Hydrogeological Conceptual Site Model Update —Badin Business Park
���
Executive Summary
Executive Summary
The revised hydrogeological conceptual model for the Badin Business Park presented in this document is
based on a synthesis of historical information and studies along with data from field studies performed
as recently as 2022. The primary finding is that groundwater at the former Main Plant is recharged from
precipitation infiltrating into partially weathered rock on the hillside to the west, and from Badin Lake to
the east. Groundwater travels through the partially weathered rock unit to ultimately discharge
primarily on the floodplain of Little Mountain Creek. Whereas other soil and fill units exist, they are
limited in extent and capacity to transmit groundwater over broad areas.
Plume geometry at the former Main Plant is constrained by the distribution of native soil, fill derived
from native soil, and fill derived from a mixture of native soils and anthropogenic debris that includes
industrial materials. The location and geometry of the plume has remained stable to decreasing over the
time between the most recent Site -wide investigations. Groundwater migration out of these fill areas is
limited by the hydraulic properties of the surrounding geologic units. Geochemical attenuation of
constituents of interest occurs through mixing with clean water from Badin Lake that is recharging the
partially weathered rock groundwater system, and through mineralization reactions that occur due to a
large pH gradient.
The aged stormwater conveyance network contains discontinuities such that groundwater enters the
portion of the Outfall 005 stormwater system in localized areas where pipes intersect the partially
weathered rock. This water ultimately discharges at Outfall 005 and results in periodic fluoride
exceedances above the National Pollutant Discharge Elimination System (NPDES) discharge limit criteria.
Remediation measures implemented at the toe of the Alcoa/Badin municipal landfill are demonstrated
to be effective at capturing impacted groundwater and preventing migration of constituents of interest
to Little Mountain Creek. Ongoing data collection from this area during 2023 will be used to update and
further validate this hydrogeological conceptual model in future submissions.

Introduction
1 Introduction
This revised Hydrogeological Conceptual Site Model (HCSM) Report (Report) has been prepared for
Badin Business Park LLC, a subsidiary of Alcoa Corporation (Alcoa). The Badin Business Park Facility
(Facility or Site), formerly known as the Badin Works Facility and associated properties, consists of the
former Main Plant, Alcoa Badin Landfill (ABL), and Old Brick Landfill (OBL). The Facility is located at 293
Highway 740 in Badin, Stanly County, North Carolina. This report has been developed out of a need to
update the understanding of conditions at the Facility and to guide remedial actions. It is based on a
synthesis of historical information and studies along with data from field studies performed as recently
as 2022. This report provides an updated assessment of the hydrogeology, the interaction between
groundwater and surface water, and contaminant attenuation across the former Main Plant and ABL.
The results and conclusions of this report include a summary of additional works completed during 2022
to address identified data gaps in order to meet the stated objective. The 2022 data are supplemented
with historical stormwater sampling results; historical Facility reports and data; United States Geologic
Survey (USGS) and North Carolina Geological Survey (NCGS) maps, publications, and geospatial data
products; peer -reviewed research; re-evaluation of Site -related well lithology, water level monitoring,
and laboratory analytical data; and geospatial data products produced from these data sources.
Furthermore, as part of this scope of work for the supplemental investigations, reinterpretation of
historical investigation data through a review of published literature was used to update the HCSM and
align it with recognized key concepts of the hydrogeology and flow systems pertinent to Piedmont
geology, including the Heath Le Grande Model (LeGrand, 1967, 2004). This required a greater emphasis
(consistent with the LeGrand model) on the physical properties and flow within the partially weathered
rock (PWR), which is recognized as the primary geologic unit controlling groundwater flow and flux in
this type of geologic setting.
The remainder of this Report is structured as follows:
• Introduction and Key Findings (Section 1)
• Background (Section 2)
• Investigation Activities (Section 3)
• Regional Setting (Section 4)
• Site Geology (Section 5)
• Site Hydrogeology (Section 6)
• Geochemistry (Section 7)
• Stormwater System (Section 8)
• ABL-Specific Hydrogeology and Efficacy of ABL Corrective Measures (Section 9)
• Conclusions (Section 10)
• References (Section 11)
1.1 Key Findings
This report provides an update to the understanding of the HCSM. Prior to Facility development,
groundwater flowed according to natural geologic controls typical of the North Carolina Piedmont
(Figure 1-1). A key difference between the Facility and natural flow systems is that excavation for
development removed native soils over a large portion of the former Main Plant, and Badin Lake was

Hydrogeological Conceptual Site Model Update — Badin Business Park
Introduction
Additional key findings of the refined HCSM and supporting data collected in 2022 are summarized in
the following bullet points.
• Geologic units at the Facility are PWR including fractured rock, saprolite and residual soil, and
fill. Fill is either composed of native soils or is a mixture of native soil and anthropogenic debris
that includes industrial materials.
Groundwater occurs in PWR (including fractured rock) and anthropogenic fill.
o Saprolite and residual soil have very low hydraulic conductivity; no monitoring wells are
exclusively screened in these units. Monitoring wells that include saprolite or residual soil in
the screen interval only produce water if the screen interval also intersects fill or PWR.
o Fill has highly variable hydraulic conductivity depending on the proportion of native soils. A
higher proportion of fill made up of native soils equates to lower hydraulic conductivity.
o PWR has moderate hydraulic conductivity and is locally very conductive due to fracturing.
Evidence for high local permeability is a significant loss of drilling fluid circulation during
drilling of MW-20A (Geraghty and Miller, 1995).
PWR and fractured rock are the only units that are continuous across the former Main Plant and
ABL. Areas of fill are limited to isolated ravines or drainages that were filled during Facility
development and operations, consequently:
o A network of PWR wells is critical for understanding groundwater fate and transport.
o Wells screened in fill are only useful for understanding how isolated areas of fill interact
with the broader PWR groundwater system.
• Based on groundwater elevation data, groundwater in PWR at the former Main Plant is
recharged by Badin Lake to the east and a flow system originating on the hillside to the west.
The two flow systems converge near the shoreline of Badin Lake and flow southward toward the
ABL. Groundwater ultimately discharges primarily to the floodplain of Little Mountain Creek, as
evidenced by strong upward vertical groundwater gradients in this location.
• Mixing between Badin Lake water and groundwater leads to substantially lower constituent
concentrations due to mixing and geochemical attenuation across a steep pH gradient at the
mixing zone.
• Groundwater flow directions in PWR are influenced by the regional trend of geologic structures
and subsurface stormwater infrastructure, both of which trend northeast -southwest in the
direction from Badin Lake toward the floodplain of Little Mountain Creek.
• Limited sections of storm sewer piping intersect the PWR and groundwater contained in this
unit and the groundwater from this system has been shown to enter stormwater sewers.
Fluoride enters the storm sewer system where the pipe intersects PWR or fractured rock. This
water ultimately exits at Outfall 005. The introduction of clean water to the storm sewer could
bring the system into compliance.
• The storm sewer systems were established in natural materials and the use of bedding materials
was limited before pipe placement. The intermittent distribution of bedding materials (sand,
gravel, etc.) limits the potential for preferential flow of groundwater along these trench lines.
Groundwater gauging data does not show any distortions in groundwater equipotential (low
groundwater elevations proximal to drain infrastructure), which would be indicative of
preferential flow along bedding materials.
• A groundwater collection trench at the toe of the ABL has gone through several upgrades and is
effective at mitigating groundwater impacts to the floodplain of Little Mountain Creek. The
efficacy of the interceptor trench is monitored by annual geophysical surveys of subsurface
conductivity, which indicates a decreasing footprint of impacted groundwater.

>_ Background
Areas where past operations occurred include the 123-acre former Main Plant, and industrial materials
were disposed of in the 14-acre ABL located 500 feet southwest of the former Main Plant, and the 3-
acre OBL located 0.75 miles northeast of the former Main Plant (Figure 2-1).
The former Main Plant was built on an area of engineered cut and fill that was leveled to an elevation of
approximately 520 feet relative to the North American Vertical Datum 1988 (NAVD88) (Figure 2-1). The
elevation increases immediately east of the Facility to over 600 feet NAVD88. The former Main Plant is
bordered by Badin Lake to the east, which is a man-made flooded valley constructed in the early 1900s
for generating hydroelectric power. The average surface water elevation of Badin Lake is approximately
509 feet (NAVD88) based on data from the Cube HydroT"' Carolinas websitel(corrected for obvious
outliers). The ground surface elevation decreases south of the former Facility and ABL to less than 470
feet NAVD88 on the floodplain of Little Mountain Creek.
Note: Yellow dashed lines indicate ground elevation in units of feet (North American Vertical Datum 1988 [NAVD88]).

Background
2.1 Operational History
The Facility operated from 1916 through 2007 after Badin Lake was constructed in the early 1900s for
hydroelectric electricity generation. In the mid-1960s, potlines were redesigned and expanded at the
Facility. Production output was lowered in August 2002, and only anodes and high -purity aluminum
were manufactured until production ceased in 2007. The Facility was permanently closed in 2010.
Several buildings have been demolished since 2012, and the former Facility has been redeveloped into a
business park for manufacturing companies.
2.2 Sources of Contamination and Constituents of Interest
The Facility employed the Hall-Heroult industrial aluminum smelting process, which involved high -power
electrolytic extraction of aluminum from a cryolite solution containing sodium, alumina, and fluoride.
The process was conducted in brick -lined steel pots, with an inner lining of carbon -based cathode
manufactured on -Site from anthracite and coal tar pitch. Carbon -based anodes, also manufactured on -
site, were lowered into the cryolite solution and an electric current was applied. Spent potliner (SPL)
was periodically jackhammered out of the pots before reusing the steel pot casing. The first cut of the
SPL consists of the carbon cathode lining and is designated as code 'K088' by the United States
Environmental Protection Agency (USEPA). Fluoride and cyanide, the primary constituents of interest
(COls) in soil and groundwater, are associated with past production and K088 disposal practices. The
second cut of the SPL includes the steel shell, insulating brick, and metallic aluminum and is excluded
from the K088 designation.
Regulatory Background — National Pollutant Discharge Elimination System
Surface water discharges from the Facility are regulated through the NPDES program. Eleven outfalls are
permitted to discharge to either Badin Lake or an unnamed tributary to Little Mountain Creek. The
location of the outfalls and associated storm sewer piping are shown on Figure 2-2. While all locations
are permitted for stormwater discharges associated with an industrial activity, Outfalls 005, 011, 012,
013, and 019 are also permitted for non -process wastewater associated with groundwater infiltration.
Priority pollutant sampling is conducted at outfalls under NPDES permit NC0004308, and is discussed in
the context of Outfall 005, where periodic exceedances of the fluoride discharge limit occur (Section 8).
To address the issues, Badin Business Park applied to the North Carolina Division of Water Resources for
a special order by consent on July 2, 2018. The special order by consent specified the need to design and
construct an upgraded stormwater piping system in an effort to meet discharge limits stipulated under
the NPDES permit. Construction of the shallow stormwater system and complimentary efforts to identify
and mitigate the cause of the Outfall 005 fluoride exceedances are discussed in Section 8.

