Pre-Construction (Baseline) IEQ Evaluation Report Date: 6/21/2016


Project #160483

SCOPE

The pre-construction evaluation of the high school and middle school involved the completion of the

following tasks:

1. Inspecting the building structures, equipment, and processes to identify any items or conditions

which might negatively impact the indoor environment, including mold and water damage.

2. Reviewing the heating, ventilation, and air conditioning (HVAC) system operation parameters

and inspecting accessible HVAC equipment.

3. Surveying the buildings using an infrared camera to identify temperature differences that may be

associated with wet building materials.

4. Measuring the moisture content of building materials in areas of suspected water damage using a

two-pin relative moisture meter.

5. Evaluating ventilation airflow patterns using “chemical smoke” tubes.

6. Interviewing supervisory staff in each building to identify conditions or operations that may

impact the indoor environment.

7. Measuring relative humidity, temperature, carbon dioxide, carbon monoxide, and total volatile

organic compound (TVOC) concentrations in the buildings. The measurements were made with

direct-reading instruments at a height of 3-6 feet and a minimum of every 25,000 square feet of

floor space and in each functional space serviced by a separate ventilation system.

8. Measuring airborne formaldehyde levels at a total of eighteen (18) locations throughout the high

school and middle school, plus one (1) laboratory blank.

9. Measuring total airborne particulate as PM10 at a minimum of twenty (20) locations throughout

the high school and middle school.

10. Collecting air samples for mold analysis. The laboratory analysis counts and identifies the types

of molds collected in the samples. A minimum of thirty (30) air samples were collected within

the high school and middle school.

The samples collected during the evaluation were preserved and transported with a chain-of-custody

form to Eagle Industrial Hygiene Associates, Inc.’s laboratory (AIHA – IAQ EMLAP Accreditation

#100421) for evaluation of microbial content. Formaldehyde samples were shipped to Analytics

Corporation (#100531) in Ashland, VA. Detailed sample information and other supporting data are

included as attachments to the report.

All evaluation services were directed by a Certified Industrial Hygienist (CIH) and performed in

accordance with generally accepted industrial hygiene guidelines and other current applicable

governmental and industry organization protocols and guidelines for evaluating water damage and for

recommendations for water damage and mold growth related remediation activities in buildings.

The information outlined in this report is believed to be accurate and true to the best knowledge of the

inspector(s). The findings and recommendations contained in this report are based on the observations

of the conditions as they existed at the time of the evaluation.




Project #160483

SUMMARY

Air testing results indicated that the air quality within the schools was generally consistent throughout,

and typical with respect to a normal indoor school/office environment.

The air testing results and information associated with each exposure measurement are presented below

and in the attached Tables 1 through 3.

EXPOSURE STANDARDS

Several federal agencies and organizations promulgate occupational exposure limits (OELs) to prevent

the occurrence of adverse health effects from workplace exposures. Exposure limit values are typically

in terms of 8- to 10-hour time-weighted averages (TWAs). Generally, OELs suggest levels of exposure

to which most workers may be exposed up to 10 hours per day, 40 hours per week for a working lifetime

without experiencing adverse health effects. The Occupational Safety and Health Administration

(OSHA) Permissible Exposure Limit (PEL) is regulatory, while the NIOSH Recommended Exposure

Limit (REL) and the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold

Limit Value (TLV) are recommended guidelines.

Contaminant exposure limits applicable to the indoor environment are published in The American

Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) ANSI/ASHRAE Standard

62.1-2016, Ventilation for Acceptable Indoor Air Quality.

The LEED Standard for New Construction and Major Renovation, IEQ Credit 3.2, specifies acceptable

limits for formaldehyde, carbon monoxide, particulate matter, and total volatile organic compounds that

must be met prior to occupancy following construction or renovation.

AIR TESTING METHODS AND RESULTS

Direct-reading instruments were used to obtain real-time measurements of Carbon Dioxide (CO2),

Carbon Monoxide (CO), Volatile Organic Compounds (VOCs), Particulate Matter (PM10), Temperature

(Temp), and Relative Humidity (RH). The instruments were transported through the school to each

sampling location on a wheeled Audio/Video cart, with the instrument probes exposed to the ambient

air. At each sampling location, the instruments were set up at a height of 3-6 feet, and readings were

allowed to stabilize before being recorded on the Survey Data Log. Sample locations were selected in a

manner so as to obtain the minimum required density, while obtaining a dispersion of measurements that

would best characterize the quality of the air throughout the buildings. Air testing was conducted on

each day between 8:15 a.m. and 2:30 p.m. during normal student/staff occupancy.

