Subject: April 2019 Semi -Annual Groundwater Sampling Report
North Wake Closed Unlined Landfill
Facility Permit No. 9209-MSWLF-1984
Dear Ms. Drummond:
CDM Smith Inc., on behalf of Wake County (County), is submitting an electronic copy of the April 2019
semi-annual sampling event report. This letter report presents the results of the semi-annual sampling
event that was recently completed at the North Wake Closed Unlined Landfill and constitutes the first
semi-annual sampling event for 2019. The groundwater monitoring network consists of the following
wells: MW-11 (shallow background well), -11d (deep background well), -5R, -6, -6d, -7, -8, -8d, -9, -10,
-10d, -22, -23, -23d, -24, -28, -28d, -29d, -30, -31, -31d, -32, -33, -34, -34d, -35, -36, -36d, TB-1a, TB-1a
deep and surface water sampling locations: SW-2, -3, -7, and -8. Field activities, sampling results for all
wells and surface water locations, an evaluation of the groundwater corrective action effectiveness,
and recommendations are discussed below.
Field Activities
Groundwater and surface water samples from the North Wake Closed Unlined Landfill were collected
on April 22-25, 2019. Monitoring well and surface water sample locations are shown on Figure 1.
Construction details for each monitoring well are summarized in Table 1.
Samples were collected from the monitoring wells by use of a peristaltic pump or disposable,
laboratory decontaminated bailers. Groundwater elevations were measured at each well prior to
sampling using an electronic water level indicator with an accuracy of 0.01 feet and are presented in
Table 1. These groundwater elevations were used to construct potentiometric contours for this
sampling event and are shown on Figure 1. The groundwater elevations and potentiometric contours
were also used to estimate groundwater velocities at each well as presented in Table 2.
After depth to groundwater was measured, three well volumes of water were removed from each
well prior to sampling to provide fresh formation water within the well water column. Each well

volume and surface water sample was measured for pH, conductivity, temperature, turbidity,
dissolved oxygen (DO), and oxidation-reduction potential (ORP) using a YSI-556 multi -parameter
water quality meter and a HANNA HI 98703 turbidity meter. Wells that had elevated turbidity were
allowed to stabilize prior to sample collection. The water quality measurements at the time of sample
collection are provided in Table 3.
Sampling Results
All groundwater and surface water samples were analyzed for North Carolina Appendix I volatile
organic compounds (VOCs) plus dichlorodifluoromethane and 1,4-dioxane, and Appendix I metals plus
mercury. Samples from monitoring wells MW-5R, -6, -8, -9, -10, -11, and -36 were analyzed for natural
attenuation parameters per the Corrective Action Plan (CAP) that was approved by the North Carolina
Department of Environmental Quality (NCDEQ) - Solid Waste Section (SWS) in March 2010. The
groundwater and surface water samples were analyzed by Shealy Environmental Services, Inc. located
in West Columbia, South Carolina. Monitoring wells MW-22, -24, -30, -31, and TB-1a were not
sampled during the April 2019 sampling event due to the low volume of groundwater in the wells.
The analytical results were reported to the laboratory specific method detection limit (MDL) and are
quantifiable at or below the laboratory limit of quantitation (LOQ). All monitoring wells for the North
Wake Unlined Landfill had detections of analytes above the MDL but below the LOQs and were
qualified as estimated or "J" flags.
The following list summarizes which analytes were detected above the LOQ at each sample location.
Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Quality Standard,
Interim Maximum Allowable Concentration (IMAC), or the 15A NCAC 02B (NC 213) or North Carolina
Protective Value Surface Water Quality Standard for Class C Waters. No "J" flag detections are listed.
A complete summary of all detected and estimated concentrations from the March 2011 through the
April 2019 sampling events is presented in Table 4. Laboratory data reports are provided in Appendix