2.4 Regulatory Background — Resource Conservation and Recovery Act
In March 1990, Alcoa filed a Resource Conservation and Recovery Act (RCRA) Part B permit application
with the USEPA for the on -site storage of hazardous wastes (specifically K088) for greater than 90 days.
The permit application triggered a RCRA Facility Assessment (RFA) that was performed by USEPA Region
IV (A.T. Kearny Inc, 1990), and identified 34 solid waste management units (SWMUs) and 2 areas of
concern (AOCs). Corrective actions to be conducted were outlined in Alcoa's RCRA Part B permit, which
EHS Support LLC

Hydrogeological Conceptual Site Model Update — Badin Business Park
Background
was issued by what is currently the North Carolina Department of Environmental Quality (NCDEQ) in
cooperation with USEPA Region IV in March 1992.
The first step in the corrective action process was confirmation sampling at 7 SWMUs to verify if a
release had occurred. Alcoa identified 12 additional SWMUs after completing the RFA and voluntarily
completed interim measures at several SWMUs. Based on the outcome of these activities, Alcoa
completed a RCRA Facility Investigation (RFI) report (MFG Inc, 2001). The RFI findings immediately
supported a No Further Action status by the North Carolina Department of Environment and Natural
Resources (NCDENR) for 22 of the Facility SWMUs and AOCs. A No Further Action status was granted to
5 additional SWMUs following confirmatory sampling, while 18 units were to be further investigated
under the RFI process. Interim measures and remedial actions conducted to date have led to a No
Further Action or No Further Investigation status assigned to all or a portion of 43 SWMUs.
The RFI identified groundwater in three areas of the Facility needing further actions — the ABL (SWMU
2), the OBL (SWMU 3), and groundwater in the northern portion of the former Main Plant (Figure 1-1)
(MFG Inc, 2001). Between 2009 and 2013, Alcoa completed a Corrective Measures Study (CMS) to
update the Geologic Conceptual Site Model (CSM) and the HCSM, as well as to establish the remedial
action objectives. The CMS was completed in five phases that are documented in four reports
(Environeering, 2010, 2012a, 2012b, 2013).
The CMS (Environeering, 2010, 2012a, 2012b, 2013) documented that cover system upgrades have
resulted in beneficial effects to groundwater concentrations at the OBL. The earlier RFI results
demonstrated that there are no COls in soils adjacent to the OBL and only cyanide exceeded
groundwater screening values, whereas fluoride was not detected above North Carolina groundwater
criteria (i.e., Title 15A of the North Carolina Administrative Code [NCAC] Subchapter 2L standards or NC
2L standards) in groundwater samples collected from any OBL wells during the CMS Phase 3 engineering
data collection work (Environeering, 2012b). Available cyanide was detected above NC 2L standards in a
sample from one OBL well during the CMS Phase 3 engineering data collection; in subsequent sampling
events it was not detected above the NC 2L standards.
The CMS (Environeering, 2010, 2012a, 2012b, 2013) documented that COls in former Main Plant soils
were addressed by interim measure work and soil removal activities. Available cyanide, fluoride, and
trichloroethane were detected above NC 2L standards in the former Main Plant groundwater. Arsenic
was eliminated from Facility COI list due to high natural background concentrations in the area, and the
only other groundwater COI identified during the earlier RFI work was below NC 2L standards during the
CMS work. As part of the January 23, 2017, correspondence concerning the review of Phases 4 and 5 of
the CMS (NCDEQ, 2017), NCDEQ requested additional groundwater sampling for trichloroethene (TCE)
from newly installed monitoring well MW-110. To address the objective, groundwater samples were
collected from four monitoring wells (MW-4, MW-9, MW-16, and MW-110) (Environeering, 2018a).
Sampling results for all four wells were above NC 2L groundwater standard of 0.003 milligrams per liter
(mg/L). However, concentrations of TCE in the three wells sampled during the CMS had decreased,
indicating that the constituent plume is not expanding. Also, TCE results for MW-110 were only slightly
above the NC 2L groundwater standard at a concentration of 0.0065 mg/L.
At the ABL, the RFI documented that no COls were present in soil above conservative risk -based
screening levels, and only total cyanide exceeded screening levels in groundwater from a single well
downgradient of the landfill. The CMS work (Environeering, 2010, 2012a, 2012b, 2013) documented the
EHS Support LLC 7

Hydrogeological Conceptual Site Model Update — Badin Business Park
Background
beneficial effects of ABL cover system upgrades; available cyanide and fluoride were below NC 2L
standards in all sentinel groundwater monitoring wells.
As part of the January 23, 2017 correspondence concerning the review of Phases 4 and 5 of the CMS
(NCDEQ, 2017), NCDEQ requested an additional investigation at the ABL. A work plan was prepared that
outlined four tasks to address the requested items. The work plan was submitted in revised form on
April 2, 2018 (Environeering, 2018b), following conditional approval of the approach on January 31,
2018. The several reports detailing the outcome of the investigative activities are summarized in a letter
provided to NCDEQ dated December 22, 2021.
The four tasks outlined in the 2018 work plan are as follows:
• Conduct a surface water assessment involving sample collection from Little Mountain Creek and
the eastern drainage ditch on the Little Mountain Creek floodplain to assess concentrations of
polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) in sediment, and
PCBs, PAHs, fluoride, and cyanide in surface water. These results are discussed in Section 7.2.
• Evaluate the hydrological conditions to determine contributions of groundwater to the eastern
drainage ditch and the efficacy of the groundwater collection trench system. The results of this
evaluation are discussed in Section 7.2.
• Establish a geophysical baseline to delineate the linear extent of elevated constituent levels in
the wetland downgradient of the ABL and monitor the effectiveness of the groundwater
collection system. The results are described in Section 9.3.
• Determine the jurisdictional status of three drainage ditches (eastern, middle, and western) to
classify conditions at the base of the ABL. Results are documented in a notification of
Jurisdictional Determination (U.S. Army Corps of Engineers, 2020).
As detailed in Section 2.5.2, groundwater seeps that developed following cover improvements at the
ABL were managed with a slurry wall and trench system that intercepts and captures groundwater and
conveys it to a public treatment system. Subsequent upgrades to the downgradient seep management
system following the CMS starting in 2016 continue to show improvements to groundwater quality on
the floodplain of Little Mountain Creek (Section 9).
2.5 Previous Investigations and Remedial Activities
As stated in Section 2.4, the RFI identified groundwater in three areas of the Facility that need further
action: the ABL (SWMU 2), the OBL (SWMU No. 3), and groundwater in the northern portion of the
former Main Plant (MFG, 2001). Investigations and remedial actions to address the RFI findings were

2.5.1 Former Main Plant
The 123-acre former Main Plant encompasses several of the SWMUs that were defined in the RFI (MFG
Inc, 2001). Alcoa has conducted interim measure works and soil removal activities for soil at several

SWMUs and AOCs in the former Main Plant, which has resulted in No Further Action required to address
soil direct contact pathways.
Alcoa conducted a Facility -wide investigation to characterize fluoride and total cyanide in groundwater
in 2005 and 2006, which involved installing several new monitoring wells. Groundwater in the former
Main Plant was retained in the corrective action process as a result of the RFI and subsequent
groundwater investigations. Additional Facility -wide groundwater data were collected during the data
collection phase of the CMS in 2011 (Environeering, 2012a, 2012b). Based on the data collected during
groundwater investigations, fluoride and cyanide are identified as the primary COls in groundwater.
Areas with the highest groundwater fluoride and cyanide concentrations are near the On -Site Landfill
(SWMU 1) and the West Fill Area (SWMU 46; formerly known as the Coke Management Area). TCE is
also identified in the northern portion of the former Main Plant at MW-4, MW-9, MW-16, and MW-110.
Following a 2018 groundwater sampling event focused on these four wells, it was concluded that TCE is
decreasing in concentration and attenuating due to infiltration of lake water into the groundwater
system near MW-110 (Environeering, 2018a).
The On -Site Landfill is in the northeastern part of the former Main Plant. Prior to construction of the
former Main Plant, the ground surface slope decreased to the east toward Badin Lake. The landfill was
established in a natural ravine. The On -Site Landfill is a former SPL landfill with fluoride and cyanide as
the primary COls. The On -Site Landfill operated from the 1930s to the mid-1970s. Fill material mainly
consists of SPL and other carbonaceous material, metal debris, and silty sand (Geraghty & Miller, 1995).
Surface water control improvements were completed in 1996 (Alcoa, 1996), and a minimum of 2-foot
thick low permeability soil cover was placed over the unit (MFG, 2011).
The West Fill Area is situated at approximately 555 to 560 ft NAVD88 on a hillside west of the area
excavated for construction of the former Main Plant. It is located to the west of the former rail trestle
and coke storage area. There is a sharp elevation decrease eastward toward the former Main Plant and
Badin Lake and an increase in elevation westward toward the residential areas. A review of historical
topographic maps, historical photographs, aerial imagery, and recent Facility investigative activities
confirms that SWMU 46 is a fill area. This data supports that native fill soils and minor amounts of plant
process remnants were used to raise the area by approximately 10 to 20 feet to its existing grade
(Environeering, 2012a).
2.5.2 Alcoa Badin Landfill — SWMU 2
The ABL is located approximately 500 feet south of the fenced Former Main Plant and occupies
approximately 14 acres (Figure 2-1). The ABL decreases in elevation towards the southwest, south, and
southeast in the direction of Little Mountain Creek. Ajurisdictional wetland is located on the Little
Mountain Creek floodplain between the toe of the landfill and Little Mountain Creek.
The ABL was used by Alcoa and the community in Stanly County as a local "dump" for general municipal
refuse and industrial debris for approximately 70 years. The ABL was established in a natural ravine,
which extended from south of Wood Street towards Little Mountain Creek. Landfill operations ceased in
1979. Waste materials believed to be deposited in the landfill include solid refuse, construction debris,
process wastes, and municipal waste from the town and individuals. Excavated cut soils, excess spoils,
and weathered rock from grading in the early-1960s modernization of the Facility were also placed in
the ABL. The ABL was rough graded in 1980 using available on -site soils and was seeded with grass.
EHS Support LLC

Hydrogeological Conceptual Site Model Update — Badin Business Park
Background
In October 1997, the ABL surface was regraded to control run-off by regrading to a slope suitable for
mowing and installing a cover system consisting of 12 inches of silty clay soil, compacted to 95 percent,
overlain by a 6-inch vegetative layer consisting of silty clay soil combined with lime and fertilizer. Run-on
from high areas was managed by installing both lined and unlined ditches along the flanks of the ABL
that discharge to the flood plain of Little Mountain Creek. Channels were lined with a 4-inch-thick
concrete revetment mat orjut mat and grass. The channels were designed to accommodate 25-year
storm events (Alcoa, 1998). Three seeps were identified at the toe of the ABL following the completion
of these activities.
In June 2000, the construction of a low -flow seep collection system was completed for combining the
three seeps into a single discharge under the Facility's NPDES permit. In 2005, the discharge was
eliminated through the installation of a forced main to route the seep water to a utility sewer that leads
to Stanly County Utilities' publicly owned treatment works (POTW).
In 2016, the existing seep collection system was upgraded to improve overall seep capture and
collection efficiency. The previous system collected water from three small seeps in ground surface
collection basins. The basins were prone to flooding and surface water infiltration. This caused clean
surface water to be captured, pumped, and treated. The new system was intended to intercept water in
a below -grade collection trench immediately downgradient of the ABL. In addition, a slurry wall was
installed downgradient of the collection trench. The slurry wall was installed to offer two benefits: (1) a
barrier against ABL groundwater migrating towards the floodplain, and (2) to provide a barrier so clean
groundwater from the floodplain would not flow into the collection trench (Power Engineers Inc, 2017).
Following installation of the trench and barrier wall, seeps developed upgradient of the collection
trench. In 2017 and 2019, modifications were made to the trench system to collect seeps that developed
on the hillside upgradient of the 2016 collection system. The area is currently monitored annually using
geophysical surveys to confirm the efficacy of the remedial measure. The efficacy of the ABL collection
trench is discussed further in Section 9.
2.5.3 Old Brick Landfill — SWMU 3
The OBL is an approximately 3-acre, unlined landfill located approximately 0.75 miles northeast of the
former production Facility on a slope bordered by Badin Lake. Materials including used baking furnace
bricks were disposed of in the OBL from 1915 to 1960. Closure of the landfill consisted of covering the
area with 12 inches of compacted clay, stabilizing the cap with vegetative cover, and diverting
stormwater with drainage ditches (Aquaterra, 1991b).
The 2001 RFI report (MFG Inc, 2001) demonstrated that there were no COls present in soils adjacent to
the OBL at concentrations exceeding the conservative risk -based screening values. As a result, soils do
not present a risk. The RFI results did show that groundwater in a few wells contained total cyanide that
exceeded the screening values. The unit was retained in the corrective action process because of the
detection of total cyanide in selected groundwater wells above the regulatory standard. Alcoa upgraded
the OBL cover system in 2006 to eliminate point source discharges to surface water under the Facility's
NPDES permit. This upgrade consisted of cover system reconfiguration to mitigate surface water
infiltration, control stormwater flow, and manage stormwater run-off through infiltration or controlled
discharge under the NPDES permit (Environeering, 2012a).

