RE: Copper and Zinc WER Confirmation Study — Final Report Submittal
Dear Sir or Madam:
I am pleased to submit the final report for a copper and zinc water effect ratio (WER) confirmation study
conducted on behalf of the Union County Public Works Twelve Mile Creek Water Reclamation Facility
(WRF).
This confirmation study was required by the facility's NPDES permit effective July 1, 2021, in order to
determine if the WER values derived in 2005/2006 for copper and zinc were still appropriate for the Twelve
Mile Creek WRF final effluent discharge. The original WER values derived were 2.79 for copper and 2.35
for zinc.
On February 22, 2023, a WER confirmation study was conducted using the same test species and study
plan as the 2005/2006 study. The confirmation study produced copper WER values of 3.953 (total) and
3.488 for (dissolved). The zinc WER values were 3.538 (total) and 3.111 (dissolved). These WER values
provide confirmation that the 2005/2006 WERs remain appropriate for the Twelve Mile Creek WRF.
If you need additional information regarding the report, please feel free to contact me at [phone], or

CONFIRMATION OF COPPER AND ZINC WATER-EFFECT RATIO FOR
THE UNION COUNTY TWELVE MILE CREEK WATER RECLAMATION FACILITY
WAXHAW, NORTH CAROLINA
FEBRUARY 22, 2023
Section 1: Executive Summary
Union County Public Works operates the Twelve Mile Creek Water Reclamation Facility (WRF)
under discharge permit #NC0085359. As a condition of the renewed permit, Twelve Mile Creek
WRF must provide verification of previously determined site-specific criteria for copper and zinc. In
coordination with Hazen and Sawyer and BT Solutions, LLC, Union County is seeking to conduct a
confirmation Water Effect Ratio (WER)study with copper and zinc for the Twelve Mile Creek WRF
in accordance with 15A NCAC 02B, Water Quality Standards for Surface Waters and Interim
Guidance on Determination and Use of Water-Effect Ratios for Metals (EPA 1994). Appendix F of
the Interim Method provides guidance on conducting WERs using multiple metals.
A combined copper and zinc WER study was conducted in 2005 by Shealy Environmental Services,
Inc., of Columbia, South Carolina. The study consisted of three (3) test sets conducted with the
invertebrate, Ceriodaphnia dubia(primary species),and one (1)test set with Pimephales promelas
(confirmation species). The study resulted in dissolved WER values of 2.79 (geometric mean of
dissolved copper WERs)and 2.35(geometric mean of dissolved zinc WERs).These WER values were
used to adjust North Carolina's default hardness-derived Water Quality Criteria (WQC) and derive
site-specific WQC. The site-specific WQC were then used to evaluate the need for copper and zinc
permit limits.
This report provides the study details and documentation for a copper and zinc Water-Effect Ratio
(WER) confirmation study conducted in accordance with EPA 823-B-94-001, Interim Guidance on
Determination and Use of Water-Effect Ratios for Metals (Appendix F). Toxicity test procedures
adhered to Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to
Freshwater and Marine Organisms, Fifth Edition, EPA 821-R-02-012. A study plan based on these
EPA guidance documents was developed by BT Solutions, LLC, and Hazen and Sawyer. It was
submitted to the North Carolina Department of Environmental Quality (NCDEQ) for review. On
January 18, 2022, an email was received from NCDEQ stating that the confirmation proposal was
approved with the following requirements:
1. Complete a confirmation study by conducting one set of WER Labwater and Simulated
Stream side-by-side tests using the same testing procedures as in the original study.
2. The permittee must also confirm that the effluent data for the previous permit cycle
remained within the range expected for the original study and the facility has consistently
complied with all toxicity testing requirements in the current permit.
The WER confirmation procedure was performed on February 22, 2023, using sample collected
February 20-21, 2023. The WERs determined using Ceriodaphnia dubia were 3.953/3.488 for
total/dissolved copper and 3.538/3.111 for total/dissolved zinc. These WER values confirm the
original values obtained in the 2005 study.

Section 2: Site and Sample Description
2.1 Weather and Twelve Mile Creek WRF Sampling Conditions
Weather conditions were monitored for Waxhaw, North Carolina, for two (2) weeks prior to the
sampling event. The conditions are recorded and are provided in Appendix A. A recent rain event
that totaled approximately '/< inch ended 48 hours prior to the sample initiation date, and the
receiving stream appeared to be clear with very little suspended sediment. The total suspended
sediment (TSS) concentration measured in the receiving stream at the time of collection was 12
mg/L.
According to WRF personnel,the WRF was operating normally during the sampling period.Table 1
provides a summary of the Twelve Mile Creek WRF permit limits and results during sampling.
Carbonaceous biochemical oxygen demand (CBOD) was 5.38 mg/L, TSS was 4.0 mg/L, pH was 7.2
SU and total nitrogen was <0.1 mg/L. All parameter measurements were within permitted
discharge limits.

