1. INTRODUCTION
On behalf of the City of Charlotte, Geosyntec Consultants of NC, PC (Geosyntec) has
prepared this Semi-Annual Monitoring Report, First Half 2017 for the City of Charlotte’s
Former York Road Landfill. This report presents the results through April 2017 of
groundwater, surface water, and methane monitoring conducted at the former landfill
since the previous Semi-Annual Monitoring Report (Geosyntec, 2016) was submitted in
November 2016.
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 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. The precise locations of waste
placement boundaries are uncertain and have been estimated by others, as shown in
Figure 2. 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 Renaissance Park Golf Course and Renaissance Park, which include recreational
facilities for golf, 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. Other
facilities including the golf course, bike trails, and disc golf courses remain in operation.
1.2 Hydrogeologic 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
Semi-Annual Monitoring Report – First Half 2017 Former York Road Landfill, Charlotte, North Carolina
May 2017

GC5699B\2017 May York Road Report 2 05.2017
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, formerly North Carolina Department of Environment
and Natural Resources [NCDENR]) in a 7 March 2017 letter. Groundwater 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 does 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).
This represents the first Monitoring Report submitted under the 2017 Monitoring Plan.
Previously, groundwater monitoring was conducted pursuant to the Water Quality

May 2017

GC5699B\2017 May York Road Report 3 05.2017
Monitoring Plan (Delta, 2004), and landfill gas monitoring was conducted pursuant to
the Landfill Gas Monitoring Plan (HDR, 2011).

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 seventeen (17) groundwater wells
included in the sampling network pursuant to the Monitoring Plan (the remaining six [6]
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 1, 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 2. Pursuant to the
sampling schedule in the Monitoring Plan (presented in Table 2), total iron and
manganese were not sampled in March 2017. Sample analysis for total iron and
manganese for specified groundwater wells is scheduled to be conducted in September
2017.
Groundwater sampling activities conducted during this reporting period were performed
from 3 March through 28 March 2017 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 3 March 2017) 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 3 March, 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
Semi-Annual Monitoring Report – First Half 2017 Former York Road Landfill, Charlotte, North Carolina
May 2017

GC5699B\2017 May York Road Report 5 05.2017
diffuse across the PDB membranes, and to allow for vertical equilibration of constituents
within the PDBs.
During a second mobilization on 27 and 28 March, 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 DDW-01)
were analyzed. Field data sheets for groundwater sampling efforts are included in
Appendix A.
2.2 Surface Water Monitoring
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 2 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 2.
Surface water monitoring during the current reporting period was conducted on 27 and
28 March 2017 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
Pursuant to the sampling schedule in Monitoring Plan (presented in Table 2), water
supply wells were not sampled in March 2017. Sampling of the water supply wells that
are part of the monitoring program is scheduled to be conducted in September 2017.
2.4 Methane Monitoring
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 light poles and storm drains. Table 3 lists points that are the subject
of quarterly or annual methane monitoring. Passive structures and Site features that are
part of the methane monitoring program are depicted in Figures 3A and 3B. Monitoring
locations associated with the planned Northeast Boundary Active Wellpoint System were
not monitored during this reporting period, as this system is under construction and not
yet operational. 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 18
through 19 January and 11, 12, and 19 April 2017.
A total of nine (9) landfill gas probes were installed prior to the April landfill gas sampling
event as outlined in the Monitoring Plan. The installation was carried out by Geologic
Exploration, Inc. under the supervision of Geosyntec from 3 to 5 April 2017. The purpose
of these probes is to monitor landfill gas along the northern and western boundaries of
the Site. Four probes were installed along the northern boundary (identified as probes 44
through 47), and five probes were installed along the western boundary (identified as
probes 31 through 35).
These probes were installed to provide approximately 500 ft spacing between monitoring
points. The probe locations are shown in Figures 6 and 7. Construction logs for these
probes are included in Appendix B.
Inspection and maintenance of the three methane detection systems (located in the golf
course clubhouse, golf course maintenance building, and baseball field concession
building) was conducted by LEI Systems on 19 April 2017. These systems consist of
about 40 Macurco GD-2A detectors connected to control panels and audible alarms which

May 2017

GC5699B\2017 May York Road Report 7 05.2017
notify authorities and occupants in the event of methane detection. Additionally, stand-
alone, plug-in Macurco GD-21 methane detectors are located in the Leatherman
maintenance building, golf course chemical storage building, and baseball field ticket
booth. Two plug-in First Alert Model GCO1CN methane alarms are located inside the
John Crosland School.
Operation of the two active extraction systems (clubhouse and northeast boundary) 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 LGMP during
quarterly monitoring events in January and April 2017. 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.

