1.0 INTRODUCTION
This Design Hydrogeologic Report (DHR) is prepared to support the Permit to Construct for Phase 4
of the Charlotte Motor Speedway (CMS) Landfill V in accordance with North Carolina Administrative
Code Title 15A Chapter 13B Subchapter .1623. The Landfill is constructed and operated in phases
per the Landfill's approved Facility Plan with Phase 4 being the next phase to be constructed. As
specified in the rule, the scope and purpose of this DHR is to:
• Provide adequate information to demonstrate compliance with the vertical separation
and foundation standards set forth in the rule.
• Provide an investigation of the hydrogeologic characteristics of the upper -most aquifer
for the proposed phase of landfill development. The purpose of this investigation is to
provide more detailed and localized data on the hydrogeologic regime for this area in
order to design an effective water quality monitoring system.
The following sections present descriptions of the physical, geologic and hydrogeologic settings for
the proposed Phase 4 landfill and a history of previous investigations relevant to this DHR. The Solid
Waste Section previously authorized utilizing data from previous investigations prepared for the CMS
Landfill V to provide a characterization of the hydrogeology beneath Phase 4. A description of these
previous investigations is in Section 1.4.
1.1 PHYSICAL SETTING
The Charlotte Motor Speedway Landfill V is an active municipal solid waste management facility
operating under the State solid waste permit 1304-MSWLF-1992. BFI Waste Systems of North
America, Inc. a wholly owned subsidiary of Republic Services, Inc. owns and operates the Landfill.
The Landfill's physical address is 5105 Morehead Road in Concord, North Carolina and is located on
a combined 697.7-acre property. Figure 1 illustrates the location of the Landfill property on a United
States Geological Survey 7.5-minute topographic quadrangle map.
The Landfill is segmented into phases, with Phase 1 - 3 already constructed and operational or
permitted to construct and Phase 4 is the next phase to construct. The proposed Phase 4 is roughly
7.78 acres in size. An existing groundwater and methane gas monitoring well network encompass
all Phases of the Landfill as shown on Figures 2 and 3.
1.2 GEOLOGIC SETTING
This section presents a summary of the regional and local geology for the CMS Landfill V. The Landfill
is located within the Charlotte Belt of Piedmont physiographic and geologic province. The Charlotte
Belt is characterized by intrusive felsic and mafic bodies with varying degrees of metamorphism. The
Landfill is more specifically located within the Concord Pluton of the Charlotte Belt and is comprised
of diorite (Ordovician to Devonian) with a mineral composition of cumulus olivine, clinopyroxene, and
plagioclase and syenite (Silurian) with a mineral composition of orthoclase feldspar, augite,
hornblende, biotite, and a coarse porphyritic texture with megacrysts of pink feldspar.
Saprolitic overburden (aka saprolite) is the dominant upper -most geologic unit present at the
Landfill. At most locations throughout the Landfill property, the saprolite transitionally grades from
sediment material in which the relict metamorphic and igneous structures can be identified to the
parent bedrock from which it is derived. The transition zone where finer sediment materials grade
CMS LF V Phase 4 www.scsenaineers.com
Design Hydrogeologic Report 5

