1.0 INTRODUCTION
This report summarizes the monitoring results from the April 25 - 28, 2017, groundwater, surface water,
and leachate sampling at Phase III of the White Street Landfill in Greensboro, North Carolina (NC). The
active Subtitle D municipal solid waste (MSW) facility is monitored in accordance with Title 15A NCAC
13B.1633.
The facility is located in central Guilford County and is comprised of a closed, unlined MSW facility (Phase I),
an active unlined construction and demolition debris (C&D) over MSW facility (Phase II), an active Subtitle
D MSW facility (Phase III), and an active Type I compost facility. Phase II is currently in Assessment
Monitoring and Corrective Action for several detected volatile organic constituents (VOCs) and inorganic
constituents that exceed their respective groundwater standards. Phase III is in Detection Monitoring.
The facility is owned and operated by the City of Greensboro under Permit Nos. 41-03 and 41-12 issued
by the NC Department of Environmental Quality (DEQ, formerly NC Department of Environment and Natural
Resources). The northeastern portion of the landfill property is comprised of the Phase I and Phase II
landfills, which are covered under Permit No. 41-03. The southwestern portion of the facility is comprised
of the Phase III, which is covered under permit No. 41-12. The water quality monitoring results for the
Phase II and Phase III facilities are submitted under separate covers.
1.1 Site Description and Background
The location of the facility is shown on the inlay on Figure 1. The White Street Landfill is located
approximately 5 miles northeast of downtown Greensboro, North Carolina in Guilford County. Access to
the site is from White Street, which runs eastward towards the site off of Summit Avenue and NC Highway
29.
Part of the James River watershed, North Buffalo Creek flows from southwest to northeast along the
northwestern border of the facility and then flows eastward, away from the facility near the northeastern
end of the facility. The location of this surface water feature and its associates tributaries are shown on the
inlay on Figure 1.
Based on the topography as shown on Figure 1, topographic surface elevations at the facility range from
approximately 700 feet above mean sea level (AMSL) to nearly 850 feet AMSL. The site is surrounded by
wooded and agricultural properties to the northwest, residential properties to the south and southwest, and
residential and wooded properties to the east.
The Phase I landfill is located southwest of the active C&D landfill on top of the Phase II landfill and
northeast of the active Phase III landfill. The property also includes an active Type I compost facility located
to the east of the Phase I landfill and south of the Phase II landfill.

1.2 Compliance Monitoring History
The Phase III landfill was approved for operation by the NC DEQ on December 7, 1997. The facility’s
approved monitoring network for the Phase III landfill is currently comprised of 12 monitoring wells, which
monitor the uppermost aquifer beneath the facility. Monitoring wells MW-15 and MW-16 are upgradient
background wells for the Phase III landfill. Monitoring wells MW-17, MW-18, MW-19, MW-20, MW-21,
MW-22, MW-23, MW 24, MW-25, and MW-25D are downgradient compliance wells for the Phase III landfill.
The monitoring well locations are shown on Figure 1. Phase III groundwater samples are analyzed for NC
Appendix I list of constituents semi-annually.
The Phase III landfill’s monitoring network also includes four surface water monitoring points, which are
shared with the Phase I and Phase II landfills. Surface water monitoring points SW-1, SW-2, and SW-3
are upstream monitoring locations and SW-4 is a downstream monitoring location. Surface water point
SW-1 is located along North Buffalo Creek, west of the facility, along Summit Avenue. Surface water point
SW-2 is located west of the facility and collected from a tributary to North Buffalo Creek that flows from
south to north. Surface water point SW-3 is located west of the facility, downstream of SW-1 and upstream
of the confluence of North Buffalo Creek and the tributary from which SW-2 is sampled. Surface water
point SW-4 is located downstream of the facility along North Buffalo Creek. The locations of the surface
water points are shown on Figure 2. Surface water samples were analyzed for NC Appendix I list of
constituents semi-annually.
The Phase III landfill has remained in the Detection Monitoring Program since water quality monitoring
began at the facility. Based on historical sampling results, no groundwater quality standards have been
exceeded for NC Appendix I VOCs at this facility. An Alternate Source Demonstration (ASD) was submitted
on October 28, 2016, at the request of the NC DEQ to address groundwater quality standard exceedences
of antimony, cobalt, and vanadium in samples from downgradient monitoring wells. The ASD determined
that the concentrations of antimony, cobalt, and vanadium could be reasonably attributed to the natural
occurrence of these inorganic constituents from native, residual soil.
1.3 Hydrogeologic Setting
The White Street Landfill is located within the Carolina Slate Belt of the Piedmont Physiographic Province
of NC (NCGS, 1985). Generally, the Carolina Slate Belt consists of Late Proterozoic to Cambrian volcanic
and greenschist-facies, metasedimentary rocks intruded by plutonic suites (Butler and Secor, 1991). The
site geology is characterized by a regional-scale felsic intrusive complex, which consists mainly of white to
gray, fine- to coarse-grained, massive to foliated metamorphosed granitic rock. The region is characterized
by regional and small scale Mesozoic diabase dikes.
The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of
saprolite and partially weathered rock (PWR). Groundwater occurs at depths of approximately 5 to 30 feet
August 2017 3 1668421.101

