1.0 INTRODUCTION
The Bladen County Construction and Demolition (C&D) Landfill, currently operating under Solid
Waste Permit # 09-05 (C&D) and 15A NCAC 13B.0544, is required to perform semi-annual
groundwater monitoring. This report presents the results for the sampling event reportedly
performed on September 21, 2016, in compliance with NC Solid Waste Regulations.

The groundwater monitoring network for the C&D landfill includes seven groundwater
monitoring wells. As specified in rule 15A NCAC 13B .0544 (j) and the November 5, 2014
Groundwater, Surface Water, Soil, Sediment, and Landfill Gas Electronic Document Submittal
Memo1, this report includes a field procedure summary, laboratory analyses, results summary
tables and Solid Waste Section (SWS) Environmental Monitoring Report Form for the C&D site.
2.0 SITE GEOLOGY
The Bladen Co. landfill is located off Highway 87 just east of Elizabethtown in the Coastal Plain
physiographic province. According to the Geologic Map of North Carolina (1985) this area is
underlain by the Black Creek Formation, which is characterized by gray to black lignitic clay
with thin beds of fine grained sands and thick lenses of cross-grained sand.
3.0 SAMPLING LOCATIONS
The sampling event, reportedly performed by Environment 1, Incorporated (Greenville, NC)
personnel on September 21, 2016, involved collecting samples from seven groundwater wells
(MW-1, MW-2, MW-3, MW-4, MW-5, MW-5A and MW-6), shown in Figure 1. MW-1 serves as the
upgradient, background well for this site.
4.0 SAMPLING PROCEDURES
Reported sampling methods followed the protocol outlined in the North Carolina Water Quality
Monitoring Guidance Document for Solid Waste Facilities (Department of Environmental Quality,
(DEQ), Division of Waste Management (DWM)). The depth to water in each well was gauged
prior to purging and sampling. Field measurements for pH, specific conductivity and
temperature were recorded at each monitoring location. Water table elevations are included in
Table 1.

Samples were reportedly collected by Environment 1, Inc. personnel and placed in laboratory
prepared containers for the specified analytical procedures using laboratory cleaned Teflon
bailers. Groundwater samples were properly preserved, placed on ice and transported to the
laboratory facility (Environment 1, Inc.), within the specified holding times for each analysis.

Section, November 5, 2014.

5.0 FIELD AND LABORATORY RESULTS
5.1 Field Parameter Results
Temperature, pH and specific conductance were measured in the field at the time of
sampling. The field parameter results are summarized in Table 2 and have remained
consistent with previously reported sampling events.
5.2 Laboratory Results
Samples were transported to the laboratory facility under proper chain of custody and
analyzed at the specified DWM Solid Waste Quantitation Limits (SWSLs) for Appendix I
parameters with the additional C&D required constituents. The laboratory report is
included as Appendix A.

Table 3 presents the detected constituents with their Method Detection Limit (MDL),
SWSL 2L Standard and Federal Maximum Contamination Limit (MCL). Constituents
detected between the MDL and the SWSL are identified by the laboratory as non-
quantifiable values, denoted as “J” values.
5.2.1 Inorganic Constituent Results
Arsenic (MW-1), iron (MW-1, MW-2, MW-3, MW-4, MW-5, MW-5A and MW-6) and
manganese (MW-1, MW-2, MW-4, MW-5, MW-5A and MW-6) were detected above
their 2L Standards this event. These constituents are naturally occurring in soils
in this area of North Carolina and are consistent with historic detections at this
site.

The indicator total alkalinity was reported as a quantifiable value, above the MDL,
in MW-2, MW-3, MW-4, MW-5A and MW-6; however no standard has been
established for this constituent.
5.2.2 Organic Constituent Results
No organic constituents were reported above their 2L Standards in samples
collected for this event. Tetrahydrofuran was reported detected, above the MDL,
in MW-5; however, no regulatory standards have been established, to date, for
this parameter.
6.0 GROUNDWATER CHARACTERIZATION
A potentiometric map (Figure 1) for the uppermost aquifer, was prepared from the
groundwater elevation data for this sampling event. The data indicates that groundwater in the

Bladen County C&D Landfill September 2016 Groundwater Monitoring Report
November 2016 Page 3
C&D area is flowing generally to the north. Hydraulic conductivity data is not available for these
wells so groundwater velocities could not be calculated.
7.0 CONCLUSIONS
Reported inorganic detections in groundwater samples are attributed to natural deposit
erosion. These inorganic constituents are naturally occurring in this area of North Carolina and
are likely due to suspended solids in the samples.

The next groundwater monitoring event is scheduled for March 2017; following receipt of
laboratory data a report will be prepared and submitted to NCDEQ and Bladen County.
