EXECUTIVE SUMMARY

Pinchin Environmental Ltd. (“Pinchin”) was retained through an Authorization to Proceed signed by Mr. Daniel Drimmer of TransGlobe Property Management Services (the “Client”) to supervise a remedial excavation of suspect soils which underlie a current dry cleaning facility and perform a verification soil sampling program at the property referred to as the Herongate Mall located at 1670 Heron Road, Ottawa, Ontario (hereafter referred to as the “Site”). In order to address impacted groundwater, Pinchin was also authorized to complete the installation of an injection gallery and subsequent injections of an oxidizing solution to mitigate any residually impacted groundwater.

The Site is developed with one single-storey multi-tenant commercial building (the “Site Building”), situated in an area of predominant residential and commercial land use. Potable water is supplied to the Site through City of Ottawa municipal services which utilizes the Ottawa River as the potable water source.

The objective of the remedial excavation was to excavate the soils located beneath the dry cleaning equipment which were suspected of being a source of volatile organic compound (“VOC”) impacts which would exceed applicable Ontario Ministry of the Environment “(MOE”) clean-up standards. Removal of the potentially impacted subsurface materials would effectively eliminate any source for future contamination to the groundwater which underlies the Site and verify that the Site is in compliance with applicable MOE assessment standards.

The following is a summary of activities and results of this comprehensive remedial program conducted at the Site:

1. From September 28 through October 15, 2010, Pinchin field personnel were on-Site to supervise the excavation activities completed by Ontario Specialty Contracting (“OSC”). A mini-track driven excavator operated by OSC was used to remove the surficial concrete material and all accessible overburden soils;

2. Data collected during the excavation operations indicated that the subsurface material at the Site generally consisted of concrete underlain by a sand gravel fill material, successively underlain by native brown silt clay over bedrock, which was observed at a minimum depth of 5.5 meters below ground surface (“mbgs”);

3. Pinchin field personnel completed a field screening and segregation program using visual, olfactory and organic vapour measurements recorded using a photo-ionization detector (“PID”). The final limits of the excavation were extended until little or no visual or olfactory evidence of environmental impacts were observed.

4. The non-impacted soil was segregated from the impacted soil as a result of the field screening program and stockpiled on Site for reuse as fill material. The excavation area extended to a maximum depth of 4.5 mbgs and terminated upon encountering a shale/bedrock material. Approximately 100 metric tonnes of impacted soil was removed

from the excavation and stockpiled on-Site for subsequent disposal at a certified waste handling facility, pending the results of the laboratory analysis;

5. To facilitate soil disposal, a “worst case” soil sample (labelled TCLP) was collected from the excavation area and submitted for chemical analysis of metal, benzene and total petroleum hydrocarbons using a Toxicity Characteristic Leaching Procedure (“TCLP”) in accordance with Ontario Regulation 558/00, in order to classify the soil for landfill disposal. The results of the laboratory TCLP analysis indicated that the soils would be classified as a non-hazardous solid waste;

6. Based on the Site specific conditions, the soil quality at the Site was assessed using the Table 3 (non-potable groundwater conditions) Standards for commercial/industrial/institutional land use and coarse grained soils. The standards referenced above are outlined in the “Soil, Groundwater and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act”, MOE, March 9, 2004;

7. The most apparent “worst case” soil samples based on vapour concentrations as well as visual and/or olfactory considerations were recovered from the limits of the excavation and submitted for laboratory chemical analysis. Based on the size of the excavation which had a measured floor area of approximately 28 square metres, three floor samples (FL-5, FL-6 and FL-8) and six wall samples (EW-3, WW-2, SW-4, NW-4, WW-8 and EW-7) were submitted for laboratory analysis.

8. All verification soil samples were collected and submitted to Paracel Laboratories (“Paracel”) located in Ottawa, Ontario in accordance with the Ontario Ministry of the Environment’s (“MOE”) Guidance on Sampling and Analytical Methods for Use at Contaminated Sites in Ontario (1996) and submitted for laboratory analysis of VOC parameters

9. The results of the soil chemical analysis indicated that all of the verification soil samples collected at the Site reported concentrations of all target parameters which satisfied the applicable criteria specified in the applicable Table 3 (non-potable groundwater condition) Standards;

10. In order to address any residual impacted groundwater remaining in the vicinity of the excavation area, two injection galleries were installed on the base of the excavation area, following the collection of the verification soil samples. The injection galleries systems consisted of a 7 meter perforated pipe placed horizontally within the base of the excavation, connected with 90 degree elbows at the ends to solid pipe which was extended vertically to the concrete surface. The horizontal perforated pipe was situated within a bed of clear stone with an approximate thickness of one metre;

