RE: Water Quality Monitoring Report, 1st Semi-Annual 2016 Sampling Event Rowan County Active Landfill, Permit No. 80-03
789 Campbell Road, Woodleaf, Rowan County, North Carolina Dear Jackie:
On behalf of Rowan County Environmental Services (Rowan County), Golder Associates NC, Inc. (Golder) is submitting the enclosed Water Quality Monitoring Report, which documents the results of the January
12-14, 2016, compliance monitoring event. The facility consists of an active municipal solid waste (MSW)
landfill and a closed construction and demolition debris (C&D) landfill, each with a permitted monitoring network of wells and surface water locations. This report presents the results for both landfills.
As presented, one North Carolina (NC) Appendix I volatile organic constituent (VOC) was detected above
the Solid Waste Section Limit (SWSL) and applicable groundwater standard in the sample from the MW-28 at the MSW monitoring network during the January 2016 sampling. The source of this VOC is unknown
and has been detected during background sampling at the facility; it has not been detected recently in facility leachate samples. Landfill gas or historical site activities are potential VOC sources. As discussed
in our meeting on March 10, 2016, the County will proceed with preparing an Alternate Source Demonstration (ASD).
Two inorganic constituents (barium and cobalt) were detected at concentrations above their respective
groundwater standards in samples from MW-28 at the active MSW landfill. Based on the similar historical concentrations in upgradient and downgradient wells and statistical analysis, barium and cobalt are
interpreted to be naturally occurring and no further action is required.
Cobalt was detected at MW-1 and MW-20 at estimated concentrations below the SWSL but above the NC 2L standard during this event. Vanadium was detected at estimated concentrations below the SWSL and
above the groundwater standard at upgradient well MW-9 and downgradient monitoring points MW-12, MW-23A, MW-25, and the French drain during the January 2016 event. standard. In correspondence sent
to S&ME, Inc., dated September 12, 2008, the SWS approved an Alternate Source Demonstration (ASD) for vanadium as a naturally occurring metal. The concentrations of cobalt and vanadium are consistent
with historical background concentrations for this facility and are assumed to be naturally occurring. In conjunction with the ASD and based on these data, no further action is warranted.
Rowan County has monitored groundwater at its closed C&D landfill for parameters listed in Title 15A NCAC
13B.0544 of the NC Solid Waste Management Rules (NCSWMR). No Appendix I metals were detected at C&D wells at concentrations above SWSLs and applicable groundwater standards during this event. The
indicator parameter manganese was detected in samples from MW-18R at concentrations above the SWSL and above the groundwater standards during this event. Cobalt was detected in the sample from MW-18R
at an estimated concentration above the NC 2L but below the SWSL standard. Thallium was detected in the sample from MW-18R at an estimated concentration above the NC 2L but below the SWSL standard.
The concentrations of cobalt, manganese, and thallium are consistent with historical background

