ASSESSMENT MONITORING
GROUNDWATER AND SURFACE WATER
VANCE COUNTY MSW LANDFILL, PERMIT NO. 91-01
HENDERSON, NORTH CAROLINA

1.0 INTRODUCTION

Sherrill Environmental, Inc. (Sherrill) was retained by Vance County to perform
compliance monitoring for the Vance County Municipal Solid Waste Landfill (MSWLF)
Permit No. 91-01. This facility is located on North Carolina Highway 39, north of
Henderson (Figure 1).

The Vance County MSWLF has a Closed Landfill (1997) and a Pre-1991 Landfill.
Monitoring of the groundwater and surface water at the site is performed on a semiannual
basis in accordance with North Carolina regulations T15A:13B.1633 and .1634. The
Closed Landfill requires an assessment monitoring program. According to the 1994
groundwater monitoring plan for the Closed Landfill, groundwater samples are collected
from monitoring wells MW-5, MW-6, MW-7, and MW-8 and are analyzed for the
Appendix II list of constituents (40 CFR 258). In April 1999, two additional monitoring
wells, MW-6D and MW-9 were installed to monitoring side gradients of the Closed
Landfill. On August 11, 2004, a new upgradient background monitoring well (MW-10)
was installed to replace MW-5. In 2009, MW-6D was replaced with a deeper well MW-
6DR. These additional and replacement monitoring wells are also sampled for the
Appendix II list of constituents. Groundwater samples for the Pre-1991 Landfill are
collected from MW-1 and MW-2, and are analyzed for the eight RCRA metals and
Appendix I volatile organic compounds. Surface water at the site requires a detection
monitoring program. Surface water samples are collected from three stations along an
unnamed tributary of Crooked Creek (SW-1, SW-2 and SW-3) and are analyzed for the
Appendix I list of constituents (40 CFR 258).

Applicable water quality standards used for comparison of the analytical results are the
North Carolina Administrative Code (NCAC) 2L Groundwater Quality Standards (2L
Vance Co. MSWLF
8/2016 Monitoring
C:\Users\Jack\OneDrive\S E I\Vance Co\GW Monitoring\August 2016 RPT\RPT-8-16.docx
Standard), the NCAC 2B Surface Water Quality Standard (2B Standard) and the NC
SWS Groundwater Protection Standard.

2.0 INVESTIGATION

Sherrill perform the sampling on August 30, 2016. Groundwater table measurements
were obtained from the seven groundwater monitoring wells (MW-5, MW-6, MW-6DR,
MW-7, MW-8, MW-9 and MW-10) at the Closed Landfill and the two groundwater
monitoring wells (MW-1, and MW-2) at the Pre-1991 Landfill (Figure 2).
Environmental samples were collected on August 30, 2016 and analyzed in accordance
with the Vance County Transition Plan and the memorandum from the Solid Waste
Section dated October 27, 2006 and February 23, 2007 addressing New Guidelines for
Electronic Submittal of Environmental Data. The groundwater samples were placed in
laboratory-supplied glassware and transferred to a North Carolina Department of
Environment and Natural Resources (NCDENR) certified laboratory using standard,
chain-of-custody procedures. Field measurements of pH, specific conductivity and
temperature were performed for each groundwater and surface water sample.

3.0 GROUNDWATER TABLE
On August 30, 2016, groundwater table measurements were obtained from nine site
monitoring wells (Table 1). The depth to the groundwater from the ground surface
ranged from approximately 6 foot at MW-2 and MW-6DR, to 33 feet at MW-8. A map
of the groundwater table is presented in Figure 2. The direction of groundwater flow is
westward towards an unnamed tributary of Crooked Creek. The groundwater gradient
beneath the Closed Landfill ranged from 0.021 ft/ft to 0.063 ft/ft and averaged 0.050 ft/ft
(Table 2). The groundwater gradient along the western edge of the Pre-1991 Landfill
ranged from 0.036 ft/ft to 0.071 ft/ft. The increasing gradient near the tributary and the
shallow depth of groundwater indicate a likely discharge of groundwater to the creek.

The seepage velocities calculated for each monitoring well at the Closed Landfill are
presented in Table 2 and shown on Figure 3. The seepage velocities ranged from 0.23
ft/day to 0.57 ft/day and averaged 0.42 ft/day.

