Case Narrative Method: 6850 Analysis: Perchlorate Analysis SOP: LC-MS-CLO4 ALS WO ID(s): 1820868; 1821923

Client: ALS Laboratories (Houston, TX) Matrix: Water ELMS Batch (HBN): 2125 (220447)

General Set Information: There were two field samples in these Work Orders. The samples were analyzed for perchlorate. Method Summary: Each sample was prepared as noted below and analyzed using an Agilent 1100 LC/MSD system in select ion monitoring (SIM) mode at m/z 83 and 85, which corresponds to the loss of one oxygen atom from the perchlorate molecule. ChemStation software was used for instrument control and data analysis. The ion ratio of m/z 83 to 85 was used to positively identify the response peak as perchlorate. Quantitation was performed using the m/z 83 peak area. An internal standard (ISTD) of 18O labeled perchlorate was added to each sample to establish the perchlorate peak retention time and used in quantitation. Sample Preparation: A 10.0mL aliquot of each sample was transferred into a 15-mL centrifuge tube. 50µL of an 18O labeled perchlorate solution was added to each sample as an internal standard. The samples were then capped, vortexed, and filtered into autosampler vial using Phenex PES membrane 0.45µm Syringe filters. Holding Times: Holding times were met for all analyses. Dilutions: NA Method QC data: The method blank (LMB 613553) was less than 1/2 the CRDL. The recovery for the LCS (613554) was within acceptable parameters.

Page 12 of 88

00912973

MS/MSD Analysis: The matrix spike and matrix spike duplicate (MS/MSD) was performed on sample 1820868001 (Client ID: LH18/24-SP650_072618). The MS/MSD percent recoveries and relative percent difference (RPD) were within the performance limits. Instrument QC: Instrument initial and continuing calibrations were performed in accordance with published procedures. NC/CAR(s): NA Sample Calculation: Samples were reported in µg/L. Results were calculated in µg/L by the equation (A)x(B),

where: A = Analyte concentration from the standard curve (µg/L) B = Dilution performed at time of analysis Miscellaneous Comments: These samples were analyzed in accordance with the requirements found in the DOD QSM Version 5.1. Due to limitations of the Chemstation Software, some of the chromatographic peaks require manual integration. A manual integration was performed for datafile 07AUGD03.

Case Narrative Method: 6850 Analysis: Perchlorate Analysis SOP: LC-MS-CLO4 ALS WO ID(s): 1820868; 1821923

Client: ALS Laboratories (Houston, TX) Matrix: Water ELMS Batch (HBN): 2125 (220447)

General Set Information: There were two field samples in these Work Orders. The samples were analyzed for perchlorate. Method Summary: Each sample was prepared as noted below and analyzed using an Agilent 1100 LC/MSD system in select ion monitoring (SIM) mode at m/z 83 and 85, which corresponds to the loss of one oxygen atom from the perchlorate molecule. ChemStation software was used for instrument control and data analysis. The ion ratio of m/z 83 to 85 was used to positively identify the response peak as perchlorate. Quantitation was performed using the m/z 83 peak area. An internal standard (ISTD) of 18O labeled perchlorate was added to each sample to establish the perchlorate peak retention time and used in quantitation. Sample Preparation: A 10.0mL aliquot of each sample was transferred into a 15-mL centrifuge tube. 50µL of an 18O labeled perchlorate solution was added to each sample as an internal standard. The samples were then capped, vortexed, and filtered into autosampler vial using Phenex PES membrane 0.45µm Syringe filters. Holding Times: Holding times were met for all analyses. Dilutions: NA Method QC data: The method blank (LMB 613553) was less than 1/2 the CRDL. The recovery for the LCS (613554) was within acceptable parameters.

Page 10 of 86

00913095

MS/MSD Analysis: The matrix spike and matrix spike duplicate (MS/MSD) was performed on sample 1820868001 (Client ID: LH18/24-SP650_072618). The MS/MSD percent recoveries and relative percent difference (RPD) were within the performance limits. Instrument QC: Instrument initial and continuing calibrations were performed in accordance with published procedures. NC/CAR(s): NA Sample Calculation: Samples were reported in µg/L. Results were calculated in µg/L by the equation (A)x(B),

where: A = Analyte concentration from the standard curve (µg/L) B = Dilution performed at time of analysis Miscellaneous Comments: These samples were analyzed in accordance with the requirements found in the DOD QSM Version 5.1. Due to limitations of the Chemstation Software, some of the chromatographic peaks require manual integration. A manual integration was performed for datafile 07AUGD03.

