Re Sediment and Water Sampling Memo ndash Twickenham Pond

Project No 20-202649

Introduction

Groundwater Environmental Management Services Inc (GEMS) has been retained by The

Municipal Infrastructure Group (TMIG) to collect and analyze representative water and sediment

samples taken from Twickenham Pond The project site is located within Twickenham Park east

of Bathurst Street just north of Canyon Hill Avenue in Richmond Hill Ontario

Field Sample Collection

GEMS was on site August 15 2019 to collect representative samples for both sediment and water

from Twickenham Pond Two (2) staff members were on site to facilitate the collection which

was done from safe locations along the banks of the pond A ponar dredge sampler spade

andor shovel was used to collect sediment samples as well as the standard collection of

water samples using laboratory provided sampling containers Standard quality assurance

and quality control practices were observed and standard chain of custody command

practices were used to submit samples to the laboratory All samples were submitted to an

accredited laboratory for analysis (Bureau Vertias)

Three (3) samples from Twickenham Pond were taken for sediment the following chemical

parameters were chosen and analyzed based on typical stormwater management pond sediment

buildup

bull Petroleum hydrocarbons (F2-F4) (PHCs) plus benzene toluene ethylbenzene and

xylenes (BTEX) metals and inorganics volatile organic compounds (VOCs) polycyclic

aromatic hydrocarbons (PAHs) and pH

In addition one (1) sediment sample from the pond was also analyzed for Toxicity Characteristic

Leaching Procedure (TCLP) for the purposes of off-site disposal as registered receivers require

the completion of this analysis prior to acceptance of any soil or sediment material

Three (3) surface water samples from the pond were taken the following parameters were analyzed

bull Surface Water Rapid Chemical Analysis Package (RCAp) Total Suspended Solids

(TSS) and Volatile Organic Compounds (VOC)s

All sample locations are shown on the figures provided in Appendix 1

Summary of Results

The following results were found within Twickenham Pond

Sediment samples were labelled TH1 TH2 and TH3 with the TCLP sample labelled TH (taken at the same location as the TH2 sediment sample)

The only reported exceedance for sediment in all three (3) sample locations was found in TH2 for F4 (C34-C50 Hydrocarbons)

The TCLP sample showed no toxic levels for any parameters within the sample Therefore the sample is considered non-hazardous

Water quality results from Twickenham Pond are also labelled as TH1 TH2 and TH3 Results were compared to both Ontario Regulation 153 and Provincial Water Quality Objectives (PWQO) exceedances were found when compared to both criteria

All sample exceedances and detections can be found in Tables 1 2 3 and 4 while the full summary of the lab results can be found in Appendix 2

While PWQO does not have a specific criteria for TSS the Canadian Council of Ministers of the Environment (CCME) recommend a maximum increase of 25mgL above background water quality for short-term exposure

Conclusions and Closure

The w ater quality was completed for the pu rposes of dewatering the po nd prior to any sediment

removal The Total Suspended Solids (TSS) levels within the pond were high which is an indicator

of poor water quality Sample locations TH2 (230 mgL) and TH3 (100 mgL) reported high TSS

levels while TH1 reported much higher levels at 730 mgL The results are likely skewed higher

as a result of the algae content in the water at the t ime of sampling As a result of the high TSS

filtration would be required should the pond need to be dewatered for future maintenance andor

clean out purposes It is also anticipated that the exceedances for the metals parameters are a

result of high TSS For dewatering purposes the water from the pond will need to be filtered prior

to entering the natural environment

Only F4 hydrocarbons were found at sediment sample location TH2 within Twickenham Pond

TH2 was found to exceed the Table 1 criteria limits but it meets the Table 3 criteria Only three

shoreline samples were able to be taken safely and feasibly this excludes the center of the pond

where more sediment accumulation could result in additional exceedances as such it cannot be

guaranteed that all other sediment within the pond meets either criteria Further sampling may

be required if the sediment is to be used on site or at a new location otherwise the sediment

should be disposed of at a registered landfill or receiving site capable of accepting Table 3

material It is expected that there will be exceedances above Table 1 criteria at other locations

within the pond due to the exceedance observed at sampling location TH2

Based on the results of the TCLP the tested parameters meet the Ontario Regulation 558 (as

amended) for non-hazardous material and do not need to be disposed of at a hazardous waste

disposal location While the material can be brought to a commercial site to be used (as the

sample did meet Table 3 criteria limits) it is not recommended as it could create structural

limitations due to the water content within the material Significant drying and mixing would be

required to reuse the material on a site capable of accepted Table 3 material As such GEMS

recommends bringing the removed material to a landfill for disposal

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Re Sediment and Water Sampling Memo ndash Twickenham Pond

