S&ME Project No. 1054-07-251
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 April 25, 2019.
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 April 2019 monitoring event, one background well (MW-1 R), one deep and four shallow compliance
wells (DW-1, MW-5, MW-6, MW-8 and MW-9), one off -site assessment well (GP-9) and two surface water
sampling locations (SW-1 and SW-2) were sampled. Based on groundwater elevations measured during the April
2019 sampling event, the overall groundwater flow at the landfill is to the west-northwest at an average velocity of
35.51 feet per year (ft/yr). Deep well DW-1 was 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). In addition, the groundwater samples from monitor wells
MW-8 and GP-9 were also analyzed for the Appendix 11 List of Hazardous Inorganic and Organic Constituents
(Appendix 11) 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 groundwater samples collected in April 2019, six constituents were detected at concentrations greater than
their respective 2L Standards, or GWPSTs: benzene, tetrachloroethene, trichloroethene, vinyl chloride, cobalt, and
vanadium. Dichlorodifluoromethane is the only organic constituent on the Appendix II list that was detected
above the laboratory method detection limits (MDLs).
For surface water samples, the metals barium, vanadium, and zinc were detected above their MDLs in the sample
from the upstream (SW-1) surface water monitoring location. Barium was detected in the downstream (SW-2)

surface water sample location in April 2019. None of the detected metals were at concentrations that exceeded
its respective 2B Standard. The organic constituent 1,4-dioxane was detected at a concentration above its
respective 2B Standard from the surface water sample collected from the downstream (SW-2) location.
The frequency and number of metals detected at the site have declined since low -flow sampling procedures were
implemented in 1999. 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 plume in the area of 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 in the
area of 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
potable wells and their users.

April 2019 Semi -Annual Monitoring
Sorrell Landfill (DWM Permit No. 92-04)

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 April
25, 2019. 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 may be 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 requested, on behalf of the owners, 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 April
2019 sampling event at the facility, which included the sampling of one background well (MW-1 R), one deep and
four shallow compliance wells (DW-1, MW-5, MW-6, MW-8 and MW-9), one off -site assessment well (GP-9) 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 in regards to 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. Soils 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 metavolcanic 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.

S&ME Project No. 1054-07-251
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 metavolcanic 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 drilling activities, 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
August 29, 2019

S&ME Project No. 1054-07-251
groundwater measurements and groundwater elevation calculations for each of the monitor wells sampled during
the April 2019 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 wells
(MW-1 R, MW-4) and in the compliance wells (MW-5, MW 6, MW-7, MW-8 and MW-9) during the sampling event.
Depth to groundwater was also measured in the deep 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 thirteen groundwater piezometers (GP-7, GP-7D,GP-8, GP-9, GP-10, GP-10D, GP-11, GP-12, GP-12D,
GP-13, 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 north-northwest toward an unnamed
tributary of Middle Creek, which is consistent with previous groundwater 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 April 25, 2019 sampling event and by applying the following
equation (Driscoll, 1986):
i=h1-h2
L
Where:
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,
August 29, 2019

April 2019 Semi -Annual Monitoring

S&ME Project No. 1054-07-251
and MW-4, and MW-8, MW-5 and MW-6. The groundwater elevation in monitor well MW-4 was not measured
during the April 2019 sampling event, so it was not used to calculate the hydraulic gradient. Using MW-1 R/MW-9,
and MW-8, MW-5, and MW-6 the average hydraulic gradient is estimated to be 0.0281 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
Where:
v = Average linear groundwater flow velocity [feet per day (ft/day)]
K = Hydraulic conductivity (ft/day)
i = Flow gradient as a ratio (ft/ft),
n = Effective soil porosity (percent)
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 0.0281 ft/ft, calculated from the three point calculation
described above; and an effective porosity of 20%. Groundwater flow velocities calculated during the April 2019
sampling event ranged from 27.82 feet per year (ft/yr) between monitor wells MW-8 and MW-5 to 45.34 ft/yr
between monitor wells MW-1 R and MW-9. The average groundwater flow velocity for the site was approximately
38.72 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 April 2019 sampling event indicate that MW-8 may be located
hydraulically cross -gradient of the landfill cell.
August 29, 2019

