1 Introduction and Purpose
This document provides the Water Quality Monitoring Plan (WQMP) Revision 1 for the Duke Energy Dan
River Steam Station Landfill Development and is intended to satisfy the requirements of North Carolina
Administrative Code (NCAC) Title 15A NCAC 13B .0504(1)(g)(iv). The purpose of this revised document
is to confirm actual procedures used during the well installation process for leachate monitoring and for
monitoring the quality of the groundwater in the shallow unconfined uppermost and lower bedrock aquifer
underlying the landfill and surface water adjacent to the landfill during operation and post closure periods.
The revised WQMP (hereafter referred to as the WQMP) consists of a series of wells placed upgradient,
downgradient, and side-gradient of the Dan River Landfill to monitor both background concentrations of
constituents of interest (COIs) potentially associated with coal combustion residuals (CCRs) or coal ash
scheduled to be placed in the landfill.
The WQMP is designed to provide information to the North Carolina Department of Environmental Quality
(NCDEQ) - Solid Waste Section (SWS) and the landfill owner and operations personnel for the purpose of
evaluating potential impacts to groundwater and surface water quality prior to, during, and after landfilling
operations are completed.
1.1 Project Description
The Dan River Landfill is located on Dan River Steam Station property to store existing coal combustion
residuals (CCRs) from four units on site. The units consist of the Primary Ash Basin, Secondary Ash
Basin, and two unlined ash structural fills (Ash Fills 1 and 2). Electricity production from coal combustion
ceased on April 1, 2012 and the coal-fired plant has been decommissioned; therefore, no new coal
combustion residuals (CCRs) are currently being generated at Dan River Steam Station. A combined
cycle plant on station property currently produces electricity from natural gas.
The landfill is being constructed to facilitate placement of ash from existing on-site ash units in a lined
facility by August 1, 2019 as required by the North Carolina Coal Ash Management Act of 2014. Prior to
construction of the on-site landfill, Duke Energy removed some of the on-site ash by rail to the
Maplewood Landfill in Jetersville, Virginia.
1.2 Site Description
The Dan River Steam Station is located at 900 South Edgewood Road in Eden, Rockingham County,
North Carolina. The landfill is located largely within the historical footprint of Ash Fill 1 on the
northeastern end of the property. The landfill will consist of three cells with a total limit of waste area of
approximately 23.3 acres and accept CCR material generated during closure of the existing on-site
Primary and Secondary Ash Basins, and Ash Fills 1 and 2. The landfill includes a liner system that
provides three geosynthetic barrier components (two geomembranes and a geosynthetic clay liner) and a
soil barrier component for a total of four barrier components between waste and groundwater. The ash
within Ash Fill 1 is in the process of being removed during construction of the landfill. The landfill is bound
by existing overhead electrical lines to the west and north, rail lines to the east, and a natural gas pipeline
to the south.
1.3 Site Geology and Hydrogeology
As described in the respective Hydrogeologic Study prepared by Amec Foster Wheeler, the site is located
in the Piedmont Province of North Carolina, and more specifically, lies within a Triassic Period rift basin
containing primarily sedimentary rock sequences. Groundwater flow at the site is typical of the Piedmont
Province two-part system of regolith and bedrock as described in the site’s Hydrogeology Study (Amec
Foster Wheeler, July 15, 2015 as amended). Groundwater recharge at the site is primarily derived from
infiltration of local precipitation and groundwater levels tend to fluctuate seasonally.

The hydrostratigraphic units encountered at the site during the Hydrogeologic Study field investigations
(pre-landfill construction or operation) included soil fill, ash fill, residuum, saprolite, partially weathered

Amec Foster Wheeler Project No. 7810140065 Page 2 of 11 5/25/2017
rock (PWR), weathered/fractured bedrock, sound bedrock, and minor occurrences of alluvium. Of these
hydrostatigraphic units, groundwater was typically encountered in the PWR and saprolite units; however,
some groundwater was encountered within ash near the base of Ash Fill 1. It is anticipated that the water
level within Ash Fill 1 will subside to the underlying saprolite and PWR units once the ash is removed and
the area is lined, filled, and capped.
1.4 Well Abandonment
Observation wells and monitoring wells that exist in the vicinity of landfill construction activities and are
not included in the WQMP network, have been decommissioned or abandoned in accordance with 15A
NCAC 2C .0113 rules. Well abandonment activities occured in multiple phases to coordinate with landfill
construction activities. Well abandonment methods were selected in accordance with the following
scenarios:

• Wells within the limit of waste (LOW) of the landfill were properly abandoned by overdrilling
methods to remove well materials, and then grouted with a cement-bentonite grout. The
bentonite solids content of the grout was approximately 30% in order to provide a more flexible
grout column to accommodate extensive excavation of overburden material during landfill
construction. Tremie pipe was used to place the grout continuously from the bottom of the
borehole upwards. Well surface construction, i.e. concrete pads, protective covers and bollards
were removed.

• Wells outside the LOW but within a “cut” area of the landfill grading limits of the landfill were
properly abandoned by overdrilling methods to remove well materials, and then grouted with a
cement-bentonite grout. The bentonite solids content of the grout was approximately 30%.
Tremie pipe was used to place the grout continuously from the bottom of the borehole upwards.
Well surface construction, i.e. concrete pads, protective covers and bollards were removed.

• Wells outside the LOW but within a “fill” area of the grading limits of the landfill were properly
abandoned by in-place methods. No drilling was required for the in-place abandonment method.
The well materials remained in-place and a cement-bentonite grout was placed with tremie pipe
from the bottom of the well upwards. The bentonite solids content of the grout was approximately
5%. Well surface construction, i.e. concrete pads, protective covers and bollards were removed.

• Wells outside the LOW and grading limits of the landfill were properly abandoned by in-place
methods. The bentonite solids content of the grout was approximately 5%. Well surface
construction, i.e. concrete pads, protective covers and bollards were removed.

Within 30 days of completion of well abandonment activities, Well Abandonment Records (GW-30 forms)
were submitted to the NCDEQ. A copy of the NCDEQ Well Abandonment Record form has been
included in Appendix II.
2 Groundwater Monitoring System
2.1 Monitoring Locations
The following section describes the monitoring network for the Dan River Landfill, along with
specifications associated with installing, developing, maintaining, and decommissioning facility monitoring
wells.
2.1.1 Monitoring Network
The groundwater monitoring well network for the Dan River Landfill consists of monitoring well pairs to
monitor groundwater quality in the uppermost aquifer and the deeper bedrock aquifer at the site as shown
Water Quality Monitoring Plan Duke Energy – Dan River Steam Station
Dan River Landfill Eden, North Carolina

Amec Foster Wheeler Project No. 7810140065 Page 3 of 11 5/25/2017
on Drawing 1. Specifically, the well network consists of two (2) upgradient background compliance
monitoring well pairs (LF-BW-1S/D and LF-BW-2S/D), one (1) side-gradient well pair (LF-CW-8S/D), and
seven (7) downgradient well pairs (LF-CW-1S/D, LF-CW-2S/D, LF-CW-3S/D, LF-CW-4S/D, LF-CW-5S/D,
LF-CW-6S/D, and LF-CW-7S/D). Four (4) surface water sampling locations (SWS-1 through SWS-4)
have been established. Surface water sampling location SWS-1 is intended to serve as a background
surface water location. The well and surface water sampling locations have been selected based on the
potentiometric contours that represent site conditions as described in the Hydrogeologic Study (Amec
Foster Wheeler, December 2015). The general groundwater flow was observed to be from north to south
towards the Dan River; however, localized shallow groundwater flow discharges radially from near the
center of the site towards ephemeral or seasonal streams to the east and west of the landfill footprint as
shown on Drawing 1. Surface water flow follows topography and generally reflects surface water runoff
as a result of rainfall and recharge events as well as groundwater discharge.
The 10 groundwater monitoring well locations were chosen based on horizontal location in reference to
surface drainage features, geologic conditions, groundwater flow directions, current property boundary
and landfill features and limits.
2.1.1.1 Monitoring Wells Installed Prior to Landfill Construction
Of the 10 groundwater monitoring well pairs, one (1) well pair (LF-BW-1S/D) consists of observation
wells installed during the site’s Hydrogeologic Study. These wells were constructed in accordance with
North Carolina Well Construction Standards (15A NCAC 2C .0108) and also the North Carolina Water
Quality Monitoring Guidance Document for Solid Waste Facilities. Table 1 documents the labeling
conversions between prior observation wells and current monitoring wells.
2.1.1.2 Monitoring Wells Installed Prior to Landfill Construction
Of the 10 proposed groundwater monitoring well pairs, nine (9) well pairs (LF-CW-1S/D through LF-CW-
8S/D and LF-BW-2S/D) were installed during landfill construction at locations depicted on Drawings 1
and 2. The monitoring well pairs consist of a Type II well to monitor the uppermost aquifer and a Type III
well to monitor the deeper bedrock aquifer and were constructed in accordance with North Carolina Well
Construction Standards (15A NCAC 2C .0108) and also the North Carolina Water Quality Monitoring
Guidance Document for Solid Waste Facilities. Monitoring well construction and installation details are
provided below in Section 2.2 and typical Type II and Type III well diagrams are included as Figures 1
and 2.
2.2 Monitoring Well Construction and Installation
Each monitoring well location was constructed as Type II and Type III well pairs in accordance with the
North Carolina Well Construction Standards (15A NCAC 2C .0108) and the requirements of the North
Carolina Water Quality Monitoring Guidance Document for Solid Waste Facilities. A North Carolina
Licensed Well Driller drilled the boreholes and constructed the monitoring wells. Drilling and well
installation activities were overseen by personnel under the responsible charge of a North Carolina
Licensed Geologist . Downhole drill tooling was steam cleaned between each well location. Typical Type
II and Type III monitoring well construction details that are described in the following sections are shown
on Figures 1 and 2.

