Re: Semi -Annual Water Quality Monitoring Report with Corrective Action Update
Alexander County Active C&D and Closed MSWLF
Permit No. 02-01
MESCO Project No. G18003.0
Event Date: December 27-29, 2018
Introduction
On behalf of Alexander County, Municipal Engineering Services Company, P.A. (MESCO) is pleased to
present this Semi -Annual Water Quality Monitoring Report with Corrective Action Update for an
event performed at the Alexander County active construction and demolition (C&D) and closed municipal
solid waste landfill (MSWLF) on December 27-29, 2018. NCDENR Solid Waste Rules 15A NCAC
13B.1632 requires that Alexander County provide this report to the NC Solid Waste Section (SWS) on a
semi-annual basis. Laboratory analytical results indicate that samples collected from 12 wells contained
up to three metals above regulatory compliance Standards. Metal detections are believed to be naturally
occurring. One or two volatile organic compounds (VOCs) were detected at levels above the 2L Standard
in samples collected from 8 wells. The source of VOCs is likely anthropogenic. VOC concentrations
continue to decrease over time and distance. A few surface water samples contained elevated levels of
metals which are not believed to have originated from a release. Corrective action to remediate VOCs in
groundwater is ongoing within the four areas of concern (AOC) with updated information presented herein.
A Corrective Action Evaluation Report (CAER) (DIN:27584) dated April 3, 2017 concluded groundwater
quality has improved. The SWS approved that corrective action may continue as proposed and the
contingency plan is not required to be implemented.
Background
The Alexander County active C&D and closed MSWLF, is located at 2500 Paynes Dairy Road near
Taylorsville North Carolina. The total waste footprint encompasses approximately 24 acres situated on 283
contiguous acres. The site location topographic map is depicted in the attached Sheet 1.
The closed MSWLF ceased operation prior to 1998 and the C&D landfill continues operation on the eastern
unit of the closed MSWLF. Both landfill areas are treated as a single unit in this report. Water quality has
been monitored at this facility on at least a semi-annual basis since 1990. MESCO submitted two
Assessment and Corrective Action (ACM) reports dated August 27, 2002 and April 11, 2008. MESCO
then developed a Corrective Action Plan -Revision 1 (CAP -Rev 1) on February 6, 2009. In response to
improved water quality and changing geochemical conditions the originally selected remediation approach
was amended by MESCO in a Corrective Action Plan -Addendum (CAP -Add) dated December 20, 2010.
Groundwater remediation efforts have been implemented at the four distinct areas of concern (AOCs) which
are identified as MW-113, MW-16, MW-24 and MW-26. Remediation technologies initiated to date with
reference to their respective AOC include monitored natural attenuation (MNA) (MW-16, MW-24, MW-
26), phytoremediation (MW-24), enhanced bioremediation via substrate injection (MW-26) and landfill gas
(LFG) extraction (MW-1B).