11. Following the collection of all verification soil samples from the excavations, all non-impacted material which was stockpiled on-Site was reinstated within the excavations and compacted. Approximately 80 metric tonnes of Granular B, 8.1 metric tonnes of Granular A and 2.4 metric tonnes of clear stone material was imported to the Site and compacted within the excavations in order to restore the excavation areas to the original grade levels. Once the backfill material had been placed and compacted to the appropriate geotechnical standards, the concrete floor slab was reinstated;

12. Upon completion of the reinstatement of the excavation area, Pinchin retained Strata Soil Sampling Inc. to advance one borehole (MW10-1) on October 14, 2010. The borehole was advanced using a Geoprobe 6620 DT direct push drill rig within the central portion of the dry cleaning facility in the immediate vicinity of the dry cleaning equipment. The borehole was advanced to a maximum depth of 4.5 mbgs and terminated upon encountering the underlying shale/bedrock interface. The borehole was instrumented with a monitoring well to enable groundwater monitoring and sampling. The monitoring well MW10-1, which replaced monitoring wells MW05-1 and MW07-1 that had been decommissioned as part of the remedial excavation process, was installed within the dry cleaning facility in order evaluate the environmental condition of the groundwater subsequent to the remedial activities;

13. On October 14, 2010, Pinchin field personnel completed an initial injection program under Certificate of Authorization provided by the MOE. A total of 520 kilograms of sodium permanganate was mixed with 400 litres of clean water and injected into the galleries using a passive gravity injection approach (approx 182 Kg / 140 L was placed into gallery IW10-1A and 338 Kg / 260 L was placed into gallery IW10-2A);

14. In order to determine the effectiveness of the initial injection program, Pinchin returned to the Site on November 19, 2010 to collect groundwater samples from monitoring well MW10-1 (located within the dry cleaning facility) as well as the existing monitoring wells MW05-2 and MW07-2 (which are located immediately adjacent to the dry cleaning facility in the dollarama lunch room). The samples were submitted to Paracel for chemical analysis of VOC parameters;

15. The results of the groundwater sampling program indicated that the groundwater sample collected from the dry cleaning (MW10-1) facility reported concentrations of all VOC parameters which satisfied the Table 3 (non-potable groundwater condition) Standards. However, the groundwater samples collected from the dollarama (MW05-2 and MW07-2) reported concentrations of tetrachloroethylene (“PCE”) at 6.8 ug/L and 6.1 ug/L respectively which marginally exceeded the Table 3 (non-potable groundwater condition) Standard of 5.0 ug/L;

16. As such, Pinchin field personnel returned to the Site on December 13, 2010, to complete a supplemental injection program in order to address the marginal PCE exceedances. A total of 50 kilograms of sodium permanganate was mixed with 200 litres of clean water and injected into the galleries using a passive gravity injection approach (approx 50 L of solution was placed into each of galleries IW10-1A and IW10-2A as well as monitoring well MW05-2 and MW07-2);

17. Pinchin field personnel returned to the Site on February 23, 2011 to collect verification groundwater samples from the monitoring wells which had previously shown exceedances of the applicable standards (MW05-2 and MW07-2). It should be noted that at the time of this sampling event, the groundwater sample collected from MW07-2 still showed signs of oxidant in solution (ie, deep purple in color) and as such, a sample from MW07-2 was not submitted for chemical analysis due to potential interference of the oxidant with the lab instrumentation. The results of the lab analysis indicated that the sample collected from MW05-2 reported concentrations of all target parameters which satisfied the Table 3 (non-potable groundwater condition) Standard; and,

18. Subsequently, Pinchin field personnel returned to the Site on March 24, 2011 to collect a verification groundwater sample from only remaining monitoring well which had previously shown exceedances of the applicable standards (MW07-2). The results of the lab analysis indicated that the sample collected from MW07-2 reported concentrations of all target parameters which satisfied the Table 3 (non-potable groundwater condition)

Standard;

Based on the results of the Remedial Excavation and Verification Soil Sampling Program completed at the Site, including the results of the laboratory analysis, the soils from the area of the Site included as part of this program are deemed to be in compliance with the applicable Table 3 (non-potable groundwater condition) Standards for industrial/commercial/institutional land use and coarse grained soil. In addition, it was reported that the dry cleaning operation has recently switched to environmentally friendly dry cleaning solutions, therefore the potential for the adverse environmental effects to the Site due to the on-going Site operations is not expected. As such, given that the source of the contamination has been eliminated and the potential for recontamination is minimal, no further work is warranted with respect to the soils which underlie the dry cleaning facility.

