1.0 INTRODUCTION
This Water Quality Monitoring Plan (WQMP) was prepared by Smith Gardner, Inc. to describe the
water quality monitoring program at the C&D Landfill, Inc. (NC Solid Waste Permits 7407-CDLF-
2001 and 7407-CDLF-2009), which is located approximately 12 miles east of Uptown Greenville at
802 Recycling Lane High Point, North Carolina. The facility contains two active, unlined
construction & demolition (C&D) landfill units. The Facility was developed in two non-contiguous
footprints, Phases 1 and 2 approximately midway between US 264, i.e., a localized topographic
divide, and Grindle Creek. The phases became operational in May 2001 and August 2009,
respectively. Phase 1 was the regional repository for flood -damage debris after Hurricane Floyd
in 1999. Phase 2 was a staging area, where flood -debris was stored temporarily. Both areas were
used for agriculture, and a former railroad corridor traverses the site, including the northern
Phase 2 footprint. A permit to begin construction on Phase 3 is currently being drafted. Upon
approval, Phase 3 will also be included under this Water Quality Monitoring Plan. This plan
describes the necessary procedures to satisfy North Carolina Solid Waste Management Rule 15A
NCAC 1313.0544 (b) and (c). The WQMP addresses two major elements; groundwater system
monitoring/sampling and surface water monitoring/sampling.
The WQMP is designed to meet the following requirements:
• Represent the quality of the background groundwater that has not been affected by
leakage from the unit f.0544IbJf1JIAJJ.
• Represent the quality of the groundwater passing the relevant point of compliance as
approved by the Division f 0544 IblflJfBJJ.
• The groundwater monitoring programs must include consistent sampling and analysis
procedures that are designed to ensure monitoring results that provide an accurate
representation of groundwater quality at the background and down -gradient wells f.0544
WMICJJ.
• Detection groundwater monitoring program t.0544 fbJl lJIDJJ.
• The sampling procedures and frequency must be protective of human health and the
environment f.0544IbJf1J(EJJ.
• Responsibility of sample collection and analysis must be defined as a part of the
monitoring plan f.0544 fcJf2JJ.

1.2 Existing Site Conditions
The facility is located approximately twelve miles east of downtown Greenville on US-264
E. Area development is mixed agricultural, industrial, and rural residential.
The permitted facility is bordered to the north by US-264 E. and to the south by Grindle
Creek. A mix of wooded marshlands and agricultural lands border the eastern and
western boundaries of the facility. Grindle Creek and smaller streams create a natural
barrier to LFG migration to the south and west.

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
Ground surface elevations range from approximately El. 16 (feet above mean sea level)
along Grindle Creek to El. 120 at the top of the Phase 2B cell. The facility location and
existing conditions are shown on Figure 1.
1.2.1 Site Geology
Historical literature and available geologic maps indicate that C&D Landfill, Inc.
sits within the NC Coastal Plain. The coastal plain is characterized as an
eastward thickening wedge of sedimentary layers that alternate between sandy
aquifers an aquitards. Information taken from The Geologic Map of North
Carolina, 1985 shows that the C&D landfill is underlain by the Yorktown
Formation, which is described as "fossillifferous clay with varying amounts of
fine-grained sand, silty sand, sandy silt, silty clay, and blueish gray shell
material".
1.2.2 Site Hydrogeology
Groundwater in the upper -most aquifer generally flows through unconsolidated
sediments Recharge occurs generally in the northern portion of the site and is
Limited on slopes. Groundwater flows generally south where it discharges into
Grindle Creek. The groundwater potentiometric surface generally reflects a
subdued expression of the surface topography. Local conditions are considered
typical for the coastal plain region.