Well construction details for the monitoring wells are shown in Table 1, and respective boring and well
logs have been provided in Appendix I.

Well locations were located by a Professional Land Surveyor licensed in the state of North Carolina. Well
locations were surveyed to within 0.01 feet of horizontal and vertical. A copy of the NCDEQ Well
Construction Record form has been included in Appendix II.

Dan River Landfill Eden, North Carolina

Amec Foster Wheeler Project No. 7810140065 Page 4 of 11 5/25/2017
2.2.1 Type II (Uppermost Aquifer) Monitoring Wells
Type II wells were installed in the unconsolidated (regolith or saprolite) material of the uppermost aquifer
and boreholes were advanced using 4.25-inch I.D. hollow-stem augers and Standard Penetration Test
(SPT) sampling every five (5) feet until boring termination depth.

Type II wells consist of 2-inch Schedule 40 PVC casing and screen. Screens will be prepacked, 0.010-
inch machine-slotted, will be approximately 15 feet in length, and located where estimated long-term
seasonal high water table is slightly below the top of the screened interval. If however, groundwater is
less than five (5) feet below land surface, the top of the screen will be placed at a depth of five (5) feet
below land surface to allow adequate seal and grout. Specifically, prepacked screens consisted of
environmental grade 20/40 sand housed in a machine slotted PVC cylinder around the PVC machine-
slotted screen.

The annular space between the borehole wall and well pipe (including the prepacked screen section) from
the bottom of the borehole up to approximately two (2) feet above the top of the screen consists of
environmental grade silica sand properly sized to the formation material and screen. A one (1) to 2-foot
pelletized or granular bentonite seal was placed above the filter pack and hydrated. The remainder of the
annular space was filled with a cement/bentonite grout from the top of bentonite seal to near ground
surface.
2.2.2 Type III (Deeper Aquifer) Monitoring Wells
Type III wells were installed in partially weathered rock (PWR) or bedrock (weathered/fractured bedrock
unit or sound bedrock unit) of the deeper aquifer. Type III well boreholes were advanced through the
regolith using 8.25-inch I.D. hollow-steam augers with SPT sampling every five (5) feet until auger refusal
depth. The vertical screen positions are dictated by water bearing fractures and the formation which
dictate water bearing zones observed during the well installation process in the field.

Type III wells consist of 6-inch Schedule 40 PVC outer casing that is seated slightly into the top of
bedrock and grouted into place. Outer casing grout was allowed to cure a minimum of 48 hours prior to
remaining work being performed on the well. Next, Type III well boreholes were advanced inside and
below the outer casing using HQ coring techniques (approximate 3.7-inch diameter corehole). Screens
were prepacked, 0.010-inch machine-slotted, and approximately (five) 5 feet in length. Type III screens
were placed to intersect water-bearing fractures within the bedrock unit and have a vertical separation
distance of approximately 15 to 20 feet from its corresponding Type II well screen (distance from bottom
of Type II screen to top of Type III screen at a well pair location). Specifically, prepacked screens
consisted of environmental grade 20/40 sand housed in a machine slotted PVC cylinder around the PVC
machine-slotted screen.