into more pebble and cobble sized fragments has been designated the partially weathered rock
(PWR) unit.
Saprolite is present at most locations across the Landfill property. The residuum associated with the
saprolite generally consists of clay and silt underlain by micaceous sandy silts and silty sands. In
addition, alluvium and colluvium were observed as the upper -most geologic unit near smaller surface
drainage features and the Rocky River. The alluvium is of limited thickness and overlays saprolite or
bedrock. The alluvium ranges in grain size from clayey silt to poorly sorted sands.
The saprolite consists primarily of red -brown or light to dark brown, fine micaceous sandy silt with
clay with some areas of silty clay or silty sand. The saprolite generally grades to silty sand with rock
fragments with depth. White, gray, brown, and black colors are present and correlate with the diorite,
syenite, or diabase bedrock from which the soils were derived. Thin zones of red -brown, orange, or
tan lean clays are also present in zones of differential weathering.
Hard rock fragments and partially weathered rock (PWR) are present in this lower portion of the
saprolite, which become larger and more frequent with depth. The contact with the underlying PWR
or bedrock is gradational. The depth at which drilling refusal with hollow -stem augers was
encountered defines the base of the saprolitic overburden.
Deeply weathered bedrock material consisting of white, gray, dark grey, brown, or yellow silty sand
with some intervals of sandy silt characterize the PWR. In addition, hard, but weathered, rock
fragments are also present within the PWR. Local areas grey/black and green/gray materials derived
from predominately-mafic parent rocks were also observed in the PWR unit.
Diorite with diabase intrusions dominate the bedrock type underlying the Landfill. The contact with
the syenite ring dike that encompasses the diorite unit is located just beyond the western boundary
of the Landfill. Syenite was reported in isolated surface exposures near the northwest portion of the
Landfill near banks of the Rocky River and in a few nearby cores within this relatively small area of
the site. These occurrences are expected, as the contact between these bodies is gradational and
typically not uniform on a local scale. Two small, northwest trending diabase dikes occur in this same
portion of the site and previous investigations in portions of Phase 3 identified small east -west
trending diabase dikes. The occurrence of the intrusions suggest a relationship between these
intrusive rock units, the local joint patterns, and the flow path of the Rocky River and tributaries. The
diorite is generally light gray and black in color, and generally comprises 90 percent of the rock
mass. The remaining rock mass is comprised of the isolated syenite identified and, to a lesser
extent, diabase intrusions. The syenite will appear similar to granite with black, gray, and brown fine
to coarse -grained crystals in a white matrix and the diabase will generally be dark green/gray in
appearance with fine to medium -grained crystals of similar color.
Bedrock outcrops at the Landfill near the banks of Rocky River and tributaries were reported in
previous investigations. No other bedrock outcrops at the Landfill have been observed. A fracture
trace analysis was performed and reported in the Phase 2 (Cells F-H) DHR and Site Suitability
Update. A map of the reported fracture trace analysis is provided in Appendix A. The dominant
fracturing directions at the Landfill are from N25E to N35E / S25W to S35W. Secondary sets of
fracturing are from N75E to N70E / N75W to N70W. Fracture directions appear uniform and
correlate to the flow path of the Rocky River and tributaries. No seismic activity were identified in this
or any of the previous investigations.

1.3 HYDROGEOLOGIC SETTING
This section presents a summary of the regional and local hydrogeology for Phase 4 and the overall
Landfill. Groundwater in the Piedmont physiographic and geologic province occurs as unconfined
aquifers in the saprolite, PWR, and fractured bedrock. These zones are interconnected through open
fractures and pore spaces. The surface of the upper -most aquifer typically correlates to the local
topography.
The infiltration of precipitation recharges the upper -most aquifer. The recharge rate is primarily
affected by rainfall intensity and duration, pre-existing soil moisture conditions, temperature
(evaporation), and plant uptake (transpiration). Most of the property is comprised of the active
landfill and support infrastructure and flood plain areas associated with Rocky River.
Seasonal high-water tables are typically observed during the spring to early summer months of the
year when maximum infiltration efficiency occurs due to lower temperatures and less plant uptake
(less evapotranspiration). In addition, as snow and ice melt from the higher elevation during the
spring months, the receiving rivers and streams will exhibit additional surge from the increased
runoff volume and will influence groundwater elevations in nearby areas. Seasonal low-water tables
are typically observed during the fall months when minimum infiltration efficiency occurs due to
higher temperatures and greater plant uptake of water (more evapotranspiration).
Precipitation that infiltrates into the ground will seep downward following the path of least resistance
through zones of relatively higher conductivity in the saprolite and PWR. Upon contact with a less
permeable surface (i.e. competent bedrock or clay confining layer), the water will spread laterally
until it finds another relatively higher conductive pathway downward such as a weathered zone or a
fracture, or until it is discharged to the surface water system. These discharges are generally
intermittent, and generally occur in the secondary drainage features following precipitation events.
1.4 INVESTIGATION HISTORY
The following subsections summarize the previous investigations as documented and presented in
the Landfill's Initial Phase 1 Site Investigation, Phase 2 Cells 2A-2E DHR, Phase 2 Cells 2F-2H DHR,
and Phase 3 DHR (Cells 21, 2J, 2K & 2M). Data and information in these previous documents is
presented in this report only to the extent necessary to support the Phase 4 expansion.
1.4.1 Initial Phase 1 Site Investigation
On November 30, 1987, the City of Concord approved the re -zoning of the un-developed property to
allow construction of a sanitary landfill. Westinghouse Environmental and Geotechnical Services,
Inc. (Westinghouse) initially investigated the property on behalf of Browning -Ferris Industries (BFI at
the time) in 1988 as part of the site suitability study in support of the Site Plan Application. The
investigation consisted of installation of test borings and observation and monitoring wells with rock
coring performed at select locations to assess the suitability of the property for permitting and
construction of a sanitary landfill.
The North Carolina Department of Environment, Health, and Natural Resources (NCDEHNR) Solid
Waste Section (SWS) issued a Permit to Construct (PTC), Permit No. 13-04, for the Landfill on April 1,
1991, followed by minor permit amendments during the same year. The SWS approved the Permit to
Operate (PTO) for Phase 1 Cell 1A and amendments to the PTC on March 6, 1992.