1.0 INTRODUCTION
This report summarizes the monitoring results from the January 12 - 14, 2016, water quality monitoring
event at the Rowan County Landfills located in Rowan County, North Carolina (NC) and operated under
the NC Solid Waste Permit No. 80-03. An active municipal solid waste (MSW) landfill, operated by Rowan
County Environmental Services, and a closed construction and demolition (C&D) landfill are located within
the property boundary. Rowan County (the County) has owned and operated the MSW and C&D landfill
under permit No. 80-03 since 1989. The C&D landfill located on site ceased accepting waste on June 30,
2008. The MSW landfill monitors water quality (i.e., groundwater, surface water, and leachate) semi-
annually in accordance with Title 15A of the North Carolina Administrative Code (NCAC) Subchapter 13B
.1632. The C&D landfill also monitors water quality (i.e., groundwater and surface water) semi-annually in
accordance with 15A NCAC 13B .0544.
1.1 Site Description and Background
The location of the facility is shown on the inlay on Drawing 1. As presented, the Rowan County solid waste
facility is located approximately 1.5 miles southeast of the town of Woodleaf on Campbell Road in Rowan
County, NC. The landfill facility covers approximately 355 acres of land and is bounded to the north by
Campbell Road, to the south by Second Creek, and to the east and west by wooded, residential and
agricultural properties. Surrounding land use is primarily rural residential, agricultural, or undeveloped and
wooded. Access to the facility is via a driveway off of Campbell Road. As discussed previously the facility
is comprised of an active Subtitle D MSW landfill unit and a closed C&D landfill unit (Drawing 1).
Topographic elevations at the facility range from approximately 766 feet above mean sea level (AMSL) east
of the existing scale house to approximately 635 feet AMSL at the edge of Second Creek along the southern
property boundary. Stormwater drainage from the landfill and surrounding areas is directed by one of the
two main drainage features toward Second Creek, which flows from the southwest to the northeast (S&ME
October 2005).
1.2 Compliance Monitoring History
Groundwater monitoring at the facility was initiated in December 1989 under the Detection Monitoring
Program for MSW landfills. Currently, water quality monitoring is performed semi-annually at the facility in
accordance with the approved Water Quality Monitoring Plan (WQMP) and the NC Solid Waste
Management Regulations (NCSWMR). The active MSW landfill monitoring network is currently comprised
of 15 active monitoring wells (MW-1, MW-7, MW-9, MW-11, MW-12, MW-13, MW-16, MW-20, MW-23,
MW-23A, MW-24R, MW-25, MW-26, MW-27, and MW-28), which monitor the uppermost aquifer beneath
the facility. Monitoring well MW-6 is monitored during each semi-annual sampling event for water levels
only. As part of the revised WQMP for the Phase IV landfill expansion, wells MW-25, MW-26, MW-27, and
MW-28 were added to the monitoring network, along with MW-27A, which is monitored for water levels
March 2016 2 063-6572015.100

only. Phase IV began operation on August 10, 2015; therefore, these wells were added to the compliance
monitoring network and detection monitoring will commenced during the most recent event (January 2016).
Three monitoring wells (i.e., MW-17, MW-18R, and MW-19) monitor the C&D landfill located to the east of
the active MSW landfill. The C&D wells are monitored for the parameters specified in 15A NCAC 13B .0544
of the NCSWMR. Monitoring wells MW-3, MW-4, MW-5, MW-10, MW-18, and MW-24 have been
decommissioned.
Five surface water locations (SW-1 through SW-5) are also sampled; SW-5 monitors surface water adjacent
to the C&D landfill, the other four surface water locations monitor surface water surrounding the active MSW
landfill. A French Drain is also sampled semi-annually to monitor a groundwater discharge point located
underneath the Phase III landfill unit at the active MSW landfill. The locations of monitoring points within
the current monitoring network are shown on Drawing 1.
1.3 Hydrogeologic Setting
Geologically, the facility is located within the Charlotte Belt of the Piedmont Physiographic Province of NC
(NCGS 1985). The Charlotte Belt is composed of Precambrian and Paleozoic bedrock, which is dominantly
plutonic with plutons ranging from granite to gabbro. The oldest rocks in the Charlotte Belt are mafic
gneisses, amphibolites, metagabbros and metavolcanic rocks, with lesser amounts of biotite gneiss, granitic
gneiss, mica schist, quartzite and ultramafic rocks. Mica schists and mica hornblende gneisses locally have
been intruded by granite. The rocks underlying the facility consist of mostly diorite, gabbro, and granite
(NCGS 1985).
The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of
partially weathered, fractured, meta-volcanic rock. Groundwater occurs at depths ranging from near ground
surface in valleys to more than 100 feet below grade on steep hills (S&ME October 2005). Depth-to-water
measurements obtained during the January 2016 monitoring event and summarized in Table 1 were used
to prepare a groundwater surface contour map presented as an overlay on Drawing 1.
As presented, groundwater in the uppermost aquifer beneath the facility generally flows to the southeast.
The groundwater surface contour map and interpreted flow directions are consistent with previously
submitted groundwater surface contour maps for this facility.
Based on the January 2016 groundwater surface contour map, the hydraulic gradient in the shallow aquifer
underlying the facility averaged 0.0331. The average effective porosity of the shallow aquifer is estimated
at 0.26 (S&ME October 2005).
Using the above values, the estimated rate of groundwater flow for the uppermost aquifer beneath the
facility was calculated using the following modified Darcy’s Law equation:
March 2016 3 063-6572015.100

