Alternate Source Demonstration: Metals in Groundwater March 11, 2024
Buncombe County Landfill -Alexander, North Carolina BLE Project No. J22-9378-31M
1.0 PROJECT INFORMATION
The subject 654-acre landfill site is located in Buncombe County, North Carolina, approximately nine miles
north of the city of Asheville with a physical address of 81 Panther Branch Road in Alexander, North Carolina
(Figure 1). Buncombe County owns and operates a Subtitle D MSWLF which includes Cell 1 through Cell
7 and a CDLF consisting of Phase 1 through Phase 7. Currently Cell 7 of the MSWLF and Phase 7 of the
CDLF are the active waste units. MSWLF Cells 8 through 10 are planned (but not permitted) for future
expansion.
A Water Quality Monitoring Plan (WQMP) was finalized by BLE and submitted to the North Carolina Solid
Waste Section (SWS). The WQMP was approved on April 16, 2021 (FID 1576846). The facility requires
semi-annual groundwater, surface water, and leachate monitoring and reporting in accordance with the
WQMP. Semi-annual sampling is typically conducted each April and October and those events are designated
"Spring" and "Fall," respectively.
The existing groundwater monitoring network for the Buncombe County Landfill consists of two (2)
upgradient (background) wells (MW-1 and MW-1D) and twenty-six (26) downgradient (compliance) wells
(MW-2, MW-21), MW-3R, MW-4, MW-41), MW-5, MW-51), MW-6, MW-7, MW-8, MW-8D, MW-10,
MW-IOD, MW-11, MW-11D, MW-12, MW-12D, MW-13, MW-13D, MW-14, MW-14D, MW-16,
MW-16D, MW-17R, MW-17DR, and MW-18). Wells MW-17 and MW-17D were abandoned September
14, 2020 and replaced by MW-17R and MW-17DR, respectively (Figure 2). Wells MW-15 and MW-15D
were removed as compliance points and replaced by MW-18 as approved by the SWS on August 3, 2021
(FID 1595460). The MW-15/MW-15D well pair remains in place for the collection of water levels only. The
current SWS approved monitoring matrix is included as Table 1, and well construction is provided on
Table 2.
In accordance with Rule .0602 and Rule .0544(c), eight (8) surface water monitoring locations have been
established for the facility to monitor surface water quality surrounding the existing waste footprint
(Table 1). The existing surface water locations consist of one (1) upstream (background) point (SW-1) and
seven (7) downstream (compliance) points (SW-2 through SW-8).
In accordance with Rule .1626(12)(c), nine (9) active leak detector and leachate sampling locations have been
established for the facility (Table 1). The locations include seven (7) existing leak detection sampling
locations associated with each MSWLF cell (Cells 1 through 7) designated LD-1 through LD-7, one (1)
leachate leak detection sampling location near the leachate pond designated Leachate LD, and the Leachate
Pond itself.
The DEQ issued new groundwater metals standards (NC2Ls) on April 1, 2022. As part of the updated NC2L
standards, all metals were removed from the Interim Maximum Allowable Concentrations (IMACs) list and
added to the NC2L standards. BLE understands that this change may result in metals compliance issues at
solid waste facilities. BLE understands that solid waste facilities will be allowed to utilize alternate
groundwater protection standards calculated from background wells, perform a limited alternate source
demonstration (ASD), or enter assessment monitoring per the solid waste regulations.
Buncombe County has determined that an assessment of natural site conditions should be performed to evaluate
if the metals detected in the groundwater are naturally occurring and therefore originated from an alternate
source. The findings of this assessment are reported herein.

