Compounds Detected At or Above Regulatory Standards during the July 2021 Sampling Event
(1/13-1/14/2021) - Southern Unit of the Pitt County Municipal Solid Waste Landfill (Permit #74-01)
Preliminary analysis of cause and significance of concentrations detected at or above
groundwater or surface water standards:
1,4-Dioxane, benezene, and barium were detected at concentrations exceeding the 15A NCAC 02L
groundwater standard in multiple wells. However, these constituents were not detected at
concentrations above state standards in groundwater samples collected from just below the
southern property ditch, or in downgradient surface -water samples. These results suggest that
these 1,4-dioxane, benzene, and concentrations in excess of naturally occurring barium are not
migrating off -site at this time. Further, neither 1,4-dioxane nor benzene were detected in the
sample collected from the deep monitoring well located down -gradient of the Southern Landfill Unit
(P20D). Barium, which is a naturally occurring metal, was detected in this well, but the
concentration (24.0 pg/L) was well below the NCAC 02L standard and below concentrations
detected in upgradient, off -site monitoring wells. The absence of these target compounds
suggests that contaminants have not migrated out of the Surficial/Yorktown Aquifer at the site.
The detection of 1,4-dioxane and other contaminants in well P29, which is located between the
Northern and Southern Landfill Units, indicates that the Northern Unit is likely also a source for
these contaminants. Pitt County recently completed substantial cap and stormwater repairs and
upgrades at the Southern Unit. These repairs were designed to limit the infiltration of rainwater
into the Southern mound and reduce leachate volume and concentrations.
Vinyl chloride and lead were also detected above the 15A NCAC 02L standards at individual wells
surrounding the Southern Unit. The completed cap and stormwater upgrades are expected to
reduce the concentrations of all contaminants in groundwater downgradient of the Southern Unit.
Thus, these parameters are currently being addressed through the remedial actions and pilot
study.

1.0 INTRODUCTION
The inactive Pitt County Solid Waste Municipal Landfill (Facility Permit #74-01, Figure 1) is
comprised of a Northern Unit that closed in 1990 and a Southern Unit that reached capacity and
closed in 1995. Based on its closure date, the Southern Unit is subject to the September 1993
rules for municipal solid waste landfills (15A NCAC 13B .1600). The Northern Unit, on the other
hand, is subject to the conditions of the solid waste permit and 15A NCAC 13B .0600.
Pitt County (the County) is currently working to address 1,4-dioxane and benzene groundwater
contamination at the Southern Unit, which lies adjacent to, and south of, the Northern Unit
(Figure 1). Groundwater contamination at the facility is believed to be related to the
degradation of the low -permeability, clay caps that cover each unit. Over time, erosion of the
caps, as well as cracking due to heating/cooling, desiccation, and/or subsidence due to
decomposition of fill material, increases the permeability of these barriers and allows infiltration
of water that can leach contaminants downward into the underlying groundwater.
On November 4, 2020, the County began construction on an extensive cap and a stormwater
system repair and upgrade project at the Southern Unit as part of an approved pilot study for
corrective action (Appendix A). These improvements are designed to greatly reduce the
infiltration of water through the cap in order to protect the groundwater from further
contamination via leaching from landfill waste. The County recently completed construction on
this $1.065 million project in June of 2021. The County continues to monitor groundwater and
surface water at the Southern Unit on a semi-annual schedule. This report presents the results
of the July 2021 semi-annual monitoring event, documents recent groundwater monitoring well
rehabilitation activities, and provides an update of the ongoing pilot study at the Southern Unit
of the Pitt County Landfill.
1.1 Site Background
The Pitt County Landfill occupies approximately 156 acres along Allen Road west of the city of
Greenville, NC (Figure 1). The landfill is comprised of two distinct units, the Northern Unit and
the Southern Unit. An east -west trending railroad (Norfolk Southern Railroad) separates the
Northern and Southern Units. The Pitt County landfill units are unlined, and leachate is not
collected. The Northern Unit received waste from 1974 until 1990, and the Southern Unit
received waste from 1991 until 1995. Due to the closure dates, only the Southern Unit is
subject to the September 1993 rules for municipal solid waste landfills (15A NCAC 13B .1600).
Pitt County monitors the Northern Unit in accordance with the conditions of the solid waste
permit and 15A NCAC 13B .0510.
1.2 Physical Setting and Hydrogeology
The Pitt County Landfill lies in the central portion of the Coastal Plain Physiographic Province of
North Carolina, where Cretaceous to Recent age Coastal Plain sedimentary formations overlie
Mesozoic and older basement bedrock (Horton and Zullo, 1991). Coastal Plain sediments and

July 2021 Semiannual Water Quality Monitoring Report
Southern Portion of the Pitt County Solid Waste Municipal Landfill
December 6, 2021
Page 2 of 13
sedimentary rocks have significant variations in permeability and water -producing capabilities.
High -permeability strata that readily produce usable quantities of water are aquifers, and low -
permeability sediments that restrict the movement of groundwater, either into or out of
aquifers, are confining beds. Coastal Plain aquifers typically use the predominant geologic
formation name that is associated with the aquifer. The two uppermost aquifers at the Pitt
County Landfill are: the unconfined Surficial/Yorktown Aquifer and the confined Peedee Aquifer.
The Surficial/Yorktown Aquifer is locally composed of fossiliferous clays and sands. The clays
within the unit tend to serve as confining layers and restrict recharge to underlying aquifers
(GMA and McGill, 2001). The Peedee Aquifer consists of unconsolidated sands and sandstones
of the of Late Cretaceous age Peedee Formation (Winner & Coble, 1996). In the western half
of Pitt County, the Peedee Aquifer lies directly beneath the Surficial/Yorktown Aquifer, and the
elevation of the top of the Peedee Aquifer is above sea level (GMA and McGill, 2001).
A detailed description of the local site hydrogeology is provided in the Water Quality Monitoring
Plan for the Southern Unit (GMA, 1994). In general, a sandy clay extends from the original land
surface beneath the landfill to depths varying from 6 to 13 feet. A portion of this clay may have
been excavated from areas adjacent to the Southern Unit mound and used as part of the clay
cap for the mound. Coarser, more permeable sediments (silty fine sand, clayey sand, and very
clayey sand) typically exist at depths of 10 to 16 feet. Underlying these more permeable
sediments, at a depth of approximately 16 feet below the original land surface, is a thin,
discontinuous, dark gray clay that ranges from 0.5 to 3.0 feet in thickness, with an average
thickness of 1 foot. This clay layer exists at an elevation of approximately 66 feet above mean
sea level and has previously been referred to as the "66-foot clay" (GMA, 1994). Below this
clay layer lie silty, fine sands. During the installation of deep monitoring well P20D, GMA
observed a silty, clay layer from approximately 45 to 48 feet below the land surface. Below this
clay layer, GMA observed a fine, phosphatic sand. GMA believes the deepest on -site monitoring
wells (e.g. MW1R, MW3, and P20D) may penetrate the top of the Peedee Aquifer, which is
estimated to be about 25 feet thick at the location of the landfill (GMA and McGill, 2001). We
provide a general summary of the stratigraphy below.

