Why do airborne mold samples sometimes not indicate that mold contamination is present, even when there is visible surface mold?
Mold growing on a surface is not necessarily producing airborne spores, especially in an area that has little or no activity in it such as an unfinished basement used primarily for storage. Also, if the surface that the mold is growing on is still damp or wet, the mold spores will not become airborne as easily. GML has found cases of significant amounts of active mold growth on wallboard without the companion air samples showing elevated mold spores.