2.2 Final Effluent Sample Collection
The sample chain of custody is available in Appendix A.
Sample collection procedures were conducted by BT Solutions, LLC.The compositor unit was fitted
with PTFE tubing which was rinsed with nitric acid and high purity de-ionized water prior to use. A
glass collection jar was also acid washed and rinsed prior to use. A PVC strainer was deployed
instead of the traditional metal strainer to prevent metal contamination. Analysis of a field blank
which was collected by pumping de-ionized water through the sampling unit resulted in <1 µg/L
copper and<5 µg/L zinc.
The temperature of the effluent at compositor initiation was 14.9°C and the pH was 7.2 SU. The
compositor was programmed to collect three (3) gallons of effluent in 15-minute intervals for 24
hours.The compositor program was initiated at 9:20 am on February 20, 2023.
At the end of the 24-hour compositing period,the sample was harvested from the compositor unit
and placed in containers. The compositor program terminated at 9:20 am, and sample was
harvested at 9:30 am on February 21, 2023. The effluent sample was poured into containers and

any air space over the effluent surface was removed.All effluent samples were double-bagged and
placed in coolers on ice for transport.
2.3 Receiving Stream Sample Collection
Receiving stream samples were collected as grab samples from a location upstream(approximately
50 feet) of the discharge point at 9:50 am on February 20, 2023. The pH of the river at sample
collection was 7.5 SU, and the water temperature was 13.1°C. Samples were collected with a
sampler with an extension so that sediments were not disturbed.The samples were double-bagged
p p gg
and placed in coolers on ice for transport.
Flow of the river was measured at the upstream collection location,using a Global Water flow probe
(FP101). After all water samples were collected and pH/temperature recorded, the river was
transected with a measuring tape with ends affixed at each bank. The flow meter was used to
determine flow at one(1)foot subsections.The probe was slowly moved vertically through the flow
from surface to bottom for 30 seconds to obtain an average flow for that subsection. A second
technician recorded the depth and flow for each subsection. Each subsection flow was calculated
as the average flow times the area of the subsection. The average for each subsection was added
to obtain the total river flow of 24 MGD (37 cfs),which is between the average flow of 72.7 cfs and
the winter 7Q10 of 1.5 cfs. Documentation of river flow is provided in Appendix A.
Samples were transported on ice to the ETS laboratory in Asheville, NC. They were received by
laboratory personnel at 12:36 pm on February 21, 2023. The cooler temperature was 2.2°C upon
laboratory receipt.
Section 3: Toxicity Test Procedures
3.1 Copper and Zinc Primary Stock
The copper source for the WER study was copper sulfate pentahydrate (CuSO4*5H2O)and the zinc
source was zinc chloride (ZnCl2). A primary stock solution was prepared by dissolving 0.9823 g
CuSO4*5H2O and 5.2109 g ZnCl2 in 250 mL deionized water. The nominal concentration of this stock
solution was 1 g/L copper and 10 g/L zinc.This stock was used to prepare all copper and zinc spiked
test treatments.
3.2 LABWATER Test Solutions
Synthetic laboratory dilution water (LABWATER) was prepared according to the procedure for
obtaining reconstituted water found in Section 7 of EPA 820-R-02-012, Methods for Measuring the
Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms.
A LABWATER sub-stock was prepared by diluting 1 ml of the primary stock to 1000 mL synthetic
water. Test solutions were prepared by combining the sub-stock with un-spiked synthetic water to
achieve nominal concentrations of 2.4/24, 3.7/37, 5.7/57, 8.8/88, 13.5/135, 21/210, and 32/320
µg/L as copper/zinc.