In terms of the potential for residually impacted groundwater, it should be noted that the concentrations of PCE detected within the groundwater samples collected from within the dry cleaning have decreased from 38 ug/L to 4.6 ug/L and concentrations within the adjacent tenant space have decreased from 6.1 ug/L to 2.3 ug/L as a result of the soil excavation and injection programs. This data infers that the remedial activities completed at the Site have been successful in achieving their remedial objectives of bringing the dry cleaning facility and adjacent tenant space into compliance with the Table 3 (non-potable groundwater condition) Standards.

This Executive Summary is subject to the same standard limitations as contained in the report and must be read in conjunction with the entire report.

1.0 INTRODUCTION

Pinchin Environmental Ltd. (“Pinchin”) was retained through an Authorization to Proceed signed by Mr. Daniel Drimmer of TransGlobe Property Management Services (the “Client”) to supervise a remedial excavation of suspect soils which underlie a current dry cleaning facility and perform a verification soil sampling program at the property referred to as the Herongate Mall located at 1670 Heron Road, Ottawa, Ontario (hereafter referred to as the “Site”). In order to address impacted groundwater, Pinchin was also authorized to complete the installation of an injection gallery and subsequent injection of an oxidizing solution to mitigate any residually impacted groundwater.

1.1 Site Description

The Site is developed with one single-storey multi-tenant commercial building (the “Site Building”), situated in an area of predominant residential and commercial land use. Potable water is supplied to the Site through City of Ottawa municipal services which utilizes the Ottawa River as the potable water source.

As indicated on Figure 1, located in Appendix I, the Site is located on at the intersection of Walkley Road and Heron Road, in Ottawa, Ontario. The Site is situated in an area that predominantly consists of commercial and residential land uses.

2.0 BACKGROUND

The objective of the remedial excavation was to excavate the soils located beneath the dry cleaning equipment which were suspected of being a source of volatile organic compound (“VOC”) impacts which would exceed applicable Ontario Ministry of the Environment “(MOE”) clean-up standards. Removal of the potentially impacted subsurface materials would effectively eliminate any source for future contamination to the groundwater which underlies the Site and verify that the Site is in compliance with applicable MOE assessment standards.

Based on information provided by the Client, it is Pinchin’s understanding that the Client is in the process of completing due diligence at the Site with respect to the potential divestiture of the Site.

2.1 Scope of Work

The scope of work proposed by Pinchin, outlined in the proposal dated October 20, 2010, submitted to the Client included the removal of the concrete floor slab, excavation of all subsurface materials, verification soil sample collection and field interpretation, laboratory analysis, data analysis and report preparation.



3.0 METHODOLOGY

3.1 Excavation Activities

From September 28 through October 15, 2010, Pinchin field personnel were on-Site to supervise the excavation activities completed by Ontario Specialty Contracting (“OSC”). A mini-track driven excavator operated by OSC was used to remove the surficial concrete material and all accessible overburden soils.

Data collected during the excavation operations indicated that the subsurface material at the Site generally consisted of concrete underlain by a sand gravel fill material, successively underlain by native brown silt clay over bedrock, which was observed at a minimum depth of 4.0 meters below ground surface (“mbgs”).

Pinchin field personnel completed a field screening and segregation program using visual, olfactory and organic vapour measurements recorded using a photo-ionization detector (“PID”). The final limits of the excavation were extended until little or no visual or olfactory evidence of environmental impacts were observed.

The non-impacted soil was segregated from the impacted soil as a result of the field screening program and stockpiled on Site for reuse as fill material. The excavation area extended to a maximum depth of 4.0 mbgs and terminated upon encountering a shale/bedrock material. Approximately 100 metric tonnes of impacted soil was removed from the excavation and stockpiled on-Site for subsequent disposal at a certified waste handling facility, pending the results of the laboratory analysis

To facilitate soil disposal, a “worst case” soil sample (labelled TCLP) was collected from the excavation area and submitted for chemical analysis of metal, benzene and total petroleum hydrocarbons using a Toxicity Characteristic Leaching Procedure (“TCLP”) in accordance with Ontario Regulation 558/00, in order to classify the soil for landfill disposal. The results of the laboratory TCLP analysis indicated that the soils would be classified as a non-hazardous solid waste. Photographs of the excavation activities are located in Appendix III.

3.2 Field Screening Samples

Field screening was employed to assess the extent of the potential impacts and aid in segregating suspected impacted material from non-impacted material. Screening samples were placed in Ziploc bags and allowed to equilibrate to ambient temperature. The samples were then screened for total organic vapour (“TOV”) concentrations using the PID, which was calibrated to a known isobutylene standard.

