1. INTRODUCTION
On behalf of the City of Charlotte, Geosyntec Consultants of NC, PC (Geosyntec) has
prepared this Semi -Annual Monitoring Report, Second Half 2019 for the City of
Charlotte's former York Road Landfill. This report presents the results through
November 2019 of groundwater, surface water, and methane monitoring conducted at the
former landfill since the previous Semi -Annual Monitoring Report (Geosyntec, 2019)
was submitted in May 2019.
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 hiking, biking, and disc golf.
In July 2016, the soccer and softball athletic fields at Renaissance Park were closed to the
public to alleviate continuous field maintenance efforts and potential safety issues caused
by effects of the former landfill. 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 completed by September 2019 and portions of the park where demolition occurred
have since been utilized as passive park spaces (e.g. open fields and dog park areas).
Other Site facilities outside of the demolition area including the golf course, bike trails,
and disc golf courses remain in operation.

1.2 Hydmeologic Settin
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 IOG, 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

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 30 August through 20 September 2019 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 30 August 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 30 August 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.

Former York Road Landfill, Charlotte, North Carolina consultants
November 2019
Geosyntec Consultants of NC, PC
During a second mobilization on 20 September 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 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 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 20
September 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. No sample was collected from location NT-2 as the
location was dry. 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 the Monitoring Plan (presented in Table 3), annual
sampling of water supply wells WSW-2 and WSW-3 was carried out on 20 September
2019. These wells are located adjacent to 6431 and 6505 South Tryon Street,
respectively. These samples were collected from exterior spigots on the side of each
residence.
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 1 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 23 through 26 July and 30 September through
2 October 2019.
On 2 October 2019, the trench system blower at the northeast boundary was temporarily
shut off as part of a trial effort to assess the potential for landfill gas mitigation without
the operation of the trench blower system (while the wellpoint northeast boundary
methane control system continued operation). Additional methane monitoring events
were conducted at nine (9) sampling locations in a transect across the northeast boundary
on 4 October, 18 October, and 1 November 2019 following the temporary shutdown of
the older (trench) blower system located at the northeast boundary of the Site. Methane
measurements from the transect monitoring events during the reporting period are
provided in Section 3 of this report.
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 July and October 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 30 August 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 30 August 2019 was generally consistent
with historical observations at the Site.
Water level measurements from fourteen (14) of the twenty-one (21) well locations were
slightly above or below historical water level averages at respective well locations during
the August 2019 gauging event. Water levels at DMW-A, DMW-08, and DMW-02A
were approximately 1.0 to 37.6 ft above historical averages. The water level at DMW-
02B was about 7.2 ft below the water level historical average at this location. T he average
water table elevation at DMW-02A between March 2006 and March 2018 was
approximately 553 ft above mean sea level, but measurements from September 2018,
March 2019, and September 2019 at DMW-02A have been significantly higher than the
historical average. The anomalous measurements at DMW-02A and DMW-02B may
have been caused by potentially damaged well casings or other issues related to well
integrity. Since water level data at DMW-02A is generally not representative of static
conditions, it was 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
September 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 September 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 16 groundwater monitoring wells sampled,
and one or more metals were detected above their 2L Standards in 9 of the 14 wells
sampled for metals analyses. No VOCs were detected in water supply well samples
collected during the September 2019 monitoring event. Figure 5 displays a map with
exceedances of the 2L Standards shown for each well. The September 2019 analytical
results reveal the following:
• 1, 1 -Dichloroethane was detected above its 2L Standard of 6 micrograms per liter
(µg/L) in three wells: DDW-01A at 6.1 µg/L, DDW-02 at 9.8 µg/L, and DDW-
01 at 7.5 µg/L.