3 Investigation Activities in 2022
Investigation activities completed in 2022 were designed to support the development of a refined
understanding of hydrogeological controls on groundwater flow directions and constituent transport at
the former Main Plant and ABL. Hydrogeological properties of various geologic units present at the
Facility were characterized using the following lines of evidence:
• Visual observations of geologic and hydrogeologic properties through observations of drill cores
and excavated test pits.
• Laboratory characterization of soil physical properties to identify hydrogeologic properties of
distinct native soil units, and remolded native soil units as a proxy for fill derived from native
soils.
• Hydraulic data collection (step drawdown tests) to confirm monitoring wells adequately capture
the most conductive units and to qualitatively assess hydraulic properties of weathered rock
units.
• Measurement of groundwater heads in wells discretely screened across PWR or fractured rock
to capture the most conductive intervals to refine potentiometric maps and assess groundwater
flow directions.
Figure 3-1 illustrates the locations where:
• Soil borings, piezometers, and monitoring wells were installed in 2022.
• Soil physical property samples were collected in 2022.
• Aquifer testing (step drawdown pump tests) was conducted in 2022.
Lithologic data was obtained by drilling 21 monitoring wells (MW200 through MW220), 1 piezometer
(PZ18RD), and 6 soil borings (13300 through B305) (Figure 3-1). Soil borings and monitoring wells were
drilled and installed by SAEDACCO, Inc. of Fort Mill, South Carolina. Initial wells and soil borings were
drilled using the sonic technique to obtain continuous soil and rock cores (MW220, B300 through B305)
for initial characterization of the soil profiles. In the interest of minimizing time in the field, subsequent
monitoring wells were installed using a hollow stem auger and continuous split spoon samples were
collected across the saprolite/weathered rock interface. Air rotary drilling was used at locations where
more competent material precluded the collection of split spoon samples.
Wells and the piezometer were constructed with 2-inch inner diameter polyvinyl chloride (PVC) screens
with 0.01-inch slotted PVC screens. Screens were targeted in PWR (or fractured rock where PWR was
absent or dry) with short lengths (5 to 10 feet) to avoid screening across overlying soil units. Wells were
developed by surging with a surge block followed by purging with a submersible pump. Boring logs for
the newly installed monitoring wells that include detailed well construction information are provided in
Attachment A. Wells were surveyed by a North Carolina licensed Professional Land Surveyor; survey
data and well construction details are provided in Attachment B.

Soil characterization samples were obtained from seven drilling locations. Samples were collected in
Shelby tubes to be representative of in situ conditions. Samples were also collected in bags and
reconstituted in the lab as an indicator of the hydraulic properties of fill composed of native soils.
Samples were submitted to integrated Testing Laboratories of Houston, Texas for the following soil
physical parameter analysis:
• Effective porosity package (moisture content [ASTM D2216], bulk density [American Petroleum
Institute {API) RP40], total and effective porosity [ASTM D425]).
• Hydraulic conductivity package (hydraulic conductivity and effective permeability to water [API

Aquifer testing was completed in nine wells screened across PWR or fractured rock using the step-
drawdown method. The method involved inserting a Monsoon° pump and Levellogger° pressure
transducer into the test well and the water level was allowed to equilibrate. Pumping was initiated and
the rate was increased in steps and terminated after approximately 1 hour or when the well ran dry.
Pumping rates were determined based on the water level response of the particular location and ranged
from 200 to 7,300 milliliters per minute (mL/min). Data was recorded in 5-second intervals using the
pressure transducers and converted to a depth to water. Hydraulic conductivity was then calculated
from the pumping rate and transducer data using Aqtesolv° software. Detailed aquifer testing
calculation results and software output are provided in Attachment D and summarized in Table 3-2.

Depth to groundwater measurements were completed on September 9, 2022, and October 19, 2022, in
newly installed monitoring wells and existing wells screened across PWR or fractured rock. Depth to
water measurements were gauged from the top of casing with an electronic resistivity probe, which
measured the water depth with a precision of ± 0.01 foot. The measuring device was cleaned prior to
use in each well. Water levels were captured prior to any subsequent disturbance to the well. The water
levels in the wells were made consecutively in the shortest period (less than one day). Results are
discussed in Section 6.5. Groundwater elevation measurements are provided in Attachment E.
Two test pits were excavated, and groundwater samples were collected from wells and borings
upgradient of the West Fill Area (SWMU 46) to better understand groundwater hydrology and
contaminant fate and transport in this area. Test pit locations and the West Fill Area are shown on
Figure 3-1. Test pits were dug to qualitatively observe the location and magnitude of groundwater flow
over a subsurface profile in the upslope and flat area of the former Main Plant. Test pits were secured
and left open for approximately 24 hours to observe if and how much groundwater accumulated.
Residual soil/saprolite intervals of the test pits were dry and minor groundwater seepage was observed
along fractures in the PWR interval. Observations from the test pits are used to support the Site
hydrogeologic conceptualization as described in Section 6.
Samples were collected under chain of custody protocol from borings 13300, 13301, 13302, 13303, 13304,
13305, MW218, and MW219 and analyzed using USEPA-approved methods for fluoride (Method 300.0),
total cyanide (Method D7511-12), and available and free cyanide (Method OIA-1677). Samples were
collected using a portable (non -dedicated) bladder pump using low -flow purging and sampling
procedures. Reusable equipment used to collect groundwater samples was decontaminated before use
at another well. Dedicated air supply and water discharge tubing lines were used at each well to reduce
the level of decontamination required between wells. Each well was purged at a relatively low rate to
reduce drawdown. The purge water was field-tested for pH, turbidity, specific conductance, oxidation-
reduction potential (ORP), and temperature. Wells were purged according to low flow sampling criteria
(Puls and Barcelona, 1996). Samples were collected directly into laboratory -prepared bottles, labeled,
and placed on ice in sealed coolers for delivery to a North Carolina -certified laboratory for analysis. All

4.1 Regional Geology
The Facility is located in the Piedmont physiographic province of the Appalachian Highlands
physiographic region (Fenneman, 1917). The Piedmont physiographic province is characterized by
dominant ridgelines that follow the strike of resistant lithologies, valleys perpendicular to ridgelines that
follow regional fault structures, and many small hills cut by streams flowing in a dendritic pattern.
Streams are associated with flat -lying alluvial deposits (alluvium) at the base of valleys. Overall, the
ground surface has relatively low relief due to heavy weathering of the underlying rocks. The intense
weathering promotes the collapse of hillsides resulting in localized colluvium deposits. Rocks underlying
the eastern half of the Piedmont (where the Facility is located) belong to the Carolina Slate Belt (Figure
4-1).

Figure 4-1 Regional Geographical and Geological Overview
Rocks of the Carolina Slate Belt were deposited through a combination of sedimentary processes and
fallout from volcanic eruptions (North Carolina Geological Survey, 1985). Sediments that lithified to form
Slate Belt rocks were originally deposited beneath water, likely in a submarine setting (Feiss, 1982). The
North Carolina Geological Survey (1985) describes Carolina Slate Belt rocks in the former Main Plant and
ABL areas as Cambrian age metamudstone and meta-argillite interbedded with metamorphosed
sandstone, conglomerate, and metavolcanic rocks of the Cid Formation. Regionally, the mudstone
grades upward into shale (Stromquist and Sundelius, 1969). The lithologic variation has produced
northeast -southwest trending ridgelines and valleys that follow the strike of bedding. Carolina Slate Belt
rocks in the region are mildly metamorphosed and deformed, leading to northeast -southwest fold hinge
axes in the Facility vicinity that are intersected by perpendicular faults. The orientations of bedding/fold
hinges and the perpendicular fractures broadly dictate the crisscross pattern of river drainages in the
area. The orientation of Little Mountain Creek aligns with perpendicular fractures, whereas the
perpendicular tributaries follow the strike of bedding and fold hinges.
At the OBL east of the former Main Plant, the Cid Formation consists of mafic metavolcanic rocks
composed of dark green to black basalt flows and basaltic tuffs interbedded with intermediate volcanic
rock and metamudstone. In this location east of the former Main Plant, drainages follow a dendritic

Regional Setting
Rocks of the Piedmont are heavily weathered at the ground surface due to a combination of high rainfall
and the humid and warm climate. As a result of the climate, the thickness of the rock weathering profile
in the Piedmont can range anywhere between 1 and 25 meters, although weathering is typically thinner
on ridgetops and slopes (Buol and Weed, 1991; Sowers and Richardson, 1983). The subsurface profile is
characterized by a gradual transition from soil through decomposed to unweathered rock with
increasing depth. The boundaries between different weathering zones are not well defined and the
transitions are gradual. The thickness of the zones may also be highly variable over small spatial extents
(e.g., up to 20 meters over an area the size of a city block; Sowers and Richardson, 1983). A generalized
soil profile overlying metasedimentary rocks in the Piedmont Physiographic province is shown on Figure

Figure 4-3 Generalized Weathering Profile and Nomenclature of Foliated Metasedimentary Rocks
from the Piedmont Physiographic Province
Unweathered rock is present beneath the weathering zone, and typically has minimal to no staining on
fractures and joints, and mica and feldspar are unaltered (Pavich et al., 1989). A zone of PWR exists
above the unweathered rock and is characterized by soft to hard rock where joints and fractures are
typically stained, and primary rock minerals are altered in part.
PWR grades upward into a zone of residual soils. In general, residual soils are derived in place from the
chemical decomposition (weathering) of primary minerals in the underlying PWR and bedrock. If
weathering results in small volume changes and the original fabric and most original rock defects are
retained, soils are called 'saprolites' (Sowers and Richardson, 1983). When the weathering is
accompanied by large volume changes and little or none of the original rock fabric remains, residual soils

Figure 4-5 Typical Rock Weathering Profile
The residual soil and saprolite are storage zones where groundwater is 'trapped' due to the high relative
porosity values (typically between 35 and 55 percent) and low relative permeability (Figure 4-5).
Precipitation infiltrates soil until it reaches the saturated zone, where it is stored in pore spaces.
Groundwater in the storage zone seeps from residual soil or saprolite into the PWR, where the porosity
is lower but the relative permeability is substantially higher. It is within the PWR that groundwater
primarily discharges and flows (LeGrand, 1967).
The water table elevations in the Piedmont soils generally follow the ground surface and can vary by
several feet in response to precipitation events (LeGrand, 1967 and 2004; Buol and Weed, 1990; Sowers
and Richardson, 1983; Daniel and Dahlen, 2002; Swain et al 2004; McVay et al., 2004). However, the
presence of structures and fractures in PWR and unweathered rock can influence groundwater flow
directions. Groundwater flow is typically 10 times greater parallel to planar structures in PWR than
perpendicular to it (Sowers and Richardson, 1983). In the rock, groundwater is contained entirely in
fractures, and groundwater elevations can vary over a few feet depending upon the localized
interconnectivity of fractures (Sowers and Richardson, 1983).

Geology and hydrogeology at the Facility differ from the regional framework due to the extensive
engineered cut and fill activities that took place during Facility construction and redevelopment
activities throughout the 1900s. The magnitude of change is visualized in Figure 5-1, which shows the

Figure 5-1 Conceptual Effect of Facility Development on the Groundwater Flow System
Before filling Badin Lake and excavating areas of native soils, groundwater flow likely followed a typical,
topographically -driven Piedmont groundwater flow system with a topographic divide across the area
that would become the former Main Plant (Figure 5-1). Groundwater in the southern portion of the
former Main Plant flowed toward the southeast and ultimately discharged to the Little Mountain Creek
floodplain. Groundwater in the northern portion of the former Main Plant would have likely flowed east
and northeast to the former valley that became Badin Lake.
Filling Badin Lake and excavation and fill for development of the Facility modified the natural
groundwater flow system. Badin Lake is not a natural feature; it is a man-made feature that was filled
against a steep -sided valley wall of exposed and permeable PWR. PWR is observed outcropping along
the lake shore (Figure 5-2) and was also documented on the lake bottom when the lake was lowered for
the Badin Lake sediment capping project (photo 96 of Power Engineers Inc., 2013). Extensive excavation
removed residual soils over a substantial portion of the former Main Plant leaving only PWR and rock
and introduced native soils and production wastes to valleys in other areas of the Facility. This
engineering work conducted over the 1900s modified the geological controls on groundwater flow
directions.

