EXECUTIVE SUMMARY
S&ME, Inc. (S&ME) is contracted by the Sorrell Grading Company and The Estate of Mr. Clyde E. Sorrell, Senior,
(Sorrell) to provide semi-annual groundwater and surface water monitoring services at Sorrell Landfill located off
of Smith Road (S.R 1303) near Apex, North Carolina. This monitoring event was performed on October 31, 2022.
These services were performed in general accordance with the Water Quality Monitoring Plan (WQMP) prepared
in June 1996 by Trigon Engineering Consultants, Inc. as modified by the request for additional sampling locations
made by representatives of NCDEQ-DWM, and NCDEQ's Water Quality Monitoring Requirements Letter, dated
April 29, 2003. The landfill is currently in an assessment monitoring program because of the detection of
contaminants in monitor well samples in excess of North Carolina Groundwater Protection Standards.
During the October 2022 monitoring event, one background well (MW-1 R), five compliance wells (DW-1, MW-5,
MW-6, MW-8 and MW-9), one off -site assessment well (GP-10) and two surface water sampling locations (SW-1
and SW-2) were sampled. Based on groundwater elevations measured during the October 2022 sampling event,
the overall groundwater flow at the landfill is to the northwest at an average velocity of 35.48 feet per year (ft/yr).
Deep well DW-1 is installed within the bedrock aquifer near MW-8 along the facility's southern boundary to
delineate the vertical extent of landfill contaminants that may be migrating from the landfill cell. A comparison of
groundwater elevations in DW-1 and MW-8 indicates that an upward gradient continues to exist between the two
water -bearing zones in the vicinity of these wells. Due to the upward gradient in the vicinity of DW-1,
contaminants are unlikely to migrate downward. Current analytical data of groundwater quality at DW-1 supports
this premise.
Groundwater and surface water samples were analyzed for constituents listed in 40 CFR 258, Appendix I
Constituents for Detection Monitoring (Appendix 1). The groundwater samples from monitor wells MW-8 and
GP-10 were additionally analyzed for the Appendix II List of Hazardous Inorganic and Organic Constituents
(Appendix II) for assessment monitoring. The laboratory analytical results for the groundwater samples were
compared to the maximum allowable concentrations promulgated in the State of North Carolina groundwater
standards as presented in 15A North Carolina Administrative Code, Subchapter 2L (15A NCAC 2L), hereafter
referred to as the 2L Standards or the Solid Waste Groundwater Protection Standards (GWPST) established in
accordance with the Solid Waste Rules Section .1634(h). The surface water sample analytical results were
compared to the maximum allowable concentrations promulgated in the North Carolina Surface Water Class C
standards found in 15A NCAC 2B (213 Standards).
From the groundwater samples collected in October 2022, five constituents were detected at concentrations
greater than their respective 2L Standards: benzene, tetrachloroethene, trichloroethene, vinyl chloride, and cobalt.
The constituent chlorodibromomethane was detected above the 2L Standard in the trip blank and equipment
blank but was not detected in any groundwater samples. No organic constituents on the Appendix II list were
detected above the laboratory method detection limits (MDLs).
For surface water samples, the metals barium and vanadium were detected above the MDL in the samples from
the upstream (SW-1) surface water monitoring location and from the downstream (SW-2) surface water
monitoring location, however both constituents in both locations were less than their respective 2B Standard. The
VOC 1,4-dioxane was detected greater than the laboratory MDL, but less than the 2L Standard from the surface

water sample from the downstream (SW-2). VOCs acetone and methyl -ethyl -ketone were detected above the
MDL but below the 2B Standard in the upstream (SW-1). No other targeted constituents were detected above
their respective laboratory MDLs in the two surface water samples collected.
The frequency and number of metals detected at the site have declined since low -flow sampling procedures were
implemented in 1999. The inorganic constituents that continue to be detected at concentrations greater than NC
Water Quality standards appear to represent naturally occurring concentrations in groundwater. It is
recommended that the use of low flow sampling methods be continued and that monitoring for inorganics be
limited to Appendix I inorganic constituents (no cyanide or sulfide) at the facility's monitor wells and surface water
monitoring points.
VOCs have been detected in samples collected from well MW-8 since the well was installed in 2001. The
consistent detection of VOCs at MW-8 indicates that a source or sources of VOCs may be present at or near this
well. Additional assessment of surrounding properties was conducted in October 2008 to further evaluate the
extent of the groundwater contamination near MW-8. VOCs were detected above the 2L Standards in the off -site
groundwater assessment monitor wells in October 2008 and subsequent monitoring events. An assessment of
corrective measures and corrective action should be performed to address the groundwater contamination near
MW-8. In the meantime, it is recommended that groundwater monitoring at MW-8 continue to monitor for
Appendix II VOCs. Sampling of the off -site assessment wells in the vicinity of MW-8 (i.e., GP-8, GP-9, and/or GP-
10) should continue to be included as part of the regular compliance monitoring to monitor the extent, movement
and concentration of chemicals in groundwater in the general vicinity of MW-8.
S&ME recommends that semi-annual assessment monitoring of groundwater and surface water be continued at
the Sorrell Landfill. Currently, six monitor wells and two surface water locations are sampled at Sorrell Landfill to
fulfill the monitoring requirements as required by North Carolina Solid Waste Management Rule .1634.
It is our understanding that the Wake County Department of Environmental Services, Water Quality Division
regularly samples the potable wells on the adjacent properties to the south of the landfill (Dye and Herndon
properties) as a precautionary measure to protect the users of these potable wells. S&ME recommends the results
of this sampling event be provided to Wake County for consideration in deciding protective measures for the
nearby potable wells and their users.