wells: DMW-01 at 1.3 µg/L, DDW-03 at 2.0 µg/L and DMW-06 at 2.3 µg/L.
• 1,4-Dichlorobenzene was detected above its 2L Standard of 6 µg/L in one well:
DMW-06 at 6.6 µg/L.
• Benzene was detected above its 2L Standard of 1 µg/L in five wells: DMW-01 at
14.3 µg/L, DDW-01A at 4.6 µg/L, DDW-03 at 1.5 µg/L, DDW-03A at 3.6 µg/L,
and DMW-02B at 1.7 µg/L.
• Trichloroethene (TCE) was detected above its 2L Standard of 3 µg/L in four wells:
DDW-0IA at 5.9 µg/L, DDW-03 at 3.1 µg/L, DDW-01 at 6.4 µg/L, and DMW-06
at 5.1 µg/L.
• Tetrachloroethene (PCE) was detected above its 2L Standard of 0.7 µg/L in two
wells: DDW-01A at 1.0 µg/L and DDW-01 at 4.9 µg/L.
• Vinyl chloride was detected above its 2L Standard of 0.03 µg/L in five wells:

2,840 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 September 2019, and where less than half of data points in the data set were non -detect.
The 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:

Fourteen (14) decreasing VOC concentration trends are considered statistically
significant at 95% confidence: PCE at DDW-01, benzene at DMW-01, TCE at
DDWO1-A, DDW-03, and DMW-06; vinyl chloride at DDW-03, DMW-01, and
DMW-06; 1,1-dichloroethane at DDW-01 and DDW-02; 1,2-dichloroethane at
DMW-06, and1,2-dichloropropane at DMW-01 and DDW-03 and DMW-06.
• Four (4) increasing VOC concentration trends are considered statistically
significant at 95% confidence: TCE at DDW-01, vinyl chloride at DDW-01A; and
benzene at DDW-03 and DMW-02B.
• Two (2) VOC concentration trends were found to have no statistical significance
at a 95% confidence interval: 1,1-dichloroethane at DDW-01A and 1,4-
dichlorobenzene at DMW-06.
Mann -Kendall trend analyses were conducted for seven (7) VOC compounds across
seven (7) of the Site well locations (DDW-01, DDW-01A, DDW-02, DDW-03, DMW-
01, DMW-0213, and DMW-06). Trend analyses were not conducted for compounds at
these locations where concentrations were above the 2L Standard in September 2019 and
more than half of data points in the historical data series were non -detect: vinyl chloride
at DDW-01, benzene and PCE at DDW-01A; and 1,2-dichloroethane and 1,2-
dichoropropane at DDW-03. 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 six (6) 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 compound and one metal compound decreased to below the 2L Standard at
wells which had an exceedance in April 2019. A decrease in PCE concentration was
observed at DMW-06 in September 2019 (not detected) compared to the April 2019
concentration (1.1 µg/L) at this location. Mercury concentrations increased to above the
2L Standard at DDW-02 from September 2017 to April 2019 but were not detected here
in September 2019.
Eight VOC compounds increased above the 2L Standard since the April 2019 sampling
event: vinyl chloride and 1,1-dichloroethane at DDW-01; 1,1-dichlorethane at DDW-
01A; 1,2-dichloroethane and TCE at DDW-03; benzene and 1,2-dichloropropane at
DMW-01; and 1,4-dichlorobenzene at DMW-06. With the exception of iron at DMW-