The excavation extended to a maximum depth of approximately 4.0 metres below ground surface (“mbgs”) and terminated without encountering competent bedrock. At a minimum, the soil samples used for field screening were collected at the following intervals:



The floors were divided into a 5 square metre grid pattern; and

Soil samples were collected from each grid unit for field screening of organic vapour concentrations and observations (i.e., location, depth, soil type, grain size, colour and odour).

The limits of the excavation were expanded both vertically and laterally until the results of the field screening program indicated that concentrations of target parameters would satisfy the applicable criteria. The final limits of the excavation are depicted in Figure 2 and a cross section of the remedial excavation is depicted in Figure 3, located in Appendix I.

3.3 Verification Soil Sampling

Once the final limits of the excavation had been established, Pinchin field personnel collected verification soil samples from the excavation area in order to identify remaining soil contaminant levels, if any. The frequency of verification soil samples submitted for laboratory analysis were conducted in accordance with the Ontario Ministry of the Environment’s (“MOE”) Guidance on Sampling and Analytical Methods for Use at Contaminated Sites in Ontario (1996).

The most apparent “worst case” soil samples based on vapour concentrations as well as visual and/or olfactory considerations were recovered from the limits of the excavation and submitted for laboratory chemical analysis. Based on the size of the excavation which had a measured floor area of approximately 28 square metres, three floor samples (FL-5, FL-6 and FL-8) and six wall samples (EW-3, WW-2, SW-4, NW-4, WW-8 and EW-7) were submitted for laboratory analysis.

All verification soil samples were submitted to Paracel Laboratories located in Ottawa, Ontario, an independent and CALA accredited laboratory for chemical analysis of VOC parameters. Approximate locations of verification soil samples collected from the floor of the excavation are depicted in Figure 2 and Figure 3 located in Appendix I.

3.4 QA/QC Protocols

Quality assurance/quality control (QA/QC) protocols were followed during excavation activities and verification soil sampling to ensure that representative samples were obtained. Field protocols that were employed included:

extraction of soil samples from the interior of the sampling device (where possible), rather than from areas in contact with the sampler walls to minimize the chance of cross-contamination;

soil samples collected were placed in laboratory-supplied glass sample jars;

refrigeration of all samples immediately upon collection and maintained en route to the laboratory;



use of nitrile gloves for all sample handling; and

sample collection and handling procedures were performed in accordance with the document “Guidance on Sampling and Analytical Methods for Use at Contaminated Sites in Ontario,” MOE, 1996.

3.5 Applicable Regulatory Standards

The generic soil and groundwater criteria previously provided in the MOE Guideline have been replaced by the Soil, Groundwater and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act (March 9, 2004). For the most part the numerical standards are identical to their predecessor generic criteria, the only difference being the incorporation of the Canada Wide Standards (“CWS”) for PHCs. The current MOE Standards provide advice and information to property owners and consultants to use when assessing the environmental condition of a property, when determining whether or not restoration is required, and in determining the kind of restoration needed to allow continued use or re-use of the Site. The regulation provides three approaches, which may be used for site restoration. These include:

Background Approach: the restoration of the site to the naturally occurring background concentrations;

Generic Approach: the restoration of the site to generically derived soil and groundwater criteria which are protective of human health and of the natural environment; and

Risk Assessment Approach (RA): the restoration of the site to soil and groundwater criteria derived for a specific site, which are protective of human health and of the natural environment but may be less stringent than the generic criteria.

The generic approach involves the application of soil and groundwater quality criteria, which have been developed to provide protection against potential adverse effects to human health, ecological health, and the natural environment. The guideline provides four sets of generic criteria for 118 parameters, including volatile organic compounds and petroleum hydrocarbons. These criteria have been developed using a risk-based approach. The application of the appropriate criteria is dependent upon several site-specific conditions including:

the existing/proposed land use;

the existing/potential groundwater use;

soil depth; and

soil texture.

In many instances, despite the final restoration approach adopted, the generic criteria developed by the MOE serve as the necessary benchmarks for evaluating the need for additional investigations and/or the implementation of a risk management or remedial strategy at the Site.



The Site is a commercial property located in Ottawa, Ontario. It is Pinchin’s understanding that potable water for the Site and surrounding area is supplied by City of Ottawa municipal services which utilizes the Ottawa River as the water source. The Site is situated in an area that predominantly consists of residential and commercial land uses. Representative soil sample were submitted for grain size distribution and pH analysis, and were reported as coarse grained and having a pH within the applicable range for the use of the generic approach.

