 EXECUTIVE SUMMARY

S&ME, Inc. (S&ME) was 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 November 3, 2017.
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. Services
conducted by S&ME for the November 2017 sampling event were performed in general accordance with S&ME
Proposal No. P4258-07V, dated April 25, 2007 and the S&ME’s memorandum Cost Estimate for 2017 Semi-Annual
Groundwater and Surface Water Sampling Events, dated March 16, 2017.

During the November 2017 monitoring event, one background well (MW-1R), one deep and four shallow
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
November 2017 sampling event, the overall groundwater flow at the landfill is to the east-northeast at an average
velocity of 32.85 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. However, 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 assumption.

Groundwater and surface water samples were analyzed for constituents listed in 40 CFR 258, Appendix I
Constituents for Detection Monitoring (Appendix I). In addition, the groundwater samples from monitor wells
MW-8 and GP-10 were also 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, NCDEQ Solid Waste Section Limits (SWSLs) 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 (2B Standards).

From groundwater samples collected during the November 2017 sampling event, eight constituents were
detected at concentrations greater than their respective 2L Standards or SWSL Standards: 1,2-dichloropropane,
benzene, tetrachloroethene, trichloroethene, vinyl chloride, cadmium, cobalt, and vanadium.

During the November 2017 monitoring event, none of the Appendix II organic constituents were detected above
the laboratory method detection limits (MDLs). The inorganic constituents barium, cobalt, vanadium, and zinc
were detected above their MDLs in the sample from the upstream (SW-1) surface water monitoring location.
Barium and copper were detected in the downstream (SW-2) surface water sample. Cobalt, at SW-1, was the only
organic constituent detected at a concentration above the respective surface water quality standards (2B
Standards), at 7.92 J.

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 (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 off-site groundwater contamination.

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.

1.0 Introduction
1.1 Background
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
November 3, 2017. 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 groundwater 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-1R 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 I). 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 II) 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), 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 upgradient 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-
1R), 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
November 2017 sampling event at the facility which included the sampling of one background well (MW-1R), one
deep and four shallow 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 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 (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.

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 feet 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 feet bgs and approximately 45 feet bgs in an upgradient well
(MW-1R). 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 34 feet bgs on the eastern (upgradient) side of the landfill at
MW-1R.
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 the closest 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 shows the depth to groundwater

measurements and groundwater elevation calculations for each of the monitor wells sampled during the
November 2017 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-1R, 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 is believed to monitor 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 monitor wells (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 that
were used to assess groundwater contamination 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 November 3, 2017 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 from two three point solutions using well sets MW-1R, MW-9, and MW-4, and MW-

8, MW-5 and MW-6 is estimated to be 0.026 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
n

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 0.026 ft/ft, calculated from the three point calculation
described above; and an effective porosity of 20%. Groundwater flow velocities calculated during the November
2017 sampling event ranged from 26.82 feet per year (ft/yr) between monitor wells MW-8 and MW-5 to 40.24
ft/yr between monitor wells MW-1R and MW-9. Calculations performed using the equation and input values
above estimate the average groundwater flow velocity for the site was approximately 32.85 ft/yr. 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 November 2017 sampling event indicate that MW-8 may be located
hydraulically upgradient of the landfill cell.

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 3.20 feet higher than the
groundwater elevation in MW-8 during the November 2017 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 November 2017 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-1R), four shallow and one deep
compliance wells (MW-5, MW-6, MW-8, MW-9 and DW-1) on November 3, 2017. One shallow off-site
groundwater assessment well (GP-10) was also sampled during the November 2017 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 two minutes apart. Monitor well MW-1R 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 analysis according to the following:

 MW-1R, MW-5, MW-6, MW-8, MW-9, DW-1, SW-1, and SW-2 were analyzed for constituents listed in
Appendix I (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 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-S 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 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. Conductivity is therefore 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 November 2017 sampling event, the specific conductance measured in the background well (MW-1R)
was 0.025 milliSiemens per centimeter (mS/cm). Measurements in the four shallow compliance wells (MW-5, MW-
6, MW-8, and MW-9) ranged from 0.043 mS/cm (MW-9) to 0.114 mS/cm (MW-5). The specific conductance was
not measured in the off-site monitoring well (GP-10) due to a small water column. The specific conductance
measured in the deep compliance well (DW-1) was recorded as 0.070 mS/cm. The highest groundwater
conductivity value (0.0.114 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.

