ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

CASE NARRATIVE

Work Order Number I112097

SAMPLE RECEIPT

Samples were received at Frontier Global Sciences (FGS) on December 7th 2011 The samples were received intact on-ice with temperatures measured at 31 degrees Celsius

SAMPLE PREPARATION AND ANALYSIS

Per FGS standard operating procedure FGS-054 aqueous samples should be preserved with acid to pHlt2 for a minimwn of 16 hours at room temperature before preparation andor analysis to completely dissolve the metals adsorbed on the bottle walls Due to the clients requirement for rush sample data samples were preserved with acid to pHlt2 for approximately IO (ten) hours prior to preparation and analysis

Samples were prepared and analyzed for total metals in accordance with FGS-054EPA 163 8 with the exception ofthe preparation deviation noted above

Samples were prepared and analyzed for total mercury in accordance with EPA Method 163 lE

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

Wastewater flow data was estimated based on the actual number of tank trucks sent to the Utility and tanker capacity

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

Per FGS standard operating procedure FGS-054 aqueous samples should be preserved with acid to pHlt2 for a minimwn of 16 hours at room temperature before preparation andor analysis to completely dissolve the metals adsorbed on the bottle walls Due to the clients requirement for rush sample data samples were preserved with acid to pHlt2 for approximately IO (ten) hours prior to preparation and analysis

Samples were prepared and analyzed for total metals in accordance with FGS-054EPA 163 8 with the exception ofthe preparation deviation noted above

Samples were prepared and analyzed for total mercury in accordance with EPA Method 163 lE

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

Work Order Number I112097

SAMPLE RECEIPT

Samples were received at Frontier Global Sciences (FGS) on December 7th 2011 The samples were received intact on-ice with temperatures measured at 31 degrees Celsius

SAMPLE PREPARATION AND ANALYSIS

Per FGS standard operating procedure FGS-054 aqueous samples should be preserved with acid to pHlt2 for a minimwn of 16 hours at room temperature before preparation andor analysis to completely dissolve the metals adsorbed on the bottle walls Due to the clients requirement for rush sample data samples were preserved with acid to pHlt2 for approximately IO (ten) hours prior to preparation and analysis

Samples were prepared and analyzed for total metals in accordance with FGS-054EPA 163 8 with the exception ofthe preparation deviation noted above

Samples were prepared and analyzed for total mercury in accordance with EPA Method 163 lE

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

CASE NARRATIVE

Work Order Number I112097

SAMPLE RECEIPT

Samples were received at Frontier Global Sciences (FGS) on December 7th 2011 The samples were received intact on-ice with temperatures measured at 31 degrees Celsius

SAMPLE PREPARATION AND ANALYSIS

Per FGS standard operating procedure FGS-054 aqueous samples should be preserved with acid to pHlt2 for a minimwn of 16 hours at room temperature before preparation andor analysis to completely dissolve the metals adsorbed on the bottle walls Due to the clients requirement for rush sample data samples were preserved with acid to pHlt2 for approximately IO (ten) hours prior to preparation and analysis

Samples were prepared and analyzed for total metals in accordance with FGS-054EPA 163 8 with the exception ofthe preparation deviation noted above

Samples were prepared and analyzed for total mercury in accordance with EPA Method 163 lE

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

Wastewater flow data was estimated based on the actual number of tank trucks sent to the Utility and tanker capacity

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

Wastewater flow data was estimated based on the actual number of tank trucks sent to the Utility and tanker capacity

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

Wastewater flow data was estimated based on the actual number of tank trucks sent to the Utility and tanker capacity

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

CASE NARRATIVE

Work Order Number I112097

SAMPLE RECEIPT

Samples were received at Frontier Global Sciences (FGS) on December 7th 2011 The samples were received intact on-ice with temperatures measured at 31 degrees Celsius

SAMPLE PREPARATION AND ANALYSIS

Per FGS standard operating procedure FGS-054 aqueous samples should be preserved with acid to pHlt2 for a minimwn of 16 hours at room temperature before preparation andor analysis to completely dissolve the metals adsorbed on the bottle walls Due to the clients requirement for rush sample data samples were preserved with acid to pHlt2 for approximately IO (ten) hours prior to preparation and analysis

Samples were prepared and analyzed for total metals in accordance with FGS-054EPA 163 8 with the exception ofthe preparation deviation noted above

Samples were prepared and analyzed for total mercury in accordance with EPA Method 163 lE

ANALYTICAL AND QUALITY CONTROL ISSUES

There were no analytical difficulties experienced with analysis ofthese samples with the exceptions flagged in the report

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element

Wastewater flow data was estimated based on the actual number of tank trucks sent to the Utility and tanker capacity

ANALYTICAL NOTATION

FGD wastewater requires specialized analytical techniques to overcome matrix interference on some trace metals analysis Many analytical laboratories may be unaware of this We offer an excerpt below from EPAs web site and a link to their draft procedure that contains further guidance

LABORATORY ANALYSIS OF FLUE GAS DESULFURIZATION FOO) WASTEWATER

Wastewater from FGD systems can contain constituents that may interfere with certain laboratory analyses due to high concentrations of total dissolved solids (TDS) or the presence of elements known to cause matrix interferences EPA has observed that during inductively coupled plasma - mass spectrometry (ICP-MS) analysis of FGD wastewater certain elements commonly present in the wastewater may cause polyatomic interferences that bias the detection andor quantization of certain elements of interest These potential interferences may become significant when measuring trace elements such as arsenic and selenium at concentrations in the low parts-pershybillion range

As part of a recent sampling effort for the steam electric power generating effluent guidelines rulemaking EPA developed a standard operating procedure (SOP) that was used in conjunction with EPA Method 2008 to conduct ICP-MS analyses of FGD wastewater The SOP describes critical technical and quality assurance procedures that were implemented to mitigate anticipated interferences and generate reliable data for FGD wastewater EPA regulations at 40 CFR 1366 already allow the analytical community flexibility to modify approved methods to lower the costs of measurements overcome matrix interferences or otherwise improve the analysis The draft SOP developed for FGD wastewater takes a proactive approach toward looking for and taking steps to mitigate matrix interferences including using specialized interference check solutfons (ie a synthetic FGD wastewater matrix) EPAs draft SOP is being made available to laboratories contemplating ICP-MS analysis of FGD wastewater either for adoption as currently written or to serve as a framework for developing their own laboratory-specific SOPs Standard Operating Procedure Inductively Coupled PlasmaMass Spectrometry for Trace Element
