1   INTRODUCTION
    ECOH Management Inc. (ECOH) was retained by Lambton Kent District School Board
    (The Board) to:
       1. Conduct an independent and impartial assessment of the current concerns in relation
          to the potential presence of toxic mould or other toxic substances at Ridgetown
          Public School in Ridgetown, Ontario;
       2. Provide a written report setting out its findings with respect to the presence of toxic
          mould and/or other toxic substances; and
       3. Recommend any necessary remediation.

    The following report includes a description of the assessment methodologies, discussion and
    conclusions of the investigation findings, sampling results, and recommendations regarding
    any further action required. Mr. Rob Fernandes and Ms. Drew Iverson of ECOH conducted
    the fieldwork on January 16 and 17, 2008. Ms. Drew Iverson returned on January 25, 2008
    to collect air samples for mould. Mr. Rob Fernandes and a remediation contractor (CIS)
    revisited the school on January 26, 2008 to conduct further intrusive fieldwork.

2   SCOPE OF WORK
    The following scope of work and investigation strategy was followed:
       • Meeting with the stake-holders,
       • Review of building history,
       • Visual and intrusive inspection of readily-accessible surfaces in the facility,
       • Collection of air and bulk samples for mould, and
       • Preparation of a detailed report.

3   STAKEHOLDERS
    Om Malik, Rob Fernandes, Nax Nagalingam, and Drew Iverson of ECOH held an open
    meeting with the various stakeholders at the school on January 14, 2008. The stakeholders
    present at the meeting provided some building history with respect to health concerns, water
    damage and mould issues. ECOH personnel provided some basic information regarding
    mould hazards in the indoor environment and briefed the stakeholders on ECOH’s scope of
    work at the school.

4   BUILDING DETAILS AND HISTORY

    The main school building was erected in 1950 and a two-room addition was constructed on the
    west side at a later date (referred to as “the Portapac” by building occupants). The library was
    also constructed after the original building.

    The original building is a one-storey, wood framed structure with exterior, load-bearing,
    concrete block walls. Interior dividing walls are composed of terracotta clay blocks. The walls
    are finished on the interior with a plaster skim coat directly over the concrete or terracotta
    blocks. Around the windows, the concrete blocks have been removed and a wood frame
    structure has been installed. On the interior, the area around the windows has been finished
    with drywall; on the exterior, the area has been covered with corrugated metal cladding.

    Ceilings in the original building are a combination of lay-in and glue-on ceiling tiles over
    drywall. The roof of the building was replaced with a new vinyl roof in the summer of 2007
    and the exposed wood roof deck was reportedly cleaned and/or treated with a mould-inhibiting
    solution and some sections replaced at that time.

    The Portapac has a construction similar to that around the windows in the original building:
    interior walls are finished with drywall over wood frame and corrugated metal cladding is
    present on the exterior. The roof is a shingled, pitched roof with wood trusses.

    The library has a corrugated metal deck covered by lay-in ceiling tiles. The interior walls are
    finished with wood panelling and gypsum board.

    The classrooms are heated by radiators located along the exterior walls. Service tunnels
    housing steam pipes for the radiators are present under the floor throughout the main building.

    With a few exceptions, there are no active ventilators in the classrooms. The only source of
    fresh air into the classrooms is passively via the windows. The exceptions include exhaust fans
    in room 9, room 14, and room 15, and an exhaust system to move air through the service
    tunnels and maintain the tunnels under negative pressure relative to occupied areas of the
    building. In addition, window-mounted air-conditioning units are located in the Principal’s
    office, the staff room and the computer room, and an above-ceiling HVAC unit services the
    library.

    Previous water and mould issues were reported in the closets of many classrooms. One of the
    participants described one such leakage as “raining in the closet”. Plumbing systems,
    including domestic hot and cold water pipes, rainwater drains, and steam heating pipes, run
    through the closets. Mould remediations were reportedly conducted in classroom 9 and
    classroom 14.

5     STAFF CONCERNS

      Staff alleged that the JHSC formed under Sec 9 of the OHSA is not taken seriously and
      apparently there had been an investigation by the Ministry of Labour regarding this issue.

      One of the teachers complained of being out of breath “while being exposed”. Another teacher
      wondered if mould exposure had anything to do with her having bouts of cold once every
      month since September 2007.

      One of the teachers just enquired if there was any risk to her or her foetus because she was
      pregnant.

      Although not many staff met with us, the general feeling amongst those we spoke to was that
      in large part the ‘problems’ have been fixed and as such there were no concerns.

