Dear Ms. Drummond:
Bunnell-Lammons Engineering, Inc. (BLE) is pleased to submit this report on behalf of Buncombe County.
The purpose of the work was to convert an existing piezometer (B-620) to a groundwater monitoring well
(MW-18) in accordance with North Carolina Division of Waste Management (DWM) - Solid Waste Section
(SWS) approved plans. Included herein is a brief description of the background project information, the

Report of Piezometer to Groundwater Monitoring Well Conversion: B-620 to MW-18 BLE Project No. J21-9378-26C
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
6 and a CDLF consisting of Phase 1 through Phase 6. Currently Cell 6 of the MSWLF and Phase 6 of the
CDLF are the active waste units. MSWLF Cell 7 has been permitted for construction and MSWLF Cells 8
through 10 are planned (but not permitted) for future expansion (Figure 2).
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.
The existing groundwater monitoring network for the Buncombe County Landfill consists of two (2)
upgradient (background) wells (MW-1 and MW-1D) and twenty-five (25) downgradient (compliance) wells
(MW-2, MW-2D, MW-3R, MW-4, MW-4D, MW-5, MW-5D, MW-6, MW-7, MW-8, MW-8D, MW-10,
MW-10D, MW-11, MW-11D, MW-12, MW-12D, MW-13, MW-13D, MW-14, MW-14D, MW-15, MW-
15D, MW-17R, and MW-17DR). Wells MW-17 and MW-17D were abandoned September 14, 2020 and
replaced by MW-17R and MW-17DR respectively.
In July 2021, Buncombe County initiated a voluntary assessment of the compliance issues related to the
detected concentrations of vinyl chloride in MW-15 and MW-15D (October 2020) and 1,2-dichloroethane
and vinyl chloride in MW-15D (April 2021). Buncombe County requested that BLE and Pace provide support
for the assessment activities. It was observed that the MW-15/MW-15D well pair was installed in very close
proximity to the waste limits, not installed at a location typical of a compliance boundary, and therefore did
not provide representative samples. We presumed that any impacts to groundwater and compliance issues (as
a result thereof) were an artifact of the close proximity of the well pair to the waste.
BLE submitted a report titled Report of Groundwater Compliance Assessment and Plan to Replace MW-
151MW-15D Well Pair dated July 28, 2021 (FID 1595066) to the SWS. The reported requested that
piezometer B-620 be converted to groundwater monitoring well designated MW-18 and that the new well
replace the MW-15/MW-15D well pair as a compliance point for the CDLF. The SWS approved the request
on August 3, 2021 (FID 1595460). This report documents the conversion of B-620 to MW-18.
PXI=.YK1]9we] DR] 11:Ai/[yxyiIH;70117:7U1I4E
Buncombe County located an existing piezometer designated B-620 which is present about 200 feet down
slope from the subject MW-15/ MW-15D well pair (Figure 2). Piezometer B-620 was installed in 2008 as
part of a design hydrogeologic investigation for the CDLF waste unit and was documented in a report by
CDM. The boring log for B-620 is included in Appendix A.
Piezometer B-620 was installed in bedrock and the wellhead was accessible and in good condition. Existing
surface completion included a 4" x 4" x 5' protective steel cover and 2' x 2' concrete pad. BLE made the
following modifications to the piezometer for compliance with monitoring well standards in the WQMP:
added a vent hole in the PVC casing near the top of the well, added a weep hole near the base of the outer
protective steel cover, added pea gravel inside of the outer protective steel cover, added a survey pin in the
concrete pad, and added an identification placard affixed to the protective steel cover with its new

corresponding well number (MW-18). Additionally, approximately 4 inches of PVC stick-up were
removed to allow the protective steel casing to properly close. Photographic documentation of the
conversion is included in Appendix B.
The location and elevation for MW-18 were surveyed on September 24, 2021 by a North Carolina registered
land surveyor (Ed Holmes & Associates Land Surveyors) retained by Buncombe County. A signed and sealed
certification for the survey was not provided by the surveyor and therefore not included herein.
Well completion information published by CDM and survey data from Ed Holmes & Associates was used to
populate Table 1 and to prepare a new boring log for MW-18 (Appendix A). The SWS approved sampling
matrix is included for reference (Table 2).
Development of groundwater monitoring wells is required in the WQMP. BLE performed development of
MW-18 by surging and pumping to remove the fine particles from the sand pack around the well screen. The
monitoring well was developed until pH and specific conductivity reached equilibrium. Turbidity values
decreased from greater than 2000 NTU to 20.7 NTU after development. A development log is included in
Appendix C.
3.0 SUMMARY
One piezometer (B-620) was converted to a groundwater monitoring well (MW-18) as approved by the SWS.
The piezometer has been converted and developed in accordance with the WQMP. Groundwater monitoring
well MW-18 has replaced the MW-151 MW-15D well pair as a compliance point for the CDLF as shown on
Table 2 and Figure 2.
4.0 QUALIFICATIONS OF REPORT
The activities and evaluative approaches used in this scope of work are consistent with those normally
employed in hydrogeological and environmental assessments of this type. Our evaluation of site conditions
has been based on our understanding of the site and project information and the data provided to BLE.
This report has been prepared on behalf of and exclusively for the use of Buncombe County, North Carolina.
This report and the findings contained herein shall not, in whole or in part, be used or relied upon by any other
party (excluding the SWS) without BLE's prior written consent.
5.0 CLOSING
We appreciate the opportunity to work with Buncombe County on this project. Please contact us at (864) 288-
1265 if you have any questions or comments.

- 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 1 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
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.
