RE: WATER QUALITY MONITORING REPORT, FIRST SEMI-ANNUAL 2017 SAMPLING EVENT
WHITE STREET LANDFILL - PHASE II, PERMIT NO. 41-03
GREENSBORO, NORTH CAROLINA
Dear Jackie,
On behalf of the City of Greensboro, Golder Associates NC, Inc. (Golder) is submitting the enclosed
Water Quality Monitoring Report, which documents the results of the April 25 - 28, 2017, compliance
monitoring event for Phase II at the White Street Landfill.
Barium, cobalt, copper, nickel, and zinc were detected at concentrations above the SWSLs in samples
from one or more downgradient monitoring compliance wells during this event. Of these, cobalt was
detected at concentrations above the Solid Waste Section Limit (SWSL) and the Solid Waste Section
Groundwater Protection Standard (SWS GPS) in the samples from downgradient compliance wells II-1
and II-3 during the April 2017 event. Cobalt and vanadium were detected at estimated concentrations
below the SWSLs, but above the SWS GPS in the samples from one or more downgradient compliance
wells. The concentrations of cobalt and vanadium are considered naturally occurring as determined in
the November 2007 Alternate Source Demonstration (ASD); therefore, no further action is warranted.
Thallium was also detected at estimated concentrations below the SWSL, but above the SWS GPS in the
samples from one or more downgradient compliance wells. Because these concentrations are below the
SWSL and are considered estimated, no further action is warranted.
During this event, nine volatile organic constituents (VOCs) were detected in samples from one or more
downgradient compliance monitoring wells at concentrations above SWSLs: benzene;
1,4-dichlorobenzene; chlorobenzene; 1,1-dichloroethane; cis-1,2-dichloroethene; toluene;
tetrachloroethene; trichloroethene; and vinyl chloride. Of these, four VOCs were detected above their
respective SWSLs and applicable water quality standards: benzene; 1,1-dichloroethane;
tetrachloroethene; and vinyl chloride. The concentrations of detected NC Appendix I VOCs were similar
to previous events.

Barium, cadmium, cobalt, copper, and zinc were detected above their respective SWSLs in samples from
one or more of the corrective action sentinel wells during this event. The concentration of cadmium at
SMW-1 was above the SWSL and the SWS GPS. Cobalt and vanadium were detected at estimated
concentrations below the SWSLs, but above the SWS GPS in the samples from one or more sentinel
wells. The detections of cadmium, cobalt, and vanadium are considered naturally occurring as
determined in the November 2007 ASD; therefore, no further action is warranted. No NC Appendix I
VOCs were detected above their respective SWSLs and applicable water quality standards in sentinel
wells during the April 2017 event.
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 points SW-4 and SW-5. Lead was reported at an estimated concentration below the SWSL,