"J" flags were not included in the previous list, but several locations had "J" flag detections that
exceeded the standards. The "J" flag constituents above the standards along with their locations are
listed below.
Cobalt: MW-11, -8, -10, -23, -28, -34, and -35
Thallium: MW-36
Vanadium: MW-11, -6d, -8, -8d, -9, -23, -23d, -28, -28d, -31d, -32, -33, -34, -35,
-36d, and TB-1a deep
It is likely that the recent and historic detections of chloroform in wells MW-6d, -24, -31d, and TB-1a
deep are attributed to a release from a municipal water line in the Falls River development and are
not related to a release from the landfill.
In a letter dated March 22, 2012, the SWS approved the County's request to discontinue collecting
samples from select wells for herbicide and pesticide analyses during the semi-annual spring sampling
event. However, the SWS requested that MW-29d continue to be sampled for bis(2-ethylhexyl)
phthalate during spring sampling events due to a detection from the March 2011 event.
Bis(2-ethylhexyl) phthalate was detected above the NC 2L Standard (3 parts per billion (ppb)) at 28.5
ppb in samples collected from MW-29d during the April 2014 sampling event. A confirmatory sample
collected from MW-29d during the November 2014 sampling event had an estimated detection of
bis(2-ethylhexyl) phthalate at 4.61 ppb, which is above the NC 2L Standard. Bis(2-ethylhexyl)
phthalate has not been detected above the laboratory MDL in samples collected from MW-29d since
the November 2014 sampling event, except for J flag detections below the NC 2L Standard in samples

collected during the April and October 2018 events. The concentration trend for bis(2-ethylhexyl)
phthalate in MW-29d will continue to be evaluated.
Equipment and trip blanks were analyzed for quality control. A duplicate sample was also collected for
quality control. Acetone was detected as an estimated concentration below its NC 2L Standard in the
equipment blank. Three trip blanks were analyzed for VOCs and had no detections above the MDL.
The duplicate sample, identified as DUP, was collected from MW-8 and had similar analyte
concentrations as those detected in MW-8 with the exceptions of estimated detections of chromium
and mercury below their respective NC 2L Standards in the parent sample. Table 5 presents a
summary of all analytes detected during the April 2019 sampling event that exceeded the NC 2L or
IMAC Standards.
As part of an ongoing Alternate Source Demonstration for the landfill, filtered samples were collected
from monitoring wells MW-11, -23, -28, -28d, -32, -34, and -36 during the April 2019 sampling event
due to elevated turbidity (i.e. greater than 10 Nephelometric Turbidity Units). These samples were
collected to demonstrate that select metals exceeding the NC 2L or IMAC Standards are naturally
occurring and not related to a release from the landfill. Total metals that exceeded the NC 2L or IMAC
Standards from these wells were analyzed for dissolved metals to determine if turbidity was a
contributing factor to total reported metals.
Based on qualitative and quantitative evaluation of current and historic groundwater sampling data,
the NC 2L or IMAC Standard metal exceedances from the April 2019 sampling event were determined
to be indicative of naturally occurring background concentrations as opposed to a release from the
landfill. Below is a summary of the dissolved metals exceedances. Wells with a "*' qualifier had a "J"
flag detection for that analyte. Dissolved metal sample results are provided in Table 4 and the
laboratory data report is provided in Appendix A.

Vanadium: MW-28* and -28d*
Corrective Action Effectiveness Evaluation
The SWS expressed concern in May 2008 that VOCs may be migrating beyond the landfill property
boundary and into Abbott's Creek based on detections above the NC 2L Standard in monitoring well
MW-9. As a result, the SWS directed the County to install and sample groundwater monitoring wells,
one shallow and one deep (i.e. MW-36 and -36d), downgradient of MW-9 to determine if VOCs may
be migrating beyond the landfill property boundary, possibly discharging into Abbott's Creek. Initial
groundwater samples collected from MW-36 and -36d in December 2008 had detections of VOCs
above NC 2L Standards.