April 2019 Semi -Annual Monitoring
Sorrell Landfill (DWM Permit No. 92-04)
Apex, Wake County, North Carolina
S&ME Project No. 1054-07-251
DW-1 is the only 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 3.82 feet higher than the
groundwater elevation in MW-8 during the April 2019 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 April 2018 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 April 25, 2019. One shallow off -site groundwater
assessment well (GP-9) was also sampled during the April 2019 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 150 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
three 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:

S&ME Project No. 1054-07-251
• MW-1 R, MW-5, MW-6, MW-8, 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-9 were analyzed for constituents listed in Appendix II (40 CFR 258).
Laboratory analytical methods for Appendix I constituents included EPA Method 6010C/6020A (metals) and
Method 8260B volatile organic compounds (VOCs).
Laboratory analytical methods for Appendix II constituents included the Appendix I constituent list, plus Method
8270D (SVOCs), Method 7470A (mercury), Method 9014 (cyanide) and SM18 4500-5 D (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 150 milliliters per minute until the
turbidity is 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 April 2019 sampling event, the specific conductance measured in the background well (MW-1 R) was
0.040 milliSiemens per centimeter (mS/cm). Measurements in the four shallow compliance wells (MW-5, MW-6,
MW-8, and MW-9) ranged from 0.102 mS/cm (MW-9) to 0.179 mS/cm (MW-5). The specific conductance
measured in the off -site monitoring well (GP-9) was recorded as 0.048 mS/cm. The specific conductance
measured in the deep compliance well (DW-1) was recorded as 0.108 mS/cm. The highest groundwater
conductivity value (0.179 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.

S&ME Project No. 1054-07-251
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 4.9. The pH measured in the four shallow compliance wells
ranged from 5.0 (MW-8) to 6.3 (MW-5). The pH values are within the range that would be expected for shallow
groundwater conditions in the Eastern Piedmont region. The pH in the off -site monitoring well (GP-9) was
recorded as 5.3. The pH measured in the deep compliance well (DW-1) was recorded as 6.2.
4.3 Temperature
Groundwater temperature collected from the background well was 17.1 °C (MW-1 R). Groundwater temperatures
recorded from samples collected from four shallow compliance wells ranged from 15.0 °C (MW-6) to 18.7 °C
(MW-8). Temperature measured from the deep compliance well (DW-1) was 18.2 IC. Temperature measured
from the off -site assessment well (GP-9) was recorded as 17.7 IC. Where the aquifer is in close proximity to 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 101 C increase in temperature between 5 °C and 25 IC. 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 April 2019 sampling event, the target value of 10 NTUs was not achieved in monitor wells
MW-1 R and MW-6. Groundwater turbidity recorded just prior to sample collection in the four shallow compliance
wells ranged from 0.81 NTUs (MW-8) to 20.6 NTUs (MW-6). The turbidity level measured in the deep compliance
well (DW-1) was recorded as 0.02 NTUs. The turbidity level measured in the off -site assessment well (GP-9) was
recorded as 5.91 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 April 25, 2019. 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-9 were additionally analyzed for Appendix II SVOCs,
mercury, cyanide and sulfide. Laboratory analytical methods included EPA Method 6010C/6020A (metals),
Method 8260B (VOCs), Method 8270D (SVOCs), Method 7074A (mercury), Method 9014 (cyanide), and SM18
4500-5 D (sulfide). The analytical results for the groundwater and surface water samples collected and analyzed in
April 2019 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 North Carolina groundwater standards as presented in
15A North Carolina Administrative Code, Subchapter 2L (15A NCAC 2L), hereafter referred to as the 2L Standards
and to the Solid Waste Groundwater Protection Standards (GWPST) established in accordance with the Solid
Waste Rules Section .1634(h). The analytical results for the April 2019 sampling event are summarized on Table 5.
For the April 2019 sampling event, six constituents were detected at concentrations greater than their respective
2L Standards, or GWPSTs: benzene (2.1 µg/L in MW-8), tetrachloroethene (42 µg/L in MW-8), trichloroethene (8.9
µg/L in MW-8), vinyl chloride (4.6 pg/L in MW-8), cobalt (3.36 pg/L at MW-8 and 5.05 µg/L at MW-9), and
vanadium (2.05 pg/L in MW-1 R, 3.94 pg/L in MW-5, and 8.81 pg/L in MW-6). The laboratory analytical results
indicated that the concentrations of cobalt (in MW-8 and MW-9); and vanadium (in MW-1 R, MW-5, and MW-6);
were below their respective laboratory reporting limits. Constituents reported at concentrations below the
reporting limit are flagged with a "J" and are considered to be an estimate. It is important to note that the
laboratory method detection limit (MDL) for vinyl chloride is 0.32 pg/L which is greater than the 2L Standard of 0.3
pg/L. Therefore, vinyl chloride 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 April 2019 sampling event are
summarized in Table S.
Of the organic constituents analyzed, only 1,4-dioxane was detected at a concentration above the respective
MDLs from the surface water samples collected during the April 2019 sampling event. The inorganic constituents,
barium, vanadium, and zinc were detected above their MDLs in the sample from the upstream (SW-1) surface
water monitoring location during the April 2019 monitoring event. Barium was detected in the downstream (SW-
2) surface water sample location in April 2019. With the exception of 1,4-dioxane (SW-2), no constituents were
detected above their respective 2B Standards in the sample collected from the upstream SW-1 or the downstream
SW-2 location. However, detected constituent concentrations of vanadium and zinc for the sample from SW-1