4.0 SPECIFIC CONDUCTIVITY AND pH
4.1 GROUNDWATER
Specific conductivity and pH measurements were obtained in the field for the
groundwater samples (Table 7). A pH of 6.5 to 8.5 is the acceptable range listed by the
2L Standard. The 2L Standard does not list a value for specific conductivity. Specific
conductivity values are shown at monitoring locations in Figure 4. The specific
conductivity measurement for groundwater sample from the background monitoring well,
MW-10, was 2,680 micro siemens per centimeter (uS/cm). Specific conductivity
measurements for groundwater samples from the Closed Landfill ranged from 2,360
uS/cm at monitoring well MW-9 to 4,670 uS/cm at MW-6DR. Specific conductivity
measurements for groundwater samples from the Pre-1991 Landfill were 2,490 uS/cm
and 2,470 uS/cm in the groundwater samples from MW-1 and MW-2, respectively.
The pH measurements for groundwater samples from the Closed Landfill ranged from
5.22 at MW-9 to 7.83 at MW-6. The pH measurements for groundwater samples from
the Pre-1991 Landfill were 5.63 at MW-1 and 5.56 at MW-2.
4.2 SURFACE WATER
Specific conductivity and pH measurements were obtained in the field for the surface
water samples (Table 7). The 2B Standard does not list a value for specific conductivity.
The specific conductivity measurement for the upstream surface water sample (SW-1)
was 163 uS/cm (Figure 4). The midstream surface water sample (SW-3) had a specific
conductivity of 216 uS/cm. The downstream surface water sample (SW-2) had a specific
conductivity of 209 uS/cm.
Vance Co. MSWLF

C:\Users\Jack\OneDrive\S E I\Vance Co\GW Monitoring\August 2016 RPT\RPT-8-16.docx
Measurements of pH were obtained in the field for the surface water samples (Table 7).
The pH range of 6.0 to 9.0 is listed by the 2B Standard. The pH measurement for the
upstream surface water sample (SW-1) was 7.42. The midstream surface water sample
(SW-3) had a pH of 7.14. The downstream surface water sample (SW-2) had a pH of
8.04.
5.0 ANALYTICAL RESULTS

5.1 CLOSED LANDFILL

The groundwater monitoring wells (MW-5, MW-6, MW-7 and MW-8) for the Closed
Landfill were installed in 1994. Groundwater monitoring wells MW-6D and MW-9 were
installed in April 2000. Background monitoring well MW-5 was replaced by MW-10 in
August 2004. Groundwater monitoring well MW-6D was replaced with a deeper well
MW-6DR in 2009. Analytical data from 2004 to present is compiled on summary tables
(Tables 3 and 4). The Enco Laboratory report is included in the Appendix.

5.1.1 Volatile Organic Compounds

A summary of volatile organic compounds detected in groundwater samples for the
Closed Landfill is presented in Table 3. Volatile organic compounds and their detected
concentrations that exceeded a standard are shown in Figure 5.

No volatile organic compounds were detected in the groundwater samples from the
upgradient monitoring well MW-10 or downgradient monitoring well MW-9.

Benzene and chlorobenzene were detected in the groundwater sample from MW-6 at
concentrations of 1.5 ug/L and 3.5 ug/L, respectively. The 2L Standard for benzene is 1
ug/L and chlorobenzene is 50 ug/L. 1,4-Dichlorobenzene was detected in a concentration
of 2.9 ug/L which is less than the 2L Standard of 6 ug/L. Volatile organic compounds
detected in the paired deeper well, MW-6DR, were benzene at 1.3 ug/L, vinyl chloride at
2.4 ug/L and 1,4-dichlorobenzene at 1.8 ug/L. The 2L Standard for vinyl chloride is 0.03
Vance Co. MSWLF
8/2016 Monitoring

ug/L. Benzene and vinyl chloride were the only volatile organic compound to exceed a
standard at the paired MW-6 monitoring wells.

Chlorobenzene and 1,4-dichlorobenzene were detected in the groundwater sample from
MW-7 at concentrations of 12 ug/L and 3.8 ug/L, respectively. These concentrations are
less than the 2L Standard.

The volatile organic compounds chlorobenzene, cis-1,2-dichloroethene, 1,4-
dichlorobenzene, tetrachloroethene, trichloroethene and vinyl chloride were detected in
the groundwater sample from MW-8. Compounds detected in concentrations that
exceeded groundwater standards were 1,4-dichlorobenzene at 6.8 ug/L, tetrachloroethene
at 7.1 ug/L, trichloroethene at 3.4 ug/L, and vinyl chloride at 2.9 ug/L. These compounds
have been detected in similar concentrations in previous groundwater samples from MW-
8. The compounds detected in the groundwater from MW-8 are typical of chlorinated
solvents and their breakdown products.

5.1.2 Semivolatile Organic Compounds

Sampling for semivolatile organic compounds was not required for the second portion of
2016 because no semivolatile organic compounds were detected by the Appendix II
sampling conducted in February 2016. Semivolatile organic compounds have not been
detected by previous monitoring programs.

5.1.3 Pesticides/Herbicides
Sampling for pesticides or herbicide compounds was not required for the second portion
of 2016 because no pesticides or herbicide compounds were detected by the Appendix II
sampling conducted in February 2016. No pesticide or herbicide compounds have been
detected since 2003.

5.1.4 Inorganic Constituents
A summary of inorganic constituents detected in groundwater samples for the Closed
Landfill is presented in Table 4. Inorganic constituents that exceeded a Standard for this
sampling event are shown in Figure 6.

Cobalt was the only metals detected above the required NC SWSLs in the groundwater
sample from the upgradient monitoring well MW-10. Cobalt is not listed by the 2L
Standard. Cobalt has a SWSL of 10 ug/L and a Groundwater Protection Standard of 2
ug/L. Cobalt was detected in the groundwater sample from MW-10 in a concentration of
18.9 ug/L.