6     MOULD

      Moulds are forms of fungi found year round outdoors. Outdoors, moulds live in the soil, on
      plants, and on dead or decaying matter. Mould growth is encouraged by warm and humid
      conditions, although it can also grow during cold weather. Most fungi, including moulds,
      produce microscopic cells called “spores” that spread easily through the air. Live spores act
      like seeds, forming new mould growths (colonies) under the right conditions. Mould requires
      moisture to grow and therefore incidents of water damage, high humidity, or dampness can
      promote mould to grow indoors. Common sources of indoor moisture that cause mould
      growth include flooding, roof and plumbing leaks, damp basements or crawl spaces, or any
      moisture condensation on cold surfaces. (1)

      There are thousands of species of mould and they can be any colour. To be certain that a
      visible growth is in fact mould and to identify different species, a trained mycologist has to
      examine a sample under the microscope. In many instances, mould can be detected by human
      olfactory senses and is often described as a musty odour.

      Most people have no reaction when exposed to moulds. Some individuals can have allergic
      reactions, similar to common pollen or animal allergies. Irritation is the most common health
      effects for individuals sensitive to moulds.

      Moulds are also known to cause infections amongst the vulnerable people. Most vulnerable
      include people with compromised immune systems such as those suffering from HIV, HEP C
      or those undergoing organ transplants. In general pregnant women are relatively more
      vulnerable to suffer health effects of mould, however there is little known evidence of harmful
      effects on the foetus. In addition, moulds may also aggravate asthma.

      Guidance in interpreting the findings of mould investigations is provided by a number of
      documents published by various jurisdictions and organizations, including Health Canada,
      Ontario Ministry of Health, the American Industrial Hygiene Association (AIHA), American
      Conference of Governmental Industrial Hygienists (ACGIH), the Canadian Construction
      Association (CCA) and others. A general consensus opinion exists regarding the need to
      remediate mould growth and conditions conducive to mould growth. The Health Canada
      Guide (2) (1995 version) states that:

      “identifiable promoters of fungal growth require correction, and any visible fungi require
      removal”.

      There are several documents, which provide guidelines for the remediation of mould,
      commonly referred to as the ‘Mould remediation Protocols’. Some of the important ones are:
      The Health Canada Guides, the New York City department of Health Guidelines, The Mould
      guidelines published by the Environmental Abatement Council of Ontario (EACO), Mould
      guidelines recommended by Canadian Construction Association (CCA). The guiding
      principles in all the protocols and guidelines outlines that no procedure contributes to further
      fungal contamination minimizing health risks to building occupants and remediation workers.
      The stringency of controls is grouped into different ‘Levels’ based on the extent of mould
      infestation and other relevant factors.

7     ASSESSMENT METHODOLOGY

      The assessment was conducted in accordance with standard industry practice as set out in the
      CCA “Mould Guidelines for the Canadian Construction Industry” for a visual assessment and
      those in the IICRC standard S520 and the EACO guideline (2004). Although there are no
      regulatory requirements or guidelines in Ontario for such an assessment, the strategy
      recommended in the CCA has been accepted as the industry standard by most experts,
      consultants, and the Ontario Ministry of Labour. The investigation performed was generally
      non-intrusive in nature (i.e. did not include demolition of building systems to verify concealed
      conditions except for several test cuts into walls and ceilings).

      The investigation included a visual inspection, moisture measurements, tape-lift sampling of
      suspect mould growth, and air sampling for viable and non-viable mould. The visual
      assessment in large part consists of visually identifiable mould growth and sources of moisture
      infiltration that would normally promote mould growth on cellulose containing building
      materials.
7.1 Moisture Measurements

      As mould requires moisture and a food source (i.e. drywall, wood, etc.) to grow, moisture
      measurements were obtained to determine areas of potential mould growth. Moisture
      measurements were made using a ‘Protimeter Surveymaster’ electronic moisture meter

    (scanning and penetrating type) at several suspect locations or areas of concern. Elevated
    moisture measurements are those exceeding a reading of 170 on a relative scale or
    exceeding 15% moisture content for wood commonly referred to as the ‘wood moisture
    equivalent’.
7.2 Bulk Sampling for Mould (Tape-Lift Sampling)

    Four (4) tape-lift samples were taken for the identification of mould from representative
    stained/discoloured sections of suspect materials in the subject building. Each tape-lift sample
    was taken by pressing a piece of clean and transparent adhesive tape onto the suspected area
    and removing a part of the suspect material. The tape was then placed/sealed in a labelled
    clean plastic sampling bag and sent to an accredited laboratory for analysis by microscopic
    examination.
7.3 Spore-trap Air Sampling for Mould

