Typically, there is no need for initial sampling if mold is visible. Occasionally, a customer is sensitive to mold and needs species and concentration information. We will collect air samples for analysis, by an independent laboratory, during inspections if it is requested. We offer this additional service so that property owners will be better informed of the condition of building interiors and the molds occupants may be exposed to. We always recommend clearance testing completed under separate contract with a reputable firm. For more information on qualified Indoor Air Quality consultants click here.
The OSHA website plainly states “…there are no federal standards or recommendations, (e.g., OSHA, NIOSH, EPA) for airborne concentrations of mold or mold spores. Scientific research on the relationship between mold exposures and health effects is ongoing.” OSHA provides a guideline of 1,000 viable colony forming units in a cubic meter of air.
We follow the OSHA guideline and remediate to lower concentrations of mold species (i.e, stachyboytrys, cladophialophora, and aspergillus) that have had a negative impact on some humans.
Kathleen Parrott, Ph.D. has impressive credentials. She completed undergraduate and graduate work at Cornell and earned her Ph.D. from the University of Nebraska. Her published work includes “Healthy Indoor Air for America’s Homes”, which was funded by the Environmental Protection Agency. On page 3 of “Mold Basics” she writes-
“Mold can grow very quickly. The spores of some varieties can begin to germinate in as little as 4 to 12 hours, if the environmental conditions are favorable. It can be assumed that when building materials get wet, mold growth is likely to start immediately. In wet porous materials, mold can become extensive within 24 to 48 hours.”
