
on site or other sources, which impact the site conceptual model will be reported and
evaluated. This includes data on site or regional geology, hydrogeology, or other aspects of the
site conceptual model. The site conceptual model will be refined in response to the new
information as needed and appropriate.
The landfill is bound to the south and southwest by an unnamed tributary of East Belews Creek,
and to the east by a drainage feature that flows south into the unnamed tributary. The unnamed
tributary flows to a confluence with East Belews Creek more than 2000 feet northwest of
the facility property.

Historically, three surface water points [SW-1 (upstream), SW-2 (downstream), and SW-3
(midpoint)] have been sampled semiannually in conjunction with the groundwater sampling at
the facility. Historical surface water sampling data indicate that groundwater discharge into the
creek has not impacted the surface water; therefore, the surface water does not constitute
a sensitive receptor pathway risk. If the plume migrated to impact the surface water, dilution
would likely reduce the concentrations to below detectable levels with a short distance
downstream.
Flora and fauna on or above the ground surface are at minimal risk, because there have been
no confirmed detections of the COCs in the downstream surface water samples. Organisms
suspected to be living in the subsurface at the site are at potential risk; however, soil
microorganisms are known to use the organic acids and by-products of the degradation process
of the groundwater plumes as a food source; therefore, the potential risk to the environment
from the impacted groundwater is considered to be low. JOYCE conducted tree surveys in
June 2015 and April 2016 and no evidence of distressed vegetation or obvious impacts to
wildlife were observed because of exposure to the contaminant plume. During the recent
sampling period, WR personnel also did not note any significant evidence of distressed vegetation
or obvious impacts to wildlife potentially exposed to the contaminant plume. In 2019, in response
to site inspection comments by Section Environmental Senior Specialist, Ms. Susan Heim, the
Town re -graded the landfill surface to promote more efficient surface run-off. At the same time,
the Town also re -graded the southwestern side slope of the landfill removing volunteer trees and
undergrowth which had gown up on the slopes over the last five years.
As noted above, the VOC plume remains relatively unchanged, and there is no data indicating
a need to modify the site conceptual model at this time.
WR plans to conduct a new tree survey in Summer 2022.
2.4 Evaluation of the Impact of Corrective Actions
2.4.1 Contamination Levels
Figures 14-22 present plots of the COCs and total VOCs concentrations versus time in
monitoring well MW-2R, MW-3S, MW3D, and MW-4. The concentrations of most of the
COCs in most wells show downward or stable trends. Vinyl chloride concentrations show
slightly decreasing trends in MW-3S, MW-3D, and MW-4, and appear to have stabilized over the
recent sampling period in MW-2R. A review of Figure 22 appears to show a downward trend of
total VOCs in all of the wells. The trends indicate that the geometric distribution of the plume
and the concentrations in the plume are generally stable or decreasing. These data indicate
that there have been no significant changes in the chemical or physical characteristics of the
contaminant plume since 2016.
2.4.2 Evaluation of MNA Parameters
In accordance with the CAP for the facility, MNA baseline sampling was initiated with the
November 2014 sampling event; therefore, the June 2016 sampling event was the fourth
and final baseline sampling event for MNA.

The MNA performance parameters provide insight into the microbial and biogeochemical
reactions and processes that are occurring within the subsurface. In accordance with the CAP,
the baseline sampling has included the following MNA performance parameters. Some of these
parameters will be analyzed in the field at the time of sampling while others will be collected for
laboratory analysis, as indicated in parentheses below.