1.4.2 Phase 2 Cells A-E DHR
S&ME submitted a DHR for Phase 2 Cells 2A, 213, 2C, 2D, and 2E in February 1994 and subsequent
revisions through 1995. 91 auger borings, 50 groundwater observation wells, and eight rock cores
completed for the DHR investigation. Standard Penetration Tests (SPTs) were performed at select
locations and at designated intervals during installation of the observation wells with collection of
bulk and undisturbed samples for geotechnical testing and analyses. Installed observation wells
slug testing for in -situ permeability was completed for calculating hydraulic conductivity.
Changes to the Water Quality Monitoring Plan included conversion of select observation wells to
permanent monitoring wells and the addition of two monitoring wells installed during cell
construction. On April 25, 1995, a PTO amendment was completed and a PTC was issued for Phase
2 Cells 2A-2E.
1.4.3 Phase 2 Cells F-H DHR
ENSR Consulting and Engineering (NC), Inc. submitted a DHR for Phase 2 Cells 2F, 2G, and 2H in
2003 with subsequent revisions through 2005. 129 test borings at 119 locations were performed as
part of the DHR investigation. 99 of the borings were converted to groundwater observation wells,
nine of which were deep wells screened in bedrock. Rock coring was performed at 16 boring
locations. Standard Penetration Tests (SPTs) were performed at 54 boring locations at designated
intervals during installation of the observation wells with collection of bulk and undisturbed samples
for geotechnical testing and analyses. For 42 of the installed observation wells, slug testing for in -
situ permeability was completed for calculating hydraulic conductivity.
Changes to the Water Quality Monitoring Plan included conversion of five installed groundwater
observation wells to permanent monitoring wells with the addition of four monitoring wells installed
during cell construction. In addition, a receptor survey was updated and did not identify any existing
or potential receptors in the area. On July 14, 2006, an amendment was made to the PTC for
construction of Phase 2 Cells 2F-2H.
1.4.4 Phase 3 Cells I, J, K, and M DHR
David Garrett and Associates submitted a DHR for Phase 3 Cells 21, 2J, 2K, and 2M in 2008 and a
subsequent revision in 2009. 85 test borings were completed at 78 different locations with
numerous test pits completed as part of the DHR investigation. Most of the borings were converted
to groundwater observation wells with eight shallow and deep nested pairs. Rock coring was
performed at 13 of the boring locations. Standard Penetration Tests (SPTs) were performed at select
locations at designated intervals during installation of the observation wells with collection of bulk
and undisturbed samples for geotechnical testing and analyses. For 26 of the installed observation
wells, slug testing for in -situ permeability was completed for calculating hydraulic conductivity.
Changes to the Water Quality Monitoring Plan included relocation of two monitoring wells and the
addition of nine monitoring wells installed during cell construction. On April 12, 2010, an
amendment was made to the PTC for construction of the Phase 3 landfill expansion.

