1.0 INTRODUCTION
On behalf of Robeson County, Joyce Engineering (JOYCE) has prepared this Water Quality
Monitoring Plan (WQMP) for the Robeson County Landfill (facility) in accordance with the North Carolina Solid Waste Management Rules (NCSWMR) codified in 15A NCAC 13B.1632-.1637. The facility is currently in assessment monitoring (§.1634) and corrective action (§.1637). This revision of the Water Quality Monitoring Plan was prepared for the proposed
Phase 5 MSW and 1 C&D landfill expansion Permit to Construct Application.
1.1 Site Background
The Robeson County Landfill is located at 246 Landfill Road, just off of Route 20, in St. Pauls,
North Carolina (Figure 1). The facility is owned and operated by Robeson County under Permit
Number 78-03, issued by the North Carolina Department of Environmental Quality (NCDEQ) Solid Waste Section (SWS). The facility occupies 462 acres with the permitted landfill boundaries consisting of approximately 90 acres.
The permitted area is comprised of three active municipal solid waste (MSW) landfill phases
(Phase 2, 3 and 4) and one closed phase (Phase 1). See Drawing WQMP-01, the Site Map, for site layout and features. Phase 1 was opened in 1985 and was closed in accordance with applicable regulations in 1997. Phases 2 through 4 are lined Subtitle-D landfills. Currently, Robeson County has a permit to operate Phases 2 through 4 and a construction and demolition
(C&D) debris landfill on top of the closed Phase 1 landfill. Currently, all MSW is being disposed
in Phase 4 and C&D waste is being disposed in Phase 1. A future C&D waste cell is planned for the area west of Phase 1, and Phase 5 for MSW is proposed for a Permit-to-Construct.
1.2 Site Geology and Hydrology
1.2.1 Site Geology
The Robeson County Landfill is located in the Coastal Plane geologic province. According to the geologic map of the area, the landfill is underlain by the late-Cretaceous (Campanian) Bladen Formation of the Black Creek Group, which is comprised of black clay and light colored micaceous sand deposited in a delta-shelf environment. The Bladen Formation dips gently
toward the east and is underlain by the Tar Heel Formation which is comprised of cross bedded
sands and variegated clays with some gravel. Previous reports indicated that on-site borings encountered surficial geology made up of sand and clay, consistent with the description of the Bladen Formation. A mixture of sand and clay is
present in the shallower portions of borings. Distinct clay layers were identified at
approximately 25 feet and 40 feet below grade.

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 2 Revised March 2017

1.2.2 Site Hydrogeology
The primary aquifer at the site is an unconfined, relatively homogeneous, sedimentary aquifer present from the water table, approximately 4 to 24 feet below ground surface (ft-bgs), to the first confining clay layer at a depth of approximately 25 to 40 ft-bgs. The aquifer is comprised of silt and fine sand and clayey silts and clayey fine sands. Secondary, partially or largely confined aquifers are present below the clay layers. The confining clay layers may not be
contiguous across the entire site. Depth to water ranges from approximately 4 feet at the downgradient, south end of the property to approximately 24 feet at the upgradient, north end of the property. Groundwater flows to the south and southeast, toward Big Marshy Creek.

1.3 Groundwater Flow Regime
Groundwater flow beneath the facility is consistently southward toward Big Marsh Swamp. Linear groundwater flow velocities were computed along selected flow paths perpendicular to groundwater potentiometric surface contours based on water levels measured in April 2015 using
the following modified Darcy equation: V = Ki/n , where V = average linear velocity, K = hydraulic conductivity, i = horizontal hydraulic gradient, and n = effective porosity. The average hydraulic conductivity of the uppermost aquifer at the site is 4.36 feet/day based on slug tests conducted in April 2015 (Joyce, 2015). The effective porosity value is estimated at 85% of
the laboratory-determined porosity for soil samples collected in March-April 2015 (Joyce, 2015).
The average groundwater gradient observed during the April 2015 event was approximately 0.0043. The average estimated linear groundwater flow velocity under the facility was calculated at 22 feet/year (Table 1). The linear velocity equation makes the simplifying assumptions of a homogeneous and isotropic aquifer.

