The District has decided to take a proactive approach and conduct an indoor air quality to determine the health status of the building. An IAQ involves the use of detector tubes/grab samples to determine if further investigation is warranted. The detector tubes are accurate enough to determine the hazards in the workplace. Detector tube pump systems are a very effective way to conduct on-the-spot air monitoring and meet the OSHA requirement of 25% error. It was determined, that the average concentration of nuisance dust, formaldehyde, ozone, nitrogen dioxide carbon monoxide, carbon dioxide and total petroleum hydrocarbons were below or equal to the outside sample. DRAFT The organisms identified in the indoor air samples had MoldSCORE that ranged from The indoor air samples had a MoldSCORE below 150, which indicates that there is a low probability that the spores originated inside the building and no action is required. Bioaerosol sampling only represents a snap shot in time and the true average concentration of microorganisms may differ. Molds are part of the natural environment, and can be found everywhere, indoors and outdoors. They are found in schools, homes, hospitals, industry etc. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees. It is impossible to get rid of all mold and mold spores indoors; some mold spores will be found floating through the air and in house/school dust. However, mold is not usually a problem, unless it begins growing indoors and not appropriately corrected. Mold exposure can irritate the eyes, skin, nose, throat, and lungs of both mold-allergic and non-allergic people. Symptoms other than the allergic and irritant types are not commonly reported as a result of inhaling mold. The average concentration for nuisance dust, formaldehyde, ozone, nitrogen dioxide carbon monoxide, carbon dioxide and total petroleum hydrocarbons, in all the spaces investigated, were below or equal to the outside sample.

5 1.0 INTRODUCTION The Scarsdale UFSD retained Regulatory Compliance to conduct an indoor air quality (IAQ) screening at the High School. The District has decided to take a proactive approach and conduct an indoor air quality to determine the health status of the building. An IAQ involves the use of detector tubes/grab samples to determine if further investigation is warranted. The detector tubes are accurate enough to determine the hazards in the workplace. Detector tube pump systems are very effective way to conduct on-the-spot air monitoring and meet the OSHA requirement of 25% error. DRAFT Environmental Conditions (11/17/18): 39 0 F and 70% RH. Precipitation event: None A baseline IAQ was conducted to determine if the concerns were related to the environment of the building. The investigation consisted of the following: Carbon monoxide (CO) Carbon dioxide (CO 2 ) Nitrogen dioxide (NO 2 ) Ozone (O 3 ) Formaldehyde (CHO) Total Petroleum Hydrocarbons (TPH) Biological sampling Temperature (T) Total nuisance dust Relative humidity (RH) 1.1 REASON FOR CHOOSING THE SAMPLING PARAMETERS Carbon monoxide (CO): is an odorless, colorless gas that interferes with the delivery of oxygen in the blood to the rest of the body. It is produced by the incomplete combustion of fuels. The major sources of CO are cigarettes, motor vehicles, and defective combustion equipment such as furnaces, boilers and hot water heaters. Problems can arise from improper installation, maintenance and inadequate ventilation. 5

6 1.1.2 Carbon dioxide (CO 2 ): in the ranges encountered in the indoor environment does not constitute a health hazard. Carbon dioxide is a normal constituent of exhaled breath and, if monitored, can be used as a screening technique to evaluate whether adequate quantities of outside air (OA) is being introduced into the building. As carbon dioxide levels rise, it indicates that the ventilating system is malfunctioning or the design occupancy of the room is being exceeded. When this happens, a buildup up of common indoor air pollutants can occur, leading to discomfort or health complaints. Inadequate ventilation is a major cause of health complaints such as, respiratory, eye, nose, and throat irritation, lethargy and headaches Nitrogen Dioxide (NO 2 ) is a combustion product from furnaces, motor vehicles, welding and combustion equipment. NO 2 is a colorless gas that can cause headaches, nausea, dizziness, vomiting, coughing and irritation of the respiratory tract, shortness of breath, and increased incidences of respiratory illness. Children and individuals with asthma and other respiratory illness are at greater risk from exposure to nitrogen oxides. DRAFT Ozone (O 3 ) is a pollutant from automobile pollution and sunlight, lighting, electronic equipment, electrostatic air cleaners and copy machines. Ozone can be irritating to the eyes, mucous membranes and cause upper respiratory tract irritation Formaldehyde (HCHO) is a colorless, organic compound of carbon, hydrogen and oxygen having the formula HCHO. It is used extensively in industry in the production of synthetic urea and urea-formaldehyde resins, which themselves are widely used as adhesives in making particle board, laminates, plywood and other wood products. Many adhesives and glues also contain this compound, including some used for carpets and wallpaper coverings. Another widely used product-containing formaldehyde is ureaformaldehyde foam insulation. Formaldehyde is also used as a flame retardant for fabrics. Other sources include bulked stored paper products, some cosmetic products, combustion processes including smoking, and atmospheric photochemical smog. The potential for formaldehyde products to be present in the building air is considerable. The main concern is the potential for out-gassing. Airborne formaldehyde can cause irritation to the eyes nose, throat, and the respiratory tract. Prolonged exposure can cause sanitization and/or allergic reactions Total Petroleum Hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil. Crude oil is used to make petroleum products, which can contaminate the environment. Because there are so many different chemicals in crude oil and in other petroleum products (Tar from roofing compounds), it is not practical to measure each one separately. However, it is useful to measure the total amount of TPH at a site. Most people can withstand short exposures to fuel oil vapors without any problems. However, breathing fuel oil vapors overtime can affect a person's ability to smell and taste. High levels can cause headaches, nausea, light-headedness, poor coordination, increased blood pressure and difficulty concentrating. Most people can smell oil vapors at levels as low as 0.1 parts per million (ppm) in air. 6