    A total of twelve (12) air samples (spore-trap), including a field blank, were collected using a
    high flow QuickTake®15 with Air-O-Cell® sampling cassettes. This method allows the
    collection of a wide range of airborne aerosols including both viable and non-viable mould
    spores. The flow rate of the pump was set at 15 litres per minute with a sampling time of 5
    minutes for a sample volume of 75 litres. Outdoor reference samples were collected along with
    air samples from areas/rooms of concern within the school. After sampling, the cassettes were
    sent to an independent environmental microbiology laboratory, for analysis. The cassettes
    were analysed by microscopic examination.
7.4 Andersen (N6) Air Sampling for Mould

    As fungal infections are typically associated with specific species of mould, one set of samples
    was collected and submitted for culturing analysis to allow speciation. Andersen (N6) samples
    for viable airborne mould were collected concurrently in the same locations as the spore-trap
    samples. Outdoor samples were collected for reference purposes, as was a field blank (for a
    total of 12 samples). A constant high-flow pump, calibrated to a flow rate of 28.3
    litres/minute and connected to the Andersen N6 sampler unit, was used to collect the samples.
    The sampling duration for all of the samples was 5 minutes. The sampler unit was
    decontaminated with alcohol wipes between samples to prevent cross-contamination of the
    samples. This technique utilizes the collection of airborne mould onto a Petri dish containing
    agar media to allow the culturing of the mould spores. The samples collected by this technique
    are generally cultured for a period of approximately two weeks and the moulds are then
    identified to the species level. Results from such results are useful for identification of active
    mould growth or amplification sites, for health risk assessment, and in discovering hidden
    mould growth. In interpreting the results from the Andersen N6 technique outlined above, it is
    to be recognized that only the viable spores are counted.
7.5 Analyses

    The tape-lift and air samples were analyzed by EMC Scientific Inc., an independent
    environmental microbiology laboratory that participates in the American Industrial Hygiene

8   FINDINGS

        A visual inspection of the entire school was carried out to identify:
           •   Any visible mould (interior inspection),
           •   Conditions that may suggest possible source of moisture infiltration (exterior
               inspection), and
           •   Other significant observations that may have an adverse impact on the indoor air
               quality.
8.1 Interior Inspection

8.1.1      Confirmed Mould Growth or Other Air Quality Issues
           •   As previously reported (see the letter report regarding the Ridgetown Public School
               staff room, dated November 16, 2007), moderate mould was observed in the staff
               room on the drywall ceiling above the ceiling tiles (a few square feet in total area)
               along the edge of the ceiling against the plaster wall. Mould growth was also present
               on the back of the wood panelling and the underlying plaster on the east wall.
               A test cut made into the damaged drywall ceiling revealed some minor staining and
               mould growth on the wood roof joists and roof planks.
           •   Minor mould growth (approximately 1 square foot) was observed on the wood
               panels and frame inside the service tunnel access in the closet in classroom 9.
           •   Moderate mould growth (a few square feet in total area) was observed on the wood
               frame inside the bulkhead surrounding the domestic water pipes in the closet in the
               Staff Work Room (a.k.a. classroom 5, Ontario early years room).
           •   Minor mould growth (approximately ½ square foot) is present between the layers of
               wood on the door (top left corner) to the closet in classroom 7. Minor mould growth
               was also observed on the plaster wall inside the closet and some of the wood located
               above the ceiling. The source of water appeared to be the rainwater drain in the
               corner of the closet near the door. Other affected materials include a stained ceiling
               tile in the cloak room by the door, black staining on the floor and the wall near the
               base of the pipe and plaster damage to the wall inside the closet. On the other side of
               the wall (in the corridor), the plaster was damaged and water marks were observed
               on a corkboard mounted on the wall. Mould growth was not observed on any
               materials on the corridor-side of the wall.
           •   Minor mould growth (a few square inches in each location) and dark water staining
               were observed on the back of the wood trim below the windows in the library at
               floor-level (i.e. bottom of wood panelling).
           •   Minor mould growth was observed between layers of wood on the front door of the
               cabinet under the sink in classroom 4.

        •   Minor mould growth was observed on a book on the desk in the library office during
            the initial assessment. When ECOH returned to conduct air sampling, the book was
            no longer on the desk in the library office.
        •   Approximately one (1) square inch of suspect mould growth was observed on
            cellulose ceiling tiles in classroom 13. The affected ceiling tiles were removed and
            disposed of by CIS during the intrusive investigation. The underlying materials had
            no signs of moisture damage or mould growth.
        •   Ventilation/exhaust systems were only observed in three classrooms (classrooms 9,
            14, and 15). In classrooms where exhaust fans were present, the fans are too loud to
            be operated while classes are being conducted. In addition, the location of the fans
            may be such that fresh air is not being drawn into the room.
        •   The exhaust system connected to the service tunnels below the classrooms appeared
            to generate good negative pressure such that any mould, odours, or other
            contaminants that may be present in the tunnels should not negatively impact the air
            quality in occupied areas of the building.
        •   Mouse droppings and a chewed plastic bag were observed on the floor in the
            kindergarten storage closet.
        •   Photocopiers and printers were observed in the supply room and the computer room.
            Laser printers and photocopiers may be sources of particulates and ozone, which
            may be harmful to occupants during extended periods of use. Ventilation systems
            designed to remove the hazards (i.e. exhaust fans) were not present in either
            location.
8.1.2   Water Damage and Evidence of Moisture Intrusions

