Dioxins refer to a group of toxic chemical compounds that share certain chemical structures and biological characteristics. Specifically, dioxins refer to 2,3,7,8-substituted dibenzo-p-dioxins and dibenzofurans (CDDs/CDFs) in this document. Dioxins are formed in the production of some chlorinated organic compounds, some herbicides and were a historic byproduct from chlorine bleaching of wood pulp. Adverse health effects from long term exposure to dioxins in excess of the maximum contaminant level (MCL) of 30 parts per quadrillion (ppq) in drinking water are known to cause reproduction difficulties and increase the risk of cancer (Mukerjee, 1985). The Pigeon River and the Waterville Lake were historically contaminated by dioxins from historic paper mill processing along the river. Over the past several years EPA, state governments, and industry have worked together to eliminate known and measurable industrial dioxin emissions. A maximum contaminant level goal (MCLG) for dioxin has been set at zero. To help determine if dioxins occur in the reservoir's surface waters and, if so, at what levels, sample analysis at trace level amounts of 0.013 ppq (parts per quadrillion) is needed. SESD utilized a high volume water sampler (Infiltrex 300®) in conjunction with XAD resin to obtain samples at trace levels. Field sampling procedures followed the Quality Assurance Protection Plan except as noted below (Little, 2014). 2.0 Study Area The Pigeon River flows northwesterly from Canton, North Carolina into Tennessee where it joins the French Broad River. The Pigeon River is impounded forming Waterville Lake by Walters Dam. Completed in 1930, Walters Dam is 180 feet tall and 800 feet long and feeds through an underground concrete tunnel 6.2 miles to the Duke Energy power house where it discharges at the confluence of Big Creek and reforms the Pigeon River flowing into Tennessee. Table 1 provides a list of sampling locations and access points. PR01 is located upstream of Evergreen Packing, previously Champion International, paper mill in Canton, NC. PRO2, PRO3, and PRO4 are downstream of the paper mill. PRO2 provided a riverine sample while PRO3 and PRO4 were within the Waterville Reservoir. Figure 1 and Figure 2 provide a map of the sampling locations and a detail of the lake samples, respectively.

The first Pigeon River sample (PRO1) was collected off Penland Street upstream of the Evergreen Packing plant and the Pigeon Street Bridge in Canton, NC on May 5, 2014. The second Pigeon River sample (PR02) was collected off of Iron Tree Drive in Clyde, NC on May 6, 2014. PR03 was collected at 270 Elkhound Road, Waynesville, NC on May 7, 2014. Duke Energy agreed to allow the use of their dock near the dam for sampling of PR04 on May 8, 2013. At PRO1 and PR02, both wadeable locations, sampling intakes were anchored at approximately mid -stream and mid -depth. A canoe was used to place a buoy and weight for mooring the sampling line at PR03. At station PR04 sampling intake was placed off the end of the dock. The Infiltrex 300® was assembled and operated from the shore at all sites in accordance with SESD Operating Procedure for Trace Organics Sampling Using an Infiltrex 300® High Volume Sampler (SESDPROC-502-R3, 2012). All field sampling equipment was checked out and tracked according to the SESD Operating Procedure for Equipment Inventory and Management (SESDPROC-108-R4, 2013).

The particulate (filter) and dissolved fractions (column) were analyzed separately for polychlorinated dibenzodioxins (PCDD) and polychlorinated dibenzofurans (PCDF) using a modified version of EPA Method 1613: Tetra-through-Octa Chlorinated Dioxins and Furans by Isotope Dilution HRGC/HRMS, Revision B (U.S. EPA, 1994), see Appendix A Axys Method Modification of 1613B for clarification. The Infiltrex 300® sampler consists of a metal frame which houses a positive displacement gear pump, a flow meter, a flow rate/total volume pumped display, a pressure gauge, control box, and two removable stainless steel canisters which hold glass fiber filters. Two stainless steel columns packed with XAD-2 were attached during sample collection. Teflon tubing was used for connections and the inlet and outlet. Figure 3 provides a schematic of flow through for the Infiltrex 300®. The unit is equipped with two glass fiber canisters for independent flow control, allowing for no down time if replacement of filters is required (Figure 3). Sample flow rates and total volume filtered are summarized in Table 2. These sampling rates combined with the XAD-2 resin allow for low level detections of dioxins (0.013 ppq). A system blank was conducted prior to the field investigation. The blank was obtained by running 1 liter of ultra -pure water through a decontaminated setup. The liter was recirculated 30 minutes at a flow rate of 1.1 L/min. Results were normalized to 1000 liters for comparison. No glass fiber filters were used in the field blank.

