### June 23, 2011 Duke Energy ATTN: Jay Perkins Scientific Support-Laboratory 13339 Hagers Ferry Road Huntersville NC 28078 jcperkins@duke-energy.com labcustomer@duke-energy.com
RE: Project DUK-HV1101 Client Project: J11060177 Dear Mr. Perkins, On June 14, 2011, Brooks Rand Labs (BRL) received three (3) flue gas desulfurization (FGD) waste water samples and three (3) corresponding field blanks. Samples were logged-in for total mercury (Hg) analysis and were received, prepared, analyzed, and stored according to BRL SOPs and EPA methodology. The results were blank-corrected as described in the calculations section of the applicable SOP(s) and may be evaluated using adjusted reporting limits to account for sample aliquot size. Please refer to the Sample Results page for sample-specific detection limits and other details. The three field blank samples produced detectable results. All results were however less than the method defined control limit of 0.5 ng/L and were therefore considered insignificant sources of contamination. All quality assurance criteria were satisfied, and all data was reported without additional qualification, aside from concentration qualifiers. BRL, an accredited laboratory, certifies the reported results of all analyses for which BRL is NELAP accredited meet all NELAP requirements. For more details, see the Report Information page of the report. Please feel free to contact us if you have any questions regarding this report.
Sincerely,

Tiffany Stilwater Jen Hartmann Project Manager Jr. Project Manager tiffany@brooksrand.com jen@brooksrand.comProject ID: DUK-HV1101

### Common Abbreviations

These qualifiers are based on those previously utilized by Brooks Rand, Ltd., those found in the EPA SOW ILM03.0, Exhibit B, Section III, pg. B-18, and the USEPA Laboratory Data Validation Functional Guidelines for Evaluating Inorganic Analyses; USEPA; July 2002. These supersede all previous qualifiers ever employed by BRL. Detected by the instrument, the result is > the MDL but ≤ the MRL. Result is reported and considered an estimate. B E An estimated value due to the presence of interferences. A full explanation is presented in the narrative. H Holding time and/or preservation requirements not met. Result is estimated. J Estimated value. A full explanation is presented in the narrative. J-M Duplicate precision (RPD) for associated QC sample was not within acceptance criteria. Result is estimated. J-N Spike recovery for associated QC sample was not within acceptance criteria. Result is estimated. M Duplicate precision (RPD) was not within acceptance criteria. Result is estimated. N Spike recovery was not within acceptance criteria. Result is estimated. R Rejected, unusable value. A full explanation is presented in the narrative. U Result is ≤ the MDL or client requested reporting limit (CRRL). Result reported as the MDL or CRRL. X Result is not BLK-corrected and is within 10x the absolute value of the highest detectable BLK in the batch. Result is estimated. 

### Field Quality Control Samples Please be notified that certain EPA methods require the collection of field quality control samples of an appropriate type and frequency; failure to do so is considered a deviation from some methods and for compliance purposes should only be done with the approval of regulatory authorities. Please see the specific EPA methods for details regarding required field quality control samples.

Jay Perkins Duke Energy Analytical Laboratory Mail Code MGO3A2 (Building 7405) 13339 Hagers Ferry Rd. Huntersville, NC 28078 (704) 875-5 245 Project: Allen - FGD WWTS (Bi-Weekly Sampling) (LIMS # J11060177) Dear Mr. Perkins, Attached is the report associated with four (4 ) aqueous samples submitted for selenium speciation analysis on June 13 , 2011. The samples were received in a sealed cooler at 6.9 o 

## C on June 14 , 2011. Selenium speciation analysis was performed via ion chromatography inductively coupled plasma dynamic reaction cell mass spectrometry (IC-ICP-DRC-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,

Ben Wozniak Project Manager 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-Weekly Sampling) (LIMS # J11060177) June 16, 201 1

1. Sample Reception Four (4 ) aqueous samples in 125mL HDPE bottles (provided by Applied Speciation and Consulting) were su bmitted for selenium speciation analysi s on June 13 , 2011 . The samples were received on June 1 4, 2011 in a sealed co ntainer at 6.9 o 

## C. Applied Speciation and Consulting strongly recommends that samples submitted for selenium speciation analysis remain at a temperature of ≤6 o 

## C to maintain sample integrity prior to analysis. The samples were received in a laminar flow clean hood void of trace metals contamination and ultra-violet radiation. Upon reception, the samples were designated discrete sample identifiers. An aliquot of each sample was filtered (0.45μm) and these filtrates were stored in a secure, monitored cryofreezer (maintained at a temperature of -80 o 

## C) until selenium speciation analysis could be performed via ion chromatography inductively coupled plasma dynamic reaction cell mass spectrometry (IC-ICP-DRC-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. Selenium Speciation Analysis by IC -ICP-DRC

- 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 the samples may shift the equilibrium of the system resulting in changes in speciation ratios.

## 3. Sample Analysis

All sample analysis is precluded 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 usin g 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 minimal interval of every ten analytical runs. Selenium Speciation Analysis by IC -ICP-DRC

- MS All samples for selenium speciation analysis were analyzed by ion chromatography inductively coupled plasma dynamic reaction cell mass spectrometry (IC- IC P-DRC-MS) on June 14 , 2011 . 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 (DRC) containing a specific reactive 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 very well and no analytical issues were encountered. All sample results have been corrected in accordance with the continuing calibration verification recoveries to account for perceived instrument drift. All quality control parameters associated with these samples were within acceptance limits. 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. If you have any questions or concerns regarding this report, please feel free to contact me. Sincerely,

Ben Wozniak Project Manager Applied Speciation and Consulting, LLC