Sorrell Landfill (DWM Permit No. 92-04)
Apex, Wake County, North Carolina
S&ME Project No. 1054-07-251

The pH of the groundwater in the landfill wells was measured just prior to sample collection. The pH reading in
the background well (MW-1R) was measured as 4.99. The pH measured in the four shallow compliance wells
ranged from 4.70 (MW-8) to 6.34 (MW-5). The pH values are within the range that would be expected for shallow
groundwater conditions in the Eastern Piedmont region. The pH was not measured in the off-site monitoring well
(GP-10) due to a small water column. The pH measured in the deep compliance well (DW-1) was recorded as
6.25.
4.3 Temperature
Groundwater temperature collected from the background well was 16.21º C (MW-1R). Groundwater temperatures
recorded from samples collected from four shallow compliance wells ranged from 16.16º C (MW-9) to 20.70º C
(MW-8). Temperature measured from the deep compliance well (DW-1) was 19.30º C. Temperature was not
measured from the off-site assessment well (GP-10) due to a small water column. 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 10º C increase in temperature between 5º C and 25º 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-1R and MW-6 during the initial baseline sampling event were turbid, it was suggested that suspended soil
particles present in the groundwater could have contributed to elevated concentrations of metals reported by the
laboratory. Therefore a turbidity value of 10 NTUs was established as a goal to achieve while purging and prior to
collection of samples. During the November 2017 sampling event, the target value of 10 NTUs was not achieved
in monitor well MW-1R, in monitor well MW-6, and in the off-site assessment well GP-10. Groundwater turbidity
recorded just prior to sample collection in the four shallow compliance wells ranged from 0.9 NTUs (MW-8) to
30.8 NTUs (MW-6). The turbidity level measured in the deep compliance well (DW-1) was documented out of
range. The turbidity level measured in the off-site assessment well (GP-10) was recorded as 12.4 NTUs.
5.0 Analytical Results

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 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-S D (sulfide). The analytical results for the groundwater and surface water samples collected and analyzed in
November 2017 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 the Solid Waste Groundwater Protection Standards (GWPST) established in accordance with the Solid Waste
Rules Section .1634(h). The analytical results for the November 2017 sampling event are summarized on Table 5.

From groundwater samples collected during the November 2017 sampling event, nine constituents were detected
at or above the reporting limits established by the Solid Waste Section (SWSLs). The SWSL has little regulatory
significance, except that it is a minimum reporting limit. For several constituents, the SWSL is greater than the
corresponding North Carolina Groundwater Protection Standard.

For the November 2017 sampling event, eight constituents were detected at concentrations greater than their
respective 2L Standards, or GWPSTs: 1,2-dichloropropane (1.3 µg/L at MW-8), benzene (6.5 µg/L at MW-8),
tetrachloroethene (34 µg/L at MW-8), trichloroethene (17 µg/L at MW-8), vinyl chloride (5 µg/L in MW-8),
cadmium (3.23 µg/L at GP-10), cobalt (1.3 µg/L at MW-6, 4.41 at MW-8, 2.54 µg/L at MW-9, and 7.81 at GP-10),
and vanadium (8.18 µg/L in MW-1R, 3.53 µg/L in MW-5, and 13.8 µg/L in MW-6). The laboratory analytical results
indicated that the concentrations of cobalt reported from MW-6, MW-8, MW-9, and GP-10; and vanadium
reported from MW-1R and MW-5; 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 µg/L which is greater
than the 2L Standard of 0.03 µg/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 (2B Standards). The surface water sample results for the November 2017 sampling event are
summarized in Table 5.

