Water damage in a home or building is the leading cause of microbial contamination. If not handled promptly and properly, bacteria and fungus can quickly colonize and grow, posing potential health risks for inhabitants. Health problems can occur depending upon the quality of water that causes the damage and the length of time before remediation.
There are three different categories of water quality:
There are a number of different fungal contaminants commonly found in water-damaged environments. Some of the most common include certain species of Aspergillus and Penicillium. These species tend to colonize in continuously damp materials and are commonly found in house dust and on water-damaged wallpaper, wallboards, and other household materials. Other molds found after water damage can include Stachybotrys chartarum, Trichoderma, Fusarium, as well as others. These fungi prefer to colonize in extremely wet environments such as soaked wallboards and water reservoirs. All of these fungi are considered potential toxin producers and the mycotoxins from these molds can cause health effects.