1.0 INTRODUCTION
This report summarizes the monitoring results from the April 25 - 28, 2017, groundwater and surface
water sampling at Phase II of the White Street Landfill in Greensboro, North Carolina (NC). The active
unlined construction and demolition debris (C&D) over municipal solid waste (MSW) facility is monitored
in accordance with Title 15A NCAC 13B.1635 and .1637.
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 I 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 II landfill is located northeast of the closed Phase I 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 original monitoring network consisted of one upgradient well (MW-13) and five downgradient wells
(II-1, II-2, II-3, II-4, and II-5). An additional upgradient well (MW-14) and three additional downgradient
wells (II-6, II-7, and II-8) were installed in 1995. Assessment monitoring at the Phase II facility was
initiated in 1997 due to groundwater exceedances of NC Appendix I constituents. The C&D waste unit
began accepting waste over top of the closed Phase II MSW waste unit in 1998. Well II-7B was installed
in December 2000. Four monitoring wells (II-9, II-10, II-11, and II-12) were installed in March 2005 as
part of the Nature and Extent Study (NES). Well II-12 became part of the compliance network.
In October 2006, the City submitted an Alternate Source Demonstration (ASD) to address NC Appendix I
inorganic compounds detected in groundwater samples from the Phase II area. The ASD presented data
to support that concentrations of barium, cadmium, cobalt, vanadium, and zinc detected at site monitoring
wells are naturally occurring and was approved by the NC DEQ by letter on November 15, 2007.
The Phase II facility is currently in corrective action due to the detection of volatile organic compounds
(VOCs). The Corrective Action Plan (CAP) was approved by the NC DEQ on June 24, 2008, which
proposed phytoremediation and monitored natural attenuation (MNA) as the remedial strategy. Three
sentinel monitoring wells (SMW-1, SMW-3, and SMW-4) were installed in June 2010 and the EBuffer®
hybrid poplar trees were installed between March and November 2010. Well II-9 also serves as a
sentinel well for the corrective action monitoring program. Monitoring well II-3B was installed in June
2011 to monitor groundwater quality downgradient of II-3, which has been impacted due to its close
proximity to waste.
The Phase II landfill’s compliance monitoring network is currently comprised of 12 monitoring wells, which
monitor the uppermost aquifer beneath the facility. Monitoring wells MW-13 and MW-14 are the
upgradient wells for the Phase II landfill, with MW-13 being a shared upgradient well with the Phase I
landfill. Wells II-1, II-2, II-3, II-4A, II-5, II-6, II-7, II-7B, II-8, and II-12 are downgradient compliance wells
for the Phase II landfill. Well II-3B is sampled to monitor water quality downgradient of II-3. Groundwater
samples are analyzed for the NC Appendix I list of constituents plus NC Appendix II ‘detects’ during the
first semi-annual water quality monitoring event of each year and are analyzed for the NC Appendix II list
of constituents during the second semi-annual water quality monitoring event of each year. Currently,
there are not additional ‘detects’ to be analyzed during the first semi-annual water quality monitoring
events of each year.
The corrective action monitoring activities include semi-annual monitoring of the four sentinel wells (II-9,
SMW-1, SMW-3, and SMW-4). Three compliance monitoring wells (II-1, II-7, II-7B) also serve as sentinel
wells for the corrective action program. Groundwater samples from the sentinel wells are analyzed for the
same parameters as the compliance monitoring wells. MNA parameters are collected semi-annually from
upgradient well MW-13 and sentinel wells II-1, II-9, and SMW-3. The MNA parameters include chloride,
August 2017 3 1668421.101

nitrate, sulfate, sulfide, ethene, ethane, methane, total organic carbon (TOC), alkalinity, volatile fatty acids
(VFAs). A Corrective Action Performance Evaluation Report (CAPER) is to be prepared and submitted to
the NC DEQ every five years to evaluate MNA and the phytoremediation at the Phase II landfill. The next
CAPER is to be submitted prior to the second semi-annual water quality monitoring event of 2017.
The facility’s monitoring network also includes five surface water sampling points, SW-1, SW-2, SW-3,
SW-4, and SW-5. Surface water point SW-1 is the facility’s upstream sampling point located along North
Buffalo Creek, west of the facility, along Summit Avenue. Surface water point SW-2 is collected from a
tributary to North Buffalo Creek that flows from south to north into the stream, just west of the facility.
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 points
SW-4 and SW-5 are both located downstream of SW-1, SW-2, and SW-3 along North Buffalo Creek.
Surface water point SW-5 is located within the facility’s property, at the northern end of the Phase II
landfill and SW-5 is located to the east of the facility, off of Rankin Mill Road. Surface water points SW-1,
SW-2, SW-3, and SW-4 are sampled in conjunction with the groundwater monitoring wells in accordance
with the facility’s permits and Water Quality Monitoring Plan for the Phase I, Phase II, and Phase III
landfills. Surface water point SW-5 is only sampled in accordance for with the permit 41-03, which
includes the Phase I and Phase II landfills, but does not include the Phase III landfill.
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 1 to 30
feet 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 0.03 feet/foot. Groundwater velocities were calculated using a hydraulic
August 2017 4 1668421.101

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 354 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 II 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 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 compliance network of groundwater monitoring wells at the Phase II landfill consist of two
upgradient background wells (MW-13 and MW-14), 10 downgradient compliance wells (II-1, II-2, II-3,
II-4A, II-5, II-6, II-7, II-7B, II-8, and II-12), one assessment well (II-3B), and four sentinel wells (II-9,
August 2017 5 1668421.101

