1. INTRODUCTION
On behalf of the City of Charlotte, Geosyntec Consultants of NC, PC (Geosyntec) has
prepared this Semi -Annual Monitoring Report, First Half 2019 for the City of Charlotte's
former York Road Landfill. This report presents the results through May 2019 of
groundwater, surface water, and methane monitoring conducted at the former landfill
since the previous Semi -Annual Monitoring Report (Geosyntec, 2018) was submitted in
November 2018.
1.1 Site Description and History
The former York Road Landfill (herein referred to as the "Site") is an approximately 400-
acre site located along West Tyvola Road and South Tryon Street (Highway 49) in
Charlotte, Mecklenburg County, North Carolina (Figure 1). The Site was operated as an
unlined municipal solid waste landfill from 1968 to 1986, with the last expansion
occurring in 1983 (under North Carolina Department of Environmental Quality
[NCDEQ] Facility Permit Number 60-03). The landfill waste placement area consisted
of a total of approximately 168 acres, which was divided into six cells referred to as
Landfill Areas A through F, as shown in Figure 2. The precise locations of waste
placement boundaries are uncertain and have been estimated based on historical drawings
by others and electromagnetic mapping. The former landfill was developed with the
construction of West Tyvola Road, a golf course, and a recreational park following
closure in 1986. Today, the Site is utilized by the Harry L. Jones, Sr. Golf Course
(formerly Renaissance Park Golf Course) and Renaissance Park, which includes
recreational facilities for softball, soccer, biking, and disc golf.
In July 2016, some of the athletic fields at Renaissance Park (including the softball and
soccer facilities) were closed to public use as a result of the effects of the former landfill
on upkeep of the fields. Select facilities associated with the softball and soccer fields
located on waste have been demolished in order to alleviate maintenance issues and risks
associated with the landfill (e.g., methane accumulation). Demolition activities were
mostly completed by April 2019 with the exception of additional grading and drainage
modifications. The Mecklenburg County Park & Recreation Department has indicated
that the portions of the park where demolition occurred will be utilized with a more
passive park use (e.g., open field or dog parks). Other Site facilities outside of the
demolition area including the golf course, bike trails, and disc golf courses remain in
operation.

1.2 Hydrovologic Setting
The Site is located within the Charlotte Belt of the Piedmont Physiographic Province.
The topography of the Piedmont Province is generally characterized by gently rolling
hills ranging in elevation from approximately 300 to 1,200 feet (ft) above mean sea level
(MSL), and the Site elevation ranges from approximately 580 to 680 ft above MSL.
Geologically, the province is comprised primarily of crystalline metamorphic rocks
(schists and gneiss, and to a lesser extent, phyllite and slate) of Precambrian to Paleozoic
age. These units are often highly deformed with multiple fracture and foliation planes,
which promote anisotropic groundwater flow. The occurrence and movement of
groundwater at the Site is typical of the Piedmont formation, and generally occurs within
two hydrogeologic units. A shallow hydrogeologic unit typically occurs within the soils
and saprolite (weathered residuum which mantles bedrock). A deeper hydrogeologic unit
is generally associated with secondary porosity (fractures or open spaces) within the
crystalline bedrock. A transition zone of fractured bedrock occurs between saprolite and
bedrock and is generally referred to as partially weathered rock (PWR).
Groundwater flow in the shallow hydrogeologic unit is controlled by local topographic
features, where recharge occurs in upland areas and discharge occurs in drainage features
such as streams, rivers, or lakes. Recharge to the shallow hydrogeologic unit is primarily
the result of infiltrating precipitation. Groundwater flow in the deeper water -bearing zone
is controlled by the distribution and degree of interconnection of openings in the rock.
1.3 Regulatory Authority
The York Road Landfill was closed under the 10 NCAC 10G, Section .0500 rules as
referenced in the 21 August 1987 closure letter from the North Carolina Department of
Human Resources, Division of Health Services. These regulations were transferred and
recodified into title 15A NCAC 13B Section .0500, effective April 1990.
Water quality and landfill gas monitoring at the Former York Road Landfill is conducted
pursuant to the Water Quality and Landfill Gas Monitoring Plan ("Monitoring Plan";
Geosyntec, 2017), which was approved by the North Carolina Department of
Environmental Quality (NCDEQ) in a 7 March 2017 letter. The Landfill Gas Sampling
Schedule from this Monitoring Plan, presented in Table 1, has been revised to remove
demolished light poles and score boards, as well as remaining large light poles which are
not located on waste, where methane has not been observed historically. Groundwater

consultants
and surface water sampling is conducted semi-annually, typically in March and
September.
As stated in the Monitoring Plan, the 15A NCAC 13B Section .0500 rules and closure
letter for the Site do not specify landfill gas monitoring requirements. Therefore, landfill
gas monitoring is regularly conducted in general accordance with the Monitoring Plan,
which was developed to provide reasonable protection to public health and the
environment. Landfill gas monitoring is conducted on a quarterly basis (typically in
January, April, July, and October).

