On March 1, 20 I 0, operators at the Bingham Facility detected an unusual odor emanating from the septic tank of the permitted wastewater treatment system. EHS personnel were notified the next day (March 2, 2010) and began investigating, with the operators, to determine the source of the odor. The odor was strong in both the septic tank and the nearest wet well, and the odor registered at levels up to 30 parts per million on a photoionization detector (PID). On-site methods used to determine the chemical composition of the odor were inconclusive. That same day, EHS personnel and the wastewater treatment system operators investigated sewer cleanouts from both Bingham I (older building) and Bingham 2, and they detected no odor or elevated PID readings. Additionally, EHS personnel and the facility operators visually inspected Bingham I and 2 and interviewed employees at the facility in an attempt to discover the source of the odor; however, nothing conclusive was identified. EHS personnel and facility operators also inspected Bingham 3, which is under construction, as well as two manholes outside of Bingham 3. EHS personnel and facility operators determined that the manholes and visible piping were dry. The construction activities at Bingham 3 have involved installation of propylene glycol into the cooling system, installation of epoxy flooring, and finishing activities. The Bingham Facility is currently operating under a DENR Division of Water Quality (DWQ) Pump and Haul Permit (Permit No. WQ0034607). Under the Pump and Haul Permit, wastewater from the Bingham Facility is collected within the animal wastewater treatment plant and transported to the Orange Water and Sewer Authority (OWASA) Wastewater Treatment Plant located in Chapel Hill, North Carolina. Upon becoming aware of the odor from the septic system, EHS personnel ceased all pump and haul operations as of March 2, 2010. There is adequate storage capacity on-site to collect and retain the wastewater.

Subject Unusual Odor in Septic Tank The University of North Carolina at Chapel Hill (UNC) Bingham Facility (former Research Resource Facility)

Dear Mr Fleahman

I am writing in follow-up to your telephone conversation with Larry Daw on March 17 2010 regarding an unusual odor in the septic tank at the subject facility

On March 1 20 I 0 operators at the Bingham Facility detected an unusual odor emanating from the septic tank of the permitted wastewater treatment system EHS personnel were notified the next day (March 2 2010) and began investigating with the operators to determine the source of the odor The odor was strong in both the septic tank and the nearest wet well and the odor registered at levels up to 30 parts per million on a photoionization detector (PID) On-site methods used to determine the chemical composition of the odor were inconclusive

That same day EHS personnel and the wastewater treatment system operators investigated sewer cleanouts from both Bingham I ( older building) and Bingham 2 and they detected no odor or elevated PID readings Additionally EHS personnel and the facility operators visually inspected Bingham I and 2 and interviewed employees at the facility in an attempt to discover the source of the odor however nothing conclusive was identified

EHS personnel and facility operators also inspected Bingham 3 which is under construction as well as two manholes outside of Bingham 3 EHS personnel and facility operators determined that the manholes and visible piping were dry The construction activities at Bingham 3 have involved installation ofpropylene glycol into the cooling system installation of epoxy flooring and finishing activities

The Bingham Facility is currently operating under a DENR Division of Water Quality (DWQ) Pump and Haul Permit (Permit No WQ0034607) Under the Pump and Haul Permit wastewater from the Bingham Facility is collected within the animal wastewater treatment plant and transported to the Orange Water and Sewer Authority (OWASA) Wastewater Treatment Plant located in Chapel Hill North Carolina Upon becoming aware of the odor from the septic system EHS personnel ceased all pump and haul operations as of March 2 2010 There is adequate storage capacity on-site to collect and retain the wastewater

On March 2 2010 UNCs consultant McKim amp Creed (MampC) collected a water sample from the domestic wastewater system at the septic tank effulent pump station (referred to in the chain-of-custody documents as the post septic tank) EHS personnel requested expedited processing of these results (Attachment 1) which EHS received on the afternoon of March 4 2010 These results showed the presence of toluene and ethylene glycol

Following receipt of these results UNC and MampC determined that additional sampling would be conducted at the equalization basin of the animal wastewater system (referred to in the chain-of-custody documents as the Capetown system) in order to gain additional information regarding the constituents of concern (CoC) and to provide OW ASA with further data about the wastewater to be sent to OWASA This additional sampling was conducted on March 5 2010 UNC also requested expedited processing of these results (Attachment 2) and received them late on Tuesday March 9 2010 The delay in receipt of these results was due to analytical equipment problems at the laboratory