1.0 Introduction
S&ME, Inc. (S&ME) was contracted by the Sorrell Grading Company and The Estate of Mr. Clyde E. Sorrell, Senior,
(Sorrell) to provide groundwater and surface water monitoring services at Sorrell Landfill located off of Smith Road
(S.R 1303) near Apex, North Carolina (Figure 1). The sampling for this monitoring event was completed on
October 31, 2022. The services were performed in accordance with the facility's revised Water Quality Monitoring
Plan (WQMP) prepared in February 1996 by Trigon Engineering Consultants, Inc. Section 4.0 of the WQMP
outlined the sampling and analysis plan (SAP) to be used to monitor groundwater and surface water in the vicinity
of the landfill. The landfill is currently in an assessment monitoring program because of the detection of
contaminants in monitor well samples at concentrations exceeding 2L Standards.
In accordance with the approved WQMP, four baseline sampling events were performed in May, June, July, and
August 1999. During each of those sampling events, groundwater samples were collected from two upgradient
(background) wells (MW-1 R and MW-4), and three downgradient (compliance) wells (MW-5, MW-6, and MW-7).
A surface water sample was collected at one down -gradient surface water monitoring point (SW-2). Groundwater
and surface water samples collected during the four 1999 sampling events were analyzed for constituents listed in
40 CFR 258, Appendix I Constituents for Detection Monitoring (Appendix 1). The sample results and subsequent
statistical analyses performed for the 1999 sampling rounds constitute the baseline for the semi-annual sampling
events being conducted during the post -closure period. The baseline sample results submitted to the North
Carolina Department of Environmental Quality, Division of Waste Management (NCDEQ-DWM) on April 9, 2001,
indicated that one or more constituents listed in Appendix I were detected at statistically significant levels.
Based on the results of the baseline sampling events, assessment monitoring was conducted at Sorrell Landfill
during four subsequent sampling events (April 2001, December 2001, April/May 2002, November 2002) for the
constituents listed in 40 CFR 258, Appendix II List of Hazardous Inorganic and Organic Constituents (Appendix 11) as
promulgated in Section .1634.
At the request of the DWM, beginning with the December 2001 sampling event and continuing with the April/May
2002 and November 2002 events, S&ME also collected groundwater samples from two new monitor wells- one
shallow well (MW-8) and one deep well (DW-1), that were installed along the facility's southern property
boundary. Both wells are located approximately between the southern edge of the landfill cell and the closest
residential well. Based on measured monitor well water elevations obtained during performance of the 2001 and
2002 sampling events, and potentiometric mapping of the shallow aquifer, it appears that monitor wells DW-1
and MW-8 are hydraulically cross -gradient of the landfill. However, for the purposes of this report, wells MW-8
and DW-1 are reported as compliance wells.
Following the November 2002 sampling event, S&ME recommended revising the number of sampling locations,
the sampling frequency, and the laboratory analysis performed at each sampling location. In a letter dated April
23, 2003, the Section approved these revisions. Based on the revised monitoring plan, one background well (MW-
1 R), five compliance wells (DW-1, MW-5, MW-6, MW-7, and MW-8), and two surface water locations (SW-1 and
SW-2) were to be monitored. Subsequently, S&ME determined that monitor well MW-7 was located either in or
immediately adjacent to the landfill wastes. Therefore, S&ME recommended, on behalf of Sorrell, that the
sampling of MW-7 be suspended and that a new compliance well be installed in that area. In a letter dated May
10, 2004, the Section concurred with that opinion. Monitor well MW-9 was installed on September 18, 2007 and

has replaced MW-7 as the compliance well along the northern portion of the landfill. Well MW-7 remains in place
for measuring water levels.
This report presents the methods used and the results of the sampling event conducted by S&ME during the
October 2022 sampling event at the facility, which included the sampling of one background well (MW-1 R), five
compliance wells (DW-1, MW-5, MW-6, MW-8, and MW-9), one off -site assessment well (GP-10) and two surface
water sampling locations (SW-1 and SW-2).
2.0 General Physiography
Some of the general background information presented in this section has been compiled from the Water Quality
Monitoring Plan prepared in June 1996 by Trigon Engineering Consultants, Inc., from the Preliminary Explanatory
Text for the 1985 Geologic Map of North Carolina (1988) prepared by The North Carolina Geological Survey; and
from Geology of the Carolinas (1991) by Horton and Zullo. The information presented herein has been modified
for brevity and is intended to provide general background information, particularly regarding regional
topography, geology, and hydrogeology.
2.1 Site Topography
The landfill site is located southeast of Apex, North Carolina in southwestern Wake County (Figure 1). At its
highest point, the landfill extends approximately 30 to 45 feet in elevation above the surrounding natural ground
surface. The natural ground surface elevations at the site prior to construction of the landfill ranged from 400 to
460 feet above Mean Sea Level (MSL). The current landfill cap surface slopes gently downward to the southwest
to an approximate elevation of 490 feet above MSL (Figure 2).
2.2 Regional Geology
The site is located in the eastern portion of the Piedmont physiographic province. In Wake County, the land
surface is evenly divided between flat to gently rolling inter -stream areas and valleys. Soil and weathered rock
typically extend downward to depths up to 60 feet below ground surface (ft-bgs). Outcrops of hard bedrock are
rare, and most are confined to streambeds and excavations.
Bedrock at the site area has been characterized as part of the Carolina Slate Belt. The Carolina Slate Belt in this
portion of the county consists primarily of predominately low-grade felsic meta -volcanic and meta-epiclastic
rocks, presumed to have originated from a sub -aqueous, volcanic arc environment. Primary rock types include
metamorphosed argillites, mudstone, volcanic sandstone, and conglomerate. Approximately one-half mile to the
west, an unconformity identified as the Jonesboro Fault separates the Carolina Slate Belt from Triassic claystone
and siltstone sediments.
Cretaceous -age Coastal Plain sediments immediately overlie the basement rocks in the southern and eastern
portion of the site. Middendorf units include deposits of sand, sandstone, and mudstone. Beds are laterally
discontinuous with inter -fingering cross -bedding common in the upper units.