1.3 Contaminants of Concern and Site Regulatory Status
The Southern Unit of the Pitt County Landfill is currently under assessment for low-level
exceedances of the NC Groundwater Quality Standard (NCAC 02L) for benzene. The County
first confirmed a slight exceedance of the NCAC 02L groundwater standard for benzene in
groundwater samples collected from the landfill's monitoring well network in 2017. Since that
time and following approval from the North Carolina Department of Environmental Quality
(NCDEQ), Division of Waste Management (DWM), Solid Waste Section (SWS), the County has
collected groundwater samples from just beneath the southern ditch to monitor the extent of
benzene contamination at the facility. This ditch serves as the groundwater discharge location
for the Surficial Aquifer at the Southern Unit. To date, the County has not detected benzene in
exceedance of the NCAC 02L standard in these samples, which suggests that benzene
contamination above the NCAC 02L groundwater standard does not extend off the facility
property.
Pitt County is also currently assessing the Southern Landfill Unit for exceedances of the NCAC
02L standard for 1,4-dioxane. In May 2018, the NCDEQ DWM SWS directed all North Carolina
landfills to begin testing for 1,4-dioxane as part of their routine groundwater monitoring. 1,4-
Dioxane is used primarily as a chlorinated solvent stabilizer, but it can also be found in paint
strippers, varnishes, waxes, and a variety of consumer products (US EPA, 2014). 1,4-Dioxane is
fully miscible in water, and it migrates readily with groundwater. This compound is short-lived
in the atmosphere, but it does not volatilize rapidly from water.
1,4-Dioxane was detected at the landfill in July 2018, and the County immediately and
voluntarily chose to perform an updated potential receptor investigation to determine if any
water -supply wells might be at risk. Pitt County opted to conduct the potential receptor survey
as a proactive measure in the interest of public health. The updated potential receptor survey,
conducted by Groundwater Management Associates (GMA) in September 2018, did not identify
any wells being used as a drinking water source within 2,000 feet of the facility (GMA, 2018).
Exceedances of the NCAC 02L groundwater standard for 1,4-dioxane were confirmed at the
Southern Unit of the Pitt County Landfill in January 2019. GMA suspects that the detection of
1,4-dioxane in monitoring wells adjacent to the Southern Landfill Unit relates to degradation of
the integrity of one or both landfill caps and the stormwater drainage systems designed to
quickly shunt surface water off the landfill mounds. Pitt County emplaced the clay caps above
the Landfill in the mid-1990s. Over time, erosion of the cap, as well as cracking due to
heating/cooling, desiccation, and/or subsidence due to decomposition of fill material, can
increase the permeability of this type of barrier. Cap degradation may allow infiltration of water
that can leach contaminants downward into the underlying groundwater. Eliminating infiltration
of water through the cap, and ensuring that the stormwater conveyance system operates as

Southern Portion of the Pitt County Solid Waste Municipal Landfill
December 6, 2021
Page 4 of 13
designed, are primary goals for reducing, or eliminating, the release of additional contaminants
into the groundwater.
GMA, on behalf of the County, submitted a proposal to the SWS on June 21, 2019 to further
assess and address 1,4-dioxane contamination at the landfill. Specifically, we proposed to:
1) Delineate the vertical and horizontal extents of 1,4-dioxane by installing two additional
groundwater monitoring wells (one Type II monitoring well located between the two landfill
units and one double -cased, deep Type III monitoring well south of the Southern Mound)
and six surface water staff gauges.
2) Conduct a pilot study to document, and establish the effectiveness of, cap upgrades and
repairs to limit the infiltration of rainwater into the soil cap, and to evaluate if the repairs
have reduced leachate volumes and contaminant concentrations. During the pilot study,
the County proposed to:
a) conduct geophysical testing of the Southern Unit to evaluate landfill cap integrity,
b) repair any areas of concern identified by the geophysical testing,
c) inspect surface water drainage structures on the mound to ensure that they are
operating as designed, and then
d) repeat geophysical testing after cap repairs are made to document the results of the
cap repairs.
3) Install two in -stream piezometers approximately 1.5 feet below the ditch bottom at the
locations of the currently collected porewater samples. The in -stream piezometers will be
used to collect representative groundwater samples, measure groundwater levels, and
determine any discharge relationships at repeatable locations just below the stream bed.
The NCDEQ-SWS approved the proposed activities on June 26, 2019 (Appendix A), and the
County immediately began to implement the pilot study. We provide an update regarding the
status of the approved activities in Section 2.0 below.
2.0 1,4-DIOXANE ASSESSMENT AND PILOT STUDY UPDATE
North Carolina Administrative Code 15A NCAC 13B .1634 requires the County to characterize
the nature and extent of any release. The County began assessing the horizontal extent of 1,4-
dioxane during the January 2019 monitoring event by voluntarily sampling additional wells that
were no longer part of the groundwater monitoring program.
In June of 2019, the County installed the two monitoring wells and the six surface water staff
gauges described in GMA's Pilot Study proposal. The single -cased (Type -II) monitoring well
was installed between the Northern and Southern mounds, just north of well P16R (Figure 1).
This well, designated as well P29, is hydrologically separated from well P16R by two drainage

Southern Portion of the Pitt County Solid Waste Municipal Landfill
December 6, 2021
Page 5 of 13
ditches along the railroad, and the well is screened from 7 to 12 feet below the land surface.
The 60-foot-deep, double -cased (telescoping, Type -III) groundwater monitoring well was
installed on the south side of the Southern Unit, just off the toe of the slope of the Southern
Mound (Figure 1). This well, designated as well P20D, allowed the County to further assess the
vertical extent of 1,4-dioxane at the Southern Unit. The outer casing of P20D extends to 45
feet below land surface, and the well is screened from 50 to 60 feet below land surface.
In accordance with the June 26, 2019 Pilot Plan approval from the NCDEQ-SWS, in August
2019, GMA also installed two shallow, in -stream piezometers (PZ1 and PZ2) below the ditch
bottom along the southern property boundary near the locations of the historically collected
porewater samples (Figure 1). Each piezometer has a 9-inch long screen set 21 inches below
the ditch bottom. The County uses the instream piezometers to collect representative
groundwater samples to monitor benzene migration and to evaluate groundwater discharge
relationships to the ditch.
To evaluate the integrity of the Southern Landfill Unit cap, and to provide a baseline from which
to evaluate hydrologic improvements following cap upgrades and repairs, Geo Solutions
Limited, Inc. completed electromagnetic (EM) and ground -penetrating radar (GPR) surveys of
the Southern Landfill Unit on June 26', July 1st and July 2nd 2019 (GMA, 2019). The EM survey
identified a couple of areas of elevated apparent conductivity that may correspond to leachate
moving away from the landfill. Additionally, the EM survey indicated that solid waste appears to
extend beyond the toe of the slope to the edge of the gravel road in the proximity of monitoring
wells MW6R, P16R, and P20R. This finding was consistent with GMA's observations of trash
during the installation of well P20D. The GPR survey identified several areas where the landfill
cap was thin or where the cap had completely eroded away. The identified areas included the
northwestern upper slope of the mound, the western narrow berm, and the southern toe north
of monitoring wells P28 and P19. The 2019 GPR results indicated that the impermeable cap
thickness at the Southern Landfill was, on average, 14 inches and ranged from 0 to 32 inches.
Full details of the initial geophysical evaluation can be found in Geo Solutions' report, which was
provided as Appendix F of the July 2019 monitoring report from GMA (GMA, 2019). A revised
version of that report is included here as Appendix B. The revised report includes a correction
to the estimates of the thickness of the impermeable cap layer based on a corrected
understanding of cap construction at the facility. This correction did not affect the implications
or conclusions of the original geophysical evaluation.
After completion of the geophysical survey, the County contracted with an engineering firm
(The Wooten Company) to design cap repairs and stormwater upgrades that will eliminate or
greatly reduce the infiltration of precipitation into the Southern Unit. The County provided the
2019 geophysical report to The Wooten Company to aid their design of cap repairs and
stormwater upgrades for the facility. The Wooten Company (Wooten) resurveyed the Southern

