1.0 INTRODUCTION

On behalf of Upper Piedmont Regional Landfill, Jett Environmental Consulting statistically evaluated the
First Semi-Annual 2024 water quality monitoring data. Sampling was completed by Environmental
Sampling & Services, Inc. on May 7-8, 2024 and analytical testing was performed by Pace Analytical
Services, LLC. The statistical analysis software package utilized, SanitasTM, follows a documented decision
logic that incorporates the following applicable document: USEPA “Statistical Analysis of Groundwater
Monitoring Data at RCRA Facilities, Unified Guidance” (March 2009).
2.0 SITE BACKGROUND AND MONITORING NETWORK

Per the site’s Water Quality Monitoring Plan dated June 2009 by Hodges, Harbin, Newberry, & Tribble, Inc.
and in compliance with North Carolina Department of Environmental Quality (DEQ) Solid Waste
Management Regulations, Section .1600 “Requirements for Municipal Solid Waste Landfill Facilities,” Jett
Environmental Consulting statistically evaluated parameters from the First Semi-Annual 2024 event using
inter-well prediction interval analysis. Prediction intervals are considered a powerful tool for groundwater
statistical analysis, when feasible, due to their inherent low false negative and false positive rates utilizing
confirmatory resampling, if necessary.

Monitoring well GW-1R is the facility’s background well and is located hydraulically upgradient of the waste
disposal area. Well GW-10 was upgradient to waste prior to December 2020. Cell 5B began accepting
waste in December 2020. As a conservative measure, data collected from GW-10 in 2021 and onward will
be considered downgradient for statistical analysis purposes. Monitoring wells GW-2, GW-3, GW-4R,
GW-5, GW-6, GW-7, GW-8, GW-9, GW-11, and GW-12 are located downgradient or side-gradient of the
waste disposal area and represent the facility’s downgradient compliance wells. The monitoring wells are
equipped with dedicated bladder pumps and were purged and sampled via the low-flow method. Table 1
lists the groundwater monitoring wells for the site. Each well was sampled during the First Semi-Annual
2024 event. The parameters subject to statistical evaluation during detection monitoring are noted in DEQ
Section 1633 as constituents listed in Appendix I of 40 CFR Part 258 “Constituents for Detection
Monitoring”.

Monitoring well GW-1R was installed in July 2009 as a replacement background well for GW-1, which had
been dry during several consecutive sampling events. Well GW-1R was sampled for the first time during
the January 2010 sampling event. Well GW-1 was decommissioned following the July 2009 event.

Downgradient wells GW-9 and GW-10 were installed in July 2009 and wells GW-7 and GW-8 were installed
in April 2012 to monitor groundwater downgradient of the new Phase 3 waste unit (Cells 5A and 6A).
Background sampling for these four wells began in May 2012 and was completed in August 2012 including
four rounds of pre-waste samples collected between May and August 2012.

According to the site, during maintenance efforts along the powerline right of way on site, well GW-4 was
damaged beyond repair by a tree clearing service company. Therefore, well GW-4 was abandoned in
October 2018 and a replacement well (GW-4R) was installed in October 2018 as documented in the
Groundwater Monitoring Well Abandonment and Installation Report dated December 17, 2018 by Bunnell-
Lammons Engineering, Inc. Well GW-4R was sampled for the first time in January 2019.

Downgradient wells GW-11 and GW-12 were installed in February and March 2023 to monitor groundwater
downgradient of Cell 6B. Background sampling for these two wells began in May 2023 and was completed
in October 2023, including four rounds of pre-waste samples collected between May and October 2023.

In a May 29, 2018 memorandum, DEQ requested groundwater and surface water samples be analyzed for
1,4-dioxane. Groundwater and surface water samples were collected for 1,4-dioxane during the Second
Semi-Annual 2018 and First Semi-Annual 2019 events in accordance with this request even though this
parameter is not specified in the rules or approved monitoring plan. There were no detections of 1,4-dioxane
in the groundwater and surface water samples for the Second Semi-Annual 2018 and First Semi-Annual
Groundwater Statistical Analysis Report

2019 events. Therefore, consistent with direction provided by DEQ for other North Carolina landfills, the
Upper Piedmont Regional Landfill has ceased sampling groundwater and surface water for 1,4-dioxane.
Per DEQ requests for other North Carolina landfills, the leachate will be analyzed annually for 1,4-dioxane.
The site has a surface water monitoring network consisting of one upstream surface water sampling point
(SW-1) and one downstream point (SW-2). These points are sampled semi-annually for the 40 CFR Part
258 Appendix I list in conjunction with the groundwater monitoring wells. During the First Semi-Annual 2024
event, SW-1 and SW-2 were able to be sampled.