2.0 PHASE 4 LANDFILL INVESTIGATION ACTIVITIES
The proposed Phase 4 landfill expansion area is located adjacent to the existing Phase 2 Cells 2C,
2D, 2E, and 2F, to the south and west of the referenced cells. The area for the proposed Phase 4 is
roughly 7.78 acres in size and the investigative area is 19.59 acres. As described in the following
subsections, this investigation includes previous site investigations borehole drilling, groundwater
observation wells (aka piezometer) installation and surveying, groundwater level measurements, and
aquifer testing.
2.1 BOREHOLE DRILLING
To characterize the subsurface beneath and around the proposed Phase 4 landfill expansion area,
boring logs from the previously completed investigations were used. At a minimum, the area of
investigation was the area within the proposed waste unit footprint and waste unit compliance
boundary.
Borehole drillings were performed by North Carolina licensed drillers. Methods for advancing
boreholes to target depths included hollow stem auger (HSA) and air rotary. A description of each
drilling method utilized in the previous investigations are provided below.
HSA drilling was conducted at designated locations to obtain lithologic information. Each
HSA boring was advanced to the top of the bedrock (aka point of auger refusal) using
various drill rigs and various outer diameter HSAs. Lithologic information was obtained
through split spoon sampling at 2-foot intervals as outlined in ASTM Method D-1586 or
logged from drill cuttings. During the driving of the split spoon sampler, blow counts were
recorded and the sample was examined by the field technician and described for color,
grain size, Unified Soil Classification System (USCS) code, and texture. The depth of the
partially weather rock (PWR) stratum was noted where observed. The depth to top of
bedrock was defined as the depth to auger refusal. Geotechnical samples collected
during HSA drilling included grab, bulk, and undisturbed Shelby tubes samples.
Geotechnical samples were collected and analyzed as described in Section 2.3.
• Air rotary drilling was utilized to advance boreholes in bedrock to provide adequate
annular space for well installation. The air rotary boreholes were drilled for the purposes
of permanent groundwater monitoring well and piezometer installations in bedrock. Drill
cuttings were logged continuously to identify rock type. Grain size of the cuttings was
observed to characterize properties and quality of the rock being drilled.
Various geologic, construction, and boring log recorded data for installed groundwater observation
wells (aka piezometers) and groundwater monitoring wells previously and currently located within the
Phase 2 and Phase 3 investigation areas provided in Appendix B. The following selected lithologic
observations are extrapolated from the data:
• The overburden observed during drilling included alluvium and saprolite.
Across the Phase 2 and 3 landfill areas, saprolite is observed to range in thickness from
2 feet to greater than 20 feet. Saprolite observed to be thicker beneath hills and ridges
compared to side slopes or drainage areas. The saprolitic soils have been observed to be
dry to saturated where encountered.
CMS LF V Phase 4 www.scsenaineers.com
Design Hydrogeologic Report 9

• PWR thickness across the Landfill property ranges from absent where alluvium or
saprolite directly overlies bedrock to more than 20 feet. Within the proposed expansion
area for the Phase 4 landfill, the average PWR thickness estimated at 0 to 5 feet.
• PWR is observed to be dry to saturated at most boring locations. Saturated conditions
observed in the PWR at two locations within the Phase 4 area.
Bedrock is anticipated to be largely diorite within the Phase 4 area. Bedrock fracture
zones observed in the historical boring logs. Fracture zones can be identified by the
sudden drop of the drill rod or drastic change in drilling conditions, often paired with a
simultaneous pause in the chatter from the air rotary bit. When a substantial fracture
was encountered that produced water or a drastic increase in water production, this was
interpreted to indicate the presence a water -bearing fracture. This depth was targeted
for well screen placement in bedrock.
Stratigraphic cross -sections were created identifying the hydrogeologic and lithologic units and
stabilized water table. These cross -sections are based on the historical lithological information and
static groundwater elevations from the Phase 2 DHR investigation borings and routine monitoring of
the groundwater wells at the Landfill. The cross -sections included as Figures 4 - 8 and a cross-
section transect map provided as Figure 9.
2.2 ROCK CORING
Rock coring was performed during previous DHR investigations utilizing a wire line double -tube core
barrel retrieval methodology. A double tube core barrel was attached to the bottom of the drill rods
and lowered to the bottom of the borehole and top of formation. The desired coring interval was
drilled using a toothed core bit and potable water circulated inside the boring from the bottom of the
core barrel to ground surface to displace drill cuttings. When the desired depth was reached or
drilling conditions dictated as such, the core barrel and drill rods were retrieved from the borehole.
The core sample was then extruded and placed into a box labeled with the core ID and depth
intervals.
The percent recovery, rock quality designation (RQD), orientation and frequency of likely fractures,
joints angles, observed fracture infilling or coatings, gross mineralogy, and other notable
characteristics were recorded during rock coring activities. The RQD was determined by dividing the
total length of rock fragment longer than four inches over the total length cored.
Core recoveries, RQD values, and lithologic descriptions for rock coring performed during previous
investigations at the Landfill are provided in Table 1.
Observations from the rock cores collected during previous investigations generally show a moderate
to highly fractured top of bedrock that becomes more competent with depth. Recovery values range
from zero to 100 percent and RQD values ranged from zero to 100 percent. These percentages
indicate that the bedrock is differentially weathered and variably fractured. Recovery and RQD values
generally increase with depth indicating less fracture density at greater depths.
2.3 GEOTECHNICAL ANALYSIS
Bulk and undisturbed soil samples were collected and laboratory tested during previous DHR
investigations using the following methods:
CMS LF V Phase 4 www.scsenaineers.com
Design Hydrogeologic Report 10