Landfill Unit in early 2020, and in June 2020, Wooten submitted a final design to the County.
This design includes repairing the cap on the western end of the Southern Landfill, regrading
multiple areas to eliminate ponding on the mound, restoring the stormwater conveyance system
to operate as originally designed, and adding new drainage pipes to the southwest corner of the
mound. Repairs at the Southern Unit were completed in June of 2021. Final as -built drawings
of the facility following repairs are provided in Appendix C.
Following completion of the cap repairs and stormwater system upgrades, GMA contacted Geo
Solutions Limited, Inc. to complete a post -repair geophysical evaluation of the Southern Unit.
The purpose of this evaluation was to document the remedial effort of the Pitt County Landfill
by comparing the pre -repair and post -repair geophysical data. Geo Solutions completed repeat
EM and GPR surveys of the Southern Landfill Unit on August 2nd thru August 4th, 2021
(Appendix D).
A comparison of the EM response before and after cap improvements showed a weaker EM
response in areas where new low permeability material was placed to repair eroded areas of
the cap, and in areas where regrading was performed to improve surface water drainage
toward the catch basins (Figure 2). The weaker EM response in these locations was due to the
EM profiler being farther away from the waste following repairs. Based on GPR data, the most
apparent changes in landfill cap thickness from 2019 to 2021 are along the northern repaired
slope where the cap was significantly thickened (15 to 20 inches) during the recent repair
(Figure 7 of Appendix D).
The areas of leachate seeps identified in 2019 appear similar in EM response to the 2021
electromagnetic survey. It is likely too soon to see improvements at seep locations due to the
slow velocity of groundwater at this site. Future geophysical evaluations targeting only the
locations of previously identified seeps may provide a means to monitor the effectiveness of the
recently completed cap improvements.
Overall, geophysical results confirm improvements to the landfill cap thickness and surface
water drainage that should greatly reduce the infiltration of precipitation into the Southern
Landfill Unit. The County continues to monitor the Southern Landfill Unit on its approved semi-
annual schedule.
3.0 WELL REHABILITATION AND MAINTENANCE
Over recent years GMA has noticed an increased frequency of monitoring wells bailing dry (i.e.
water is removed from the well during the purging process faster than water from the formation
can enter the well). Additionally, many of the wells at the Pitt County Landfill remain turbid
after purging, which increases the concentrations of metals in the samples. GMA believes that
many of these monitoring wells, which were installed in the 1990s, are likely affected by a

combination of scale and biological plugging. To extend the life of these monitoring wells, and
to provide representative groundwater samples, Pitt County opted to perform physical well
rehabilitation via surging and pumping all monitoring wells at the facility.
On June 16 and 17, 2021, GMA redeveloped all shallow monitoring wells using a high flow
Waterra° brand inertial foot valve. The foot valve was attached to HDPE tubing, inserted into
the well, and oscillated (pulled up and pushed down) over a short vertical distance. This action
pumps water out of the well while simultaneously surging the well. During the procedure, GMA
monitored for temperature, pH, specific conductance, and turbidity (Appendix Q. GMA also
measured the total well depth before and after the well redevelopment procedure. GMA
removed as much as 0.33 feet of sediment from the bottom of the wells. The effect of these
well redevelopment procedures on the ability of water to move through the well screen has yet
to be fully determined because a new sampling technique (low -flow pumping vs. bailing) was
used for the July 2021 monitoring event.
4.0 JULY 2021 SEMI-ANNUAL MONITORING EVENT
GMA performed the semi-annual monitoring event at the Southern Unit on July 20 thru July 22,
2021. Historically, the County has monitored the Southern Landfill Unit for the parameters
identified in Appendix I of 40 CFR Part 258 plus 1,4-dioxane on a semi-annual basis and for the
parameters listed in 40 CFR Part 258 Appendix II on an annual basis. Based on the lack of
detections of Appendix II parameters over the last 20 years, GMA, on behalf of the County,
requested that the NCDEQ SWS allow a reduction in sampling frequency for Appendix II
constituents. Specifically, we requested that the NCDEQ SWS allow the County to sample for
Appendix II constituents on a biennial basis with the next scheduled Appendix II sampling event
occurring during July 2022. The NCDEQ SWS approved this request on July 2, 2020 (Appendix
A). Therefore, during the July 2021 monitoring event, the County analyzed all groundwater and
surface -water samples for Appendix I parameters and for 1,4-dioxane.
Twenty-six groundwater -monitoring wells and two temporary groundwater piezometers
comprise the groundwater -monitoring network for the entire landfill facility (Figure 1, Table 1).
GMA also monitors surface water levels at thirteen staff gauges in the ditches surrounding the
site. The water -quality monitoring network used for the July 2021 semi-annual monitoring of
the Southern Unit consisted of one background monitoring well (P4), seven 'shallow' wells
located around the Southern Mound (P12, P16R, P17, P19, P20R, P28, and MW6R), a deep'
well located south of the Southern mound (P20D), a well located between the Northern and
Southern Landfill Unit (P29), two temporary groundwater piezometers (PZ1 and PZ2), a
hydraulically-upgradient surface water sample location (SW1), and a hydraulically-downgradient
surface water sample location (SW2) (Figure 3).

4.1 Groundwater Hydrology
GMA measured static water levels 29 monitoring wells and temporary piezometers (Table 2)
and at 12 staff gauges (Table 3) on July 20, 2021. Depth to groundwater in monitoring wells at
the site ranged from approximately 2.89 to 13.41 feet below the land surface. Estimates of
groundwater velocity (Table 4) ranged from approximately 0.002 to 0.033 feet/day, or 0.71 to
12.18 feet/year. These represent low groundwater velocities consistent with the composition
and permeability of materials in the shallow aquifer.
An equipotential map prepared using these water -level measurements (Figure 4) indicates that
groundwater flow patterns were generally similar to other recent flow patterns prepared for this
facility during the summer when groundwater levels are relatively low. Figure 3 indicates that
the primary horizontal component of groundwater flow at the Southern Unit was directed
toward the large ditch forming the southern boundary of the facility.
Summer groundwater flow patterns suggest that a groundwater divide or perched groundwater
likely exists beneath each of the landfill units during the summer months. Historically,
groundwater samples collected and analyzed from wells P4, P5, and P6 have been used to
assess background groundwater chemistry. The July 2021 equipotential map indicates that
groundwater elevations in wells P6 and P4 may be lower than groundwater elevations in the
adjacent Northern mound. Further assessment of this finding is warranted.
During the July 2021 monitoring event, PZ1 and PZ2 groundwater elevations were slightly lower
than the surface water elevation outside of the piezometers (Tables 2 and 3). This downward -
directed hydraulic relationship indicates that the southern boundary ditch was losing water to
the groundwater system at the time that GMA collected these measurements.
4.2 Sample Collection and Analyses
For monitoring of the Southern Unit, GMA analyzed water samples collected from ten
monitoring wells, two temporary piezometers, and two surface water sampling locations as
shown on Figure 3. During sampling, GMA collected field water -quality parameters to document
adequate purging prior to sample collection and to aid in evaluating groundwater chemistry at
the site (Table 5). We provide a copy of the well sampling record in Appendix F. All
groundwater sampling methods adhered to the procedures described in the EPA Region 4 SESD
Operating Procedure for Groundwater Sampling (USEPA, 2017, SESDPROC-301-R4).
Historically, GMA has collected groundwater samples at the landfill using the multiple -volume
purge method that utilizes bailers to purge 3 well volumes prior to sample collection. During
the July 2021 event, GMA sampled all wells using the low -flow sampling method. Our goal was
to evaluate whether the low -flow method would be more efficient and whether this method
would result in less turbid samples that more accurately indicated dissolved groundwater