2.3 Groundwater Samole Collection
This section presents details of the procedures and equipment required to perform
groundwater field measurements and sampling from monitoring wells during each
monitoring event. Where possible, sampling will proceed from the upgradient
(background) wells to downgradient (compliance) wells or, when data is available,
from least to most contaminated.
2.3.1 Monitorino Conditions and Observations
The following measurements will be recorded in a dedicated field logbook prior
to sample collection:
• Depth to static water level and well bottom (to the nearest 0.01 foot);
• Water column height in the riser (based on measured well depth);
• Condition of monitoring well (well locks, steel casing, concrete pad, etc.);
and
• Monitoring location conditions, including access and surroundings.
Report to the Owner/Operator any observed maintenance or access issues
observed.
Documentation of all field activities will be in accordance with Section 6.1.
2.3.2 Fuel Powered Equipment
Fuel -powered equipment, such as generators or compressors for pumps, must
be situated away and downwind from sampling activities. If field conditions
prevent such placement, then the fuel source must be placed as far away as
possible from the sampling activities. Sampling conditions must be described in
detail in the field notes.
If fuel must be handled, it should be done the day before sampling. Effort should
be made to avoid handling fuels on the day of sampling. If fuels must be
dispensed during sampling activities, dispense fuel downwind and well away
from any sampling locations. Wear gloves while working with fuel and dispose of
the gloves away from sampling activities. Wash hands thoroughly after handling
any fuels.
2.3.3 Equipment Decontamination
Non -dedicated equipment that may come in contact with the well casing and
water will be decontaminated between wells. The procedure for
decontaminating non -dedicated equipment is as follows:
1. Don new powder -free gloves.
EJE Recycling D Disposal, Inc. Water Quality Monitoring Plan
March 2022 Page 7

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
2. Clean item with tap water and phosphate -free laboratory detergent
(Liqui-Nox or equivalent) using a brush if necessary to remove particulate
matter and surface films.
3. Rinse thoroughly with pesticide grade isopropanol and allow to air dry.
4. Rinse with organic -free water (Milli-Q water or other ultra -pure water)
and allow to air dry.
5. Wrap with commercial -grade aluminum foil, if necessary, to prevent
equipment contamination during storage or transport.
Liqui-Nox detergent solutions should be stored in a clearly marked High -Density
Polyethylene (HDPE) or Polypropylene (PP) container. Containers for pesticide -
grade isopropanol will be made of inert materials such as Teflon, stainless steel,
or glass.
Using dedicated sampling equipment or new disposable Teflon bailers at each
well should minimize the need for decontamination in the field. Unclean
equipment will be segregated from clean equipment during field activities. Clean
equipment will remain in the manufacturer's packaging until use, or will be
wrapped in commercial -grade aluminum foil or untreated butcher paper.
2.3.4 Water Level Measurements
2.3.4.1 Static Water Levels
Static water level and depth to the well bottom will be measured in each
well prior to purging or sampling activities. Static water level and well
depth measurements are necessary to calculate the static water volume
in the well prior to purging. Additionally, these measurements provide a
field check on well integrity, degree of siltation, and are used to prepare
potentiometric maps, calculate aquifer flow velocities, and monitor
changes in site hydrogeologic conditions.
Groundwater depths will be measured to a vertical accuracy of 0.01 feet
relative to established wellhead elevations. Each well will have a
permanent, easily identified reference point, established by a Registered
Land Surveyor on the well riser lip from where measurements will be
gauged.

March 2022 Page 8

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
2.3.4.2 Contamination Prevention
New, powder -free, surgical gloves will be donned for each sampling
location. Appropriate measures will be implemented during
measurement activities to minimize the potential for soils,
decontamination supplies, precipitation, and other potential contaminants
from entering the well or contacting clean equipment.
2.3.4.3 Equipment
An electronic water level indicator, constructed of inert materials, such
as stainless steel and Teflon, will be used to measure depth to
groundwater in each well and/or piezometer. Between each well, the
device will be thoroughly decontaminated by washing with non -
phosphate (Liqui-Nox) soap and rinsing with organic -free water to
prevent cross contamination from one well to another.
2.3.5 Monitorinil Well Evacuations
Water accumulated in each well may be stagnant and unrepresentative of
surrounding aquifer conditions. Therefore, this water must be removed to insure
that fresh formation water is sampled. Following static water level
measurement the standing water in the well casing will be purged. Monitoring
well evacuation should be performed in up -gradient wells first systematically
moving to down -gradient well locations.
2.3.5.1 Contamination Prevention
New, powder -free, surgical gloves will be donned for well purging and
sampling activities and whenever handling decontaminated field
equipment. Appropriate procedures during measurement, purging, and
sampling activities will be used to minimize the potential for surface soils,
decontaminated supplies, precipitation, and/or other potential
contaminants from entering the well or contacting cleaned equipment.
2.3.5.2 Calculations
The standing water volume in the well riser and screen will be calculated
immediately before well evacuation during each monitoring event if
standard purging techniques are utilized. A standing water volume will
be calculated for each well using measured static water level, well depth,
and well casing diameter according to the following equation:

