2. GENERAL BACKGROUND

2.1 Introduction

GlassRatner Advisory & Capital Group, LLC (referred to hereunder as the client), retained Insite
Environmental, LLC (IE) to perform a fungal assessment, specifically related to the Council House
property located at 142 Mitchell Street, SW, Atlanta, GA 30303 (referred to hereunder as subject
property). On Tuesday, February 28, 2012, Mr. Donald Mitchell of IE performed the site
assessment.

The lower level of the subject property underwent fungal remediation activities in January of 2011 in
which clearance criteria was successfully achieved and documented by Insite Environmental, LLC in
the Post-Assessment & Sampling letter dated February 4, 2011. IE has been requested to perform a
reevaluation and appropriate sampling of the previously affected areas of the subject property.

Currently the client is awaiting the results of this review.

2.2 Authorization

The fungal assessment activities were performed at the subject site per the request of Mr. Joel
Murovitz of GlassRatner Advisory & Capital Group, LLC. All project scheduling was approved
through Mr. Joel Murovitz of GlassRatner Advisory & Capital Group, LLC.

2.3 Purpose and Scope

The purpose of this assessment was to conduct a visual inspection of the property and to collect
needed samples in order to determine the presence or absence of fungi on building materials,
excessive particulate matter and/or their impact on the indoor air quality.

The scope of this assessment included visually inspecting the property, collecting samples,
interpreting the laboratory results that were collected and producing a written report of our
findings.

The assessment was executed in accordance with the authorized scope of work. This report is
solely a record of activities, observations, analytical results and recommendations performed to
date.

2.4 Site Description

The property is classified as a commercial/office structure constructed on a poured concrete
slab foundation. Construction materials generally consist of wood, metal framing and concrete
substrates, gypsum drywall materials, suspended ceiling with cellulose ceiling tiles, hardwood,
carpet and tile floor covering. The exterior is concrete, masonry and glass. The total assessed
occupiable locations of the subject property are estimated at approximately ≥ 4,500 ft².




                                                   -4-
                                                                  Project Name: GlassRatner/Council House
                                                                                 Project No. IE-GR142-0212


3. METHODOLOGY

To determine whether the Subject Property has an amplified fungal or particulate situation, IE
inspectors may use a wide variety of testing techniques and technologies to take samples of
possible adverse impact.

3.1 Viable Air Samples
Viable Air Samples are taken via an Anderson N-9 single-stage viable impactor. This type of
sampler imparts viable spores on potato dextrose agar petri dishes placed in the bioaerosol
sampler. After the sampling period, IE routine practice of five minutes, the impacted fungi petri
dishes are incubated in a special incubator that is high in humidity and void of all ambient light;
the impacted fungi petri dishes are incubated at a temperature suitable for fungal growth. The
most accurate mold identification is only possible after seven (7) to ten (10) days of live culturing
for the mold cultures to reach their maximum identification growth. After the incubation period,
the fungal samples are removed and the results recorded.
3.2 Non-viable Air Samples – Spore Trap Device
Spore traps are a unique sampling device designed for the rapid collection and analysis of a
wide range of airborne particulates, including fungal spores. Samples are analyzed via light
microscopy at 600X magnification, with the entire trace (100% of the sample) being analyzed.
The results are reported as total, meaning they include both viable and non-viable fungal
spores. This technique does not allow for the differentiation between Aspergillus and Penicillium
spores. Small (~1-3µ) spherical spore-like structures that cannot be identified and which may
include Aspergillus, Penicillium, Trichoderma or other genera, are grouped together as
Amerospores. Additionally, depending on morphology, other non-distinctive spores will be
reported in categories such as Ascospores (produced in an ascus) or Basidiospores (borne
outside a basidium including the mushrooms and other microfungi). Genera with greater than
500 spores on a slide are difficult to count and are therefore estimations. Similarly, excessive non-
microbial particulates can mask the presence of fungal spores, thereby reducing counting
accuracies.
3.3 Bulk and Surface Samples
Surface and Bulk Samples - Bulk, swab and dust samples undergo an aqueous extraction and
subsequent microscopic analysis. Tape samples are analyzed directly; spores are counted and
characterized. All samples are analyzed via light microscopy at 600X magnification. The results
are reported as total, meaning they include both viable and non-viable fungal spores. This
technique does not allow for the differentiation between Aspergillus and Penicillium spores.
Small (~1-3µ) spherical spore-like structures that cannot be identified and which may include
Aspergillus, Penicillium, Trichoderma or other genera, are grouped together as Amerospores.
Additionally, depending on morphology, other non-distinctive spores will be reported in
categories such as Ascospores (produced in an ascus) or Basidiospores (borne outside a
basidium including the mushrooms and other microfungi).

