Subject: March 2023 Annual Groundwater Sampling Report
East Wake Landfill - Rigsbee Property
Facility Permit Number 9202-MSWLF-1981
Dear Ms. Drummond:
CDM Smith Inc. (CDM Smith), on behalf of Wake County (County), is submitting an electronic copy of the
March 2023 annual sampling event report for the East Wake Landfill - Rigsbee Property (Site). The
approved groundwater monitoring network consists of one background well (i.e., MW-01), and three
downgradient monitoring wells (i.e., MW-03, -04S, and -04D).
On May 3, 2022, the North Carolina Department of Environmental Quality's (NCDEQ) Solid Waste
Section (SWS) approved modifications of the Site's sampling plan. The frequency of groundwater
sampling was reduced from semi-annually to annually and monitoring wells MW-02 and -07 were
removed from the sampling program. MW-02 and -07 were abandoned on September 12, 2022, and an
abandonment report was submitted to the SWS on October 7, 2022. This letter report presents the
results of the first annual sampling event. Field activities and sampling results are discussed below.
Background
The Site is located on two parcels. One of the parcels as shown on Figure 1 is owned by Carolyn
Properties, LLC and contains approximately 27 acres of waste. This parcel is referred to as the J.T. Knott
property and is currently part of the NCDEQ's Special Remediation Branch's Pre -Regulatory Landfill
program. The background monitoring well for the portion of the landfill located on the James Ervin
Rigsbee (Rigsbee) property, MW-01, is located on this parcel along with a private airport and several
businesses.
The parcel owned by Mr. Rigsbee contains approximately 46 acres of waste located in two separate
areas as shown on Figure 1. This parcel borders the J.T. Knott property to the south and west. A large
portion of the parcel is used for cattle pasture and includes an explosive storage company and

associated storage and office trailers, a home with a detached garage and two barns, and a storage area
for abandoned automobiles. All monitoring wells for the Site, except for the background well, are
located on this parcel. This portion of the Site operated under Permit Number 92-02 until the two waste
disposal areas ceased operations in 1983 (Area C) and 1985 (Area D).
The two areas of waste located on the Rigsbee property are known as Areas C and D as shown on Figure
1. Groundwater assessment for Area C is being conducted under the supervision of the Special
Remediation Branch's Pre -Regulatory Landfill Unit after this area of waste was determined to be eligible
for the program in the fall of 2012. Beginning in 2012, the County voluntarily collected groundwater
samples semi-annually from the Area C monitoring wells (i.e., MW-5, -6, -8, -9, and -10). On September
13, 2018, the SWS approved the discontinuation of the groundwater monitoring of Area C, beginning
with the fall 2018 sampling event.
Field Activities
Groundwater samples were collected on March 30-31 and April 4, 2023, by use of disposable, laboratory
decontaminated bailers. Monitoring well sampling locations are presented on Figure 1. Well
construction details are provided in Table 1.
Groundwater elevations were measured at each well on March 30, 2023, prior to sampling and are
presented in Table 2. These groundwater elevations were used to construct potentiometric contours for
this sampling event and are presented on Figure 1. The groundwater elevations and potentiometric
contours were used to estimate the groundwater velocity at each well. Groundwater velocity values are
provided in Table 3.
After depth to groundwater was determined, three well volumes of water were removed from each well
prior to sampling to provide fresh formation water within the well water column. Each well volume was
measured for pH, conductivity, temperature, turbidity, dissolved oxygen, and oxidation-reduction
potential using a YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter.
Wells with elevated turbidity (i.e., greater than 10 Nephelometric Turbidity Units (NTUs)) were allowed
to stabilize prior to sample collection. The water quality parameters at the time of sampling are
presented in Table 2.
Alternate Source Demonstration
On August 17, 2020, CDM Smith submitted an Alternate Source Demonstration (ASD) for the Site on
behalf of the County. The purpose of the ASD was to demonstrate that metals exceeding the 15A NCAC
02L .0202 (NC 2L) Groundwater Standards or Interim Maximum Allowable Concentrations (IMACs) are
naturally occurring and not related to a release from the landfill. The ASD was prepared using analytical
data from the background monitoring well, MW-01, that was collected on a quarterly basis from January
2018 to February 2020 to develop upper tolerance limits (UTLs) for specific analytes that historically

exceeded their respective NC 2L Groundwater Standard or IMAC. Based on statistical analysis, a UTL of
2.82 parts per billion (ppb) was proposed for cobalt and a UTL of 2 ppb was proposed for vanadium. The
SWS approved these proposed UTLs on August 20, 2020.
On April 1, 2022, the SWS updated the NC 2L Groundwater Standards and IMACs. The updated NC 2L
Groundwater Standard for vanadium is 7 ppb, which is greater than the UTL. The NC 2L Groundwater
Standard for vanadium will be used instead of the UTL.
Sampling Results
Pace Analytical Services, LLC, located in West Columbia, South Carolina, analyzed the groundwater
samples for the North Carolina Appendix I volatile organic compounds and Appendix I metals. In a letter
dated May 29, 2018, the SWS stated that all groundwater and surface water samples collected from
landfills be analyzed for 1,4-dioxane after July 1, 2018. On June 26, 2019, the SWS approved the removal
of 1,4-dioxane from the sampling program for all monitoring wells, except for MW-03, -04S, and -4D,
due to two consecutive non -detect events (October 2018 and April 2019). Samples were collected from
the wells requiring the 1,4-dioxane analysis during the March 2023 annual sampling event and the
results are provided below.
The analytical results were reported to the laboratory specific method detection limit (MDL) and are
quantifiable at or below the laboratory limit of quantitation (LOQ). All monitoring wells for the Site had
detections of analytes above the MDL but below the LOQ that were qualified as estimated or "J" flags. In
samples collected from MW-03, -045, and -04D, barium detections had "D" flags, indicating that the
analyte was analyzed at a dilution greater than one.
The following list indicates the analytes detected above the LOQ at each sampling location. There were
no "J" flag detections above the standards. Underlined analytes exceeded the NC 2L Groundwater
Standard or UTL. A complete summary of all detected and estimated concentrations for the March 2023
sampling event is provided in Table 4. The laboratory analytical data report is provided in Appendix A.

An equipment blank, trip blank, and duplicate sample were analyzed for quality control. No analytes
were detected in the equipment or trip blanks above the MDLs. The duplicate sample, identified as DUP,
was collected from MW-03 and had similar analyte concentrations as those detected in MW-03, except
for estimated detections of lead and zinc in the parent sample below their respective NC 2L
Groundwater Standards that were not detected in the duplicate. Table 5 presents a summary of all
parameters detected during the March 2023 sampling event that exceeded the NC 2L Groundwater
Standards or UTLs.
Additional metals samples were collected from MW-03, -045, and -04D during the March 2023 sampling
event for the laboratory to filter and analyze due to elevated turbidity (i.e., greater than 10 NTUs). The
samples were collected to demonstrate that select metals exceeding the NC 2L Groundwater Standards
are naturally occurring and not related to a release from the landfill. However, dissolved metals were
not analyzed due to a laboratory error.
The County will continue annual sampling of the updated groundwater monitoring network for Area D
(i.e., MW-1, -3, -04S, and -04D). The concentration of 1,4-dioxane will continue to be monitored in
MW-03, -04S, and -04D. The next sampling event will be completed in the spring of 2024.