where
2.3.5.3 Well Purging
V— (TD-SWL)C
V = one well volume (gallons)
TD = total well depth (feet)
SWL = static water level (feet)
C = volume constant for given well diameter
(gallons/ft)
C = 0.163 gallons/ft for two-inch wells
C = 0.653 gallons/ft for four -inch wells
Equipment
Several options for well purging may be used at this site including:
Disposable Bailers;
Low Flow Pumps; and
Grundfos Redi-Flo Pumps.
Disposable Bailers: Where bailers are used, new, disposable bailers
with either double or bottom check -valves will be used to purge each
well. Disposable purge bailers will be constructed of fluorocarbon resin
(Teflon) or inert plastic suitable for the well and ground conditions. Each
bailer will be factory -cleaned and remain sealed in a plastic sleeve until
use. A new Teflon -coated stainless steel, inert mono -filament line or
nylon cord will be used for each well to retrieve the bailers. Where
bailers are used, a minimum of three well volumes will be purged unless
the well runs dry.
HydraSleeveTM: Where elevated turbidities and suspended solids are an
issue, HydraSleeve (or equivalent) technology may be used. This is a no -
purge technology which allows capture of a sample through a top filling
and top pouring weighted sleeve. The HydraSleeve "Speedbag" can be
used for multiple sample aliquot collections in one well. Only new,
dedicated HydraSleeves may be used at each well location.
Low Flow Pumps: Monitoring wells may be purged and sampled using
the low -flow sampling method in accordance with DWM guidance
( "Groundwater, Surface Water, and Soil Sampling for Landfills "" (N C D EQ,
2008)).
Grundfos Redi-Flo Pumps: Where Redi-Flo pumps are used, the same
low flow techniques for sampling will be used. See above for a
purging/sampling technique summary.

March 2022 Page 10

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
Technique
Depth -to -water measurements will be obtained using an electronic water
Level indicator capable of recording the depth to an accuracy of 0.01 foot
(see Section 2.3.4). A determination of whether or not the water table is
Located within the screened interval of the well will be made. If the water
table is not within the screened interval, the amount of drawdown that
can be achieved before the screen is intersected will be calculated. If the
water table is within the screened interval, total drawdown should not
exceed 1 foot to minimize the aeration and turbidity. If the water table is
above the screened interval, the drawdown amount should be minimized
to keep the screen from being exposed.
If the purging equipment is non -dedicated, the equipment will be lowered
into the well, taking care to minimize the water column disturbance. If
conditions (i.e., water column height and well yield) allow, the pump will
be placed in the uppermost portion of the water column (minimum of 18
inches of pump submergence is recommended).
The minimum volume/time period for obtaining independent Water
Quality Parameter Measurements (WQPM) will be determined based on
the stabilized flow rate and the volume in the pump and the discharge
tubing. The bladder pump volume should be obtained from the
manufacturer. Alternately, if a continuous read flow -cell is used, it can
indicate when WQPM should be obtained, as long as the purged volume is
equal to or greater than the calculated volume. Discharge tubing
volumes are as follows:
3/8-inch inside diameter tubing: 20 milliliters per foot
1/4-inch inside diameter tubing: 10 milliliters per foot
3/1 6-inch inside diameter tubing: 5 milliliters per foot
Begin the well purge following calculations to determine the volume of
the flow -cell or the pump and the discharge tubing. The flow rate should
be based on historical data for each individual well (if available) and
should not exceed 500 milliliters per minute. The initial round of WQPM
should be recorded and the flow rate adjusted until drawdown in the well
stabilizes. Water levels should be measured periodically to maintain a
stabilized water level. The water level should not fall within one foot of
the top of the well screen. If the purge rate has been reduced to 100
milliliters or less and the head level in the well continues to decline, the
required water samples should be collected following WQPM
stabilization, based on the criteria presented below.
If neither the head level nor the WQPM stabilize, a passive sample should
be collected. Passive sampling is defined as sampling before WQMP have
stabilized if the well yield is low enough that the well will purge dry at the
lowest possible purge rate (generally 100 milliliters per minute or less).