Case Narrative Method: 6850 Analysis: Perchlorate Analysis SOP: LC-MS-CLO4 ALS WO ID(s): 1822951

Client: ALS Laboratories (Houston, TX) Matrix: Water ELMS Batch (HBN): 2130 (221315)

General Set Information: There was one field sample in this Work Order. The sample was analyzed for perchlorate. Method Summary: Each sample was prepared as noted below and analyzed using an Agilent 1100 LC/MSD system in select ion monitoring (SIM) mode at m/z 83 and 85, which corresponds to the loss of one oxygen atom from the perchlorate molecule. ChemStation software was used for instrument control and data analysis. The ion ratio of m/z 83 to 85 was used to positively identify the response peak as perchlorate. Quantitation was performed using the m/z 83 peak area. An internal standard (ISTD) of 18O labeled perchlorate was added to each sample to establish the perchlorate peak retention time and used in quantitation. Sample Preparation: A 10.0mL aliquot of each sample was transferred into a 15-mL centrifuge tube. 50µL of an 18O labeled perchlorate solution was added to each sample as an internal standard. The samples were then capped, vortexed, and filtered into autosampler vial using Phenex PES membrane 0.45µm Syringe filters. Holding Times: Holding times were met for all analyses. Dilutions: NA Method QC data: The method blank (LMB 615254) was less than 1/2 the CRDL. The recovery for the LCS (615255) was within acceptable parameters.

00913234

MS/MSD Analysis: The matrix spike and matrix spike duplicate (MS/MSD) was performed on sample 1822951001 (Client ID: LH18/25-SP650_081518). The percent recoveries and relative percent difference (RPD) were within the performance limits. Instrument QC: Instrument initial and continuing calibrations were performed in accordance with published procedures. NC/CAR(s): NA Sample Calculation: Samples were reported in µg/L. Results were calculated in µg/L by the equation (A)x(B),

where: A = Analyte concentration from the standard curve (µg/L) B = Dilution performed at time of analysis Miscellaneous Comments: These samples were analyzed in accordance with the requirements found in the DOD QSM Version 5.1. Due to limitations of the Chemstation Software, some of the chromatographic peaks require manual integration. Manual integration were performed for datafile 21AUGD02/03/06/10.

Case Narrative Method: 6850 Analysis: Perchlorate Analysis SOP: LC-MS-CLO4 ALS WO ID(s): 1824064; 1824071

Client: ALS Laboratories (Houston, TX) Matrix: Water ELMS Batch (HBN): 2136 (221835)

General Set Information: There two field samples in these Work Orders. The samples were analyzed for perchlorate. Method Summary: Each sample was prepared as noted below and analyzed using an Agilent 1100 LC/MSD system in select ion monitoring (SIM) mode at m/z 83 and 85, which corresponds to the loss of one oxygen atom from the perchlorate molecule. ChemStation software was used for instrument control and data analysis. The ion ratio of m/z 83 to 85 was used to positively identify the response peak as perchlorate. Quantitation was performed using the m/z 83 peak area. An internal standard (ISTD) of 18O labeled perchlorate was added to each sample to establish the perchlorate peak retention time and used in quantitation. Sample Preparation: A 10.0mL aliquot of each sample was transferred into a 15-mL centrifuge tube. 50µL of an 18O labeled perchlorate solution was added to each sample as an internal standard. The samples were then capped, vortexed, and filtered into autosampler vial using Phenex PES membrane 0.45µm Syringe filters. Holding Times: Holding times were met for all analyses. Dilutions: Samples 1824064001, 1824071001 and the MS/MSD failed the 50-150% method requirement for ISTD recovery. The samples and MS/MSD were re-analyzed and reported from 1:5 dilution. The reporting limits were adjusted accordingly. Method QC data: The method blank (LMB 616400) was less than 1/2 the CRDL. The recovery for the LCS (616401) was within acceptable parameters.