1.4 History and Regulatory Status
1.4.1 Monitoring & Corrective Action History
Robeson County has been performing groundwater monitoring since 1993. Several monitoring wells have had volatile organic compounds (VOCs) present in concentrations that exceed 2L
groundwater standards (15A NCAC 2L.0202) Specifically, contaminants of concern (COCs) at
the site include the organic compounds benzene, 1,1-dichloroethane (1,1-DCA) 1,2-dichloroethane (1,2-DCA) and vinyl chloride and the metals arsenic, chromium, lead and selenium. Following is a summary of the corrective action history of the facility.
● In 2000, a Corrective Action Plan (CAP) was prepared that called for the installation of a
landfill gas recovery trench, with the belief that the VOCs in groundwater were the result
of migrating landfill gas. The trench, which included a number of passive gas vents, was installed in 2000. The trench, approximately 900 feet long, with 10 vents, ran across the eastern portion of the northern side of the Phase 1 landfill.
● In December 2004, in an Assessment of Corrective Measures (ACM) Report, G.N.
Richardson & Associates concluded that the trench did not effectively reduce the

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 3 Revised March 2017

concentrations of VOCs in groundwater collected from monitoring wells MW-9A,
MW-13R, MW-14 and MW-15. The December 2004 ACM report proposed other possible remedies.
● In January 2008, Richardson, Smith, Gardner & Associates (RSGA) prepared a second ACM report. That ACM reported that the trench length was increased and that additional individual vent flares were added. The 2008 ACM also indicated that although there
were decreases in concentrations, some VOCs were still above NC 2L standards. Because of the ongoing exceedances, RSGA included in their ACM report an assessment of potential alternatives for additional remediation efforts at the site. Their assessment looked at monitored natural attenuation, enhanced bioremediation, and groundwater recovery and treatment.
● In June 2008, RSGA submitted a Preliminary CAP that called for supplemental landfill gas recovery [in conjunction with a landfill gas to energy (LFGTE) project that had already been initiated] and enhanced bioremediation. The proposed CAP was approved by NCDEQ on February 11, 2011.
● In 2008 a network of gas extraction wells was installed. The gas collection system was
ultimately hooked up to power generators at the site. The original gas collection trench had been hooked up to the collection system, but because the gas from the trench was not of adequate quality due to its methane content being too low for the generator engine, the trench was disconnected from the collection system. Because gas migration was
controlled by the gas collection system, the collection trench is being decommissioned to
allow for drainage improvements at the site.
● In January 2009, David Garrett & Associates submitted a Sampling and Analysis Plan
Update with Sampling Location Amendments.
● In July 2011, Robeson County conducted an enhanced bioremediation pilot test to assess
the effectiveness of adding a hydrogen (electron donor) supplement to the aquifer to more
rapidly degrade the chlorinated VOCs in groundwater. Prior to the test, three injection points and two additional monitoring points were installed at the site, south of and downgradient from Phase 1, in the vicinity of monitoring well MW-5. In the period since the completion of the pilot test, semi-annual groundwater monitoring has continued.
● In September 2012, Brown & Caldwell issued a letter report on the pilot test and the
subsequent monitoring results that concluded that the addition of the supplement did not effectively improve degradation.
● In January 2013, the NCDEQ approved cessation of sampling for herbicides and pesticides for the facility wells under assessment monitoring.
● In August 2013, Joyce Engineering (JOYCE) submitted a Corrective Action Evaluation
Report (CAER) for the facility. The CAER concluded that enhanced bioremediation would not be effective for this facility and recommended that the facility pursue control of landfill gas plus monitored natural attenuation (MNA) as the remedy.

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 4 Revised March 2017

● In July 2014, JOYCE submitted and NCDEQ approved a request to change MW-13R,
MW-14, & MW-15A to Assessment Monitoring and to let MW-3R, MW-10, & MW-11 revert back to Detection Monitoring.
1.4.2 Regulatory Status
The Robeson County Landfill operates under permit 78-03. Phase 1 is a closed unlined MSW
landfill, which opened in 1985 and operated until 1997. It is covered with a 24-inch soil cap. The County has operated a C&D landfill on top of the closed MSW landfill since 1998. Phases 2, 3, and 4 are lined Subtitle-D landfills, permitted and constructed in accordance with the NCSWMR.
Both detection and assessment monitoring are being performed at the site. The wells associated with Phase 1 are in assessment monitoring under §.1634 of the NCSWMR. Phase 1 is also under corrective action under §.1637 of the NCSWMR because of the presence of VOCs and metals in exceedance of groundwater protection standards (GPS) as defined in §.1634.g of the NCSWMR. The wells associated Phases 2, 3, and 4 are in detection monitoring under §.1633 of
the NCSWMR.

