EXECUTIVE SUMMARY

Morrison Hershfield Ltd. (MH) was retained by the Town of Hawkesbury (the Client), to perform a Phase II Environmental Site Assessment (ESA) for three (3) property parcels at the eastern end of the Chenail Boulevard (“the site”).

A Phase I ESA was not completed for the site prior to this Phase II ESA, but environmental information was obtained from four (4) background reports supplied by the client. Key findings from these reports included the presence of a former railway line that ran across the site, significant infilling activities with suspected material from an industrial site, and use of the site and surrounding area for bulk fuel storage from the 1930’s to 1992. Based on this review, the contaminants of concern (COCs) were identified as metals, Polycyclic Aromatic Hydrocarbons (PAH), Petroleum Hydrocarbons (PHC), and Volatile Organic Compounds (VOC).

The environmental field program was performed in three (3) stages, building on the results from the prior stage. A total of fourteen (14) boreholes were drilled, all of which were completed as monitoring wells. Soil and groundwater samples were collected and analyzed for the COCs. Based on the site setting, MECP Table 3 standards for Residential/Parkland/Institutional Property Use were selected to assess the soil and groundwater quality at the site.

Fill on the site contains various debris including coal and slag, and contained metals and PAHs at concentrations above the applicable standards. Various petroleum-related contaminants were detected in soil, both at the northern edge of the Chenail Boulevard right-of-way, and south of the right-of-way, at the location of a former fuel oil depot.

The petroleum-related contaminants at the northern edge of the Chenail Boulevard right-of- way are thought to be the source of a plume of PHC F3/F4 and PAH in groundwater. This plume appears to extend slightly onto adjacent private properties.

The petroleum-related contaminants to the south of Chenail Boulevard, at the former fuel depot, are thought to be the source of a plume of PHC F2 in groundwater that appears fully contained on Town of Hawkesbury property.

A preliminary risk evaluation of the groundwater plumes suggests that, in their current state, these plumes are not resulting in any unacceptable risk to on-site receptors. Immediate remedial action is not required.

An additional round of groundwater sampling is recommended, along with a targeted additional investigation of shallow fill. The fact that the groundwater contamination appears to extend to adjacent private properties should be disclosed to the MECP.

1. INTRODUCTION

Morrison Hershfield Ltd. (MH) was retained by the Town of Hawkesbury (the Client), to perform a Phase II Environmental Site Assessment (ESA) for three (3) property parcels at the eastern end of the Chenail Boulevard.

This Phase II ESA was initiated in response to a Phase II ESA completed by Lascelles & Associates for the adjacent property to the northeast, described as Lots 1 and 17 – Registered Plan M-20, Part of Block 21 – Registered Plan 46M-67, Belle Rive Crescent, Hawkesbury, Ontario.

The objective of this Phase II ESA was to investigate the soil and groundwater conditions, to determine if the fuel oil depot that was historically present at these properties has impacted the subsurface and, to attempt to delineate the plume, if groundwater contamination is encountered.

This report has been prepared following the principles of the Canadian Standards Association Z769-00 – Phase II Environmental Site Assessment standard and in accordance with generally accepted professional practices. This Phase II ESA is not intended to support the filing of a Record of Site Condition (RSC) under Part XV.1 of the Environmental Protection Act.

1.1 Site Description

Four (4) distinct property parcels (labeled Parcel 1, 2, 3 and 4 for convenience) were included in this Phase II ESA investigation. This includes the three (3) parcels that form the eastern end of the Chenail Blvd. An additional parcel, which makes up Belle Rive Street, was also included for potential delineation purposes. These parcels are all owned by the Town of Hawkesbury and additional property details are summarized in Table 1 below.

registrations. Title records or an updated plan of survey are required to confirm the accuracy of property information.

The property index map downloaded from the Ontario Land Registration System is shown in Appendix A This map shows all four (4) property parcels, with parcel 2 (PIN 54169-0153) and parcel 3 (PIN 54169-0167) highlighted on the map. The property parcels are also shown on the site plan on Figure 1 in Appendix B. Collectively, these property parcels will be referred to as “the site” throughout this report.

1.2 Background Environmental Information

A Phase I ESA was not completed for the site prior to this Phase II ESA. That said, environmental information was obtained from the following reports:

 Conestoga-Rovers & Associates, 1992. Phase I and II Environmental Audit, Town of Hawkesbury, Ontario. (Report 1)

 Conestoga-Rovers & Associates Limited, 1992. Remediation of Parts 4 and 8, Town of Hawkesbury, Ontario. (Report 2)

 Lascelles Engineering & Associates, 2017. Phase I – Environmental Site Assessment Lots 1 and 17 – Registered Plan M-20, Part of Block 21 – Registered Plan 46M-67, Belle Rive Street, Hawkesbury, Ontario. (Report 3)

 Lascelles Engineering & Associates, 2017. Phase II – Environmental Site Assessment Lots 1 and 17 – Registered Plan M-20, Part of Block 21 – Registered Plan 46M-67, Belle Rive Crescent, Hawkesbury, Ontario. (Report 4)

Key findings from these reports are summarized below and presented on Figure 2 in Appendix B:

Report 1

A Phase I and II environmental audit was performed for eight (8) parcels of land, adjacent to the Ottawa River (identified as parts 2 to 10 of Registered Plan 46R-4909). This audit was performed to support a land exchange between the Town of Hawkesbury and a developer. As part of this exchange, the Town of Hawkesbury received six (6) parcels, two (2) of which are located within the site and became the present day Chenail Boulevard.

The Phase I portion of this audit indicated that a spur line of the former Grand Trunk Railway was located in the vicinity of the site, as early as 1923. This spur line serviced the Hawkesbury Mills Lumber Company to the east and was converted to a Canadian National railway line by 1960.

A 1960 fire insurance plan indicated that portions of the site and the surrounding area were used for bulk fuel storage facilities by various oil companies. These facilities were originally established in the 1930’s. The site specifically, was occupied by the former Cities Service Oil Co. Ltd. facility which contained an oil and grease storage warehouse with four (4) vertical above ground oil tanks. It was noted that the tanks had been removed at the time of this report (1992). The site was also occupied by the former Rene Bertrand fuel oil depot,

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 3

containing four (4) above ground storage tanks (AST) on steel trestles and an oil storage warehouse. At the time of this report (1992), this property was being leased to Esso Petroleum, from the Town of Hawkesbury and operated as the Pilon Esso Terminal. One (1) large vertical AST, three (3) smaller vertical ASTs and a pump terminal were reportedly added to this property when it was occupied by Esso Petroleum.

The deposit of significant quantities of fill was also noted in the area. Adjacent properties to the north/northwest of the site were previously an inlet of the Ottawa River (i.e. a water lot). This water lot was filled in the 1970’s. The quality of the fill material is unknown but it was rumored that portions of the fill consisted of material from a neighboring pulp and paper mill.

The Phase II component of this audit involved excavating 11 test pits (TP1-91 to TP11-91) across the eight (8) property parcels. Select soil samples were analyzed for benzene, toluene, ethylbenzene and xylenes (BTEX), total oil and grease and total metals. Three (3) test pits (TP2-91, TP10-91, TP11-91) had total petroleum hydrocarbons present above applicable criteria. Two (2) of these test pits were located in the site, near the Pilon Esso Terminal. The other was located east of the northern portion of Race Street.

It was noted that Esso Petroleum Ltd. was planning on remediating the impacted property in spring 1992.

Report 2

This report was initiated based on the hydrocarbon/fuel oil impacts that were found in the test pit (TP2-91) located on property parcel 8 during the Phase II investigation described above in Report 1. This corresponds to the land immediately east of the northern portion of Race Street. This reports documents the additional delineation that was performed.

Eight (8) test pits (TP12-92 to TP19-92) were excavated in the vicinity of the impacted test pit (TP2-91), with select soil samples submitted for analysis of BTEX, gasoline, fuel oil and total petroleum hydrocarbons. This report delineated the horizontal extent of hydrocarbon impacted soil at this location.

Report 3

This Phase I ESA was completed for the vacant land at the end of Belle Rive Crescent, located north/east of the site (Lots 1 and 17 – Registered Plan M-20, Part of Block 21 – Registered Plan 46M-67).

Much of the information presented in Report 1 was reiterated in this Phase I ESA. Additional findings included the presence of an automobile dealer with three underground storage tanks (USTs) between John Street and Richer Street, and a bus terminal with 4 USTs, located across from the auto dealer on the east side of John Street. This information was shown on a fire insurance plan from 1960.

It was also indicated that, according to a Town of Hawkesbury environmental planner, a soil remediation program was carried out during the construction of the Chenail Boulevard. No reports were available however to document this work, so the extent of remediation is unknown.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 4

A Phase I/II ESA for the Perley Bridge Land Acquisition, completed by Conestoga-Rovers & Associates (CRA) in 1996 was discussed in this report. A figure from the CRA report showed that the previously mentioned automobile dealer was converted to an Ultramar branded retail fuel outlet, with the three (3) USTs still present. A Petro Canada retail fuel outlet was also shown on the east side of John Street, with four (4) USTs present. It was noted in the summary of this report, that hydrocarbon impacted soil (total oil and grease concentration of 15,500 ppm) was present within the limits of the present day Chenail Boulevard.

Report 4

This Phase II ESA was initiated based on the findings in Report 3. Field work included digging eight (8) test pits across the subject property, to depths ranging from 2.5 to 3.6 m. Monitoring wells were installed in three (3) of the test pits prior to backfilling.