As reported above in Section 1.1 Site Background, JOYCE submitted a Corrective Action
Evaluation Report (CAER) in October 2016 in accordance with the Section's Guidelines for
Corrective Action Evaluation Reports. In their Conclusions and Recommendations, JOYCE
recommended that 1,2-dichloroethylene, BOD and COD be removed from the MNA analytical
requirements for this facility. JOYCE also requested reducing the frequency of MNA monitoring
to twice per CAER period, during the two semiannual events immediately prior to the next, and
subsequent, CAERs for the following MNA parameters:
• Methane, ethane, and ethene
• Dissolved CO2
• Volatile Fatty Acids
• Ferrous Iron (Fe2+)
In a response letter (DIN27098) to the Town dated December 6, 2016, the Section approved
the request to remove cis-1,2-dicholorethylene from the COC list. However, the request to
modify the MNA monitoring frequency for the above -listed MNA parameters was not approved
but changed to continually monitoring them semi-annually (both sampling events) every three
years.
Table 6 presents a summary of MNA parameter results during the recent sampling period
(September 2017 through July 2021). Typical definitions of Standard MNA Parameters are
presented below:
Temperature of groundwater is used to help assess the representativeness of water
samples, and to correct temperature sensitive parameters/measuring devices.
Microorganisms are active over a wide temperature range, although some may become
more active with increasing temperature. Temperature measurements for groundwater
samples during the recent sampling period have fluctuated between 8.4 °C and 22.4'C.

• pH is an indication of the suitability of environment to support wide range of microbial
species. Activity tends to be reduced outside of pH range of 5 to 9, and anaerobic
microorganisms are typically more sensitive to pH extremes. pH is also used to help assess
the representativeness of the water sample taken during purging of wells. All pH
measurements of groundwater at the site during the recent sampling period have been
between 3.2 and 7.0.
• Conductivity of groundwater is a measure of its ability to conduct electricity. The standard
unit of conductivity is micro -Siemens per centimeter (µS/cm). Conductivity measurements
are used in environmental applications as a way of measuring the ionic content in water.
Conductivity in downgradient wells have ranged from 0.03 to 397.1 µS/cm. These values
are, on average, significantly higher than the 0.035 µS/cm to 0.05 µS/cm observed in
the background well, MW-6, during the recent sampling events. This is an indication on
increased ionic content in the vicinity of the plume.
• Oxidation -Reduction Potential (ORP) also referred at as redox potential or Eh, measures
whether the environment is reducing or oxidizing. Ranges from 0 to +500 mV indicate
oxidizing (aerobic) environments, and ranges from -500 mV to 0 indicate reducing
(anaerobic) environments. The ORP measurements have fluctuated between -44.1 and
257.0 mV in downgradient wells and have been generally lower than the 47.8 mV
observed in MW-6 in July 2021. The ORP data indicate a weakly aerobic environment in
the plume, but less aerobic than the upgradient environment. Biological activity associated
with natural attenuation is expected to reduce the ORP, so these data indicate ongoing
biodegradation.
• Dissolved Oxygen (DO)_is an indicator of aerobic versus anaerobic environments. The
availability of oxygen is essential for aerobic microbes to metabolize organic contaminants,
but DO > 5 mg/L is detrimental to the ability of anaerobic microbes to metabolize organic
contaminants. Groundwater from downgradient wells showed fluctuations in DO
concentrations over time, ranging from 0.23 to 14.3 mg/L; however, the DO
concentrations were generally lower than the 2.38 mg/I observed in MW-6 in July 2021.
The key observation is that there is sufficient oxygen in the plume area to facilitate
biodegradation of constituents like benzene which require an anaerobic environment, but
not too much oxygen to shut down anaerobic biodegradation required for most chlorinated
VOCs. The decreased DO in the plume indicates ongoing aerobic biodegradation.
• Chloride is an ultimate daughter product of reductive dehalogenation and is usually an
indicator of anaerobic degradation of chlorinated hydrocarbons; however, chloride
production has been documented to occur also in association with biodegradation of
benzene. Chloride concentrations within the plume have consistently been an order
of magnitude greater than in background well MW-6 (1.5 mg/L in July 2021), with
concentrations ranging from 9.65 to 36.5 mg/L during this recent sampling period. This is a
strong indication that natural attenuation is occurring.