2. MONITORING ACTIVITIES AND FIELD METHODOLOGY
The following sections describe the field methodology for groundwater, surface water,
and methane monitoring conducted during the current reporting period.
2.1 Groundwater Monitoring
Groundwater monitoring was conducted pursuant to procedures in the Monitoring Plan.
The current monitoring network includes twenty-three (23) groundwater wells (21
monitoring wells and 2 water supply wells), with sixteen (16) groundwater wells included
in the sampling network pursuant to the Monitoring Plan (the remaining seven [7]
groundwater wells are used for water level measurements only). Wells are screened
across one or more of the three hydrogeologic units at the Site (saprolite, PWR, and
bedrock). Monitoring well construction details are listed in Table 2, and locations are
depicted in Figure 2. A schedule for sample collection and associated laboratory analyses
conducted for each well under the Monitoring Plan is listed in Table 3.
Groundwater sampling activities conducted during this reporting period were performed
from 14 March through 5 April by Pace Analytical Services (Pace) of Charlotte, NC.
Groundwater level measurements from groundwater wells that are part of the monitoring
network were collected during a single day (on 14 March 2019) in order to evaluate the
potentiometric surface and groundwater flow direction at the time of measurement.
Sampling of the Site wells was performed with dual -membrane passive diffusion bags
(PDBs) capable of sampling for both volatile organic compound (VOC) and metals
analysis. PDB sampling was conducted in two mobilizations. During the first
mobilization to the Site on 14 March 2019, PDBs were deployed in each well at the
approximate midpoint of the screened interval, or the midpoint of the water column if the
screen was not fully submerged. Prior to deployment, each PDB was filled with
laboratory -grade deionized water. PDBs were hung using a decontaminated stainless -
steel weight and stainless -steel wire or disposable, inert cord. The PDBs were allowed
to equilibrate within the wells for at least 21 days, providing time for constituents within
the wells to diffuse across the PDB membranes, and to allow for vertical equilibration of
constituents within the PDBs.
During a second mobilization on 5 April 2019, the water level and PDB depths were
measured prior to sampling to confirm PDB placement. PDB samplers were recovered

by pulling them up with the wire or cord. The bags were then pierced with a disposable,
small -diameter discharge tube and water was transferred to the laboratory -provided
sample containers.
After sampling, groundwater parameters (temperature, pH, and specific conductance)
were measured with a daily -calibrated multimeter from remaining water in the PDBs, or
from bailed water if insufficient volume was available in the PDBs. Samples were
transported to the laboratory on ice, under chain -of -custody. Non -dedicated sampling
equipment was decontaminated in accordance with procedures described in the
Monitoring Plan. Field quality assurance/quality control (QA/QC) samples including a
field (rinsate) blank, a trip blank, and a field duplicate (from parent sample DMW-06)
were analyzed. Field data sheets for groundwater sampling efforts are included in
Appendix A.
2.2 Surface Water Monitorin
Surface water monitoring was conducted pursuant to procedures described in the
Monitoring Plan. The surface water monitoring system consists of six sample locations
(listed in Table 3 and depicted on Figure 2) on the three streams that cross the Site: Sugar
Creek (SC), and two unnamed tributaries referred to as the north tributary (NT), and the
south tributary (ST). Sample locations generally correspond to one upstream location
and one downstream location from each stream. Laboratory analyses conducted for each
surface water sample location are listed in Table 3.
Surface water monitoring during the current reporting period was conducted on 5 April
2019 by Pace. Samples were collected from locations where flow was occurring (where
possible) and from locations away from the stream bank to minimize disturbance to the
stream bed. Samples were placed in laboratory -provided sample containers and
transported to the laboratory on ice, under chain -of -custody. Field measurements of pH,
specific conductance, and temperature were recorded for each sample at the time of
collection. Field data sheets for surface sampling efforts are included in Appendix A.
2.3 Water Supply Wells
Sampling of water supply wells WSW-2 and WSW-3 was not carried out during this
monitoring period. Annual sampling of these wells is anticipated to occur in September
2019 pursuant to the sampling schedule in the Monitoring Plan (presented in Table 3).