Six (6) soil samples were collected from the test pits and submitted for lab analysis. This included three (3) samples for analysis of BTEX and petroleum hydrocarbons (PHCs) and three (3) samples for analysis of metals. All soil samples met the applicable MECP site condition standards.

Groundwater samples were collected from two (2) of the three (3) wells. These samples were submitted for analysis for BTEX, PHC and metals. Toluene, PHC F3 and PHC F4 were detected in the groundwater samples, with PHC F3 exceeding the applicable standards. The wells were resampled a week later and toluene and PHC F3 were still detected in these water samples but all concentrations met that applicable standards.

Based on these findings it was suggested that the subject property may have been on the leading edge of a PHC plume. 1.3 Potentially Contaminating Activities

As outlined in section 1.2, a number of potentially contaminating activities (PCA) have occurred at the site and surrounding properties. Using the list of PCAs outlined in Table 2 of Schedule D of O.Reg. 153/04, it is believed the following PCAs could have impacted the site:

1. Gasoline and Associated Products Storage in Fixed Tanks. Numerous ASTs associated with oil companies and USTs associated with retail fuel outlets and auto dealers were located in and around the site. The specific petroleum products stored in these tanks is unknown, but they likely contained one of the following: gasoline, diesel, light fuel oil (i.e. heating oil) and possibly heavy fuel oil at the oil depots.

2. Importation of Fill Material of Unknown Quality

3. Rail Yards, Tracks and Spurs

The contaminants of concern (COC) and potentially impacted environmentally media, associated with each PCA are summarized in Table 2 below.

Potentially PCA Contaminants of Potential Concern Impacted Media Metals, Gasoline and Associated Polycyclic Aromatic Hydrocarbons (PAH), Subsurface Soil Products Storage in Fixed Petroleum Hydrocarbons (PHC), and Groundwater Tanks Volatile Organic Compounds (VOC) Importation of Fill Material Surface Soil (0 – Metals, PAH of Unknown Quality 1.5m) Rail Yards, Tracks and Surface Soil (0 – Metals, PAH Spurs 1.5m)

These PCAs were the principal points of investigation for this Phase II ESA.

1.4 Scope of Work

The scope of work for this Phase II ESA included the following:

 Performing a subsurface investigation consisting of borehole drilling, soil sampling, monitoring well installations, and groundwater monitoring/sampling.

 Conducting chemical analysis of soil and groundwater samples for the identified contaminants of concern.

 Delineating any groundwater plume, if encountered and assessing the impacts of the PCAs on the site.

 Summarizing and interpreting the collected data and preparing a report to document the findings.

2. METHODS

2.1 Borehole Drilling

The boreholes were advanced by either a CME-55LC track mounted drill rig or CME 75 truck mount drill rig. A power auger drilling method with 8 in. outside diameter (OD) hollow stem augers was used for all boreholes.

A total of 14 boreholes were drilled as part of this Phase II ESA. A summary of the completed borehole and drilling depths is provided below:

2.2 Soil Sampling

Continuous soil samples were collected using a 0.61 m (2 ft.) long, 50 mm (2 in.) OD split spoon sampler. The sampler was driven into the soil with blows from a 63.5 kg hammer dropped from a height of 760 mm using an automatic hammer drop system.

Split spoons were cleaned between samples with a brush in an aqueous solution of AlconoxTM detergent and were rinsed with an organic desorbing agent (methanol) and with deionized water before being reused.

The retrieved soil samples were immediately inspected in the split spoons for field evidence of contamination and then transferred to polyethylene bags for sampling and headspace organic vapour screening. Nitrile gloves were worn by MH field staff at all times during collection and handling of soil samples, and were changed for each sample in order to minimize the potential for cross contamination.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 7

2.3 Field Screening Measurements

Field screening was performed using an RKI Eagle II gas monitor, equipped with photoionization detector (PID) and combustible gas indicator (CGI) sensors and methane elimination mode turned on. Prior to use in the field, the PID was calibrated using an isobutylene standard of 100 ppm, while the CGI was calibrated using a hexane standard of 400 ppm.

The polyethylene bags used for vapour screening were filled halfway with soil and allowed to equilibrate for several minutes before conducting the headspace vapour readings. During reading events, the probe-tip of the gas monitor was used to puncture the sealed polyethylene bag and the peak PID and CGI readings were recorded after 15 seconds of measurement.

Based on field evidence of contamination and/or headspace vapour readings, the most contaminated samples and a representative set of samples from various depths were placed in laboratory supplied jars and vials. The filled jars and vials for each soil sample included one (1) 150 mL and one (1) 250 mL glass jars with Teflon-lined lids, and two (2) 40 mL glass vials with methanol preservative. The soil that was placed in the 40 mL glass vials was collected in 5 g samples using dedicated Terra Core TM samplers. The samples were then placed in ice-filled coolers for storage, prior to delivery to the lab.

Following sample collection, a minimum of one (1) soil sample from each borehole was selected for laboratory analysis of one (1) or more of the identified contaminants of concern (COC).

2.4 Monitoring Well Installation

Monitoring wells were installed in all 14 boreholes advanced as part of this investigation. The monitoring wells were constructed using 50 mm diameter, schedule 40 polyvinyl chloride (PVC) riser pipes and slotted screens. The majority of wells contained a 3.05 m long slotted screen with 0.25 mm slot spacing and solid riser pipes which extended to ground surface, at minimum. The monitoring wells were installed in accordance with the requirements of R.R.O. 1990, Reg. 903 under the supervision of MH field staff. The top of each riser pipe was sealed with a slip cap and covered with either a flush-mount protective casing or a stick-up monument casing. Silica sand #2 was used to fill the borehole annulus around the screened portion of the monitoring well and extended at least 30 cm above the top of the screen. Sodium bentonite HOLEPLUG® (3/8” grade) was placed to seal the remaining annular space surrounding the PVC riser pipes, up to ground surface.

2.5 Groundwater Monitoring and Sampling

Groundwater monitoring was performed on July 28th, 2020 and involved collecting static water levels and determining the presence (and if applicable, thickness) of non-aqueous phase liquid (NAPL) from all installed monitoring wells at the site. Groundwater monitoring was performed using a Solinst Model 122 interface probe, which was used to measure the depth to water in meters below the top of the riser pipe (mBTOP) and to confirm the presence/absence of NAPL in each monitoring well. Vapour readings were also taken from each monitoring well using an RKI Eagle II. These readings were taken immediately after

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 8

removing the J-plug from the well and were collected by inserting the probe a few inches below the top of the riser pipe.

Monitoring well purging and sampling was performed using dedicated low-density polyethylene (LDPE) tubing equipped with an inertial foot valve. Groundwater samples were collected after three (3) well volumes were purged from the well. Groundwater samples collected for metals analysis were field filtered at the time of sample collection using in-line 0.45 µm filters. The groundwater samples were collected in laboratory supplied bottles and vials, filled to the laboratory recommended volumes and subsequently placed in an ice filled cooler for transportation to the lab.

2.6 Laboratory Analysis of Soil and Groundwater

All soil and groundwater samples were submitted under chain of custody documentation to ALS Environmental (ALS) of Ottawa, Ontario. ALS is a Canadian Association for Laboratory Accreditation (CALA) accredited laboratory for the analyses performed.

All samples were received and analyzed within the sample holding times outlined in the Protocol for Analytical Methods Used in the Assessment of Properties under Part XV.1 of the Environmental Protection Act.

2.7 Residue Management

Soil cuttings and contaminated purge water generated during the investigation were temporarily stored on-site in UN-approved 45 gallon metal drums.

Soil was collected off of the auger flights following the drilling of each borehole in order to form composite soil samples for waste characterization analysis. This involved submitting the composite soil samples for toxicity characteristic leaching procedure (TCLP) analysis to determine waste management requirements.

2.8 Elevation Surveying

Elevations of the ground surface and the top of the riser pipe for each monitoring well were collected using a Topocon RL-H4C Laser level. The elevations were surveyed using a specified site benchmark with elevation provided in meters above sea level (mASL).

The selected site benchmark was the top of the spindle on the fire hydrant located at the Belle Rive Crescent cul-de-sac. According to a grade and drainage plan supplied by the Town of Hawkesbury, this benchmark has an elevation of 45.70 mASL.

2.9 Quality Assurance/Quality Control

Quality assurance and quality control (QA/QC) measures were employed during the field program and included the following:

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 9

 Non-dedicated sampling equipment was decontaminated between sampling events by cleaning the equipment in an aqueous solution of AlconoxTM detergent and rinsing it with methanol and deionized water before reuse.

 A fresh pair of nitrile gloves were worn by field staff at all times during sample collection and handling to minimize the potential for cross contamination.

 Soil, groundwater and sediment samples were collected in pre-cleaned, laboratory supplied bottles, jars and vials, with preservation (as necessary).

 Prior to delivery to the lab, samples were handled and stored in accordance with the requirements outlined in the MECP document “Protocol for Analytical Methods Used in the Assessment of Properties under Part XV.1 of the Environmental Protection Act”, March 9, 2004 (amended as of July 1, 2011).

In addition to these measures, field QC samples were collected in order to determine the precision of the analytical methods and assess the error associated with sample heterogeneity. The field QC samples included blind duplicate samples to evaluate analytical precision, field precision and sample homogeneity.

