1.0 INTRODUCTION
1.1 Site Information
The Johns River Waste Management Facility (JRWMF) is located in the north-central portion of
Burke County, north of Morganton, North Carolina. The 318-acre landfill property is bounded
by Lower Creek to the north and east, and the Catawba River to the south. The Catawba River
forms Lake Rhodhiss along the southeastern property line (Figure 1). Lake Rhodhiss is a long,
narrow lake formed by the Rhodhiss Hydroelectric Dam located approximately 12 miles
downstream of the landfill. The John’s River flows into the Catawba River near the southwest
corner of the landfill property.

The site has rolling topography with elevations ranging from 975 feet to 1,150 feet above mean
sea level (MSL). The central portion is generally gently sloping and contains the higher
elevations; relatively steep slopes and significant drainage features are located around the
perimeter. The 100-year flood boundary extends onto the landfill property. The adjacent
property to the west of the Johns River Waste Management Facility consists of undeveloped,
heavily wooded land. Properties within 2,000 feet of the landfill boundary are covered by
surface water or are heavily wooded.

The unlined waste disposal unit consists of 28 acres in the southwest corner of the landfill
property. The municipal solid waste (MSW) landfill began operation in April 1988, but was
closed to comply with Rule .1627(c)(10)(A) of the NCSWMR, a regulation governing MSW
Landfills units that were not designed with a base liner and leachate collection system. Burke
County has operated a permitted Construction and Demolition (C&D) disposal area on top of the
closed portions of the MSW landfill since 1998. A MSW transfer facility is located in the
eastern half of the property. In 2014, Phase 1A of the C&D expansion was constructed
northeast of the C&D over MSW landfill. Results of groundwater monitoring for Phase 1A will
be presented in a separate report. A site plan showing all the pertinent features of the facility is
provided in Drawing 1.

1.2 Site Geology
The John’s River Waste Management Facility is in close proximity to the Brevard Shear Zone,
and is underlain by highly metamorphosed rocks including gneiss, schist, as well as calc-silicate
rocks, felsic rocks, and metavolcanic rocks. The dominant rock type at the facility is biotite-
muscovite schist, as seen in outcrops, boulders, and rock cores located on site. The structures
within limited outcrops indicate that these rocks are complexly-folded, with attitudes that vary
from vertical to horizontal in most outcrops. The site regolith is typical of the inner piedmont
and consists mostly of silty sand, clayey sand, and sandy silt. The regolith is up to 100 feet thick
and varies in thickness with topography.

An abundance of rounded gravel, cobble, and boulder-sized alluvial deposits are exposed along
the banks of the Catawba River, which borders the site. The greatest accumulation of these
deposits is along the southwestern site boundary. These river deposits are 40 feet or more above
the current river elevation and have been described as ancient river terrace deposits.

1.3 Regulatory Status
The following report of groundwater monitoring data from the JRWMF has been prepared in
accordance with the North Carolina Solid Waste Management Rules (NCSWMR) 15A NCAC
13B §.1632 (Groundwater Sampling & Analysis Requirements) §.1633 (Detection Monitoring
Program), and §.1634 (Assessment Monitoring Program). The facility has operated under these
programs under the auspices the North Carolina Department of Environment and Natural
Resources (NCDENR), which is now the Department of Environmental Quality (NCDEQ). To
avoid confusion, NCDEQ will be used in reference to this department throughout this report
even in reference to past events or documents when it was the NCDENR.

The C&D over MSW landfill has been in the Assessment Monitoring Program since August
1995. In January 2000, Burke County submitted a Water Quality Assessment Report (WQAR),
for the landfill to the NCDEQ. The WQAR determined that the constituents-of-concern (COCs)
at the landfill were several volatile organic compounds (VOCs), specifically: benzene; 1,4-
dichlorobenzene; methylene chloride; tetrachloroethylene; and trichloroethylene.

The JRWMF entered the Corrective Action Program following the correspondence received
from the NCDEQ Solid Waste Section (SWS) dated August 18, 2003. An Assessment of
Corrective Measures (ACM) was submitted to NCDEQ in February 2005. A public meeting was
held on May 16, 2006 in order to receive public comments regarding the ACM as required by
NCSWMR §.1635 (d). A Corrective Action Plan (CAP) was submitted to NCDEQ in June 2008
and revised in November 2008. The CAP was approved by NCDEQ in a letter dated January 29,
2009. An addendum to the facility’s CAP was submitted to the NCDEQ in August 2013, adding
control of landfill gas as a remedy for groundwater impacts on the northeastern side of the
landfill between the old landfill and the new C&D expansion area.

2.0 FACILITY MONITORING PROGRAM
2.1 Groundwater Monitoring Program
Groundwater monitoring at the C&D over MSW landfill is performed in accordance with
NCSWMR §.1634, the site’s Transition Plan (JOYCE, April 1994), and the sites Corrective
Action Monitoring Plan (CAMP) (Joyce, 2008) Groundwater samples are collected
semiannually and analyzed for constituents according to the sampling plan submitted to the SWS
on October 29, 1999. Following is a summary of the compliance monitoring wells and other
wells in the immediate vicinity of the landfill.

Notes: Comp. = Compliance Parameters: NCSWMR Appendix I and/or Appendix II organics and inorganics
plus C&D parameters, as required for routine assessment or detection monitoring.
COCs = Constituents of Concern.
MNA = Monitored Natural Attenuation Parameters: Temperature, pH, specific conductance, oxidation
reduction potential, dissolved oxygen, nitrate, sulfate, chloride, dissolved hydrogen, sulfide, alkalinity,
TOC, methane, ethane, ethene, volatile fatty acids, carbon dioxide, ferrous iron, and turbidity.
LFG = Landfill Gas Indicators: Dissolved CH4 and dissolved CO2.
* After the baseline period, the NCDEQ approved alternate frequencies for carbon dioxide, sulfide,
volatile fatty acids, ethane, and ethylene. These parameters will be monitored during both semiannual
events every third year.
** After the baseline period, sampling frequency for sentinel wells was changed to annual.
*** Performance wells (MW-36& MW-38) for the control of landfill gas remedy were added in the
August 2013 CAP Addendum. MW-38 is also a compliance well for Phase 1A.