7 1.1.7 Total Nuisance Dust is the amount of dust found in the air and the health hazards include itching and irritation to the skin and upper respiratory system, respiratory infection, and aggravation of existing respiratory or cardiovascular disease in elevated levels Temperature (T) and Relative Humidity (RH) are considered thermal comfort variables and should not be overlooked. The majority of indoor air quality (IAQ) complaints are related to these 2 parameters. Furthermore, temperature and humidity are variables that affect other indoor air contaminates. American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) has published guidelines describing thermal environmental conditions (ASHRAE Standard , Thermal Environmental Conditions for Human Occupancy). These guidelines are intended to achieve thermal conditions in a given environment that at least 80% of the persons who occupy that environment will find acceptable or comfortable. Temperature and humidity are comfort parameters that have been cited as the source of over 35% of indoor air quality complaints. Dry air can affect the human body by causing respiratory ailments such as asthma, bronchitis, sinusitis, and nosebleeds, or general dehydration since the body fluids are depleted during respiration. Skin moisture evaporation can cause skin irritations and eye itching and the apparent temperature of the air is lower than what the thermometer indicates and the body feels colder. DRAFT Bioaerosols are airborne particles, large molecules, or volatile compounds that are living or were released from a living organism. The concern regarding the indoor environments is centered on fungi. Fungi are ubiquitous organisms that can be found in indoor environments wherever food and moisture conditions are conducive to their growth. The microorganisms found in outdoor air grow on moist surfaces of leaves and soils; these organisms infiltrate into the indoor environment or may be transported into the building by people. Thus, fungi and bacteria are commonly found in indoor air and on the surfaces of floor, wall, and ceiling systems or on surfaces in air-handling equipment. When mold spores are present in large numbers, they can cause allergic reactions, asthma episodes, infections and other respiratory problems. Although proof of the connection between specific exposures and symptoms is often impossible to obtain, it is possible to demonstrate bioaerosol reservoirs, amplifiers, and disseminators during the inspection Individual susceptibility, the aforementioned factors do not affect all people equally: susceptibility varies with a range of factors such as atopy (predisposition to allergic sensitization), prior exposure, stress and gender. In some cases, the basis of the relationship is not clear. 1.2 SAMPLING METHODOLOGY Temperature and humidity were measured using the EXTECH Thermo-Hygrometer. Carbon dioxide was measured using a Telaire Carbon monoxide was measured using an MSA MiniCO Detector. Nitrogen dioxide, formaldehyde and ozone were 7