• Standard Proctor (ASTM D 698);
• Particle size analysis (ASTM D 422);
• Soil classification: Unified Soil Classification System (USCS) (ASTM D 2487);
• Atterberg limits (ASTM D 4318);
• Natural moisture content (ASTM D 2216); and
• Undisturbed and remolded hydraulic conductivity (ASTM D 5084).
Tabulated geotechnical field and laboratory data from previous Phase 2 and 3 DHR investigations
provided in Appendix C and D and discussed further below.
• Particle size distribution mostly silts and sands with less clay and gravels present with
USCS classifications ML, CL, CH, SM, and SC.
• Total porosity values in undisturbed samples ranged from 0.41-0.55 for the Phase 2
Cells 2A-2E and 0.39-0.61 for Phase 2 Cells 2F-2H. The porosity values for Phase 3 were
established in DHR from soil sample particle size distributions and published procedures.
These values ranged from 0.03-0.38.
• Undisturbed saturated hydraulic conductivity values ranged from 1.10x10-4 cm/sec to
8.08x10-8 cm/sec. (Appendix D)
2.4 AQUIFER TESTING
In -situ aquifer testing was performed during previous DHR investigations. A summary of the aquifer
testing results is discussed in section 3.4.2.
2.5 GROUNDWATER LEVEL MEASUREMENTS
Groundwater monitoring wells are present within and adjacent to the Phase 4 landfill expansion
area. From the wells, the static groundwater level (aka depth to water) is measured and recorded
during the course of routine monitoring for the Landfill. Depth to water measurements are recorded
prior to well sampling for each monitoring event.
Historical static water level measurements collected during routine semi-annual groundwater
monitoring events that are pertinent to the Phase 4 investigation are provided in Table 2. In addition,
historic groundwater elevations from previous investigations are included in Appendix E for
piezometers and groundwater monitoring wells located within or near the Phase 4 expansion area.
A summary of our findings from the groundwater level measurements is as follows:
• The groundwater table elevations within the monitoring wells installed within the Phase 4
investigation area are generally higher than the top of bedrock elevations.
• The groundwater table elevations within the piezometers have generally been higher
than the top of bedrock elevation with the exception of OW-29, OW-28, and A-71.
• The saprolite and fractured bedrock are the primary water -bearing units beneath the
Landfill.

3.0 HYDROGEOLOGIC EVALUATION
To further characterize the hydrogeology beneath the Phase 4 landfill expansion area, the following
data evaluation was performed: evaluation of groundwater elevations; assessment of groundwater
flow direction; calculation of groundwater flow rate; vertical gradient assessment; and identification
of top of bedrock surface. Data from previous DHR investigations were used for these data
evaluations.
3.1 GROUNDWATER FLOW DIRECTION ASSESSMENT
Groundwater flow at the Landfill property is generally from the east to the west, toward Rocky River,
as shown on the April 2020 Groundwater Statistical Analysis Report (Jett 2020) groundwater
contour map that is included as Figure 10. Most borings from previous investigations have been
abandoned; therefore, for locations in which a groundwater elevation could not be measured during
the course of routine monitoring, the historically reported groundwater elevations (Appendix E) were
used for purposes of constructing groundwater flow contour lines. Groundwater contours were
generated using AutoCAD surface mapping system software and altered utilizing professional
judgement. The generated groundwater surface contours for the Phase 4 landfill expansion are
shown on Figure 11. Observations regarding the direction of groundwater flow within the proposed
Phase 4 landfill expansion area is as follows:
• Groundwater contours mimic topographic contours.
• Groundwater flows from north to south toward Rocky River.
• A drainage control feature was originally located within the proposed Phase 4 expansion
area.
The groundwater flow direction within the Phase 4 landfill expansion area is shown on Figure 11.
3.2 GROUNDWATER ELEVATION EVALUATION
Groundwater elevation data from the groundwater monitoring wells, piezometers, and borings
installed throughout the Landfill for previous DHR investigations were compiled and provided in
Appendix E. Based on this historical data, the maximum -recorded groundwater elevation was
identified as the seasonally high groundwater elevation for each location. The seasonally high
groundwater elevations, as well as source and dates for the data are presented in Table 3. From this
data, a seasonal high groundwater contour map was created, included as Figure 11. The contours
were generated using AutoCAD surface mapping system software and altered utilizing professional
judgement. Observations regarding the seasonally high water table within the proposed Phase 4
landfill expansion area is as follows:
• High groundwater levels typically occurred during the spring semi-annual monitoring
events.
• The upper -most aquifer is first encountered within the saprolitic overburden with the
exception of OW-28, OW-29, A-7, and A-86.
• The saturated zone is also found in the PWR and fractured upper bedrock.
CMS LF V Phase 4 www.scsenaineers.com
Design Hydrogeologic Report 12

