Groundwater Statistical Analysis Report
Foothills Regional Landfill, North Carolina 1
1.0 INTRODUCTION
On behalf of Foothills Regional Landfill, Jett Environmental Consulting statistically evaluated the First Semi -
Annual 2019 water quality monitoring data. Groundwater, surface water, underdrain, and leachate
sampling were completed by Environmental Sampling & Services, Inc. (ES&S) on January 28, 2019, and
analytical testing was performed by Pace Analytical Services, LLC. The statistical analysis software
package utilized, Sanitasr', 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
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 2019 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.
The facility's monitoring network is comprised of ten monitoring wells: MW-1 R2 (background), MW-2R,
MW-3R2, MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, and MW-11, which monitor the uppermost
aquifer beneath the facility. The monitoring wells are sampled on a semi-annual basis, with the groundwater
samples submitted to a qualified laboratory for required analyses in accordance with the facility's
environmental monitoring program and permit requirements. 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 of the wells was sampled during the First Semi -Annual
2019 event in January 2019.
Groundwater monitoring was initiated in August 1998. Statistical background is defined as samples
collected from former upgradient well MW-1, former upgradient well MW-1 R, and current upgradient well
MW-1 R2 from 1998 through the current 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".
In addition, in a May 29, 2018 memorandum, DEQ requested groundwater and surface water samples be
analyzed for 1,4-dioxane. Therefore, the groundwater and surface water samples were analyzed for 1,4-
dioxane initially during the July 2018 event and also during the January 2019 event.
Recent soil and bedrock removal in the Northern Borrow Area rendered well MW-1 R dry and inaccessible.
Therefore, a replacement monitoring well (MW-1 R2) was installed in September 2018. New well MW-11
was also installed in September 2018 as part of the Cell No. 5B construction. A Groundwater Monitoring
Well Installation Report dated October 19, 2018 was compiled by Bunnell Lammons Engineering Inc. and
submitted to DEQ by the site. The two new wells have been sampled on September 11, 2018 (n=1),
October 8, 2018 (n=2), December 3, 2018 (n=3), and January 28, 2019 (n=4).
Well MW-3R2 was added to the monitoring well network on August 17, 2006 as a replacement well for
MW-3 and MW-3R. Monitoring wells MW-3 and MW-3R remain for water level data collection purposes
only. Monitoring well MW-7 was installed in April 2010 to monitor groundwater beneath Cell 4, which began
receiving waste in September 2010. MW-8 was installed in April 2013 to monitor Cell 8A, which was
constructed in January 2013. MW-10 was installed in October 2015 to monitor Cell 5A. The former
background well MW-1 was abandoned in preparation for construction of Cell 5A and the new background
well, MW-1 R, was installed in October 2015. MW-9 was installed June 2016 to monitor Cell 5A.

Foothills Regional Landfill, North Carolina 2
The site has a surface water monitoring network consisting of one upstream surface water sampling point
(SW-1) and three downstream points (SW-2, SW-3, and SW-4). These points are sampled semi-annually
for the 40 CFR Part 258 Appendix I list in conjunction with the groundwater monitoring wells. Per the DEQ
May 29, 2018 memorandum mentioned above, these points were also sampled for 1,4-dioxane this event.
Each surface water monitoring point was sampled during the First Semi -Annual 2019 event.
A sample from the underdrain for Cell 1 (UD-1) was added to the monitoring network prior to the January
2008 sampling event. A sample from the underdrain for Cells 4 and 8A (UD-2) was added to the monitoring
network prior to the January 2014 sampling event. The underdrains are to be sampled semi-annually
(contingent on flow availability) for the 40 CFR Part 258 Appendix I list. Both underdrains were able to be
sampled during the First Semi -Annual 2019 event.
A leachate sample is also routinely collected for analysis. The Ieachate sample was analyzed for the 40
CFR Part 258 Appendix I list, biochemical oxygen demand, chemical oxygen demand, nitrate as N, nitrite
as N, phosphorous, and sulfate.
The facility was in an Assessment Monitoring Program in 2006. An Alternate Source Demonstration (ASD)
for volatile organic compounds (VOCs) detected in wells MW-3 and MW-31R was approved by DEQ on
December 14, 2006, and the facility reverted to a Detection Monitoring Program.
