Subject: 2023 Annual Compliance Monitoring Report
Former BASF Industrial Landfill
Permit #1102-INDUS-1980
Enka, North Carolina
Dear Ms. Drummond:
ELM Site Solutions (ELMSS), on behalf of BASF Corporation (BASF), herein submits the following
2023 Annual Compliance Monitoring Report for the above -referenced site. Compliance monitoring
activities consisted of groundwater, surface water and landfill gas sampling and analysis in
accordance with the facility's Letter of Closure dated March 13, 2006 (North Carolina Department
of Environment and Natural Resources).
The approved groundwater monitoring network consists of monitoring wells MW-3, MW-4R, MW-
5, and background well MW-6. Wells MW-3 and MW-6 were previously damaged and cannot be
sampled as discussed below. The approved surface water sample locations are SW-1 (upstream)
and DW-2 (downstream) from nearby Hominy Creek located north of the site.
The approved landfill gas monitoring network consists of landfill gas wells LG-1 through LG-10.
Landfill gas well LG-1 was destroyed by road construction activities sometime between March and
June 2019. All groundwater, surface water and landfill gas sample locations are provided on
Figure 1.

Ms. Jaclynne Drummond
2023 Annual Compliance Monitoring Report
September 16, 2024
In a letter dated October 20, 2020, the North Carolina Department of Environmental Quality
(NCDEQ), Solid Waste Section (SWS), approved BASF's request to reduce groundwater sampling
frequency to an annual basis, remove monitoring for volatile organic compounds (VOCs), reduce
the landfill gas monitoring frequency to a semi-annual basis, and eliminate the sampling of a
surface water seep (Seep-1).
Field activities along with groundwater, surface water, and landfill gas monitoring results are
discussed below.
FIELD ACTIVITIES
Field Investigation methods for this monitoring event were conducted in compliance with industry
standards and the U.S. Environmental Protection Agency (EPA) Region IV Field Branch's Quality
System and Technical Procedures. Water levels were measured at each well (i.e., MW-4R and
MW-5) prior to sampling using an electronic water level meter that were converted to groundwater
elevations as provided in Table 1. Groundwater samples were collected from wells MW-4R and
MW-5 on November 9, 2023 using low -flow purge and sample methods. A duplicate sample was
collected from well MW-5 (MW-5 DUP). Purging was accomplished using a variable speed
peristaltic pump and disposable tubing with the pumping rate adjusted to equal the approximate
recharge rate of the well. Indicator parameters of pH, temperature, specific conductivity, turbidity,
dissolved oxygen (DO), and oxidation-reduction potential (ORP) were measured at regular intervals
during purging with a Horiba U-50 water quality meter until the measured values stabilized. Low -
flow purge methods allow the collection of groundwater samples that minimize the total suspended
solid count obtainable without filtering in the field, thus giving a more accurate indication of
dissolved metals present in groundwater. Stabilized water quality parameters for the monitoring
wells are presented in Table 2. Groundwater Sample Collection Records are provided in Appendix
A.
As noted historically, two groundwater monitoring wells (i.e., MW-3 and MW-6) were damaged
sometime between the October 2016 and April 2017 monitoring events and have not been sampled
since October 2016. The total depth of MW-3 was originally 30.2 feet below top of casing (btoc)
and was measured at 41.1 feet btoc during the April 2017 monitoring event. The total depth of
MW-6 was originally 41.2 feet btoc and was measured at 22.2 feet btoc during the April 2017
monitoring event. The damage to these wells were presumably the result of significant grading
operations at the Site, which is now part of an outdoor recreational park under a 2016 NCDEQ
Brownfields Agreement. Neither BASF nor ELMSS were contacted regarding damages to these
wells. Top of casing elevations are currently unknown for these two monitoring wells due to the
damages noted above. Therefore, a potentiometric contour map could not be generated for this
groundwater monitoring event. The location and relative groundwater elevations for wells MW-4R
and MW-5 as measured on November 9, 2023, are also provided on Figure 1.
Surface water samples SW-1 (upstream) and DW-2 (downstream) were collected directly from
Hominy Creek by filling pre -preserved laboratory sample containers using a peristaltic pump and
VA