Based on the Site specific information presented above, the soil quality at the Site was assessed using Table 3 (non-potable groundwater conditions) Standards for industrial/commercial/institutional land use and coarse grained soils. The standards referenced above are outlined in the “Soil, Groundwater and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act”, MOE, March 9, 2004.

4.0 VERIFICATION SOIL SAMPLING RESULTS

4.1 Site Geology

Data collected during the excavation operation indicated that the subsurface material at the Site generally consisted of concrete underlain by a sandy gravel fill material, successively underlain by native brown silt clay over bedrock. The excavation extended to a maximum depth of 4.0 mbgs and terminated without encountering bedrock. The excavation extended until no visual or olfactory evidence of environmental impacts were observed.

4.2 Analytical Results

4.2.1 Contaminated Soil Disposal Analysis

One “worst case” soil sample was collected from the stockpiled soil (labelled ‘TCLP’), and submitted to the laboratory for chemical analysis of leachable metal, benzene and total petroleum hydrocarbon parameters using a Toxicity Characteristic Leaching Procedure (“TCLP”) in accordance with Ontario Regulation 558/00, in order to classify the soil for landfill disposal.

The results of the laboratory analysis of the “worst case” soil sample which was submitted for chemical analysis of leachable metals and leachable VOC parameters using a TCLP, is summarized in Table 1, and can be found in Appendix II. The laboratory certificates of analyses are provided in Appendix III.

The results of the TCLP analyses indicated that the impacted soil removed from the Site was classified as non-hazardous solid waste.



4.2.2 Verification Soil Sample Analysis

The results of the laboratory analysis completed on the verification soil samples submitted for chemical analysis of VOC parameters along with their applicable standards are summarized in Table 2, and can be found in Appendix II. The laboratory certificates of analysis are located in Appendix IV.

The results of the laboratory analysis indicated that the verification soil samples submitted for chemical analysis reported concentrations of all targeted parameters which satisfied applicable criteria specified in the Table 3 (non-potable groundwater conditions) Standards.

4.3 Earthwork Volumes

The non-impacted soil was segregated from the impacted soil as a result of the field screening program and stockpiled on Site for reuse as fill material. Approximately 100 metric tonnes of impacted soil was segregated from the excavation and held on-Site for subsequent disposal at an approved landfill and certified waste handling facility.

Following the collection of all verification soil samples from the excavations, all non-impacted material which was stockpiled on-Site was reinstated within the excavations and compacted. Approximately 80 metric tonnes of Granular B, 8.1 metric tonnes of Granular A and 2.4 metric tonnes of clear stone material was imported to the Site and compacted within the excavations in order to restore the excavation areas to the original grade levels.

4.4 Groundwater Monitoring Well Reinstatement

Upon completion of the reinstatement of the excavation area, Pinchin retained Strata Soil Sampling Inc. to advance one borehole (MW10-1) on October 14, 2010. The borehole was advanced using a Geoprobe 6620 DT direct push drill rig within the central portion of the dry cleaning facility in the immediate vicinity of the dry cleaning equipment. The borehole was advanced to a maximum depth of 4.5 mbgs and terminated upon encountering the underlying shale/bedrock interface. The borehole was instrumented with a monitoring well to enable groundwater monitoring and sampling. The monitoring well MW10-1, which replaced monitoring wells MW05-1 and MW07-1 that had been decommissioned as part of the remedial excavation process, was installed within the dry cleaning facility in order evaluate the environmental condition of the groundwater subsequent to the remedial activities.

The Screen was sealed using threaded caps and the riser was sealed with a lockable J-plug cap. Silica sand was placed around and above the screened interval to form a filter pack around the well screen. A layer of bentonite was placed above the silica sand and was extended to the ground surface. A protective flush-mount cover was installed over the riser pipe at the ground surface and cemented in place. The location of the monitoring well is shown on Figure 2 of Appendix I.



5.0 IN-SITU CHEMICAL OXIDATION PROGRAM

In order to address any residual impacted groundwater remaining in the vicinity of the excavation area, two injection galleries were installed on the base of the excavation area, following the collection of the verification soil samples. The injection gallery system consisted of a 7 meter length of perforated pipe placed horizontally within the base of the excavation, connected with 90 degree elbows at the ends to solid pipe which was extended vertically to the concrete surface. The horizontal perforated pipe was situated within a bed of clear stone with an approximate thickness of one metre.