The current compliance groundwater monitoring network at the facility consists of one
upgradient well (MW-21), and six downgradient wells (MW-10, MW-11, MW-12 MW-13,
MW-16S, and MW-16D). In March 1999, monitoring wells MW-16S and MW-16D were
installed as downgradient monitoring wells and well MW-17 was installed as a replacement for
upgradient background well MW-9. These wells were incorporated into the compliance
monitoring network during the second semiannual groundwater monitoring event of 2005 after
receiving approval from the SWS in a letter dated August 1, 2005. The letter also gave approval
to drop MW-9 from the compliance monitoring network. MW-9 was abandoned in July 2006.
There are several other monitoring wells at the facility (including MW-8, MW-14, MW-15S, and
MW-15D) and several piezometers that have been used in the past to collect groundwater data to
supplement the data from the compliance monitoring wells. Sentinel wells MW-18 and MW-19
were installed on April 7, 2009 in accordance with the facility’s Corrective Action Plan.

Due to organic detections in MW-17, a request was submitted in August 2010 to replace MW-17
with MW-20 as the facility background well. MW-20 (originally named PZ-4) was installed as a
piezometer in 1995 for site characterization. The NCDEQ-SWS requested that we sample both
MW-17 and MW-20 for the next 2 sampling events (November 2010 and June 2011), and then
submit a revised Water Quality Monitoring Plan to incorporate MW-20 into the compliance
network as the new background well. MW-20 served as the background well until August 2014
when the new Permit to Operate for Phase 1A C&D Landfill expansion was issued by the North
Carolina Department of Environment and Natural Resources. MW-20 was replaced by MW-21,
(formerly PZ-1). MW-21 will serve as the new background monitoring well for both Phase 1A
and the old C&D over MSW landfills. The former background well for the old C&D over MSW
landfill, MW-20, which is located side-gradient of and to the northeast of Phase 1A, will
continue to be sampled as a compliance well for Phase 1A.

The wells in assessment monitoring (MW-10, MW-11, MW-12, MW-13, MW-16S, and MW-20)
are analyzed for the NCSWMR Appendix I list of constituents plus additional detected Appendix
II constituents and additional required C&D parameters during the first semiannual event, and
for all constituents listed in NCSWMR Appendix II plus additional required C&D parameters
during the second semiannual monitoring event. Monitoring well MW-16D is analyzed for the

Corrective Action Evaluation Report (CAER) Joyce Engineering
John’s River Waste Management Facility, Permit No. 12-03 April 2016

NCSWMR Appendix I plus additional required C&D parameters list during both events.
Monitoring wells MW-11, MW-12, MW-16S, and MW-21 are also sampled for MNA
parameters during each sampling event.

In accordance with the CAP for the facility, MNA baseline sampling was initiated with the June
2009 sampling event and continued through the November 2010 sampling event. The baseline
data were evaluated in a CAER dated May 2011. After reviewing the CAER, in a letter dated
July 12, 2011, the NCDEQ agreed to a reduced frequency for monitoring carbon dioxide, sulfide,
volatile fatty acids, ethane, and ethylene. These parameters will be sampled during both
semiannual sampling events every third year. The next time these parameters will be monitored
will be during the two semiannual events of 2016.

The Corrective Action Monitoring Plan (CAMP) for the facility requires samples from sentinel
wells MW-18 and MW-19 to be analyzed for the facility’s Constituents of Concern (COC’s).
The COC list included the following constituents in 2015:

 Benzene;
 1,4-Dichlorobenzene;
 Methylene chloride;
 Tetrachloroethylene (PCE);
 Trichloroethylene (TCE);
 1,1-Dichloroethane;
 1,2-Dichloroethane;
 Vinyl chloride.
 Alpha-BHC

After the 2011 CAER, the NCDEQ agreed that sentinel wells MW-18 and MW-19 need only be
sampled annually. MW-18 and MW-19 were last sampled during the May 2015 event. During
future events, MW-18 and MW-19 will be monitored for the above COC list plus required MNA
parameters annually.

An addendum to the facility’s CAP was submitted to the NCDEQ in August 2013, adding
control of landfill gas as a remedy for groundwater impacts on the northeastern side of the
landfill between the old landfill and the new C&D expansion area. In accordance with the CAP
addendum, piezometers PZ-36 and PZ-38 were converted to permanent monitoring wells
MW-36 and MW-38 to act as performance wells for the control of LFG remedy. MW-36 and
MW-38 are to be sampled semiannually for the current COC list, plus dissolved methane and
dissolved carbon dioxide.

2.2 Surface Water Monitoring Program
The current surface water monitoring points are SMP-5, SMP-6, and SMP-7. Surface water
monitoring point SMP-5 (located at the southwestern property line) and SMP-6 (located at the
southeastern property line) are both located downstream from existing sediment basins. Surface
water monitoring point SMP-7 is located downstream from the new Phase 1A expansion.

The results from these events, including associated resampling events, were presented in
Semiannual Water Quality Monitoring Reports (WQMRs). The WQMRs included all field
sampling data logs, laboratory analytical reports, and chains-of-custody for all compliance
monitoring wells, corrective action wells, and surface water samples collected during each event.
The WQMRs also included statistical analyses, evaluation of MNA data, Biochlor modeling
(annually), review of the groundwater elevations and flow regime, trend charts for each COC,
and a discussion of the results. The WQMR for the December 2015 semiannual event is being
submitted concurrently with this CAER. For details of each sampling event, please refer to the
associated WQMR.