• MW- 24 and MW-17 are located near an existing drainage feature where groundwater is
expected to be above the top of bedrock.
• The seasonally high water table mimics the surface topography.
3.3 VERTICAL GRADIENT ASSESSMENT
The vertical hydraulic gradients for the monitoring well clusters were calculated to assess whether
the area is a zone of groundwater discharge or recharge. The vertical hydraulic gradient is the
change in head (groundwater elevation) per unit of vertical distance (elevation of the middle of the
well screen) between wells. The vertical hydraulic gradient was calculated using the difference
between groundwater elevations measured in well pairs during previous investigations. Vertical
gradient calculations are shown in Appendix F.
The calculated historical vertical hydraulic gradient that will most closely correlate to Phase 4 is the
P-11 to P-31 comparison from the Phase 3 DHR, is upward, and has a reported range of -0.062 to -
0.051 feet per foot. A positive vertical gradient indicates a vertically downward hydraulic gradient
(recharge zone) and a negative gradient indicates a vertically upward hydraulic gradient (discharge
zone). This indicates that within the Phase 4 limits a discharge zone is present.
Water level data from previously installed nested monitoring well pairs indicate that upward
gradients exist near and within drainage features. Downward vertical gradients have been observed
during previous investigations in nested wells outside of the influence of the Landfill's drainage
features.
3.4 GROUNDWATER FLOW RATE CALCULATIONS
An aquifer's flow rate is influenced by the hydraulic gradients, hydraulic conductivity, and porosity of
the aquifer. Details regarding each component of the flow rate calculation and groundwater flow rate
calculations for the upper -most aquifer are presented in the following sub -sections.
3.4.1 Horizontal Hydraulic Gradient
The horizontal hydraulic gradient (i) is the change in head (dH) per unit of distance (dQ in the
direction of groundwater flow. Hydraulic gradient is the one factor for groundwater velocity
calculations that may change over time. Horizontal hydraulic gradients were calculated using the
difference between groundwater contour lines within the Landfill property as shown on the
April 2020 Groundwater Contour Map (Figure 10). The hydraulic gradients used for groundwater flow
rate calculations were 0.022 feet per foot and 0.019 feet per foot depending on location. The semi-
annual groundwater monitoring calculated groundwater flow velocity for the Landfill from April 2012
to October 2020 provided in Appendix G.
3.4.2 Hydraulic Conductivity
Hydraulic conductivity (K) is the measure of a specific geological unit's ability to transmit water and is
necessary to calculate groundwater rate. It is expressed as the volume of water that will move in a
unit of time at a hydraulic gradient through a unit area measured at right angles to the direction of
flow.
The hydraulic conductivity of the upper -most aquifer for Phase 4 is derived from previous
investigations. A summary of the historical aquifer test results is shown in Appendix H. Hydraulic
CMS LF V Phase 4 www.scsenaineers.com
Design Hydrogeologic Report 13

conductivities for piezometers and groundwater monitoring wells in and around the proposed Phase
4 were reviewed and included in the site -wide groundwater flow rate calculations.
In summary, hydraulic conductivity (Ks) values for piezometers within the soil/saprolite aquifer (in
Phase 3) vary from 4.71 x 10-6 cm/sec (P-14) to 1.08 x 10-6 cm/sec (P-73), within the PWR aquifer
from 5.53 x 10-6 cm/sec (P-16) to 9.16 x 10-7 cm/sec (P-60), and within the bedrock aquifer from
4.99 x 10-5 cm/sec (P-52) to 2.78 x 10-6 cm/sec (P-13).
3.4.3 Porosity
Porosity is the measure of a material's pore space through which water can flow. The upper -most
aquifer at the Landfill is found within the saprolite/bedrock interface or within the fractured bedrock.
Based on porosity values utilized for previous DHR investigations, effective and total porosity values
range widely as shown in Appendices D and H.
3.4.4 Groundwater Flow Rate
The groundwater flow rate for Phase 4 was calculated using the Darcy equation shown below.
rM
Vx =
ne
where: vx = groundwater flow rate
K = hydraulic conductivity
i = horizontal hydraulic gradient
n = total porosity of the aquifer
As shown in Appendix G, groundwater flow rates were calculated utilizing the following data
• An average horizontal hydraulic gradient of 0.021.
• The saprolite (1.10x10-3 cm/sec), PWR (2.Ox10-4cm/sec), and bedrock (7x10-5 cm/sec)
values for hydraulic conductivity.
• A total porosity value of 0.16 for saprolite, 0.20 for PWR, and 0.07 for bedrock.
The Landfill's April 2020 water quality monitoring event had groundwater flow rates ranging from 22
feet/year to 135 feet/year. Historical groundwater flow from routine monitoring events range from
21 feet/year to 146 feet/year. Groundwater flow rates from the Phase 2 Cells 2F-2H DHR range from
10.95 feet/year to 200.75 feet/year in upland areas, 7.3 feet/year to 120.45 feet/year in the mid
surface elevations, and 124.1 feet/year to 182.5 feet/year in the lower surface elevations.
Therefore, the April 2020 flow rate range is consistent with flow rates previously documented.
3.5 TOP OF BEDROCK EVALUATION
A bedrock contour map was created for the Phase 4 landfill expansion area. The bedrock contour
map was created by compiling the top of bedrock elevation data from groundwater monitoring wells,
piezometers, and borings installed within and near the Phase 4 area from the various investigations
previously completed for the Landfill. The top of bedrock elevations for locations within the Phase 4
CMS LF V Phase 4 www.scsenaineers.com
Design Hydrogeologic Report 14