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 3 March 2017 and historical groundwater
elevations are listed in Table. 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 3 March 2017 was generally consistent
with historical observations at the Site. Groundwater elevations in March 2017 were
close to historical averages recorded since 2006.
3.1.2 Groundwater Analytical Results
A summary of detected constituents and field parameters (pH, specific conductance, and
temperature) from monitoring well samples collected during the March 2017
groundwater sampling event is included in Table 5 and laboratory analytical reports are
included in Appendix C.
Low levels of some volatile organic compounds (VOCs) and metals were detected in
samples collected from Site monitoring wells in March 2017. 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 15 groundwater monitoring wells sampled,
and one metal was detected above its 2L Standard in 1 of the 15 wells sampled. Figure
5 displays a map with exceedances of the 2L Standard shown for each well. The
September 2016 analytical results reveal the following:
• 1,1-Dichloroethane was detected above its 2L Standard of 6 micrograms per liter
(µg/L) in two wells, DDW-01 at 6.1 µg/L and DDW-02 at 10.0 µg/L.
Semi-Annual Monitoring Report – First Half 2017 Former York Road Landfill, Charlotte, North Carolina
May 2017

GC5699B\2017 May York Road Report 9 05.2017
• 1,2-Dichloropropane was detected above its 2L Standard of 0.6 µg/L in three
wells, DDW-03 at 1.9 µg/L, DMW-01 at 2.2 µg/L, and DMW-06 at 2.2 µg/L.
• Benzene was detected above its 2L Standard of 1 µg/L in two wells, DDW-03A
at 1.1 µg/L, and DMW-02B at 1.1 µg/L.
• Trichloroethene (TCE) was detected above its 2L Standard of 3 µg/L in three
wells, DDW-01 at 3.8 µg/L, DDW-03 at 3.8 µg/L, and DMW-06 at 5.0 µg/L.
• Tetrachloroethene (PCE) was detected above its 2L Standard of 0.7 µg/L in three
wells, DDW-01 at 8.2 µg/L, DMW-02B at 1.1 µg/L, and DMW-06 at 1.3 µg/L.
• Vinyl chloride (VC) was detected above its 2L Standard of 0.03 µg/L in four
wells, DDW-01A at 3.4 µg/L, DDW-03 at 2.2 µg/L, DMW-01 at 2.3 µg/L, and
DMW-06 at 2.7 µg/L.
• Barium was detected above its 2L Standard of 700 µg/L in one well, DMW-02A
at 1,300 µg/L.
Historic groundwater analytical data are included in Appendix D.
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 March 2017. The Mann-Kendall test was utilized to evaluate whether or not 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:
Semi-Annual Monitoring Report – First Half 2017 Former York Road Landfill, Charlotte, North Carolina
May 2017

GC5699B\2017 May York Road Report 10 05.2017
• Thirteen (13) decreasing VOC concentration trends are considered statistically
significant at 95% confidence, compared to two (2) upward trends.
• VC at DDW-01A was found to have a statistically significant increasing trend at
a 95% confidence interval. The most recent VC concentration in this well was 3.4
µg/L, compared to the 2L standard of 0.03 µg/L.
• TCE at DDW-02B was found to have a statistically significant increasing trend at
a 95% confidence interval. The most recent TCE concentration in this well was
1.1 µg/L, compared to the 2L standard of 0.7 µg/L.
• Three (3) VOCs were found to have no statistically significant trend at a 95%
confidence interval (TCE in DDW-01, 1,4-dichlorobenzene in DMW-06, and
benzene in DMW-02B).
Decreasing concentration trends for the majority of VOCs exceeding the 2L standard
provides statistical evidence of the overall improvement to the groundwater quality for
VOCs at the Site as a result of natural attenuation processes. It is also noted that the
increasing trend of VC at DDW-01A has exhibited relatively low VC concentration
ranging from non-detect to 3.4 µg/L since 2008. Similarly, the increasing trend of TCE
at DDW-02B has exhibited relatively low TCE concentrations ranging from non-detect
to 1.5 µg/L since 2008.
The 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 results were generally consistent with historical trends. pH values were
measured within a range of 6.0 and 7.5, with the exception of DDW-01A and DMW-02A,
with pH values of 10.6 and 12.4 respectively. The pH at DDW-01A is higher than typical
readings at this well, which have historically fallen within the range of 6.6 to 7.1. 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 95.4 to
Semi-Annual Monitoring Report – First Half 2017 Former York Road Landfill, Charlotte, North Carolina
May 2017

