Subject: April 2019 (Spring) Semi -Annual Groundwater Sampling Report
East Wake Landfill - Rigsbee Property
Facility Permit No. 9202-MSWLF-1981
Dear Ms. Drummond:
CDM Smith Inc., on behalf of Wake County (County), is submitting an electronic copy of the April 2019
semi-annual sampling event report for the East Wake Landfill - Rigsbee Property. This letter report
presents the results of the most recent semi-annual sampling event and constitutes the first semi-
annual sampling event for 2019. The approved groundwater monitoring network consists of one
background well (i.e. MW-01), and five downgradient monitoring wells (i.e. MW-02, -03, -04S, -04D,
and -07). Field activities and sampling results are discussed below.
Background
The East Wake Landfill (landfill) 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 North Carolina Department of
Environmental Quality's Inactive Hazardous Sites 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 landfill, with the exception of the
background well, are located on this parcel. This portion of the landfill 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 Inactive
Hazardous Sites Pre -Regulatory Landfill Unit after this area of waste was determined to be eligible for
the program in the fall of 2012.
Since 2012, the County has 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 Solid Waste Section
approved the discontinuation of the groundwater monitoring of Area C, beginning with the fall 2018
sampling event.
Field Activities
Groundwater samples from the landfill monitoring wells were collected on April 17, 2019. All samples
were collected 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 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 that had elevated turbidity were allowed to stabilize prior to sample
collection. The water quality parameters at the time of sampling are presented in Table 2.
Sampling Results
Shealy Environmental Services, Inc. located in West Columbia, South Carolina, analyzed the
groundwater samples for the North Carolina Appendix I volatile organic compounds, including 1,4-
dioxane, and Appendix I metals. 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 Landfill had detections of analytes above the MDL but below the
LOQs and were qualified as estimated or "J" flags. All detections of chromium had "B" flags, indicating
that the analyte was detected in the method blank.
The following list indicates the analytes detected above the LOQ at each sampling location. No "J" flag
detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater
Standard or Interim Maximum Allowable Concentrations (IMACs). A complete summary of all

An equipment blank, trip blank, and duplicate sample were analyzed for quality control. Acetone and
2-butanone were detected as estimated concentrations in the equipment blank below their respective
NC 2L Standards. No analytes were detected in the trip blank above the MDLs. The duplicate sample,

identified as DUP, was collected from MW-02 and had similar analyte concentrations as those
detected in MW-02, with the exception of an estimated detection of nickel in the parent sample
below its NC 2L Standard. Table 5 presents a summary of all parameters detected during the April
2019 sampling event that exceeded the NC 2L or IMAC Standards.
As part of an ongoing Alternate Source Demonstration for the landfill, filtered samples were collected
from all monitoring wells during the April 2019 sampling event due to elevated turbidity (i.e. greater
than 10 Nephelometric Turbidity Units). These samples were collected to demonstrate that select
metals exceeding the NC 2L or IMAC Standards are naturally occurring and not related to a release
from the landfill.
Total metals that exceeded the NC 2L or IMAC Standards in samples collected from the monitoring
wells were analyzed for dissolved metals to determine if turbidity was a contributing factor to the
total reported metals. The filtered samples collected from MW-02 and -03 were not analyzed for
dissolved metals since none of the unfiltered total metal results exceeded the standards. Below is a
summary of the dissolved metals exceedances. Wells with a "*' qualifier had a "J" flag detection for
that analyte.
Barium: MW-04D
Cobalt: MW-04S and -04D
Vanadium: MW-04S*
Dissolved metal sample results are provided in Table 4. Based on qualitative and quantitative
evaluation of current and historic groundwater sampling data, the NC 2L or IMAC Standard metal
exceedances from the April 2019 sampling event were determined to be indicative of naturally
occurring background concentrations as opposed to a release from the landfill.

Case Narrative
CDM Smith
Lot Number: UD20011
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.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved NELAC standards, the Shealy Environmental Services, Inc. ("Shealy") Quality
Assurance Management Plan (QAMP), standard operating procedures (SOPS), and Shealy policies. Any
exceptions to the NELAC standards, the QAMP, SOPS or policies are qualified on the results page or
discussed below.
VOA 8260D
The continuing calibration verification (CCV) associated with samples UD20011-001 (MW-01), UD20011-
002 (MW-02) , UD20011-003 (MW-03), UD20011-004 (MW-04S), UD20011-005 (MW-04D), UD20011-
006 (MW-07), and UD20011-007 (DUP) for acetone recovered above the upper control limit. The
samples associated with this CCV were non -detect for the affected analytes; therefore, the data has been
reported.
1,4-dioxane SIM 8260D
The following samples was received with air bubbles in the sample vial greater than 6mm: UD20011-003
(MW-03) and UD20011-009 (TRIP BLANK).