Precision between duplicate samples is measured using the Relative Percent Difference (RPD) method. The RPD is calculated as follows:

|퐶 − 퐶 | 푅푃퐷 = 푠 푑 푥 100 (퐶푠 + 퐶푑)/2

where 퐶푠 the concentration of the original sample and 퐶푑 is the concentration of the duplicate sample.

Acceptable RPD limits for field quality control measures such as duplicates, are generally two times the published acceptable RPD limits for laboratory quality control measures (CCME, 2016). As such the upper bounds for acceptable RPD values for soil and groundwater are presented in the table below:

Table 4: Acceptable RPD Values for Field Duplicates

3. RESULTS

3.1 Site Background

3.1.1 Topography and Drainage

Regional topography in the vicinity of the site slopes north/northeast towards the Ottawa River (MNRF, 2020) The Site and surrounding area is relatively flat, with a ground surface elevation of approximately 43-44 mASL and gently sloping towards the river. The site is municipally-serviced and drainage on the streets and neighbouring properties is collected by storm sewers.

3.1.2 Geology

The Site and surrounding area is located in the physiographic region known as the Russell and Prescott Sand Plains (Chapman & Putnam, 2007). The overburden consists of stone- poor, sandy silt to silty sand-textured glacial till on Paleozoic terrain (Ontario Geological Survey, 2003). The bedrock geology consists of Paleozoic-aged sandstone, shale, limestone and dolostone, of the Rockcliffe Formation (Armstrong & Dodge, 2007).

3.1.3 Hydrogeology

The regional groundwater flow system is likely a subdued replica of the regional topography in the area. Regional groundwater is expected to flow north/northeast towards the Ottawa River. Local variations in this groundwater flow regime may exist due to the presence of highly permeable soil layers associated with utility trenches beneath Chenail Blvd or resulting from the placement of permeable soil as part of infilling activities.

The site is not located within any Source Protection Area and is not within any Intake Protection Zones (SNCA, 2010) .

3.2 Environmental Field Investigation

The environmental field investigation was performed in three (3) stages, starting in September 2019 and ending in July 2020. Specifically, it consisted of the following:

 Drilling four (4) boreholes (BH1 to BH4) on September 26th, 2019. The boreholes were advanced to depths between 4.9 and 5.5 mbgs.

 Installation of monitoring wells in all four (4) boreholes and completion of groundwater sampling on October 2nd, 2019.

 Drilling four (4) additional boreholes (BH5 to BH8) on November 29th, 2019, to further delineate findings from the first stage of drilling. These boreholes were advanced to depths between 4.6and 5.1 mbgs.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 11

 Installation of monitoring wells in these four (4) additional boreholes and completion of groundwater sampling on December 6th, 2019.

 Drilling six (6) boreholes (BH9 to BH14) from July 23rd to 24th, 2020, in the presumed contaminant source area. These boreholes were advanced to depths between 4.3 to 5.5 mbgs.

 Installation of monitoring wells in all six (6) of these boreholes and completion of groundwater sampling on July 28th, 2020. Prior to sampling, groundwater monitoring was completed in all 14 monitoring wells on July 28th, 2020 to obtain static water levels.

 Collection of soil and groundwater samples for analysis of the contaminants of concern, which included: metals, PAHs, PHCs and VOCs

This investigation was generally consistent with the proposed investigation plan. The drilling and monitoring well installation was performed by George Downing Estate Drilling Ltd. (Downing) of Grenville-sur-la-rouge, . Downing is a licensed well contractor with staff who are licensed well technicians in accordance with R.R.O. 1990, Reg. 903. The analytical testing was performed by ALS Environmental. The investigation derived waste was collected and disposed of by Clean Water Works (CWW) and Veolia.

A site plan showing the borehole and monitoring well locations can be seen on Figure 1 in Appendix B.

3.3 Soil Conditions

Details of the subsurface conditions encountered during drilling are presented on the borehole logs in Appendix C.

Generally speaking, the soil stratigraphy at the site consisted of topsoil or asphaltic concrete, underlain by a significant quantity of fill which was overlying native silty clay and/or silty sand. Compact to very dense glacial till, that was predominantly silty sand, was also encountered at the bottom of 11 of the 14 boreholes.

The encountered fill thicknesses ranged from 1.0 to 3.6 m and consisted of sand, silty sand, gravelly sand, clayey sand, silty gravel and peat. Various debris, including glass, brick, asphalt, concrete and metal were observed in the fill from all boreholes except BH8 and BH13. Coal and/or slag was also observed in boreholes BH10, BH11 and BH12, all located along the southern ROW of Chenail Blvd. Varying amounts of organic matter were noted in the fill, as well as a layer of wood chips and pieces in BH6. These wood chips were observed in the deep fill from BH6 and had a noticeable chemical odour. They may have been waste from the Canadian International Pulp and Paper mill, which was historically located west of the site. As mentioned in section 1.2, it was rumored that some material from this mill was used to fill in the former water lot shown on Figure 2 in Appendix B.

For boreholes BH1 to BH8, no field evidence of contamination was observed in the native soil encountered during drilling (i.e. silty clay and silty sand till). The lack of field evidence was supported by the relatively low headspace vapour readings that were measured for soil samples from these boreholes. CGI readings ranged from 0 to 190 ppm (from BH3 SA8) and

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 12

PID readings ranged from 0 to 6 ppm. Vapour readings at these levels are not indicative of any significant PHC or VOC contamination in the soil.

Boreholes BH9 to BH14 on the other hand, all had noticeable field evidence of contamination in the native soil. This included faint to strong hydrocarbon odours and black staining. Headspace vapour readings for soil from these boreholes were elevated and supported these observations. CGI readings ranged from 0 to 2900 ppm (from BH10 SA4) and PID readings ranged from 0 to 2000 ppm (from BH10 SA3). All six (6) of these boreholes had at least one vapour reading above 250 ppm. These results suggest the potential presence of PHC and VOC contamination in the soil.

3.4 Groundwater Conditions and Hydrogeology

The results of groundwater monitoring performed on July 28th, 2020 are summarized in Table 5 below. This includes the recorded vapour readings at the top of the piezometer, the measured static water levels and the calculated groundwater elevations for each monitoring well at the site.

No light non-aqueous phase liquid (LNAPL) was detected in any of the monitoring wells during this monitoring event.

The measured groundwater elevations at all monitoring wells and the interpreted horizontal groundwater flow direction in the shallow overburden at the site is shown on Figure 3 in Appendix B. As shown on this figure, local groundwater flow is predominantly to the east/northeast, towards the Ottawa River. There also appears to be a southeast flow path in the middle of the site, near wells BH5, BH6, BH9 and BH11. This interpretation of the local groundwater flow does not suggest that any bulk contaminant mass is occurring to the north.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 13

In terms of groundwater quality, nine (9) wells showed signs of contamination during purging and sampling. An organic/hydrogen sulfide odour was noted in the groundwater from BH1 and BH8. This can be indicative of water with a depleted amount of dissolved oxygen due to the presence of petroleum hydrocarbons. A slight sheen/film was also observed on the surface of the purge water from BH5, while a faint hydrocarbon odour was noted on the purge water from BH11, BH13 and BH14. The wells that showed the greatest signs of contamination were BH6, BH9 and BH10. Purge water from BH9 and BH10 had strong hydrocarbon odours while the purge water from BH6 had a strong hydrocarbon odour and a visible rainbow sheen.

Vapour readings collected during groundwater monitoring were taken immediately after removal of the J-Plug, using an RKI Eagle II. Vapour readings were not collected from BH1, BH7 and BH8 because the battery on the RKI Eagle II died before they could be collected. As seen in Table 5, elevated vapour readings were measured in monitoring wells BH3, BH6, BH9, BH10, BH11 and BH14. With the exception of BH3, all of these wells had evidence of contamination in the purge water to support these readings.

3.5 Applicable Standards

Provincial standards described in the Ministry of the Environment, Conservation and Parks (MECP) document entitled “Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act” dated April 15, 2011, are currently used for the assessment of potentially contaminated sites in the context of Ontario Regulation (“O. Reg.”) 153/04 as amended.

The following characteristics were noted for the site and were used in selecting the applicable Site Condition Standards (SCS):

 The site and surrounding lands are serviced by a municipal drinking water supply that does not use groundwater as its source (SNCA, 2010);

 The site is not considered a shallow soil property as less than 1/3 of the site consists of soil equal to or less than 2 metres in depth beneath the soil surface.

 The investigated portions of the site were road right-of-ways and a parking lot, which are considered community land use. That said, one of the property parcels is zoned as a Municipal Park. As a conservative measure, parkland was considered the applicable land use for the site;

 Two of the property parcels that make up the site includes land that is within 30 m of a water body (the Ottawa River). That said, the portions of these parcels that are abutting surface water are a fair distance from the points of investigation and the potential contaminant sources. The risks associated with proximity to a water body are not considered applicable for the site. The standards for land use within 30 m of a waterbody were not used.

 Coarse soil texture was considered for the site (conservative approach) as no grain size analysis was performed as part of this field program.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 14

Based on the above considerations, the following SCSs were selected to assess the soil and groundwater quality at the site:

 For soil: MECP 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. Residential/Parkland/ Institutional Property Use, coarse-textured soils, 2011 (MECP Table 3).

 For groundwater: MECP 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. All Types of Property Use, coarse-textured soils, 2011 (MECP Table 3).

Soil TCLP results were compared to Schedule 4: Leachate Quality Criteria of the General – Waste Management Regulation, RRO 1990, Reg. 347 under the Environmental Protection Act.