2.3 Site Geology and Hydrogeology
The site lies on the western edge of the Neuse River basin. Surface water run-off from the site flows to the west
into Middle Creek. Surface water then flows to the south and east toward the confluence of Middle Creek and the
Neuse River near Smithfield, NC.
The unconfined aquifer in western Wake County is typically present in the unconsolidated subsurface residual soils
to an approximate depth of 30 ft-bgs, depending on the topography. Shallow groundwater flow patterns in the
vicinity of the landfill have been evaluated through a series of shallow downgradient monitor wells finished at
depths ranging between approximately 14 to 27 ft-bgs and approximately 45 ft-bgs in an upgradient well (MW-
1 R). The depth to groundwater varies from just below the ground surface in the downgradient wells located on
the western side of the landfill to approximately 22 ft-bgs on the eastern (upgradient) side of the landfill at MW-
1 R.
A nested well pair, one shallow well (MW-8) and one deep well (DW-1) is approximately located between the edge
of the landfill cell and residential wells installed along the facility's southern property boundary line (Figure 2).
The shallow monitor well (MW-8) was installed into the overlying sandy silt and is believed to monitor the same
shallow unconfined aquifer monitored by the other wells previously installed at the site. Monitor well DW-1 is the
only well installed into the bedrock aquifer at the site.
At the location of DW-1, the soil immediately beneath the ground surface was classified as sandy silt and silt to a
depth of approximately 54 feet bgs. Underlying the sandy silt and silt is partially weathered meta -volcanic and
metasedimentary rock of various degrees of weathering, extending to approximately 66 feet bgs, where more
competent bedrock was encountered. The underlying competent rock is bluish schist with quartz, muscovite,
biotite, and hornblende minerals, and was observed to a depth of 101 feet bgs, where the deep boring was
terminated. During installation of DW-1, water -bearing fractures were observed in the bedrock at 78 feet bgs and
99 feet bgs. Based on field estimates by S&ME, the water -bearing zone at 78 feet bgs produced approximately
one gallon per minute (gpm) and the water -bearing zone at 99 feet produced approximately six gpm.
2.4 Groundwater Table
Prior to sampling for this monitoring event, each well was examined for its general integrity, including protection
from surface water inflow, well identification tag, vented cap, lock, and general well security. Each well was
opened and the depth to the water in the well was measured from a referenced mark on the top of the PVC well
casing using an electronic water level indicator. The water elevation at each well was calculated by subtracting the
depth measurement from the elevation of the referenced top of casing. Table 1 presents data on the depth to
groundwater measurements and groundwater elevation calculations for each of the monitor wells sampled during
the October 2022 sampling event and the groundwater elevation calculations at each of the methane monitor
wells.
The shallow groundwater is defined in this report as the water -bearing zone located in the soil regime beneath
and in the vicinity of the landfill. The depth to the shallow groundwater was measured in the background well
(MW-1 R) and in the compliance wells (MW-5, MW 6, MW-8 and MW-9) during the sampling event. Depth to
groundwater was also measured in the deep compliance well DW-1. However, this well monitors a separate
water -bearing zone within the bedrock aquifer and is not representative of the shallow groundwater. In addition