concentrations. To compare the two methods, GMA sampled one well, MW-6R, using both
methods.
GMA transferred all samples to Environmental Conservation Laboratories, Inc. (ENCO) in ice -
filled coolers under chain -of -custody protocol for analysis of Appendix I parameters and 1,4-
dioxane. Copies of the chain -of -custody forms and analytical reports are provided in Appendix
G. Consistent with the May 29, 2018 NCDEQ-SWS memo, ENCO analyzed the samples using
EPA -approved analytical methods sufficiently sensitive to detect the presence of regulated
constituents at or below the applicable standard (unless no such method currently exists, e.g.
for vinyl chloride analysis).
4.3 Analytical Results and Discussion
Twenty-five parameters (acetone, antimony, 2-butanone, barium, benzene, beryllium, carbon
disulfide, chlorobenzene, chromium, cobalt, copper, 1,4-dichlorobenzene, 1,1-dichloroethane,
1,4-dioxane, ethylbenzene, lead, nickel, selenium, thallium, toluene, vanadium, vinyl chloride,
m,p-xylenes, o-xylene, and zinc) were detected at concentrations above their method detection
limits during the July 2021 sampling event (Table 7). Seven targeted compounds (barium,
chlorobenzene, 1,4-dioxane, benzene, lead, vinyl chloride, and zinc) were detected at
concentrations exceeding the NCAC 02L standard, and six parameters (antimony, beryllium,
cobalt, nickel, thallium, and vanadium) were detected at concentrations above their Interim
Maximum Allowable Concentration (IMAC) during this monitoring event (Table 7).
Zinc and carbon disulfide were detected in the equipment blank. GMA believes that zinc
concentrations are related to residual powder from the manufacturing process used to produce
the'powder-free' nitrile gloves that we used during sampling. Nitrile gloves are also the likely
source of the carbon disulfide detected in the equipment blank (USGS, 2012). Low, estimated
(i.e. "J-flaggefl concentrations of antimony and barium were also detected in the equipment
blank during this sampling event. The source of these two constituents in the equipment blank
is unknown. The laboratory did not detect antimony in any other sample collected during this
event.
Samples from wells P16R, P19, P20R, and P29 contained benzene (2.5 µg/L, 4.2 µg/L, 1.9 µg/L,
and 1.4 µg/L, respectively) above the 1.0 µg/L NCAC 02L groundwater standard. Importantly,
benzene was not detected in either in -stream piezometer sample (PZ1 and PZ2). Therefore,
there continues to be no evidence that benzene is migrating off of the landfill property at this
time.
1,4-Dioxane was detected in wells MW6R, P16R, P17, P19, P20R, and P29 (6.2 µg/L, 93 µg/L,
5.2 µg/L, 180 µg/L, 87 µg/L, and 170 µg/L, respectively) at concentrations exceeding the NCAC
02L groundwater standard of 3 µg/L. The detection of 1,4-dioxane in well P29 located between

July 2021 Semiannual Water Quality Monitoring Report
Southern Portion of the Pitt County Solid Waste Municipal Landfill
December 6, 2021
Page 10 of 13
the two landfill units indicates that 1,4-dioxane may be leaching from both the Southern and
Northern mounds. 1,4-Dioxane was also detected in the down -gradient surface water sample,
SW2, and in the samples from the in -stream piezometers, PZ1 and PZ2, but the concentrations
were below the NCAC 02B and NCAC 02L standards, respectively. Importantly, the lab did not
detect 1,4-dioxane in the sample collected from the "deep" down -gradient monitoring well,
P20D.
Samples from wells MW6R, P16R, P19, and P29 contained concentrations of barium (1010 µg/L,
1000 µg/L, 1620 µg/L, and 1200 µg/L, respectively) above the NCAC 02L standard of 700 µg/L.
Barium occurs naturally in the native soils at the Pitt County Landfill as evidenced by the
ubiquitous occurrence of this alkaline metal in all samples collected at the site, including those
located in up -gradient off -site areas. GMA has previously demonstrated that barium is often a
constituent of the particulate matter in many of the groundwater samples collected at the Pitt
County Landfill and that dissolved barium concentrations do not exceed the NCAC 02L standard
in some locations (GMA, 2011 and 2015). Despite the apparent natural occurrence of barium at
this site, the concentrations of barium at all locations at the Pitt County Landfill (e.g. well P19)
are unlikely to be solely attributable to natural sources.
Upgradient surface water sample SW1 contained concentrations of cobalt and lead above the
NCAC 02B surface -water standards, which is fewer than the number of metals that have
exceeded the standards at this location in recent years (e.g. 4 parameters above the 2L
standards in July 2020). Initial metal exceedances at this upgradient surface -water sample
location corresponded with highway construction on the adjoining parcel directly next to the
SW1 sampling location. Per the NC DOT website, construction on the bypass started in August
2016 and completed in November of 2019 (NC DOT, 2019). The lab did not detect any of the
target parameters above the 2B surface -water standards in the down -gradient sample, SW2.
4.4 Evaluation of Low -Flow Sampling Procedures
The sample collected from monitoring well MW6R using the low -flow sampling procedure
contained an increased number of metals detections compared to the sample collected using
the traditional multi -volume purge technique with delayed metals collection (n = 8 vs. n = 1,
Table 7). This increase in detections of metals in the low -flow sample was attributed to
increased turbidity at the time of sample collection. During the low -flow pumping, turbidity
remained elevated (> 1,000 NTU) even after 32 minutes of pumping. When utilizing the multi -
volume sampling method, GMA has historically utilized a delayed metals collection period where
the metals sample is collected after the particulates have been allowed to settle out of the
water column following purging (but within 24 hours). The turbidity during the delayed metals
sample collection at MW6R was only 36.5 NTU. Volatile organic samples were still collected
immediately after purging.

1,4-Dioxane concentrations in well MW6R were comparable between the two methods (6.2 pg/L
vs 7.0 pg/L). Because groundwater from many of the shallow wells at the Pitt County Landfill is
turbid, GMA plans to use the multi -volume sampling method with delayed metals collection in
the future for shallow wells. We will use the low -flow protocol for deep monitoring wells where
this method is most efficient. All methods will follow published Environmental Protection
Agency (EPA) guidelines (USEPA, 2017).
5.0 CONCLUSIONS AND FUTURE WORK
Pitt County has recently completed a $1.065 million cap improvement project at the Southern
Unit of the Pitt County Landfill. These upgrades were part of an approved pilot study for
corrective action following detections of 1,4-dioxane above the NCAC 02L groundwater
standard. Following completion of the construction project in June 2021, the County repeated
geophysical testing of the Southern Unit to help document the extensive repairs and to evaluate
hydrologic improvements. A comparison of the recent geophysical evaluation with the
evaluation performed prior to the cap improvement project revealed the areas where cap
thickness has been increased and where extensive surface regrading was necessary to ensure
proper functioning of the stormwater drainage system.
GMA anticipates that the completed cap improvements will reduce infiltration of water through
the cap and better protect the groundwater from further contamination via leaching from
landfill waste at the Southern Unit. At present, however, it is too soon to see hydraulic
improvements or reductions in contaminant levels. The County will continue to monitor
groundwater levels and contaminant concentrations for the next year to assess the
effectiveness of the cap and stormwater system upgrades, as approved by the NCDEQ-SWS in
their June 26, 2019 letter (Appendix A). This will to allow time for the existing groundwater to
drain from the Southern mound prior to making an assessment of hydraulic improvements and
will allow the County to evaluate how the improvements affect seasonal shifts in groundwater
flow patterns at the facility.
During the July 2021 monitoring event, 1,4-dioxane, barium, and benzene were detected at
concentrations exceeding the NCAC 02L groundwater standards at multiple locations
surrounding the Southern Unit. However, these constituents were not detected at
concentrations above state standards in groundwater samples collected from just below the
southern property ditch, in the deep monitoring well located down -gradient of the Southern
Landfill Unit (P20D), or in the downgradient surface -water sample. These results suggest that
1,4-dioxane, benzene, and waste -related barium are not migrating off -site at concentrations
exceeding the NCAC 02L standard at this time. The absence of these compounds in monitoring
well P20D also indicates that 1,4-dioxane, benzene, and non-native barium have not migrated
out of the Surficial/Yorktown Aquifer at the site.

well P20D also indicates that 1,4-dioxane, benzene, and non-native barium have not migrated
out of the Surficial/Yorktown Aquifer at the site.
The County continues to monitor both the Northern and Southern Landfill Units on their
approved schedules (semi-annually for the Southern and annually for the Northern).
The next semi-annual monitoring event at the Pitt County Solid Waste Municipal Landfill is
scheduled for January of 2022. This monitoring event will include the analysis of water samples
for Appendix I parameters, per the approved Water Quality Monitoring Plan dated September 8,
1994. The sampling network will continue to include wells P19, P20D, and P29 and the two in -
stream piezometers.

