1.0 INTRODUCTION
1.1 Site Information
The East Burke Landfill, Permit No. 12-02, is located in Burke County, North Carolina as
shown on Figure 1. The landfill was operated by Burke County as a municipal solid waste
(MSW) landfill between 1972 and 1988 and has been closed to the reception of waste since
1988.
1.2 Regulatory Status
The landfill is regulated under Rules .0500 and .0600 of the North Carolina Solid Waste
Management Regulations (NCSWMR) for MSW landfills closed prior to October 9, 1993.
The County monitors' groundwater at the landfill in accordance with criteria set forth in Rule
.0600 of the NCSWMR.
In March 1995, the North Carolina Department of Environment and Natural Resources
(NCDENR), now the Department of Environmental Quality (NCDEQ), requested that the
facility perform additional site contamination investigation activities due to the quantified
detections of organic constituents in the groundwater on site. In response to this request a
Water Quality Assessment Plan for the East Burke Landfill was submitted to the Solid Waste
Section (SWS) in September of 1995. Updates on Groundwater Assessment Activities were
submitted to NCDENR SWS in June 2003 and August 2003.
2.0 FACILITY MONITORING PROGRAM
2.1 Groundwater Monitoring Program
Groundwater monitoring at the East Burke Landfill is completed in accordance with the
monitoring requirements of Rule .0600 of the NCSWMR. Groundwater samples are collected
semiannually. The current compliance network consists of the following monitoring wells:
MW-1 (background), MW-2, MW-3, and AMW-1. A site plan indicating the facility and
waste boundaries in addition to monitoring well locations can be found in Drawing 1. All
monitoring wells are monitored for the NC Appendix I list of constituents.

2.2 Surface Water Monitoring Program
Surface water monitoring at the East Burke Landfill is completed in accordance with the
monitoring requirements of Rule .0600 of NCSWMR. Surface water samples are collected
semiannually and are analyzed for the NC Appendix I constituents.
The surface water monitoring network consists of two sampling points: SW-1 located
upstream from the sediment pond, and SW-2 located downstream from MW-3 and AMW-1.
The approximate locations of the sampling points are shown on Drawing 1.

3.0 DECEMBER 2018 SEMIANNUAL SAMPLING EVENT
3.1 Field Work
On December 3rd, 2018, personnel from Joyce Engineering (JOYCE) visited the East Burke
Landfill to obtain water levels to the nearest 0.01 foot, purge, and sample monitoring wells
MW-1, MW-2, MW-3, and AMW-1, and sample the two surface monitoring points, SW-1
and SW-2.
Monitoring wells were purged and sampled using disposable bailers during the December
2018 sampling event. Measurements of temperature, pH, specific conductivity, and turbidity
were recorded in the site log book prior to purging, after each purge volume, and during
sampling. Prior to sampling, laboratory -supplied containers were prepared with the following
information:
• Monitoring well number (completed by field personnel);
• Date and time of sample collection (completed by field personnel);
• Initials of sampling personnel (completed by field personnel);
• Project name and number (completed by the laboratory);
• Chemical preservative (completed by the laboratory); and
• Requested chemical analysis (completed by the laboratory).
Groundwater samples from each monitoring well were collected directly from the disposable
bailers in the provided laboratory containers either immediately after purging or within 24
hours of the final purge volume. Immediately after collection, the samples were placed on ice
in a laboratory provided cooler. Copies of the field data logs are provided in Appendix 1.
The surface water monitoring points SW-1 and SW-2 were collected directly from stream by
lowering a clean, unpreserved sample container into the stream flow and dispensing the water
into laboratory -prepared sample containers. Care was taken to avoid sample -induced
turbidity. At the time of sampling, surface water was also measured for temperature, pH,
specific conductivity, and turbidity and recorded in the field data log. Immediately after
December 2018 Semiannual Water Quality Monitoring Report Joyce Engineering
Burke County — East Burke Landfill, Permit No. 12-02 March 2019