Vgw = Ki/ne
where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic
gradient, and ne = effective porosity.
As presented on Table 2, the average estimated linear groundwater flow velocity under the waste
management units ranges from approximately 165 feet/year in the MSW area to approximately 460
feet/year in the C&D area, which is generally consistent with previous estimates. The linear velocity
equation above makes the simplified assumptions of a homogeneous and isotropic aquifer. Therefore, this
equation represents an estimated average value for the uppermost aquifer and does not account for
heterogeneous and/or anisotropic conditions that are likely present in the uppermost aquifer at the facility.
2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION
Field activities conducted as part of the January 2016 sampling event are discussed in the following
sections.
2.1 Visual Inspection Program
In order to determine if a potential release has occurred at the earliest possible time, the visual inspection
program is used by sampling personnel at the Rowan County landfills. 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 January 2016 compliance monitoring event, no physical indicators
were observed in the vicinity of the waste management areas.
2.2 Well Network and Groundwater Elevation Measurements
As presented in Section 1.3 of this report, the current groundwater monitoring network at the Rowan County
landfills (i.e., the active MSW and the closed C&D landfill) consists of 18 groundwater monitoring wells (i.e.,
15 monitor groundwater at the MSW landfill and 3 monitor groundwater at the C&D landfill). Monitoring
well construction information is summarized in Table 3 and the well locations are shown on Drawing 1. The
network of monitoring wells was constructed to target the preferential flow path for groundwater underlying
waste disposal areas.
Water quality was monitored during the January 2016 water quality monitoring event (WQME) in
accordance with the revised WQMP, which was approved by NCDENR as part of the Phase IV expansion
at the active MSW landfill in March 2013. Based on the WQMP monitoring wells MW-9 and MW-16 are the
MSW landfill’s background wells and are located hydraulically upgradient of the waste disposal area.
Monitoring wells MW-1, MW-7, MW-11, MW-12, MW-13, MW-20, MW-23, MW-23A, MW-24R, MW-25,
MW-26, MW-27, and MW-28 are located downgradient or side gradient of the waste disposal area and
March 2016 4 063-6572015.100

represent the facility’s downgradient compliance wells. The C&D unit is monitored by upgradient well
MW-17 and downgradient compliance wells MW-18R and MW-19.
Depth-to-water measurements were recorded to the nearest 0.01 foot prior to initiating groundwater purging
and sampling activities. The monitoring point summary and respective water level elevations for this event
along with historical data are presented in Table 1.
2.3 January 2016 Groundwater and Surface Water Monitoring Event
Personnel from Golder visited the facility on January 12 - 14, 2016 to purge and sample the 18 groundwater
monitoring wells. Samples were also collected for 5 surface water monitoring points and the facility’s
leachate pond. Depth-to-water measurements were obtained from the network monitoring the wells to the
nearest 0.01 foot using an electronic water level indicator prior to purging the wells.
The 18 groundwater monitoring wells were purged and sampled using dedicated bladder pumps and micro-
purge procedures. Measurements of pH, specific conductivity, dissolved oxygen (DO), oxidation-reduction
potential (ORP), temperature, turbidity, and depth-to-water were recorded each time the flow-cell volume
was replaced 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 water, up to a maximum
purge rate of 500 milliliters per minute. Purging was continued until stabilization was indicated by the field
parameters. Due to low well volume in MW-20, a disposable bailer was used to purge and sample the well;
the well was purged to dryness and allowed to recover prior to sampling.
Prior to sampling, the laboratory-supplied sample containers used to collect the water samples detailed
above 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 micro-purge groundwater samples were collected directly from the dedicated bladder pump discharge
lines in the labeled, laboratory-supplied, pre-preserved sample containers after purging was completed
based on stabilization of the field parameters. After collection, the sample containers were placed in a
cooler on ice, under chain-of-custody control. Copies of the sampling logs detailing the sample ID, the
personnel collecting the samples, the sampling location, the sampling equipment, the sampling method,
general field observations, and field parameters are presented in Appendix A.
The water sample collected from the French Drain was collected using a stainless steel dipper, by lowering
the dipper directly into the flowing water (located inside the drain), removing the dipper of water, and pouring
water sample into a labeled, laboratory-supplied, pre-preserved sample container. After collection, the
water samples are placed in a cooler on ice, under chain-of-custody control. A copy of the French Drain
sampling log is also presented in Appendix I. Measurements of pH, specific conductivity, temperature, and
turbidity are recorded at the time of sampling.
March 2016 5 063-6572015.100