Briefly, sodium permanganate crystals were dissolved in water and injected under passive gravity influence into the contaminated aquifer. Sodium permanganate is a relatively inexpensive product and the one most commonly used for remediation work of this nature. At some sites PCE has been reduced more than 97% in less than 10 days. It has been Pinchin’s experience that for many contaminated properties, potassium permanganate is the preferred technology for the remediation of dry cleaning sites. Permanganate chemically oxidizes PCE, TCE, DCE and VC to produce carbon dioxide, manganese oxide and potassium, chloride and hydrogen ions (all of which are non-harmful constituents). Permanganate solutions are purple and this colour can be used to track the distribution of the oxidant. When the permanganate reacts with the contaminants of concern (i.e., PCE in this case) the manganese oxide that forms is a dark brown colour.

5.1 Initial Injection Event

On October 14, 2010, Pinchin field personnel returned to the Site with OSC to complete an initial injection program under Certificate of Authorization provided by the MOE. A total of 520 kilograms of sodium permanganate was mixed with 400 litres of clean water and injected into the galleries using a passive gravity injection approach (approx 182 Kg / 140 L was placed into gallery IW10-1A and 338 Kg / 260 L was placed into gallery IW10-2A).

5.2 Post-Injection Groundwater Sampling Program

In order to determine the effectiveness of the initial injection program, Pinchin returned to the Site on November 19, 2010 to collect groundwater samples from monitoring well MW10-1 (located within the dry cleaning facility) as well as the existing monitoring wells MW05-2 and MW07-2 (which are located immediately adjacent to the dry cleaning facility in the dollarama lunch room). The groundwater samples were submitted to Paracel for chemical analysis of VOC parameters.

The results of the groundwater sampling program indicated that the groundwater sample collected from the dry cleaning facility (MW10-1) reported concentrations of all VOC parameters which satisfied the Table 3 (non-potable groundwater condition) Standards. The groundwater samples collected from the dollarama (MW05-2 and MW07-2) displayed



decreasing concentration trends for tetrachloroethylene (“PCE”) at 6.8 ug/L and 6.1 ug/L respectively which marginally exceeded the Table 3 (non-potable groundwater condition) Standard of 5.0 ug/L.

The results of the laboratory analysis completed on the post-remediation groundwater verification samples that were submitted for chemical analysis of VOC parameters along with their applicable standards are summarized in Table 3, and can be found in Appendix II. The laboratory certificates of analysis are located in Appendix IV.

Pinchin has included analytical data from groundwater sampling events completed prior and subsequent to this remedial program for comparison purposes. It should be noted that overall, the groundwater samples collected subsequent to the remedial program including the initial injection event, have demonstrated a significant reduction in VOC parameters (specifically PCE) when compared to the data collected prior to the remediation program. This infers that the remedial excavation and oxidation injection program were successful in reaching their remedial objectives for the dry cleaning facility.

5.3 Supplemental Injection Program

In order to address the low level impacted groundwater detected in MW05-2 and MW07-2, Pinchin field personnel returned to the Site on December 13, 2010, to complete a supplemental injection program in order to address the marginal PCE exceedances. A total of 50 kilograms of sodium permanganate was mixed with 200 litres of clean water and injected into the galleries using a passive gravity injection approach (approx 50 L of solution was placed into each of galleries IW10-1A and IW10-2A as well as monitoring well MW05-2 and MW07-2).

Pinchin field personnel returned to the Site on February 23, 2011 to collect verification groundwater samples from the monitoring wells which had previously shown exceedances of the applicable standards (MW05-2 and MW07-2). It should be noted that at the time of this sampling event, the groundwater sample collected from MW07-2 still showed signs of oxidant in solution (ie, deep purple in color) and as such, a sample from MW07-2 was not submitted for chemical analysis due to potential interference of the oxidant with the lab instrumentation. The results of the lab analysis indicated that the groundwater verification sample collected from MW05-2 reported concentrations of all target parameters which satisfied the Table 3 (non-

potable groundwater condition) Standard.

Subsequently, Pinchin field personnel returned to the Site on March 24, 2011 to collect a verification groundwater sample from only remaining monitoring well which had previously shown exceedances of the applicable standards (MW07-2). The results of the lab analysis indicated that the sample collected from MW07-2 reported concentrations of all target parameters which satisfied the Table 3 (non-potable groundwater condition) Standard.



