Sample Information Log of Custody) and -l' Section I Introduction On July 18, 2010, HEI Systems was retained to conduct an assessment related to a reported malodorous condition within the South Miami City Hall building located at 6130 Sunset Drive, South Miami, Florida 33143. The stated purpose of the assessment was to identify and determine both the presence and extent of the odor within the interior of the building, and to identify potential sources of the odor(s) and to make corrective recommendations for their removal. On Thursday, August 1, 2013, HEI Systems performed a walk- through inspection for any visual or osmic evidence that would lead to any malodorous condition. Present during the August 1, 2013 assessment was Richard H. McMonagle, Ph. D., CIE, and Stacy S. Davids, Ph. D., from HEI Systems, along with Ms. Maria L.

The report is prepared in accordance with recognized procedures and appropriate scientific methods applicable and used by professionals in this field. This report is based ilnon the infol•matinn available to 14PT gv4tP.mQ at this time, as described in Section TV, Basis of Report.

I►AN Section 11 Discussion Prior to tabulating conditions with the City Hall building that are conducive to the creation of a malodorous condition, a brief understanding of factors relating to the common body of knowledge regarding odors in building is presented. There are widely differing "opinions" about odors among people, but for the purpose of this assessment, the following definitions will apply. First, odors are gases that people notice. Odors emanate from a source, into the air, where they are perceived. Odors are perceived when odorous molecules contact olfactory nerve endings in the nasal cavities. These sensations are then transmitted to the olfactory lobe. This is referred to as "real odor ". The basis of this assessment deals with real odor. "Heightened Awareness Odor" or "Psychological Odors" are terms used to describe odors that people "believe" they smell, based upon experiences, suggestions and past impressions, e.g. when people believe that the odor in their surrounding area is not "normal ". This assessment does not deal with heightened awareness odor. In order to be smelled, material must have certain properties: 1. It must be volatile, and be able to evaporate molecules into the air. 2. An odor bearing molecule must be soluble in water, even if only to an infinitesimal degree. If it is not water soluble, it will be barred from reaching nerve endings by the watery film that covers their surface. 3. Odor bearing substances must be soluble in lipids or fatty substances, which enables them to penetrate the nerve endings through the lipid layer that forms part of the surface membrane of every cell. 4. Finally, odor bearing molecules must be customarily absent from the nasal tissue. The ability of a material to hold odors is related to its porosity. The more porous a substance is, the more likely it is to adsorb odors. This process is known as preferential adsorption. A natural wick is a highly porous substance that tends to tenaciously cling to malodors. Some natural wicks include fabric, cellulose ceiling tiles, paper, cardboard, carpet, and unsealed concrete. Additionally, odor is most apparent when both temperature and relative humidity are high. In conducting our assessment for malodorous conditions within the South Miami City Hall building, we focused upon potential sources, confirmation through sampling and recommendations for removal of the malodors from the building. When recorded with a digital psychrometer, temperatures and relative humidity were within acceptable ranges (ASHRAE Standards) throughout the building. However, it should be noted that the relative humidity was > 10% the average in the Commission Chambers Room and the Mail Room at the entrance to the Finance Department. A summary of temperature and relative humidity is presented in the table below. -3- Manager's Conference Room 73..0° F 47.5% Executive Assistant's Office 73.4° F 453% City Managers O Ice _ 73.46 F 44.8% City Manager's Back Office 73.0° �.._�._..__._._.__.��... 43.9% Hallway - . o Lobby 72.8° F 44.8% Finance Office root 71.2° F_. 44.8 °0 - Finance Office -.

