1.0 Introduction

Since the results of contaminant analysis are to be compared to site condition standards in the Soil, Ground Water and Sediment Standards, it is essential that well documented,validated and consistently applied analytical methods be utilized and that appropriate quality assurance and quality control procedures be carried out.

Analytical methods and QC protocols set out in this document, are based on recognized standard setting organizations {e.g. the Ontario Ministry of the Environment (MOE), United States Environmental Protection Agency, (USEPA), and American Society for Testing and Materials, (ASTM)}. If alternate MOE approved methods are used, these must meet Reporting Detection Limits, (RDL’s), as detailed in section 9.0 of this document, which is headed, Sampling and Analysis Summary Information, and must meet performance criteria, as stated.
The information presented in this document must be utilized to ensure that the data resulting from laboratory analyses are of sufficient quality upon which to base decisions required to complete a Record of Site Condition (RSC).

2.0 Laboratory Quality Management

The quality of data, resulting from laboratory analyses, depends upon planning, documentation and adherence to, policies and procedures, for sampling, sample transportation, sample storage, analysis and reporting. There are potential errors associated with each step. The role of quality management is to identify, measure and minimize these errors. Laboratories must have available evidence that the standard of the analysis provided ensures that the data quality will meet the requirements of this Regulation and Ministry Standards.

It is recommended that, in addition, the laboratory adopt a program such as the Quality Management Protocol set out in the Ontario Ministry of the Environment Publication "Protocol for the Sampling and Analysis of Industrial/Municipal Wastewater," (MOEE, 1994a). This document describes protocols for sampling and analysis of wastewater. However, the concepts/principles set out in the Protocol document can be applied to media that are addressed in the Soil, Ground Water and Sediment Standards.

All laboratories participating in the analysis of contaminants addressed in the Soil, Ground Water and Sediment Standards, Ministry policies r requirements must follow the analytical procedures set out in section 47 of the Regulation.

3.0 Quality Control and Quality Assurance

Based on a good Quality Management System, Laboratories must develop and document where applicable:

1. analytical recovery data, such as average recovery, range, and relative standard deviation for each parameter analyzed;
2. data related to method performance, such as control limits for calibration standards, standardization, duplicates, surrogate recovery, and recovery of all the parameters in a group/scan;

The following tables are examples of some of the data that should be documented:

Example 1

Contaminant	Recovery Range CRM (%)	Average Recovery CRM (%)	Surrogate Recovery (%)	Between Run Precision (% RSD)
Naphthalene	66 – 81	73	25 – 150	20
Phenanthrene	82 – 90	86	25 –- 150	4.3

Example 2

Contaminant	Calibration (# of points)	Linearity Limit (mg/L)	Control Standard Check Level (mg/L)	Control Standard Check Precision (%RSD)	Method Blank Range (mg/L)
Chromium	4 point	10	2.191	2	-0.06
Lead	5 point	20	13.277	2.5	-0.25

Calculation of Precision and Accuracy Estimates:

Accuracy/Trueness, (bias): Analyze reagent blank and reference material using candidate method, ( 10 repeats ); subtract mean reagent blank value from mean analyte value for reference material; compare with true or accepted true values for reference material, t-test.

Precision: analyze standards and reference materials, or fortified sample blanks or duplicate samples at various concentrations across working range, (10 repeats); determine standard deviation or the standard deviation of the difference of duplicates at each concentration.

The following are recommended Quality Procedures that should be included as part of a laboratory’s methodology:

A detailed sample pre-treatment/preparation, clean-up (if required), instrumental measurement method, and data reporting procedure.

3.1 Pre-service QC must include the following where applicable;

• labware and reagent blanks;
• instrument set-up standard;
• reference standard to validate in-house standards;
• certified reference material to validate method recovery, or spiked matrix if no CRM is available;
• instrument detection limits (IDLs) and detector linearity curves (minimum of 3 point calibration);

3.2 In-service QC must include the following where applicable:

• baseline drift blanks;
• standards;
• instrument checks;

3.3 Run quality QC and QA must include the following where applicable:

• method blanks;
• in-house matrix check material;
• duplicates (minimum of one set per run of 30 samples);
• For the purpose of this protocol, a duplicate sample is defined as a second aliquot from the same sample container;
• surrogates (added prior to organic extraction);
• The surrogates should be selected to cover the whole range of the particular scan. It is recommended to use a minimum of three surrogates per organic type scan;
• spiked samples

4.0 Protocol for Accepting Analytical Results

In determining the acceptability of laboratory data, owners and qualified persons should have regard to the following considerations:

• the method performance criteria as outlined in Section 9.0 have been met or exceeded;
• the results of all laboratory QC samples that are applicable to the matrix and contaminant groups of interest (method blank, duplicate, spiked blank, spiked sample) are within the statistically determined control limits.
• the laboratory analyst is expected to respond to any QC results which exceed the control limits.
• recoveries of all surrogates (organic analyses) where applicable are acceptable;

5.0 Reporting of Data

Each laboratory performing data analysis must have available on request precision, uncertainty and accuracy estimates associated with the reported results.