The historical analytical data are included in this report as Tables 1 through 4. The groundwater
map (Drawing 1), plume maps (Drawings 2-11), and cross-sections (Drawing 12) presented and
discussed in this report are based on the most recent data (December 2015 and February 2016),
except for MW-18 and MW-19, for which the most recent data are from May 2015.

4.0 HYDROGEOLOGICAL CONDITIONS
Based on outcrop and drilling information, the water table appears to occur within regolith
everywhere across the site. This regolith consists of alluvium, residual soils, saprolite, and
variably fractured and weathered layered metamorphic rock. Inspection of drill cuttings and site
outcrops indicates that water in the regolith is transmitted largely through fractures. In this
regard, regolith behaves similar to unweathered bedrock, except that fractures are more
numerous and better connected in the regolith, and will tend to have more isotropic hydraulic
properties. Along the low-lying areas of the Catawba River and its tributaries, the water table
occurs within surficial alluvial deposits overlying the residual soils and weathered bedrock.

Groundwater discharges into creeks to the east and west of the landfill and to the Catawba River
to the south. A groundwater potentiometric surface map, developed from static water level data
obtained in December 2015, is presented as Drawing 1. The potentiometric surface map depicts
groundwater flow primarily to the south.

Depth to groundwater was measured in the compliance monitoring wells at the site prior to
sampling. The December 2015 and historical groundwater elevations are provided in Table 5.
The groundwater elevations were calculated relative to the surveyed measuring point (top of
casing) for each monitoring well. Horizontal groundwater gradients along representative flow
paths were estimated from the December 2015 groundwater contours shown on Drawing 1 and
calculated gradients and flow velocities are summarized in Table 6. Horizontal gradients across
the site ranged from 0.039 to 0.055 ft/ft, with an average of approximately 0.048 ft/ft. This is
consistent with previous estimates.

Linear groundwater flow velocities for wells screened in saprolite were computed using the
modified Darcy equation: V = Ki/ne, where V = average linear velocity, K = hydraulic
conductivity, i = horizontal hydraulic gradient, and ne = effective porosity. The mean of
hydraulic conductivities from slug-tests conducted in 1995 and 2015 (K = 3.28 ft/day) was used
in these calculations, along with an estimated effective porosity of ne = 0.40 (40%) for saprolite
based on laboratory porosities for soil samples from the site.

The estimated linear groundwater flow velocity under the facility ranged from 140-164 feet/year,
with an average flow velocity of approximately 144 feet/year (Table 6). The modified Darcy
equation makes the simplifying assumptions of a homogeneous and isotropic aquifer, which may
yield inaccurate results when applied to heterogeneous and/or anisotropic conditions such as are
believed to exist at this site.

The groundwater flow direction and rate have shown no significant seasonal variations over
several years of monitoring. The groundwater flow regime on this site is well constrained and
predictable. Migration of groundwater contaminants are expected to follow the general
groundwater flow paths and there are no known preferred pathways or barriers to groundwater
flow that could significantly affect plume migration or the effectiveness of the groundwater
monitoring network to monitoring plume migration. The current groundwater monitoring
network remains sufficient for monitoring the groundwater at this facility.

5.0 CORRECTIVE ACTION SUMMARY
5.1 Description of Corrective Action Remedy
5.1.1 MNA plus Phytoremediation
The ACM for the John’s River Landfill facility (JOYCE, 2005a) examined multiple potential
remedies for the groundwater impacts at the facility. Of the potential remedies, Monitored
Natural Attenuation (MNA) plus phytoremediation was determined be the most cost-effective
remedy that meets the requirements set forth in 15A NCAC 13B.1636. The CAP for the facility
(JOYCE, 2008), as approved by NCDEQ in January 2009, presented MNA plus
phytoremediation as the remedy to be implemented. The CAP also 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 consists of in situ treatment of the groundwater
to enhance biodegradation by the injection of proprietary materials (hydrogen-releasing
compounds or oxygen-releasing compounds) or other technologies subject to NCDEQ approval.

The CAP stipulated that after the four baseline sampling events are completed, the MNA data
should be evaluated to determine the effectiveness of each of the MNA parameters in evaluating
the MNA process on this site. The baseline period was completed with the December 2010
sampling event and reported in the 2011 CAER.

The primary component to the primary selected remedy (MNA plus phytoremediation) is the
monitoring. Monitoring requirements are similar for both MNA and phytoremediation, so the
monitoring program is designed to evaluate both together. The CAP included a Corrective
Action Monitoring Plan (CAMP) which established a program for semiannual monitoring of a
network of compliance, performance, and sentinel wells for COCs and a list of natural
attenuation indicator parameters. The specifications of the performance and Sentinel wells are
included in the table presented in Section 2.1 of this report.

The sentinel wells (MW-18 and MW-19) function to monitor for migration of the COC plumes
toward the Catawba River. Samples collected from sentinel wells were obtained semiannually
during the baseline sampling period for both COCs and MNA parameters; however, after the
baseline period, the frequency was reduced to annual.

5.1.2 Control of Landfill Gas
An addendum to the facility’s CAP was submitted to the NCDEQ in August 2013, adding
control of landfill gas (LFG) as a remedy for groundwater impacts on the northeastern side of the
old landfill between the old landfill and the new C&D expansion area (the “northeast area”).
Typically, LFG is made up of approximately 55% methane, 44% carbon dioxide, and 1% other
VOC’s, including vinyl chloride and benzene. Numerous studies have established that VOC’s
present in LFG can readily partition into groundwater. Transfer of VOC’s from gas to
groundwater can occur both in the monitor well and/or outside the monitor well. LFG is the
most likely source of VOC detections in groundwater located upgradient or cross-gradient from
the landfill.