collection, the samples were placed on ice in a laboratory -provided cooler. Copies of the field
data logs are presented in Appendix 1.
3.2 Laboratory Analysis and JOYCE Quality Control
The December 3rd, 2018 groundwater and surface water samples were submitted to Pace
Analytical Services, Inc. of Huntersville, North Carolina under chain -of -custody control for
analysis. JOYCE requested a Level II data report for the final laboratory report. The samples
were received by the laboratory on December 51h, 2018, in good condition, properly
preserved, and within analysis hold times.
In addition to samples collected for compliance monitoring at the East Burke Landfill, a Field
Blank was collected by JOYCE personnel as part of the December 2018 sampling event.
Also, a Trip Blank was prepared by the laboratory to accompany the volatile sampling during
shipment. The Field Blank was analyzed for the NC Appendix I list compounds while the
Trip Blank was analyzed for NC Appendix I VOCs.
Upon receipt of the laboratory data package, the data was reviewed by JOYCE personnel for
the following:
• General typographical errors;
• Correct analyses performed and within method specified hold times;
• Correct analyte lists;
• Biased data results based on Surrogate Recoveries, Matrix Spike, Matrix Spike
Duplicate, and Laboratory Control Samples;
• Blank qualified data (B-flags);
• Detections above the Method Reporting Limits (MRL);
• Detections above the 15A NCAC2L (NC2L) Groundwater Standards, SWS
Groundwater Water Protection Standards (GWPS), and/or 15A NCAC213
(NC2B) Surface Water Standards; and
• Detections that are above historical levels.
4.0 HYDROGEOLOGY
The surficial aquifer is believed to include the regolith and the underlying fractured
metamorphic bedrock. The regolith consists of alluvium, residual soils, saprolite, and
variably fractured and weathered layered metamorphic rock. In this regard, regolith behaves
similar to unweathered bedrock, except that fractures are more numerous and better connected
in the regolith, and will tend to have more isotropic hydraulic properties.
Groundwater discharges into an unnamed tributary to Lake Rhodhiss, northeast of the landfill.
A groundwater potentiometric surface map, developed from static water level data obtained
on December 3rd, 2018 is presented as Drawing 1.
Depth to groundwater was measured in the compliance monitoring wells at the site prior to
sampling. The groundwater elevations were calculated relative to the surveyed measuring

3

point (top of casing) for each monitoring well to ±0.01 ft. The groundwater elevations are
summarized in Table 1 for the December 2018 monitoring event. Historical groundwater
elevations are summarized in Table A2-1.
The potentiometric surface contours shown in Drawing 1 are based on data from the
December 2018 sampling event. Groundwater flow beneath the waste management unit is
primarily to the northeast. Estimated horizontal groundwater gradients (i) from the December
2018 groundwater elevations are presented in Table 2. The horizontal gradient (i) calculated
for the facility from the data was 0.0647.
Linear groundwater flow velocities (V) was estimated using the following modified Darcy
equation:
V = Kilne,
where:
V = average linear velocity (feet per day — ft/day);
K = hydraulic conductivity (ft/day);
i = horizontal hydraulic gradient; and
ne = effective porosity.
Hydraulic conductivity (K) was estimated at 3.28 ft/day based on slug tests from a nearby site
(John's River Landfill). An effective porosity (ne) of 20% was estimated based on typical
values for piedmont aquifers. The estimated linear groundwater flow velocity under the
facility is 387 ft/year (Table 2).
Because of our conservative estimate of effective porosity, actual groundwater velocities may
be significantly less than those calculated. Also, the modified Darcy equation makes the
simplified assumptions of a homogeneous and isotropic aquifer, which may yield inaccurate
results when applied to heterogeneous and/or anisotropic conditions such as are believed to
exist at this site.
Migration of groundwater contaminants are expected to follow the general groundwater flow
paths and there are no known preferred pathways or barriers to groundwater flow that could
significantly affect plume migration or the effectiveness of the groundwater monitoring
network to monitoring plume migration. The current groundwater monitoring network
remains sufficient for monitoring the groundwater at this facility.
5.0 DATA ANALYSIS
The final results from the December 2018 sampling event were received on December 17tn,
2018, for all monitoring wells (MW-1, MW-2, MW-3, and AMW-1) and surface water
monitoring locations (SW-1 and SW-2). All analytical results can be found in Appendix 1.
Table 3 summarizes the constituents in all monitoring well and surface water samples for the
December 2018 event. Constituents in exceedance of the appropriate standards are
summarized in Table 4. Field Parameters for the December 2018 sampling event are
summarized in Table 5.