below ground surface. Depth to water measurements, obtained on April 25, 2017, are summarized in Table
1 and were used to prepare a groundwater surface contour map presented on Figure 1.
As presented, the groundwater flow in the uppermost aquifer beneath the site is generally to the northwest
toward North Buffalo Creek, which is located along the northwestern property boundary of the site. The
groundwater surface contour map and interpreted flow directions are generally consistent with previously
submitted groundwater contour maps and flow directions for this facility.
Based on the April 2017 groundwater surface contour map, the hydraulic gradient in the shallow aquifer
underlying the site, as measured along the conceptual flow paths shown on the contour map, was calculated
to be approximately 0.02 feet/foot. Groundwater velocities were calculated using a hydraulic conductivity
of 2.61 X 10-4 centimeters per second (cm/s), which is the average of the hydraulic conductivities calculated
for the hydrogeologic units present at the facility’s Phase II and Phase III landfills. This average is based
on slug test data by BPA Environmental & Engineering Inc. (Phase II) and G.N. Richardson & Associates
(Phase III). Although no data is available for the Phase I landfill, it is assumed that the whole facility either
share hydrogeologic units or have similar characteristics (S&ME, 2017). The estimated effective porosity
of the shallow aquifer is expected to range from 0.20 (saprolite) to 0.09 (fractured rock). The effective
porosity of saprolite was used in calculations to provide a conservative estimate of groundwater flow.
Using the above values, the estimated rate of groundwater flow for the uppermost aquifer beneath the
facility was calculated using the following modified Darcy equation:
Vgw = Ki/ne
where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic
gradient, and ne = effective porosity.
The average estimated linear groundwater flow velocity under the waste management unit is approximately
269 feet/year toward the northwest, which is generally consistent with previous estimates (Table 2). The
linear velocity equation above makes the simplified assumptions of a homogeneous and isotropic aquifer.
Therefore, this equation represents a likely average value for the uppermost aquifer and does not account
for heterogeneous and/or anisotropic conditions that may be present in the uppermost aquifer at the facility.
2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION
Field activities conducted as part of the April 2017 sampling event are discussed in the following sections.
2.1 Visual Inspection Program
In order to detect a potential release at the earliest possible time, the visual inspection program is used at
the Phase III landfill by the sampling personnel. This program includes physical indicators such as potential
water table mounding beneath the waste management unit, physical examination of any stresses in
biological communities, visible signs of leachate migration (i.e., leachate seeps), unexplained changes in
August 2017 4 1668421.101

