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) between December 28-31, 2020. 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 19 wells
contained between one and three constituents above regulatory compliance Standards. Metal detections
are generally believed to originate from erosion of natural deposits. The source of VOCs is likely
anthropogenic. VOC concentrations continue to decrease over time and distance. No constituents were
detected in surface water samples above values listed in the NC 2B surface water Standards table.
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 implementation of the contingency plan is not required.
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 I (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-lB, 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).
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. 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,
oxidation reduction potential (ORP), dissolved oxygen (DO), hardness and turbidity. A summary of the
field parameter data is presented in Table 3 and the field sampling data sheet is enclosed in Appendix A.
Laboratory Results
Pace Analytical Services Inc. (PACE) of Huntersville/Asheville, NC performed the laboratory analyses.
Groundwater, surface water and quality control samples were tested for a mix of Appendix I parameters,
mercury and MNA performance constituents as prescribed in the approved water quality monitoring plan.
Water samples were analyzed to the Method Detection Limits (MDL) and reported to the Reporting Limit
(RL) which are both established by the laboratory. Any value above the adjusted MDL and below the RL
was flagged as a "j-qualifier" which the laboratory defines as an estimated concentration. Estimated
concentrations are considered non -quantifiable and discretion should be made prior to making decisions
based solely on an approximate value. 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 B.

Quality Control Samples
No constituents were detected in either of the quality control equipment and field blanks (EB, FB).
Groundwater Samples Detected Above Standards
Table 5 summarizes constituents detected in groundwater and QC samples compared to groundwater
compliance standards which include Interim Maximum Allowable Concentrations (IMAC) and North
Carolina Groundwater Standards (2L). Although not applicable for regulatory compliance purposes the
detections are also compared to the Maximum Contaminant Level (MCL) commonly referenced as the
Federal "Drinking Water Standard".
Metals
One to three total recoverable forms of metals were detected above their respective RL and NC 2L
Standard/IMAC Value in samples collected from 17 wells as summarized below.

VOCs
Benzene was detected above the RL and 2L Standard (1.0 ug/L) in samples collected from MW-3 (4.9),
MW-5 (2.6), MW-7 (2), MW-11 (2.7), MW-12 (2.6), MW-15 (2.1) and MW-26 (1.5). 1,4-
dichlorobenzene was found in sample MW-3 at 8 ug/L which is above the NC 2L Standard (6 ug/L).
Vinyl chloride was detected in sample MW-7 at 2.3 ug/L which exceeds its NC 2L Standard (0.03 ug/L).
A bar graph and table comparing the most recent levels of VOCs exceeding the 2L Standard compared to
their respective maximum observed levels is presented on Figure 1. A site map depicting the spatial
distribution of VOC concentrations exceeding the 2L Standard during this sampling event is shown in
Sheet 2.
Surface Water Samples Detected Above Standards
Attached Table 6 summarizes constituents that were detected above the MDL compared to compliance
values listed in the current version of the Division of Water Quality Surface Water Quality Tables.
Cobalt was detected in sample SW-5 at 14.4 ug/L which is above the NC ISTV (4 ug/L).
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 (ADCs 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 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
4

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 supplemental watering and eradication of competing vegetation.
Total cumulative VOC concentrations in AOC MW-24 during this event have decreased 46% compared
to its respective 2 year baseline established in 2010 and a statistical decreasing trend is evident.
Assessment of the phytoremediation area which includes tree measurements and downloading
groundwater fluctuation from dedicated transducers was performed by MESCO. The majority of the
trees appear to be dying or have died; therefore, Alexander County should consider replanting trees.
Enhanced Bioremediation via Substrate Injection (AOC MW-26)
hi 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 has risen
above 2L Standards in MW-26 during this event. Contaminants remain within allowable levels at 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 (-5%) and downgradient (40%) of the injection point. Most recently, total cumulative
VOCs from all samples in AOC MW-26 decreased 13% and benzene concentrations fell 30% compared
to the baseline averages established during the four events performed over the two years preceding the
injection (Figure 2). Additional injections are not planned at this time.
Landfill Gas Extraction (AOC MW-M)
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-113. 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.

Notes:
Units ug/L unless shown otherwise, Blank cells means not detected above MDL, -- means parameter not analyzed, NE means not established.
Bold Above RL and Established 21JIMAC/ recognized by NC SWS as regulatory groundwater Standard
Highlighted Above Established MCL Drinking Water Std. (No regulatory significance)
BG = Background Well Sample, S = Seminal Well Sample
MDL = Adjusted Method Detection Limit established by the laboratory via a statistical calculation.
Since the MDL is below the point of calibration, results reported down to the MDL are not reliable and must be qualified as estimated values and, as such, carry a "J" qualifier designation.
RL = Reporting Limit defined by Pace laboratory as 'The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix."
2L = NC 2L Groundater Standard 15A NCAC 02L .0202
IMAC = Interim Maximum Allowable Concentration
MCL = Maximum Contaminant Level for drinking water established by the USEPA.
J = "J-qualified". Defined by the lab as "estimated concentration above the adjusted method detection limit and below the adjusted reporting limit".
(N) Preliminary source is believed to be Natural originating from erosion of natural deposits. Source not anthropogenic.
(L) Prelilminary source is believed to be anthropogenic with Landfill Gas Wor leachate as suspected transport mechanism.
A definitive source of the detections was not determined as part of this report.

QUALIFIERS
Project: ALEXANDER LF-SWS
Pace Project No.: 92514193
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI -The NELAC Institute.
ANALYTE QUALIFIERS
C8 Result may be biased high due to carryover from previously analyzed sample.
D3 Sample was diluted due to the presence of high levels of non -target analytes or other matrix interference.
H3 Sample was received or analysis requested beyond the recognized method holding time.
IH This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.
IK The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.
R1 RPD value was outside control limits.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.
v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.
v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the
associated samples may have low bias.