Project No 20-202649

Introduction

Groundwater Environmental Management Services Inc (GEMS) has been retained by The

Municipal Infrastructure Group (TMIG) to collect and analyze representative water and sediment

samples taken from Twickenham Pond The project site is located within Twickenham Park east

of Bathurst Street just north of Canyon Hill Avenue in Richmond Hill Ontario

Field Sample Collection

GEMS was on site August 15 2019 to collect representative samples for both sediment and water

from Twickenham Pond Two (2) staff members were on site to facilitate the collection which

was done from safe locations along the banks of the pond A ponar dredge sampler spade

andor shovel was used to collect sediment samples as well as the standard collection of

water samples using laboratory provided sampling containers Standard quality assurance

and quality control practices were observed and standard chain of custody command

practices were used to submit samples to the laboratory All samples were submitted to an

accredited laboratory for analysis (Bureau Vertias)

Three (3) samples from Twickenham Pond were taken for sediment the following chemical

parameters were chosen and analyzed based on typical stormwater management pond sediment

buildup

bull Petroleum hydrocarbons (F2-F4) (PHCs) plus benzene toluene ethylbenzene and

xylenes (BTEX) metals and inorganics volatile organic compounds (VOCs) polycyclic

aromatic hydrocarbons (PAHs) and pH

Sediment and Water Sampling Memo August 30 2019

In addition one (1) sediment sample from the pond was also analyzed for Toxicity Characteristic

Leaching Procedure (TCLP) for the purposes of off-site disposal as registered receivers require

the completion of this analysis prior to acceptance of any soil or sediment material

Three (3) surface water samples from the pond were taken the following parameters were analyzed

bull Surface Water Rapid Chemical Analysis Package (RCAp) Total Suspended Solids

(TSS) and Volatile Organic Compounds (VOC)s

All sample locations are shown on the figures provided in Appendix 1

Summary of Results

The following results were found within Twickenham Pond

Sediment samples were labelled TH1 TH2 and TH3 with the TCLP sample labelled TH (taken at the same location as the TH2 sediment sample)

The only reported exceedance for sediment in all three (3) sample locations was found in TH2 for F4 (C34-C50 Hydrocarbons)

The TCLP sample showed no toxic levels for any parameters within the sample Therefore the sample is considered non-hazardous

Water quality results from Twickenham Pond are also labelled as TH1 TH2 and TH3 Results were compared to both Ontario Regulation 153 and Provincial Water Quality Objectives (PWQO) exceedances were found when compared to both criteria

All sample exceedances and detections can be found in Tables 1 2 3 and 4 while the full summary of the lab results can be found in Appendix 2

While PWQO does not have a specific criteria for TSS the Canadian Council of Ministers of the Environment (CCME) recommend a maximum increase of 25mgL above background water quality for short-term exposure

Conclusions and Closure

The w ater quality was completed for the pu rposes of dewatering the po nd prior to any sediment

removal The Total Suspended Solids (TSS) levels within the pond were high which is an indicator

of poor water quality Sample locations TH2 (230 mgL) and TH3 (100 mgL) reported high TSS

levels while TH1 reported much higher levels at 730 mgL The results are likely skewed higher

as a result of the algae content in the water at the t ime of sampling As a result of the high TSS

filtration would be required should the pond need to be dewatered for future maintenance andor

clean out purposes It is also anticipated that the exceedances for the metals parameters are a

result of high TSS For dewatering purposes the water from the pond will need to be filtered prior

to entering the natural environment

Only F4 hydrocarbons were found at sediment sample location TH2 within Twickenham Pond