An ASD for cobalt and a request to use background as the groundwater protection standard (GWPS) for
cobalt was submitted to the DEQ in November 2016. The ASD is currently under DEQ review.
An ASD for benzene and vinyl chloride at MW-2R was submitted to DEQ in June 2017; however, it was not
approved in a letter from DEQ dated October 11, 2017 and Assessment Monitoring was initiated.
Therefore, during the First Semi -Annual 2018 event, the initial Appendix II Assessment constituent list was
sampled at each well. The constituents detected at quantifiable concentrations (barium, benzene, and
cobalt) were consistent with past events and also on the Appendix I Detection Monitoring list. On
May 18, 2018, the site requested deleting all non -Appendix I monitoring from future sampling events, with
the exception of well MW-2R, which will continue with annual Appendix II monitoring. In correspondence
dated July 9, 2018, DEQ approved the request to only include MW-2R for future annual Appendix II
monitoring. The annual Appendix II monitoring for MW-2R was performed during January 2019 sampling
event. No Appendix 11 constituents, not also on the Appendix I list, were detected above their respective
PQLs during the January 2019 event. The next annual Appendix 11 sampling event for MW-2R will be
January 2020.
3.0 SITE HYDROGEOLOGY
The following site hydrogeology summary was taken from the Second Semi -Annual Water Quality
Monitoring Report of 2017, dated November 17, 2017 by Joyce Engineering.
Geologically, the facility is located in the northwestern portion of the Inner Piedmont Belt of the Piedomont
Physiographic Province, approximately 20 miles east of the thrust belt (Brevard Shear Zone) delineating
the boundary between the westerly Blue Ridge Belt and the easterly Inner Piedmont Belt. The metamorphic
rocks of the Inner Piedmont Belt generally group within the sillimanite facies of the amphibolite metamorphic
sequence. Locally, the bedrock underlying the facility has been mapped as migmatitic granitic gneiss of the
Ordovician and older Cambrian Periods. These rocks are described as ranging in composition from granitic
to quartz dioritic with smaller biotite gneiss and amphibolite facies present locally. The unit as a whole
exhibits a variable massive to foliated fabric.
The uppermost aquifer beneath the facility is present within weathered bedrock saprolite and fractured
bedrock. The saprolite ranges in texture from clayey silt in the upper, most weathered sections to micaceous
sandy silt in the lower sections. Immediately above the competent bedrock surface, a variable thickness
transitional zone composed of highly weathered and degraded friable bedrock is present.

Groundwater Statistical Analysis Report
Foothills Regional Landfill, North Carolina 3
The uppermost aquifer is laterally continuous across the site, with depth to water ranging from less than 31
feet in low-lying areas to greater than 77 feet beneath topographic highs. Groundwater in the uppermost
aquifer generally flows from recharge areas associated with broad gently sloping topographic areas towards
topographically lower areas that are generally delineated by the presence of stream channels, some of
which are perennial receiving streams (groundwater discharge areas) and others of which are intermittent
discharging streams. In the vicinity of the facility, the general groundwater flow direction is towards the
south and west.
Appendix A provides a potentiometric surface map utilizing groundwater level data from the First Semi -
Annual 2019 event. Groundwater flow direction for the First Semi -Annual 2019 event was to the southwest,
which is consistent with previous interpretations for this facility. The First Semi -Annual 2019 event
groundwater flow direction was consistent with past events. Groundwater flow rate for the First Semi -
Annual 2019 event was estimated at 180 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 2019 groundwater, surface water, underdrain, and leachate sampling event. Also included in
Appendix C is a copy of the laboratory analytical reports and field sampling forms for the September 11,
2018 (n=1), October 8, 2018 (n=2), December 3, 2018 (n=3), and January 28, 2019 (n=4) events for new
wells MW-1 R2 and MW-11. .
The analytical results for the First Semi -Annual 2019 event for the groundwater, surface water, underdrain
and leachate samples are summarized on Tables 2, 3, and 4, respectively. One volatile organic compound
(VOC) was detected at a quantified concentration above a laboratory practical quantitation limit (PQL) in
groundwater samples: benzene at MW-2R. As shown on Table 2, two Appendix I inorganic constituents
(barium at MW-2R, MW-5, and MW-6; and cobalt at MW-4, MW-6, and MW-8) were detected at quantified
concentrations.