08, no metal compounds increased above respective 21, Standards since the April 2019
or September 2018 (iron and manganese only) sampling events.
Iron and manganese have been analyzed annually in samples from eight well locations
(DDW-01, DMW-01, DMW-02, DMW-05, DMW-06, DMW-08, DMW-A, and YRW-
IOC) since September 2016 and were considered in the September 2019 sampling effort.
These metals have regularly occurred above the respective 2L Standards (300 µg/L for
iron and 50 µg/L for manganese) at each of these wells since March 2008. Historically,
DDW-01 has had the fewest occurrences of iron and manganese concentrations above the
2L Standards. Occurrences of these metals below the 21, Standards have been regularly
observed at DMW-08 since September 2016, but iron concentrations above the 2L
Standard were noted in September 2017 and September 2019. At DMW-06, iron has
been reported below the 2L Standard since September 2014 but manganese has never
been observed below the 2L Standard.
1, 1 -dichloroethane was detected above the 2L Standard at DDW-01 for the first time since
March 2017, though concentrations were previously just below the 2L Standard of 6 µg/L
with the exception of September 2018. Vinyl chloride was detected above the 2L
Standard but below the reporting limit at this well for the first time on record.
Concentrations of 1,1-dichoroethane have fluctuated at DDW-01A and have remained
below the 2L Standard since March 2014 until September 2019 (6.1 µg/L). At DMW-01
the concentration of 1,2-dichloropropane was detected for the first time since September
2017 with a concentration above the 2L Standard. TCE and 1,2-dichloroethane were
above the 2L Standard at DDW-03 in September 2019. The TCE concentration at this
location (3.1 µg/L) was consistent compared to historical concentrations, but the
September 2019 1,2-dichloroethane observation (1.1 µg/L,) marked the first occurrence
of the compound at DDW-03 since September 2014. The concentration of 1,4-
dichlorobenzene at DMW-06 (6.6 µg/L in the duplicate sample) was greater than the 2L
Standard in September 2019 and marked the highest concentration of this compound seen
at this location since April 2009 (6.5 µg/L). PCE has consistently occurred above the 2L
Standard at DMW-06 with the exception of March 2018 and September 2019, when the
compound was not detected.
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 5.7 to 8.0, with the exception of DMW-02A,
which had 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 73 to 1,625 microsiemens per centimeter (µS/cm),
with the exception of DMW-02A (6,701 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 September 2019 surface water sampling
event is included in Table 7, and laboratory analytical reports are included in Appendix
B.
Surface water samples were collected from five locations (NT-1, SC-1, SC-2, ST-1, and
ST-3) in September 2019 (Figure 2). Dry stream conditions prevented sampling at NT-
2 during the sampling effort. Barium was the only compound detected at sampled
locations during the current reporting period and barium concentrations ranged from 25.6
µg/L (SC-1) to 78.5 µg/L (ST-1) all below its Title 15A NCAC Subchapter 2B Water
Supply Standard (2B Standard) of 1,000 jig/L. These concentrations are consistent with
previously reported barium concentrations at these locations, which have been reported
at all surface water sampling locations since March 2008. No surface water samples were
collected at NT-2 during the September 2019 sampling event due to dry stream
conditions, which were also observed in September 2017 and September 2018. No VOCs
were detected in surface water samples during the September 2019 sampling event.
Chromium was reported in samples from SC-1 and SC-2 at above the NC 2B standard
(2.6 µg/L) in April 2019; however, no chromium was detected at these locations in
September 2019.
Field parameter results were generally consistent with historical ranges at each of the
surface water sampling locations. pH ranged from 7.1 to 7.8 and specific conductance
ranged from 189 µS/cm (NT-1) to 584 µS/cm (ST-1). The specific conductivity value at

ST-1 in September 2019 was greater than the historical average (approximately 280
µS/cm), however, within historical ranges for this location.
3.3 Methane
Results of methane monitoring at locations with detections above 0.1 % methane from
January 2018 through October 2019 are summarized in Table 8, and landfill gas
monitoring results from July 2019 through November 2019 at monitored locations are
included in Appendix D. Historical landfill gas data from January 2012 through
November 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 quarterly monitoring
event (October 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 northern
boundary, northeast boundary, the South Tryon Street boundary, and at one monitoring
probe (P-4) at the Leatherman Golf maintenance shop during the July and October 2019
monitoring events. The methane concentrations at the Leatherman Golf maintenance
shop, which were higher than historical concentrations, may be attributed to the recent
replacement of the surficial gravel at the maintenance shop parking lot with asphalt.
Methane was not detected in probes along Sugar Creek on the western boundary. With
the exception of the Leatherman Golf maintenance shop probe (P-4), no LEL exceedances
were observed in off -Site probes during this reporting period.
Historically, LEL exceedances have been observed in multiple probes located across
South Tryon Street (P-1 through P-4) since 2011. Notably, the July and October 2019
concentrations of methane at P-4 were 6.8% and 9.8%, respectively, whereas the prior
two measurements in this probe (January 2019 and October 2018) were 0.0%.
Methane was detected at above the LEL at multiple on -site locations at the northern
boundary (41 through 44) in January and April 2019; however, methane only occurred
below the LEL (0.7 to 1.6%) and at only two of these locations (42 and 43) during the
July and October 2019 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;
GC5699D\CAR190032 14 11.2019