Figure 5-2 December 2021 Photo of PWR Outcropping Along the Shore of Badin Lake Adjacent to
the Former Main Plant
As illustrated conceptually on Figure 5-1 and documented in the following sections, groundwater is now
recharged both by Badin Lake from the east and from higher elevations west of the former Main Plant
and ABL. Recharge to groundwater from Badin Lake occurs through a direct connection to permeable
PWR, and groundwater flows from the northeast to southwest through PWR and rock along regional
structures to ultimately discharge on the floodplain of Little Mountain Creek.
5.1 Areas of Engineered Cut and Fi
To demonstrate the magnitude of topography changes and identify where the location of PWR and
infrastructure within PWR affects groundwater flow directions, the modern ground elevation was
compared to elevation data from a survey conducted in 1913 prior to development of the Facility

Figure 5-3 was developed by digitizing elevation contours measured in 1913 before plant development
and subtracting the modern (2003) elevation obtained from public 1/9 arc -second digital elevation data
obtained from the USGS. The Alcoa elevation datum used on the 1913 map was corrected by subtracting
31.48 feet to match the NAVD88 datum. Where historical contours did not extend, fill thickness was
taken from Facility boring logs that fully penetrated the fill. The result is shown on Figure 5-3; the

In areas where valleys were filled (e.g., ABL, West Fill Area, On -Site Landfill), material was placed upon
the existing saprolite and residual soil where it was present. Locations where residual soil and saprolite
are believed to be thin or absent beneath fill are only very localized portions of drainages that occupied
the bottom of subsequently filled ravines. Geophysical surveys presented in the 2001 RFI (MFG Inc,
2001) and CMS Phase 3 (Environeering, 2012b) reports indicate that fill is heterogenous; there are
localized areas where fill contains industrial materials interlayered with reworked native soils. Other
areas likely consist of native soils that were excavated and used as fill during Facility development and
construction.
In areas where material was excavated, residual soil and saprolite were entirely removed from
underlying PWR and rock in some areas and replaced by a thin veneer of fill. Figure 5-4 was developed
from Facility boring logs and shows the cross section that runs from Badin Lake to Little Mountain Creek,
the relationship of fill to residual soils in former valleys, and how soil was removed from PWR and rock
in places.

Residual soils and saprolite were removed from the underlying PWR and fractured rock over a large
portion of the former Main Plant in this area. Where residual soil and saprolite were largely removed
and replaced with a thin veneer of fill, precipitation can infiltrate directly into PWR or rock and the
dominant control on the groundwater flow direction is geologic structures within these units. Based on
strike and dip measurements of bedding in rock and PWR outcrops measured with a Brunton compass
during field efforts in 2022 (Figure 5-6), the strike of bedding and predominant geologic structures at the
former Main Plant trends between Badin Lake and the flood plain of Little Mountain Creek. Note, the
strike and dip features measured in 2022 align with the strike of regional geologic structures indicated
on Figure 4-2.

5.3 Areas of Fill
As indicated on Figure 5-3, areas of fill are present at the north end of the plant, where they were used
to fill in an eastward trending natural ravine. This valley is referred to as the "Northwest Valley" in other
facility documents and includes two identified SWMUs —the On -Site Landfill (SWMU-1) and the Pine
Tree Grove (SWMU 44). A second eastward trending ravine was present to the south and is now
occupied by the West Fill Area. The ABL was developed over a bifurcated natural ravine that trended
south to southwestward toward Little Mountain Creek. Materials used to fill the ravines included both
natural soils and anthropogenic materials (Environeering, 2012b).
At the Pine Tree Grove area, the valley terminated at an embayment in Badin Lake that was filled at
some time in the mid- to late-1900s. Fill materials consist of decaying organic material, mulch, and wood
debris; sand, silt, and clay soils; construction debris including gravel, concrete, brick, and rock fragments;
aluminum scrap; and granular carbonaceous material. Primarily clayey silt residual soils and saprolite are
present beneath fill materials. PWR is present beneath the residual soils (Environeering, 2012b).
In the West Fill Area, fill materials consist primarily of sand, silt, and clay soils with minor lenses of
granular carbonaceous material. Residual soils and saprolite are present beneath fill materials and are
mainly clayey -silt with subordinate sandy silt/silty sand. Saprolite and residual soils are thin and less
than 1 foot thick near the center of this historical valley and are underlain by PWR (Environeering,
2012b).
Fill at the ABL is described as concrete slabs, brick and concrete fragments, bottles, black cinders, nails,
rope, aluminum sheeting, plastic sheeting, organic and wood fragments, coal, rubber, and metal pieces.
A substantial amount of natural materials and construction debris were placed in the ABL following
plant development activities.
As indicated on Figure 5-3, areas of fill are spatially discrete and further modified by remediation
activities (e.g., capping and drainage modifications to the On -Site Landfill and ABL; Section 2.5). The only
continuous unit at the Facility is the PWR-fractured rock system, and the hydraulic properties and
characteristics of the PWR-fractured rock system control groundwater fate and transport across the
former Main Plant and ABL.

This section summarizes the primary controls on hydrogeology at the Facility, with supporting
information provided in Section 6.1 through Section 6.5. The primary controls for hydrogeology at the
Facility are the location of groundwater recharge on the slope to the west of the Facility, from Badin
Lake east of the Facility, and the location of permeable units and associated structures that direct
groundwater flow. The location of infrastructure and the relationship to permeable units also places an
important control on groundwater flow directions. The primary permeable units at the Facility are PWR
and fractured rock. The importance of groundwater flow in the PWR is evident from observations of the
test pit completed near boring B300 in 2022. A test pit was excavated through residual soil and saprolite
to intercept the PWR. Observations of the test pit walls indicate seepage along PWR and rock fractures,
whereas the residual soil and saprolite were observed to be dry (Figure 6-1).

6.1 Monitoring Well and Piezometer Network
In March 2020, Alcoa performed an assessment of the monitoring well network. Of the 113 wells and
piezometers documented at the Badin Business Park and outlying SWMUs, 106 are believed to be
present. This does not include the 21 monitoring wells and 1 piezometer installed in 2022. The following
details the 7 wells that are believed to be inoperable.
Badin Business Park wells BF-3, BF 4, BF-7, and B016-MW-1 through B016-MW-3 were located in areas
impacted by 2012 demolition activities and are assumed to be destroyed. Well MW-26 was located in an
area south of the Pine Tree Grove Area and is believed to have been affected by soil placement activities
and is no longer accessible.

Wells have been installed by different contractors over the years, and lithology descriptions differ. Wells
are generally screened across the following lithologies (Environeering, 2012b):
• Soil units, including residual soil or saprolite (not always distinguished from each other)
• PWR described as hard weathered rock (HWR) or soft weathered rock (SWR)
• Fractured rock that is relatively unweathered
The focus of the present study is the monitoring wells listed in Attachment E that are screened in PWR
and/or fractured rock, or with screens or sand packs that partially span low permeability saprolite and
are mostly screened in PWR.
6.2 Hydraulic Conductivity
Hydraulic conductivity values calculated from slug or pumping tests in Facility monitoring wells have
been provided in several historical reports. Historical hydraulic conductivity for bedrock (including
pump test data from the present study) is provided in Table 6-1. Note, all values in Table 6-1 were
converted to centimeters per second (cm/sec) for consistency.

Hydraulic conductivity data for wells at the former Main Plant and ABL have been collected from wells
screened exclusively in rock or PWR, and wells exclusively screened in fill materials. Hydraulic
conductivity data exists for several other wells; however, these wells are screened across multiple units
and the values are not representative of native soils. Notably, no hydraulic conductivity data is available
for wells screened exclusively in native soil, except for the following wells:
• ABL-MW-2 was drilled using an air rotary drill and logged from the air rotary cuttings. There is
uncertainty in contacts between units due to the drilling method.
• PZ-5 through PZ-11 are reportedly screened in saprolite, and hydraulic conductivity values from
slug tests are provided in the RFI report (MFG Inc, 2001). Logs for these piezometers are not
available to verify that the lithology intercepted by the screen and filter packs is exclusively
saprolite.
Since the hydraulic conductivity data for ABL-MW-2 and PZ-5 through PZ-11 are not reliable indicators of
the hydraulic properties of native soils, the corresponding hydraulic conductivity values are not included
in Table 6-1.
No Facility monitoring wells are definitively and exclusively screened in residual soil or saprolite at the
Facility, most likely because the units did not yield sufficient groundwater during drilling. To address the
data gap pertaining to the hydraulic properties of residual soil and saprolite, samples were collected in
2022 and submitted for laboratory testing of hydraulic properties (Section 3). Both in situ samples and
reconstituted samples were measured for hydraulic properties to estimate the hydraulic properties of in
situ native soils and soils reworked and used as fill material. The results indicate overall low vertical
hydraulic conductivity values for these units of 1.58 x 10-Ito 3.38 x 10' cm/sec (Table 3-1).
In contrast to native soils, hydraulic conductivity values of wells screened over fill containing industrial
materials are substantially higher (geometric mean of 1.27 x 10-3 cm/sec; Table 6-1). However, as
described in Section 5.3, areas of fill are spatially discrete and do not form a continuous water -bearing
unit. Furthermore, the hydraulic properties are highly heterogenous with localized, higher hydraulic
conductivity areas defined by SWMUs where industrial materials are present and low hydraulic
conductivity areas where native soils were used to fill topography during plant construction. Vertical
(and lateral) groundwater flow into and out of areas of fill containing industrial materials is limited by
low permeability saprolite and residual soils that were present prior to placement of fill. It is only in
limited and discrete areas, where saprolite or residual soil was eroded or excavated prior to placement
of fill, that there is significant communication between anthropogenic fill and PWR or fractured rock.
Unlike fill materials, PWR and fractured rock occur over the entire former Main Plant and ABL areas. As
indicated in Table 6-1, the PWR/fractured rock groundwater system has modest hydraulic conductivity
(geometric mean of 1.25 x 10' cm/sec). The values obtained from PWR wells installed across the
Facility in 2022 using step draw -down tests are a similar order of magnitude to those previously
obtained from Facility PWR wells via slug tests and indicate the PWR has similar hydraulic properties
across the former Main Plant and ABL. Because of the broad extent and consistent hydraulic
conductivity values, PWR is the primary unit through which groundwater moves and controls COI fate
and transport at the Facility.
As described in previous studies, the combination of weathered bedrock and fractures in unweathered
bedrock creates intervals of high hydraulic conductivity. The importance of fractures for creating areas
EHS Support LLC 34

Hydrogeological Conceptual Site Model Update — Badin Business Park
Site Hydrogeology
of higher hydraulic conductivity is evidenced by the loss of fluid circulation during coring and drilling at
MW-20A (Geraghty & Miller Inc, 1995). The orientation of these fractures is an important factor that
controls groundwater flow directions.
Vertical Groundwater Gradients
Vertical groundwater gradients at the former Main Plant were studied during the 2001 RFI (MFG Inc,
2001) and are summarized below. Water -level data from paired wells with screens completed at
different elevations were historically evaluated. Wells that were evaluated included the MW-2/2A, MW-
6/6A, MW-20/20A, and MW-25/25A well pairs.
• The MW-2/2A and MW-20/20A well pairs are on the western side of the former Main Plant near
the On -Site Landfill, and a downward vertical groundwater potential from fill to PWR or
fractured rock was noted. These wells are located in and around the On -Site Landfill, and
downward groundwater migration is limited by the presence of pre-existing saprolite and/or
residual soils.
• The MW-6/6A and MW-25/25A well pairs are closer to Badin Lake, and an upward vertical
gradient was noted.
The upward vertical gradient at MW-6/6A and MW-25/25A indicates potential upward groundwater
movement from the PWR and fractured rock into the unconsolidated water table units in areas closer to
the lake. This is consistent with the conceptualization that Badin Lake provides recharge to PWR and
fractured rock along bedding planes exposed beneath the lake level. As indicated on the hydrographs in
Section 6.4, there are periodic and short-lived 'spikes' where there is a downward gradient from fill to
the PWR system in the vicinity of MW-27 and MW-17, likely associated with precipitation events that
soak into higher permeability areas of fill and rapidly dissipate into the PWR groundwater system.
Hydrographs for ABL piezometers were presented in the 2012 Phase 3 CMS following a two-year
transducer deployment (Environeering, 2012b); the data are reproduced in Figure 6-2.
• Transducer data show water levels at the PZ-1S, PZ-11, and PZ-11D cluster (upgradient edge of the
ABL) have consistently downward gradients.
• Near the center of ABL at the PZ-2S/PZ-2D cluster, there are apparent downward vertical
gradients. The magnitude of response in both wells is similar (note, the shallow well appears to
have dried up periodically), and both wells vary in concert.
• At the PZ-3 cluster on the floodplain of Little Mountain Creek, vertical groundwater gradients
are consistently upward.
These results are consistent with groundwater discharge from beneath the ABL and from the hillside to
the west to the floodplain of Little Mountain Creek. Groundwater discharge to the floodplain of Little
Mountain Creek is also supported by periodically flowing artesian conditions at monitoring well ABL-
MW-3, which is located on the western side of the floodplain.

Transducers were placed in wells screened over residual soil and PWR (MW-5 and MW-27), fill (MW-25),
or PWR (MW-16, MW-17, and MW-108). The locations of transducer wells are shown on Figure 6-3.