2.4 Methane Monitoring
2.4.1 Routine Methane Monitoring Activities
Methane monitoring was carried out pursuant to the Monitoring Plan. Methane
monitoring activities include quarterly measurement of landfill gas concentrations at
methane probes, active extraction systems, and other points where methane could
accumulate such as storm drains. Table I lists points that are the subject of quarterly
methane monitoring. Passive structures and Site features that are part of the methane
monitoring program are depicted in Figures 3A and 3B. In addition to methane
monitoring, methane alarm systems and active extraction systems are periodically
inspected and maintained. Quarterly methane monitoring events during this reporting
period were carried out by Geosyntec from 21 through 23 January and 22 through 24
April 2019.
Annual inspection and maintenance of the three methane detection systems (located in
the golf course clubhouse, golf course maintenance building, and softball field concession
building) was conducted by Lefler Electronics, Inc. (LEI Systems) on 22 April 2019.
These systems consist of 36 Macurco GD-2A detectors connected to control panels and
audible alarms which notify authorities and occupants in the event of methane detection.
Additionally, stand-alone, plug-in First Alert Model GCO 1 CN methane detectors are
located in the John Crosland School, the Leatherman maintenance building, and golf
course chemical storage building. Operation of these detectors was confirmed by visual
inspection during quarterly monitoring events.
Operation of the three active extraction systems (clubhouse, northeast boundary trench
system, and northeast boundary landfill gas migration control system) was observed by
Geosyntec during quarterly monitoring events. Effluent methane concentrations, blower
vacuum, air flow rates, and blower operating hours were recorded, where possible.
Visual inspection of the landfill cap was conducted pursuant to the Monitoring Plan
during quarterly monitoring events in January and April 2019. The purpose of the visual
inspections is to identify areas of concern such as significant settlement, formation of
subsurface voids, locations of methane venting, odors, distressed vegetation, or exposed
waste.

Demolition activities in 2018 and early 2019 removed large light poles and scoreboards
located on waste, along with associated foundations. As a result, routine monitoring now
excludes these demolished points, as well as remaining large light poles which are not
located on waste, where methane has not been observed historically. The Landfill Gas
Sampling Schedule presented in Table 1 specifies which monitoring points are no longer
monitored as a result of demolition.

3. MONITORING RESULTS
The following sections describe the results of groundwater, surface water, and methane
monitoring conducted during the current reporting period.
3.1 Groundwater
3.1.1 Potentiometric Surface Elevation and Groundwater Flow Direction
Static groundwater elevations measured on 14 March 2019 and historical groundwater
elevations are listed in Table 4. Figure 4 displays a potentiometric surface map and
inferred groundwater flow direction for the Site. Groundwater within the saprolite and
shallow bedrock aquifer generally flows toward the southwest, following the surface
topography toward Sugar Creek. The potentiometric gradient is approximately 0.013 ft/ft
across the Site. The flow direction observed on 14 March 2019 was generally consistent
with historical observations at the Site. Groundwater elevations in March 2019 were on
average 1.5 feet higher than historical averages recorded since 2006 and several wells
(DDW-03A, DDW-06, DMW-02, DMW-B, YRW-06A, YRW-07, and YRW-11B) had
the highest groundwater elevation observed since March 2006 with water levels up to 3
ft or more above average. This can likely be attributed to elevated rainfall throughout the
fall of 2018 and winter of 2019. The water level recorded at DMW-02A was only 2.44
ft below the top of casing, and water was visually observed by the field crew. DMW-
02A is generally not representative of static conditions and is not included in
potentiometric contouring.
3.1.2 Groundwater Analytical Results
A summary of detected constituents and field parameters (pH, specific conductance, and
temperature) from monitoring well and water supply well samples collected during the
April 2019 groundwater sampling event is included in Table 5 and laboratory analytical
reports are included in Appendix B.
Low levels of some volatile organic compounds (VOCs) and metals were detected in
samples collected from Site monitoring wells in April 2019. Select compounds were
detected in several wells at concentrations above the Title 15A North Carolina
Administrative Code (NCAC), Subchapter 2L Standards (2L Standards). One or more
VOCs exceeded their 2L Standard in 8 of the 14 groundwater monitoring wells sampled,
and one or more metals were detected above their 2L Standards in 3 of the 14 wells

