Huntersville, NC 28078 980-875-5848 Project: Duke Energy Progress Mayo (LIMS# J15060909) Ms. Kendall, Attached is the revised report associated with nine (9) aqueous samples submitted for hexavalent chromium, iron speciation, and manganese speciation analyses on June 23, 2015. The samples were received in two sealed coolers at 0.3°C and 0.0°C on June 24, 2015. This report has been revised to correct date analyzed values and significant figures that were reported incorrectly in the initial report. The Fe(III) result for the client sample MW-16D was a detectable result, not a non-detect as reported in the original report. Correcting the significant figures used rendered slightly altered values for Mn(IV) results associated with the client samples ABMW-4BR and ABMW-2. The EDD format has also been corrected to conform to the EDD design requested. No other changes have been made to this report. Hexavalent chromium analysis was performed by ion chromatography inductively coupled plasma dynamic reaction cell mass spectrometry (IC-ICP-DRC-MS). All samples requesting iron speciation analysis were analyzed by spectrophotometry. Mn(II) analysis was performed via ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP- CRC-MS). Mn(IV) analyses were performed via digestion and subsequent analysis by inductively coupled plasma triple quadrupole mass spectrometry (ICP-QQQ-MS). Any issues associated with the analyses are addressed in the following report. If you have any questions, please feel free to contact me at your convenience. Sincerely, Jeremy Maute Project Manager Brooks Rand Labs, LLC Page 13 of 35 Brooks Rand Labs, LLC Report prepared for: Peggy Kendall Duke Energy Analytical Laboratory Mail Code MGO3A2 (Building 7405) 13339 Hagers Ferry Rd. Huntersville, NC 28078 Project: Duke Energy Progress Mayo (LIMS# J15060909) August 13, 2015 1. Sample Reception Nine (9) aqueous samples were submitted for hexavalent chromium, iron speciation, and manganese speciation analyses on June 23, 2015. The sample was received in acceptable condition on June 24, 2015 in two sealed containers at temperatures of 0.3°C and 0.0°C. The client requested that the sample name for the client sample MW3BR (LIMS ID: 2015021304) should be changed to MW3 (LIMS ID: 2015021304). The chain of custody form reflects the sample ID as MW3BR (LIMS ID: 2015021304); however, no results were reported using this sample ID. In accordance with the client’s instructions, the sample ID MW3 (LIMS ID: 2015021304) was used to report results for this sample. 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. An aliquot of each sample submitted for hexavalent chromium analysis was decanted into a clean polypropylene tube. All hexavalent chromium sample fractions were stored in a secure refrigerator maintained at a temperature of 4oC, until the analyses could be performed. The sample fractions requesting iron speciation analysis were stored in a secure, monitored refrigerator (maintained at a temperature of ≤6oC) until the analyses could be performed. An aliquot of each filtered sample submitted for manganese speciation analysis was decanted into a polypropylene centrifuge tube for Mn(II) analysis. These fractions were stored in a secure, monitored refrigerator (maintained at a temperature of ≤6oC) until the analyses could be performed. Subsequently, the original bottles (filtered and unfiltered fractions) intended for Mn speciation were preserved to pH < 2 with concentrated HNO3 and then stored in a secure polyethylene container, known to be free from trace metals contamination, until the digestion could be performed. Page 14 of 35 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. Hexavalent Chromium 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 a sample may shift the equilibrium of the system, resulting in changes in speciation ratios. Iron Speciation Analysis by Spectrophotometry No sample preparation was required as a de- gassed HCL solution was provided by Brooks Rand Labs for field-preservation of the submitted samples. Manganese Mn(II) Analysis by IC-ICP-CRC-MS An aliquot of each sample was filtered (0.45µm) directly into an autosampler vial for Mn(II) analysis. No additional sample preparation was performed as any chemical alteration of the samples may shift the equilibrium of the system resulting in changes in speciation ratios. Manganese Mn(IV) Analysis by ICP-QQQ-MS Each filtered and unfiltered sample submitted for Mn speciation analysis was preserved with 1% HNO3 (v/v) upon sample receipt. Each sample fraction was then further digested on a hotblock apparatus with aliquots of 50% HNO3 (v/v) and 50% HCl (v/v), in accordance with the digestion procedure specified in EPA Method 200.8. All resulting sample digests were analyzed for total manganese via inductively coupled plasma triple quadrupole mass spectrometry (ICP-QQQ-MS). 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 standards 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. Hexavalent Chromium Analysis by IC-ICP-DRC-MS Each sample for hexavalent chromium analysis was analyzed by ion chromatography inductively coupled plasma dynamic reaction cell mass spectrometry (IC-ICP-DRC-MS) on June 24, 2015. An aliquot of each sample is Page 15 of 35 injected onto an anion exchange column and mobilized by a basic (pH > 7) gradient. The eluting chromium 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 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. Iron Speciation Analysis by Spectrophotometry All samples submitted for Fe speciation quantification were analyzed on June 24, 2015, and in accordance with the scientifically accepted method outlined by: Stookey, L.L., (1970). “Ferrozine - A new spectrophotometric reagent for iron”, Anal.Chem., 42:779-81. Manganese Mn(II) Analysis by IC-ICP-CRC-MS All samples for Mn(II) analysis were analyzed by ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP-CRC-MS) on July 6, 2015. Aliquots of each sample are injected onto an anion exchange column and mobilized by an acidic (pH < 7) gradient. An ion pairing agent provides a dynamic ion exchange mechanism for the cationic manganese species on the chromatographic column. The differences in the affinity of manganese species towards the ion pair agent and the column results in separation. 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. Manganese Mn(IV) Analysis by ICP-QQQ-MS All samples submitted for Mn speciation quantitation were analyzed by inductively coupled plasma triple quadrupole mass spectrometry (ICP-QQQ-MS) on July 28, 2015. Aliquots of each sample digest are 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 an initial quadrupole (Q1), which filters the target masses prior to their entrance into a second chamber. The second chamber contains specific reactive gasses or collision gasses that preferentially react either with interfering ions of the same target mass to charge ratios (m/z) or with the target analyte, producing an entirely different mass to charge ratio (m/z) which can then be differentiated Page 16 of 35 from the initial interferences. The ions then exit the collision/reaction cell into and additional quadrupole (Q2). A solid-state detector detects ions transmitted through the mass analyzer, on the basis of their mass-to-charge ratio (m/z), and the resulting current is processed by a data handling system. 4. Analytical Issues No significant analytical issues were encountered. All quality control parameters associated with the samples were within acceptance limits. The total recoverable Fe concentrations of samples MW-13BR, MW-16S, ABMW-3, ABMW-2 were slightly less than the associated Fe(II) concentrations. The relative percent differences between the results were 1.8%, 0.5%, 23%, and 1.8%, meeting the criteria for duplicate precision. All iron present should be considered to be in the Fe(II). The Fe(III) calculations were reported as non-detectable at the level of the eMDL. Mn(IV) is quantified by analyzing the water samples for total Mn and dissolved Mn. Mn(IV) is operationally defined as the difference between the filtered and unfiltered total Mn concentrations, since it is thermodynamically favored to be in the form of a precipitate. The estimated method detection limit (eMDL) for hexavalent chromium is generated from replicate analyses of the lowest standard in the calibration curve. The eMDL values for Fe(II) and total recoverable Fe were set at 5 based on the sensitivity of the instrument. The eMDL for Mn(II) has been generated from replicate analyses of the lowest standard in the calibration curve. The eMDL values for Mn(IV) been calculated using the standard deviation of the method blanks prepared and analyzed concurrently with the submitted samples.