Of the organic constituents analyzed, only cobalt (7.92 µg/L in at SW-1), was detected at a concentration above
the respective MDLs from the surface water samples collected during the November 2017 sampling event.
The inorganic constituents barium, cobalt, vanadium, and zinc were detected above their MDLs in the sample from
the upstream (SW-1) surface water monitoring location during the November 2017 monitoring event. Barium and
copper were detected in the downstream (SW-2) surface water sample location in November 2017. The inorganic
constituent cobalt was detected above the respective 2B Standard in the sample collected from the upstream SW-

1 location. No inorganic constituents were detected above their respective 2B Standards in the sample collected
from the downstream SW-2 location. However, the vanadium concentrations in the sample collected from the
upstream SW-1 and the copper concentrations in the sample collected from the downstream SW-2 location were
reported with a “J” 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 November 2017 sampling event, in addition to the groundwater sample collected from monitor well
DW-1 and identified as DW-1 on the chain-of-custody (record sample), a blind duplicate sample was also
collected from monitor well DW-1 (duplicate sample). As shown on Table 5, similar analytes were detected in 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. The inorganic
constituents of beryllium and copper were reported with a “J” laboratory qualifier indicating that the value is an
estimated concentrations below the lowest calibration point. No other constituents were detected above the
laboratory’s method detection limit (MDL). 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-1R), 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).

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 November 2017 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 November 2017 sampling event. This 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 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 November 2017 sampling event, eight constituents were
detected at concentrations greater than their respective 2L Standards, or GWPSTs: 1,2-dichloropropane (1.3 µg/L
at MW-8), benzene (6.5 µg/L at MW-8), tetrachloroethene (34 µg/L at MW-8), trichloroethene (17 µg/L at MW-8),
vinyl chloride (5 µg/L in MW-8), cadmium (3.23 µg/L at GP-10), cobalt (1.3 µg/L at MW-6, 4.41 at MW-8, 2.54 µg/L
at MW-9, and 7.81 at GP-10), and vanadium (8.18 µg/L in MW-1R, 3.53 µg/L in MW-5, and 13.8 µg/L in MW-6).
The detected analytes from the November 2017 sampling event are summarized on Table 5.

It is important to note that the laboratory method detection limit (MDL) for vinyl chloride is 0.32 µg/L which is
greater than the 2L Standard of 0.03 µg/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, cobalt, vanadium and zinc, were detected above their MDLs in the sample from
the upstream (SW-1) surface water monitoring location during the November 2017 monitoring event. Barium and
copper were detected in the downstream (SW-2) surface water sample location in November 2017. All inorganic
constituents detected in samples from SW-1 and SW-2 were reported with a “J” laboratory qualifier indicating that
the values are estimated concentrations below the lowest calibration point. Organic constituents in surface water
samples collected during the November 2017 sampling event were detected at concentrations below their
respective 2B Standards. Detected constituent concentrations in the downstream sample were similar to, or less
than, concentrations in the upstream 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
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 assessment monitor well
GP-10 was sampled during the November 2017 sampling event. Of the VOCs detected in nearby
compliance well MW-8, only tetrachloroethene (0.46 µg/L) was detected in off-site assessment monitor
well GP-10 during the November 2017 sampling event. However, this constituent was reported with a “J”
laboratory qualifier indicating that the value is an estimated concentration below the lowest calibration
point. 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 be analyzed for Appendix II VOCs and sampling of the off-site
assessment wells in the vicinity of MW-8 (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. Laboratory analysis of surface water quality do not indicate any
impact from the landfill to surface water. 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.

FLAGS/NOTES AND DEFINITIONS
The sample was analyzed at dilution.
The analyte was detected in the associated method blank.
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.
The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
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: Practical Quantitation Limit.PQL
The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
QM-07
Post-digestion spike did not meet method requirements due to confirmed matrix effects
(dilution test).
QM-08
Precision between duplicate matrix spikes of the same sample was outside acceptance limits.QM-11
The associated continuing calibration verification standard exhibited high bias; since the result is
ND, there is no impact.
QV-01
The associated continuing calibration verification standard exhibited low bias; the reported
result should be considered to be a minimum estimate.