Alternate Source Demonstration: Metals in Groundwater March 11, 2024
Buncombe County Landfill —Alexander, North Carolina BLE Project No. J22-9378-31M
1.1 Previous SWS-Approved Alternate Source Demonstration
A previous consultant, SCS Engineers, PC (SCS), prepared an Alternate Source Demonstration dated January
3, 2017 (SCS File No. 09204072.13; FID 663667) and an Alternate Source Demonstration Addendum dated
January 30, 2018 (SCS File No. 09204072.13; FID 1088748). The ASD was prepared in response to
exceedances of groundwater protection standards for various metals at the facility. The ASD provided
evidence that the detections and exceedances of these metals were a result of natural variation in groundwater
quality. Alternate groundwater protection standards (AGWPS) were proposed for antimony, chromium,
cobalt, iron, thallium, and vanadium. The AGWPSs were approved by the SWS in their letter to Buncombe
County dated June 5, 2018 (FID 1213927).
2.0 SITE GEOLOGY
The subject site is located within the Blue Ridge geologic belt. The geology of the Blue Ridge Belt consists
of metamorphic Precambrian basement rock overlain with unconformable younger Precambrian
metamorphosed sedimentary and igneous rocks. The Blue Ridge belt is bordered to the southeast by the
Brevard belt and to the northwest by the Valley and Ridge. The Precambrian basement has undergone
several episodes of uplift, deformation, faulting, intrusion, metamorphism, and erosion. Locally, the site is
geologically underlain by Middle Proterozoic biotite granitic gneiss and migmatitic biotite hornblende
gneiss interlayered with amphibolite and calc-silicate rocks (Rhodes and Conrad, 1985; CDM, 2009).
The typical residual soil profile consists of clayey and silty soils near the surface, where soil weathering is
more advanced, underlain by micaceous sandy silts and silty sands. Residual soil zones develop by the in
situ chemical weathering of bedrock, and are commonly referred to as "saprolite." Saprolite usually
consists of micaceous sand with large rock fragments and lesser amounts of clay and silt. The boundary
between soil and rock is not sharply defined.
A transitional zone of partially weathered rock (PWR) is normally found overlying the parent bedrock.
Partially weathered rock is defined, for engineering purposes, as residual material with standard penetration
resistance (ASTM D 1586) in excess of 100 blows per foot (bpf). Fractures, joints, and the presence of less
resistant rock types facilitate weathering. Consequently, the profile of the partially weathered rock and
hard rock is quite irregular and erratic, even over short horizontal distances. Also, it is not unusual to find
lenses and boulders of hard rock and zones of partially weathered rock within the soil mantle, well above
the general bedrock level.
3.0 ALTERNATE SOURCES FOR METALS IN GROUNDWATER
Sediment and bedrock composition directly affect the presence of naturally occurring metals in groundwater
(Chapman et al, 2013). Naturally occurring metals are common in the Blue Ridge geologic belt. Literature
research of the geology and water quality detections of metals in the Blue Ridge geologic belt are listed
below.
3.1 Geology
Naturally occurring metal ores such as chromium, copper, iron, lead, manganese, nickel, silver, and zinc,
occur in the Blue Ridge and Piedmont provinces of North Carolina (Carpenter et al, 1995; Chapman et al,
2013).

3.2 Water Quality
3.2.1 Buncombe County Private Wells
March 11, 2024
BLE Project No. J22-9378-31M
The North Carolina State Laboratory of Public Health performed a study from 1998-2010 investigating
average concentrations of contaminants found in private wells (Tracking and Analyzing Contaminants in
Private Well Water in NC). The study provided average concentrations observed in counties across North
Carolina. Of the 2000+ wells that were involved in the study from Buncombe County, North Carolina,
various metals were detected including: arsenic, barium, cadmium, chromium, copper, iron, lead,
manganese, selenium, silver, and zinc. A summary table of the results from the study, which was published
by the NC Department of Health and Human Services is presented in Appendix A.
3.2.2 Bent Creek Groundwater Monitoring
Groundwater monitoring is performed at the Bent Creek Research Station (BCRS) in Buncombe County,
NC south of Asheville. The primary objective of the BCRS, as described by the NC DEQ, is to characterize
groundwater geochemistry in a pristine, mountain setting. Groundwater geochemistry data, including the
analysis of arsenic, barium, cadmium, chromium, copper, iron, mercury, manganese, nickel, lead, selenium,
and zinc is reported by the DEQ (Bent Creek Groundwater Monitoring and Research Station, NC DEQ).
Concentrations of barium, copper, iron, lead, manganese, and zinc were detected in the groundwater samples
collected at the BCRS which demonstrates that these metals are naturally occurring in groundwater.
4.0 SITE SPECIFIC DATA
4.1 Soil
4.1.1 Background Soils —Total Metals
BLE performed a soil borrow study investigation at the Buncombe County Landfill in the MSW Phase 7 area
(Figure 2). The investigation was performed prior to the construction or operation of the MSW Phase 7. The
soil in the investigation was not impacted by landfill activities, was from a comparable soil profile as the
monitoring wells installed in the residual soil, and was representative of natural in -situ soil across the site.
The study was documented in the Report of Soil Sampling and Analysis: Potential Transfer Station Borrow
Soil, dated June 8, 2017. As part of the investigation, fourteen (14) discrete soil samples were collected above
the groundwater table from multiple depth intervals ranging from ground surface to 10 feet below ground
surface. The soil samples were analyzed for total metals (Sb, As, Be, Cd, Cr, Cu, Fe, Hg, Pb, Mn, Ni, Se, Ag,
Tl, and Zn). Please note that analysis of barium and cobalt were not required for this investigation and
therefore were not included in the analytical suite.
A summary table of the analytical results from the metals analysis is included in Appendix B (Table 3 — Total
Metals and Inorganics). Ten metals were detected in the soil samples collected for the borrow study. The
metals include beryllium, cadmium, chromium, copper, iron, lead, manganese, nickel, thallium, and zinc.
The data indicates that the metals are present in the alternate source (soils) and along the flow path from the
alternate source to the groundwater wells. Additionally, the water table at the site is unconfined and the
aquifer matrix is composed of these soils. There is a hydraulic connection between the soils and the
groundwater wells with metals detections.