Surface water sample locations SW-7 and -8, located on Abbott's Creek, were added to the semi-
annual monitoring program in November 2008. Samples collected from SW-7 and -8 since being
added to the monitoring program have never had VOCs detected above the NC 2B Surface Water
Quality Standards.
An Assessment of Corrective Measures Report was submitted to the SWS in accordance with the
North Carolina Solid Waste Management Rule 15 NCAC 13B .1635 and approved in December 2009.
The SWS approved the selected remedy of monitored natural attenuation paired with in situ
remediation by air sparging to address groundwater contamination at the facility. A pilot test was
conducted in July and August 2010 near MW-6 and -6d to evaluate the effectiveness of the air
sparging remedy and to collect data for the full-scale system design in accordance with the CAP. The
pilot test successfully reduced the concentrations of 1,1-dichloroethane and vinyl chloride to below
their respective NC 2L Standard in MW-6d and vinyl chloride was not detected in samples collected
from MW-6 during the October 2010 semi-annual sampling event.
The full-scale system was installed in October 2011 and was operational in August 2012. The air
sparging system consists of 15 shallow wells screened across saturated saprolite and partially
weathered rock and 14 wells screened in the shallow fractured bedrock. In addition to the air sparging
wells, the system also consists of an air compressor and control panel that are housed in a secured
on -site control building. Routine inspections are performed on the system and a Field Inspection Log
completed during each inspection is kept on file at the facility.
The County installed a vacuum extraction system around the perimeter of the landfill in January 2002
to prevent offsite migration of soil gas. The air sparging system was designed to work in tandem with
the existing perimeter migration control system (PMCS) by recovering air and gas vapors produced by
the air sparging system. Since previous work has indicated a relationship between the soil gas and the
contaminated groundwater, the installation of the PMCS is likely to further reduce groundwater
contaminant concentrations. As discussed in the approved CAP, the vacuum extraction system will be
used in conjunction with the air sparging system to reduce VOCs in the bedrock and partially
weathered rock between MW-9 and the MW-6 nested pair.
As part of the corrective action effectiveness evaluation, contaminant concentration trends for
monitoring wells MW-6, -6d, -9, -36, and -36d were evaluated. Total VOC concentration trends for
each well are presented on Figures 2 through 6. Trend results for each well are discussed below.
Figure 2 presents a total VOC concentration trend analysis for samples collected from MW-6. VOCs in
MW-6 significantly decreased after January 2002 when the PMCS was operational and were not
detected from November 2004 to April 2007. The total VOC concentration in MW-6 increased in May
2008 to 24 ppb compared to the November 2007 concentration of 14 ppb. The total VOC
concentration in MW-6 has shown a decreasing trend since the May 2008 sampling event with the

exception of an increase in total VOCs in samples collected during the October 2018 sampling event
that is related to the introduction of the 1,4-dioxane analysis. The concentration of 1,4-dioxane in
samples collected from MW-6 during the October 2018 sampling event was 26 ppb. 1,4-Dioxane was
detected in samples collected from MW-6 during the April 2019 sampling event at a concentration of
4.9 ppb.
Vinyl chloride has not been detected above the laboratory MDL in MW-6 since the April 2013
sampling event. Benzene detections in MW-6, which historically have exceeded the NC 2L Standard,
have been below the laboratory MDL since April 2013 with the exception of the November 2014
sampling when it was detected (1.1 ppb) slightly above the standard and October 2018 when it was
detected above the MDL at 0.61 ppb.
The trend analysis for total VOC concentrations in MW-6d is presented on Figure 3. VOCs were not
detected at MW-6d from December 2001 through November 2007. The increase in total VOCs from
samples collected during the May 2008 sampling event is a result of reporting "J" flag detections as
required by the SWS. VOC concentrations in MW-6d have been below the NC 2L Standards since the
March 2011 sampling event.
Figure 4 presents a total VOC concentration trend analysis for samples collected from MW-9.
Historically, MW-9 has had the highest concentration of VOCs compared to the other landfill
monitoring wells. VOCs were not detected above the NC 2L Standards in MW-9 from October 2012
through April 2015. There was a "J" flag detection above the NC 2L Standard of 1,2-dichloroethane in
samples collected from MW-9 during the October 2015 sampling event and a detection of vinyl
chloride (1.0 ppb) above the NC 2L Standard in samples collected during the April 2016 sampling
event. Benzene and vinyl chloride were detected above their respective NC 2L Standard in samples
collected during the April 2019 sampling event. Total VOC concentrations in MW-9 show a decreasing
trend.
Trend analyses for total VOC concentrations in MW-36 and -36d are presented on Figures 5 and 6,
respectively. VOC concentrations in MW-36 have been below the NC 2L Standards since the April 2012
sampling event and have shown a decreasing trend since the air sparging system has been
operational. No VOCs have been detected above the NC 2L Standards in MW-36d since the October
2015 sampling event. Total VOC concentrations in both monitoring wells will continue to be
monitored and are expected to decrease while the air sparging system is operational.
Additional groundwater samples were collected from MW-5R, -6, -8, -9, -10, -11, and -36 for
evaluation of monitored natural attenuation as part of the corrective action program as required by
SWS guidelines. These parameters include biochemical oxygen demand, chemical oxygen demand,
alkalinity, nitrate, chloride, sulfate, sulfide, total organic carbon, carbon dioxide, methane, ethane,
ethene, ferrous iron, volatile fatty acids, dissolved hydrogen, and field measurements of pH,