Corrective Action Evaluation Report (CAER) Joyce Engineering
John’s River Waste Management Facility, Permit No. 12-03 April 2016

The 2005 ACM for this facility concluded that control of decomposition gas (LFG) was an
appropriate and viable remedy for groundwater impacts at the John’s River Facility. It is likely
that VOC exceedances in the northeast area are related to LFG; therefore, control of LFG
migration is an appropriate remedy to address groundwater impacts for this area.

The proposed mechanism for control of LFG was installation of passive gas vents in the MSW
waste along the northeastern side of the MSW portion of the C&D-over-MSW landfill. In
November 2013, JOYCE installed seven passive gas vents at the locations shown on Drawing
13. The following table summarizes the total depths (in feet below grade) for each of the gas
vents:

Gas Vent: GV-1 GV-2 GV-3 GV-4 GV-5 GV-6 GV-7
Total Depth: 25.5’ 35.0’ 43.0’ 43.0’ 45.0’ 47.0’ 36.0’

In September 2015, four additional passive gas vents were installed along the top of the landfill.
The locations of these vents are also shown on Drawing 13, and their total depths are
summarized below:

Gas Vent: GV-8 GV-9 GV-10 GV-11
Total Depth: 34.0’ 24.0’ 24.0’ 24.0’

In accordance with the 2013 CAP addendum, piezometers PZ-36 and PZ-38 were converted to
permanent monitoring wells MW-36 and MW-38 to act as performance wells for the control of
LFG remedy. MW-36 and MW-38 are sampled semiannually for the current COC list, plus
dissolved methane (CH4) and dissolved carbon dioxide (CO2) (although due to an oversight,
MW-38 has not been monitored for CO2 – this will be corrected). There are also several
additional wells and piezometers in the northeast area, which although not required by the CAP,
have been sampled for the COC list plus dissolved CH4 and CO2. These include MW-15S,
PZ-12, PZ-30S, PZ-31, PZ-34, and PZ-35.

In addition to groundwater monitoring, several gas vents, gas probes, temporary probes,
monitoring wells, and piezometers have been regularly monitored for methane gas to document
the extent of landfill gas migration in the northeast area. These data are also relevant to
evaluating the control of landfill gas as a groundwater remedy.

5.2 Physical & Chemical Changes in Aquifer Characteristics
Field parameters such as temperature, pH, conductivity, and turbidity, have fluctuated; however,
they have generally stayed in the normal range for fractured metamorphic rock aquifers in the
North Carolina Piedmont and have not changed significantly over the CAER period. Historical
data for these parameters are presented in Table 7. MW-13, the well with the highest
concentrations of several of the COCs, has consistently shown low pH and low specific
conductance, which are likely a result of ongoing biodegradation in the central part of the plume.

5.3 Physical & Chemical Changes in Plume Characteristics
The contaminant plume described in the facility’s Water Quality Assessment Report (WQAR)
(JOYCE, 2000) listed the following COCs:
 Benzene
 1,4-dichlorobenzene (1,4-DCB)
 Methylene chloride (dichloromethane)
 Tetrachloroethylene (PCE)
 Trichloroethylene (TCE)

Between the 2000 WQAR and the 2011 CAER, the following three other constituents have had
detections above their respective NC2L standards and were added to the COC list:
 1,1-Dichloroethane (1,1-DCA)
 1,2-Dichloroethane (1,2-DCA)
 Vinyl chloride (VC)

These additional NC2L exceedances did not represent increases in concentrations in the
groundwater; rather, they represent changes in reporting requirements, laboratory reporting
limits, or NC2L standards. There have been no significant changes in the chemical
characteristics of the down-gradient portion of the plume.

During the present CAER period (2011-2015), two additional constituents have been detected
above their respective NC2L Standard: alpha-BHC and beta-BHC. Alpha-BHC was added to
the COC list after the December 2012 sampling event, and beta-BHC had a confirmed NC2L
exceedance for the first time in the December 2015 sampling event. These constituents are both
pesticides, which have appeared sporadically in various wells at the site. They both have very
low NC2L standards, so that any quantified detection is an exceedance; however, the highest
concentrations of alpha-BHC and beta-BHC to date have been 0.19 and 0.33 µg/L, respectively.

Drawings 2 through 10 depict isoconcentration maps (plume maps) for each of the constituents
with recent exceedance of the NC2L standards. The isoconcentration maps are based primarily
on the analytical results from the December 2015 sampling event; however, since MW-18 and
MW-19 were not be sampled during that event, the data from the May 2015 event are used.
Drawing 11 shows the Total VOC isoconcentration map, which depicts the sum of the
concentrations of all detected volatile organic compounds (VOCs) on the site (both COCs and
non-COCs). Drawing 12 shows two vertical cross-sections through the contaminant plume, and
includes Total VOC contours.

In general, the COC plumes appear to be stable or decreasing in both vertical and horizontal
extent. The benzene plume seems to be slowly increasing in the vicinity of MW-10; however, it
is decreasing in concentration everywhere else. Benzene concentrations in MW-10 exceeded the
NC2L standard for the first time in June 2013. No other constituent plumes appear to be
expanding in this direction. Since the John’s River constitutes a hydraulic barrier along the
eastern property boundary, and since there have been no detections in the nearby surface water

Corrective Action Evaluation Report (CAER) Joyce Engineering
John’s River Waste Management Facility, Permit No. 12-03 April 2016
11
sampling point SMP-5, there is no reason to believe the benzene plume is migrating off site in
this area.