3.6 Soil Analytical Results

The soil analytical results for metals, PAH, PHC and VOC are presented in Tables D1, D2, D3 and D4 in Appendix D. The analytical results from the TCLP analyses are presented in Table D9 in Appendix D.

The soil analytical results are also shown on Figure 4 in Appendix B.

The laboratory Certificates of Analysis for soil and the TCLP analyses are provided in Appendix E.

3.7 Groundwater Analytical Results

The groundwater analytical results for metals, PAH, PHC and VOC are presented in Tables D5, D6, D7 and D8 in Appendix D. The groundwater analytical results are also shown on Figure 5 in Appendix B.

Laboratory Certificates of Analysis for groundwater are provided in Appendix D.

3.8 Quality Assurance/Quality Control

The field QC samples included six (6) blind duplicate soil samples (BH2 SA31, BH5 SA12, BH1 SA21, BH6 SA16, BH12 SA17 and BH13 SA15) and three (3) blind duplicate groundwater samples (BH21, DUP and DUP).

The blind duplicates were evaluated using the RPD method described in section 2.9. Acceptable RPD values were obtained for all three (3) groundwater duplicates.

Acceptable RPD values were obtained for all soil duplicates except BH6 SA16 and BH13 SA15, which had PHC and/or BTEX parameters exceed the acceptable RPD values. These high RPD results and concentration discrepancies are likely due to soil heterogeneity. Despite this heterogeneity, the concentrations of PHC and BTEX in both the parent and

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 15

duplicate samples BH6 SA6/SA16 and BH13 SA5/SA15 satisfied the MECP Table 3 standards.

No data quality issues were identified based on evaluation of the analytical results obtained for the parent and duplicate samples.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 16

4. EVALUATION OF RESULTS

4.1 Soil Contamination

4.1.1 Metals

A total of 13 soil samples, including two (2) duplicates were collected and submitted for metals analysis. Eight (8) of these samples were of surface soil (0 to 1.5 mbgs), while the remaining five (5) were of subsurface soil. All of these samples were collected from fill material.

The fill from five (5) boreholes had one or more metals parameters exceed MECP Table 3 standards. This included fill from BH2 (lead), BH4 (copper), BH7 (lead, mercury), BH8 (lead, mercury, zinc) and BH10 (arsenic, lead). The fill from BH4, BH8 and BH10 also had one or more PAH exceedances, which are discussed in the section below.

The source of these impacts are believed to be the result of poor quality fill, potentially used during the construction of the Chenail Blvd ROW or in the case of BH7 and BH8, the Belle Rive Street ROW. Of particular concern is the fill quality at BH10. The impacted sample from this borehole was collected at surface (from a depth of 0 to 0.61 mbgs) and had visible coal pieces and slag. The arsenic concentration in this fill material was 2 times greater than the standard.

4.1.2 PAH

A total of 18 soil samples, including three (3) duplicates were collected and submitted for PAH analysis. Six (6) of these samples were collected from the surficial fill (0 to 1.5 mbgs), four (4) samples were collected from the subsurface fill and eight (8) samples were collected from the native soil. Samples were submitted for PAH analysis to investigate poor quality fill or impacts from released petroleum products.

PAH parameters were detected in all six (6) surficial fill samples, but only the fill from BH10 had PAH concentrations above MECP Table 3 standards. The fill from this borehole had coal pieces and slag suggesting the PAHs are likely the result of poor quality fill.

Three (3) of the four (4) subsurface fill samples had PAH concentrations above MECP Table 3 standards. Minor exceedances were detected in the soil from BH4 and BH8, and were likely the result of the use of poor quality fill. Significant PAH contamination was, however, detected in the fill from BH1. This soil had exceedances of multiple PAH parameters including anthracene, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, fluoranthene and indeno(1,2,3,-cd)pyrene. The concentrations of these PAHs were at least 20 times greater than the applicable standard.

The source of this PAH contamination is unknown. The contamination consisted mostly of unsubstituted, high molecular weight PAHs, These PAHs would not be found in gasoline and would only be present at low levels in heating oil. Considering this borehole is located north of the inferred limits of the former Rene Bertrand fuel oil depot and Pilon Esso Terminal, the most likely source seems to be spills and contaminant releases associated with the former CNR railway line.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 17

Of the eight (8) samples submitted from the native soil, three (3) had PAH exceedances (BH6 SA6, BH9 SA6, BH10 SA3). The submitted sample from BH6 consisted predominantly of native soil, but also included some of the overlying fill material, which contained wood chips, potentially from the former paper mill. It is believed this poor quality fill is the source of the contamination.

Samples from BH9 and BH10 had naphthalene and/or 1+2 methylnaphthalene present above MECP Table 3 standards. These are the lighter, more volatile PAHs, which are known constituents of heating oil. Due to their presence in native soil and the lack of exceedances for the other unsubstituted PAHs, this soil contamination is potentially the result of a heating oil release. Further details on the impacts at BH9 and BH10 are provided in the PHC and BTEX section below.

4.1.3 PHC and BTEX

A total of 15 soil samples, including two (2) duplicates, were collected and submitted for PHC and BTEX analysis. An additional six (6) soil samples, including one (1) duplicate, were submitted for PHC F2-F4 analysis, while two (2) soil samples, including one (1) duplicate, were submitted for PHC F1 and BTEX analysis.

All but one of these samples was collected from native subsurface soil, in the vicinity of, or below the water table. The remaining sample was collected from deep fill below the water table.

PHC and/or BTEX parameters exceeded the MECP Table 3 standards in soil from boreholes BH7, BH9 and BH10. Boreholes BH9 and BH10 were both located in the vicinity of the property that was used as the Rene Bertrand Fuel Oil depot, and later as the Pilon Esso terminal. Both of these property uses had ASTs containing unknown petroleum products. These could have included gasoline, heating oil or heavy fuel oil.

PHC and/or BTEX parameters were detected in soil samples from boreholes BH6 (benzene, PHC F3, PHC F4), BH11 (benzene), BH 13 (BTEX, PHC F1 to F3) and BH14 (PHC F2), but none of the detected concentrations exceeded the MECP Table 3 standards.

No PHC or BTEX parameters were detected in any of the soil samples submitted from boreholes BH1 to BH5, BH8 and BH12.

Soil from BH9 had PHC F2 exceedances while soil from BH10 was the most impacted, with exceedances of benzene, ethylbenzene, xylenes and PHC F1 to F3. Elevated concentrations of BTEX and PHC F1 are expected when the source of contamination is gasoline, while elevated concentrations of PHC F2-F3 are expected for heating oil. Based on these results, either of these petroleum products could have been released into the ground. Seeing as these boreholes are the only ones with confirmed PHC and BTEX contamination in the soil, any contaminant mass in groundwater likely originated from this location.

The exceedance at BH7 was for PHC F3. BH7 is a fair distance from the former fuel oil depot and it is unlikely this contaminant mass originated from that industrial activity. A significant quantity of fill was encountered at BH7 (~3.6 m) and even though the impacted sample consisted mostly of silty sand that was considered native, the exceedance may be the result of poor quality fill. The fill from BH7 also had a noticeable amount of organic

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 18

matter, which may have contributed to the PHC F3 concentration. The lab generated chromatogram for this sample did not have a discernible unresolved complex mixture, a feature commonly associated with petroleum products. Based on this information, it is difficult to say if the PHC F3 exceedance is the result of petroleum products, naturally occurring organic matter or both.

4.1.4 VOC

A total of 17 soil samples, including three (3) duplicates were submitted for VOC analysis. Other than soil samples from BH9, BH10 and BH13, no VOC parameters were detected in soil from any of the boreholes.

Hexane was detected in soil from BH9 and BH13, but was not present above the MECP Table 3 standards. Hexane exceedances were detected in soil from BH 10. The presence of this contaminant is related to the PHC and BTEX contamination discussed above.

4.1.5 TCLP

Three (3) TCLP samples were collected from the soil cuttings generated during the drilling program. These samples were analyzed for leachable metals and benzo(a)pyrene concentrations generated from a TCLP analytical procedure. Two (2) samples were also analyzed for leachable VOC parameters.

All soil leachate results satisfied the Leachate Quality Criteria found in Schedule 4 of R.R.O. 1990, Reg. 347. As such, the soil at the site is not considered hazardous waste under R.R.O. 1990, Reg. 347.

4.2 Groundwater Contamination

4.2.1 Metals

A total of ten (10) groundwater samples, including two (2) duplicates, were field filtered and analyzed for concentrations of dissolved metals.

No metal exceedances were detected in any of the groundwater samples.

4.2.2 VOC

A total of 17 groundwater samples, including three (3) duplicates, were collected and analyzed for concentrations of VOCs.

Other than hexane, no VOC parameters were detected in any of the submitted water samples. This includes the more water soluble gasoline additives such as lead scavengers (ethylene dibromide, 1,2-dichloroethane), which were historically added to leaded gasoline, and methyl-tert-butyl ether (MTBE) which serves as an oxygenate in modern gasoline.

Hexane was detected in groundwater from BH9, BH10 and BH11 but at concentrations significantly below the MECP Table 3 standard.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 19

4.2.3 PAH, PHC and BTEX

A total of 17 groundwater samples, including three (3) duplicates, were collected and analyzed for PAH, PHC and BTEX parameters.

PAH exceedances were detected in the groundwater from BH1 and BH6. Groundwater from these wells also had PHC F3 and F4 above the MECP Table 3 standards.

PHC F2 exceedances were detected in the groundwater from BH9, BH11, BH13 and BH14, while benzene exceedances were also noted in BH9.

