DETERMINING AFFECTED AREAS

DETERMINING THE EXTENT OF AIRBORNE CONTAMINATION

Microscopic mold spores are always present in the indoor air, normally at quantities from 30 to 80% of the outdoor levels. When mold growth occurs due to water damage or high humidity, mold colonies can send millions of spores airborne. The longer the mold grows unnoticed, to further the airborne contamination will extend. When spore counts are elevated throughout a home or building, the air in all areas should be treated. Below is an example of a Mold Analysis Report with elevated spore counts throughout the entire home. The air samples taken not only led to the source, but showed that every room needed to be included in remediation.

In the following mold analysis report, enough samples were taken to determine that airborne contamination had spread from the master bathroom to the master bedroom and to the adjacent living room, but not to the central family room. By determining which areas had elevated spores counts and which areas did not, containment can be established between affected and unaffected areas. Affected areas can be cleaned without the risk of cross-contamination of unaffected areas.