The annular space between the corehole wall and well pipe (including the prepacked screen) from the
bottom of the corehole up to approximately two (2) feet above the top of the screen consists of
environmental grade silica sand properly sized to the formation material and screen. A pelletized or
granular bentonite seal, greater than 1 foot in thickness and no closer than 0.5 feet from the bottom of the
6-inch outer casing, was placed above the filter pack and hydrated. The remainder of the annular space
was filled with a cement/bentonite grout from the top of bentonite seal to near ground surface.
2.2.3 Surface Finish (Type II and Type III Monitoring Wells)
A 4-inch by 4-inch square steel or aluminum protective casing with a locking cap was placed over the well
riser pipes, extending approximately 3.5 feet above the ground surface. The protective casing was
seated into place with a 2-foot by 2-foot square concrete pad. The protective casing was painted and
provided with a permanent well tag with the following information displayed:

• Well ID number;
• Driller registration number;
Water Quality Monitoring Plan Duke Energy – Dan River Steam Station
Dan River Landfill Eden, North Carolina

Amec Foster Wheeler Project No. 7810140065 Page 5 of 11 5/25/2017
• Date of well installation;
• Total depth of well;
• Depth of screen interval;
• Depth of filter pack, seal, and grout intervals;
• Depth to groundwater following well completion; and
• Warning stating well is not for water supply and that groundwater may contain hazardous
materials.
2.2.4 Well Protection
Each monitoring well is guarded against potential damage caused by normal site activities such as
vehicle and equipment operation. Bollards are located just off the edge of the well pads at each of the
four (4) corners unless protection is provided by other means such as woods, buildings, or other
structures/features. Well pairs “share” a side of protective measures if horizontal spacing between wells
is sufficiently narrow to prevent vehicle and/or equipment access between wells. Bollard installation as a
protective measure is shown on Figures 1 and 2.
2.2.5 Surveying
A North Carolina Registered Land Surveyor located each well using State Plane coordinates, ground
surface elevation at the base of the well, and the top of the PVC inner well casing elevation. The survey
data was referenced to a site benchmark for horizontal control. Well locations were surveyed to within
0.01 feet of horizontal and vertical.
2.3 Monitoring Well Development
Following well installation, each monitoring well was developed to reduce clay, silt, sand, and other fines
which may have been introduced into the well or filter pack during installation. Well development was
performed using a submersible and/or peristaltic pump. Turbidity was monitored during development
using a field turbidity meter. Well development continued until turbidity was reduced to below 10
Nephelometric Turbidity Units (NTU). In Well LF-BW-2S, the well remained above 10 NTU after three (3)
attempts. A 1-inch prepack screen was placed inside the standard prepack screen to aid in filtration to
achieve a turbidity below 10 NTU. The 1-inch prepack consisted of an ultra fine filter sand (120 mesh),
placed between two layers of food grade plastic mesh, surrounding 0.010-inch slotted PVC.
2.4 Monitoring Well In-Situ Permeability Testing
Slug testing will be conducted to calculate hydraulic conductivity at the well location and is anticipated to
be completed in June 2017. The hydraulic conductivity values will be used in conjunction with assumed
effective porosity and horizontal groundwater gradients to estimate groundwater flow rates each
monitoring event.
2.5 Monitoring Well Maintenance
The wells and surrounding area will be maintained to provide adequate access for sampling activities,
which could include items such as vegetation control or access road maintenance. Each monitoring well
will be accessible by at least a four-wheel drive vehicle. Surface water run-on controls such as diversion
berms or channels may need to be provided to inhibit erosion or deposition at the well or damage to
concrete well pads.

In addition to access, routine maintenance of monitoring wells could include repair or replacement of well
tags, locks, well caps, concrete pads, or protective covers.