6.0 CONCLUSIONS

The following is a summary of activities and results of this comprehensive remedial program conducted at the Site:

1. From September 28 through October 15, 2010, Pinchin field personnel were on-Site to supervise the excavation activities completed by Ontario Specialty Contracting (“OSC”). A mini-track driven excavator operated by OSC was used to remove the surficial concrete material and all accessible overburden soils;

2. Data collected during the excavation operations indicated that the subsurface material at the Site generally consisted of concrete underlain by a sand gravel fill material, successively underlain by native brown silt clay over bedrock, which was observed at a minimum depth of 5.5 meters below ground surface (“mbgs”);

The excavation area extended to a maximum depth of 4.5 mbgs and terminated upon encountering a shale/bedrock material. Approximately 100 metric tonnes of impacted soil was removed from the excavation and stockpiled on-Site for subsequent disposal at a certified waste handling facility, pending the results of the laboratory analysis;

5. To facilitate soil disposal, a “worst case” soil sample (labelled TCLP) was collected from the excavation area and submitted for chemical analysis of metal, benzene and total petroleum hydrocarbons using a Toxicity Characteristic Leaching Procedure (“TCLP”) in accordance with Ontario Regulation 558/00, in order to classify the soil for landfill disposal. The results of the laboratory TCLP analysis indicated that the soils would be classified as a non-hazardous solid waste;

6. Based on the Site specific conditions, the soil quality at the Site was assessed using the Table 3 (non-potable groundwater conditions) Standards for commercial/industrial/institutional land use and coarse grained soils. The standards referenced above are outlined in the “Soil, Groundwater and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act”, MOE, March 9, 2004;

7. The most apparent “worst case” soil samples based on vapour concentrations as well as visual and/or olfactory considerations were recovered from the limits of the excavation and submitted for laboratory chemical analysis. Based on the size of the excavation which had a measured floor area of approximately 28 square metres, three floor samples (FL-5, FL-6 and FL-8) and six wall samples (EW-3, WW-2, SW-4, NW-4, WW-8 and EW-7) were submitted for laboratory analysis.

8. All verification soil samples were collected and submitted to Paracel Laboratories (“Paracel”) located in Ottawa, Ontario in accordance with the Ontario Ministry of the Environment’s (“MOE”) Guidance on Sampling and Analytical Methods for Use at



Contaminated Sites in Ontario (1996) and submitted for laboratory analysis of VOC parameters

9. The results of the soil chemical analysis indicated that all of the verification soil samples collected at the Site reported concentrations of all target parameters which satisfied the applicable criteria specified in the applicable Table 3 (non-potable groundwater condition) Standards;

10. In order to address any residual impacted groundwater remaining in the vicinity of the excavation area, two injection galleries were installed on the base of the excavation area, following the collection of the verification soil samples. The injection galleries systems consisted of a 7 meter perforated pipe placed horizontally within the base of the excavation, connected with 90 degree elbows at the ends to solid pipe which was extended vertically to the concrete surface. The horizontal perforated pipe was situated within a bed of clear stone with an approximate thickness of one metre;

11. Following the collection of all verification soil samples from the excavations, all non-impacted material which was stockpiled on-Site was reinstated within the excavations and compacted. Approximately 80 metric tonnes of Granular B, 8.1 metric tonnes of Granular A and 2.4 metric tonnes of clear stone material was imported to the Site and compacted within the excavations in order to restore the excavation areas to the original grade levels. Once the backfill material had been placed and compacted to the appropriate geotechnical standards, the concrete floor slab was reinstated;

12. Upon completion of the reinstatement of the excavation area, Pinchin retained Strata Soil Sampling Inc. to advance one borehole (MW10-1) on October 14, 2010. The borehole was advanced using a Geoprobe 6620 DT direct push drill rig within the central portion of the dry cleaning facility in the immediate vicinity of the dry cleaning equipment. The borehole was advanced to a maximum depth of 4.5 mbgs and terminated upon encountering the underlying shale/bedrock interface. The borehole was instrumented with a monitoring well to enable groundwater monitoring and sampling. The monitoring well MW10-1, which replaced monitoring wells MW05-1 and MW07-1 that had been decommissioned as part of the remedial excavation process, was installed within the dry cleaning facility in order evaluate the environmental condition of the groundwater subsequent to the remedial activities;

13. On October 14, 2010, Pinchin field personnel completed an initial injection program under Certificate of Authorization provided by the MOE. A total of 520 kilograms of sodium permanganate was mixed with 400 litres of clean water and injected into the galleries using a passive gravity injection approach (approx 182 Kg / 140 L was placed into gallery IW10-1A and 338 Kg / 260 L was placed into gallery IW10-2A);

14. In order to determine the effectiveness of the initial injection program, Pinchin returned to the Site on November 19, 2010 to collect groundwater samples from monitoring well