Since there have been no NC2L exceedances in MW-18, MW-19, the downgradient extent of the
plume appears to be stable and remains constrained to the facility property. Since no COCs have
been detected in the deep well, MW-16D, the vertical extent of the plume is also well
constrained and shows no significant changes.

5.4 Refining the Site Conceptual Model
There is no data indicating any need to modify the site conceptual model governing groundwater
flow and migration of the contaminant plume at this time; however, one addition to the site
conceptual model relates to the role of landfill gas migration. Typically, LFG is made up of
approximately 55% methane, 44% carbon dioxide, and 1% other VOC’s, including vinyl
chloride, benzene, and other COCs (Allen, et al, 1997; Deipser and Stegmann, 1994; Cowie,
2004). Numerous studies have established that VOC’s present in LFG can readily partition into
groundwater. Transfer of VOC’s from gas to groundwater can occur both in the monitor well
and/or outside the monitor well as water percolates through the vadose zone. LFG is the most
likely source of VOC detections in groundwater located upgradient or cross-gradient from the
landfill. It is likely VOC exceedances north and northeast of the C&D-over-MSW landfill are
related to LFG; therefore, control of LFG migration is an appropriate remedy to address
groundwater impacts for this area.

5.5 Impacts of Corrective Action - MNA and Phytoremediation
Monitoring requirements are similar for both MNA and phytoremediation, so the monitoring
program is designed to evaluate both together. The emphasis in this section will be on
evaluation of MNA; however, the impacts of MNA and phytoremediation are linked.

5.5.1 MNA Parameters and Biodegradation Screening Matrix
In accordance with the CAP for the facility, MNA baseline sampling was initiated with the June
2009 sampling event and continued through the November 2010 sampling event. The baseline
data were evaluated in a CAER dated May 2011. The December 2015 sampling event was the
tenth post-baseline event. MNA parameter data were obtained for the following wells: the site
background well (MW-21); and downgradient compliance/performance wells MW-11, MW-12,
and MW-16S. MNA field parameters included temperature, pH, specific conductance,
oxidation-reduction potential (ORP), turbidity, dissolved oxygen, dissolved carbon dioxide and
ferrous iron. MNA laboratory parameters included dissolved hydrogen, alkalinity, TOC,
dissolved methane, nitrate, sulfate, and chloride. Table 7 summarizes the MNA data for the
December 2015 event, and historical MNA data are presented in Appendix H. Field data logs
and laboratory reports are included in Appendices A and B, respectively.

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

Corrective Action Evaluation Report (CAER) Joyce Engineering
John’s River Waste Management Facility, Permit No. 12-03 April 2016
12
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 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 20
indicates that there is adequate evidence for anaerobic natural attenuation, and a score greater
than 20 indicates that there is strong evidence that anaerobic natural attenuation is occurring.

The MNA evaluation was performed based on the results from the December 2015 sampling
event for downgradient wells within the contaminant plume, compared where appropriate to the
background well (MW-21). The Biodegradation Screening Matrix is presented in Table 8 of this
report.

One difficulty in evaluation of the Screening Matrix is that the matrix assumes some compounds
(such as, but not limited to methane and vinyl chloride) are daughter products of biodegradation
within the plume; however, at a landfill we cannot eliminate the possibility that they may be
contaminants released directly from the landfill. If we include the scores for these potential
daughter products, our total score could be artificially high; on the other hand, if we exclude
them, the score might be artificially low. Table 8 presents scoring results both with and without
the questionable daughter product scores.

The fact that we are past the baseline sampling period and the sampling frequencies for some
parameters have been reduced creates another difficulty. How should we score parameters that
were not monitored during the December 2015 sampling event? We have historical data for
these parameters indicating that some would likely contribute points and some would not. To
ignore the historical data and treat all unmonitored parameters as if they were negative results
would give an artificially low score; however, using data from previous events may not give an
accurate result. Table 8 presents scoring results both with and without points based on historical
rather than current data.

The following table summarizes the scoring results from Table 8 for all four options for
interpreting the data. The scores ranged from 14 (limited evidence of natural attenuation) to 30
(strong evidence of natural attenuation). In reality, the best score is probably in the middle of
this range, indicating good evidence of natural attenuation.

DP = Points for possible daughter products.
HD = Points based on historical data.

5.5.2 Biochlor Modeling and Mass-Balance Assessment
Anaerobic degradation of organic constituents, specifically chlorinated ethenes and ethanes, was
modeled using the EPA Biochlor System. The Biochlor model was set up to model flow,
dispersion, advection, adsorption, and biotransformation along a generalized flow line running
from the waste unit south toward the river. The concentration in the source area was set equal to
the December 2015 sampling results from MW-13. Wells MW-11, MW-12, and MW-16S were
included in the modeling based on their respective distances from the southern edge of waste as
summarized below:

WELL: MW-13 MW-11 MW-12 MW-16S MW-18 MW-19
MODELED DISTANCE
FROM THE SOURCE (feet): 0 20 60 135 210 430

Modeling was done for both ethenes (a.k.a. - ethylenes) and ethanes. The ethene degradation
sequence goes from tetrachloroethylene (PCE) to trichloroethylene (TCE), to dichloroethylenes
(DCE), to vinyl chloride (VC). The ethane degradation sequence goes from trichloroethane
(TCA) to dichloroethanes (DCA) to chloroethane (CA). Note that DCE is the sum of detected
cis-1,2-dichloroethylene, trans-1,2-dichlorotheylene, and 1,1-dichloroethylene. Similarly, DCA
is the sum of 1,1-dichloroethane and 1,2-dichloroethane.