Dear Mr. Demary:
ROY COOPER

MICHAEL SCOTT
Director
The NC Solid Waste Section has completed a review of the Proposal for Assessment of Benzene
Contamination Migration dated March 15, 2017 (DIN 27528) submitted on your behalf by Groundwater
Management Associates, Inc. (GMA) for the closed Pitt County MSW Landfill, NC Solid Waste Permit
Number 7401. During the January 2017 semiannual water quality monitoring event benzene was
detected at concentrations exceeding the NC 2L Groundwater Standards in two groundwater monitoring
wells.
Based upon the groundwater exceedances, Pitt County is requesting to collect two pore water samples
from the beneath the southern boundary ditch and analyze for Appendix I constituents. The proposed
sampling locations are located downgradient of groundwater monitoring well P20R and will be sampled
during the July 2017 semiannual water quality monitoring event.
As a result, the Proposal for Assessment of Benzene Contamination Migration is approved as described. If
you have any questions, please feel free to contact me by email at [e-mail] or
by phone at 828.296.4706. Thank you for your continued cooperation with this matter.

Pitt County Landfill, Solid Waste Permit Numbers 7401-MSWLF- and 7401-MSWLF-1974.
To address the 1,4-Dioxane being detected within the groundwater at the landfill, Pitt County is
proposing to:
1) Delineate the vertical and horizontal extent of 1,4-Dioxane by installing two additional groundwater
monitoring wells (Type II and Type III) and six surface water gauges;
2) Initiate a one-year pilot study to determine the effectiveness of cap upgrades and repairs to see if
they have limited the infiltration of rainwater into the soil cap, and if they have reduced leachate
volumes and concentrations. Geophysical testing of the Southern Unit only will also be conducted to
evaluate landfill cap integrity. The County will repair any areas identified by the geophysical testing
and will inspect surface water drainage structures on the mound to ensure that they are operating as
designed. Once repairs are made, geophysical testing will be repeated to document hydrologic
benefits from cap repairs and to determine if the repairs have significantly reduced rainfall infiltration;
and
3) Install two instream piezometers approximately 1.5 feet below the ditch bottom at the locations of
the currently collected porewater samples. The instream piezometers will be used to collect
representative groundwater samples, measure groundwater levels, and determine any discharge
relationships at repeatable locations just below the stream bed.
Based upon a review of the Proposal for 1,4-Dioxane Assessment and Pilot Study at the Pitt County
Municipal Solid Waste Landfill, the Section approves the activities as described. If you have any
questions or concerns regarding this letter, please feel free to contact me by phone at 828.296.4706

Pitt County
Solid Waste Permit Number 7401-MSWLF-1974
FID 1417776
Dear Mr. Demary,
The Solid Waste Section (Section) has completed a review of the Request for Reduced Sampling
Frequency of Appendix II Constituents dated July 1, 2020 (FID 1417773) and submitted on your behalf
by Groundwater Management Associates, Inc. for the closed and unlined Pitt County Landfill Southern
Unit, Solid Waste Permit Number 7401-MSWLF-1974.
In accordance with 15A NCAC 13B .1634 a request was provided to the Section to modify the
groundwater monitoring frequency for the full set of Appendix II constituents because no Appendix II
constituents have been detected since 2014. Pitt County is requesting to sample for Appendix II
constituents on a biennial basis with the next scheduled Appendix II sampling event occurring during
July 2022. The County will continue to sample for Appendix I parameters and for 1,4-dioxane on a
semi-annual basis.
Based upon a review of the Request for Reduced Sampling Frequency of Appendix 11 Constituents, the
Section approves the request as written at this time. If you have any questions or concerns regarding
this response letter, please feel free to contact me by phone at 828.296.4706 or by email at

2.0 Background
GMA has been contracted to evaluate the integrity of the landfill cap of the Southern Unit
at the Pitt County Landfill located in Greenville, NC. It is suspected that degraded or
missing areas of impermeable landfill cap material may be leading to intrusion of surface
water into the landfill and potentially leading to elevated constituent levels in several
groundwater monitoring wells. GMA has identified areas of seeps along the toes of the
berms based on visual inspections. GMA has also identified eroded or damaged areas of
1

the landfill slope, some of which have been repaired. The Southern Unit is
approximately 26.5 acres based on the toe of the landfill slope. GMA contacted with Geo
Solutions to provide a geophysical evaluation of the Southern Unit. Geo Solutions
developed a technical approach to map the horizonal extents of the buried solid waste,
evaluate the landfill cap integrity, as well as the depth to solid waste, and, where possible,
detect areas of seeps and potential leachate plumes away from the toe of the landfill.
3.0 Technical Approach
Geo Solutions completed the following technical approach to evaluate the Southern Unit
of the Pitt County Landfill. Field work for this project was conducted on the June 26",
July 1st, and July 2nd 2019.
3.1 Multifreauencv Electromagnetic (EM) Evaluation
Geo Solutions completed an EM evaluation of the Southern Unit and surrounding area,
which totaled approximately 37.5-acres. The EM method is a non -contact (uncoupled)
geophysical method that utilizes a multiple frequency electromagnetic detector (Geophex
Model GEM-2). The EM instrument collects electromagnetic responses in the in -phase
(metal detection mode) and quadrature (conductivity) mode. When a target is exposed to
a low -frequency electromagnetic field, it produces a secondary magnetic field. By
measuring the broadband spectrum of the secondary field, it is possible to obtain a
distinct spectral signature that may uniquely identify the target. Thus, the response
spectrum from conductive material is a "fingerprint" of the composition of the target.
This forms the general principles of electromagnetic induction spectroscopy (EMIS)
(Won 1998). The GEM-2 operates in a frequency band between 30 Hz and 93kHZ. The
unit collects data at a rate of 30Hz or 30 data points per second. The GEM-2 detection
depth is inversely related to frequency. In other words, a low frequency signal travels
farther into the earth and can "see" deep features, while a high frequency signal can only
travel short distances and therefore can only "see" shallow features. Therefore, if
materials, or conductive groundwater, at depth are concentrated in a particular zone, one
frequency may "see" the affected area more clearly than others. Below is a nomogram

created by Geophex to display the estimated depth of detection as it relates to frequency
and geology.