4. OBSERVATIONS & RESULTS

4.1 Temperature and Relative Humidity (RH%)
An Extech, Oregon Scientific or Springfield Precise Temp Hygrometer/Thermometer was placed
in each area and allowed to record measurements for a short period of time. Measurement and
recording of the air temperature and relative humidity is used to determine the relative
differences in the indoor and outdoor environment.
                 Location                      Temperature         Relative Humidity RH%

 Outdoor Front – Time: 1230 – 02/28/2012           54.3˚F                    87.4%
        Wind – Calm – 0-5 mph
          Weather – Overcast
      Lower Level – Storage Area                   67.1ºF                    44.3%

        Lower Level - Office Area                  62.7ºF                    51.2%

          Lower Level - Hallway                    62.0ºF                    53.8%

 Lower Level – Dr. Robert Wyrick’s Office          68.5ºF                    52.6%


IE recommends maintaining relative humidity levels within an indoor environment at 55% and
below in order to create conditions unfavorable for mold proliferation.

4.2 Visual/Olfactory Observations

Upon entering the assessed areas of the subject property described above, no odor typically
associated with indoor moisture and/or mold occurrence was observed. “Moldy/Musty” odors
are normally associated with the microbial Volatile Organic Compounds (mVOC’s) produced by
active mold growth.

The results of temperature and percent relative humidity measurements taken within the
assessed areas of the subject property indicate conditions that were within established levels by
the American Society of Heating Ventilation and Air Conditioning Engineers as acceptable for
occupancy. Those guidelines suggest maintaining indoor relative humidity levels between 30-
60%RH. Maintaining indoor relative humidity at these levels will generally not promote fungal and
bacterial growth. IE recommends maintaining relative humidity levels within an indoor
environment at 55% and below.

Observations of the assessed areas of the subject indicated no evidence of active water
infiltration or reemergence of fungal staining/growth to the previously remediated substrates.

Non-viable air sampling of the previous work areas at the site was performed at the time of visual re-
assessment. In addition, a request was made to expand the non-viable air sampling outside of the
original work area to include the Lower Level – Hallway and the dental office suite currently occupied
by the tenant, Dr. Robert Wyrick, DDS. IE collected four (4) representative interior non-viable air
samples of the subject property to determine a possible negative impact by excessive airborne
fungal spores. A single (1) non-viable, outdoor reference air sample was collected to determine
the baseline levels of possible spore migration, levels and species from the outdoor environment.

                                                                 Project Name: GlassRatner/Council House
                                                                                Project No. IE-GR142-0212


A chain of custody (COC) was completed for the collected samples and the samples were
submitted to a certified, independent laboratory for analysis.

No destructive investigation of the subject property was authorized, recommended or
performed during this site assessment.

4.3 Analytical Results

       4.3.1 Standard Interpretation of Laboratory Results

Common biological dust components such as mold and pollen are not regulated and have no
established exposure criteria. Fungi are ubiquitous; they are a normal and important part of our
environment and will not proliferate and grow indoors unless their moisture requirement is met.
Fungi generally grow on cellulose-based material, such as wood or drywall paper. The detection
of fungi on a bulk sample of building material does not necessarily constitute the proliferation of
fungi on that material.