GC5699B\2017 May York Road Report 11 05.2017
1,328 microsiemens per centimeter (µS/cm), with the exception of DMW-02A (6,800
µS/cm) which has also exhibited high specific conductance historically.
3.2 Surface Water
A summary of detected constituents and field parameters (pH, specific conductance, and
temperature) from samples collected during the March 2017 surface water sampling event
is included in Table 7, and laboratory analytical reports are included in Appendix C.
Trace levels of barium were detected in all six surface water samples, at concentrations
below its Title 15A NCAC Subchapter 2B Water Supply Standard (2B Standard) of 1,000
µg/L. No other metals, and no VOCs were detected in surface water samples during the
March 2017 sampling event.
Field parameter results were generally consistent with historical trends. pH ranged from
6.7 to 7.3 and specific conductance ranged from 101.7 to 273.0 µS/cm.
3.3 Methane
Results of methane monitoring at locations with detections above 0.1% methane from
January 2016 through April 2017 are summarized in Table 8, and landfill gas monitoring
results from January 2017 through April 2017 at monitored locations are included in
Appendix E. Table 8 and Appendix E include non-routine system performance
assessment monitoring in the northeast boundary area which is not part of regular,
quarterly monitoring. Historical landfill gas data from January 2012 through March 2017
is included in Appendix F. 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
2017) 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 lower explosive limit (LEL) of 5% along the South Tryon
Street boundary and northeast boundary during the January and April 2017 monitoring
events. At the northern boundary, probe 44 had a methane concentration of 5.0%. One
LEL exceedance was observed in an off-Site probe at Leatherman Golf during this
reporting period (6.1% methane in probe P-4 in January 2017). Since 2011, five LEL
exceedances have been observed in probes located across South Tryon Street (P-1
Semi-Annual Monitoring Report – First Half 2017 Former York Road Landfill, Charlotte, North Carolina
May 2017

GC5699B\2017 May York Road Report 12 05.2017
through P-4); three times at P-2 with a maximum methane concentration of 12.5%, and
three times at P-4 with a maximum methane concentration of 8.1%.
Although off-Site methane concentrations above the LEL were not detected along the
northeast boundary, periodically elevated concentrations of methane at select probes
indicate it is possible that off-Site migration of methane above the LEL may occur in the
subsurface along the northeast boundary. Passive monitoring points in the vicinity of the
John Crosland School (formerly the 5146 Ten Parkway Plaza Boulevard Building),
located next to the northeast boundary, were monitored on a monthly basis during the
current reporting period in response to past, occasional subsurface methane readings
above the LEL in this area. Methane concentrations were not detected in the subsurface
above the LEL in these probes during this reporting period. Methane monitoring alarms
are located within the school, as discussed in Section 3.3.3. Construction of a
supplemental landfill gas migration control system along the northeast boundary is
underway and this system is planned to be operational in 2017.
Methane was not detected above 25% of the LEL inside structures including buildings
and storm drains monitored during this period. Three LEL exceedances were observed in
the subsurface in the vicinity of light poles or scoreboards that are part of the monitoring
program during this reporting period, at BLP-10 in January and April 2017 and at SLP-
05 in January 2017. Actions taken to address these locations are described in Section
3.3.4.
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.
Semi-Annual Monitoring Report – First Half 2017 Former York Road Landfill, Charlotte, North Carolina
May 2017

GC5699B\2017 May York Road Report 13 05.2017
The clubhouse active extraction system was observed to be operating during both the
January and April 2017 landfill gas monitoring events. Methane measurements from
several points along the system that were recorded during landfill gas monitoring are
included in Appendix E.
3.3.2.2 Northeast Boundary System
The northeast boundary venting 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 active extraction system was observed to be operating during
both the January and April 2017 landfill gas monitoring events. The system was observed
not operating during a Site visit on 5 April 2017 by Geosyntec. Upon inspection, a fuse
was found to be tripped in the breaker box. After resetting the breaker, the system
returned to normal operation. An hour meter which records operating time for the blower
indicated 92.8% operating time between the October 2016 and January 2017 monitoring
events, and 99.9% operating time between the January and April 2017 monitoring events.
Figure 9 displays the valve status, applied vacuum, air flow, and methane concentration
at system vacuum extraction points as observed in April 2017. 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 of the measurements indicates the total system air flow rate was approximately
507 standard cubic feet per minute (scfm) during the April 2017 monitoring event, and
wellhead vacuum levels ranged from 1.9 to 3.1 inches of water at active wells. The
maximum methane concentration observed extraction wells was 1.5% in SU-06. The
observed flow rate is estimated to remove one trench pore volume at least every two
hours, which allows for meeting operational objectives of preventing methane from
migrating through the trench. Previous system evaluations have demonstrated that
vacuum influence is not achieved outside of the gravel-filled trench.
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 baseball field concession building)
conducted by LEI Systems on 19 April 2017 showed that these systems were functioning
properly. No alarms were reported from the plug-in methane detectors located within the
softball ticket booth, Leatherman maintenance building, golf course chemical storage
building, and the John Crosland School.
On 23 January 2017, a methane alarm was triggered in the clubhouse at around 3:00 AM.
The fire department responded to the alarm, monitored with a four-gas meter, and cleared
the alarm. On inspection, it was found that the clubhouse blower system was operating,
and the cause of the alarm was unknown.
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 2017. During January 2017 landfill cap inspections,
surficial cracks and voids were noted at 13 light poles and scoreboards and methane was
above the LEL in the subsurface at two locations, BLP-10 and SLP-05. SLP-05 is located
near the soccer fields in the southern extent of Renaissance Park and was cordoned off
with caution tape. Methane concentrations at this location were not observed to exceed
the LEL during the April 2017 monitoring event. BLP-10 is located within a locked

