RE: Project DUK

- HV1 201 Client P roject : J13010488 Dear Mr. Perkins, O n February 1, 2013 , Brooks Rand Labs ( BRL ) received three(3 ) wastewater sample and three (3 ) corresponding field blanks. An aliquot was removed from each sample bottle and filtered into a separate container designed for dissolved mercury (Hg) analysis. The sample volume from the original container was logged

- in for total Hg analysis . All samples were received, prepared, analyzed, and stored according to BRL SOPs and EPA methodology. Data used for regulatory purposes has a 24 hour filtration holding time requirement. Non

regulatory purposed data has a 48 hour filtration holding time. The samples were received outside of the non

- regulatory requirement holding time and were qualified H

. The results were blank

- corrected as described in the calculations section of the relevant SOP and may have been evaluated using reporting limits that have been adjusted to account for sample aliquot size. Please refer to the Sample Results page for sample

- specific MDLs, MRLs, and other details. The results of continuing calibration blanks CCB7, CCB8, CCBC, and CCBD were greater than 10 pg of Hg. All bracketed samples were re

- analyzed for confirmation. The analysis of the first method blank was determined to be a Grubb’s outlier with a result of 0.73 ng/L. The result was omitted and all sample results were method blank

- corrected by the average of the three remaining method blank results. All data was reported without additional qualification, aside from concentration qualifiers, and a ll associated q uality control sample results met the acceptance cr iteria. 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 me if you have any questions. Sincerely,

## 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 Wastewater

– Nietering (January 2013

– Test Burn) (LIMS #J13010488 )
February 12, 2013

1. Sample Reception Four (4 ) aqueous samples in125mL HDPE bottles (provided by Applied Speciation and Consulting) were submitted for selenium speciation analysis on January 31, 2013 . The samples were received on February 1 , 201 3 in a sealed container at -0. 5 °C. The samples were received in a laminar flow clean hood, void of trace metals contamination and ultra-violet radiation, and were designated discrete sample identifiers. An aliquot of each sample was filtered (0.45μm) and each filtrate w as 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 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. 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 an 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 correctedto 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. Selenium Speciation Analysis by IC-ICP-CRC-MS Eachsample for selenium speciation analysis w asanalyzed by ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP- CRC -MS) on February 9, 2013. Analiquot of each sample isinjected 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 the 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.

## The laboratory control sample (LCS) recoveries for methylseleninic acid and

selenomethionine were elevated (132.2% and 130.2%, respectively). The speciation ratios identify that the referenced selenium species are relatively non-contributory with respect to the other selenium species present in the samples. Since the perceived elevated responses for methylseleninic acid and selenomethionine had negligible impact on the reported results no corrective action was taken. If you have any questions or concerns regarding this report, please feel free to contact me. Sincerely,

Russell Gerads Vice President Applied Speciation and Consulting, LLC
