1.0 INTRODUCTION This report provides a summary and interpretation of the Muggah Creek Remediation Project Ambient Air Monitoring Program results for the month of February 2003. In the fall of 2001, an expanded ambient air monitoring program (AAMP) was developed and implemented for the Sydney Muggah Creek Remediation Project. The AAMP was designed to monitor air quality within the Sydney airshed both prior to (background) and during the proposed remedial activities to be performed on the Sydney Tar Ponds and Coke Ovens site. The monitoring is being performed to determine whether there are any long-term and/or short-term effects on air quality from the proposed remedial activities, and also to assess impacts to the airshed from the Sydney Tar Ponds and Coke Ovens site during periods of inactivity. The program consists of sampling ambient air for total suspended particulate (TSP - 3 fixed locations), particulate matter less than 10 microns in diameter (PM10 - 3 fixed locations), metal parameters (4 fixed locations), as well as polyaromatic hydrocarbon (PAH) parameters and volatile organic compound (VOC) parameters at 6 fixed locations throughout Sydney. In addition, a mobile station is available to be used at various locations, depending on the location of remedial activities. Particulate matter less than 2.5 microns in diameter (PM2.5) was previously analyzed between the months of November 2001 and July 2002 on samples collected at 3 fixed locations, along with metals from the PM2.5 fraction. PM2.5 analysis was temporarily dropped from the AAMP because the laboratory detection limits were considered too high and did not meet the detection limit specified in the method for the analysis of PM2.5. AMEC has sourced a laboratory with equipment that can achieve the applied method detection limit. As a result, the PM2.5 analysis at 3 fixed locations was reinstated in December 2002 to the program’s sampling/analytical scope. Only a few metals were being detected from the PM2.5 and, as a result, the metals analysis was permanently dropped from the AAMP. This report summarizes air monitoring results for two sampling events, performed on February 8th and 20th.

Refer to Figure 1 for the sampling locations. The sampling frequency for the program follows a 6-day National Air Pollution Surveillance (NAPS) schedule during periods when activity is occurring at the Tar Ponds and/or Coke Ovens site. The sampling during periods of non-activity is performed on a 12-day schedule falling on NAPS days. The sampling duration for each event is 24-hours (midnight to midnight). Sampling falling on NAPS days was performed on February 8th and 20th. Weather information for the program during the month of February was obtained from the two project weather stations, one located at the former Public Information Display Centre (PIDC) site, off of Terminal Road, and the other at the southeast end of the Coke Ovens site. Additional meteorological data (humidity, precipitation, barometric pressure and fog) was acquired from the Environment Canada weather station located at the Sydney Airport.

2.1 SUMMARY OF METHODS AND EQUIPMENT The field program consisted of sampling for PM2.5 using low volume sampling equipment, PM10, PAHs, TSP and metals, using high volume sampling equipment, and VOCs using stainless steel evacuated canisters. The following provides a summary of methods for sampling, parameters analyzed and equipment employed. Refer to Appendix “A” for a sketch of the equipment and a description of sampling procedures. 2.1.1 PM2.5 Sampling for PM2.5 was conducted in accordance with the United States Environmental Protection Agency (USEPA) Reference Method for the Determination of Fine Particulate Matter as PM2.5 in the Atmosphere (40 CFR, Subchapter C, Part 50, Appendix L). Sampling was performed with the BGI PQ-200 PM2.5 sampling system. The media used to capture PM2.5 were 47 mm polytetrafluoroethylene (PTFE) teflon filters. Analysis was performed at Chester LabNet in Tigard, Oregon, USA. 2.1.2 TSP and Metals The sampling protocol for TSP was in accordance with the Environment Canada Method for the Measurement of Suspended Particulate in the Atmosphere (Environment Canada, 1973). All sampling was performed with Tisch High Volume samplers. Calibration of each sampler was completed using orifice resistance plates and a water manometer. Initial and final flow checks were performed on each instrument for the 24-hour sampling period. The media used to capture TSP and metals were quartz filters. Analyses were performed at the Environmental Services Laboratory (ESL) in Sydney. Refer to Table 2 for a list of metals parameters analyzed from the TSP fraction.

