WATER QUALITY MONITORING AND CORRECTIVE ACTION INTRODUCTION AND SITE HISTORY
EFFECTIVENESS REPORT — OCTOBER 2022
Battleboro, Nash County
INTRODUCTION AND SITE HISTORY
1.1 Introduction
On behalf of ReUse Technology, Inc. (ReUse), ERM NC, Inc. (ERM) has prepared this Water Quality
Monitoring Report to summarize corrective action activities conducted for the Swift Creek Coal
Combustion By -Products (CCBs) Structural Fill site (CCB-0057) located along U.S. Highway 301 north of
Battleboro, Nash County, North Carolina, (hereafter called the "Site" or "subject property"). Corrective
actions have been implemented at the Site to address groundwater quality impacts in accordance with
the Corrective Action Plan (CAP) (ERM, February 27, 2015) approved by the North Carolina Department
of Environmental Quality (NCDEQ) on March 12, 2015. The corrective actions were implemented in 2017
and included temporary removal of CCB materials to allow raising the floor elevation above the seasonal
high groundwater table, placing the CCB materials on the raised floor in a reduced footprint, installation of
a synthetic liner (cap) over the limits of the CCBs, and drainage improvements to minimize rainfall
infiltration. Groundwater and surface water monitoring activities presented herein are being conducted at
the Site to monitor the effectiveness of the previously completed corrective actions. The Site location is
shown in Figure 1. A Site map is included as Figure 2.
1.2 Summary of Site Environmental History and Corrective Action
The Site consists of a 25-acre property in northeast Nash County bounded by US Highway 301 to the
west, Lane Swamp to the north and east, and Swift Creek to the south. The area surrounding the Site is
comprised of sparsely populated agricultural land and partially wooded land. In December 1991, the
Solid Waste Section approved a proposed plan submitted by ReUse to use CCBs as structural fill
material in the development of the Site as a commercial property. In September 1992, ReUse began
placement of CCBs as beneficial use fill at the Site. In January 2003, the last shipment of CCBs was
accepted at the Site. In March 2003, the Site had been graded, compacted, covered with an 18-inch soil
cap and planted with grass seed. In December 2003, Full Circle Solutions, Inc. purchased the business
assets of ReUse Technology, Inc., including the Swift Creek Site. According to records of Full Circle
Solutions, Inc., a total of approximately 134,000 tons of CCBs were placed at the Site. On November 4,
2004, the Closure Notice was forwarded to the Solid Waste Section.
In August 2004, Sherrill Environmental, Inc. reported the results of groundwater monitoring at four newly
installed monitoring wells (MW-1 S/MW-1 D, MW-2S/MW-2D) at the Site. Lead and sulfate were detected
at concentrations above the respective groundwater quality standards listed in Title 15A North Carolina
Administrative Code (NCAC), Subchapter 2L .0202 (2L standards), effective April 2022, in shallow
groundwater on the east side of the CCB fill. In October 2004, the Solid Waste Section required an
assessment by ReUse to determine the extent of the groundwater impact resulting from the placement of
CCBs at the Site. In March 2006, a Comprehensive Site Assessment for the Swift Creek Project was
submitted to the Solid Waste Section that included the results of an expanded groundwater and surface
water assessment. In September 2006, a Compliance Order was issued by the Solid Waste Section to
ReUse. In December 2006, pursuant to the Compliance Order, an Assessment Monitoring Plan and a
Swift Creek Dewatering Analysis were submitted to the Solid Waste Section. The Assessment Monitoring
Plan described a proposed groundwater and surface water monitoring program for the Site. The Swift
Creek Dewatering Analysis described a proposed dewatering subsurface drain along the western
boundary of the fill along US Highway 301 to remove water from the coal ash fill and lower the local
groundwater table to provide a required minimum 1-foot vertical separation between coal ash and
seasonal high groundwater elevations. The Assessment Monitoring Plan was approved by the Solid
Waste Section in February 2007. The Swift Creek Dewatering Analysis was conditionally approved by the
Solid Waste Section in July 2007 based on the performance of the proposed dewatering plan.