The results obtained and presented in this report are representative of the conditions as they existed at

the time of the evaluation.




Project #160483

1) Carbon Dioxide

Carbon Dioxide (CO2) is a normal constituent of exhaled breath and is not considered a building air

pollutant. It can be used as an indicator of whether sufficient quantities of outdoor air are being

introduced by ventilation into an occupied space for acceptable odor control. Elevated CO2

concentrations suggest that other common indoor contaminants may also be increased. The

concentrations of CO2 found in most schools and offices are well below established occupational

exposure limits of 5,000 ppm as an 8-hour TWA. While levels below these limits are considered to pose

no serious health threat, studies indicate that individuals in schools and offices with elevated CO2

concentrations tend to report drowsiness, lethargy, and a general sense that the air is stale.

The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) notes in an

informative appendix to ANSI/ASHRAE Standard 62.1-2016 that indoor CO2 concentrations no greater

than 700 ppm above outdoor CO2 concentrations will satisfy a substantial majority of occupants with

regard to odor from sedentary building occupants. If CO2 concentrations are elevated, the amount of

outdoor air introduced into the ventilated space may need to be increased.

Method: CO2 concentration was measured at each location using a calibrated TSI Q-Trak Model 7565

Indoor Air Quality Monitor with a resolution of 1 ppm. The instrument was positioned at breathing

zone height (3-6 ft.) and allowed to stabilize before each reading.

Results: The CO2 measurement results are presented in Table 1.

The average of the CO2 measurements was 807 ppm, with a maximum measurement of 1,720 ppm, and

a minimum of 340 ppm. The ASHRAE-recommended guideline for CO2 of “no greater than 700 ppm

plus the outdoor CO2 concentration” was exceeded at five (19.2%) of the tested locations.

The locations where the ASHRAE guideline level was exceeded were within common areas, primarily

the pod hubs, which were fully occupied by students performing various activities. CO2 levels decreased

when the areas emptied during change intervals. These findings indicate that an adequate amount of

outdoor air was generally being introduced into the building spaces by the HVAC system.




Project #160483

2) Carbon Monoxide

Carbon monoxide (CO) is a colorless, odorless, tasteless gas that can be a product of the incomplete

combustion of organic compounds. CO combines with hemoglobin and interferes with the oxygen-

carrying capacity of blood. Symptoms include headache, drowsiness, dizziness, nausea, vomiting,

collapse, myocardial ischemia, and death.

The NIOSH REL for CO is 35 ppm for up to a 10-hour TWA. NIOSH also recommends a ceiling limit

of 200 ppm, which should not be exceeded at any time during the workday. The ACGIH TLV for an 8-

hour TWA is 25 ppm; the OSHA PEL for an 8-hour TWA is 50 ppm.

The indoor air quality limit for CO published in ANSI/ASHRAE Standard 62.1-2016 is 0.009 ppm.

The acceptable concentration under LEED EQ 3.2, Indoor Air Quality, is 0.009 ppm.

Method: CO concentration was measured at each location using a calibrated TSI Q-Trak Model 7565

Indoor Air Quality Monitor with a resolution of 0.1 ppm. The instrument was positioned at breathing

zone height (3-6 ft.) and allowed to stabilize before each reading.

Results: The CO measurement results are presented in Table 1.

All carbon monoxide measurements collected during the course of the air testing were less than the

instrument’s limit of detection, which was 0.1 ppm.

These findings indicate that CO concentrations were at acceptable levels.




Project #160483

3) Volatile Organic Compounds

Volatile organic compounds (VOCs) include a variety of carbon-based chemicals that are emitted as

gases from certain solids or liquids. The composition of VOCs makes it possible for them to evaporate

under normal indoor atmospheric conditions of temperature and pressure. Some VOCs may have short-

and long-term adverse health effects, depending on the magnitude and duration of exposure.

Concentrations of many VOCs are typically greater indoors than outdoors.

