Subject: Semi -Annual Monitoring Report
BASF Former Industrial Landfill Facility
Permit # 11-02
Enka, North Carolina
Dear Ms. Drummond:
ELM Site Solutions, on behalf of BASF Corporation, herein submits an electronic copy of the semi-
annual compliance sampling report for the above -referenced site. This letter report presents results
of the semi-annual sampling activities conducted on April 5, 2019, which constitutes the first of two
sampling events for 2019. The approved groundwater monitoring network consists of MW-3, MW-
4R, MW-5 and background well MW-6. The monitoring network also includes surface water sample
locations SW-1 and DW-2 from Hominy Creek. In a letter dated November 4, 2010, the North
Carolina Department of Environmental Quality (NCDEQ) Solid Waste Section requested the
collection of an additional surface water sample from a seep area in conjunction with the semi-
annual groundwater sampling events for a minimum of five years. Sampling results for the
monitoring wells, surface water samples and surface seep (Seep-1) are discussed below.
In addition to the groundwater and surface water samples outlined above, 10 landfill gas monitoring
wells (LG-1 through LG-10, installed at the site in May 2010) were monitored on December 26,
2018 and March 9, 2019 during this reporting period. Gas monitoring results are also discussed
below.
A completed Environmental Monitoring Report Form follows this letter report.

FIELD ACTIVITIES
Field Investigation methods for this groundwater 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 from the site were
collected on April 5, 2019 using low -flow techniques with a peristaltic pump. Water levels were
measured at each well prior to sampling using a Testwell water level meter (Table 1).
Two of the groundwater monitoring wells (MW-3 and MW-6) were altered between the October
2016 and April 2017 monitoring events and were therefore not sampled in April 2019. Specifically,
the total depth for MW-3 was originally 30.16 feet below top of casing (btoc). The total depth for
MW-3 is now 41.10 feet btoc, as measured during the last three sampling events. Additionally, the
total depth for MW-6 was originally 41.18 feet btoc. The total depth for MW-6 is now 22.20 feet
btoc, as measured during the last three sampling events. The alterations to these wells were
presumably conducted during historical grading operations for re -development at the site. Neither
BASF nor ELMSS were contacted regarding any modifications to these wells. Top of casing
elevations are currently unknown for groundwater monitoring wells MW-3 and MW-6 due to the
alterations made to these wells. Therefore, no potentiometric contour map was created for the April
2019 groundwater monitoring event. Relative groundwater elevations for MW-4R and MW-5 as
measured on April 5, 2019 are shown on Figure 1.
Monitoring well purging was accomplished by using a variable speed peristaltic pump with the
pumping rate adjustable to equal the approximate recharge rate of the well. Indicator parameters
of pH, temperature, specific conductivity, turbidity, dissolved oxygen and oxidation-reduction
potential (ORP) were measured regularly during purging with a Horiba U-52 water quality meter
until the measured values stabilized. This `low -flow' method targets the collection of groundwater
samples that have the least total suspended solid count obtainable without filtering in the field, thus
giving a more accurate indication of dissolved constituents present in the aquifer. Groundwater
sample collection record sheets are provided in Appendix A.
Surface water samples were collected directly from Hominy Creek by filling pre -preserved
laboratory sample containers. The seep sample (Seep-1) was collected from a 4-inch pipe located
at the base of the seep area. Surface water sample locations are shown on Figure 2. Water
quality parameters for the monitoring wells, surface water locations and seep at the time of
sampling are presented in Table 2.
As noted above, 10 landfill gas monitoring wells were sampled on December 26, 2018 and March
9, 2019. Well locations are presented on Figure 3. Percent lower explosive limit (% LEL)
measurements and other applicable parameters (i.e., % methane by volume, % oxygen and %
carbon dioxide) were recorded at the landfill gas monitoring wells using a calibrated Landtec GEM
2000 instrument. Landfill gas sample collection record sheets are provided in Appendix B.

