RE: Alternate Source Demonstration Addendum: Volatile Organic Compounds
Rockingham County Solid Waste Management Facility, Permit No. 79-04
Rockingham County, North Carolina
JOYCE Project No. 00401.1701.12, Task No. 01

Dear Ervin:

On behalf of Rockingham County, Joyce Engineering (JOYCE) is submitting the enclosed
Alternate Source Demonstration (ASD) Addendum to address anomalous detections of volatile organic
compounds (VOCs) in sampling points, MW-19, MW-19R and SMP-5, in electronic format. This ASD
has been prepared in response to comments provided by the Department of Environmental Quality
(NCDEQ), and is being submitted pursuant to the Solid Waste Management Rules [15A North Carolina
Administrative Code
(NCAC) 13B.1633(c)(3)].

As discussed in the enclosed ASD, it is our opinion that a preponderance of evidence suggests that the
source of the anomalous VOC detections reported in MW-19, MW-19R and SMP-5, are not leachate that
has been released from the facility’s waste disposal unit. Rather, the source is related the partitioning of
gaseous phase VOCs present in the facility’s landfill gas, into the dissolved phase, resulting in
concentrations of VOCs at levels that are greater than the NC 2L groundwater standards for some
constituents.

Based on these results, Rockingham County is requesting that NCDEQ allow the Permit No. 79-04
Subtitle D Landfill remain in detection monitoring pursuant to 15A NCAC 13B.1633, since it is apparent
that the anomalous VOC detections in the affected sampling points are not related to a release of leachate
from the landfill. Please feel free to contact me at [phone] if you have any questions regarding this
submittal.

Sincerely,
JOYCE ENGINEERING

1.0 INTRODUCTION
1.1 Site Information

The Rockingham County Solid Waste Management Facility (the Facility) is owned and operated
by Rockingham County and is operating under North Carolina Solid Waste Permit Nos. 79-01 and 79-04. The Facility is located off Shuff Road, west of the town of Wentworth, in central Rockingham County, North Carolina. The property boundary is indicated on an excerpt from the
7.5 minute USGS topographic map for Bethany and Southwest Eden, North Carolina (Figure 1).
The property is surrounded by rural wooded areas and farmland.

The Rockingham County Solid Waste Management Facility consists of six waste disposal areas. Areas I, II, III, IV (I-IV) and Area V are closed unlined municipal solid waste (MSW) landfill areas under Permit No. 79-01. The active Subtitle D MSW landfill is covered under Permit No.
79-04. This Alternate Source Demonstration Addendum will focus only on the Permit No. 79-04
Subtitle D MSW Landfill.

1.2 Purpose of this Alternate Source Demonstration Addendum Laboratory analytical results generated during the routine groundwater monitoring program at the
Rockingham County Permit No. 79-04 Subtitle D MSW Landfill (Landfill) indicate that the groundwater beneath the closed landfill has been impacted by low concentrations of volatile organic compounds (VOCs). Three of the Landfill’s monitoring locations (MW-19, MW-19R,
and SMP-5) have constituents present in concentrations that exceed the North Carolina 15A
North Carolina Administrative Code 2L standards ( NC 2L) for groundwater. As a result of these
confirmed detections, Rockingham County has undertaken this Alternative Source
Demonstration (ASD) Addendum in accordance with 15A NCAC 13B.1633(c)(3), to demonstrate that the VOCs detected in the groundwater downgradient from the facility are derived from a source other than landfill leachate.

2.0 SITE GEOLOGY AND HYDROGEOLOGY

2.1 Site Geology

The Facility is located in the Piedmont physiographic province. Geologically, the site is located
in the Milton Belt, which contains schist and gneiss of amphibolite facies, with minor areas of
granitic intrusive rock. The Geologic Map of Region G, North Carolina (Carpenter, 1982), shows bedrock in the vicinity of the site as the mgs unit, which contains biotite gneiss and schist, locally interlayered with hornblende gneiss and schist and felsic gneiss. Map patterns and
outcrop information for the Milton Belt indicate that the metamorphic rock is broadly folded,
with foliation of moderate to gentle dips. Strikes for outcrops are variable, owing to the
generally flat-lying nature of the geologic structure; the regional strike is to the east-northeast
(Carpenter, 1982).

Triassic diabase dikes in the region, mapped on the basis of aeromagnetic surveys and occasional
outcrops, have consistent strikes of approximately 10 to 20 degrees west of north. Quaternary
alluvium is mapped in the larger drainages in the site vicinity, including Jacob’s Creek and its
tributaries.

2.2 Hydrogeology
Depth to groundwater has been measured in the monitoring wells at the site during each semiannual groundwater sampling event. The groundwater elevation at each well was calculated
relative to the surveyed measuring point (top of casing) for each monitoring well. Tables 1
summarize the groundwater elevations.

