1. Introduction
DST Consulting Engineers Inc. (DST) was retained by MHPM Project Managers Inc. (MHPM)
on behalf of the Ottawa Humane Society (OHS) to complete a Phase II Environmental Site
Assessment (ESA) for part of a property located at 271 West Hunt Club Road, Ottawa, Ontario,
referred to as “Parcel A” (the “site”) (Figure 1).
The purpose of this work was to evaluate the environmental quality of soil and groundwater at
the subject site. Authorization to proceed with this work was received from Mr. Greg Ashley of
MHPM on October 17, 2007.
DST has prepared this report for the exclusive use of OHS and/or its agents in evaluating the
environmental condition of the site at the time of field investigation. DST will not be responsible
for the use of this report by any third party, or reliance on or any decision to be made based on

2. Background
2.1 Site Description The subject site is a triangle-shaped parcel of land located at 271 West Hunt Club Road (Figure
1). Access to the site is provided via a private asphalt road off the north side of West Hunt Club
Road. The subject site is part of a larger vacant land and is referred to as “Parcel A”. The site
area is approximately 1.2 ha, and is covered by tall grass and shrubs. The Ottawa Central
Railway runs along the north-western boundary of the site. Canadian Pacific Railway is located
approximately 80 m south-east of the site, and West Hunt Club Road is located approximately
150 m southwest of the site. The lands immediately adjacent to the south-eastern and south-
western boundaries of the site are vacant. The topography on the property and immediate areas
is flat, with the exception of the raised railway alignments. A Site Plan has been included as
Figure 1, Appendix A. Photographs of the site have been included in Appendix C.
2.2 Background A Phase II ESA was previously carried out for a larger parcel of land which included “Parcel A”
by John D. Patterson and Associates Ltd. (Patterson) entitled “Phase II Environmental Site
Assessment, Undeveloped Property, Part of Lots 28 and 29, Concession ‘A’ (Rideau front),
Hunt Club Road, City of Nepean, Ontario”, July 10, 2000, File No. E1621-01.LET. The previous
Phase II ESA covered a larger area including the subject site; however, laboratory analyses
were not specifically completed for “Parcel A” to evaluate the environmental quality of the soil
and groundwater. The site is located within an industrial setting, with present and historical
operations of a nearby bulk fuel terminal and the adjacent railway lines. Thus, DST
recommended a site-specific Phase II ESA be conducted in accordance with O. Reg. 153.

3. Scope of Work
In order to assess the environmental quality of soil and groundwater at the site, the following
scope of work was developed, in consultation with MHPM:
• Advancement of three boreholes, all of which converted to monitoring wells, to
assess the presence or absence of soil and groundwater contamination at the
subject site;
• Submission of one soil sample and one groundwater sample collected from each
borehole/monitoring well location for laboratory chemical analyses of petroleum
hydrocarbons fraction F1 to F4 (PHC F1-F4) and benzene, toluene, ethylbenzene,
and xylenes (BTEX); and
• Preparation of a report documenting the results of the investigation, including
borehole logs, results of soil and groundwater sample analyses, comparison of
analytical results to appropriate regulatory standards and the presentation of the
conclusions and recommendations of the assessment.

4. Methodology
4.1 Subsurface Investigation The field program was carried out at the subject site on November 15, 2007. A total of three
boreholes, all of which converted to monitoring wells, were completed to depths ranging from
5.5 to 6.1 m below existing surface grade using a tack-mounted CME 55 drilling rig equipped
with hollow-stem augers and split spoon samplers.
Borehole/monitoring well locations are indicated on Figure 1, Appendix A. Borehole logs are
included in Appendix D.
4.2 Soil Sampling Program A trained DST staff continuously supervised all drilling activities, and collected soil samples for
lithologic logging, field screening, and laboratory analyses. All soil samples were collected in
accordance with applicable environmental guidance manuals and applicable industry practices.
Soil samples were screened in the field using an RKI Eagle 101 catalytic combustible gas
detector (CCGD), and visual/olfactory observations. The screening for relative organic vapours
(ROV) was carried out on a portion of soil sample using the CCGD operating in the methane
elimination mode. The readings provide a measure of relative organic vapour levels, due to
presence of potential hydrocarbon contaminants, between soil samples; thus, providing a tool in
the evaluation of the presence of potential subsurface contamination. The CCGD readings, in
parts per million (ppm) hexane equivalent, are provided on the borehole logs in Appendix D. All
recovered soil samples were also visually described and classified as per standard procedures
outlined in the Canadian Foundation Engineering manual (CFEM, 2006). The general soil
stratigraphy of the the subject site is characterized by a top layer of silty sand to depths ranging
between 1.5 m to 1.7 m below the existing grade, followed by a silty clay layer at depths.
Soil from each recovered sample was placed directly into a laboratory supplied glass sample
jars. All soil samples were placed in an ice-packed cooler prior to and during shipment to
Maxxam Analytics Inc. (Maxxam) for chemical analyses. The criteria for selection of soil
samples for laboratory analyses were based on the results of field screening, and
visual/olfactory observations. A total of three soil samples, one from each borehole/monitoring
well, were submitted for laboratory analysis of PHC F1-F4 and BTEX.