Accuracy estimates can be determined through periodic analysis of standard or certified reference materials as available for each contaminant group selected at appropriate concentrations.

The analytical data is to be reported without correction, unless correction is clearly identified and described. Soil and Sediment data are to be reported on a dry weight basis.

Where samples have been analyzed “as is” ( without any treatment, e.g. drying, of the sample prior to analysis ),the moisture content must be calculated and applied to the result. This should be noted in the report.

Data that does not meet the available Performance Criteria outlined in Appendix A for each analytical test group should be reported only if there is insufficient sample for repeat analysis and justification can be given for inability to meet these criteria.

Where a maximum of 10 % of the components of a scan exceeds control limits, ( excluding zero percent recoveries ), the scan can still be considered as valid providing these are flagged and justification provided.

6.0 Criteria for Reporting of Data

6.1 Reporting Detection Limits (RDLs) for Soil and Sediment

Reporting Detection Limits have been set at 1/10 of the maximum permissible standard for the contaminants set out in the Soil, Ground Water, and Sediment Standard or the Ministry Laboratory Method Detection Limit, (MDL), (as calculated in 7.0 and 8.0) whichever is higher.
For certain parameters, noted in Appendix B, the RDL ( based on the MDL listed in the reference method ) value is higher than the Standard value. Where the RDL is higher than the Standard, analytical laboratories are required to use more sensitive techniques to achieve an RDL that is lower than the Standard value.

Where no RDL value is provided laboratories are expected to achieve an MDL value less than the Standard provided.

6.2 Reporting Detection Limits (RDLs) for Potable Water

The following criteria for the reporting of RDL’s have been derived from the Drinking Water Protection Regulation and must be applied to the analysis of Potable Water.

1. Laboratories must achieve Method Detection Limits (MDL’s) less than or equal to the RDL values.
2. Laboratories that achieve MDL’s less than RDL’s must report results below RDL values.
3. Reporting units will be in µg/L except for dioxins/furans reporting units, which will be in (pg/L), and some inorganic parameters which will be in mg/L.
4. Achieving RDL values, as outlined in Appendix B, requires the following:
   • the capability and appropriate use of modern technology;
   • good laboratory practices (GLP);
   • statistically sound detection limit calculations as outlined in Sections 7 and 8 of this document;

Basis of given RDL values:

1. RDL values for a number of contaminants are set at a percentage between 10% and 50% of the Drinking Water Standards, or the MDL of the MOE-LSB method.
2. For certain contaminants the RDL has been determined by the Standard value due to an effects based number being below the RDL.
3. Contaminants which are not health-related have RDL values set at 50% of the Drinking Water Standards (based on non-health related criteria such as aesthetics).
4. Where no RDL has been specified the laboratory must report the analytical result and where applicable, the appropriate detection limit qualifier e.g. <MDL.

Data must be reported below the RDL value according to individual laboratory MDL’s and where applicable, with the appropriate detection limit qualifier e.g. <MDL.

Where no RDL value is provided laboratories are expected to achieve an MDL value less than the Standard provided.

The following table shows how examples of volatile organic contaminants would be reported the laboratory for a single sample analysis:

Volatile Organic Compounds Results: Sample No. 1

Contaminant	Units	Result	Value Qualifier	RDL
Benzene	µg/L	0.2		0.5
Carbon tetrachloride	µg/L	0.2	<MDL	0.5
Trichloroethylene	µg/L	6		5
Xylene (total)	µg/L	20		150

7.0 Procedure for MDL Determination

Take a minimum of eight aliquots of the sample to be used to calculate the method detection limit and process each through the entire analytical method.

If a blank measurement is required to calculate the measured level of Contaminant, obtain a separate blank measurement for each sample aliquot analyzed.

Calculate a result (x) for each sample/blank pair.

Calculate the standard deviation (S) of the replicate measurements as follows:

where:

x_i = the analytical results in the final method reporting units for the eight replicate aliquots (i = 1 to 8)
x^- = the average of the eight replicate measurements

An alternative is to use previously determined within run replicate analysis data and calculate the standard deviation (S) of the replicate measurements as follows. This is suggested for Soil samples.