Groundwater elevation contours were interpreted from the October 2016 water level measurements to create the potentiometric surface map. Groundwater flow paths at the site converge on the creeks that bisect the site and border it to the west-southwest. Groundwater flow
beneath the Subtitle D Area Landfill is radial from the southeast to the north, northwest, and
west. The potentiometric surface contours for groundwater are shown on Drawing 1.

Horizontal groundwater gradients were estimated based on the October 2016 groundwater levels.
Gradients were estimated along groundwater flow path segments that intersect potentiometric surface contours (Drawing 1). These gradients are summarized in Table 2. The horizontal gradients were calculated as approximately 0.07 to 0.11 ft/ft for the Subtitle D area. These
gradients are consistent with previous gradient estimates (CDM, 1996; JOYCE, 1998).

Average hydraulic conductivities (K) from each slug-tested well were used to estimate average
linear groundwater flow velocities. Linear groundwater flow velocities for wells screened in saprolite were computed using the following modified Darcy equation:
V = Ki/n, where V = average linear velocity (feet/day), K = hydraulic conductivity (ft/day), i = horizontal
hydraulic gradient, and n = effective porosity.

The linear groundwater flow velocity estimates are 1.65 to 21.93 ft/day for the Subtitle D area as
shown in Table 2. These ranges are consistent with previous estimates (CDM, 1996; JOYCE, 1998). The linear velocity equation and resulting rates make the simplified assumptions of a homogeneous and isotropic aquifer. This equation can over-estimate velocities when applied to
heterogeneous and/or anisotropic conditions such as are believed to exist at this site. Site boring
logs record that regolith sampled at the site often exhibited the remnant foliation and other parent
rock textures. These characteristics can impart locally anisotropic groundwater flow directions.
The regolith and bedrock are hydraulically connected, but effective porosity typically declines markedly downward into underlying fractured bedrock (Harned, 1989).

3.0 FACILITY MONITORING HISTORY

The Subtitle D Landfill groundwater and surface water monitoring is completed in accordance
with NCSWMR § 1633 (groundwater) and § 0602 (surface water) Detection Monitoring Program
and the Water Quality Monitoring Plan for the facility. Groundwater and surface water samples are collected semiannually and analyzed for all constituents listed in NCSWMR Appendix I.
3.1 Groundwater Monitoring History

The groundwater monitoring network at the Subtitle D area consists of two
upgradient/background wells and twenty-two downgradient wells summarized in the following
table (MW-18 is monitored for static water level only). These locations are shown on Drawing 1.

Benzene and 1,2-dichloroethane (1,2-DCA) were detected in MW-19 for the first time in October 2011. Vinyl chloride was first detected in April, 2012. The concentration of benzene in MW-19 peaked in the December 2011 sampling event, and in the four subsequent sampling events it
steadily declined. In the April 2013 event, the concentration of benzene in MW-19 dropped to
below the groundwater protection standard found in 15A NCAC 2L.0202 (the NC2L Standard).
The concentrations of 1,2-DCA and vinyl chloride peaked in April 2012 and then declined in the

next two events to a level below their NC2L Standards. In the October 2012 sampling event, only benzene was detected above the NC2L Standard.

JOYCE believed, based on field observations, that the integrity of the seal in MW-19 may have
been compromised as a result of significant erosion in the area of the well; so prior to the
October 2012 sampling event, MW-19 replacement well MW-19R was installed. MW-19R is downgradient and about 20 feet closer to the Facility’s property line than MW-19 (see Drawing 1). At the request of NCDEQ, MW-19 was left in place following the installation of MW-19R,
and both wells were sampled.

An Alternate Source Demonstration (ASD) for the VOC detections in MW-19 was submitted in
April 2012. In February 2013, JOYCE submitted an Addendum to the April 2012 ASD. The April 2012 ASD and February 2013 Addendum are included in Appendix 1. The additional data submitted in the 2013 Addendum supported the conclusion of the April 2012 ASD that the likely
source of the VOCs was an isolated random release rather than an ongoing release from the
landfill. This was suggested by the sudden appearance and the rapid decline in concentration
since a peak at the time of first detection or shortly thereafter. The decline suggested that there
was not an ongoing source and that natural diffusion, dispersion, and biodegradation was successfully degrading the VOCs. On March 25, 2013, in a response to the ASD Addendum, NCDEQ concurred that the appropriate action at this point was to continue to monitor the decline
for two additional sampling events (April 2013 and October 2013) before requiring any
additional response actions.