PAH, PHC and BTEX parameters were detected in other monitoring wells but at concentrations that met the MECP table 3 standards.

These results suggest there may be two (2) groundwater plumes present at the site. One (1) characterized by PHC F2 contamination (Plume 1) and the other consisting of PAH and PHC F3-F4 impacts, but characterized predominantly by PHC F3 contamination (Plume 2).

It must be noted that data qualifiers were applied to all PAH and PHC results due to the inclusion of visible sediment in the water sample. High molecular weight hydrocarbons such as PHC F3/F4 and the detected PAH parameters have low water solubility and will preferentially adsorb to soil/sediment. The inclusion of contaminated sediment in the analysis of dissolved phase groundwater contaminants can bias results high (ALS Environment, 2020).

Levels of total suspended solids (TSS) were determined for groundwater samples from wells BH9 to BH14 in order to assess any impacts contaminated sediment/soil may have had on the submitted samples. TSS results for these wells ranged from 1,060 to 11,800 mg/L, with an average of 6,400 mg/L. These TSS readings are very high and likely representative of the other wells on site, which all yielded purge water that was opaque and described as “silty”. This is especially relevant for monitoring wells BH1 and BH6, which had concentrations of PAH and PHC F3-F4 that exceeded reported solubility limits.

Re-sampling of these wells with a peristaltic pump using a low-flow methodology would limit the sediment collected in the groundwater samples and allow for a more accurate measurement of the dissolved phase concentrations.

4.3 Plume 1 Details and Delineation

Regarding Plume 1, it was documented in section 4.1.3, that there is soil contamination present at BH9 and BH10, likely originating from the former Rene Bertrand fuel oil depot and/or the Pilon Esso Terminal. This soil contamination appears to be the result of heating oil and possibly gasoline releases and has resulted in groundwater contamination at this location. Heating oil generally consists of PHC F2-F3, alkylated PAHs (1+2 methylnaphthalene) and lesser levels of unsubstituted PAHs (ALS Environment, 2019). Gasoline on the other hand, consists predominantly of PHC F1 and BTEX, the lighter, more volatile and more water soluble hydrocarbons. Other than the benzene exceedance at BH9, there is little evidence of gasoline impacts in the groundwater. The industrial activities that are believed to be the contaminant sources reportedly existed from 1930 to 1992. Any released petroleum products would have been in the ground for at minimum 28 years,

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 20

allowing significant time for contaminant weathering to occur. The main weathering mechanisms are evaporation, biodegradation and water washing and gasoline contaminants are most susceptible to these processes (ALS Environment, 2019). If there were gasoline releases this may explain why PHC F1 and BTEX exceedances were not observed in the groundwater.

Overall, Plume 1 is characterized by elevated PHC F2 concentrations, likely resulting from heating oil releases. The inferred extent of this plume is shown on Figure 6 in Appendix B. The plume is considered to be delineated to the north, west and east. Additional investigations to confirm the boundaries to the south, southeast and southwest are not required at this time. This plume delineation appears to show the dissolved contaminant mass migrating to the east and southeast, in line with the local groundwater flow paths shown on Figure 3 in Appendix B.

4.4 Plume 2 Details and Delineation

Plume 2 is characterized by PHC F3 concentrations but also contains elevated concentrations of high-molecular weight PAHs (4-6 rings) and PHC F4. These contaminants preferentially adsorb to soil, have very low water solubility and limited mobility in groundwater. As seen on Figure 7 in Appendix B, the inferred extent of this plume is centered around monitoring wells BH1 and BH6. These were the only two (2) wells with elevated concentrations of PAHs or PHC F3-F4 in the groundwater. Significant PAH contamination was also confirmed in the soil at the water table from BH1, while purge water from BH6 had a strong hydrocarbon odour and was the only well to produce water with a visible rainbow sheen. The source of this plume appears to have been a contaminant release that occurred in the vicinity of BH1 and BH6.

As discussed in section 4.1.2, there remains uncertainty regarding the source of this contamination. It is not known what was stored in the ASTs at the fuel oil depots but the presence of PHC F3-F4 and high-molecular weight PAHs suggest the release of a heavier, less refined petroleum product like heavy fuel oil. Given these wells are located north of the inferred limits of the former Rene Bertrand fuel oil depot and Pilon Esso Terminal, the most likely source seems to be spills and contaminant releases of heavy fuel oil from the former CNR railway line.

Plume 2 is considered delineated to the south and west. Additional investigations to confirm the boundaries to the north and east are not required at this time.

4.5 Preliminary Groundwater Risk Evaluation

Contaminated groundwater poses a risk if an exposure pathway exists between the contaminants in the groundwater and a receptor or group of receptors. The three (3) main pathways associated with contaminated groundwater are:

1. Ingestion of contaminated groundwater when groundwater is used as a potable water source.

2. Inhalation of contaminants that volatilize from ground water and enter indoor air, when contaminated groundwater is present beneath structures.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 21

3. Discharge of contaminated groundwater into waterbodies that are occupied by aquatic life.

As discussed in section 3.5, the local groundwater is not used as a potable water supply and the plumes are sufficient distance from the nearest water body (>30m) that risk to aquatic life is considered low.

Furthermore, the contaminants found in Plume 2 are considered non-volatile and unlikely to impact indoor air. The contaminants in Plume 1 (PHC F2) are volatile, but the measured concentrations were below levels that are considered to pose an unacceptable risk for vapour intrusion into residential buildings (2,300 µg/L) (MECP, 2011). Both of these plumes are also not currently located beneath any existing residential buildings.

In their current state, the groundwater plumes do not appear to be resulting in substantial risk to on-site receptors and immediate remedial action is not required.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 22

5. CONCLUSIONS

Based on the findings of the Phase II ESA, the following conclusions are made:

1. Generally speaking, the soil stratigraphy at the site consists of topsoil or asphaltic concrete, underlain by a significant quantity of fill which was overlying native silty clay and/or silty sand glacial till. The encountered fill thicknesses ranged from 1.0 to 3.6 m and consisted of a variety of soil textures. Debris, including wood pieces, glass, brick, asphalt, concrete and metal, as well as coal, slag and some organic matter were observed in the fill. Native soil in select boreholes also had faint to strong hydrocarbons odours, black staining and elevated headspace vapour readings.

2. The interpreted horizontal groundwater flow direction is predominantly to the east/northeast, towards the Ottawa River. There appears to be a local southeast flow path in the middle of the site, at the location of the former Rene Bertrand fuel oil depot. This information suggests that bulk contaminant mass transport is not occurring to the north.

3. Metals and/or PAH exceedances were detected in the fill from six (6) boreholes spread across the site. Given the observations of debris found in the fill, these exceedances are believed to be the result of poor quality fill , either used during the construction of the Chenail Blvd and Belle Rive Street ROW or impacted by the historical industrial activities and rail tracks/spurs that existed at the site. Of particular concern is the fill quality at BH10. The surficial fill in this borehole (from 0 – 0.6 mbgs) had visible coal and slag pieces and confirmed metal and PAH contamination.

4. PHC and BTEX contamination was confirmed in the native soil from boreholes BH9 and BH10. This soil also had exceedances of the lighter PAH parameters (naphthalene and/or 1+2 methylnaphthalene). Both of these boreholes are located in the vicinity of the former Rene Bertrand fuel oil depot/Pilon Esso terminal. Based on the detected contaminants, the source of these impacts appears to have been heating oil and gasoline releases from the ASTs at these former depots.

5. PHC F2 exceedances were detected in the groundwater from BH9, BH11, BH13 and BH14. The maximum concentration occurred at BH9, which also had a benzene exceedance. It is likely the petroleum product releases that caused the soil contamination at BH9 and BH10 also caused these groundwater impacts. This PHC F2 contamination resulted in a plume (given the ID Plume 1) that is centered around BH9. The plume is considered to be delineated to the north, west and east. Additional investigations to confirm the boundaries to the south, southeast and southwest are not required at this time

6. Significant PAH contamination was confirmed in the subsurface fill at BH1. Groundwater from BH1 and BH6, the adjacent monitoring well, also had exceedances of high-molecular weight PAHs and PHC F3-F4. This contaminant profile suggests a different source than that for Plume 1. PHC F3-F4 are characteristic of more viscous, residual petroleum products like heavy fuel oil. Given that this plume is located north of the inferred limits of the former Rene Bertrand fuel

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 23

oil depot and Pilon Esso Terminal, the most likely source seems to be spills and contaminant releases of heavy fuel oil from the former CNR railway line

7. The PAH and PHC F3-F4 contamination has resulted in a groundwater plume (Plume 2). These contaminants have low water solubility and limited mobility in groundwater. Plume 2 is considered delineated to the south and west. Additional investigation to confirm the boundaries to the north and east is not required at this time. It is noted that some contaminant mass may have migrated onto adjacent properties.

8. A preliminary risk evaluation suggests that, in their current state, these groundwater plumes are not resulting in any unacceptable risk to on-site receptors. Immediate remedial action is not required.

9. No metal or VOC exceedances were detected in the groundwater. These are no longer considered COCs in the groundwater at the site.

Phase II ESA – East End of Chenail Blvd, Hawkesbury, ON August 2020 24

6. RECOMMENDATIONS

6.1 Additional Groundwater Sampling

In order to accurately assess the risk from the two (2) groundwater plumes, an additional groundwater sampling program is recommended to obtain more representative dissolved phase concentrations. As discussed in section 4.2.3, the inclusion of sediment in the submitted samples means the reported groundwater concentrations are potentially biased high.