A leachate sample is also collected semi-annually for analysis in accordance with the facility’s permit. The
leachate sample is analyzed semi-annually for the 40 CFR Part 258 Appendix I list, ammonia, biochemical
oxygen demand (BOD), cyanide, nitrate-nitrite, pH, phosphorous, and total suspended solids (TSS). In
addition, the leachate is also analyzed annually (first semi-annual events) for 1,4-dioxane, chemical oxygen
demand (COD), total Kjeldahl nitrogen (TKN), sulfate, total dissolved solids (TDS), gasoline range organics
(GRO), diesel range organics (DRO), and benzene, toluene, ethylbenzene, and xylenes (BTEX).
3.0 SITE HYDROGEOLOGY

The following site hydrogeology summary was taken from the Second Semi-Annual Water Quality
Monitoring Report of 2017, dated September 25, 2017 by Joyce Engineering.

Geologically, the facility is located within the Carolina Slate Belt of the Piedmont Physiographic Province of
North Carolina. The Carolina Slate Belt is composed of Late Proterozoic to Cambrian meta-sedimentary
and meta-volcanic rocks that locally have been intruded by diabase dikes and felsic intrusive suites. The
rocks underlying the facility are mapped as felsic meta-volcanics (dacitic and rhyolitic tuffs and flows
interbedded with mafic meta-volcanics).

The uppermost groundwater beneath the facility is contained in a shallow, unconfined aquifer comprised of
partially weathered, fractured, meta-volcanic rock. Groundwater occurs at depths of approximately 40 feet
below grade along the western, upgradient side of the waste disposal area, and at an average depth of 5
feet below grade along the eastern boundary.

Appendix A provides a potentiometric surface map utilizing groundwater level data from the First Semi-
Annual 2024 event. Groundwater flow direction for the First Semi-Annual 2024 event was to the East,
toward tributaries of Club Creek, which borders the eastern portion of the property. The First Semi-Annual
2024 event groundwater flow direction was consistent with past events. Groundwater flow rate for the First
Semi-Annual 2024 event was estimated at 6.21 feet/year, consistent with past events. Flow rate
calculations are available in Appendix A.
4.0 DATA EVALUATION

Appendix C contains a copy of the laboratory analytical report and field sampling forms for the First Semi-
Annual 2024 groundwater, surface water, and leachate sampling event. The analytical results for the First
Semi-Annual 2024 event for the groundwater, surface water, and leachate samples are summarized on
Tables 2, 3, and 4, respectively.

No volatile organic compounds (VOCs) were detected at quantified concentrations above a laboratory
practical quantitation limit (PQL) in groundwater samples; therefore, VOCs were not included on Table 2.

As shown on Table 2, four NC Appendix I inorganic constituents were detected at quantified concentrations
in samples from one or more wells:

 barium at GW-3, GW-4R, GW-5, GW-7, GW-8, and GW-10;
 cobalt at GW-2, GW-8, and GW-12;
 copper at GW-2; and,
 zinc at GW-8.

4.1 NC 2L Standards
15A NCAC 02L .0202(a) GROUNDWATER QUALITY STANDARDS: These are the maximum allowable
concentrations used by DEQ, which DEQ considers may be tolerated without creating a threat to human
health or which would otherwise render the groundwater unsuitable for its intended best usage.

Per 15A NCAC 02L .0202(b)(1), for the NC 2L Standards, only detections of a substance at or above the
PQL can constitute a violation of the standard. Therefore, estimated values below the PQL are not
considered a violation of a NC 2L Standard.

As stated in the Regulation above, where naturally occurring substances exceed the established NC 2L
Standard, the standard shall be the naturally occurring concentration. The naturally occurring background
concentrations are addressed in Section 8.0 below.

Groundwater quality standards are established by 15A NCAC 02L .0202 as the lowest of the following six
criteria: (1) A concentration protective of the non-cancer or systemic effects of a contaminant; (2) A
concentration which corresponds to an incremental lifetime cancer risk of one-in-a-million as determined
by DEQ; (3) The taste threshold limit value; (4) The odor threshold limit value; (5) The National Drinking
Water Maximum Contaminant Level; or (6) The National Secondary Drinking Water Standard.

Results

One Appendix I constituent was detected at quantified concentrations above an NC 2L Standard during the
First Semi-Annual 2024 sampling event: cobalt. The cobalt concentrations at GW-2 (11.8 ug/L), GW-8 (30.9
ug/L), and GW-12 (12.0 ug/L) were above the NC 2L Standard (1.0 ug/L), consistent with past events.

4.2 Background Statistical Evaluation for 2L Exceedances

Per 15A NCAC 02L .0202(b)(3), where naturally occurring substances exceed the established NC 2L
Standard, the standard shall be the naturally occurring concentration.