The plume was assumed to be 1600 feet wide and 500 feet long, based on the width of the plume
at the southern edge of waste and the average distance from the southern edge of waste to the
river. Simulation time was 17 years, based on the time between closure of the MSW landfill and
the October 2014 sampling event. A seepage velocity of 144.0 feet/year was used based on
groundwater flow rate calculations for the December 2015 event as presented in Table 6 of this
report. The input and output of the Biochlor modeling are presented in Appendix A.

The results of the Biochlor modeling indicate reasonable agreement between the modeled plume
degradation and the analytical results for both ethenes and ethanes. In general, the observed
down-gradient concentrations were less than or equal modeled concentrations except for VC and
CA, which are the final daughter products. The fact that VC and CA are higher downgradient is
evidence that reductive dehalogenation is occurring. This supports the contention that
biodegradation is proceeding at an acceptable rate. The mass rate calculations from the Biochlor
modeling are summarized below. Cells labeled “indeterminate” in the following tables indicate
that the data were insufficient for the software to calculate the values. The results indicate a
large percentage of the contaminants are being removed by Biotransformation.

% Biotransformed 80.8% 73.0% 60.9% indeterminate

5.5.3 Trend Charts and Plume Stability
Charts 1-10 show the concentration of key constituents versus time for the wells MW-10,
MW-11, MW-12, MW-13, and MW-16S from the earliest recorded detections through December
2015. In general, most constituents in most wells show decreasing or stable trends, especially
over the last 3-5 years. The clearest long-term increasing trend is for benzene and MW-13;
however, the benzene trend appears to have stabilized in the last few years. 1,4-dichlorobenzene
also shows a clear upward trend in MW-13. MW-13 is located farther north (upgradient) than
the other downgradient wells and is representative of the central part of the plume whereas
MW-11, MW-12, and MW-16S are located nearer the southern leading edge of the plume, and
MW-10 is located near the western edge of the plume. The fact that the concentrations in the
central part of the plume appear to be stable or increasing while the concentrations near the
leading edge seem to be stable or decreasing supports the contention that natural attenuation is
adequately controlling the plume.

Alpha-BHC has had sporadic detections in MW-13 over the last several sampling events, and
beta-BHC had a confirmed detection in MW-11 for the first time during the December 2016
event. There is not enough consistent data for these constituents to establish any trends.

5.5.4 Plume Maps and Cross-Sections
Drawings 2-9 depict the extent of the plumes for the eight VOCs with NC2L exceedances during
the December 2015 sampling event. These include: benzene; 1,4-dichlorobenzene (1,4-DCB);
1,1-dichloroethane (1,1-DCA); 1,2-dichloroethane (1,2-DCA); tetrachloroethylene (PCE);
trichloroethylene (TCE); vinyl chloride; and methylene chloride. These eight VOCs represent
the primary COCs. Alpha-BHC and beta-BHC have only been detected sporadically, and
generally not in more than one well at a time. The beta-BHC plume is shown in Drawing 10, but
there is no plume map for alpha-BHC because it was not detected in any wells during the
December 2015 event. Drawing 11 depicts the total VOC plume, which is the sum of all
detected VOCs, including estimated detections below the SWSL and VOCs that are not COCs.
Drawing 12 shows two vertical cross-sections (profiles) through the C&D-over-MSW landfill
area showing the vertical extent of the total VOC plume.

In general, the COC plumes appear to be stable or decreasing in both vertical and horizontal
extent. The benzene plume seems to be slowly increasing in the vicinity of MW-10; however, it
is decreasing in concentration everywhere else. Benzene concentrations in MW 10 exceeded the
NC2L standard for the first time in June 2013. No other constituent plumes appear to be
expanding in this direction. Since the John’s River constitutes a hydraulic barrier along the
eastern property boundary, and since there have been no detections in the nearby surface water
sampling point SMP-5, there is no reason to believe the benzene plume is migrating off site in
this area.

The PCE, TCE, and methylene chloride plumes have decreased to below the GPS in all wells
except MW-13, which is in the central part of the plume. PCE and TCE degrade to vinyl
chloride under reductive dehalogenation. The fact that PCE and TCE are decreasing at the

Corrective Action Evaluation Report (CAER) Joyce Engineering
John’s River Waste Management Facility, Permit No. 12-03 April 2016
15
downgradient edge of the plume, coupled with the fact that vinyl chloride is found only near the
downgradient edge of the plume, is strong evidence that natural attenuation is occurring and
effectively controlling the migration of VOCs.

5.6 Phytoremediation
The subject property between the contaminant plume and the Catawba River is heavily wooded
and largely wetland. The existing flora are ideal for phytoremediation of groundwater
contaminated by VOCs; therefore, no additional planting or maintenance of the flora has been
needed. The trees and other flora remain healthy and thriving. There is no way to quantify the
impact of phytoremediation in this setting except through monitoring the contaminant plume.
The above discussion of monitoring for MNA largely covers monitoring for phytoremediation as
well, especially the trend analyses and plume stability discussions.

5.7 Off-site Migration of COCs
The benzene plume seems to be slowly increasing in the vicinity of MW-10; however, it is
decreasing in concentration everywhere else. Benzene concentrations in MW 10 exceeded the
NC2L standard for the first time in June 2013. No other constituent plumes appear to be
expanding in this direction. Since the John’s River constitutes a hydraulic barrier along the
eastern property boundary, and since there have been no detections in the nearby surface water
sampling point SMP-5, there is no reason to believe the benzene plume is migrating off site in
this area.

There have been no quantified detections of COCs or exceedances of NC2L standards at sentinel
wells MW-18 and MW-19 during this CAER period; however, there have been some estimated
detections of 1,1-DCA and 1,2-DCA below the Solid Waste Section Reporting Limit (SWSL).
The concentrations of most COCs in the downgradient wells appear to be either stable of
decreasing. Even if impacted groundwater impinges on the Catawba River, dilution will
immediately reduce constituents to undetectable levels. There are no other areas where the
plume is close to a property boundary.