4.3 Monitoring Well Installation and Groundwater Sampling Program
A groundwater monitoring well was installed in each of the three boreholes to facilitate the
collection of groundwater samples. The monitoring wells were installed in accordance with the
Ontario Water Resources Act – R.R.O. 1990, Regulation 903, as amended. The monitoring
wells were constructed using 50 mm diameter, schedule 40, flush-joint threaded polyvinyl
chloride (PVC) screen and riser. Details of the installed monitoring well at each borehole
location are provided on the borehole logs in Appendix D. Clean sand (sand pack) was added
around annular space of well screen to at least 30 cm above the top of the screen, followed by a
bentonite seal to approximately 30 cm below the existing ground surface. The tops of the riser
pipes, which extend approximately 1 m above ground surface, were sealed with a j-plug and
protected with a steel protective casing. The following table illustrates the borehole/monitoring
well IDs, the associated GPS coordinates, and the depths to the groundwater level (metres
below existing surface grade - mbsg).

BHMW2 444707 5021172 ±4 1.85
BHMW3 444662 5021122 ±7 1.88
All three monitoring wells were equipped with dedicated WaterraTM tubing and foot valves.
Before water sampling, each monitoring well was purged of approximately three volumes of
water or until dry to remove any residual sediment or drill cuttings. A total of three groundwater
samples (one from each monitoring well) were collected and submitted to Maxxam for chemical
analyses of PHC F1-F4 and BTEX. All sample containers were stored in cooler before and
during transportation to the laboratory.

4.4 Quality Assurance/Quality Control DST maintains a standard Quality Assurance/Quality Control (QA/QC) program for all Phase II
ESAs. The field sampling and QA/QC program was completed in accordance with the
applicable Guidance on Sampling and Analytical Methods for Use at Contaminated Site in
Ontario (MOE, 1996). Documentation of the field results such as location, weather, field
measurements, number of samples, parameters collected for, time sampled, volume,
hydrocarbon readings and equipment type were completed. All project documentation was
maintained and controlled under each specific work site and sampling area by the appointed
site supervisor. Boring, monitoring well installation, soil and groundwater sampling was
completed in accordance with industry standards, and applicable provincial guidelines/
standards. The soil samples were placed in laboratory supplied containers and maintained at
approximately 4°C in an ice chest, under a Chain of Custody protocol prior to being submitted
for chemical analyses to Maxxam, which is a certified laboratory by the Canadian Association
for Environmental Analytical Laboratories (CAEAL) and/or Standards Council of Canada (SCC).

5. Regulatory Criteria
The soil and groundwater sample analytical results were compared to the following standards:
• Ministry of Environment (MOE) Soil, Ground Water and Sediment Standards for use
Under Part XV.1 of the Environmental Protection Act – Table 3, Full Depth Generic Site
Condition Standards in A Non-Potable Ground Water Condition – “Industrial/
Commercial/ Community Property Use” for soil, and “All Types of Property Use” for
groundwater.
MOE Table 3 Standards apply to the site, as the vicinity area of the site is supplied by municipal
drinking water, and the site is not characterized as an environmentally sensitive site under the
Ontario Regulation (O.Reg.) 153/04. The subject property is located within an area of industrial
land use designation. The subject site consists of mixed fine and coarse soil material. As such,
the most stringent grain-size based MOE Table 3 criteria for soil and groundwater is used for
the current assessment.