sampled. Figure 5 displays a map with exceedances of the 2L Standards shown for each
well. The April 2019 analytical results reveal the following:
• 1, 1 -Dichloroethane was detected above its 2L Standard of 6 micrograms per liter
(µg/L) in one well, DDW-02 at 8.6 µg/L.
• 1,2-Dichloropropane was detected above its 2L Standard of 0.6 µg/L in two wells,
DDW-03 at 1.8 µg/L and DMW-06 at 2.2 µg/L.
• Benzene was detected above its 2L Standard of 1 µg/L in four wells, DDW-OlA
at 6.2 µg/L, DDW-03 at 2.6 µg/L, DDW-03A at 3.9 µg/L, and DMW-02B at 5.0
µg/L.
• Trichloroethene (TCE) was detected above its 2L Standard of 3 µg/L in three
wells, DDW-01 at 4.9 µg/L, DDW-OIA at 4.4 µg/L, and DMW-06 at 4.6 µg/L.
• Tetrachloroethene (PCE) was detected above its 2L Standard of 0.7 µg/L in three
wells, DDW-01 at 4.2 µg/L, DDW-OIA at 1.7 µg/L, and DMW-06 at 1.1 µg/L.
• Vinyl chloride was detected above its 2L Standard of 0.03 µg/L in four wells,
DDW-01 A at 1.2 µg/L, DDW-03 at 2.9 µg/L, DMW-01 at 1.1 µg/L, and DMW-06
at 3.0 µg/L.
• Barium was detected above its 2L Standard of 700 µg/L in one well, DMW-02A
at 1,390 µg/L.
• Cadmium was detected above its 2L Standard of 2 µg/L in two wells, DDW-02 at
2.5 µg/L and DMW-01 at 27.2 µg/L.
• Mercury was detected above its 2L Standard of 1 µg/L in one well, DDW-02 at
2.3 µg/L.
Historic groundwater analytical data are included in Appendix C.
A statistical analysis of the monitoring well VOC data was performed to identify
groundwater quality trends. The Mann -Kendall non -parametric test was performed on
performance monitoring wells for each VOC with a concentration above the 2L Standard
in April 2019, and where less than half of data points in the data set were non -detect. The
GC5699D\CAR190010 9 05.2019

Semi -Annual Monitoring Report — First Half 2019 Ge o sptec

Mann -Kendall test was utilized to evaluate whether the concentration of each VOC
exhibits a statistically significant increasing or decreasing trend at a given confidence
interval; for this evaluation, a confidence interval of 95% was applied. EarthScience
Information Systems' Esdat Version 5.1 software was used to perform the trend analysis.
EPA guidance on statistical analyses for groundwater data has indicated that a
concentration value lower than any of the detected measurements should be assigned
when an analytical result is "non -detect" (EPA, 2009). Therefore, zero values were
assigned to non -detects in this analysis.
Table 6 presents the results of the trend analysis for VOCs. This analysis was performed
on data collected since March 2008, which were readily available in the Site's database.
The results of the Mann -Kendall trend analysis are summarized as follows:
• Nine (9) decreasing VOC concentration trends are considered statistically
significant at 95% confidence, compared to four (4) upward trends.
• Four increasing VOC concentration trends are considered statistically significant
at 95% confidence (TCE at DDW-01, benzene at DDW-0IA, 1, 1 -dichloroethane
at DDW-02, and benzene at DMW-02B).
• One (1) VOC was found to have no statistically significant trend at a 95%
confidence interval (benzene in DDW-03).
Three compounds were not included in the Mann -Kendall trend analysis where more than
half of data points in the data series were non -detect; DDW-01A TCE, DDW-01A vinyl
chloride, and DDW-03A benzene. These series were excluded from the analysis as the
Mann -Kendall is not considered appropriate in evaluating trends when more than half of
data points are non -detect. Decreasing concentration trends for all but five of the VOCs
analyzed provides statistical evidence of the overall improvement to the groundwater
quality for VOCs at the Site as a result of natural attenuation processes.
One VOC decreased to below the 2L standard at a well which had an exceedance in
September 2018. At DMW-01, benzene dropped back below the 2L standard and the
method detection limit after a single exceedance since September 2015.
Five compounds increased above the 2L standard since the September 2018 sampling
event: TCE at DDW-01, TCE and PCE at DDW-01A, vinyl chloride at DDW-03, and
GC5699D\CAR190010 10 05.2019