When possible, the surface water samples collected were collected by lowering the sample containers
directly into the stream flow with the container opening facing away from the stream flow, taking care to
prevent the overflow of the sample containers and to minimize sample induced turbidity. If necessary (i.e.,
if access to the sample point was limited) a stainless steel dipper was lowered into the stream flow and
filled. The water sample collected in the dipper was then transferred directly to the provided appropriate
sample containers.
The leachate samples were collected directly from the leachate pond using a disposable bailer. After the
leachate sample was collected in a disposable bailer the sample was again transferred directly to the
provided sample containers. Measurements of pH, conductivity, temperature, turbidity, DO, and ORP were
recorded during the collection of the surface water samples directly from the point of sampling, and
measurements of pH, specific conductivity, and temperature were recorded for the leachate sample from a
separate sampling container.
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 I. Included in each log is a description of the sample ID, sampling
personnel, sampling equipment, sampling location, sampling method, field observations, and water-quality
measurements.
2.4 Laboratory Analysis Program
The groundwater, surface water, and leachate samples collected on January 12 - 14, 2016, from the active
MSW landfill were delivered by courier to Environmental Conservation Laboratories, Inc. (ENCO) of Cary,
NC under chain-of-custody control for analysis of NC Appendix I constituents. Groundwater samples
collected from the closed C&D landfill were analyzed for the listed NC Appendix I constituents and the
additional required C&D parameters under NCAC 13B.0544. Groundwater samples collected from the C&D
monitoring wells and surface water sample, SW-5, were also analyzed for tetrahydrofuran, per recent Solid
Waste Section (SWS) policy requirements. The samples were received at the laboratory on February 2,
2016 in good condition and properly preserved.
2.5 January 2016 Sampling Results
Analytical results for the January 2016 groundwater, surface water, and leachate samples are summarized
in Tables 4, 5, 6, 7, 8, 9, and 10 with available historical data. The laboratory certificates-of-analysis, chain-
of-custody form, and laboratory data reviews for the sampling event are included in Appendix II of this
report.
As presented in Table 4 and the laboratory certificates-of-analysis, two NC Appendix I volatile organic
constituents (VOCs) – tetrachloroethene and trichlorofluromethane - were detected at concentrations above
the Solid Waste Section Limits (SWSLs) in groundwater samples collected from MW-28 at the active MSW
landfill monitoring network during the January 2016 water quality monitoring event. Three inorganic
March 2016 6 063-6572015.100

constituents (barium, cobalt, and zinc) were detected at concentrations above their respective SWSLs in
samples from one or more compliance monitoring points during the January 2016 monitoring event. The
results of the January 2016 sampling event are generally consistent with historical results for this facility
and are summarized in Table 4.
No NC Appendix I VOCs were detected at concentrations above their respective SWSLs in groundwater
samples collected from the C&D landfill monitoring network during the January 2016 water quality
monitoring event. Barium was detected in one or more downgradient samples above the SWSL during this
event, as it has been during previous events. Several indicator parameters including iron and manganese
were detected in samples from C&D monitoring wells at concentrations above the SWSLs during this
monitoring event as they have been previous sampling events.
Zinc was detected at SW-3 during this event as it has been during previous sampling events. No other NC
Appendix I constituents were detected in surface water samples at concentrations above SWSLs during
this event. The January 2016 leachate results were generally consistent with historical results for this facility
and are summarized in Table 8.
3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the January 2016 groundwater sampling event.
In addition to the field blank, a laboratory-prepared trip blank accompanied the VOC sample containers for
the sampling event to and from the laboratory. ENCO analyzed the field blank for the same constituents
as the groundwater samples, and the trip blank for NC Appendix I VOCs. A review of the laboratory data
was performed by Golder personnel (included in Appendix II). Three NC Appendix I inorganic constituents
(antimony, barium, and copper) were detected in the field blank at estimated concentrations. Based on
concentrations detected in blanks and samples, the antimony concentrations in the samples from MW-1,
MW-7, MW-9, MW-11, MW-12, MW-17, MW-18R, MW-27, and SW-3, as well as the copper concentrations
from MW-28 and SW-3 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
The NC Appendix I organic constituent, tetrachloroethene, was detected in the sample from monitoring well
MW-28 at a concentration that exceeded the SWSL and the NC 2L Standard during this monitoring event.
Based on available data, the source of the tetracholorethene is unknown but it has not been recently
detected in facility leachate samples. Barium and cobalt were detected at MW-28 at concentrations
exceeding the SWSLs and respective groundwater standards. As described below, these concentrations
were statistically determined to be below background concentrations and no further action is warranted.
March 2016 7 063-6572015.100