00913331

MS/MSD Analysis: MS/MSD was performed on sample 1824064001 (Client ID: LH18/24-SP650_082718). 5.0µl of Working Standard Solution Horizon ID 41828 was added to 10.0mL of sample preparation. MS/MSD failed the 50-150% method requirement for ISTD recovery so the sample was diluted 5x and reanalyzed. Spike target = 5.0µg/L. Effective spike target = 25.0µg/L Instrument QC: Instrument initial and continuing calibrations were performed in accordance with published procedures. NC/CAR(s): NA Sample Calculation: Samples were reported in µg/L. Results were calculated in µg/L by the equation (A)x(B),

where: A = Analyte concentration from the standard curve (µg/L) B = Dilution performed at time of analysis Miscellaneous Comments: These samples were analyzed in accordance with the requirements found in the DOD QSM Version 5.1. Due to limitations of the Chemstation Software, some of the chromatographic peaks require manual integration. Manual integrations were performed for datafile 29AUGPD6/7.

Case Narrative Method: 6850 Analysis: Perchlorate Analysis SOP: LC-MS-CLO4 ALS WO ID(s): 1824064; 1824071

Client: ALS Laboratories (Houston, TX) Matrix: Water ELMS Batch (HBN): 2136 (221835)

General Set Information: There two field samples in these Work Orders. The samples were analyzed for perchlorate. Method Summary: Each sample was prepared as noted below and analyzed using an Agilent 1100 LC/MSD system in select ion monitoring (SIM) mode at m/z 83 and 85, which corresponds to the loss of one oxygen atom from the perchlorate molecule. ChemStation software was used for instrument control and data analysis. The ion ratio of m/z 83 to 85 was used to positively identify the response peak as perchlorate. Quantitation was performed using the m/z 83 peak area. An internal standard (ISTD) of 18O labeled perchlorate was added to each sample to establish the perchlorate peak retention time and used in quantitation. Sample Preparation: A 10.0mL aliquot of each sample was transferred into a 15-mL centrifuge tube. 50µL of an 18O labeled perchlorate solution was added to each sample as an internal standard. The samples were then capped, vortexed, and filtered into autosampler vial using Phenex PES membrane 0.45µm Syringe filters. Holding Times: Holding times were met for all analyses. Dilutions: Samples 1824064001, 1824071001 and the MS/MSD failed the 50-150% method requirement for ISTD recovery. The samples and MS/MSD were re-analyzed and reported from 1:5 dilution. The reporting limits were adjusted accordingly. Method QC data: The method blank (LMB 616400) was less than 1/2 the CRDL. The recovery for the LCS (616401) was within acceptable parameters.

MS/MSD Analysis: MS/MSD was performed on sample 1824064001 (Client ID: LH18/24-SP650_082718). 5.0µl of Working Standard Solution Horizon ID 41828 was added to 10.0mL of sample preparation. MS/MSD failed the 50-150% method requirement for ISTD recovery so the sample was diluted 5x and reanalyzed. Spike target = 5.0µg/L. Effective spike target = 25.0µg/L Instrument QC: Instrument initial and continuing calibrations were performed in accordance with published procedures. NC/CAR(s): NA Sample Calculation: Samples were reported in µg/L. Results were calculated in µg/L by the equation (A)x(B),

where: A = Analyte concentration from the standard curve (µg/L) B = Dilution performed at time of analysis Miscellaneous Comments: These samples were analyzed in accordance with the requirements found in the DOD QSM Version 5.1. Due to limitations of the Chemstation Software, some of the chromatographic peaks require manual integration. Manual integrations were performed for datafile 29AUGPD6/7.

Case Narrative Method: 6850 Analysis: Perchlorate Analysis SOP: LC-MS-CLO4 ALS WO ID(s): 1824768; 1824771; 1824779; 1825466

Client: ALS Laboratories (Houston, TX) Matrix: Water ELMS Batch (HBN): 2138 (222588)