to the depth -to -water measurements taken at these groundwater monitor wells, depth -to -water measurements
were also taken at fourteen groundwater piezometers (GP-7, GP-7D, GP-8, GP-9, GP-10, GP-1 OD, GP-11, GP-12,
GP-12D, GP-13, GP-13D, GP-14, GP-15 and GP-16) installed along the southern boundary of the landfill. These
piezometers were used to assess groundwater quality and groundwater elevations in the vicinity of MW-8 and
methane gas monitor wells to supplement the water elevation data. A complete list of monitor wells and methane
gas monitor wells with the associated groundwater elevation calculation is presented on Table 1.
2.5 Hydraulic Gradient and Groundwater Flow Velocity Calculations
The well water elevations and our interpretation of the water table surface expressed as a potentiometric map
along with groundwater flow direction are shown on Figure 2. Based upon the groundwater elevations in the
vicinity of the landfill cell, groundwater in this area is projected to flow northwest toward an unnamed tributary of
Middle Creek, which is consistent with historical groundwater potentiometric data.
Hydraulic Gradient
The average horizontal hydraulic gradient was calculated from three-point calculation solutions using two well
sets of groundwater elevation data measured during the October 31, 2022 sampling event and by applying the
following equation (Driscoll, 1986):
Where:
i=hl-h2
i = Hydraulic gradient
h1 - h2 = Difference in hydraulic head (feet)
L = Distance along flow path (feet)
The three-point calculation is used to estimate the hydraulic gradient perpendicular to a groundwater
potentiometric contour of equal elevation determined from high, intermediate, and low groundwater elevations at
three monitor wells. The gradient calculated perpendicular to the equal elevation contour plotted from the well
set is representative of a true gradient rather than the apparent gradient that is estimated from a two -point
gradient calculation. Based on the Driscoll gradient equation and using a third groundwater elevation to plot the
equal elevation contour, the distance L can be measured between h1 and h2 perpendicular to the equal elevation
contour to estimate the true hydraulic gradient for the three groundwater elevation data points. The average
horizontal hydraulic gradient is typically calculated from two three-point solutions using well sets MW-1 R, MW-9,
and MW-4, and MW-8, MW-5 and MW-6. Using MW-1 R, MW-4, and MW-9; and MW-8, MW-5, and MW-6 the
average hydraulic gradient is estimated to be 0.0277 ft/ft. This gradient is similar to the hydraulic gradient
previously calculated for the site. The hydraulic gradient calculations are included in Appendix IV.
Groundwater Flow Velocity
An approximate average linear groundwater flow velocity (v) may be calculated by the equation (Freeze and
Cherry, 1979):
v = Ki

Aquifer slug tests were previously performed in monitor wells MW-6, MW-7, MW-8, MW-9 and DW-1 at the site
by S&ME using rising and falling head test techniques. The slug test data were used to estimate the hydraulic
conductivity of the sediments in the surficial aquifer intersected by the screened intervals of the monitor wells
tested. The aquifer test data were analyzed by the Bouwer and Rice Method. As summarized on Table 2, the
average hydraulic conductivity values previously measured at the site ranged from 4.00x10-4 centimeters per
second (cm/sec) to 1.86x10-4 cm/sec.
The groundwater flow velocity was calculated for the site using the average hydraulic conductivity values
measured at the site; the average hydraulic gradient of 0.0277 ft/ft, calculated from the three-point calculation
described above; and an effective porosity of 20%. Groundwater flow velocities calculated during the October 31,
2022 sampling event ranged from 27.46 feet per year (ft/yr) between monitor wells MW-8 and MW-5 to 53.14
ft/yr between monitor wells MW-1 R to MW-9, resulting in an average velocity of 38.20 ft/yr based on the
calculations that were performed using the equation and input values above. This velocity is similar to previous
groundwater velocities calculated for the site. The calculated hydraulic gradients and groundwater flow velocities
are presented in Table 3.
As previously discussed, monitor wells MW-8 and DW-1 were installed in December 2001 along the facility's
southern boundary based on hydrologic data available at the time and the relative position of the landfill and the
nearby potable wells. Monitor well MW-8 was intended to serve as a point of compliance between the landfill and
residential wells installed adjacent to the site's southern property boundary. However, as shown on Figure 2,
static water levels measured during the October 2022 sampling event indicate that MW-8 may be located
hydraulically cross -gradient of the landfill cell.
DW-1 is the only monitor well installed on site within a separate water -bearing zone contained within the bedrock
aquifer and was installed to delineate the vertical extent of landfill contaminants that may be migrating from the
landfill cell. As shown on Table 1, the groundwater elevation in DW-1 was observed to be 3.28 feet higher than
the groundwater elevation in MW-8 during the October 2022 sampling event. This difference in groundwater
elevations, representing hydraulic head, indicates that an upward gradient exists between the two water -bearing
zones in the vicinity of these two wells. This upward flow component has been observed at these two wells since
they were installed in December 2001.
2.6 Surface Water
The site is located just south of an unnamed tributary that flows southwest into Middle Creek. Middle Creek flows
to the southeast, eventually emptying into the Neuse River near Smithfield, North Carolina. The unnamed tributary
is the only surface body to receive surface water runoff from the landfill. S&ME selected two surface water
collection points along the unnamed tributary. One sample collection point (SW-1) is located hydraulically

