Intrusion of water into your home or place of business is an out of the ordinary event.  This could result from either water intrusion, long standing leaks, or from poor humidity control.  A water damage situation offers opportunities for mold spores that are normally present on surfaces to grow and multiply.  This is a good reason for promptly drying any water or moisture.  Moisture and humidity levels may be increased in a structure that has experienced water damage.  Organic materials found inside a building, such as wood, paper, drywall, and insulation, provide food sources for molds (given an adequate amount of moisture to flourish).  A water damage left unattended for any period of time may lead to mold growth, which in turn, leads to indoor environmental conditions that are “out of the ordinary.”