Vanadium was detected in the sample from upgradient well MW-9 at a concentration exceeding the NC 2L
Standard. No further action is required for this upgradient monitoring point. Cobalt (MW-1 and MW-20) and
vanadium (MW-9, MW-12, MW-23A, MW-25, and French Drain) were detected at estimated concentrations
below the SWSLs but above the groundwater standards during this event. Concentrations are similar to
historical data and estimated; therefore, no further action is warranted.

The indicator parameter manganese was detected above the SWSL, but above the NC 2L Standard in the
sample from downgradient monitoring well MW-18R at the closed C&D landfill. Cobalt and thallium were
also detected at concentrations below the SWSLs but above the groundwater standards during this event.
The concentrations of cobalt, manganese, and thallium are consistent with historical background
concentrations for this facility and are assumed to be naturally occurring; therefore, no further action is
warranted.
5.0 CONCLUSIONS
Based on the results summarized herein, Rowan County Environmental Services will continue monitoring
the uppermost aquifer beneath this facility in accordance with the requirements of the Compliance
Monitoring Program as outlined in Title 15A NCAC 13B .1634 at the MSW landfill and Title 15A NCAC
13B.0544 at the C&D landfill. As discussed in our meeting on March 10, 2016, the County will proceed
with an ASD to address the VOCs issues at MW-28. The next compliance monitoring event for this facility
is tentatively scheduled for July 2016.

TM 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.

• Field Blank
• Antimony @ 0.577 ug/L (J) Add B-Flags to: MW-1, MW-7, MW-9, MW-11, MW-12, MW-27, SW-3

TM 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.

TM The report provides the reporting limit for each constituent.

TM The results were reported at or below their proper reporting limits (e.g., MDLs, MRLs,
PQLs, etc.). 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.

TM No inorganic and organic constituents were reported above their respective NC 2L Drinking
Water Standards in wells, surface points, or field/equipment/trip blanks.

LABORATORY DATA REVIEW
Page 3 of 3
TM 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.

• MW-18R Sulfate x2

TM The report provides the reporting limit for each constituent.

TM The results were reported at or below their proper reporting limits (e.g., MDLs, MRLs,
PQLs, etc.). 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.

TM No inorganic and organic constituents were reported above their respective NC 2L Drinking
Water Standards in wells, surface points, or field/equipment/trip blanks.

• MW-18R:
o Cobalt @ 1.61 J ug/L (NC 2L =1 ug/L)
o Manganese @ 690 ug/L (NC 2L = 50 ug/L)
o Thallium @ .309 ug/L (J) (NC 2L = 0.28 ug/L)

TM For sites with historical data, no inorganic and organic constituents were detected in a well
or surface water point at concentrations outside of their historical range (more than 5X
previous concentrations or first-time detections).

TM Laboratory blank is interference-free.

TM Surrogate recoveries are provided for each analytical method, where applicable.

TM Surrogate recoveries for each method are within the acceptable limits (i.e., at least
50% of the surrogates were within range).

• The Spike recoveries of Phosphorous and Sulfate were outside of control limits for the MS
and/or MSD samples, and the precision between duplicate spikes of Phosphorous exceeded
acceptance criteria. The QC batches were approved based on acceptable LCS recovery of
these analytes.

TM MS/MSD/LCS data results are provided for each analytical method.

TM MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at least 1 of
the 3 were within range).

5.0 DATA REPORTING

TM All analytical reporting associated with the event was performed by the contracted lab.

TM 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.

• Field Blank
• Antimony @ 0.577 ug/L (J)
• Barium @ 1.94 ug/L (J)