TH2 was found to exceed the Table 1 criteria limits but it meets the Table 3 criteria Only three

shoreline samples were able to be taken safely and feasibly this excludes the center of the pond

where more sediment accumulation could result in additional exceedances as such it cannot be

guaranteed that all other sediment within the pond meets either criteria Further sampling may

be required if the sediment is to be used on site or at a new location otherwise the sediment

should be disposed of at a registered landfill or receiving site capable of accepting Table 3

material It is expected that there will be exceedances above Table 1 criteria at other locations

within the pond due to the exceedance observed at sampling location TH2

Sediment and Water Sampling Memo August 30 2019

Page 4

Based on the results of the TCLP the tested parameters meet the Ontario Regulation 558 (as

amended) for non-hazardous material and do not need to be disposed of at a hazardous waste

disposal location While the material can be brought to a commercial site to be used (as the

sample did meet Table 3 criteria limits) it is not recommended as it could create structural

limitations due to the water content within the material Significant drying and mixing would be

required to reuse the material on a site capable of accepted Table 3 material As such GEMS

recommends bringing the removed material to a landfill for disposal

This report was prepared by GEMS for TMIG as part of the Twickenham Pond Rehabilitation

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

In addition one (1) sediment sample from the pond was also analyzed for Toxicity Characteristic

Leaching Procedure (TCLP) for the purposes of off-site disposal as registered receivers require

the completion of this analysis prior to acceptance of any soil or sediment material

Three (3) surface water samples from the pond were taken the following parameters were analyzed

bull Surface Water Rapid Chemical Analysis Package (RCAp) Total Suspended Solids

(TSS) and Volatile Organic Compounds (VOC)s

All sample locations are shown on the figures provided in Appendix 1

Summary of Results

The following results were found within Twickenham Pond

Sediment samples were labelled TH1 TH2 and TH3 with the TCLP sample labelled TH (taken at the same location as the TH2 sediment sample)

The only reported exceedance for sediment in all three (3) sample locations was found in TH2 for F4 (C34-C50 Hydrocarbons)

The TCLP sample showed no toxic levels for any parameters within the sample Therefore the sample is considered non-hazardous

Water quality results from Twickenham Pond are also labelled as TH1 TH2 and TH3 Results were compared to both Ontario Regulation 153 and Provincial Water Quality Objectives (PWQO) exceedances were found when compared to both criteria

All sample exceedances and detections can be found in Tables 1 2 3 and 4 while the full summary of the lab results can be found in Appendix 2

While PWQO does not have a specific criteria for TSS the Canadian Council of Ministers of the Environment (CCME) recommend a maximum increase of 25mgL above background water quality for short-term exposure

Conclusions and Closure

The w ater quality was completed for the pu rposes of dewatering the po nd prior to any sediment

removal The Total Suspended Solids (TSS) levels within the pond were high which is an indicator

of poor water quality Sample locations TH2 (230 mgL) and TH3 (100 mgL) reported high TSS

levels while TH1 reported much higher levels at 730 mgL The results are likely skewed higher

as a result of the algae content in the water at the t ime of sampling As a result of the high TSS

filtration would be required should the pond need to be dewatered for future maintenance andor

clean out purposes It is also anticipated that the exceedances for the metals parameters are a

result of high TSS For dewatering purposes the water from the pond will need to be filtered prior

to entering the natural environment

Only F4 hydrocarbons were found at sediment sample location TH2 within Twickenham Pond

TH2 was found to exceed the Table 1 criteria limits but it meets the Table 3 criteria Only three

shoreline samples were able to be taken safely and feasibly this excludes the center of the pond

where more sediment accumulation could result in additional exceedances as such it cannot be

guaranteed that all other sediment within the pond meets either criteria Further sampling may

be required if the sediment is to be used on site or at a new location otherwise the sediment

should be disposed of at a registered landfill or receiving site capable of accepting Table 3

material It is expected that there will be exceedances above Table 1 criteria at other locations

within the pond due to the exceedance observed at sampling location TH2

Based on the results of the TCLP the tested parameters meet the Ontario Regulation 558 (as

amended) for non-hazardous material and do not need to be disposed of at a hazardous waste

disposal location While the material can be brought to a commercial site to be used (as the

sample did meet Table 3 criteria limits) it is not recommended as it could create structural

limitations due to the water content within the material Significant drying and mixing would be

required to reuse the material on a site capable of accepted Table 3 material As such GEMS

recommends bringing the removed material to a landfill for disposal

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

While PWQO does not have a specific criteria for TSS the Canadian Council of Ministers of the Environment (CCME) recommend a maximum increase of 25mgL above background water quality for short-term exposure