disposable tubing. Stabilized water quality parameters for the surface water samples are presented
in Table 2. Surface Water Sample Collection Records are provided in Appendix A.
Nine landfill gas monitoring wells (IG-2 through LG-10) were monitored on November 8, 2023. LG-
1 was destroyed by road construction activities sometime between March and June 2019 as noted
above. Measurements of percent methane (% CH4) by volume, percent oxygen (% 02), percent
carbon dioxide (% CO2), and hydrogen sulfide (H2S) in parts per million (PPM) were recorded at
the landfill gas monitoring wells using a calibrated MRU Optima 7 instrument. Percent lower
explosive limit (% LEL) was calculated by multiplying % CH4 by 20. The Landfill Gas Monitoring
Data Form for the monitoring events are provided in Appendix B.
ANALYTICAL RESULTS
Pace Analytical Services, Inc. (a North Carolina certified laboratory) analyzed the groundwater and
surface water samples for Appendix I metals by EPA Methods 6010, mercury by EPA Method 7470,
sulfate by EPA Method 300.0, and total dissolved solids (TDS) by SM 2540C. A copy of the
analytical report is provided in Appendix C. As required by the SWS, a laboratory electronic data
deliverable (EDD) will be provided to the department for this report.
For data analysis, groundwater analytical results were compared to the 15A NCAC 2L Groundwater
Quality Standards (i.e., 2L Standards), the regulatory basis established to determine groundwater
quality. The sample collected from well MW-5 contained cobalt at a concentration of 14.5
micrograms per liter (ug/L) exceeding its 2L Standard of 1 ug/L. No other 2L Standard exceedances
were identified in MW-4R or MW-5. Analytical results are summarized in Table 3.
Surface water results were compared to 15A NCAC 2B Surface Water Standards for Class C
waters (i.e., 2B Standards). No 2B Standard exceedances were identified during the surface water
sampling event. Analytical results are summarized in Table 3.
The monitored landfill gas wells exhibited 0% methane by volume for the monitoring event in all
wells with the exception of LG-6 (0.01, or 0.2% LEL) and LG-8 (0.04, or 0.8% LEL). The action
limit for methane is >_5% by volume, or 100% LEL. Thus, no landfill gas samples exceeded the
action limit. Landfill gas monitoring data for this monitoring event are summarized on Table 4.
Historical landfill gas data is provided on Table 5.
SUMMARY
The following summarizes results and observations during this reporting period:
• Groundwater samples were not collected from wells MW-3 and MW-6 due to previous
damage to the wells.

Ms. Jaclynne Drummond

• Cobalt was detected in the sample from well MW-5 at a concentration of 14.5 ug/L,
exceeding its 2L Standard of 1 ug/L. It should be noted that background soil samples were
collected during an initial seep investigation (adjacent to MW-5) in 2010 to assess naturally
occurring site conditions. Results from the study included detection of cobalt at a maximum
concentration of 9.34 milligrams per kilogram (mg/kg). The NCDEQ - Inactive Hazardous
Sites Branch (IHSB) has established a soil cleanup level protective of groundwater for
cobalt at 0.9 mg/kg (July 2024). Some, if not all, of the cobalt detected during groundwater
monitoring may be due to mobilization of background metals in soil.
• Landfill gas monitoring was not performed at LG-1 due to well destruction by road
construction activities between March and June 2019.
• The landfill gas wells exhibited 0% LEL during the monitoring events with the exception of
LG-6 (0.2% LEL) and LG-8 (0.8% LEL). All landfill gas wells are below the action level of
100% LEL.

QUALIFIERS
Project: BASF Enka
Pace Project No.: 92698068
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.
