1.0 INTRODUCTION Golder Associates Ltd. (Golder) was retained by The City of Barrie (The City) to assist with an assessment of

odour and potential health impacts related to air quality at The City of Barrie Landfill Site (The Site) in relation to

ongoing landfill reclamation and waste placement operations. Local residents have expressed concerns with the

potential health impacts from landfill gas discharge and the use of odour control suppression products during the

reclamation process. In response to these concerns, the City requested Golder to obtain data to assess air

quality within the landfill operation area as well as ambient air quality at the Site boundary. The following

document outlines the procedures undertaken and summarizes the results of the sampling at the Site. Analysis

of results will be provided separately as part of an Odour and Health Risk Assessment study.



2.0 SAMPLING APPROACH Sampling was undertaken at the Site using (i) the US EPA approved method of summa canister sampling; and

(ii) the NIOSH method 6016 with solid sorbent tubes. Both grab samples and ambient samples were collected.

Grab samples were collected over a short time period from concentrated source areas such as landfill gas

observation wells; ambient samples of the air in the vicinity of the summa canisters were collected over a longer

(eight hour) period.

Summa canister samples were analyzed for a wide range of compounds including VOCs, matrix gases and

sulphur compounds. Summa canisters are cylindrical containers that have been evacuated into a vacuum. By

opening a valve, the negative pressure in the canister acts to draw air in and the canister fills automatically. The

contents of the canister are later analyzed by a laboratory. Summa canisters can be used to sample for set

periods of time using a flow controller. They can thus be used to collect grab samples or to sample slowly and

continuously over a period of several or more hours. Both types of sampling were conducted at the Site.

Passive samples were collected over an eight (8) hour sampling period at five (5) sampling locations on

August 26, 2010; grab samples were collected at four (4) point source sampling locations on September 9, 2010.

For QA/QC purposes, the passive sampling round was repeated on September 10, 2010.

Ammonia sampling was conducted using solid sorbent tubes and sampling pumps to sample air at a known flow

rate. Passive samples were collected over a four (4) hour sampling period at the five (5) ambient sampling

locations on August 26, 2010; five minute grab samples were taken at the four (4) point source sampling

locations on September 9, 2010.

A photograph of the equipment set up in one of the ambient sampling locations is included in Appendix A.

2.1 Sampling Locations A total of nine sampling locations were identified. The approximate location of each sampling point is identified

on Figure 1. The ambient sampling locations were selected based on the prevailing wind from the northwest,

which is reported to result in odours typically near the intersection of Edgehill Drive and Jagges Drive. The

individual locations were then selected downwind of the potential main sources of odour from the Site. The point

source (referred to as enclosed) sampling locations were selected to collect raw samples of landfill gases from

different areas of the Site. The results were used to help characterize the gases generated by different

processes and in different areas of the Site. A brief description of each sampling location and reasons for

selection are discussed in the following sections. Photographs of each ambient sampling location are included

in Appendix B.

2.1.1 Ambient Sampling Locations

1) This sampling point is located at the north-western corner of the Site and lies upwind of Site activities.

Consequently this sampling point was selected to assess background conditions.

2) This sampling point is located approximately 50 m downwind of the waste reclamation area (Cell 3B)

and represents fugitive emissions from the waste reclamation activities. It is situated approximately



400 m from the closest Site boundary to the south (near Edgehill Drive). This sampling point was

selected to represent air quality in the immediate vicinity of the reclamation activities.

3) This sampling point is located approximately 50 m downwind of the active filling area in Cell 2A and

represents fugitive emissions form the ongoing landfill activities. It is situated approximately 300 m from

the closest Site boundary to the south. This sampling point was selected to represent air quality in the

immediate vicinity of waste placement activities in addition to any impacts migrating from the upwind

reclamation area.

4) This sampling point is located on the southern Site boundary along a corridor formed by a cut line in the

trees south of the west side of the Site and leading towards Edgehill Drive on the west side of the Site.

It has been reported that odour has been detected along this corridor, which is in the vicinity of the

completed Cell 3A where landfill gas odours have been identified. This is also the location of the

discharge sewer from the leachate collection system and purge wells. Consequently, this sampling

location was selected to characterize odours in this area of the Site.

5) This sampling point is located on the southern boundary of the Site, at the bottom of a corridor formed

by a cut line in the trees south of the landfill, which leads from the Cell 1 /Cell 2 boundary in the direction

of Jagges Drive. This sampling point was selected because it is downwind of the Site (notably the

reclamation and filling areas) and lies very close to the Edgehill Drive/Jagges Drive intersection, where

odours have been reported.