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
WQPM stabilization is defined as: pH (+/- 0.2 S.U.), conductance (+/- 5%
of reading), temperature (+/- 10% of reading or 0.2°C), and dissolved
oxygen (DO) [+/- 20% of reading or 0.2 mg/L (whichever is greater)].
Oxidation reduction potential (ORP) will be measured and ideally should
also fall within +/- 10mV of reading; however, this is not a required
parameter. At a minimum, turbidity measurements should also be
recorded at the beginning of purging, following WQPM stabilization, and
following sample collection. The optimal turbidity range for micropurging
is 25 Nephelometric Turbidity Units (NTU) or less. Turbidity
measurements above 25 NTU are generally indicative of an excessive
purge rate or natural conditions related to excessive fines in the aquifer
matrix.
WQPM stabilization should occur in most wells within five to six rounds of
measurements. If stabilization does not occur following the removal of a
purge volume equal to three well volumes, a passive sample will be
collected.
The direct -reading equipment used at each well will be calibrated in the
field according to the manufacturer's specifications prior to each day's
use and checked, at a minimum, at the end of each sampling day.
Calibration information should be documented in the instrument's
calibration logbook and field logbook/notes.
Each well is to be sampled immediately following WQPM stabilization.
The sampling flow rate must be maintained at a rate less than or equal to
the purging rate. For volatile organic compounds, lower sampling rates
(100 - 200 milliliters/minute) should be used. Final field parameter
readings should be recorded prior to and after sampling.
2.3.5.4 Purge Rate
Wells will be purged at a rate that will not cause recharge water to be
excessively agitated or cascade through the screen. Care will be taken to
minimize disturbance to the well sidewalls and bottom that could result
in the silt and fine particulate matter becoming suspended. The purged
water volume from each well and the relative recharge rate will be
documented in sampling field notes/book. Wells which have very low
recharge rates will be purged once until dry. Damaged, dry, or low
yielding and high turbidity wells will be documented for reconsideration
before the next sampling event.

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
2.3.5.5 Purge Water Disposal
Purge water will be managed to prevent possible soil and surface water
contamination. Well site management options may include temporary
containment and disposal as leachate or portable activated carbon
filtration if warranted by field characteristics.
2.3.5.6 Non -Dedicated Equipment
Durable, non -dedicated equipment lowered into the well or that may
come in contact with the water samples, will be disassembled to the
degree practical and decontaminated before each use. Equipment
decontamination procedures are described in Section 2.3.3.
2.3.6 Sample Collection
After purging, groundwater samples will be collected for laboratory analysis. As
much as practical, samples should be collected from least contaminated
location(s) first, followed by locations of increasing contamination across the
site. Prior to sample collection, sample labels should be properly filled -out with
permanent ink (such as Sharpie Pen). At a minimum, the label should identify
the sample with the following information:
• Site Name;
• Sample Location or Well Number;
• Date and Time of Collection;
• Analysis Required;
• Sampler's Initials;
• Preservative Used (if any); and
• Other Pertinent Information, as Necessary.
Completed sample labels should be affixed to the sample bottle prior to
sampling.
Sampling will occur within 24-hours of well purging and as soon after well
recovery as possible. Wells which fail to recharge or produce an adequate
sample volume within 24 hours of purging will not be sampled.
2.3.6.1 Field Parameters
Field measurements to determine temperature, pH, and specific
conductivity will be recorded immediately prior to sampling each
monitoring location. Turbidity measurements may be collected for
metals evaluation. The field test specimens will be collected with the
sampling bailer and placed in a clean, non-conductive glass or plastic
container for observation. Temperature, pH, conductivity, and turbidity
EJE Recycling D Disposal, Inc. Water Quality Monitoring Plan
March 2022 Page 13

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
meter calibration will be performed according to the manufacturers'
specifications and consistent with Test Methods for Evaluating Solid
Waste -Physical/Chemical Methods (SW-846). A pocket thermometer and
litmus paper will be available in case of meter malfunction.
2.3.6.2 Sample Equipment
Several options for sample collection are available for this site including:
Disposable Bailers;
Low Flow Pumps; and
Grundfos Redi-Flo Pumps.
These are each discussed in greater detail below.
Disposable Bailers: Where bailers are used, each well will be sampled
using a new, factory -cleaned, disposable Teflon bailer with bottom check -
valve and sample discharge mechanism. A new segment of Teflon -
coated stainless steel wire, inert mono -filament line or nylon cord will be
used to lower and retrieve each bailer. The bailer will be lowered into
each well to the point of groundwater contact and then allowed to fill as it
sinks below the water table. Bottom contact will be avoided in order to
avoid suspending sediment in the samples. The bailer will be retrieved
and emptied in a manner which minimizes sample agitation.
Low Flow Pumps: Following purging with the low flow pump systems,
samples may be collected immediately from the pumping system.
Samples are to be collected in the order outlined in Section 2.3.6.4.
Grundfos Redi-Flo Pumps: Following purging of three well volumes,
samples may be collected from the Redi-Flo pumps. Samples will be
collected in the order outlined in Section 2.3.6.4.
2.3.6.3 Sample Transference
Samples will be transferred directly from the disposable bailer or pump
discharge tubing into a sample container that has been specifically
prepared for the preservation and storage of compatible parameters. A
bottom emptying device provided will be used to transfer samples from
bailer to sample container. The generation air bubbles and sample
agitation will be minimized during bailer discharge.