• Nitrate and Sulfate compounds can be used as electron acceptors by reducing bacteria.
Changes in concentrations may provide evidence of biological activity. At high
concentrations, they may interfere with reductive pathways. In general, one would expect
concentrations of nitrate and sulfate to decrease if active biodegradation is occurring.
Concentrations of sulfate have been consistently lower in the wells within the plume than
in the upgradient well, ranging from 97.5-10.4 µg/L. Concentrations of nitrate have
generally been slightly lower in the wells within the plume than in the upgradient well,
ranging from below the detection limit to 69.0 µg/L.
Extended MNA Parameters have also been recorded periodically at this site. Typical definitions
of specific Extended MNA Parameters are presented below:
• Dissolved Hydrogen (DH) concentrations in anaerobic environments can be correlated with
types of anaerobic activities. DH may be the limiting factor for complete dechlorination of
chlorinated hydrocarbons. A concentration greater than 1 nM in considered necessary
for effective reductive dehalogenation. Concentrations of DH have little impact on the
aerobic degradation, such is expected for benzene. In general, the measured DH
concentrations have ranged between 5.4-8.7 nM in most wells. The primary conclusion is
that there is sufficient hydrogen to support anaerobic dehalogenation of chlorinated VOCs.
• Sulfide presence may provide evidence of sulfate reduction; however, it may not be detected
even if sulfate -reducing bacteria are active because it can react with various oxygenated
chemical species and metals. Sulfide readings during the recent sampling period ranged from
7.0-148 µg/L.
• Alkalinity level increase may be indicative of carbon dioxide production and mineralization
of organic compounds. Alkalinity has ranged from 123 to 194 mg/I in the wells within the
plume, compared to only 9.96 mg/L in the upgradient well MW-6 in July 2021. This is a
strong sign that natural attenuation is occurring.
• Total Organic Carbon (TOC) in significant concentrations indicates the availability of general
growth substrates for microorganisms. One would expect TOC to also be higher inside
the plume than outside of it. The TOC concentrations inside the plume have ranged from
0.50-5.170 mg/L, with significant fluctuations. The TOC concentrations in MW-6 ranged
from 1.0 to 2.450 mg/L in July 2021. These data imply that there is less organic matter
in the plume area than is considered conducive to sustain biological activity.
• BTEX (the sum of benzene, toluene, ethylbenzene, and xylenes) in significant concentrations
indicate the availability of general growth substrates for microorganisms. There have been
no detections of toluene, ethylbenzene, or xylenes in any well during the recent sampling
period, so the BTEX is simply the benzene concentration, which has ranged from BDL to
4.7 µg/L. This is lower than the concentrations considered conducive to sustain biological
activity. An anomalous concentration of 9.0 µg/L was recorded in MW-1, upgradient of the
landfill cell, in January 2021.

• Biological Oxygen Demand (BOD) is based on the activities of bacteria and aerobic
microorganisms which feed on organic matter in presence of oxygen. The result of a
BOD test indicates the amount of water -dissolved oxygen (mg/L) consumed by
microbes. In general, the higher the BOD, the higher the amount of pollution in the test
sample. Typical values for pristine rivers will have BOD below 1 mg/L. Moderately polluted
rivers may have a BOD value in the range of 2.0 to 8.0 mg/L. The BOD value in the
background well, MW-6, was below the detection limit (<2.0 mg/L) during the recent
sampling period. In MW-2, the BOD values ranged from 7.7 mg/L in September 2017 to
<2.0 mg/L as the recent sampling period progressed to 2021. The BOD values in MW-
3S, MW-3D and MW-4 have consistently been <2.0 mg/L. The higher values indicate
heightened biological activity within the plume, which implies significant biodegradation
of the BOD is occurring; however, these results have not been consistent.
• Chemical Oxygen Demand (COD) tells how much oxygen is needed to fully oxidize
compounds containing carbon, hydrogen or both. As an indicator of the amount of organic
pollutants found in groundwater, COD indicates the mass of oxygen consumed per liter
(mg/Q. The COD was typically less than the laboratory method detection limit (also
referred to as Non -Detect (ND)) in MW-6 and has been ND in most of the samples from
within the plume throughout the recent sampling period; however, there have been a few
higher detections (36.0 mg/L in MW-3S and 38.0 mg/L in MW-3D in July 2018). The higher
values indicate heightened biological activity within the plume, which implies significant
biodegradation of the COD occurs periodically.
As mentioned above, the Section gave relief to analyzing certain MNA constituents in 2016.
Subsequent communications between the Section (Ms. Drummond) and WR (Ms. Laura Elliott)
re-established the relief until January 2022. Therefore, MNA constituents listed below were
analyzed in January 2019, July 2019, and January 2020, but were not analyzed in July 2020 and
both sampling events conducted in 2021.
• Dissolved Methane, Ethane, Ethene in groundwater can provide evidence of
dechlorination of chlorinated hydrocarbons; however, methane may also indicate activity
of methanogenic bacteria. Methane produced by methanogenic bacteria decomposing
organic waste is common and expected in an MSW landfill. Dissolved methane has
been detected in MW-2R with a relatively high concentration of 8.18 mg/L in January
2019, and a high reading in MW-3D (9.34 mg/L) in July 2018 at lower concentrations
(0.1-0.5 mg/I) in MW-3S, MW-3D, and MW-4. Methane was detected in MW-6 in July
2019 (27.2 mg/Q. The higher methane in MW-2R probably indicates impact by landfill
gas. Low but detectable concentrations of ethane and ethene have been detected in the
plume area sporadically, but most have been ND.