location were reported with a "Y' laboratory qualifier indicating that the values are estimated concentrations below
the lowest calibration point.
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 April 2019 sampling event, in addition to the groundwater sample collected from monitor well MW-1 R
identified as MW-1 R on the chain -of -custody (record sample), a blind duplicate sample was also collected from
monitor well MW-1 R (duplicate sample). As shown on Table 5, similar analytes were reported for the record
sample and the duplicate sample.
Additionally, to assess the efficacy of the field equipment decontamination procedures, an equipment rinse
sample was taken by dipping the probe of the decontaminated water level meter into a laboratory supplied bottle
of deionized water. The equipment blank sample was analyzed for the full Appendix I analyte list. No
constituents were detected above the laboratory's method detection limit (MDL) with the exception of barium at
an estimated concentration of 1.36 pg/L. 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 or not a statistically
significant increase (SSI) above statistically 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-9). Surface water samples were collected from
the up -gradient and down -gradient surface water monitoring points (SW-1 and SW-2).
The depth to the groundwater was measured in each monitor well and landfill methane well located at the site.
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 April 2019 sampling event indicate that MW-8 may be located hydraulically upgradient 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 April 2019 sampling event. This difference in groundwater elevations indicates that

April 2019 Semi -Annual Monitoring
Sorrell Landfill (DWM Permit No. 92-04)
Apex, Wake County, North Carolina I
S&ME Project No. 1054-07-251
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-9 were also analyzed for
constituents listed in Appendix II. Laboratory analytical methods included EPA Method 6010C/6020A (metals),
Method 8260B (VOCs), Method 8270D (SVOCs), Method 7470A (Mercury), and Method 9014 (cyanide).
8.1 Groundwater Results
From groundwater samples collected during the April 2019 sampling event, six constituents were detected at
concentrations greater than their respective 2L Standards, or GWPSTs: benzene (2.1 µg/L in MW-8),
tetrachloroethene (42 µg/L in MW-8), trichloroethene (8.9 µg/L in MW-8), vinyl chloride (4.6 pg/L in MW-8),
cobalt (3.36 pg/L at MW-8 and 5.05 µg/L at MW-9), and vanadium (2.05 pg/L in MW-1 R, 3.94 pg/L in MW-5, and
8.81 pg/L in MW-6).
It is important to note that the laboratory method detection limit (MDL) for vinyl chloride is 0.32 pg/L which is
greater than the 2L Standard of 0.03 pg/L. Therefore, vinyl chloride may have been present at concentrations
above the 2L Standard but reported below the MDL.
8.2 Surface Water Samples
The inorganic constituents barium, vanadium, and zinc were detected above their MDLs in the sample from the
upstream (SW-1) surface water monitoring location during the April 2019 monitoring event. Barium was detected
in the downstream (SW-2) surface water sample location in April 2019. Detected constituent concentrations of
vanadium and zinc for the sample from SW-1 location were reported with a "Y' laboratory qualifier indicating that
the values are estimated concentrations below the lowest calibration point. None of the listed metals exceed their
applicable 213 Standard.
Organic constituents in surface water samples collected during the April 2019 sampling event were not detected
at concentrations above their MDLs with the exception of 1,4-dioxane (SW-2). Detected constituent