cadmium at DDW-02. TCE concentrations have historically fluctuated at DDW-01 and
DDW-OIA since approximately 2014 though the March 2019 concentration at DDW-01
is slightly higher than the historical maximum. PCE at DDW-01A has been non -detect
since March 2014 when a concentration of 6.7 µg/L was detected. This increased PCE
concentration at DDW-01A may be related to release of mass from the unsaturated zone
due to an elevated water table which was also present in March 2014. Vinyl chloride has
been detected at similar concentrations in DDW-03 as recently as 2017 and this well is
still exhibiting a downward trend based on the Mann -Kendall evaluation presented in
Table 6. The 21, standard exceedance of cadmium at DDW-02 is the first historical
exceedance of this analyte at this well, though the concentration during the September
2018 monitoring round was also elevated.
The historical presence of chlorinated daughter products of PCE (TCE, cis-1,2-DCE, and
VC) in wells may indicate that some reductive dechlorination has occurred in Site
groundwater, which can occur naturally under favorable (generally anaerobic) conditions.
These biodegradation processes, in combination with other natural processes including
sorption, dilution, and chemical degradation, contribute to natural attenuation of VOCs
in groundwater and reductions in concentrations over time.
Field parameter measurements were generally consistent with historical ranges. pH
values were measured within a range of 4.8 and 8.2, with the exception of DMW-02A,
with a pH value of 12.3. The pH at DMW-02A has typically been higher than other wells,
which is potentially attributable to cement grout used in well construction. Specific
conductance ranged from 54 to 1,555 microsiemens per centimeter (µS/cm), with the
exception of DMW-02A (6,891 µS/cm) which has also exhibited high specific
conductance historically. At DMW-01, specific conductivity was only 54 µS/cm and pH
4.8 standard units. Historically, specific conductivity has been 318 µS/cm or higher at
this well and pH has been above 5.7 standard units. Temperature was also below
historical minimum during the March 2019 sampling round.
3.2 Surface Water
A summary of detected constituents and field parameters (pH, specific conductance, and
temperature) from samples collected during the April 2019 surface water sampling event
is included in Table 7, and laboratory analytical reports are included in Appendix B.

Trace levels of barium were detected in all six surface water samples collected during the
5 April 2019 sampling event, at concentrations below its Title 15A NCAC Subchapter
2B Water Supply Standard (2B Standard) of 1,000 µg/L. Lead was detected below the
2B Standard of 14 µg/L in two surface water samples, SC-1 and SC-2. Chromium (III
and IV) was detected above the 2B Standard of 11 µg/L in two surface water samples,
SC-1 and SC-2, with concentrations of 15.4 µg/L and 12.8 µg/L, respectively. Though
there have been historical detections of chromium in these samples, the April 2019 data
represent the first chromium 2B Standard exceedance since at least 2008. SC-1 is located
in Sugar Creek approximately 1,250 feet north of the North Tributary which acts as a
northern boundary of former landfill influence (Figure 2). The decrease of metals
concentrations from SC-1 to SC-2 which includes the portion of Sugar Creek along the
landfill boundary as well as the lack of chromium detections in groundwater samples
suggest that these concentrations are likely unrelated to buried waste. Location SC-1 is
upstream of stormwater influence from the demolition work conducted at Renaissance
Park. No VOCs were detected in surface water samples during the April sampling event.
Field parameter results were generally consistent with historical ranges except specific
conductance which was below 100 µS/cm at each location with the exception of NT-2.
pH ranged from 6.6 to 7.5 and specific conductance ranged from 44.2 to 187.0 µS/cm.
Specific conductance in the surface waters has been historically between 92 and 510
µS/cm with the exception of a September 2011 measurement of 722 µS/cm at ST-1. The
low specific conductance in April 2019 may be a result of instrument error.
3.3 Methane
Results of methane monitoring at locations with detections above 0.1 % methane from
January 2018 through April 2019 are summarized in Table 8, and landfill gas monitoring
results from December 2018 through April 2019 at monitored locations are included in
Appendix D. Historical landfill gas data from January 2012 through April 2019 is
included in Appendix E. The following sections discuss these results.
3.3.1 Passive Methane Monitoring Points
Passive methane probe monitoring results from the most recent monitoring event (April
2019) are displayed in Figure 6 (northeast and northern boundaries) and Figure 7 (South
Tryon Street and Sugar Creek boundaries). Methane concentrations at select subsurface
monitoring probes exceeded the LEL of 5% along the South Tryon Street boundary, the

northern boundary, and northeast boundary during the January and April 2019 monitoring
events. Methane was not detected in probes along Sugar Creek on the western boundary.
No LEL exceedances were observed in off -Site probes during this reporting period.
Historically, seven LEL exceedances have been observed in probes located across South
Tryon Street (P-1 through P-4) since 2011. The April 2019 concentration of methane at
P-1 was 4.5% but the prior two measurements in this probe were 0.3% and 0.0% in
January 2019 and October 2018, respectively. In April 2019 it was discovered that
methane probe P-4 had been paved over and a measurement could not be collected. This
probe will be re -exposed prior to the next monitoring event and the area will continue to
be monitored to evaluate the potential for off -Site migration at the South Tryon Street
boundary.
On -site probes along the northern boundary have had methane concentrations above the
LEL during the January 2019 (probes 41 through 43) and April 2019 (probes 41 through
44) monitoring events. These probes are located approximately 300 feet from the
expected waste boundary. Possible causes of methane in the northern boundary probes
could include: i) an isolated area of waste in the vicinity of the probes; ii) a migration
pathway through the subsurface; iii) migration through a preferential conduit (e.g., storm
drain). These probes are located approximately 450 feet from the northern property
boundary. In addition, the north tributary likely serves as a hydraulic barrier for landfill
gas as the water table elevation near this waterway has been measured between 0.5 feet
and 2.5 feet below ground surface.
Occasional elevated concentrations of methane at select off -Site probes near the northeast
boundary during the past few years indicate off -Site migration of methane above the LEL
may have been occurring in the subsurface. A supplemental landfill gas migration control
system was constructed along the northeast boundary and began operating in September
2017. No off -Site exceedances of the LEL were observed near the northeast boundary
during this reporting period. The maximum off -Site concentration observed during the
reporting period was 0.2% which suggests the active extraction systems are working
effectively. in S-7 in July 2018. Possible causes of continuing off -Site methane could
include; i) a migration pathway through the subsurface past the active extraction systems;
ii) migration through a preferential conduit (e.g., storm drain); or iii) an off -Site source
of methane.