Data sondes were deployed to log at five minute intervals during the operation of the Infiltrex 300® and collect measurements of temperature, pH, specific conductance, dissolved oxygen and turbidity. Table 3 provides probe uncertainties for the data sonde used.

Glass fiber filters were placed in precleaned glass containers, capped and stored on frozen gel packs along with columns. TSS samples were collected in one liter polyethylene containers and placed on ice in a cooler separate from the columns immediately following collection. Upon return to SESD, glass fiber filters and XAD-2 resin columns were packed into coolers and shipped to the analytical laboratory. TSS samples were delivered to the custody room for distribution to the ASB laboratory. All samples were handled and custody maintained in accordance with the SESD Operating Procedure for Sample and Evidence Management (SESDPROC-005-R2, 2013) and following guidance from the Analytical Services Branch Laboratory Operations and Quality Assurance Manual (SESD Analytical Services Branch, 2014). 4.0 Results Analytical results from dioxin analysis are discussed below in Section 4.1. SESD lab results for TSS are discussed in Section 4.2 and in situ measurements in Section 4.3. 4.1 High Volume Sample Analysis Columns and filters were analyzed separately by Axys Analytical providing dissolved and particulate fractions, respectively, for dioxins and furans. Concentrations were reported as pg/L, SESD Project ID: 14-0123 Page 11 of 81 an equivalent representation of ppq. See Appendix B for further data, including reporting limits (RL) and surrogate recovery. The 2005 revised World Health Organization (WHO) Toxic Equivalency Factors (TEF) values for the dioxins and furans are a means for indicating the toxicity of dioxin, furan and PCB congeners (Van den Berg, 2006). TEFs for the dioxins and furans analyzed in this study are summarized in Table 4.

A system blank was collected by SESD and analyzed. Labeling of samples, chain of custody, sample collection and data recording was done in accordance with the SESD Operating Procedure for Field Sampling Quality Control (SESDPROC- 011-R4, 2013), SESD Operating Procedure for Sample and Evidence Management (SESDPROC- 005-R2, 2013), and SESD Operating Procedure for Trace Organics Sampling using an Infiltrex® 300 High Volume Sampler (SESDPROC-502-R3, 2012). With the exception of the stainless steel columns and glass fiber filters, all equipment that came in direct contact with the sample during collection was decontaminated at the SESD laboratory prior to use according to the procedures outlined in SESD Operating Procedure for Trace Organics Sampling Using an Infiltrex 300® High Volume Sampler (SESDPROC-502-R3, 2012). Columns were cleaned and packed with XAD-2 resin by the analytical laboratory. A system blank was collected prior to field sampling operations. XAD samples from the system blank were analyzed to ensure that no dioxin contaminants were present in the decontaminated equipment. As summarized in Table 16, analytes were not detected above the reporting limit or are best estimates at the lowest detectable range. All calibration standards, field equipment, field supplies and field consumables were maintained in accordance with SESD Operating procedure for Equipment Inventory and Management (SESDPROC- 108-R4, 2013). All data derived from SESD field measurements and sampling were reviewed, verified, validated and deemed usable in accordance with the SESD Operating Procedure for Report Preparation and Distribution (SESDPROC-003-R4, 2013).

The highest dissolved analyte detected was OCDD at PR03 with a concentration of 0.127 pg/L. The highest total concentration detected was for tetra -dioxins at PR02 with a concentration of 0.199 pg/L. The majority of the contaminants of interest appear to be bound in solids greater than one micron as particulate concentrations of dioxins and furans were higher than dissolved concentrations, except for TCDF at stations PR01 and PR04. Particulate concentrations for all analytes peaked at PR02, decreasing downstream with concentrations at PR04 returning to levels comparable to those at PRO1 as particulates most likely settled out of the water column.