VOCs are emitted by a wide array of products, numbering in the thousands. Examples include: cleaning

products; paints and lacquers; paint strippers; pesticides; building furnishings; office equipment such as

copiers and printers; correction fluids and carbonless copy paper; graphics and craft materials including

glues and adhesives; permanent markers; and photographic solutions. Building materials, especially

new building materials, are potential VOC sources. New carpeting, backing, and adhesives; draperies;

particle and flake board; wood products that use certain glues, finishes, and waxes in the manufacturing

process; textile products, and vinyl-type flooring and wall coverings may all release VOCs into the air.

Many VOCs are irritants and can cause headaches, eye, nose and throat irritation and dizziness. Long-

term exposure to certain VOCs may lead to chronic diseases or cancer. At high concentrations, some

VOCs are toxic.

At the present time, there are no national or state exposure standards that are specific for school, office,

or home settings. In addition, there are many opinions in the science and medical communities about

the degree of risk posed by various amounts of VOCs. Exposure limits have been established, however,

for specific VOCs such as formaldehyde.

Method: The VOC concentration was measured at each location using a calibrated Rae Systems

MiniRAE 3000 Photoionization Detector (PID) with a resolution of 0.1 ppm. The instrument was

positioned at breathing zone height (3-6 ft.) and allowed to stabilize before each reading.

Results: The VOC measurement results are presented in Table 1.

All VOC measurements collected during the course of the air testing were equal to or less than the

instrument’s limit of detection, which was 0.1 ppm.

These findings indicate that VOC concentrations were at acceptable levels.




Project #160483

4) Temperature and Relative Humidity

Temperature (Temp) and relativity humidity (RH) are air quality factors that affect the perception of

comfort in an indoor environment. The perception of thermal comfort is related to an individual’s

metabolic heat production, the transfer of heat to the environment, physiological adjustments, and body

temperature. Heat transfer from the body to the environment is influenced by factors such as

temperature, humidity, air movement, personal activities, and clothing.

The ANSI/ASHRAE Standard 55-2004, Thermal Environmental Conditions for Human Occupancy,

specifies conditions under which a substantial majority of the occupants would be expected to find the

environment thermally acceptable. Assuming slow air movement (under 40 fpm) and 50% RH, the

operative temperatures recommended by ASHRAE range from 68.5ºF to 76ºF in the winter, and from

75ºF to 80.5ºF in the summer. The difference between the two is largely due to seasonal clothing

selection. An acceptable range of humidity levels is 30-60%. ASHRAE also recommends maintaining

RH at or below 65% because excessive humidity can promote the growth of microorganisms and dust

mites.

Method: Temperature and relative humidity were measured at each location using a calibrated TSI Q-

Trak Model 7565 Indoor Air Quality Monitor with a resolution of 0.1 ºF ppm for temperature, and 0.1%

for relative humidity. The instrument was positioned at breathing zone height (3-6 ft.) and allowed to

stabilize for each reading.

Results: The Temp and RH measurement results are presented in Table 1.

The average of the Temp measurements was 74 ºF, with a maximum measurement of 77 ºF, and a

minimum of 71 ºF. The ASHRAE-recommended guidelines for temperature were met at all locations.

The average of the RH measurements was 46 %, with a maximum measurement of 58 %, and a

minimum of 36 %. The ASHRAE recommended guideline for RH was met at all locations. There were

no measurements that deviated from the guideline levels.

These findings indicate that RH and Temp were within acceptable levels during the season collected.




Project #160483

5) Particulate Matter

Particulate matter (PM) is the name for a wide range of particles that are small enough to be carried by

the air and therefore be breathed in by people. They can be solid or liquid, or a mixture of both. The

size of particles may range from 0.005 µm to 100 µm in diameter. In comparison, the average diameter

of a human hair is 60 µm. PM10 is particulate matter comprised of particles that are 10 µm or less in

diameter. PM10 particles pose the greatest potential threat to human health because they are small

enough to travel deepest into the lungs.

The acceptable concentration under LEED EQ 3.2, Indoor Air Quality, is 0.500 mg/m3.

Method: Airborne particulate matter levels were measured at each location using a calibrated direct-

reading TSI Dust-Trak II Aerosol Monitor with a resolution of 0.001 mg/m3. The instrument was

positioned at breathing zone height (3-6 ft.) and allowed to stabilize before each reading.

Findings: The PM10 measurement results are presented in Table 1.