As stated in 15A NCAC 13B .1632(g), sites may choose to perform statistical analysis of groundwater
quality data whether for purposes of establishing background concentrations or to determine if there is an
exceedance of the groundwater protection standard (i.e., NC 2L). Section 5.0 summarizes the statistical
evaluation to determine if background (i.e., naturally occurring levels) was exceeded. If a quantified
concentration is detected above a NC 2L Standard but statistically below background, then an exceedance
has not occurred.

Inter-well statistical evaluations were performed on any quantified detections above a NC 2L Standard at
downgradient wells. As stated in 15A NCAC 02L .0202, where naturally occurring substances exceed the
established NC Standards, the standard shall be the naturally occurring concentration. Therefore, further
action is only necessary if concentrations exceed a NC 2L Standard and exceed the background statistical
limit.

For the First Semi-Annual 2024 event, there were no inter-well background prediction limit exceedances
exhibited for the groundwater monitoring program wells (see Section 5.2), with the exception of cobalt at
GW-8.
5.0 STATISTICAL PROCEDURES
Statistical analyses (i.e., inter-well prediction limits) were performed to establish background concentrations
and determine if the NC 2L Standard value-to-value exceedance for cobalt exhibited a statistically
significant increase.

Upper Piedmont Regional Landfill, North Carolina 4

5.1 Outlier Analysis

The background data were evaluated for the presence of statistical outliers. Methodologies for determining
a statistical outlier are defined in the USEPA Unified Guidance. Any statistical outliers that were determined
were removed from the background data set prior to performing prediction interval statistical analysis.
According to the USEPA Unified Guidance, data that are not normally or log-normally distributed are not
recommended for evaluation of outliers. In cases where the data were not normally or log-normally
distributed, outliers were not removed from the data set. Background outliers flagged for removal are
identified on the statistical plots provided in Appendix B.

5.2 Inter-Well Prediction Intervals

The prediction interval is a statistical method used to compare a single observation to a group of
observations. The prediction interval is calculated to include observations from the same population with a
specified confidence. In groundwater monitoring, a prediction interval approach may be used to make
comparisons between background and compliance data. The interval is developed to contain all future
observations, within a certain probability. For the site, inter-well prediction intervals have been developed
based on a 99% confidence that future observations will fall within the range. If any future observation
exceeds the prediction interval, this is considered statistically significant evidence that the observation is
not representative of the background group.

During parametric prediction interval analysis, the mean and the standard deviation are calculated for the
raw or transformed background data. The number of comparison observations, K, is defined to be included
in the interval. If less than 15% of the background observations are nondetects, the nondetects are replaced
with one half of the reporting limit prior to performing the analysis. If more than 15% but less than 50% of
the background data are below the reporting limit, the data’s sample mean and standard deviation are
adjusted according to the Kaplan-Meier method. However, when the background data are not transformed-
normal or contain greater than 50% observations below the reporting limit, SanitasTM automatically
constructs a non-parametric prediction interval. During non-parametric analysis, the highest value from the
background data is used to set the upper limit of the prediction interval.

Due to the wide range of laboratory reporting limits utilized over time, the historical reporting limits were
conservatively replaced with the current event reporting limit prior to performing statistical analyses.

Groundwater monitoring was initiated in May 1997. Background is defined as samples collected from
previously installed upgradient well GW-1, current upgradient well GW-1R from May 1997 through the
current event, and well GW-10 prior to waste placement in December 2020.

In correspondence dated July 2, 2018, the site submitted an Alternate Source Demonstration (ASD)
Addendum to update the statistical limit for cobalt based on background pre-waste data for GW-1R, GW-8,
and GW-10. The updated inter-well statistical limit for cobalt was calculated to be 23 ug/L. DEQ approved
the updated ASD Addendum and updated statistical limit in correspondence dated July 24, 2018. The July
24, 2018 DEQ letter stated the facility should use the same methodology to calculate background statistical
limits in the future. When adding additional cobalt values from low turbidity samples since the last update,
the cobalt background statistical limit for the First Semi-Annual 2024 event was calculated to be 21 ug/L.

Summary tables and graphs for the inter-well prediction interval analysis are available in Appendix B.
Included in Appendix B are time series plots for each of the inorganic constituents.
6.0 NC 2B SURFACE WATER STANDARDS

As shown on Table 3, during the First Semi-Annual 2024 event, no NC 2B Surface Water Standards were
exceeded in surface water samples for quantified detections.

7.0 LEACHATE SAMPLING

The constituents detected in the leachate sample collected during the First Semi-Annual 2024 event were
typical for leachate at this facility. Table 4 provides a summary of the leachate results.
8.0 CONCLUSIONS

No VOCs were detected at quantified concentrations above a PQL in groundwater or surface water samples
during the First Semi-Annual 2024 event.