Aluminum Boron Calcium Lithium Silver Uranium Magnesium Selenium Antimony Cadmium Copper Manganese Sodium Vanadium Potassium Mercury (1) Barium Chromium Iron Molybdenum Thallium Zinc Sulfur Beryllium Cobalt Lead Nickel Tin Strontium Arsenic

Note: (1) Mercury is analyzed as only the particulate fraction.

2.1.3 PM10 and Metals Sampling for PM10 was performed in accordance with the USEPA Reference Method for the Determination of Particulate Matter as PM10 in the Atmosphere (40 CFR, Part 50, Appendix M). All sampling was performed with either Graesby Anderson or Tisch High Volume samplers. Initial and final flow checks were performed during the 24-hour sampling period. The media used to capture PM10 and metals were quartz filters. ESL performed the analyses. Refer to Table 2 for a list of metals parameters analyzed from the PM10 fraction. 2.1.4 PAHs PAH compounds were sampled in accordance with the USEPA TO13A Method. All sampling was performed with either Graesby Anderson or Tisch High Volume samplers. Initial and final flow checks were performed on each sampler during the 24-hour sampling period. The media used to capture PAH compounds were glass-fibre filters with a polyurethane foam (PUF)

2.1.5 VOCs Sampling for VOCs was performed in accordance with the USEPA TO14A Method. An evacuated stainless steel canister was used to collect a sub-atmospheric (pressure) sample. A flow restrictive device (cantroller) was employed to acquire the samples over a 24-hour period. The evacuated canisters were transported to the Philip Service Corporation (PSC) analytical laboratory in Burlington, Ontario for analyses. Refer to Table 4 for the list of VOCs analyzed.

All QA/QC sample analyses was performed at PSC. The February 20th QA/QC sampling consisted of obtaining duplicate samples for PAHs at the Frederick Street location, PM10 and metals at the Victoria Road location and VOCs at the Intercolonial Street location. The duplicate sample set for VOCs was forwarded to Environment Canada’s laboratory for analysis after PSC analyzed the samples. 2.3 FIELD OBSERVATIONS The monitoring program was performed from midnight to midnight on February 8th and 20th. Table 5 provides a summary of field observations for each sampling day.

2.4 WEATHER PARAMETER MEASUREMENTS Weather information for the wind speed, wind direction and temperature parameters were obtained from the project weather station located at the former PIDC site and from the project weather station situated at the Coke Ovens site. The PIDC project weather station is located south of the South Tar Pond, off of Terminal Road, and is approximately 900 metres from the southwest corner of the Coke Ovens site (Figure 1). The Coke Ovens project weather station is situated at the southeast perimeter of the Coke Ovens site approximately 625 metres to the east of the Victoria Road sampling location (Figure 1). Relative humidity, precipitation, barometric pressure, fog and snow cover were obtained from the Sydney Airport Environment Canada weather station. All measurements were recorded on an hourly basis. Table 6 provides a summary of weather measurements for each 24-hour sampling day for February 2003.

Figures 2 to 5 provide graphical presentations of wind direction and speed in the form of wind roses inset on a plan view of the sampling locations for each sampling day. The wind roses provide information on wind frequency, direction and speed for each sampling day. The length of each bar for a direction indicates the percent of time the wind blows from that direction. The wind direction is defined as that from which the wind is blowing (i.e., a north wind comes from the north). Each hatch pattern within the wind rose bars represents the percentage of time for a velocity. A legend is included on each wind rose for interpretation. Winds were predominately from the ENE/W/WNW/NW directions on February 8th and S/SSW on February 20th at the PIDC project weather station. Winds were prevailing from the WSW on February 8th and SSW on February 20th at the Coke Ovens project weather station. The winds at the PIDC project weather station location were strongest on February 8th with an average wind speed of 20.0 km/hr and weakest on February 20th with an average wind speed of 15.8 km/hr. The winds at the Coke Ovens project weather station location were strongest on February 8th with an average wind speed of 36.7 km/hr and weakest on February 20th with an average wind speed of 29.1 km/hr. We note that the wind speed readings at the Coke Ovens project weather station were higher by approximately 84% than the wind speed readings at the PIDC project weather station. Comparisons with wind speeds at the Sydney Airport Environment Canada weather station were made for the month of November 2002. The Airport data is more comparable to the PIDC weather data than to the Coke Ovens project weather data. Environment Canada is currently examining the equipment at the PIDC and Coke Ovens project weather stations to determine whether the variances are equipment related or not.

