1.0 Introduction

1.1 Site Information

The Columbus County Landfill site is located approximately 4.5 miles to the southwest
of the Town of Whiteville in Columbus County, North Carolina. The site is bordered to
the west by Spring Branch and to the northeast by Deep Branch. The site is occupied by
a closed solid waste landfill, a transfer station for solid waste, an office trailer, a truck
weigh scale and associated scale house, and two maintenance buildings. With the
exception of one maintenance building, these structures are located on the northwestern
portion of the site and are currently in use. One maintenance building, no longer in use,
is located near the northeastern corner of the site. When the landfill was in use, the office
and maintenance operations were located in this area.

Surrounding properties within 1,500 feet of the site are currently either undeveloped or
are being used for farming and residential purposes. Land use south of the site is mostly
farmland with a few wooded areas and residential properties. Land use west of the site is
mostly farmland with wooded areas and residential properties. Land use north of the site
is mostly wooded areas with a few residential properties and farmland. Land use east of
the site is mostly wooded areas and residential properties with a few areas of farmland.
The area of Columbus County where the site is located is not zoned.

1.2 Site Geology

The Geologic Map of North Carolina (1985) describes the site as being located in the
Coastal Plain physiographic province of North Carolina. More specifically, the map
indicates that sediments in the area of the Columbus County Landfill are classified as
being in the Yorktown Formation. Sediments of the Yorktown Formation are
fossiliferous clay with varying amounts of fine-grained sand, bluish gray, with shell
material concentrated in lenses.
Columbus County MSWLF Water Quality Monitoring Report
April 2016 Page 2

Soils encountered during prior assessment activities at the site consisted of fine sand with
varying amounts of silt from land surface to approximately 8.5 feet below land surface.
Sandy clay was encountered from approximately 8.5 to 18.0 feet below ground surface.
Below this sandy clay zone, silty sand soil was present.

1.3 Site Hydrogeology

Groundwater flow at the site has been determined to be directly north, toward Deep
Branch. The groundwater gradient across the site is approximately 0.0092 ft/ft. An
estimate of the hydraulic conductivity across the site was determined by Trigon
Engineering and presented in an August 12, 1997 report entitled “Semi-Annual
Groundwater Sampling Data, Columbus County Landfill, Columbus County, North
Carolina”. The estimated hydraulic conductivity at the site ranges from 0.011 ft/day to
0.97 ft/day. This translates to a groundwater flow rate in the shallow saprolite from 0.001
ft/day to 0.388 ft/day. The average hydraulic conductivity, gradients, total porosity, and
transmissivity values for the site are provided on Table 5.

A review of water quality data over the past several years indicates the presence of
several volatile organic compounds. These compounds have included benzene,
chlorobenzene, and 1,4-dichlorobenzene. These compounds are generally reported in
low concentrations in MW-11 (Figure 1). A review of historical water quality data from
the monitoring wells at the landfill indicates the concentrations of volatile organic
compounds have decreased over time and now only benzene and 1,4-dichlorobenzene
slightly exceed the NC 2L Groundwater Standards.

Columbus County MSWLF Water Quality Monitoring Report
April 2016 Page 3

2.0 Water Quality Monitoring Program

The water quality monitoring network at the closed Columbus County Landfill is evaluated on a
semi-annual basis. The location of the groundwater and surface water samples collected during
the semi-annual monitoring events is shown on the attached Figure 1.

2.1 Groundwater Monitoring Network
The existing monitoring well network consists of MW-1A (upgradient), MW-2A, MW-
3A, MW-5A, MW-7, MW-11, MW-12, CD-4, and CD-4D. Several of these wells appear
to be located immediately adjacent to buried waste. This may result in non-representative
groundwater samples as landfill gas and leachate may impact groundwater quality in the
immediate vicinity of the waste.

2.2 Surface Water Monitoring Network
In addition to the on-site groundwater monitoring wells, two surface water samples are
collected from Spring Branch, which flows along the western border of the closed
landfill. The samples will be designated US-1 (upstream) and DS-1 (downstream). The
location for the surface water samples is shown on the attached site map.

Columbus County MSWLF Water Quality Monitoring Report
April 2016 Page 4

3.0 Water Quality Sample Collection

Samples of groundwater and surface water were collected in accordance with the NC Solid Waste
Section Guidelines for Groundwater, Soil, and Surface Water Sampling Guidance Document,
2008. A brief description of the sample collection procedure is provided below.

3.1 Field Sample Procedures

Prior to groundwater sampling, water levels were obtained from each well using an
electric water level meter capable of measuring the depth to water to the nearest 0.01 feet.
This information was later used to determine the elevation of the water table in each
monitoring well relative to surveyed datum (Table 3). The depth to water in each well
was also used to determine the volume of standing water in the well casing. This
information allowed for the purging of a minimum of three casing volumes from each
well prior to sample collection to assure a fresh groundwater sample was collected. New
disposable laboratory gloves were worn by sampling personnel and each well was purged
and sampled with a new disposable bailer which was discarded after use.

After the monitoring wells had been allowed to recover from purging, samples are
collected in the following order:

 Volatile organic compounds
 Inorganic compounds
 Field Parameters (pH, Conductivity, Temperature)

The samples are collected directly in the laboratory-supplied containers which are pre-
filled with the appropriate preservative. No filtering of the samples is performed prior to
collection. After collection, the samples are placed in a cooler on ice for overnight
shipment to the analytical laboratory.

Columbus County MSWLF Water Quality Monitoring Report
April 2016 Page 5

Surface water samples are collected directly into the laboratory-supplied containers as
grab samples. Sampling personnel wear new disposable laboratory gloves for each
surface water sample collected. As with the groundwater samples, these samples are
stored in a cooler on ice prior to overnight delivery to the analytical laboratory.