soil characteristics, and any other change to the environment due to the waste management unit. During
the April 2017 compliance monitoring event, no physical indicators of a potential release were observed in
the vicinity of the waste management areas by the sampling personnel.
2.2 Well Network and Groundwater Elevation Measurements
The current network of groundwater monitoring wells at the Phase III landfill consist of two upgradient
background wells (MW-15 and MW-16) and 10 downgradient compliance wells (MW-17, MW-18, MW-19,
MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and MW-25D). Available monitoring well construction
information for all site monitoring wells is summarized on Table 3, and the well locations are shown on
Drawing 1. The well locations were selected to yield groundwater samples representative of the conditions
in the uppermost aquifer underlying the facility, and to monitor for potential releases from the landfill unit.
Three upstream surface water monitoring points (SW-1, SW-2, and SW-3) and one downstream surface
water monitoring point (SW-4) are also monitored.
Depth-to-water measurements are recorded to the nearest 0.01 foot prior to initiating groundwater purging
and sampling activities. The respective groundwater level elevations for this event are presented in Table 1.
The historical water level data are also shown on this table. As presented, recent groundwater elevation
data for the monitoring well network indicate that the hydraulic head level in the uppermost aquifer beneath
the facility is fairly consistent, with temporal variation from the long-term average limited to approximately
5 - 10 feet (plus or minus) under normal conditions. The range in fluctuation appears to be greatest in the
upgradient background wells, which are located in a groundwater recharge area. The range in fluctuation
in the downgradient compliance wells, which are located near groundwater discharge areas, is less,
presumably due to the stabilizing effect of the hydraulic discharge boundary.
2.3 April 2017 Monitoring Event
Personnel from Golder visited the facility from April 25 - 28, 2017, to purge and sample monitoring wells
and to sample surface water monitoring points
Monitoring wells were purged and sampled using the dedicated pumps at the facility following low-flow
micropurge procedures. Measurements of temperature, pH, specific conductivity, turbidity, dissolved
oxygen, and oxidation reduction potential were recorded on approximately 5-minute intervals, depending
on the purge rate. In general, the purge rate for each well was matched to the yield of the monitoring well,
as determined by continuously monitoring the depth to the water, up to a maximum purge rate of 300
milliliters per minute. Purging was continued until stabilization was indicated by the water quality
parameters.
Prior to sampling, the laboratory-supplied sample containers were prepared. Each sample container was
labeled with the sample identification number, sampling personnel, date and time of sample collection,
project name and number, and requested chemical analyses.
August 2017 5 1668421.101

The required groundwater samples were collected directly from the dedicated bladder pump’s discharge
lines into the labeled, laboratory-supplied, pre-preserved sample containers after purging was completed
based on stabilization of all water quality parameters. After collection, the samples were placed in a cooler
on ice, under chain-of-custody control. Copies of the sampling logs are presented in Appendix A. Included
in each log is a description of the sampling equipment, sampling method and location, field observations,
and water quality measurements.
The surface water samples were collected directly from the stream, by lowering the sample containers into
the stream flow with the opening facing downstream from the current flow, taking care to prevent the
overflow of the sample containers and to minimize sample-induced turbidity. However, due to access
limitations, SW-3 was collected by lowering a disposable bailer into the stream from a bridge and then filling
the sample containers directly from the bailer. Measurements of temperature, pH, specific conductivity,
turbidity, dissolved oxygen, and oxygen reduction potential were measured directly from the stream and
recorded during the collection of the surface water samples. After collection, the surface water samples
were placed in a cooler on ice, under chain-of-custody control. Copies of the sampling logs are presented
in Appendix A. Included in each log is a description of the sampling equipment, sampling location, sampling
method, field observations, and water quality measurements.
The leachate sample is collected from a leachate sump located on the northeast corner of the Phase III
landfill. The sample is collected by lowering a disposable bailer into the leachate and then filling the sample
containers directly from the bailer. Measurements of temperature, pH, specific conductivity, and turbidity
were measured during the collection of the leachate sample. After collection, the leachate sample was
placed in a cooler on ice, under chain-of-custody control. A copy of the sampling log is presented in
Appendix A. Included in the log is a description of the sampling equipment, sampling location, sampling
method, field observations, and water quality measurements.
2.4 Laboratory Analysis Program
The April 2017 groundwater, surface water, and leachate samples were submitted to Environmental
Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain-of-custody control for analysis.
Groundwater samples were analyzed for NC Appendix I constituents. Surface water samples were
analyzed for NC Appendix I constituents. The leachate sample was analyzed for the required NC DEQ
parameters (NC Appendix I, BOD, COD, nitrate, sulfate, and phosphate). The samples were received at
the laboratory in good condition and were properly preserved.
2.5 April 2017 Sampling Results
Analytical results for the April 2017 groundwater samples are summarized in Tables 4 and 5 with available
historical data. Analytical results and field parameters for the April 2017 surface water samples are
summarized in Tables 6 and 7 with available historical data. Analytical results and field parameters for the
April 2017 leachate sample is summarized in Table 8 with available historical data. The laboratory
August 2017 6 1668421.101