upgradient from the landfill. The other sample collection point (SW-2) is located hydraulically downgradient from
the landfill. During the October 2022 sampling event, surface water samples were collected from both sample
locations. Surface water sample collection points SW-1 and SW-2 are shown on Figure 2.
3.0 Sampling Program
In accordance with 15A NCAC 13 B, § .1632, and the approved groundwater and surface water SAP for the facility,
the following sections describe the procedures used for the collection of groundwater and surface water samples
during the sampling event.
S&ME sampled surface water from the up -gradient and down -gradient collection points along an unnamed
tributary of Middle Creek (SW-1 and SW-2), one background well (MW-1 R), four shallow and one deep
compliance wells (MW-5, MW-6, MW-8, MW-9 and DW-1) on October 31, 2022. One shallow off -site
groundwater assessment well (GP-10) was also sampled during the October 2022 sampling event. The monitor
wells at the landfill were sampled using a low -flow peristaltic pump equipped with polyethylene tubing. Prior to
sampling each of the wells, the groundwater was purged at a rate of approximately 200 milliliters per minute until
the turbidity was reduced to less than 10 Nephelometric Turbidity Units (NTUs) where it was achievable.
Stabilization of the selected field parameters was defined as a variance of less than 10 percent in three successive
readings recorded five minutes apart. Monitor well MW-1 R was sampled with a polyethylene bailer due to an
increased depth -to -water.
The surface water samples from the creek were collected using laboratory -supplied 1-liter bottles dipped directly
into the stream as collection devices. The water was then poured into laboratory -prepared vials and bottles.
At the completion of sampling, S&ME delivered the samples to Environmental Conservation (ENCO) Laboratories
in Cary, North Carolina for the following analytical lists:
MW-1 R, MW-5, MW-6, MW-9, DW-1, SW-1, and SW-2 were analyzed for constituents listed in Appendix 1
(40 CFR 258); and
• MW-8 and GP-10 were analyzed for constituents listed in Appendix II (40 CFR 258).
Laboratory analytical methods for Appendix I constituents included EPA Method 6010D/6020B (metals) and
Method 8260D volatile organic compounds (VOCs).
Laboratory analytical methods for Appendix II constituents included the Appendix I constituent list, plus Method
8270E (SVOCs), Method 7470A (mercury), Method 9014 (cyanide) and SM18 4500-52 D-2011 (sulfide). The
analytical results reported from this sampling event are discussed in subsequent sections of this report.
4.0 Field Parameters
Specific conductivity, pH, temperature, dissolved oxygen, oxygen reduction potential and turbidity were measured
in the field during well purging prior to sample collection. The normal sampling protocol includes purging the

shallow monitor wells with a peristaltic pump at a rate of approximately 200 mL/min. until the turbidity was
reduced to less than 10 NTUs (where achievable) and the selected field parameters stabilize. Field parameters
recorded just prior to collecting the groundwater samples are summarized in Table 4 and discussed in the
following sections.
4.1 Specific Conductivity
Specific conductivity (conductance) is a measurement of the ability of a solution to pass an electrical current.
Dissolved inorganic anions and cations such as chloride, nitrate, sulfate, phosphate, sodium, calcium, aluminum,
and iron increase the ability of water to carry a current. Therefore, conductivity is related to the amount of total
dissolved solids in the water. Waters percolating through a landfill cell typically become enriched with dissolved
solids, which are reflected by increased conductivity values. Typically, specific conductivity measures the presence
of common ions such as chloride and sulfate that are not necessarily indicative of hazardous constituents.
During the October 2022 sampling event, the specific conductance measured in the background well (MW-1 R)
was 0.027 milliSiemens per centimeter (mS/cm). Measurements in the one deep compliance well (DW-1) was
0.068 mS/cm. The specific conductance measured in the four shallow compliance wells (MW-5, MW-6, MW-8 and
MW-9) ranged from 0.021 mS/cm (MW-9) to 0.314 mS/cm (MW-5). The specific conductance measured off -site
assessment well (GP-10) was recorded as 0.095 mS/cm. The highest groundwater conductivity value (0.314
mS/cm) was measured in well MW-5. In general, conductivity readings are within the typical range of values that
would be expected to occur in shallow groundwater flow under natural conditions in the Eastern Piedmont region.
4.2 pH
The pH is a measurement of the hydrogen ion concentration. Values lower than pH=7 indicate increasingly acidic
conditions and values higher than pH=7 indicate increasingly alkaline conditions. The pH may strongly influence
the activity of certain chemical reactions and the solubility and mobility of metals.
The pH of the groundwater in the landfill wells was measured just prior to sample collection. The pH reading in
the background well (MW-1 R) was measured as 4.6. The pH measured in the four shallow compliance wells (MW-
5, MW-6, MW-8 and MW-9) ranged from 4.0 (MW-8) to 6.2 (MW-5). The pH in the off -site monitoring well (GP-
10) measured 5.5. The pH measured in the deep compliance well (DW-1) was recorded as 5.5. The pH values are
within the range that would be expected for shallow groundwater conditions in the Eastern Piedmont region.
4.3 Temperature
Groundwater temperature collected from the background well was 16.6°C (MW-1 R). Groundwater temperatures
recorded from samples collected from the four shallow compliance wells (MW-5, MW-6, MW-8, and MW-9)
ranged from 16.8°C (MW-9) to 18.7°C (MW-8). Temperature measured in the deep compliance well (DW-1) was
17.8°C. Temperature measured in the off -site assessment well (GP-10) was 17.9°C. Where the aquifer is near the
ground surface, groundwater temperatures may be closely related to seasonal temperature variations and the
presence or absence of vegetative ground cover.