The transducer study indicated that the lake level was consistently higher than the groundwater
elevation in soil and fill wells MW-5 and MW-25 and was periodically higher than groundwater at MW-
27 (Figure 6-4). The lake level was consistently higher than the groundwater elevation in PWR wells
MW-16 and MW-108 and generally higher than groundwater at PWR well MW-17. At MW-17 and MW-
27, spikes in groundwater elevation above the lake level corresponded with spikes in lake level
elevation. These results indicate that large-scale precipitation events lead to localized recharge that
rapidly infiltrates downward and dissipates into the PWR groundwater system.
It was concluded that Badin Lake may act as a flow barrier to groundwater from the former Main Plant
(Environeering, 2012b). Consequently, groundwater may not discharge to the lake as depicted in the
groundwater contours provided in the RFI (MFG Inc, 2001) and the 2005/2006 Facility -wide
groundwater monitoring events (BHE Environmental Inc., 2005, 2006). However, it was noted in the
CMS Phase 3 that this hypothesis would require additional data collection and verification
(Environeering, 2012b).

6.5 2022 Groundwater Elevation Data
As described in the 2001 RFI (MFG Inc, 2001), flow within PWR and rock can be complex due to
preferential flow along fracture zones of relatively greater hydraulic conductivity. As a result, flow is not
necessarily perpendicular to the groundwater elevation equipotential lines. To better constrain
groundwater flow potential and directions in PWR and rock, additional PWR monitoring wells were
installed in 2022 to improve the spatial coverage of the well network for understanding interactions
between Badin Lake and groundwater.
Groundwater elevation data for PWR and rock wells was measured in 2022 (Section 3). The results are
tabulated in Attachment E. Groundwater elevations were measured at two different conditions on
September 8, 2022 and October 19, 2022 to assess temporal variability in groundwater flow directions
within the PWR unit. Groundwater elevations were compared to Badin Lake level data to develop
groundwater contours. The data for the following monitoring wells was collected during this time but
not used in contouring:
• MW-110, which is screened in residual soils
• MW-104 and MW-105, which are screened across unspecified soils and PWR
• MW-109, which has a long (25-foot) screen that likely short-circuits different rock fracture
intervals and is unrepresentative of the overall groundwater potentiometric head
Historical Badin Lake level data at Badin Narrows where the lake enters the Yadkin River is available
from the Cube Hydro websiteZ. On September 8, 2022, the lake level was 509.54 feet NAVD88. On
October 19, 2022, the lake level was 509.05 feet NAVD88.
Notably, the lake level remains relatively constant to maximize electricity generation; therefore, large
fluctuations in the lake level are not expected to affect groundwater -lake water interaction. Daily lake
elevations measured between October 2017 through October 2022 at Badin Narrows reported a narrow
range of elevation fluctuations between approximately 505.11 to 509.69 feet NAVD88 (excluding
obvious outliers, e.g., 537.88 feet NAVD88 on October 29, 2022, which would have entirely submerged
the former Main Plant and ABL).
Groundwater elevation contours for the 2022 monitoring events are provided on Figure 6-6 and Figure
6-7 for September 8, 2022, and October 19, 2022, respectively. The contours are overlain with vectors
that indicate the magnitude and direction of groundwater gradients. The results of both monitoring
events indicate that groundwater recharge from Badin Lake in the east and higher elevations in the west
converge in a narrow strip parallel to the lake shore. Note that preferential flow in PWR occurs along
fracture zones of relatively greater hydraulic conductivity, and as a result, flow is not necessarily
perpendicular to the groundwater elevation equipotential lines.
Based on the long-term transducer study shown on Figure 6-4 and Figure 6-5, recharge from Badin Lake
is expected to persist during wetter times. Changes to groundwater conditions will continue to be
assessed during wetter months and in different seasons during 2023 to verify that there is constant
recharge from Badin Lake.

The groundwater flow direction ultimately curves to flow from northeast to southwest and discharges
primarily to the flood plain of Little Mountain Creek. This result is consistent with the elevation of the
Little Mountain Creek floodplain (less than 470 feet NAVD88), which is almost 40 feet lower than the
typical level of Badin Lake, and along the alignment of regional geologic structures and subsurface
Facility infrastructure.
Seepage Velocity
Groundwater seepage velocity has previously been calculated at the ABL (Aquaterra Inc., 1991a), the
former Main Plant (Geraghty & Miller, 1995), and across both areas during the RFI. In these previous
estimates, various units were lumped together to arrive at Facility -wide seepage velocity values.
Following the updated hydrogeological conceptualization presented herein, whereby groundwater flow
is profoundly affected by the nature of specific units, seepage velocities were calculated for specific
units to better understand the controls on groundwater fate and transport. Seepage velocity is
calculated using the equation:
Ki
v=-
n
Where:
v = seepage velocity
K = hydraulic conductivity
i = the groundwater gradient
n = effective porosity
The seepage velocity result in cm/sec is converted to feet per day using standard conversion factors. The
parameters used in the calculations and the results are provided in Table 6-2.

Notes:
1. Effective porosity of native fill was taken from the average of remolded sample values, and saprolite and residual soil from
the average of in situ samples, given in Table 3-1. Effective porosity for PWR/Rock uses the value typical of siltstone
(Johnson, 1967). Effective porosity for anthropogenic fill follows reasoning from previous studies (Aquaterra Inc., 1991a).
2. The value for hydraulic conductivity of native fill was taken from the geometric mean of remolded sample values, and
saprolite and residual soil from the geometric mean of in situ samples, given in Table 3-1. Hydraulic conductivity values for
anthropogenic fill and PWR were obtained from Table 6-1.

3. Groundwater gradient was calculated from the groundwater elevations on Figure 6-6 (ABL-MW-6 to PZ-18RD at the ABL is
0.039 Feet per foot (ft/ft); MW-220 to MW-208 at former Main Plant is 0.006 ft/ft; MW-219 to MW-32 for western slope is
0.034 ft/ft).
4. Vertical hydraulic conductivity was measured on saprolite and residual soil; these values are assumed to equal horizontal
hydraulic conductivity.
5. Calculated velocities assume the same gradient across lithologic units, and this condition is expected to vary slightly.
Forthcoming groundwater elevation data will provide the necessary input for future revisions.
ABL = Alcoa Badin Landfill
cm/sec = centimeters per second
PWR = partially weathered rock
As indicated on Table 6-2, seepage velocities are two to three orders of magnitude lower for native fill,
saprolite, and residual soil compared to anthropogenic fill and PWR/Rock. Indeed, the PWR/Rock
estimate is likely biased low as effective porosity in fractured rocks can be as low as 1 percent
(Worthington, 2022), and use of a lower effective porosity value would increase the calculated seepage
velocity an order of magnitude. Seepage velocities are higher where the groundwater gradient is
steeper (ABL and slope west of the Main Plant).
These results support the conclusion that PWR is the primary conduit for groundwater flow at the
Facility, as it is extensively present and has high calculated seepage velocities compared to native soils
and fill derived from them. In contrast, anthropogenic fill has high seepage velocities but is present only
in discrete areas. Seepage into or out of anthropogenic fill is limited by the presence of underlying
saprolite and residual soils, and groundwater flow is controlled by areas where it is in direct contact with
PWR.

A combination of vertical groundwater gradients, groundwater flow primarily through PWR and
fractured rock, and geochemical attenuation appear to be the primary controls on plume geometry at
the former Main Plant. This section summarizes historical data on the distribution of the primary COls —
fluoride and available cyanide in groundwater at the former Main Plant and ABL — along with a
preliminary evaluation of geochemical controls on COI attenuation to support this HCSM document. A
full description of the current understanding of all COI distributions is provided in the CMS Phase 3
Report (Environeering Inc., 2012b), and is not reproduced here. Investigations following the CMS work
have focused on assessing COI distributions in discrete areas; TCE distributions in the northern area of
the former Main Plant (Environeering, 2018a); and PCB, PAH, fluoride, and cyanide distributions in
surface water and sediment downgradient of the ABL (Environeering, 2018c; Civil Environmental
Consultants [CEC], 2020).
Facility -wide groundwater sampling events were conducted at the ABL and former Main Plant during the
RFI in September and October 1999 (MFG Inc, 2001); at the former Main Plant in August 2011 (BHE
Environmental Inc., 2011) and June 2006 (BHE Environmental Inc., 2006); and during the CMS Phase 3 in
June 2011 (Environeering Inc., 2012b). Planning is currently underway for a Facility -wide groundwater
sampling event.
Based on the magnitude of remedial activities conducted at the Facility, it is anticipated that the current
groundwater concentrations will look significantly different to the historical data described below.
Nature and Extent of Groundwater Fluoride and Cyanide Impacts
Fluoride concentrations in groundwater at the ABL reported in the CMS Phase 3 report (Environeering
Inc., 2012b) identified total fluoride exceeding the NC 2L standard only in piezometers screened within
ABL waste materials (ABL-PZ-15 through ABL-PZ-19) (Environeering, 2012b). Fluoride has not previously
been detected above the NC 2L standard in any perimeter groundwater monitoring well surrounding the
ABL (MW-1 through MW-6).
Subsequent quarterly sampling of the perimeter wells over four quarters (July 11, 2018; October 30,
2018; January 31, 2019; and April 11, 2019) did not identify fluoride above the NC 2L standard in any
perimeter well (Environeering, 2019). As discussed in Section 7.2.2, fluoride -bearing surface water was
identified in the eastern drainage ditch located on the floodplain of Little Mountain Creek and
interpreted to originate from upwelling groundwater. However, concentrations decreased and were
below NC 2L standards in the sample collected closest to Little Mountain Creek (Environeering, 2018c).
Fluoride has historically been detected above NC 2L groundwater standards in the former Main Plant in
the vicinity of the On -Site Landfill and the West Fill Area. Fluoride concentration contours in
groundwater at the former Main Plant are presented in the 2012 CMS Phase 3 study (Environeering Inc,
2012b) and are reproduced on Figure 7-1. The distribution of fluoride and cyanide impacts in
groundwater reflect contributions from multiple sources, particularly in the northern area of the Facility
where numerous SWMUs have historically been identified.

detected available cyanide in groundwater at piezometers screened within the waste materials at the
ABL (ABL-PZ-16 and ABL-PZ-18), and on the floodplain of Little Mountain Creek (ABL-MW-S)
(Environeering, 2012b). All detected available cyanide concentrations in perimeter groundwater
monitoring wells were below the NC 2L groundwater standard. Subsequent quarterly sampling of the
perimeter wells over four quarters (July 11, 2018; October 30, 2018; January 31, 2019; and April 11,
2019) did not identify available cyanide above the NC 2L standard in any perimeter well (Environeering,
2019).
Total cyanide, which does not have an NC 2L groundwater standard, was detected in MW-4 and MW-5
during all four quarters. As discussed in Section 7.2.2, total cyanide was detected in surface water in the
eastern drainage ditch located on the floodplain of Little Mountain Creek and interpreted to originate
from upwelling groundwater. Total cyanide concentrations were above NCAC Rule 213 fresh surface
water quality standards (NCAC 2B) in all three surface water samples (Environeering, 2018c). However,
total cyanide was not detected above NCAC 213 surface water standards in surface water samples from
Little Mountain Creek.
Available cyanide was detected above NC 2L groundwater standards in the former Main Plant in the
vicinity of the On -Site Landfill and the West Fill Area in 2011 (Environeering, 2012b). Available cyanide
concentration contours in groundwater at the former Main Plant presented in the 2012 CMS Phase 3
study (Environeering Inc, 2012b) are reproduced on Figure 7-2.

available cyanide (Figure 7-2). The order of magnitude decreases in fluoride and available cyanide
concentrations between source areas and the shore of Badin Lake is consistent with lake water
recharging and mixing with groundwater and lowering COI concentrations and then migrating to the
south (away from the Lake). Note that these contours are drawn lumping together fill and native soil
wells, and are intended to illustrate the hydrogeological and geochemical attenuation mechanisms
operating at the Main Plant.
Overall, lake water and areas of groundwater recharged by precipitation are buffered at low pH values
due to the reaction with atmospheric carbon dioxide, which is common for similarly low alkalinity
waters (Tailing, 2010). In contrast, areas where groundwater is or has been in contact with SPL typically
have high (alkaline) pH values (Randell Environmental Consulting, 2016). pH values of groundwater at
the former Main Plant were measured during the CMS Phase 3 work (Environeering Inc, 2012b) and the
results were contoured and presented on Figure 7-3. Areas where the pH is above approximately 8.0
standard units correspond to where fluoride and available cyanide are highest, in and around the On -
Site Landfill.

