1.0 INTRODUCTION
1.1 Site Information
The Town of Kernersville Landfill is a closed, unlined municipal solid waste landfill located on
approximately 58.2 acres in 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) 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.
1.2 Site Geology and Hydrogeology
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 Engineering (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.
1.3 Regulatory Status
The Town of Kernersville (Town) is currently monitoring groundwater at the landfill in
accordance with criteria set forth in Title 15A Subchapter 13B .0500 of the North Carolina Solid
Waste Management Rules for municipal solid waste landfills (MSWLF) closed prior to October
9, 1993. Samples are analyzed for all constituents listed in 40 CFR Part 258, Appendix I
Constituents for Detection Monitoring ("Appendix I") and compared to the North Carolina
Groundwater Quality Standards as listed in 15A NCAC 2L (the "2L Standards"), or, when a 2L
Standard is not established, the Solid Waste Section's Groundwater Protection Standards
(GWPs).
Based on the presence of targeted Appendix I constituents detected at concentrations above
the referenced standards that could potentially be crossing the facility boundary, the North
Carolina Department of Environment and Natural Resources (NCDENR), Solid Waste Section
July 2019 Water Quality Monitoring Report
Town of Kernersville Closed Landfill, Permit 34-04
WR Project Number 06140180.33

(Section) requested that the Town submit a Groundwater Assessment Plan to evaluate site
conditions as they relate to groundwater quality. JOYCE submitted a Groundwater Assessment
Report to the Section on May 13, 2013, and concluded that, based on site hydrogeology, it would
be very unlikely that the site impacts at concentrations above their respective standards would
cross the property boundaries.
In a July 16, 2013 response to information presented in the Groundwater Assessment Report, the
Section determined that, despite the conclusions presented in JOYCE's Groundwater Assessment
Report, the detection of volatile organic compounds (VOCs) at concentrations that exceeded the
referenced standards beyond the compliance boundary of the site constituted a violation of
Section regulations. JOYCE submitted a Corrective Action Plan (CAP) on behalf of the Town in
July 2014, which the Section approved on November 4, 2014. Note that the NCDENR is now
doing business as the North Carolina Department of Environmental Quality (NCDEQ).
2.0 FACILITY MONITORING PROGRAM
2.1 Groundwater Monitoring Program
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-2, MW-3S, MW-3D, MW-4, and MW-5 are
monitored for the Appendix I list of constituents as part of the compliance network for the
facility. Monitoring well MW-1 is currently monitored for water levels only. Well construction
parameters are presented in Table 1, Monitoring Well Construction Details.
As a condition of the aforementioned CAP, monitoring wells MW-2, MW-3S, MW-3D, MW-4
and MW-6 are also monitored for the following Monitored Natural Attenuation (MNA)
constituents;
• Nitrate, sulfate, chloride, sulfide, alkalinity;
• Total organic carbon (TOC);
• Methane, ethane, and ethane
• Biological oxygen demand (BOD) and Chemical oxygen demand (COD).
Groundwater samples collected semiannually are analyzed for the Appendix I list of constituents
and for the above -referenced MNA parameters. Sample analyses are then compared to the 2L
Standards or GWPs, where appropriate.
2.2 Surface Water Monitoring Program
Surface water at the landfill is monitored semiannually 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.

Surface water samples are collected and analyzed for the Appendix I list of constituents during

Water Quality Standards Applicable to Surface Waters of NC as listed in 15A NCAC 2B (213
Standards).
3.0 GROUNDWATER AND SURFACE WATER SAMPLING EVENT
3.1 Field Services
On July 24, 2019, WithersRavenel (WR) personnel returned to the facility to purge and sample
monitoring wells MW-1, MW-2, MW-3S, MW-3D, MW-4, MW-5 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, Groundwater Surface Elevations 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 (July 2019) data are illustrated on some of the
figures. Figure 3A, Potentiometric Map (July 2019) illustrates estimated groundwater flow
across the landfill site based on the reported groundwater surface elevations during the July
2019 sampling event. Figure 313, Potentiometric Map (January 2019) illustrates estimated
groundwater flow across the landfill site based on the reported groundwater surface elevations
during the January 2019 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 Belews Creek. Table 3, Historical Groundwater Elevations presents groundwater
surface elevations reported by JOYCE between 2009 and 2015, and by WR between 2016 and
2019.
The 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 log book prior to purging,
after each purge volume, and during sampling.
Groundwater samples from each monitoring well were collected directly from a submersible
pump into laboratory -cleaned and -provided containers or decanted from disposable bailers into
the 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 Analytical Laboratories) under standard Chain -of -Custody (COC) protocol.
Field data logs are provided in the Appendix to this report.

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 overflow the
preserved sample containers (which could lead to preservative loss) and avoid sample -induced
turbidity. Samples were collected initially from the downstream sample location (SW-2), and in
sequence upstream, SW-3 and then SW-1 samples were collected (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 Analytical Laboratories under standard COC protocol.
3.2 Quality Control
One Field Blank was collected by WR personnel as part of the July 2019 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.
4.0 ANALYTICAL RESULTS
4.1 Groundwater
Groundwater samples were analyzed for the Appendix I list and the modified list of MNA
constituents and compared to the respective 2L Standards or GWPs where appropriate. As
shown on Table 4, Groundwater Analytical Results, the following organic and/or inorganic
constituents were detected in groundwater samples during the July 2019 sampling event. All
concentrations are reported in micrograms per liter (µg/L). Concentrations detected above the
2L Standard or GWPs are illustrated in bold font.