Amec Foster Wheeler Project No. 7810140065 Page 6 of 11 5/25/2017
3 Groundwater Monitoring Program
Groundwater will be sampled and analyzed on a semi-annual basis. Constituents to be analyzed along
with their respective analytical method and regulatory standards are listed in Table 2. Groundwater
sample results will be compared to the 15A NCAC 2L .0202 (2L Standards) as well as the NCDEQ-SWS
Groundwater Protection Standards (where established). In addition, temperature, pH, specific
conductivity, dissolved oxygen (DO), oxidation reduction potential (ORP), and turbidity will be measured
and recorded for each sample.
3.1 Equipment Calibration
A multi-parameter water quality meter will be used to measure the field parameters listed above in
Section 3. Instrument calibration should be conducted at the start and end of each day, with calibration
reference standards selected to bracket anticipated site groundwater conditions.
3.2 Sampling
Each monitoring well will be fitted with a dedicated stainless steel bladder pump and polyethylene tubing
suitable for low-flow purging and sampling techniques described in Sections 3.2.2 and 3.2.3 below.
Where possible, the pump intake will be placed at least two (2) feet above the bottom of the well to
reduce chances of mobilization of particulates present in bottom of well. The following sections detail
activities associated with low-flow purging and sampling.
3.2.1 Decontamination of Field Sampling Equipment
Each dedicated bladder pump will be properly cleaned and rinsed with distilled water and a phosphate
and borax free detergent prior to installing in the well unless certified as decontaminated from the
supplier. Tubing used for air intake and water discharge connections were new certified-clean supplied
directly from factory packaging.

During subsequent sampling events, the water level probe will be cleaned and rinsed with distilled or
deionized water prior to measuring the water level in each monitoring well.
3.2.2 Well Purging Methods
3.2.2.1 Low-Flow Method
The total well depth was recorded prior to installation of the dedicated pump and will be confirmed when
the pump is removed for inspection or repair. Prior to purging, the initial static water level and total well
depth for each well will be recorded. The volume of water held by the well pump and tubing will be
calculated, as well as the total water volume in the well. Pumping rates and flow rates will be adjusted
such that drawdown is no more than 0.3 feet, if possible. Pumping rates should range between 100
milliliters per min (mL/min) and 500 mL/min. Once an acceptable pumping rate and flow rate is
determined for each well, the indicator parameters listed below will be measured with a multi-parameter
water quality meter and flow-through cell, with the exception of turbidity, which will be measured with a
separate meter. The parameters (along with discharge rate and depth to water) will be recorded over
time, with the frequency of the measurements based on the time required to completely evacuate one (1)
volume of the flow-through cell (typically five (5) minute increments) until stabilization within a certain
range is reached over three (3) consecutive readings. The critical indicator parameters will be pH,
specific conductivity, dissolved oxygen, and turbidity. Each indicator parameter and their respective
stabilization criteria is listed as follows:
• pH ± 0.1 standard units;
• specific conductivity ± 5 percent in microsemens per centimeter (µS/cm);
• dissolved oxygen (DO) ± 0.2 milligrams per liter (mg/L) or 10% saturation;
• turbidity less than 10 NTUs;
• temperature (recorded but not considered a purge stabilization parameter); and
Water Quality Monitoring Plan Duke Energy – Dan River Steam Station
Dan River Landfill Eden, North Carolina