General Set Information: There four field samples in these Work Orders. The samples were analyzed for perchlorate. Method Summary: Each sample was prepared as noted below and analyzed using an Agilent 1100 LC/MSD system in select ion monitoring (SIM) mode at m/z 83 and 85, which corresponds to the loss of one oxygen atom from the perchlorate molecule. ChemStation software was used for instrument control and data analysis. The ion ratio of m/z 83 to 85 was used to positively identify the response peak as perchlorate. Quantitation was performed using the m/z 83 peak area. An internal standard (ISTD) of 18O labeled perchlorate was added to each sample to establish the perchlorate peak retention time and used in quantitation. Sample Preparation: A 10.0mL aliquot of each sample was transferred into a 15-mL centrifuge tube. 50µL of an 18O labeled perchlorate solution was added to each sample as an internal standard. The samples were then capped, vortexed, and filtered into autosampler vial using Phenex PES membrane 0.45µm Syringe filters. Holding Times: Holding times were met for all analyses. Dilutions: Sample 1824779001 was analyzed and reported from a 1:1,000 dilution. The reporting limit has been adjusted accordingly. Method QC data: The method blank (LMB 618015) was less than 1/2 the CRDL. The recovery for the LCS (618016) was within acceptable parameters.

MS/MSD Analysis: MS/MSD was performed on sample 1824771001 (Client ID: LH18/24-SP650_083018). 5.0µl of Working Standard Solution Horizon ID 41828 was added to 10.0mL of sample preparation. The percent recoveries and relative percent difference (RPD) were within the performance limits. Instrument QC: Instrument initial and continuing calibrations were performed in accordance with published procedures. NC/CAR(s): NA Sample Calculation: Samples were reported in µg/L. Results were calculated in µg/L by the equation (A)x(B),

where: A = Analyte concentration from the standard curve (µg/L) B = Dilution performed at time of analysis Miscellaneous Comments: These samples were analyzed in accordance with the requirements found in the DOD QSM Version 5.1. Due to limitations of the Chemstation Software, some of the chromatographic peaks require manual integration. Manual integrations were performed for datafile 12SEPPD02/03/13. The ion ratio of m/z 83 to 85 may fail at levels near the reported Detection Limit (DL). The 83/85 ion ratio failed for field sample 1824779001.

Case Narrative Method: 6850 Analysis: Perchlorate Analysis SOP: LC-MS-CLO4 ALS WO ID(s): 1824768; 1824771; 1824779; 1825466

Client: ALS Laboratories (Houston, TX) Matrix: Water ELMS Batch (HBN): 2138 (222588)

General Set Information: There four field samples in these Work Orders. The samples were analyzed for perchlorate. Method Summary: Each sample was prepared as noted below and analyzed using an Agilent 1100 LC/MSD system in select ion monitoring (SIM) mode at m/z 83 and 85, which corresponds to the loss of one oxygen atom from the perchlorate molecule. ChemStation software was used for instrument control and data analysis. The ion ratio of m/z 83 to 85 was used to positively identify the response peak as perchlorate. Quantitation was performed using the m/z 83 peak area. An internal standard (ISTD) of 18O labeled perchlorate was added to each sample to establish the perchlorate peak retention time and used in quantitation. Sample Preparation: A 10.0mL aliquot of each sample was transferred into a 15-mL centrifuge tube. 50µL of an 18O labeled perchlorate solution was added to each sample as an internal standard. The samples were then capped, vortexed, and filtered into autosampler vial using Phenex PES membrane 0.45µm Syringe filters. Holding Times: Holding times were met for all analyses. Dilutions: Sample 1824779001 was analyzed and reported from a 1:1,000 dilution. The reporting limit has been adjusted accordingly. Method QC data: The method blank (LMB 618015) was less than 1/2 the CRDL. The recovery for the LCS (618016) was within acceptable parameters.

12 of 97

00914220

MS/MSD Analysis: MS/MSD was performed on sample 1824771001 (Client ID: LH18/24-SP650_083018). 5.0µl of Working Standard Solution Horizon ID 41828 was added to 10.0mL of sample preparation. The percent recoveries and relative percent difference (RPD) were within the performance limits. Instrument QC: Instrument initial and continuing calibrations were performed in accordance with published procedures. NC/CAR(s): NA Sample Calculation: Samples were reported in µg/L. Results were calculated in µg/L by the equation (A)x(B),

where: A = Analyte concentration from the standard curve (µg/L) B = Dilution performed at time of analysis Miscellaneous Comments: These samples were analyzed in accordance with the requirements found in the DOD QSM Version 5.1. Due to limitations of the Chemstation Software, some of the chromatographic peaks require manual integration. Manual integrations were performed for datafile 12SEPPD02/03/13. The ion ratio of m/z 83 to 85 may fail at levels near the reported Detection Limit (DL). The 83/85 ion ratio failed for field sample 1824779001.