LICENSE NUMBER: C-0281

Following establishment of the two-year MNA baseline MESCO completed a CAER (DIN 13596) on
March 22, 2011. Based on improved water quality conditions as demonstrated in the CAER the parameters
and frequencies of future monitoring events were established by the SWS CAER review response (DIN
14150) dated June 16, 2011.
A second CAP -Add was submitted by MESCO dated May 30, 2013 as requested by the SWS in a letter
entitled Compliance Boundary (Relevant Point of Compliance) (DIN 18502) dated February 18, 2013. A
Request for Appendix II Groundwater Monitoring Modification (DIN 20137) was submitted by MESCO
dated November 8, 2013 which was subsequently approved by the SWS (DIN 20144) on November 13,
2013. A second CAER (DIN:27584) dated April 3, 2017 concluded that attenuation is occurring and no
corrective actions other than what has already been initiated are planned at this time as approved by the NC
SWS (DIN:27678).
As specified within 15A NCAC 13B.16320), the SWS Environmental Monitoring Report Form and SWS
memorandums this report contains sampling procedures, field and laboratory results, corrective action
update, ground/surface water characterization, and findings. Well construction summary table, field
observations table, field parameter data table, sampling and analysis summary table, detections compared
to Standards tables, a groundwater flow directions/rates table, potentiometric map, time -series graph,
quality assurance/quality control data, and laboratory analytical data results are enclosed herein.
Sampling Procedures
MESCO personnel performed this sampling event following the parameters and frequency established in
the Water Quality Monitoring Plan (WQMP) dated August 11, 2016. The water quality monitoring program
includes a combination of detection, assessment and corrective action monitoring with specifically defined
analysis.
Water samples were collected from all monitoring locations outlined in the CAP -Add and CAER with the
exception of MW-lA; which has been chronically dry and MW-7 which is exempt from testing during the
summer event. Monitoring locations are depicted on the potentiometric map (Sheet 2).
Sampling was performed per the protocols outlined in the WQMP. A summary detailing the construction
of the water monitoring wells is presented on Table 1. The function and integrity of all monitoring locations
were visually evaluated as documented on Table 2. The depth to water in each well was electronically
gaged prior to purging to quantify the static water level elevation. Submersible pumping or bailing was
utilized to purge the wells a minimum of three times the volume of standing water in the well or until dry.
Surface water samples were collected from previously designated locations along discharge features.
During well purging and surface water sample collection the required field parameters were recorded. The
samples were then placed into laboratory -prepared, pre -preserved containers via a new disposable
polyethylene bailer. Samples were collected, kept on ice, and transported to a NC -certified laboratory under
proper chain of custody (C-O-C) protocols and within the specified hold times for each analysis.
Field Parameter Data
Field parameters were recorded including depth to water, pH, specific conductance, temperature, dissolved
oxygen (DO), oxidation reduction potential (ORP) and turbidity. A summary of the field parameter data is
presented in Table 3 and the field sampling data sheet is enclosed in Appendix B.
Laboratory Results
Pace Analytical Services Inc. (PACE) of Huntersville/Asheville, NC performed the laboratory analyses.
All water samples were tested for at least the constituents listed in 40CFR258 Appendix I and 1,4-Dioxane.
Nine wells were tested for mercury as part of assessment monitoring. Corrective action monitoring was
also performed on 13 wells (MW-3, MW-5, MW-6, MW-7, MW-11, MW-12, MW-12D, MW-16, MW-24,
MW-25, MW-26, MW-27 and MW-31) which included a previously approved subset of MNA parameters.
Additionally; supplemental samples MW-1 and MW-lB were analyzed for dissolved methane to assess
remediation progress. Quality control measures implemented during this event included testing of an
equipment blank (EB) and field blank (FB).
2

Water samples were analyzed to the Method Detection Limits (MDL) and reported to the Method Reporting
Limit (MRL) which are both established by the laboratory. Any value above the adjusted MDL and below
the adjusted MRL was flagged as a `j-qualifier" which the laboratory defines as an estimated
concentration. A sampling and analysis table summarizing the locations, laboratory, target analytes and
methods is presented as Table 4. Laboratory results and C-O-Cs are presented in Appendix A.
Quality Control Samples
No constituents were detected in either of the quality control blanks (EB, FB) which may indicate that the
data set is not compromised by field and/or laboratory artifact contamination.
Groundwater Samples Detected Above Standards
Enclosed Table 5 summarizes constituents detected in groundwater and QC samples compared to current
Groundwater Protection Standards (GWP), Interim Maximum Allowable Concentrations (IMAC) and
Groundwater Standards (2L) which have been adopted by the NCDEQ SWS as groundwater compliance
Standards. Although not applicable for regulatory compliance, detections were also compared to Maximum
Contaminant Level (MCL) commonly referenced as the Federal `Drinking Water Standard".
Metals
Four metals were detected in quantifiable concentrations above their respective 2L/IMAC Standard in
samples collected from 12 wells as summarized below.