investigation area are shown in Table 4. The top of bedrock was interpreted as the point at which
auger refusal was identified during drilling, or as reported in the table and boring logs provided in
Appendix I.
A top of bedrock surface contour map was generated using AutoCAD surface mapping system
software and adjusted utilizing professional judgement and is included as Figure 12. Observations
regarding the top of bedrock surface within the proposed Phase 4 landfill expansion area is as
follows:
• Depth from the ground surface to the top of the bedrock unit ranges from 14 feet at
boring A-72 location up to 30 feet at monitoring well MW-24 location. The depth to
bedrock is generally shallow in drainage features and deeper beneath topographic highs.
• The bedrock surface within the Phase 4 area generally mimics the surface topography.
3.6 VERTICAL SEPARATION ASSESSMENT
A municipal solid waste landfill (MSWLF) unit shall be constructed so that the post -settlement
bottom elevation of the base liner system is a minimum of four feet above the seasonal high ground-
water table and bedrock datum. To comply with this requirement, seasonally high groundwater and
top of bedrock surface contour maps are created as presented in Sections 3.2 and 3.5, respectively.
These maps will be provided to the landfill design engineer for the development of base grades for
the proposed Phase 4 waste unit.
4.0 WATER QUALITY AND METHANE GAS MONITORING
An updated groundwater and methane gas monitoring plan that included development of Phase 4
was submitted to NCDEQ on October 8, 2020 and were subsequently approved. These plans
included the continual monitoring of MW-33 and MW-34 groundwater monitoring wells,
abandonment of MW-24, and the relocation of wells MW-17 and MW-17A down gradient of the
proposed Phase 4 expansion area. Relocated wells MW-17 and 17A will be installed following
construction the the Phase 4 landfill expansion. Well abandonment and installation will be
completed and the proper completion records and certifications submitted to NCDEQ as delineated
in 15A NCAC 2C Rule. The Landfill's current and proposed monitoring network is shown on Figure 2
and 3.
A certification by a Licensed Geologist that all borings at the site that have not been converted to
permanent monitoring wells will be properly abandoned in accordance with the procedures for
permanent abandonment of wells.
5.0 CONCLUSIONS
The geologic and hydrogeologoc conditions for the proposed Phase 4 landfill expansion are
consistent with previous DHR investigations completed for MSWLF units constructed at the Charlotte
Motor Speedway (CMS) Landfill V. No unusual or unexpected geologic features were identified within
the Phase 4 landfill expansion area.
Groundwater and bedrock surfaces typically mimic the surface topography across the Landfill.
Groundwater flow direction is from north to south across Phase 4 towards Rocky River. Groundwater
gradients have exhibited both upward and downward vertical flows across the Landfill. As a result, to
be relocated shallow and deep well pair, MW-17 and MW-17A, are identified as the down -gradient

compliance point for Phase 4, once constructed. This well relocation is discussed in the previous
Section 4.0.
Based on the findings presented in this DHR and previous DHR submittals, the Phase 4 area is
considered suitable for expansion of the Charlotte Motor Speedway Landfill V.