All three detected constituents were below the applicable NC2L Standards during the April 2013 sampling event; however, in the October 2013 event, benzene exceeded the NC2L Standard in both MW-19 and MW-19R. Because this one data set represented a reversal of the prior
downward trend for benzene, JOYCE requested that the review period be extended an additional
two monitoring events (spring and fall 2014) before any decisions were made regarding the need
to enter into assessment monitoring.

Benzene was below the Solid Waste Section Reporting Limit (SWSL) and the NC2L Standard in both MW-19 and MW-19R in the April 2014 event; however, in the September 2014 event, benzene exceeded the NC2L Standard in both wells. In a phone conversation on November 13,
2014, Joyce discussed these results with Ervin Lane of NCDEQ, and it was agreed that since the
concentrations of benzene have fluctuated from just above to below the NC2L Standard over the
last few events, we could wait to see the results of the next event (spring 2015) before
determining whether to initiate Assessment Monitoring. Benzene concentrations in MW-19 and MW-19R were below the NC2L Standard in the March 2015 sampling event and were non-detect in the September 2015 sampling event; therefore, Assessment Monitoring was not required.

During the March 2016 water quality monitoring event, the initial laboratory data results
included exceedances of the NC2L Standard for benzene in MW-19 and benzene and vinyl
chloride in MW-19R. A verification sampling event was performed on May 9, 2016, the results

of which confirmed the benzene detection above the NC2L Standard in MW-19; however, the verification sampling refuted the benzene and vinyl chloride exceedances in MW-19R. MW-19R
is downgradient and closer to the Facility’s property line than MW-19 (see Drawing 1), so the
extent of the plume appears to be limited to within the facility property.

During the October 2016 water quality monitoring event, the initial laboratory data results included exceedances of the NC2L Standards for benzene in MW-19 and MW-19R. A verification sampling event was performed on December 5, 2016, the results of which confirmed
the benzene detections above the NC2L Standard in MW-19 and MW-19R. Historical
groundwater sampling results are included in Table 3

3.2 Surface Water Monitoring History Surface water monitoring at the Facility is completed in accordance with the NCSWMR and the
approved Water Quality Monitoring Plan. Surface water samples are collected semiannually and
analyzed for the constituents listed in NCSWMR Appendix I. The surface water monitoring
network includes one upstream surface water sampling point (SMP-3), three downstream surface
water monitoring points (SMP-1, SMP-2, and SMP-4), and one surface water monitoring point (SMP-5) located at the end of the underdrain from Phase 3 before entering the sediment trap. These locations are shown on Drawing 1.

Surface Point Classification Monitoring Program
SMP-1 Compliance Surface Water
SMP-2 Compliance Surface Water
SMP-3 Upstream Surface Water
SMP-4 Compliance Surface Water
SMP-5 Compliance Surface Water
Following Construction of the Phase 3 the outfall of the underdrain for Phase 3 (SMP-5) became buried and unable to be located; therefore, it had not been sampled. In September 2016, JOYCE
and the County excavated in the Area of SMP-5 and located the outfall of the underdrain.
SMP-5 was sampled for the first time since installation on September 27, 2016. SMP-5 was also
sampled during the second semiannual water quality monitoring event of 2016, on October 26,
2016. SMP-5 shows similar detections to those in MW-19 and MW-19R. With the exception of SMP-5, no VOCs have been detected at quantified concentrations in
surface water samples since December 1998. Historical surface water sampling results are
included in Table 4.

4.0 INVESTIGATIVE ACTIVITIES
4.1 Underdrain Area Excavation and Sampling

On September 26, 2016, JOYCE and the County excavated the area in which SMP-5 was located
in order to find the outlet of the underdrain. JOYCE and the County successfully uncovered the outlet of the underdrain, shown in the picture below.
JOYCE returned on September 27, 2016, to sample the outfall (SMP-5) and take soil samples in
the vicinity of the outfall. This laboratory data along with sampling forms are included in
Appendix 2 and summarized in the table below. A map showing the soil sample locations is
included as Drawing 2.

JOYCE compared the historical leachate data included in Table 5 to the sampling results of
MW-19, MW-19R and SMP-5. There has been no benzene, 1,2-DCA, or vinyl chloride detected
in the leachate; therefore, it is unlikely that the impacts seen in MW-19, MW-19R, and SMP-5 were from leachate released from the Landfill.
4.2 Landfill Gas Impact

