Huntersville, NC 28078 Project: Duke Asheville Plant (LIMS# J15060029) June 19, 2015 1. Sample Reception Page 13 of 38 Eight (8) aqueous samples were submitted for hexavalent chromium, selenium speciation, arsenic speciation, iron speciation, and manganese speciation analyses on May 28, 2015. All samples were received in acceptable condition on May 29, 2015 in a sealed container at 0.0°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. Sample fractions requesting hexavalent chromium, selenium speciation, arsenic speciation, and iron speciation analyses were field filtered by the client. Two containers were submitted for each client sample requesting manganese speciation, one field filtered fraction and one unfiltered fraction. 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 4°C, until the analyses could be performed. An aliquot of each sample requiring selenium speciation evaluation was decanted into a polypropylene centrifuge tube and each filtrate was stored in a secure, monitored cryofreezer (maintained at a temperature of -80°C) until selenium speciation analysis could be performed. An aliquot of each sample submitted for arsenic speciation analysis was decanted into a polypropylene centrifuge tube; all filtrates and original bottles were then stored in a secure, monitored refrigerator (maintained at a temperature of <6°C) 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 <6°C) until the analyses could be performed. Page 14 of 38 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 <6°C) 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. 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 Anal vsis 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. Selenium Speciation Analvsis 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. Arsenic Speciation Analysis by IC -ICP -CRC -MS An aliquot of each sample was filtered directly into a sealed autosampler vial. No further sample preparation was performed as a buffered EDTA solution was provided by Brooks Rand Labs for field -preservation of the submitted samples. 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(LI) 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). Page 15 of 38 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 5, 2015. An aliquot of each sample is 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. Selenium Speciation Analysis by IC -ICP -CRC -MS Each sample for selenium speciation analysis was analyzed by ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC -ICP -CRC -MS) on June 3, 2015. 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. Page 16 of 38 Arsenic Speciation Analysis by IC -ICP -CRC -MS Each sample was analyzed for arsenic speciation via ion chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC -ICP -CRC -MS) on June 4, 2015. Aliquots of each sample are injected onto an anion exchange column and eluted isocratically. The eluting arsenic 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 specific collision gas. Polyatomic interferences, due to their inherently larger size, collide more frequently with the collision gas and therefore may be separated from the analyte of interest via kinetic energy discrimination (KED). 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. Retention times for each eluting species are compared to known standards for species identification. Iron Speciation Analysis by Spectrophotometry All sample fractions submitted for iron speciation were analyzed for Fe(II) quantification on May 29, 2015. All sample fractions submitted for iron speciation were analyzed for Fe(III) quantification on June 18, 2015. The samples were analyzed for iron speciation 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 June 5, 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. Page 17 of 38 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 June 5-6, 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 (Q 1), 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 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. Preparation blanks were not analyzed for Fe(II) analysis. The preparation blanks were analyzed or Fe(III) analysis. All preparation blanks yielded non -detect results for total iron, demonstrating the absence of iron contamination due to the containers, the preservative employed, and the equipment used to collect the samples. Two client samples (MW -16A and MW -18D) yielded Mn(II) results greater than the value of the associated high calibration standard. A linear range verification standard was analyzed at 2000 µg/L. The Mn(II) recovery for the linear range verification standard was acceptable, at 100.1%, demonstrating that the linear range of the analytical platform extended to 2000 µg/L for Mn(II). All reported Mn(ll) results were less than 2000 µg/L with the dilutions at the instrument factored in, and thus were within the linear range demonstrated by the linear range verification standard. No corrective actions were necessary. For the Mn(II) analytical run the client sample, identified as MW -18D, was analyzed as the matrix quality control sample. The matrix spike sample and matrix spike duplicate sample (MS/MSD) spike recoveries for Mn(II) were below the lower control limit of 75%, at - 494.8% and -541.0%, respectively. The native Mn(II) concentration in the quality control sample was significantly greater than the spiking level. Acceptable spike recoveries are often not realized when the ambient level analyte concentration is greater than the spiking level. No qualification of data was necessary. 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. Page 18 of 38 For the Mn(IV) analysis the total and dissolved Mn results for the client sample, identified as MW -18D, were greater than the value of the associated high calibration standard. A linear range verification standard was analyzed at 500.0 µg/L. The Mn recovery for the linear range verification standard was acceptable, at 100.4%, demonstrating that the linear range of the analytical platform extended to 500.0 µg/L for Mn. All results were within the linear range demonstrated by the linear range verification standard. No corrective actions were necessary. 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 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 values for methylseleninic acid and selenomethionine are 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 values for arsenite, arsenate, and dimethylarsinic acid are generated using the standard deviation of replicate analyses of the lowest standard in the calibration curve. The eMDL for monomethylarsonic acid is calculated from the average eMDL of the three arsenic species contained in the calibration (i.e., arsenite, arsenate, and dimethylarsinic acid); the calibration and CCVs do not contain monomethylarsonic acid due to impurities in this standard which would bias the results for other arsenic species. The eMDL values for both Fe(II) and total recoverable iron were set at 1/3 the value of the associated reporting limit since the standard deviations associated with the replicate analyses of the lowest standard in the calibration curves were zero. 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.
