Phytoremediation Assessment Report August 23, 2023
Old Buncombe County Landfill — Woodfin, North Carolina BLE Project No. J22-14175-07
1.0 PROJECT INFORMATION
Buncombe County provides post -closure care for the Pre -Subtitle D MSWLF (unlined) located at 2726
Riverside Drive, Woodfin, North Carolina (Figure 1). The county operated the facility as a municipal solid
waste (MSW), industrial solid waste (ISW), and construction and demolition (C&D) landfill. The landfill is
separated into four (4) waste areas labeled A through D. Waste areas A, B, and C stopped receiving waste
before October 9, 1991, and waste area D stopped receiving waste on September 27, 1997.
Groundwater and surface water monitoring is performed at the site in accordance with a SWS approved
Corrective Action Plan (CAP) dated September 3, 2014 [DIN 21838 (SCS Engineers File No 09204072.06)]
and a SWS approved Request for Reduction ofMNA Parameters dated November 30, 2016 [DIN 27144 (SCS
Engineers File No 09204072.14)]. Prior to the second semi-annual sampling event of 2020, BLE submitted
(on behalf of Buncombe County) the Report of 1, 4-Dioxane Sampling and Analysis November 2018 to April
2020 dated September 1, 2020 [FID 145059] which included updated groundwater and surface water matrices.
The report and updated matrices were approved by the SWS.
Buncombe County applied for, and was granted a permit for subsurface injection of materials for enhanced
bioremediation of VOCs (chlorinated solvents) in groundwater as part of the correction action at the facility.
An underground injection control (UIC) Permit (No W10100353) was transmitted by the DWR on September
11, 2015. The permit issue date was September 15, 2015. The permit was renewed on September 21, 2020
and expires on August 31, 2025 (effective dates).
The facility requires semi-annual groundwater and surface water monitoring and reporting in accordance with
the CAP, et seq., and UIC permit.
The selected remedies in the approved CAP include Monitored Natural Attenuation (MNA), Intuitional
Controls, and In Situ Enhanced Bioremediation and Bioaugmentation. The institutional controls included a
restrictive cover (landfill cap), fencing, and a landfill gas collection system.
BLE prepared a Corrective Action Evaluation Report, Water Quality Data Through October 2021 dated
March 30, 2022 [FID 1661864 (BLE Project No. J20-14175-03)] as required in the CAP. The CAER
documented that chlorinated solvents and other classes of VOCs present in groundwater have degraded or
should continue to degrade. However, trends of a limited number of VOCs (1,4-Dioxane [DX] in particular)
indicated that supplemental remedial actions may be beneficial. BLE recommended the evaluation of
phytoremediation as a voluntary supplemental remedy to address the subject VOCs. The CAER indicated
that the evaluation, remedy selection, and corrective action plans should be prepared and submitted in three
(3) phases. The SWS approved the Corrective Action Evaluation Report (CAER) on April 12, 2022 (FID
1664186).
The initial steps in Phase I of the proposed phytoremediation pathway included an assessment of the
condition, type, and efficacy of the existing flora. BLE began work on these tasks in July 2022 after receiving
SWS approval of the CAER. BLE prepared and submitted a document to the SWS titled Update to the
Phase I Phytoremediation Evaluation dated December 15, 2022. The update indicated that the evaluation
was continuing and that the next update would be submitted to the SWS on or before October 31, 2023. The
results and recommendations of the completed Phase 1 assessment are contained herein.