Geochemistry
To better understand geochemical controls on the orders of magnitude decrease in fluoride
concentrations over small distances at the former Main Plant, the Geochemists' Workbench° (GWB)
software application Act2 was used to demonstrate equilibrium constraints on mineral solubility that
control fluoride concentrations in groundwater (Figure 7-4). Above a pH of about 8 standard units,
calcite' replaces fluorite as the stable calcium phase, and there is no theoretical limit on fluoride
concentrations in groundwater contacting SPL because calcite does not contain fluoride in its structure
(i.e., calcite = CaCO3). Below a pH of about 8 standard units, calcium is replaced by fluorite as the stable
calcium mineral phase. The mineral fluorite does contain fluoride in its structure (i.e. fluorite = CaF2) ,
and limits the maximum possible fluoride concentration at equilibrium (McMahon et al., 2020). There
are different variables to this model that would result in different fluoride concentrations in equilibrium
with fluorite, but the key point is that at near -neutral pH and with sufficient calcium, maximum fluoride
concentrations (mg/L) in groundwater are limited by mineral solubility.

Figure 7-4 pH Dependence of Fluoride Mineral Solubility
Based on this model, fluoride concentrations above single digit to low double digit concentrations can
only persist in high pH waters, or acidic waters. Mixing between high pH groundwater with elevated
fluoride and low pH groundwater sourced from Badin Lake would shift pH conditions into the fluorite
3 Calcite is used in this GWB model, but other common carbonate minerals could play a similar role (e.g., siderite, dolomite, or
huntite).

stability range shown on Figure 7-4, leading to fluoride attenuation. Additionally, mixing with lake water
would also lead to lower fluoride concentrations. Consequently, the high fluoride concentration gradient
shown on Figure 7-1 may be explained by geochemical attenuation by mineralization and mixing
between Badin Lake water and former Main Plant groundwater.
Cyanide solubility is also strongly affected by pH. The solubility of cyanide -contaminated soils is highest
at high pH values and lowest at more acidic (lower) pH values (Ghosh et al., 2004). Therefore, mixing
across a pH gradient is also expected to affect available cyanide concentrations through geochemical
attenuation processes.
In addition to mixing and geochemical attenuation lowering cyanide and fluoride concentrations,
groundwater migration from anthropogenic and industrial fill areas in the northern portion of the
former Main Plant is limited by the geologic conditions. The isolated areas of fill materials are generally
underlain or surrounded by native saprolite and residual soil or fill derived from these materials. COls
are rapidly attenuated in the isolated areas where the fill is in communication with the PWR system
through the geochemical processes described above.
7.2 Surface Water
7.2.1 Bodin Lake
During the CMS Phase 3 study (Environeering, 2012b), surface water temperature and conductivity
measurements were made along the shoreline of Badin Lake to identify if groundwater seeps were
present. No groundwater seeps were identified. Surface water samples were then collected from seven
locations along the shoreline of Badin Lake. The sampling location map (Figure 3-20 [Environeering,
2012b]) is provided as Figure 7-5. Grab samples were analyzed for free cyanide, fluoride, TCE, PCBs,
PAHs, and standard field parameters (i.e., pH, specific conductivity, dissolved oxygen, temperature,
turbidity, and ORP). The monitoring was conducted in November 2011 and again in May 2012.

Figure 7-5 2011 and 2012 Badin Lake Surface Water Samples
The November 2011 results identified fluoride in the laboratory method blank, and samples from this
period were noted with a "B" qualifier by the lab. It is believed that the reported value is the result of a
laboratory artifact; it also noted that the reported values of 0.090 to 0.13 mg/L are typical of
background surface and groundwater fluoride concentrations in the United States (McMahon et al.,
2020). Fluoride was not detected in the subsequent sampling event in May 2012. Free cyanide, TCE,
PAHs, and PCBs were not detected in the November 2011 and May 2012 sampling events. The Badin
Lake surface water analytical results are provided in the CMS Phase 3 report (Table 3-6 of Environeering,

The surface water results provide an additional line of evidence that Badin Lake is a losing water body
that is contributing to groundwater recharge beneath the Facility.
7.2.2 Little Mountain Creek
From January 6, 1997 through January 4, 2001, monthly surface water samples were collected from
Little Mountain Creek at points upstream and downstream of the ABL and analyzed for total cyanide,
free cyanide, and fluoride. Results are provided in the 2001 RFI (MFG, 2001). Total cyanide was below
the detection limit in all upstream samples and exceeded NC 02B surface water quality standards nine
times in the downstream samples. Available cyanide exceeded standards two times in the upstream
samples and three times in the downstream samples. Fluoride was below standards in all samples and
exceeded standards three times in the downstream samples. Of the most recent samples from this
dataset (January 2000 through January 2001), only total cyanide exceeded standards in a single sampling
event.
During the 2001 RFI, no COls were detected at concentrations exceeding applicable human health
screening values in Little Mountain Creek (MFG Inc, 2001). During the CMS Phase 3 study
(Environeering, 2012b), a surface water sample was collected from Little Mountain Creek in November
2011 and analyzed for available cyanide, fluoride, TCE, PAHs, and PCBs. Similar to the Badin Lake surface
water sample, fluoride was detected in the laboratory method blank sample and the concentration was
attributed to a laboratory artifact. Consistent with the RFI (MFG Inc, 2001), available cyanide, TCE, PAHs,
and PCBs were not detected in the November 2011 sample from Little Mountain Creek.
To address the January 23, 2017 NCDEQ request for additional investigation downgradient of the ABL
(NCDEQ, 2017), and to assess the variation on constituent levels in Little Mountain Creek as intended by
the instream monitoring study requirements of the September 29, 2017 Final NPDES Permit Renewal
(Condition A. [8]), five surface water samples were collected from Little Mountain Creek (Environeering,
2018c). Fluoride was below NCAC 213 standards in all samples, and total cyanide was not detected in any
sample. The sum of the detected PCB congener concentrations was reported above the NCAC 2B criteria
of one part per trillion in one location; however, congeners were not detected in the duplicate sample.
One sample and the associated duplicate sample contained concentrations of total PAHs exceeding
NCAC 213 standards. As part of the same effort, two sediment samples were collected from Little
Mountain Creek and analyzed for PCBs and PAHs; results did not exceed the applicable screening criteria
(Environeering, 2018c). Subsequent confirmation sampling of Little Mountain Creek surface water and
analysis for PCB congeners and PAHs from the location where the detections occurred did not identify
any constituents above the primary or duplicate sample that was collected (Badin Business Park LLC,
2019).
The most recent sampling events suggest that conditions in Little Mountain Creek have improved, and
current conditions will be assessed during the forthcoming baseline ecological risk evaluation study.
Notably, operation of the ABL corrective measures have likely improved conditions since the 2018
sampling, as described in Section 9.1.

Periodic exceedances of fluoride above the NPDES permitted levels have occurred at Outfall 005.
Subsequent studies have identified that impacted groundwater was entering the storm sewer system

storm sewer pipe invert elevations to identify where the groundwater potential was sufficient to enter
the storm sewer system. Since groundwater at the former Main Plant is confined within PWR, the
analysis was repeated to assess where the Stormwater system intersects the PWR; results are provided
in Section 8.2. Further efforts to locate where stormwater is entering the stormwater system included a

camera study in September 2015 to visually identify areas where groundwater is infiltrating the
stormwater system that feeds into Outfall 005.
Subsequent efforts focused on defining groundwater fluoride or cyanide concentrations in the West Fill
and downgradient areas, along with track down studies of fluoride and cyanide concentrations in the
stormwater system. Mitigation initiatives included upgrades to the stormwater system through
construction of a shallow piping system as part of a special order by consent dated July 2, 2018.
Additionally, portions of the aged stormwater pipe were grouted in 2019, the pipe was isolated with
brick headers, and a slurry wall was installed to mitigate groundwater infiltration to the storm system.
An electrical conductivity survey was subsequently performed to identify the effects of mitigation
measures on groundwater migration.
This section describes the concentrations identified at Outfall 005 that are driving the stormwater
assessment activities and the results of the measures taken. This section also provides an updated
conceptualization of groundwater interaction with the stormwater conveyance system, which has been
informed by the recent hydrogeologic data and conceptualization provided in this report.
8.1 Outfall 005
Concentrations of fluoride at Outfall 005 and manhole (MH) 2.050 (locations shown on Figure 8-1) were
measured over several days in December 2019 (Figure 8-2). On December 11, 2019, about 0.5
cumulative inches of rain fell. On December 13, 2019, about 1.75 cumulative inches of rain fell. Fluoride
concentrations were lower on December 13 than on December 11 in both locations, but the
concentration decreased more in Outfall 005 than in MH 2.050. MH 2.050 was also found to have a
more consistent flow rate during the rain events than Outfall 005. Therefore, the high -fluoride water
from MH 2.050 was diluted more at Outfall 005 during the stronger rain event. Based on this data, it was
concluded that the source of fluoride at Outfall 005 is the baseflow of groundwater in the system and
not mobilization of fluoride from other sources by precipitation. Furthermore, removing high -fluoride
water from MH 2.050 or blending water with a clean water source (from stormwater, groundwater, or
some other source) were identified as possible options for achieving compliance at Outfall 005.

8.2 Stormwater System — Groundwater Interaction
During excavation and plugging activities southwest of MH 2.600 in 2019, it was observed that pipe
bedding may not have been used during the original installation of the stormwater infrastructure and
that native fill materials were likely used instead in many locations. Consequently, the fill material
surrounding the pipe does not likely provide a substantial preferential flow pathway for groundwater,
which is supported by the absence of bends in groundwater equipotential lines around the stormwater
infrastructure.
Based on boring logs for wells MW-103 and MW-220 in the former Main Plant, groundwater was
encountered within PWR or rock and was confined beneath the approximately 10- to 12-foot-thick
veneer of clayey fill. Subsequent water levels measured in the wells were above the PWR/Rock interface
with overlying fill.
To better identify where groundwater is entering the stormwater system, locations where the
stormwater pipe intersects PWR were assessed. Assessing the interface provides a more accurate
measure of where groundwater enters the stormwater system than using the groundwater elevation,
given that groundwater is confined and located within the PWR or rock and may appear artificially high.
The depth to PWR shown on Figure 5-5 was converted to the PWR elevation and compared to the
stormwater pipe invert elevations. The result is shown on Figure 8-5 and corresponds to areas where
there are observed increases in fluoride concentrations within the storm sewer.

Stormwater System
Whereas the stormwater pipe intersects PWR in the section of pipe between MH 6.020 and MH 6.921,
fluoride -impacted groundwater is not believed to be entering the system in this section of pipe due to
fluoride concentrations measured during stormwater track down studies (Section 8.3).
8.3 Track Down Analytical Data
Grab water samples were collected from MHs along the stormwater conveyance that feeds into Outfall
005 at five different times in 20194 to identify the times and locations where fluoride and cyanide were
entering the stormwater piping. Sampling locations and the range of analytical results are shown on
Figure 8-6. Note that a concentration of 24.9 mg/L fluoride was measured in MH 2.200 in September
2019, whereas all previous samples in 2019 and subsequent samples in 2021 were within a range of 2.7
to 4.7 mg/L. Given that no groundwater or other source within the stormwater system has a similarly
high reported concentration, this value is considered suspect. Also, in September 2019, the pipe was dry
upstream at MH 2.510 and dry downstream at MH 2.100 and MH 2.000, suggesting any water in the
intervening space was stagnant and arrived from an upstream location (such as from between MH 2.400
and MH 2.210) at an earlier time and may have concentrated due to evaporation.

collected from five temporary wells (TW001 through TW005) installed to intercept groundwater, a seep
that developed at the base of the embankment east of the West Fill area, and two sumps installed to
manage the water (North Sump and South Sump). Sampling locations and analytical results are shown
on Figure 8-7. Also shown on Figure 8-7 are analytical results for groundwater samples collected and
analyzed in 2022 (Section 3).