One Appendix I constituent was detected at quantified concentrations above an NC 2L Standard during the
First Semi-Annual 2024 sampling event: cobalt. The cobalt concentrations at GW-2 (11.8 ug/L), GW-8 (30.9
ug/L), and GW-12 (12.0 ug/L) were above the NC 2L Standard (1.0 ug/L), consistent with past events.

Statistical analyses (i.e., inter-well prediction limits) were performed to establish background concentrations
and determine if the NC 2L Standard value-to-value exceedances for quantified detections also exhibited
a statistically significant increase.

For the First Semi-Annual 2024 event, there were no inter-well background prediction limit exceedances
exhibited for the groundwater monitoring program wells, with the exception of cobalt at MW-8. The cobalt
concentration at GW-8 (30.8 ug/L) was above the inter-well background statistical limit for cobalt (21 ug/L).
The cobalt concentration at GW-8 was consistent with the historical range of cobalt at this well (10.7 to 97.1
ug/L). Cobalt concentrations at GW-8 have been trending downward since the peak concentration in April
2019 (97.1 ug/l).

During the First Semi-Annual 2024 event, no NC 2B Surface Water Standards were exceeded in surface
water samples for quantified detections.

Cobalt is naturally occurring at the site, evident by the historical cobalt detections in various wells across
this site, and is a common element occurring naturally in minerals commonly found in the bedrock, soil, and
sediments in the North Carolina Piedmont. Metals in the soil and bedrock can easily leach into the
groundwater, especially if the groundwater is acidic (pH < 7.0). The pH of groundwater samples from the
Upper Piedmont Landfill during the First Semi-Annual 2024 sampling event ranged from 5.06 to 7.26 SU.
The pH of the samples from GW-2, GW-8, and GW-12, which had the highest cobalt concentrations, were
6.17, 5.06, and 5.82 SU, respectively. The pH of the leachate sample was much higher (8.20 SU). The
occurrence and levels of cobalt at the site has no indication of being related to a release from the waste
unit.
9.0 PFAS SAMPLING

In a March 13, 2023 Memorandum (Memo) from DEQ, requirements for per- and polyfluoroalkyl substances
(PFAS) monitoring were outlined. Following discussions with DEQ, the Carolinas Chapter of NWRA and
North Carolina Chapter of SWANA provided an April 28, 2023 recommended Sampling and Analysis
Guidance. This included a recommendation that a subset of representative sample points should be used
to fulfill DEQ’s site screening objectives. In a subsequent July 17, 2023 Memo from DEQ, clarification was
provided regarding the PFAS monitoring. The July 17, 2023 Memo specified PFAS samples should be
collected from each monitoring location for two consecutive events based on a facility’s current water quality
monitoring schedule. Per the July 17, 2023 Memo, facilities with groundwater assessment or corrective
action wells could propose to sample a representative subset of assessment/corrective action wells for
Section review and approval. In addition, the July 17, 2023 Memo stated facilities may propose to collect
samples from a subset of the current surface water sampling locations, comprising at least one upstream
and one downstream location.

In correspondence dated October 2, 2023, the site requested all groundwater sampling points, surface
water sampling points, and leachate sampling points specified in the NCDEQ-approved Water Quality
Groundwater Statistical Analysis Report
Upper Piedmont Regional Landfill, North Carolina 6

Monitoring Plan be sampled for PFAS. There are no assessment or corrective action groundwater
monitoring wells. No underdrain system is currently in place to sample at the site.

During the First Semi-Annual 2024 event, the site collected PFAS samples at each groundwater monitoring
well, surface water monitoring point, and the leachate system. Samples have been analyzed by the
laboratory, and the PFAS results will be submitted to DEQ in a timely manner upon review.

Groundwater Flow Velocity Calculations
Upper Piedmont Regional Landfill
First Semi-Annual 2024 Event

Velocity V = [(k)(i)]/(n) V = [(0.022 ft/day)(0.0596)]/0.075
V = 0.017 ft/day
V = 6.21 ft/year
Where,
Hydraulic conductivity (k) and effective porosity (n) values from the following document: Table 2 of the Second Semi-Annual Water Quality Monitoring Report of 2017, dated
September 25, 2017 by Joyce Engineering.
Gradient (i) is from the average gradient at site using the potentiometric surface map
from Point A to Point B.
Gradient (i) = Change in Groundwater Elevation along Flow Path i: From Point A (680 contour) to Point B (560 contour) = 120 ft / 2015 ft = 0.0596 ft/ft

Non-parametric test used in lieu of parametric prediction limit because the Shapiro Wilk normality test showed the data
to be non-normal at the 0.01 alpha level. Limit is highest of 48 background values. 35.42% NDs. Annual per-
constituent alpha = 0.01903. Individual comparison alpha = 0.0008001 (1 of 2). Assumes 12 future values.
Distribution was found to be non-normal after removal of suspect values, so outliers could not be identified.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPAMethod 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