8 measured using an MSA Kwik-Draw Pump detector tube. Total Petroleum Hydrocarbons was measured using an Accuro Pump detector tube. Total nuisance dust was collected with a MIE personal DataRam (a real-time aerosol monitor). Biological, non-viable, total spore count samples were collected on Air-O-Cell cassettes at a flow rate of 10 liters per minute for approximately 10 minutes. The samples were sent to Environmental Laboratory Services (EM Lab) for identification. 2.0 RESULTS Table 2.1: The temperature and humidity and the CO, CO 2, formaldehyde, nitrogen oxides, ozone, total petroleum hydrocarbons and total dust sample results are listed below: ID # Location DRAFT CO (ppm) CO 2 (ppm) TPH (mg/m 3 ) CHO (mg/m 3 ) NO 2 (ppm) O 3 (ppm) T/H 0 f/% Total Dust (mg/m 3 ) 1 Outside BDL BDL BDL BDL 39/ Sample #1 2 Outside BDL BDL BDL BDL 44/ Sample #2 3 Room BDL BDL BDL BDL 80/ Room BDL BDL BDL BDL 77/ Room BDL BDL BDL BDL 79/ Room BDL BDL BDL BDL 80/ Room 2N BDL BDL BDL BDL 69/ Room 2N BDL BDL BDL BDL 70/ Room 2N BDL BDL BDL BDL 76/ Room 2N BDL BDL BDL BDL 70/ Room BDL BDL BDL BDL 71/ Room BDL BDL BDL BDL 71/ Room BDL BDL BDL BDL 74/ Room BDL BDL BDL BDL 72/ Room BDL BDL BDL BDL 73/ Room BDL BDL BDL BDL 73/ Room BDL BDL BDL BDL 75/ Room BDL BDL BDL BDL 72/ Room BDL BDL BDL BDL 73/ Room BDL BDL BDL BDL 75/ Room BDL BDL BDL BDL 75/ Room BDL BDL BDL BDL 75/ Room BDL BDL BDL BDL 75/ Room BDL BDL BDL BDL 74/ Room BDL BDL BDL BDL 75/ Design Lab BDL BDL BDL BDL 76/ Room BDL BDL BDL BDL 79/

The CO 2 levels were below the ASHRAE guidelines of 0 ppm. 3.2 Carbon monoxide: The average indoor CO concentration is equal to the outdoor concentration. 3.3 Nitrogen dioxide: The average indoor NO 2 concentration is below or equal to the comparison sample and the outdoor concentration. No standards have been agreed upon for nitrogen dioxides in indoor air. ASHRAE and the EPA National Ambient Air Quality Standards list ppm as the average 24-hour limit for NO 2 in outdoor air. 3.4 Ozone: The average indoor O 3 concentration is below or equal to the comparison sample and the outdoor concentration. Maximum allowable ozone concentration recommended by ASHRAE in an air conditioned and ventilated space to ppm. 13

14 3.5 Formaldehyde: The average indoor formaldehyde concentration is below or equal to the comparison sample and the outdoor concentration. 3.6 Total Petroleum Hydrocarbons: The average indoor total petroleum hydrocarbons concentration is equal to the non-compliant area and the outdoor concentration. There is no OSHA standard for the amount of petroleum oil vapors allowed in homes or workplaces. Most people can smell oil vapors at levels as low as 0.1 parts per million (ppm) in air. DRAFT 3.7 Total nuisance dust: The average indoor total dust concentration is below or equal to the comparison sample and the outdoor concentration. 3.8 Temperature and Humidity: Humidity, like temperature, exerts a powerful effect on building inhabitants. The direct consequence of high humidity is discomfort. Highly saturated warm air reduces the body s ability to lose heat and can increase levels of body odors. The chief problem with high indoor humidity, from a health standpoint, is the potential for mold growth. Humidity levels greater than 30% increase the potential for mold growth and high humidity, 60% or greater can cause biological contamination. Dry air can affect the human body by causing respiratory ailments such as asthma, bronchitis, sinusitis, and nosebleeds, or general dehydration since the body fluids are depleted during respiration. Skin moisture evaporation can cause skin irritations and eye itching and the apparent temperature of the air is lower than what the thermometer indicates and the body feels colder. The humidity level in the building is typical of buildings without mechanical ventilation during the autumn months. Recommended Ranges of Temperature and Relative Humidity Relative Winter Summer Humidity Temperature Temperature 30% 68.5 o F 75.5 o F 74.0 o F 80.0 o F 40% 68.0 o F 75.0 o F 73.5 o F 80.0 o F 50% 68.0 o F 74.5 o F 73.0 o F 79.0 o F 60% 67.5 o F 74.0 o F 73.0 o F 78.5 o F 3.9 Bioaerosols: Samples were collected from selected areas in the building and an outside sample was collected to determine the organisms that occupy the ambient air (mycoflora) at the time of the investigation. Because there can be such variation in spore trap samples, the statistical significance from collecting few samples is very limited and no single particulate sample is representative of any environment (the particles are never randomly distributed in the 14