Groundwater temperature directly affects the solubility of oxygen and other geochemical constituents. The
solubility of dissolved oxygen is temperature -dependent, with oxygen being more soluble in cold water than in
warm water.
Groundwater temperature also affects the metabolic rate of bacteria. Rates of biodegradation almost double for
every 100 C increase in temperature between 5 °C and 25 °C. Elevated temperatures may also be an indication of
significant microbiological activity.
4.4 Turbidity
Nephelometric turbidity was added to the list of field parameters for selected wells after the May 1999 sampling
event detected higher than expected concentrations of metals. Because the samples collected from monitor wells
MW-1 R and MW-6 during the initial baseline sampling event were turbid, the suspended soil particles present in
the groundwater could contribute to elevated concentrations of metals reported by the laboratory. Therefore, a
turbidity value of 10 NTUs or less was established as a goal while purging and prior to collecting a groundwater
sample. During the October 2022 sampling event, the target value of 10 NTUs was not achieved in monitor well
MW-1 R, which was recorded at > 1100 NTUs. Groundwater turbidity recorded just prior to sample collection in
the shallow compliance wells (MW-5, MW-6, MW-8 and MW-9) ranged from 0.00 NTUs (MW-8) to 3.27 NTUs
(MW-6). The turbidity level measured in the deep compliance well (DW-1) was recorded as 0.01 NTUs. The
turbidity level measured in the off -site assessment well (GP-10) was recorded as 3.56 NTUs.
5.0 Analytical Results
S&ME sampled one upgradient (background) well; four shallow and one deep downgradient (compliance) wells;
two surface water locations; and one off -site groundwater assessment well on October 31, 2022. The samples
were analyzed by ENCO Laboratories for constituents listed in Appendix I of 40 CFR 258. The groundwater sample
from compliance well MW-8 and the off -site assessment well GP-10 were additionally analyzed for Appendix 11
SVOCs, mercury, cyanide and sulfide. Laboratory analytical methods included EPA Method 6010D/6020B (metals),
Method 8260D (VOCs), Method 8270E (SVOCs), Method 7074A (mercury), Method 9014 (cyanide), and SM18
4500-52 D-2011 (sulfide). The analytical results for the groundwater and surface water samples collected and
analyzed in October 2022 are detailed below. A copy of the analytical laboratory report is provided in Appendix
III.
5.1 Groundwater
Groundwater sample analytical results were compared to the 2L Standards and to the GWPST established in
accordance with the Solid Waste Rules Section .1634(h). The analytical results for the October 2022 sampling
event are summarized on Table 5.
For the October 2022 sampling event, six constituents were detected at concentrations greater than their
respective 2L Standards: benzene (1.8 pg/L in MW-8 and 1.9 pg/L for DUPLICATE), tetrachloroethene (22 pg/L in
MW-8 and 24 pg/L for DUPLICATE), trichloroethene (14 pg/L in MW-8), vinyl chloride (2.9 pg/L in MW-8 and 3.4
pg/L for DUPLICATE), and cobalt (4.4 pg/L in MW-8, 1.4 pg/L in MW-9, and 13 in GP-10). The laboratory analytical
results indicated that the concentration of cobalt in MW-8 and MW-9 were below their respective laboratory

reporting limit. Constituents reported at concentrations below the reporting limit are flagged with a "J", indicating
an estimated concentration. It is important to note that the laboratory method detection limits (MDL) for vinyl
chloride and cobalt were 0.40 pg/L and 1.40 pg/L respectively which are greater than their respective 2L Standards
of 0.03 pg/L and 1.0 pg/L. Therefore, vinyl chloride and cobalt may have been present at concentrations above the
2L Standard but reported below the MDL.
5.2 Surface Water
The surface water samples were compared to the North Carolina Class C surface water standards as promulgated
in 15A NCAC 2B (213 Standards). The surface water sample results for the October 2022 sampling event are
summarized in Table S.
The inorganic constituents barium and vanadium were detected above their laboratory MDLs but below their 2B
Standards in the samples from the upstream (SW-1) and downstream (SW-2) surface water monitoring locations
during the October 2022 sampling event.
Two organic constituents analyzed (Acetone, and 2-Butanone (MEQ were detected at a concentration above the
laboratory MDL in the sample from the upstream (SW-1) surface water sampling location during the October 2022
sampling event. One organic constituents analyzed (1,4-dioxane) were detected at a concentration above the
laboratory MDL in the sample from the downstream (SW-2) surface water sampling location during the October
2022 sampling event. All detected constituent concentrations were reported with a "J" laboratory qualifier,
indicating that the value is an estimated concentration. It is important to note that the laboratory method
detection limits (MDL) for vinyl chloride was 0.40 pg/L which is greater than their respective 2B Standard of 0.025
pg/L. Therefore, vinyl chloride may have been present at concentrations above the 2B Standard but reported
below the MDL.
6.0 Quality Control Samples
Quality control samples are required by the WQMP to demonstrate consistency of the laboratory analytical
processes and field sampling methods.
During the October 2022 sampling event, in addition to the groundwater sample collected from monitor well
MW-8 (record sample), a blind duplicate sample was also collected from monitor well MW-8 (duplicate sample).
As shown on Table 5, similar analytes were reported for the record sample and the duplicate sample.
To assess the efficacy of the field equipment decontamination procedures, an equipment rinse sample was taken
by pumping laboratory supplied deionized water through new polyethylene tubing directly into laboratory
supplied containers using a peristaltic pump. The equipment blank sample was analyzed for the full Appendix I
analyte list. Two constituents (chlorodibromomethane and dichlorobromomethane) were detected above the
laboratory MDL, chlorodibromomethane was detected above the 2L Standard. A trip blank was also included in
the quality control samples. The trip blank consisted of water supplied from the laboratory in two 40 ml vials
which were kept unopened in the sample cooler throughout the sampling event and analyzed for Appendix I
VOCs. The results of the quality control sampling are presented with the analytical results in Appendix III of this
report.

