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 an electronic
copy of the 2022 Annual Compliance Monitoring Report for the above -referenced site. This letter
report presents results of sampling activities conducted on April 13, 2022, which constitutes the
annual groundwater and surface water monitoring event for 2022. The approved groundwater
monitoring network consists of monitoring wells MW-3, MW-4R, MW-5, and background well MW-
6. The monitoring network also includes surface water sample locations SWA (upstream) and
DW-2 (downstream) from nearby Hominy Creek located north of the site. 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
(occurring in April), remove monitoring of volatile organic compounds (VOCs), reduce the landfill
gas monitoring frequency to a semi-annual basis (occurring in April and October) and eliminate the
sampling of a surface water seep (Seep-1).
In addition to groundwater and surface water monitoring, landfill gas monitoring was conducted on
October 27, 2021 and April 13, 2022 during this reporting period. A total of 10 landfill gas monitoring
wells (LG-1 through LG-10) were installed in 2010.

Ms. Jaclynne Drummond
2022 Annual Monitoring Report
August 13, 2022
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. Groundwater samples were collected from wells MW-4R and
MW-5 on April 13, 2022 using low -flow purge methods. A duplicate sample was collected from well
MW-5 (MW-5 DUP). Purging was accomplished by 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 regularly during purging with a YSI
Pro Plus 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 constituents present
in the groundwater. Groundwater and surface water sample collection record sheets are provided
in Appendix A. Water levels were measured at each well prior to sampling using an electronic
water level meter and were converted to groundwater elevations (Table 1).
As noted historically, two groundwater monitoring wells (MW-3 and MW-6) were altered between
the October 2016 and April 2017 monitoring events and have therefore 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 October 2016 monitoring event. The total depth of MW-6
was originally 41.2 feet btoc and was measured at 22.2 feet btoc during the October 2016
monitoring event. The alterations to these wells were presumably conducted during 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 modifications to
these wells. Top of casing elevations are currently unknown for these monitoring wells due to the
alterations 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 April 13, 2022 are 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
disposable tubing. Surface water sample locations are shown on Figure 1. Stabilized water quality
parameters for the monitoring wells and surface water sample locations are presented in Table 2.
A total of nine landfill gas monitoring wells (LG-2 through LG-10) were monitored on October 27,
2021 and April 13, 2022. LG-1 was destroyed at an unknown time by road construction activities
performed between March 2019 and June 2019. Neither BASF nor ELMSS were contacted
regarding this incident. Landfill gas well locations are presented on Figure 1. Measurements of
percent methane (% CHa) by volume, percent oxygen (% 02), percent carbon dioxide (% CO2), and
l%

hydrogen sulfide (H2S) in parts per million were recorded at the landfill gas monitoring wells using
a calibrated Landtec GEM 5000+ instrument. Percent lower explosive limit (% LEL) was calculated
by multiplying % CH4 by 20. Landfill gas well LG-10 was missing an airtight fitting on the wellhead.
The Landfill Gas Monitoring Data Forms for the monitoring events are provided in Appendix B.
ANALYTICAL RESULTS
Eurofins TestAmerica in Pittsburgh, Pennsylvania (a North Carolina certified laboratory) analyzed
the groundwater and surface water samples for Appendix I metals by EPA Methods 602013,
mercury by EPA Method 7470A, sulfate by EPA Method 9056A, and total dissolved solids (TDS)
by SM 2540C. Due to the alterations to groundwater monitoring wells MW-3 and MW-6 discussed
above, no samples were collected from these wells. Surface water samples were collected from
Hominy Creek at upstream location SW-1 and downstream location DW-2. A copy of the analytical
report is presented in Appendix C. As required by the SWS, a laboratory EDD is attached to this
letter report.
For data analysis, groundwater analytical results were compared to the 15A NCAC 2L Groundwater
Standards (21- Standards), the regulatory basis established to determine groundwater quality. The
sample collected from well MW-5 and duplicate sample MW-5 DUP contained cobalt (17.1 and
17.2 micrograms per liter (ug/L), respectively) and vanadium (1.20 and 1.50 ug/L, respectively) at
concentrations exceeding their respective 2L Standards of 1 and 0.3 ug/L. The sample collected
from well MW-4R contained sulfate (415,000 ug/L) at a concentration above its 2L Standard of
250,000 ug/L. No other 2L Standard exceedances were identified during the April 2022
groundwater monitoring event. Analytical results are summarized in Table 3.
Surface water results were compared to 15A NCAC 2B Surface Water Standards for Class C
waters (213 Standards). Mercury was detected in both surface water samples (SW-1 and DW-2) at
similar concentrations (0.210 and 0.212 ug/L, respectively) above the 2B Standard of 0.012 ug/L.
No other 2B Standard exceedances were identified during the April 2022 surface water sampling
event. Analytical results are summarized in Table 3.
As noted above, landfill gas monitoring was conducted on October 27, 2021 and April 13, 2022 for
the nine landfill gas wells located near the waste boundary. The monitored gas wells exhibited 0%
methane by volume for the monitoring events with the exception of LG-5 and LG-6 (April 2022
sampling event), both indicating 0.1 % methane, or 2% LEL. The action limit for methane is >_5%
CH4 by volume, or 100% LEL. Landfill gas monitoring data are summarized on Table 4A and Table
4B. Historical landfill gas data is provided on Table 5.
SUMMARY
The following summarizes results and observations obtained during this reporting period:
3