time in MW-6 (3.16 mg/L) in July 2019. During the same sampling event, 5.21 mg/L was
detected in MW-2R, 4.88 mg/L was detected in MW-3S and 9.99 mg/L was detected in
MW-4.
2.4.3 MNA Matrix Evaluation
The MNA parameter data were evaluated in general accordance with the United States
Environmental Protection Agency's (EPA's) Technical Protocol Manual (EPA, 1998) to
determine whether the conditions are conducive to, or whether there is evidence for,
anaerobic degradation of the chlorinated hydrocarbons. Specifically, the results were evaluated
according to the weighted system presented in Table 2.3 of the Technical Protocol Manual,
referred to hereafter as the Biodegradation Screening Matrix. According to this manual, a score
of
• <5 Indicates that there is inadequate evidence for anaerobic natural attenuation,
• 6-14 Indicates that there is limited evidence for anaerobic natural attenuation,
• 15-20 Indicates that there is adequate evidence for anaerobic natural attenuation, and
• >20 Indicates that there is strong evidence that anaerobic natural attenuation is
occurring.
The MNA evaluation was performed based on the results from the July 2021 sampling event
for downgradient wells within the contaminant plume, compared where appropriate to the
background well (MW-6). Where target parameters were not analyzed/recorded during the July
2021 sampling event, due to relief given by the Section, the score was based on the last time the
target parameter was analyzed/recorded. The Biodegradation Screening Matrix is presented in
Table 7 of this report. The total points conservatively awarded for the July 2021 sampling event
was 18, which indicates that there is adequate evidence for anaerobic natural attenuation.
2.4.4 Evaluation of Phytoremediation
WR did not conduct phytoremediation assessment during the recent sampling period. An
assessment will be conducted beginning in early 2022 sampling event and extending through
the next five-year sampling period. In their 2016 CAER Report, JOYCE concluded that "the
presence of wetlands downgradient of the plume is expected to enhance phytoremediation at
this site, and no changes or augmentation to the phytoremediation remedy are needed at this
time."
2.4.5 Impacts on Hydraulic Gradients
Based on historic groundwater elevations at this site, the average hydraulic gradient is 0.0316
ft/ft toward the southwest, with an estimated horizontal flow velocity of approximately 65
feet per year. The most recent estimate of hydraulic gradients and groundwater flow
velocities are provided in Table 3 of this report and are discussed in Section 1.2.1. There is
currently no pumping or injection associated with the corrective action at this facility;

therefore, there is no impact on hydraulic gradients.
2.4.6 Contaminant Removal Efficiencies and Mass of Contaminants Removed
The CAP specifies that the EPA's BIOCHLOR Natural Attenuation Decision Support System
(Version 2.2) will be used as a screening model to evaluate MNA at the Town of Kernersville
Landfill facility. BIOCHLOR is an easy -to -use screening model which simulates remediation by
natural attenuation of dissolved solvents at chlorinated solvent release sites (USEPA, 2002).
BIOCHLOR includes three different model types:
• Solute transport without decay;
• Solute transport with biotransformation modeled as a sequential first -order decay
process; and
• Solute transport with biotransformation modeled as a sequential first -order decay
process with two different reaction zones (i.e., each zone has a different set of rate
coefficient values).
The software, programmed in the Microsoft Excel spreadsheet environment and based on
the Domenico analytical solute transport model, has the ability to simulate one-dimensional
advection, three-dimensional dispersion, linear adsorption, and biotransformation via reductive
dechlorination (the dominant biotransformation process at most chlorinated solvent sites).
Reductive dechlorination is assumed to occur under anaerobic conditions and dissolved solvent
degradation is assumed to follow a sequential first -order decay process.
Previously, JOYCE conducted BIOCHLOR modeling for the Town of Kernersville Landfill for the
chlorinated ethenes (PCE, TCE, DCE, & VC) based on the June 2016 concentrations in
MW-2R for a simulated 10 years of biodegradation. The results of the JOYCE modeling efforts
are summarized below.