Conclusions and Closure

The w ater quality was completed for the pu rposes of dewatering the po nd prior to any sediment

removal The Total Suspended Solids (TSS) levels within the pond were high which is an indicator

of poor water quality Sample locations TH2 (230 mgL) and TH3 (100 mgL) reported high TSS

levels while TH1 reported much higher levels at 730 mgL The results are likely skewed higher

as a result of the algae content in the water at the t ime of sampling As a result of the high TSS

filtration would be required should the pond need to be dewatered for future maintenance andor

clean out purposes It is also anticipated that the exceedances for the metals parameters are a

result of high TSS For dewatering purposes the water from the pond will need to be filtered prior

to entering the natural environment

Only F4 hydrocarbons were found at sediment sample location TH2 within Twickenham Pond

TH2 was found to exceed the Table 1 criteria limits but it meets the Table 3 criteria Only three

shoreline samples were able to be taken safely and feasibly this excludes the center of the pond

where more sediment accumulation could result in additional exceedances as such it cannot be

guaranteed that all other sediment within the pond meets either criteria Further sampling may

be required if the sediment is to be used on site or at a new location otherwise the sediment

should be disposed of at a registered landfill or receiving site capable of accepting Table 3

material It is expected that there will be exceedances above Table 1 criteria at other locations

within the pond due to the exceedance observed at sampling location TH2

Based on the results of the TCLP the tested parameters meet the Ontario Regulation 558 (as

amended) for non-hazardous material and do not need to be disposed of at a hazardous waste

disposal location While the material can be brought to a commercial site to be used (as the

sample did meet Table 3 criteria limits) it is not recommended as it could create structural

limitations due to the water content within the material Significant drying and mixing would be

required to reuse the material on a site capable of accepted Table 3 material As such GEMS

recommends bringing the removed material to a landfill for disposal

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Page 4

Based on the results of the TCLP the tested parameters meet the Ontario Regulation 558 (as

amended) for non-hazardous material and do not need to be disposed of at a hazardous waste

disposal location While the material can be brought to a commercial site to be used (as the

sample did meet Table 3 criteria limits) it is not recommended as it could create structural

limitations due to the water content within the material Significant drying and mixing would be

required to reuse the material on a site capable of accepted Table 3 material As such GEMS

recommends bringing the removed material to a landfill for disposal

This report was prepared by GEMS for TMIG as part of the Twickenham Pond Rehabilitation

Schedule B Municipal Class Environmental Assessment The report provides a summary of the

sediment and surface water conditions in Twickenham Pond Conclusions are based solely on

the collected and available information Any use by which a third party makes of this report or

any reliance on or decisions to be made based on it are the sole responsibility of such third

parties

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

Leachate Blank A blank matrix containing all reagents used in the leaching procedure Used to determine any process contamination

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

(1) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

(2) The matrix spike recovery was below the lower control limit This may be due in part to the reducing environment of the sample The matrix spike was reanalyzed to confirm result

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)

NA = Not Applicable

Duplicate Paired analysis of a separate portion of the same sample Used to evaluate the variance in the measurement

Matrix Spike A sample to which a known amount of the analyte of interest has been added Used to evaluate sample matrix interference

QC Standard A sample of known concentration prepared by an external agency under stringent conditions Used as an independent check of method accuracy

Spiked Blank A blank matrix sample to which a known amount of the analyte usually from a second source has been added Used to evaluate method accuracy

Method Blank A blank matrix containing all reagents used in the analytical procedure Used to identify laboratory contamination

Surrogate A pure or isotopically labeled compound whose behavior mirrors the analytes of interest Used to evaluate extraction efficiency

NC (Matrix Spike) The recovery in the matrix spike was not calculated The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration)

NC (Duplicate RPD) The duplicate RPD was not calculated The concentration in the sample andor duplicate was too low to permit a reliable RPD calculation (absolute difference lt= 2x RDL)