MW10-1 (located within the dry cleaning facility) as well as the existing monitoring wells MW05-2 and MW07-2 (which are located immediately adjacent to the dry cleaning facility in the dollarama lunch room). The samples were submitted to Paracel for chemical analysis of VOC parameters;

15. The results of the groundwater sampling program indicated that the groundwater sample collected from the dry cleaning (MW10-1) facility reported concentrations of all VOC parameters which satisfied the Table 3 (non-potable groundwater condition) Standards. However, the groundwater samples collected from the dollarama (MW05-2 and MW07-2) reported concentrations of tetrachloroethylene (“PCE”) at 6.8 ug/L and 6.1 ug/L respectively which marginally exceeded the Table 3 (non-potable groundwater condition) Standard of 5.0 ug/L;

16. As such, Pinchin field personnel returned to the Site on December 13, 2010, to complete a supplemental injection program in order to address the marginal PCE exceedances. A total of 50 kilograms of sodium permanganate was mixed with 200 litres of clean water and injected into the galleries using a passive gravity injection approach (approx 50 L of solution was placed into each of galleries IW10-1A and IW10-2A as well as monitoring well MW05-2 and MW07-2);

17. Pinchin field personnel returned to the Site on February 23, 2011 to collect verification groundwater samples from the monitoring wells which had previously shown exceedances of the applicable standards (MW05-2 and MW07-2). It should be noted that at the time of this sampling event, the groundwater sample collected from MW07-2 still showed signs of oxidant in solution (ie, deep purple in color) and as such, a sample from MW07-2 was not submitted for chemical analysis due to potential interference of the oxidant with the lab instrumentation. The results of the lab analysis indicated that the sample collected from MW05-2 reported concentrations of all target parameters which satisfied the Table 3 (non-potable groundwater condition) Standard; and,

18. Subsequently, Pinchin field personnel returned to the Site on March 24, 2011 to collect a verification groundwater sample from only remaining monitoring well which had previously shown exceedances of the applicable standards (MW07-2). The results of the lab analysis indicated that the sample collected from MW07-2 reported concentrations of all target parameters which satisfied the Table 3 (non-potable groundwater condition)

Standard;



7.0 RECOMMENDATIONS

Based on the results of the Remedial Excavation and Verification Soil Sampling Program completed at the Site, including the results of the laboratory analysis, the soils from the area of the Site included as part of this program are deemed to be in compliance with the applicable Table 3 (non-potable groundwater condition) Standards for industrial/commercial/institutional land use and coarse grained soil. In addition, it was reported that the dry cleaning operation has recently switched to environmentally friendly dry cleaning solutions, therefore the potential for the adverse environmental effects to the Site due to the on-going Site operations is not expected. As such, given that the source of the contamination has been eliminated and the potential for recontamination is minimal, no further work is warranted with respect to the soils which underlie the dry cleaning facility.

In terms of the potential for residually impacted groundwater, it should be noted that the concentrations of PCE detected within the groundwater samples collected from within the dry cleaning have decreased from 38 ug/L to 4.6 ug/L and concentrations within the adjacent tenant space have decreased from 6.1 ug/L to 2.3 ug/L as a result of the soil excavation and injection programs. This data infers that the remedial activities completed at the Site have been successful in achieving their remedial objectives of bringing the dry cleaning facility and adjacent tenant space into compliance with the Table 3 (non-potable groundwater condition) Standards.

8.0 DISCLAIMER

This Remedial Excavation and Verification Soil Sampling Program were performed in order to mitigate the recognized environmental conditions which were detected beneath the dry cleaning facility at 1670 Heron Road (“Site”). The term ‘recognized environmental condition’ means the presence or likely presence of any hazardous substance on a property under conditions that indicate an existing release, past release, or a material threat of a release of a hazardous substance into structures on the property or into the ground, groundwater, or surface water of the property.

Conclusions derived are specific to the immediate area of study and cannot be extrapolated extensively away from sample locations. Samples have been analyzed for a limited number of contaminants that are expected to be present at the Site, and the absence of information relating to a specific contaminant does not indicate that it is not present.

No environmental remedial excavation can wholly eliminate uncertainty regarding the potential for recognized environmental conditions on the property. Performance of this remedial excavation to the standards established by Pinchin is intended to remediate the area outlined in the scope of work, but does not eliminate uncertainty regarding the potential for recognized environmental conditions on the property, and recognizes reasonable limits on time and cost.



This Remedial Excavation and Verification Soil Sampling Program were performed in general compliance with currently acceptable practices for environmental site investigations, and specific client requests, as applicable to this Site. This report was prepared for the exclusive use of TransGlobe Property Management Services, subject to the conditions and limitations contained within the duly authorized workplan.