Analytical results for the groundwater sample obtained from MW-2R for WR in July 2021 did
not identify the detectable presence of PCE, TCE or DCE, which implies that these chlorinated
ethenes have been removed from the groundwater by reductive dichlorination over the past five
years. The vinyl chloride concentration at location MW-2R in June 2021 (4.02 ug/L) is slightly
lower than that detected in June 2016 (4.60 ug/L). Its continued presence in groundwater at
this location appears to be related to the disappearance of the precursor chlorinated ethenes
having been transformed into VC through reductive dichlorination. Due to the absence of PCE,
TCE and DCE within the sample from MW-2R further modeling using BIOCHLOR was not

conducted.
During the July 2021 groundwater sampling event low concentrations of four VOCs in addition
to VC were identified in the groundwater sample from MW-2R. These included benzene (3.07
ug/L), 1,1 dichloroethane (1,1 DCA 9.24 ug/L), 1,2 dichloroethane (1,2 DCA 0.520 ug/L), and
1,2 dichloropropane (1,2 DCP 3.64 ug/L). Measurement of dissolved oxygen in the
groundwater from MW-2R at the time of sampling was approximately 2.85 mg/L, which
indicates the presence of aerobic conditions. Because benzene and vinyl chloride are known
to be amenable to aerobic biodegradation, the EPA BIOSCREEN Natural Attenuation Decision
Support System model was used to predict future concentrations of the four VOCs
downgradient of MW-2R at a time ten years from the present.
Copies of the BIOSCREEN input and output pages for each of the five VOCs detected in the
groundwater sample from MW-2R are provided in Appendix II. Under no degradation
conditions, the model assumes constant contaminant source concentrations, which are the
concentrations of the VOCs detected in MW-2R in July 2021. BIOSCREEN also utilizes the
Domenico analytical solute transport model and simulates one-dimensional advection and
dispersion in runs with an assumed constant source either with or without biodegradation.
Due to the relatively low concentrations of VOCs in the July 2021 sample from MW-2R, and the
slow rate of groundwater flow at the site, the BIOSCREEN runs predict that even under no
degradation conditions, detectable concentrations of the VOCs should not be present in
groundwater 25 to 50 feet downgradient of MW-2R within a ten-year period. Future monitoring
of VOC concentrations in samples from MW-2R and within surface water samples from location
SW-3, which is immediately downgradient of MW-2R can be used to evaluate the validity of the
BIOSCREEN model predictions.
2.5 Migration of the Contaminant Plume
2.5.1 Status of Impacts at the Compliance Boundary
No quantified detections of VOCs have been recorded in the surface water samples collected
from the monitoring point SW-3, which is immediately downgradient of MW-2, nor in the
upstream or downstream surface water samples (SW-1 and SW-2, respectively). Since this creek
is believed to be a groundwater discharge feature, this indicates that the plume in the
uppermost aquifer has not migrated beyond the creek, nor has it migrated beyond the facility
boundary west of the plume. Since there are GPS exceedances in the deep well, MW-3D, the
vertical extent of the plume is not fully delineated; therefore, it is possible that the plume extends
into the fractured bedrock. Groundwater flow in fractured bedrock is less predictable than in
the unconsolidated regolith and saprolite, therefore, we cannot determine whether or not
the plume may have migrated farther at depth in the bedrock fractures.
2.5.2 Off -Site Migration Concerns
The nearest property boundary to the plume is located approximately 135 feet west of MW-
4; however, the direction of groundwater flow and therefore, plume migration is to the
Correction Action Evaluation Report WithersRavenel
Town of Kernersville Landfill, Permit No. 34-04 March 2022