        •   Wood shelving and coat racks (for storing shoes, boots, coats, hats, etc.) are present
            in the corridors and cloak rooms throughout the school. The shelves have dark and
            light water stains on the top and bottom surfaces. Two tape lift samples (12040-
            RTP-TL-04 and 12040-RTP-TL-07) were collected from the stained areas and
            laboratory analysis determined that mould growth was not present (see section 9.1).
        •   Window ledges are absent under the windows in classrooms 14 and 15, and wooden
            shelving units are present directly under the windows. Water stains, consistent with
            the stains on the coat racks and shelves in the corridor, were observed on the top of
            the shelving units.
        •   Wooden window ledges and shelves are present on the exterior walls in classrooms
            throughout the north wing. Water stains, consistent with the stains on the coat racks
            and shelves in the corridor, were observed on the top of the ledges and shelves in the

           the kitchen. Some dark water staining, consistent with the stains on the bottom of the
           cabinet under the sink in classroom 15, was noted in the wood cabinets under and
           over many of the sinks. A tape lift sample (12040-RTP-TL-06) was collected from
           the stained area and laboratory analysis determined that mould growth was not
           present.
       •   Plaster damage was observed in various locations throughout the school. Cracks in
           the plaster were commonly observed above bulletin boards and chalkboards, in the
           closets and cloak rooms, along the wall under the windows and in the corners near
           the tops of the windows. Mould growth was not observed on the exterior surface of
           the walls. Intrusive investigation in several representative locations indicated that the
           materials behind the plaster were dry and free from mould growth.
       •   Aluminium-covered cork panels are present above the south windows in the library.
           The aluminium on the exterior side of the panels was in good condition. On the
           interior side, the ECOH inspectors pulled the aluminium away from the cork,
           revealing minor water staining but no mould growth.
       •   The wood trim above the south windows in the library was water-stained. This
           corresponds with wood trim under the facia on the exterior side of the wall, which
           was similarly stained. The trim was pulled back and no mould growth was observed
           in the area.
       •   The drywall around the windows in many classrooms was cracked in the bottom
           corners. Intrusive investigation in several representative locations indicated that the
           back side of the drywall, as well as the materials behind the drywall, were dry and
           free from mould growth.
       •   Part of the drywall ceiling in classroom 14 near the exterior wall appears to have
           been repaired or replaced (possibly as part of the mould remediation noted in section
           4 above). Investigation of the attic space above the room did not identify any
           evidence of leakage issues at the time of the assessment.
       •   The bottom of the wood panelling on the east wall of the principal’s office was
           warped and water stained. This corresponds with the water damage observed on the
           other side of the wall in the staff room. Mould growth was not observed on or
           behind the panelling in the principal’s office.
       •   The floor of the principal’s office is carpeted. Although no mould growth or staining
           was observed, carpets are known to be potential reservoirs for mould spores.
       •   Carpet and wood were observed in front of the door in the exterior wall in the boy’s
           and girl’s washrooms, and in the kindergarten cloak room. The wood and carpet
           appeared to be filling in an area where a grate was previously present. Dark water
           stains, consistent with those observed on wood materials in other locations in the
           building, were present on the wood. No mould growth or staining was observed on
           the carpets; however, as noted above, they are known to be potential reservoirs for
           mould spores.

        •   Where visible from the ceiling space, the underside of the roof deck did not exhibit
            signs of significant mould growth (with the aforementioned exception of the staff
            room).
        •   In addition to the water damage noted above, evidence of roof leaks, mechanical
            leaks, or condensation was noted in various areas throughout the building.
            Specifically, evidence of water intrusions was noted in the following locations and
            forms:
            o Water marks were observed on the wood trim on the ceiling running alongside
              the north (exterior) wall of the computer lab (classroom 10);
            o Water marks were observed on the plaster walls in various locations throughout
              the building;
            o Dark water stains were observed on the bottom of the cabinet beside the radiator
              in classroom 14;
            o A dark water stain was observed on the fabric covering the speaker box on the
              east wall in classroom 12;
            o Water marks were observed on the wood trim above the bulletin board in
              classrooms 9 and 11;
            o A water-stained cardboard box was observed under the sink in classroom 11 and
              on the shelf in the supply room;
            o Water marks were observed on wood trim above the door near the ceiling
              outside the office;
            o Water stains were observed on the stacked vertical supports under the stage in
              the gym.
            o Water stains were observed on rainwater drain insulation in the gym.
            o Stained drywall was noted at a damaged area of ceiling above the lay-in ceiling
              tiles in the corridor outside of Classroom 8. A new section of plywood roof
              sheathing was noted above the affected area suggesting that the damage was
              historical in nature.
            Mould growth was not observed at any of the above-noted locations.
8.1.3   Concerns for Future Water Damage and Moisture Intrusion