These are articulated below. The carpeting throughout the building is old, damaged, stained, odorous, and at the end or its normal lifespan or beyond. The carpet is replete with excessive and undifferentiated debris, insect and lizard parts, skin cells, fiberglass, and fungal spores that are no longer removable by normal maintenance and cleaning. The carpeting is beyond normal cleaning and should be removed and discarded throughout the building. The concrete slab beneath the carpeting should be abrasively cleaned and sealed, prior to -4- the installation of any new floor covering. Carpeting, as a new floor covering would not be recommended, rather, some form of hard surface floor covering. Should the carpeting be found to be installed upon vinyl composition tile or linoleum, then the vinyl sub- surface should be removed and discarded to the slab, and then the slab abrasively cleaned and sealed prior to the installation of any new floor covering. Vinyl composition and linoleum surfaces are usually the most difficult to decontaminate as they have a tendency to adsorb and hold odors for a long period of time. Paper and cardboard boxes stored on the floor contribute to malodorous conditions. This condition was observed in the Manager's Conference Room, HVAC Room, the Human Resource Department and the Records Room. Banker Boxes and Cardboard storage should be placed upon shelving and plastic containers should be considered. Stained ceiling tiles should be removed and discarded as they are repositories for fungal growth and malodorous conditions. The source of the staining should be defined and repaired. Stained ceiling tiles were noted in the Commission Chambers Room. The vertical carpet soundproofing at the front of the Commission Chambers Room is malodorous, water damaged and separating at some seams. The exposed glue on the back side of the carpet presents with suspect fungal growth. This carpeting should be removed and discarded, and the remaining glues abrasively removed from the wall and the wall sealed. Intrusions of warm, humid air through the building envelop should be sealed to prevent any further intrusion and subsequent condensation, water intrusion and damage, corrosion, staining and fungal growth. Intrusions of warm, humid air were found in the Commission Chambers beneath the exterior windows and the exterior metal door leading out to the generator. The area beneath the windows is allowing moisture and insects to enter the room. The door is corroded and daylight can be observed on both sides of the door when the door is fully closed at the bottom. Weather stripping and sealing are recommended for this door. Unsealed concrete and cracking were observed in the HVAC Room in the walls and ceiling. All of the cracks should be sealed to prevent intrusion of water and outside air. Staining on the concrete at the wall bottoms and from the ceiling down is indicative of a history of water intrusion into the room. The interior component fiberglass insulation within the HVAC system air - handlers upstream of the filters was absorbed with dirt, debris, fungal growth (diffused into the fiberglass insulation) and allowing these particulate to be distributed throughout the building via the supply diffusers. Evidence of these particulate is seen on the covers and louvers of the supply diffusers throughout the building. The wall bottom of the Commission Chambers, the wall in the Mail Room outside of the Finance Department and the supply diffuser in the Women's Restroom adjacent to the Lobby are elevated in settled Cladosporium spore counts. Elevated C,ladosporium counts associated with this -5- particular genus of fungal growth within HVAC systems are considered common. It is recommended that "time-release" activated charcoal be placed in the return plenums of the air-handlers to reduce odor throughout the building.

Sampling: A five liter aerosol samples was collected from the carpet in the City Manager's Office to ascertain the debris and particulate load in this carpet. Total enumeration was not possible due to the excessive load of debris present within the carpet. Observed in the sample were Basidiospores, Undifferentiated Pollen spores, Fiberglass fibers, Cellulose Fibers, Insect parts and Skin Cells. Basidiospores are the sexual spores produced by Basidiomycetes. Basidiomycetes are a class of fungi characterized by spores formed on basidia. They include mushrooms, toadstools, boletes, wood bracket fungi, and puffballs. Some species are edible, such as Agaricus bisporus, the commercially cultivated mushroom. A few species cause wood brown rot, white rot, and dry rot in buildings. A five liter aerosol sample was collected from the cat -net in the Commission Chamber's to ascertain the debris and particulate load in these carpets. Total enumeration was not possible due to the excessive load of debris present within the carpet. Observed in the sample were Aspergillus /Penicillium -like spores, Cladosporium spores, Epicoccum spores, Smut /Myxomyces /Periconia spores, Hyphal Fragments, Undifferentiated Pollen spores, Cellulose Fibers, Insect parts and Skin Cells. Aspergillus and Penicillium spores are often difficult to distinguish microscopically, and are commonly grouped together in the analysis of total count samples. All spore -trap (Allergenco -D ) samples are total count samples. Aspergillus is found in soil, compost piles, decaying vegetation, stored grain, and other kinds of organic