portion of the facility and was cordoned off with caution tape. Ambient air readings in
the vicinity of these light poles did not detect methane.
During the April 2017 landfill cap inspections, surficial cracks and voids were noted at
13 light poles and scoreboards and methane was above the LEL in the subsurface at one
location, BLP-10. This location is within a locked portion of the facility and was
cordoned off with caution tape. Ambient air readings in the vicinity of this light pole did
not detect methane.
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.
Future decommissioning of field infrastructure, such as lighting, is under discussion.
4. SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS
The following sections summarize findings and conclusions based on data collected
during the first half of 2017, and historical data collected at the Site.
4.1 Groundwater
• Groundwater elevations were generally close to elevations observed in recent
years during the March 2017 groundwater monitoring event, and were within
historical ranges.
• 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 March 2017. One or more VOCs exceeded their 2L
Standard in 8 of the 15 wells sampled. VOCs exceeding the 2L Standard in at
least one Site well were 1,1-dichloroethane, 1,2-dichloropropane,
1,4-dichlorobenzene, benzene, TCE, PCE, and VC.
• Low levels of barium were present in Site groundwater during monitoring
conducted in March 2017. Barium was detected above its 2L Standard in DMW-
02A
Semi-Annual Monitoring Report – First Half 2017 Former York Road Landfill, Charlotte, North Carolina
May 2017

GC5699B\2017 May York Road Report 16 05.2017
• A trend analysis of groundwater VOC data since 2008 indicated that decreasing
trends are present for 13 of 18 VOC constituents exceeding the 2L standard.
These trends provide evidence that natural attenuation processes are reducing
groundwater VOC concentrations at the Site.
4.2 Surface Water
Barium was detected in all six surface water samples at concentrations below its 2B
Standard. No VOCs were detected in surface water samples collected in March 2017.
4.3 Methane
• Methane was not detected above 25% of the LEL in monitored structures during
the reporting period. Methane was detected above the LEL in the subsurface in
cracks and/or voids beneath two light poles during this monitoring period. These
locations were cordoned off with cones and caution tape and are in areas that are
not accessible by the public.
• Methane concentrations at select subsurface monitoring probes exceeded the LEL
along the South Tryon Street boundary and northeast boundary. One probe near
the northern boundary had a methane concentration equal to the LEL. Methane
was not detected in probes along Sugar Creek.
• Methane concentrations in off-Site subsurface monitoring probes near the
northeast boundary were below the LEL during this reporting period.
• Methane concentrations in off-Site subsurface monitoring probes near the South
Tryon Street boundary exceeded the LEL in the subsurface at one location, P-4,
in January 2017.
4.4 Future Work
Efforts to address occasional subsurface methane migration at the northeast boundary are
ongoing. Construction of a supplemental landfill gas migration control system along the
northeast boundary is currently taking place and is planned to begin operation in 2017.
Off-Site LFG monitoring location P-4, located across South Tryon Street from the Site,
will continue to be monitored following the LEL exceedance observed in January 2017.

GC5699B\2017 May York Road Report 17 05.2017
If off-Site LEL exceedances continue, the City will evaluate measures to mitigate
methane in this area.
4.5 Recommendations
Upon implementation of groundwater sampling activities described in the newly-
approved Monitoring Plan in March 2017, it was discovered that one well, YRW-11B,
was inadvertently included in Table 4 of the plan, indicating that it would be sampled as
part of the monitoring program. This well has not been sampled regularly in the past, and
was not included in the summary of proposed Monitoring Plan changes included in the
cover letter submitted to NCDEQ with the Plan. It is not necessary to be sampled to
achieve Monitoring Plan objectives. It is proposed that YRW-11B be removed from the
groundwater sampling plan going forward, for consistency with the intent of the
Monitoring Plan.