Inorganic constituents detected above the required NC SWSLs in one or more of the
downgradient monitoring wells (MW-6, MW-6DR, MW-7, MW-8, and MW-9) were
barium, cobalt, copper and nickel. Of these inorganic constituents, barium and nickel
were detected in concentrations that exceeded the 2L Standards. Concentrations of
cobalt exceed the Groundwater Protection Standard of 2 ug/L.

Vance Co. MSWLF
8/2016 Monitoring
C:\Users\Jack\OneDrive\S E I\Vance Co\GW Monitoring\August 2016 RPT\RPT-8-16.docx
Barium was detected in concentrations that ranged from 270 ug/L at MW-7 to 1,500
ug/L at MW-6. Concentration of barium that exceeded the 2L Standard of 700 ug/L
were detected at MW-6 and MW-6DR.

Cobalt was detected above the Groundwater Protection Standard of 2 ug/L in four
downgradient monitoring wells and the upgradient monitoring well MW-10.
Concentrations of cobalt ranged from less than 10 ug/L at MW-6DR (deep) to 167 ug/L
at MW-6 (shallow). These detected concentrations of cobalt are consistent with previous
data. The suspected source of the cobalt is from factory scraps of blue dyed air filters
that were disposed in the landfill. Cobalt was detected in the upgradient well MW-10 in a
concentration of 18.9 ug/L.

Copper was detected above the NC SWSL of 10 ug/L in samples from MW-6, MW-7,
MW-8 and MW-9 in concentrations 152 ug/L, 72 ug/L, 14 ug/L and 63 ug/L,
respectively. The 2L Standard for copper is listed at 1,000 ug/L.

Nickel was detected above the NC SWSL of 50 ug/L in samples from MW-6, MW-6DR,
MW-8 and MW-9 in concentrations of 141 ug/L, 50.5 ug/L, 87 ug/L and 55 ug/L. The
2L Standard for nickel is listed at 100 ug/L.

In summary, barium and nickel were the only metals detected in the groundwater samples
associated with the Closed Landfill that exceeded 2L Standards. Cobalt exceeded the
Groundwater Protection Standard of 2 ug/L in four downgradient monitoring wells.
Cobalt was also detected in the upgradient well MW-10 in a concentration of 18.9 ug/L.
The metal concentrations detected by this monitoring event were generally consistent
with previous data.

5.2 PRE-1991 LANDFILL

A summary of the groundwater analysis for this monitoring program for the Pre-1991
Landfill is presented in Table 5. Monitoring wells MW-1 and MW-2 are located
downgradient and adjacent to the Pre-1991 Landfill. Groundwater samples were
collected from monitoring wells MW-1 and MW-2 and analyzed for the eight RCRA
metals and the Appendix I list of volatile organic compounds by GC/MS (SW-846 8260).

The detection of volatile organic compounds was limited to MW-1. Volatile organic
compounds detected above NC SWSLs were benzene at 1.4 ug/L, chlorobenzene at 4.4
ug/L and 1,4-dichlorobenzene at 2.3 ug/L. Of these compounds, only benzene was
present in a concentration that exceeded a 2L Standard. No volatile organic compounds
were detected in the groundwater sample from MW-2.

Barium and lead were the only RCRA metal detected above the NC SWSLs. Barium was
detected in concentrations of 195 ug/L at MW-1 and 190 ug/L at MW-2. The 2L
Standard for barium is 700 ug/L. Lead was detected at MW-1 in a concentration of 11.5
ug/L. The 2L Standard for lead is 15 ug/L.

5.3 SURFACE WATER

A summary of the surface water analysis for this monitoring program is presented in
Table 6. Surface water samples were collected from the three surface water sampling
stations (SW-1, SW-2, and SW-3). The samples were analyzed for the Appendix I list of
constituents. No volatile organic compounds were detected above NC SWSLs of the
SW-846 8260 method. No Appendix I metals were detected above the NC SWSLs.
These results are consistent with previous data.

6.0 SUMMARY

Volatile organic compounds detected above the 2L Standard were limited to MW-6,
MW-6DR and MW-8. The volatile organic compounds with concentrations that
exceeded the 2L Standard were benzene, tetrachoroethene, trichloroethene, vinyl
chloride, and 1,4-dichlorobenzene. The groundwater sample with the highest level of
volatile organic contamination was obtained from MW-8 which is located near the center
of the landfill.

Cobalt, barium and nickel were the only metals detected in the groundwater samples that
exceeded a standard. The highest concentration of these metals were detected in the
sample from MW-6 with cobalt at 167 ug/L, barium at 1,500 ug/L and nickel at 141 ug/L.

Monitoring wells MW-1 and MW-2 associated with the Pre-1991 Landfill. Benzene in a
concentration of 1.4 ug/L at MW-1 was the only contaminant detected above the 2L
Standard.

Groundwater from the Closed and Pre-1991 Landfills discharges to the unnamed
tributary of Crooked Creek. No volatile organic compounds or metals were detected in
the three surface water samples collected from the creek. These results are consistent
with previous data.