3.0 PROGRAM RESULTS The following section provides a summary of PM10, TSP, metals, PM2.5, PAH and VOC results for the month of February. The tables in this section summarize only those values that were detected. Refer to Appendix “B” for a complete set of results contained in the Data Validation Report. A review of available Nova Scotia standards and guidelines indicate that Nova Scotia only provides an ambient air quality objective for one of the parameters, TSP. However, the province of Ontario does provide ambient air quality criteria (AAQC) for many of the program PAH, VOC and metal parameters and these have been included in the tables for this section. Currently, Nova Scotia does not have an objective for PM10. Discussions with Environment Canada have determined that the use of criteria developed in other jurisdictions is acceptable. For the Sydney AAMP, a 24-hour criterion of 50 µg/m3 for PM10 has been applied, which is the criterion being used in Ontario and British Columbia. The monitoring locations at the perimeter of the Coke Ovens site are the exception, where a 24-hour criterion of 25 µg/m3 for PM10 has been applied during periods of activity at the site, as developed in the Interim Separation Zone criteria study (AGRA, 2000). Criteria for metals, PAHs and VOCs were also developed in the Interim Separation Zone study, to be applied around the perimeter of the Coke Ovens site during periods of activity at the Coke Ovens site. 3.1 PM10, TSP AND METALS RESULTS Tables 7 and 8 provide a summary of PM10, TSP and metals results for the February 8th and 20th sampling events, respectively.

Nova Scotia provides a 24-hour objective of 120 µg/m3 for the TSP parameter and the Ontario Ministry of Environment (MOE) provides a 24-hour AAQC of 50 µg/m3 for the PM10 parameter. A comparison of the TSP results with the Nova Scotia objective and the PM10 results with MOE AAQC indicates there were no exceedances for these parameters during the month of February. It is noted that the total mass for the metals reported exceeded the TSP gravimetric result at the Victoria Road location. Hence, the TSP result was rejected. A comparison of metals results for PM10 to regulatory criteria could not be performed since there are currently no regulations or guidelines for Nova Scotia, the rest of Canada nor the United States for metals that are sampled from the PM10 fraction. There were no exceedances to available metals AAQC for the Victoria Road, Frederick Street and Henry Street TSP samples. 3.1.1 PM2.5 Results Table 9 provides a summary of PM2.5 results for the February 8th and 20th events.

Notes: (1) CCME 24-hour Canada Wide Standard.

The Canadian Council of the Ministers of the Environment (CCME) provides a Canada wide Standard (CWS) of 30 µg/m3 for the PM2.5 parameter. A comparison of the PM2.5 results with the CWS indicates there were no exceedances during the month of February. It is also noted that on February 20th, the Henry Street PM2.5 result is higher than the TSP result for the same location. The TSP result is considered anomalously low, since PM2.5 is a part of


TV21233 14

TSP, and therefore, should never be lower than PM2.5. The reason for this anomalous result is unknown. Probable explanations include a loss of a portion of filter in the field or laboratory error. Since the total mass for metals did not exceed the TSP result, the sample was not rejected but considered biased low. 3.2 PAH RESULTS Tables 10 and 11 provide a summary of PAH results for the February 8th and 20th sampling events, respectively.

All results for naphthalene and benzo(a)pyrene were below the Ontario Ministry of the Environment 24-hour criteria. It is noted that the total PAH results are higher at the Henry Street location compared to the rest of the locations for both sampling events. Smoke-like odours were noted during the February 20th event. It is likely that this location is being impacted from emissions originating from the chimneys of residential units located in the vicinity of the sampling location. The same is likely for February 8th when a higher PM2.5 value was reported for Henry Street than other locations. 3.3 VOC RESULTS Tables 12 and 13 provide a summary of VOC results for the February 8th and 20th sampling events. A VOC duplicate sample was collected on February 20th at the Intercolonial Street location and this duplicate set of samples was forwarded to Environment Canada (EC) for further analysis. A copy of the EC results is contained in Appendix “C”.