According to ACGIH, “Data from individual sampling episodes is often interpreted with respect
to baseline data from other environments or the same environment under anticipated low
exposure conditions.” In the absence of established acceptable exposure limits, it is often
necessary to use a comparison standard when interpreting data. In many instances, it will be
necessary to sample the suspect area as well as a non-suspect area.

According to ACGIH, “…active fungal growth in indoor environments is inappropriate and may
lead to exposure and adverse health effects.”

   a. Total Fungal Spores
              According to ACGIH, “…differences that can be detected with manageable
              sample sizes are likely to be in 10-fold multiplicative steps (e.g., 100 versus
              1000…)”. Following this logic, if total fungal spores are ten (10) times greater in the
              sample from suspect area than in the negative control sample collected from a
              non-suspect area, then that sample area may be a fungal amplification site.

   b. Mycelial Fragments
             Mycelium is a fungal mass that constitutes the vegetative or living body of a
             fungus. Following the same logic above, if total Mycelial fragments are ten (10)
             times greater in the suspect sample than in the negative control, then the sample
             area is considered to be a fungal amplification site. The presence of Mycelial
             fragments provides evidence of microbial growth.

   c. Toxic Molds
             Certain authorities refer to certain molds as important toxigenic taxa. The
             presence of a few spores or toxic mold should be interpreted with caution.
             Additionally, it should be recognized that these named molds are not necessarily
             the only ones of potential significance.

   d. Water Indicator Molds
             Certain authorities identify certain molds whose presence indicates excessive
             moisture. The presence of a few spores or water indicator mold should be
             interpreted with caution. Additionally, it should be recognized that these named
             molds are not necessarily the only ones of potential significance.

                                                                                Project No. IE-GR142-0212


   e. Mold Glossary
            Specific characteristics of individual, common fungi listed in the report are
            presented in Section 5.

The presence of few or trace amounts of fungal spores in bulk/surface sampling should be
considered background. Amounts greater than this or the presence of fungal fragments (e.g.,
hyphae and conidiophores) may suggest fungal colonization, growth and/or accumulation at or
near the sampled location according to the Guidelines on Assessment and Remediation of
Fungi in Indoor Environments by the New York City Department of Health & Mental Hygiene
Bureau of Environmental & Occupational Disease Epidemiology.

       4.3.2   Laboratory Results

A total of five (5) Non-viable Air Samples, Total Spore Trap Devices, were collected in
representative locations of the subject property along with an outside, reference sample to
establish background levels of the immediate environment. All non-viable air samples were
collected at a flow rate of 15 liters per minute for 5 minutes for a total volume of 75 liters.

All collected samples were individually sealed in locking storage bags and submitted to an
independent AIHA accredited and EMLAP certified laboratory (Aerobiology Laboratory
Associates, Inc., Atlanta, GA) for microscopic analysis, total spore identification and
quantification. Laboratory results are expressed in spores/m³ (spores/cubic meter) for air
samples. The results are as follows:

1. Penicillium/Aspergillus group spores are characterized by their small size, round to ovoid shape, being unicellular, and usually colorless to lightly
pigmented. There are numerous genera of fungi whose spore morphology is similar to that of the Penicillium/Aspergillus type. Two common
examples would be Paecilomyces and Acremonium. Although the majority of spores placed in this group are Penicillium, Aspergillus, or a
combination of both. Keep in mind that these are not the only two possibilities.
2. Ascospores are sexually produced fungal spores formed within an ascus. An ascus is a sac-like structure designed to discharge the ascospores
into the environment, e.g. Ascobolus.
3. Basidiospores are typically blown indoors from outdoors and rarely have an indoor source. However, in certain situations a high basidiospore
count indoors may be indicative of a wood decay problem or wet soil.
4. The Smut, Periconia, Myxomycete group is composed of three different groups whose spores have similar morphologies. Smuts are plant
pathogens, Periconia is a relatively uncommon mold indoors, and Myxomycetes are not fungi but slime molds. Although these organisms do not
typically proliferate indoors, their spores are potentially allergenic.
5. The colorless group contains colorless spores which were unidentifiable to a specific genus. Examples of this group include Acremonium,
Aphanocladium, Beauveria, Chrysosporium, Engyodontium microconidia, yeast, some arthrospores, as well as many others.
6. Rusts are plant pathogens that do not typically proliferate indoors unless an infected plant is present; their spores are potentially allergenic and
reflect entrainment from outdoor air.
7. Hyphae are the vegetative mode of fungi. Hyphal elements are fragments of individual Hyphae. They can break apart and become airborne
much like spores and are potentially allergenic. A mass of hyphal elements is termed the mycelium. Hyphae in high concentration are indicative of
colonization.
8. The positive-hole correction factor is a statistical tool which calculates a probable count from the raw count, taking into consideration that multiple
particles can impact on the same hole; for this reason the sum of the calculated counts may be less than the particle hole corrected total.
9. Due to rounding totals may not equal 100%.
10. Minimum Reporting Limits (MRL) for BULKS, DUSTS, SWABS, and WATER samples are a calculation based on the sample size and the
dilution plate on which the organism was counted. Results are a compilation of counts taken from multiple dilutions and multiple medias. This
means that every genus of fungi or bacteria recovered can be counted on the plate on which it is best represented.
11. If the final quantitative result is corrected for contamination based on the blank, the blank correction is stated in the sample comments section of
the report.
12. Analysis conducted on non-viable spore traps is completed using Indoor Environmental Standards Organization (IESO) Standard 2210.

13. The results in this report are related to this project and these samples only.

Terminology Used in Direct Exam Reporting
Conidiophores are a type of modified hyphae from which spores are born. When seen on a surface sample in moderate to numerous
concentrations they may be indicative of fungal growth.

4.3.3   Analysis of Sampling Results

Laboratory analysis of the non-viable air samples indicates that the types (species) of
aerosolized fungal spores presented in the indoor sampling results are consistent with the types
found in the outdoor reference comparison sample. Individual levels of the types identified were
found to be similar to the levels presented in the outdoor comparison sample and when
compared to the non-suspect indoor, ambient comparison locations. Total fungal spore levels in
all indoor sampling locations were found to be well below that of the outdoor comparison
sample. Put simply, an occupants’ exposure to a variety of airborne fungal spores would have
been greater in the outdoor environment than the indoor environment at the time of testing.

5.      Glossary of Common Fungi*

Absidia: Absidia sp. is a principal cause of zygomycosis, an infection of the skin. It can be found
in decaying plant material, making it a saprobe. It is recognized as an allergen however, only 1
species, A. corymbifera is considered a pathogen. Absidia is considered a zygomycete, sharing
close macro/microscopic homology with Mucor and Rhizopus sp.

Algae: Algae are microscopic plants that are found in fresh water, marine water and in damp
environments. The increased presence of algae would indicate a wet environment.

Alternaria: This genus compromises a large number of saprobes and plant pathogens. In
humans, it is recognized to cause type I and type III allergic responses. Because of the large size
of the spores, it can be deposited in the nose, mouth and upper respiratory tract. It has been
known to cause Baker’s asthma, farmer’s lung, and hay fever. Certain species of Alternaria have
the capability to produce tenuazonic acid and altertoxin, both mycotoxins. There are
approximately 40-50 different species of Alternaria. It is one of the more common fungi found in
nature. It is easily identified on tape lifts and non-viable analysis by its production of erect
conidiophores that are brown and multi-celled.

Arthrinium: This fungus is a saprobe and is found on plant material. There is no known mycotoxin
production and only one of approximately twenty species of Arthrinium is a potential allergen.