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
2.3.6.4 Sample Collection Order
Groundwater samples will be collected in the order of volatilization
sensitivity. When collected, the following sampling order will be
observed:
• Volatile Organics and Volatile Inorganics;
• Extractable Organics, Petroleum Hydrocarbons, Aggregate
Organics, and Oil and Grease;
• Total Metals;
• Inorganic Nonmetallics, Physical and Aggregate Properties, and
Biologicals;
• Microbiological; and
• Other Parameters (as applicable).
Note: if the pump used to collect groundwater samples is not suitable to
collect volatile or extractable organics then collect other parameters and
withdraw the pump and tubing, then collect the volatile and extractable
organics.
Samples will be collected and analyzed in an unfiltered state. Dissolved
metal analysis samples, if subsequently required, will be prepared by
field filtration using a decontaminated peristaltic pump and a disposable
0.45 micron filter cartridge specifically manufactured for this purpose.
2.3.6.5 Decontamination
Reusable sampling equipment including water level probes, water quality
meters, interface probes, and filtering pumps which might contact aquifer
water or samples will be thoroughly decontaminated between wells by
washing with non -phosphate soapy, organic free water (Milli-O or
equivalent) and rinsing with isopropanol and organic -free water.
Equipment decontamination procedures are detailed in Section 2.3.2.
2.3.6.6 Sample Preservation
Following sampling at each location, the sample bottles will be placed in
a cooler with ice for preservation.
2.3.6.? Field Quality Assurance
Blank samples will be prepared, handled, and analyzed as groundwater
samples to ensure cross -contamination has not occurred. One set of trip
blanks, as described in Section 3.1.1, will be prepared before leaving the
laboratory to ensure that the sample containers or handling processes
have not affected the sample quality. One set of equipment blanks will be
EJE Recycling D Disposal, Inc. Water Quality Monitoring Plan
March 2022 Page 15

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
created in the field at the time of sampling to ensure that the field
conditions, equipment, and handling during sampling collection have not
affected the sample quality. Equipment blanks are discussed in Section
3.1.2. A duplicate groundwater sample may be collected from a single
well as a laboratory accuracy check. Blanks and duplicate containers,
preservatives, handling, and transport procedures for surface water
samples will be identical to those described for groundwater samples.
2.3.6.8 Sample Containers
Sample containers will be provided by the laboratory for each sampling
event. Containers must be either new, factory -certified analytically clean
by the manufacturer, or cleaned by the laboratory prior to shipment for
sampling. Laboratory cleaning methods will be based on the bottle type
and analyte of interest. Metal containers are thoroughly washed with
non -phosphate detergent and tap water and rinsed with (1:1) nitric acid,
tap water, (1:1) hydrochloric acid, tap water, and non -organic water, in
that order. Organic sample containers are thoroughly washed with non -
phosphate detergent in hot water and rinsed with tap water, distilled
water, acetone, and pesticide quality hexane, in that order. Other sample
containers are thoroughly washed with non -phosphate detergent and tap
water, and rinsed with tap water and non -organic water. The laboratory
will provide proper preservatives in the sample containers prior to
shipment (see Section 4.01.
2.4 Surface Water Sample Collection
This section presents the procedures and equipment required to perform surface water
field measurements and sampling from springs, streams, and ponds during each
monitoring event.
2.4.1 MonitorinO Conditions and Observations
Surface water quality analyses are particularly sensitive to site hydrologic
conditions and recent precipitation events. Water levels may fluctuate
significantly in comparison the groundwater table and may result in either
diluting or increasing contaminant loadings. Sampling event scheduling and the
interpreted surface water data should account for recent weather and sampling
station conditions.
Surface water level and sampling station conditions should be recorded during
each sampling event. Surface water observations will include the flood stage in
streams, seasonal base flow conditions and confirm location and timing for
meaningful surface water quality sampling. The following objective observations
will be recorded in a dedicated field logbook prior to sample collection:
EJE Recycling D Disposal, Inc. Water Quality Monitoring Plan
March 2022 Page 16