Multiple frequency electromagnetic evaluations are useful in characterizing targeted
materials, as well as the distribution of elevated conductivities in soil pore water and
groundwater across a site.
For this project the GEM-2 was operated in a wireless configuration while evaluating the
site. The GEM-2 unit was mounted on a PVC tubular sled and towed with a Polaris
Ranger all -terrain vehicle (ATV). The advantage of mounting the GEM-2 on a sled is
related to efficiency of data collection and stability of the unit. When mounted on the
sled, the GEM-2 is positioned approximately 0.75 meters above the ground surface
(Figure 3 below). The GEM-2 was connected to a Hemisphere Model A-325 GPS unit,
which is augmented by the Wide Area Augmentation System (WARS) and is capable of
submeter accuracy and provided real-time location data. On average, the EM profiles
were collected at a spacing of 5-10 feet apart (Figure 4). EM profile spacing was greater
in some locations due to slope steepness. The EM data were collected simultaneously at
six varying frequencies (1,470 Hz, 4,110 Hz, 9,810 Hz, 32,190 Hz, 60,000 Hz, and
90,030 Hz). The EM data were transferred from the GEM-2 to a laptop computer using
3

the WinGEM Version 3 software provided by the manufacturer. During the transfer
process, the WinGEM software assigns Universal Transverse Mercator (UTM) metric
coordinates to each data collection station, and it calculates the apparent conductivity for
each frequency collected using the system software. These data were then transferred to
a Microsoft Excel spreadsheet. Geo Solutions used these data to compile a series of maps
illustrating various responses using a simple mapping program (Golden Software's Surfer
Mapping System Version 15). The 32,190 Hz frequency best represents the EM response
over the site and was used to create figures for this report. The best frequency response
(32,390 Hz) is likely related to the depth of buried solid waste and is consistent with the
response observed at other landfills. Based on the skin depth nomogram, the 32,190 Hz
is most representative of the upper 3 to 6 feet. The 90,030 Hz frequency response was
weaker, however it may provide information related to the cap integrity.

3.2 Ground -penetrating Radar (GPR) evaluation
Ground -penetrating radar (GPR) is and effective tool used to measure vertical and
horizontal variations of certain electrical properties of soil. GPR is a noninvasive
electromagnetic geophysical technique that utilizes radio frequency energy to detect
various layers in the earth's shallow subsurface. It is widely used in environmental site
characterization and landfill construction verification. It may be deployed from the
surface by hand or vehicle. GPR has the highest resolution of any geophysical method
for imaging the subsurface, with up to centimeter scale resolution. However, GPR
investigations are affected by subsurface conditions, such as
• Soil composition affects the depth of detection (i.e. higher clay content generally
equals lesser depths of penetration of the radar signal and thus the lesser depths of
detection).
• Presence of highly conductive material (i.e., less resistive material) generally
equals poorer quality of recovered data and shallower sounding depths.
Conductive material enhances the attenuation of the radar signal, thus reducing
the depth of penetration. Landfill waste is conductive, which makes estimating
the depth to the top of waste possible, however the signal does not penetrate deep
into the waste.
For this investigation, the purpose of the GPR evaluation was to detect changes in the
impermeable cap thickness and depth to solid waste along transects across the landfill.
The GPR data were collected using a GSSI Model SIR 4000 GPR unit equipped with a
200 MHz antenna and survey wheel. The GPR was coupled to a submeter accuracy
Hemisphere Model A-325 GPS unit which is augmented by WAAS, which provided real
time location data along each profile. The antenna, GPS, and survey wheel were towed
with the Polaris Ranger ATV with the GPR console on board the ATV (Figure 5 below).
A second GPS (Trimble Yuma) was carried onboard the ATV as well with the planned
profile lines loaded (Figure 5 below). Following the guidance from the Trimble GPS, the
Con

ATV towed the GPR along each of the planned profile lines. A total of 92 GPR profiles
spaced approximately 20 feet apart, were collected on North to South and South to North
orientations (Figure 6.) The total linear footage of data collected was 63,930, feet or
approximately 12 miles. Once the GPR data were collected, the data were post
processed in the office using Radan 7 software provided by GSSL Each profile was
reviewed, and the image clarity was enhanced through processing. The suspected landfill
cap base and top of solid waste were manually picked along each profile. Each of these
points included depth and geographical coordinates. The data for each profile were
exported from Radan 7 to MS Excel where the data could then be mapped (Digital
Appendix A.).

4.0 Results
4.1 Electromagnetic Evaluation (EM) Results
Maps illustrating the results of the 32,190 Hz frequency apparent conductivity response
and 32190 Hz in -phase response are presented as Figure 7 and Figure 8, respectively. The
32,190 Hz frequency was chosen to display the results of the EM evaluation because it
provided the most uniform representation of the overall database in comparison to the
other six frequencies. Shown on Figure 7, the orange and red hues are representative of
elevated subsurface apparent conductivities which are related to buried waste and
suspected conductive soil pore water and groundwater, while the green and faint yellow
hues are related to background site conditions. Shown on Figure 8, orange, red, and dark
blue -purple hues indicate areas of buried metallic materials, while the faint yellow and
green hues indicate background site conditions. Based on the EM response, one hundred
and seventy-five (175) stations were chosen to represent the solid waste fill boundary,
starting from the North side of the landfill moving clockwise in a full circle around the
Southern Unit (Appendix B.) Figure 9 is a map of the 90,030 Hz EM apparent
conductivity response. This higher frequency response is more representative of the
upper 3 feet, based on the skin depth nomogram provided by Geophex. Notable
observations made based on the EM response across the site are detailed below:
• Between stations 150 and 1, from the Northwest corner eastward, there is an area
of elevated apparent conductivity that extends beyond the solid waste fill
boundary. This is directly below a large area of slope erosion, and the location of
several visible seeps (Appendix C, Photographic Log).
• Between stations 35-37, which is located at the southeast corner of the southern
unit, it is suspected that solid waste extends beyond the toe of the slope. Here,
relatively high apparent conductivity and in -phase values were noted into the edge
of the gravel driveway. This is very close to monitoring well MW-6R.
N.

• Based on the apparent conductivity and in -phase responses, several monitoring
wells appear to be positioned within or very near solid waste. These monitoring
wells include P-16-R, MW-6R, and P20R.
• The area outside the solid waste fill boundary on the southside of the landfill,
between monitoring wells P-17 and P-28, there is an area of slightly elevated
apparent conductivity. This may be related to conductive groundwater moving
away from the landfill in a linear southeast orientation.
• Shown on Figure 9, the 90,030 Hz response shows some detail in the area of
erosion on the North side of the landfill. These areas are pointed out on Figure 9.
Here, the very dark red areas across the landfill are interpreted as areas of either
very concentrated solid waste or waste near the surface.
4.2 Ground -penetrating Radar (GPR.) Results
The picked layers, as interpreted from the GPR data as bottom of impermeable cap and
top of solid waste, were combined into a single MS Excel file where maps could be
created (Digital Appendix A.). Based on the GPR data, there are two distinct layers that
were detected. The upper layer is the interface between the top of landfill cap and base of
topsoil. The second is the top of solid waste. These layers can be seen on Figure 10.
Figure 11 is a map of the impermeable landfill cap estimated thickness. Blue hues
represent 0-12 inches of impermeable cap, green hues 12-20 inches, and yellow hues 20-
36 inches. The estimated average impermeable cap thickness is 14 inches and ranged
from 0-32 inches in thickness. Figure 12 is a map of the depth to the top of solid waste
fill. Here, blue hues represent 0-12 inches to the top of solid waste, green hues 12-24
inches, and yellow orange hues 24-48 inches. The estimated average depth to solid waste
is 24 inches and ranges from 0-47 inches. Notable observations made based on the GPR
interpretation across the site are detailed below:
9

• The depth to solid waste at the area of erosion on the North side of the landfill
was estimated to be in the 12-18 inches range. This area of erosion is fairly
widespread across the northwestern upper slope of the landfill.
• The western narrow berm has a relatively thin cap especially along the slope toes.
The depth to solid waste in this area is also relatively shallow. On the western
edge near the toe, waste is visible at the land surface where tires and rims are
exposed (Appendix C. Photographic Log).
• The southern toe of the landfill, North of monitoring wells P-28 and P-19, is
suspected to have a thin cap and solid waste very near the land surface.
• There are two areas on the southern slope that are located northwest of monitoring
well P-20R that appears to have been areas of excavation and repair of the landfill
cap (Figure 13 and 14). The location of the radar record shown on Figure 14
corelates well to an area of bare soil that can be viewed on historic aerial imagery
between years 2013 and 2015. This is thought to be the location of an area where
an excavator became stuck while installing a drain pipe. The locations of these
areas are shown on Figures 11 and 12.
• The coordinates for this location are (Fasting 279112.5, Northing 3941816 UTM
meters zone 18N).
• There are other small localized areas throughout the landfill that are interpreted to
have a thin cap, and/or shallow buried solid waste, which can be seen on Figures
11 and 12.