Ascospores: Ascospores are ubiquitous in nature and are commonly found in the outdoor
environment. They are identified on tape lifts and non-viable analysis by the fact that they have
no attachment scars and are sometimes enclosed in sheaths with or without sacs. Some fungi
that belong to the ascomycete family are the sexual forms of Penicillium/Aspergillus,
Chaetomium and Pleospora. This group contains possible allergens, mycotoxin producers and
opportunistic human pathogens.

Ascotricha: Ascotricha is in the family of ascomycetes, making it closely related to Chaetomium.
This genus has not been well studied, however, it has been associated with wood containing
materials.

Aureobasidium: Aureobasidium sp. is a yeast like organism that grows in areas with high moisture
content. This fungus is a saprobe and can also be pathogenic to plants. It has been isolated
from humans in skin lesions and from infections of the eye. Aureobasidium has the potential to
be a type I & III allergen.

Basidiospores: Basidiospores agents of wood rot and have the potential to produce a variety of
toxins. Members of this family produce type I and III fungal hypersensitivity reactions.

                                                                   Project Name: GlassRatner/Council House
                                                                                  Project No. IE-GR142-0212


Beauveria: Beauveria is a recognized parasite of plants and insects. It has been isolated from the
soil and is a saprobe. It is rarely isolated from human infections; usually from
immunocompromised individuals.

Botrytis: There have been no known cases of infection or mycotoxin production for this species.
Botrytis does has the potential to produce type I & III fungal hypersensitivity reactions. Botrytis is
commonly found in tropical and temperate climates growing on vegetative matter or as a plant
parasite.

Chaetomium: This genus is often found on materials containing cellulose, or other wet materials.
It is also considered part of the ascomycete group because its spores are released from a sac
called an ascus. Chaetomium can produce type I fungal hypersensitivity and has caused
onychomycosis (nail infections). Chaetomium species can also produce mycotoxins, one of
which being chaetomin.

Chrysosporium: Chrysosporium sp. is a saprobe and is common in the outdoor environment. This
genus is sometimes misidentified as a dermatophyte due to its morphological similarities and its
potential to infect the skin.

Cladosporium: Cladosporium spores are commonly found on dead plants, food, textiles and a
variety of other surfaces. This genus compromises perhaps the most common isolates in both the
indoor and outdoor environment. Some species produce a mycotoxin, epicladosporic acid that
acts in an immunosuppressive manner. Illnesses caused by this genus can include
phaeohyphomycosis, chromoblastomycosis, hay fever and common allergies.

Coelomycete: This term refers to a group of organisms that form conidia in ball like structures
called pycnidia. They are widely distributed and act as either saprobes or parasites to plants.
They are most often found on surfaces and not in the air because they are difficult to aerosolize.
Some species within this group can produce type I and III hypersensitivities. An example of a
coelomycete would be the fungus Phoma.

Colorless: These spores are round, smooth and colorless. There are no distinguishing features to
allow complete identification.

Clear brown: These spores are usually seen as round clear, brown spores. There are no
distinguishing features to allow complete identification.

Curvularia: Curvularia species is found on plant material and is considered a saprobe. It has
been reported to cause type I hypersensitivity and to be a cause of allergic fungal sinusitis.

Drechslera/Bipolaris group: This group of fungi constitutes the most commonly reported causes
of allergic fungal sinusitis. They produce type I fungal hypersensitivity in humans. In the wild, they
are plant parasites and are recovered from this type of material. Bipolaris sp. has been reported
to produce sterigmatocystin, a mycotoxin. Because of the microscopic similarities between the
two genuses, they are grouped together on both viable and non-viable analysis.

Epicoccum: Epicoccum is a saprophyte and considered a weakly parasitic secondary invader
of plants, moldy paper and textiles. Epicoccum is usually isolated with either Cladosporium
species or Aureobasidium species. It produces the mycotoxins flavipin and epicorazine A&B. It
also has the potential to produce type I fungal hypersensitivity reactions.

Fusarium: Fusarium is the most common cause of mycotic keratitis and has been isolated from
patients with a variety of infections. Fusarium is frequently isolated from plants and grains. It
requires wet conditions to grow, produces some potent trichothecene mycotoxins, and is a type
I allergen.