2.0 FIELD ACTIVITIES, SAMPLING, AND ANALYSIS
Three (3) sampling areas of interest were selected based on VOC distribution in groundwater as reported
in the CAER. The three sampling areas were designated Area 1, Area 2, and Area 3 and were located near
the MW-21, MW-19, and MW-18 well pairs, respectively (Figure 2).
Samples were collected during three separate events (August 2022, October 2022, and May 2023) by
personnel from BLE. The samples were delivered to Pace Analytical Services, LLC. (Pace) of Columbia,
South Carolina for each event and analyzed in the laboratory.
2.1 August 2022
Personnel from BLE walked the areas of interest on August 2, 2022. We noted the predominant tree species
within each area included Southern Catalpa, Birch, Hickory, Maple, Tulip Poplar, Sycamore, and Red Oak.
The trees ranged from sapling to fully mature trees up to 9.4 feet in circumference. A total of fifteen (15)
trees from all areas were selected for sampling and analysis [TC-1 through TC-15] (Figure 3). A minimum
of one tree of each species was selected for sampling.
Samples were collected on August 2, 2022. Samples were designated "TC" for Tree Core and included a
numeral identifier for each individual tree (e.g. TC-1) Four (4) samples were collected from each tree. The
samples were collected from four (4) sides of the trees which corresponded to the four cardinal directions
(North, South, East, and West). A suffix identifier (N, S, E, or W) was added to each sample name to
identify the location of the sample on the tree (e.g. TC-1N). Samples were collected from a height of 3 to
4 feet above ground surface at each tree.
Samples were collected utilizing standard methods which included the removal of the outer layer of bark
and phloem and exposing the xylem to be sampled. The tree tissue was removed using cutting tools and a
minimum of five (5) grams of xylem was collected from each sample location. A total of sixty (60) samples
were collected.
Each sample was placed inside a laboratory -prepared sample container and marked with a unique
identifying sample ID and placed on ice in a sample cooler. Samples were analyzed for VOCs by
Environmental Protection Agency (EPA) Method 8260D.
2.2 October 2022
Three (3) previously sampled trees designated TC-8, TC-9, and TC-14 in August 2022 from Area 2
were selected for resampling in October 2022. The resampled trees included a Red Oak, Birch and Maple
with circumferences of 4.6, 4.0, and 4.3 feet, respectively.
Samples were collected on October 24, 2022. Samples were designated "TCRS" for Tree Core Resample
and include a numeral identifier (e.g. TCRS-1) Two (2) samples were collected from each tree, one from
the north -facing side [odd numerals] (TCRS-1, TCRS-3, and TCRS-5) and one from the south -facing side
[even numerals] (TCRS-2, TCRS-4, and TCRS-6) [Figure 4].
Samples were collected utilizing the same methods performed in August 2022 except a minimum of thirty
(30) grams of xylem was collected from each sample location. A total of six (6) samples were collected.
Each sample was marked with a unique identifying sample ID and placed on ice in a sample cooler.
Samples were analyzed for DX by EPA Method 8270E (SIM).

2.3 May 2023
Personnel from BLE walked Area 1 on May 10, 2023. Three (3) different grass species (Kentucky
Bluegrass, Riverbank Wild Rye, and Bushy Bluestein) and four (4) different tree species (Sycamore,
Hickory, Maple, and Birch) were selected for sampling (Figure 5). This event included sampling of grassy
foliage and tree sap. Grass sampling locations are shown as G-1 through G-3 on Figure 5. Tree sap
sampling locations are shown as TS-1 through TS-4 on Figure 5.
Grassy foliage samples were collected by removing grass growing along the riverbank. The grasses were
rinsed in a bucket of distilled water to remove soil from the root system. Roots were separated from the
foliage (culm [stems] and blades [leaves]) and each sampled separately. Grass leaf samples were designated
"GL" and grass root samples were designated "GR."
Two different field sample storage methods were utilized for the grass samples. Each root and foliage
sample was split between a laboratory -prepared container (jar) and a food -grade vacuum sealed bag. Grass
samples placed in jars were designated with an "A" suffix and grass samples placed in vacuum sealed bags
were designated with an `B" suffix. A total of twelve (12) grass samples were collected for analysis.
Tree sap samples were collected by boring a '/2-inch diameter by 4-inch deep hole into each tree
approximately 1-foot above the ground surface. A one-half ('/z)-inch outer diameter section of high density
polyethylene (HDPE) tubing was inserted into each hole and the open end was secured to a laboratory -
prepared sample container. Tree sap was allowed to flow for ten (10) days prior to collection. An
insufficient volume of sap was obtained from individual trees for analysis so the four (4) tree sap samples
were combined to form a single composite sample designed "TS-COMP."
Each grass and sap sample was marked with a unique identifying sample ID and placed on ice in a sample
cooler. Samples were analyzed for DX by EPA Method 8270E (SIM).

3.0 RESULTS
3.1 August 2022
The results of the August 2022 laboratory analyses are summarized on Table 1 and the laboratory analytical
data is included in Appendix A.
Concentrations of acetone, chloromethane, and styrene were detected in the samples. The laboratory detection
limit for DX and the other target VOCs exceeded the concentrations expected to be found in the samples,
requiring an alternate testing method for fixture analyses. The laboratory determined that fixture analyses should
focus on detection of DX only due to the low level of concentrations of other target VOCs present in the
groundwater at the landfill and due to the technical limitations of EPA Method 8260D.
3.2 October 2022
The results of the October 2022 laboratory analyses are summarized on Table 2 and the laboratory analytical
data is included in Appendix B.
DX was not detected above the laboratory detection limit in any of the six (6) samples collected in October
2022 utilizing EPA Method 8270E. The detection limit still exceeded the concentrations expected to be found
in the samples, requiring an alternative sample media and/or alternative sampling techniques.
3.3 May 2023
The results of the May 2023 laboratory analyses are summarized on Table 3 and the laboratory analytical
data is included in Appendix C.
DX was not detected in any of the twelve (12) grass samples collected in May 2023. A DX concentration
of 0.99J µg/1 was detected in the composite tree sap sample.
4.0 CONCLUSIONS AND RECOMMENDATIONS
The mass of sample material (solids) required for analysis led to elevated detection limits for the solid samples
collected and analyzed in August 2022. We conclude that the elevated detection limits masked the presence
of the target VOCs in the solid samples.
Alternate analytical methods utilized in the October 2022 sampling event also resulted in elevated detection
limits for the solid samples. We conclude that the elevated detection limits masked the presence of DX in the
solid samples.
Alternate sampling techniques (vacuum sealing) and alternate sample media (grass) collected in the May 2023
sampling event also resulted in elevated detection limits for the solid samples. We conclude that the elevated
detection limits masked the presence of DX in the solid samples.
Collection and analysis of tree sap in May 2023 demonstrated that concentrations of DX were present in the
sap. We conclude that the data indicates that the native flora are sequestering the DX and therefore
demonstrates that phytoremediation is a viable remedy for the VOC impacts to groundwater at the site.