The extract is concentrated and spiked with an isotopically labeled recovery (internal) standard. Analysis is performed using a high -resolution mass spectrometer coupled to a high resolution gas chromatograph equipped with a DB-5 capillary chromatography column (60 m, 0.25 mm i.d., 0.1 µm film thickness). A second column, DB-225 (30 m, 0.25 mm i.d., 0.15 µm film thickness), is used for confirmation of 2,3,7,8 —TCDF identification. All procedures are carried out according to protocols as described in EPA Method 1613B, with the significant modifications summarized below. The data are evaluated against QC criteria presented in Tables 1 and 2. Method Modifications: Section 2.1.2 Non -aqueous liquid from multiphase sample is combined with solid phase and extracted by Dean -Stark soxhlet. Section 7.2.1 Anhydrous sodium sulphate (Na2SO4) is purchased as powder form (not granular) and is baked overnight prior to use. There is no solvent rinse with dichlormethane. Section 7.10 The concentration of the labeled compound spiking solution is 100 ng/mL (except for OCDD which is 200 ng/mL) and the sample spiking volume is 20 µL. The resulting concentrations in the final extracts are specified in the method. Section 7.11 The concentration of the clean-up standard spiking solution is 10 ng/mL and the sample spiking volume is 20 µL. The resulting concentrations in the final extracts are specified in the method. Sections 7.13, 14.0, 15.0 An additional lower level calibration solution, 0.2 times the concentration of CS1, is prepared and included in the initial calibration series. Initial calibration is based on a six -point series. SESD Project ID: 14-0123 Page 40 of 81 Section 7.14 The concentration of the PAR spiking solutions is 0.2/1.0/2.0 ng/mL for tetra/penta, hexa, hepta, hexa/octas respectively and the spiking volume is 1 mL. The resulting final concentrations in the extracts are as specified in the method. Section 9.3.3, Table 7 Acceptance criteria for the percent recovery of surrogate standards in samples have been revised. Criteria that are higher than 130% have been lowered to 130%, as presented in Table 1. Section 11.5 Aqueous samples containing >1% visible solids are prepared and extracted using the same procedure as samples containing <1% visible solids. This involves extracting the solids by soxhlet and the filtrate by separatory funnel extraction and combining the extract from the two phases. Section 12.0 Samples with sufficiently low moisture content may be mixed with Na2SO4 and extracted using regular soxhlet apparatus in 80:20 toluene:acetone. Section12.4 The equilibrium time for the sodium sulfate drying step is that required to produce a dry, free flowing powder (minimum thirty minutes). This may be less than the 12-hour minimum specified in EPA 1613B. Section 12.5.1 Samples are spiked with cleanup standard right after extraction and before reduction; not spiked into the separatory funnels containing the extracts prior to the acid/base wash. Section 12.6.1.1 Rotary evaporator baths are maintained at 35°C. Mimic proofs are collected instead of collecting proofs each day and archiving. Section 13.0 Extracts may be cleaned up on silica, alumina and carbon chromatographic columns using a Fluid Management System (FMS) automated cleanup system. Section 13.7 Gravimetric lipid analysis is carried out on two subsamples of the extract. SESD Project ID: 14-0123 Page 41 of 81 Section14.0, 15.0, 16.0, Table 8, Table 9 M/Z channels 354/356 and 366/368 are used to confirm and quantify the native and surrogate penta-substituted dioxins, respectively; this change from the method's specification is made in the instrument method in order to avoid a persistent interference in the 356/358 and 368/370 M/Z channels. The theoretical raio for the P5CDD M/M+2 ions is 0.61; therefore, the acceptance range is 0.52-0.70. Section 15.3.5, Table 6 Acceptance criteria for calibration verification concentrations have been modified, as presented in Tablel, so that ranges do not exceed 70-130% of the test concentration. Section 17.0 Cone,— the concentration of target analytes, and the labeled compound concentrations and recoveries, are calculated using the equations below. These procedures are equivalent to those described in the method but are more direct.