        •   Wood shelving units, bulletin boards and chalkboards are mounted directly (i.e.
            without an air gap) on interior and exterior walls throughout the school. Although
            water marks were observed on the wood trim around the boards in some locations,
            no water staining, warping, or mould growth were observed in any location.
        •   There is evidence that the chalkboards are washed with water. Although water marks
            were observed, no water staining, warping, or mould growth were observed in any
            location.

       •   The sanitary vents for the sinks in the Ridgekids classrooms are connected to the
           roof drains which may represent a potential risk for backed-up sinks as a result of
           heavy precipitation and/or accumulation of debris in the sanitary pipes.
8.2 Exterior Inspection:

    Evidence of damage to the exterior envelope and roof of the building (potential routes for
    moisture infiltration) was noted as the following:
      •    The aluminium cladding present around the windows throughout the school, and on
           the entire exterior of the Portapac, is rough cut and not caulked. In addition, open
           screw holes and bent areas are present in the metal cladding in various locations.
           These areas could be a route for moisture to enter. As the underlying materials are
           wood and drywall, mould growth may result if the materials get wet. Intrusive
           investigation in several representative locations indicated that the materials behind
           the cladding were dry and free from mould growth at the time of the assessment.
      •    Missing or inadequate caulking was observed along the exterior of the building in the
           following areas:
            o Around the pipes penetrating the north wall of the mechanical room;
            o Around the cable penetrating the south wall of the north corridor;
            o Between bricks in the masonry of the north wall.
      •    Pieces of brick were missing in three locations on the west wall of the south corridor.
           Two of these were located midway down the wall; the third was directly under the
           facia. These may be a route of entry for pests (e.g. insects, rodents), as well as
           moisture.
      •    The asphalt has separated from the base of the wall in several locations, one of which
           is the south wall of the north corridor (outside classroom 12). Additionally, in this
           area the ground slopes towards the foundation. Water may pool in the gap between
           the asphalt and the building and enter the service tunnels through the foundation.
      •    As previously noted, aluminium-covered cork panels are present above the windows
           on the south side of the library. Although the panels were in good condition at the
           time of the survey, if the exterior surface of the panels is damaged, water infiltration
           may result in mould growth on the underlying cork.
      •    While weep holes were observed along the base of the wall, they were not observed
           above the windows and doorways throughout the school. Their absence creates a
           potential for moisture retention along the walls.
      •    The vinyl roof of the school appeared to be in good condition overall. Significant
           water accumulation was noted on the roof of the south wing. Red algae growth was
           observed in pooled water on the roof of the north wing. As there are no air intake
           vents in close proximity to the algae, a health hazard is unlikely.

       •    Damaged flashing was noted on the roof of the Portapac on the edge were it joins the
            main school (the southwest corner of the roof). Investigation of the ceiling space
            below the damaged flashing indicated that the materials below were dry and
            undamaged at the time of the assessment.

9   SAMPLING RESULTS
9.1 Bulk samples

    The results of microscopic analyses for the bulk (tape-lift) samples collected from
    representative stained or discoloured sections of suspect materials in various areas of the
    school are presented in the Laboratory Analytical Reports in Appendix A. This Appendix
    also identifies the location of the sample, whether the sample represents a mould growth and
    the type of mould identified.

    Previously, three tape lift samples were collected during the assessment of the staff room on
    November 16, 2007. Four additional tape lift samples were collected during the January
    assessments.

    Three (3) samples were collected from areas that were representative of water stains on
    wood surfaces, a condition that was present throughout the building. One sample was
    collected from the darkly stained area on the top surface of the wood shelf in the corridor
    between classrooms 14 and 15 (12040-RTP-TL-04); a second sample was collected from a
    similar darkly stained area on the bottom of the cabinet in classroom 15 (12040-RTP-TL-
    06); a third sample was collected from a lightly stained area on the underside of the shoe
    rack in the kindergarten room (12040-RTP-TL-07).

    Laboratory analysis determined that mould growth was not present at any of the sampled
    locations. Similar staining was observed on wood surfaces in various locations throughout
    the school. Although mould growth cannot be ruled out in any location without analysis of a
    tape lift sample, the results of the collected samples can be extrapolated to similarly stained
    areas. As such, stains consistent with those noted above are not thought to be mould growth.