5.0 Conclusions and Recommendations
Electromagnetic and ground -penetrating radar evaluations were carried out as part of the
geophysical investigation at the Southern Unit of the Pitt County Landfill, located in
Greenville, NC. The objectives of the geophysical evaluation were to map the horizonal
extents of the buried solid waste, evaluate the landfill cap integrity as well as the depth to
solid waste, and, where possible, detect areas of seeps and potential leachate plumes
away from the toe of the landfill. EM and GPR profiles were acquired over the 37.5 acre
site.
The solid waste fill boundary was successfully mapped based on the contrast in response
over solid waste as compared to background site conditions. Moreover, areas of elevated
apparent conductivity outside the solid waste fill boundary would suggest that possible
leachate in the soil pore water and/or groundwater was detected and mapped. Along the
southern landfill boundary, most notably at the Southeast corner it appears that solid
waste may extend beyond the toe of the slope near monitoring well MW-6R. Several
monitoring wells appear to be positioned within or very near solid waste. These
monitoring wells include P 16R, MW-6R, and P20R.
The GPR evaluation indicates variable impermeable cap thicknesses, and depths to solid
waste across the landfill. Areas of visible erosion on the slopes correlate well to
relatively shallow buried waste. The western narrow berm is interpreted to have shallow
buried solid waste, especially at the toes. The western toe has solid waste exposed at the
surface. Two areas of suspected excavation and repair was detected Northwest of
monitoring well P20R. These areas of degraded or thin cap may be contributing to
surface water intrusion into the landfill.
We suggest that borings or hand auger samples be collected to verify the geophysical
results. Further, we suggest that areas that we have identified as possible leach plumes be
investigated and sampled. Note that the anomalies identified in this report are not
confirmed until they are drilled or sampled. Additionally, there may be degraded areas
11

across the landfill that were not traversed during the geophysical evaluation either
because they fell between profile, lines or they were not accessible due to the steepness of
the slopes.

1.0 Introduction and Background
Geo Solutions Limited, Inc. (Geo Solutions) is pleased to submit this report to
Groundwater Management Associates Inc (GMA) for a follow up geophysical evaluation
of the Southern Unit at the Pitt County Landfill located in Greenville, North Carolina.
Figure 1 is a site map of the landfill and monitoring well network.
In 2019, GMA was contracted to assess the integrity of the landfill cap of the Southern
Unit at the Pitt County Landfill located in Greenville, NC. It was suspected that
degraded or missing areas of impermeable landfill cap material may have been leading to
intrusion of surface water into the landfill and potentially leading to elevated constituent
levels in several groundwater monitoring wells. As one phase of this assessment, GMA
contracted Geo Solutions to complete a geophysical evaluation. In July 2019, Geo
Solutions completed a detailed electromagnetic (EM) and ground -penetrating radar
(GPR) evaluation of the Southern Unit which is approximately 26.5 acres. Here, Geo
Solutions identified the solid waste boundary, areas of suspected leachate seeps, and thin
areas of landfill cap. GMA provided a comprehensive report of the landfill evaluation to
the Pitt County Landfill engineer. This document was used to develop repair plans of the
Southern Unit. Between 2019 and 2021, the Southern Unit was repaired by increasing
the cap thickness and installing a surface water control system to divert surface water off
of the landfill. The most significant areas of landfill cap repair were completed on the
slopes of the western half of the landfill. GMA contacted Geo Solutions to complete a
post repair geophysical evaluation of the Southern Unit. The purpose of this evaluation
was to document the remedial effort of the Pitt County Landfill by comparing the 2019
and 2021 geophysical data of the Southern Unit.

2.0 Technical Approach
Geo Solutions completed the following technical approach to evaluate the Southern Unit
of the Pitt County Landfill. An effort was made to replicate the 2019 geophysical
evaluation for a more accurate comparison. Field work for this project was conducted on
August 02, 2021— August 04, 2021.
2.1 Multifreauencv Electromavnetic (EM) Evaluation
Geo Solutions completed an EM evaluation of the Southern Unit and surrounding area,
which totaled approximately 36-acres. An effort was made to collect the EM profiles at a
similar location and density as the 2019 evaluation. The EM method is a non -contact
(uncoupled) geophysical method that utilizes a multiple frequency electromagnetic
detector (Geophex Model GEM-2). The EM instrument collects electromagnetic
responses in the in -phase (metal detection mode) and quadrature (conductivity) mode.
When a target is exposed to a low -frequency electromagnetic field, it produces a
secondary magnetic field. By measuring the broadband spectrum of the secondary field,
it is possible to obtain a distinct spectral signature that may uniquely identify the target.
Thus, the response spectrum from conductive material is a "fingerprint" of the
composition of the target. This forms the general principles of electromagnetic induction
spectroscopy (EMIS) (Won 1998). The GEM-2 operates in a frequency band between 30
Hz and 93kHZ. The unit collects data at a rate of 30Hz or 30 data points per second.
Multiple frequency electromagnetic evaluations are useful in characterizing targeted
materials, as well as the distribution of elevated conductivities in soil pore water and
groundwater across a site. For this project the GEM-2 was operated in a wireless
configuration while evaluating the site. The GEM-2 unit was mounted on a PVC tubular
sled and towed with a Polaris Ranger all -terrain vehicle (ATV) (Appendix A.). The
advantage of mounting the GEM-2 on a sled is related to efficiency of data collection and
stability of the unit. When mounted on the sled, the GEM-2 is positioned approximately
0.75 meters above the ground surface. The GEM-2 was connected to a Hemisphere
Model A-325 GPS unit, which is augmented by the Wide Area Augmentation System
(WAAS) and is capable of submeter accuracy which provided real-time location data.
N

On average, the EM profiles were collected at a spacing of 5-10 feet apart except where
the slope was too steep or where areas were too wet along the base of the landfill (Figure
2). The EM data were collected simultaneously at six varying frequencies (1,470 Hz,
4,110 Hz, 9,810 Hz, 32,190 Hz, 60,000 Hz, and 90,030 Hz). The EM data were
transferred from the GEM-2 to a laptop computer using the WinGEM Version 3 software
provided by the Geophex. During the transfer process, the WinGEM software assigns
Universal Transverse Mercator (UTM) metric coordinates to each data collection station.
Using software developed by Geophex, the apparent conductivity for each frequency
collected was calculated. These data were then transferred to a Microsoft Excel
spreadsheet. Geo Solutions used these data to compile a series of maps illustrating
various responses using a simple mapping program (Golden Software's Surfer Mapping
System Version 17). The 32,190 Hz frequency best represents the EM response over the
site and was used to create figures for this report. The best frequency response (32,390
Hz) is likely related to the depth of buried solid waste and is consistent with the response
observed at other landfills. The 32,190 Hz response was also selected to display in the
2019 evaluation.
2.2 Ground-nenetratina Radar (GPR) Evaluation
Ground -penetrating radar (GPR) is and effective tool used to measure vertical and
horizontal variations of certain electrical properties of soil. GPR is a noninvasive
electromagnetic geophysical technique that utilizes radio frequency energy to detect
various layers in the earth's shallow subsurface. It is widely used in environmental site
characterization and landfill construction verification. It may be deployed from the
surface by hand or vehicle. GPR has the highest resolution of any geophysical method
for imaging the subsurface, with up to centimeter scale resolution. However, GPR
investigations are affected by subsurface conditions, such as soil composition which
affects the depth of detection (i.e. higher clay content generally equals lesser depths of
penetration of the radar signal and thus the lesser depths of detection). Also, the presence
of highly conductive material generally equals poorer quality data and shallower
3