Currently, there are no ambient air regulations or guidelines for Nova Scotia covering the VOC parameters. The Province of Ontario provides guidelines for most of the parameters identified in Tables 12 and 13 and these guidelines have been included for comparison with the measured concentrations. A review of results compared to the Ontario AAQC indicates that all results are below the guideline values. 3.4 PROGRAM QA/QC Refer to Appendix “B” for a copy of the February Data Validation Report. The data generated for this program are supported by quality assurance/quality control measures and can be relied upon for program purposes. Accuracy, precision and completeness met or exceeded program objectives for most analyses. The uncertainties in measurements that exist in the data set for VOCs and metals are primarily reflections of the low levels of compounds present in the ambient air. VOCs and metals, when detected, were essentially just above the laboratory method detection limit, and well below the referenced guidelines. With very limited exceptions, the data, taking into consideration the qualifications applied from validation, may be used with confidence for air quality characterization. The text for the February Data Validation Report details the reasons for all qualifications to data. Quantitative results may be qualified as estimated for a variety of reasons including: measurements below the demonstrated linear range of the instrument; high or low recoveries of surrogate compounds or matrix spike compounds (samples to which target compounds have been added); canister flow uncertainties; and changes in the pressure of a canister between the end of the sampling event and receipt at the lab. The bottom line is that the identification is reliable but the measured concentration has a degree of uncertainty to it. When possible, the text provided limits to this uncertainty; for example, if the surrogate recovery is low, the sample results are likely low to a comparable degree and low surrogate recovery probably indicates that the measured result represents only a portion of the actual air concentration. In many cases, however, it is not possible to establish clear limits for the uncertainty. The sample specific reasons for data qualification are summarized in the footnotes of the tables in Sections 3.1 to 3.3 and detailed in Appendix “B”. The following provides a summary of the data validation findings for the VOC, PAH and metals parameters.


TV21233 17

3.4.1 VOCs Most volatiles detected were at concentrations less than one half the low calibration standard and are qualified as estimated (JC) since the linearity of the instrument response cannot be assumed. Results for dichloromethane (methylene chloride) have been qualified as non-detected with elevated reporting limits as a result of laboratory background (UB). Table 14 presents data for the replicate analyses of field duplicate samples by PSC and EC collected on February 20th at the Intercolonial Street location. All detected analytes present were below ½ the low calibration standard at PSC and are qualified as estimated. Concentrations reported by EC were consistently higher by a factor of approximately two. The EC analyses are conducted using a different technique that provides lower detection limits for target analytes; differences in results between the two laboratories near or at the PSC reporting limits are within method expectations.

U = Non-detected at the stated limit. UB = Non-detected with elevated reporting limit as a result of background laboratory and/or canister contamination RPD = relative percent difference.

3.4.2 PAHs Results for naphthalene from the February 8th sampling event are qualified as estimated with potential low bias as a result of recoveries below 60% from the matrix spike samples. Naphthalene was also present in the February 8th field blank, but at a trace level that affected only the Kings Road sample result. Naphthalene was also present in the method blank for the February 20th; therefore results for all samples in this set except the Henry Street sample were qualified as non-detected with elevated reporting limits. 3.4.3 Metals No metals were detected in the method blanks or field blanks for the PM10 and TSP samples. Gravimetric results for TSP for the Victoria Road sample on February 20th were rejected since the mass of individual metals reported exceeded the reported TSP. The TSP result for Henry Street is considered biased low (BL) because the PM2.5 result is higher than the TSP result. The TSP result could not be rejected because the mass of individual metals does not exceed the TSP value.