Surface Water Samples Detected Above Standards
Attached Table 6 summarizes constituents that were detected above MDL compared to the applicable North
Carolina Surface Water Standards (2B) for a Class C waterbody. Surface water detections were also
compared to NC Protective Values and MCL.
Cadmium and copper were detected in elevated concentrations in samples SW-4R and SW-5 respectively.
Groundwater and Surface Water Characterization
At the landfill, groundwater flow direction generally mirrors topography, thus flow direction is from higher
to lower elevations as shown on the potentiometric map included as Sheet 2. Locally, groundwater flow is
expected to be generally westerly toward the Lower Little River, and southerly toward the Catawba River.
Groundwater linear velocity rates calculated using modified Darcy's equation varied greatly and were
slower in the upper bedrock fracture system than the less prominent regolith (Table 7). Streams at
designated monitoring points were visually observed to be of normal seasonal volume, flow rate and low
turbidity. Hydrogeologic parameters appear generally consistent with historical observations.
Corrective Action Update
Groundwater remediation continues to be implemented at the four AOCs designated in the CAP -Add.
General background information and activities performed since the CAER and last semi-annual event are
briefly presented in the following sections.
MNA Analysis (AOCs MW-16, MW-24, MW-26)
Semi-annual MNA monitoring of 14 wells for the full suite of SWS recommended parameters was initiated
on June 30, 2009 and performed during four consecutive semi-annual events to establish a baseline per the
4

CAP -Revision 1. The number of wells requiring MNA analysis was reduced to 10. The parameters and
frequency were also amended per the SWS CAER review response (DIN 14150) dated June 16, 2011. MNA
data collected during this event is presented on Table 5.
Following an acquisition of a 15.7 acre parcel from Crescent Resources on March 3, 2011, extension of the
eastern relative point of compliance downgradient of AOC MW-16 has been approved with conditions by
the SWS on February 18, 2013 (DIN:18502). Recordation of Survey Plat titled Survey for Notice of
Contaminated Site Alexander County Landfill and A Notice and SWS approved Declaration of Perpetual
Land Use Restrictions for this parcel has remained at the Alexander County Register of Deeds Office since
November 13, 2012. Alexander County purchased another 2.15 acre parcel that adjoins the NE corner with
deed recorded on 3/26/18 which effectively increases the relevant compliance boundary in a NE direction.
The SWS approved CAP -Add and CAER (2017) clarifies that groundwater remediation of AOC MW-16
will remain as MNA, rather than other technologies described in the preceding CAP -Add.
Phytoremediation (AOC MW-24)
County personnel planted approximately 200 hybrid poplar trees over an approximate one acre area
between MW-7 and MW-12 in May 2010 in an effort to phytoremediate groundwater in the MW-24 AOC.
The County continued to maintain the fence -enclosed stand during this semi-annual period which included
continuous supplemental watering and eradication of competing vegetation.
Total cumulative VOC concentrations in AOC MW-24 during this event have decreased 64% compared to
its respective 2 year baseline established in 2010 and a statistical increasing trend is not evident.
Assessment of the phytoremediation area which includes tree measurements and downloading groundwater
fluctuation from dedicated transducers will continue semi-annually with the next event scheduled for spring
2019. We recommend that additional trees be planted in the Spring of 2019 to replace trees that have died.
Enhanced Bioremediation via Substrate Injection (AOC MW-26)
In an attempt to remediate benzene as detected in MW-26, Bac-9 was injected 50 ft upgradient in IW-1 on
February 17, 2011 following conditions in the Underground Injection Control (UIC) Permit WI0300160.
The UIC permit was recently renewed and as directed by the UIC post -injection water quality monitoring
of MW-3, MW-11, MW-26, MW-27 and MW-31 is required on a semi-annual basis. Benzene continues to
be detected above the 2L Standard in a sample collected from MW-26. Contaminants remain absent from
MW-31 located along the MW-26 flow path beyond the compliance boundary. Most recent levels of total
VOCs compared to the baseline established during the four events prior to injection exhibited a reduction
both upgradient (-55%) and downgradient (-74%) of the injection point. Most recently, total cumulative
VOCs from all samples in AOC MW-26 decreased 59% and benzene concentrations fell 41% compared to
the baseline averages established during the four events performed over the two years preceding the
injection (Figure 2). Further injections are not planned at this time.
Landfill Gas Extraction (AOCMW-1B)
Three LFG extraction wells (MEW-1, MEW-2, MEW-3) were installed screening the majority of the vadose
zone at the northern border of the closed landfill in the vicinity of the scalehouse. MEW-1 was installed
on August 17, 2010 with MEW-2 and MEW-3 installed on October 20, 2010. Well control heads were
plumbed to a header pipe by the County which was connected to a soil vacuum extraction (SVE) unit on
July 5, 2012. An active LFG blower system pilot study was performed by MESCO between June 14, 2012
and July 12, 2012 to evaluate the effectiveness a vacuum would have on reducing levels of LFG in the soil
which may remediate the low-level VOCs detected in groundwater hydraulically upgradient of the landfill.
A comparison of LFG concentrations and pressures before and after vacuum start-up indicated the system
is capable of eliminating LFG migration at all locations monitored within AOC MW-lB. The active LFG
Collection Control System (LFGCCS) has been in continuous operation since November 1, 2012 and been
verified and documented by MESCO personnel on at least a quarterly basis to be mitigating LFG migration
through the vadose at all locations monitored beyond the extraction wells. Improvement in groundwater
quality has also been observed in response to implementation of the LFG extraction system as summarized
below and shown on Figure 3.