WATER QUALITY MONITORING AND CORRECTIVE ACTION INTRODUCTION AND SITE HISTORY
EFFECTIVENESS REPORT — OCTOBER 2022
Battleboro, Nash County
In January 2008, a dewatering subsurface drain was installed consisting of a 6-inch polyvinyl chloride
(PVC) drain pipe along the western boundary of the fill along US Highway 301. The drain was designed to
lower the local groundwater table to provide a required minimum 1-foot vertical separation between coal
ash and seasonal high groundwater elevations. Groundwater collected in the pipe was transmitted by
gravity flow to an outfall box located at the north end of the Site at Lane Swamp.
The groundwater and surface water monitoring program was initiated at the Site in October 2007 in
accordance with the Assessment Monitoring Plan. The program consisted of semi-annual sampling and
laboratory analytical testing for metals and sulfates at eight groundwater monitoring well locations and
three surface water monitoring locations. Groundwater levels were also measured in the monitoring wells
and piezometers in order to evaluate ground water flow direction and determine water levels relative to
the CCB fill. The reported results of the groundwater monitoring from 2007 to 2014 confirmed
groundwater quality impacts including concentrations of sulfate, arsenic and lead at levels above the
respective 2L standards. The monitoring reported no impacts to surface water quality in Lane Swamp or
Swift Creek adjacent to the facility.
The Division of Waste Management issued a "Warning Notice" to Full Circle Solutions and ReUse dated
May 16, 2014. The notice stated that the required groundwater vertical separation between filled CCBs
and seasonal high groundwater elevations had not been achieved and exceedances of the 2L standards
had been routinely reported. As a result, a "Groundwater Corrective Action Application" was required to
be submitted for approval.
On behalf of Full Circle Solutions and ReUse, ERM submitted a Corrective Action Application, dated
October 16, 2014, to the Division of Waste Management for approval. The Corrective Action Application
proposed the construction of a synthetic liner (cap) and drainage improvements as corrective actions to
significantly reduce or eliminate rainfall infiltration and leachate generation from the beneficial fill. Two
contingency corrective actions also were identified. The Division issued approval in December 2014 and
requested the submittal of a detailed Corrective Action Plan (CAP) to the Solid Waste Section.
The Corrective Action Plan was submitted in February 2015 and approved by the NCDEQ Solid Waste
Section in March 2015. The Corrective Action Plan was designed to raise existing CCBs to above
historically high groundwater levels to prevent the leaching of contaminants of concern from the existing
CCBs. The CAP included the installation of a protective liner system, cover soil layer, and drainage
outlets to prevent infiltration of precipitation into the CCBs to assist in the prevention of leaching. The
footprint of the limits of ash was condensed from approximately 10 acres to 5 acres, reducing the
effective infiltration area. Implementation of the CAP was delayed approximately one year in 2015-2016
due to a North Carolina Department of Transportation (NCDOT) project to realign US Highway 301, along
with bridge replacements across Swift Creek. The corrective measures began on April 24, 2017 and
were completed on January 12, 2018.
In June 2018, two new monitoring wells, MW-5RS and MW-5RD, were installed as replacements for
former upgradient wells MW-5S and MW-5D, which were abandoned in 2015 by the NCDOT as part of
the Highway 301 realignment project. The new wells were located hydraulically upgradient (west) of the
Site on the west side of Highway 301 (see Figure 2) to monitor background water quality in the surficial
aquifer (MW-5RS) and deep aquifer (MW-5RD) zones. The monitoring wells were installed under an
NCDOT right-of-way encroachment agreement (E-0420981800025).
In accordance with the CAP, a performance monitoring and reporting plan was implemented in 2018 to
monitor the effectiveness of the corrective action. The elements of the performance monitoring plan
include:
■ Semi-annual groundwater and surface water monitoring and reporting,

Battleboro, Nash County
■ Quarterly inspection and reporting of the Site for cap structural integrity, erosion control, proper
drainage, etc., and
■ Corrective Action Effectiveness Reports prepared every five years to evaluate and document a
reduction in contaminant concentrations in groundwater and a stable or decreasing plume extent.
