Subject: September 2017 Semi-Annual Groundwater Sampling Report
Dare County C&D Landfill
Dare County, North Carolina
Facility Permit Number 2803-CDLF-1995
Dear Ms. Drummond:
CDM Smith Inc., on behalf of Dare County, is submitting an electronic copy of the September 2017
semi-annual groundwater sampling event report. This letter report presents the results of the most
recent semi-annual sampling event that was completed at the Dare County C&D Landfill and
constitutes the second semi-annual sampling event for 2017. The approved groundwater monitoring
network consists of 13 wells (i.e. MW-1 (background well), -2, -3, -8, -9, -10, -11, -12, -13, -14, -15, -16,
and -17) and three surface water sampling locations (i.e. SW-1, -2, and -3).
No samples were collected from monitoring well MW-8 due to damage observed by the sampling
team during the September 2017 sampling event. The damaged well will be evaluated and repaired or
replaced prior to the spring 2018 semi-annual sampling event. Monitoring well MW-9 was abandoned
and reinstalled prior to the September 2017 sampling event due to a damaged protective cover and
polyvinyl chloride (PVC) riser. Field activities, sampling and landfill gas monitoring results, and
abandonment and reinstallation activities for MW-9 are discussed below.
Field Activities
Groundwater and surface water samples from the Dare County C&D Landfill were collected on
September 21-22, 2017, by Environment One, Inc. (Environment One). Monitoring wells and surface
water sample locations are shown on Figure 1. Well construction details for the monitoring wells are
provided in Table 1.
Groundwater elevations were measured at each well prior to sampling using an electronic water level
indicator with an accuracy of 0.01 feet. These groundwater elevations as presented in Table 2 were

used to construct a potentiometric surface map for this sampling event. The potentiometric contours
are presented on Figure 1.
Each monitoring well was measured for pH, conductivity, temperature, turbidity, dissolved oxygen,
and oxidation-reduction potential (ORP) prior to sampling. The same water quality parameters were
measured at the surface water sample locations with the exception of ORP. The water quality
parameters at the time samples were collected are presented in Table 2. Due to damage, no samples
were collected from monitoring well MW-8. The well will be evaluated for repair or replacement prior
to the Spring 2018 sampling event.
Sampling Results
Environment One located in Greenville, North Carolina, analyzed the groundwater and surface water
samples for North Carolina Appendix I volatile organic compounds by U.S. Environmental Protection
Agency (EPA) Method 8260B, metals by EPA Methods 200.7, 200.8, and Standard Method (SM) 3111B,
mercury by EPA Method 245.1, alkalinity by SM 2320B, chloride and sulfate by SM 4500, and total
dissolved solids (TDS) by SM 2540C. In accordance with Solid Waste Section guidelines, the analytical
results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at
or below Solid Waste Section Limits (SWSLs). All monitoring wells and surface water sample locations
for the C&D Landfill had detections of analytes above the MDL but below SWSLs. These detections
were qualified with “J” flags, which indicate an estimated concentration.
The following list presents the analytes detected above the MDL at each sample 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 or Protective Value Surface
Water Quality Standard for Class C Waters. A complete summary of all detected and estimated
concentrations for the September 2017 sampling event and previous events is presented in Table 3.
Analytical results for TDS are provided in Table 2. The laboratory analytical report is provided in
Appendix A.

Equipment and trip blanks were analyzed for quality control. A duplicate sample was also collected for
quality control. No analytes were detected in the trip blank above the MDL. The equipment blank had
estimated detections of antimony, chromium, iron, and lead below their respective NC 2L or
Groundwater Protection Standards. The duplicate sample was collected from MW-3 and had similar
analyte concentrations as those detected in MW-3, with the exceptions of estimated detections of
antimony and zinc, and a detection of tetrahydrofuran in the duplicate sample.
As part of the planned Alternate Source Demonstration for the landfill, filtered metals samples were
collected from all monitoring wells during the September 2017 sampling event to demonstrate that
select metals exceeding the NC 2L or Groundwater Protection Standards are naturally occurring and
not related to a release from the landfill. Total metals that exceeded the NC 2L or Groundwater
Protection Standards or have a history of exceedances were analyzed for dissolved metals to
determine if turbidity was a contributing factor to total reported metals. Below is a summary of the
dissolved metal exceedances. Wells with a “*” qualifier were reported as “J” flag detections for that
analyte.
Arsenic: MW-17
Chromium: MW-11
Cobalt: MW-17*
Iron: MW-1, -2, -3, -9, -10, -12, -13, -14, -15, -16, and -17
Manganese: MW-1, -2, -3, -10, -11, -12, -13, -14, -15, -16, and -17
Vanadium: MW-9*, -10*, -12*, -14*, -15*, -16*, and -17*
Dissolved metal sample results are provided in Table 3. Based on qualitative and quantitative
evaluation of current and historic groundwater sampling data, the NC 2L or Groundwater Protection
Standard metal exceedances from the September 2017 sampling event were determined to be
indicative of naturally occurring background concentrations as opposed to a release from the landfill.
The semi-annual groundwater monitoring program will be continued by Dare County. The first semi-
annual sampling event for 2018 is tentatively scheduled for February.
Landfill Gas Monitoring
The approved landfill gas monitoring network consists of landfill gas probes M-1 through -12. Landfill
gas probe locations are shown on Figure 1. Site structures that are monitored on the property include
the scale house and the maintenance shop. Quarterly landfill gas monitoring of the C&D Landfill was
completed on August 18 and October 20, 2017, using a GEM 2000 Plus landfill gas analyzer. No
measurements were collected from M-4 during either event due to a damaged stopcock valve. A new
valve will be installed prior to the first quarterly monitoring event in 2018.

Methane was detected above the 5% lower explosive limit in M-12 during both monitoring events.
This landfill gas well is located next to a swampy area and is near the maintenance shop. No methane
was detected in the maintenance shop or any of the site structures. A cut-off trench was installed
near M-12 in 2015 to evaluate the source of methane in the well and for remediation purposes. The
methane detections in M-12 are likely related to the swampy area adjacent to the well as opposed to
a release from the landfill. Future detections will be evaluated.
No hydrogen sulfide was detected in any monitoring wells or site structures. Copies of the quarterly
landfill gas monitoring results along with the GEM 2000 Plus calibration information have been placed
in the landfill operating record and are provided in Appendix B.
Well Abandonment and Reinstallation
On August 9, 2017, monitoring well MW-9 was abandoned due to a damaged protective cover and
PVC riser. MW-9 was abandoned by over drilling to remove the existing well material. Once the
material was removed, the borehole was backfilled with a Portland cement and bentonite mixture. A
copy of the Well Abandonment Record is provided in Appendix C.
Once abandonment was complete, a new well was installed approximately 5 feet from the original
location. MW-9 was installed using hollow-stem auger drilling techniques to 15 feet below ground
surface. The well was constructed with five feet of 2-inch diameter PVC riser flush-threaded to ten
feet of 2-inch diameter 0.01-inch mill slotted PVC pre-packed screen. The borehole annulus was
backfilled with an additional sand filter to 1-foot above the screen. A bentonite annular seal was
installed two feet above the sand filter. The remainder of the borehole annulus was completed with a
Portland cement and bentonite mixture to land surface. The well was completed with an above-grade
4-inch steel protective cover and 3-foot by 3-foot concrete pad. Four protective bollards were
installed around the perimeter of the well to prevent future damage. The Well Construction Record
and the boring log are provided in Appendix C. Well construction details are provided in Table 1.