15 space, especially when the particles are bioaerosols) therefore, two (2) outdoor air samples were collected. Two outdoor air samples will help provide a more complete picture of what is in the air that may be entering the building through windows and doors at times when they are open. The organisms identified in the indoor air samples had MoldSCORE that ranged from The indoor air samples had a MoldSCORE below 150, which indicates that there is a low probability that the spores originated inside the building and no action is required. Bioaerosol sampling only represents a snap shot in time and the true average concentration of microorganisms may differ. DRAFT Molds are part of the natural environment, and can be found everywhere, indoors and outdoors. They are found in schools, homes, hospitals, industry etc. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees. It is impossible to get rid of all mold and mold spores indoors; some mold spores will be found floating through the air and in house/school dust. However, mold is not usually a problem, unless it begins growing indoors and not appropriately corrected. Mold exposure can irritate the eyes, skin, nose, throat, and lungs of both mold-allergic and non-allergic people. Symptoms other than the allergic and irritant types are not commonly reported as a result of inhaling mold. The presence of fungi in the air does not necessitate that people will be ill or exhibit health effects. In order for humans to be exposed indoors, fungal spores, fragments, or metabolites must be released into the air and inhaled, physically contacted (dermal exposure), or ingested. Whether or not symptoms develop in people exposed to fungi depends on the nature of the fungal material (e.g., allergenic, toxic, or infectious), the amount of exposure, and the susceptibility of exposed persons. Susceptibility varies with the genetic predisposition (e.g., allergic reactions do not always occur in all individuals), age, state of health, and concurrent exposures. For this reason, and because measurements are not standardized and biological markers of exposures to fungi are largely unknown, it is not possible to determine a safe or unsafe levels of exposure for people in general. Since there is no biological concentration standards or permissible exposure limits (PELs) against which to compare a particular bioaerosol result, we are forced to use several tools to assist in the interpretation of the bioaerosol results. The current approach relies on the comparisons of indoor vs. outdoor results and complaint vs. non-complaint area results. 1. Indoor levels that are below outdoor levels are usually not a concern, unless an opportunistic pathogen is identified. 2. Compare the total concentrations from indoor, outdoor, complaint and noncomplaint areas. Indoor levels may be greater than the exterior sample concentration (a concentration effect might be occurring or the outdoor environmental conditions may be prohibiting reproduction or removing the spores from the air). 15

16 3. Compare fungal genera and species, similar genera and species should be present in the exterior and interior samples, complaint and non-complaint samples. Another tool that was developed by EM Laboratory Inc, is a proprietary statistical calculation called a MoldSCORE TM. The MoldSCORE TM is a method for examining airsampling spore data only. The statistical valves lay between and 300, the lower the score the greater the likihood that the indoor spores originated from the outdoors. The organisms identified in the indoor air samples are typically those found in the air from the exterior of the building. The MoldSCORE TM. suggest that the mold identified in the areas surveyed is from an exterior source. DRAFT It must be noted that these numerical values are only an assumption based on experience and scientific literature. The numbers are artificial and should not be used as a health and safety standard. It should also be noted, that rather than focusing on specific kinds of fungi or on quantitative measurements of fungal prevalence, the ACGIH approach has been to emphasize that actual fungal growth in indoor environments is inappropriate and may lead to exposure and adverse health affect Carpets, throw rugs and upholstery (throw cushions): Carpets are generally used in the classroom or hallways to reduce the noise levels or to create a softer walking surface and throw rugs are commonly used in classrooms to create a soft-sitting surface for younger students. However, carpets and throw rugs require maintenance and they do not clean as well as hard non-porous surfaces (floor tile). These fleecy materials become sinks or reservoirs where microorganisms accumulate (dust mites, bacteria and mold). If this material becomes wet and does not dry within 48 hours or if an object is placed on a wet carpet, preventing it from drying, fungus and bacterial will grow. Cleaning a carpet with fungal growth is difficult to accomplish and therefore, removal is usually the best option. Therefore, it is important that the throw carpet and pillows be periodically removed and cleaned. If occupants of the classroom develop an allergy, the practice of using carpet and/or cushions should be discontinued Asthma: A number of occupants openly indicated that they were either asthmatic or suffered from allergies or other respiratory illness. Americans spend up to 90% of their time indoors. Therefore, indoor allergens and irritants can play a significant role in triggering asthma attacks. Some of the most common indoor asthma triggers include secondhand smoke, dust mites, mold, cockroaches and other pests, household pets, and combustion byproducts Building Inspection: Internal Building Inspection: The affected rooms were inspected and appeared to be dry. A number of spaces had water stained ceiling tiles, water damaged / clutter cabinets beneath the sinks. 4.0 CONCLUSION 16

17 The indoor air samples had a MoldSCORE below 150, which indicates that there is a low probability that the spores originated inside the building. The average concentration for nuisance dust, formaldehyde, ozone, nitrogen dioxide carbon monoxide, carbon dioxide and total petroleum hydrocarbons, in all the spaces investigated, were below or equal to the outside sample.