2.1.2 Enclosed Sampling Locations

ES-1) This sampling point is located within the stone drainage material on the west side of Cell 3A. It was

selected to characterize landfill gas emissions from this recently completed cell, which has occasionally

produced odours along the west haul road.

ES-2) This sampling point is a landfill gas well located in Cell 3A. It was selected to help characterize landfill

gas from the recently completed waste cell.

ES-3) This sampling point is a landfill gas observation well located in Cell 2C. It was selected to help

characterize landfill gas from Cell 2, an older part of the landfill which will be reclaimed in future.

ES-4) This sampling point is the leachate collection system drop manhole located immediately downstream of

Cell 3A. It was selected to help characterize gases from the leachate collection system;



3.0 FIELD OBSERVATIONS Sampling was undertaken during a period when waste screening activities were underway. During this time,

moderate, primarily north-westerly winds were recorded, ranging from 19 km/hr to 26 km/hr on August 26 and

11 km/hr to 19 km/hr on September 10. During the first sampling round, weak to moderate off-site odours were

observed throughout the day along Edgehill Drive, Bird Street, Gross Drive, Ruffet Drive and Villers Street; all of

which lie to the south of the Site. Weak odour was also observed at 13:30 on Ferndale Drive, which lies east of

the Site. Off-site odours were reported to be non-existent during the second sampling round. During the

August 26th sampling period, odour misters were used at the active filling and reclamation areas and perimeter

roads were sprayed with water containing odour suppressant. During the September 10th sampling round, only

one odour mister was in operation at the reclamation area.

All samples in each monitoring round were started and stopped within a half hour of one another over the course

of a day to minimize the effect of changing meteorological conditions. During each sampling period, no

significant variation or changes in meteorological conditions were observed and there was no precipitation.

Meteorological conditions and off-site odours were recorded regularly and are listed in Tables 1, 2 and 3, below.

Copies of all field notes are provided in Appendix C.

City staff undertake regular odour detection drives in the neighbourhoods surrounding the Site. These drives are

completed hourly during regular reclamation operations. Operations at the Site are adjusted in order to minimize

the impact of the odours off-Site.

Odours detected on the drives are assessed on a scale of 1 to 10, as follows:

0 No detectable odour

1 ‐ 2 Faint to Mild 3 ‐ 4 Moderate 5 ‐ 6 Strong 7 ‐ 8 Very Strong 9 ‐10 Extreme

The results of the odour assessments on the days during which the air quality samples were collected are listed in Table 3.

4.0 RESULTS Collected samples were sent back to the laboratory for analysis of matrix gases, sulphur compounds, VOCs and

ammonia. The results are presented in the Tables 4 through 7. Full copies of the monitoring results are

provided in Appendix D.

The results indicate that sample AS-1 contained low concentrations of 2-propanone, Freon 11, Freon 12 and

methylene chloride. All other VOCs, ammonia and sulphur compounds are below detection limits. This

sampling point is upwind of the Site and is anticipated to represent typical background concentrations.

Sample AS-2 was collected 50 m downwind of the waste reclamation area, whereas AS-3 was collected 50 m

downwind of the active filling area. These samples generally have greater VOC concentrations compared to the

upwind sample (AS-1) including a larger number of VOCs at concentrations greater than the detection limits,

including ethanol, toluene and xylenes. On the whole, samples AS-2 and AS-3 have very similar compositions.

The main differences are that the reclamation area sample (AS-2) contains benzene and ammonia, whereas

these compounds were below the limits of detection in the active filling area sample (AS-3). Conversely, sample

AS-3 contains a higher concentration of ethanol as compared to sample AS-2.

Samples AS-4 and AS-5 were both collected downwind of the Site along the Site boundary. Both of these

samples have a very similar composition to the upwind sample (AS-1). The concentrations of ammonia, sulphur

compounds and most VOCs were below detectable limits. The only additional parameter that was detected in

these samples was ethanol, which is not present above detectable limits in the upwind sample, but is present in

both of these site boundary samples at concentrations just above the detection limits. There is very little

difference in the composition of the two site boundary samples.

There is a significant difference in the composition of the samples from gas collected from the older

(ES-3, Cell 2) and newer (ES-2, Cell 3A) waste. Both samples contain hydrogen sulphide and other sulphur

compounds however, the concentrations are generally much higher in the sample taken from the more recently

filled cell (ES-2). Additionally, sample ES-2 generally contained higher VOC concentrations than the older waste

cell sample. In particular, there were much higher concentrations of chloroethane, tetrachloroethylene, propene,

toluene and vinyl chloride in the sample taken from Cell 3A. In contrast, benzene and chlorobenzene were

present in much greater concentrations in the Cell 2 sample. Ammonia was detected in Cell 2 but was below the

detection limit in Cell 3A.