Geotrichum: Geotrichum species is commonly found in dairy products and the soil. It causes
geotrichosis, which can produce lesions in the mouth, intestines and other areas. Typically, these
infections only occur in the immunocompromised host. Geotrichum species also has the
potential to be an allergen.

Hyalodendron: This genus is closely related to Cladosporium, both microscopically and
genetically. Unlike Cladosporium, Hyalodendron does not produce a noticeable pigment.
Hyalodendron has been found to grow on wood and wood-containing products.

Hyphal elements: Hyphal elements are filamentous structures of a fungus.

Monilia: This genus which is now known as Chrysonilia is considered a laboratory contaminant.
This genus is not well studied, but has not been implicated in human disease and mycotoxin
production.

Nigrospora: Nigrospora sp. is usually considered a contaminant; its pathogenesis is not well
studied. It has been associated with type I allergic responses and is usually found in plant
material as a saprobe.

Paecilomyces: This genus is often found in soil and household dust. It is the causative agent of
paecilomycosis, which can manifest itself as keratitis, cellulitis, endocarditits, alveolitis and others.
It has the potential to produce patulin and paecilotoxins (mycotoxins) and is a type I and III
allergen.

Penicillium/Aspergillus: Penicillium spores are ubiquitous in environment. These spores are easily
aerosolized and can cause a variety of symptoms including allergic reactions, keratitis,
hypersensitivities and pneumonitis. Most are of these symptoms occur if the individual is
immunocompromised in some way (HIV, cancer, etc). Penicillium species also produce a wide
variety of mycotoxins including but not limited to ochratoxin, patulin, and citrinin.

Aspergillus species can produce a variety of symptoms and disease for an affected individual.
There are over 175 different Aspergillus species and they can produce type I and III fungal
hypersensitivities. There have been over 15 different species of Aspergillus implicated in either
producing mycotoxins or other deleterious health effects. Both Penicillium and Aspergillus spores
share similar morphology on non-viable analysis and therefore are lumped together into the
same group. Only through the visualization of reproductive structures can the genera be
distinguished.

Also included in this group are the spores of the genera Trichoderma, Acremonium, Verticillium
and Paecilomyces. Small, round spores of this group lack the necessary distinguishing
characteristics when seen on non-viable examination. Therefore, all of the above are included
in the category of Penicillium/Aspergillus group spores.

Phialophora: Phialophora is sometimes considered a plant pathogen, also found on wood,
grasses and other water loving substrates. P. verrucosa is one of the agents of
chromoblastomycosis in the tropical environments of the world. Its toxicity and allergenicity have
not been well studied.

Pithomyces: Pithomyces is commonly found on grass and decaying plant material. It has the
potential to produce the mycotoxin, sporidesmin.

Rhinocladiella: Rhinocladiella is a saprobe and can cause chromoblasomycosis, a rare infection
of the skin. This genus is usually isolated from decaying wood.

Rhizopus: Rhizopus, like Mucor and Absidia are all part of the zygomycete family. Rhizopus is an
agent of zygomycosis, which can cause necrosis of tissues and cause damage to the brain and
the intestines. These complications usually occur in immunocompromised individuals, or those at
risk for developing fungal infections. Rhizopus is commonly found in decaying fruits, plants and
grains. Some species are plant pathogens and can produce type I and III fungal hypersensitivity
reactions.

Rusts: Rusts are serious plant pathogens associated with cereal crops. These smut teliospores can
serve as potential allergens.

Scopulariopsis: Scopulariopsis rarely causes human infections and is typically found in water-
damaged materials. This genus can be an occupational allergen and has the ability to
decompose arsenic-containing compound to a toxic arsenic byproduct.

Smuts, Periconia, Myxomycetes: Smuts and Myxomycetes are parasitic plant pathogens and
can produce type I fungal hypersensitivity reactions. There are occasions where Periconia have
been implicated in mycotic keratitis, but this is a rare event. All three are typically grouped
together due to their association with plants, the outdoors and because they share similar
microscopic morphology.