Table 9 presents landfill gas concentrations and vacuum measurements from select
probes near the northeast boundary during the reporting period. Probe pairs VMP-06,
VMP-07, and VMP-08 (shallow and deep) can be used to interpret vacuum influence at
different locations along a common cross section between the Landfill Area D and off -
Site probe S-7, where methane has occasionally been detected. Vacuum influence has
not been measured in these probes during this reporting period. Methane and vacuum
data from these probes does not present clear migration pathway in the shallow or deep
zones. Considering that the LEL has not been exceeded in off -Site wells since installation
of these wells, it is recommended to continue monitoring to allow for interpretation of
possible migration pathways in the case that significant off -Site migration is observed.
Methane was not detected above 25% of the LEL inside structures including buildings
and storm drains monitored during this period. As light poles and scoreboards have been
either demolished or removed from the monitoring plan, no LEL exceedances were
observed in the subsurface in the vicinity of light poles or scoreboards during this
reporting period.
3.3.2 Active Extraction Systems
3.3.2.1 Golf Clubhouse System
The golf clubhouse venting system utilizes a five -horsepower Rotron regenerative blower
to extract methane from the clubhouse sub -slab gravel base using a combination of 31
horizontal, open-ended, PVC pipes grouped together into seven manifolds and eight
vertical extraction points installed just below the building floor slab. In addition, nine
vertical passive air infiltration vents are situated at regular intervals along the northern
and southern sides of the clubhouse. These perforated pipes allow atmospheric air to be
pulled into the subsurface to minimize pulling additional methane into the building from
nearby landfill areas. The ability to pull in ambient air lessens the magnitude of the
vacuum being applied to the surrounding soils and adds clean dilution air. The clubhouse
venting system layout is shown in Figure 8.
The clubhouse active extraction system was observed to be operating during both the
January and April 2019 landfill gas monitoring events. Methane measurements from
several points along the system that were recorded during landfill gas monitoring are
included in Appendix D.

No alarms have occurred during this reporting period, as reported by blower system
telemetry.
3.3.Z2 Northeast Boundary Trench Collection System
The northeast boundary trench collection system utilizes a 7.5-horsepower Rotron
regenerative blower, which removes methane vapors from an approximately 17-foot
deep, 1,400-foot long interceptor trench originally installed in 1990. The trench was
backfilled with gravel, and a bentonite/compacted soil cap was added to the top of the
trench to help limit atmospheric air infiltration. A four -inch diameter, corrugated,
perforated pipe was installed in gravel, 3 to 4 ft above the base of the trench. Initially,
four solid -walled, vertical PVC monitoring points (SU-0 to SU-3) were installed into or
near the trench. An additional 4-inch diameter solid walled PVC bypass line was installed
in July 1995 to address potential off -site methane migration in the northern portion of the
trench. SU-4 was installed at this time as an access point to clean this line. The system
was fitted with separate below grade valves that allow methane removal to be focused on
the mid -northern section of the trench.
In the fall of 2008, the City modified the system by installing six vertical extraction wells
(SU-5 through SU-10) and two other converted vertical wells (SU-1 and SU-2). Valves
were placed on each well to control and improve landfill gas extraction along the
northeast landfill boundary. A condensate (moisture) drain was installed on 29 January
2009, to drain the excess water that accumulated due to the 2008 revision to the extraction
system.
The northeast boundary trench extraction system was observed to be operating during
both the January and April 2019 landfill gas monitoring events and ran approximately
100% of the time between the October 2018 and April 2019 monitoring events based on
the blower's hour meter.
Methane monitoring results from active systems on the northeast boundary from the most
recent monitoring event (April 2019) are displayed in Figure 9. Figure 10 displays the
valve status, applied vacuum, air flow, and methane concentration at the trench system
vacuum extraction points as observed in April 2019. This figure shows that the system
is configured such that vacuum is focused on the middle section of the trench, which also
corresponds to the highest methane concentrations historically measured within the
trench. Air flow measurements were also taken at each active extraction well. The sum