Amec Foster Wheeler Project No. 7810140065 Page 7 of 11 5/25/2017
• oxidation reduction potential (ORP) (recorded but not considered a purge stabilization
parameter).
As listed above, the optimal samples will be obtained at a turbidity of 10 NTU or less. If turbidity levels
are slightly above 10 NTU, but trending downward, purging shall continue. If turbidity readings are
greater than 10 NTU and have stabilized to within 10% during three (3) consecutive readings, attempts
should be made to contact the project manager prior to collecting the groundwater sample. If turbidity
readings are greater than 10 NTU and are not stable, the project manager should be contacted and well
sampling shall be based upon stabilization of more critical indicator parameter (such as DO) without
attainment of the targeted turbidity.
If after five (5) well volumes or two (2) hours of purging (whichever is achieved first), critical indicator
parameters have not stabilized, purging will be discontinued and samples collected. Efforts used towards
stabilization of the parameters (such as modified pumping rates) will be documented.
3.2.2.2 Volume-Averaging Method
There may be instances in which a well has very slow recharge rates, draw down excessively at the
minimum pumping rate of 100 mL/min, or require a higher pumping rate (greater than 500 mL/min) to
maintain purging. In such cases, typical low-flow purging and sampling methods are not appropriate, and
the volume-averaging method will be used. For the volume-averaging method, well volumes (i.e. water
column volumes) will be calculated and three (3) to five (5) well volumes removed. Although indicator
parameter stabilization is not required for the volume-averaging method, the parameters (as well as
discharge rate and depth to water) will still be measured and recorded as follows:
• Initially at the start of purging;
• After each well volume is purged; and
• Just before purge completion.
The removal of three (3) to five (5) well volumes may not be practical in wells with slow recovery rates. If
a well is purged near dryness at a rate of less than 0.5 gallons per minute (gpm), the well shall be allowed
to completely recover prior to sampling. A two (2) hour limit may be exceeded to allow for sufficient
recovery, but samples should be collected within 24 hours of purge completion.
3.2.3 Sample Collection
Following indicator parameter stabilization at each monitoring well location, pump tubing will be
disconnected form the flow-through cell and groundwater will be directly transferred to laboratory provided
pre-preserved sample containers. The sample bottles will be held such that the sample liquid is allowed to
run gently down the side of the bottle to reduce turbulence. The container for metals will be filled first,
followed by the containers for general chemistry parameters.
3.2.4 Sample Labels
Sample labels shall be placed on each sample bottle and remain legible even if wet. The sample labels
should contain at a minimum, the following information:

• Site name;
• Sample ID;
• Well ID;
• Sample date and time;
• Name of sampling personnel;
• Constituents to be analyzed; and
• Preservative (if applicable).

Dan River Landfill Eden, North Carolina

Amec Foster Wheeler Project No. 7810140065 Page 8 of 11 5/25/2017
3.2.5 Sample Preservation and Handling
Upon containerizing groundwater samples, the samples will be packed into pre-chilled, ice-filled coolers
and either hand-delivered or shipped overnight by a commercial carrier to a NC certified laboratory for
analysis. Sample preservation methods will be used to retard biological action and hydrolysis, as well as
to reduce sorption effects. These methods will include chemical preservation, cooling/refrigeration at 4º C,
and protection from light.

Precautions will be taken to reduce movement of samples during transport, including packing the bottles
securely in the cooler. A laboratory provided temperature blank will also be included in the cooler.
Sample coolers should be sealed shut with sturdy tape and tamper seals placed across the cooler
opening.
3.2.6 Chain-of-Custody Program
Properly documented sample chain-of-custody is an essential element of data integrity. Correctly
performed custody procedures inhibit the potential for sample tampering to occur. Custody procedures
will trace the handling of each sample during the collection process, through analysis, until final turnover
for both laboratory and field samples obtained. Chain-of-custody forms are typically provided by the
laboratory and should be completed by qualified sampling staff and laboratory employees. A manually-
prepared chain-of-custody record will be initiated at the time of sample kit preparation by the laboratory
and will remain with the sample kit throughout sample collection, transport, and analysis. Information the
chain-of-custody record may document includes:

• Client name, contact, phone number and address;
• Client project name;
• Sampler(s) name and signature;
• Name and signature of person involved in chain of possession;
• Inclusive dates of possession;
• Sample ID, number, matrix, type (grab or composite);
• Date and time of collection;

numbers also documented in the field books.
3.2.7 Field Logbook
Each field crew conducting sampling activities shall maintain a field logbook to document the activities
conducted by the field crew for each day throughout the course of the field sampling event. At a
minimum, the following information shall be recorded in the field logbook:

• Name and location of the site;
• Pre-Job Safety Brief;
• Date(s) of sample event;
• Name(s) and affiliation(s) of the field sampling crew;
• Time of arrival to the site;
• Weather conditions (including changes throughout the day);
• Pertinent field observations;
• Equipment calibration information;
• Static water level measurements;
• Date and time of well purging;
• Purge volume;

Amec Foster Wheeler Project No. 7810140065 Page 9 of 11 5/25/2017
• Time of sample collection;
• Numbers and types of samples collected, sample identification numbers, and preservatives used;
• A description of sampling methodology and quality control samples (field blanks, duplicates, etc.);
• Water quality indicator parameter readings with time stamp;
• Sample Chain of Custody reference number and cross reference to the sample form data;
• Physical description and picture or sketch of the sample collection location(s) if unusual;
• Record of daily phone calls and/or contact with individuals at the site;
• Documentation of equipment decontamination activities; and
• Description of deviations from the Work Plan.