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 occurred historically 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 methane detections were observed near the northeast
boundary during the reporting period, which suggests the active extraction systems are
working effectively. Also, to evaluate the potential that the older trench system is not
necessary to provide methane migration across the property boundary, on 2 October 2019,
the trench system blower at the northeast boundary was shut off as part of a trial effort to
assess the potential for landfill gas mitigation without the operation of the trench blower
system (while the wellpoint landfill gas migration system continued to operate).
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.
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.Z1 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
GC5699D\CAR190032 15 11.2019

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 July
and October 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.
Several non -critical low vacuum alarms occurred at the clubhouse venting system during
this reporting period. The tubing connection to the vacuum gage was replaced by
Geosyntec in August 2019 due to water in the line causing the alarm to trip.
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
GC5699D\CAR190032 16 11.2019

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 23 July and 2 October 2019 landfill gas monitoring events and ran approximately
100% of the time between the 23 July 2019 and 2 October 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 (October 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 September 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 of the measurements indicates the total system air flow rate was approximately
526 standard cubic feet per minute (scfm) during the September -October 2019 monitoring
event. Wellhead vacuum levels ranged from 11.6 to 52.9 inches of water at active wells,
and methane was not detected at the extraction wells in October 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. On 2 October 2019, the trench system blower at the northeast
boundary was temporarily shut off as part of a trial effort to assess landfill gas mitigation
without the operation of the trench blower system (while the wellpoint landfill gas
migration system continued to operate).
Four weekly to bi-weekly sampling efforts were conducted at nine (9) S-7 transect
monitoring probes between 4 October and 1 November 2019 (Table 10). Methane was
observed at PC-13 on 4 October 2019 at a concentration of 0.4% but was not observed
here during subsequent sampling events. Methane was recorded at 0.9% at S-7 on 4
October 2019 but was observed at 0.1 % during the following sampling events on 11
October and 18 October 2019. Methane was not measured at S-7 on 1 November 2019
since the probe was not accessible at the time of sampling due to a locked gate. Methane
was instead measured at S-7 on 22 November 2019 and was not detected. The trench
system blower remains off as of November 2019 and if continued monitoring suggests

that methane gas migration is successfully controlled without the operation of the trench
collection system, Geosyntec may recommend that the operation of this system be
permanently discontinued. The next anticipated S-7 transect sampling event will be in
December 2019.
3.3.Z3 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 July and October 2019 landfill gas monitoring events and ran
approximately 100% of the time between the July 2019 and October 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 October 2019. Figure 11 displays the applied well vacuum and flow at each
point, along with the methane and carbon dioxide concentrations observed on 1 October
and 2 October 2019. The sum of PC well flow measurements indicates the total system
air flow rate was approximately 526 scfm during the October 2019 monitoring event, and
wellhead vacuum levels ranged from 11.6 (PC-23) to 52.9 (PC-13) inches of water at
active wells. Flow rates ranged from 5.9 scfin (at PC-7) to 44.4 scfm (PC-18) within the
PC well system in October 2019. Methane concentrations in the PC wells ranged from
0.0% (at several wells) to 30.4% (PC-15). Gas measurements were not obtained at PC-4
in July or October 2019 due to a fallen tree covering the probe location.

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. 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.
Five non -critical (not methane) alarms were observed at methane detection systems in the
softball field concession stand (1 alarm due to a wire circuit), golf course clubhouse (1
alarm due to cellular system), and the golf course maintenance building (3 alarms due to
telephone and power outages) during this reporting period. All alarm incidents during
the reporting period were followed by same day methane system inspections by
Geosyntec personnel and the detection systems were reported as functioning during each
of the on -site alarm investigations.
3.3.4 Landfill Cap Inspection and Repairs
Visual inspections of the landfill cap were completed by Geosyntec during quarterly
monitoring in July and October 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. During the
July 2019 and October 2019 landfill cap inspections, holes larger than a foot wide were
noted at seven (7) storm drain locations. These storm drain locations include SD-11, SD-
25, SD-26, SD-40, SD-41, SD-42, and SD-43 and are anticipated to be repaired with
flowable fill.

