Introduction
On behalf of Alexander County, Municipal Engineering, Inc. (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 June 27-29, 2023. North Carolina Department of Environmental Quality
(NCDEQ) Solid Waste Rules at Title 15A North Carolina Administrative Code Subchapter 13B (15A
NCAC 13B) Rule.1632(i) 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
23 wells contained between one and three constituents above regulatory compliance Standards. Metal
detections are generally believed to originate from naturally occurring deposits. The source of VOCs is
likely anthropogenic. Cobalt was detected at concentrations that may be above surface water compliance
values in two downstream surface water samples. 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. The CAER originally due in 2022 has been
postponed, with SWS approval pending the outcome of a property acquisition needed to restore the
northern compliance boundary to a previous location, in order to avoid unnecessary mitigation.
Background
The active Alexander County C&DLF 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 County relinquished a 165-acre tract located north of the landfill to Carolina
Land and Lakes on December 31, 2021. Through conveyance of this property the landfill compliance
boundary was significantly reduced and 10 groundwater monitoring wells and a surface water monitoring
points are now located off -site. The County has notified the SWS of the issue, and the County plans to
reacquire at least a 300-foot buffer such that the wells will be located within Alexander County property
lines. A draft map representing a conceptual reacquisition of approximately 13 acres of land to restore the
original compliance boundary has been reviewed and tentatively approved by the SWS. Pending approval
by the County Board of Commissioners and CLL, the final map depicting the land acquired by the
County and reestablished compliance boundary will be recorded with the Register of Deeds and submitted
to the SWS. The site location topographic map, which reflects boundaries prior to the property
relinquishment, is depicted as 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
I

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-1B, 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).
This report contains a description of sampling procedures, field and laboratory results, a corrective action
update, ground/surface water characterization, and findings as specified within 15A NCAC 13B.1632(i),
the SWS Environmental Monitoring Report Form and SWS memorandums. Tables concerning well
construction, field observations, field parameter data, a sampling and analysis summary, parameter
detections compared to applicable Standards, and groundwater flow directions/rates are included along
with a potentiometric map, time -series graph, quality assurance/quality control data, and laboratory
analytical data results.
Sampling Procedures
MESCO personnel performed this sampling event generally 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.
Samples were collected from MW-IA which is atypical since it typically has insufficient recharge. MW-
3 and MW-7 were not sampled during this event since they are only tested annually in the winter.
Monitoring locations are depicted on the potentiometric surface map (Sheet 2).
Sampling was performed per the protocols outlined in the WQMP. A summary detailing the construction
of the water quality monitoring wells is presented in Table 1. The function and integrity of all monitoring
locations were visually evaluated and maintenance performed as documented in Table 2. The depth to
water in each well was electronically gaged prior to purging to quantify the static water level elevation.
2

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
stabilized 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 (surface water only) 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 constituents
and MNA performance parameters as prescribed in the approved WQMP. 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 the quality control equipment blank (EB) or field blank (FB).
Groundwater Samples Detected Above Standards
Table 5 summarizes constituents detected in groundwater and QC samples compared to North Carolina
Groundwater Quality Standards (2L Standard). 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 or two total recoverable forms of metals were detected above their respective 2L Standard in samples
collected from 26 wells, including the background well, as summarized below.

Concentrations in ug/L
VOCs
Benzene was detected above the RL and 2L Standard (1.0 ug/L) in samples collected from NM-5 (2.8),
MW-9 (1.2), MW-11 (3.5), MW-12 (2.5), MW-15 (2.1) and MW-26 (1.7). 1,4-dichlorobenzene was
found in sample MW-11 (8.9) which is above the 2L Standard (6 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 concentrations
of contaminates exceeding the 2L/2B Standards during this event is shown in Sheet 2.
Surface Water Samples Detected Above Standards
Table 6 summarizes constituents that were detected above the MDL compared to compliance values
listed in the current version of the NC Division of Water Resources Surface Water Quality Standards (213
Standard), Criteria & In -Stream Target Values (ISTV) tables dated July 26, 2021.