SMW-1, SMW-3, SMW-4). Available monitoring well construction information for all site monitoring wells
is summarized on Table 3, and the well locations are shown on Figure 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 two downstream surface water monitoring points
(SW-4 and SW-5) 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 - 20 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.
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.
August 2017 6 1668421.101

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.
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 and surface water samples were analyzed for NC Appendix I list of constituents. Both the
Phase I and Phase II landfills share background monitoring well MW-13 and therefore, MW-13 was
analyzed for NC Appendix I constituents plus mercury. Upgradient well MW-13 and sentinel wells II-1,
II-9, and SMW-3 were also analyzed for approved MNA parameters. 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. The laboratory certificate-of-analysis,
chain-of-custody form and laboratory data review for the sampling event are included in Appendix B.
2.5.1 Compliance Monitoring
As presented in Table 4, five NC Appendix I inorganic constituents were detected above the Solid Waste
Section Limits (SWSLs) in samples from one or more downgradient compliance monitoring wells at the
Phase II landfill during the April 2017 monitoring event. Barium was detected above the SWSL in
samples from downgradient wells II-1, II-3, II-4A, II-5, II-8 and I-12. Cobalt was detected above the SWSL
in samples from downgradient wells II-1 and II-3. Copper was detected above the SWSL in samples from

sample from II-8.
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 points SW-4 and SW-5. No NC Appendix I VOCs were detected at concentrations that
exceeded the SWSLs during the event in surface water monitoring points.
2.5.2 Corrective Action Monitoring
As presented in Table 4, five NC Appendix I inorganic constituents were detected above the SWSLs in
samples from one or more downgradient compliance monitoring wells at the Phase II landfill during the
April 2017 monitoring event. Barium was detected above the SWSL in samples from wells II-1, II-3A,
SMW-1, and SMW-3. Cadmium was detected above the SWSL in the sample from well SMW-1. Cobalt
was detected above the SWSL in the sample from well II-1. Copper was detected above the SWSL in the
samples from wells II-1 and SMW-1. Zinc was detected above the SWSL in samples from wells II-9 and
SMW-1.
As presented in Table 4, two NC Appendix I VOCs were detected above their respective SWSLs during
the April 2017 monitoring event. As discussed in the previous section, 1,4-dichlorobenzene was detected
above the SWSL in sample from well II-1. Constituent cis-1,2-dichloroethene was also detected above
the SWSL in the sample from II-9.
3.0 LABORATORY AND FIELD QA/QC
A duplicate sample was collected at Phase II well II-4A 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.
The same constituents were detected in the duplicate sample and the sample from II-4A. Further, the
concentrations from the duplicate sample and the sample from II-4A were very similar. The results do not
identify any irregularities related to laboratory analyses.
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-13, MW-14,
II-1, II-2, II-3, II-3B, II-4A, II-5, II-6, II-7, II-7B, II-8, II-9, II-12, SMW-1, SMW-3, SW-1, SW-2, SW-3, SW-4,
August 2017 8 1668421.101