Monitoring wells BH1, BH6, BH9, BH10, BH11, BH13 and BH14 should be included in this sampling program. Sampling should be carried out following a low-flow sampling procedure to minimize TSS levels and samples should be submitted for analysis of PAH and PHC F2- F4.

The fact that the groundwater contamination in Plume 2 appears to extend to adjacent private properties should be disclosed to the MECP.

6.2 Shallow Soil Sampling Program and Remediation

The surficial soil contamination at BH10 likely poses an unacceptable risk. It is recommended that, at minimum, the Town of Hawkesbury perform a shallow soil investigation, along the southern shoulder of Chenail Blvd, focusing on the top 1m of soil, in order to delineate the impacted fill.

From this program, contaminated soil quantities can be estimated and remediation carried out via excavation and disposal at an MECP licensed waste disposal facility. The remedial excavation can be carried out to a maximum 1 m depth, such that a 1 m thick clean soil cap is placed above any remnant contaminated soil.

Sub-excavation of the PHC and BTEX contaminated soil at BH9 and BH10 should be discussed as part of this remedial excavation. The logistics of reaching this material (>1.5 m deep) are more complicated however, and the risk does not necessitate immediate action.

F1-F4-511-CALC-WT Soil F1-F4 Hydrocarbon Calculated CCME CWS-PHC, Pub #1310, Dec 2001-S Parameters

Analytical methods used for analysis of CCME Petroleum Hydrocarbons have been validated and comply with the Reference Method for the CWS PHC.

Hydrocarbon results are expressed on a dry weight basis.

In cases where results for both F4 and F4G are reported, the greater of the two results must be used in any application of the CWS PHC guidelines and the gravimetric heavy hydrocarbons cannot be added to the C6 to C50 hydrocarbons. In samples where BTEX and F1 were analyzed , F1-BTEX represents a value where the sum of Benzene, Toluene, Ethylbenzene and total Xylenes has been subtracted from F1.

In samples where PAHs, F2 and F3 were analyzed, F2-Naphth represents the result where Naphthalene has been subtracted from F2. F3-PAH represents a result where the sum of Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Dibenzo(a,h)anthracene, Fluoranthene, Indeno(1,2,3-cd)pyrene, Phenanthrene, and Pyrene has been subtracted from F3.

Unless otherwise qualified, the following quality control criteria have been met for the F1 hydrocarbon range: 1. All extraction and analysis holding times were met. 2. Instrument performance showing response factors for C6 and C10 within 30% of the response factor for toluene. 3. Linearity of gasoline response within 15% throughout the calibration range.

Unless otherwise qualified, the following quality control criteria have been met for the F2-F4 hydrocarbon ranges: 1. All extraction and analysis holding times were met. 2. Instrument performance showing C10, C16 and C34 response factors within 10% of their average. 3. Instrument performance showing the C50 response factor within 30% of the average of the C10, C16 and C34 response factors. 4. Linearity of diesel or motor oil response within 15% throughout the calibration range. F1-HS-511-WT Soil F1-O.Reg 153/04 (July 2011) E3398/CCME TIER 1-HS

F2-F4-511-WT Soil F2-F4-O.Reg 153/04 (July 2011) CCME Tier 1

Petroleum Hydrocarbons (F2-F4 fractions) are extracted from soil with 1:1 hexane:acetone using a rotary extractor. Extracts are treated with silica gel to remove polar organic interferences. F2, F3, & F4 are analyzed by GC-FID. F4G-sg is analyzed gravimetrically.

Notes: 1. F2 (C10-C16): Sum of all hydrocarbons that elute between nC10 and nC16. 2. F3 (C16-C34): Sum of all hydrocarbons that elute between nC16 and nC34. 3. F4 (C34-C50): Sum of all hydrocarbons that elute between nC34 and nC50. 4. F4G: Gravimetric Heavy Hydrocarbons 5. F4G-sg: Gravimetric Heavy Hydrocarbons (F4G) after silica gel treatment. 6. Where both F4 (C34-C50) and F4G-sg are reported for a sample, the larger of the two values is used for comparison against the relevant CCME guideline for F4. 7. F4G-sg cannot be added to the C6 to C50 hydrocarbon results to obtain an estimate of total extractable hydrocarbons. 8. This method is validated for use. 9. Data from analysis of validation and quality control samples is available upon request. 10. Reported results are expressed as milligrams per dry kilogram, unless otherwise indicated.

MET-200.2-CCMS-WT Soil Metals in Soil by CRC ICPMS EPA 200.2/6020A (mod)

Soil/sediment is dried, disaggregated, and sieved (2 mm). For tests intended to support Ontario regulations, the <2mm fraction is ground to pass through a 0.355 mm sieve. Strong Acid Leachable Metals in the <2mm fraction are solubilized by heated digestion with nitric and hydrochloric acids. Instrumental analysis is by Collision / Reaction Cell ICPMS.

Limitations: This method is intended to liberate environmentally available metals. Silicate minerals are not solubilized. Some metals may be only partially recovered (matrix dependent), including Al, Ba, Be, Cr, S, Sr, Ti, Tl, V, W, and Zr. Elemental Sulfur may be poorly recovered by this method. Volatile forms of sulfur (e.g. sulfide, H2S) may be excluded if lost during sampling, storage, or digestion.

Sample Parameter Qualifier Definitions: Qualifier Description E Matrix Spike recovery outside ALS DQO due to heterogeneous analyte background in sample. LCS-L Lab Control Sample recovery was below ALS DQO. Reference Material and/or Matrix Spike results were acceptable. Non-detected sample results are considered reliable. Other results, if reported, have been qualified. MES Data Quality Objective was marginally exceeded (by < 10% absolute) for < 10% of analytes in a Multi-Element Scan / Multi-Parameter Scan (considered acceptable as per OMOE & CCME). MS-B Matrix Spike recovery could not be accurately calculated due to high analyte background in sample. RPD-NA Relative Percent Difference Not Available due to result(s) being less than detection limit.

Hold Time Exceedances: All test results reported with this submission were conducted within ALS recommended hold times.

ALS recommended hold times may vary by province. They are assigned to meet known provincial and/or federal government requirements. In the absence of regulatory hold times, ALS establishes recommendations based on guidelines published by the US EPA, APHA Standard Methods, or Environment Canada (where available). For more information, please contact ALS.

The ALS Quality Control Report is provided to ALS clients upon request. ALS includes comprehensive QC checks with every analysis to ensure our high standards of quality are met. Each QC result has a known or expected target value, which is compared against pre- determined data quality objectives to provide confidence in the accuracy of associated test results.

Please note that this report may contain QC results from anonymous Sample Duplicates and Matrix Spikes that do not originate from this Work Order. ALS Sample ID: L2356568-2 Client Sample ID: BH1-SA7 500

Methods Listed (if applicable): ALS Test Code Matrix Test Description Method Reference***

HG-TCLP-WT Waste Mercury (CVAA) for O.Reg 347 EPA 1631E

This analysis is carried out in accordance with the extraction procedure outlined in "Test Methods for Evaluating Solid Waste - Physical/Chemical Methods Volume 1C" SW-846 EPA Method 1311, published by the United States Environmental Protection Agency (EPA). In summary, the sample is extracted at a 20:1 liquid to solids ratio for 16 to 20 hours using either extraction fluid #1 (glacial acetic acid, water and sodium hydroxide) or extraction fluid #2 (glacial acetic acid), depending on the pH of the original sample. The extract is then filtered through a 0.6 to 0.8 micron glass fibre filter and analysed using atomic absorption spectrophotometry (EPA 1631E). LEACH-TCLP-WT Waste Leachate Procedure for Reg 347 EPA 1311

Inorganic and Semi-Volatile Organic contaminants are leached from waste samples in strict accordance with US EPA Method 1311, "Toxicity Characteristic Leaching Procedure" (TCLP). Test results are reported in leachate concentration units (normally mg/L). MET-TCLP-WT Waste O.Reg 347 TCLP Leachable EPA 6020B Metals

This analysis is carried out in accordance with the extraction procedure outlined in "Test Methods for Evaluating Solid Waste - Physical/Chemical Methods Volume 1C" SW-846 EPA Method 1311, published by the United States Environmental Protection Agency (EPA). In summary, the sample is extracted at a 20:1 liquid to solids ratio for 16 to 20 hours using either extraction fluid #1 (glacial acetic acid, water and sodium hydroxide) or extraction fluid #2 (glacial acetic acid), depending on the pH of the original sample. The extract is then filtered through a 0.6 to 0.8 micron glass fibre filter. Instrumental analysis of the digested extract is by collision cell inductively coupled plasma - mass spectrometry (modifed from EPA Method 6020B). PAH-TCLP-WT Waste PAH for O. Reg 347 SW846 8270 (PAH)

Samples are leached according to TCLP protocol and then the aqueous leachate is extracted and the resulting extracts are analyzed on GC/MSD. Depending on the analytical GC/MS column used benzo(j)fluoranthene may chromatographically co-elute with benzo(b)fluoranthene or benzo(k)fluoranthene.

GLOSSARY OF REPORT TERMS

Surrogates are compounds that are similar in behaviour to target analyte(s), but that do not normally occur in environmental samples. For applicable tests, surrogates are added to samples prior to analysis as a check on recovery. In reports that display the D.L. column, laboratory objectives for surrogates are listed there. mg/kg - milligrams per kilogram based on dry weight of sample mg/kg wwt - milligrams per kilogram based on wet weight of sample mg/kg lwt - milligrams per kilogram based on lipid-adjusted weight mg/L - unit of concentration based on volume, parts per million. < - Less than. D.L. - The reporting limit. N/A - Result not available. Refer to qualifier code and definition for explanation.