4.1.2 Background Soils — SPLP Metals
March 11, 2024
BLE Project No. J22-9378-31M
A background soil sample designated SS-1 was collected from the northeast corner of the site near the
newly constructed Cell 7 (Figure 2) as part of an environmental assessment for a leachate release in July
2023. The soil sample was collected via a hand auger at a depth between one and two feet below ground
surface. The soil sample was analyzed in the laboratory using the Synthetic Precipitation Leaching
Procedure (SPLP). The results were included in the Report of Soil and Surface Water Assessment Leachate
Release — July 2023 dated September 19, 2023, prepared by BLE. BLE requested that the analytical
laboratory reissue the analytical report in February 2024 to include a full suite of metals. A summary table
of the SPLP data is included in Table 3 and the laboratory report is included in Appendix C.
Concentrations of barium, chromium, cobalt, copper, vanadium, and zinc were detected.
4.2 Groundwater
4.2.1 Background Sampling
The facility's monitoring network includes two background groundwater monitoring wells (MW-1 and
MW-11)) which are sampled and reported semi-annually. A summary table of the background metals
detected during the eight most recent semi-annual sampling events (Fall 2019 to Spring 2023) is included
in Table 4. Concentrations of antimony, barium, chromium, cobalt, copper, iron, lead, manganese, nickel,
vanadium, and zinc have been detected.
4.2.2 Baseline Sampling
Baseline sampling is required for wells that are installed as part of future cell development. The baseline
sampling events help to identify constituents that may be present in the groundwater prior to operation of a
waste unit. A summary table of the baseline metals data from groundwater monitoring wells MW-16, MW-
16D, MW-17, and MW-17D are included in Table 5. During the baseline sampling events, concentrations
of antimony, barium, chromium, copper, iron, manganese, nickel, selenium, vanadium, and zinc were
detected.
5.0 COMPROMISED GROUNDWATER MONITORING WELLS: MW-12 AND MW-12D
Historically, metals related compliance issues have been identified in the MW-12/ MW-12D well pair. BLE
investigated the well construction (Appendix D) and the location of the groundwater monitoring well pair
(Figure 2). The MW-12/ MW-12D well pair are installed in close proximity to Sediment Pond 11. The wells
have shallow screen construction, 7-17 feet bgs for MW-12 and 27-37 feet bgs for MW-12D. The water
elevation measured in the wells is approximately 1,936 (ft MSL) which correlated to the approximate pond
elevation measured from the topography on Figure 2.
The MW-14 and MW-14D well pair exists hydraulically down gradient of the MW-12 and MW-12D well pair.
These wells are also sampled semi-annually for the same constituents as the MW-12 and MW-12D well pair.
Historically, the MW-14 and MW-14D wells have lower total metals concentrations than the MW-12 and
MW-12D wells.
The data indicates that the MW-12 and MW-12D wells are likely impacted by the surface water collected in
Sediment Pond 11 and are not representative of the groundwater at the facility.

6.0 FINDINGS AND RECOMMENDATIONS
March 11, 2024
BLE Project No. J22-9378-31M
Based on the information above, the most likely source of various total metals including arsenic, barium,
beryllium, cadmium, chromium, cobalt, copper, iron, lead, manganese, nickel, selenium, thallium,
vanadium, and zinc is the local soils and geology at the facility. This is evidenced by investigations
performed by the NC Department of Health and Human Services, the NC DEQ, the native soils evaluated
at the site, background water quality data, and baseline water quality data.
We conclude from evaluation of the data herein that the metals detected in the site's groundwater (summarized
in the table below) are naturally occurring in the groundwater, and the presence of these metals in the
groundwater is not indicative of a release from the landfill unit.