and SW-5 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 the contamination is provided in Appendix B.
Copper was detected at an estimated concentration in a laboratory method blank during the event. The
concentrations of copper in samples from MW-13, II-5, II-7B, II-8, II-9, SMW-3, and SMW-4 are
considered blank-qualified.
4.0 DATA EVALUATION
The results of the data evaluations are presented in the following sections.
4.1 North Carolina Groundwater and Surface Water Quality Standard
Comparisons
Analytical results for the April 2017 groundwater samples are summarized in Tables 4 and have been
compared to applicable water quality standards in Section 4.1.1. Analytical results for the April 2017
surface water samples are summarized in Tables 6 and have been compared to applicable surface water
standards in Section 4.1.2. The laboratory certificate-of-analysis, chain-of-custody form and laboratory
data review for the sampling event are included in Appendix B.
4.1.1 Compliance Monitoring
As presented in Table 4, one NC Appendix I inorganic constituent was detected above the SWSLs and
applicable water quality standards in samples from groundwater monitoring wells during the April 2017
event. Cobalt was detected at concentrations above the SWSL and the Solid Waste Section
Groundwater Protection Standard (SWS GPS) in the samples from downgradient wells II-1 and II-3.
Cobalt was also detected at estimated concentrations below the SWSL, but above the SWS GPS in the
samples from wells II-5, II-8, and II-12. Vanadium was detected at estimated concentrations below the
SWSL, but above the SWS GPS in the samples from upgradient well MW-13 and downgradient wells II-3,
II-4A, II-5, II-6, II-7B, II-8, and II-12. The detections of cobalt and vanadium are considered naturally
occurring as determined in the November 2007 ASD; therefore, no further action is warranted. Thallium
was detected at estimated concentrations below the SWSL, but above the SWS GPS in the samples from
wells II-2, II-3, and II-5. Because these concentrations are below the SWSL and considered estimated,
no further action is warranted.
As presented in Table 4, four NC Appendix I VOCs were detected above their respective SWSLs and
applicable water quality standards in one or more downgradient wells during the April 2017 event.
Benzene was detected at a concentration above the SWSL and NC 2L Standard in the sample from well
II-3. Constituent 1,1-dichloroethane as detected at concentrations above the SWSL and NC 2L Standard
in the samples from well II-2 and II-3. Tetrachloroethene and vinyl chloride were detected at
August 2017 9 1668421.101
concentrations above their respective SWSLs and NC 2L Standards in the sample from well II-2. The NC
Appendix I VOCs were detected at a concentrations similar to previous events.
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 points SW-4 and SW-5. Lead was reported at an estimated concentration below
the SWSL, but above the Freshwater Chronic Standard at SW-3. Because the SWSL and surface water
standard exceedances were in an upstream sample, the exceedances do not appear to be 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.
4.1.2 Corrective Action Monitoring
As presented in Table 4, one NC Appendix I inorganic constituent was detected above the SWSLs and
applicable water quality standards in samples from groundwater monitoring wells during the April 2017
event. Cadmium was detected at a concentration above the SWSL and the SWS GPS in the sample from
well SMW-1. Cobalt was detected at estimated concentrations below the SWSL, but above the SWS
GPS in the samples from wells II-3B, II-9, SMW-1, and SMW-3. Vanadium was detected at estimated
concentrations below the SWSL, but above the SWS GPS in the samples from wells SMW-1, SMW-3,
and SMW-4. The detections of cadmium, cobalt, and vanadium are considered naturally occurring as
determined in the November 2007 ASD; therefore, no further action is warranted.
As presented in Table 4, no NC Appendix I VOCs were detected above their respective SWSLs and
applicable water quality standards in downgradient wells during the April 2017 event.
5.0 CONCLUSIONS
Analytical results from II-3 and II-3B continue to show that samples from well II-3B are more
representative of water quality at the compliance boundary than II-3, which is in close proximity to the
waste boundary. Well II-3B will continue to be monitored for the same parameter list as II-3.
Based on these results, the City of Greensboro will continue groundwater monitoring the Phase II landfill
in accordance with the requirements of the Assessment Monitoring and Corrective Action Programs, as
outlined in Title 15A NCAC 13B .1635 and .1637. Also, based on the results, the City of Greensboro will
continue the implementation of groundwater corrective action in accordance with the approved Corrective
Action Plan. The CAPER will be submitted prior to the second semi-annual water quality monitoring
event of 2017. The next semi-annual monitoring event is tentatively scheduled for October 2017.

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.
 Trip Blank II
o Acetone @ 18 ug/L (J) – add B flags to: MW-13
 7E02024-BLK1
o Copper @ 2.00 ug/L (J) – add B flags to: MW-13

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.

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.

 II-1
o Chloride @ DF = 10x o Sulfate as SO4 @ DF = 2x
o Total Alkalinity as CaCO3 = 5x

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.
 Cadmium (NC 2L = 2 ug/L; EPA MCL = 5 ug/L) o SMW-1 @ 8.65 ug/L

 Cobalt (GWPS = 1 ug/L)
o SMW-1 @ 2.39 ug/L (J) o SMW-3 @ 1.39 ug/L (J)
o II-3B @ 1.41 ug/L (J) o II-9 @ 2.71 ug/L (J)

 Vanadium (SWS GWPS = 0.3 ug/L)
o SMW-1 @ 12.4 ug/L (J) o SMW-3 @ 12.0 ug/L (J)
o SMW-4 @ 7.32 ug/L (J)