Test results reported relate only to the samples as received by the laboratory. UNLESS OTHERWISE STATED, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION. Analytical results in unsigned test reports with the DRAFT watermark are subject to change, pending final QC review.

Application of guidelines is provided "as is" without warranty of any kind, either expressed or implied, including, but not limited to, fitness for a particular purpose, or non-infringement. ALS assumes no responsibility for errors or omissions in the information. Guideline limits are not adjusted for the hardness, pH or temperature of the sample (the most conservative values are used). Measurement uncertainty is not applied to test results prior to comparison with specified criteria values. Quality Control Report

WT ALS ENVIRONMENTAL - WATERLOO, ONTARIO, CANADA GLOSSARY OF REPORT TERMS

Surrogates are compounds that are similar in behaviour to target analyte(s), but that do not normally occur in environmental samples. For applicable tests, surrogates are added to samples prior to analysis as a check on recovery. In reports that display the D.L. column, laboratory objectives for surrogates are listed there. mg/kg - milligrams per kilogram based on dry weight of sample mg/kg wwt - milligrams per kilogram based on wet weight of sample mg/kg lwt - milligrams per kilogram based on lipid-adjusted weight mg/L - unit of concentration based on volume, parts per million. < - Less than. D.L. - The reporting limit. N/A - Result not available. Refer to qualifier code and definition for explanation.

Test results reported relate only to the samples as received by the laboratory. UNLESS OTHERWISE STATED, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION. Analytical results in unsigned test reports with the DRAFT watermark are subject to change, pending final QC review.

Application of guidelines is provided "as is" without warranty of any kind, either expressed or implied, including, but not limited to, fitness for a particular purpose, or non-infringement. ALS assumes no responsibility for errors or omissions in the information. Guideline limits are not adjusted for the hardness, pH or temperature of the sample (the most conservative values are used). Measurement uncertainty is not applied to test results prior to comparison with specified criteria values. Quality Control Report

MET-200.2-CCMS-WT Soil Metals in Soil by CRC ICPMS EPA 200.2/6020A (mod)

Soil/sediment is dried, disaggregated, and sieved (2 mm). For tests intended to support Ontario regulations, the <2mm fraction is ground to pass through a 0.355 mm sieve. Strong Acid Leachable Metals in the <2mm fraction are solubilized by heated digestion with nitric and hydrochloric acids. Instrumental analysis is by Collision / Reaction Cell ICPMS.

Limitations: This method is intended to liberate environmentally available metals. Silicate minerals are not solubilized. Some metals may be only partially recovered (matrix dependent), including Al, Ba, Be, Cr, S, Sr, Ti, Tl, V, W, and Zr. Elemental Sulfur may be poorly recovered by this method. Volatile forms of sulfur (e.g. sulfide, H2S) may be excluded if lost during sampling, storage, or digestion.

Methods Listed (if applicable): ALS Test Code Matrix Test Description Method Reference***

HG-TCLP-WT Waste Mercury (CVAA) for O.Reg 347 EPA 1631E

This analysis is carried out in accordance with the extraction procedure outlined in "Test Methods for Evaluating Solid Waste - Physical/Chemical Methods Volume 1C" SW-846 EPA Method 1311, published by the United States Environmental Protection Agency (EPA). In summary, the sample is extracted at a 20:1 liquid to solids ratio for 16 to 20 hours using either extraction fluid #1 (glacial acetic acid, water and sodium hydroxide) or extraction fluid #2 (glacial acetic acid), depending on the pH of the original sample. The extract is then filtered through a 0.6 to 0.8 micron glass fibre filter and analysed using atomic absorption spectrophotometry (EPA 1631E). LEACH-TCLP-WT Waste Leachate Procedure for Reg 347 EPA 1311

Inorganic and Semi-Volatile Organic contaminants are leached from waste samples in strict accordance with US EPA Method 1311, "Toxicity Characteristic Leaching Procedure" (TCLP). Test results are reported in leachate concentration units (normally mg/L). MET-TCLP-WT Waste O.Reg 347 TCLP Leachable EPA 6020B Metals

This analysis is carried out in accordance with the extraction procedure outlined in "Test Methods for Evaluating Solid Waste - Physical/Chemical Methods Volume 1C" SW-846 EPA Method 1311, published by the United States Environmental Protection Agency (EPA). In summary, the sample is extracted at a 20:1 liquid to solids ratio for 16 to 20 hours using either extraction fluid #1 (glacial acetic acid, water and sodium hydroxide) or extraction fluid #2 (glacial acetic acid), depending on the pH of the original sample. The extract is then filtered through a 0.6 to 0.8 micron glass fibre filter. Instrumental analysis of the digested extract is by collision cell inductively coupled plasma - mass spectrometry (modifed from EPA Method 6020B). PAH-TCLP-WT Waste PAH for O. Reg 347 SW846 8270 (PAH)

Samples are leached according to TCLP protocol and then the aqueous leachate is extracted and the resulting extracts are analyzed on GC/MSD. Depending on the analytical GC/MS column used benzo(j)fluoranthene may chromatographically co-elute with benzo(b)fluoranthene or benzo(k)fluoranthene. VOC-TCLP-WT Waste VOC for O. Reg 347 SW846 8260

A sample of waste is leached in a zero headspace extractor at 30–2 rpm for 18–2.0 hours with the appropriate leaching solution. After tumbling the leachate is analyzed directly by headspace , followed by GC/MS using internal standard quantitation.

GLOSSARY OF REPORT TERMS

Surrogates are compounds that are similar in behaviour to target analyte(s), but that do not normally occur in environmental samples. For applicable tests, surrogates are added to samples prior to analysis as a check on recovery. In reports that display the D.L. column, laboratory objectives for surrogates are listed there. mg/kg - milligrams per kilogram based on dry weight of sample mg/kg wwt - milligrams per kilogram based on wet weight of sample mg/kg lwt - milligrams per kilogram based on lipid-adjusted weight mg/L - unit of concentration based on volume, parts per million. < - Less than. D.L. - The reporting limit. N/A - Result not available. Refer to qualifier code and definition for explanation.

Test results reported relate only to the samples as received by the laboratory. UNLESS OTHERWISE STATED, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION. Analytical results in unsigned test reports with the DRAFT watermark are subject to change, pending final QC review.

Application of guidelines is provided "as is" without warranty of any kind, either expressed or implied, including, but not limited to, fitness for a particular purpose, or non-infringement. ALS assumes no responsibility for errors or omissions in the information. Guideline limits are not adjusted for the hardness, pH or temperature of the sample (the most conservative values are used).

WT ALS ENVIRONMENTAL - WATERLOO, ONTARIO, CANADA GLOSSARY OF REPORT TERMS

Surrogates are compounds that are similar in behaviour to target analyte(s), but that do not normally occur in environmental samples. For applicable tests, surrogates are added to samples prior to analysis as a check on recovery. In reports that display the D.L. column, laboratory objectives for surrogates are listed there. mg/kg - milligrams per kilogram based on dry weight of sample mg/kg wwt - milligrams per kilogram based on wet weight of sample mg/kg lwt - milligrams per kilogram based on lipid-adjusted weight mg/L - unit of concentration based on volume, parts per million. < - Less than. D.L. - The reporting limit. N/A - Result not available. Refer to qualifier code and definition for explanation.

Test results reported relate only to the samples as received by the laboratory. UNLESS OTHERWISE STATED, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION. Analytical results in unsigned test reports with the DRAFT watermark are subject to change, pending final QC review.

Application of guidelines is provided "as is" without warranty of any kind, either expressed or implied, including, but not limited to, fitness for a particular purpose, or non-infringement. ALS assumes no responsibility for errors or omissions in the information. Guideline limits are not adjusted for the hardness, pH or temperature of the sample (the most conservative values are used). Measurement uncertainty is not applied to test results prior to comparison with specified criteria values. Quality Control Report

Soil/sediment is dried, disaggregated, and sieved (2 mm). For tests intended to support Ontario regulations, the <2mm fraction is ground to pass through a 0.355 mm sieve. Strong Acid Leachable Metals in the <2mm fraction are solubilized by heated digestion with nitric and hydrochloric acids. Instrumental analysis is by Collision / Reaction Cell ICPMS.

Limitations: This method is intended to liberate environmentally available metals. Silicate minerals are not solubilized. Some metals may be only partially recovered (matrix dependent), including Al, Ba, Be, Cr, S, Sr, Ti, Tl, V, W, and Zr. Elemental Sulfur may be poorly recovered by this method. Volatile forms of sulfur (e.g. sulfide, H2S) may be excluded if lost during sampling, storage, or digestion.

Surrogates are compounds that are similar in behaviour to target analyte(s), but that do not normally occur in environmental samples. For applicable tests, surrogates are added to samples prior to analysis as a check on recovery. In reports that display the D.L. column, laboratory objectives for surrogates are listed there. mg/kg - milligrams per kilogram based on dry weight of sample mg/kg wwt - milligrams per kilogram based on wet weight of sample mg/kg lwt - milligrams per kilogram based on lipid-adjusted weight mg/L - unit of concentration based on volume, parts per million. < - Less than. D.L. - The reporting limit. N/A - Result not available. Refer to qualifier code and definition for explanation.