4.0 YEAR TO DATE AVERAGES, MAXIMUMS AND MINIMUMS This section provides a summary, including running averages, maximum and minimums, of the last 12 months of program data (March 2002 to February 2003). Refer to Tables 15, 18 and 19 for a summary of the PM10/metals, PAH and VOC for the March 2002 to February 2003 time period, respectively. Table 16 presents the summary for the PM2.5, which includes sampling performed for the time period of December 2002 to February 2003. TSP and metals results summarized for the time period of July 31st, 2002 to the end of February 2003 are contained in Table 17. It should be noted that averages were not calculated for sample sets where all results were reported as below the method detection limit. For sample sets where at least one value in the sample set is reported as above the method detection limit, the values below the method detection limit are used in the calculation of averages by inputting values at half the reported method detection limit. In some instances there is an average value reported when the maximum is reported as below the method detection limit. The reason is that there was at least one value reported in the data set as being detected and the value(s) happens to be below the maximum reported detection limit on the tables.

Sampling Equipment and Procedure Description

PM10 Units Air sampling for PM10 is performed with a high volume sampler. Refer to Figure A1 for a sketch of the PM10 unit. The sampler consists of a size selective inlet, a filter holder, an air mover, a flow controller, and a timer. The unit works by drawing air into a size selective inlet at a flow rate, which is typically 40 ft3/min. Particles with aerodynamic diameters less than the cut point (less than 10 microns in diameter) are collected by the filter. The mass of the particles is determined by the difference in filter weights prior to and after sampling. The concentration of suspended particulate matter in the designated size range is calculated by dividing the weight gain of the filter by the volume of air sampled.

Figure A1

The main steps involved in sampling include the following:

1. Filter preparation by the Environmental Services Laboratory (ESL). 2. Installing the filter in the high volume sampler. 3. Setting the samplers timer so that it will turn on at midnight of the day of setup.

Checking the flow for a five-minute period to ensure the high volume sampler is operating properly. Inspecting the filter during the five-minute operation to ensure that the filter is installed correctly and is not damaged.

4. Performing periodic flow checks during the 24 hour sampling period to ensure the sampler is operating properly.

5. The sampler shuts off automatically after 24 hours (midnight) and AMEC collects the filter the following morning and transports it to ESL for PM10 and metals analysis. AMEC uses the field pressure measurements and laboratory results to calculate a concentration, which is reported in the monthly reports.

PM2.5 Units Air sampling for PM2.5 in air is performed with a low volume sampler. Refer to Figure A2 for a sketch of the PM2.5 unit. The sampler consists of a size selective inlet, a filter holder, an air mover, a flow controller, and a timer. The unit works by drawing air into a size selective inlet at a flow rate, which is typically 16.7 L/min. Particles with aerodynamic diameters less than the cut point (less than 2.5 microns) are collected by the filter. The mass of the particles is determined by the difference in filter weights prior to and after sampling. The concentration of suspended particulate matter in the designated size range is calculated by dividing the weight gain of the filter by the volume of air sampled.

setup. Checking the flow for a five-minute period to ensure the low volume sampler is operating properly.


5. The sampler shuts off automatically after 24 hours (midnight) and AMEC collects the filter the following morning and transports it to ESL for PM2.5 and metals analysis. AMEC uses the field pressure measurements and laboratory results to calculate a concentration, which is reported in the monthly reports.

PAH Units Air sampling for PAHs in air is performed with a high volume sampler. Refer to Figure A3 for a sketch of the PAH unit. The sampler consists of a module containing a filter holder and polyurethane foam (PUF) backup media, an air mover, a flow controller, and a timer. The unit works by drawing air over a module at a flow rate, which is typically 7.9 ft3/min. PAH particulate matter is captured on a filter at the front of the PUF module, and the vapor phase of the PAHs is captured in the PUF foam backup.

5. The sampler shuts off automatically after 24 hours (midnight) and AMEC collects the module the following morning and transports it to ESL for PAH analysis. AMEC uses the field pressure measurements and laboratory results to calculate a concentration, which is reported in the monthly reports.