Findings
During this event there were 16 instances of metals detected in quantifiable concentrations above 2L/IMAC
Standards which is typical for this site. Cobalt continues to be the most prevalent metal detected and was
found in 56% of the samples including the background well. The source of metals is believed to be a
product of erosion of natural deposits rather than anthropogenic.
Unprecedented concentrations reported during this event include cadmium, lead and zinc in sample MW-
11 and cobalt in sample MW-15. The reported concentration of cadmium, lead and zinc in sample MW-11
are statistical outliers per Rosner's Outlier Test at a 95% confidence level. None of these metals have
exhibited a statistically significant increase (SSI) via interpretation of intrawell Shewhart CUSUM control
charts with the exception of cadmium at MW-11 (Appendix Q.
Surface water samples SW-4R and SW-5, collected on -site, contained total recoverable forms of metals
including concentrations of cadmium (1.7 uq/L) and copper (6.6 uq/L) respectively. The NC 2B Standard
for these metals is based on the dissolved form and is determined via a calculation that requires a hardness
value which was not quantified. Calculations using a hardness of 400 mg/L were used to convert total
metals to soluble metals, and were found to be at concentrations below the 213 Standard. The source of the
elevated levels of observed metals is not believed to be anthropogenic rather a product of erosion of natural
deposits which were high biased from reaction of acid preservative and sediment entrained in the sample
containers. Since dissolved samples are not permissible by the DWM a direct comparison to 213 Standards
is not possible. We recommend minimizing sediment in sample containers and measuring hardness values
so that a more valid comparison to 213 Standards can be made in the future.
The semi-annual laboratory results indicate that dissolved phase VOCs, consisting primarily of benzene
and a few chlorinated solvents, continue to be detected in groundwater samples collected within 270 feet
of the waste boundary. All VOCs detected during this event remain within their own respective historically
identified range. Total VOC concentrations do not exhibit an increasing trend over time site -wide and in
each of the AOCs. Statistical Sen's Slope trend analysis performed at both a 90% and 95% confidence
interval indicates a downward trend of total VOC concentrations at AOC MW-1B and cumulative of all
wells site -wide since corrective action was initiated. The same statistical analysis indicates no trend at
AOC MW-16, AOC MW-24 or AOC MW-26 Appendix C. Total VOC concentrations during this event,
compared to their own respective averages calculated during the two year baseline period (ended in 2010),
indicate a reduction in each of the AOC's as shown on Figure 4 and summarized below.

Evaluation of current water quality data continues to support assertions drawn in previous reports. VOCs
persist in the upper portion of the aquifer but concentrations continue to decrease over time and distance
away from the landfill. NINA data and previous screening models indicate that the plumes within each
AOC are stabilizing and/or decreasing and there is evidence that natural attenuation is ongoing at the
facility. Implementation of the corrective action measures coupled with natural attenuation is expected to
decrease VOC concentrations in groundwater over time.
Closing
Water quality monitoring and corrective action will continue and the next sampling event is planned for
spring 2019. If you have any questions or comments regarding this report, please contact us at (919) 772-
5393 or by email at [e-mail] or [e-mail].