Compute the MDL as follows: MDL = t( n-1, a= 0.01 ) S

where:

t( n-1, a = 0.01 ) is the Student's value appropriate for a 99% confidence level given the degrees of freedom n-1.
S = the standard deviation as determined above.

				36.15 (Sum of squares)

Drinking Water MDL = 6.01 (SQRT – sum of squares)

The MDL is calculated by the same procedure used to calculate the MISA DL and regulatory limit.

The MDL for each of the 17 “toxic congeners” is determined from 8 spiked samples. The standard deviation of the mean is multiplied by student t value (3 if 8 samples are analyzed).

The MDL for each of the 17 congeners is multiplied by its toxic equivalent factor (TEF) to convert its value to equivalents of 2,3,7,8-TCDD.

These values are then squared and summed. The square root of the sum of squares is the MDL value for the 2,3,7,8-TCDD Toxic Equivalent Quantity (TEQ)

^a I-TEF - International Toxic Equivalent Factor
^b MDL- Method Detection Limit for each individual congener

ANALYSIS:

Method Principle: This analytical method is used to determine the concentrations of PCDDs, PCDFs and DLPCBs in a variety of matrices using isotope dilution with mass spectrometric detection. The different analytical processing techniques for each matrix type are briefly described below. All samples are fortified prior to sample extraction, digestion or elution with known amounts of [13C12 -] isotopically labeled PCDDs/PCDFs and/or DLPCBs.
All PCDDs/PCDFs and DLPCBs are quantified against these labeled standards. Sample extracts are cleaned using a 2-stage (silica/alumina) when PCDDs/PCDFs only are requested or no interferences such as polychlorinated diphenyl ethers(PCDPEs) are expected in the sample. If PCDDs/PCDFs and DLPCBs are requested or if a sample is highly contaminated with bulk interferences, a carbon cleanup procedure must be incorporated (3-stage).
Sample Preparation:
Recommended: Samples are air dried, ground, and homogenized. Contaminants are extracted using Soxhlet extraction with Toluene, cleaned, and analyzed by Mass Spectrometry. A 3-stage chromatographic clean-up procedure is used to remove any potential chemical interferences.
Alternate: Carbon clean-up not done; For DF and DLPCB requests, sample extract may be split;
Instrumental Analysis:
Recommended: GC/high resolution MS, with confirmation by GC-MS/MS.
Alternate: Equivalent to U.S. EPA 1613, Environment Canada 1/RM/19 and CEN-EN 1948 for PCDD/PCDFs;
EPA8290, 1613, EPS1/RM/19, EPS1/RM/23;
Laboratory QC Samples: Fortify each sample with solution of 15,13 C12 -isotopically labeled PCDD and PCDF congeners and a solution of 12, 13 C12-isotopically labeled DLPCB congeners

ANALYTICAL TEST GROUP: Petroleum Hydrocarbons

Matrix: Soil, Sediment
Parameters: Fractions: F1 (C6 to C10 ), F2 (C10 to C16), F3 (C16 to C34), F4 (C34 to C50), F4g (gravimetric)

SAMPLING:

Container: Clear or amber glass jar, with airtight cap and wide-mouth opening. Caps -Teflon or aluminum-faced, with Teflon-faced liners.
Sample Volume: 50 g minimum
Field QC Samples:
Preservation: No preservatives added.
Sample Storage: To avoid losses in the C6 to C10 fraction, the methanol extraction of the samples should be done within 48 hours of sample receipt or a maximum of 7 days from sample collection. For the C10 to C50 fractions, again holding times should be minimized. It is recommended that samples should be extracted no later than 14 days of sample receipt and extracts held no more than 7 days.
Precautions/Notes: It is not intended that the results of the PHC analysis include either BTEX or PAHs. If the concentration of BTEX or PAHs are of a concentration to significantly change the PHC value, then these values must be determined and subtracted from the PHC value.