Page 4 of I
An aliquot of each LABWATER test solution was preserved with nitric acid for total copper and zinc
analysis. A separate aliquot was filtered at 0.45 µm and preserved with nitric acid for dissolved
copper and zinc analysis.The remaining aliquot of each solution was used for toxicity testing.
3.3 SIMSTREAM Test Solutions
SIMSTREAM was created by first screening the receiving stream water for organisms that could
compete for food or prey on the test organisms. The screened receiving stream water was mixed
with final effluent to create a SIMSTREAM of 80% receiving stream water and 20% Twelve Mile
Creek WRF final effluent.
A SIMSTREAM sub-stock was prepared by diluting 1 ml of the primary stock to 1000 mL prepared
SIMSTREAM. Test solutions were prepared by combining the sub-stock with un-spiked SIMSTREAM
to achieve nominal concentrations Of 5.7/57, 8.8/88, 13.5/135, 21/210, 32/320, 49/490, and
75/750 µg/L as copper/zinc.
An aliquot of each SIMSTREAM test solution was preserved with nitric acid for total copper and zinc
analysis. A separate aliquot was filtered at 0.45 µm and preserved with nitric acid for dissolved
copper and zinc analysis.The remaining aliquot of each solution was used for toxicity testing.
3.4 Bioassay Procedures
Bioassay procedures adhered to EPA Test Method 2002.0(EPA 2002a).A laboratory dilution water
control treatment was performed with each bioassay.An un-spiked SIMSTREAM control treatment
was also included with the SIMSTREAM bioassay. Reference toxicant data for the test organisms
used in the bioassay is provided in Appendix B with the toxicity test report from ETS.
Each test treatment consisted of 4 test chambers with 5 C. dubia each. Test organisms were fed
2 hours prior to test initiation,but no food was provided in the actual test solutions. Test organisms
were cultured in-house and were<24 hours old at test initiation. Test organisms were introduced
into all test chambers by 9:07 am on February 22, 2023. Dissolved oxygen, pH, and temperature
were measured for each test concentration at test initiation. The test board was placed in an
incubator set at a temperature of 25+1°C.
At 24 hours, the test board was removed from the incubator. D.O., pH, and temperature were
recorded for each test concentration. Mortality was recorded,and the test board placed back into
the incubator.
The toxicity tests were terminated on February 24, 2023, at 9:05 am. Dissolved oxygen, pH, and
temperature were measured for each test concentration at test termination. Mortality was
recorded, and all test solutions were filtered at 0.45 microns and preserved with nitric acid for
dissolved copper and zinc analysis.

Section 5: Water-Effect Ratio Calculation
5.1 Copper WER Calculation for the Twelve Mile Creek WRF
LCso values were determined using both nominal and measured copper concentrations. The
Trimmed Spearman-Karber test (ToxCalc v5.0.32) was used to determine 48-hour LCso values for
total and dissolved copper in the C. dubia LABWATER and SIMSTREAM tests.
The LCso for total copper in the LABWATER test with C.dubia was 6.3 µg/L. Since it is important that
the LCso values being used to calculate the WER represent the same hardness,the LABWATER LCso
was normalized from the reported hardness of 86 mg/L to the SIMSTREAM hardness of 57 mg/L
using the published slope for copper of 0.9422, (EPA 2009). The normalized value became 4.3 µg/L
total copper. The C. dubia LCso value for dissolved copper was 6.3 µg/L, and was normalized to 4.3
µg/L.
The LCso for total copper in the SIMSTREAM test with C. dubia was 17.0 µg/L and for dissolved
copper was 15.0 µg/L.
The Water-Effect Ratio (WER) was calculated by dividing the SIMSTREAM LCso by the normalized
LABWATER LCso. The total copper WER value for the study conducted February 22, 2023, with
C. dubia, was 3.953. The dissolved copper WER for the study was 3.488.

The hWER (highest flow WER) was calculated for copper. The hWER may be used to provide an
environmentally conservative estimate of the design-flow WER.The hWER for copper is 13.98.
The following calculations were used to determine the hWER:
HCME=[(CMC)(WER)(eFLOW+uFLOW)I—[(uCONC)(uFLOW)),
eFLOW
hWER=(HCME)(eFLOWdf)+(uCONCdf)(uFLOWdf),
(CMC) (eFLOWdf+uFLOWdf)
where:
CMC=the national or recalculated CCC that is to be adjusted
eFLOW=the flow of the effluent during the sampling event
uFLOW=the upstream flow of the receiving stream during the sampling event
uCONC=the upstream copper or zinc concentration in the receiving stream sample
eFLOWdf=effluent flow at design-flow conditions
uFLOWdf=upstream flow at design-flow conditions
uCONCdf=concentration of copper or zinc upstream at design-flow conditions,(if`zeros,the hWER
will be environmentally conservative).
5.2 Zinc WER Calculation for the Twelve Mile Creek WRF
LCso values were determined using both nominal and measured zinc concentrations. The Trimmed
Spearman-Karber test (ToxCalc v5.0.32) was used to determine 48-hour LCso values for total and
dissolved zinc in the C. dubia LABWATER and SIMSTREAM tests.
The LC50 for total zinc in the LABWATER test with C.dubia was 69.8 µg/L. Since it is important that
the LC50 values being used to calculate the WER represent the same hardness,the LABWATER LCso
was normalized from the reported hardness of 86 mg/L to the SIMSTREAM hardness of 57 mg/L
using the published slope for zinc of 0.8473, (EPA 2009). The normalized value became 49.26 µg/L
total zinc. The C. dubia LCso value for dissolved zinc was 65.3 µg/L, and was normalized to 46.09
µg/L.
The LC50 for total zinc in the SIMSTREAM test with C. dubia was 174.3 µg/L and for dissolved zinc
was 143.4 µg/L.
The Water-Effect Ratio (WER) was calculated by dividing the SIMSTREAM LC50 by the normalized
LABWATER LC50. The total zinc WER value for the study conducted February 22,2023,with C. dubia,
was 3.538. The dissolved zinc WER for the study was 3.111.