The sample collected from the stone drainage material (ES-1) contains the greatest number of VOCs of any of

the samples, but these were generally at lower concentrations than either of the in-waste samples (ES-2 and

ES-3) with the exception of 1,1,1 trichloroethane, 1,1 dichloroethane, 1, 1 dichloroethylene, tetrachloroethylene,

trichloroethylene and trichlorotrifluoroethane. Concentrations of sulphur compounds and ammonia were below

the limits of detection in the ES-1 sample.

The leachate drop manhole sample (ES-4) contained low concentrations of VOCs, most of which were below the

limits of detection. The sample composition was very similar to that of the upwind sample (AS-1) and was

differentiated only by additional small concentrations of 1,1 dichloroethylene, benzene, chlorobenzene and

propene in the ES-4 sample.

Overall, the sampling results indicate that sulphur compounds, which are most commonly associated with odour,

were only observed above detection limits in the samples collected directly from within the waste (i.e., ES-2 and



ES-3). This suggests that concentrations of sulphur compounds off-site are low, although perception of sulphur

odours may occur at levels much lower than the analytical detection limits. Conversely, ammonia, which is also

associated with odours, was only observed in samples immediately downwind from the reclamation area (AS-2)

and an in-waste sample from Cell 2, which contains slightly older waste (ES-3). Ammonia has a very distinctive

odour. Reported site odours considered to be related to ammonia were observed to be most prevalent during

waste excavation and therefore are considered to originate from the older waste.

Ethanol was observed in samples AS-3 and AS-4, which lie just downwind of the reclamation area and active

filling areas respectively but was only observed in significantly lower concentrations in any of the other samples,

including those from the waste. The source of these ethanol concentrations is thus anticipated to be the odour

suppressant chemicals which were used during reclamation and filling activities at the time of sampling. The

chemical ingredients of the odour suppressants used on-Site include isopropyl alcohol but information on any

other ingredients is proprietary to the manufacturer.

Overall, the sampling results indicate that the Site boundary samples have few detectable concentrations of the

analyzed parameters. The downwind boundary samples have a very similar composition to the upwind sample

thus indicating that the concentrations of landfill related compounds (e.g., ammonia, sulphur compounds and

VOCs off-site) are close to background concentrations. It is noted however that perception of odour can occur at

very low levels. Odours were observed south of the Site during the first monitoring round but not during the

second monitoring round. This is supported by the variation in compositions between the two sampling rounds.

Generally, VOC concentrations were slightly greater at all ambient locations during the first monitoring round;

however the downwind samples taken at the Site boundary still had low concentrations of all monitored

compounds, and most were below the limits of detection.

(1) GC/FPD (Gas Chromatography/Flame Photometric Detection)(2) Air sampling canisters have been cleaned in accordance with U.S. EPA Method TO14A. At the end of the cleaning, evacuation, andpressurization cycles, one canister was selected and was pressurized with Zero Air. This canister was then analyzed via TO14A on aGC/MS. The canister must have been found to contain <0.2 ppbv concentration of all target analytes in order for the batch to have beenconsidered clean. Each canister also underwent a leak check prior to shipment.

Please Note: SUMMA® canister samples will be retained by Maxxam for a period of 5 calendar days from the date of this report, after whichtime they will be cleaned for reuse. If you require a longer sample storage period, please contact your service representative.

GENERAL COMMENTS

Matrix Gas/Sulfur Analysis: Canisters were pressurized with Helium to enable sampling. Results and DLs adjusted accordingly.

Sample HC8475-01: Canister received at 0psig and was pressurized to 22psig with helium, for a 2.5x pressure dilution.A 5x dilution was prepared and analyzed, resulting in a 12.5x final dilution. The sample was rerun for propene and toluene at a 10x dilution,resulting in a 25x final dilution. DLs adjusted accordingly.Increased the DL further for methylene chloride, carbon disulphide and ethanol due to possible background.

Sample HC8476-01: Canister received at 0psig and was pressurized to 12psig, for a 1.8x pressure dilution.A 50x dilution was prepared and analyzed, resulting in a 90x final dilution. DLs adjusted accordingly.Increased the DL further for methylene chloride, carbon disulphide and ethanol due to possible background.

Sample HC8477-01: Canister received at 0psig and was pressurized to 12psig with helium, for a 1.8x pressure dilution.A 20x dilution was prepared and analyzed, resulting in a 36x final dilution. DLs adjusted accordingly.Increased the DL further for methylene chloride, carbon disulphide and ethanol due to possible background.

Sample HC8478-01: Canister received at 0psig and was pressurized to 12psig, for a 1.8X pressure dilution. 100mL of sample was analyzed,resulting in a 1.8X final dilution. The DLs were adjusted accordingly
