Dear Mr. Perkins, Attached is the report associated with one (1 ) aqueous sample submitted for permanganate and persulfate analyses on February 2 1 , 2012

. The samples were received in a sealed cooler at - 0.3 ° C on February 2 2 , 2012

## 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: HA PS/MACT Testing Belews Creek (LIMS # J1202034 2 )

March 6 , 2012

1. Sample Reception One (1 ) aqueous sample in two 125mL HDPE bottles and two 125mL borosilicate glass bottles (provided by Applied Speciation and Consulting) was submitted for permanganate and persulfate analyses on February 2 1 , 2012 . The sample w as received on February 2 2 , 2012 in a sealed co ntainer at -0.3 ° C. The sample was received in a laminar flow clean hood, void of trace metals contamination and ultra-violet radiation, and was designated a discrete sample identifier. All sample containers were placed in a secure refrigerator maintained at a temperature of 4 o 

## C until analysis could be performed.

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.

## O 8 -2 

## and MnO 4 - 

## Analysis by Spectrophotometry Prior to analysis, an aliquot of each sample was filtered with a syringe filter (0.45μm). Permanganate standards of known concentrations were filtered using the identical filtration apparatus to confirm that filtration does not induce loss of the target analyte. Filtration is a requirement for samples containing suspended solids due to the light scattering properties of particulates.

## 3. Sample Analysis

All sample analysis is preceded by a minimum of a four-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 minimal interval of every ten analytical runs.
MnO 4 - 

## Analysis by Spectrophotometry Each sample for permanganate analysis w as analyzed by spectrophotometry on February 29, 2012 . An aliquot of each sample was transferred to a cuvette with a 1cm light path. The permanganate complex was quantified by measuring the light absorbance at a wavelength of 545nm.
S 2 

## O 8 -2 

## Analysis by Spectrophotometry Each sample for persulfate analysis was analyzed by spectrophotometry on March 1, 2012. An aliquot of each sample was transferred to a 15mL polyethylene centrifuge tube. A starch iodide solution was added to each sample which induces conversion of iodide to I 2(aq) 

## . The I 2 

## complex then reacts with starch to form a blue complex which is measured at a wavelength of 525nm.
4. Analytical Issues The permanganate and persulfate recoveries for the matrix spike and matrix spike duplicate were below the control limit of 75%. The target analytes are efficient oxidizing agents which are amenable to reaction with most compounds. The low recoveries confirm that the sample matrix does not support the existence of strong oxidizing agents such as permanganate or persulfate. Approximately 2 minutes passed between the time of amending the sample matrix with the spikes and measurements which suggests that the low sample concentrations are not attributed to the variable of sample holding times. If you have any questions or concerns regarding this report, please feel free to contact me. Sincerely,

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 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 minimal interval of every ten analytical runs. Selenium Speciation Analysis by IC -ICP-CRC- MS Each sample for selenium speciation analysis w as analyzed by ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP- CRC -MS) on February 23, 2012. 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 hydrogen 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.
Re tention 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 this sample 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.
