October 7, 2016 Mr. Robert Whartenby Facilities Manager Bensalem Township School District 3000 Donallen Drive Bensalem, PA 19020 Dear Mr. Whartenby, Diagnostic asbestos air samples and airborne mold air samples were collected at Bensalem High School on September 22, 2016. Asbestos Air Samples Six (6) diagnostic asbestos air samples were collected in selected corridor locations throughout both floors of the school facility. Phase Contrast Microscopy (PCM) analysis of these samples exhibited results of 0.004 fibers per cubic centimeter (f/cc) or less for all samples. These analysis results meet AHERA’s PCM air clearance standard following asbestos abatement procedures, and provide evidence that an airborne asbestos hazard did not exist within the areas sampled at the time of sampling. Please find enclosed the test report sheets for these air samples detailing analysis results and sample locations. Mold Air Samples Air samples were collected for analysis of airborne mold spores and other fungal structures. The following table is a summary of the analysis of the samples. Data detailing the quantities of individual spore types are outlined on the laboratory data pages included with this report.

Airborne mold sample results measured indoors were below the outdoor samples and had similar population dispersions. This is the desired condition inside a building regarding airborne mold spores. If you have any questions, please contact me at anytime. Sincerely,

Keith E. Crawford, CIH President

Report Date: 09/27/2016

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.

This report may not be reproduced in whole or in part without the expressed written consent from Eagle Industrial Hygiene Associates, Incorporated.

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.