ANALYSIS:

The analysis of PHCs must be in accordance to the Canadian Council of Ministers of the Environment (CCME) method “Reference Method for the Canada-wide Standard for Petroleum Hydrocarbons (CWS-PHC) in Soil – Tier 1 Method”. This method is composed of both “prescriptive” and “performance” based elements. All prescriptive elements must be followed and it is suggested that all performance-based elements also be followed, as per the method, until suitable reference material is available, to fairly evaluate equivalence of an alternate method. A procedure to evaluate the suitability of alternate methods is available from the MOE. As well a draft procedure is available from Alberta Environment, “Alberta Environment Draft Addenda to the PHC-CWS, Appendix 6, Validation of Alternate Methods”.
Method Principle: Fraction F1 is determined by extracting a 5 g soil sample with methanol then analyzing by gas chromatography with a flame ionization detector.
Fractions F2, F3, F4 are determined by extracting a 5 g soil sample with 50:50 hexane:acetone then analyzing by gas chromatography with a flame ionization detector.
Sample Preparation:
Recommended: For F1, 5 g or greater soil sample is extracted with methanol. The methanol is separated from the soil. The methanol is added to a purging vessel and analyzed.
For F2, F3, F4, 5 g or greater soil sample is extracted with 50:50 hexane:acetone in a Soxhlet apparatus or equivalent. The solvent recovered from the extracted sample is dried using sodium sulphate and treated either in situ or by column chromatography with silica gel to remove polar material, (50:50 dichloromethane:hexane), and analyzed.
Instrumental Analysis:
Recommended: For F1 the sample is analyzed by gas chromatography with a 100% poly(dimethylsiloxane) (DB-1 or equivalent) column and a flame ionization detector. All area counts are integrated from the beginning of the nC6 peak to the apex of the nC10 peak to give F1. Standards containing nC6, nC10 and toluene are run. Toluene is used as a calibration standard. The nC6 and nC10 response factors must be within 30% of the response factor for toluene.
For F2, F3, F4 The sample is analyzed by gas chromatography with a 100% poly(dimethylsiloxane) column and a flame ionization detector in the following three ranges.

• F2 result, C10 to C16 hydrocarbons, is determined by integration of all area counts from the apex of the nC10 peak to the apex of the nC16 peak. The average response factor for nC10, nC16 and nC34 hydrocarbons is used for primary calibration.
• F3 result, C16 to C34 hydrocarbons, is determined by integration of all area counts from the apex of the nC16 peak to the apex of the nC34 peak. The average response factor for nC10, nC16 and nC34 hydrocarbons is used for primary calibration.
• F4 result, C34 to C50 hydrocarbons, is determined by integration of all area counts from the apex of the nC34 peak to the apex of the nC50 peak. The average response factor for nC10, nC16 and nC34 hydrocarbons is used for primary calibration. The GC response factor of the nC50 must be within 30% of the average response factor of the nC10, nC16 and nC34 hydrocarbons. This result gives fraction F4 provided that the chromatogram descends to baseline by the retention time of nC50.
• F4g result, gravimetric analysis, must be determined if the baseline is not returned in F4 at or before C50. A 5 g or greater soil sample is extracted with 50:50 hexane:acetone. The solvent is evaporated and the weight of residue determined. If the result is less than 50% of the criteria for the soil type and proposed use, stop the analysis and report this result. If the result is higher than 50% of the criteria, the sample can then be reconstituted in 50:50 dichloromethane:hexane, treated with silica gel one time only, re-evaporated and the weight of residue determined. Both the F4 (GC) result and the F4g (gravimetric) result are reported but the greater result is reported as Fraction F4.

ANALYSIS:

Method Principle: This analytical method is used to determine the concentrations of PCDDs, PCDFs and DLPCBs in a variety of matrices using isotope dilution with mass spectrometric detection. The different analytical processing techniques for each matrix type are briefly described below.

All samples are fortified prior to sample extraction, digestion or elution with known amounts of [13C12 -] isotopically labeled PCDDs/PCDFs and/or DLPCBs. All PCDDs/PCDFs and DLPCBs are quantified against these labeled standards. Sample extracts are cleaned using a 2-stage (silica/alumina) when PCDDs/PCDFs only are requested or no interferences such as polychlorinated diphenyl ethers(PCDPEs) are expected in the sample. If PCDDs/PCDFs and DLPCBs are requested or if a sample is highly contaminated with bulk interferences, a carbon cleanup procedure must be incorporated (3-stage). The instrument detection is common to the analysis of all matrices.

Sample Preparation:
Recommended: Samples are liquid/liquid extracted with Pentane, followed by a 2-stage chromatographic clean-up procedure to remove potential chemical interferences. Final extracts are analyzed by Gas Chromatography-High Resolution Mass Spectrometry, (GC-HRMS).
Samples containing particulates are extracted using C 18 Solid Phase adsorption disk. Toluene/Ethanol is used to extract PCDDs / PCDFs and DLPCBs from the disk and particulates. This is followed by a 2-stage chromatographic clean-up.