SAMPLING RESULTS
Eurofins Lancaster Laboratories in Lancaster, PA analyzed the groundwater and surface water
samples for Appendix I volatile organic compounds (VOCs) by EPA Method 8260D, Appendix I
metals by EPA Methods 6020B, mercury by EPA Method 7470A, sulfate by EPA Method 300.0 and
total dissolved solids by SM 2540C-2011. Due to the aforementioned alterations to groundwater
monitoring wells MW-3 and MW-6 discussed above, no samples were collected from these wells
(i.e., groundwater samples were only collected from monitoring wells MW-4R and MW-5). Surface
water samples were collected from Hominy Creek in upgradient location SW-1 and downgradient
location DW-2, as well as the seep location (Seep-1). The surface seep sample was only analyzed
for Appendix I VOCs. A copy of the analytical report is presented in Appendix C.
For data analysis, groundwater monitoring well results were compared to the 15A NCAC 2L
Groundwater Standards (2L Standards), the regulatory basis established to determine groundwater
quality. Surface water results were compared to 15A NCAC 2B Surface Water Standards for Class
C waters. Analytical results are summarized in Table 3.
No organic constituents were detected above their respective groundwater or surface water
standard during the April 2019 monitoring event except for 1,4-dioxane. MW-5 had a 1,4-dioxane
concentration of 8.6 micrograms per liter (ug/L), which exceeded its respective 2L Groundwater
Standard of 3 ug/L. The concentration of 1,4-dioxane was below detectable levels at all monitoring
wells sampled during the October 2018 semi-annual event (i.e., the first event that included analysis
for 1,4 dioxane). Correspondence received from the Solid Waste Section of the NCDEQ indicates
sampling for 1,4-dioxane was not, and is not, required. As such, BASF does not intend to continue
analyzing groundwater or surface water samples for 1,4-dioxane.
No inorganic constituents were detected above their respective groundwater or surface water
standard during the April 2019 monitoring event except for Cobalt. MW-5 had a Cobalt
concentration of 15.1 ug/L, which exceeded its respective 2L Standard of 1 ug/L. This concentration
marks a decrease since the October 2018 sampling event, when a cobalt concentration of 24.1
ug/L was identified in MW-5.
As noted above, quarterly landfill gas monitoring events were conducted on December 26th 2018
and March 9th, 2019 for 10 landfill gas wells located near the waste boundary during the reporting
period. All gas wells exhibited 0% LEL for the December monitoring event. During the March
sampling event, gas wells LG-1, LG-2, LG-6, LG-7, and LG-10 exhibited 0.4% CHa by volume
(0.02% LEL), and LG-3, LG-4, LG-5, LG-8, and LG-9 exhibited 0.3% CHa by volume (0.015%LEL).
The action limit for methane is >_5% CHa by volume. Current and historical landfill gas sampling
data are summarized in Table 4.
The following summarizes results and observations obtained during this reporting period:

Ms. Jaclynne Drummond
Monitoring Report— Permit 11-02
July 17, 2019
• Groundwater samples were not collected from MW-3 and MW-6 due to unknown well
modifications.
• 1,4-dioxane was detected above its respective 2L Standard in MW-5. Correspondence
received from the Solid Waste Section of the NCDEQ indicates sampling for 1,4-dioxane
was not, and is not, required. As such, BASF does not intend to continue analyzing
groundwater or surface water samples for 1,4-dioxane.
• Cobalt was detected above its respective 2L Standard in MW-5. It should be noted that
background soil samples were collected during the initial 2010 seep investigation (adjacent
to MW-5) 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. Oxidation Reduction Potential (ORP)
measurements in MW-5 indicated the presence of a reducing environment potentially
mobilizing background metals from soils. Some, if not all, of the cobalt detected during this
monitoring event may be due to mobilization of background metals from soil.
• All gas wells exhibited 0% LEL through the December 2018 monitoring event, which is
consistent with historical monitoring. All gas wells exhibited between 0.015-0.02% LEL
during the March 2019 monitoring event. All results are below action levels.

ppm parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg) or one gram per million grams. For
aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/1), because one liter of water has a weight
very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter per liter of gas.
ppb parts per billion
Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight
basis concentration to approximate the value present in a similar sample without moisture. All other results are reported on an
as -received basis.
Analytical test results meet all requirements of the associated regulatory program (i.e., NELAC (TNI), DoD, and ISO 17025) unless
otherwise noted under the individual analysis.
Measurement uncertainty values, as applicable, are available upon request.
Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the
collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be
meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held
responsible for sample integrity, however, unless sampling has been performed by a member of our staff.
This report shall not be reproduced except in full, without the written approval of the laboratory.
Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as "analyze immediately" are not performed within
15 minutes.
WARRANTY AND LIMITS OF LIABILITY - In accepting analytical work, we warrant the accuracy of test results for the sample as submitted.
THE FOREGOING EXPRESS WARRANTY IS EXCLUSIVE AND IS GIVEN IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR
IMPLIED. WE DISCLAIM ANY OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING A WARRANTY OF FITNESS FOR
PARTICULAR PURPOSE AND WARRANTY OF MERCHANTABILITY. IN NO EVENT SHALL EUROFINS LANCASTER LABORATORIES

LIMITED TO, DAMAGES FOR LOSS OF PROFIT OR GOODWILL REGARDLESS OF (A) THE NEGLIGENCE (EITHER SOLE OR
CONCURRENT) OF EUROFINS LANCASTER LABORATORIES ENVIRONMENTAL AND (B) WHETHER EUROFINS LANCASTER
LABORATORIES ENVIRONMENTAL HAS BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. We accept no legal
responsibility for the purposes for which the client uses the test results. No purchase order or other order for work shall be accepted by
Eurofins Lancaster Laboratories Environmental which includes any conditions that vary from the Standard Terms and Conditions, and
Eurofins Lancaster Laboratories Environmental hereby objects to any conflicting terms contained in any acceptance or order submitted by
client.