Samples were collected using clean disposable sampling equipment and placed into laboratory -provided

Carolina -certified analytical laboratory for analysis (Eurofins of Savannah, Georgia). Samples were
analyzed for fluoride by USEPA Method 300.0 and total cyanide by Method 901213. Laboratory analytical
results are provided in Attachment G.
The following summarizes the spatial distribution of analytical results:
• Analytical results identify groundwater samples collected upgradient (west) of the West Fill Area
as below the method detection limit for fluoride and cyanide (B300 through B303, B305, MW-
218, and MW-39). Fluoride was detected at low levels and below the NC 2L groundwater
standard in MW-219, and total cyanide was not detected.
EHS Support LLC 61

Hydrogeological Conceptual Site Model Update — Badin Business Park
Stormwater System
• Samples from monitoring wells installed in or immediately downgradient (east) of waste
material at the West Fill Area had groundwater fluoride concentrations of 6.3 to 100 mg/L and
cyanide of 0.21 to 12 mg/L.
• At the base of the embankment adjacent to the West Fill Area, groundwater fluoride
concentrations ranged from 1.2 mg/L to 11 mg/L, and total cyanide ranged from below the
detection limit to 0.092 mg/L (TW001 through TW005, south sump, north sump, West Fill area
seep, and BF-5).
• For groundwater further downgradient, total cyanide was below the detection limit in all
groundwater samples and fluoride was below the NC 2L standard in all samples (FO-02, BF-5,
MW-31, and MW-103).
• Within the stormwater conveyance system, fluoride and total cyanide concentrations were
lower than groundwater at the base of the West Fill Area embankment but higher than
groundwater at FO-02, BF-5, MW-31, and MW-103. There is a notable increase in fluoride
between MH 2.400 and MH 2.210 in 2019 and between MH 2.510 and MH 2.210 in 2021. This
stretch of the stormwater system coincides with an area where the stormwater system
intersects PWR (Figure 8-5).
Track down analytical results, along with the identification of where the stormwater conveyance
intercepts PWR, are consistent with the camera study, which identified groundwater infiltrating the pipe
downstream of MH 2.400 and standing water in the pipe between MH 2.320 and MH 2.330.
To summarize, groundwater fluoride and cyanide concentrations increase from non -detect to elevated
concentrations as groundwater moves past the West Fill Area. This is possible because the West Fill Area
was developed in a historical ravine. Saprolite is only a few inches thick (MW-34, MW-37, MW-39) or
absent (MW-38) at the base of the ravine and was likely eroded by natural processes prior to plant
development in this location or was possibly excavated during Facility development and operations. The
CMS Phase 3 Report (Environeering, 2012b) describes this ravine as being filled during plant expansion
and modernization with native soils and incidental amounts of plant process remnants. Groundwater
confined within the PWR moves vertically upward into overlying fill material where native soils were
naturally eroded.
The geologic setting provides a mechanism for the formation of a seep at the base of the West Fill
embankment and for impacted groundwater to mix with cleaner groundwater on the flat area of the
former Main Plant where concentrations decrease. Impacted groundwater enters the stormwater
system in this general area (northeast of MH 2.510). This is the general area where the pipe was
cemented and plugged in 2019, which led to improvements in fluoride concentrations observed at
Outfall 005. Increases in fluoride in stormwater within the conveyance system indicate impacted
groundwater is entering the system between MH 2.510 and MH 2.210 in an area where the pipe
intersects groundwater within PWR. This overall conceptualization is summarized on Figure 8-8.

ABL-Specific Hydrogeology and Efficacy of ABL Corrective Measures
9 ABL-Specific Hydrogeology and Efficacy of ABL Corrective Measures
The geology in the ABL area is generally similar to the former Main Plant and consists of a PWR
groundwater flow system that is recharged from the direction of the former Main Plant and from the
slope to the west. Before waste was placed, there was a bifurcated valley underlain by several feet of
saprolite soils, followed by PWR, and fractured rock based on boring logs and cross sections from the RFI
and CMS Phase 3 reports (MFG Inc, 2011 and Environeering, 2012b, respectively). Historical aerial
photos do not indicate any disturbance of this surface before placing municipal refuse, process material,
and native soils, and subsequent capping, which raised the ground surface from 13 to 42 feet
(Environeering, 2012b). A geologic cross section of the ABL from the 2001 RFI (MFG Inc, 2001) is
provided as Figure 9-1.

The ABL was rough graded in 1980 using available on -site soils and was seeded with grass. In October
1997, the ABL surface was regraded to control run-off and establish a slope suitable for mowing. A new
cover system was established over the landfill area comprising 12 inches of silty clay soil, compacted to
95 percent relative density, overlain by a 6-inch vegetative layer consisting of silty clay soil combined
with lime and fertilizer. Run-on from high areas was managed by installing both lined and unlined
ditches along the flanks of the ABL that are keyed into saprolitic soils and discharge clean water (water
coming onto the Facility) to the flood plain of Little Mountain Creek. These ditches also receive runoff
from adjacent slopes, which include two electrical substations. A subsequent investigation identified
waste beneath an adjacent Alcoa Power and Generating, Inc. high voltage electrical substation
(Environeering, 2008).

Hydrogeological Conceptual Site Model Update — Badin Business Park
ABL-Specific Hydrogeology and Efficacy of ABL Corrective Measures
Geology at the toe of the ABL differs on the floodplain of Little Mountain Creek, where fluvial processes
eroded and thinned residual soils and saprolite and deposited alluvial sediments on the resulting
surface. Alluvial sediments were historically identified in the boring logs for ABL-MW-3, ABL-MW-4, ABL-
MW-5, and ABL-PZ-3S, and in the soil profile at PZ18RD during drilling in 2022. The alluvial soils consist
of organic silt and clay with pebble to cobble -sized rock fragments and roots in places. The alluvial soils
are generally described as wet to saturated and underlain by residual soil and hard, dry saprolite. No
wells are exclusively screened in alluvial soils (Table 6-1), however, given the silty composition and
observed saturation likely have higher hydraulic conductivity than saprolite and residual soil.
Sources of water to the alluvial soils are precipitation and runoff from the ABL cap and slopes on the
eastern and western sides of the floodplain, and groundwater. Overall, groundwater is confined in PWR
beneath saprolite based on periodic flowing artesian conditions in ABL-MW-3 and an upward vertical
groundwater gradient beneath the floodplain (Section 6.3). The strong upward vertical groundwater
gradient provides a source of recharge to the floodplain and associated wetland areas that exist within
this floodplain. Historically, leachate exited to the floodplain, however, this source has been eliminated
through construction of the leachate collection system and subsequent improvements as described in
Section 9.1. However, it cannot be ruled out that residual contamination from this historical condition
persists, and this possibility will be assessed during investigation activities planned for 2023 and the
HCSM will be updated accordingly.
Little Mountain Creek is incised into the PWR with bedrock observed within the creek both upstream
and downstream of the Facility. Groundwater within the PWR (from both sides) discharges to the creek
with baseflow maintained by PWR groundwater discharges throughout the catchment. The connection
between PWR and the creek was documented on the log for ABL-PZ31, which noted bubbles rising in the
creek 50 feet upstream and downstream of the drilling location while drilling in to the PWR with an air
hammer rig.
Groundwater elevations and concentrations were assessed in piezometers installed within the fill
material (PZ-13 through PZ-19) during the Phase 3 CMS Study (Environeering, 2012b). At this time the
two most northerly piezometers were dry (PZ-13 and PZ-14), whereas the more southerly piezometers
(PZ-15 through PZ-19) contained water. Of these piezometers, available cyanide was detected in PZ-16
and PZ-18 although concentrations were below NC 2L standards. Fluoride in groundwater was above
standards in PZ-15 through PZ-19. These results indicate that at that time, waste was saturated in the
lower portion of the landfill below PZ-15 through PZ-19. Time series data are not presently available to
identify if the water in these is stagnant and isolated, or if water levels were affected by construction of
the collection trench at the toe of the ABL.
As shown in Figure 9-1, the waste material within the ABL is enveloped within a combination of saprolite
and native (silt/clay) fill materials that have low permeability (consistent with the hydraulic conductivity
data described for the Main Plant Area). Recharge through the landfill cap is limited, and based on the
low permeability of the saprolite and fill, limited to no lateral migration will occur into the landfill waste
within the shallow fill and saprolite materials. The only areas of groundwater in contact with the waste
materials occurs at the toe of the landfill (as shown below) due to the vertical migration of groundwater
from the PWR through the saprolite and into the fill. The low permeability of the saprolite limits the
magnitude of this vertical flux and the resulting water volumes recovered by the downgradient
groundwater recovery trenches (note these are not shown on the Figure 9-1 cross-section).

ABL-Specific Hydrogeology and Efficacy of ABL Corrective Measures
9.1 Efficacy of ABL Corrective Measures
Corrective measures undertaken at the toe of the ABL are described in Section 2.5.2. As described in
Section 2.5.2, the motivation for the design of a slurry wall, capture trench, and subsequent
improvements (Figure 9-2) was to address the seeps that developed at the base of the ABL following the
completion of the interim measures, which consisted of installing an improved cover system with lateral
drains (Environeering, 2015). A portion of the seep water was believed to originate upslope of the ABL
due to precipitation infiltration and a portion from recharge from bedrock through the base of the ABL.
Historical analytical data suggests the seeps emanate from water that passes through the ABL materials
or makes contact with residual impacts in the floodplain of Little Mountain Creek that arrived before the
cover system improvements were implemented. Section 9.2 describes the efficacy of the remediation
system.

main is compared to the daily precipitation measured at the National Oceanic and Atmospheric
Administration weather station located in Albemarle, North Carolina (Station USC00310090) (Figure

improved following the 2017 modification, which rapidly drained groundwater that had accumulated

under 5,000 gallons recovered per day over the remainder of 2017.

Figure 9-3 ABL Collection Trench Recovery Volumes Compared to Daily Precipitation Totals
Since 2018, the daily recovery volumes from the collection trench have varied on the order of months by
tens of thousands of gallons. There is a correlation with individual precipitation events (Figure 9-3), and
hurricane events in 2018 correlate increased recovery as do precipitation events in 2019. Recovery
spikes in 2019 that are not associated with precipitation events are tied to system modifications to the
collection system operation. A much better visual correlation is apparent when the recovery data is
compared to a 30-day running average of precipitation (Figure 9-4). The result suggests that the
increased recovery volumes are not associated with direct precipitation runoff from the landfill cap or
local precipitation accumulation on the Little Mountain Floodplain. The good match with the 30-day
running total is indicative of groundwater capture by the collection trench; a time -averaged approach is
representative of water storage and seepage that occurs in a groundwater system as opposed to the
instantaneous effects expected for the water sourced from sheet flow runoff.

To summarize, recovery volume data support the following conclusions:
1. The slurry wall is effective for minimizing groundwater mass flux to the floodplain of Little
Mountain Creek as groundwater backed up behind it.
2. The 2017 modifications to the collection trench resulted in the effective capture of
groundwater, as indicated by an initial rapid decrease in recovery volumes when water stored
behind the slurry wall was drained.
3. The collection trench continues to operate as designed by capturing significant volumes of
groundwater.
9.3 Electrical Conductivity Surveys
Delineation of the extent of elevated constituent levels in the area downgradient of the ABL and the
effectiveness of the collection trench system is monitored using electromagnetic (EM) surveys to
measure the electrical conductance in soil pore water. The method allows for correlation between
inorganic water chemistry data and data from electrical -based geophysical methods (Benson et al,
1985). The method can also be used for time -series measurements to evaluate concentration trends
(Benson et al., 1985).
An EM geophysical study was performed quarterly for one year, starting in the second quarter of 2018,
to evaluate the potential for seasonal variability in soil pore water conductivity. The reference baseline
surveys are compared to the subsequent geophysical surveys. Annual surveys are conducted in early fall,
and the results are communicated to NCDEQ; the most recent round of data for 2022 was submitted to
NCDEQ in December 2022.

Hydrogeological Conceptual Site Model Update — Badin Business Park
ABL-Specific Hydrogeology and Efficacy of ABL Corrective Measures
Results of the initial geophysical survey conducted in the third quarter of 2018 are shown on Figure 9-5.
Areas of low apparent conductivity (less than 50 milli5iemens per meter [mS/m]) correlate with
groundwater samples collected in October 2018, where fluoride concentrations ranged from 0.078 J to
0.23 mg/L (ABL-MW-3 through ABL-MW-S; "J" qualifier indicates a concentration between the method
detection and reporting limits), below the NC 2L standards (Environeering Inc., 2019). Available cyanide
in the samples from the same wells ranged from 0.00031 J mg/L to 0.0025 mg/L, which is also below the
NC 2L standard.
Contemporary data for groundwater samples from high apparent conductivity areas is not available;
monitoring wells ABL-MW-8 through ABL-MW-13 were abandoned during construction of the collection
trench and groundwater concentration data has not previously been reported. However, groundwater
concentrations for piezometers PZ-15 through PZ-17 are available from the Screening Level Ecological
Risk Assessment Report for the ABL (CEC, 2021b). PZ-15 through PZ-17 are located within the footprint
of the landfill, and between August 2011 and August 2012 fluoride concentrations ranged from 8.9 to 77
mg/L (except one non -detect concentration at PZ-16 in May 2012). Over the same period, available
cyanide ranged from not detected to 0.014 mg/L. These results indicate that apparent conductivity
provides a useful measure of the spatial extent of impacted groundwater. It is anticipated that the suites
of analyses collected during the Baseline Ecological Risk Assessment process will enable improved
calibration of the apparent conductivity data.
A comparison of temporal apparent conductivity trends is provided through the comparison of fall 2018
with fall 2022 apparent conductivity results (Figure 9-5 and Figure 9-6, respectively). Results show a
notable decrease in the extent of apparent conductivity above 50 mS/m, which indicates the collection
trench is effective.