4.2 Surface Water
Surface water samples were analyzed for the Appendix I list only. No analytes were detected at
concentrations above the 2B Standards in surface water samples collected during the July 2019
sampling event. The results were consistent with historical data. Surface water data can be
found in Table 5, Surface Water Analytical Results. The results, as reported by the laboratory,
historical surface water data, the laboratory quality/assurance/quality control information, and
the chain -of -custody records are included in the Appendix.
5.0 MONITORED NATURAL ATTENUATION (MNA) EVALUATION
5.1 MNA Parameters
According to previous reports, in accordance with the facility CAP, MNA baseline sampling was
initiated during the November 2014 sampling event and finished during the November 2015
sampling event. During those events, the full list of MNA parameters (shown below) were
measured in samples collected from monitoring wells MW-2, MW-3S, MW-3D, and MW-4.
MNA field (geochemical) parameters included:
• Temperature;
• pH;
• Specific conductance;
• Oxidation-reduction potential (ORP);
• Turbidity; and
• Dissolved oxygen.
Laboratory parameters included:
• Biological Oxygen Demand (BOD);
• Chemical Oxygen Demand (COD);
• Dissolved hydrogen;
• Nitrate;
• Sulfate:
• Chloride;
• Alkalinity;
• Sulfide;
• Total Organic Carbon (TOC);
• Ethane, ethene, and methane; and
• Volatile fatty acids.
As shown on Table 6, Summary of MNA Constituents, WR sampled for the full list of MNA
parameters during the July 2019 sampling event. Laboratory reports and field data forms are
included in the Appendix.
5.2 Biodegradation Screening Matrix
The MNA parameter data were evaluated in general accordance with the weighted system
presented in Table 2.3, Biodegradation Screening Matrix (Matrix) of the United States
Environmental Protection Agency's (USEPA's) Technical Protocol for Evaluation of Natural
Attenuation of Chlorinated Solvents in Groundwater (Manual), to determine whether the conditions
are conducive to, or whether there is evidence of, anaerobic degradation of the chlorinated
hydrocarbons. According to information presented in the Manual,

. ■ Our People. Your Success.
• A score less than 5 indicates that there is "inadequate evidence" for anaerobic natural
attenuation;
• A score of 6 to 14 indicates that there is "limited evidence" for anaerobic natural attenuation;
• A score of 15 to 19 indicates that there is "adequate evidence" for anaerobic natural
attenuation; and
• A score of 20 or more indicates that there is "strong evidence" that anaerobic natural
attenuation is occurring.
The MNA evaluation was performed based on the results from the July 2019 sampling event for
downgradient wells located within the contaminant plume and compared, where appropriate, to
samples collected from the background well (MW-6). Because it is unclear whether some of the
target analytes are naturally -occurring or daughter products resulting from natural attenuation,
the scores have been calculated with and without the daughter product points.
The site -specific Matrix for this sampling event is presented in the Appendix. As shown, the
scores ranged from 12 to 24 (characterized as "limited evidence of natural attenuation" to
"strong evidence of natural attenuation.") The mid -range (or average score of 18), indicates there
is "adequate evidence of natural attenuation."
6.0 FINDINGS
Target analytes detected above their respective 2L Standards and/or GWPs in groundwater
samples collected during the July 2019 sampling event appear to generally be consistent with
previous events. In addition, there were no target analytes detected in the surface water
samples at concentrations above their respective 213 Standards. The Town of Kernersville
Landfill will continue to monitor groundwater in accordance with the approved CAP. The next
semiannual sampling event is tentatively scheduled for January 2020.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
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
FTChave
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
FSS
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
ONE LAB. NATIONWIDE.
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.
Abbreviations and Definitions
CP
IP
FTC
FSS
MDL
Method Detection Limit.
ND
Not detected at the Reporting Limit (or MDL where applicable).
[Cn]
RDL
Reported Detection Limit.
Rec.
Recovery.
FSr
RPD
Relative Percent Difference.
SDG
Sample Delivery Group.
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
6
QC
(S)
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U
Not detected at the Reporting Limit (or MDL where applicable).
Analyte
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
a
Dilution
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
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.
FSC
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample
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.
H The indicated analytical results were generated from a reinjection of the same sample extract or aliquot.
J The identification of the analyte is acceptable; the reported value is an estimate.
J- The associated batch QC was outside the lower control limits; associated data has a potential negative bias.
K1 The sample dilutions set-up for the BOD/CBOD analysis did not meet the oxygen depletion criteria of at least 2 mg/L.
Reported result is an estimated value.
K6 Glucose/glutamic acid BOD/CBOD was below method acceptance criteria.
P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit.
Q Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations should be
considered minimum values.
T8 Sample(s) received past/too close to holding time expiration.

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,
it is uncertain whether these are primary leachate constituents or daughter products (DPs); therefore, we
have two calculation columns. The first column assumes all of these are daughter products, and the
NA = Not Analyzed I second column assumes none of them are. The true score is probably between the two.