We recommend that the facility proceed directly with Phase II and Phase III of the phytoremediation plan
pathway in general accordance with the SWS approved CAER.
Phase H will include a notification of selection of remedy in accordance with the solid waste rules. We
anticipate the selection of remedy will be submitted to the SWS on or before October 31, 2023. Phase III
will include submittal of a CAP addendum which may include: 1) preparation of design plans; 2)
preparation of bid packages and contractor selection; 3) procurement of selected flora; 4) the installation of
flora and irrigation; and 5) ongoing monitoring and maintenance (inspection, testing, and normal
horticultural practices). We anticipate the CAP addendum will be submitted to the SWS on or before May
31, 2024.

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

Coliform Colilert-18.
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.
This report supersedes all previous versions of the same lot number.
VOCs by GUMS
Insufficient sample volume was provided to perform matrix spike/matrix spike duplicate (MS/MSD) for
analytical batch51102, 50749, 50637, 50499, and 50513. An LCS/LCSD was run in lieu of an MS/MSD.
Surrogate recovery for the following sample was outside the upper control limit: XH05024-025, XH05024-
026, XH05024-030. This sample did not contain any target analytes; therefore, re -extraction and/or re-
analysis was not performed.
The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for analytical
batch 50637 exceeded acceptance criteria for Vinyl Chloride. These analytes were biased high and were
not detected in the samples affected.
Due to the large number of spiked analytes, there is a high probability that one or more analytes will
recover outside acceptance limits. The laboratory's SOP allows for 10% of analytes to recover marginally
outside criteria. The following analytes recovered marginally outside LCS/LCSD criteria: Acetone (143%).
Surrogate recovery for the following sample(s) was outside the upper control limit: XH05024-048. This
sample did not contain any target analytes; therefore, re -extraction and/or re -analysis was not performed.

Lot Number: XJ25061
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.
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.
1,4-Dioxane
Insufficient sample volume was provided to perform matrix spike/matrix spike duplicate (MS/MSD) for
prep batch 58957. An LCS/LCSD was run in lieu of an MS/MSD.
Due to the matrix, the initial sample amount used for the following sample deviated from the standard
procedure: XJ25061-003, XJ25061-004, XJ25061-005, XJ25061-006. The LOQ has been adjusted
accordingly.
The following samples were diluted due to the nature of the sample matrix: XJ25061-001, XJ25061-002,
XJ25061-003, XJ25061-004, XJ25061-005, XJ25061-006. The LOQ has been elevated to reflect the
dilution.
Surrogate recovery for the MB, LCS and the following sample was outside the upper control limit:
XJ25061-001, XJ25061-002, XJ25061-003, XJ25061-004, XJ25061-005, XJ25061-006. This samples did
not contain any target analytes; therefore, re -extraction and/or re -analysis was not performed.

Lot Number: YE19047
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

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.
SVOCs by GC/MS
Due to the matrix, the initial sample amount used for the following sample deviated from the standard
procedure: YE19047-002, YE19047-003, YE19047-004, YE19047-005, YE19047-006, YE19047-007,
YE19047-008, YE19047-009, YE19047-010, YE19047-011, YE19047-012, YE19047-013. The LOQ has
been adjusted accordingly.
Due to the matrix, the following samples could not be concentrated to the final method required volume:
YE19047-010, YE19047-011. The LOQs are elevated proportionately.
Due to insufficient sample received, the initial sample amount used for the following sample(s) deviated
from the standard procedure:YE19047-001. The LOQ has been adjusted accordingly.
Insufficient sample volume was provided to perform matrix spike/matrix spike duplicate (MS/MSD) for
prep batch 76230. An LCS/LCSD was run in lieu of an MS/MSD.
The following sample was diluted due to appearance or color: YE19047-001 and YE19047-002. The
LOQ has been elevated to reflect the dilution.
Surrogate recovery for the MB/LCS/LCSD associated to the following sample(s) was outside the upper
control limit: YE19047-002, YE19047-003, YE19047-004, YE19047-005, YE19047-006, YE19047-007,
YE19047-008, YE19047-009, YE19047-010, YE19047-011, YE19047-012, YE19047-013. Sample
surrogates passed and did not contain any target analytes; therefore, re -extraction and/or re -analysis was
not performed.