* In July 2014, NCDEQ approved a request to change MW-13R, MW-14, & MW-15A to Assessment Monitoring and to let MW-3R, MW-10, & MW-11 revert back to Detection Monitoring. This table reflects those changes. ** In January 2013, NCDEQ approved removing the requirement of sampling for herbicides and pesticides. *** MW-24 will be abandoned once construction of Phase 5 is approved. **** MW-19 and MW-20 will be abandoned prior to construction of the C&D expansion and will be replaced by proposed wells MW-19R and MW-20R.
There are currently 20 monitoring wells that are part of the active compliance monitoring
network for the facility. Monitoring wells MW-6 and MW-12 serve as upgradient background wells for the facility. Six down-gradient wells associated with Phase 1, including MW-3R, MW-5, MW-8, MW-9A, MW-10 and MW-11. Eleven wells are associated with Phases 2, 3, 4, and 5 including MW-13R, MW-14R, MW-15A, MW-16, MW-17R, MW-18, MW-21, MW-22,
MW-23, MW-24, MW-25R and MW-26. MW-24 must be abandoned prior to construction of
Phase 5; therefore, it will be removed from the monitoring network at that time. A future C&D cell is planned for the area immediately west of Phase 1. Monitoring wells MW-19 and MW-20 are downgradient of the future C&D cell; however, they will need to be
abandoned prior to construction. Replacement wells MW-19R and MW-20R are proposed further downgradient of the future C&D cell, but within the relevant point of compliance (< 250 feet from the edge of waste). MW-21 is located upgradient of the future C&D Cell, but downgradient of Phase 3, and it is currently sampled for Phase 3 compliance.
The locations of the facility monitoring wells are shown on Drawing WQMP-01, and proposed new wells are shown in red. Construction specifications for these monitoring wells are summarized in Table 2 and available well boring and construction logs are included in Appendix A.
2.2 Surface Water Monitoring Program
The two surface water sampling locations are monitored at the facility. Sampling point SW-1 is located at the outfall of the sedimentation basin on the south side of Phase 1. Surface water sampling point SW-2 is across the access road in the southeast corner of Phase 2. Samples are collected from SW-1 and SW-2 during each semiannual sampling event if there is sufficient
water flow. These locations are shown in red on Drawing WQMP-01. Due to the distance to Big Marsh Creek, NCDEQ has not required Robeson County to sample water from the creek. The surface water samples are analyzed for the NCSWMR Appendix I list of constituents during both semiannual events.
3.0 SAMPLING PROTOCOLS
3.1 Groundwater Sampling Methodology
Groundwater samples will be collected in accordance with NCSWMR §.1630 through §.1633 and guidance provided in the Draft North Carolina Water Quality Monitoring Guidance
Document for Solid Waste Facilities; Solid Waste Section, Division of Solid Waste Management;
Department of Environment, Health and Natural Resources (March 1995). Details of well

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 6 Revised March 2017

purging, sample withdrawal, and decontamination methods, as well as chain-of-custody
procedures are outlined below. Static water elevations and the total well depth will be measured to the nearest 0.01 of a foot in each well prior to the sampling of each well. An electronic water level meter will be used for the measurements. The distance from the top of the well casing to the water surface and to the
bottom of the well will be measured using the tape attached to the probe. Reference elevations of the proposed wells have been obtained from a North Carolina registered land surveyor. A low-yield well (one that is incapable of yielding three well volumes within a reasonable time) will be purged so that water is removed from the bottom of the screened interval. Low-yield
wells will be evacuated to dryness once. Within 24 hours of purging, the first sample will be field tested for pH, temperature, and specific conductance. Samples will then be collected and containerized in the order of the parameters' volatilization sensitivity (i.e., volatile organics then total metals).
A high-yield well (one that is capable of yielding more than three well volumes during purging) will be purged so that water is drawn down from the uppermost part of the water column to ensure that fresh water from the formation will move upward in the screen. At no time will a well be evacuated to dryness if the recharge rate causes the formation water to vigorously
cascade down the sides of the screen, which could cause an accelerated loss of volatiles.
A minimum of three well volumes will be evacuated from high-yield wells prior to sampling. A well volume is defined as the water contained within the well casing and pore spaces of the surrounding filter pack. The well volume will be calculated using the following formulas:

Vc = (dc2/4) x3.14 x hw x (7.48 gallons/cubic foot) Vc (gallons) = 0.163 x hw (for a 2-inch well) where: Vc = volume in the well casing in gallons
dc = casing diameter in feet (dc = 0.167 for a 2-inch well)
hw = height of the water column in feet (i.e., well depth minus depth to water) Each well will be evacuated (purged) and sampled with a disposable bailer or a sampling pump. The bailer or pump will be lowered gently into the well to minimize the possibility of causing
degassing of the water. If sampled with a pump, flow rates will be regulated to minimize
turbidity and degassing of the water. All equipment used for sampling will be handled in such a manner to ensure that the equipment remains decontaminated prior to use. In between wells and following completion of the field
sampling, water level meters, sampling pumps, or any other reusable sampling equipment will be
properly decontaminated. Clean disposable gloves will be worn by sampling personnel and changed between wells.

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 7 Revised March 2017

The upgradient/background well will be sampled first, followed by the downgradient wells. The
order of sampling of the downgradient wells will be evaluated each sampling event to provide a sequence going from less contaminated to more contaminated, if applicable, based on the previous sampling event. Field measurements of temperature, pH, specific conductance, and turbidity will be made before sample collection. The direct reading equipment used at each well will be calibrated according to the manufacturer's specifications prior to each sampling event.
Groundwater samples will be collected and containerized in the order of the volatilization sensitivity as follows (as required):
 Volatile and purgeable organics;
 Base neutral and acid extractable organics;
 Total metals;
 Dissolved metals; and
 BOD, COD, dissolved methane, nitrate, sulfate. Pre-preserved sample containers will be supplied by the laboratory. The VOC vials will be filled in such a manner that no headspace or entrapped air bubbles remain after filling. Immediately
upon collection, all samples will be placed in coolers on ice where they will be stored prior to and during transit to the laboratory. In between wells and following completion of the field sampling, the electronic depth meter will
be decontaminated using the following procedure:
1) Phosphate-free soap and distilled water wash; 2) Distilled water rinse; and 3) Air dry.
Samples collected will be properly containerized, packed into pre-cooled coolers, and either
hand-delivered or shipped via overnight courier to the laboratory for analysis. The chain-of-custody program will allow for tracing of possession and handling of samples from the time of field collection through laboratory analysis. The chain-of-custody program will include sample labels and seals, field logs, chain-of-custody records, and laboratory logs. Example field logs
and an example chain-of-custody form are included in Appendix B.
Labels sufficiently durable to remain legible when wet will contain the following information:
 Job and sample identification;
 Monitoring well number or other location;
 Date and time of collection;
 Name of collector;
 Parameter to be analyzed; and
 Preservative, if applicable. The shipping container will be sealed to ensure that the samples have not been disturbed during
transport to the laboratory. If the sample cannot be analyzed because of damage or disturbance, whenever possible, the damaged sample will be replaced during the same compliance period. The field log will contain sheets documenting the following information:
 Identification of the well;