    The remaining four (4) tape lift samples were collected from areas with a unique condition
    (i.e. similarly stained or damaged areas were not observed in other areas of the facility).
    Analysis of these tape-lift samples confirmed the presence of various types of mould growth
    in 3 of the 4 samples. The tape lift samples identified mould growth in the following
    locations:
        •   In the staff room, on the drywall ceiling above the ceiling tiles along the edge of the
            ceiling against the plaster wall.
        •   In the staff room, on the back of the wood panelling on the east wall and on the
            underlying plaster.
        •   In classroom 4, between layers of wood on the front door of the cabinet under the
            sink.

    Four (4) mould genera were identified. They are:

    1. Aspergillus,

    2. Chaetomium,

    3. Penicillium, and

    4. Tritirachium.
    Aspergillus is a ubiquitous fungus found in nature. It is commonly isolated from soil, plant
    debris, and found within the air of indoor environments. The genus Aspergillus includes
    over 185 species. Around 20 species have so far been reported as causative agents of
    opportunistic infections in man.
    Chaetomium is commonly found on deteriorating wood products, emits a musty odour and
    is frequently found on water-damaged drywall and other lower cost construction products.
    Chaetomium species are among the fungi causing infections and cutaneous (skin) lesions.
    The members of the genus Penicillium are widespread and are found in soil, decaying
    vegetation, and the air. They are commonly considered as contaminants but may cause
    infections, particularly in immuno-compromised hosts. In addition to their infectious
    potential, they are known to produce mycotoxins.
    Tritirachium are common and may be found in soil and decaying plant material. Indoors,
    they may be found on paper, textiles, adhesives and drywall. Information regarding the
    toxicity and allergenicity of this mould type is very limited. Reported health effects include
    corneal ulcers and otomycosis.
9.2 Air Samples

    A total of twenty four (24) air samples were collected including four outdoor samples and
    two trip blanks. Of these, twelve (12) samples were collected using the Air-O-Cell
    technique while the other twelve (12) samples were collected on an agar medium (MEA)
    using N-6 Anderson method for subsequent culturing. Results of analysis of the air samples
    are summarized in the Laboratory Analysis Reports in Appendix A.

    The laboratory reports show the location of each sample, the type of mould identified (to the
    genus or species level), the calculated number of spores of each mould type and the total
    number of mould spores per cubic metre of air.

    A review of the analytical results shows that, in large part, the indoor fungal ecology
    (different mould types) is very similar to the outdoor fungal ecology. Although the spore
    concentrations identified in the subject area were slightly greater than those found in the
    outdoor reference samples, the types of spores are reasonably similar to those identified
    outdoors and are relatively consistent throughout the building. Strict comparisons between
    the indoor and outdoor fungal ecology during the winter season are difficult due to the low
    concentrations of mould typically found as a result of the weather conditions (i.e.

    precipitation/snow cover). The spore levels present in the school building during the
    sampling are not unusual and are consistent with those that are typically identified in similar
    buildings. The air sampling results do not suggest that the indoor air quality is significantly
    impacted adversely by the presence of indoor mould amplification sites and/or
    contamination, and suggest instead as a result of inherent settled spores in dust circulated by
    people and air flow.

    It should be noted that the air samples with relatively high spore concentrations (when
    compared to the other samples within the school) were taken in classrooms with students
    present (12040-RTP-AOC-07 in classroom 9, and 12040-RTP-AOC-10 in classroom 13); all
    other air samples were taken in rooms that were not occupied at the time of sampling.

    Although spore concentrations in classroom 9 (a location in which mould was previously a
    concern) were high compared to other areas of the school, the source of the spores is not
    judged to be mould growth present in the room. Mould was identified on the wood frame
    inside the service tunnel access in the closet in classroom 9 but because the service tunnels
    are under substantial negative pressure, and the tunnel access is covered with a solid panel,
    it is unlikely that the mould on the wood frame is affecting the air in the classroom. Instead,
    the elevated spore levels are thought to be a result of increased air movement in the
    classroom, causing settled spores to become airborne at the time of the sampling.

    As there is no active form of ventilation in the classrooms, air movement caused by people
    moving, breathing and talking in a classroom may impact the overall airborne dust and
    mould spore levels in the room.

    Elevated levels of non-fungal material (i.e. dust) were identified in many of the indoor
    samples. High dust levels may impact the indoor air quality and affect occupant comfort.

    Whereas all the mould species identified in the samples are known allergens and have been
    implicated in different types of infections, they are generally all common outdoor species
    and the concentration of any one individual species within occupied areas of the building
    does not exceed the common guidelines put forward either by Health Canada or the
    American Industrial Hygiene Association, IICRC or the New York City Protocol. In other
    words, the air sampling results do not suggest that there is a significant health hazard due to
    airborne mould in various parts of the school.