matter. Aspergillus can also be found indoors in water - damaged buildings. Some species are able to produce mycotoxins, depending upon the species, substrate, and /or food source. Penicillium consists of many species that are common contaminants on a variety of substrates. Penicillium may be found indoors in air samples, carpet dust, or on wallpaper. Some species are able to produce mycotoxins depending upon the species, substrate, and /or food source. Cladosporium are widely distributed as plant pathogens and saprobes. Cladosporium is the most frequently found fungus in outdoor air. Indoors, Cladosporium usually occurs at low concentrations in damp or humid areas, but may be found in high concentrations in water - damaged building materials. Its ability to sporulate heavily and to get airborne makes it an important fungal allergen. Cladosporium is only occasionally associated with disease in humans. The most common species include Cladosporium elatum, Cladosporium herbarum, Cladosporium sphaerospermum, and Cladosporium cladosporioides. Some Cladosporium spp. are causative agents of skin lesions, keratitis, onychomycosis, sinusitis and pulmonary infections. Species of Cladosporium are not human pathogens except in some cases of immuno - compromised patients. However, Cladosporium species have the ability to trigger allergic reactions to sensitive individuals. Prolonged exposure to elevated spore concentrations can elicit chronic allergy and asthma. Concentrations of 3000 Cladosporium spores per cubic meter of air are generally taken as the threshold concentrations for clinical significance. However, individuals may react at lower concentrations depending on their sensitivity. Spores of Cladosporium are formed in simple or branched loose chains. They vary greatly in size (5 -40 x 3 -13 µm) and shape (ovoid, lemon - shaped, oblong, spherical). They are easily detected in spore traps, although small single celled spores may be easily mistaken for spores of other molds. Only the small sized spores (about 0.6% of total airborne spores of Cladosporium) can penetrate into the terminal bronchi and alveoli in humans. Epicoceum fungi are commonly Epicoceum are found in paper and textiles. Type I allergenic potential. found in plant debris and soil. Indoors, They are disseminated by wind and have a Hyphal Fragments are portions of the fungal mycelium that do not have any spores or other diagnostic fungal structures, and therefore could not be identified. Myxomycetes are popularly called slime molds. They are not true fungi, taxonomically. Some species are found in the soil, in decaying wood, or other organic matter, where they produce structures full of powdery resting spores. Periconia is found outdoors in grasses, dead herbaceous plant material, rushes and soils. It is primarily disseminated by the wind and is known to produce Periconia cireinata that subsequently produces Perieonin A and Periconin B; both of which are biologically inactive. Smuts are pathogens of cereals crops, corn, grasses, onion, and sorghum. Smut fungi require a living plant host for growth. They are disseminated throughout the environment by wind, rain, shoes and lawnmowers. Smut fungi belong to the order Ustilaginales and there are about 4000 known species. Smuts are associated with Type I allergens (Hay Fever and Asthma). -9- A direct sample was collected by sterile swab from the Commission Chambers wall bottom beneath the exterior windows, as a response to the moisture intrusion, and suspect fungal growth on the surface. This sample was approximately 1 cm2 in dimension. The results of this sample analysis by AEML, Inc. revealed the presence of 7,120 Asper•gillus /1'erticilliu111-like spores /crn2 10,800 Cladosporium spores /cm2 and 880 1 lyphal Fragments /cm" in the sample collected. A direct sample was collected by sterile swab from the Commission Chambers window frame, as a response to the moisture intrusion, and suspect fungal growth on the surface. This sample was approximately 1 cm in dimension. The results of this sample analysis by AEML, Inc. revealed the presence of 80 Cladosporium spores /cm2 and 80 Curvularia spores /cm2 in the sample collected. Curvularia is a common saprobe found in soil, plants, cereals, and cellulose materials such as paper and archives. Some species are plant pathogens, but can also occur indoors. Curvularia is allergenic and may cause infections in immunocompromised people. A direct sample was collected by sterile swab from the Finance Department Mail Room wall, as a response to the suspect fungal growth on the wall surface. This sample was approximately I cm2 in dimension. The results of this sample analysis by AEML, Inc. revealed the presence of 942,000 Cladosporium spores /cmz and 43,800 Hyphal Fragments /cm2 in the sample collected. It should be noted that when a large number of hyphal fragments is associated with the spores collected in a sample, it is typically indicative of the viability of the spores in the sample. A direct sample was collected by sterile swab from the Lobby Women's Room supply diffuser,, as a response to the suspect fungal growth on the surface. This sample was approximately I cmz in dimension. The results of this sample analysis by AEML., Inc. revealed the presence of 89,000 Cladosporium spores /crnz; 480 Ganoderma spores /cmz and 3,280 Hyphal Fragments /cm2 in the sample collected. Ganoderma are large, very hard, woody bracket fungi that grow on living and dead trees.