Upon review of the March 5 2010 sampling results UNC and MampC determined that further resampling was necessary because acetone was present in the samples and because UNC and MampC believed that the presence of acetone was a laboratory artifact To confirm that the acetone was a laboratory artifact UNC sent a part of the March 5 2010 sample to SGS North America Inc for analysis (Attachment 3)

On March 11 2010 MampC collected two samples from the equalization basin of the animal wastewater system and a composite sample of the septic tank Each sample was split and one part was sent to EnviroChem for analysis while the second part was sent to SGS for analysis in order to ensure the accuracy of the results UNC requested expedited processing of these results which UNC received on March 15 2010 (Attachment 4)

The main CoC identified in all of the samples included toluene ethylene glycol and propylene glycol which are components of the materials being utilized in the construction site of Building 3 Additionally these chemicals are not commonly used at the Bingham Facility Consequently UNC believes that the construction materials were the likely source of the CoCs The main construction activities have been completed and the floor drains have been covered to reduce the likelihood of a recurrence

On March 16 2010 UNC contacted Damon Forney the Operations Manager at OWASA to supply him with analytical data from the samples collected to date (including an analysis of samples (Attachment 5) taken on February 18-19 2010 which were collected to initiate UNCs evaluation of the wastewater treatment system) and to inquire whether OWASA could continue to accept the wastewater The following day OWASA stated that it could not receive the wastewater because of the concentration of toluene present in the wastewater

UNC has contracted with Clean Harbors to dispose of the wastewater and to determine how to clean out the wastewater system The current plan is to flushclean the wastewater piping from Building 3 remove contaminated water store it on-site in frac tanks and clean the septic tank

and basins in the wastewater system Clean Harbors initiated this process on Monday March 22 2010

Following containerization of the contaminated wastewater the material will be characterized for offsite disposal Once these activities are completed UNC plans to resume normal pump and haul activities

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and qnantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Qnantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Page 2: March 25, 2010: UNC report of chemical odor in septic tank · for offsite disposal. Once these activities are completed, UNC plans to resume normal pump and haul activities. Please

The University of North Carolina at Chapel HillUNC Department of Environment Health amp Safety lNv IR( )N rvllmiddot0middot1 1120 Estes Drive Ext CB 1650 l-11lTlmiddotI laquo 1f Y 9lgtJel Hill North Carolina_~]599l5c0_____

On March 2 2010 UNCs consultant McKim amp Creed (MampC) collected a water sample from the domestic wastewater system at the septic tank effulent pump station (referred to in the chain-of-custody documents as the post septic tank) EHS personnel requested expedited processing of these results (Attachment 1) which EHS received on the afternoon of March 4 2010 These results showed the presence of toluene and ethylene glycol

Following receipt of these results UNC and MampC determined that additional sampling would be conducted at the equalization basin of the animal wastewater system (referred to in the chain-of-custody documents as the Capetown system) in order to gain additional information regarding the constituents of concern (CoC) and to provide OW ASA with further data about the wastewater to be sent to OWASA This additional sampling was conducted on March 5 2010 UNC also requested expedited processing of these results (Attachment 2) and received them late on Tuesday March 9 2010 The delay in receipt of these results was due to analytical equipment problems at the laboratory

Upon review of the March 5 2010 sampling results UNC and MampC determined that further resampling was necessary because acetone was present in the samples and because UNC and MampC believed that the presence of acetone was a laboratory artifact To confirm that the acetone was a laboratory artifact UNC sent a part of the March 5 2010 sample to SGS North America Inc for analysis (Attachment 3)

On March 11 2010 MampC collected two samples from the equalization basin of the animal wastewater system and a composite sample of the septic tank Each sample was split and one part was sent to EnviroChem for analysis while the second part was sent to SGS for analysis in order to ensure the accuracy of the results UNC requested expedited processing of these results which UNC received on March 15 2010 (Attachment 4)

The main CoC identified in all of the samples included toluene ethylene glycol and propylene glycol which are components of the materials being utilized in the construction site of Building 3 Additionally these chemicals are not commonly used at the Bingham Facility Consequently UNC believes that the construction materials were the likely source of the CoCs The main construction activities have been completed and the floor drains have been covered to reduce the likelihood of a recurrence

On March 16 2010 UNC contacted Damon Forney the Operations Manager at OWASA to supply him with analytical data from the samples collected to date (including an analysis of samples (Attachment 5) taken on February 18-19 2010 which were collected to initiate UNCs evaluation of the wastewater treatment system) and to inquire whether OWASA could continue to accept the wastewater The following day OWASA stated that it could not receive the wastewater because of the concentration of toluene present in the wastewater