10 DISCUSSION AND CONCLUSIONS

    The presence of mould growth in the school was visually determined and confirmed by
    laboratory tests.

    The mould growth present on the various materials in classrooms 5, 7, and 9 is judged to be
    the result of mechanical pipe leaks. The water damage in classrooms 5 and 9 appeared to
    have been from either domestic water pipes or hot water heating pipes. The damage in
    classroom 7 is thought to be from the rainwater drain adjacent to the closet door. All mould-

    affected building materials should be removed following applicable guidelines. As it cannot
    be conclusively determined if the moisture infiltration is current or historical, it is important
    to remove water affected building materials to determine if there are any current moisture
    infiltrations/leaks.

    Mould growth was also confirmed in the staff room, on the drywall ceiling above the ceiling
    tiles, on the back of the wood panelling and on the underlying plaster on the east wall. As
    previously reported, the water intrusion that caused the mould is thought to have originated
    at the ceiling and likely came through the roof. As the roof was replaced recently, the water
    intrusion is likely historical in nature.

    The mould and water damage to the wood cabinet door under the sink in classroom 4 is
    likely a result of water from the sink basin or sink usage spilling over the edge of the
    counter. Although the materials were dry at the time of the assessment, the damage and
    mould growth suggest that this has been a repeated problem. This area and similar areas
    may be sites of continued and future mould growth if the water spills from the sink onto the
    cabinet.

    The mould growth below the windows (i.e. damage to wood paneling) in the library is
    thought to be due to water entering through the edges of the windows and/or from windows
    being left open during precipitation events. There is also evidence that water historically
    entered through the roof above the south library windows, which may have contributed to
    the mould growth in this area. If the windows are not adequately caulked and closed during
    precipitation, these areas may be sites of continued and future mould growth.
    In the body of the report we have listed several possible routes of moisture infiltration;
    however, this does not imply that there are no other deficiencies in the building envelope
    that may contribute to moisture infiltration.
    Whereas these noted deficiencies should be rectified as soon as possible, based on our
    observations and analysis of air sampling data it is concluded that a significant and
    immediate health hazard due to mould is unlikely. As such it is recommended that the
    recommended actions detailed below should be implemented in a planned and coordinated
    fashion

11 RECOMMENDATIONS
    Whereas the idea of a mould free building is not realistic because the ambient air of the
    building will have some quantity of mould spores originating from the outdoor environment,
    all efforts should be directed towards control of moisture, which can support mould growth.
    Any incidents of leakage, flooding, or other water infiltration and any damaged materials
    must be appropriately and immediately addressed to prevent potential mould growth.
    In addition to general recommendations made for other schools detailed in previous reports
    (retaining a consultant to develop a detailed scope of work, developing a mould management
    program, staff training, seeking stakeholder input, communicating results of testing etc.) the
    School Specific Recommendations are as follows:

       1. Remove and dispose of a 2-foot wide section of damaged drywall ceiling along the
          east wall of the staff room following Level II mould remediation procedures as
          outlined in the CCA 2004 Mould Remediation Guidelines. The affected wood
          panelling and baseboards should also be removed, and the underlying plaster wall
          and overlying roof joists and deck should and be cleaned as part of the remediation.

       2. Remove and dispose of (or sand, clean and seal) the wood frame inside the bulkhead
          surrounding the domestic water pipes in the closet in the Staff Work Room (a.k.a.
          classroom 5, Ontario early years room) using Level II mould remediation procedures
          as outlined in the CCA 2004 Mould Remediation Guidelines.

       3. Remove and dispose of (or sand, clean and seal) the wood frame inside the service
          tunnel access in the closet in classroom 9 using Level I mould remediation
          procedures as outlined in the CCA 2004 Mould Remediation Guidelines.

       4. Remove and dispose of the wood door to the closet in classroom 7 using Level I
          mould remediation procedures as outlined in the CCA 2004 Mould Remediation
          Guidelines. Clean the mould growth off of the plaster wall. Other affected materials
          in the vicinity of the rainwater drain, including stained wood above the ceiling a
          stained ceiling tile in the cloak room by the door and black staining on the floor
          should also be removed and/or cleaned.

       5. Remove and dispose of the floor-level wood trim (i.e. bottom 4” of wood paneling)
          below the windows in the library using Level I mould remediation procedures as
          outlined in the CCA 2004 Mould Remediation Guidelines.

       6. Remove and dispose of the front door of the cabinet under the sink in classroom 4
          using Level I mould remediation procedures as outlined in the CCA 2004 Mould
          Remediation Guidelines.