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
• Relative stream water level;
• Surface water clarity; and
• Monitoring location conditions, including access and surroundings.
Report to the Owner/Operator any observed maintenance or access issues
observed.
2.4.2 Sampling Station Modifications
Modifications to surface water sampling station conditions may be required prior
to each sampling event. These modifications may include surface and submerged
debris removal, slightly deepening the station to allow sample container
immersion, or channeling/piping to consolidate local discharge. When
modifications are necessary, sufficient time will be allowed for settlement of
suspended solids between the disturbance and sample collection. A minimum
four hour settling period will be observed.
2.4.3 Sample Collection
2.4.3.1 Collection Procedure
Surface water samples will be obtained from locations with minimal
turbulence and aeration. For stream sampling locations, samples will be
collected if flowing water is observed during the sampling event. For
pond sampling locations, water flow is not necessary. New, powder -free,
surgical gloves will be donned prior to sample collection. The following
procedure will be followed when conducting surface water sampling:
1. Put on new, powder -free, surgical gloves.
2. Hold the bottle by the bottom with one hand and remove the cap
with the other.
Push the sample container slowly into the water with the mouth
tilted up toward the current to fill. A water depth of six inches is
generally satisfactory. Breaching the surface or losing sample
preservatives while filling the container will be avoided.
4. If there is little current movement, the container should be moved
slowly, in a lateral, side to side direction, with the container mouth
pointing upstream.
2.4.3.2 Field Parameters
Temperature, pH, specific conductivity, and turbidity will be measured
prior to sampling to assess field conditions and check the water sample
EJE Recycling D Disposal, Inc. Water Quality Monitoring Plan
March 2022 Page 17

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
stability over time. Temperature, pH, specific conductivity, and turbidity
measurements will be recorded for surface water samples.
Temperature, pH, conductivity and turbidity meters will be calibrated at
the beginning of each sampling event, according to the manufacturers'
specifications and consistent with Test Methods for Evaluating Solid
Waste - Physical/Chemical Methods (SW-846).
2.4.3.3 Sample Collection Order
Surface water samples will be collected in the order of parameter
volatilization sensitivity. The following order will be observed:
• Volatile Organics and Volatile Inorganics;
• Extractable Organics, Petroleum Hydrocarbons, Aggregate
Organics, and Oil and Grease;
• Total Metals;
• Inorganic Nonmetallics, Physical and Aggregate Properties, and
Biologicals;
• Microbiological; and
• Other Parameters (as applicable).
Samples will be collected and analyzed in an unfiltered state. Dissolved
metal analysis samples, if subsequently required, will be prepared by
field filtration using a decontaminated peristaltic pump and a disposable
0.45 micron filter cartridge specifically manufactured for this purpose.
Additional blanks and duplicate samples will not be collected with the
surface water samples.
2.4.3.4 Decontamination
Field meters which might contact surface water samples will be
decontaminated between stations Equipment decontamination
procedures are detailed in Section 2.3.3.
2.4.3.5 Sample Preservation
Following sampling at each location, the sample bottles will be placed in
a cooler with ice for preservation.
2.4.3.6 Sample Containers
Sample containers will be provided by the laboratory for each surface
water sampling event. Each container's preparation and preservatives
will be the same as those utilized for groundwater sampling and
addressed previously in Section 2.3.6.8.

3.0 FIELD QA/QC PROGRAM
Field Quality Assurance/Quality Control (QA/QC) requires the routine collection and analysis of
blanks to verify that the handling process has not affected the sample quality. Contaminants
found in the trip blanks could be attributed to:
1. Interaction between the sample and the container;
2. Contaminated source water; or
3. A handling procedure that alters the sample.
3.1 Blank Samples
3.1.1 Trip Blanks
The laboratory will prepare a trip blank by filling each sample bottle type with
laboratory grade distilled or deionized water. Trip blanks will use the specific
bottle type required for the analyzed parameters from a bottle pack specifically
assembled by the laboratory for each sampling event. Trip blanks are assembled
in the laboratory, transported with the empty bottle packs, remain in the coolers
throughout sampling, and are transported back to the laboratory for analysis.
Trip blanks will only be analyzed for volatile and purgeable organics.
3.1.2 Eauiament Blanks
Where wells are sampled with non -dedicated equipment, equipment blank
samples will be collected at a rate of one sample per day. To collect an
equipment blank, pour non -organic (Milli-Q or equivalent) water into a bailer and,
handling the bailer in a manner identical to well sampling, transfer the water into
the specified "blank" sample collection jars specified. Equipment blank samples
are packed and sent to the laboratory with the other samples.
3.1.3 Field Blanks
As deemed necessary, field blanks will be collected. The laboratory will provide
designated bottles with laboratory grade distilled or deionized water. The water
will be poured from one laboratory provided container to an empty laboratory
provided container for the specified analysis. This activity must be performed at
the sampling location. Field blank samples will be packed in the cooler and sent
to the laboratory with the other samples.