certificate-of-analysis, chain-of-custody form and laboratory data review for the sampling event are included
in Appendix B.
As presented in Table 4, one NC Appendix I inorganic constituent was detected above the Solid Waste
Section Reporting Limit (SWSL) in samples from one or more downgradient compliance monitoring wells
at the Phase III landfill during the April 2017 monitoring event. Barium was detected above the SWSL in
samples from upgradient well MW-16 and downgradient wells MW-22 and MW-24. No NC Appendix I
VOCs were detected above their respective SWSLs in samples from downgradient monitoring wells during
the April 2017 monitoring event.
As presented in Table 6, two NC Appendix I inorganic constituents were detected above their respective
SWSLs in one or more surface water samples during the April 2017 event. Copper was detected at a
concentration that exceeded the SWSL in the sample from upstream surface water monitoring point SW-3.
Zinc was detected above the SWSL in the samples from upstream points SW-1 and SW-3, and downstream
point SW-4. No NC Appendix I VOCs were detected at concentrations that exceeded the SWSLs during
the event in surface water monitoring points. Detected constituents and concentrations for leachate
parameters were generally consistent with historical data.
3.0 LABORATORY AND FIELD QA/QC
A duplicate sample was collected at Phase III well MW-23 by Golder personnel as part of the April 2017
sampling event. ENCO analyzed the duplicate sample for the NC Appendix I list of constituents. A
laboratory-prepared trip blank accompanied the volatile sample containers to and from the laboratory.
ENCO analyzed the trip blank for NC Appendix I VOCs. Reviews of the laboratory data were performed by
Golder personnel and are included in Appendix B.
Four of five constituents were detected in the duplicate sample and the sample from MW-23. The
concentrations from the duplicate sample and the sample from MW-23 were very similar. Chloromethane
was detected in the sample from MW-23 at an estimated concentration, but was not detected in the
duplicate sample. The results do not identify any irregularities related to laboratory analyses and results
for this event are generally consistent with historical data.
Acetone was detected at estimated concentrations in two trip blanks during the April 2017 event. Based
on data reviews performed by Golder, the concentrations of acetone in samples from MW-17, MW-18, MW-
19, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, MW-25D, SW-1, SW-2, SW-3, and SW-4 are
considered blank-qualified. The laboratory has verified that they received contaminated bottleware from a
vendor that has resulted in random acetone and chloromethane detections. A letter from the laboratory
documenting this is provided in Appendix B.
4.0 DATA EVALUATION
The results of the data evaluations are presented in the following sections.
August 2017 7 1668421.101

4.1 North Carolina Groundwater and Surface Water Quality Standard
Comparisons
As presented in Table 4, no NC Appendix I inorganic constituents were detected above their respective
SWSLs and applicable water quality standards in samples from groundwater monitoring wells during the
April 2017 event. Cobalt was detected at estimated concentrations below the SWSL and the Solid Waste
Section Groundwater Protection Standard (SWS GPS) in the samples from upgradient well MW-16 and
downgradient well MW-24. Thallium was detected at estimated concentrations below the SWSL and the
SWS GPS in the samples from downgradient wells MW-20, MW-21, MW-22, and MW-24. Vanadium was
detected at estimated concentrations below the SWSL and the SWS GPS in the samples from upgradient
well MW-16 and downgradient wells MW-17, MW-19, MW-20, MW-23, and MW-25D. No further action is
warranted because the detected constituents were reported at concentration below the SWSLs. Further,
concentrations of cobalt, thallium, and vanadium were similar in upgradient and downgradient wells, which
support that the constituents are naturally occurring. No NC Appendix I VOCs were detected above their
respective SWSLs and applicable water quality standards in samples from downgradient wells during the
April 2017 event.
As shown in Table 6, copper and zinc were reported above their respective SWSLs and the Freshwater
Acute and Chronic Standards from upstream monitoring point SW-3 at concentrations similar to previous
events. Copper was also reported at estimated concentrations below the SWSL, but above the Freshwater
Acute Standard and/or the Chronic Standard in the samples from upstream points SW-1 and SW-2, and
downstream point SW-4. Lead was reported at an estimated concentration below the SWSL, but above
the Freshwater Chronic Standard in the sample from upstream point SW-3. Because the SWSL and surface
water standard exceedances were in an upstream sample, the exceedances are not likely related to landfill
activities from the facility and no further action is warranted. No VOCs were detected above their respective
SWSLs and NC 2L Standards in samples from surface water monitoring points during the April 2017 event.
5.0 CONCLUSIONS
Based on the results summarized herein, the City of Greensboro will continue monitoring the uppermost
aquifer beneath this facility in accordance with the requirements of the Detection Monitoring Program as
outlined in Title 15A NCAC 13B.1633. The next sampling event is tentatively scheduled for October 2017.

have been ‘flagged’ with a ‘B’ where detected in other samples as appropriate and a
laboratory narrative was provided. If the sample was flagged by the laboratory and is
not within 5X of the concentration in the blank (or 10X for commonly detected laboratory
contaminants-acetone, methylene chloride and phthalates), list below with explanation
if flags should be removed. If flags need to be added for samples, also list below.

