Subject: Semi -Annual Monitoring Report
BASF Former Industrial Landfill Facility
Permit # 11-02
Enka, North Carolina
Dear Ms. Drummond:
ELM Site Solutions (ELMSS), on behalf of BASF Corporation (BASF), herein submits an electronic
copy of the semi-annual sampling report for the above -referenced site. This letter report presents
results of the semi-annual sampling activities conducted on October 1-2, 2018, which constitutes
the second of two (2) sampling events for 2018. 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 SWA 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 (5) years.
Sampling results for the monitoring wells, surface water samples and surface seep (Seep-1) are
discussed below.
In addition to the groundwater samples outlined above, 10 landfill gas monitoring wells (LG-1
through LG-10 installed at the site in May 2010) were monitored on September 22, 2018 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 October 1-2, 2018 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 (2) 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 October 2018.
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 previous three (3) 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 previous three (3) sampling events. The alterations
to these wells were presumably conducted during the on -going grading operations at the site.
Neither BASF nor ELMSS were contacted prior to 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
October 2018 groundwater monitoring event. Relative groundwater elevations for MW-4R and
MW-5 as measured on October 1, 2018 are shown on Figure 1.
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 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 September 22, 2018. 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
Shealy Environmental Services, Inc. in West Columbia, South Carolina analyzed the groundwater
and surface water samples for Appendix I volatile organic compounds (VOCs) by EPA Method
8260B, 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. Due to the aforementioned alterations to
groundwater monitoring wells MW-3 and MW-6 discussed above, no samples were collected from
these wells. 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 in accordance with the above -referenced NCDEQ
correspondence. A copy of the analytical report is presented in Appendix C.
For data analysis, groundwater monitoring well results were compared to 15A NCAC 2L
Groundwater Standards, the regulatory basis established to determine groundwater quality.
Surface water results were compared to 15A NCAC 2B Surface Water Standards. Analytical results
are summarized in Table 3.
No organic constituents were detected above laboratory method reporting limits in any of the
groundwater monitoring wells or surface water samples during the October 2018 monitoring event.
For inorganic constituents, cobalt was detected in one (1) monitoring well (MW-5) at a concentration
(24.1 ug/L) which exceeded its 15A NCAC 2L Groundwater Standard of 1 ug/L. Vanadium was
detected in one (1) monitoring well (MW-5) at an estimated concentration (0.91 J ug/L) which
exceeded its 15A NCAC 2L Groundwater Standard of 0.3 ug/L.
As noted above, quarterly landfill gas monitoring events were conducted on September 22, 2018
for 10 landfill gas wells located near the waste boundary during the reporting period. All gas wells
exhibited 0% LEL through the reporting period. Current and historical landfill gas sampling data
are summarized in Table 4.
The following summarizes results and observations obtained during this reporting period:
• Groundwater samples were not collected from MW-3 and MW-6 due to unknown well
modifications.
• No organic constituents were detected above laboratory method reporting limits in any of
the groundwater or surface water samples during the October 2018 monitoring event.
• Cobalt was detected in one (1) monitoring well (MW-5) at a concentration (24.1 ug/L) which
exceeded its 15A NCAC 2L Groundwater Standard of 1 ug/L. It should be noted that
background soil samples were collected during the initial seep (adjacent to MW-5)

investigation 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. 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 monitoring may be due to mobilization of background metals from soil.
• Vanadium was detected in one (1) monitoring well (MW-5) at an estimated concentration
(0.91J) which exceeded its 15A NCAC 2L Groundwater Standard of 0.3 ug/L.
• No inorganic element concentrations detected in surface water exceeded their respective
15A NCAC 2B Standards during this monitoring event.
• All gas wells exhibited 0% LEL through the reporting period, which is consistent with
historical monitoring.

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