UNC has contracted with Clean Harbors to dispose of the wastewater and to determine how to clean out the wastewater system The current plan is to flushclean the wastewater piping from Building 3 remove contaminated water store it on-site in frac tanks and clean the septic tank

and basins in the wastewater system Clean Harbors initiated this process on Monday March 22 2010

Following containerization of the contaminated wastewater the material will be characterized for offsite disposal Once these activities are completed UNC plans to resume normal pump and haul activities

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and qnantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Qnantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (Tlq refers to substances which are not present in the list of target compounds Therefore not all TCs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search ofelectron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and qnantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March 121 2010

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

SGS Project Gl71-350 Project Name I0-2303

SGS North America Inc

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (Tlq refers to substances which are not present in the list of target compounds Therefore not all TCs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search ofelectron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and qnantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quanlilated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest Internal standard from the totalIon chromatogram TICs are Identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitatlon provided is an estimate

Comment Compound is reported as unknown if match probability is less than 70

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TlCs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (Tlq refers to substances which are not present in the list of target compounds Therefore not all TCs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search ofelectron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and qnantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quanlilated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest Internal standard from the totalIon chromatogram TICs are Identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitatlon provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (Tlq refers to substances which are not present in the list of target compounds Therefore not all TCs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search ofelectron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and qnantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are uot preseut in the list of target compounds Therefore not all TI Cs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and qnantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Qnantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (Tlq refers to substances which are not present in the list of target compounds Therefore not all TCs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search ofelectron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and qnantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quanlilated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest Internal standard from the totalIon chromatogram TICs are Identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitatlon provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are uot preseut in the list of target compounds Therefore not all TI Cs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate

March 121 2010

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

SGS Project Gl71-350 Project Name I0-2303

SGS North America Inc

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are uot preseut in the list of target compounds Therefore not all TI Cs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are uot preseut in the list of target compounds Therefore not all TI Cs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March 121 2010

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

SGS Project Gl71-350 Project Name I0-2303

SGS North America Inc

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are uot preseut in the list of target compounds Therefore not all TI Cs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

SGS North America Inc

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quanlilated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest Internal standard from the totalIon chromatogram TICs are Identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitatlon provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and qnantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Qnantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

SGS North America Inc

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and qnantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Qnantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quanlilated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest Internal standard from the totalIon chromatogram TICs are Identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitatlon provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quanlilated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest Internal standard from the totalIon chromatogram TICs are Identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitatlon provided is an estimate

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

bull Two waste water samples were accepted into the laboratory on March I 011 20 IO at 1415

for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be reported per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although both sample chromatograms display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quanlilated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest Internal standard from the totalIon chromatogram TICs are Identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitatlon provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate

SGS Project Gl71-350 Project Name I0-2303

SGS North America Inc

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Comment Compound is reported as unknown if match probability is less than 70

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TlCs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

SGS North America Inc

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment Compound is reported as unknown if match probability is less than 70

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TlCs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak height of the compound compared to that of the nearest internal standard from the total ion chromatograph TICs are identified and quantitated only if the peak height is equal or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

March IS 2010

bull Two waste water samples were accepted into the laboratory on March 11 h 20 IO at 1706 for analyses as indicated on the chain of custody The samples were received in good condition with a temperature of 20C

bull All extractions and analyses were completed within holding time limits with the following quality control exceptions

624 Analyses

bull Acetone was requested to be repotted per client communication Acetone is not part of the 624 continuing calibration report but is evaluated under the 8260 QC check

bull Although sample chromatograms for sample Cape Town display a peak eluting at the calibrated retention time for Acetone it is the opinion of the laboratory that this detection cannot accurately be reported as Acetone Due to a co-eluting non-target compound containing an abundance of ion 58 which is the secondary ion for Acetone this factor creates ion ratios that are inconsistent with the mass-spectral pattern of this compound

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate

Comment

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantitation provided is an estimate

Tentatively Identified Compound (TIC) refers to substances which are not present in the list of target compounds Therefore not all TICs are identified and quantitated using individual standards TIC listings are prepared utilizing a computerized library search of electron impact mass spectral data and evaluation of the relevant data by a mass spectral data specialist

Quantitation is accomplished by relative peak area of the compound compared to that of the nearest internal standard from the total ion chromatogram TICs are identified and quantitated only if the peak area is equal to or greater than 10 of that of the nearest internal standard Quantltation provided is an estimate