Additionally, it is our opinion that the metals compliance issues at the MW-12 and MW-12D well pair are
the result of surface water impacts and that the water monitored at those locations is not representative of
the natural groundwater conditions. We recommend that the facility discontinue detection monitoring at
the MW-12 and MW-12D well pair and that the facility replace them with a new well pair (MW-19 and
MW-19D) located near landfill gas monitoring well M-11 (downgradient of MW-12) [Figure 2].

I - Data from Table 3, Well Construction, New Buncombe County Landfill, Buncombe County, North Carolina, provided by SCS Engineers.
2 - Based on visual observation of Sheet No I Groundwater and Methane Monitoring Well Locations by CDM Smith dated August 2014.
Some well installation dates appear inconsistent with water level records and may not be accurate. Changes to some dates (italics) made based on water level records and dates from SHR and DHR documents by CDM.
The top of casing and ground surface elevations for MW-3R are a probable error (reversed) based on April 2016 water levels in the SCS Engineers report.
The top of casing and ground surface elevations for MW-14 and MW-14D do not match those in the SHR and DHR documents by CDM.
The well construction and survey data for MW-17R and MW-17DR are from a report by SCS dated October 13, 2020
The well construction data for MW-16 and MW-16D are from a report by SCS dated December 5, 2022
Location accuracy of the monitoing wells is limited by the references themselves
The well construction data for MW-18 from the DHR table and boring log by CDM. Surveying was performed by Ed Holmes and Associates of Asheville, NC in September 2021.
TOC - Top of Casing.

* Secondary MCL: Secondary contaminants may cause cosmetic effects (such as skin or tooth discoloration) or aesthetic effects (such as taste, odor, or color) in
drinking water.8 The Secondary Maximum Contaminant Level (SMCL) is a non -enforceable standard for secondary contaminants in drinking water. SMCLs may
be based upon a contaminant's likelihood to cause changes to the taste, odor, or color of drinking water, or, may be based on the likelihood of the contaminant
to cause technical changes such as damage to water fixtures or an increased availability of other contaminants in drinking water.8

Case Narrative
Bunnell-Lammons Engineering, Inc.
Lot Number: YG21044
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report. Where
sampling is conducted by the client, results relate to the accuracy of the information provided, and as the
samples are received.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or
discussed below.
Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI
scope of accreditation: Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-
dichloroethane) EPA 524.2, E. coli and Total coliforms SM 9223 B-2004, Solid Chemical Material: TOC
Walkley-Black, Biological Tissue: All, Non -Potable Water: SGT-HEM EPA 1664B, Silica EPA 200.7,
Boron, Calcium, Silicon, Strontium EPA 200.8, Bicarbonate, Carbonate, and Hydroxide Alkalinity SM 2320
B-2011, SM 9221 C E-2006 & SM 9222D-2006, Strontium SW-846 6010D, VOC SM 6200 B-2011, Fecal
Coliform Colilert-18, PFAS by Isotope Dilution SOP.
Where applicable, all soil sample results (including LOQ and DL if requested) are corrected for dry weight
unless flagged with a "W" qualifier.
If you have any questions regarding this report, please contact the Pace Project Manager listed on the
cover page.
The pH analysis associated with the sample(s) in this report was/were performed after the method
recommended 15 minute holding time.
This report supersedes all other versions of the same lot number. Per client request, additional SPLP
metals have been added to sample -001.
Inorganic Non -Metals
For total phosphate analytical batch 80803, the batch quality control parameters (complex phosphate
digestion check standard, limit of quantitation check standard, method blank, and laboratory control
sample) were contained in a bracket in which the continuing calibration blank (CCB) did not meet method
criteria. The CCB recovered slightly greater than the MDL at 0.0211 mg/L, which is less than half the limit
of quantitation (LOQ) at 0.05mg/L. The affected samples either contained detections greater than 1 OX the
value of the failing CCB, or were analyzed in separate brackets in which all method recovery criteria were
met. Sample results are not expected to be impacted by this nonconformity, and the data has been
reported.
VOCs by GUMS
Insufficient sample volume was provided to perform matrix spike/matrix spike duplicate (MS/MSD) for
analytical batch 81279, 80686, and 81182. An LCS/LCSD was run in lieu of an MS/MSD.
Internal standard response for the following sample(s) exceeded the lower control limit: YG21044-003,
YG21044-004. The sample was re -analyzed with concurring results. As such, the sample results may
be biased high. The original set of data has been reported