Case Narrative Method: 6850 Analysis: Perchlorate Analysis SOP: LC-MS-CLO4 ALS WO ID(s): 1826185; 1826186; 1826197; 1826550

Client: ALS Laboratories (Houston, TX) Matrix: Water ELMS Batch (HBN): 2144 (223442)

General Set Information: There were five field samples in these Work Orders. The samples were analyzed for perchlorate. Method Summary: Each sample was prepared as noted below and analyzed using an Agilent 1100 LC/MSD system in select ion monitoring (SIM) mode at m/z 83 and 85, which corresponds to the loss of one oxygen atom from the perchlorate molecule. ChemStation software was used for instrument control and data analysis. The ion ratio of m/z 83 to 85 was used to positively identify the response peak as perchlorate. Quantitation was performed using the m/z 83 peak area. An internal standard (ISTD) of 18O labeled perchlorate was added to each sample to establish the perchlorate peak retention time and used in quantitation. Sample Preparation: A 10.0mL aliquot of each sample was transferred into a 15-mL centrifuge tube. 50µL of an 18O labeled perchlorate solution was added to each sample as an internal standard. The samples were then capped, vortexed, and filtered into autosampler vial using Phenex PES membrane 0.45µm Syringe filters. Holding Times: Holding times were met for all analyses. Dilutions: Sample 1826197001 was analyzed and reported from a 1:1,000 dilution. Samples 1826185001, 1826186001/02 and 1826550001 failed the 50-150% method requirement for ISTD recovery. The samples were re-analyzed and reported from 1:10 dilutions. The reporting limits have been adjusted accordingly. Method QC data: The method blank (LMB 620036) was less than 1/2 the CRDL. The recovery for the LCS (620037) was within acceptable parameters.

00914335

MS/MSD Analysis: MS/MSD was performed on sample 1826185001 (Client ID: LH18/24-SP650_091318_AIX). 5.0µl of Working Standard Solution Horizon ID 41828 was added to 10.0mL of sample preparation. The parent sample and the MS/MSD were analyzed at 1:10 dilutions. The effective spike target was 50.µg/L. The percent recoveries and relative percent difference (RPD) were within the performance limits. Instrument QC: Instrument initial and continuing calibrations were performed in accordance with published procedures. NC/CAR(s): NA Sample Calculation: Samples were reported in µg/L. Results were calculated in µg/L by the equation (A)x(B),

where: A = Analyte concentration from the standard curve (µg/L) B = Dilution performed at time of analysis Miscellaneous Comments: These samples were analyzed in accordance with the requirements found in the DOD QSM Version 5.1. Due to limitations of the Chemstation Software, some of the chromatographic peaks require manual integration. A manual integration was performed for datafile 26SEPPD03.

The ion ratio of m/z 83 to 85 often fails at levels near or below the Limit of Detection (LODV). The ion ratio failed for the Limit of Detection Verification standards (LODV1,2 – 620913/20). Manual Integrations were performed for some of the Initial Calibration analyses (datafiles: 27SEPI01/02) along with datafiles 02OCTP02/03/15-19/22/23/25/27. .

MDL = Method Detection Limit, a statistical estimate of method/media/instrument sensitivity.RL = Reporting Limit, a verified value of method/media/instrument sensitivity.CRDL = Contract Required Detection LimitReg. Limit = Regulatory Limit.ND = Not Detected, testing result not detected above the MDL or RL.< This testing result is less than the numerical value.** No result could be reported, see sample comments for details.

U = Qualifier indicates that the analyte was not detected above the MDL.J = Qualifier Indicates that the analyte value is between the MDL and the RL. It is also used to indicate an estimated value fortentatively identified compounds in mass spectrometry where a 1:1 response is assumed.B = Qualifier indicates that the analyte was detected in the blank.E = Qualifier indicates that the analyte result exceeds calibration range.P = Qualifier indicates that the RPD between the two columns is greater than 40%.
