Re: 202 Red Horse Squadron-Building 4285 A wing

Camp Blanding 5629 16 W. Stark, FL 32034

Thank you for giving The First Coast Mold Detectives the opportunity to serve you by providing our mold detection services.

Section 1

Building 4285 A wing - Camp Blanding

The Mold Detectives www.themolddetectives.com

Office 904-998-8584 http://www.themolddetectives.com/

The Mold Detectives was contacted to perform a mold assessment with air samples in building 4285 A wing, building 4286 B wing and building 4287 C wing in late January 2019. The Mold Detectives had performed a preliminary assessment and testing in one room of building 4285 and one room of building

4220 on September 14, 2018 and found elevated spore counts in both locations. The amount of visible suspected microbial growth found in several rooms and the spore counts in building 4285 necessitated further testing. See our report dated September 19, 2018

Dennis Williams, MRSA 2493, returned to building 4285 on November 9, 2018 to collect cavity samples in three locations in an effort to determine the extent of microbial growth. Cavity samples are collected from the spaces between the walls that separate the rooms. Samples were taken in rooms A4, A9 and

A14. All three locations had elevated spore counts with room A4 having the highest levels. See our report dated November 17, 2018

Dennis Williams returned on January 29, 2019 to take samples in buildings 4285, 4286 and 4287. The rooms sampled were spaced to better understand the scope of the contamination. The attic areas of each building were also sampled at either end. The samples were submitted to EMLab P&K an independent accredited microscopy laboratory. Lab ID# 173067.

The air samples were collected using Air O Cell cassettes. The sampling technique involved pumping 15 liters of air per minute for 5 minutes through each cassette for a total of 75 liters. The slides inside the cassettes were then evaluated under high power microscopy and a spore count analysis was then provided by EMLab P&K.

According to the ACGIH the proper way to evaluate airborne mold and particulate is to compare total spore counts between the baseline (exterior) sample and each indoor air sample quantity. After analyzing the EmLab P&K report we find the following:

Only elevated spore counts are reported here.

Note: Normally attic areas are not tested for air borne mold spores as attic air is considered “outside air”. The attics on buildings 4285, 4286 and 4287 are closed systems. While many attics are ventilated by way of eave vents, ridge vents or exhaust fan systems these attic areas have no such ventilation methods in use. This can trap heat, humidity and mold spores. This can, in some cases, contribute to moisture and mold issues in these enclosed environments and the living areas below.

Re: 202 Red Horse Squadron-Building 4286 B wing

Section 2

Building 4286 B wing – Camp Blanding

The Mold Detectives www.themolddetectives.com

A total of 8 air samples were collected from building 4286 B wing. The first sample was taken in the laundry followed by 5 dorm rooms and 2 samples from the attic area.

The air samples were collected using Air O Cell cassettes. The sampling technique involved pumping 15 liters of air per minute for 5 minutes through each cassette for a total of 75 liters. The slides inside the cassettes were then evaluated under high power microscopy and a spore count analysis was then provided by EMLab P&K.

The overall results showed elevated levels of Penicillium/Aspergillus only. All other spore counts were below those recorded outside.

A table in the dayroom. Close up of the underside of the table.

Game/TV cabinet in dayroom. Close up of the underside of a shelf in the game cabinet.

In building 4287 the dayroom and attic area contain the highest spore count elevations. The dayroom ceiling is a simple drop ceiling consisting of acoustic tiles in a metal framework. There is no other barrier between the dayroom and the attic area of C wing. The spore counts of Penicillium/Aspergillus in the attic area are very high and would easily account for the problems in the dayroom.

Conclusion

How individuals react to elevated spore counts of any mold species depends on personal physiology.

There are no established “safe” levels of mold spores.

Building 4285, A wing, has the highest spore counts within the rooms and will need the most intensive remediation efforts. In the interest of safety we recommend for the present time that the rooms in building 4285 remain unoccupied.

Building 4286, B wing, of the rooms tested the highest spore counts are on the west side of the building and on the north side of the attic. If visible suspected microbial growth is found in the occupied rooms in this building relocation of the students should be considered.

Building 4287, C wing, has the highest spore counts in the dayroom and the attic area.

Penicillium/Aspergillus spp. – Both Aspergillus and Penicillium are fairly common in the indoor environment. They are commonly present in higher levels indoors when compared to outdoors conditions. Increased levels of these spores indoors usually indicate a water intrusion/leak and/or elevated moisture conditions. Aspergillus/Penicillium spp. are very common worldwide. They can be isolated from air, plants, foodstuffs, soil, dust layers, garbage/compost, animal dung, cotton, cellulose, textiles, carpet, wallpaper, and in interior fiberglass duct insulation, painted surfaces, wood and fabric covered furniture and cotton fabrics. Some Aspergillus species are allergenic and other species produce powerful mycotoxins. Some of the species are one of the most common causes of systemic fungal disease in humans and animals causing primarily acute or chronic respiratory tract infections. All of the species contained in this genus should be considered allergenic. Some Penicillium species produce a mycotoxin. The Aspergillus/Penicillium spp. group represents fungal spores from a variety of fungal genera that can be indistinguishable from other similarly small, round (globose to sub-globose) fungal spores including, but not limited to the fungal genera; Acremonium, Botrytis, Gliocladium, Paeciliomyces, Trichoderma, Scopulariopsis, Wallemia, and many others. Common and important allergen. Common. Type I allergies (hay fever, asthma). Type III hypersensitivity pneumonitis: Cheese washer's lung, Woodman's lung, Moldy wall hypersensitivity. Widespread. Commonly found in house dust. Grows in water damaged buildings on wallpaper, wallpaper glue, decaying fabrics, moist chipboards, and behind paint. Also found in blue rot of apples, dried foodstuffs, cheeses, fresh herbs, spices, dry cereals, nuts, onions, and oranges.

Cladosporium is the most frequently found genus of fungi in outdoor air in temperate climates and the enzymes are especially suited for the breakdown of cellulose, pectin and lignin. There are more than

500 species that are found in both indoor and outdoor environments with an optimum growth rate at a temperature range of 18-28°C. Most colonies of Cladosporium spp. from typical indoor air samples are of outdoor origin. This is primarily due to their ability to rapidly invade many different habitats and easily disperse large numbers of spores. Studies have shown that as many as 10,000 spores / m3 of

Cladosporium spp. can be found in an outdoor sample in the summer. Cladosporium is isolated from air, dust, plants (decaying or alive), soil, textiles and wood. Cladosporium is also often encountered in dirty refrigerators, on moist window frames and anywhere condensation can occur (such isolation is not normally a cause for concern). There are no specific mycotoxins that are known to be produced by species of Cladosporium spp. Common and important allergen. Type I allergies (hay fever, asthma). Type

III hypersensitivity pneumonitis: Hot tub lung, Moldy wall hypersensitivity. Growth Indoors;

Widespread, on many substrates, including textiles, wood, moist window sills. Grows at 0°C, and so is associated with refrigerated foods.

Addendum 1

Basidiospores are a general category of sexual spores that have been released from the basidium of a fungus. This class contains the mushrooms, shelf fungi, puffballs, and a variety of other macro fungi.

Aubiquitous type I & III allergen, saprobe and plant pathogen, mainly found in gardens, forests, and woodlands. Spores disseminate during rain or in times of high humidity. Rarely opportunistic pathogens, many basidiomycete spores are reported to be allergenic. Basidiospores are an agent of dry wood rot, which may destroy the structure wood of buildings. The presence of Basidiospores in indoor air samples usually indicates an infiltration of outdoor air.