Ms. Jaclynne Drummond
2022 Annual Monitoring Report
August 13, 2022
• Groundwater samples were not collected from MW-3 and MW-6 due to unknown and
unauthorized well construction modifications.
• Cobalt was detected in the sample from well MW-5 and in duplicate sample MW-5 DUP at
concentrations of 17.1 and 17.2 ug/L, respectively, 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
(January 2022). In addition, significant road construction activities (i.e., earthwork with
dozers and excavators) were occurring in the vicinity of MW-5 during the April 2022
sampling event. Some, if not all, of the cobalt detected during monitoring may be due to
mobilization of background metals from soil.
• Vanadium was also detected in the sample from well MW-5 and in duplicate sample MW-5
DUP at concentrations of 1.20 and 1.50 ug/L, respectively, exceeding its 2L Standard of 0.3
ug/L.
• Sulfate was detected in the sample from well MW-4R at a concentration of 415,000 ug/L
exceeding its 2L Standard of 250,000 ug/L.
• Mercury was detected in both surface water samples SW-1 (upstream) and DW-2
(downstream) at respective concentrations of 0.210 and 0.212 ug/L, exceeding its 2B
Standard of 0.012 ug/L. Based on data analysis it appears the detection of mercury is
originating from background/upstream conditions.
• Landfill gas monitoring was not performed at LG-1 due to unauthorized 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-5 and LG-6 (April 2022 event), both indicating 0.1 % methane, or 2% LEL.
A completed Environmental Monitoring Report Form is attached to this letter report.

Receipt
The samples were received on 4/15/2022 9:00 AM. Unless otherwise noted below, the samples arrived in good condition, and where
required, properly preserved and on ice. The temperature of the cooler at receipt was 2.50 C.
GC/MS VOA
Method 8260D: The continuing calibration verification (CCV) analyzed in batch 180-396317 was outside the method criteria for the
following analyte(s): 1, 1 -Dichloroethene. A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and
found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected
analyte(s) is considered estimated.
Method 8260D: The continuing calibration verification (CCV) analyzed in 180-396317 was outside the method criteria for the following
analyte(s): Dichloro-difluoromethane. As indicated in the reference method, sample analysis may proceed; however, any detection for the
affected analyte(s) is considered estimated.
Method 8260D: The continuing calibration verification (CCV) analyzed in batch 180-396426 was outside the method criteria for the
following analyte(s): 1,2-Dibromo-3-Chloropropane. A CCV standard at or below the reporting limit (RL) was analyzed with the affected
samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the
affected analyte(s) is considered estimated.
Method 8260D: The continuing calibration verification (CCV) analyzed in 180-396426 was outside the method criteria for the following
analyte(s): Acetone, Dichloro-difluoromethane, Chloromethane, 2-Hexanone, 1,1,2-Trichloro-1,2,2-trifluoroethane and Toluene-d8
(Surrogate). As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is
considered estimated.
Method 8260D: Internal standard (ISTD) response for TBA-d9 for the following samples in analytical batch 180-396426 was outside
acceptance criteria: MW-5 (180-136737-1) and SW-1 (180-136737-4). This ISTD does not correspond to any of the requested target
compounds reported from this analytical batch; therefore, the data have been reported.
Method 8260D: Surrogate Dibromofluoromethane recovery lower than expected for QC criteria. Samples reanalyzed for confirmation. MW-5
(180-136737-1) and SW-1 (180-136737-4)
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
GC Semi VOA
Methods 300.0, 9056A: The following sample was diluted to bring the concentration of target analytes within the calibration range: MW-4R
(180-136737-3). Elevated reporting limits (RLs) are provided. As stated in the SOP, due to the sample's conductivity reading, a dilution
was performed on the sample's initial analysis, which is an indication of the amount of anions present in the samples. Any non -detection
will have elevated reporting levels. Even though the target anions were not detected in the dilution analysis, this is the lowest possible
level of detection that can be obtained from the samples' matrix, because there are other high levels of non -target anions present in this
sample which would contaminate the IC system, & render it non -operational for hours or even days. As a result, all non -detected anion's
values are reported at these elevated reporting levels
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
Metals
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
General Chemistry
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