Two Appendix I constituents (benzene at MW-2R; cobalt at MW-4, MW-6, and MW-8) were detected above
an NC Interim Maximum Allowable Concentration (IMAC) or 2L Standard during the First Semi -Annual 2019
sampling event. Vanadium (MW-1 R, MW-5, and MW-10) was detected above their respective IMAC,
however at estimated concentrations below their PQL.
As shown on Table 3, during the First Semi -Annual 2019 event, no NC 2B Surface Water Standards were
exceeded in surface water or underdrain samples. No VOCs were detected in surface water or underdrain
samples at quantified concentrations above their respective PQLs during the First Semi -Annual 2019 event.
Groundwater and surface water samples were analyzed for 1,4-dioxane this event according to the request
in the May 29, 2018 DEQ memorandum noted above. There were no detections of 1,4-dioxane in the
January 2019 groundwater and surface water samples.
The constituents detected in the leachate sample collected during the First Semi -Annual 2019 event are
typical for leachate at this facility.
5.0 STATISTICAL PROCEDURES
Statistical analyses (i.e. inter -well prediction limits) were performed to establish background concentrations
and determine if the IMAC value -to -value exceedances for cobalt exhibited a statistically significant
increase. Statistical analyses (i.e., lower confidence limits) were performed to determine if the 2L Standard
value -to -value exceedance for benzene statistically exceeded the 2L Standard.

Groundwater Statistical Analysis Report
Foothills 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 EPA document, Statistical Analysis of Ground -Water Monitoring Data
at RCRA Facilities — Unified Guidance (March 2009). Any statistical outliers that were determined were
removed from the background data set prior to performing prediction interval statistical analysis. According
to the EPA guidance documents above, 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.
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.
For the First Semi -Annual 2019 event, three inorganic statistically significant increases were exhibited for
the groundwater monitoring wells: cobalt at MW-4, MW-6, and MW-8. The First Semi -Annual 2019
concentrations of total cobalt at MW-4 (19.7 ug/L), MW-6 (11.0 ug/L), and MW-8 (10.2 ug/L) were above
the background inter -well prediction limit based on pooled data from upgradient wells MW-1, MW-1 R, and
MW-1 R2 (10 ug/L, which is equal to the PQL).
An ASD for cobalt at MW-4 and a request to use background for the GWPS was submitted to the DEQ by
the site on November 4, 2016. The statistical background value for cobalt was determined to be 44.1 ug/L
based on an Upper Poisson Prediction Limit, which is higher than the detected concentration at MW-4,
MW-6, and MW-8. The ASD requested that the background value be considered the GWPS for cobalt per
15A NCAC13B.1634.(g).5. The ASD is currently under DEQ review.
5.3 Intra-Well Confidence Limits
Per DEQ Regulation .1634(H), Groundwater Protection Standards (GWPSs) are equal to the National
Primary Drinking Water Standard -Maximum Contaminant Level (MCL) or North Carolina 15A NCAC 2L

Groundwater Statistical Analysis Report
Foothills Regional Landfill, North Carolina 5
Water Quality Standard, whichever is lower. In instances where an MCL or 2L Standard are not established,
the GWPSs were derived from the DEQ-Solid Waste Section published GWPSs.
In order to determine if the groundwater concentrations exhibit a statistical exceedance of the GWPS, a
statistical comparison was made to the GWPSs to determine if further action is warranted. The following
text outlines the procedures that were used to statistically compare concentrations to GWPSs.
Per the U.S. Environmental Protection Agency document (dated March 2009), titled Statistical Analysis of
Groundwater Monitoring Data at RCRA Facilities, Unified Guidance, a Confidence Interval is constructed
from sample data and is designed to contain the mean concentration of a well analyte in groundwater
monitoring, with a designated level of confidence. A confidence interval generally is used when samples
are being compared to a GWPS, which is typically the MCL or alternate concentration limit (i.e. 2L Standard
or NC IMAC).