sounding depths. Landfill waste is conductive and while estimating the depth to the top
of waste possible, the signal does not penetrate deep into the waste.
An effort was made to collect the GPR profiles along the same transects as collected in
2019. For this investigation, the purpose of the GPR evaluation was to evaluate the
landfill cap thickness and depth to solid waste to provide comparison data to the 2019
GPR evaluation. The GPR data were collected using a GSSI Model SIR 4000 GPR unit
equipped with a 200 MHz antenna and survey wheel. The GPR was coupled to a
submeter accuracy Hemisphere Model A-325 GPS unit which is augmented by WAAS,
and provided real time location data along each profile. This is the same GPR system
deployed in 2019. The antenna, GPS, and survey wheel were towed with the Polaris
Ranger ATV with the GPR console on board the ATV (Appendix A.). A second GPS
(Trimble Yuma) was carried onboard the ATV as well with the 2019 GPR profile lines
loaded. Following the guidance from the Trimble GPS, the ATV towed the GPR along
each of the planned profile lines (Appendix A.). A total of 93 GPR profiles spaced
approximately 20 feet apart, were collected on North to South and South to North
orientations (Figure 3). Is was not possible to follow the exact path of the 2019 profiles
in some cases due to newly installed surface water collection infrastructure, steep slopes,
and wet muddy terrane. Once the GPR data were collected, the data were post processed
in the office using Radan 7 software provided by GSSI. Following the same process as
completed in 2019, each GPR profile was reviewed and the image clarity was enhanced.
The suspected landfill cap base and top of solid waste were manually picked along each
profile.

3.0 Results
3.1 Electromagnetic Evaluation (EM) Results
Maps illustrating the results of the 32,190 Hz frequency apparent conductivity response
and 32190 Hz in -phase response are presented as Figures 4 and Figure 5, respectively.
Shown on Figure 4, the orange and red hues are representative of elevated subsurface
apparent conductivities which are related to buried waste and suspected conductive soil
pore water and groundwater, while the green and faint yellow hues are related to
background site conditions. Shown on Figure 5, orange, red, and dark blue -purple hues
indicate areas of buried metallic materials, while the faint yellow and green hues indicate
background site conditions. Based on the EM response, the suspected landfill boundary
has not changed from the 2019 evaluation. Refer to Appendix B. of the 2019 eport for
landfill boundary coordinates. The EM response was very similar across the majority of
the landfill from 2019 to 2021 with the exception of the repaired slopes. Here, the
strength of the EM response is weaker which is indicative of a thicker landfill cap (i.e. the
EM profiler is farther away from the waste thus has a weaker response). The areas of
seeps identified in 2019 appear to be similar in EM response in 2021.
3.2 Ground -penetrating Radar (GPR) Results
The picked layers interpreted from the GPR data as bottom of impermeable cap and top
of solid waste, were combined into a single MS Excel file where maps could be created.
Based on the GPR data, the base of landfill cap and top of solid waste are visible. Figure
6 is a cross sectional image from GPR data of the landfill which has these suspected
layers delineated. Figure 7 is a plan view map of the suspected landfill cap thickness
based on the GPR data. Here, blue hues represent areas of a thinner cap whereas red hues
represent areas of a thicker cap. The most apparent change in the landfill cap thickness
from 2019 to 2021 is along the northern repaired slope where the landfill cap appears to
be relatively thick from the recent repair. Figure 8 is a plan view map of the suspected
depth to solid waste. Here, blue hues represent areas of shallower depth to the top of
waste whereas orange to red hues represent areas of greater depths to the top of waste.

The most apparent change in the landfill cap thickness from 2019 to 2021 is along the
northern repaired slope where the landfill cap appears to be relatively thick from the
recent repair. There is also a small area at the southeast corner of the westernmost cell
where waste is estimated to be relatively shallow.
4.0 Comparison of 2019 and 2021 Geophysical Results
Quantitative comparisons of the 2019 and 2021 EM and GPR data were completed.
Here, Geo Solutions used the GRID MATH function in Surfer version 17 to compare the
2019 and 2021 geophysical data. A weakened EM response in the area of the northern
slope repair was observed from 2019 to 2021 which is indicative of a thicker cap (i.e. the
EM profiler is farther away from the waste in 2021 thus has a weaker response). Figure 9
is a contour map of the GRID MATH comparison data of the 32,190 Hz apparent
conductivity response (2021 Data — 2019 Data = Change in EM response). The purple
areas shown on Figure 9 represent areas of a weakened EM response from 2019 to 2021.
Here, the entire area of the northern slope repair has been reduced on average by 50
mS/m. This is likely related to the increase thickness of landfill cap in this area. During
the 2019 evaluation the slope was significantly eroded and waste was visible in some
areas of the slope. Since 2019, the slope was repaired and during the time of the 2021
geophysical evaluation the cap was observed to be visually thicker with no waste exposed
at the surface (Appendix A.). Figures 10 and 11 are a cross sectional images of the
northern slope from the 2019 and 2021 GPR evaluations respectively. The 2021
evaluation shows stratified layers of landfill cap and a greater depth to the top of
suspected solid waste in the area of the slope repair. Figure 12 is a contour map of the
GRID MATH comparison data of the landfill cap thickness (2021 Cap Thickness — 2019
Cap Thickness = Change in Cap Thickness from 2019 to 2021). Here, light blue and
green hues represent mostly unchanged cap thickness while the orange and red hues
indicate areas of a thicker landfill cap. Most notable on Figure 12 is the area of the
northern slope repair. The cap thickness increased along the area of northern slope repair
by 15 to 20 inches from 2019 to 2021. Also, overall the cap thickness increased along
the slopes of the westernmost cell by approximately 10 to 12 inches.
Con

5.0 Conclusions
Electromagnetic and ground -penetrating radar evaluations were carried out as part of the
geophysical evaluation at the Southern Unit of the Pitt County Landfill, located in
Greenville, NC to document the recent landfill remediation. The objective of the
geophysical evaluation was to replicate the 2019 EM and GPR evaluations in an effort to
create a post remediation dataset for comparisons.
The EM apparent conductivity and in -phase responses were very similar compared to the
2019 evaluation except for at the location of the major slope repairs along the northern
side of the Southern Unit and slopes of the westernmost cell. This is likely related to an
increased cap thickness at the repaired slopes. The EM response to the leachate seeps
along the toe of the landfill slope are very similar to the 2019 evaluation. It is likely too
soon to see improvements at the seep locations due to very slow -moving soil pore water
and groundwater moving through the landfill.
The GPR evaluation also showed similar results to the 2019 evaluation except at the
locations of slope repair. The repaired area along the northern slope has the largest
increase in landfill cap thickness and depth to solid waste. Areas along the slope of the
westernmost cell also show improvement to cap thickness and depth to solid waste.
Overall, the geophysical results confirmed improvements were made to the landfill cap
which successfully documents the remedial efforts by the Pitt County Landfill. It will
likely take time to see improvements to the seeps along the toe of the slopes. If further
geophysical evaluations are completed at the Southern Unit, we recommend limiting the
scope to the areas of the identified seeps to monitor the effectiveness of the improved
surface drainage system and also to potential new areas of erosion where the landfill cap
may be degraded.

PROJECT NARRATIVE
Client: Groundwater Management Associates, Inc. (GR022)
Project: Pitt County Landfill - App I
Lab ID: CE10470
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 associated LCS exhibited high bias; since the result is ND, there is no impact (QL-02).
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).
Post -digestion 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).
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.
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).
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.