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
• Water level measurements from fourteen (14) well locations were an average of
0.5 ft lower than respective average historical water levels at the Site on 30 August
2019. Higher than average water levels were observed in the remaining seven (7)
wells and were 0.9 ft higher (on average) compared to respective average
historical water levels at these locations. 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 September 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-dichloroethane, 1,2-
dichloropropane, 1,4-dichlorobenzene, benzene, TCE, PCE, and vinyl chloride.
• VOCs were not detected in the two water supply wells sampled.
• Low levels of metals were present in Site groundwater during monitoring
conducted in September 2019. One or more metals were detected above their 2L
Standard in 9 of the 14 wells sampled. Metals exceeding the 2L Standard in at
least one Site well were barium, cadmium, iron, and manganese.
• A trend analysis of groundwater VOC data since 2008 indicated that decreasing
trends are present for 14 of 20 VOC constituents analyzed. These trends provide
evidence that natural attenuation processes are reducing groundwater VOC
concentrations at the Site.
• One VOC compound (PCE at DMW-06) and one metal compound (mercury at
DDW-02decreased to below the 2L Standard at wells which had an exceedance
in April 2019. Eight VOC compounds increased above the 2L standard since the

April 2019 sampling event: vinyl chloride, and 1,1-dichloroethane at DDW-01;
1,1-dichlorethane at DDW-01A; 1,2-dichloroethane and TCE at DDW-03;
benzene and 1,2-dichloropropane at DMW-01; and 1,4-dichlorobenzene at
DMW-06. With the exception of iron at DMW-08, no metal compounds increased
above respective 2L standards since the April 2019 or September 2018 (iron and
manganese only) sampling events.
4.2 Surface Water
Barium was detected at the five sampled surface water locations at concentrations below
the 2B Standard. Chromium, which was detected at SC-1 and SC-2 in April 2019, was
not detected. No VOCs were detected in surface water samples collected in September
2019. Surface water sampling location NT-2 was dry, therefore no sample was collected.
4.3 Methane
• Two (2) methane concentrations in off -Site subsurface monitoring probes near the
northeast boundary and South Tryon Street boundary exceeded the LEL during
the monitoring period between April 2019 and November 2019. Both
exceedances occurred in P-4 at the Leatherman Golf Maintenance Shop.
• 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.
• To evaluate the potential that the older trench system is not necessary to provide
methane migration across the property boundary, on 2 October 2019, the trench
system blower at the northeast boundary was shut off as part of a trial effort to
assess the potential for landfill gas mitigation without the operation of the trench
blower system (while the wellpoint landfill gas migration system continued to
operate). The trench system blower remains off as of November 2019 and if
continued monitoring suggests that methane gas migration is successfully

controlled without the operation of the trench collection system, Geosyntec may
recommend that the operation of this system be permanently discontinued in a
future monitoring report. The next anticipated S-7 transect sampling event will
be in December 2019.
4.4 Additional Activities
The following additional activities took place during this reporting period:
• Routine maintenance at the northeast boundary blower system, including oil
changes and belt replacement.
• Wellhead at P-4 was repaired after being covered by asphalt.
4.5 Future Work
• Continued landfill gas monitoring following the shutdown of the trench collection
system at the northeastern boundary of the Site. The next anticipated monitoring
event will occur at select probes in December 2019. The trench system blower
remains off as of November 2019 and if continued monitoring suggests that
methane gas migration is successfully controlled without the operation of the
trench collection system, Geosyntec may recommend that the operation of this
system be permanently discontinued in a future monitoring report.
• Quarterly landfill gas monitoring will continue, as described in the monitoring
plan. Off -Site LFG monitoring location P-4, located across South Tryon Street
from the Site, will continue to be monitored following the LEL exceedances
observed in July and October 2019.
• Seven (7) holes next to storm drains will be repaired with flowable fill.