** insufficient material present to run the hydrometer test
The grain size defining the clay fraction used in this work is 0.002 mm (2 microns), as referenced by Atterberg (1905), Terzaghi and Peck (1948),
Lambe and Whitman (1969), Holtz and Kovaks (1981). The USDA system used 0.005 mm as the cutoff until 1935, but since changed to 0.002 mm.
Some practitioners still use 0.005, but the USCS has adopted 0.002.
The laboratory reported both USCS and USDA classifications, for which USCS classifications were reported in the original version of this table.
The grain size distributions have been checked and reported values are consistent with USCS classification cutoff values.
*Effective porosity values were determined from the grain size distribution referencing Fetter (1988), which involved using different cutoff values and
a ternary diagram to determine specific yield, referenced in USGS Water -Supply Paper 1662-D (1967). Refer to the supplemental data in Appendix B.

* Rock Fragments Observed in Sample
3.5 Groundwater
Groundwater measurements were obtained in auger borings at the termination of drilling,
near 24 hours after drilling, and bi-weekly for a total of up to five groundwater
measurements. As previously mentioned, the observation wells consisted of generally 5
to 10-foot machine slotted screens. All of the auger borings that penetrated the
groundwater not converted to observation wells had a temporary standpipe installed.
Eight of the observations wells located outside the landfill (including 5 rock core nested
locations) were installed as Type II monitoring wells for potential use as future
groundwater monitoring wells.
�l Groundwater levels were measured using an electronic water level indicator from the top
of the PVC standpipe. The top of the PVC standpipe as well as ground surface elevations
were surveyed by F.D. Lawrence & Associates, P.A. The groundwater level
measurements and elevations are presented in Table 4.
Groundwater levels in the area of Cells 2C through 2E will continue to be monitored on
a monthly basis until these areas are ready for construction. The auger borings and
observation wells located within the footprint of Cell 2A and 2B will be abandoned in

** insufficient material present to run the hydrometer test
The grain size defining the clay fraction used in this work is 0.002 mm (2 microns), as referenced by Atterberg (1905), Terzaghi and Peck (1948),
Lambe and Whitman (1969), Holtz and Kovaks (1981). The USDA system used 0.005 mm as the cutoff until 1935, but since changed to 0.002 mm.
Some practitioners still use 0.005, but the USCS has adopted 0.002.
The laboratory reported both USCS and USDA classifications, for which USCS classifications were reported in the original version of this table.
The grain size distributions have been checked and reported values are consistent with USCS classification cutoff values.
*Effective porosity values were determined from the grain size distribution referencing Fetter (1988), which involved using different cutoff values and
a ternary diagram to determine specific yield, referenced in USGS Water -Supply Paper 1662-D (1967). Refer to the supplemental data in Appendix B.

Notes:
Estimated Velocity Determined as Follows by Darcy's Law: Water Elevations measured 5/11/07 ***Effective porosity values are derived from Table 2 for soils, including PWR;
v = ki/ n, where v = velocity, k = hydraulic conductivity except P-9 (4-17-07) and P-11 (1/29/03) values for bedrock derived from Driscoll, Groundwater and Wells, 1986 (pg. 67),
i = hydraulic gradient, and n = effective porosity Domenico and Schwartz, Physical and Chemical Hydrogeology, 1990 (pg. 21),
**upper syenite bedrock is highly weathered Freeze and Cherry, Groundwater, 1979 (pg. 37); the design values are collaborated
*Based on Hvorslev's method, see Table 3 by earlier site studies S&ME, 1999 and are conservative e.., on the high side).

using the tangent to ellipse rule based on the ratio of the square root values
of the two scales.
2) In addition, the ratio of the length to cross -sections (1600 feet to 3200 feet)
to the depth of the cross -sections (70 feet to 100 feet) is approximately 25
to 30. This results in a very skewed graphic, that combined with the
distance between monitored locations (due to the size of the site), resulting
interpretations of the data or the generated flow lines may vary greatly, and
may not represent an accurate groundwater flow regime.
3) The hydraulic conductivity of the hydrologic units (Table 2) generally
decreased with depth. To show flow lines and equipotential lines on a
cross-section where changes in hydraulic conductivity values occur, the
equipotential lines (and flow lines) must be refracted using the tangent law.
The geometric average hydraulic conductivity values decrease from the
upper unit to the next lower unit by the following:
Saprolite to PWR: 0.20
PWR to Upper Bedrock: 0.35
Upper to Lower Bedrock: 0.04
While each of these factors would not prohibit the construction of flow nets, the combined
effect of these factors present a very complex and challenging task. In addition, the
complexities of generating the flow nets may also yield an inaccurate representation of
the actual groundwater flow regime.