When landfill gas is released from a solid waste disposal unit to the vadose zone and is in contact
with soil gas moisture or the water table, the VOCs in the landfill gas can partition from the gaseous phase to the dissolved phase in accordance with the ideal gas law and the constituent-specific Henry’s Law Constants (Baker, 1998; Carpenter et al, 1997). Infiltrating precipitation
will then carry the VOCs to the water table as recharge, or the partitioning may directly transfer
the VOCs to the water table. In instances where monitoring wells are screened above the water
table, landfill gas may enter the well casing and directly partition COC VOCs to the water in the
monitoring wells.
We believe the Phase 3 underdrain may provide a conduit for landfill gas to impact groundwater. The underdrain was constructed with of 6 inch slotted HDPE pipe, so the slots can allow the
landfill gas to enter the underdrain and directly partition the VOCs into the water. This impacted
water then flows through the underdrain to discharge near MW-19. This would account for the
VOCs detected in MW-19 and MW-19R.
Landfill gas odors were observed escaping from the outfall of the underdrain when it was sampled in September 2016. In order to provide additional evidence, JOYCE monitored the
drain outlet for the presence of Methane and installed caps on MW-19, MW-19R, and MW-20 to
allow the monitoring of the headspace for the presence of methane. Methane was measure using

a Landtec GEM 2000 portable gas analyzer. The results from the monitoring are summarized in the table below.

Location Date/Time Methane (% Volume) Static Pressure (psi)
Drain Outlet 10/25/16 11:36 AM 0.7 NA
Drain Outlet 11/9/16 10:00 AM 30 NA
Drain Outlet 11/22/16 3:51 PM 0 NA
MW-19 11/22/16 3:53 PM 1.8 0
MW-19R 11/22/16 3:54 PM 0.1 0.01
Drain Outlet 12/5/16 11:18 AM 2.9 NA

MW-19R 12/5/16 11:22 AM 0 0.02

On October 26, 2016, in conjunction with the second semiannual groundwater sampling event,
MW-19, MW-19R, and SMP-5 were sampled for dissolved methane, ethane, and ethene.
Methane was detected in high levels in all three locations, indicating impacts from landfill gas. The sampling results are summarized in the following table, and the laboratory report and field sampling logs have been included in Appendix 3.

Sample Location Dissolved Methane Dissolved Ethane Dissolved Ethene
MW-19 562 µg/L ND ND
MW-19R 1240 µg/L ND ND
SMP-5 1340 µg/L ND ND
Notes: ND = Not Detected; µg/L = Micrograms per liter.
These data and field observations support the contention that the VOCs detected in SMP-5,
MW-19 and MW-19R are a result of landfill gas impacts.

5.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the data and evaluations presented herein, it is apparent that leachate from the
Rockingham County Permit No. 79-04 Subtitle D MSW Landfill is not the source of the VOC
concentrations that have been detected in MW-19, MW-19R, and SMP-5. The data suggest that
the source of the VOCs in these monitoring points is partitioning from landfill gas as water moves through the underdrain and discharges near MW-19.
Based on the conclusion that landfill gas is impacting the Groundwater at the facility,
Rockingham County plans to initiate the following corrective measures:

 A concrete sump will be installed to collect the discharge from the outfall (SMP-5) so the
water can be tested, and if found to be impacted, pumped out and taken to the leachate
pond. Details of the proposed sump are shown on Drawing 3.

 Rockingham County will install gas vents in the landfill to allow the gas to vent,
providing a more preferential path of escape and reducing or eliminating migration along the underdrain. Proposed gas vent locations are shown on Drawing 4. In conjunction
with the partial closure of the landfill which is scheduled for FY 2018, the gas vents will
be converted into gas extraction wells and connected to the active landfill gas system.

Based on these conclusions, supporting statements, and Rockingham County’s plan for corrective
action, JOYCE, on behalf of Rockingham County is respectfully requesting that NCDEQ approve this ASD Addendum for past and future detections of VOCs in MW-19, MW-19R, and SMP-5. With NCDEQ’s approval of this ASD Addendum, the Rockingham County Landfill will
remain in the Detection Monitoring program.

Notes: All concentrations are in µg/L.
DL = Laboratory detection limit.
MW = Groundwater monitoring well.
QL = Quantiation limit
J = Estimated value between DL and SWSL.
B = Blank qualified detections.
ND = Not detected above laboratory reporting limit (October 1996 - June 2006). Not detected above the laboratory detection limit (December 2006 - Present).
'--- = Not Sampled and/or Not Reported.
NI = Not Installed. An NI designation indicates the well was not installed, exterior well construction not complete, not developed, or prior to background sampling.
NC 2L = North Carolina 2L Groundwater Standard.
GWPS = Groundwater Protection Standard.
Bold values are above the NC 2L Groundwater Standard or Groundwater Protection Standard (GWPS).
When the NC 2L Standard has not been established, the GWPS will substitute.
{ } = When Method Blank concentrations are higher than Trip or Field (Equipment) Blank concentrations and there are multiple Method Blanks for a sample set, use the brackets to assign Method Blank data to specific data sets.