9.4 Source of Constituents of Interest
The RFI results showed no COls were present in the soil adjacent to the ABL at concentrations exceeding
the conservative risk -based screening values; therefore, soils surrounding the ABL do not pose an
unacceptable risk to potential current or reasonably anticipated future receptors. However, the RFI did
show that cyanide in groundwater exceeded the screening value in a single well downgradient of the
ABL. A screening level risk assessment was conducted on Little Mountain Creek, the first receptor for
groundwater downgradient of the ABL. No COls were present at concentrations exceeding applicable
human health screening values. However, the unit was retained in the corrective action process because
of the one detection of total cyanide in groundwater above the regulatory standard (Environeering,
2012a).
In 2018, surface water and sediment samples were collected from Little Mountain Creek and the eastern
drainage ditch, a feature located on the eastern side of the Little Mountain Creek floodplain that is
keyed into alluvium and receives both artesian and lateral runoff (Environeering, 2018c). Fluoride and
total cyanide were below regulatory standards in the surface water from Little Mountain Creek but were
detected above criteria in surface water from the eastern drainage ditch. Fluoride and cyanide were
below criteria in the eastern drainage ditch sample closest to Little Mountain Creek. PAHs were above
criteria in a single sample from the central ditch, and above criteria in a single Little Mountain Creek
surface water sample from across Highway 740, which was attributed to an off -site source. PCB
congener concentrations were above criteria in a single surface water sample from Little Mountain
Creek but were not detected in the duplicate sample. PCB congener concentrations were above criteria
in sediment samples from the middle and lower ditch sediment samples. It is documented that there

was a fire due to a bushing failure at the adjacent substation on the opposite side of the eastern ditch
from the ABL and that the substation is at a higher elevation than the eastern ditch and is in the
upgradient direction of surface runoff.
Surface water samples collected in September 2020 confirmed that fluoride and total cyanide were
below regulatory standards in the surface water of Little Mountain Creek and that fluoride and total
cyanide were above criteria in surface water samples from the eastern drainage ditch feature located on
the eastern side of the Little Mountain Creek floodplain (CEC, 2021a).
Potential sources for COls on the floodplain of Little Mountain Creek include waste beneath the adjacent
substation that was identified during drilling in 2007 (Environeering, 2008), historical releases from one
of the two adjacent electrical substations, or residual impacts that entered the floodplain prior to
finishing the ABL cap and collection trench system. Additional data to be collected from supplemental
sampling planned for 2023 in this area is expected to provide additional constraints on the source of
impacts. Elements of this HCSM document will be updated as new sampling data becomes available.

Conclusions
10 Conclusions
The Facility differs from typical Appalachian Piedmont hydrogeological systems (Figure 1-1) because of
extensive excavation, placement of fill, and leveling of topography. Key differences between the Facility
and typical Piedmont hydrogeological flow systems are shown conceptually on Figure 1-1 and Figure
1-2. The primary difference is that low permeability residual soils and saprolite have been excavated
from underlying PWR over much of the former Main Plant, and PWR/rock is the only water -bearing unit
present. In other areas, fill derived from low -permeability native materials was used to fill ravines.
Groundwater at the former Main Plant is recharged from the hillside to the west and from Badin Lake to
the east. Lake water enters the groundwater system through PWR and fractured rock, which are
exposed on the lake bottom and along the lake shore. PWR or fractured rock is present across the
former Main Plant and ABL and has modest hydraulic conductivity. The orientation of bedding and
fractures in the PWR/rock affect groundwater flow directions and COI fate and transport at the Facility
and direct the groundwater flow toward the ABL where it discharges toward the floodplain of Little
Mountain Creek and is captured in part by the ABL collection trench.
Fill has locally higher hydraulic conductivity than PWR/fractured rock, however, it is present in isolated
locations and generally underlain by low permeability saprolite and residual soils and surrounded by
native soils used as fill. The isolation of fill areas limits migration of COls in groundwater, except in
localized areas where saprolite has been eroded or excavated. Remediation measures further limit
infiltration into and seepage from areas of anthropogenic fill, including caps installed at the On -Site
Landfill, ABL, and West Fill areas.
In localized areas where saprolite was eroded by natural processes, fill is in contact with PWR or
fractured rock. COls that enter the PWR groundwater system rapidly mix with clean groundwater
recharged from Badin Lake and upslope areas and are also geochemically attenuated through
mineralization due to the strong pH gradient between source areas and recharge areas. A combination
of vertical groundwater gradients, groundwater flow primarily through PWR and fractured rock, and
geochemical attenuation appear to be the primary controls on plume geometry at the former Main
Plant.
Due to the effects of the structural geology, the presence of Badin Lake and potential leakage into the
storm sewers in the south, groundwater flow at the Facility is directed away from Lake Badin towards
Little Mountain Creek. Some small, localized areas of granular fill may have components of groundwater
flow in other directions, however, these flow regimes are minor and likely to only be present for short
periods of time because water rapidly leaks into the deeper PWR unit.
In the context of the ABL, the groundwater flow regime is towards Little Mountain Creek. Generally,
vertical gradients in the higher elevation areas are downward with limited water encountered in the fill
and saprolite. While in the lower elevation of the ABL, vertical gradients reverse with groundwater from
the PWR moving vertically upward into the saprolite, fill, and in the floodplain area alluvial deposits.
Little Mountain Creek is incised into the PWR and all groundwater in the area (from both sides of the
river) discharges to Little Mountain Creek. Baseflow within Little Mountain Creek is maintained by the
flow of groundwater into this system.

Conclusions
Large fluoride and cyanide plumes are not observed on the Main Plant due to the combination of
geochemical processes and the dilutionary effects of Badin Lake water entering the PWR and flowing
south toward Little Mountain Creek. While impacts are present within the immediate vicinity of the
SWMUs, these have been shown to rapidly attenuate. Since completion of the last major groundwater
sampling event in 2011, Facility operations have terminated and capping and remedial works have been
completed. This combination of actions, coupled with natural attenuation processes, have likely resulted
in major declines in groundwater concentrations. The planned comprehensive groundwater sampling
event in the first quarter of 2023 will update our understanding of current conditions.
The source of fluoride exceedances at Outfall 005 is infiltration of groundwater into the aged
stormwater conveyance system. Recent efforts to plug the piping have resulted in material benefits and
lowering of fluoride concentrations at Outfall 005. Fluoride -impacted groundwater is still entering the
piping in areas where infrastructure intercepts the PWR. Supplemental investigations planned for 2023
are aimed at verifying this conceptualization and arriving at an appropriate mitigation measure.
Corrective measures undertaken at the ABL are effective at capturing groundwater and apparent
conductivity surveys indicate that the footprint of impacted groundwater beneath the floodplain of
Little Mountain Creek is decreasing in size. A comprehensive program of evaluations is being planned for
the floodplain of Little Mountain Creek in 2023. The expectation is that this HCSM will be updated as
new data becomes available.

Receipt
The samples were received on 8/19/2022 9:30 AM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperatures of the 2 coolers at receipt time were 2.0°C and 2.9°C
HPLC/IC
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
General Chemistry
Method 1677_Free: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 180-410147 were outside control
limits. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control sample (LCS)
recovery was within acceptance limits.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Narrative
CASE NARRATIVE
Client: Civil & Environmental Consultants Inc
Project: Alcoa - Groundwater & Waste Characteriza
Report Number: 680-196438-4
With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no
problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control
limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of
the method. In the event of interference or analytes present at high concentrations, samples may be diluted. For diluted samples, the
reporting limits are adjusted relative to the dilution required.
RECEIPT
The samples were received on 03/18/2021; the samples arrived in good condition, properly preserved and on ice. The temperature of the
coolers at receipt was 1.1 C.
FREE CYANIDE

(680-196438-20) were analyzed for free cyanide in accordance with 1677. The samples were analyzed on 03/24/2021.
Cyanide, Free failed the recovery criteria low for the MS of sample Out005-North SumpMS (680-196438-11) in batch 180-350778. Cyanide,
Free failed the recovery criteria low for the MSD of sample Out005-North SumpMSD (680-196438-11) in batch 180-350778. Cyanide, Free
exceeded the RPD limit. Sample matrix interference and/or non -homogeneity are suspected because the associated laboratory control
sample (LCS) recovery was within acceptance limits.
Refer to the QC report for details.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Report Number: 680-182269-1
With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no
problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control
limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of
the method. In the event of interference or analytes present at high concentrations, samples may be diluted. For diluted samples, the
reporting limits are adjusted relative to the dilution required.
RECEIPT I
The samples were received on 04/01/2020; the samples arrived in good condition, properly preserved and on ice. The temperature of the
coolers at receipt was 8.2 C.

Lancaster Laboratories Environmental r Exnlanation of Symbols and Abbreviations
The following defines common symbols and abbreviations used in reporting technical data:
BMQL Below Minimum Quantitation Level mL milliliter(s)
C degrees Celsius MPN Most Probable Number
cfu colony forming units N.D. non -detect
CP Units cobalt-chloroplatinate units ng nanogram(s)
F degrees Fahrenheit NTU nephelometric turbidity units
g gram(s) pg/L picogram/liter
IU International Units RL Reporting Limit
kg kilogram(s) TNTC Too Numerous To Count
L liter(s) Ng microgram(s)
lb. pound(s) pL microliter(s)
m3 cubic meter(s) umhos/cm micromhos/cm
meq mill iequivalents MCL Maximum Contamination Limit
mg milligram(s) ED
< less than
> greater than
ppm parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg) or one gram per million grams. For
aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/1), because one liter of water has a weight
very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter per liter of gas.
ppb parts per billion F
Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
basis concentration to approximate the value present in a similar sample without moisture. All other results are reported on an
as -received basis.
Analytical test results meet all requirements of the associated regulatory program (i.e., NELAC (TNI), DoD, and ISO 17025) unless
otherwise noted under the individual analysis.
Measurement uncertainty values, as applicable, are available upon request.
Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the
collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be
meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held
responsible for sample integrity, however, unless sampling has been performed by a member of our staff.
This report shall not be reproduced except in full, without the written approval of the laboratory.
Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as "analyze immediately" are not performed within
15 minutes.
WARRANTY AND LIMITS OF LIABILITY - In accepting analytical work, we warrant the accuracy of test results for the sample as submitted.
THE FOREGOING EXPRESS WARRANTY IS EXCLUSIVE AND IS GIVEN IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR
IMPLIED. WE DISCLAIM ANY OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING A WARRANTY OF FITNESS FOR
PARTICULAR PURPOSE AND WARRANTY OF MERCHANTABILITY. IN NO EVENT SHALL EUROFINS LANCASTER LABORATORIES
ENVIRONMENTAL, LLC BE LIABLE FOR INDIRECT, SPECIAL, CONSEQUENTIAL, OR INCIDENTAL DAMAGES INCLUDING, BUT NOT
LIMITED TO, DAMAGES FOR LOSS OF PROFIT OR GOODWILL REGARDLESS OF (A) THE NEGLIGENCE (EITHER SOLE OR
CONCURRENT) OF EUROFINS LANCASTER LABORATORIES ENVIRONMENTAL AND (B) WHETHER EUROFINS LANCASTER
LABORATORIES ENVIRONMENTAL HAS BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. We accept no legal
responsibility for the purposes for which the client uses the test results. No purchase order or other order for work shall be accepted by
Eurofins Lancaster Laboratories Environmental which includes any conditions that vary from the Standard Terms and Conditions, and
Eurofins Lancaster Laboratories Environmental hereby objects to any conflicting terms contained in any acceptance or order submitted by
client.