A lower confidence interval analysis was used to statistically compare to GWPSs. The method constructs
a normal confidence interval on the mean concentration of a constituent incorporating, at a minimum, the
four most recent measurements. The lower confidence interval on the mean was compared to the GWPS
to determine whether the mean concentration exceeded its GWPS. If the lower confidence interval on the
mean exceeds the GWPS then there is statistically significant evidence that the mean concentration of that
constituent exceeds the GWPS.
The distribution of the data is evaluated by applying the Shapiro -Wilk or Shapiro-Francia test for normality
to the raw data or, when applicable, transformed data. If less than 15 percent of the observations are non -
detects, the non -detects will be replaced with one half the reporting limit prior to performing the normality
test and constructing the confidence limit.
Per .1634(g)(5), if background (statistical limit based on upgradient well data) is higher than the 2L
Standard, then background may be utilized as the GWPS. Background for organics is considered the non -
detect level (equivalent to the PQL).
Organic concentrations detected above PQLs and GWPSs (See Table 2) were statistically compared to
their respective GWPSs utilizing intra-well lower confidence limits. As provided in Appendix B, benzene
at MW-2R statistically exceed the GWPS for the First Semi -Annual 2019 event. Time series graphs for
VOC detections during recent events are provided in Appendix B. As shown on Table 2, the January 2019
benzene result for MW-2R (1.6 ug/L) confirmed the GWPS (1.0 ug/L) exceedance.
5.4 Statistical Results Summary
For the First Semi -Annual 2019 event, three inorganic statistically significant increases were exhibited for
the groundwater monitoring wells: cobalt at MW-4, MW-6, MW-8. The First Semi -Annual 2019
concentrations of total cobalt at MW-4 (19.7 ug/L), MW-6 (11.0 ug/L), and MW-8 (10.2 ug/L) were above
the background inter -well prediction limit based on pooled data from upgradient wells MW-1, MW-1 R, and
MW-1 R2 (10 ug/L, which is equal to the PQL).
Intra-well lower confidence limits determined benzene at MW-2R statistically exceed the GWPS for the First
Semi -Annual 2019 event. However, benzene concentrations at MW-2R has decreased during the last two
semi-annual events (July 2018 and January 2019).
6.0 CONCLUSIONS
For the First Semi -Annual 2019 event (January 2019), one inorganic statistically significant increase was
confirmed exhibited for the groundwater monitoring wells: cobalt at MW-4. Two new inorganic statistically
significant increases were exhibited for the groundwater monitoring wells: cobalt at MW-6 and MW-8. The
January 2019 cobalt concentrations at MW-6 (11.0 ug/L) and MW-8 (10.2 ug/L) were only slightly above
the laboratory PQL (10 ug/L).

Groundwater Statistical Analysis Report
Foothills Regional Landfill, North Carolina 6
One VOC was detected at a quantified concentration above a 2L Standard in groundwater samples during
the First Semi -Annual 2019 event: benzene at MW-2R. Intra-well lower confidence limits determined
benzene at MW-2R statistically exceed the GWPS for the First Semi -Annual 2019 event.
During the First Semi -Annual 2019 event, no Appendix I VOCs were detected in surface water and
underdrain samples at quantifiable concentrations. No verified detections of Appendix I metals exceeded
NC 2B Surface Water Standards for surface water and underdrain points during the First Semi -Annual 2019
event.
The annual Appendix II monitoring for MW-2R was performed during the January 2019 sampling event. No
Appendix II constituents, not also on the Appendix I list, were detected at MW-2R above their respective
PQLs.
Groundwater and surface water samples were collected for 1,4-dioxane this event according to the request
in the May 29, 2018 DEQ memorandum noted above. This parameter is not specified in the rules or
approved monitoring plan. The First Semi -Annual 2019 event was the second consecutive event with no
1,4-dioxane detections. Per a November 28, 2018 DEQ letter, if 1,4-dioxane was reported as non -detect
in January 2019, then the site could cease monitoring of the groundwater and surface water samples for
1,4-dioxane. In accordance with the November 28, 2018 DEQ letter, 1,4-dioxane will no longer be analyzed
for the groundwater and surface water samples, however will be analyzed annually for the leachate sample.