temperature, conductivity, ORP and DO. Geochemical results are presented in Table 6. The laboratory
data for the additional parameters is included in Appendix A.
As discussed in the approved CAP, concentrations of some of the natural attenuation data from select
wells indicates that environments are present which favor reductive dechlorination; notably, the
concentrations of nitrate, ferrous iron, sulfate, and carbon dioxide. The following evidence indicates
that one or more mechanisms of natural attenuation and/or reductive dechlorination may be
occurring at the site:
• VOC concentrations in contaminated wells continue to decline;
• The ratio of parent to daughter compounds continues to decrease over time;
• Nitrate, ferrous iron, sulfate, and carbon dioxide continue to be detected at concentrations
favoring reductive dechlorination; and
• Concentrations of cis-1,2-dichloroethene continue to be greater than dichloroethene isomers
trans 1,2-dichloroethene and 1,1-dichloroethene.
VOCs that exceed the NC 2L Standards, including benzene, 1,4-dichlorobenzene, 1,1-dichloroethane,
methylene chloride, tetrachloroethene, trichloroethene, and vinyl chloride, have been detected in the
area of MW-5R, -34, and -34d. MW-5R is located near the landfill property line and the MW-34 cluster
is located west of MW-5R on the adjacent parcel. The VOC exceedances are likely from the migration
of leachate from the landfill into the surficial aquifer. These wells are located more than 900 feet
away from the air sparging system, which has proven to reduce VOC concentrations in groundwater at
the landfill, so in situ enhanced anaerobic bioremediation (EAB) is the proposed remedy to reduce
total VOC concentrations at the property line. CDM Smith will submit a CAP Addendum to the SWS for
approval prior to implementing the remedy.
Recommendations
The CAP Addendum that will be submitted to the SWS will discuss the reduction of total VOCs by an
EAB injection of sodium lactate and emulsified vegetable oil (EVO) solutions upgradient of MW-5R,
-34, and -34d. Sodium lactate and EVO enhance biologically reducing conditions that favor and
support dechlorination of VOCs to non -toxic end products. Eight injection wells will be installed
approximately 20 feet apart to the top of bedrock to support the injection. A geochemical evaluation
will be performed to determine if pH buffering by sodium bicarbonate is necessary to support the
EAB. The initial injection will include sodium lactate and sodium bicarbonate (if necessary) to provide
the existing microbial community with an initial source of carbon and energy. After the first injection,
EVO and sodium bicarbonate (if necessary) will be injected to provide the microbial community with a
source of carbon for up to five years. An Underground Injection Control (UIC) Permit will be submitted
to the NCDEQ— Groundwater Protection Section prior to implementing the remedy. The CAP
iD

Addendum and UIC Permit are estimated to be submitted in June 2019. Remedial activities are
anticipated to begin in the fall of 2019.
The County will continue with the semi-annual assessment monitoring program. In addition to
sampling for Appendix I metals plus mercury, Appendix I VOCs plus dichlorodifluoromethane and 1,4-
dioxane, and the Appendix II constituent, bis(2-ethylhexyl) phthalate (sampled at MW-29d only during
the spring sampling event), samples collected from MW-5R, -6, -8, -9, -10, -11, and -36 will continue to
be analyzed for natural attenuation parameters during the semi-annual events. The air sparging
system will continue to operate and the effectiveness of the system will be re-evaluated after the next
semi-annual sampling event in the fall of 2019. The effectiveness of the EAB injection will also be
evaluated following remedial activities with quarterly sampling of MW-5R, -34, and -34d beginning
two months after the EVO injection. Following the fourth quarterly post -injection sampling event,
sampling of these wells will return to semi-annually.