concentrations in the upstream sample were similar to, or less than, concentrations in the downstream sample.
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. Accordingly, it is
August 29, 2019 13

April 2019 Semi -Annual Monitoring
Sorrell Landfill (DWM Permit No. 92-04)
Apex, Wake County, North Carolina I
S&ME Project No. 1054-07-251
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 plume in the area of 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, off -site piezometer, GP-9, was
sampled during the April 2019 sampling event. Of the VOCs detected in nearby compliance well MW-8,
none were detected in the sample collected from piezometer GP-9 during the April 2019 sampling event.
An assessment of corrective measures and corrective action should be performed to address the
groundwater contamination in the area of 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.

Dear Sam Watts,
Enclosed is a copy of your laboratory report for test samples received by our laboratory on
Friday, April 26, 2019.
Unless otherwise noted in an attached project narrative, all samples were received in
acceptable condition and processed in accordance with the referenced methods/procedures.
Results for these procedures apply only to the samples as submitted.
The analytical results contained in this report are in compliance with NELAC standards, except
as noted in the project narrative if applicable. This report shall not be reproduced except in
full, without the written approval of the Laboratory.
This report contains only those analyses performed by Environmental Conservation
Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from
outside organizations will be reported under separate cover.
If you have any questions or require further information, please do not hesitate to contact me.

PROJECT NARRATIVE
Client: S&ME, Inc. (SM001)
Project: Sorrell Landfill - Semi -Annual
Lab ID: CC06058
(� �Eo
www.encolabs.com
Overview
Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods
referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in
the QC Remarks section below.
Quality Control Samples
The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on an acceptable
LCS recovery (QM-07).
The associated LCS exhibited high bias; since the result is ND, there is no impact (QL-02).
The post-digestionb spike did not meet method requirements due to confirmed matrix effects (QM-08).
Quality Control Remarks
The associated CCV standard exhibited high bias; since the result is ND, there is no impact (QV-01).
The associated CCV standard exhibited low bias; the reported result should be considered a minimum estimate (QV-02).
The method blank contains analyte at a concentration above the MDL and/or greater than one-half of the MRL. The analyte
was not detected in the sample (QB-02).
Other Comments
The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any
exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of
the report.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.
QB-02 The method blank contains analyte at a concentration above the MDL and/or greater than one-half the
MRL. The analyte was not detected in the sample.
QL-02 The associated laboratory control sample exhibited high bias; since the result is ND, there is no impact.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-08 Post -digestion spike did not meet method requirements due to confirmed matrix effects (dilution test).
QM-10 LCS/LCSD were analyzed in place of MS/MSD.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.
QV-02 The associated continuing calibration verification standard exhibited low bias; the reported result should
be considered to be a minimum estimate.