%%
Our People. Your Success.
southwest, and the creek lies between MW-4 and the property boundary in this direction.
However, the highest concentration of VOCs during the recent sampling period were detected
in MW-2r, also located adjacent to the property boundary and creek. The COCs with 2L
Standard exceedances in MW-4 were benzene; 1,1-dichloroethane; 1,2-dichloroethane; 1,2-
dichloropropane, and vinyl chloride. During the recent sampling period, none of these COCs
were detected in the surface water sample collected from SW-3 which is near the property
boundary southwest of MW-2R. Furthermore, there were not any quantified detections of
VOCs in the other surface water sampling points located adjacent to the property boundary.
This supports the contention that the plume has not migrated off site. As discussed above, WR
cannot determine if the plume may have migrated farther at depth in the fractured bedrock;
however, since there are no receptors for the bedrock aquifer, there is no significant risk. Since
there is no evidence that the plume is expanding, there is no reason to expect the plume
to migrate off site in the foreseeable future.
3.0 CONCLUSIONS AND RECOMMENDATIONS
On January 13, 2021, WithersRavenel (WR) personnel mobilized to the facility to purge and
sample monitoring wells MW-1, MW-2R MW-3S, MW-3D, MW-4, MW-5R, and MW-6 and
sample surface water sample locations SW-1, SW-2, and SW-3. Prior to purging each well, the
depth to the static water level was measured with an electronic water level indicator accurate
to 0.01-foot. Due to the lack of water encountered within the well, monitoring well MW-1 was
measured for static water level only. Table 2 presents groundwater surface elevations calculated
from static water levels recorded by WR personnel compared to top -of -well casing elevations
reported by JOYCE in their 2015 reports. For comparison purposes, the most recent sampling event
(January 2021) data are illustrated on some of the figures. Figure 3A illustrates estimated
groundwater flow across the landfill site based on the reported groundwater surface elevations
during the January 2021 sampling event. Figure 3B illustrates estimated groundwater flow
across the landfill site based on the reported groundwater surface elevations during the July
2021 sampling event. As shown on these figures and in recent sampling events, groundwater
appears to be flowing in a southwesterly direction towards an unnamed tributary of East Belews
Creek. Table 3 presents groundwater surface elevations reported by JOYCE between 2009 and
2015, and by WR between 2016 and 2021.
The monitoring wells were purged and sampled using either disposable bailers or submersible
pump. Field parameters, including temperature, pH, specific conductivity, dissolved oxygen,
oxidation-reduction potential, and turbidity, were recorded in the site -specific sampling forms
after purging and before sampling.
Groundwater Sampling Methods
Groundwater samples from each monitoring well were collected directly from a submersible
pump or decanted from disposable bailers into the laboratory -prepared and -provided containers
immediately after purging. Samples were then placed into laboratory -provided coolers, chilled
on ice to approximately 4°C, and delivered to a State of North Carolina -certified laboratory (Pace
Laboratories) under standard Chain -of -Custody (COC) protocol. Field data logs are provided in
Appendix I.

