Mr. Perkins, Attached is the report associated with four (4 ) aqueous samples submitted for total mercury and selenium speciation analysis on September 13 , 2013. The samples were received in a sealed cooler at -0. 1 ° C on September 17 , 2013. Selenium speciation analysis was performed via ionchromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICPCRC -MS). Mercury quantitation was performed via cold vapor inductively coupled plasma mass spectrometry (CV-ICP-MS). Any issues associated with the analysis are addressed in the following report. If you have any questions, please feel free to contact me at your convenience.

Sincerely,

Jeremy Maute Project Coordinator Applied Speciation and Consulting, LLC

## Applied Speciation and Consulting, LLC Report prepared for: Jay Perkins Duke Energy Analytical Laboratory Mail Code MGO3A2 (Building 7405) 13339 Hagers Ferry Rd. Huntersville, NC 28078 Project: Allen - FGD WWTS (Bi-Monthly Routine) (LIMS# J13090252)
October 1 , 2013

1. Sample Reception Three (3 ) aqueous samples were submitted for selenium speciation analysis on September 13 , 2013. Three (3 ) additional samples were submitted for total mercury quantitation. All samples were received in acceptable condition on September 17 , 2013 in a sealed container at -0. 1 ° C. All samples were received in a laminar flow clean hood, void of trace metals contamination and ultra-violet radiation, and were designated discrete sample identifiers. The 40mL borosilicate glass vials submitted fo r total mercury were preserved with bromine monochloride (BrCl) solution. The resulting samples were stored in a secure polyethylene container, known to be free from trace metals contamination, until the analyses could be performed. An aliquot of each sample requiring selenium speciation evaluation was filtered (0.45μm) and each filtrate w as stored in a secure, monitored cryofreezer (maintained at a temperature of -80 ° C) until selenium speciation analysis could be performed via ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP- CRC -MS).

2. Sample Preparation All sample preparation is performed in laminar flow clean hoods known to be free from trace metals contamination. All applied water for dilutions and sample preservatives are monitored for contamination to account for any biases associated with the sample results. Total Mercury Quantitation by CV -ICP- MS All samples and preparation blanks for total mercury quantitation were preserved with 2 % (v/v) BrCl. The resulting samples wereanalyzed for mercury via cold vapor inductively coupled plasma mass spectrometry (CVICP-MS).

## Selenium Speciation Analysis by IC -ICP-CRC- MS Prior to analysis, an aliquot of each sample was filtered with a syringe filter (0.45μm) and injected directly into a sealed autosampler vial. No further sample preparation was performed as any chemical alteration of a sample may shift the equilibrium of the system, resulting in changes in speciation ratios.

3. Sample Analysis All sample analysis is preceded by a minimum of a five-point calibration curve spanning the entire concentration range of interest. Calibration curves are performed at the beginning of each analytical day. All calibration curves, associated with each species of interest, are standardized by linear regression resulting in a response factor. All sample results are instrument blank corrected to account for any operational biases associated with the analytical platform. Prior to sample analysis, all calibration curves are verified using second source standard s which are identified as initial calibration verification standards (ICV). Ongoing instrument performance is identified by the analysis of continuing calibration verification standards (CCV) and continuing calibration blanks (CCB) at a minimum interval of every ten analytical runs. Total Mercury Quantitation by CV -ICP- MS The sample fractions for total mercury quantitation were analyzed by cold vapor inductively coupled plasma mass spectrometry (CV-ICP-MS) on September 20 , 2013 . Aliquots of each sample are reacted with a reductant in -line and transported to a gas-liquid separator . The volatile elemental mercury that is formed is then swept by a stream of argon gas into a radio frequency (RF) plasma where energy- tr ansfer processes cause desolvation, atomization, and ionization. The ions are extracted from the plasma through a differentially-pumped vacuum interface and separated on the basis of their mass- to -charge ratio (m/z) by a mass spectrometer. A solid-state detector detects ions transmitted through the mass analyzer and the resulting current is processed by a data handling system. Selenium Speciation Analysis by IC -ICP-CRC- MS Eachsample for selenium speciation analysis w as analyzed by ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP- CRC -MS) on September 21, 2013. An aliquot of each sample is injected onto an anion exchange column and mobilized by a basic (pH > 7) gradient. The eluting selenium species are then introduced into a radio frequency (RF) plasma where energy-transfer processes cause desolvation, atomization, and ionization. The ions are extracted from the plasma through a differentially-pumped vacuum interface and travel through a pressurized chamber ( CRC ) containing a reaction gas which preferentially reacts with interfering ions of the same target mass to charge ratios (m/z). A solid-state detector detects ions transmitted through the mass analyzer and the resulting current is processed by a data handling system. Retention times for each eluting species are compared to known standards for species identification.

## 4. Analytical Issues

The overall analyses went well and no significant analytical issues were encountered. All quality control parameters associated with these samples were within acceptance limits with the following exception: The selenite and selenocyanate results for the preparation blank identified as PBW4 were determined to be statistical outliers upon application of the Grubbs test. No selenium species were detected in any of the other blanks ( i.e. , preparation blanks and continuing calibration blanks) associated with this sample batch. The results for PBW4 h ave therefore been excluded from all calculations since these values are deemed to be unrepresentative of the preparation blanks and the submitted samples. The estimated method detection limits (eMDLs) for selenite, selenate, and selenocyanate are generated from replicate analyses of the lowest standard in the calibration curve. Not all selenium species are present in preparation blanks; therefore, eMDL calculations based on preparation blanks are artificially biased low. The eMDL for methylseleninic acid and selenomethionine is calculated from the average eMDL of selenite, selenate, and selenocyanate. The calibration does not contain methylseleninic acid or selenomethionine due to impurities in these standards which would bias the results for other selenium species. The eMDL for mercury has been calculated using the standard deviation of the preparation blanks preserved and analyzed concurrently with the submitted samples. If you have any questions or concerns regarding this report, please feel free to contact me. Sincerely,

Jeremy Maute Project Coordinator Applied Speciation and Consulting, LLC
