Environmental Solutions Group ● 7 Maple Leaf Drive., Greensboro, NC 27401 ● 336-373-1538 ● www.Go-ESG.com 4 Report with Protocols for Remediation Environmental Solutions Group Leading people, companies and communities to live, work and prosper in a sustainable environment. o A slightly elevated (960 counts/m3) level of the pathogenic fungi Aspergillus/Penicillium-like was identified at the middle of the warehouse. o Slightly elevated (between 1,000 and 3,000 counts/m3) levels of the allergenic fungi Ascospores and Basidiospores were identified at the interior of the building near the left and right entry doors to the warehouse. o These fungal types appear outdoors at moderate levels and are generally found indoors at low or trace amounts. Direct Swab Findings: Surface samples for microbial analysis were collected in the warehouse for lab analysis (please see the “Chain of Custody” document below for specific locations). Below are the significant findings: • 8/4/21 report o An abundant (3) count of the allergenic fungi Cladosporium and a light (2) count of the pathogenic fungi Aspergillus/Penicillium-like were identified at the floor of the middle of the warehouse. o A loaded (4) count of the allergenic fungi Cladosporium and a trace (1) count of the pathogenic fungi Aspergillus/Penicillium-like were identified at the rack in the middle of the warehouse. • 9/14/20 report o Elevated counts (1-2) of the toxigenic fungi Chaetomium were identified at four of the six surface samples taken from items stored within the warehouse. ▪ These are slow growing fungi that produce toxins in spores which are poisonous by inhalation. These toxigenic types grow on building materials with high cellulose content and high moisture content, so it indicates a significant and generally a prolonged moisture source. ▪ Chaetomium is one of the five known as “zero tolerance” fungi in an indoor environment. • The lab uses a scoring system of 1 (trace), 2 (light), 3 (abundant), and 4 (loaded) to characterize the number of microbial spores identified in the sample. This scoring system is accepted by the IICRC S520 Standard for Professional Mold Remediation as indicative of normal fungal ecology should the score be a 1 or 2 (unless a zero tolerance fungi), and abnormal fungal ecology should the score be a 3 or 4. The lab also reports the number of hyphal fragments, or pieces of microbial material, which further support a characterization of either abnormal or normal fungal ecology. Observation: The findings of microbial growth and extremely elevated humidity within the warehouse indicate that the warehouse has been in a condition conducive to microbial growth. Randomized sampling of the surfaces within the warehouse reported on the 9/14/20 report indicated that the toxigenic fungi Chaetomium had been dispersed onto many of the surfaces and contents. Updated sampling and observation reported 8/4/21 indicated that the levels of airborne Aspergillus/Penicillium-like and Cladosporium were higher than before, and that these fungal types are on the surfaces of the warehouse at elevated amounts. It is also likely that additional Chaetomium spores also remain within the warehouse but were not identified in the limited surface sampling performed for the 8/4/21 report. These fungal spores likely originated from areas of dust accumulation where very high prolonged humidity allowed the fungi to grow. Natural disturbances within the warehouse from general air movement and human activity likely allowed this dust and fungi to become momentarily suspended in the air and land the contents. The tunnel containment (leading to the body cooler) had very clean particles counts and a very clean surface sample, indicating that the containment is continuing to be an effective barrier and is clean.