3.2 Field Quality Assurance

One trip blank sample was prepared by the analytical laboratory and accompanied the
sample shipment until receipt back at the laboratory. The trip blank sample was analyzed
for volatile organic compounds only. Temperature blanks are also provided with the
sample shipments to assure the proper temperature is maintained until delivery to the
analytical laboratory.

3.3 Sample Delivery/Chain of Custody

All groundwater and surface water samples are stored in coolers on ice immediately after
collection. Individual sample containers for each well or surface water sample are placed
in separate zip lock plastic bags to reduce the potential for cross contamination. Chain-
of-Custody control documents are prepared and shipped with each cooler. Custody seals
are also used for each cooler to maintain sample integrity until delivery to the analytical
laboratory. The sample coolers are shipped via Federal Express for next morning
delivery to the analytical laboratory.

Columbus County MSWLF Water Quality Monitoring Report
April 2016 Page 6

4.0 Laboratory Analysis

The samples were analyzed for parameters specified by the NC Solid Waste Section for
Detection Monitoring at permitted solid waste facilities. The standard Detection Monitoring
Program for groundwater and surface water samples consists of the Appendix I parameters. The
Appendix I analysis consists of volatile organic compounds by EPA Method 8260B and
inorganic compounds by EPA Methods 6010C/6020A.

The laboratory performing the water quality analysis is Environmental Conservation
Laboratories, Inc. (ENCO) of Cary, North Carolina, which is a NC Certified Laboratory.
Internal quality control samples, including matrix spikes/matrix spike duplicates, are performed
by ENCO for each set of samples. The ENCO laboratory report, including internal quality
control samples, is provided with this report in Appendix A.

Columbus County MSWLF Water Quality Monitoring Report
April 2016 Page 7

5.0 Hydrogeological Conditions

The depth to groundwater was measured in the nine compliance monitoring wells during the
April 18, 2016 monitoring event. The groundwater elevations were calculated relative to the
surveyed measuring point (top of casing) for each monitoring well. The groundwater elevations
are summarized on Table 3 and the potentiometric surface of the shallow water table is shown on
Figure 1.

The general direction of groundwater flow, based on the water level information collected during
this monitoring event, is also shown on Figure 1. Groundwater flow direction is generally to the
north, toward Spring Branch.

Based on the results of prior hydrologic tests conducted at the site, the groundwater flow rate in
the shallow saprolite ranges from 0.001 ft/day to 0.388 ft/day. The average hydraulic
conductivity and transmissivity values for the site are provided on Table 5.

The vertical component of groundwater flow is determined from an evaluation of groundwater
elevations observed in nested well pairs. The one nested well pair at the site was evaluated for
vertical groundwater flow at the site. The vertical groundwater gradient was calculated from the
elevations determined from monitoring wells CD-4/CD-4D during the April 18, 2016 monitoring
event. The vertical component of groundwater flow in this well nest is 0.076 ft/ft downward.

6.0 Laboratory Analytical Results

Final laboratory analytical results for the samples collected on April 14, 2016 were received
from the analytical laboratory on April 28, 2016. A summary of the analytical results are
provided on Table 1 (groundwater), Table 2 (surface water), and Table 3 (field parameters).

6.1 Groundwater Analytical Results

Only two volatile organic compounds (VOC) were detected at a concentration equaling
or exceeding the NC 2L Groundwater Standard in any of the nine monitoring wells. The
compound benzene was reported at a concentration of 3.0 ug/l in monitoring well MW-
11, which slightly exceeds the 2L Groundwater Standard of 1.0 ug/l. The compound 1,4-
dichlorobenzene was reported at a concentration of 6.1 ug/l, also in monitoring well MW-
11, which slightly exceeds the 2L Groundwater Standard of 6.0 ug/l.

The inorganic analyses reported concentrations of arsenic in three monitoring wells
above the established 2L Groundwater Standard of 10 ug/l: MW-3A – 135 ug/l; MW-7 –
17.2 ug/l; and MW-11 – 10.6 ug/l. The inorganic compound chromium was reported in
monitoring well CD-4 at a concentration of 10.3 ug/l, which is slightly above the
established 2L Groundwater Standard of 10 ug/l.

No other VOC or inorganic compounds were reported in any of the monitoring wells at
or above the established NC 2L Groundwater Standards.

6.2 Surface Water Analytical Results

No VOCs were detected at a concentration equaling or exceeding the laboratory method
reporting limit or NC 2B Surface Water Standards in either of the two surface water
samples. No inorganic compounds were detected in the surface water samples above the
established 2B Surface Water Standards.

Columbus County MSWLF Water Quality Monitoring Report
April 2016 Page 9

6.3 Quality Control Sample

One trip blank was submitted and analyzed for quality assurance purposes. No VOCs
were detected at a concentration equaling or exceeding laboratory quantitation limits in
the trip blank.

Columbus County MSWLF Water Quality Monitoring Report
April 2016 Page 10

7.0 Conclusions

The results of this monitoring event report only minor variants from the established 2L
Groundwater Standards. A historical review of the groundwater data for the site indicates
a decreasing trend for the observed contaminants. Based on the results of this water
quality monitoring event, the closed Columbus County Landfill will remain in Detection
Monitoring in accordance with Title 15A NACA 13B .0601. The 2016 fall semi-annual
water quality monitoring event is tentatively scheduled for October/November 2016.

Attachments to this report include tables summarizing the groundwater and surface water
analytical results (Tables 1 & 2), field parameters collected during the monitoring event
(Table 3), well construction information (Table 4), and hydrologic test results (Table 5).
A copy of the laboratory analytical report in pdf and EDD formats is also included with
this report in Appendix A.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