Alternate: Extract with Methylene Chloride;
Extract samples with particulates using filter and Soxhlet in Methanol and DCM 16 hours;

Instrumental Analysis:
Recommended: GC/High Resolution MS, with confirmation by GC-Tandem MS if necessary.

Alternate: Equivalent to U.S. EPA 1613, Environment Canada 1/RM/19 and CEN-EN 1948 for PCDD/PCDFs.
Laboratory QC Samples: Fortify each sample with solution of 15,13 C12 -isotopically labeled PCDD and PCDF congeners and a solution of 12, 13 C12-isotopically labeled DLPCB congeners

Sample Storage: To avoid losses in the C6 to C10 fraction, the samples should be analysed within 48 hours of sample receipt or a maximum of 7 days from sample collection. For the C10 to C50 fractions, again holding times should be minimized,. It is recommended samples should be extracted no later than 14 days of sample receipt and extracts held no more than 7 days.
Precautions/Notes: It is not intended that the results of the PHC analysis include either BTEX or PAHs. If the concentration of BTEX or PAHs are of a concentration to significantly change the PHC value, then these values must be determined and subtracted from the PHC value.

ANALYSIS:

Although a national method is not available for water samples, analysis of PHCs should be in accordance to applicable sections of the Canadian Council of Ministers of the Environment (CCME) method “Reference Method for the Canada-wide Standard for Petroleum Hydrocarbons (CWS-PHC) in Soil – Tier 1 Method”. Extraction should involve a series of two liquid/liquid extractions of an 800mL sample with 50mL of hexane. The CWS-PHC method is composed of both “prescriptive” and “performance” based elements. All applicable prescriptive elements must be followed and criteria for all performance elements satisfied.
Method Principle: Fraction F1 is determined by purging a volume of a water sample, then analyzing by gas chromatography with a flame ionization detector.
Fractions F2, F3 and F4 are determined by extracting an 800 mL sample twice with 50mL of hexane by liquid/liquid extraction (e.g. tumble), then analyzing by gas chromatography with a flame ionization detector.
Sample Preparation:
Recommended: For F1, a volume of water sample is purged before analysis.
For F2, F3, F4, an 800 mL sample is extracted twice with 50mL of hexane by liquid/liquid extraction (e.g. tumble). The solvent recovered from the extracted sample is dried using sodium sulphate and treated either in situ or by column chromatography with silica gel to remove polar material (50:50 dichloromethane:hexane).
Instrumental Analysis:
Recommended: For F1,the sample is analyzed by gas chromatography with a 100% poly(dimethylsiloxane) (DB-1 or equivalent) column and a flame ionization detector. All area counts are integrated from the beginning of the nC6 peak to the apex of the nC10 peak to give F1. Standards containing nC6, nC10 and toluene are run. Toluene is used as a calibration standard. The nC6 and nC10 response factors must be within 30% of the response factor for toluene
For F2, F3, F4 the sample is analyzed by gas chromatography with a 100% poly(dimethylsiloxane) column and a flame ionization detector in the following three ranges.

• F2 result, C10 to C16 hydrocarbons, is determined by integration of all area counts from the apex of the nC10 peak to the apex of the nC16 peak. The average response factor for nC10, nC16 and nC34 hydrocarbons is used for primary calibration.
• F3 result, C16 to C34 hydrocarbons, is determined by integration of all area counts from the apex of the nC16 peak to the apex of the nC34 peak. The average response factor for nC10, nC16 and nC34 hydrocarbons is used for primary calibration
• F4 result, C34 to C50 hydrocarbons, is determined by integration of all area counts from the apex of the nC34 peak to the apex of the nC50 peak. The average response factor for nC10, nC16 and nC34 hydrocarbons is used for primary calibration. The GC response factor of the nC50 must be within 30% of the average response factor of the nC10, nC16 and nC34 hydrocarbons. This result gives fraction F4 provided that the chromatogram descends to baseline by the retention time of nC50.
• F4g result, gravimetric analysis, must be determined if the baseline is not returned in F4 at or before C50. An 800mL sample is extracted twice with 50mL hexane. The solvent is evaporated and the weight of residue determined. If the result is less than 50% of the criteria for the proposed use, stop the analysis and report this result. If the result is higher than 50% of the criteria, the sample can then be reconstituted in 50:50 dichloromethane:hexane, treated with silica gel one time only, re-evaporated and the weight of residue determined. Both the F4 (GC) result and the F4g (gravimetric) result are reported but the greater result is reported as Fraction F4.