The average PM10 concentration was 0.013 mg/m3, with a maximum measurement of 0.027 mg/m

3, and

a minimum of 0.006 mg/m3.

Results indicate that particulate levels did not exceed established exposure limits, including

measurements obtained outdoors.

Direct-Reading Instrument Calibration

The TSI Q-Trak 7565 IAQ Monitor was zeroed and calibrated for CO2 and CO, using certified

calibration gases, prior to collecting measurements. Instrument zeros and calibration were checked each

day before and after use and, if necessary, the instrument was recalibrated. Temp and RH were

calibrated against an NIST traceable thermometer/hygrometer before and after use.

The MiniRAE 3000 PID was factory-calibrated and maintained by the instrument supplier and zero-

calibrated onsite.

The TSI Dust-Trak II Aerosol Monitor was factory-calibrated and maintained by the instrument

supplier.




Project #160483

6) Formaldehyde

Formaldehyde (HCHO) is a colorless chemical with a strong pungent odor. It is classified as a VOC and

is an important industrial chemical used to make such things as building materials and household

products. HCHO is found in glues, wood products, preservatives, permanent press fabrics, paper

product coatings, and certain insulation materials. Off-gassing of formaldehyde in new buildings can

occur with building materials and textiles. Products such as particleboard, cabinets and furniture,

plywood wall panels, and urea-formaldehyde insulation can off-gas formaldehyde gas.

The most commonly reported and best documented health complaints due to exposure to low

concentrations of formaldehyde include irritation of the eyes, nose, and throat; nasal congestion;

headaches; skin rash; and asthma.

Under the OSHA standard for airborne exposure to formaldehyde [29 CFR 1910.1048], the PEL is 0.75

ppm for an 8-hour TWA, the Action Level (AL) is 0.5 ppm for an 8-hour TWA, and the Short-term

Exposure Limit (STEL) is 2 ppm for a 15-minute TWA. The OSHA standard requires that special

requirements be met (e.g., medical surveillance) for employees exposed to formaldehyde at or above the

AL or STEL. The ACGIH lists formaldehyde as a sensitizer and established a ceiling limit of 0.3 ppm.

An ACGIH ceiling limit is an exposure that should not be exceeded at any time during a work shift.

HUD has established a level of 0.4 ppm for mobile homes. Based upon current information, it is

recommended by EPA to mitigate formaldehyde that is present at levels higher than 0.1 ppm.

The acceptable concentration under LEED EQ 3.2, Indoor Air Quality, is 0.027 ppm.

Method: Measurements of HCHO concentrations were collected using SKC UMEX Passive Samplers

for Formaldehyde. The samplers were set up at each location and allowed to collect an air sample for 24

hours. The samplers were submitted for analysis according to NIOSH Method 2016M by a laboratory

accredited under the American Industrial Hygiene Association LAP and ISO 17025:2009.

Results: Analysis results for formaldehyde air samples are presented in Table 2. Upon sample

retrieval, one (1) formaldehyde passive sampler (noted in table) was found to be missing.

The average result was 0.015 ppm, with a maximum result of 0.021 ppm, and a minimum of 0.007 ppm.

These findings indicate that formaldehyde concentrations were at acceptable levels.




Project #160483

7) Mold Spores

These biological components of fungi can arise from a host of means. Moisture buildup inside buildings

may arise from water penetrating compromised areas of the building envelope or skin, from plumbing

leaks, from condensation due to improper insulation or ventilation, or from ground moisture penetrating

a building part. In areas where cellulosic materials (wood and paper, including drywall surfaces)

become moist and fail to dry within 48 hours, mold can propagate and release potentially allergenic

spores into the air. Mold is always associated with moisture, and its growth can be inhibited by keeping

humidity levels below 65 %.

The primary hazard of mold growth, as it relates to indoor air quality, is associated with the allergenic

properties of the spore cell wall. More serious than most allergenic properties is the ability of mold to

trigger episodes in persons that already have asthma.

Clearly defined standards regarding “how much mold is too much” are not available. For airborne mold

spore samples, the desired condition is an indoor mold spore concentration that is much less than the

outdoor concentration. Also, it is not desirable for mold species on indoor mold spore samples to be

identified that are not present on the outdoor sample.

