SAMPLES RECEIVED: 1
This is a final report from MouldWorks for the single bulk sample we received
October 5th, 2009, taken from your home at 35 Clinton St., Apt. #10,
Plattsburgh, NY. Here are your results.
1118-1 tape (Bathroom – Behind Shower)
Penicillium sp./Aspergillus sp.
Dry-spored Acremonium sp.
Our analysis of the above set of samples found abundant evidence of a mold
infestation in the bathroom sampled in this home. The sample contained viable
spores, vegetative cells and/or reproductive structures from a variety of fungal
species, including many molds which require moderately high to extremely high
levels of available moisture before they can colonize an indoor site. The
presence of these microorganisms can be directly attributed to elevated levels
of available moisture locally. Specifically, Stachybotrys requires a water
activity of at least 0.94 before it can germinate and colonize indoor sites.
Water activity is a measure of the proportion of moisture available to organisms
growing on a semi-solid substrate. Finding molds indoors that require such high
levels of moisture is a strong indication that this site has experienced
flooding, leaks or other water intrusion events. I gather from the chain of
custody form that the shower stall had been leaking for some time and this is
almost certainly the source of the moisture that supports these colonies.
Without first addressing the moisture problems behind the mold growth, molds
will undoubtedly continue to plague this site.
Due to the presence of several toxigenic mold species, I’d strongly recommend
having a professional come in and clean up the infestation properly to avoid
stirring up spores and risking further personal exposure. A professional mold
remediator will have the equipment and expertise needed to remove the colony
safely, under containment, ensuring that any spores released during the work are
removed from the building. It is important that any remediation job is
guaranteed with third-party air sampling for mold spores following completion.
Without this step, you have no way of knowing whether the project succeeds in
improving the indoor air quality