Stachybotrys: Stachybotrys is commonly found in sub-tropical to tropical areas in soil and
decaying plant materials, and is considered a type I & III allergen. Considerable recent media
attention has been focused on the fungi Stachybotrys chartarum (atra). Stachybotrys thrives on
water damaged cellulose rich materials such as sheet rock, paper, ceiling tiles, cellulose
containing insulation backing and wallpaper. The presence of this fungus in buildings is
significant because of the mold’s ability to produce mycotoxins, such as Satratoxin H,
Trichoverrol, and Cyclosporins that possess cytotoxic, immunological, carcinogenic effects.
Exposure to these toxins can occur through inhalation, ingestion or dermal exposure. Symptoms
include dermatitis, cough, rhinitis, nose bleeds, a burning sensation in the mouth and nasal
passage, cold and flu symptoms, headache, general malaise, and fever. Inhalation of conidia
may also induce pathological changes (pneumomycotoxicoses). Satratoxin H has been
reported to be abortogenic in animals and in high doses or chronic low doses it can be lethal. S.
chartarum (atra) produces other macrocyclic and trichoverroid trichothecenes and, like
Memnoniella echinata, produces phenylspirodrimanes, which are immunosuppressive.
Stachybotrys typically appears as a sooty black fungus occasionally accompanied by a thick
mass of white mycelia. Memnoniella differs from Stachybotrys by producing conidia in chains. As
a general rule, air sampling for Stachybotrys yields unpredictable results mainly due to the fact
that this fungus is usually accompanied by other fungi such as Aspergillus and Penicillium that
normally are better aerosolized than Stachybotrys. Bulk or surface sampling of suspect materials
can be analyzed in a laboratory for identification by light microscopy. This fungus is a slow
grower on media, therefore does not compete well with other rapidly growing fungi. Colonies
are powdery in texture, white, pink, orange or black in color. The species S. chartarum (atra)
produces colonies black in color.

Sterilia mycelia: Sterilia mycelia refers to a group of fungi that do not sporulate. In the laboratory,
fungal identification is done by visualizing spore production. Sometimes fungi do not grow well
on the media supplied, or require other growth conditions to fully sporulate. In this case, our
laboratory refers to this group of fungi as Sterilia mycelia.

Sporobolomyces: This fungus is often associated with other plant parasites and can be found in
plant lesions as well as in trees and other wood substrates. It produces type I and III allergic
reactions and is often found in high concentrations in humid environments.

Sporothrix: Sporothrix schenckii is a dimorphic fungus that is the causative agent of sporotrichosis.
This disease, also called Rose Gardeners disease, occurs when the organism is deposited
subcutaneously usually by the pricking of ones finger on garden plants. The condition that
follows is an inflammatory reaction usually in the upper layers of the skin. On occasion, the
disease can progress to the bones, joints and other organs.

Sporotrichum: Sporotrichum is usually considered non pathogenic, but sometimes it can
produce allergic reactions. This genus is usually isolated from decaying plants and plant
materials. Microscopically, this fungus can resemble Sporothrix, however, it can be identified as
a colorless spore.

Stemphylium: Stemphylium has been reported to be a type I allergen and is considered a
contaminant. It is usually isolated from dead materials and is either parasitic or saprophytic.

Syncephalastrum: This genus is usually found in tropical and subtropical areas. Syncephalastrum
is found in soil, considered a saprobe and is considered non-pathogenic. However, when found
on arsenic containing compounds, Syncephalastrum has the potential to liberate free arsenic
from materials.

Torula herbarum: Torula is a saprophyte and is reported to produce type I fungal hypersensitivity.
It is typically found in wood-containing materials.

Trichocladium: This organism has been identified in soils and on dead wood. The genus is not
well studied.