Method: Airborne mold spore samples were collected on Zefon Air-O-Cell® spore traps using a

battery-powered Zefon Bio-Pump Plus. The pump was calibrated to a flow rate of 15.0 l/min, and post-

calibrated to verify stability of the flow rate. Samples were analyzed in accordance with ASTM Method

D5075 by a laboratory accredited under the American Industrial Hygiene Association LAP and ISO

17025:2009.

Findings: Airborne mold spore results are presented in Table 3.

The airborne spore concentrations measured inside the school spaces were significantly less than the

concentrations found in the outdoor (control) samples, which is indicative of a normal indoor

environment. Also, the spore types on the indoor samples were consistent with those found in the

outdoor samples. These findings are an indication of normal or acceptable indoor fungal environment

conditions, and suggest that an active indoor mold problem did not exist. Data detailing the quantities of

individual spore types, as well as interpretive information, are presented in the attached laboratory test

reports.




Project #160483

Report Date: 06/14/2016

ASTM D7391 - 09 "Standard Test Method for Categorization and Quantification of Airborne Fungal Structures in an Inertial Impaction Sample by Optical Microscopy" was used for the analysis of these samples.

20% of the sample surface (26 traverses) was viewed to count the fungal structures in the sample, unless otherwise noted.

Per method, when 100 counts for a given spore type or structure is reached, the number of traverses (percent of sample surface) viewed to that point is noted, and these values are used to calculate the concentration for the given spore or structure type. This stoppage rule does not apply to water related spores- all 26 traverses are counted.

The structure concentration calculation uses the percentage of the sample trace (number of traverses) viewed to count each spore or structure type and the sample air volume.

The calculated structure concentrations are reported to two significant figures. The total structure concentration may not equal the sum of the individual results due to the rounding of the individual values.

The detection limit for the area of the sample which was viewed is one fungal spore or structure.

400X magnification was used to view the sample, unless otherwise noted.

A background debris rating of 2 to 4 indicates particulate matter may obscure a portion of the sample surface and result in underreporting of fungal structures.

A background debris rating of 5 indicates the sample is overloaded with particulate matter and the fungal structures cannot be counted. A new sample should be collected at a shorter time interval, or other measures should be taken to reduce the particle load.

The analysis results are not blank corrected, unless otherwise noted.

Air-O-Cell slit impactor cassettes were used to collect the samples, unless otherwise stated.

See the chain of custody document for sample times or volumes, the date(s) of sampling, and the dateof receipt of the samples by the laboratory.

The samples were received in acceptable condition unless otherwise noted on the individual samplepage.

The analysis relates only to the samples tested, and the "scope" of this report pertains only to those items tested and listed as such on the individual pages of this document.

Predominately Outside

Alternaria : considered an allergen, involved in Type I allergies and Type III hypersensitivity

ascospores: majority are non-disease causing; usually occurring in high humidity or wet conditions

basidiospores: may produce toxins, involved in Type I allergies and Type III hypersensitivity

Bipolaris/Drechslera/Helminthosporium/Exserohilum : causes Type I allergic reactions and a

common cause of allergic fungal sinusitis

Curvularia : causes Type I allergic reactions and a common cause of allergic fungal sinusitis

Epicoccum : a common Type I allergen

Myxomycetes : known to cause Type I allergies

Pithomyces : not known to be allergenic or pathogenic

Torula : known to be involved in Type I allergies

Inside/Outside

Cladosporium : a common and important allergen, involved in Type I allergies and Type III

hypersensitivity

Penicillium/Aspergillus : common allergens, involved in Type I allergies and Type III hypersensitivity

Paecilomyces : considered an allergen, involved in Type I allergies and Type III hypersensitivity

Botrytis : considered an allergen, involved in Type I allergies and Type III hypersensitivity

Water Damage

Chaetomium : known to cause Type I allergies and hypersensitivity

Stachybotrys : a producer of mycotoxin, involved in Type I allergies and hypersensitivity

Ulocladium : a major allergen, involved in Type I allergies

NOTES:

Type I hypersensitivity: is an allergic reaction provoked by re-exposure to an allergen; examples are

allergies and hay fever.

Type II hypersensitivity: involves autoimmune diseases; examples are rheumatic fever and autoimmune

hemolytic anemia.

Type III hypersensitivity: involves the immune system giving an inflammatory response in the body;

examples are respiratory pneumonitis and Farmer's Lung.