2. CONCEPTUAL SITE MODEL
2.1 Hydrogeology
The following updated conceptual site model (CSM) has been developed based on the corrective action
and monitoring work performed by ERM, as well as previous site investigation activities performed by
others.
The Site is located in the Coastal Plain physiographic province of North Carolina. The Site surficial
geology consists of alluvial terrace deposits consisting of layers and mixtures of silts, clay, sands and
gravels. The alluvial deposits at the Site range in thickness from approximately 8 to 16 feet. The shallow
groundwater at the Site occurs in the alluvial deposits and is referred to as the surficial or alluvial aquifer.
The alluvial aquifer sands are of low to moderate permeability (average hydraulic conductivity 0.67
feet/day). Within the alluvial aquifer zone, a yellowish -brown clay layer was encountered in the majority
of the borings for monitoring wells and piezometers installed at the Site. The clay layer of the alluvial
aquifer at the Site is approximately 1 to 4 feet thick and has a low permeability (average hydraulic
conductivity 0.002 feet/day). The clay layer behaves as a confining layer or perching layer, which
appears to limit the vertical migration of contaminants at the Site. On the west (upgradient) edge of the
Site, the clay layer was reported to be absent in the borings for former wells MW-5S, MW-51D, P-23 and
P-24. The alluvial deposits at the Site are underlain by the Yorktown Formation, a regionally extensive
marine deposit. The upper Yorktown Formation, consisting typically of greenish -gray, clayey, silty, Shelly,
very fine sands, is encountered at the Site from approximately 13 feet below ground surface (bgs) to the
maximum depth of investigation of 35 feet bgs, and has a low permeability (average of 0.002 feet/day).
No groundwater quality impacts have been detected in monitoring wells completed in the deeper
Yorktown aquifer zone.
The general groundwater flow pattern at the Site is controlled largely by two groundwater discharge
features: Lane Swamp to the north and east, and Swift Creek to the south. Groundwater flow in the area
of the Site is generally from west to east with a northeast component of flow toward Lane Swamp at the
north end of the Site, and a southeast component of flow toward Swift Creek at the south end of the Site.
2.2 Contaminant Fate and Transport
The key features of the CSM for contaminant fate and transport are summarized as follows:
■ The depth to groundwater ranges from the ground surface at the creeks and swamps to more than 6
feet bgs in topographically higher areas (not including the beneficial fill footprint).
■ The regional groundwater flow regime within the surficial (alluvial) aquifer flows west to east, with
north and south flow components near Swift Creek and Lane Swamp, which serve as shallow
groundwater discharge features.
■ The estimated groundwater velocities at the Site are very low. The historical calculated groundwater
velocities are approximately 6 to 27 feet per year for the surficial (alluvial) aquifer and approximately
0.03 feet per year for the deeper Yorktown aquifer.
■ Prior to the 2018 corrective action, seasonal rises of the underlying water table and rainfall infiltration
downward through the old soil cap resulted in water infiltration into the coal ash fill. Constituents

within the coal ash fill were dissolved by the infiltration water and became mobile. The former
infiltration mechanism has been mitigated by the corrective action.
Once the infiltration water enters the surficial groundwater, it migrates laterally above a clay confining
or perching layer within the alluvial aquifer zone towards the groundwater discharge features of Lane
Swamp and Swift Creek, which serve to limit the lateral extent of the affected groundwater. The
limited lateral extent of the affected groundwater is evident at wells MW-2S and 2D, located
approximately 200 feet east of the former perimeter of the beneficial fill, where groundwater
concentrations are below 2L standards. Similarly, there is no evidence of affected groundwater to
the west (upgradient) as demonstrated by groundwater monitoring results at current monitoring wells
MW-5RS and MW-5RD and former monitoring wells MW-5S and 5D.
■ Based on historical groundwater monitoring results, the groundwater quality impacts at the Site are
limited to the surficial aquifer zone. No groundwater quality impacts are detected in the deeper
aquifer zone of the Yorktown Formation.