Trichoderma: Trichoderma is commonly isolated in soils, air and in plant materials. It is usually
considered non pathogenic, however, it has the possibility to produce trichocethene
mycotoxins and symptoms similar to that of "Sick Building Syndrome." Trichoderma is also
considered a type I and III allergen. In the laboratory, Trichoderma can be a contaminant due
to the fact that it can produce confluent growth and take over an entire culture.

Ulocladium: Ulocladium species is reported to be a major allergen. It can be found on many
types of materials, but mostly found on decaying materials. Rarely it can cause subcutaneous
infections in humans. It has a high water requirement and its ability to produce mycotoxins is not
fully understood.

Unknown: This group consists primarily of dark, brown spores. There are no distinguishing features
to allow complete identification.

Ustilago: Ustilago is considered a major plant pathogen. It is a smut and can produce type I
allergic reactions. In culture, it resembles a yeast like organism.

Verticillium: Verticillium is considered non pathogenic, but this genus is not well studied. It is
known to cause decay of plant material and certain species are parasites on plants and other
fungi.

Wallemia: Wallemia is known to produce type I hypersensitivity reactions and can produce a
variety of mycotoxins. This genus is typically found in dry areas.

Yeasts: Yeasts are found worldwide in a variety of natural habitats or organic substrates such as
plant leaves, flowers, soil, and salt water and are often able to grow at reduced oxygen levels.
They can also be found on the skin surfaces and in the intestinal tracts of warm-blooded
animals, where they might be considered parasites, but can live symbiotically. Some yeast is
reported to be allergenic, and may cause problems in individuals with previous exposure and
developed hypersensitivities.

Candida: Candida species are part of the microflora of humans. Candida albicans has the
potential to cause a variety of diseases in humans, either in immunocompromised individuals or
in those receiving antibiotic therapy. It can cause thrush, an infection in the mouth area, usually
occurring in small children. Candida is also the most common cause of fungal urinary tract
infections and pneumonia.

Cryptoccocus: This yeast has the potential to cause a myriad of infections of the lung, blood,
skin, mucous membranes and meninges. Cryptococcus is normally associated with infections of
the cerebral spinal fluid and meninges, usually in immunocompromised hosts. The basidiospores
of cryptococcus are readily airborne, which would explain why aerobolized pigeon droppings
are often considered when looking for a source of cryptococcal infection.

     6. CONCLUSION

Based on the laboratory analysis of the non-viable air sampling to date, the results for
aerosolized fungal spores were generally consistent with the outdoor comparison sample and
non-suspect, indoor sample distributions. Total indoor spore levels were found to be well below
that of the outdoor air sample and are not considered amplified according to the American
Conference of Governmental Industrial Hygienists (ACGIH) guidelines. Put simply, an occupants’
exposure to a variety of fungal spores would have been greater in the outdoor environment
than the indoor environment at the time of testing. The assessed location is not considered an
amplified site for mold.

The visual re-assessment of the previous work areas of the subject property indicated neither
active water infiltration nor reemergence of fungal staining or growth to the remediated building
substrates.

No additional fungal remediation activities are currently recommended to the previously
affected work areas of the subject property.

7.      RECOMMENDATIONS

Based on the results of this review, the following recommendations were developed for the
subject property:

7.1 As a general recommendation, IE recommends continuing to maintain indoor relative
humidity levels in accordance with guidelines established by the American Society of Heating
Ventilation and Air Conditioning Engineers (ASHRAE). Those guidelines suggest maintaining


                                                  - 14 -
                                                                   Project Name: GlassRatner/Council House
                                                                                  Project No. IE-GR142-0212


indoor relative humidity levels between 30-60%RH. Maintaining indoor relative humidity at these
levels will generally not promote fungal and bacterial growth.

7.2 As a general recommendation, any future water losses to the property should be attended
to within a 24-48 hour time period of discovery in order to minimize the likelihood of fungal
growth. [EPA guidelines (EPA Publication No. 402-K-01-001)] states “for the response to clean
water damage within 24-48 hours to prevent mold growth.”].