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 8 Revised March 2017

 Well depth;
 Static water level depth;
 Presence of immiscible layers, odors or other indications of potential contamination;
 Purge volume (given in gallons or number of bailers);
 Time well was purged;
 Date and time of collection;
 Well sampling sequence;
 Field analysis data and methods;
 Field observations on sampling event;
 Name of collector(s);
 Climatic conditions (temperature, precipitation).
The chain-of-custody record is required to establish the documentation necessary to trace sample
possession from time of collection to time of receipt at destination. A chain-of-custody record will accompany each individual shipment. The record will contain the following information:
 Sample destination and transporter;
 Sample identification numbers;
 Signature of collector;
 Date and time of collection;
 Sample type;
 Identification of well;
 Number of sample containers in shipping container;
 Parameters requested for analysis;
 Signature of person(s) involved in the chain of possession;
 Inclusive dates of possession; and
 Internal temperature of shipping container upon opening (noted by the laboratory). A copy of the completed chain-of-custody sheet will accompany the shipment and will be returned to the shipper with the analytical results. The chain of custody record will also be used
as the analysis request sheet.
A field blank and/or an equipment blank will be collected and analyzed during each sampling event to verify that the sample collection and handling processes have not affected the integrity of the field samples. The field/equipment blank(s) will be prepared in the field from distilled
water (type II reagent grade water) supplied by the laboratory. At least one field/equipment blank will be prepared for each sampling event. Equipment blank will be generated by exposing the laboratory-distilled water to the sampling environment and sampling equipment/media in the same manner as actual field samples being collected. A field blank will be generated by exposing the laboratory-distilled water to the sampling environment at each sampling location
during the sampling event. The laboratory will provide appropriate sample containers for generation of the field/equipment blank(s). The field/equipment blank(s) will be subjected to the same analyses as the groundwater samples. As with all other samples, the time(s) of the field/equipment blank collection will be recorded so that the sampling sequence is documented. The field/equipment blank monitors for contamination from the sampling equipment/media, or
from cross-contamination that might occur between samples and sample containers as they are opened and exposed to the sampling environment.

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 9 Revised March 2017

Whenever groundwater samples are being collected for volatiles analysis, a trip blank will be
generated by the laboratory using laboratory-distilled water prior to shipment of sampling containers and coolers to the field. The trip blank shall be transported with the empty sampling containers to the field, but will not be opened at any time prior to analysis at the laboratory. The trip blank will accompany the groundwater samples in the cooler(s) back to the laboratory and will be analyzed by the same volatile methods as the associated field samples. The trip blank
monitors for potential cross-contamination that might occur between samples or that may be a result of the shipping environment. Detectable levels of contaminants found in the field/equipment blanks or trip blanks will not be used to correct the groundwater data, but will be noted accordingly. Constituents detected in
trip blanks or field/equipment blanks at concentrations within an order of magnitude of those observed in the corresponding groundwater or surface water samples may justify discounting the detections in samples as ‘blank-qualified”, or may be cause for resampling.
3.2 Surface Water Sampling Methodology
Surface water samples will be collected from flowing water at the designated sample locations in conjunction with the semiannual groundwater sampling events. Surface water can be sampled either by: 1) collecting the sample using a properly-decontaminated dipper and filling laboratory-prepared sample containers from the dipper; or 2) by dipping laboratory-prepared
sampled containers directly into the stream flow. If using the direct sampling method, great care
should be taken to not overflow containers containing preservatives to prevent loss of preservative. Use of an unpreserved laboratory container to collect the sample and then carefully dispense it into the preserved container is acceptable. For unpreserved containers, it is preferable to completely submerge the closed container, remove the lid underwater, and then replace the lid
when the container is full before removing it from the water; however, this method is only
acceptable if there is sufficient depth of flowing water. No matter what method is used to collect samples, great care should be taken to not disturb creek bed sediment during sampling and to obtain samples from the least turbid location available. Downstream samples should be collected first and upstream samples second. Samplers should wear clean, dedicated sampling gloves at all
times while collecting or handling samples. Field parameters, including temperature, pH, and
turbidity, shall be monitored at each sample location using the same sample collection technique used to collect the laboratory samples, as appropriate. Sampling techniques and protocols describe above for groundwater, including sample labeling, field log entry, and chain-of-custody procedures, shall also be followed for surface water samples.

3.3 Sample Analytical Requirements
3.3.1 Analytical Requirements
The groundwater from wells in detection monitoring and surface water samples will be analyzed for the NCSWMR Appendix I list of constituents (by reference, RCRA Subtitle-D, Appendix I of
40 CFR.258). Groundwater from monitoring wells in assessment monitoring shall be analyzed
for the NCSWMR Appendix II list of constituents (by reference, RCRA Subtitle-D, Appendix II of 40 CFR.258) during the first semiannual sampling event of each year. During the second