7.0 Statistical Analysis
Previous monitoring reports submitted to the Section for this facility have included a statistical evaluation of
groundwater monitoring data. Statistical analysis was performed to determine whether a statistically significant
increase (SSI) above computed Upper Limits calculated from the upgradient background data set had occurred.
For this sampling event, no statistical analysis was performed on the data.
8.0 Summary
S&ME was contracted by Sorrell to provide groundwater and surface water monitoring services at Sorrell Landfill
located just off Smith Road (S.R. 1303) near Apex, North Carolina. Groundwater samples were collected from one
upgradient (background) well (MW-1 R), four shallow and one deep downgradient (compliance) wells (MW-5, MW-
6, MW-8, MW-9 and DW-1), and one off -site assessment well (GP-10). Surface water samples were collected from
the up -gradient and down -gradient surface water monitoring points (SW-1 and SW-2).
As shown on the potentiometric map (Figure 2), groundwater in the vicinity of the landfill is projected to flow
north-northwest toward an unnamed tributary of Middle Creek. It should be noted that static water levels
measured during the October 2022 sampling event indicate that MW-8 may be located hydraulically cross -
gradient of the landfill cell. In addition, the groundwater elevation in DW-1 was observed to be higher than the
groundwater elevation in MW-8 during the October 2022 sampling event. The difference in groundwater
elevations indicates that an upward gradient exists between the two water -bearing zones in the vicinity of these
two wells. These findings are consistent with historical data.
Groundwater and surface water samples were analyzed by ENCO Laboratories for constituents listed in Appendix I.
The sample from monitor well MW-8 and off -site assessment monitor well GP-10 were also analyzed for
constituents listed in Appendix Il. Laboratory analytical methods included EPA Method 6010D/6020B (metals),
Method 8260D (VOCs), Method 8270E (SVOCs), Method 7470A (Mercury), Method 9014 (cyanide) and Method SM
4500S2 D-2011 (sulfide).
8.1 Groundwater Results
From groundwater samples collected during the October 2022 sampling event, five constituents were detected at
concentrations greater than their respective 2L Standards: benzene (1.8 pg/L in MW-8 and 1.9 for DUPLICATE),
tetrachloroethene (1.8 pg/L in MW-8 and 1.9 pg/L for DUPLICATE), trichloroethene (22 pg/L in MW-8 and 24 pg/L
for DUPLICATE), vinyl chloride (2.9 pg/L in MW-8 and 3.4 pg/L for DUPLICATE), cobalt (4.4 pg/L in MW-8, 1.4 pg/L
in MW-9, and 13 pg/L in GP-10). All laboratory analytical results indicated that the concentrations of cobalt were
below their respective laboratory reporting limits. Constituents reported at concentrations below the reporting
limit are flagged with a "J", indicating an estimated concentration.
It is important to note that the laboratory method detection limits (MDL) for vinyl chloride and cobalt were 0.40
pg/L and 1.40 pg/L respectively which are greater than their respective 2L Standards of 0.03 pg/L and 1.0 pg/L.
Therefore, vinyl chloride and cobalt may have been present at concentrations above the 2L Standard but reported
below the MDL.

8.2 Surface Water Samples
From the surface water samples collected during the October 2022 sampling event, two organic constituents
analyzed, Acetone and 2-Butanone (MEK) were detected at a concentration above the laboratory MDL in the
sample collected from the downstream (SW-1) surface water sampling location during the October 2022 sampling
event. One organic constituent analyzed, 1,4-dioxane was detected at a concentration above the laboratory MDL
in the sample collected from the downstream (SW-2) surface water sampling location during the October 2022
sampling event. The detected constituent concentrations were reported with a "J" laboratory qualifier indicating
that the values are estimated concentrations.
The inorganic constituents barium and vanadium was detected above the MDL in the samples from the upstream
(SW-1) surface water monitoring location and the downstream (SW-2) surface water sample location during the
October 2022 monitoring event. No constituents were detected above their respective 2B Standards in the
sample collected from the upstream SW-1 or the downstream SW-2 location.
9.0 Recommendations
As required by North Carolina Solid Waste Management Rule .1634, these results should be forwarded to the
owner/operator of Sorrell Landfill for inclusion in the operating record and to the NCDEQ Division of Waste
Management for their review. In addition to the conclusions presented in previous chapters of this report, S&ME
provides the following recommendations:
Analytical data since 1999 have demonstrated that the use of low -flow sampling techniques has
successfully reduced reported inorganics in the samples to more accurate results. The inorganic
constituents that continue to be detected at concentrations greater than NC Water Quality standards
appear to represent naturally occurring concentrations in groundwater. Accordingly, it is recommended
that monitoring for inorganics continue to be limited to Appendix I inorganic compounds at the facility's
monitor wells (no cyanide or sulfide).
VOCs have been detected in samples collected from well MW-8 since the well was installed in 2001. The
consistent detection of VOCs at MW-8 indicates that a source, or sources, of VOCs may be present at, or
near, this well. Additional assessment of surrounding properties was conducted in October 2008 to
further evaluate the extent of the groundwater contamination near MW-8. VOCs were detected above
the 2L Standards in the off -site groundwater assessment monitor wells in October 2008 and subsequent
monitoring events. To monitor the off -site groundwater contamination, four off -site piezometers, GP-8,
GP-9, GP-10 and GP-10D, were sampled during the October 2020 sampling event. Of the VOCs detected
in compliance well MW-8, none were detected in the sample collected from piezometer GP-9 and GP-10D
in the October 2020 sampling event. Several of the VOCs detected in compliance well MW-8 were also
detected in off -site piezometers GP-8 and GP-10. An assessment of corrective measures and corrective
action should be performed to address the groundwater contamination near MW-8. Groundwater
monitoring at MW-8 should continue to be analyzed for Appendix II VOCs and sampling of the off -site
assessment wells in the vicinity of MW-8 (i.e., GP-8, GP-9 and /or GP-10) continue to be included as part
of the regular compliance monitoring, to monitor the extent, movement and concentration of off -site
groundwater contamination.