Semi -Annual Monitoring Report — First Half 2019 Ge o spt c

of the measurements indicates the total system air flow rate was approximately 445
standard cubic feet per minute (scfm) during the April 2019 monitoring event. Wellhead
vacuum levels ranged from 2.1 to 3.2 inches of water at active wells, and methane was
not detected at the extraction wells in April 2019. The decrease in trench methane
concentrations since fall 2017 compared to historical concentrations is likely due to the
influence of the new landfill gas migration control system, which operates at a higher
vacuum than the trench system. Previous system evaluations have demonstrated that
vacuum influence from the trench system is not achieved outside of the gravel -filled
trench.
3.3.2.3 Northeast Boundary Landfill Gas Migration Control System
The northeast boundary landfill gas migration control system was designed to extract
from perimeter control (PC) wells screened at depths between the bottom of the trench
(approximately 17 feet below ground surface [ft bgs]) and the water table (approximately
30 to 40 ft bgs).
The landfill gas migration control system consists of 26 active PC wells placed in a line
along the northeast boundary connected to a blower system through buried laterals and a
header pipe. The system began operation in September 2017.
The northeast boundary landfill gas migration control system utilizes a skid -mounted
Roots 59 positive displacement blower, operating with three phase 230/460 V power and
capable of a maximum of 15 inches of mercury vacuum. This blower removes methane
vapors from an approximately 1,000 ft transect with 26 PC wells, each installed to total
depths between 30 and 40 ft bgs.
The northeast boundary landfill gas migration control system was observed to be
operating during both the January and April 2019 landfill gas monitoring events and ran
approximately 100% of the time between the October 2018 and April 2019 monitoring
events based on readings from the system's hour meter.
Figure 9 shows the locations of PC wells and methane concentrations observed in system
PC wells in April 2019. Figure 11 displays the applied well vacuum and flow at each
point, along with the methane and carbon dioxide concentrations observed on 22 April
2019. The sum of PC well flow measurements indicates the total system air flow rate
was approximately 337 scfm during the April 2019 monitoring event, and wellhead

vacuum levels ranged from 21.3 (PC-10) to 64.0 (PC-4) inches of water at active wells.
Flow rates ranged from 9.1 scfm (at PC-14) to 20.8 scfm (PC-10). Methane
concentrations ranged from 0.0% (at several wells) to 44.6% (PC-5) and were observed
to be greatest toward the northern half of the system (PC-1 through PC-5), and lower in
the southern half of the system (PC-6 through PC-26).
3.3.3 Methane Detection Systems
Methane detectors were confirmed to be active (by observation of a green status indicator
light) by Geosyntec during quarterly landfill gas monitoring events. The results of
inspection and maintenance of the three methane detection systems (golf course
clubhouse, golf course maintenance building, and softball field concession building)
conducted by LEI Systems on 22 April 2019 showed that these systems were functioning
properly. One outside speaker probe at the golf course maintenance building was not
functioning and has since been replaced. The next annual inspection of these systems is
scheduled for April 2020. No alarms were reported from the plug-in methane detectors
located within the Leatherman maintenance building, golf course chemical storage
building, and the John Crosland School. No methane alarms were triggered in the softball
field concession stand, golf course clubhouse, or the golf course maintenance building
during this reporting period.
No methane alarms in the clubhouse have occurred since upgrades to the clubhouse sub -
slab system were completed in May 2018. Telemetry and upgraded controls have
increased system reliability and allowed for notification of issues and faster resolution.
In January 2019 there was a fault in the golf course maintenance building system which
caused an alarm. Upon inspection, the fault was determined to be from a broken methane
alarm power board in the main garage. This power board was replaced by LEI systems
in early February 2019.
3.3.4 Landfill Cap Inspection and Repairs
Visual inspections of the landfill cap were completed by Geosyntec during quarterly
monitoring in January and April 2019. Since the demolition of the light poles and
scoreboards in November 2018, the landfill cap was observed to be generally intact, with
the exception of some voids next to storm drains that were beyond the demolition work
area. No methane was detected above the LEL in subsurface cracks or voids (Appendix
D).

