Subject: Semi -Annual Compliance Monitoring Report
BASF Former Industrial Landfill Facility
Permit # 11-02
Enka, Buncombe County, North Carolina
Dear Ms. Drummond:
ELM Site Solutions, on behalf of BASF Corporation, herein submits an electronic copy of the Semi -
Annual Compliance Monitoring Report for the above -referenced site. This letter report presents
results of sampling activities conducted on October 13, 2019, which constitutes the second 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) in 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 at the site 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, nine landfill gas
monitoring wells (LG-2 through LG-10 installed at the site in May 2010) were monitored on June
29, 2019 and September 25, 2019 during this reporting period. While 10 wells have been sampled
historically, 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. Gas monitoring results are also discussed below.
Attachments to this letter report include tables, figures, appendices, a completed Environmental
Monitoring Report Form and the laboratory EDD package.
FIELD ACTIVITIES
Field Investigation methods for this groundwater monitoring event were conducted in accordance
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 13, 2019 using low -flow techniques with a peristaltic pump. Water levels were
measured at each well prior to sampling using a Heron Instruments Dipper-T water level meter and
are presented on Table 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.
Two of the 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 for MW-3 was originally 30.16 feet below top of casing (btoc) and was 41.10 feet
btoc as measured during the October 2016 monitoring event. The total depth for MW-6 was
originally 41.18 feet btoc and was 22.20 feet btoc as measured during the October 2016 monitoring
event. The alterations to these wells were presumably conducted during site grading operations at
the time of damage. 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 well alterations. Therefore, no potentiometric contour map was created for
this October 2019 groundwater monitoring event. Relative groundwater elevations for MW-4R and
MW-5 as measured on October 13, 2019 are shown on Figure 1.
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 on Table 2.
As noted above, nine landfill gas monitoring wells (LG-2 through LG-10) were sampled on June 29,
2019 and September 25, 2019. LG-1 was destroyed at an unknown time by road construction

activities performed between March 2019 and June 2019. Landfill gas monitoring 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 designated 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 (a North Carolina certified laboratory) analyzed
the groundwater and surface water samples for Appendix I volatile organic compounds (VOCs) by
EPA Method 8260D, Appendix I metals by EPA Methods 602013, mercury by EPA Method 7470A,
sulfate by EPA Method 300.0 and total dissolved solids by SM 2540C-2011. Groundwater samples
were only collected from monitoring wells MW-4R and MW-5 due to the aforementioned alterations
to groundwater monitoring wells MW-3 and MW-6 discussed above. 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 (21- standard), the regulatory basis established to determine groundwater
quality. Surface water results were compared to 15A NCAC 213 Surface Water Standards for Class
C waters. No organic constituents were detected above laboratory method reporting limits in any
of the groundwater monitoring wells or surface water samples during the October 2019 monitoring
event. Monitoring well MW-5 had two inorganic (cobalt and sulfate) concentrations that exceeded
their respective groundwater standards. No other inorganic analyte concentrations detected in the
groundwater or surface water samples exceeded their respective standards. Detections are
discussed below. Analytical results are summarized on Table 3.
Cobalt was detected in MW-5 at a concentration of 0.0241 milligrams per liter (mg/L) exceeding its
2L standard of 0.001 mg/L. This concentration is on the same order of magnitude as the previous
(April 2019) sampling event and was detected at the same concentration as the October 2018
sampling event. Sulfate was detected in MW-5 at a concentration of 318 mg/L exceeding its 2L
standard of 250 mg/L. This concentration is on the same order of magnitude as the previous
sampling events (April 2019 and October 2018) which exhibited concentrations of 245 mg/L and
138 mg/L, respectively.
Landfill gas well sample results indicated all sampled gas wells exhibited 0% LEL for the June and
September monitoring events. The action limit for methane is >5% CHa by volume. Current and
historical landfill gas sampling data are summarized on Table 4.
The following summarizes results and observations obtained during this reporting period:

Ms. Jaclynne Drummond
Former BASF Closed Industrial Landfill (11-02) Compliance Monitoring Report
March 15, 2020
• Groundwater samples were not collected from MW-3 and MW-6, nor have these wells been
sampled since October 2016, due to unauthorized well modifications.
Cobalt was detected in one monitoring well (MW-5) at a concentration of 0.0241 mg/L which
exceeded its 2L standard of 0.001 mg/L. It should be noted that historical background soil
samples were collected during the 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 (December 2019). 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.
• Sulfate was detected in MW-5 at a concentration of 318 mg/L which exceeded its 2L
standard of 250 mg/L. This concentration is on the same order of magnitude as the previous
sampling event (April 2019 at 245 mg/L).
Landfill gas sampling was not performed at LG-1 due to its unauthorized destruction, likely
from road construction activities between March and June 2019. All remaining landfill gas
wells were sampled and exhibited 0% LEL at the June 2019 and September 2019
compliance sampling events for this reporting period. Results are 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
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
ENVIRONMENTAL, LLC BE LIABLE FOR INDIRECT, SPECIAL, CONSEQUENTIAL, OR INCIDENTAL DAMAGES INCLUDING, BUT NOT
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.
