Subject: September 2020 Semi -Annual Sampling Report
Cabarrus County Unit 1 Landfill
Facility Permit No. 1302-MSWLF-1974
Dear Ms. Drummond:
CDM Smith Inc., on behalf of Cabarrus County, is submitting an electronic copy of the September 2020
semi-annual sampling report for the recent event completed at the Cabarrus County Unit 1 Landfill.
This letter report constitutes the second semi-annual sampling event for 2020. The approved
monitoring well network consists of compliance wells MW-5, -7, -8A, -10, -11, and background wells
CD-1s and -1d. The monitoring network also includes surface water sample locations SW-1 and -2.
Field activities and sampling results for the groundwater and surface water samples are discussed
below.
Field Activities
Groundwater and surface water samples from the Cabarrus County Unit 1 Landfill were collected on
September 22-25, 2020. Groundwater samples were collected from the monitoring wells by use of
disposable, laboratory decontaminated bailers. Monitoring well and surface water sample locations
for the Unit 1 landfill are provided on Figure 1.
Groundwater elevations were measured at each well prior to sampling and are presented in Table 1.
Well construction details for each monitoring well are also provided in Table 1. These groundwater
elevations were used to construct potentiometric contours for this sampling event and are presented
on Figure 1. After depth to groundwater was measured, each well was purged prior to sampling to
provide fresh formation water within the well water column. Each purge volume was measured for
pH, conductivity, turbidity, temperature, dissolved oxygen, and oxidation-reduction potential using a
YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter. The water
quality parameters at the time of sampling are presented in Table 2.

Sampling Results
Pace Analytical Services, LLC, located in West Columbia, South Carolina, analyzed the groundwater
samples for North Carolina Appendix I volatile organic compounds (VOCs) and metals. In a letter dated
May 28, 2019, the Solid Waste Section (SWS) requested that all groundwater and surface water
samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On July 1, 2019, the
SWS approved the removal of 1,4-dioxane from the sampling program for CD-1s and -1d due to two
consecutive non -detect events (January and May 2019). Samples were collected from MW-5, -7, -8A,
-10, -11, and SW-1 and -2 during the September 2020 sampling event and analyzed for 1,4-dioxane
due to previous detections of 1,4-dioxane. Sample results are provided below.
The analytical results were reported to the laboratory specific method detection limit (MDL) and are
quantifiable at or below the method reporting limit (MRL). All monitoring wells for the Unit 1 Landfill
had detections of analytes above the MDL but below the MRL. These detections were qualified as
estimated or "J" flags.
The following list indicates the VOCs and metals detected above the MRL at each sampling location.
No "J" flag detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L)
Groundwater Standard, Interim Maximum Allowable Concentration (IMAC), or 15A NCAC 02B .0211 or
North Carolina In -Stream Target Value Surface Water Quality Standards for Class C Waters. A
complete summary of all detected and estimated concentrations from the May 2011 through the
September 2020 sampling events is presented in Table 3. Laboratory data reports are provided in
Appendix A.

"J" flags were not included in the previous list, but several locations had "J" flag detections that
exceeded the standards. These constituents along with their location are listed below.
Cobalt: MW-S, SW-1, and -2
Vanadium: CD-1s, MW-7, and -8A
Trip and equipment blanks and a duplicate sample were analyzed for quality control. The trip blank
had no detections above the MDLs. The equipment blank had an estimated detection of acetone
below its NC 2L Groundwater Standard. The duplicate sample, identified as DUP-1, was collected from
MW-10, and had similar analyte concentrations as those detected in MW-10.
Metals detected above the standards are likely naturally occurring based on concentrations in the
background monitoring wells or are from elevated turbidity at the time of sample collection. VOCs
detected above the standards in several of the compliance wells will continue to be monitored. Table
4 presents a summary of all analytes detected during the September 2020 sampling event that
exceeded the NC 2L Groundwater Standards or IMACs. The next semi-annual sampling event will be
completed in the spring of 2021.

Notes:
1. All units are in micrograms per liter (parts per billion).
2. "- Interim Maximum Allowable Concentration (IMAC)
3. dup - Duplicate Sample
4. J - Indicates the analytical result is an established concentration between the method detection limit and the adjusted reporting limit.
5. B, B-01-The analyte concentration detected in the method blank was greaterthan the method detection limit.
6. CN - Detected silver concentrations were determined to be the result of contamination from the preservative acid.
Concentration exceeds the 15A NCAC 02L .0202 (North Carolina 2L) or IMAC Standard
- Indicates the result is below the detection limit.

3. 131- A Standard for total chromium has not been established. The value provided is for chromium (III).
4. NS - No Standard
5.' - North Carolina In -Stream Target Value
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. CN - Detected silver concentrations were determined to be the result of contamination from the preservative acid.
Concentration exceeds the North Carolina 2B or In -Stream Target Value Freshwater Aquatic Life Standard for Class C Waters - June 2019