The swamps and creeks surrounding the beneficial fill site act as a "natural perimeter drain" and
intercept the affected groundwater. Based on the historical surface water monitoring results, there
are no surface water quality impacts to Lane Swamp or Swift Creek due to affected groundwater from
the Site.
3. WATER QUALITY MONITORING ACTIVITIES
3.1 Objectives
Demonstration of effectiveness of the completed remediation is the primary objective of the water quality
monitoring program (i.e., remedial performance monitoring). This objective is achieved by monitoring the
reduction of the site -specific contaminants of concern (COC) in groundwater, therefore mitigating the
potential for surface water quality impacts due to contaminated groundwater migration and discharge to
surface water.
The applicable preliminary remedial goals for groundwater and surface water are summarized in the
following table.

measured for each groundwater and surface water sample by calibrated meters. Well purge logs were
completed for each monitoring well to document the stabilization of field parameters prior to sample
collection. Well purge logs included in the Field Data Sheets provided in Appendix B. The groundwater
and surface water samples were placed in laboratory supplied containers and placed on ice. The samples
were submitted to North Carolina certified laboratory Pace Analytical Services (Formerly Shealy

4. MONITORING RESULTS
4.1 Groundwater Monitoring Results
Groundwater monitoring activities were conducted at 11 monitoring wells at the Site. Groundwater depth -
to -water gauging and elevation data are presented in Table 2. The groundwater elevations in the surficial
aquifer on October 19, 2022 ranged from 89.78 feet above mean sea level (ft MSL) at MW-6 located on
the east (downgradient) side of the Site to 92.95 ft MSL at MW-4 located on the west (upgradient) side of
the Site. The groundwater elevations are below the base of the CCB fill, which generally ranges from 94
to 99 ft MSL from east to west. A potentiometric surface map for the surficial (alluvial) aquifer zone for the
October 2022 monitoring event is presented as Figure 3. Groundwater flow in the surficial aquifer over
most of the Site is generally west to east towards Lane Swamp Swift Creek, which serves as a
groundwater discharge zone.
Using the current groundwater elevation data, the hydraulic gradients for the Site were calculated and are
summarized in the following table.

Sulfate, a primary indicator analyte for CCB contaminant releases, was detected in groundwater at
concentrations above its 2L standard (250 mg/L) at five of the 11 monitoring wells. The distribution of
sulfate concentrations across the Site is depicted in Figure 5. A hydrogeologic profile across the Site,
including sulfate concentrations in groundwater, is presented in Figure 6. The highest concentration of
sulfate was detected in the groundwater sample collected from monitoring well MW-7 (680 mg/L) located
on the eastern (downgradient) side of the Site; however, the sulfate concentration (650 mg/L) in the
sample collected from the furthest hydraulically downgradient monitoring well (MW-8) is slightly lower.
Graphs of sulfate concentrations over time for selected monitoring wells are presented in Figure 7. Since
the completion of the corrective action in January 2018, the graphs indicate fluctuating but overall
decreasing sulfate concentration trends at MW-3, MW-6, MW-7 and MW-8, where the most elevated
sulfate levels have historically been observed.
Notably low values of pH were measured in the groundwater samples from MW-6 (3.5), MW-7 (3.5), and
MW-8 (3.7). The low pH values at the three wells are consistent with historical monitoring results, and
correlate with detections of arsenic and lead, in addition to sulfate, at concentrations above their
respective North Carolina 2L groundwater standards at the three wells.
There were no exceedances of 2L standards in the groundwater samples collected from monitoring wells
MW-5RS and MW-5RD located on the west (upgradient) side of the Site, nor in the sample collected from
monitoring well MW-4, located near the southwest limit of the CCB fill area. The groundwater sample
collected from monitoring well MW-4 exhibited an exceedance of the 2L standard for arsenic during the
November 2021 monitoring event, which was not consistent with historical sampling events. The
groundwater sample collected from monitoring well MW-4 during the October 2022 event was again
below the 2L standard for arsenic. Historically, there have been no detectable levels of arsenic at MW-4
since 2010, with exception of the anomalous result from the November 2021 event.