Total cobalt was detected in grab samples from SW-3 (4.2 ug/L) and SW-5 (21.4 ug/L) which is above
the dissolved NC ISTV for chronic (1.6 ug/L) and acute (16 ug/L) impacts. However, because single grab
samples of the total form of cobalt are reported rather than multiple samples of the dissolved form, a
direct comparison to the cobalt NC ISTV for compliance purposes is inappropriate.
Groundwater and Surface Water Characterization
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 west toward the Lower Little River and south toward the Catawba River which
North Carolina classifies as a WS-IV; CA (Water Supply Class IV; Critical Area). 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 moderate 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. A
required corrective action costs restatement was submitted to the SWS on December 14, 2022 and was
approved by the SWS on January 10, 2023. 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 in accordance with the CAP -Revision 1. The number of wells requiring MNA analysis was
reduced to 10 wells. The parameters and frequency were also amended in accordance with the SWS
CAER review response (DIN 14150) dated June 16, 2011. A large number of MNA parameters were
targeted in 13 wells during this event and detections are 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 had 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 March 26, 2018, 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.
5

Phytoremediation (AOC MW-24)
County personnel planted approximately 200 hybrid poplar and willow 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 planted 25 additional hybrid willow trees in the spring of 2022 to replace
trees that have died, but they appear to have also died. 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 38% compared
to its respective 2-year baseline established in 2010, and a statistically decreasing trend is evident.
Assessment of the phytoremediation area, which includes tree measurements and the downloading of
groundwater fluctuation data from dedicated transducers was performed by MESCO. The majority of the
trees appear to be dying or have died. MESCO recommends that additional trees be planted this Spring to
compensate for the observed mortality.
Enhanced Bioremediation via Substrate Injection (AOC MW-26)
In an attempt to remediate benzene 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 renewed and as directed by the UIC permit, post -injection water quality monitoring
of MW-3, MW-11, MW-26, MW-27 and MW-31 is required on a semi-annual basis. Most recent
concentrations of total VOCs and benzene downgradient of the injection point decreased 57% and 21%
respectively, compared to the baseline established during the four events prior to injection (Figure 2).
The UIC Permit was renewed again on March 10, 2023, however, additional injections are not planned at
this time.
Landfill Gas Extraction (AOC MW-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 scale house. 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. Improvements in groundwater quality have been observed in response to implementation of the
LFG extraction system as demonstrated by a reduction of benzene (93-96%), total VOCs (98-100%) and
dissolved methane (99%) as shown on Figure 3.
2

The LFGCCS is planned to remain in operation and will continue to be monitored and assessed on a
quarterly basis.
Findings
During this event there were 23 instances of metals detected in concentrations above 2L Standards which
is typical for this site. Cobalt continues to be the most prevalent metal detected and was found in every
sample including the background well. All metal concentrations were found within their historically
identified range (Appendix Q. The source of metals may be attributed to the presence of natural
deposits however, it is unknown if the observed metals have leached in response to changes in redox
conditions, anoxic environments, pH, oxidation state of metals and microbial activities.
The laboratory results indicate that dissolved phase VOCs, consisting primarily of benzene and a few
low-level 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. Statistical Mann Kendall trend analysis performed at both a 90% and 95%
confidence interval indicate a stable or downward trend of total cumulative VOC concentrations at every
well except for MW-5. Total VOC concentrations during this event, compared to their own respective
averages calculated during the two-year baseline period (ended in 2010), exhibited a reduction in each of
the AOC's as shown on Figure 4. Statistical analysis calculations are found in Appendix C 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. MNA data and previous screening models indicate that the plumes within each
7

AOC are stable 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 result in
the continued decrease of VOC concentrations in groundwater over time.
It is recommended that surface water samples be tested for dissolved metals if the total form is found
elevated, and compared to dissolved surface water 2B Standards to better determine if surface waters are
impaired.
Closing
Water quality monitoring and corrective action is planned to continue in December 2023. A CAER was
planned to be drafted this spring. However, the CAER is postponed until the compliance boundary is rei-
stablished north of the landfill, which the County is working towards. Drafting a CAER beforehand
would require a discussion of implementing additional corrective actions to conform with Rules which
would ultimately not be necessary. The County has received tentative approval from the SWS for the
reacquisition of approximately 13 acres of land to the north of the landfill, formerly owned by the County,
in order to reestablish its northern compliance boundary as near to its previous location as possible. At the
time of this report the County is negotiating the acquisition terms with the current property owner,
Carolina Land & Lakes. The County will notify the SWS once the property is reacquired.

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 2L STD recognized by NC SWS as regulatory groundwater Standard
Highlighted Above Established MCL Drinking Water Std. (No regulatory significance)
BG = Background Well Sample, S = Sentinel Well Sample, QC = Quality Control Sample
MDL = Adusted 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 "" qualifier designation.
RL = Reporting Limit defined by Pace laboratory as "The lowest concentration value that meets proect requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix."
2L = NC 21- Groundater Standard 15A NCAC 02L .0202
MCL = Maximum Contaminant Level for drinking water established by the USEPA.
J = " J-qualified". Defined by the lab as "estimated concentration above the adusted method detection limit and below the adusted 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
Pace Project No.: 92675144
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.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
B Analyte was detected in the associated method blank.
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
H3 Sample was received or analysis requested beyond the recognized method holding time.
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.
R2 RPD value was outside control limits due to matrix interference
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.
