Attempts to mitigate microbial contamination of a four story office building by use of common standard cleaning procedures proved inefficient by post abatement analytical results. Toxigenic, allergenic and pathogenic fungi were identified in sampling evaluation as a follow up to microbial abatement. Microorganisms such as Stachybotrys, Aspergillus, Penicillium, Cladosporium and Fusarium were detected in air and surface samples of a four story office building. Review of the chain of events revealed that microbial re-colonization, cross-contamination and recontamination had occurred at this facility.

IED, Inc. an environmental company specializing in microbial abatement and air quality restoration in indoor environments was commissioned to the project of biocidal clean-up and air quality restoration. Success of such projects are strictly dependent on applied scientific knowledge and experience. IED, Inc. successfully completed the biocidal and air quality restoration project as proven by post abatement analytical results performed by an independent third party monitoring company and laboratories.