On the east side of the Site, sulfate and TDS concentrations exceeded their 2L standards in groundwater
samples collected from MW-1S, which is consistent with historical monitoring results. The only other
exceedance of the 2L standards detected in samples from the four monitoring wells located on the east
side of the Site (MW-1 D, MW-1 S, MW-2S and MW-21D) was a concentration of TDS in MW-1 D. The
elevated TDS concentration at MW-1 D does not appear to be attributable to sulfate or metals, which were
not present at elevated levels.
Sulfate and TDS concentrations in the groundwater sample collected from well MW-3, which is located on
the central portion of the Site along the southern limit of the CCB fill area, exceed their 2L standards. This
is consistent with historical monitoring results.
4.2 Surface Water Monitoring Results
Consistent with historical monitoring results, all October 2022 surface water monitoring results were
below the respective North Carolina 213 surface water standards for samples collected from Swift Creek
(SW-1) and Lane Swamp (SW-2 and SW-3). The October 2022 surface water sampling results are

summarized in Table 3. Laboratory analytical reports for the surface water samples are provided in
Appendix C. Historical surface water data is summarized in Appendix A.
4.3 Laboratory Data Quality Analysis
Quality assurance/quality control (QA/QC) samples collected during the October 2022 groundwater
sampling activities included one blind duplicate sample collected at MW-1S. The duplicate and parent
sample results for MW-1S can be compared in Table 3. The analytical results of the MW-1S and
duplicate groundwater samples compare favorably, indicating no analytical discrepancy.
5. SUMMARY
Corrective actions have been implemented at the Site to address groundwater quality impacts in
accordance with the approved CAP. The corrective actions were completed in January 2018 and included
temporary removal of CCB materials to allow raising the floor foundation above the seasonal high
groundwater table, placing the CCB materials on the raised floor in a reduced footprint, installation of a
synthetic liner (cap) over the limits of the CCBs, and drainage improvements to minimize rainfall
infiltration. Groundwater and surface water monitoring activities are being conducted at the Site to monitor
the effectiveness of the previously completed corrective actions.
The October 2022 water quality monitoring event was conducted to evaluate groundwater and surface
water quality at the Site approximately 4.8 years after corrective action implementation. Since the
completion of the corrective action in 2018, the 4 monitoring wells (MW-3, MW-6, MW-7 and MW-8)
historically exhibiting the greatest sulfate concentrations in groundwater continue to exhibit overall
decreasing trends as shown in Figure 7. The trend of decreasing sulfate concentrations indicates that the
corrective action is effectively mitigating groundwater quality impacts at the Site. The October 2022
surface water quality results continue to demonstrate that there have been no surface water impacts to
Swift Creek or Lane Swamp due to discharges of affected groundwater from the Site.
In accordance with the CAP, semi-annual water quality monitoring will continue at the Site, with the next
monitoring event tentatively planned for April 2023.

XJ21051-011 yielded high residual mass for TDS analysis. The sample yielded 0.4651 grams of residue.
The SOP states the working range is 0.0025-0.200g. The balance is verfied up to 150g each analytical
day.
The following samples exceeded the TDS upper weight limit of 0.2g for residual mass as outlined in the
SOP: XJ21051-001 (0.7482g), XJ21051-009 (0.5069g), XJ21051-010 (0.9576g). 100mL(max) of sample
volume was filtered for each of these samples.
The following samples had an initial analysis for Sulfate outside of analytical holding time due to
laboratory error: XJ21051-007, XJ21051-008, XJ21051-011, XJ21051-014.
Reanalysis of the following sample was performed outside of the analytical holding time: XJ21051-004.
XJ21051-009 was analyzed three times. In the first two analyses, the results were over range. The third
analysis out of holding time was diluted and the result is within range. The results are as follows in order
from run 1 to run 3: 650mg/L, 680mg/L, 790mg/L. The initial in -hold data has been reported.