Evacuated Canisters Air sampling for VOCs in air is performed with an evacuated canister. The sampler consists of a stainless steel canister, and a sampling tip with a flow restrictive orifice. The unit works by drawing in air through the evacuation of the canister (under negative pressure) through the flow restrictive orifice filling the 1.7 litre canister over a 24 hour period. VOCs will be captured in the canister, where they are analyzed at Phillip Analytical Laboratories in Burlington, Ontario.

restrictive tip. 3. Checking the initial pressure of the canister to ensure it is useable for sampling. 4. Manually opening the canister valve at midnight on the day of sampling to start

the evacuation (sampling) process. 5. Manually closing the canister valve the following midnight (24 hours later) on the

day sampling is complete in order to end the evacuation process. 6. Checking the final pressure in the canister to ensure that a complete sample was

obtained. 7. AMEC collects the canister the following morning and ships it to PSC for VOC

analysis. AMEC receives the laboratory results, which are converted to µg/m3, and are then reported in the monthly reports.

Subject Muggah Creek Air Monitoring

Draft Data Validation Report – February Sampling Events INTRODUCTION Data for the analyses of air samples collected during February 2003 in support of the Muggah Creek Remediation Project in Sydney, Nova Scotia have been reviewed. These samples were collected on February 8 and 20, 2003 at the program’s established monitoring locations in Sydney, Nova Scotia. Samples included in this review are listed in Table 1. Samples were collected in evacuated canisters for analyses for volatile organic compounds (VOC) in accordance with U. S. EPA Method TO-14A; for polyaromatic hydrocarbons (PAH) on glass fiber filters and polyurethane foam plugs (PUF) in accordance with Method TO13A; and for metals on quartz filters. Metals samples included the collection of filters for total suspended particulate (TSP) as well as particulate matter with aerodynamic diameters of 10 microns or less (PM10) on quartz fiber filters. Particulate matter with a diameter of 2.5 microns or less (PM2.5) was collected this month on PTFE Teflon Membrane Filters. Philip Analytical Services (PSC) of Burlington, Ontario conducted analyses for VOC, Environmental Services Laboratory (ESL) of Sydney, Nova Scotia conducted analyses for PAH, particulates (TSP, PM10) and metals, and the Chester LabNET in Tigard, Oregon conducted the analyses for the PM2.5. Data validation was conducted based upon reported results for quality control/quality assurance measures and consistent with U.S. EPA guidance for data review and evaluation. SUMMARY OF VALIDATION FINDINGS Results for volatile organics, PAH and metals have been validated. Quality assurance/quality control measures met or exceeded method requirements with exceptions as discussed in the report. Although individual data points have been qualified for a variety of quality-assurance related issues, results as included in the final validated set are appropriate for use in characterizing the quality of the airshed in Sydney, Nova Scotia during the monitoring events. Qualifications to results are summarized below: Volatile Organics ! Most volatiles detected were at concentrations less than one half the low calibration

standard and are qualified as estimated (JC) since the linearity of the instrument response cannot be assumed.

! Results for dichloromethane (methylene chloride) have been qualified as non-detected with elevated reporting limits as a result of laboratory background (UB).

2

Validated data for VOC are presented in Tables 2 and 3. Table 5 presents data for the analyses of field duplicate samples by PSC and Environment Canada. PAH Results for naphthalene from the February 8, 2003 sampling event are qualified as estimated with potential low bias as a result of recoveries below 60% from the matrix spike samples. Naphthalene was also present in the February 8, 2003 field blank, but at a trace level that affected only the Kings Road sample result. Naphthalene was also present in the method blank for the February 20, 2003; results for all samples in this set except the Henry Street sample were qualified as non-detected with elevated reporting limits. Validated data for PAH are presented in Tables 5 and 6. Results for field duplicates are presented in Table 7. Metals and Particulates Results for metals and particulates are presented in Tables 8 through 10. No metals were detected in the Method Blanks or Field Blanks for the PM10 and TSP samples. Gravimetric results for TSP for the Victoria Road sample on February 20th were rejected since the mass of individual metals reported exceeded the reported TSP. The TSP result for Henry Street is considered biased low because the PM2.5 result is higher than the TSP result. The TSP result could not be rejected because the mass of individual metals does not exceed the TSP value. REVIEW ELEMENTS Data validation included review and evaluation of the following elements:

1. Sampling records 2. Chain of Custody documentation 3. Holding times 4. Canister certification analyses (VOC samples) 5. Canister pressure after sampling and upon laboratory receipt (VOC samples) 6. Method blanks 7. Laboratory spike samples 8. Matrix spike samples 9. Sample duplicate analyses 10. Internal Standard recoveries (VOC) 11. Surrogate recoveries (PAH) 12. Field blanks

Only those areas where discrepancies or anomalous results were noted are discussed below. The attached data tables indicate specific samples affected by these instances. VOLATILE ORGANIC ANALYSES

Method Blank and Canister Certification Analyses Dichloromethane was detected in the method blanks and certification analyses at concentrations ranging up to 0.68 ppbv. U.S. EPA guidance followed for this review directs that data for common laboratory chemicals such as dichloromethane be qualified unless the analyte is detected at 10

3

times above the level in the associated blanks. Unless this is the case, sample analysis results are considered potentially attributable to the laboratory background and dichloromethane is reported as non-detected with reporting limits set at the concentrations actually detected during the analyses (UB). PSC flagged all dichloromethane results as potentially attributable to laboratory background. Dichloromethane in all samples has been qualified as non-detected (UB) with reporting limits set at the concentrations detected in the individual samples.

Canister Pressure Readings The pressure of the canister is measured in the field at the end of the sampling event and then again by the laboratory prior to analysis. Sampling flows are designed so that canisters will still be at negative pressure (under vacuum) at the end of each sampling event. The readings at the laboratory are taken to confirm that in-leakage of air through the valve has not occurred during shipment or storage. There were no pressure anomalies for samples collected in February 2003.

Matrix Spike Analysis The matrix spikes prepared and analyzed with the field samples demonstrated recoveries within acceptance limits. Internal Standards Internal standards added to samples are used to quantify detected target analytes. Their recovery is monitored as a measure of the overall accuracy of the analysis. All internal standards recoveries were within acceptance limits. Field Duplicates and Quality Control Analyses by Environment Canada Field duplicate samples were collected at the Intercolonial Street location on February 20, 2003. Results for the analyses at PSC and Environment Canada (EC) are presented in Table 4. All detected analytes present were below ½ the low calibration standard at PSC and are qualified as estimated. Concentrations reported by EC were consistently higher by a factor of approximately two. The EC analyses are conducted using a different technique that provides lower detection limits for target analytes; differences in results between the two laboratories near or at the PSC reporting limits are within method expectations. PAH ANALYSES The recovery of naphthalene for the matrix spike associated with the February 8, 2003 samples was 55%, below the method control limit of 60%. Results for naphthalene in these samples are qualified as estimated with a potential low bias. In addition, the field blank collected February 8, 2003 contained a trace level (0.09 µg) of naphthalene. Naphthalene in all samples except the Kings Road sample was greater than 10 times above the level in the associated blanks; the result for Kings Road was qualified as non-detected with an elevated reporting limit and data for other samples were accepted with qualification as noted above. The method blank for the February 20, 2003 samples contained naphthalene at a concentration such that results for all samples except the Henry Street sample could potentially be attributed to background laboratory contamination. Results have been qualified as non-detected with reporting limits set at the concentrations noted in the individual samples.

Field duplicate PAH results as presented in Table 7. Results for the Frederick Street samples on February 20, 2003 demonstrated acceptable agreement for all analytes. METALS ANALYSES Method and Field Blanks Method and field blanks for the analyses of quartz filters were reported to have no detectable metals. Gravimetric Analyses – PM2.5, PM10 and TSP Both field blanks for PM10 and TSP on February 8, 2003 contained trace levels of particulate. Sample results were all greater than 10 times the blank, so results have not been qualified. Results for TSP for the Victoria Road sample on February 20, 2003 were rejected. The total mass of metals reported for this filter exceeded the TSP mass, indicating either a laboratory error or a possible tear or loss of a small fragment of the filter material. Results for TSP for the February 20, 2003 Henry Street sample are considered biased low (BL) since the PM2.5 result is anomously higher than the TSP result for the same location.