5.8 Methane Migration and Control of Landfill Gas
There are three primary sources of data relevant to evaluating the effectiveness of control of
landfill gas as a groundwater remedy for the northeast area. These include: 1) changes in
concentrations of COCs and/or the extent of the COC plumes in the groundwater; 2)
concentrations of dissolved gases (methane and carbon dioxide) in the groundwater; and 3)
concentrations and extent of migrating methane gas in the vadose zone.

MW-36 and MW-38 act as performance wells for the control of LFG remedy. MW-36 and
MW-38 are sampled semiannually for the current COC list, plus dissolved methane (CH4) and
dissolved carbon dioxide (CO2) (although due to an oversight, MW-38 has not been monitored
for CO2 – this will be corrected). There are also several additional wells and piezometers in the
northeast area, which although not required by the CAP, have been sampled for the COC list plus
dissolved CH4 and CO2. These include MW-15S, PZ-12, PZ-30S, PZ-31, PZ-34, and PZ-35.

Corrective Action Evaluation Report (CAER) Joyce Engineering
John’s River Waste Management Facility, Permit No. 12-03 April 2016
16
Table 9 presents the analytical results for all the wells in the northeast area, including dissolved
CH4 and CO2. These data are also included in all of the COC plume maps (Drawings 2-11) and
cross-sections (Drawing 12), and were used to constrain the northeast portions of the plumes.

In addition to groundwater monitoring, several gas vents, gas probes, temporary probes,
monitoring wells, and piezometers have been regularly monitored for methane gas to document
the extent of landfill gas migration in the northeast area. Table 10 summarizes the methane gas
monitoring data for the northeast area from February 2012 through February 2016. Chart 11
shows methane gas concentrations vs. time. Drawing 13 depicts the methane gas plume in the
northeast area based on the most recent (February 2016) data.

The COC plume maps for most constituents show the northeastern extent of the groundwater
plumes roughly coincide with the extent of gas migration. A few of the COC plumes (1,2-DCA,
PCE, methylene chloride, and vinyl chloride) do not extend as far northeast as the methane gas
plume, and beta-BHC has only been detected in MW-11. The correlation of the edge of the
VOC plume with the edge of the methane gas migration zone strongly supports the contention
that the exceedances in the northeast area are due to partitioning of VOCs from landfill gas.
There has been no significant change (either increase or decrease) in either the extent of the COC
plumes in this area, or the extent of the methane gas plume since the installation of gas vents in
November 2013.

Chart 11 shows the concentrations of methane gas in the northeast area versus time. Methane
concentrations have fluctuated significantly in some probes, wells, etc.; however, there are no
indications of trends or significant changes in concentrations since the installation of gas vents in
November 2013. Similarly, concentrations of dissolved CH4 and CO2 in the groundwater (Table
9) have fluctuated, but there is not sufficient data to determine if there are any long-term trends.

Although we had hoped to see significant reductions in the methane gas plume as a result of the
installation of the passive gas vents, and at least some evidence of decreasing impact of LFG on
the groundwater in the northeast area, it may still be too soon to tell how effective the remedy
will be in the long-term.

6.0 CONCLUSIONS
During this CAER period (2011-2015), several organic constituents continue to exceed their
respective NC2L Groundwater Standards at the John’s River Landfill; however, these
exceedances are generally consistent with previous sampling events and are being addressed by
the CAP for the facility. During this CAER period, two additional constituents have been
detected above their respective NC2L Standard: alpha-BHC and beta-BHC. Alpha-BHC was
added to the COC list after the December 2012 sampling event, and beta-BHC had a confirmed
NC2L exceedance for the first time in the December 2015 sampling event.

Based on evaluation of MNA data, Biochlor modeling, trends of key constituents, and the lateral
and vertical extend of the plumes for all exceeding constituents, JOYCE concludes that the
selected remedy of natural attenuation plus phytoremediation is adequately controlling the

17
contaminant plume downgradient of the old C&D-over-MSW landfill. The contaminant plumes
appear to remain fully contained within the facility boundary.

A new remedy, control of landfill gas, was approved in August 2013 for the area northeast
(upgradient to side-gradient) of the C&D-over-MSW landfill. In November 2013, seven gas
vents were installed on the northeast slope of the landfill. Review of COC plumes, dissolved
methane and carbon dioxide, and methane gas migration data from this area support the
contention that the COC exceedances in the northeast area are due to partitioning of VOCs from
migrating landfill gas. Since the gas vents were installed in late 2013, there has been no obvious
reduction of the methane gas plume or of the concentrations of VOCs in the northeast area;
however, there has also been no increase in either the gas or groundwater plumes. It may be too
early to evaluate the long-term effectiveness of this remedy. The primary purpose of the remedy
in the northeast area is to keep gas impacts from extending to the expansion landfill area, and the
remedy appears to be adequately fulfilling that purpose.

JOYCE recommends that beta-BHC be added to the COC list for this facility. The COC list will
now include:
 Benzene
 1,4-dichlorobenzene (1,4-DCB)
 Methylene chloride (dichloromethane)
 Tetrachloroethylene (PCE)
 Trichloroethylene (TCE)
 1,1-Dichloroethane (1,1-DCA)
 1,2-Dichloroethane (1,2-DCA)
 Vinyl chloride (VC)
 alpha-BHC
 beta-BHC

Overall, the current Corrective Action Program is effective in controlling groundwater
contaminant migration and is protective of human health and the environment. JOYCE does not
recommend any additional remedies or any changes in the Corrective Action Program for the
facility at this time. The next CAER will be due 120 days after the second semiannual sampling
event of 2020.