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 10 Revised March 2017

semiannual sampling event, these wells shall be sampled for the Appendix I list of constituents
plus previously detected Appendix II constituents. Note that in a letter dated January 24, 2013, the NCDEQ approved cessation of sampling for herbicides and pesticides for the facility wells under assessment monitoring, so the Appendix II list for this facility no longer includes herbicides or pesticides.
In addition to the above requirements, samples from compliance wells that monitor a C&D waste unit (currently Phase 1) shall be analyzed for C&D parameters: mercury, chloride, manganese, sulfate, iron, alkalinity, and total dissolved solids (TDS) in accordance with §.0544(b)(1)(D). All groundwater and surface water samples shall also be analyzed for the following field parameters: pH, specific conductivity, temperature, and turbidity.
Analysis of groundwater and surface water samples shall be performed in accordance with U.S. EPA SW-846 methods as described in Test Methods for Evaluating Solid Waste -
Physical/Chemical Methods (SW-846) or Methods for the Chemical Analysis of Water and
Wastes. All laboratory analyses will be performed by laboratories certified by the NCDEQ for
the required analytical methods and parameters. Appendix C includes a table of all Appendix I and Appendix II constituents with their respective analytical methods, CAS numbers, NCDEQ Solid Waste Section Limits (SWSL), 15A NCAC 2L (NC2L) groundwater standards, and Solid Waste Section groundwater protection standards (GWPS). Appendix D includes a summary of
15A NCAC 2B (NC2B) Surface Water Standards. Analyses shall be consistent with NCDEQ
policies regarding analytical methods, SWSLs, and practical quantitation limits (PQLs), as appropriate.
3.3.2 Reporting and Record Keeping
The laboratory analytical results shall be submitted to the Solid Waste Section semiannually.
The following measurements, analytical data, calculations, and other relevant groundwater monitoring records will be kept throughout the active life of the facility and the post-closure care period:
 Records of all groundwater quality data;  Associated sample collection field logs and measurements, such as static water level
measured in compliance wells at the time of sample collection; and

 Notices and reports of GPS exceedances, reporting or data error, missing data, etc.

3.4 Well Abandonment
Any monitoring wells at the site which need to be abandoned due to damage, construction activities, or approved changes in the monitoring network will be properly abandoned in accordance with the procedures for permanent abandonment, as described in 15A NCAC 2C § .0113(d). Prior to abandonment, approval must be received from the SWS and will also be certified by a licensed geologist. No wells will be abandoned without prior approval from the
SWS.

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 11 Revised March 2017

3.5 Comparison to GPS
Constituents detected in the samples collected from the compliance well network shall be compared to the appropriate GPS for that constituent in accordance with NCSWMR §.1634.g-h.
The comparison will be performed using a value-to-value procedure. If a suspect GPS
exceedance is noted during the value-to-value comparison, a confirmation sample may be collected. The results from a confirmation sample will be compared to the GPS in a value-to-value comparison, or the value may be statistically compared to background.
In most cases, the GPS will be equal to the Groundwater Standard established for a given
constituent in 15A NCAC 2L.0202 (NC2L Standards). For constituents without listed NC2L Standards, the groundwater protection standards (GWPS) established by the NCDEQ Solid Waste Section may be used. In the event that a site-specific statistical background value can be established for a given constituent which is higher that the NC2L standard, GWPS, or other
appropriate listed standard, the background may be used as the GPS with NCDEQ approval per
NCSWMR §.1634.g.5.
3.6 Statistical Analyses
With the April 2011 revision to the NCSWMR, routine statistical comparison to background for
all detected constituents is no longer required for landfills regulated under §.1600 of the
NCSWMR; however, statistical analyses may be used to establish an alternate GPS for constituents with the approval of the NCDEQ if desired by the facility. For C&D landfills regulated under §.0500 of the NCSWMR, statistical comparison to background is required for all detected constituents. The following guidelines will be used to determine statistical background
values.
Statistical analyses shall be conducted in compliance with the EPA guidance document,
Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities, Unified Guidance (US-EPA, 2009). The background data are to be evaluated through the use of Parametric Prediction
Limits, Parametric Tolerance Intervals, Non-Parametric Prediction Limits, or Poisson Prediction
Limits as appropriate. Tests for normality, outliers, Aitchison’s adjustment, tolerance intervals, or prediction limits are to be included as appropriate based on the background data. The statistical test by which downgradient data are compared to facility background data is based upon the nature of the data and the number of data values that are less than the laboratory limit of
detection. All statistical tests are evaluated at the 0.05 level of significance, 95% confidence
level, and are conducted as one-tailed tests. These methods and the criteria for their use are discussed below.
3.6.1 Treatment of Censored Data
Generally, background data are censored as follows. When less than or equal to 15% of the
background data values are less than the applicable reporting limit or quantitation limit (generally, the SWSL), any data reported at less than the applicable limit will be treated as one-half the limit.