They cannot be differentiated by non-viable sampling methods. Also, some species with very small spores are easily missed, and may be undercounted. Background debris indicates the amount of non-biological particulate matter present on the trace (dust in the air) and the resulting visibility for the analyst. It is rated from 1+ (low) to 4+ (high). Counts from areas with 4+ background debris should be regarded as minimal counts and may be higher than reported. It is important to account for samples volumes when evaluating dust levels. The analytical sensitivity is the spores/m^3 divided by the raw count, expressed in spores/m^3. The limit of detection is the analytical sensitivity (in spores/m^3) multiplied by the sample volume (in liters) divided by 0 liters. For more information regarding analytical sensitivity, please contact QA by calling the laboratory. A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is reflected by the value of "x". Total Spores/m3 has been rounded to two significant figures to reflect analytical precision. EMLab ID: , Page 18 of 52

The spores of Aspergillus and Penicillium (and others such as Acremonium, Paecilomyces) are small and round with very few distinguishing characteristics. They cannot be differentiated by non-viable sampling methods. Also, some species with very small spores are easily missed, and may be undercounted. Background debris indicates the amount of non-biological particulate matter present on the trace (dust in the air) and the resulting visibility for the analyst. It is rated from 1+ (low) to 4+ (high). Counts from areas with 4+ background debris should be regarded as minimal counts and may be higher than reported. It is important to account for samples volumes when evaluating dust levels. The analytical sensitivity is the spores/m^3 divided by the raw count, expressed in spores/m^3. The limit of detection is the analytical sensitivity (in spores/m^3) multiplied by the sample volume (in liters) divided by 0 liters.

The spores of Aspergillus and Penicillium (and others such as Acremonium, Paecilomyces) are small and round with very few distinguishing characteristics. They cannot be differentiated by non-viable sampling methods. Also, some species with very small spores are easily missed, and may be undercounted. Background debris indicates the amount of non-biological particulate matter present on the trace (dust in the air) and the resulting visibility for the analyst. It is rated from 1+ (low) to 4+ (high). Counts from areas with 4+ background debris should be regarded as minimal counts and may be higher than reported. It is important to account for samples volumes when evaluating dust levels. The analytical sensitivity is the spores/m^3 divided by the raw count, expressed in spores/m^3. The limit of detection is the analytical sensitivity (in spores/m^3) multiplied by the sample volume (in liters) divided by 0 liters. For more information regarding analytical sensitivity, please contact QA by calling the laboratory.

148 MoldSCORE : Spore Trap Report Location: Room 470 Basidiospores 2 80 Total 80 Date of Report: Final MoldSCORE 109 * The spores in this category are generally capable of growing on wet building materials in addition to growing outdoors. Building related growth is dependent upon the fungal type, moisture level, type of material, and other factors. Cladosporium is one of the predominant spore types worldwide and is frequently present in high numbers. Penicillium/Aspergillus species colonize both outdoor and indoor wet surfaces rapidly and are very easily dispersed. Other genera are usually present in lesser numbers. ** These fungi are generally not found growing on wet building materials. For example, the rusts and smuts are obligate plant pathogens. However, in each group there are notable exceptions. For example, agents of wood decay are members of the basidiomycetes and high counts of a single morphological type of basidiospore on an inside sample should be considered significant. The spores of Aspergillus and Penicillium (and others such as Acremonium, Paecilomyces) are small and round with very few distinguishing characteristics. They cannot be differentiated by non-viable sampling methods. Rated on a scale from to 300. A rating less than 150 is low and indicates a low probability of spores originating inside. A rating greater than 250 is high and indicates a high probability that the spores originated from inside, presumably from indoor mold growth. A rating between 150 and 250 indicates a moderate likelihood of indoor fungal growth. MoldSCORE is NOT intended for wall cavity samples. It is intended for ambient air samples in residences. Using the analysis on other samples (like wall cavity samples) will lead to misleading results. EMLab ID: , Page 51 of 51

Building related growth is dependent upon the fungal type, moisture level, type of material, and other factors. Cladosporium is one of the predominant spore types worldwide and is frequently present in high numbers. Penicillium/Aspergillus species colonize both outdoor and indoor wet surfaces rapidly and are very easily dispersed. Other genera are usually present in lesser numbers. ** These fungi are generally not found growing on wet building materials. For example, the rusts and smuts are obligate plant pathogens. However, in each group there are notable exceptions. For example, agents of wood decay are members of the basidiomycetes and high counts of a single morphological type of basidiospore on an inside sample should be considered significant. The spores of Aspergillus and Penicillium (and others such as Acremonium, Paecilomyces) are small and round with very few distinguishing characteristics.