Notes:
1. All units are in micrograms per liter (parts per billion).
2. * - Interim Maximum Allowable Concentration (IMAC)
3. dup - Duplicate Sample
4. (4) - Monitoring wells MW-22, -24, -30, -31, and TB -la were not sampled during the April 2019 sampling events due to insufficient volumes of water in the wells.
5. J - Indicates the analytical result is an estimated concentration between the method detection limit and the limit of quantitation.
6. B - The analyte concentration detected in the method blank was greater than the method detection limit.
7. Monitoring wells MW-28, -28d, -33, -34, -34d, and -35 are sampled yearly during the spring event.
8. Dissolved metal samples were collected to evaluate the influence of turbidity on total metal concentrations as part of an ongoing Alternate Source Demonstration.
9. NA - Not Analyzed
Concentration exceeds the 15A NCAC 02L .0202 (North Carolina 2L) or IMAC Standard.
Indicates the result is below the detection limit.

3. CaCO3 - Calcium Carbonate
4. MW-11 is a background well for the North Wake Unlined Landfill.
S. * - Field analysis performed using a HACH kit.
6. J - Indicates the analytical result is an estimated concentration between the method detection limit and the limit of quantitation.
7. B - The analyte concentration detected in the method blank was greater than the method detection limit.
8. D -Analyzed at dilution.
9. UX -The compound was analyzed for, but not detected. 1 mL HNO3 was added to MW-6 for metals upon receipt to get the pH to <2.
10. (1) - BOD was measured following dilution and did not meet the oxygen depletion criterion of at least 2 mg/L. The elevated BOD concentrations are a result of laboratory error and were not used to evaluate natural
attenuation for the April and November 2014 sampling events.
11. 1- The average BOD for MW-9, -10, -36, and -11 is lower than the valid range.
12. (-) Samples not collected and analyzed for the fall 2016 sampling event.

Case Narrative
CDM Smith
Lot Number: UD23018
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved NELAC standards, the Shealy Environmental Services, Inc. ("Shealy") Quality
Assurance Management Plan (QAMP), standard operating procedures (SOPS), and Shealy policies. Any
exceptions to the NELAC standards, the QAMP, SOPS or policies are qualified on the results page or
discussed below.
VOA 8260D
The continuing calibration verification (CCV) associated with samples UD23018-001(MW-5R) , UD23018-
002 (MW-6), UD23018-003 (MW-8), and UD23018-004 (DUP) for analytes: Acetone and 2-Butanone
recovered above the upper control limit. The LCS failed high for Acetone as well. The samples
associated with this CCV and LCS were non -detect for the affected analytes; therefore, the data has been
reported.
BOD
For sample UD23018-003 (MW-8), no sample dilutions resulted in a depletion of at least 2.0 mg/L. The
reported BOD/CBOD value is non- detect, which was computed using the lowest BOD/CBOD value that
can be calculated with the available data. COD approximate values were used to determine sample
dilutions. The data have been flagged with a "6" to reference this issue.
The results of the three GGA check samples associated with the batch that includes samples UD23018-
016 (MW-9), UD23018-017 (MW-10), UD23018-021 (MW-36) and UD23018-024 (MW-11) are as follows:
83.1 mg/L, 148.6 mg/L, and 190.1 mg/L. The resulting average BOD for the three bottles, after correcting
for dilution and seed is 140.2 mg/L which is lower than the method required range of 198±30.5 mg/L. The
affected data has been flagged accordingly with a "1 ".
Dissolved gases (MEE RSK175)
The following samples had an air bubble > 6mm at analysis time in the sample vial: UD23018-002 (MW-
6), UD23018-016 (MW-9),and UD23018-017 (MW-10).

Subject: RE: North Wake Unlined LF
Thanks Joseph!
They have a new person in the field collecting the samples and we have a new sample receiving
person.
I did not know that they did not apply the dissolved hydrogen labels to the individual vials here
after sample receipt in the LIMS. You can tell which sample ID is which —correct? If so, go ahead
with analysis and put a note in the narrative of the report concerning the MW-8 vials not having
the collection date and time from the field.
Let me know if you need anything else.
Have a great day!

Upon receiving your samples for the project referenced above, The hydrogen vials all of the labels were on
the bubble wrap not on the vials themselves we did apply them, Sample MW-8 (BAK Vials) no date and time
of collection on the vials.