 Trip Blank
o Acetone @ 20 ug/L (J) – add B flags to: MW-15, MW-16, MW-17, MW-18, MW-19,
MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and MW-25D

MG It is clear from the laboratory report that samples have or have not been diluted during
analysis, and if the samples have been diluted, the result is reported as a multiple of
the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should
be reported as 10). Those that have been diluted are listed below with the dilution
factor.

MG The report provides the reporting limit for each constituent.
MG The results were reported at or below their proper reporting limits (e.g., NC Solid Waste
Section Reporting Limits-SWSLs). Those that are not reported correctly are listed
below (by constituent) with the proper reporting limit listed beside them. State if the
reporting limit error is due to dilutions.

MG No inorganic or organic constituents were reported above their respective NC 2L
Drinking Water Standards or Groundwater Protection Standards (GPS) in wells or
field/equipment/trip blanks or above applicable Surface Water Standards for surface
water points.
 Cobalt (SWS GWPS = 1 ug/L) o MW-16 @ 1.28 ug/L (J)

3.0 LABORATORY QUALITY CONTROL REVIEW

MG Laboratory analyzed at least one internal blank for each method, where applicable.
MG Laboratory blank is interference-free.
MG Surrogate recoveries are provided for each analytical method, where applicable.
MG Surrogate recoveries for each method are within the acceptable limits (i.e., at least
50% of the surrogates were within range).
MG MS/MSD/LCS data results are provided for each analytical method.
MG MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at
least 1 of the 3 were within range).
 The BOD Method Blank exceeded the method required oxygen depletion of less than
0.20 mg/L, and the average dissolved oxygen uptake of the seeded control (LCS) did not meet the requirement of 0.6 to 1.0 mg/L. The reported results should be considered estimated. The spike recoveries of COD and Nitrite were outside of
control limits for the MS and/or MSD samples. The QC batch was approved based on acceptable LCS recovery of these analytes.

4.0 ANALYTE LISTS/METHODS

MG The proper number of constituents are present for each analyte list as identified
above (including detects where applicable).

MG Proper EPA SW-846 analytical methods were used for analysis.

5.0 DATA REPORTING

MG All analytical reporting associated with the event was performed by the contracted lab.
MG Trip, field and/or equipment, and laboratory blank results have all been reported. All
detects for blanks are listed below by constituent. All laboratory method blanks, if any,
have been ‘flagged’ with a ‘B’ where detected in other samples as appropriate and a
laboratory narrative was provided. If the sample was flagged by the laboratory and is
not within 5X of the concentration in the blank (or 10X for commonly detected laboratory
contaminants-acetone, methylene chloride and phthalates), list below with explanation
if flags should be removed. If flags need to be added for samples, also list below.

MG It is clear from the laboratory report that samples have or have not been diluted during
analysis, and if the samples have been diluted, the result is reported as a multiple of
the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should
be reported as 10). Those that have been diluted are listed below with the dilution
factor.

 Leachate o Antimony @ DF = 10x o Chemical Oxygen Demand @ DF = 2x o Thallium @ DF = 10x o VOCs @ DF = 10x

MG The report provides the reporting limit for each constituent.
MG The results were reported at or below their proper reporting limits (e.g., NC Solid Waste
Section Reporting Limits-SWSLs). Those that are not reported correctly are listed
below (by constituent) with the proper reporting limit listed beside them. State if the
reporting limit error is due to dilutions.

MG No inorganic or organic constituents were reported above their respective NC 2L
Drinking Water Standards or Groundwater Protection Standards (GPS) in wells or
field/equipment/trip blanks or above applicable Surface Water Standards for surface
water points.

 1,4-Dichlorobenzene (NC 2L = 6 ug/L; EPA MCL = 75 ug/L)
o Leachate @ 9.9 ug/L (J)

 4-Methyl-2-pentanon (NC 2L = 560 ug/L; EPA MCL = 5 ug/L) o Leachate @ 49 ug/L (J)

 Antimony (NC 2L = 1 ug/L; EPA MCL = 6 ug/L)
o Leachate @ 10.9 ug/L (J)
 Arsenic (NC 2L = 10 ug/L; EPA MCL = 10 ug/L) o Leachate @ 13.2 ug/L