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
3.1.4 Blank Concentrations
The contaminant concentration levels found in the blanks will be reported but
will not be used to correct groundwater data. In the event that elevated
parameter concentrations are found in a blank, the analysis will be flagged for
future evaluation and possible re -sampling.
3.1.5 Field Instruments
Field instruments utilized to measure groundwater characteristics will be
calibrated prior to entering the field and recalibrated in the field as required to
insure accurate measurements for each sample. The specific conductivity and
pH meter will be recalibrated utilizing two prepared solutions of known pH
concentrations in the anticipated value range (between 4 and 10). A permanent
thermometer, calibrated against a National Bureau of Standards Certified
thermometer, will be used for temperature meter calibration. Other field
equipment should be calibrated at least daily using the manufacturer's
recommended specifications.

4.0 SAMPLE PRESERVATION AND SHIPMENT
Sample preservation methods, shipment, and Chain -of -Custody procedures observed between
sampling and laboratory analysis are presented in this section.
4.1 Sample Preservation
Pre -measured chemical preservatives will be provided by the analytical laboratory.
Hydrochloric acid will be used as a chemical stabilizer and preservative for volatile and
purgeable organic specimens. Nitric acid will be used as the preservative for analysis of
inorganic metals constituents.
4.2 Storage/Transport Conditions
Proper storage and transport conditions must be maintained to preserve sample
integrity between collection and analysis. Ice and chemical cold packs will be used to
cool and preserve samples, as directed by the analytical laboratory. Samples will be
maintained at a maximum temperature of 4° C. Dry ice is not to be used. Samples will
be packed and/or wrapped in plastic bubble wrap to inhibit breakage or accidental spills.
Chain -of -Custody control documents will be placed in a waterproof pouch and sealed
inside the cooler with the samples for shipping. Tape and/or custody seals will be
placed on the outside of the shipping coolers, in a manner to prevent and detect
tampering with the samples.
4.3 Sample Delivery
Samples will be delivered to the analytical laboratory within a reasonable time period in
person or using an overnight delivery service to insure holding time compliance. If
samples are not shipped the same day, the ice used to keep the samples cool will be
replenished to maintain the required maximum 4° C temperature. Sample shipment and
delivery will be coordinated with the laboratory. Do NOT store or ship highly
contaminated samples (concentrated wastes, free product, etc.) or samples
suspected of containing high contaminant concentrations in the same cooler or
shipping container with other environmental samples.
4.4 Chain of Custody
Chain -of -Custody control will be maintained from sampling through analysis to prevent
tampering with analytical specimens. Chain -of -Custody control procedures consist of
the following:
EJE Recycling D Disposal, Inc. Water Quality Monitoring Plan
March 2022 Page 21

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
Chain -of -Custody will originate at the laboratory with the shipment of prepared
sample bottles and a sealed trip blank(s) in sealed coolers. Identical container
kits will be shipped by express carrier to the sampler or site or will be picked up
at the laboratory.
2. After sample kit delivery but prior to sampling, the sampler will inventory the
container kit checking consistency between the number and type of containers
present with what is indicated in the Chain -of -Custody forms and that required
for the sampling event.
Labels for individual sample containers will be written in the field, indicating the
site name, sample location/well number, date and time of sample collection,
analysis required, sampler's initials, and preservation methods used for the
sample.
4. Collected specimens will be placed in the coolers on ice and will remain in the
continuous possession of the field technician until shipment or transferal as
provided by the Chain -of -Custody form has occurred. If continuous possession
cannot be maintained by the field technician, the coolers will be temporarily
sealed and placed in a secure area.
Once delivered to the laboratory, samples will be issued laboratory sample numbers
recorded into a logbook indicating client, sample location/well number, and delivery
date and time. The laboratory director or his designee will sign the Chain -of -Custody
control forms and formally receive the samples.
Submitted Chain -of -Custody form copies will be placed in the laboratory's analytical
project file and attached to the laboratory analysis report.
Chain -of -Custody forms will be used to transfer direct deliveries from the sampler to
the laboratory. A coded, express delivery shipping bill shall constitute the Chain -of
Custody between the sampler and laboratory for overnight courier deliveries.