to
Our People. Your Success.
Surface Water Sampling Methods
Surface water samples were collected either directly into laboratory -provided, non -preserved
sample containers, or by decanting the sample from a non -preserved 1-Liter amber glass
container into the appropriate containers. In both methods, samples were collected with the
container opening facing into the current flow. When used, care was taken to not overfill the
preserved sample containers (which could lead to preservative loss) and avoid sample -induced
turbidity. Samples were collected initially from the downstream sample location (previously
designated SW-2 by others), and in sequence upstream, SW-3 and then SW-1 to reduce
potential turbidity in the samples (Figure 2). After sample collection, the samples were placed in
a laboratory -provided cooler, chilled on ice to approximately 4°C, and submitted to Pace
Laboratories under standard COC protocol.
Quality Control
One Field Blank was collected by WR personnel as part of the January 2021 sampling event.
Also, a Trip Blank was prepared by the laboratory to accompany the volatile sampling containers
during shipment to and from the laboratory. The Field Blank was analyzed for the Appendix I
list of constituents only, while the Trip Blank was analyzed for VOCs only.
3.2 Assessment of MNA Indicator Parameters
Based on the efficacy of the indicator parameters discussed, WR recommends they be continued
to be assessed during the semiannual sampling events and reported accordingly in future CAER
reports.
3.3 Modifications Needed to Selected Remedv
Natural attenuation and phytoremediation will not prevent further releases of COCs from
the waste unit; however, natural attenuation and phytoremediation appear to be occurring
beneath the facility at a rate sufficient to keep up with migration of the plume. Evaluation
of indicator parameter data and historical observations of the plume indicate that
biodegradation is occurring beneath the facility at a rate that will prevent migration of
contaminants beyond the property line and will reduce concentrations of constituents -of -
concern within the delineated plume with time.
An evaluation of the risks posed to human health and the environment suggests that there is
low risk due to the fact that groundwater contamination is contained within the facility
property boundary, the adjoining property downgradient of the plume is undeveloped land,
and there are no known human receptors. We conclude that MNA plus phytoremediation
remains an appropriate and effective remedy for the Town of Kernersville Landfill. No changes
to the CAP are recommended.

Our People. Your Success.
3.4 Contingency Plan
The CAP included a contingency plan in the event that MNA plus phytoremediation is shown
to be ineffective at controlling migration of the contaminant plume. The contingency plan
includes implementation of one of two contingency remedies:
1. Control of landfill gas through installation of passive or active gas vents or an
intercept trench; or
2. Installation of a reactive barrier trench to intercept and filter the shallow
groundwater plume.
At this time, MNA plus phytoremediation remains an appropriate and effective remedy for
the Town of Kernersville Landfill. No contingency remedies are recommended.
3.5 Land Use Restrictions
Groundwater beneath the landfill property appears to have been impacted by leachate that
originates from the unlined landfill and/or by the migration of landfill gas as evidenced by the
fact that several VOCs have been detected in downgradient wells in exceedance of their
respective GPS. There is no evidence that the contaminant plume has impacted the surface water
in the creek or that the plume has migrated off site. The current COC plume is stable and
concentrations of most COCs appear to be decreasing. Based on the data presented and
discussed in this CAER, there is no need to impose land use restrictions on the landfill or
adjoining property at this time.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On -Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.

Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be FQC
detected in all environmental media.
Not detected at the Reporting Limit (or MDL where applicable).
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the rA
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal I9
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or SC
duplicated within these ranges.
The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)
Confidence level of 2 sigma.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier
Description
B
The same analyte is found in the associated blank.
C3
The reported concentration is an estimate. The continuing calibration standard associated with this data responded low.
Method sensitivity check is acceptable.
J
The identification of the analyte is acceptable; the reported value is an estimate.

Notes:
1. RL = Reporting limit (NC SWSL).
2. All concentrations are in micrograms per liter (ug/L).
3. NC 2L Standard is the groundwater quality standard established under 15A NCAC 2L.
4. MW = Monitoring well.
5. Blanks = Quality control blanks, including trip, field, and laboratory blanks. The listed concentration is the highest value reported in all blanks associated with the samples.
6. ND = Not detected at the laboratory's detection limit.
7. J = Estimated value since concentration is less than the laboratory's reporting limit and greater than the detection limit.
8. B = Probable field and/or laboratory contamination since the concentration is within five times the concentration reported in the associated quality control blanks.
9. Bold values are greater than the NC 2L Standard or GWPS.
10. DL = Detection limit.
11. GWPS = Groundwater Protection Standard (GWPS is used when the NC 2L Standard has not been established.)
12. --- = Monitoring well was no sampled.

NOTE: Chloroethane, Methane, TCE, DCE, cis-1,2-DCE, MC, VC, DCA, and CO2 are all present in the plume; however,
nM = Nanometer it is uncertain whether these are primary leachate constituents or daughter products (DPs); therefore, we
C = Celcius have two calculation columns. The first column assumes all of these are daughter products, and the
NA = Not Analyzed second column assumes none of them are. The true score is probably between the two.