Analytical results from monitoring wells were compared directly to the North Carolina
Groundwater Standards found in 15A NCAC 02L.0202 (NC2L Standards) or the NCDEQ
Solid Waste Section Groundwater Protection Standards (GWPS) for constituents with no
listed NC2L Standard. Note that estimated concentrations below the Method Reporting Limit
(MRL) are not considered exceedances of the standard, even if the estimated value is higher
than the standard.
Analytical results for surface water samples were compared directly to either the Freshwater
Aquatic Life Surface Water Standards or Fish Consumption Surface Water Standards
(whichever was lower) found in 15A NCAC 02B (NC213 Standards). For metals which have
hardness -dependent NC213 Standards, the standards based on a default hardness of 25 mg/L
was used. For constituents which have NC213 standards for both chronic and acute exposure,
the lower of the two standards was used. For constituents with no NC213 standards, the results
were compared to either the NC protective standard (NCPS) or the EPA naturally
recommended water quality standard (NRWQS). Note that estimated concentrations below
the MRL are not considered exceedances of the standard, even if the estimated value is higher
than the standard.
5.1 Analytical Results and Comparison to Standards
5.1.1 Groundwater
Inorganic constituents detected at quantified concentration in groundwater during the
December 2018 sampling event are listed in Table 3. All concentrations are reported in
micrograms per liter (µg/L). Concentrations with a "J" are considered to be estimated. Bold
values indicate concentrations above the NC 2L or GWPS in the groundwater samples.
Historically detected constituents in groundwater can be found in Table A2-2.
Inorganic constituents, barium, cobalt, nickel, and thallium were detected above the MRL.
Cobalt (MW-1 and MW-3) and thallium (MW-2 and MW-3) were detected at quantified
concentrations exceeding the NC 2L or GWPS.
Organic constituents were detected in all of the monitoring wells (MW-1, MW-2, MW-3, and
AMW-1); however, only 1,4-dioxane (p-dioxane) and cis-1,2-dichloroethene were detected at
quantified concentrations above the MRL. Only 1,4-dioxane (p-dioxane) was detected in
exceedance of NC 2L standard in MW-2 and MW-3. In general, these detections are
consistent with historical data for the inorganic and organic constituents.
5.1.2 Surface Water
During the December 2018 sampling event barium, cobalt, thallium, cis-1,2- dichloroethene,
and 1,4-dioxane were detected at quantified concentrations above the MRL in surface water
samples. Cobalt was detected above the NCPV in surface water monitoring point SW-2.
Historical surface water data can be found in Table A2-3.
December 2018 Semiannual Water Quality Monitoring Report Joyce Engineering
Burke County — East Burke Landfill, Permit No. 12-02 March 2019

6.0 CONCLUSION
1,4-Dioxane was detected in exceedances of groundwater protection standards in MW-2 and
MW-3. 1,4-Dioxane analyses were required by the NCDEQ for the first time during the
December event, and the NCDEQ has not yet issued a policy concerning regulatory response
to 1,4-dioxane exceedances. We recommend continuing to sample for 1,4-dioxane in order to
establish possible trends and/or seasonal variability. 1,4-Dioxane was detected in surface
water samples SW-1 and SW-2. There is no NC2B surface water standard for 1,4-dioxane;
however, there is a NC Protective Value for 1,4-dioxane, which is 80 µg/l for non -water -
supply surface waters. None of the 1,4-dioxane detections exceeded the NC Protective Value.
Cobalt was detected in SW-2 in exceedance of the NCPV.
According to historical groundwater data, inorganic and organic constituents detected above
the NC2L or GWPS in groundwater samples collected during the December 2018 sampling
event are consistent with previous events with the exception of the 1,4-dioxane, which was
analyzed for the first time. Based on the results of this groundwater monitoring event the
groundwater monitoring network remains adequate to monitor groundwater at the site. The
next semiannual sampling event is tentatively scheduled for the May 2019.
