Semi-Annual Monitoring Report-October 2024
Iredell County Closed Unlined C&D Landfill Page 1
Introduction
On behalf of Iredell County, Municipal Engineering, Inc. (MESCO) is pleased to present this Semi-
Annual Water Quality Report for an event performed at the Iredell County Closed Unlined
Construction and Demolition (C&D) Landfill on October 2-4, 2024. North Carolina Department of
Environmental Quality (NCDEQ) Solid Waste Section (SWS) Rules at Title 15A, North Carolina
Administrative Code, Subchapter 13B, Rule .0601 requires that Iredell County provide a report to the
SWS that documents water quality at the facility on a semi-annual basis.
During this event, 1,4-dioxane was detected above applicable North Carolina Groundwater Quality
Standards (2L Standards) in samples collected from one (1) monitoring well which is believed to be
evidence of a landfill release. Zinc was detected above Surface Water Quality Standards (2B Standards)
in a surface water sample collected upstream of the landfill facility, that is believed to be from a release
from an off-site source.
Background
The Iredell County Closed C&D Landfill, permit #49-03, is located at 354 Twin Oaks Road, Statesville,
North Carolina. The closed, unlined C&D landfill consists of three contiguous phases (Phases 1, 2 & 3)
which are treated as a single unit in this report. The site location topographic map is depicted in the
attached Figure 1.
Water quality at this portion of the facility has been continuously monitored at least on a semi-annual
frequency since 1993. The unlined C&D landfill (CDLF) ceased accepting waste on June 27, 2008 and
received a closure certification on November 30, 2011. Current water quality data was compared to all
historical data compiled from this site since 1993.
An Alternative Source Demonstration Addendum (ASD-Add), which established Site Maximum
Allowable Contaminant (SMAC) regulatory compliance levels for five metals (cadmium, chromium,
cobalt, thallium and vanadium), was approved by the NCDEQ SWS on January 30, 2020 (FID:1388745).
The SSW approved a request to reduce the number of locations that Iredell County must target 1,4-
dioxane on January 13, 2020 (FID:1387339) and did not require testing surface water points SW-3 or
SW-6 per an email dated August 29, 2023.

This report contains sampling procedures, field and laboratory results, groundwater and surface water
characterization information submitted in general accordance with 15A NCAC 13B.1632(i), the SWS
Environmental Monitoring Report Form and SWS issued memorandums. Also included in this report are
tables and figures concerning constituent detections, groundwater flow rate and direction, field
parameters, a potentiometric map, statistical analyses, and the laboratory analytical reports with quality
assurance/quality control data and chains-of-custody (COC) documents. During this event samples were
not collected and analyzed for Per- and Polyfluoroalkyl Substances (PFAS) since the County has already
met the requirement to sample PFAS for two (2) events, in accordance with the SWS memorandum dated
March 13, 2023, and as amended July 17, 2023.

Sampling Procedure
MESCO performed the sampling activities in general accordance with the NC Solid Waste Section
Guidelines for Groundwater, Soil, and Surface Water Sampling revised April 2008 and the current site-
specific Sampling and Analysis Plan (SAP) dated October 10, 2006. Water samples were collected from
ten (10) downgradient monitoring wells (MW-9R, MW-9RR, MW-10R, MW-16, MW-22, MW-23, MW-
24S, MW-24D, MW-26S, MW-26D) and three surface water points (SW-2, SW-3, SW-6). Samples were
also collected from MW-32 and MW-37, which serve as the designated background wells for the CDLF
and lined Phases 1, 2, 5 & 6, and from a stream location referred to as “SW-of-the-Confluence” to
document zinc occurrences that appear to be originating from an upstream, off-site source. Quality control
measures implemented during this event included analysis of an equipment blank (EB). Monitoring
locations are shown on Figure 2.
A summary detailing the construction of the groundwater monitoring wells is presented in Table 1. The
function and integrity of all monitoring locations were visually evaluated 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. Submersible pumping methodology or bailing was utilized to purge the wells to a minimum of
three times the volume of standing water in the well or until dry. Samples were collected up to 24 hours
following purging. Surface water samples were collected from previously designated locations. 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 C-O-C protocols within the specified hold times for each analysis.
Field Parameter Data
Stabilized field parameters were recorded during purging which included depth to water, pH, specific
conductivity, temperature, hardness (for surface water samples only). A summary of the field parameter
data is presented in Table 3. Field parameter data is found on Appendix A.
Laboratory Results
Pace Analytical Laboratories (PACE) (NC Cert. # 12, 40, 667) performed the lab analysis. Groundwater
and surface water samples were generally analyzed for the constituents listed in 40CFR 258 Appendix I,
tetrahydrofuran, and 1,4-dioxane. Surface water points were tested for total recoverable metals. A
summary of the locations, targeted parameters and analytical methods are shown on Table 4. Laboratory
results and C-O-Cs are contained in Appendix B.
Water samples were analyzed to the laboratory-established Method Detection Limits (MDL) and any
value between the MDL and laboratory-established Reporting Limit (RL) is qualified by the laboratory
with a “J” as an estimated concentration. Estimated concentrations are considered non-quantifiable and
discretion should be used prior to making decisions based solely on a value that the laboratory flags as an
estimate.

Table 5 summarizes constituents detected in groundwater and QC samples compared to the 2L Standards,
Interim Maximum Allowable Contaminant (IMACs) and Site Specific Maximum Allowable Contaminant
Levels (SMAC), which have been recognized by the SWS as groundwater compliance Standards. The
groundwater 2L Standards presented are current as of April 1, 2022. 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”. Table 6 lists the constituents
detected in surface water samples compared with the NC Division of Water Resources “Surface Water
Quality Standards, Criteria & Protected Values”, or 2B Standards, modified July 26, 2021.
Quality Control Samples
No constituents were detected in the EB.
Groundwater Samples Above Standards
Metals
No metals were detected above the applicable compliance standards during this event.
VOCs
The constituent 1,4-dioxane was detected in downgradient monitor well MW-9RR at a concentration of
8.1 ug/L, above the 2L Standard of 3 ug/L. No other samples collected from the monitoring well network
reported the presence of VOCs above the applicable 2L Standard.
Surface Water Samples Above Standards
An unnamed tributary of Fourth Creek (Class C), which serves as the local discharge feature south and
east of the closed C&D landfill, was monitored at four locations. Consistent with previous events a
supplemental sample (SW-S of Confluence) collected at the confluence of a separate drainage which
originates off-site, contained total a zinc concentration of 588 ug/L, which is above its calculated
dissolved phase 2B Standard [274.93 (acute), 277.18 (chronic) ug/L] when corrected for hardness. No
other surface water sample contained total zinc or any other metal above the applicable 2B Standard.
Groundwater and Surface Water Characterization
A potentiometric map for the surficial aquifer created from groundwater elevation data collected during
this event is included as Figure 2. Groundwater flow directions and rates were calculated using modified
Darcy's equation and presented as Table 7. Groundwater flow at the C&D landfill is to the east toward
the unnamed tributary to Fourth Creek. Inferred flow directions and gradients are generally consistent
with those historically reported. Streams located within the facility boundaries were visually observed to
have moderate seasonal volume, moderate flow and low turbidity.

Findings
During this event 1,4-dioxane was observed in groundwater samples collected from one well above the
2L Standard which is evidence of a landfill release. The lone surface water standard violation is not
attributed to a landfill release as it originates upstream of the property line.
Closing
Post-closure, semi-annual water quality monitoring is planned to continue in the Spring 2025.

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 EPAMethod 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.

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 EPAMethod 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.

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 EPAMethod 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.
TNI - The NELAC Institute.