Test results reported relate only to the samples as received by the laboratory. UNLESS OTHERWISE STATED, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION. Analytical results in unsigned test reports with the DRAFT watermark are subject to change, pending final QC review.

Application of guidelines is provided "as is" without warranty of any kind, either expressed or implied, including, but not limited to, fitness for a particular purpose, or non-infringement. ALS assumes no responsibility for errors or omissions in the information. Guideline limits are not adjusted for the hardness, pH or temperature of the sample (the most conservative values are used). Measurement uncertainty is not applied to test results prior to comparison with specified criteria values. Quality Control Report

F1-F4-511-CALC-WT Soil F1-F4 Hydrocarbon Calculated CCME CWS-PHC, Pub #1310, Dec 2001-S Parameters

Analytical methods used for analysis of CCME Petroleum Hydrocarbons have been validated and comply with the Reference Method for the CWS PHC.

Hydrocarbon results are expressed on a dry weight basis.

In cases where results for both F4 and F4G are reported, the greater of the two results must be used in any application of the CWS PHC guidelines and the gravimetric heavy hydrocarbons cannot be added to the C6 to C50 hydrocarbons. In samples where BTEX and F1 were analyzed , F1-BTEX represents a value where the sum of Benzene, Toluene, Ethylbenzene and total Xylenes has been subtracted from F1.

In samples where PAHs, F2 and F3 were analyzed, F2-Naphth represents the result where Naphthalene has been subtracted from F2. F3-PAH represents a result where the sum of Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Dibenzo(a,h)anthracene, Fluoranthene, Indeno(1,2,3-cd)pyrene, Phenanthrene, and Pyrene has been subtracted from F3.

Unless otherwise qualified, the following quality control criteria have been met for the F1 hydrocarbon range: 1. All extraction and analysis holding times were met. 2. Instrument performance showing response factors for C6 and C10 within 30% of the response factor for toluene. 3. Linearity of gasoline response within 15% throughout the calibration range.

Unless otherwise qualified, the following quality control criteria have been met for the F2-F4 hydrocarbon ranges: 1. All extraction and analysis holding times were met. 2. Instrument performance showing C10, C16 and C34 response factors within 10% of their average. 3. Instrument performance showing the C50 response factor within 30% of the average of the C10, C16 and C34 response factors. 4. Linearity of diesel or motor oil response within 15% throughout the calibration range. F1-HS-511-WT Soil F1-O.Reg 153/04 (July 2011) E3398/CCME TIER 1-HS

F2-F4-511-WT Soil F2-F4-O.Reg 153/04 (July 2011) CCME Tier 1

Petroleum Hydrocarbons (F2-F4 fractions) are extracted from soil with 1:1 hexane:acetone using a rotary extractor. Extracts are treated with silica gel to remove polar organic interferences. F2, F3, & F4 are analyzed by GC-FID. F4G-sg is analyzed gravimetrically.

Notes: 1. F2 (C10-C16): Sum of all hydrocarbons that elute between nC10 and nC16. 2. F3 (C16-C34): Sum of all hydrocarbons that elute between nC16 and nC34. 3. F4 (C34-C50): Sum of all hydrocarbons that elute between nC34 and nC50. 4. F4G: Gravimetric Heavy Hydrocarbons 5. F4G-sg: Gravimetric Heavy Hydrocarbons (F4G) after silica gel treatment. 6. Where both F4 (C34-C50) and F4G-sg are reported for a sample, the larger of the two values is used for comparison against the relevant CCME guideline for F4. 7. F4G-sg cannot be added to the C6 to C50 hydrocarbon results to obtain an estimate of total extractable hydrocarbons. 8. This method is validated for use. 9. Data from analysis of validation and quality control samples is available upon request. 10. Reported results are expressed as milligrams per dry kilogram, unless otherwise indicated.

MET-200.2-CCMS-WT Soil Metals in Soil by CRC ICPMS EPA 200.2/6020B (mod)

Soil/sediment is dried, disaggregated, and sieved (2 mm). For tests intended to support Ontario regulations, the <2mm fraction is ground to pass through a 0.355 mm sieve. Strong Acid Leachable Metals in the <2mm fraction are solubilized by heated digestion with nitric and hydrochloric acids. Instrumental analysis is by Collision / Reaction Cell ICPMS.

Limitations: This method is intended to liberate environmentally available metals. Silicate minerals are not solubilized. Some metals may be only partially recovered (matrix dependent), including Al, Ba, Be, Cr, S, Sr, Ti, Tl, V, W, and Zr. Elemental Sulfur may be poorly recovered by this method. Volatile forms of sulfur (e.g. sulfide, H2S) may be excluded if lost during sampling, storage, or digestion.

WT ALS ENVIRONMENTAL - WATERLOO, ONTARIO, CANADA GLOSSARY OF REPORT TERMS

Surrogates are compounds that are similar in behaviour to target analyte(s), but that do not normally occur in environmental samples. For applicable tests, surrogates are added to samples prior to analysis as a check on recovery. In reports that display the D.L. column, laboratory objectives for surrogates are listed there. mg/kg - milligrams per kilogram based on dry weight of sample mg/kg wwt - milligrams per kilogram based on wet weight of sample mg/kg lwt - milligrams per kilogram based on lipid-adjusted weight mg/L - unit of concentration based on volume, parts per million. < - Less than. D.L. - The reporting limit. N/A - Result not available. Refer to qualifier code and definition for explanation.

Test results reported relate only to the samples as received by the laboratory. UNLESS OTHERWISE STATED, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION. Analytical results in unsigned test reports with the DRAFT watermark are subject to change, pending final QC review.

Application of guidelines is provided "as is" without warranty of any kind, either expressed or implied, including, but not limited to, fitness for a particular purpose, or non-infringement. ALS assumes no responsibility for errors or omissions in the information. Guideline limits are not adjusted for the hardness, pH or temperature of the sample (the most conservative values are used). Measurement uncertainty is not applied to test results prior to comparison with specified criteria values. Quality Control Report

Sample Parameter Qualifier key listed: Qualifier Description

DLQ Detection Limit raised due to co-eluting interference. GCMS qualifier ion ratio did not meet acceptance criteria. DLVH Detection Limit raised due to interference from Volatile Hydrocarbons on VOC method. Chromatographic elution of interfering peaks in the same region as test analytes prevents a determination of whether VOC analyte is present or absent (above/below regular detection limits). OWP Organic water sample contained visible sediment (must be included as part of analysis). Measured concentrations of organic substances in water can be biased high due to presence of sediment. DLHC Detection Limit Raised: Dilution required due to high concentration of test analyte(s).

Analytical methods used for analysis of CCME Petroleum Hydrocarbons have been validated and comply with the Reference Method for the CWS PHC.

In cases where results for both F4 and F4G are reported, the greater of the two results must be used in any application of the CWS PHC guidelines and the gravimetric heavy hydrocarbons cannot be added to the C6 to C50 hydrocarbons. In samples where BTEX and F1 were analyzed , F1-BTEX represents a value where the sum of Benzene, Toluene, Ethylbenzene and total Xylenes has been subtracted from F1.

In samples where PAHs, F2 and F3 were analyzed, F2-Naphth represents the result where Naphthalene has been subtracted from F2. F3-PAH represents a result where the sum of Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Dibenzo(a,h)anthracene, Fluoranthene, Indeno(1,2,3-cd)pyrene, Phenanthrene, and Pyrene has been subtracted from F3.

Unless otherwise qualified, the following quality control criteria have been met for the F1 hydrocarbon range: 1. All extraction and analysis holding times were met. 2. Instrument performance showing response factors for C6 and C10 within 30% of the response factor for toluene. 3. Linearity of gasoline response within 15% throughout the calibration range.

Unless otherwise qualified, the following quality control criteria have been met for the F2-F4 hydrocarbon ranges: 1. All extraction and analysis holding times were met. 2. Instrument performance showing C10, C16 and C34 response factors within 10% of their average. 3. Instrument performance showing the C50 response factor within 30% of the average of the C10, C16 and C34 response factors. 4.

WT ALS ENVIRONMENTAL - WATERLOO, ONTARIO, CANADA GLOSSARY OF REPORT TERMS

Surrogates are compounds that are similar in behaviour to target analyte(s), but that do not normally occur in environmental samples. For applicable tests, surrogates are added to samples prior to analysis as a check on recovery. In reports that display the D.L. column, laboratory objectives for surrogates are listed there. mg/kg - milligrams per kilogram based on dry weight of sample mg/kg wwt - milligrams per kilogram based on wet weight of sample mg/kg lwt - milligrams per kilogram based on lipid-adjusted weight mg/L - unit of concentration based on volume, parts per million. < - Less than. D.L. - The reporting limit. N/A - Result not available. Refer to qualifier code and definition for explanation.

Test results reported relate only to the samples as received by the laboratory. UNLESS OTHERWISE STATED, ALL SAMPLES WERE RECEIVED IN ACCEPTABLE CONDITION. Analytical results in unsigned test reports with the DRAFT watermark are subject to change, pending final QC review.

Application of guidelines is provided "as is" without warranty of any kind, either expressed or implied, including, but not limited to, fitness for a particular purpose, or non-infringement. ALS assumes no responsibility for errors or omissions in the information. Guideline limits are not adjusted for the hardness, pH or temperature of the sample (the most conservative values are used). Measurement uncertainty is not applied to test results prior to comparison with specified criteria values. Quality Control Report