5.o LABORATORY ANALYSIS
The samples will be analyzed for the parameters specified for detection and assessment
monitoring purposes including water quality field indicators (pH, conductivity, temperature, and
turbidity) and those constituents listed in Table 2. Analytical methods from Test Methods For
Evaluating Solid Waste - Physical/Chemical Methods (SW-846) or Methods For the Chemical
Analysis of Water and Wastes will be consistent with the DWM's policies regarding analytical
methods and reporting limits. Analysis will be performed by a laboratory certified by the DWM
for the analyzed parameters.
5.1 Laboratory Quality Assurance/Quality Control
As stated above laboratory analysis will be performed by a NC Certified laboratory.
Formal environmental laboratory Quality Assurance/Quality Control (QA/QC) procedures
are to be utilized at all times. The laboratory must have a QA/QC program based on
specific routine procedures outlined in a written laboratory Quality Assurance/Quality
Control Manual. Internal quality control checks shall be undertaken regularly by the lab
to assess the precision and accuracy of analytical procedures.
5.2 Data Review
During analyses, quality control data and sample data shall be reviewed by the
laboratory manager to identify questionable data and determine if the necessary QA/QC
requirements are being followed. If a portion of the lab work is subcontracted, it is the
contracted laboratories responsibility to verify the subcontracted work is performed by
certified laboratories, using identical QA/QC procedures.

documenting important information pertaining to the technician's field activities. The
field logbook will document the following:
• Site Name and Location;
• Sampling Date and Time;
• Climatic Conditions During Sampling Event;
• Sampling Location/Well Identification Number; and
• Signature of Field Technician.
Groundwater Sampling Observations
• Static Water Level and Well Bottom;
• Water Column Height;
• Condition of Monitoring Well;
• Monitoring Location Conditions, Including Access and Surroundings;
• Purged Water Volume and Relative Recharge Rate (High or Low);

Ki
V=—
n
where: V = velocity (feet/day)
K = hydraulic conductivity (feet/day)
i = hydraulic gradient (feet/feet)
n = effective porosity of aquifer soils (unitless)
This evaluation will be used to determine if modifications to the WQMP may be required
(see Section 7.11.
6.3 Reporting
A report summarizing the monitoring event and the analytical data from the event will be
submitted to the DWM within 120 days of completion of the event.
Monitoring reports will include the following:
1. A discussion of site geology and hydrogeology;
2. A discussion of the monitoring event procedures and results;
3. A groundwater flow evaluation (including a potentiometric surface map);
4. Analytical laboratory reports and summary tables;
5. Graphical and/or statistical analysis of analytical data may be reported but is not

DocuSign Envelope ID: 2E4DB082-8257-4B2E-BAEB-71AC7B5D4A6E
7.o MONITORING PROGRAM MODIFICATIONS
This section addresses the procedures that should be followed with respect to water quality
monitoring program modifications.
7.1 Plan Modifications and Uadates
After each water quality monitoring event, a groundwater flow evaluation will be
performed to determine the groundwater flow rate and direction at the site (see Section
6.2). If this evaluation reveals the monitoring network is insufficient to monitor for a
potential release of solid waste constituents from the solid waste management area, a
modified plan will be prepared and submitted to the DWM for approval.
The need for plan modifications and updates will also be determined as part of regularly
scheduled permitting activities for the facility.
7.2 Well Abandonment/Rehabilitation
Should wells become irreversibly damaged or require rehabilitation, the DWM will be
notified. If monitoring wells and/or piezometers are damaged irreversibly they will be
abandoned under DWM direction following 15A NCAC 02C .0113. The abandonment
procedure in unconsolidated materials involves over -drilling and/or pulling the well
casing and plugging the well with a sealant such as neat cement grout and/or bentonite
clay. For bedrock well completions, the abandonment encompasses plugging the
interior well riser and screen with a sealant such as neat cement grout and/or bentonite
clay.
7.3 Additional Well Installations
Additional well installations will be carried out in accordance with DWM directives.
Monitoring wells will be installed under the supervision of a geologist or engineer who is
registered in North Carolina and who will certify to the DWM that the installation
complies with the North Carolina rules and regulations. For future well installations, the
documentation for well construction will be submitted by the registered geologist or
engineer to the DWM within sixty (60) days after well construction.
7.4 Imolementation Schedule
The monitoring program proposed herein will be implemented following approval of this
Water Quality Monitoring Plan by the DWM.