Field documentation is a crucial element of field activities and, therefore, field crew members should
strictly adhere to logbook entry protocol. Key procedures of field documentation are provided below:

• Logbook should be bound and weather-resistant;
• Consecutively number each page of the logbook;
• Make entries into the logbook in chronological order so that a time notation introduces each entry;
• Use only indelible ink for logbook entries;
• Record data directly and legibly in the field logbook;
• Line out errors in the logbook (a single line strike-through) and initial and date the correction;
• Avoid leaving blank line(s) between logbook entries. Cross out blank spaces that exist with a
single line and initial and date the cross out; and
• Sign and date each page of the logbook (field team member responsible for keeping the
logbook).
3.3 Analytical Procedures
A North Carolina certified laboratory will analyze the groundwater samples for the constituents listed in
Table 2. Analysis will be performed in accordance with Environmental Protection Agency (EPA) Test
Methods for Evaluating Solid Waste, Physical/Chemical Methods (SW 846), which are also listed in Table
2. Alternate SW 846 methods may be used if they have the same or lower reporting limit. The laboratory
must report a detection of any requested constituent even if it is below the Solid Waste Section Limit
(SWSL); however, such concentration will be reported with a qualifier (“J” flag). The laboratory must
include an electronic data deliverable (EDD) spreadsheet with the full laboratory analytical report.
3.4 Quality Assurance and Quality Control Program
Quality Assurance/Quality Control samples will be collected during field activities. Temperature blanks
will be provided by the laboratory in the sample coolers. Temperature blanks will be used to check the
temperature of the samples upon receipt of the cooler to the laboratory. At least one (1) field duplicate
sample will be prepared. A field duplicate is a duplicate sample prepared at an identical sample location,
collected at the same time, in the same container type, containing equal portions of sample medium,
preserved in the same way, and analyzed by the same laboratory as a measure of control. A field blank
may also be collected and analyzed during each monitoring event. A field blank is a sample prepared in
the field and exposed to the sampling environment. A field blank may be prepared by filling appropriate
laboratory bottles with deionized water.

Field QA/QC samples (except for the temperature blank) will be analyzed for the same constituents as
shown in Table 2. Concentrations of any constituents found in the blanks will be used to qualify the
analytical data. Any compound detected in a sample, which was also detected in any associated blank,
will be qualified with a “B” flag.

4 Surface Water Monitoring
Water samples will be collected from four (4) surface water locations on a semi-annual basis as shown on
Drawing 1. Surface water samples will be collected by directly filling laboratory containers with stream
discharge water. Surface water samples will be subjected to the same sample handling, preservation,
chain of custody, labeling, and field logging techniques as groundwater samples described in above
sections. Surface water samples will be analyzed for the same constituents as groundwater samples
(Table 2), and will be compared to respective Classifications and Water Quality Standards Applicable to
Surface Waters and Wetlands of North Carolina as defined in 15A NCAC 2B .0200 (2B Standards).
5 Leachate Monitoring
Leachate will be monitored at the landfill facility on a semi-annual basis. A composite, untreated leachate
sample will be collected from a leachate collection port located at the secondary containment tank pump
pad. The leachate sample will be analyzed for the constituents listed in Table 2, and field indicator
parameters of pH, temperature, and specific conductivity recorded. The leachate sample analysis will be
included in semi-annual reporting, but will not be compared to any water quality standards.
6 Data Evaluation and Reporting
The following sections describe anticipated deliverables in regards to this WQMP.
6.1 Well Abandonment Record Submittal
Well abandonment records are included in Appendix I. A copy of the NCDEQ GW-30 Well
Abandonment Record form (version dated August 2013) has been included in Appendix II.
6.2 Well Construction Record Submittal
Boring logs and well construction records are included in Appendix I. A copy of the NCDEQ GW-1b Well
Construction Record form (version dated August 2013) has been included in Appendix II.
6.3 Monitoring Well Installation Report