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 12 Revised March 2017

3.6.2 Assumption of Normality
Prior to conducting statistical tests that are based on the assumption of normally distributed data, normality of the background data shall be evaluated using the Shapiro-Wilk statistic (W). Normality shall be assessed at the 95% confidence level. In the event that the raw data fail to follow a normal distribution, the data shall be transformed using a base-10 logarithm. The
transformed data shall then be tested for normality using the Shapiro-Wilk statistic. In the event that the log-transformed data also fail to follow a normal distribution, a non-parametric approach shall be applied.
3.6.3 Parametric Upper Tolerance Limit
When the background data consist of a minimum of eight independent data values and less than or equal to 15% of the background data values are less than the DL for a given analyte, the downgradient values are then compared to the parametric upper tolerance limit in accordance with the procedure summarized in the EPA guidance document (US-EPA, 2009).
3.6.4 Aitchison’s Adjusted Parametric Upper Prediction Limit
In those cases where the background data consist of a minimum of eight independent data values and more than 15%, but less than or equal to 50%, of the background data values are truncated (below than the DL) for a given analyte, the mean and standard deviation are adjusted. This is
done in accordance with the procedure described by Aitchison and summarized in the EPA
guidance document (US-EPA, 2009). After the adjustments are made, the downgradient values are compared to the Aitchison’s adjusted parametric upper prediction limit in accordance with the procedures summarized in the EPA guidance document (US-EPA, 2009).
3.6.5 Non-parametric Upper Tolerance Limit
In those cases where more than 50%, but less than or equal to 90%, of the background data values are truncated (below than the DL) for a given analyte or the background data fail to follow a normal or log-normal distribution, downgradient values are compared to the non-parametric upper tolerance limit. This procedure is done in accordance with the procedures
summarized in the EPA guidance document (US-EPA, 2009).

3.6.6 Poisson Upper Prediction Limit
In those cases where more than 90% of the background data values are truncated (below than the DL) for a given analyte, the downgradient values are compared to the Poisson upper prediction
limit. These comparisons are made in accordance with the procedure summarized in the EPA
guidance document (US-EPA, 2009).

Water Quality Monitoring Plan Joyce Engineering Robeson Co. Landfill, Permit No. 78-03 13 Revised March 2017

3.7 Surface Water Monitoring
Surface water at the facility is currently monitored semiannually in conjunction with the groundwater sampling events. Samples are collected from two surface water monitoring points, SW-1 and SW-2, when there is sufficient flow. Surface water samples will be collected and analyzed for the NCSWMR Appendix I list of constituents during both semiannual monitoring events. The results will be compared to 15A NCAC 2B (NC2B) Surface Water Standards in a
value-to-value comparison. See Section 3.2 for surface water sampling methodology.
3.8 Leachate Monitoring
Leachate samples for Phases 2, 3, 4 and 5 shall be collected from the site on a semiannual basis. These samples are collected from the piping in the leachate treatment building prior to the
treatment process. Phase 2, 3 and 5 leachate samples are collected from the respective line valves linked to the generator. The Phase 4 leachate samples are collected from the line pump station G1-D located on the east end of Phase 4. The locations for collecting leachate samples are shown on Drawing WQMP-01.
Leachate samples shall be collected and analyzed for Appendix I parameters plus BOD, COD, nitrates, phosphates, and sulfates in accordance with NCDEQ requirements. These data shall be reported in the facility’s semiannual Water Quality Monitoring Reports to NCDEQ on a semiannual basis.

4.0 ABILITY TO EFFECTIVELY MONITOR RELEASES
Based on the hydrogeologic data available for the Robeson County Landfill, no geological or hydrological conditions have been identified which are likely to interfere with effective monitoring of groundwater beneath the facility. The existing monitoring network is considered
adequate to monitor this facility. This Water Quality Monitoring Plan will be effective in
providing detection of any release of landfill constituents to the uppermost aquifer beneath the facility as well as monitoring of existing releases, so as to be protective of public health and the environment.