       7. Install appropriate ventilation/exhaust systems in all classrooms to improve the
          indoor air quality. The ventilation/exhaust systems should be designed by an
          engineering firm in collaboration with ECOH or another competent environmental
          consultant. The fans should be quiet enough to run while classes are being
          conducted. A noise-dampening system should be added to the pre-existing fans so
          they can also be operated while the rooms are occupied.

       8. Ventilation systems designed to remove the particulates and ozone produced by laser
          printers and photocopiers should be installed in the supply room and the computer
          room.

       9. Properly clean mouse feces from the floor behind plastic bags in the kindergarten
          storage closet and dispose of any materials that were affected by mouse activity (i.e.
          materials in bags likely entered by mice).

       10. Seal (i.e. varnish) the wood shelves and coat racks in the corridors and cloak rooms
           and re-seal as necessary to prevent moisture damage as a result of the storage of wet
           items. Alternatively, replace the wood shelves and coat racks in the corridors and
           cloak rooms with units made from a non-porous material (e.g. plastic).

       11. Ensure that windows are closed during precipitation to prevent damage to wooden
           window ledges and shelves. Porous classroom materials (e.g. books, paper, artwork,
           etc.) should not be stored on the shelves and ledges under the windows.

       12. Ensure that all joints that require caulking and areas where caulking is missing are
           properly caulked including the following:
           o Around holes and rough cut areas in the metal cladding, along cracks, along
             damaged/missing mortar joints, and around sinks/counters in classrooms
           o Around the pipes penetrating the north wall of the mechanical room;
           o Around the cable penetrating the south wall of the north corridor;
           o Between bricks in the masonry of the north wall and where bricks are missing on
             the west wall of the south corridor.
       13. Remove any water affected building materials (including mechanical insulation,
           cardboard boxes, wood materials, etc.) to determine if there are any current moisture
           infiltrations/leaks.
       14. Install shelving units, bulletin boards and chalkboards with a ½ inch air gap between
           the back surface and the wall to prevent potential mould growth in the event of
           moisture infiltration behind the materials.
       15. Ensure that the chalkboards are thoroughly dried after they are washed with water.
    General Recommendations:

       1. ECOH or another competent environmental consultant should be retained to develop
          a detailed scope of work for proper remediation procedures and to assess any other
          building envelope issues that may allow further moisture infiltration.

       2. The School Board should develop a mould management program to prevent any
          moisture infiltration and to ensure that steps are in place to intervene in a timely
          fashion in the event of a flood or a leak so that mould is not allowed to grow. In
          addition, because many species are known to cause infections amongst vulnerable
          members of the society such as those with immune system deficiency and other pre-
          existing medical conditions, it is imperative that a mould management program has
          provision for early detection and safe removal of any mould that may develop.

       3. Mould assessment training should be given to all custodial staff and a mould
          information session should be arranged for all teaching staff. ECOH will be pleased
          to develop and deliver such a training program.

       4. The results of the present air sampling should be made available for any of the
          affected staff or parents of the affected children so that they can share the results
          with their physicians or allergists as appropriate.

       5. In developing and implementing remedial measures input should be sought from not
          only the professionals but also the staff and other stakeholders. In our experience
          open communication is the first step to resolving mould related concerns and issues.
          A general meeting with the parents of the affected children may be considered as a
          part of the communication tool kit.

Note:
1. Mould growth is subjectively assessed with description terms sparse, moderate and abundant.
2. The presence of spores (lacking other fungal structures associated) is assessed as following: a few spores (< 10 spores average per
   microscopic field at 400X), some spores (10-100 spores average per microscopic field at 400X), many spores (>100 spores average
   per microscopic field at 400X).
3. The presence of a few spores generally represents settled spores on the surface of the sample rather than indicating mould growth.
4. The results are only related to the samples analyzed.

Note:
1. Aspergillus/Penicillium type spores may include those of Acremonium, Paecilomyces, Trichoderma and others.
2. A scale of 0 + to 3 + (indicating increasing amount) is used to rate abundance of fungal fragments and non-fungal material, with 3+ indicating the most abundance.
3. The presence of a large amount of dust debris may obscure some spores to be counted. Spore counts from samples with 3 + non-fungal material
   and/or 3 + fungal material may be treated as under-counts.
4. Unidentified spores are those lacking distinguishable characteristics for correct identification. Colorless are colorless spores lacking distinguishable characteristics.
5. These results are only related to the sample(s) analyzed.

Description:

Ventilation fan is
right in front of the
door to classroom 14.
If air is coming in
through the door, the
system will “short
circuit” and fresh air
will not reach the
occupants of the
room.
Fan is too loud to be
turned on while
classes are being
conducted.