The Foothills Regional Landfill will continue monitoring in accordance with the requirements for Detection
and Assessment Monitoring as outlined in Title 15A NCAC 13B .1633 and .1634, respectively. The next
semi-annual event is scheduled for July 2019.
7.0 RECOMMENDATIONS
Wells in the proximity of MW-2R exist directly upgradient (MW-9) and directly downgradient (MW-3R2). No
VOCs have been detected at quantified concentrations at MW-9 or MW-3R2; therefore, the extent of
quantified VOC detections (i.e. benzene) has been defined to only MW-2R.
As described in the site's June 2017 ASD for benzene/vinyl chloride at MW-2R, the VOCs appear to be
related to landfill gas. Wells MW-9, MW-2R, and MW-3R2 would effectively cover the exterior perimeter of
the cell (1A) suspected as the source of potential gas migration. The site implemented landfill gas extraction
and collection upgrades in the Cell 1A area in late 2017 and installed a horizontal landfill gas
collection/mitigation trench in the vicinity of MW-2R in Fall 2018. An additional event or two of groundwater
monitoring is recommended before any further actions to determine if benzene levels at MW-2R (1.6 ug/L)
decrease to levels below the lab PQL (1.0 ug/L) as a result of the landfill gas system upgrades.
It is recommended that wells MW-4, MW-6, and MW-8 continue in Detection Monitoring. The drop of cobalt
at MW-4 from 25.4 ug/L in July 2012 to 19.7 ug/L in January 2019, indicates a slow decreasing trend near
the laboratory PQL (10 ug/L). The January 2019 cobalt concentrations at MW-6 (11.0 ug/L) and MW-8
(10.2 ug/L) were only slightly above the laboratory PQL (10 ug/L). The first time trace level exceedances
of cobalt at MW-6 and MW-8 will be verified during the July 2019 event.
In summary the January 2019 cobalt results are very close to the background statistical limit. Since the
landfill is lined, it is unlikely the cobalt detections are related to a landfill release. The concentrations are
expected to naturally attenuate to levels well below background with minimal migration distance. The lack
of receptors of water use in this shallow well, which would not feasibly produce a well with sufficient yield
for potable use, is evidence of a lack of risk associated with this level of detection.
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. According to A Geochemical Atlas of North Carolina (by Jeffery
C. Reid, dated 1993 in the North Carolina Geological Survey's Bulletin 93), which displays the distribution

Groundwater Statistical Analysis Report
Foothills Regional Landfill, North Carolina 7
of cobalt in stream sediments across the state, Caldwell County has been highlighted. Cobalt was found at
concentrations as high as 10 mg/kg throughout Caldwell County; with a significant amount of variability.
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 Foothills Landfill during the January 2019 sampling
event ranged from 5.58 to 7.20 SU, and the pH of the sample from MW-4, which had the highest cobalt
concentration, was 5.23 SU. Review of leachate data for the last 10 years indicates cobalt has ranged from
<10 to 33.2 ug/L, with an average concentration of 21.9 ug/L. The occurrence and levels of cobalt at the
site has no indication of being related to a release from the MSWLF unit.
The site recommends utilizing the upcoming July 2019 event to continue to verify the downward trend of
cobalt levels at MW-4 and benzene at MW-2R, since both levels are so close to the laboratory PQL of 10
ug/L and 1.0 ug/L, respectively. The July 2019 event will also be utilized to verify the trace level cobalt
detections at MW-6 and MW-8. The proposed actions are protective of human health and the environment
and the values at this time do not further action, especially for a naturally occurring element (cobalt).

Groundwater Flow Velocity Calculations
Foothills Regional Landfill
First Semi -Annual 2019 Event
Velocity
V = [(k)(i)]/(n)
V = [(0.374 ft/day)(0.1317 ft/ft)] / 0.1
V = 0.493 ft/day
V = 180 ft/year
Where,
Hydraulic conductivity (k) and effective porosity (n) values from the following document:
Table 2 of the Second SemiAnnual Water Quality Monitoring Report of 2017, dated
November 17, 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
is From Point A (1500 contour) to Point B (1150 contour) = 350 ft / 2,657 ft = 0.1317 ft/ft