In July 2016, some of the athletic fields at Renaissance Park (including the softball and
soccer facilities) were closed to public use. Mecklenburg County Park and Recreation
reported that ongoing settlement of the former landfill affected upkeep of the fields.
Demolition of the soccer field and softball field infrastructure located on waste was
completed between October 2018 and April 2019 with the exception of select grading
and drainage modifications.
Demolition activities included removal of the following site features:
• Thirty-four (34) light poles (all soccer field light poles and some softball field
light poles);
• Five (5) scoreboards (softball fields);
• Soccer field concession building and transformer;
• Picnic shelter (near soccer fields);
• Ticket booth (softball fields);
• Select sidewalks and retaining walls;
• Select softball field features (dugouts, bleachers, fencing, etc.);
• Utilities including electrical, sewer, and water associated with the above features;
and
• Landscaped vegetation in the area of above features;
Following demolition, the site is undergoing restoration to establish positive stormwater
drainage to existing stormwater infrastructure (which will remain in place and may be
modified, as necessary). As discussed in Section 2.4.1, routine landfill gas monitoring
no longer includes large light pole and scoreboard monitoring. Table 1 has been updated
to reflect this change.

4. SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS
The following sections summarize findings, conclusions, and future recommendations
based on data collected during this reporting period, and historical data collected at the
Site.
4.1 Groundwater
• Groundwater elevations were approximately 1.5 feet higher than historical
averages. Seven wells had the highest groundwater observed since at least March
2006 with groundwater elevations up to 3 feet or more above average. In addition,
the depth to water recorded and observed at DMW-02A was only 2.44 feet below
top of casing.
• Groundwater flow at the site was generally consistent with historical observations,
with a primary flow direction to the southwest toward Sugar Creek.
• Relatively low levels of VOCs were present in Site groundwater during
monitoring conducted in April 2019. One or more VOCs exceeded their 2L
Standard in 8 of the 14 wells sampled. VOCs exceeding the 2L Standard in at
least one Site well were 1,1-dichloroethane, 1,2-dichloropropane, benzene, TCE,
PCE, and vinyl chloride.
• Low levels of metals were present in Site groundwater during monitoring
conducted in April 2019. One or more metals were detected above their 2L
Standard in 3 of the 14 wells sampled. Metals exceeding the 2L Standard in at
least one Site well were barium, cadmium, and mercury.
• A trend analysis of groundwater VOC data since 2008 indicated that decreasing
trends are present for 9 of 14 VOC constituents analyzed. These trends provide
evidence that natural attenuation processes are reducing groundwater VOC
concentrations at the Site. One VOC, benzene at DMW-01 dropped below its
respective 2L Standard since the September 2018 sampling event. Five
compounds, TCE at DDW-01, TCE and PCE at DDW-01A, vinyl chloride at
DDW-03, and cadmium at DDW-02 exceeded their 2L Standards in April 2019
but not in September 2018.

4.2 Surface Water
Barium was detected at all six sampled surface water locations and lead in two surface
water locations at concentrations below their respective 2B Standards. Chromium (III
and IV) was detected above its 2B Standard in two locations (SC-1 and SC-2). The
decrease of metals concentrations from SC-1 to SC-2 which includes the portion of Sugar
Creek along the landfill boundary as well as the lack of chromium detections in
groundwater samples suggest that these concentrations are likely unrelated to buried
waste. No VOCs were detected in surface water samples collected in April 2019.
4.3 Methane
• Methane concentrations in off -Site subsurface monitoring probes near the
northeast boundary and South Tryon Street boundary did not exceed the LEL
during the monitoring period between October 2018 and April 2019.
• Methane was not detected above 25% of the LEL in monitored structures during
the reporting period. Methane was not detected above the LEL in the subsurface
in cracks and/or voids. Light poles and scoreboards located on waste were
demolished prior to this reporting period.
• Methane concentrations at select subsurface monitoring probes exceeded the LEL
at on -Site locations along the South Tryon Street boundary, northern boundary,
and northeast boundary. Methane was not detected in probes along Sugar Creek.
4.4 Additional Activities
The following additional activities took place during this reporting period:
• Demolition of park infrastructure associated with the soccer and softball fields
and located on waste was performed to alleviate maintenance issues and reduce
risks associated with methane. Demolition began in October 2018 and was
completed in April 2019 with the exception of select grading and drainage
modifications.

4.5 Future Work
• Off -Site LFG monitoring location P-4, located across South Tryon Street from the
Site, was inadvertently covered by asphalt when this area was repaved. This probe
will be exposed from beneath the pavement and continue to be monitored during
future landfill gas monitoring events.
• Methane has not been detected above the LEL in off -site probes along the
northeast boundary since January 2018, therefore, landfill gas monitoring at the
northeast boundary will be reduced to quarterly, as described in the monitoring
plan.
• On -Site LFG monitoring locations 41 through 44 will continue to be monitored
following LEL exceedances observed in January 2019 and April 2019.
• The monitoring plan is proposed to be modified by removing monitoring of park
large light poles and scoreboards as indicated in Table 1.