Notes:
(Abbreviations and Referrences)
All concentrations in micrograms per liter (µg/L) = parts per billion.
--- = Not sampled for this parameter or not reported.
AB = Monitoring well abandoned.
B = Blank-Qualified (Concentration suspected to reflect laboratory or field contamination based on similar concentrations detected in field, trip, or method blanks).
D = Sample was diluted when analyzed.
DL = Laboratory Detection Limit.
GWPS = Groundwater Protection Standard set by NC-DENR-SWS for constituents with no listed NC 2L standard.
When the NC 2L Groundwater Standard has not been established, the GWPS will be used.
J = Estimated value - concentration is less than the RL but greater than the DL.
NC 2L = Groundwater Standard from 15A NCAC 2L.
ND = Not Detected at or above the RL (prior to Dec. 2006) or the DL (after Dec. 2006).
NE = No NC 2L or GWPS established.
NI = Not Installed; monitoring was not yet installed.
RL = Reporting Limit (Lab. Reporting Limit for September 1994 - May 1999; NC PQL for October 1999 - December 2006; and SWSL for December 2006 - present).
Values above the NC2L Standard or GWPS are bold.
Notes: (Event Narratives)
Volatile organics (8260) for MW-9 for November 10, 2004 sampling event were unable to be analyzed and were resampled on December 1, 2004.
There was a resamplinging event on August 2, 2007 for MW-16D because the prevoius samples from the May 2007 were analyzed out of hold time. There were no detects in the resample.
* MW-21 replaced MW-20 as the background well starting with the Fall 2014 sampling event; however MW-20 continues to be sampled as a compliance well for the C&D Expansion (Phase 1A).
See the Water Quality Monitrong Report for the C&D Expansion Area for current results for MW-20.
The dates on the table above reflect the last samples were collected during the semiannual monitoring event. Individual collection dates are preserved in the Lab Reports (Appendix B).
Pace Analytical Re-ran the analysis for Antimony, Chromium, and Vanadium in MW-12 on January 19, 2016 from the samples collected in December 2016, and the results are included in the table.
A Verification Sampling Event was performed for beta-BHC in MW-11 and Antimony and Chromium in MW-12 on February 4, 2016, for the December 2015 event and results are included.

Notes: (Abbreviations and Referrences)
All concentrations in micrograms per liter (µg/L) = parts per billion.
# = Constituent is included on the NC Appendix II list but not on the NC Appendix I list.--- = Not sampled for this parameter or Not reportedAB = Monitoring well abandoned.
B = Blank-Qualified (Concentration suspected to reflect laboratory or field contamination based on similar concentrations detected in field, trip, or method blanks).
D = Sample was diluted when analyzed.
DL = Laboratory Detection Limit.
GWPS = Groundwater Protection Standard set by NC-DENR-SWS for constituents with no listed NC 2L standard.
When the NC 2L Groundwater Standard has not been established, the GWPS will be used.
J = Estimated value - concentration is less than the RL but greater than the DL.
NC 2L = Groundwater Standard from 15A NCAC 2L.0202.ND = Not Detected at or above the RL (prior to Dec. 2006) or the DL (after Dec. 2006).NE = No NC 2L or GWPS established.
NI = Not Installed. Monitoring well not yet installed.
RL = Reporting Limit (Lab. Reporting Limit for September 1994 - May 1999; NC PQL for October 1999 - December 2006; and SWSL for December 2006 - present).
Values above the NC2L Standard or GWPS are bold.
Notes: (Event Narratives)
Volatile organics (8260) for MW-9 for November 10, 2004 sampling event were unable to be analyzed and were resampled on December 1, 2004. There was a resamplinging event on August 2, 2007 for MW-16D because the prevoius samples from the May 2007 were analyzed out of hold time. There were no detects in the resample.* MW-21 replaced MW-20 as the background well starting with the Fall 2014 sampling event; however MW-20 continues to be sampled as a compliance well for the C&D Expansion (Phase 1A).
See the Water Quality Monitrong Report for the C&D Expansion Area for current results for MW-20.
Sample Collection Date Column displays the last day of the Respective Semiannaul Monitoring Event that samples were collected. Each individual sampling point date is preserved in the Lab Reports (Appendix A).

NC 2B = NE (05/15/13)9-Dec-15 0.2 5.0 ND ND ND ND
Notes:
All concentrations in micrograms per liter (µg/L) = parts per billion.
RL = Reporting Limit (Lab. Reporting Limit for September 1994 - May 1999; NC PQL for October 1999 - December 2006;
and SWSL for December 2006 - present).
DL = Laboratory Detection Limit.
NI = Monitoring well not yet installed.
AB = Monitoring well abandoned.
--- = Not sampled for this parameter or Not reported
ND = Not Detected at or above the RL (prior to Dec. 2006) or the DL (after Dec. 2006).
J = Estimated value - concentration is less than the RL but greater than the DL.
B = Blank-Qualified (Concentration suspected to reflect laboratory or field contamination based on
similar concentrations detected in field, trip, or method blanks).
D = Sample was diluted when analyzed.
NC 2B = Groundwater Standard from 15A NCAC 2B.
NE = No NC 2B established.
Values above the NC 2B Standard are bold.
Surface waters classified as WS-IV (water supply IV, highly developed), B (primary recreation, fresh water), and CA (critical area).

* MW-21 replaced MW-20 as the background well starting with the Fall 2014 sampling event; however MW-20 continues to be sampled as a compliance well
for the C&D Expansion (Phase 1A).
May 20, 2015: Shaded dissolved oxygen results are suspect. The DO Sensor began reading very low, re-calibration attempts did not appear to correct the issue.
A short in the DO probe was diagnosed after the field event.-- MW-12 TOC sample for 12/08/15 was broken in transit to the laboratory and could not be analyzed.