Surface water quality is monitored upstream and downstream in the vicinity of the landfill at sampling
locations SW-1 and SW-2, respectively. None of the Appendix I targeted compounds or metals exceeded
its respective 2B Standard. Samples from surface water sampling locations SW-1 and SW-2 should
continue to be monitored for the Appendix I organic and inorganic compounds required for detection
monitoring.
It is our understanding that the Wake County Department of Environmental Services, Water Quality
Division regularly samples the potable wells on the adjacent properties to the south of the landfill (Dye
and Herndon properties) as a precautionary measure to protect the users of these potable wells. S&ME
recommends the results of this sampling event be provided to Wake County for consideration in deciding
protective measures for the potable wells and their users.

Receipt
The samples were received on 11/2/2022 8:00 AM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.3°C
GC/MS VOA
Method 8260D: The laboratory control sample (LCS) for analytical batch 680-750117 recovered outside control limits for the following
analyte(s): Vinyl acetate. Vinyl acetate has been identified as a poor performing analyte when analyzed using this method; therefore,
re-extraction/re-analysis was not performed. These results have been reported and qualified.
Method 8260D: The RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for analytical batch
680-750117 recovered outside control limits for the following analytes: 1,1-Dichloroethene, Carbon disulfide, Carbon tetrachloride,
Chloromethane, Trichlorofluoromethane and Vinyl chloride.
Method 8260D: The following analyte(s) recovered outside control limits for the LCS associated with analytical batch 680-750117: Carbon
tetrachloride. This is not indicative of a systematic control problem because these were random marginal exceedances. Qualified results
have been reported.
Method 8260D: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with
analytical batch 680-750117.
Method 8260D: Trichlorofluoromethane is reported with an E flag in the batch QC because the top two points were dropped from the ICAL
The sample associated with the QC was non detect for Trichlorofluoromethane. The data has been qualified and reported. <(CCVIS
680-750117/4), (LCS 680-750117/5) and (LCSD 680-750117/6)
Method 8260D_SIM: The following sample was collected in a properly preserved vial; however, the pH of 6 was outside the required
criteria of <2 when verified by the laboratory. The sample was analyzed outside the 7-day holding time specified for unpreserved samples
but within the 14-day holding time specified for preserved samples: 9204-EQUIPMENT BLANK (680-224568-12).
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
GC/MS Semi VOA
Method 8270E: The laboratory control sample and/or the laboratory control sample duplicate (LCS/LCSD) for preparation batch
680-749092 and analytical batch 680-750610 recovered outside control limits for the following analyte(s): Pentachloronitrobenzene and
p-Phenylene diamine. Batch precision also exceeded control limits for alpha,alpha-Dimethyl phenethylamine and p-Phenylene diamine.
These analytes have been identified as poor performing analytes when analyzed using this method; therefore, re-extraction/re-analysis
was not performed. These results have been reported and qualified.
Method 8270E: The laboratory control sample (LCS) for preparation batch 680-749092 and analytical batch 680-750610 recovered outside
control limits for the following analyte: 1,4-Naphthoquinone. This analyte was biased high in the LCS and was not detected in the
associated samples; therefore, the data have been reported.
Method 8270E: Six surrogates are used for this analysis. The laboratory's SOP allows one acid and one base of these surrogates to be
outside acceptance criteria without performing re-extraction/re-analysis. The following sample contained an allowable number of
surrogate compounds outside limits: 9204-GP-10S (680-224568-9). These results have been reported and qualified.
Method 8270E: The RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for preparation batch
680-749092 and analytical batch 680-750610 recovered outside control limits for the following analytes: 4-Chloroaniline, 4-Nitrophenol,
N-Nitrosodimethylamine and Phenol.
Method 8270E: The laboratory control sample duplicate (LCSD) for preparation batch 680-749092 and analytical batch 680-750610

General Chemistry I
Method 90126: The matrix spike / matrix spike duplicate (MS/MSD) recoveries and precision for preparation batch 680-749687 and
analytical batch 680-749845 were outside control limits. Sample matrix interference and/or non -homogeneity are suspected because the
associated laboratory control sample / laboratory sample control duplicate (LCS/LCSD) precision was within acceptance limits.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
