Subject: August 2016 Semi-Annual Sampling Report
Cumberland County Subtitle D Landfill
Facility Permit No. 2601-MSWLF-1997
Dear Mr. Lane:
CDM Smith Inc. (CDM Smith), on behalf of Cumberland County (County), is submitting an electronic copy
of the August 2016 semi-annual sampling event report. This letter report presents the results of the
semi-annual sampling event that was recently completed at the Cumberland County Subtitle D Landfill
and constitutes the second semi-annual sampling event for 2016. The current groundwater monitoring
network consists of the following wells: MW-F, -I, -J, and background well -E Rep. Surface water sample
locations include SW-4, -5, and -6, which also serve as monitoring locations for the closed Ann Street
Landfill. Field activities and sampling results are discussed below.
Field Activities
Groundwater and surface water samples from the Cumberland County Subtitle D Landfill were collected
on August 25-26, 2016. The groundwater samples were collected by use of a peristaltic pump using
low-flow sampling techniques with the exception of samples collected from MW-E Rep. Samples were
collected from MW-E Rep by use of a disposable, laboratory decontaminated bailer. Monitoring well and
surface water sampling locations are presented on Figure 1. Well construction details for each
monitoring well are summarized 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 the potentiometric contours for this sampling
event as shown on Figure 1. Note that the groundwater elevation from the former background
monitoring well, Old MW-E, was used for the potentiometric surface interpretation. The groundwater
elevations and potentiometric contours were used to estimate groundwater velocities at each well as
presented in Table 3. After depth to groundwater was measured, water was purged from each well to
provide fresh formation water within the well water column prior to sampling. Each well volume and
surface water sample 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. The water quality parameters at the time of sampling are presented in Table 4.
Sampling Results
Environmental Conservation Laboratories, Inc. located in Cary, North Carolina, analyzed all samples for
the North Carolina Appendix I volatile organic compounds (VOCs) and metals. VOCs were analyzed using
U.S Environmental Protection Agency (EPA) Method 8260B and metals were analyzed using EPA
Methods 6010D and 6020B. In accordance with Solid Waste Section (SWS) guidelines the analytical
results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or
below SWS Limits (SWSLs). All monitoring wells and surface water locations for the Subtitle D Landfill
had detections of analytes above the laboratory specific MDL but below the SWSL. These detections
were qualified with “J” flags, which indicate an estimated concentration.
The following list indicates which analytes were detected above the laboratory MDL at each sampling
location. No “J” flag detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC
2L) Groundwater Quality Standard, Groundwater Protection Standard, or the 15A NCAC 02B Surface
Water Quality Standard for Class C Waters. A complete summary of all detected and estimated
concentrations for the March 2011 through August 2016 sampling events is presented in Table 5. A
temporary groundwater monitoring well (TW-1) and a temporary surface water sampling location (TSW-
1) were located within the Cells 6-8 expansion. TW-1 has been abandoned and TSW-1 is no longer
sampled; however the historical results are provided in Table 5. The laboratory analytical data reports
are provided in Appendix A.

“J” flags were not included in the previous list, but several sampling locations had “J” flag detections
that exceeded the standards. The “J” flag constituents above the standards along with their location are
listed below.
Cobalt: MW-I, SW-5, and -6
Copper: SW-4
Vanadium: MW-E Rep and -I
Quality assurance and quality control samples were analyzed for the August 2016 sampling event. A
duplicate sample, labeled DUP, was collected from MW-F and had analyte concentrations similar to the
primary sample. No analytes were detected above laboratory MDLs in the trip blank. Table 6 presents a
summary of all parameters detected during the August 2016 sampling event that exceeded the NC 2L or
Groundwater Protection Standards.
CDM Smith, on behalf of the County, submitted the results of an Alternative Source Demonstration
(ASD) for the site on November 8, 2016. The ASD was prepared in accordance with Solid Waste rule
.1633(c)(3), to demonstrate that select metals exceeding the NC 2L Groundwater Standards detected in
monitoring wells at the site are naturally occurring and not related to a release from the landfill. As part
of the ASD, in order to determine if turbidity was a contributing factor to total reported metals, filtered
samples were collected during the August 2016 sampling event and analyzed for dissolved metals.
Dissolved metal sample results are provided in Table 5. Based on qualitative and quantitative evaluation
of current and historic groundwater sampling data, the NC 2L metal exceedances were determined to be
indicative of naturally occurring background concentrations as opposed to a release from the landfill.
The County will continue with the semi-annual groundwater monitoring program. The next sampling
event will take place during the spring of 2017. If you have any questions or require further explanation,
do not hesitate to call me at (919) 325-3500 or by email at weispfenningam@cdmsmith.com.