6. Results and Discussion
The soil and groundwater analytical results are summarized in Table B-1 and Table B-2,
respectively. The Laboratory Certificates of Analysis are included in Appendix E.
6.1 Soil Investigation
6.1.1 Stratigraphy Based on soil data collected at the site, the subject site is characterized by a top layer of silty
sand at depth ranging between 1.5 m to 2.0 m below the existing surface grade, followed by
silty clay to depth. The borehole logs are included in Appendix D.
6.1.2 Field Screening Total hydrocarbon vapour concentration measurements recorded in the soil samples collected
at the subject property were found at various levels ranging from non-detectable to 100 ppm.
There was no visual or olfactory evidence of PHC impact observed in any of the samples
collected. No sheens, free-phase liquid petroleum hydrocarbons, or odour was noted during the
drilling and subsequent groundwater sampling activities. The gas detector readings are included
in the borehole logs in Appendix D.
6.1.3 Soil Analytical Results Based on a comparison of the soil sample laboratory analytical results with the MOE Table 3
standards, all soil samples met the applicable criteria for PHC F1-F4 and BTEX parameters.
6.1.4 Groundwater Analytical Results Based on a comparison of the groundwater sample laboratory analytical results with the MOE
Table 3 standards, all groundwater samples met the applicable criteria for PHC F1-F4 and
BTEX parameters.

7. Conclusions and Recommendations
DST Consulting Engineers Inc. (DST) has completed a Phase II Environmental Site
Assessment (ESA) at a Ottawa Humane Society property located at 271 West Hunt Club,
Ottawa, Ontario (the “site”). The subject site is referred to as “Parcel A” (Figure 1).
Three boreholes were advanced at the subject site, all of which were converted to monitoring
wells. One soil sample and one groundwater sample were collected from each of the
borehole/monitoring well locations, and were submitted to Maxxam Analytics Inc. for chemical
analyses of petroleum hydrocarbons fraction F1 to F4 (PHC F1-F4), benzene, ethylbenzene,
toluene, and xylene (BTEX).
Based on a comparison of the laboratory analytical results with the applicable provincial
standards (MOE, 2004: Table 3 industrial/ commercial/community property use) all soil and
groundwater samples submitted for analyses reported concentrations below the applicable
standard for all parameters analyzed. Therefore, there is no evidence that the contaminants of
concern are present at this site at concentrations exceeding the reference criteria.
The Ontario MOE Well Regulation 903 (O.Reg. 903) of the Ontario Water Resources Act
defines monitoring wells, standpipes, and open piezometers as a special type of well referred to
as “Test Hole”. As such, the monitoring wells installed at the subject site should be
decommissioned in accordance with O. Reg. 903, as amended.

Limitations of Report
Phase II Environmental Site Assessment 271 West Hunt Club Road, Ottawa, Ontario DST File No.: OEOT008007
DST Consulting Engineers Inc. November 2007
LIMITATIONS
The information, conclusions and recommendations given herein are specifically for this project
and this client only, and the scope of work described herein. It may not be sufficient for other
uses.
As documented in this report, some information used by DST Consulting Engineers Inc. (DST)
in this assessment has been obtained from various sources of information (i.e. laboratories)
believed to be reliable. Although our recommendations are partly based on such information,
our services did not include the verification of its accuracy or authenticity. Should such
information prove to be inaccurate or unreliable, DST reserves the right to amend or revise its
recommendation.
The conclusions and recommendations regarding environmental conditions, which are
presented in this report, are based on a scope of work authorized by the client. Note, however,
that virtually no scope of work, no matter how exhaustive, can identify all contaminants or all
conditions above and below ground. For example, conditions between test holes may differ
from those encountered in the investigation and conditions may change with time. This report
therefore cannot warrant that all conditions on or off the site are represented by those identified
at specific locations.
Note also that standards, guidelines and practices related to environmental investigations may
change with time. Those which were applied at the time of this investigation may be obsolete or
unacceptable at a later date.
The comments given in this report on potential remediation problems and possible methods are
intended only for the guidance of the designer. The scope of work may not be sufficient to
determine all of the factors that may affect construction or clean-up methods and costs.
Contractors bidding on this project or undertaking clean-ups should, therefore, make their own
interpretation of the factual information presented and draw their own conclusions as to how the
conditions may affect their work.
